Linux 5.5=rc1 kselftest rseq test build failure
by Shuah Khan
Hi Mathieu,
I am seeing rseq test build failure on Linux 5.5-rc1.
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./
param_test.c -lpthread -lrseq -o ...tools/testing/selftests/rseq/param_test
param_test.c:18:21: error: static declaration of ‘gettid’ follows
non-static declaration
18 | static inline pid_t gettid(void)
| ^~~~~~
In file included from /usr/include/unistd.h:1170,
from param_test.c:11:
/usr/include/x86_64-linux-gnu/bits/unistd_ext.h:34:16: note: previous
declaration of ‘gettid’ was here
34 | extern __pid_t gettid (void) __THROW;
| ^~~~~~
make: *** [Makefile:28: ...tools/testing/selftests/rseq/param_test] Error 1
The following obvious change fixes it. However, there could be reason
why this was defined here. If you think this is the right fix, I can
send the patch. I started seeing this with gcc version 9.2.1 20191008

[PATCH v8 00/26] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
This implements an API naming change (put_user_page*() -->
unpin_user_page*()), and also implements tracking of FOLL_PIN pages. It
extends that tracking to a few select subsystems. More subsystems will
be added in follow up work.
Christoph Hellwig, a couple of points of interest:
a) I've moved the bulk of the code out of the inline functions, as
requested, for the devmap changes (patch 4: "mm: devmap: refactor
1-based refcounting for ZONE_DEVICE pages").
b) Contrary to my earlier response to your review, I have not actually
merged patch 23 ("mm/gup: pass flags arg to __gup_device_*
functions") into patch 24 ("mm/gup: track FOLL_PIN pages"). This is
because I suspect that it's better to avoid making patch 24 any larger
and worse to review than it already is. But if you feel strongly
about it, I'll combine them anyway.
Changes since v7:
* Rebased onto Linux 5.5-rc1
* Reworked the grab_page() and try_grab_compound_head(), for API
consistency and less diffs (thanks to Jan Kara's reviews).
* Added Leon Romanovsky's reviewed-by tags for two of the IB-related
patches.
* patch 4 refactoring changes, as mentioned above.
There is a git repo and branch, for convenience:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v8
For the remaining list of "changes since version N", those are all in
v7, which is here:
https://lore.kernel.org/r/20191121071354.456618-1-jhubbard@nvidia.com
============================================================
Overview:
This is a prerequisite to solving the problem of proper interactions
between file-backed pages, and [R]DMA activities, as discussed in [1],
[2], [3], and in a remarkable number of email threads since about
2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
unpin_user_page()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've
been able to runtime test the core get_user_pages() and
pin_user_pages() and related routines, but not so much on several of
the call sites--but those are generally just a couple of lines
changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Runtime testing for the call sites so far is pretty light:
* io_uring: Some directed tests from liburing exercise this, and
they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and
passes.
* infiniband: ran "ib_write_bw", which exercises the umem.c changes,
but not the other changes.
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...

[PATCH] selftests: filesystems/epoll: fix build error

[PATCH AUTOSEL 4.19 026/177] selftests/bpf: Correct path to include msg + path
by Sasha Levin
From: Ivan Khoronzhuk <ivan.khoronzhuk(a)linaro.org>
[ Upstream commit c588146378962786ddeec817f7736a53298a7b01 ]
The "path" buf is supposed to contain path + printf msg up to 24 bytes.
It will be cut anyway, but compiler generates truncation warns like:
"
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c: In
function ‘setup_cgroup_environment’:
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:52:34:
warning: ‘/cgroup.controllers’ directive output may be truncated
writing 19 bytes into a region of size between 1 and 4097
[-Wformat-truncation=]
snprintf(path, sizeof(path), "%s/cgroup.controllers", cgroup_path);
^~~~~~~~~~~~~~~~~~~
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:52:2:
note: ‘snprintf’ output between 20 and 4116 bytes into a destination
of size 4097
snprintf(path, sizeof(path), "%s/cgroup.controllers", cgroup_path);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:72:34:
warning: ‘/cgroup.subtree_control’ directive output may be truncated
writing 23 bytes into a region of size between 1 and 4097
[-Wformat-truncation=]
snprintf(path, sizeof(path), "%s/cgroup.subtree_control",
^~~~~~~~~~~~~~~~~~~~~~~
cgroup_path);
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:72:2:
note: ‘snprintf’ output between 24 and 4120 bytes into a destination
of size 4097
snprintf(path, sizeof(path), "%s/cgroup.subtree_control",
cgroup_path);
"
In order to avoid warns, lets decrease buf size for cgroup workdir on
24 bytes with assumption to include also "/cgroup.subtree_control" to
the address. The cut will never happen anyway.

[PATCH AUTOSEL 5.4 327/350] libbpf: Fix call relocation offset calculation bug
by Sasha Levin
From: Andrii Nakryiko <andriin(a)fb.com>
[ Upstream commit a0d7da26ce86a25e97ae191cb90574ada6daea98 ]
When relocating subprogram call, libbpf doesn't take into account
relo->text_off, which comes from symbol's value. This generally works fine for
subprograms implemented as static functions, but breaks for global functions.
Taking a simplified test_pkt_access.c as an example:
__attribute__ ((noinline))
static int test_pkt_access_subprog1(volatile struct __sk_buff *skb)
{
return skb->len * 2;
}
__attribute__ ((noinline))
static int test_pkt_access_subprog2(int val, volatile struct __sk_buff *skb)
{
return skb->len + val;
}
SEC("classifier/test_pkt_access")
int test_pkt_access(struct __sk_buff *skb)
{
if (test_pkt_access_subprog1(skb) != skb->len * 2)
return TC_ACT_SHOT;
if (test_pkt_access_subprog2(2, skb) != skb->len + 2)
return TC_ACT_SHOT;
return TC_ACT_UNSPEC;
}
When compiled, we get two relocations, pointing to '.text' symbol. .text has
st_value set to 0 (it points to the beginning of .text section):
0000000000000008 000000050000000a R_BPF_64_32 0000000000000000 .text
0000000000000040 000000050000000a R_BPF_64_32 0000000000000000 .text
test_pkt_access_subprog1 and test_pkt_access_subprog2 offsets (targets of two
calls) are encoded within call instruction's imm32 part as -1 and 2,
respectively:
0000000000000000 test_pkt_access_subprog1:
0: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0)
1: 64 00 00 00 01 00 00 00 w0 <<= 1
2: 95 00 00 00 00 00 00 00 exit
0000000000000018 test_pkt_access_subprog2:

4: 04 00 00 00 02 00 00 00 w0 += 2
5: 95 00 00 00 00 00 00 00 exit
0000000000000000 test_pkt_access:

4: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0)
5: 64 02 00 00 01 00 00 00 w2 <<= 1
6: 5e 21 08 00 00 00 00 00 if w1 != w2 goto +8 <LBB0_3>

10: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0)
11: 04 02 00 00 02 00 00 00 w2 += 2
12: b4 00 00 00 ff ff ff ff w0 = -1
13: 1e 21 01 00 00 00 00 00 if w1 == w2 goto +1 <LBB0_3>
14: b4 00 00 00 02 00 00 00 w0 = 2
0000000000000078 LBB0_3:
15: 95 00 00 00 00 00 00 00 exit
Now, if we compile example with global functions, the setup changes.
Relocations are now against specifically test_pkt_access_subprog1 and
test_pkt_access_subprog2 symbols, with test_pkt_access_subprog2 pointing 24
bytes into its respective section (.text), i.e., 3 instructions in:
0000000000000008 000000070000000a R_BPF_64_32 0000000000000000 test_pkt_access_subprog1

Calls instructions now encode offsets relative to function symbols and are both
set ot -1:
0000000000000000 test_pkt_access_subprog1:
0: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0)

0000000000000080 LBB2_3:
16: 95 00 00 00 00 00 00 00 exit
Thus the right formula to calculate target call offset after relocation should
take into account relocation's target symbol value (offset within section),
call instruction's imm32 offset, and (subtracting, to get relative instruction
offset) instruction index of call instruction itself. All that is shifted by
number of instructions in main program, given all sub-programs are copied over
after main program.
Convert few selftests relying on bpf-to-bpf calls to use global functions
instead of static ones.

[PATCH AUTOSEL 5.4 307/350] selftests, bpf: Workaround an alu32 sub-register spilling issue
by Sasha Levin
From: Yonghong Song <yhs(a)fb.com>
[ Upstream commit 2ea2612b987ad703235c92be21d4e98ee9c2c67c ]
Currently, with latest llvm trunk, selftest test_progs failed obj
file test_seg6_loop.o with the following error in verifier:
infinite loop detected at insn 76
The byte code sequence looks like below, and noted that alu32 has been
turned off by default for better generated codes in general:
48: w3 = 100
49: *(u32 *)(r10 - 68) = r3
...
; if (tlv.type == SR6_TLV_PADDING) {
76: if w3 == 5 goto -18 <LBB0_19>
...
85: r1 = *(u32 *)(r10 - 68)
; for (int i = 0; i < 100; i++) {
86: w1 += -1
87: if w1 == 0 goto +5 <LBB0_20>
88: *(u32 *)(r10 - 68) = r1
The main reason for verification failure is due to partial spills at
r10 - 68 for induction variable "i".
Current verifier only handles spills with 8-byte values. The above 4-byte
value spill to stack is treated to STACK_MISC and its content is not
saved. For the above example:
w3 = 100
R3_w=inv100 fp-64_w=inv1086626730498
*(u32 *)(r10 - 68) = r3
R3_w=inv100 fp-64_w=inv1086626730498
...
r1 = *(u32 *)(r10 - 68)
R1_w=inv(id=0,umax_value=4294967295,var_off=(0x0; 0xffffffff))
fp-64=inv1086626730498
To resolve this issue, verifier needs to be extended to track sub-registers
in spilling, or llvm needs to enhanced to prevent sub-register spilling
in register allocation phase. The former will increase verifier complexity
and the latter will need some llvm "hacking".
Let us workaround this issue by declaring the induction variable as "long"
type so spilling will happen at non sub-register level. We can revisit this
later if sub-register spilling causes similar or other verification issues.

[PATCH AUTOSEL 5.4 306/350] selftests, bpf: Fix test_tc_tunnel hanging
by Sasha Levin
From: Jiri Benc <jbenc(a)redhat.com>
[ Upstream commit 3b054b7133b4ad93671c82e8d6185258e3f1a7a5 ]
When run_kselftests.sh is run, it hangs after test_tc_tunnel.sh. The reason
is test_tc_tunnel.sh ensures the server ('nc -l') is run all the time,
starting it again every time it is expected to terminate. The exception is
the final client_connect: the server is not started anymore, which ensures
no process is kept running after the test is finished.
For a sit test, though, the script is terminated prematurely without the
final client_connect and the 'nc' process keeps running. This in turn causes
the run_one function in kselftest/runner.sh to hang forever, waiting for the
runaway process to finish.
Ensure a remaining server is terminated on cleanup.

[PATCH AUTOSEL 5.4 267/350] bpf, testing: Workaround a verifier failure for test_progs
by Sasha Levin
From: Yonghong Song <yhs(a)fb.com>
[ Upstream commit b7a0d65d80a0c5034b366392624397a0915b7556 ]
With latest llvm compiler, running test_progs will have the following
verifier failure for test_sysctl_loop1.o:
libbpf: load bpf program failed: Permission denied
libbpf: -- BEGIN DUMP LOG ---
libbpf:
invalid indirect read from stack var_off (0x0; 0xff)+196 size 7
...
libbpf: -- END LOG --
libbpf: failed to load program 'cgroup/sysctl'
libbpf: failed to load object 'test_sysctl_loop1.o'
The related bytecode looks as below:
0000000000000308 LBB0_8:
97: r4 = r10
98: r4 += -288
99: r4 += r7
100: w8 &= 255
101: r1 = r10
102: r1 += -488
103: r1 += r8
104: r2 = 7
105: r3 = 0
106: call 106
107: w1 = w0
108: w1 += -1
109: if w1 > 6 goto -24 <LBB0_5>
110: w0 += w8
111: r7 += 8
112: w8 = w0
113: if r7 != 224 goto -17 <LBB0_8>
And source code:
for (i = 0; i < ARRAY_SIZE(tcp_mem); ++i) {
ret = bpf_strtoul(value + off, MAX_ULONG_STR_LEN, 0,
tcp_mem + i);
if (ret <= 0 || ret > MAX_ULONG_STR_LEN)
return 0;
off += ret & MAX_ULONG_STR_LEN;
}
Current verifier is not able to conclude that register w0 before '+'
at insn 110 has a range of 1 to 7 and thinks it is from 0 - 255. This
leads to more conservative range for w8 at insn 112, and later verifier
complaint.
Let us workaround this issue until we found a compiler and/or verifier
solution. The workaround in this patch is to make variable 'ret' volatile,
which will force a reload and then '&' operation to ensure better value
range. With this patch, I got the below byte code for the loop:
0000000000000328 LBB0_9:
101: r4 = r10
102: r4 += -288
103: r4 += r7
104: w8 &= 255
105: r1 = r10
106: r1 += -488
107: r1 += r8
108: r2 = 7
109: r3 = 0
110: call 106
111: *(u32 *)(r10 - 64) = r0
112: r1 = *(u32 *)(r10 - 64)
113: if w1 s< 1 goto -28 <LBB0_5>
114: r1 = *(u32 *)(r10 - 64)
115: if w1 s> 7 goto -30 <LBB0_5>
116: r1 = *(u32 *)(r10 - 64)
117: w1 &= 7
118: w1 += w8
119: r7 += 8
120: w8 = w1
121: if r7 != 224 goto -21 <LBB0_9>

[PATCH AUTOSEL 5.4 250/350] selftests: net: Fix printf format warnings on arm
by Sasha Levin
From: Masami Hiramatsu <mhiramat(a)kernel.org>
[ Upstream commit 670cd6849ea36ea4df2f2941cf4717dff8755abe ]
Fix printf format warnings on arm (and other 32bit arch).
- udpgso.c and udpgso_bench_tx use %lu for size_t but it
should be unsigned long long on 32bit arch.
- so_txtime.c uses %ld for int64_t, but it should be
unsigned long long on 32bit arch.

[PATCH AUTOSEL 5.4 245/350] selftests: proc: Make va_max 1MB
by Sasha Levin
From: Masami Hiramatsu <mhiramat(a)kernel.org>
[ Upstream commit 2f3571ea71311bbb2cbb9c3bbefc9c1969a3e889 ]
Currently proc-self-map-files-002.c sets va_max (max test address
of user virtual address) to 4GB, but it is too big for 32bit
arch and 1UL << 32 is overflow on 32bit long.
Also since this value should be enough bigger than vm.mmap_min_addr
(64KB or 32KB by default), 1MB should be enough.
Make va_max 1MB unconditionally.

[ Upstream commit f90415e9600c5227131531c0ed11514a2d3bbe62 ]
test_progs never created a copy of subtest name, rather just stored
pointer to whatever string test provided. This is bad as that string
might be freed or modified by the end of subtest. Fix this by creating
a copy of given subtest name when subtest starts.

[PATCH AUTOSEL 5.4 056/350] selftests/bpf: Correct path to include msg + path
by Sasha Levin
From: Ivan Khoronzhuk <ivan.khoronzhuk(a)linaro.org>
[ Upstream commit c588146378962786ddeec817f7736a53298a7b01 ]
The "path" buf is supposed to contain path + printf msg up to 24 bytes.
It will be cut anyway, but compiler generates truncation warns like:
"
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c: In
function ‘setup_cgroup_environment’:
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:52:34:

[-Wformat-truncation=]
snprintf(path, sizeof(path), "%s/cgroup.controllers", cgroup_path);
^~~~~~~~~~~~~~~~~~~
samples/bpf/../../tools/testing/selftests/bpf/cgroup_helpers.c:52:2:
note: ‘snprintf’ output between 20 and 4116 bytes into a destination

warning: ‘/cgroup.subtree_control’ directive output may be truncated

cgroup_path);

note: ‘snprintf’ output between 24 and 4120 bytes into a destination
of size 4097
snprintf(path, sizeof(path), "%s/cgroup.subtree_control",
cgroup_path);
"
In order to avoid warns, lets decrease buf size for cgroup workdir on
24 bytes with assumption to include also "/cgroup.subtree_control" to
the address. The cut will never happen anyway.

[PATCH linux-kselftest/test v2] apparmor: add AppArmor KUnit tests for policy unpack
by Brendan Higgins
From: Mike Salvatore <mike.salvatore(a)canonical.com>
Add KUnit tests to test AppArmor unpacking of userspace policies.
AppArmor uses a serialized binary format for loading policies. To find
policy format documentation see
Documentation/admin-guide/LSM/apparmor.rst.
In order to write the tests against the policy unpacking code, some
static functions needed to be exposed for testing purposes. One of the
goals of this patch is to establish a pattern for which testing these
kinds of functions should be done in the future.

[PATCH v2] selftests: fix build behaviour on targets' failures
by Cristian Marussi
Currently, when some of the KSFT subsystems fails to build, the toplevel
KSFT Makefile just keeps carrying on with the build process.
This behaviour is expected and desirable especially in the context of a CI
system running KSelfTest, since it is not always easy to guarantee that the
most recent and esoteric dependencies are respected across all KSFT TARGETS
in a timely manner.
Unfortunately, as of now, this holds true only if the very last of the
built subsystems could have been successfully compiled: if the last of
those subsystem instead failed to build, such failure is taken as the whole
outcome of the Makefile target and the complete build/install process halts
even though many other preceding subsytems were in fact already built
successfully.
Fix the KSFT Makefile behaviour related to all/install targets in order
to fail as a whole only when the all/install targets have failed for all
of the requested TARGETS, while succeeding when at least one of TARGETS
has been successfully built.

This patch is based on ksft/fixes branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git
on top of commit (~5.5-rc1):
99e51aa8f701 Documentation: kunit: add documentation for kunit_tool
Building with either:
make kselftest-install \
KSFT_INSTALL_PATH=/tmp/KSFT \
TARGETS="exec arm64 bpf"
make -C tools/testing/selftests install \
KSFT_INSTALL_PATH=/tmp/KSFT \
TARGETS="exec arm64 bpf"
(with 'bpf' not building clean on my setup in the above case)
and veryfying that build/install completes if at least one of TARGETS can
be successfully built, and any successfully built subsystem is installed.
Changes:
-------
V1 --> V2
- rebased on 5.5-rc1
- rewording commit message
- dropped RFC tag

[PATCH 0/3] Reanme the definitions of INTERRUPT_PENDING, NMI_PENDING and TSC_OFFSETING
by Xiaoyao Li
When reading the codes, I find the definitions of interrupt-window exiting and
nmi-window exiting don't match the names in latest intel SDM.
I have no idea whether it's the historical names, rename them to match the
latest SDM to avoid confusion.
CPU_BASED_USE_TSC_OFFSETING mis-spelling in Patch 3 is found by checkpatch.pl.
Xiaoyao Li (3):
KVM: VMX: Rename INTERRUPT_PENDING to INTERRUPT_WINDOW
KVM: VMX: Rename NMI_PENDING to NMI_WINDOW
KVM: VMX: Fix the spelling of CPU_BASED_USE_TSC_OFFSETTING

[PATCH] selftests: net: ip_defrag: increase netdev_max_backlog
by Thadeu Lima de Souza Cascardo
When using fragments with size 8 and payload larger than 8000, the backlog
might fill up and packets will be dropped, causing the test to fail. This
happens often enough when conntrack is on during the IPv6 test.
As the larger payload in the test is 10000, using a backlog of 1250 allow
the test to run repeatedly without failure. At least a 1000 runs were
possible with no failures, when usually less than 50 runs were good enough
for showing a failure.
As netdev_max_backlog is not a pernet setting, this sets the backlog to
1000 during exit to prevent disturbing following tests.

[PATCH v18 00/13] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v18:
* Further fixups from Al Viro:
- Don't WARN_ON in complete_walk() check since it can be trivially
triggered by userspace. Also, improve the comment so the purpose of the
check is more clear.
- Avoid duplicate smp_rmb() when in handle_dots() by doing
__read_seqcount_retry().
- Drop vestigial UPGRADE_NO* flag definitions in uapi.
* Update non-zero __padding test to include all bytes of the padding.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file does not exist, it may
optionally (if O_CREAT is specified in how.flags) be created by openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the directory referred to by
the file descriptor dirfd (or the current working directory of the calling process, if dirfd is the special
value AT_FDCWD.) If pathname is absolute, then dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT,
in which case pathname is resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its functionality. Rather
than taking a single flag argument, an extensible structure (how) is passed instead to allow for future exten-
sions. size must be set to sizeof(struct open_how), to facilitate future extensions (see the "Extensibility"
section of the NOTES for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of the flag and mode
arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above structure (or
through reuse of pre-existing padding space), with the zero value of the new fields acting as though the ex-
tension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the O_* flags defined for
openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to openat(2). How-
ever, unlike openat(2), it is an error to provide openat2() with a mode which contains bits
other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not contain O_CREAT or O_TMP-
FILE.
resolve
Change how the components of pathname will be resolved (see path_resolution(7) for background
information.) The primary use case for these flags is to allow trusted programs to restrict how
untrusted paths (or paths inside untrusted directories) are resolved. The full list of resolve
flags is given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including all bind mounts).
Users of this flag are encouraged to make its use configurable (unless it is used for a
specific security purpose), as bind mounts are very widely used by end-users. Setting
this flag indiscrimnately for all uses of openat2() may result in spurious errors on pre-
viously-functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This option implies RE-
SOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both O_PATH and O_NOFOL-
LOW, then an O_PATH file descriptor referencing the symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (unless it is used for a
specific security purpose), as symbolic links are very widely used by end-users. Setting
this flag indiscrimnately for all uses of openat2() may result in spurious errors on pre-
viously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both O_PATH and O_NOFOLLOW,
then an O_PATH file descriptor referencing the magic link will be returned.
Magic-links are symbolic link-like objects that are most notably found in proc(5) (exam-
ples include /proc/[pid]/exe and /proc/[pid]/fd/*.) Due to the potential danger of un-
knowingly opening these magic links, it may be preferable for users to disable their res-
olution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the resolution is not a
descendant of the directory indicated by dirfd. This results in absolute symbolic links
(and absolute values of pathname) to be rejected.
Currently, this flag also disables magic link resolution. However, this may change in
the future. The caller should explicitly specify RESOLVE_NO_MAGICLINKS to ensure that
magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though the user called ch-
root(2) with dirfd as the argument.) Absolute symbolic links and ".." path components
will be scoped to dirfd. If pathname is an absolute path, it is also treated relative to
dirfd.
However, unlike chroot(2) (which changes the filesystem root permanently for a process),
RESOLVE_IN_ROOT allows a program to efficiently restrict path resolution for only certain
operations. It also has several hardening features (such detecting escape attempts dur-
ing .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However, this may change in
the future. The caller should explicitly specify RESOLVE_NO_MAGICLINKS to ensure that
magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2), as well as the fol-
lowing additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see the "Extensibility"
section of the NOTES for more detail on how extensions are handled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could not ensure that a ".."
component didn't escape (due to a race condition or potential attack.) Callers may choose to retry the
openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the root during path
resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic link (or magic
link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic link.
VERSIONS
openat2() first appeared in Linux 5.6.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using syscall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2() requires userspace
to specify the size of struct open_how structure they are passing. By providing this information, it is pos-
sible for openat2() to provide both forwards- and backwards-compatibility — with size acting as an implicit
version number (because new extension fields will always be appended, the size will always increase.) This
extensibility design is very similar to other system calls such as perf_setattr(2), perf_event_open(2), and
clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size of the structure
which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used verbatim.
* If ksize is larger than usize, then there are some extensions the kernel supports which the
userspace program is unaware of. Because all extensions must have their zero values be a no-op, the
kernel treats all of the extension fields not set by userspace to have zero values. This provides
backwards-compatibility.
* If ksize is smaller than usize, then there are some extensions which the userspace program is aware
of but the kernel does not support. Because all extensions must have their zero values be a no-op,
the kernel can safely ignore the unsupported extension fields if they are all-zero. If any unsup-
ported extension fields are non-zero, then -1 is returned and errno is set to E2BIG. This provides
forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of extensions. However, if a
userspace program wishes to determine what extensions the running kernel supports, they may conduct a binary
search on size (to find the largest value which doesn't produce an error of E2BIG.)

[PATCH v5 linux-kselftest-test 0/6] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 3.
Changes since v4:
- fixed signoff chain to use Co-developed-by: prior to Knut's signoff
(Stephen, all patches)
- added Reviewed-by, Tested-by for patches 1, 2, 4 and 6
- updated comment describing try-catch-impl.h (Stephen, patch 2)
- fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5)
- added __init to kunit_init() (Stephen, patch 5)
Changes since v3:
- removed symbol lookup patch for separate submission later
- removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed
with Brendan and Stephen)
- disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this
is to avoid having to deal with symbol lookup issues
- changed string-stream-impl.h back to string-stream.h (Brendan)
- added module build support to new list, ext4 tests
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported
symbols (patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: allow kunit tests to be loaded as a module
kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

selftests: l2tp tests
by Colin Ian King
Hi,
While testing linux 5.4 with the l2tp test I discovered two kernel
issues when running this test:
1. About 10+ seconds after completing the test one can observe periodic
kernel log messages from netdev_wait_allrefs (in net/core/dev.c) in the
form:
"unregister_netdevice: waiting for eth0 to become free. Usage count = 1"
2. Our regression tests that ran stress-ng after this test picked up
another issue that causes socket() to hang indefinitely. I've managed
to get this down to a simple reproducer as follows:
sudo modprobe l2tp_core
sudo ./linux/tools/testing/selftests/net/l2tp.sh
sleep 5
./close
Where ./close is an executable compiled from:
#include <sys/types.h>
#include <sys/socket.h>
#include <unistd.h>
#include <stdio.h>
int main()
{
int fd;
printf("calling socket..\n");
fd = socket(AF_APPLETALK, SOCK_STREAM, 0);
printf("socket returned: %d\n", fd);
}
The code will hang on the socket() call and won't ever get to the final
print statement.
If one runs the reproducer on earlier kernels we get:
4.6.7 crash (see dmesg below)
4.7.10 crash in xfrm6_dst_ifdown
4.8.17 crash in xfrm6_dst_ifdown
4.12.14 crash (see dmesg below)
4.13.16 reports "unregister_netdevice: waiting for eth0 to become free.
Usage count = 2"
4.14.157 reports "unregister_netdevice: waiting for eth0 to become free.
Usage count = 2""
4.15.18 .. 5.4 hangs on socket() call
Note: functionality for the l2tp test is not available for pre-4.6 kernels.
The crashes I get for older kernels are:

[PATCH v7 00/25] Unify vDSOs across more architectures
by Vincenzo Frascino
vDSO (virtual dynamic shared object) is a mechanism that the Linux
kernel provides as an alternative to system calls to reduce where
possible the costs in terms of cycles.
This is possible because certain syscalls like gettimeofday() do
not write any data and return one or more values that are stored
in the kernel, which makes relatively safe calling them directly
as a library function.
Even if the mechanism is pretty much standard, every architecture
in the last few years ended up implementing their own vDSO library
in the architectural code.
The purpose of this patch-set is to identify the commonalities in
between the architectures and try to consolidate the common code
paths, starting with gettimeofday().
This implementation contains the following design choices:
* Every architecture defines the arch specific code in an header in
"asm/vdso/".
* The generic implementation includes the arch specific one and lives
in "lib/vdso".
* The arch specific code for gettimeofday lives in
"<arch path>/vdso/gettimeofday.c" and includes the generic code only.
* The generic implementation of update_vsyscall and update_vsyscall_tz
lives in kernel/vdso and provide the bindings that can be implemented
by each architecture.
* Each architecture provides its implementation of the bindings in
"asm/vdso/vsyscall.h".
* This approach allows to consolidate the common code in a single place
with the benefit of avoiding code duplication.
This implementation contains the portings to the common library for: arm64,
compat mode for arm64, arm, mips, x86_64, x32, compat mode for x86_64 and
i386.
The mips porting has been tested on qemu for mips32el. A configuration to
repeat the tests can be found at [4].
The x86_64 porting has been tested on an Intel Xeon 5120T based machine
running Ubuntu 18.04 and using the Ubuntu provided defconfig.
The i386 porting has been tested on qemu using the i386_defconfig
configuration.
Last but not least from this porting arm64, compat arm64, arm and mips gain
the support for:
* CLOCK_BOOTTIME that can be useful in certain scenarios since it keeps
track of the time during sleep as well.
* CLOCK_TAI that is like CLOCK_REALTIME, but uses the International
Atomic Time (TAI) reference instead of UTC to avoid jumping on leap
second updates.
for both clock_gettime and clock_getres.
The porting has been validated using the vdsotest test-suite [1] extended
to cover all the clock ids [2].
A new test has been added to the linux kselftest in order to validate the
newly added library.
The porting has been benchmarked and the performance results are
provided as part of this cover letter.
To simplify the testing, a copy of the patchset on top of a recent linux
tree can be found at [3] and [4].
The v7 of this patchseries has been rebased on [5].

[PATCH v3 0/5] Fix nits in the kunit
by SeongJae Park
This patchset contains trivial fixes for the kunit documentations and the
wrapper python scripts.
Changes from v2 (https://lore.kernel.org/linux-kselftest/1575361141-6806-1-git-send-email-sj…):
- Make 'build_dir' if not exists (missed from v3 by mistake)
SeongJae Park (5):
docs/kunit/start: Use in-tree 'kunit_defconfig'
kunit: Remove duplicated defconfig creation
kunit: Create default config in '--build_dir'
kunit: Place 'test.log' under the 'build_dir'
kunit: Rename 'kunitconfig' to '.kunitconfig'

[BUGFIX PATCH] selftests/x86: Check the availablity of sys/syscall.h
by Masami Hiramatsu
Since single_step_syscall.c depends on sys/syscall.h and
its include, asm/unistd.h, we should check the availability
of those headers.
Without this fix, if gcc-multilib is not installed but
libc6-dev-i386 is installed, kselftest tries to build 32bit
binary and failed with following error message.
In file included from single_step_syscall.c:18:
/usr/include/sys/syscall.h:24:10: fatal error: asm/unistd.h: No such file or directory
#include <asm/unistd.h>
^~~~~~~~~~~~~~
compilation terminated.

[PATCH v4 0/5] Fix nits in the kunit
by SeongJae Park
This patchset contains trivial fixes for the kunit documentations and the
wrapper python scripts.
Changes from v3
(https://lore.kernel.org/linux-kselftest/20191204192141.GA247851@google.com):
- Fix the 4th patch, "kunit: Place 'test.log' under the 'build_dir'" to set
default value of 'build_dir' as '' instead of NULL so that kunit can run
even though '--build_dir' option is not given.
Changes from v2
(https://lore.kernel.org/linux-kselftest/1575361141-6806-1-git-send-email-sj…):
- Make 'build_dir' if not exists (missed from v3 by mistake)
Changes from v1
(https://lore.kernel.org/linux-doc/1575242724-4937-1-git-send-email-sj38.par…):
- Remove "docs/kunit/start: Skip wrapper run command" (A similar approach is
ongoing)
- Make 'build_dir' if not exists
SeongJae Park (5):
docs/kunit/start: Use in-tree 'kunit_defconfig'

[PATCH kselftest-next 1/2] kselftests: memcg: update the oom group leaf events test
by Roman Gushchin
Commit 9852ae3fe529 ("mm, memcg: consider subtrees in memory.events") made
memory.events recursive: all events are propagated upwards by the
tree. It was a change in semantics.
It broke the oom group leaf events test: it assumes that after
an OOM the oom_kill counter is zero on parent's level.
Let's adjust the test: it should have similar expectations
for the child and parent levels.
The test passes after this fix.

[PATCH v4 0/4] PM / QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY
by Leonard Crestez
Support for frequency limits in dev_pm_qos was removed when cpufreq was
switched to freq_qos, this series attempts to restore it by
reimplementing on top of freq_qos.
Discussion about removal is here:
https://lore.kernel.org/linux-pm/VI1PR04MB7023DF47D046AEADB4E051EBEE680@VI1…
The cpufreq core switched away because it needs contraints at the level
of a "cpufreq_policy" which cover multiple cpus so dev_pm_qos coupling
to struct device was not useful. Cpufreq could only use dev_pm_qos by
implementing an additional layer of aggregation anyway.
However in the devfreq subsystem scaling is always performed on a per-device
basis so dev_pm_qos is a very good match. Support for dev_pm_qos in devfreq
core is here (latest version, no dependencies outside this series):
https://patchwork.kernel.org/cover/11252409/
That series is RFC mostly because it needs these PM core patches.
Earlier versions got entangled in some locking cleanups but those are
not strictly necessary to get dev_pm_qos functionality.
In theory if freq_qos is extended to handle conflicting min/max values then
this sharing would be valuable. Right now freq_qos just ties two unrelated
pm_qos aggregations for min and max freq.
---
This is implemented by embeding a freq_qos_request inside dev_pm_qos_request:
the data field was already an union in order to deal with flag requests.
The internal freq_qos_apply is exported so that it can be called from
dev_pm_qos apply_constraints.
The dev_pm_qos_constraints_destroy function has no obvious equivalent in
freq_qos and the whole approach of "removing requests" is somewhat dubios:
request objects should be owned by consumers and the list of qos requests
will most likely be empty when the target device is deleted. Series follows
current pattern for dev_pm_qos.
First two patches can be applied separately.
Changes since v3:
* Fix s/QOS/QoS in patch 2 title
* Improves comments in kunit test
* Fix assertions after freq_qos_remove_request
* Remove (c) from NXP copyright header
* Wrap long lines in qos.c to be under 80 chars. This fixes checkpatch but the
rule is already broken by code in the files.
* Collect reviews
Link to v3: https://patchwork.kernel.org/cover/11260627/
Changes since v2:
* #define PM_QOS_MAX_FREQUENCY_DEFAULT_VALUE FREQ_QOS_MAX_DEFAULT_VALUE
* #define FREQ_QOS_MAX_DEFAULT_VALUE S32_MAX (in new patch)
* Add initial kunit test for freq_qos, validating the MAX_DEFAULT_VALUE found
by Matthias and another recent fix. Testing this should be easier!
Link to v2: https://patchwork.kernel.org/cover/11250413/
Changes since v1:
* Don't rename or EXPORT_SYMBOL_GPL the freq_qos_apply function; just
drop the static marker.

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.
by Iurii Zaikin
Fixes the issue caused by the fact that in C in the expression
of the form -1234L only 1234L is the actual literal, the unary
minus is an operation applied to the literal. Which means that
to express the lower bound for the type one has to negate the
upper bound and subtract 1.
Original error:
Expected test_data[i].expected.tv_sec == timestamp.tv_sec, but
test_data[i].expected.tv_sec == -2147483648

[GIT PULL] seccomp updates for v5.5-rc1
by Kees Cook
Hi Linus,
Please pull these seccomp updates for v5.5-rc1. Mostly this is
implementing the new flag SECCOMP_USER_NOTIF_FLAG_CONTINUE, but there
are cleanups as well. Most notably, the secure_computing() prototype
has changed (to remove an unused argument), but this has happened at the
same time as riscv adding seccomp support, so the cleanest merge order
would be to merge riscv first, then seccomp with the following patch for
riscv to handle the change from "seccomp: simplify secure_computing()":
diff --git a/arch/riscv/kernel/ptrace.c b/arch/riscv/kernel/ptrace.c

[PATCH v7 00/24] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
OK, here is v7, maybe this is the last one. The corresponding git repo
and branch is:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v7
Ira, you reviewed the gup_benchmark patches a bit earlier, but I
removed one or two of those review-by tags, due to invasive changes
I made after your review (in response to further reviews).
So could you please reply to any patches you'd like to have
reviewed-by's restoredto, if any? Mainly I'm thinking of
"mm/gup_benchmark: support pin_user_pages() and related calls". Also
various FOLL_LONGTERM vs pin_longterm*() patches.
The following blurb from the v6 cover letter is still applicable, and
I'll repeat it here so it doesn't get lost in the patch blizzard:
Christoph Hellwig has a preference to do things a little differently,
for the devmap cleanup in patch 5 ("mm: devmap: refactor 1-based
refcounting for ZONE_DEVICE pages"). That came up in a different
review thread, because the patch is out for review in two locations.
Here's that review thread:
https://lore.kernel.org/r/20191118070826.GB3099@infradead.org
...and I'm hoping that we can defer that request, because otherwise
it derails this series, which is starting to otherwise look like
it could be ready for 5.5.
Changes since v6:
* Renamed a couple of routines, to get rid of unnecessary leading
underscores:
__pin_compound_head() --> grab_compound_head()
__record_subpages() --> record_subpages()
* Fixed the error fallback (put_compound_head()) so as to match the fix
in the previous version: need to put back N * GUP_PIN_COUNTING_BIAS
pages, for FOLL_PIN cases.
* Factored out yet another common chunk of code, into a new grab_page()
routine.
* Added a missing compound_head() call to put_compound_head().
* [Re-]added Jens Axboe's reviewed-by tag to the fs/io_uring patch.
* Added more reviewed-by's from Jan Kara.
Changes since v5:
* Fixed the refcounting for huge pages: in most cases, it was
only taking one GUP_PIN_COUNTING_BIAS's worth of refs, when it
should have been taking one GUP_PIN_COUNTING_BIAS for each subpage.
(Much thanks to Jan Kara for spotting that one!)
* Renamed user_page_ref_inc() to try_pin_page(), and added a new
try_pin_compound_head(). This definitely improves readability.
* Factored out some more duplication in the FOLL_PIN and FOLL_GET
cases, in gup.c.
* Fixed up some straggling "get_" --> "pin_" references in the comments.
* Added reviewed-by tags.
Changes since v4:
* Renamed put_user_page*() --> unpin_user_page().
* Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM
at the call sites. (FOLL_PIN, however, remains an internal gup flag).
This is very nice: many patches just change three characters now:
get_user_pages --> pin_user_pages. I think we've found the right
balance of wrapper calls and gup flags, for the call sites.
* Updated a lot of documentation and commit logs to match the above
two large changes.
* Changed gup_benchmark tests and run_vmtests, to adapt to one less
use case: there is no pin_longterm_pages() call anymore.
* This includes a new devmap cleanup patch from Dan Williams, along
with a rebased follow-up: patches 4 and 5, already mentioned above.
* Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"),
so as to make pin_user_pages*() calls act as placeholders for the
corresponding get_user_pages*() calls, until a later patch fully
implements the DMA-pinning functionality.
Thanks to Jan Kara for noticing that.
* Fixed the implementation of pin_user_pages_remote().
* Further tweaked patch 2 ("mm/gup: factor out duplicate code from four
routines"), in response to Jan Kara's feedback.
* Dropped a few reviewed-by tags due to changes that invalidated
them.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-9: refactoring and preparatory cleanup, independent fixes
* Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 11-16: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 17: Activate tracking of FOLL_PIN pages.
* Patches 18-20: convert various callers
* Patches: 21-23: gup_benchmark and run_vmtests support
* Patch 24: rename put_user_page*() --> unpin_user_page*()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH] tools/testing/selftests/seccomp: change USER_NOTIF_MAGIC definition
by Max Filippov
USER_NOTIF_MAGIC is used to both initialize seccomp_notif_resp::val and
verify syscall resturn value. On 32-bit architectures syscall return
value has type long, but the value of USER_NOTIF_MAGIC has type long
long because it doesn't fit into long. As a result all syscall return
value comparisons with USER_NOTIF_MAGIC are false. This is also reported
by the compiler when '-W' is added to CFLAGS.
Add explicit type cast to USER_NOTIF_MAGIC definition.
This fixes the following seccomp_bpf tests on 32-bit architectures:
global.user_notification_basic
global.user_notification_child_pid_ns
global.user_notification_sibling_pid_ns
global.user_notification_fault_recv

[PATCH v24 14/24] selftests/x86: Add a selftest for SGX
by Jarkko Sakkinen
Add a selftest for SGX. It is a trivial test where a simple enclave
copies one 64-bit word of memory between two memory locations given to
the enclave as arguments. Use ENCLS[EENTER] to invoke the enclave.

[PATCH v2 00/19] pin_user_pages(): reduced-risk series for Linux 5.5
by John Hubbard
Hi,
Changes since v1:
* Fixed up ppc in response to Jan Kara's review comments (thanks for
those!).
* Fixed a kbuilt robot-detected build failure: added a stub function for
the !CONFIG_MMU case.
* Cover letter: now refers to "unpin_user_page()", reflecting the name
change in the last patch (instead of put_user_page() ).
* Rebased onto today's linux-next: c165016bac27 ("Add linux-next
specific files for 20191125")
========================================================================
Here is a set of well-reviewed (expect for one patch), lower-risk items
that can go into Linux 5.5. (Update: the powerpc conversion patch has
had some initial review now, since v1 was posted.)
This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages:
FOLL_PIN" [1], and with one of the VFIO patches split into two patches.
The idea here is to get this long list of "noise" checked into 5.5, so
that the actual, higher-risk "track FOLL_PIN pages" (which is deferred:
not part of this series) will be a much shorter patchset to review.
For the v4l2-core changes, I've left those here (instead of sending
them separately to the -media tree), in order to get the name change
done now (put_user_page --> unpin_user_page). However, I've added a Cc
stable, as recommended during the last round of reviews.
Here are the relevant notes from the original cover letter, edited to
match the current situation:
This is a prerequisite to tracking dma-pinned pages. That in turn is a
prerequisite to solving the larger problem of proper interactions
between file-backed pages, and [R]DMA activities, as discussed in [1],
[2], [3], and in a remarkable number of email threads since about
2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
unpin_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
unpin_user_page()

[PATCH v3 00/19] x86/cpu: Clean up handling of VMX features
by Sean Christopherson
Clean up a handful of interrelated warts in the kernel's handling of VMX:
- Enable VMX in IA32_FEATURE_CONTROL during boot instead of on-demand
during KVM load to avoid future contention over IA32_FEATURE_CONTROL.
- Rework VMX feature reporting so that it is accurate and up-to-date,
now and in the future.
- Consolidate code across CPUs that support VMX.
This series stems from two separate but related issues. The first issue,
pointed out by Boris in the SGX enabling series[1], is that the kernel
currently doesn't ensure the IA32_FEATURE_CONTROL MSR is configured during
boot. The second issue is that the kernel's reporting of VMX features is
stale, potentially inaccurate, and difficult to maintain.
Please holler if you don't want to be cc'd on future versions of this
series, or only want to be cc'd on select patches.
v3:
- Rebase to tip/master, ceceaf1f12ba ("Merge branch 'WIP.x86/cleanups'").
- Rename the feature control MSR bit defines [Boris].
- Rewrite the error message displayed when reading feature control MSR
faults on a VMX capable CPU to explicitly state that it's likely a
hardware or hypervisor issue [Boris].
- Collect a Reviewed-by for the LMCE change [Boris].
- Enable VMX in feature control (if it's unlocked) if and only if
KVM is enabled [Paolo].
- Remove a big pile of redudant MSR defines from the KVM selftests that
was discovered when renaming the feature control defines.
- Fix a changelog typoe [Boris].
v2:
- Rebase to latest tip/x86/cpu (1edae1ae6258, "x86/Kconfig: Enforce...)
- Collect Jim's reviews.
- Fix a typo in setting of EPT capabilities [TonyWWang-oc].
- Remove defines for reserved VMX feature flags [Paolo].
- Print the VMX features under "flags" and maintain all existing names
to be backward compatible with the ABI [Paolo].
- Create aggregate APIC features to report FLEXPRIORITY and APICV, so
that the full feature *and* their associated individual features are
printed, e.g. to aid in recognizing why an APIC feature isn't being
used.
- Fix a few copy paste errors in changelogs.
v1 cover letter:
== IA32_FEATURE_CONTROL ==
Lack of IA32_FEATURE_CONTROL configuration during boot isn't a functional
issue in the current kernel as the majority of platforms set and lock
IA32_FEATURE_CONTROL in firmware. And when the MSR is left unlocked, KVM
is the only subsystem that writes IA32_FEATURE_CONTROL. That will change
if/when SGX support is enabled, as SGX will also want to fully enable
itself when IA32_FEATURE_CONTROL is unlocked.
== VMX Feature Reporting ==
VMX features are not enumerated via CPUID, but instead are enumerated
through VMX MSRs. As a result, new VMX features are not automatically
reported via /proc/cpuinfo.
An attempt was made long ago to report interesting and/or meaningful VMX
features by synthesizing select features into a Linux-defined cpufeatures
word. Synthetic feature flags worked for the initial purpose, but the
existence of the synthetic flags was forgotten almost immediately, e.g.
only one new flag (EPT A/D) has been added in the the decade since the
synthetic VMX features were introduced, while VMX and KVM have gained
support for many new features.
Placing the synthetic flags in x86_capability also allows them to be
queried via cpu_has() and company, which is misleading as the flags exist
purely for reporting via /proc/cpuinfo. KVM, the only in-kernel user of
VMX, ignores the flags.
Last but not least, VMX features are reported in /proc/cpuinfo even
when VMX is unusable due to lack of enabling in IA32_FEATURE_CONTROL.
== Caveats ==
All of the testing of non-standard flows was done in a VM, as I don't
have a system that leaves IA32_FEATURE_CONTROL unlocked, or locks it with
VMX disabled.
The Centaur and Zhaoxin changes are somewhat speculative, as I haven't
confirmed they actually support IA32_FEATURE_CONTROL, or that they want to
gain "official" KVM support. I assume they unofficially support KVM given
that both CPUs went through the effort of enumerating VMX features. That
in turn would require them to support IA32_FEATURE_CONTROL since KVM will
fault and refuse to load if the MSR doesn't exist.

[PATCH] selftests: pmtu: use -oneline for ip route list cache
by Thadeu Lima de Souza Cascardo
Some versions of iproute2 will output more than one line per entry, which
will cause the test to fail, like:
TEST: ipv6: list and flush cached exceptions [FAIL]
can't list cached exceptions
That happens, for example, with iproute2 4.15.0. When using the -oneline
option, this will work just fine:
TEST: ipv6: list and flush cached exceptions [ OK ]
This also works just fine with a more recent version of iproute2, like
5.4.0.
For some reason, two lines are printed for the IPv4 test no matter what
version of iproute2 is used. Use the same -oneline parameter there instead
of counting the lines twice.

kselftest: failed to build with -C tool/testing/selftests when KBUILD_OUTPUT is set
by Cristian Marussi
Hi
while testing on linux-next
I see that, when KBUILD_OUTPUT is set in the env, running something like (using TARGETS=exec as a random subsystem here...)
$ make TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next kselftest-install
works fine as usual, WHILE the alternative invocation (still documented in Documentation/dev-tools/kselftest.rst)
make -C tools/testing/selftests/ TARGETS=exec INSTALL_PATH=/nfs/LTP-official-debian-aarch64-rootfs/opt/KSFT_next install
fails miserably with:
...
...

/home/crimar01/ARM/dev/src/pdsw/linux/Makefile:1187: recipe for target 'headers_install' failed
make[2]: *** [headers_install] Error 1
This is fixed by unsetting KBUILD_OUTPUT OR reverting:
303e6218ecec (ksft/fixes) selftests: Fix O= and KBUILD_OUTPUT handling for relative paths
since bypassing top makefile with -C, the definition of abs-objtree used by the above patch
is no more available.
As a side effect when KBUILD_OUTPUT is set, this breaks also the usage kselftest_install.sh.

A possible fix would be (but duplicates in fact the main Makefile logic)

Any thoughts ? ... or am I missing something ?
(I think I'm starting to see this in latest CI linaro kselftest while they cross-compile for arm64)

selftests:netfilter: nft_nat.sh: internal00-0 Error Could not open file \"-\" No such file or directory

Do you see the following error while running selftests netfilter
nft_nat.sh test ?
Are we missing any kernel config fragments ? We are merging configs
from the directory.

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.
by Iurii Zaikin
Fixes the issue caused by the fact that in C in the expression
of the form -1234L only 1234L is the actual literal, the unary
minus is an operation applied to the literal. Which means that
to express the lower bound for the type one has to negate the
upper bound and subtract 1.

[PATCH] kunit: test: Improve error messages for kunit_tool when kunitconfig is invalid
by Heidi Fahim
Previous error message for invalid kunitconfig was vague. Added to it so
that it lists invalid fields and prompts for them to be removed. Added
validate_config function returning whether or not this kconfig is valid.

[PATCH v3 0/4] PM: QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY
by Leonard Crestez
Support for frequency limits in dev_pm_qos was removed when cpufreq was
switched to freq_qos, this series attempts to restore it by
reimplementing on top of freq_qos.
Discussion about removal is here:
https://lore.kernel.org/linux-pm/VI1PR04MB7023DF47D046AEADB4E051EBEE680@VI1…
The cpufreq core switched away because it needs contraints at the level
of a "cpufreq_policy" which cover multiple cpus so dev_pm_qos coupling
to struct device was not useful. Cpufreq could only use dev_pm_qos by
implementing an additional layer of aggregation anyway.
However in the devfreq subsystem scaling is always performed on a per-device
basis so dev_pm_qos is a very good match. Support for dev_pm_qos in devfreq
core is here:
https://patchwork.kernel.org/cover/11252409/
That series is RFC mostly because it needs these PM core patches.
Earlier versions got entangled in some locking cleanups but those are
not strictly necessary to get dev_pm_qos functionality.
In theory if freq_qos is extended to handle conflicting min/max values then
this sharing would be valuable. Right now freq_qos just ties two unrelated
pm_qos aggregations for min and max freq.
---
This is implemented by embeding a freq_qos_request inside dev_pm_qos_request:
the data field was already an union in order to deal with flag requests.
The internal freq_qos_apply is exported so that it can be called from
dev_pm_qos apply_constraints.
The dev_pm_qos_constraints_destroy function has no obvious equivalent in
freq_qos and the whole approach of "removing requests" is somewhat dubios:
request objects should be owned by consumers and the list of qos requests
should be empty when the target device is deleted.
Changes since v2:
* #define PM_QOS_MAX_FREQUENCY_DEFAULT_VALUE FREQ_QOS_MAX_DEFAULT_VALUE
* #define FREQ_QOS_MAX_DEFAULT_VALUE S32_MAX (in new patch)
* Add initial kunit test for freq_qos, validating the MAX_DEFAULT_VALUE found
by Matthias.
Link to v2: https://patchwork.kernel.org/cover/11250413/
First two patches can be applied separated
Changes since v1:
* Don't rename or EXPORT_SYMBOL_GPL the freq_qos_apply function; just
drop the static marker.

[BUGFIX PATCH v3 0/4] selftests/ftrace: Fix ftracetest testcases for non-function tracer case
by Masami Hiramatsu
Hi,
Here is the 3rd version of patches to fix some issues which happens on
the kernel with CONFIG_FUNCTION_TRACER=n or CONFIG_DYNAMIC_FTRACE=n.
In this version and v2, I updated the descriptions of the first 2 patches
according to Steve's comment, added Steve's Reviewed-by to the 3rd patch,
and added the 4th patch which was newly found.
Thank you,

[PATCH v8 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter
by Mina Almasry
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.
Problem:
Currently tasks attempting to allocate more hugetlb memory than is available get
a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1].
However, if a task attempts to allocate hugetlb memory only more than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call,
but will SIGBUS the task when it attempts to fault the memory in.
We have developers interested in using hugetlb_cgroups, and they have expressed
dissatisfaction regarding this behavior. We'd like to improve this
behavior such that tasks violating the hugetlb_cgroup limits get an error on
mmap/shmget time, rather than getting SIGBUS'd when they try to fault
the excess memory in.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time.
Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and
the offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This
counter has slightly different semantics than
hugetlb.xMB.[limit|usage]_in_bytes:
- While usage_in_bytes tracks all *faulted* hugetlb memory,
reservation_usage_in_bytes tracks all *reserved* hugetlb memory and
hugetlb memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than reservation_limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage. We also added cgroup-v2 support to
hugetlb_cgroup so that the new use cases can be extended to v2.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to
the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters under
hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that modifies
the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at
reservation time rather than fault time. Adding a new page_counter seems
better as userspace could, if it wants, choose to enforce different cgroups
differently: one via limit_in_bytes, and another via
reservation_limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and reservation_limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- libhugetlbfs tests mostly passing, but some tests have trouble with and
without this patch series. Seems environment issue rather than code:

[PATCH 00/19] pin_user_pages(): reduced-risk series for Linux 5.5
by John Hubbard
Hi,
Here is a set of well-reviewed (expect for one patch), lower-risk items
that can go into Linux 5.5. The one patch that wasn't reviewed is the
powerpc conversion, and it's still at this point a no-op, because
tracking isn't yet activated.
This is based on linux-next: b9d3d01405061bb42358fe53f824e894a1922ced
("Add linux-next specific files for 20191122").
This is essentially a cut-down v8 of "mm/gup: track dma-pinned pages:
FOLL_PIN" [1], and with one of the VFIO patches split into two patches.
The idea here is to get this long list of "noise" checked into 5.5, so
that the actual, higher-risk "track FOLL_PIN pages" (which is deferred:
not part of this series) will be a much shorter patchset to review.
For the v4l2-core changes, I've left those here (instead of sending
them separately to the -media tree), in order to get the name change
done now (put_user_page --> unpin_user_page). However, I've added a Cc
stable, as recommended during the last round of reviews.
Here are the relevant notes from the original cover letter, edited to
match the current situation:
This is a prerequisite to tracking dma-pinned pages. That in turn is a
prerequisite to solving the larger problem of proper interactions
between file-backed pages, and [R]DMA activities, as discussed in [1],
[2], [3], and in a remarkable number of email threads since about
2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()

[BUGFIX PATCH v2 0/3] selftests/ftrace: Fix ftracetest testcases for non-function tracer case
by Masami Hiramatsu
Hi,
Here is the 2nd version of patches to fix some issues which happens on
the kernel with CONFIG_FUNCTION_TRACER=n or CONFIG_DYNAMIC_FTRACE=n.
In this version I just updated the descriptions of the first 2 patches
according to Steve's comment and add his Reviewed-by to the last patch.
Thank you,

[PATCH] selftests: Load settings from subdirs
by Kees Cook
If settings files are present in upper directories of a test directory,
load those first before the local settings. This allows a top-level
directory to define settings for subdirectories while still allowing the
subdirectories to override them on a per-directory basis.

+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

[PATCH v4 linux-kselftest-test 0/6] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 3.
Changes since v3:
- removed symbol lookup patch for separate submission later
- removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed
with Brendan and Stephen)
- disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this
is to avoid having to deal with symbol lookup issues
- changed string-stream-impl.h back to string-stream.h (Brendan)
- added module build support to new list, ext4 tests
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported
symbols (patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: allow kunit tests to be loaded as a module
kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH v6 00/24] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
Christoph Hellwig has a preference to do things a little differently,
for the devmap cleanup in patch 5 ("mm: devmap: refactor 1-based
refcounting for ZONE_DEVICE pages"). That came up in a different
review thread, because the patch is out for review in two locations.
Here's that review thread:
https://lore.kernel.org/r/20191118070826.GB3099@infradead.org
...and I'm hoping that we can defer that request, because otherwise
it derails this series, which is starting to otherwise look like
it could be ready for 5.5.
There is a git repo and branch, for convenience:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v6
Changes since v5:
* Fixed the refcounting for huge pages: in most cases, it was
only taking one GUP_PIN_COUNTING_BIAS's worth of refs, when it
should have been taking one GUP_PIN_COUNTING_BIAS for each subpage.
(Much thanks to Jan Kara for spotting that one!)
* Renamed user_page_ref_inc() to try_pin_page(), and added a new
try_pin_compound_head(). This definitely improves readability.
* Factored out some more duplication in the FOLL_PIN and FOLL_GET
cases, in gup.c.
* Fixed up some straggling "get_" --> "pin_" references in the comments.
* Added reviewed-by tags.
Changes since v4:
* Renamed put_user_page*() --> unpin_user_page().
* Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM
at the call sites. (FOLL_PIN, however, remains an internal gup flag).
This is very nice: many patches just change three characters now:
get_user_pages --> pin_user_pages. I think we've found the right
balance of wrapper calls and gup flags, for the call sites.
* Updated a lot of documentation and commit logs to match the above
two large changes.
* Changed gup_benchmark tests and run_vmtests, to adapt to one less
use case: there is no pin_longterm_pages() call anymore.
* This includes a new devmap cleanup patch from Dan Williams, along
with a rebased follow-up: patches 4 and 5, already mentioned above.
* Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"),
so as to make pin_user_pages*() calls act as placeholders for the
corresponding get_user_pages*() calls, until a later patch fully
implements the DMA-pinning functionality.
Thanks to Jan Kara for noticing that.
* Fixed the implementation of pin_user_pages_remote().
* Further tweaked patch 2 ("mm/gup: factor out duplicate code from four
routines"), in response to Jan Kara's feedback.
* Dropped a few reviewed-by tags due to changes that invalidated
them.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-9: refactoring and preparatory cleanup, independent fixes
* Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 11-16: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 17: Activate tracking of FOLL_PIN pages.
* Patches 18-20: convert various callers
* Patches: 21-23: gup_benchmark and run_vmtests support
* Patch 24: rename put_user_page*() --> unpin_user_page*()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH RESEND v17 00/13] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
This is a re-send of
<https://lore.kernel.org/lkml/20191117011713.13032-1-cyphar@cyphar.com/>
but rebased on top of 5.4-rc8 (also my mails got duplicated the first
time I sent v17 -- hopefully that doesn't happen this time).
Patch changelog:
v17:
* Add a path_is_under() check for LOOKUP_IS_SCOPED in complete_walk(), as a
last line of defence to ensure that namei bugs will not break the contract
of LOOKUP_BENEATH or LOOKUP_IN_ROOT.
* Update based on feedback by Al Viro:
* Make nd_jump_link() free the passed path on error, so that callers don't
need to worry about it in the error path.
* Remove needless m_retry and r_retry variables in handle_dots().
* Always return -ECHILD from follow_dotdot_rcu().

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+========================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash

[PATCH v5 00/24] mm/gup: track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
Please note that two of these patches are also out for review
separately, and may go in earlier than this series. This series
requires those, so to ease review and testing, they are also
included here: patches 4 and 5, the devmap cleanups.
There is a git repo and branch, for convenience:
git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v5
Despite the large number of changes, it does feel like the review
comments are converging, btw.
Changes since v4:
* Renamed put_user_page*() --> unpin_user_page().
* Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM
at the call sites. (FOLL_PIN, however, remains an internal gup flag).
This is very nice: many patches just change three characters now:
get_user_pages --> pin_user_pages. I think we've found the right
balance of wrapper calls and gup flags, for the call sites.
* Updated a lot of documentation and commit logs to match the above
two large changes.
* Changed gup_benchmark tests and run_vmtests, to adapt to one less
use case: there is no pin_longterm_pages() call anymore.
* This includes a new devmap cleanup patch from Dan Williams, along
with a rebased follow-up: patches 4 and 5, already mentioned above.
* Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"),
so as to make pin_user_pages*() calls act as placeholders for the
corresponding get_user_pages*() calls, until a later patch fully
implements the DMA-pinning functionality.
Thanks to Jan Kara for noticing that.
* Fixed the implementation of pin_user_pages_remote().
* Further tweaked patch 2 ("mm/gup: factor out duplicate code from four
routines"), in response to Jan Kara's feedback.
* Dropped a few reviewed-by tags due to changes that invalidated
them.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-9: refactoring and preparatory cleanup, independent fixes
* Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 11-16: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 17: Activate tracking of FOLL_PIN pages.
* Patches 18-20: convert various callers
* Patches: 21-23: gup_benchmark and run_vmtests support
* Patch 24: rename put_user_page*() --> unpin_user_page*()
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v4 0/2] HMM tests and minor fixes
by Ralph Campbell
These changes are based on Jason's rdma/hmm branch (5.4.0-rc5).
Patch 1 was previously posted here [1] but was dropped from that orginal
series. Hopefully, the tests will reduce concerns about edge conditions.
I'm sure more tests could be usefully added but I thought this was a good
starting point.
Changes since v3:
patch 1:
Unchanged except rebased on Jason's latest hmm (bbe3329e354d3ab5dc18).
patch 2:
Is now part of Jason's tree.
patch 3 (now 2):
Major changes to incorporate Jason's review feedback.
* drivers/char/hmm_dmirror.c driver moved to lib/test_hmm.c
* XArray used instead of "page tables".
* platform device driver removed.
* remove redundant copyright.
Changes since v2:
patch 1:
Removed hmm_range_needs_fault() and just use hmm_range_need_fault().
Updated the change log to include that it fixes a bug where
hmm_range_fault() incorrectly returned an error when no fault is requested.
patch 2:
Removed the confusing change log wording about DMA.
Changed hmm_range_fault() to return the PFN of the zero page like any other
page.
patch 3:
Adjusted the test code to match the new zero page behavior.
Changes since v1:
Rebased to Jason's rdma/hmm branch (5.4.0-rc1).
Cleaned up locking for the test driver's page tables.
Incorporated Christoph Hellwig's comments.

Ralph Campbell (2):
mm/hmm: make full use of walk_page_range()
mm/hmm/test: add self tests for HMM

[PATCH v17 00/13] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v17:
* Add a path_is_under() check for LOOKUP_IS_SCOPED in complete_walk(), as a
last line of defence to ensure that namei bugs will not break the contract
of LOOKUP_BENEATH or LOOKUP_IN_ROOT.
* Update based on feedback by Al Viro:
* Make nd_jump_link() free the passed path on error, so that callers don't
need to worry about it in the error path.
* Remove needless m_retry and r_retry variables in handle_dots().
* Always return -ECHILD from follow_dotdot_rcu().

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH v16 00/12] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v16:
* Update based on review by Al Viro:
* Handle magic-link related errors from with nd_jump_link() and drop
LOOKUP_MAGICLINK_JUMPED.
* Drop the slash-skipping logic for LOOKUP_IN_ROOT since it's not actually
necessary (link_path_walk() already does it, and it's possible that doing
it slightly breaks downstream code).
* Update outdated open_how documentation to match new semantics.
* Update commit message to further explain why -EAGAIN is preferable for
path_is_under() when checking whether ".." is safe.
* Split out the set_root() and nd_jump_root() errors from the
LOOKUP_BENEATH patch.
* Expand path-lookup documentation changes to describe all new LOOKUP flags.
* Cleanup the signature of ns_get_path() such that it returns an int
(previously it returned a void * -- even though the only two
possible return values were ERR_PTR or NULL).

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH AUTOSEL 4.14 090/150] selftests/powerpc/signal: Fix out-of-tree build
by Sasha Levin
From: Joel Stanley <joel(a)jms.id.au>
[ Upstream commit 27825349d7b238533a47e3d98b8bb0efd886b752 ]
We should use TEST_GEN_PROGS, not TEST_PROGS. That tells the selftests
makefile (lib.mk) that those tests are generated (built), and so it
adds the $(OUTPUT) prefix for us, making the out-of-tree build work
correctly.
It also means we don't need our own clean rule, lib.mk does it.
We also have to update the signal_tm rule to use $(OUTPUT).

[PATCH AUTOSEL 4.14 072/150] selftests: watchdog: fix message when /dev/watchdog open fails
by Sasha Levin
From: "Shuah Khan (Samsung OSG)" <shuah(a)kernel.org>
[ Upstream commit 9a244229a4b850b11952a0df79607c69b18fd8df ]
When /dev/watchdog open fails, watchdog exits with "watchdog not enabled"
message. This is incorrect when open fails due to insufficient privilege.
Fix message to clearly state the reason when open fails with EACCESS when
a non-root user runs it.

[PATCH AUTOSEL 4.19 117/237] selftests: watchdog: fix message when /dev/watchdog open fails
by Sasha Levin
From: "Shuah Khan (Samsung OSG)" <shuah(a)kernel.org>
[ Upstream commit 9a244229a4b850b11952a0df79607c69b18fd8df ]
When /dev/watchdog open fails, watchdog exits with "watchdog not enabled"
message. This is incorrect when open fails due to insufficient privilege.
Fix message to clearly state the reason when open fails with EACCESS when
a non-root user runs it.

[PATCH AUTOSEL 4.19 116/237] selftests/ftrace: Fix to test kprobe $comm arg only if available
by Sasha Levin
From: Masami Hiramatsu <mhiramat(a)kernel.org>
[ Upstream commit 2452c96e617a0ff6fb2692e55217a3fa57a7322c ]
Test $comm in kprobe-event argument syntax testcase
only if it is supported on the kernel because
$comm has been introduced 4.8 kernel.
So on older stable kernel, it should be skipped.

[PATCH AUTOSEL 4.19 096/237] selftests/bpf: fix return value comparison for tests in test_libbpf.sh
by Sasha Levin
From: Quentin Monnet <quentin.monnet(a)netronome.com>
[ Upstream commit c5fa5d602221362f8341ecd9e32d83194abf5bd9 ]
The return value for each test in test_libbpf.sh is compared with
if (( $? == 0 )) ; then ...
This works well with bash, but not with dash, that /bin/sh is aliased to
on some systems (such as Ubuntu).
Let's replace this comparison by something that works on both shells.

+=================
+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a script (``tools/testing/kunit/kunit.py``) that aids in building
+the Linux kernel as UML (`User Mode Linux
+<http://user-mode-linux.sourceforge.net/>`_), running KUnit tests, parsing
+the test results and displaying them in a user friendly manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all`
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all` --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

[PATCH v4] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
by Ilya Leoshkevich
Currently the following command produces an error message:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
The error message might not affect make return code, therefore one might
need to grep make output in order to detect it.
The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does
cd `dirname $TEST`
For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).
Fix by using $(addprefix) to prepend $(OUTPUT)/ to each member of
$(TEST_PROGS).
Fixes: 1a940687e424 ("selftests: lib.mk: copy test scripts and test files for make O=dir run")
Signed-off-by: Ilya Leoshkevich <iii(a)linux.ibm.com>
---
v1->v2:
- Append / to $(OUTPUT).
- Use $(addprefix) instead of $(foreach).
v2->v3:
- Split the patch in two.
- Improve the commit message.
v3->v4:
- Drop the first patch.
- Add a note regarding make return code to the commit message.

[PATCH linux-kselftest/test v1] Documentation: kunit: add documentation for kunit_tool
by Brendan Higgins
Add documentation for the Python script used to build, run, and collect
results from the kernel known as kunit_tool. kunit_tool
(tools/testing/kunit/kunit.py) was already added in previous commits.

+kunit_tool How-To
+=================
+
+What is kunit_tool?
+===================
+
+kunit_tool is a set of scripts that aid in building the Linux kernel as UML
+(`User Mode Linux <http://user-mode-linux.sourceforge.net/old/>`_), running
+KUnit tests, parsing the test results and displaying them in a user friendly
+manner.
+
+What is a kunitconfig?
+======================
+
+It's just a defconfig that kunit_tool looks for in the base directory.
+kunit_tool uses it to generate a .config as you might expect. In addition, it
+verifies that the generated .config contains the CONFIG options in the
+kunitconfig; the reason it does this is so that it is easy to be sure that a
+CONFIG that enables a test actually ends up in the .config.
+
+How do I use kunit_tool?
+=================================
+
+If a kunitconfig is present at the root directory, all you have to do is:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run
+
+However, you most likely want to use it with the following options:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=8
+
+- ``--timeout`` sets a maximum amount of time to allow tests to run.
+- ``--jobs`` sets the number of threads to use to build the kernel.
+
+If you just want to use the defconfig that ships with the kernel, you can
+append the ``--defconfig`` flag as well:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=8 --defconfig
+
+.. note::
+ This command is particularly helpful for getting started because it
+ just works. No kunitconfig needs to be present.
+
+For a list of all the flags supported by kunit_tool, you can run:
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run --help

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.
Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and
possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes
though stale NFS handles).

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH v4 00/23] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
OK, here we go. Any VFIO and Infiniband runtime testing from anyone, is
especially welcome here.
Changes since v3:
* VFIO fix (patch 8): applied further cleanup: removed a pre-existing,
unnecessary release and reacquire of mmap_sem. Moved the DAX vma
checks from the vfio call site, to gup internals, and added comments
(and commit log) to clarify.
* Due to the above, made a corresponding fix to the
pin_longterm_pages_remote(), which was actually calling the wrong
gup internal function.
* Changed put_user_page() comments, to refer to pin*() APIs, rather than
get_user_pages*() APIs.
* Reverted an accidental whitespace-only change in the IB ODP code.
* Added a few more reviewed-by tags.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-8: refactoring and preparatory cleanup, independent fixes
* Patch 9: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 10-15: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 16: Activate tracking of FOLL_PIN pages.
* Patches 17-19: convert FOLL_LONGTERM callers
* Patches: 20-22: gup_benchmark and run_vmtests support
* Patch 23: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v3 00/23] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
The cover letter is long, so the more important stuff is first:
* Jason, if you or someone could look at the the VFIO cleanup (patch 8)
and conversion to FOLL_PIN (patch 18), to make sure it's use of
remote and longterm gup matches what we discussed during the review
of v2, I'd appreciate it.
* Also for Jason and IB: as noted below, in patch 11, I am (too?) boldly
converting from put_user_pages() to release_pages().
* Jerome, I am going to take a look at doing your FOLL_GET change idea
(some callers should set FOLL_GET) separately, because it blew up "a
little bit" in my face. It's definitely a separate--tiny, but risky--project.
It also looks more reasonable when applied on top of this series here
(and it conflicts a lot), so I'm going to send it as a follow-up.
Changes since v2:
* Added a patch to convert IB/umem from normal gup, to gup_fast(). This
is also posted separately, in order to hopefully get some runtime
testing.
* Changed the page devmap code to be a little clearer,
thanks to Jerome for that.
* Split out the page devmap changes into a separate patch (and moved
Ira's Signed-off-by to that patch).
* Fixed my bug in IB: ODP code does not require pin_user_pages()
semantics. Therefore, revert the put_user_page() calls to put_page(),
and leave the get_user_pages() call as-is.
* As part of the revert, I am proposing here a change directly
from put_user_pages(), to release_pages(). I'd feel better if
someone agrees that this is the best way. It uses the more
efficient release_pages(), instead of put_page() in a loop,
and keep the change to just a few character on one line,
but OTOH it is not a pure revert.
* Loosened the FOLL_LONGTERM restrictions in the
__get_user_pages_locked() implementation, and used that in order
to fix up a VFIO bug. Thanks to Jason for that idea.
* Note the use of release_pages() in IB: is that OK?
* Added a few more WARN's and clarifying comments nearby.
* Many documentation improvements in various comments.
* Moved the new pin_user_pages.rst from Documentation/vm/ to
Documentation/core-api/ .
* Commit descriptions: added clarifying notes to the three patches
(drm/via, fs/io_uring, net/xdp) that already had put_user_page()
calls in place.
* Collected all pending Reviewed-by and Acked-by tags, from v1 and v2
email threads.
* Lot of churn from v2 --> v3, so it's possible that new bugs
sneaked in.
NOT DONE: separate patchset is required:
* __get_user_pages_locked(): stop compensating for
buggy callers who failed to set FOLL_GET. Instead, assert
that FOLL_GET is set (and fail if it's not).
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-8: refactoring and preparatory cleanup, independent fixes
* Patch 9: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 10-15: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 16: Activate tracking of FOLL_PIN pages.
* Patches 17-19: convert FOLL_LONGTERM callers
* Patches: 20-22: gup_benchmark and run_vmtests support
* Patch 23: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v4 2/2] pidfd: add tests for NSpid info in fdinfo
by Christian Kellner
From: Christian Kellner <christian(a)kellner.me>
Add a test that checks that if pid namespaces are configured the fdinfo
file of a pidfd contains an NSpid: entry containing the process id in
the current and additionally all nested namespaces. In the case that
a pidfd is from a pid namespace not in the same namespace hierarchy as
the process accessing the fdinfo file, ensure the 'NSpid' shows 0 for
that pidfd, analogous to the 'Pid' entry.
Signed-off-by: Christian Kellner <christian(a)kellner.me>
---
Changes in v4:
- Rework to test include a the situation where the fdinfo for a pidfd
of a process in a sibling pid namespace is being read and ensure
the NSpid field only contains one entry, being 0.

[PATCH AUTOSEL 4.19 193/209] selftests: forwarding: Have lldpad_app_wait_set() wait for unknown, too
by Sasha Levin
From: Petr Machata <petrm(a)mellanox.com>
[ Upstream commit 372809055f6c830ff978564e09f58bcb9e9b937c ]
Immediately after mlxsw module is probed and lldpad started, added APP
entries are briefly in "unknown" state before becoming "pending". That's
the state that lldpad_app_wait_set() typically sees, and since there are
no pending entries at that time, it bails out. However the entries have
not been pushed to the kernel yet at that point, and thus the test case
fails.
Fix by waiting for both unknown and pending entries to disappear before
proceeding.

rely on uAPI headers in the current kernel tree, rather than requiring the
correct version installed on the test system. While at it, group all
sections in a single binary and test the 'section' parameter.

[PATCH AUTOSEL 4.19 033/209] selftests/tls: Fix recv(MSG_PEEK) & splice() test cases
by Sasha Levin
From: Vakul Garg <vakul.garg(a)nxp.com>
[ Upstream commit 0ed3015c9964dab7a1693b3e40650f329c16691e ]
TLS test cases splice_from_pipe, send_and_splice &
recv_peek_multiple_records expect to receive a given nummber of bytes
and then compare them against the number of bytes which were sent.
Therefore, system call recv() must not return before receiving the
requested number of bytes, otherwise the subsequent memcmp() fails.
This patch passes MSG_WAITALL flag to recv() so that it does not return
prematurely before requested number of bytes are copied to receive
buffer.

[PATCH] kselftests: cgroup: Avoid the reuse of fd after it is deallocated
by Hewenliang
It is necessary to set fd to -1 when inotify_add_watch() fails in
cg_prepare_for_wait. Otherwise the fd which has been closed in
cg_prepare_for_wait may be misused in other functions such as
cg_enter_and_wait_for_frozen and cg_freeze_wait.
Fixes: 5313bfe425c8 ("selftests: cgroup: add freezer controller self-tests")

[PATCH v4] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root
v3:
- Removed unnecessary test case (everything set to 1)
- Correctly handle children without SIGCHLD
v4:
- Small cosmetic fixes
- Added two more tests with different sizes

[PATCH] selftests: Move kselftest_module.sh into kselftest/
by Kees Cook
The kselftest_module.sh file was not being installed by the Makefile
"install" target, rendering the lib/*.sh tests nonfunction. This fixes
that and takes the opportunity to move it into the kselftest/ subdirectory
which is where the kselftest infrastructure bits are collecting.

[PATCH v2 00/18] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
Changes since v1:
* Changed the function signature of __huge_pt_done() from int to void.
* Renamed __remove_refs_from_head() to put_compound_head().
* Improved the comment documentation in mm.h and gup.c
* Merged Documentation/vm/pin_user_pages.rst into the "introduce
FOLL_PIN" patch.
* Fixed Documentation/vm/pin_user_pages.rst:
* Fixed up a TODO about DAX.
* 31, not 32 bits total are available for counting
* Deleted some stale comments from the commit description of the
VFIO patch.
* Added Reviewed-by tags from Ira Weiny and Jens Axboe, and Acked-by
from Björn Töpel.
======================================================================
Original cover letter (edited to fix up the patch description numbers)
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-4: refactoring and preparatory cleanup, independent fixes
(Patch 4: V4L2-core bug fix (can be separately applied))
* Patch 5: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 6-11: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 12: Activate tracking of FOLL_PIN pages.
* Patches 13-15: convert FOLL_LONGTERM callers
* Patches: 16-17: gup_benchmark and run_vmtests support
* Patch 18: enforce FOLL_LONGTERM as a gup-internal (only) flag
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH v3 linux-kselftest-test 0/6] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch set as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 4.
Changes since v2:
- moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan)
(patch 1)
- split out non-exported interfaces in try-catch-impl.h (Brendan)
(patch 2)
- added kunit_find_symbol() and KUNIT_INIT_*SYMBOL to lookup non-exported
symbols. KUNIT_INIT_*SYMBOL() is defined so that a mismatch between
local symbol definition and definition of symbol in target will trigger
a compilation error when the object is compiled built-in (Brendan)
(patches 3, 4)
- removed #ifdef MODULE around module licenses (Randy, Brendan, Andy)
(patch 4)
- replaced kunit_test_suite() with kunit_test_suites() rather than
supporting both (Brendan) (patch 4)
- lookup sysctl_hung_task_timeout_secs as kunit may be built as a module
and the symbol may not be available (patch 5)
- fixed whitespace issues in doc (patch 6)
Alan Maguire (6):
kunit: move string-stream.h to lib/kunit/string-stream-impl.h
kunit: hide unexported try-catch interface in try-catch-impl.h
kunit: add kunit_find_symbol() function for symbol lookup
kunit: allow kunit tests to be loaded as a module
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH] selftests: bpf: add missing object file to TEST_FILES
by Anders Roxell
When installing kselftests to its own directory and run the
test_lwt_ip_encap.sh it will complain that test_lwt_ip_encap.o can't be
found. Same with the test_tc_edt.sh test it will complain that
test_tc_edt.o can't be found.

[PATCH v3] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root
v3:
- Removed unnecessary test case (everything set to 1)
- Correctly handle children without SIGCHLD

[PATCH 1/2] selftests: bpf: test_lwt_ip_encap: add missing object file to TEST_FILES
by Anders Roxell
When installing kselftests to its own directory and running the
test_lwt_ip_encap.sh it will complain that test_lwt_ip_encap.o can't be
find.
$ ./test_lwt_ip_encap.sh
starting egress IPv4 encap test
Error opening object test_lwt_ip_encap.o: No such file or directory
Object hashing failed!
Cannot initialize ELF context!
Failed to parse eBPF program: Invalid argument
Rework to add test_lwt_ip_encap.o to TEST_FILES so the object file gets
installed when installing kselftest.

[PATCH AUTOSEL 4.19 027/191] selftests/powerpc: Do not fail with reschedule
by Sasha Levin
From: Breno Leitao <leitao(a)debian.org>
[ Upstream commit 44d947eff19d64384efc06069509db7a0a1103b0 ]
There are cases where the test is not expecting to have the transaction
aborted, but, the test process might have been rescheduled, either in the
OS level or by KVM (if it is running on a KVM guest machine). The process
reschedule will cause a treclaim/recheckpoint which will cause the
transaction to doom, aborting the transaction as soon as the process is
rescheduled back to the CPU. This might cause the test to fail, but this is
not a failure in essence.
If that is the case, TEXASR[FC] is indicated with either
TM_CAUSE_RESCHEDULE or TM_CAUSE_KVM_RESCHEDULE for KVM interruptions.
In this scenario, ignore these two failures and avoid the whole test to
return failure.

[PATCH 1/2] memfd: Fix COW issue on MAP_PRIVATE and F_SEAL_FUTURE_WRITE mappings
by Joel Fernandes (Google)
From: Nicolas Geoffray <ngeoffray(a)google.com>
F_SEAL_FUTURE_WRITE has unexpected behavior when used with MAP_PRIVATE:
A private mapping created after the memfd file that gets sealed with
F_SEAL_FUTURE_WRITE loses the copy-on-write at fork behavior, meaning
children and parent share the same memory, even though the mapping is
private.
The reason for this is due to the code below:
static int shmem_mmap(struct file *file, struct vm_area_struct *vma)
{
struct shmem_inode_info *info = SHMEM_I(file_inode(file));
if (info->seals & F_SEAL_FUTURE_WRITE) {
/*
* New PROT_WRITE and MAP_SHARED mmaps are not allowed when
* "future write" seal active.
*/
if ((vma->vm_flags & VM_SHARED) && (vma->vm_flags & VM_WRITE))
return -EPERM;
/*
* Since the F_SEAL_FUTURE_WRITE seals allow for a MAP_SHARED
* read-only mapping, take care to not allow mprotect to revert
* protections.
*/
vma->vm_flags &= ~(VM_MAYWRITE);
}
...
}
And for the mm to know if a mapping is copy-on-write:
static inline bool is_cow_mapping(vm_flags_t flags)
{
return (flags & (VM_SHARED | VM_MAYWRITE)) == VM_MAYWRITE;
}
The patch fixes the issue by making the mprotect revert protection
happen only for shared mappings. For private mappings, using mprotect
will have no effect on the seal behavior.

[PATCH v10 00/12] Add arm64/signal initial kselftest support
by Cristian Marussi
Hi
this patchset aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
This series is based on v5.4-rc4.
A common internal test-case layout is proposed for signal tests and it is
wired-up to the toplevel kselftest Makefile, so that it should be possible
at the end to run it on an arm64 target in the usual way with KSFT.
~/linux# make TARGETS=arm64 kselftest
New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped
by family inside subdirectories: arm64/signal is the first family proposed
with this series.
This series converts also to this subdirectory scheme the pre-existing
KSFT arm64 tags tests (already merged in v5.3), moving them into their own
arm64/tags subdirectory.
Thanks
Cristian

- further details in the included READMEs
- more tests still to be written (current strategy is going through the
related Kernel signal-handling code and write a test for each possible
and sensible code-path)
A few ideas for more TODO testcases:
- mangle_pstate_invalid_ssbs_regs: mess with SSBS bits on every
possible configured behavior
- fake_sigreturn_unmapped_sp: SP into unmapped addrs
- fake_sigreturn_kernelspace_sp: SP into kernel addrs
- fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed
- fake_sigreturn_misaligned_sp_4: misaligned SP by 4
(i.e., __alignof__(struct _aarch64_ctx))
- fake_sigreturn_misaligned_sp_8: misaligned SP by 8
(i.e., sizeof(struct _aarch64_ctx))
- fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow
__reserved[], but is not a multiple of 16
- fake_sigreturn_bad_size_tiny: a size that is less than 16
- fake_sigreturn_bad_size_overflow_tiny: a size that does overflow
__reserved[], but by less than 16 bytes?
- mangle_sve_invalid_extra_context: SVE extra_context invalid
- SVE signal testcases and special handling will be part of an additional
patch still to be released
- KSFT arm64 tags test patch
https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300…
is relocated into its own directory under tools/testing/selftests/arm64/tags
Changes:
--------
v9 --> v10:
- rebased on v5.4-rc4
- removed some test_init stale code related to PAN/UAO
(not used nor needed and wrong)
v8-->v9:
- fixed a couple of misplaced .gitignore
v7-->v8:
- removed SSBS test case
- split remnants of SSBS patch (v7 05/11), containing some helpers,
into two distinct patches
v6-->v7:
- rebased on v5.4-rc2
- renamed SUBTARGETS arm64/ toplevel Makefile ENV to ARM64_SUBTARGETS
- fixed fake_sigreturn alignment routines (off by one)
- fixed SSBS test: avoid using MRS/MSR as whole and SKIP when SSBS not
supported
- reporting KSFT_SKIP when needed (usually if test_init(0 fails)
- using ID_AA64PFR1_EL1.SSBS to check SSBS support instead of HWCAP_SSBS
v5-->v6:
- added arm64 toplevel Makefile SUBTARGETS env var to be able to selectively
build only some arm64/ tests subdirectories
- removed unneed toplevel Makefile exports and fixed Copyright
- better checks for supported features and features names helpers
- converted some run-time critical assert() to abort() to avoid
issues when -NDEBUG is set
- default_handler() signal handler refactored and split
- using SIGTRAP for get_current_context()
- use volatile where proper
- refactor and relocate test_init() invocation
- review usage of MRS SSBS instructions depending on HW_SSBS
- cleanup fake_sigreturn trampoline
- cleanup get_starting_header helper
- avoiding timeout test failures wherever possible (fail immediately
if possible)
v4-->v5:
- rebased on arm64/for-next-core merging 01/11 with KSFT tags tests:
commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel")
- moved .gitignore up on elevel
- moved kernel header search mechanism into KSFT arm64 toplevel Makefile
so that it can be used easily also by each arm64 KSFT subsystem inside
subdirs of arm64
v3-->v4:
- rebased on v5.3-rc6
- added test descriptions
- fixed commit messages (imperative mood)
- added missing includes and removed unneeded ones
- added/used new get_starting_head() helper
- fixed/simplified signal.S::fakke_sigreturn()
- added set_regval() macro and .init initialization func
- better synchonization in get_current_context()
- macroization of mangle_pstate_invalid_mode_el
- split mangle_pstate_invalid_mode_el h/t
- removed standalone mode
- simplified CPU features checks
- fixed/refactored get_header() and validation routines
- simplfied docs
v2-->v3:
- rebased on v5.3-rc2
- better test result characterization looking for
SEGV_ACCERR in si_code on SIGSEGV
- using KSFT Framework macros for retvalues
- removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused
- reviewed generation process of test_arm64_signals.sh runner script
- re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly
extended fake_sigreturn() helper
- added tests' TODO notes
v1-->v2:
- rebased on 5.2-rc7
- various makefile's cleanups
- mixed READMEs fixes
- fixed test_arm64_signals.sh runner script
- cleaned up assembly code in signal.S
- improved get_current_context() logic
- fixed SAFE_WRITE()
- common support code split into more chunks, each one introduced when
needed by some new testcases
- fixed some headers validation routines in testcases.c
- removed some still broken/immature tests:
+ fake_sigreturn_misaligned
+ fake_sigreturn_overflow_reserved
+ mangle_pc_invalid
+ mangle_sp_misaligned
- fixed some other testcases:
+ mangle_pstate_ssbs_regs: better checks of SSBS bit when feature unsupported
+ mangle_pstate_invalid_compat_toggle: name fix
+ mangle_pstate_invalid_mode_el[1-3]: precautionary zeroing PSTATE.MODE
+ fake_sigreturn_bad_magic, fake_sigreturn_bad_size,
fake_sigreturn_bad_size_for_magic0:
- accounting for available space...dropping extra when needed
- keeping alignent
- new testcases on FPSMID context:
+ fake_sigreturn_missing_fpsimd
+ fake_sigreturn_duplicated_fpsimd

[PATCH RESEND v3 0/2] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
by Ilya Leoshkevich
Hello,
Is there anything blocking this from getting merged?
This patch series fixes the following problem:
linux# make kselftest TARGETS=bpf O=/mnt/linux-build
# selftests: bpf: test_libbpf.sh
# ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
# test_libbpf: failed at file test_l4lb.o
# selftests: test_libbpf [FAILED]
Patch 1 appends / to $(OUTPUT) in order to make it more uniform with the
rest of the tree.
Patch 2 fixes the problem by prepending $(OUTPUT) to all members of
$(TEST_PROGS).
v1->v2:
- Append / to $(OUTPUT).
- Use $(addprefix) instead of $(foreach).
v2->v3:
- Split the patch in two.
- Improve the commit message.
Ilya Leoshkevich (2):
selftests: append / to $(OUTPUT)
selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

[PATCH v2] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

v2:
- Applied Christian's suggestions
- Skip root-only tests when running as non-root

[PATCH] selftests/livepatch: filter 'taints' from dmesg comparison
by Joe Lawrence
The livepatch selftests compare expected dmesg output to verify kernel
behavior. They currently filter out "tainting kernel with
TAINT_LIVEPATCH" messages which may be logged when loading livepatch
modules.
Further filter the log to also drop "loading out-of-tree module taints
kernel" messages in case the klp_test modules have been build without
the in-tree module flag.
Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com>
---
Note: I stumbled across this in a testing scenario and thought it might
be generally useful to extend this admittedly fragile mechanism. Since
there are no related livepatch-core changes, this can go through Shuah's
kselftest tree if she prefers. -- Joe

[PATCH net-next v2] selftest: net: add some traceroute tests
by fruggeri＠arista.com
Added the following traceroute tests.
IPV6:
Verify that in this scenario
------------------------ N2
| |
------ ------ N3 ----
| R1 | | R2 |------|H2|
------ ------ ----
| |
------------------------ N1
|
----
|H1|
----
where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.
IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario
1.0.3.1/24
---- 1.0.1.3/24 1.0.1.1/24 ---- 1.0.2.1/24 1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
---- N1 ---- N2 ----
where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.
v2: fixed some typos, and have bridge in R1 instead of R2 in IPV6 test.

[PATCH linux-kselftest/test v1] apparmor: add AppArmor KUnit tests for policy unpack
by Brendan Higgins
From: Mike Salvatore <mike.salvatore(a)canonical.com>
Add KUnit tests to test AppArmor unpacking of userspace policies.
AppArmor uses a serialized binary format for loading policies. To find
policy format documentation see
Documentation/admin-guide/LSM/apparmor.rst.
In order to write the tests against the policy unpacking code, some
static functions needed to be exposed for testing purposes. One of the
goals of this patch is to establish a pattern for which testing these
kinds of functions should be done in the future.

Sorry in advanced for emailing so many people. I suspect that there are
quite a few people who will be interested in this discussion - not so
much because of the AppArmor test itself - but because I think this
patch offers a good place to discuss how we should/will need to handle
code visibility for the purpose of writing tests.
I fully expect there to be a great deal of discussion on this patch
especially on the topic of visibility and how to expose symbols for
testing. Based on conversations I had before sending this patch out, I
expect to see a number of different suggestions on how to test symbols
that are not normally exposed.

[PATCH net-next] selftest: net: add some traceroute tests
by fruggeri＠arista.com
Added the following traceroute tests.
IPV6:
Verify that in this scenario
------------------------ N2
| |
------ ------ N3 ----
| R1 | | R2 |------|H2|
------ ------ ----
| |
------------------------ N1
|
----
|H1|
----
where H1's default route goes through R1 and R1's default route goes
through R2 over N2, traceroute6 from H1 to H2 reports R2's address
on N2 and not N1.
IPV4:
Verify that traceroute from H1 to H2 shows 1.0.1.1 in this scenario
1.0.3.1/24
---- 1.0.1.3/24 1.0.1.1/24 ---- 1.0.2.1/24 1.0.2.4/24 ----
|H1|--------------------------|R1|--------------------------|H2|
---- N1 ---- N2 ----
where net.ipv4.icmp_errors_use_inbound_ifaddr is set on R1 and
1.0.3.1/24 and 1.0.1.1/24 are respectively R1's primary and secondary
address on N1.

[PATCH 00/19] mm/gup: track dma-pinned pages: FOLL_PIN, FOLL_LONGTERM
by John Hubbard
Hi,
This applies cleanly to linux-next and mmotm, and also to linux.git if
linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB
case") is first applied there.
This provides tracking of dma-pinned pages. This is a prerequisite to
solving the larger problem of proper interactions between file-backed
pages, and [R]DMA activities, as discussed in [1], [2], [3], and in
a remarkable number of email threads since about 2017. :)
A new internal gup flag, FOLL_PIN is introduced, and thoroughly
documented in the last patch's Documentation/vm/pin_user_pages.rst.
I believe that this will provide a good starting point for doing the
layout lease work that Ira Weiny has been working on. That's because
these new wrapper functions provide a clean, constrained, systematically
named set of functionality that, again, is required in order to even
know if a page is "dma-pinned".
In contrast to earlier approaches, the page tracking can be
incrementally applied to the kernel call sites that, until now, have
been simply calling get_user_pages() ("gup"). In other words, opt-in by
changing from this:
get_user_pages() (sets FOLL_GET)
put_page()
to this:
pin_user_pages() (sets FOLL_PIN)
put_user_page()
Because there are interdependencies with FOLL_LONGTERM, a similar
conversion as for FOLL_PIN, was applied. The change was from this:
get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET)
put_page()
to this:
pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM)
put_user_page()
============================================================
Patch summary:
* Patches 1-4: refactoring and preparatory cleanup, independent fixes
(Patch 4: V4L2-core bug fix (can be separately applied))
* Patch 5: introduce pin_user_pages(), FOLL_PIN, but no functional
changes yet
* Patches 6-11: Convert existing put_user_page() callers, to use the
new pin*()
* Patch 12: Activate tracking of FOLL_PIN pages.
* Patches 13-15: convert FOLL_LONGTERM callers
* Patches: 16-17: gup_benchmark and run_vmtests support
* Patch 18: enforce FOLL_LONGTERM as a gup-internal (only) flag
* Patch 19: Documentation/vm/pin_user_pages.rst
============================================================
Testing:
* I've done some overall kernel testing (LTP, and a few other goodies),
and some directed testing to exercise some of the changes. And as you
can see, gup_benchmark is enhanced to exercise this. Basically, I've been
able to runtime test the core get_user_pages() and pin_user_pages() and
related routines, but not so much on several of the call sites--but those
are generally just a couple of lines changed, each.
Not much of the kernel is actually using this, which on one hand
reduces risk quite a lot. But on the other hand, testing coverage
is low. So I'd love it if, in particular, the Infiniband and PowerPC
folks could do a smoke test of this series for me.
Also, my runtime testing for the call sites so far is very weak:
* io_uring: Some directed tests from liburing exercise this, and they pass.
* process_vm_access.c: A small directed test passes.
* gup_benchmark: the enhanced version hits the new gup.c code, and passes.
* infiniband (still only have crude "IB pingpong" working, on a
good day: it's not exercising my conversions at runtime...)
* VFIO: compiles (I'm vowing to set up a run time test soon, but it's
not ready just yet)
* powerpc: it compiles...
* drm/via: compiles...
* goldfish: compiles...
* net/xdp: compiles...
* media/v4l2: compiles...
============================================================
Next:
* Get the block/bio_vec sites converted to use pin_user_pages().
* Work with Ira and Dave Chinner to weave this together with the
layout lease stuff.

[PATCH linux-kselftest/test v6] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).

Question about where to put test drivers
by Ralph Campbell
I'm planning to add some kernel self tests which use a user level program
in tools/testing/selftests/vm/ and a kernel module. See:
https://lore.kernel.org/linux-mm/20191023195515.13168-1-rcampbell@nvidia.co…
The question is where to put the kernel module source code.
I see some test modules that are in lib/test_*.ko and my patch
initially placed the hmm-dmirror module in drivers/char/ since
it creates a character device.
Any advice?

[PATCH v7 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter
by Mina Almasry
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.
Problem:
Currently tasks attempting to allocate more hugetlb memory than is available get
a failure at mmap/shmget time. This is thanks to Hugetlbfs Reservations [1].
However, if a task attempts to allocate hugetlb memory only more than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call,
but will SIGBUS the task when it attempts to fault the memory in.
We have developers interested in using hugetlb_cgroups, and they have expressed
dissatisfaction regarding this behavior. We'd like to improve this
behavior such that tasks violating the hugetlb_cgroup limits get an error on
mmap/shmget time, rather than getting SIGBUS'd when they try to fault
the excess memory in.
The underlying problem is that today's hugetlb_cgroup accounting happens
at hugetlb memory *fault* time, rather than at *reservation* time.
Thus, enforcing the hugetlb_cgroup limit only happens at fault time, and
the offending task gets SIGBUS'd.
Proposed Solution:
A new page counter named hugetlb.xMB.reservation_[limit|usage]_in_bytes. This
counter has slightly different semantics than
hugetlb.xMB.[limit|usage]_in_bytes:
- While usage_in_bytes tracks all *faulted* hugetlb memory,
reservation_usage_in_bytes tracks all *reserved* hugetlb memory and
hugetlb memory faulted in without a prior reservation.
- If a task attempts to reserve more memory than limit_in_bytes allows,
the kernel will allow it to do so. But if a task attempts to reserve
more memory than reservation_limit_in_bytes, the kernel will fail this
reservation.
This proposal is implemented in this patch series, with tests to verify
functionality and show the usage. We also added cgroup-v2 support to
hugetlb_cgroup so that the new use cases can be extended to v2.
Alternatives considered:
1. A new cgroup, instead of only a new page_counter attached to
the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code
duplication with hugetlb_cgroup. Keeping hugetlb related page counters under
hugetlb_cgroup seemed cleaner as well.
2. Instead of adding a new counter, we considered adding a sysctl that modifies
the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at
reservation time rather than fault time. Adding a new page_counter seems
better as userspace could, if it wants, choose to enforce different cgroups
differently: one via limit_in_bytes, and another via
reservation_limit_in_bytes. This could be very useful if you're
transitioning how hugetlb memory is partitioned on your system one
cgroup at a time, for example. Also, someone may find usage for both
limit_in_bytes and reservation_limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- libhugetlbfs tests mostly passing, but some tests have trouble with and

[BUGFIX PATCH] selftests: breakpoints: Fix a typo of function name
by Masami Hiramatsu
Since commit 5821ba969511 ("selftests: Add test plan API to kselftest.h
and adjust callers") accidentally introduced 'a' typo in the front of
run_test() function, breakpoint_test_arm64.c became not able to be
compiled.
Remove the 'a' from arun_test().
Fixes: 5821ba969511 ("selftests: Add test plan API to kselftest.h and adjust callers")

[PATCH v2] kernel-doc: rename the kernel-doc directive 'functions' to 'identifiers'
by Changbin Du
The 'functions' directive is not only for functions, but also works for
structs/unions. So the name is misleading. This patch renames it to
'identifiers', which specific the functions/types to be included in
documentation. We keep the old name as an alias of the new one before
all documentation are updated.

[PATCH] selftests: add tests for clone3()
by Adrian Reber
This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.

[BUGFIX PATCH v3 0/5] selftests: Fixes for 32bit arch
by Masami Hiramatsu
Hi,
Here are the 3rd version of kselftest fixes some on 32bit arch
(e.g. arm)
In this version, I updated [1/5] to make va_max 1MB unconditionally
according to Alexey's comment.
When I built the ksefltest on arm, I hit some 32bit related warnings.
Here are the patches to fix those issues.
- [1/5] va_max was set 2^32 even on 32bit arch. This can make
va_max == 0 and always fail. Make it 1GB unconditionally.
- [2/5] Some VM tests requires 64bit user space, which should
not run on 32bit arch.
- [3/5] For counting the size of large file, we should use
size_t instead of unsinged long.
- [4/5] Gcc warns printf format for size_t and int64_t on
32bit arch. Use %llu and cast it.
- [5/5] Gcc warns __u64 and pointer type castings. It should
once translated to unsigned long.
Thank you,
---

[PATCH] selftests: gen_kselftest_tar.sh: Do not clobber kselftest/
by Kees Cook
The default installation location for gen_kselftest_tar.sh was still
"kselftest/" which collides with the existing directory. Instead, this
moves the installation target into "kselftest_install/kselftest/" and
adjusts the tar creation accordingly. This also adjusts indentation and
logic to be consistent.
Fixes: 42d46e57ec97 ("selftests: Extract single-test shell logic from lib.mk")

[PATCH v4 0/6] lib/string: Add strscpy_pad() function
by Tobin C. Harding
Hi Shua,
Here is the set with cleanup as suggested by Kees on v3.
Configured, built, and tested all modules loaded by
tools/testing/selftests/lib/*.sh
>From previous cover letters ...
While doing the testing for strscpy_pad() it was noticed that there is
duplication in how test modules are being fed to kselftest and also in
the test modules themselves.
This set makes an attempt at adding a framework to kselftest for writing
kernel test modules. It also adds a script for use in creating script
test runners for kselftest. My macro-foo is not great, all criticism
and suggestions very much appreciated. The design is based on test
modules lib/test_printf.c, lib/test_bitmap.c, lib/test_xarray.c.
Changes since last version:
- Remove dependency on Bash (thanks Kees)
- Use oneliner to implement kselftest test runners (thanks Kees)
- Squash patch that adds kselftest script creator script with patch
that uses it.
- Fix typos (thanks Randy)
- Add Kees' Acked-by tags to all patches
thanks,
Tobin.
Tobin C. Harding (6):
lib/test_printf: Add empty module_exit function
kselftest: Add test runner creation script
kselftest: Add test module framework header
lib: Use new kselftest header
lib/string: Add strscpy_pad() function
lib: Add test module for strscpy_pad

[PATCH linux-kselftest/test v7] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).

---
This revision, v7, renames tests with 'for_each' in their name to have
'for__each' instead. This works around the checkpatch.pl bug Shuah
mentioned, as checkpatch.pl believes that function definitions with
'for_each' in the name are actually loops, and wants the '{' on the
previous line.
With this change, checkpatch is perfectly happy.

[PATCH v1] selftest/trustedkeys: TPM 1.2 trusted keys test
by Mimi Zohar
Create, save and load trusted keys test
Signed-off-by: Mimi Zohar <zohar(a)linux.ibm.com>
Change log v1:
- Replace the directions for using Trousers to take ownership of the TPM
with directions for using the IBM TSS.
- Differentiate between different types of errors. Recent bug is causing
"add_key: Timer expired".

[PATCH v23 14/24] selftests/x86: Add a selftest for SGX
by Jarkko Sakkinen
Add a selftest for SGX. It is a trivial test where a simple enclave
copies one 64-bit word of memory between two memory locations given to
the enclave as arguments. Use ENCLS[EENTER] to invoke the enclave.

[PATCH RESEND v14 0/6] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v14: [<https://lore.kernel.org/lkml/20191010054140.8483-1-cyphar@cyphar.com/>]
* The magic-link changes (and O_EMPTYPATH) have been dropped from this series
-- they will be developed and sent separately. The main reason is that we
need to restrict things other than open(2) (examples include truncate(2) as
well as mount(MS_BIND)). This will require a fair amount of extra work, and
there's no point stalling openat2(2) for that work to be completed.
* Minor rework of 'struct open_how':
* To avoid future headaches, make it a non-const argument.
* Expand ->flags and ->resolve to 64-bit fields to allow for more flag
extensions without needing to add separate fields too early. This
requires adding a bit of explicit padding (32 bits) to avoid userspace
putting garbage in the alignment padding -- this can be repurposed for
future extensions.
* upgrade_mask is dropped (and will be a separate field when we add it
again in the future) to avoid userspace foot-guns.
* Expand -EINVAL checks in build_open_flags(). Rather than silently
ignoring silly flag combinations (such as O_TMPFILE|O_PATH or
O_PATH|<most flags>), give an -EINVAL. All of the silent ignore semantics
were added to open(2) because we couldn't return -EINVAL -- but we can
now!
* open(2) and openat(2) clean up their flags before passing them to
build_open_flags(), so all mixed flags will continue to work. There is
one exception which is (O_PATH|O_TMPFILE) -- this is no longer
permitted (as far as I can tell this appears to be a bug, and there are
no userspace users that I've hit after running this code for a few
days). If it turns out that userspace does depend on (O_PATH|O_TMPFILE)
working, we can only disallow it for openat2(2).
* Don't zero out nd->root in complete_walk() for RCU-walk if we're doing a
scoped-lookup (this prevents a needless REF-walk retry).
* Attempt all tests on kernels that don't have openat2(2), rather than just
skipping everything.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the direc-
tory referred to by the file descriptor dirfd (or the current working directory of the
calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute, then
dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname is
resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not con-
tain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see path_resolu-
tion(7) for background information.) The primary use case for these flags
is to allow trusted programs to restrict how untrusted paths (or paths in-
side untrusted directories) are resolved. The full list of resolve flags is
given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as bind mounts are
very widely used by end-users. Setting this flag indiscrimnately for
all uses of openat2() may result in spurious errors on previously-
functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable (un-
less it is used for a specific security purpose), as symbolic links
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on previ-
ously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly open-
ing these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of path-
name) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute sym-
bolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root perma-
nently for a process), RESOLVE_IN_ROOT allows a program to effi-
ciently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are han-
dled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or poten-
tial attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new ex-
tension fields will always be appended, the size will always increase.) This extensibil-
ity design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel sup-
ports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-compatibil-
ity.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all ex-
tensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported ex-
tension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of exten-
sions. However, if a userspace program wishes to determine what extensions the running
kernel supports, they may conduct a binary search on size (to find the largest value which
doesn't produce an error of E2BIG.)

[PATCH AUTOSEL 5.3 96/99] mm/gup_benchmark: add a missing "w" to getopt string
by Sasha Levin
From: John Hubbard <jhubbard(a)nvidia.com>
[ Upstream commit 6f24c8d30d08f270b54f4c2cb9b08dfccbe59c57 ]
Even though gup_benchmark.c has code to handle the -w command-line option,
the "w" is not part of the getopt string. It looks as if it has been
missing the whole time.
On my machine, this leads naturally to the following predictable result:
$ sudo ./gup_benchmark -w
./gup_benchmark: invalid option -- 'w'
...which is fixed with this commit.

Many distributions enable rp_filter. However, the flow dissector test
generates packets that have 1.1.1.1 set as (inner) source address without
this address being reachable. This causes the selftest to fail.

Linux-5.4: bpf: test_core_reloc_arrays.o: Segmentation fault with llc -march=bpf
by Prabhakar Kushwaha
Adding other mailing list, folks...
Hi All,
I am trying to build kselftest on Linux-5.4 on ubuntu 18.04. I installed
LLVM-9.0.0 and Clang-9.0.0 from below links after following steps from
[1] because of discussion [2]
https://releases.llvm.org/9.0.0/llvm-9.0.0.src.tar.xz
https://releases.llvm.org/9.0.0/clang-tools-extra-9.0.0.src.tar.xz
https://releases.llvm.org/9.0.0/cfe-9.0.0.src.tar.xz
Now, i am trying with llc -march=bpf, with this segmentation fault is

To add more details,
Commenting following lines in bpf/progs/test_core_reloc_arrays.c
removes the segmentation fault.

It looks to be something related llc and more than 1 dimension array.
has anyone faced such error.
Please suggest!!

kthread: make __kthread_queue_delayed_work static
The __kthread_queue_delayed_work is not exported so
make it static, to avoid the following sparse warning:
kernel/kthread.c:869:6: warning: symbol
'__kthread_queue_delayed_work' was not declared. Should it be static?

[PATCH] selftests/livepatch: Disable the timeout
by Miroslav Benes
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") introduced a timeout per test. Livepatch tests could
run longer than 45 seconds, especially on slower machines. They do not
hang and they detect if something goes awry with internal accounting.
Better than looking for an arbitrary value, just disable the timeout for
livepatch selftests.

[PATCH AUTOSEL 4.19 04/37] rseq/selftests: x86: Work-around bogus gcc-8 optimisation
by Sasha Levin
From: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com>
[ Upstream commit fe22983d92c15253ea8eb854acbe863fc2313759 ]
gcc-8 version 8.1.0, 8.2.0, and 8.3.0 generate broken assembler with asm
goto that have a thread-local storage "m" input operand on both x86-32
and x86-64. For instance:
__thread int var;
static int fct(void)
{
asm goto ( "jmp %l[testlabel]\n\t"
: : [var] "m" (var) : : testlabel);
return 0;
testlabel:
return 1;
}
int main()
{
return fct();
}
% gcc-8 -O2 -o test-asm-goto test-asm-goto.c
/tmp/ccAdHJbe.o: In function `main':
test-asm-goto.c:(.text.startup+0x1): undefined reference to `.L2'
collect2: error: ld returned 1 exit status
% gcc-8 -m32 -O2 -o test-asm-goto test-asm-goto.c
/tmp/ccREsVXA.o: In function `main':
test-asm-goto.c:(.text.startup+0x1): undefined reference to `.L2'
collect2: error: ld returned 1 exit status
Work-around this compiler bug in the rseq-x86.h header by passing the
address of the __rseq_abi TLS as a register operand rather than using
the "m" input operand.

[REVIEW PATCH v5 3/3] tests: add close_range() tests
by Christian Brauner
This adds basic tests for the new close_range() syscall.
- test that no invalid flags can be passed
- test that a range of file descriptors is correctly closed
- test that a range of file descriptors is correctly closed if there there
are already closed file descriptors in the range
- test that max_fd is correctly capped to the current fdtable maximum

[PATCH v9 00/12] Add arm64/signal initial kselftest support
by Cristian Marussi
Hi
this patchset aims to add the initial arch-specific arm64 support to
kselftest starting with signals-related test-cases.
This series is based on v5.4-rc2.
A common internal test-case layout is proposed for signal tests and it is
wired-up to the toplevel kselftest Makefile, so that it should be possible
at the end to run it on an arm64 target in the usual way with KSFT.
~/linux# make TARGETS=arm64 kselftest
New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped
by family inside subdirectories: arm64/signal is the first family proposed
with this series.
This series converts also to this subdirectory scheme the pre-existing
KSFT arm64 tags tests (already merged in v5.3), moving them into their own
arm64/tags subdirectory.
Thanks
Cristian
Notes:
-----
- further details in the included READMEs
- more tests still to be written (current strategy is going through the
related Kernel signal-handling code and write a test for each possible
and sensible code-path)
A few ideas for more TODO testcases:
- mangle_pstate_invalid_ssbs_regs: mess with SSBS bits on every
possible configured behavior
- fake_sigreturn_unmapped_sp: SP into unmapped addrs
- fake_sigreturn_kernelspace_sp: SP into kernel addrs
- fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed
- fake_sigreturn_misaligned_sp_4: misaligned SP by 4
(i.e., __alignof__(struct _aarch64_ctx))
- fake_sigreturn_misaligned_sp_8: misaligned SP by 8
(i.e., sizeof(struct _aarch64_ctx))
- fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow
__reserved[], but is not a multiple of 16
- fake_sigreturn_bad_size_tiny: a size that is less than 16
- fake_sigreturn_bad_size_overflow_tiny: a size that does overflow
__reserved[], but by less than 16 bytes?
- mangle_sve_invalid_extra_context: SVE extra_context invalid
- SVE signal testcases and special handling will be part of an additional patch
still to be released
- KSFT arm64 tags test patch
https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300…
is relocated into its own directory under tools/testing/selftests/arm64/tags
Changes:
--------
v8-->v9:
- fixed a couple of misplaced .gitignore
v7-->v8:
- removed SSBS test case
- split remnants of SSBS patch (v7 05/11), containing some helpers,
into two distinct patches
v6-->v7:
- rebased on v5.4-rc2
- renamed SUBTARGETS arm64/ toplevel Makefile ENV to ARM64_SUBTARGETS
- fixed fake_sigreturn alignment routines (off by one)
- fixed SSBS test: avoid using MRS/MSR as whole and SKIP when SSBS not
supported
- reporting KSFT_SKIP when needed (usually if test_init(0 fails)
- using ID_AA64PFR1_EL1.SSBS to check SSBS support instead of HWCAP_SSBS
v5-->v6:
- added arm64 toplevel Makefile SUBTARGETS env var to be able to selectively
build only some arm64/ tests subdirectories
- removed unneed toplevel Makefile exports and fixed Copyright
- better checks for supported features and features names helpers
- converted some run-time critical assert() to abort() to avoid
issues when -NDEBUG is set
- default_handler() signal handler refactored and split
- using SIGTRAP for get_current_context()
- use volatile where proper
- refactor and relocate test_init() invocation
- review usage of MRS SSBS instructions depending on HW_SSBS
- cleanup fake_sigreturn trampoline
- cleanup get_starting_header helper
- avoiding timeout test failures wherever possible (fail immediately
if possible)
v4-->v5:
- rebased on arm64/for-next-core merging 01/11 with KSFT tags tests:
commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel")
- moved .gitignore up on elevel
- moved kernel header search mechanism into KSFT arm64 toplevel Makefile
so that it can be used easily also by each arm64 KSFT subsystem inside
subdirs of arm64
v3-->v4:
- rebased on v5.3-rc6
- added test descriptions
- fixed commit messages (imperative mood)
- added missing includes and removed unneeded ones
- added/used new get_starting_head() helper
- fixed/simplified signal.S::fakke_sigreturn()
- added set_regval() macro and .init initialization func
- better synchonization in get_current_context()
- macroization of mangle_pstate_invalid_mode_el
- split mangle_pstate_invalid_mode_el h/t
- removed standalone mode
- simplified CPU features checks
- fixed/refactored get_header() and validation routines
- simplfied docs
v2-->v3:
- rebased on v5.3-rc2
- better test result characterization looking for
SEGV_ACCERR in si_code on SIGSEGV
- using KSFT Framework macros for retvalues
- removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused
- reviewed generation process of test_arm64_signals.sh runner script
- re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly
extended fake_sigreturn() helper
- added tests' TODO notes
v1-->v2:
- rebased on 5.2-rc7
- various makefile's cleanups
- mixed READMEs fixes
- fixed test_arm64_signals.sh runner script
- cleaned up assembly code in signal.S
- improved get_current_context() logic
- fixed SAFE_WRITE()
- common support code split into more chunks, each one introduced when
needed by some new testcases
- fixed some headers validation routines in testcases.c
- removed some still broken/immature tests:
+ fake_sigreturn_misaligned
+ fake_sigreturn_overflow_reserved
+ mangle_pc_invalid
+ mangle_sp_misaligned
- fixed some other testcases:
+ mangle_pstate_ssbs_regs: better checks of SSBS bit when feature unsupported
+ mangle_pstate_invalid_compat_toggle: name fix
+ mangle_pstate_invalid_mode_el[1-3]: precautionary zeroing PSTATE.MODE
+ fake_sigreturn_bad_magic, fake_sigreturn_bad_size,
fake_sigreturn_bad_size_for_magic0:
- accounting for available space...dropping extra when needed
- keeping alignent
- new testcases on FPSMID context:
+ fake_sigreturn_missing_fpsimd
+ fake_sigreturn_duplicated_fpsimd

[PATCH v14 0/6] open: introduce openat2(2) syscall
by Aleksa Sarai
This patchset is being developed here:
<https://github.com/cyphar/linux/tree/openat2/master>
Patch changelog:
v14:
* The magic-link changes (and O_EMPTYPATH) have been dropped from this series
-- they will be developed and sent separately. The main reason is that we
need to restrict things other than open(2) (examples include truncate(2) as
well as mount(MS_BIND)). This will require a fair amount of extra work, and
there's no point stalling openat2(2) for that work to be completed.
* Minor rework of 'struct open_how':
* To avoid future headaches, make it a non-const argument.
* Expand ->flags and ->resolve to 64-bit fields to allow for more flag
extensions without needing to add separate fields too early. This
requires adding a bit of explicit padding (32 bits) to avoid userspace
putting garbage in the alignment padding -- this can be repurposed for
future extensions.
* upgrade_mask is dropped (and will be a separate field when we add it
again in the future) to avoid userspace foot-guns.
* Expand -EINVAL checks in build_open_flags(). Rather than silently
ignoring silly flag combinations (such as O_TMPFILE|O_PATH or
O_PATH|<most flags>), give an -EINVAL. All of the silent ignore semantics
were added to open(2) because we couldn't return -EINVAL -- but we can
now!
* open(2) and openat(2) clean up their flags before passing them to
build_open_flags(), so all mixed flags will continue to work. There is
one exception which is (O_PATH|O_TMPFILE) -- this is no longer
permitted (as far as I can tell this appears to be a bug, and there are
no userspace users that I've hit after running this code for a few
days). If it turns out that userspace does depend on (O_PATH|O_TMPFILE)
working, we can only disallow it for openat2(2).
* Don't zero out nd->root in complete_walk() for RCU-walk if we're doing a
scoped-lookup (this prevents a needless REF-walk retry).
* Attempt all tests on kernels that don't have openat2(2), rather than just
skipping everything.

For a very long time, extending openat(2) with new features has been
incredibly frustrating. This stems from the fact that openat(2) is
possibly the most famous counter-example to the mantra "don't silently
accept garbage from userspace" -- it doesn't check whether unknown flags
are present[1].
This means that (generally) the addition of new flags to openat(2) has
been fraught with backwards-compatibility issues (O_TMPFILE has to be
defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old
kernels gave errors, since it's insecure to silently ignore the
flag[2]). All new security-related flags therefore have a tough road to
being added to openat(2).
Furthermore, the need for some sort of control over VFS's path resolution (to
avoid malicious paths resulting in inadvertent breakouts) has been a very
long-standing desire of many userspace applications. This patchset is a revival
of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David
Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum
project[5]) with a few additions and changes made based on the previous
discussion within [6] as well as others I felt were useful.
In line with the conclusions of the original discussion of AT_NO_JUMPS, the
flag has been split up into separate flags. However, instead of being an
openat(2) flag it is provided through a new syscall openat2(2) which provides
several other improvements to the openat(2) interface (see the patch
description for more details). The following new LOOKUP_* flags are added:
* LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards,
or through absolute links). Absolute pathnames alone in openat(2) do not
trigger this. Magic-link traversal which implies a vfsmount jump is also
blocked (though magic-link jumps on the same vfsmount are permitted).
* LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style
links. This is done by blocking the usage of nd_jump_link() during
resolution in a filesystem. The term "magic-links" is used to match
with the only reference to these links in Documentation/, but I'm
happy to change the name.
It should be noted that this is different to the scope of
~LOOKUP_FOLLOW in that it applies to all path components. However,
you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it
will *not* fail (assuming that no parent component was a
magic-link), and you will have an fd for the magic-link.
In order to correctly detect magic-links, the introduction of a new
LOOKUP_MAGICLINK_JUMPED state flag was required.
* LOOKUP_BENEATH disallows escapes to outside the starting dirfd's
tree, using techniques such as ".." or absolute links. Absolute
paths in openat(2) are also disallowed. Conceptually this flag is to
ensure you "stay below" a certain point in the filesystem tree --
but this requires some additional to protect against various races
that would allow escape using "..".
Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it
can trivially beam you around the filesystem (breaking the
protection). In future, there might be similar safety checks done as
in LOOKUP_IN_ROOT, but that requires more discussion.
In addition, two new flags are added that expand on the above ideas:
* LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink
resolution is allowed at all, including magic-links. Just as with
LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an
fd for the symlink as long as no parent path had a symlink
component.
* LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than
blocking attempts to move past the root, forces all such movements
to be scoped to the starting point. This provides chroot(2)-like
protection but without the cost of a chroot(2) for each filesystem
operation, as well as being safe against race attacks that chroot(2)
is not.
If a race is detected (as with LOOKUP_BENEATH) then an error is
generated, and similar to LOOKUP_BENEATH it is not permitted to cross
magic-links with LOOKUP_IN_ROOT.
The primary need for this is from container runtimes, which
currently need to do symlink scoping in userspace[7] when opening
paths in a potentially malicious container. There is a long list of
CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT
(such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and
CVE-2019-5736, just to name a few).
In order to make all of the above more usable, I'm working on
libpathrs[8] which is a C-friendly library for safe path resolution. It
features a userspace-emulated backend if the kernel doesn't support
openat2(2). Hopefully we can get userspace to switch to using it, and
thus get openat2(2) support for free once it's ready.

OPENAT2(2) Linux Programmer's Manual OPENAT2(2)
NAME
openat2 - open and possibly create a file (extended)
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
int openat2(int dirfd, const char *pathname, struct open_how *how, size_t size);
Note: There is no glibc wrapper for this system call; see NOTES.
DESCRIPTION
The openat2() system call opens the file specified by pathname. If the specified file
does not exist, it may optionally (if O_CREAT is specified in how.flags) be created by
openat2().
As with openat(2), if pathname is relative, then it is interpreted relative to the
directory referred to by the file descriptor dirfd (or the current working directory of
the calling process, if dirfd is the special value AT_FDCWD.) If pathname is absolute,
then dirfd is ignored (unless how.resolve contains RESOLVE_IN_ROOT, in which case pathname
is resolved relative to dirfd.)
The openat2() system call is an extension of openat(2) and provides a superset of its
functionality. Rather than taking a single flag argument, an extensible structure (how)
is passed instead to allow for future extensions. size must be set to sizeof(struct
open_how), to facilitate future extensions (see the "Extensibility" section of the NOTES
for more detail on how extensions are handled.)
The open_how structure
The following structure indicates how pathname should be opened, and acts as a superset of
the flag and mode arguments to openat(2).
struct open_how {
__aligned_u64 flags; /* O_* flags. */
__u16 mode; /* Mode for O_{CREAT,TMPFILE}. */
__u16 __padding[3]; /* Must be zeroed. */
__aligned_u64 resolve; /* RESOLVE_* flags. */
};
Any future extensions to openat2() will be implemented as new fields appended to the above
structure (or through reuse of pre-existing padding space), with the zero value of the new
fields acting as though the extension were not present.
The meaning of each field is as follows:
flags
The file creation and status flags to use for this operation. All of the
O_* flags defined for openat(2) are valid openat2() flag values.
Unlike openat(2), it is an error to provide openat2() unknown or conflicting
flags in flags.
mode
File mode for the new file, with identical semantics to the mode argument to
openat(2). However, unlike openat(2), it is an error to provide openat2()
with a mode which contains bits other than 0777.
It is an error to provide openat2() a non-zero mode if flags does not
contain O_CREAT or O_TMPFILE.
resolve
Change how the components of pathname will be resolved (see
path_resolution(7) for background information.) The primary use case for
these flags is to allow trusted programs to restrict how untrusted paths (or
paths inside untrusted directories) are resolved. The full list of resolve
flags is given below.
RESOLVE_NO_XDEV
Disallow traversal of mount points during path resolution (including
all bind mounts).
Users of this flag are encouraged to make its use configurable
(unless it is used for a specific security purpose), as bind mounts
are very widely used by end-users. Setting this flag indiscrimnately
for all uses of openat2() may result in spurious errors on
previously-functional systems.
RESOLVE_NO_SYMLINKS
Disallow resolution of symbolic links during path resolution. This
option implies RESOLVE_NO_MAGICLINKS.
If the trailing component is a symbolic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
symbolic link will be returned.
Users of this flag are encouraged to make its use configurable
(unless it is used for a specific security purpose), as symbolic
links are very widely used by end-users. Setting this flag
indiscrimnately for all uses of openat2() may result in spurious
errors on previously-functional systems.
RESOLVE_NO_MAGICLINKS
Disallow all magic link resolution during path resolution.
If the trailing component is a magic link, and flags contains both
O_PATH and O_NOFOLLOW, then an O_PATH file descriptor referencing the
magic link will be returned.
Magic-links are symbolic link-like objects that are most notably
found in proc(5) (examples include /proc/[pid]/exe and
/proc/[pid]/fd/*.) Due to the potential danger of unknowingly
opening these magic links, it may be preferable for users to disable
their resolution entirely (see symboliclink(7) for more details.)
RESOLVE_BENEATH
Do not permit the path resolution to succeed if any component of the
resolution is not a descendant of the directory indicated by dirfd.
This results in absolute symbolic links (and absolute values of
pathname) to be rejected.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
RESOLVE_IN_ROOT
Treat dirfd as the root directory while resolving pathname (as though
the user called chroot(2) with dirfd as the argument.) Absolute
symbolic links and ".." path components will be scoped to dirfd. If
pathname is an absolute path, it is also treated relative to dirfd.
However, unlike chroot(2) (which changes the filesystem root
permanently for a process), RESOLVE_IN_ROOT allows a program to
efficiently restrict path resolution for only certain operations. It
also has several hardening features (such detecting escape attempts
during .. resolution) which chroot(2) does not.
Currently, this flag also disables magic link resolution. However,
this may change in the future. The caller should explicitly specify
RESOLVE_NO_MAGICLINKS to ensure that magic links are not resolved.
It is an error to provide openat2() unknown flags in resolve.
RETURN VALUE
On success, a new file descriptor is returned. On error, -1 is returned, and errno is set
appropriately.
ERRORS
The set of errors returned by openat2() includes all of the errors returned by openat(2),
as well as the following additional errors:
EINVAL An unknown flag or invalid value was specified in how.
EINVAL mode is non-zero, but flags does not contain O_CREAT or O_TMPFILE.
EINVAL size was smaller than any known version of struct open_how.
E2BIG An extension was specified in how, which the current kernel does not support (see
the "Extensibility" section of the NOTES for more detail on how extensions are
handled.)
EAGAIN resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and the kernel could
not ensure that a ".." component didn't escape (due to a race condition or
potential attack.) Callers may choose to retry the openat2() call.
EXDEV resolve contains either RESOLVE_IN_ROOT or RESOLVE_BENEATH, and an escape from the
root during path resolution was detected.
EXDEV resolve contains RESOLVE_NO_XDEV, and a path component attempted to cross a mount
point.
ELOOP resolve contains RESOLVE_NO_SYMLINKS, and one of the path components was a symbolic
link (or magic link).
ELOOP resolve contains RESOLVE_NO_MAGICLINKS, and one of the path components was a magic
link.
VERSIONS
openat2() was added to Linux in kernel 5.FOO.
CONFORMING TO
This system call is Linux-specific.
The semantics of RESOLVE_BENEATH were modelled after FreeBSD's O_BENEATH.
NOTES
Glibc does not provide a wrapper for this system call; call it using systemcall(2).
Extensibility
In order to allow for struct open_how to be extended in future kernel revisions, openat2()
requires userspace to specify the size of struct open_how structure they are passing. By
providing this information, it is possible for openat2() to provide both forwards- and
backwards-compatibility — with size acting as an implicit version number (because new
extension fields will always be appended, the size will always increase.) This
extensibility design is very similar to other system calls such as perf_setattr(2),
perf_event_open(2), and clone(3).
If we let usize be the size of the structure according to userspace and ksize be the size
of the structure which the kernel supports, then there are only three cases to consider:
* If ksize equals usize, then there is no version mismatch and how can be used
verbatim.
* If ksize is larger than usize, then there are some extensions the kernel
supports which the userspace program is unaware of. Because all extensions must
have their zero values be a no-op, the kernel treats all of the extension fields
not set by userspace to have zero values. This provides backwards-
compatibility.
* If ksize is smaller than usize, then there are some extensions which the
userspace program is aware of but the kernel does not support. Because all
extensions must have their zero values be a no-op, the kernel can safely ignore
the unsupported extension fields if they are all-zero. If any unsupported
extension fields are non-zero, then -1 is returned and errno is set to E2BIG.
This provides forwards-compatibility.
Therefore, most userspace programs will not need to have any special handling of
extensions. However, if a userspace program wishes to determine what extensions the
running kernel supports, they may conduct a binary search on size (to find the largest
value which doesn't produce an error of E2BIG.)

[PATCH v2 linux-kselftest-test 0/3] kunit: support building core/tests as modules
by Alan Maguire
The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel. The aim of this series is to allow
building kunit itself and tests as modules. This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.
Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch as a candidate to be applied to the
test tree before too many kunit consumers appear. We attempt to deal
with existing consumers in patch 1.
Changes since v1:
- sent correct patch set; apologies, previous patch set was built
prior to kunit move to lib/ and should be ignored.
Patch 1 consists changes needed to support loading tests as modules.
Patch 2 allows kunit itself to be loaded as a module.
Patch 3 documents module support.
Alan Maguire (3):
kunit: allow kunit tests to be loaded as a module
kunit: allow kunit to be loaded as a module
kunit: update documentation to describe module-based build

[PATCH linux-kselftest/test v5] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
v5 replaces the use of KUNIT_ASSERT_NOT_ERR_OR_NULL() -- to check the
return value from kzalloc() and kmalloc() -- with the __GFP_NOFAIL
arugment. (Both in the list_test_list_init test.)
Earlier versions of the test can be found:

[PATCH linux-kselftest/test v4] lib/list-test: add a test for the 'list' doubly linked list
by David Gow
Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Signed-off-by: David Gow <davidgow(a)google.com>
---
The changes from v3 are mostly to do with naming:
- The Kconfig entry has been renamed from LIST_TEST to LIST_KUNIT_TEST,
which matches the SYSCTL_KUNIT_TEST entry,
- The Kconfig description was updated to better match other KUnit tests,
specifying that the test is not intended for use in a production
kernel. A now-redundant mention of the test running a boot was
removed.
- The MAINTAINERS entry refers to a "KUNIT TEST" rather than a "UNIT
TEST"
- The module name has changed from "list-test" to "list-kunit-test".
Earlier versions of the test can be found:
