[PATCH v3 0/4] Implement FUTEX_WAIT_MULTIPLE operation
by André Almeida
Hello,
This patchset implements a new futex operation, called FUTEX_WAIT_MULTIPLE,
which allows a thread to wait on several futexes at the same time, and be
awoken by any of them.
The use case lies in the Wine implementation of the Windows NT interface
WaitMultipleObjects. This Windows API function allows a thread to sleep
waiting on the first of a set of event sources (mutexes, timers, signal,
console input, etc) to signal. Considering this is a primitive
synchronization operation for Windows applications, being able to quickly
signal events on the producer side, and quickly go to sleep on the
consumer side is essential for good performance of those running over Wine.
Since this API exposes a mechanism to wait on multiple objects, and
we might have multiple waiters for each of these events, a M->N
relationship, the current Linux interfaces fell short on performance
evaluation of large M,N scenarios. We experimented, for instance, with
eventfd, which has performance problems discussed below, but we also
experimented with userspace solutions, like making each consumer wait on
a condition variable guarding the entire list of objects, and then
waking up multiple variables on the producer side, but this is
prohibitively expensive since we either need to signal many condition
variables or share that condition variable among multiple waiters, and
then verify for the event being signaled in userspace, which means
dealing with often false positive wakes ups.
The natural interface to implement the behavior we want, also
considering that one of the waitable objects is a mutex itself, would be
the futex interface. Therefore, this patchset proposes a mechanism for
a thread to wait on multiple futexes at once, and wake up on the first
futex that was awaken.
In particular, using futexes in our Wine use case reduced the CPU
utilization by 4% for the game Beat Saber and by 1.5% for the game
Shadow of Tomb Raider, both running over Proton (a Wine based solution
for Windows emulation), when compared to the eventfd interface. This
implementation also doesn't rely of file descriptors, so it doesn't risk
overflowing the resource.
In time, we are also proposing modifications to glibc and libpthread to
make this feature available for Linux native multithreaded applications
using libpthread, which can benefit from the behavior of waiting on any
of a group of futexes.
Technically, the existing FUTEX_WAIT implementation can be easily
reworked by using futex_wait_multiple() with a count of one, and I
have a patch showing how it works. I'm not proposing it, since
futex is such a tricky code, that I'd be more comfortable to have
FUTEX_WAIT_MULTIPLE running upstream for a couple development cycles,
before considering modifying FUTEX_WAIT.
The patch series includes an extensive set of kselftests validating
the behavior of the interface. We also implemented support[1] on
Syzkaller and survived the fuzzy testing.
Finally, if you'd rather pull directly a branch with this set you can
find it here:

The RFC for this patch can be found here:
https://lkml.org/lkml/2019/7/30/1399
=== Performance of eventfd ===
Polling on several eventfd contexts with semaphore semantics would
provide us with the exact semantics we are looking for. However, as
shown below, in a scenario with sufficient producers and consumers, the
eventfd interface itself becomes a bottleneck, in particular because
each thread will compete to acquire a sequence of waitqueue locks for
each eventfd context in the poll list. In addition, in the uncontended
case, where the producer is ready for consumption, eventfd still
requires going into the kernel on the consumer side.
When a write or a read operation in an eventfd file succeeds, it will try
to wake up all threads that are waiting to perform some operation to
the file. The lock (ctx->wqh.lock) that hold the access to the file value
(ctx->count) is the same lock used to control access the waitqueue. When
all those those thread woke, they will compete to get this lock. Along
with that, the poll() also manipulates the waitqueue and need to hold
this same lock. This lock is specially hard to acquire when poll() calls
poll_freewait(), where it tries to free all waitqueues associated with
this poll. While doing that, it will compete with a lot of read and
write operations that have been waken.
In our use case, with a huge number of parallel reads, writes and polls,
this lock is a bottleneck and hurts the performance of applications. Our
implementation of futex, however, decrease the calls of spin lock by more
than 80% in some user applications.
Finally, eventfd operates on file descriptors, which is a limited
resource that has shown its limitation in our use cases. Despite the
Windows interface not waiting on more than 64 objects at once, we still
have multiple waiters at the same time, and we were easily able to
exhaust the FD limits on applications like games.
Thanks,
André

[PATCH bpf-next v3 09/12] selftests: bpf: don't listen() on UDP sockets
by Lorenz Bauer
Most tests for TCP sockmap can be adapted to UDP sockmap if the
listen call is skipped. Rename listen_loopback, etc. to socket_loopback
and skip listen() for SOCK_DGRAM.

[PATCH bpf 1/2] bpf, x32: fix bug with JMP32 JSET BPF_X checking upper bits
by Luke Nelson
The current x32 BPF JIT is incorrect for JMP32 JSET BPF_X when the upper
32 bits of operand registers are non-zero in certain situations.
The problem is in the following code:
case BPF_JMP | BPF_JSET | BPF_X:
case BPF_JMP32 | BPF_JSET | BPF_X:
...
/* and dreg_lo,sreg_lo */
EMIT2(0x23, add_2reg(0xC0, sreg_lo, dreg_lo));
/* and dreg_hi,sreg_hi */
EMIT2(0x23, add_2reg(0xC0, sreg_hi, dreg_hi));
/* or dreg_lo,dreg_hi */
EMIT2(0x09, add_2reg(0xC0, dreg_lo, dreg_hi));
This code checks the upper bits of the operand registers regardless if
the BPF instruction is BPF_JMP32 or BPF_JMP64. Registers dreg_hi and
dreg_lo are not loaded from the stack for BPF_JMP32, however, they can
still be polluted with values from previous instructions.
The following BPF program demonstrates the bug. The jset64 instruction
loads the temporary registers and performs the jump, since ((u64)r7 &
(u64)r8) is non-zero. The jset32 should _not_ be taken, as the lower
32 bits are all zero, however, the current JIT will take the branch due
the pollution of temporary registers from the earlier jset64.
mov64 r0, 0
ld64 r7, 0x8000000000000000
ld64 r8, 0x8000000000000000
jset64 r7, r8, 1
exit
jset32 r7, r8, 1
mov64 r0, 2
exit
The expected return value of this program is 2; under the buggy x32 JIT
it returns 0. The fix is to skip using the upper 32 bits for jset32 and
compare the upper 32 bits for jset64 only.
All tests in test_bpf.ko and selftests/bpf/test_verifier continue to
pass with this change.
We found this bug using our automated verification tool, Serval.

WARNING: kernel/bpf/verifier.c:8186 bpf_check+0x2332/0x30a4
by Naresh Kamboju
This is an informative email report,
On linux-next while running kselftest bpf test_verifier, the following
kernel warning reported. But this seems to be NOT a kernel regression
after reading the commit log.
Started noticing from 5.6.0-rc3-next-20200226 and still happening on
5.6.0-rc4-next-20200306.
Suspecting patch,
commit id 94dacdbd5d2dfa2cffd308f128d78c99f855f5be
"
bpf: Tighten the requirements for preallocated hash maps
<>
So preallocation _must_ be enforced for all variants of intrusive
instrumentation.
Unfortunately immediate enforcement would break backwards compatibility, so
for now such programs still are allowed to run, but a one time warning is
emitted in dmesg and the verifier emits a warning in the verifier log as
well so developers are made aware about this and can fix their programs
before the enforcement becomes mandatory.

[RFC PATCH 0/1] kvm: selftests: Add TEST_FAIL macro

The following patch's commit message is self-explanatory about this proposal.
I adjusted to use TEST_FAIL only a few source files, in reality it will
need to change all the ones listed below. I will proceed with the
adjustments if this new macro idea is accepted.
$ find . -type f -name "*.c" -exec grep -l "TEST_ASSERT(false" {} \;

[PATCH AUTOSEL 5.4 18/58] selftests/rseq: Fix out-of-tree compilation
by Sasha Levin
From: Michael Ellerman <mpe(a)ellerman.id.au>
[ Upstream commit ef89d0545132d685f73da6f58b7e7fe002536f91 ]
Currently if you build with O=... the rseq tests don't build:
$ make O=$PWD/output -C tools/testing/selftests/ TARGETS=rseq

...

/usr/bin/ld: cannot find -lrseq
collect2: error: ld returned 1 exit status
This is because the library search path points to the source
directory, not the output.
We can fix it by changing the library search path to $(OUTPUT).

[PATCH AUTOSEL 5.5 21/67] kunit: run kunit_tool from any directory
by Sasha Levin
From: Heidi Fahim <heidifahim(a)google.com>
[ Upstream commit be886ba90cce2fb2f5a4dbcda8f3be3fd1b2f484 ]
Implemented small fix so that the script changes work directories to the
root of the linux kernel source tree from which kunit.py is run. This
enables the user to run kunit from any working directory. Originally
considered using os.path.join but this is more error prone as we would
have to find all file path usages and modify them accordingly. Using
os.chdir ensures that the entire script is run within /linux.

[PATCH] selftests: Add support for argc and argv.
by Kuniyuki Iwashima
Currently tests are often written in C and shell script. In many cases, the
script passes some arguments to the C program. However, the helper
functions do not support arguments, so many tests are written without
helper functions.
This patch allows us to handle argc and argv in each tests and makes it
easier to write tests flexibly with helper functions.

[PATCH] selftests/powerpc: Turn off timeout setting for benchmarks, dscr, signal, tm
by Po-Hsu Lin
Some specific tests in powerpc can take longer than the default 45
seconds that added in commit 852c8cbf (selftests/kselftest/runner.sh:
Add 45 second timeout per test) to run, the following test result was
collected across 2 Power8 nodes and 1 Power9 node in our pool:
powerpc/benchmarks/futex_bench - 52s
powerpc/dscr/dscr_sysfs_test - 116s
powerpc/signal/signal_fuzzer - 88s
powerpc/tm/tm_unavailable_test - 168s
powerpc/tm/tm-poison - 240s
Thus they will fail with TIMEOUT error. Disable the timeout setting
for these sub-tests to allow them finish properly.

[PATCH] selftests/ftrace: Use printf instead of echo in kprobe syntax error tests
by Seth Forshee
Test cases which use echo to write strings containing backslashes
fail with some shells, as echo's treatment of backslashes in
strings varies between shell implementations. Use printf instead,
as it should behave consistently across different shells. This
requires adjustments to the strings to escape \ and % characters.
ftrace_errlog_check() must also re-escape these characters after
processing them to remove ^ characters.

[PATCH v28 22/22] selftests/x86: Add vDSO selftest for SGX
by Jarkko Sakkinen
Expand the selftest by invoking the enclave by using
__vdso_sgx_enter_enclave() in addition to direct ENCLS[EENTER].

[PATCH] kvm: selftests: Support dirty log initial-all-set test
by Jay Zhou
Since the new capability KVM_DIRTY_LOG_INITIALLY_SET of
KVM_CAP_MANUAL_DIRTY_LOG_PROTECT2 has been introduced, tweak the
clear_dirty_log_test to test it.

[PATCH AUTOSEL 4.14 03/22] selftests: fix too long argument
by Sasha Levin
From: Jiri Benc <jbenc(a)redhat.com>
[ Upstream commit c363eb48ada5cf732b3f489fab799fc881097842 ]
With some shells, the command construed for install of bpf selftests becomes
too large due to long list of files:
make[1]: execvp: /bin/sh: Argument list too long
make[1]: *** [../lib.mk:73: install] Error 127
Currently, each of the file lists is replicated three times in the command:
in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that
by one instance by using make conditionals and separate the echo and rsync
into two shell commands. (One would be inclined to just remove the '@' at
the beginning of the rsync command and let 'make' echo it by itself;
unfortunately, it appears that the '@' in the front of mkdir silences output
also for the following commands.)
Also, separate handling of each of the lists to its own shell command.
The semantics of the makefile is unchanged before and after the patch. The
ability of individual test directories to override INSTALL_RULE is retained.

[PATCH AUTOSEL 4.19 13/32] selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testing
by Sasha Levin
From: Hangbin Liu <liuhangbin(a)gmail.com>
[ Upstream commit e8023b030ce1748930e2dc76353a262fe47d4745 ]
For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.
So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.
For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.
Before the fix:
]# ./mirror_gre.sh
TEST: ingress mirror to gretap (skip_hw) [ OK ]
TEST: egress mirror to gretap (skip_hw) [ OK ]
TEST: ingress mirror to ip6gretap (skip_hw) [ OK ]
TEST: egress mirror to ip6gretap (skip_hw) [ OK ]
TEST: ingress mirror to gretap: envelope MAC (skip_hw) [FAIL]
Expected to capture 10 packets, got 0.

TEST: egress mirror to ip6gretap: envelope MAC (skip_hw) [FAIL]
Expected to capture 10 packets, got 0.
TEST: two simultaneously configured mirrors (skip_hw) [ OK ]

to capture 10 packets, got 0". So let's choose a smaller tos value for
testing.

[PATCH AUTOSEL 5.4 18/58] selftests: forwarding: use proto icmp for {gretap, ip6gretap}_mac testing
by Sasha Levin
From: Hangbin Liu <liuhangbin(a)gmail.com>
[ Upstream commit e8023b030ce1748930e2dc76353a262fe47d4745 ]
For tc ip_proto filter, when we extract the flow via __skb_flow_dissect()
without flag FLOW_DISSECTOR_F_STOP_AT_ENCAP, we will continue extract to
the inner proto.
So for GRE + ICMP messages, we should not track GRE proto, but inner ICMP
proto.
For test mirror_gre.sh, it may make user confused if we capture ICMP
message on $h3(since the flow is GRE message). So I move the capture
dev to h3-gt{4,6}, and only capture ICMP message.
Before the fix:

0x11 and 0x12 set the ECN bits based on RFC2474, it would be better to avoid
that. 0x14 and 0x18 would be better and works as well.

[PATCH v2 0/7] kunit: create a centralized executor to dispatch all KUnit tests
by Brendan Higgins
## TL;DR
This patchset adds a centralized executor to dispatch tests rather than
relying on late_initcall to schedule each test suite separately along
with a couple of new features that depend on it.
## What am I trying to do?
Conceptually, I am trying to provide a mechanism by which test suites
can be grouped together so that they can be reasoned about collectively.
The last two of three patches in this series add features which depend
on this:
PATCH 5/7 Prints out a test plan right before KUnit tests are run[1];
this is valuable because it makes it possible for a test
harness to detect whether the number of tests run matches the
number of tests expected to be run, ensuring that no tests
silently failed.
PATCH 6/7 Add a new kernel command-line option which allows the user to
specify that the kernel poweroff, halt, or reboot after
completing all KUnit tests; this is very handy for running
KUnit tests on UML or a VM so that the UML/VM process exits
cleanly immediately after running all tests without needing a
special initramfs.
In addition, by dispatching tests from a single location, we can
guarantee that all KUnit tests run after late_init is complete, which
was a concern during the initial KUnit patchset review (this has not
been a problem in practice, but resolving with certainty is nevertheless
desirable).
Other use cases for this exist, but the above features should provide an
idea of the value that this could provide.

[PATCH v5 kunit-next 0/4] kunit: add debugfs representation to show results
by Alan Maguire
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
Changes since v4:
- added suite-level log expectations to kunit log test (Brendan, patch 2)
- added log expectations (of it being NULL) for case where
CONFIG_KUNIT_DEBUGFS=n to kunit log test (patch 2)
- added patch 3 which replaces subtest tab indentation with 4 space
indentation as per TAP 14 spec (Frank, patch 3)
Changes since v3:
- added CONFIG_KUNIT_DEBUGFS to support conditional compilation of debugfs
representation, including string logging (Frank, patch 1)
- removed unneeded NULL check for test_case in
kunit_suite_for_each_test_case() (Frank, patch 1)
- added kunit log test to verify logging multiple strings works
(Frank, patch 2)
- rephrased description of results file (Frank, patch 3)
Changes since v2:
- updated kunit_status2str() to kunit_status_to_string() and made it
static inline in include/kunit/test.h (Brendan)
- added log string to struct kunit_suite and kunit_case, with log
pointer in struct kunit pointing at the case log. This allows us
to collect kunit_[err|info|warning]() messages at the same time
as we printk() them. This solves for the most part the sharing
of log messages between test execution and debugfs since we
just print the suite log (which contains the test suite preamble)
and the individual test logs. The only exception is the suite-level
status, which we cannot store in the suite log as it would mean
we'd print the suite and its status prior to the suite's results.
(Brendan, patch 1)
- dropped debugfs-based kunit run patch for now so as not to cause
problems with tests currently under development (Brendan)
- fixed doc issues with code block (Brendan, patch 3)
Changes since v1:
- trimmed unneeded include files in lib/kunit/debugfs.c (Greg)
- renamed global debugfs functions to be prefixed with kunit_ (Greg)
- removed error checking for debugfs operations (Greg)
Alan Maguire (4):

[RFC v1 0/6] kunit: create a centralized executor to dispatch all KUnit tests
by Brendan Higgins
## TL;DR
This patchset adds a centralized executor to dispatch tests rather than
relying on late_initcall to schedule each test suite separately along
with a couple of new features that depend on it.
## What am I trying to do?
Conceptually, I am trying to provide a mechanism by which test suites
can be grouped together so that they can be reasoned about collectively.
The last two patches in this series add features which depend on this:
RFC 5/6 Prints out a test plan right before KUnit tests are run[1]; this
is valuable because it makes it possible for a test harness to
detect whether the number of tests run matches the number of
tests expected to be run, ensuring that no tests silently
failed.
RFC 6/6 Add a new kernel command-line option which allows the user to
specify that the kernel poweroff, halt, or reboot after
completing all KUnit tests; this is very handy for running KUnit
tests on UML or a VM so that the UML/VM process exits cleanly
immediately after running all tests without needing a special
initramfs.
In addition, by dispatching tests from a single location, we can
guarantee that all KUnit tests run after late_init is complete, which
was a concern during the initial KUnit patchset review (this has not
been a problem in practice, but resolving with certainty is nevertheless
desirable).
Other use cases for this exist, but the above features should provide an
idea of the value that this could provide.
## What work remains to be done?
These patches were based on patches in our non-upstream branch[2], so we
have a pretty good idea that they are useable as presented;
nevertheless, some of the changes done in this patchset could
*definitely* use some review by subsystem experts (linker scripts, init,
etc), and will likely change a lot after getting feedback.
The biggest thing that I know will require additional attention is
integrating this patchset with the KUnit module support patchset[3]. I
have not even attempted to build these patches on top of the module
support patches as I would like to get people's initial thoughts first
(especially Alan's :-) ). I think that making these patches work with
module support should be fairly straight forward, nevertheless.

[PATCH v18 00/24] selftests, powerpc, x86: Memory Protection Keys
by Sandipan Das
Memory protection keys enables an application to protect its address
space from inadvertent access by its own code.
This feature is now enabled on powerpc and has been available since
4.16-rc1. The patches move the selftests to arch neutral directory
and enhance their test coverage.
Tested on powerpc64 and x86_64 (Skylake-SP).
Link to development branch:
https://github.com/sandip4n/linux/tree/pkey-selftests
Changelog
---------
Link to previous version (v17):
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=154174
v18:
(1) Fixed issues with x86 multilib builds based on
feedback from Dave.
(2) Moved patch 2 to the end of the series.
v17:
(1) Fixed issues with i386 builds when running on x86_64
based on feedback from Dave.
(2) Replaced patch 6 from previous version with patch 7.
This addresses u64 format specifier related concerns
that Michael had raised in v15.
v16:
(1) Rebased on top of latest master.
(2) Switched to u64 instead of using an arch-dependent
pkey_reg_t type for references to the pkey register
based on suggestions from Dave, Michal and Michael.
(3) Removed build time determination of page size based
on suggestion from Michael.
(4) Fixed comment before the definition of __page_o_noops()
from patch 13 ("selftests/vm/pkeys: Introduce powerpc
support").
v15:
(1) Rebased on top of latest master.
(2) Addressed review comments from Dave Hansen.
(3) Moved code for getting or setting pkey bits to new
helpers. These changes replace patch 7 of v14.
(4) Added a fix which ensures that the correct count of
reserved keys is used across different platforms.
(5) Added a fix which ensures that the correct page size
is used as powerpc supports both 4K and 64K pages.
v14:
(1) Incorporated another round of comments from Dave Hansen.
v13:
(1) Incorporated comments for Dave Hansen.
(2) Added one more test for correct pkey-0 behavior.
v12:
(1) Fixed the offset of pkey field in the siginfo structure for
x86_64 and powerpc. And tries to use the actual field
if the headers have it defined.
v11:
(1) Fixed a deadlock in the ptrace testcase.
v10 and prior:
(1) Moved the testcase to arch neutral directory.
(2) Split the changes into incremental patches.

[ANN] Kselftest integration into Kernel CI
by Shuah Khan
Integrating Kselftest into Kernel CI rings depends on Kselftest build
and install framework to support Kernel CI use-cases. I am kicking off
an effort to support Kselftest runs in Kernel CI rings. Running these
tests in Kernel CI rings will help quality of kernel releases, both
stable and mainline.
What is required for full support?
1. Cross-compilation & relocatable build support
2. Generates objects in objdir/kselftest without cluttering main objdir
3. Leave source directory clean
4. Installs correctly in objdir/kselftest/kselftest_install and adds
itself to run_kselftest.sh script generated during install.
Note that install step is necessary for all files to be installed for
run time support.
I looked into the current status and identified problems. The work is
minimal to add full support. Out of 80+ tests, 7 fail to cross-build
and 1 fails to install correctly.
List is below:
Tests fails to build: bpf, capabilities, kvm, memfd, mqueue, timens, vm
Tests fail to install: android (partial failure)
Leaves source directory dirty: bpf, seccomp
I have patches ready for the following issues:
Kselftest objects (test dirs) clutter top level object directory.
seccomp_bpf generates objects in the source directory.
I created a topic branch to collect all the patches:
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/?…
I am going to start working on build problems. If anybody is
interested in helping me with this effort, don't hesitate to
contact me. I first priority is fixing build and install and
then look into tests that leave the source directory dirty.
Detailed report can be found here:
https://drive.google.com/file/d/11nnWOKIzzOrE4EiucZBn423lzSU_eNNv/view?usp=…

[PATCH bpf-next v2 6/9] selftests: bpf: don't listen() on UDP sockets
by Lorenz Bauer
Most tests for TCP sockmap can be adapted to UDP sockmap if the
listen call is skipped. Rename listen_loopback, etc. to socket_loopback
and skip listen() for SOCK_DGRAM.

[PATCH 1/2] kunit: kunit_parser: making parser more robust
by Heidi Fahim
Previously, kunit_parser did not properly handle kunit TAP output that
- had any prefixes (generated from different configs)
- had unrelated kernel output mixed in the middle of it, which has
shown up when testing with allyesconfig
To remove prefixes, the parser looks for the first line that includes
TAP output, "TAP version 14". It then determines the length of the
string before this sequence, and strips that number of characters off
the beginning of the following lines until the last KUnit output line is
reached.
These fixes have been tested with additional tests in the
KUnitParseTest and their associated logs have also been added.

[PATCH v5 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[*], 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.
v5:
- Rebase to tip/master, ec7b10f2d023 ("Merge branch 'x86/cleanups'")
- Fix a missing IA32_FEAT_CTL change in the idle driver (which amusingly
reads the MSR to deal with SGX). [kbuild test robot]
- Tweak the displayed names for VMX flags. [Boris, Paolo, Liran]
- Add a comment above the raw rdmsr() calls in the VMX feature flag
parsing. [Boris]
- Fix a few changelog typos. [Boris]
- Use VMX_F() instead of F() for the VMX flag extraction macro. [Boris]
- Drop 'PROC' from the PRIMARY_CTLS and SECONDARY_CTLS enums to keep
line lengths sane.
- Keep the pr_fmt at the top of feat_ctl.c when the flag populating code
is introduced (previously got buried in the middle of the file).
v4:
- Rebase to tip/master, 8a1b070333f4 ("Merge branch 'WIP.x86/mm'")
- Rename everything feature control related to IA32_FEAT_CTL. [Boris]
- Minor coding style tweaks [Boris and Jarkko].
- Print VMX feature flags in "vmx flags" to avoid polluting "flags",
but keep printing the current synthetic VMX in "flags" so as not to
break the ABI. [Boris]
- Don't bother printing an error message in the extremely unlikely
event VMX is supported but IA32_FEAT_CTL doesn't exist. [Boris]
- Beef up a few changelogs and comments. [Boris]
- Add a comment in the LMCE code for the new WARN. [Jarkko]
- Check CONFIG_KVM_INTEL instead of CONFIG_KVM when deciding whether
or not to enable VMX.
- Add a patch to introduce X86_FEATURE_MSR_IA32_FEAT_CTL.
- Dropped Jim's Reviewed-by from a few KVM patches due to the above
addition.
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 typo [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/vm: Fix map_hugetlb length used for testing read and write
by Christophe Leroy
Commit fa7b9a805c79 ("tools/selftest/vm: allow choosing mem size and
page size in map_hugetlb") added the possibility to change the size
of memory mapped for the test, but left the read and write test using
the default value. This is unnoticed when mapping a length greater
than the default one, but segfaults otherwise.
Fix read_bytes() and write_bytes() by giving them the real length.
Also fix the call to munmap().

Ok. This is to have a guarantee that the underlying_object (e.g. the

Patch 5 adds a call to landlock_release_inode(underlying_object, object)
(LANDLOCK_OBJECT_INODE case), which can sleep e.g., with a call to iput().

Well, it may not look nice but don't you think it is better than a

I just replied to Jann about this subject. This is to "unbalance" the
counter to potentially free it (if there is no more user). I explain it
here:

[PATCH] selftest/lkdtm: Use local .gitignore
by Christophe Leroy
Commit 68ca0fd272da ("selftest/lkdtm: Don't pollute 'git status'")
introduced patterns for git to ignore files generated in
tools/testing/selftests/lkdtm/
Use local .gitignore file instead of using the root one.

[PATCH bpf-next v4 0/5] Make probes which emit dmesg warnings optional
by Michal Rostecki
Feature probes in bpftool related to bpf_probe_write_user and
bpf_trace_printk helpers emit dmesg warnings which might be confusing
for people running bpftool on production environments. This patch series
addresses that by filtering them out by default and introducing the new
positional argument "full" which enables all available probes.
The main motivation behind those changes is ability the fact that some
probes (for example those related to "trace" or "write_user" helpers)
emit dmesg messages which might be confusing for people who are running
on production environments. For details see the Cilium issue[0].
v1 -> v2:
- Do not expose regex filters to users, keep filtering logic internal,
expose only the "full" option for including probes which emit dmesg
warnings.
v2 -> v3:
- Do not use regex for filtering out probes, use function IDs directly.
- Fix bash completion - in v2 only "prefix" was proposed after "macros",
"dev" and "kernel" were not.
- Rephrase the man page paragraph, highlight helper function names.
- Remove tests which parse the plain output of bpftool (except the
header/macros test), focus on testing JSON output instead.
- Add test which compares the output with and without "full" option.
v3 -> v4:
- Use enum to check for helper functions.
- Make selftests compatible with older versions of Python 3.x than 3.7.

Why is this a tty driver?
Have you worked with the V4L developers to tie this into the proper
in-kernel apis for this type of functionality?
Using a tty driver seems like the totally incorrect way to do this, what
am I missing?
Also, do not make up random error values, you return "-1" a lot here,
that is not ok. Please fix up to return the correct -Ewhatever values
instead.

[PATCH v2 0/7] firmware: add partial read support in request_firmware_into_buf
by Scott Branden
This patch series adds partial read support in request_firmware_into_buf.
In order to accept the enhanced API it has been requested that kernel
selftests and upstreamed driver utilize the API enhancement and so
are included in this patch series.
Also in this patch series is the addition of a new Broadcom VK driver
utilizing the new request_firmware_into_buf enhanced API.
Scott Branden (7):
fs: introduce kernel_pread_file* support
firmware: add offset to request_firmware_into_buf
test_firmware: add partial read support for request_firmware_into_buf
firmware: test partial file reads of request_firmware_into_buf
bcm-vk: add bcm_vk UAPI
misc: bcm-vk: add Broadcom VK driver

[PATCH] selftests/timers: Turn off timeout setting
by Po-Hsu Lin
Tests in timers especially nsleep-lat, set-timer-lat,
inconsistency-check and raw_skew these 4 tests can take longer than
the default 45 seconds that introduced in commit 852c8cbf
(selftests/kselftest/runner.sh: Add 45 second timeout per test) to run.
Disable the timeout setting for timers instead of looking for an proper
value to make it more general.

[PATCH bpf-next v2 0/5] bpftool: Make probes which emit dmesg warnings optional
by Michal Rostecki
Feature probes in bpftool related to bpf_probe_write_user and
bpf_trace_printk helpers emit dmesg warnings which might be confusing
for people running bpftool on production environments. This patch series
addresses that by filtering them out by default and introducing the new
positional argument "full" which enables all available probes.
The main motivation behind those changes is ability the fact that some
probes (for example those related to "trace" or "write_user" helpers)
emit dmesg messages which might be confusing for people who are running
on production environments. For details see the Cilium issue[0].
v1: https://lore.kernel.org/bpf/20200218190224.22508-1-mrostecki@opensuse.org/T/
v1 -> v2:
- Do not expose regex filters to users, keep filtering logic internal,
expose only the "full" option for including probes which emit dmesg
warnings.
[0] https://github.com/cilium/cilium/issues/10048
Michal Rostecki (5):
bpftool: Move out sections to separate functions
bpftool: Make probes which emit dmesg warnings optional
bpftool: Update documentation of "bpftool feature" command
bpftool: Update bash completion for "bpftool feature" command
selftests/bpf: Add test for "bpftool feature" command

[PATCH v27 12/22] 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 0/7] firmware: add partial read support in request_firmware_into_buf
by Scott Branden
This patch series adds partial read support in request_firmware_into_buf.
In order to accept the enhanced API it has been requested that kernel
selftests and upstreamed driver utilize the API enhancement and so
are included in this patch series.
Also, no tests existed for existing request_firmware_into_buf kernel API.
Therefore tests have been created and submitted upstream here:
"[PATCH v2 0/2] firmware: selftest for request_firmware_into_buf"
https://lkml.org/lkml/2019/8/22/1367
The firmware selftests patches here require those patches to
be applied first in order for the firmware selftest patches in this
series to be valid.
Finally, in this patch series is the addition of a new Broadcom Valkyrie driver
utilizing the new request_firmware_into_buf enhanced API.
Scott Branden (7):
fs: introduce kernel_pread_file* support
firmware: add offset to request_firmware_into_buf
test_firmware: add partial read support for request_firmware_into_buf
selftests: firmware: Test partial file reads of
request_firmware_into_buf

[PATCH v12 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.
This is patch 1 of an 9 patch series.
Problem:
Currently tasks attempting to reserve 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 reserve
more hugetlb memory than its hugetlb_cgroup limit allows, the kernel
will allow the mmap/shmget call, but will SIGBUS the task when it
attempts to fault in the excess memory.
We have users hitting their hugetlb_cgroup limits and thus we've been
looking at this failure mode. We'd like to improve this behavior such
that users 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. This gives the user an opportunity to fallback
more gracefully to non-hugetlbfs memory for example.
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.rsvd.[limit|usage|max_usage]_in_bytes'. This counter has
slightly different semantics than
'hugetlb.xMB.[limit|usage|max_usage]_in_bytes':
- While usage_in_bytes tracks all *faulted* hugetlb memory,
rsvd.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 rsvd.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.
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 rsvd.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 rsvd.limit_in_bytes concurrently, and this
approach gives them the option to do so.
Testing:
- Added tests passing.
- Used libhugetlbfs for regression testing.

[PATCH] selftests: Install settings files to fix TIMEOUT failures
by Michael Ellerman
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") added a 45 second timeout for tests, and also added
a way for tests to customise the timeout via a settings file.
For example the ftrace tests take multiple minutes to run, so they
were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off
timeout setting").
This works when the tests are run from the source tree. However if the
tests are installed with "make -C tools/testing/selftests install",
the settings files are not copied into the install directory. When the
tests are then run from the install directory the longer timeouts are
not applied and the tests timeout incorrectly.
So add the settings files to TEST_FILES of the appropriate Makefiles
to cause the settings files to be installed using the existing install
logic.
Fixes: 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test")

What would be helpful is to write bpf tests such that older tests that
worked on older llvm versions continue to work and with some indication
on which tests require new bleeding edge tools.

It would be helpful if you can elaborate why latest tools are a
requirement.

Skipping tests will be useless. I am with you on that. However,
figuring out how to maintain some level of backward compatibility
to run at least older tests and warn users to upgrade would be
helpful.
I suspect currently users are ignoring bpf failures because they
are unable to keep up with the requirement to install newer tools
to run the tests. This isn't great either.
Users that care are sharing their pain to see if they can get some
help or explanation on why new tools are required every so often.
I don't think everybody understands why. :)

This is because the library search path points to the source

We can fix it by changing the library search path to $(OUTPUT).

[PATCH v6 0/6] mm/hmm/test: add self tests for HMM
by Ralph Campbell
This series adds new functions to the mmu interval notifier API to
allow device drivers with MMUs to dynamically mirror a process' page
tables based on device faults and invalidation callbacks. The Nouveau
driver is updated to use the extended API and a set of stand alone self
tests is added to help validate and maintain correctness.
The patches are based on linux-5.5.0-rc6 and are for Jason's rdma/hmm tree
since I believe he is planning some interval notifier changes.
Changes v5 -> v6:
Rebase to linux-5.5.0-rc6
Refactored mmu interval notifier patches
Converted nouveau to use the new mmu interval notifier API
Changes v4 -> v5:
Added mmu interval notifier insert/remove/update callable from the
invalidate() callback
Updated HMM tests to use the new core interval notifier API
Changes v1 -> v4:

[PATCH v2] kunit: run kunit_tool from any directory
by Heidi Fahim
Implemented small fix so that the script changes work directories to the
root of the linux kernel source tree from which kunit.py is run. This
enables the user to run kunit from any working directory. Originally
considered using os.path.join but this is more error prone as we would
have to find all file path usages and modify them accordingly. Using
os.chdir ensures that the entire script is run within /linux.

[PATCH bpf-next 0/6] bpftool: Allow to select sections and filter probes
by Michal Rostecki
This patch series extend the "bpftool feature" subcommand with the
new positional arguments:
- "section", which allows to select a specific section of probes (i.e.
"system_config", "program_types", "map_types");
- "filter_in", which allows to select only probes which matches the
given regex pattern;
- "filter_out", which allows to filter out probes which do not match the
given regex pattern.
The main motivation behind those changes is ability the fact that some
probes (for example those related to "trace" or "write_user" helpers)
emit dmesg messages which might be confusing for people who are running
on production environments. For details see the Cilium issue[0].

[PATCH 0/2] ftrace/selftests: clean up failure cases
by Alan Maguire
When running the ftrace selftests, 2 failures and 6 unresolved
cases were observed. The failures can be avoided by setting
a sysctl prior to test execution (fixed in patch 1) and the
unresolved cases result from absence of testing modules which
are built based on CONFIG options being set and program
availability (fixed in patch 2).
These seem more like "unsupported" than "unresolved" errors,
since for the ftrace tests "unresolved" cases cause the test
(and thus kselftest) to report failure. With these changes
in place, the unresolved cases become unsupported and the
test failures disappear, resulting in the ftracetest program
exiting with "ok" status.

[PATCH v3 kunit-next 0/2] kunit: add debugfs representation to show results/run tests
by Alan Maguire
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
Changes since v2:
- updated kunit_status2str() to kunit_status_to_string() and made it
static inline in include/kunit/test.h (Brendan)
- added log string to struct kunit_suite and kunit_case, with log
pointer in struct kunit pointing at the case log. This allows us
to collect kunit_[err|info|warning]() messages at the same time
as we printk() them. This solves for the most part the sharing
of log messages between test execution and debugfs since we
just print the suite log (which contains the test suite preamble)
and the individual test logs. The only exception is the suite-level
status, which we cannot store in the suite log as it would mean
we'd print the suite and its status prior to the suite's results.
(Brendan, patch 1)
- dropped debugfs-based kunit run patch for now so as not to cause
problems with tests currently under development (Brendan)
- fixed doc issues with code block (Brendan, patch 3)
Changes since v1:
- trimmed unneeded include files in lib/kunit/debugfs.c (Greg)
- renamed global debugfs functions to be prefixed with kunit_ (Greg)
- removed error checking for debugfs operations (Greg)

arm64: bpf: Elide some moves to a0 after calls
by Palmer Dabbelt
There's four patches here, but only one of them actually does anything. The
first patch fixes a BPF selftests build failure on my machine and has already
been sent to the list separately. The next three are just staged such that
there are some patches that avoid changing any functionality pulled out from
the whole point of those refactorings, with two cleanups and then the idea.
Maybe this is an odd thing to say in a cover letter, but I'm not actually sure
this patch set is a good idea. The issue of extra moves after calls came up as
I was reviewing some unrelated performance optimizations to the RISC-V BPF JIT.
I figured I'd take a whack at performing the optimization in the context of the
arm64 port just to get a breath of fresh air, and I'm not convinced I like the
results.
That said, I think I would accept something like this for the RISC-V port
because we're already doing a multi-pass optimization for shrinking function
addresses so it's not as much extra complexity over there. If we do that we
should probably start puling some of this code into the shared BPF compiler,
but we're also opening the doors to more complicated BPF JIT optimizations.
Given that the BPF JIT appears to have been designed explicitly to be
simple/fast as opposed to perform complex optimization, I'm not sure this is a
sane way to move forward.
I figured I'd send the patch set out as more of a question than anything else.
Specifically:
* How should I go about measuring the performance of these sort of
optimizations? I'd like to balance the time it takes to run the JIT with the
time spent executing the program, but I don't have any feel for what real BPF
programs look like or have any benchmark suite to run. Is there something
out there this should be benchmarked against? (I'd also like to know that to
run those benchmarks on the RISC-V port.)
* Is this the sort of thing that makes sense in a BPF JIT? I guess I've just
realized I turned "review this patch" into a way bigger rabbit hole than I
really want to go down...
I worked on top of 5.4 for these, but trivially different versions of the
patches applied on Linus' master a few days ago when I tried. LMK if those
aren't sane places to start from over here, I'm new to both arm64 and BPF so I
might be a bit lost.

[PATCH v4 kunit-next 0/3] kunit: add debugfs representation to show results
by Alan Maguire
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
Changes since v3:
- added CONFIG_KUNIT_DEBUGFS to support conditional compilation of debugfs
representation, including string logging (Frank, patch 1)
- removed unneeded NULL check for test_case in kunit_suite_for_each_test_case()
(Frank, patch 1)
- added kunit log test to verify logging multiple strings works
(Frank, patch 2)
- rephrased description of results file (Frank, patch 3)
Changes since v2:
- updated kunit_status2str() to kunit_status_to_string() and made it
static inline in include/kunit/test.h (Brendan)
- added log string to struct kunit_suite and kunit_case, with log
pointer in struct kunit pointing at the case log. This allows us
to collect kunit_[err|info|warning]() messages at the same time
as we printk() them. This solves for the most part the sharing
of log messages between test execution and debugfs since we
just print the suite log (which contains the test suite preamble)
and the individual test logs. The only exception is the suite-level
status, which we cannot store in the suite log as it would mean
we'd print the suite and its status prior to the suite's results.
(Brendan, patch 1)
- dropped debugfs-based kunit run patch for now so as not to cause
problems with tests currently under development (Brendan)
- fixed doc issues with code block (Brendan, patch 3)
Changes since v1:
- trimmed unneeded include files in lib/kunit/debugfs.c (Greg)
- renamed global debugfs functions to be prefixed with kunit_ (Greg)
- removed error checking for debugfs operations (Greg)
Alan Maguire (3):
kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display
kunit: add log test
kunit: update documentation to describe debugfs representation

Remove some of the outmoded "Why KUnit" rationale, and move some
UML-specific information to the kunit_tool page. Also update the Getting
Started guide to mention running tests without the kunit_tool wrapper.

Thanks: I've added a note to the "Why KUnit" section which I think
better reflects both the UML is optional, and that it can be used both
with and without kunit_tool.
Changelog:
v3:
- Added a note that KUnit can be used with UML, both with and without
kunit_tool to replace the section moved to kunit_tool.
v2:
https://lore.kernel.org/linux-kselftest/f99a3d4d-ad65-5fd1-3407-db33f378b1f…
- Reinstated the "Why Kunit?" section, minus the comparison with other
testing frameworks (covered in the FAQ), and the description of UML.
- Moved the description of UML into to kunit_tool page.
- Tidied up the wording around how KUnit is built and run to make it
work
without the UML description.
v1:

==============
KUnit is a lightweight unit testing and mocking framework for the Linux kernel.
-These tests are able to be run locally on a developer's workstation without a VM
-or special hardware.
KUnit is heavily inspired by JUnit, Python's unittest.mock, and
Googletest/Googlemock for C++. KUnit provides facilities for defining unit test
cases, grouping related test cases into test suites, providing common
infrastructure for running tests, and much more.
+KUnit consists of a kernel component, which provides a set of macros for easily
+writing unit tests. Tests written against KUnit will run on kernel boot if
+built-in, or when loaded if built as a module. These tests write out results to
+the kernel log in `TAP <https://testanything.org/>`_ format.
+
+To make running these tests (and reading the results) easier, KUnit offsers
+:doc:`kunit_tool <kunit-tool>`, which builds a `User Mode Linux
+<http://user-mode-linux.sourceforge.net>`_ kernel, runs it, and parses the test
+results. This provides a quick way of running KUnit tests during development,

[RFC PATCH v1] pin_on_cpu: Introduce thread CPU pinning system call
by Mathieu Desnoyers
There is an important use-case which is not possible with the
"rseq" (Restartable Sequences) system call, which was left as
future work.
That use-case is to modify user-space per-cpu data structures
belonging to specific CPUs which may be brought offline and
online again by CPU hotplug. This can be used by memory
allocators to migrate free memory pools when CPUs are brought
offline, or by ring buffer consumers to target specific per-CPU
buffers, even when CPUs are brought offline.
A few rather complex prior attempts were made to solve this.
Those were based on in-kernel interpreters (cpu_opv, do_on_cpu).
That complexity was generally frowned upon, even by their author.
This patch fulfills this use-case in a refreshingly simple way:
it introduces a "pin_on_cpu" system call, which allows user-space
threads to pin themselves on a specific CPU (which needs to be
present in the thread's allowed cpu mask), and then clear this
pinned state.
"But this can already be done with sched_setaffinity", some
would rightfully reply. However, there is a significant twist
in the way pin_on_cpu deals with CPU hotplug compared to the
allowed cpu mask.
When all CPUs part of the thread's allowed cpu mask are offlined,
this mask is effectively reset to include all CPUs. This behavior
is completely incompatible with modifying per-cpu data structures:
the updates then become racy between concurrent CPUs trying to
update the given per-cpu data.
Conversely, all threads pinned on a given CPU with pin_on_cpu are
guaranteed to be scheduled on the same runqueue when that CPU is
offline. If that CPU is brought back online, the CPU hotplug
scheduler hooks are responsible for migrating back the tasks to
their pinned CPU.
For instance, this allows implementing this userspace library API
for incrementing a per-cpu counter for a specific cpu number
received as parameter:
static inline __attribute__((always_inline))
int percpu_addv(intptr_t *v, intptr_t count, int cpu)
{
int ret;
ret = rseq_addv(v, count, cpu);
check:
if (rseq_unlikely(ret)) {
pin_on_cpu_set(cpu);
ret = rseq_addv(v, count, percpu_current_cpu());
pin_on_cpu_clear();
goto check;
}
return 0;
}

[PATCH AUTOSEL 4.14 032/186] kselftest: Minimise dependency of get_size on C library interfaces
by Sasha Levin
From: Siddhesh Poyarekar <siddhesh(a)gotplt.org>
[ Upstream commit 6b64a650f0b2ae3940698f401732988699eecf7a ]
It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest. This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function. The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries. Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.
On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.
Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.
To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function. The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

[PATCH AUTOSEL 4.19 215/252] selftests: bpf: Reset global state between reuseport test runs
by Sasha Levin
From: Lorenz Bauer <lmb(a)cloudflare.com>
[ Upstream commit 51bad0f05616c43d6d34b0a19bcc9bdab8e8fb39 ]
Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.
Zero both after individual test runs, which fixes the mentioned false
positives.

[PATCH AUTOSEL 5.4 401/459] selftests/eeh: Bump EEH wait time to 60s
by Sasha Levin
From: Oliver O'Halloran <oohall(a)gmail.com>
[ Upstream commit 414f50434aa2463202a5b35e844f4125dd1a7101 ]
Some newer cards supported by aacraid can take up to 40s to recover
after an EEH event. This causes spurious failures in the basic EEH
self-test since the current maximim timeout is only 30s.
Fix the immediate issue by bumping the timeout to a default of 60s,
and allow the wait time to be specified via an environmental variable
(EEH_MAX_WAIT).

[PATCH AUTOSEL 5.4 397/459] selftests: bpf: Reset global state between reuseport test runs
by Sasha Levin
From: Lorenz Bauer <lmb(a)cloudflare.com>
[ Upstream commit 51bad0f05616c43d6d34b0a19bcc9bdab8e8fb39 ]
Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.
Zero both after individual test runs, which fixes the mentioned false
positives.

[PATCH AUTOSEL 5.4 183/459] selftests/net: make so_txtime more robust to timer variance
by Sasha Levin
From: Willem de Bruijn <willemb(a)google.com>
[ Upstream commit ea6a547669b37453f2b1a5d85188d75b3613dfaa ]
The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.
Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

[PATCH AUTOSEL 5.4 099/459] selftests: settings: tests can be in subsubdirs
by Sasha Levin
From: Matthieu Baerts <matthieu.baerts(a)tessares.net>
[ Upstream commit ac87813d4372f4c005264acbe3b7f00c1dee37c4 ]
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.
ok 1 selftests: net/mptcp: mptcp_connect.sh
Before we had:
ok 1 selftests: mptcp: mptcp_connect.sh
But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

[PATCH AUTOSEL 5.4 071/459] kselftest: Minimise dependency of get_size on C library interfaces
by Sasha Levin
From: Siddhesh Poyarekar <siddhesh(a)gotplt.org>
[ Upstream commit 6b64a650f0b2ae3940698f401732988699eecf7a ]
It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest. This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function. The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries. Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.
On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.
Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.
To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function. The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

[PATCH AUTOSEL 5.5 465/542] selftests/eeh: Bump EEH wait time to 60s
by Sasha Levin
From: Oliver O'Halloran <oohall(a)gmail.com>
[ Upstream commit 414f50434aa2463202a5b35e844f4125dd1a7101 ]
Some newer cards supported by aacraid can take up to 40s to recover
after an EEH event. This causes spurious failures in the basic EEH
self-test since the current maximim timeout is only 30s.
Fix the immediate issue by bumping the timeout to a default of 60s,
and allow the wait time to be specified via an environmental variable
(EEH_MAX_WAIT).

[PATCH AUTOSEL 5.5 461/542] selftests: bpf: Reset global state between reuseport test runs
by Sasha Levin
From: Lorenz Bauer <lmb(a)cloudflare.com>
[ Upstream commit 51bad0f05616c43d6d34b0a19bcc9bdab8e8fb39 ]
Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.
Zero both after individual test runs, which fixes the mentioned false
positives.

[PATCH AUTOSEL 5.5 310/542] kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds
by Sasha Levin
From: Alan Maguire <alan.maguire(a)oracle.com>
[ Upstream commit 1c024d45151b51c8f8d4749e65958b0bcf3e7c52 ]
In discussion of how to handle timeouts, it was noted that if
sysctl_hung_task_timeout_seconds is exceeded for a kunit test,
the test task will be killed and an oops generated. This should
suffice as a means of debugging such timeout issues for now.
Hence remove use of sysctl_hung_task_timeout_secs, which has the
added benefit of avoiding the need to export that symbol from
the core kernel.

[PATCH AUTOSEL 5.5 209/542] selftests/net: make so_txtime more robust to timer variance
by Sasha Levin
From: Willem de Bruijn <willemb(a)google.com>
[ Upstream commit ea6a547669b37453f2b1a5d85188d75b3613dfaa ]
The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.
Allow greater variance in a run and retry to further reduce flakiness.
Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.
In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

[PATCH AUTOSEL 5.5 115/542] selftests: settings: tests can be in subsubdirs
by Sasha Levin
From: Matthieu Baerts <matthieu.baerts(a)tessares.net>
[ Upstream commit ac87813d4372f4c005264acbe3b7f00c1dee37c4 ]
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.

[PATCH AUTOSEL 5.5 081/542] kselftest: Minimise dependency of get_size on C library interfaces
by Sasha Levin
From: Siddhesh Poyarekar <siddhesh(a)gotplt.org>
[ Upstream commit 6b64a650f0b2ae3940698f401732988699eecf7a ]
It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest. This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function. The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries. Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.
On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.
Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.
To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function. The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

[PATCH] selftests: use LDLIBS for libraries instead of LDFLAGS
by Dmitry Safonov
While building selftests, the following errors were observed:
> tools/testing/selftests/timens'
> gcc -Wall -Werror -pthread -lrt -ldl timens.c -o tools/testing/selftests/timens/timens
> /usr/bin/ld: /tmp/ccGy5CST.o: in function `check_config_posix_timers':
> timens.c:(.text+0x65a): undefined reference to `timer_create'
> collect2: error: ld returned 1 exit status
Quoting commit 870f193d48c2 ("selftests: net: use LDLIBS instead of
LDFLAGS"):
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
While at here, correct other selftests, not only timens ones.

Remove some of the outmoded "Why KUnit" rationale, and move some
UML-specific information to the kunit_tool page. Also update the Getting
Started guide to mention running tests without the kunit_tool wrapper.

Thanks for your comments. I've reinstated the "Why KUnit" section with
some minor changes.
Changes since v1[1]:
- Reinstated the "Why Kunit?" section, minus the comparison with other
testing frameworks (covered in the FAQ), and the description of UML.
- Moved the description of UML into to kunit_tool page.
- Tidied up the wording around how KUnit is built and run to make it work
without the UML description.

[PATCH 1/2] cgroup: allow deletion of cgroups containing only dying processes
by Suren Baghdasaryan
A cgroup containing only dying tasks will be seen as empty when a userspace
process reads its cgroup.procs or cgroup.tasks files. It should be safe to
delete such a cgroup as it is considered empty. However if one of the dying
tasks did not reach cgroup_exit then an attempt to delete the cgroup will
fail with EBUSY because cgroup_is_populated() will not consider it empty
until all tasks reach cgroup_exit. Such a condition can be triggered when
a task consumes large amounts of memory and spends enough time in exit_mm
to create delay between the moment it is flagged as PF_EXITING and the
moment it reaches cgroup_exit.
Fix this by detecting cgroups containing only dying tasks during cgroup
destruction and proceeding with it while postponing the final step of
releasing the last reference until the last task reaches cgroup_exit.

[PATCH v3 0/7] binfmt_elf: Update READ_IMPLIES_EXEC logic for modern CPUs
by Kees Cook
Hi,
This is a refresh of my earlier attempt to fix READ_IMPLIES_EXEC. I think
it incorporates the feedback from v2, and I've now added a selftest. This
series is for x86, arm, and arm64; I'd like it to go via -tip, though,
just to keep this change together with the selftest. To that end, I'd like
to collect Acks from the respective architecture maintainers. (Note that
most other architectures don't suffer from this problem. e.g. powerpc's
behavior appears to already be correct. MIPS may need adjusting but the
history of CPU features and toolchain behavior is very unclear to me.)
Repeating the commit log from later in the series:
The READ_IMPLIES_EXEC work-around was designed for old toolchains that
lacked the ELF PT_GNU_STACK marking under the assumption that toolchains
that couldn't specify executable permission flags for the stack may not
know how to do it correctly for any memory region.
This logic is sensible for having ancient binaries coexist in a system
with possibly NX memory, but was implemented in a way that equated having
a PT_GNU_STACK marked executable as being as "broken" as lacking the
PT_GNU_STACK marking entirely. Things like unmarked assembly and stack
trampolines may cause PT_GNU_STACK to need an executable bit, but they
do not imply all mappings must be executable.
This confusion has led to situations where modern programs with explicitly
marked executable stack are forced into the READ_IMPLIES_EXEC state when
no such thing is needed. (And leads to unexpected failures when mmap()ing
regions of device driver memory that wish to disallow VM_EXEC[1].)
In looking for other reasons for the READ_IMPLIES_EXEC behavior, Jann
Horn noted that glibc thread stacks have always been marked RWX (until
2003 when they started tracking the PT_GNU_STACK flag instead[2]). And
musl doesn't support executable stacks at all[3]. As such, no breakage
for multithreaded applications is expected from this change.

[RFC v1] xarray: start converting test_xarray to KUnit
by Brendan Higgins
xarray predates KUnit; however, it would be good to get all unit tests
in the kernel implemented using the same framework.
This initial conversion is a bit hacky as it doesn't switch everything
over to the KUnit semantics; however, it does break out the test cases
as KUnit test cases, and calls KUNIT_FAIL() when XA_BUG_ON() fails. So
the test does now take advantage of now reporting using the TAP format.
The reason I didn't convert everything over the KUnit semantics is that
I didn't want to get too far into this before getting some feedback from
Willy. I don't think there is anything I have made worse with the
changes I have made so far; this also at least serves as a starting
point.
TODO:
- Convert tests to use KUnit semantics.
- Figured out what to do with tools/testing/radix-tree/ xarray stuff.

[PATCH v11 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.
This is patch 1 of an 9 patch series.
Problem:
Currently tasks attempting to reserve 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 reserve more hugetlb memory than its
hugetlb_cgroup limit allows, the kernel will allow the mmap/shmget call, but
will SIGBUS the task when it attempts to fault in the excess memory.
We have users hitting their hugetlb_cgroup limits and thus we've been
looking at this failure mode. We'd like to improve this behavior such that users
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. This
gives the user an opportunity to fallback more gracefully to
non-hugetlbfs memory for example.
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.rsvd.[limit|usage|max_usage]_in_bytes'. This counter has
slightly different semantics than
'hugetlb.xMB.[limit|usage|max_usage]_in_bytes':
- While usage_in_bytes tracks all *faulted* hugetlb memory,
rsvd.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 rsvd.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.
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 rsvd.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 rsvd.limit_in_bytes concurrently,
and this approach gives them the option to do so.
Testing:
- Added tests passing.
- Used libhugetlbfs for regression testing.

Changes in v11:
- Renamed resv.* or 'reservation' or 'reserved' to rsvd.*
- Renamed hugetlb_cgroup_get_counter() to
hugetlb_cgroup_counter_from_cgroup().
Changes in v10:
- Renamed reservation_* to resv.*

[PATCH] Documentation: kunit: Make the KUnit documentation less UML-specific
by David Gow
Remove some of the outmoded "Why KUnit" rationale -- which focuses
significantly on UML -- and update the Getting Started guide to mention
running tests without the kunit_tool wrapper.
Signed-off-by: David Gow <davidgow(a)google.com>
---
This is an attempt at resolving some of the issues with the KUnit
documentation pointed out here:
https://lore.kernel.org/linux-kselftest/CABVgOSkiLi0UNijH1xTSvmsJEE5+ocCZ7n…
There's definitely room for further work on the KUnit documentation
(e.g., adding more information around the environment tests run in), but
this hopefully is better than nothing as a starting point.

@@ -17,63 +17,23 @@ What is KUnit?
==============
KUnit is a lightweight unit testing and mocking framework for the Linux kernel.
-These tests are able to be run locally on a developer's workstation without a VM
-or special hardware.
KUnit is heavily inspired by JUnit, Python's unittest.mock, and
Googletest/Googlemock for C++. KUnit provides facilities for defining unit test
cases, grouping related test cases into test suites, providing common
infrastructure for running tests, and much more.
-Get started now: :doc:`start`
-
-Why KUnit?
-==========
-
-A unit test is supposed to test a single unit of code in isolation, hence the
-name. A unit test should be the finest granularity of testing and as such should
-allow all possible code paths to be tested in the code under test; this is only
-possible if the code under test is very small and does not have any external
-dependencies outside of the test's control like hardware.
-
-Outside of KUnit, there are no testing frameworks currently
-available for the kernel that do not require installing the kernel on a test
-machine or in a VM and all require tests to be written in userspace running on
-the kernel; this is true for Autotest, and kselftest, disqualifying
-any of them from being considered unit testing frameworks.
+KUnit consists of a kernel component, which provides a set of macros for easily
+writing unit tests. Tests written against KUnit will run on kernel boot if
+built-in, or when loaded if built as a module. These tests write out results to
+the kernel log in `TAP <https://testanything.org/>`_ format.
-KUnit addresses the problem of being able to run tests without needing a virtual
-machine or actual hardware with User Mode Linux. User Mode Linux is a Linux
-architecture, like ARM or x86; however, unlike other architectures it compiles
-to a standalone program that can be run like any other program directly inside
-of a host operating system; to be clear, it does not require any virtualization
-support; it is just a regular program.
+To make running these tests (and reading the results) easier, KUnit offsers
+:doc:`kunit_tool <kunit-tool>`, which builds a `User Mode Linux
+<http://user-mode-linux.sourceforge.net>`_ kernel, runs it, and parses the test
+results. This provides a quick way of running KUnit tests during development.
-Alternatively, kunit and kunit tests can be built as modules and tests will
-run when the test module is loaded.
-
-KUnit is fast. Excluding build time, from invocation to completion KUnit can run
-several dozen tests in only 10 to 20 seconds; this might not sound like a big
-deal to some people, but having such fast and easy to run tests fundamentally
-changes the way you go about testing and even writing code in the first place.
-Linus himself said in his `git talk at Google
-<https://gist.github.com/lorn/1272686/revisions#diff-53c65572127855f1b003db4…>`_:
-
- "... a lot of people seem to think that performance is about doing the
- same thing, just doing it faster, and that is not true. That is not what
- performance is all about. If you can do something really fast, really
- well, people will start using it differently."
-
-In this context Linus was talking about branching and merging,
-but this point also applies to testing. If your tests are slow, unreliable, are
-difficult to write, and require a special setup or special hardware to run,
-then you wait a lot longer to write tests, and you wait a lot longer to run
-tests; this means that tests are likely to break, unlikely to test a lot of
-things, and are unlikely to be rerun once they pass. If your tests are really
-fast, you run them all the time, every time you make a change, and every time
-someone sends you some code. Why trust that someone ran all their tests
-correctly on every change when you can just run them yourself in less time than
-it takes to read their test log?

[RESEND PATCH v9 00/13] selftests/resctrl: Add resctrl selftest
by Fenghua Yu
[Resend the v9 patch set to Shuah Khan and linux-kselftest mailing list.
No code and commit message change.]
With more and more resctrl features are being added by Intel, AMD
and ARM, a test tool is becoming more and more useful to validate
that both hardware and software functionalities work as expected.
We introduce resctrl selftest to cover resctrl features on X86, AMD
and ARM architectures. It first implements MBM (Memory Bandwidth
Monitoring), MBA (Memory Bandwidth Allocation), L3 CAT (Cache Allocation
Technology), and CQM (Cache QoS Monitoring) tests. We will enhance
the selftest tool to include more functionality tests in the future.
The tool has been tested on Intel RDT, AMD QoS and ARM MPAM and is
in tools/testing/selftests/resctrl in order to have generic test code
base for all architectures.
The selftest tool we are introducing here provides a convenient
tool which does automatic resctrl testing, is easily available in kernel
tree, and covers Intel RDT, AMD QoS and ARM MPAM.
There is an existing resctrl test suite 'intel_cmt_cat'. But its major
purpose is to test Intel RDT hardware via writing and reading MSR
registers. It does access resctrl file system; but the functionalities
are very limited. And it doesn't support automatic test and a lot of
manual verifications are involved.
Changelog:
v9:
- Per Boris suggestion, add Co-developed-by in each patch to make it
clear who contributed to the patch set.
v8:
Update code per comments from Andre Przywara from ARM:
- Change Makefile and remove inline assembly code to build and test the
tool on ARM
- Change the output to TAP format because the format is both readable by
human and other test tools.
- Detect resctrl feature from /proc/cpuinfo instead of dmesg to support
generic detection on all architectures.
- Fix a few coding issues.
v7:
- Fix a few warnings when compiling patches separately, pointed by Babu
v6:
- Fix a benchmark reading optimized out issue in newer GCC.
- Fix a few coding style issues.
- Re-arrange code among patches to make cleaner code. No change in patches
structure.
v5:
- Based the v4 patches submitted by Fenghua Yu and added changes to support
AMD.
- Changed the function name get_sock_num to get_resource_id. Intel uses
socket number for schemata and AMD uses l3 index id. To generalize,
changed the function name to get_resource_id.
- Added the code to detect vendor.
- Disabled the few tests for AMD where the test results are not clear.
Also AMD does not have IMC.
- Fixed few compile issues.
- Some cleanup to make each patch independent.
- Tested the patches on AMD system. Fenghua, Need your help to test on
Intel box. Please feel free to change and resubmit if something
broken.
v4:
- address comments from Balu and Randy
- Add CAT and CQM tests
v3:
- Change code based on comments from Babu Moger
- Remove some unnessary code and use pipe to communicate b/w processes
v2:
- Change code based on comments from Babu Moger
- Clean up other places.

Changes since v4:
* Added documentation about the huge page behavior of the new
/proc/vmstat items.
* Added a missing mode_node_page_state() call to put_compound_head().
* Fixed a tracepoint call in page_ref_sub_return().
* Added a trailing underscore to a URL in pin_user_pages.rst, to fix
a broken generated link.
* Added ACKs and reviewed-by's from Jan Kara and Kirill Shutemov.
* Rebased onto today's linux.git, and
* I am experimenting here with "git format-patch --base=<commit>".
This generated the "base-commit:" tag you'll see at the end of this
cover letter. I was inspired to do so after trying out a new
get-lore-mbox.py tool (it's very nice), mentioned in a recent LWN
article (https://lwn.net/Articles/811528/ ). That tool relies on the
base-commit tag for some things.
============================================================
Changes since v3:
* Rebased onto latest linux.git
* Added ACKs and reviewed-by's from Kirill Shutemov and Jan Kara.
* /proc/vmstat:
* Renamed items, after realizing that I hate the previous names:
nr_foll_pin_requested --> nr_foll_pin_acquired
nr_foll_pin_returned --> nr_foll_pin_released
* Removed the CONFIG_DEBUG_VM guard, and collapsed away a wrapper
routine: now just calls mod_node_page_state() directly.
* Tweaked the WARN_ON_ONCE() statements in mm/hugetlb.c to be more
informative, and added comments above them as well.
* Fixed gup_benchmark: signed int --> unsigned long.
* One or two minor formatting changes.
============================================================
Changes since v2:
* Rebased onto linux.git, because the akpm tree for 5.6 has been merged.
* Split the tracking patch into even more patches, as requested.
* Merged Matthew Wilcox's dump_page() changes into mine, as part of the
first patch.
* Renamed: page_dma_pinned() --> page_maybe_dma_pinned(), in response to
Kirill Shutemov's review.
* Moved a WARN to the top of a routine, and fixed a typo in the commit
description of patch #7, also as suggested by Kirill.
============================================================
Changes since v1:
* Split the tracking patch into 6 smaller patches
* Rebased onto today's linux-next/akpm (there weren't any conflicts).
* Fixed an "unsigned int" vs. "int" problem in gup_benchmark, reported
by Nathan Chancellor. (I don't see it in my local builds, probably
because they use gcc, but an LLVM test found the mismatch.)
* Fixed a huge page pincount problem (add/subtract vs.
increment/decrement), spotted by Jan Kara.
============================================================
There is a reasonable case to be made for merging two of the patches
(patches 7 and 8), given that patch 7 provides tracking that has upper
limits on the number of pins that can be done with huge pages. Let me
know if anyone wants those merged, but unless there is some weird chance
of someone grabbing patch 7 and not patch 8, I don't really see the
need. Meanwhile, it's easier to review in this form.
Also, patch 3 has been revived. Earlier reviewers asked for it to be
merged into the tracking patch (one cannot please everyone, heh), but
now it's back out on it's own.
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
FOLL_PIN support is now in the main linux tree. However, the
patch to use FOLL_PIN to track pages was *not* submitted, because Leon
saw an RDMA test suite failure that involved (I think) page refcount
overflows when huge pages were used.
This patch definitively solves that kind of overflow problem, by adding
an exact pincount, for compound pages (of order > 1), in the 3rd struct
page of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1)
and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
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], [4] and in a remarkable number of email threads since about
2017. :)
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()
============================================================
Next steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
* Work with Ira and others to connect this all up with file system
leases.

[PATCH v26 12/22] 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 0/4] Implement FUTEX_WAIT_MULTIPLE operation
by André Almeida
Hello,
This patchset implements a new futex operation, called FUTEX_WAIT_MULTIPLE,
which allows a thread to wait on several futexes at the same time, and be
awoken by any of them.
The use case lies in the Wine implementation of the Windows NT interface
WaitMultipleObjects. This Windows API function allows a thread to sleep
waiting on the first of a set of event sources (mutexes, timers, signal,
console input, etc) to signal. Considering this is a primitive
synchronization operation for Windows applications, being able to quickly
signal events on the producer side, and quickly go to sleep on the
consumer side is essential for good performance of those running over Wine.
Since this API exposes a mechanism to wait on multiple objects, and
we might have multiple waiters for each of these events, a M->N
relationship, the current Linux interfaces fell short on performance
evaluation of large M,N scenarios. We experimented, for instance, with
eventfd, which has performance problems discussed below, but we also
experimented with userspace solutions, like making each consumer wait on
a condition variable guarding the entire list of objects, and then
waking up multiple variables on the producer side, but this is
prohibitively expensive since we either need to signal many condition
variables or share that condition variable among multiple waiters, and
then verify for the event being signaled in userspace, which means
dealing with often false positive wakes ups.
The natural interface to implement the behavior we want, also
considering that one of the waitable objects is a mutex itself, would be
the futex interface. Therefore, this patchset proposes a mechanism for
a thread to wait on multiple futexes at once, and wake up on the first
futex that was awaken.
In particular, using futexes in our Wine use case reduced the CPU
utilization by 4% for the game Beat Saber and by 1.5% for the game
Shadow of Tomb Raider, both running over Proton (a Wine based solution
for Windows emulation), when compared to the eventfd interface. This
implementation also doesn't rely of file descriptors, so it doesn't risk
overflowing the resource.
In time, we are also proposing modifications to glibc and libpthread to
make this feature available for Linux native multithreaded applications
using libpthread, which can benefit from the behavior of waiting on any
of a group of futexes.
Technically, the existing FUTEX_WAIT implementation can be easily
reworked by using futex_wait_multiple() with a count of one, and I
have a patch showing how it works. I'm not proposing it, since
futex is such a tricky code, that I'd be more comfortable to have
FUTEX_WAIT_MULTIPLE running upstream for a couple development cycles,
before considering modifying FUTEX_WAIT.
The patch series includes an extensive set of kselftests validating
the behavior of the interface. We also implemented support[1] on
Syzkaller and survived the fuzzy testing.
Finally, if you'd rather pull directly a branch with this set you can
find it here:
https://gitlab.collabora.com/tonyk/linux/commits/futex-dev
=== Performance of eventfd ===
Polling on several eventfd contexts with semaphore semantics would
provide us with the exact semantics we are looking for. However, as
shown below, in a scenario with sufficient producers and consumers, the
eventfd interface itself becomes a bottleneck, in particular because
each thread will compete to acquire a sequence of waitqueue locks for
each eventfd context in the poll list. In addition, in the uncontended
case, where the producer is ready for consumption, eventfd still
requires going into the kernel on the consumer side.
When a write or a read operation in an eventfd file succeeds, it will try
to wake up all threads that are waiting to perform some operation to
the file. The lock (ctx->wqh.lock) that hold the access to the file value
(ctx->count) is the same lock used to control access the waitqueue. When
all those those thread woke, they will compete to get this lock. Along
with that, the poll() also manipulates the waitqueue and need to hold
this same lock. This lock is specially hard to acquire when poll() calls
poll_freewait(), where it tries to free all waitqueues associated with
this poll. While doing that, it will compete with a lot of read and
write operations that have been waken.
In our use case, with a huge number of parallel reads, writes and polls,
this lock is a bottleneck and hurts the performance of applications. Our
implementation of futex, however, decrease the calls of spin lock by more
than 80% in some user applications.
Finally, eventfd operates on file descriptors, which is a limited
resource that has shown its limitation in our use cases. Despite the
Windows interface not waiting on more than 64 objects at once, we still
have multiple waiters at the same time, and we were easily able to
exhaust the FD limits on applications like games.
The RFC for this patch can be found here:

Thanks,
André

[PATCH] selftests: allow detection of build failures
by Jiri Benc
Commit 5f70bde26a48 ("selftests: fix build behaviour on targets' failures")
added a logic to track failure of builds of individual targets. However, it
does exactly the opposite of what a distro kernel needs: we create a RPM
package with a selected set of selftests and we need the build to fail if
build of any of the targets fail.
Both use cases are valid. A distribution kernel is in control of what is
included in the kernel and what is being built; any error needs to be
flagged and acted upon. A CI system that tries to build as many tests as
possible on the best effort basis is not really interested in a failure here
and there.
Support both use cases by introducing a FORCE_TARGETS variable. It is
switched off by default to make life for CI systems easier, distributions
can easily switch it on while building their packages.

[PATCH] selftests/vm: Add missed tests in run_vmtests
by sj38.park＠gmail.com
From: SeongJae Park <sjpark(a)amazon.de>
The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2],
and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and
thus the 'run_tests' command of kselftests doesn't run those. This
commit adds those in the script.
'gup_benchmark' and 'transhuge-stress' are also not included in the
'run_vmtests', but this commit does not add those because those are for
performance measurement rather than pass/fail tests.
[1] commit 26b4224d9961 ("selftests: expanding more mlock selftest")
[2] commit 91cbacc34512 ("tools/testing/selftests/vm/map_fixed_noreplace.c: add test for MAP_FIXED_NOREPLACE")
[3] commit fcc1f2d5dd34 ("selftests: add a test program for variable huge page sizes in mmap/shmget")

[PATCH] selftests: fix too long argument
by Jiri Benc
With some shells, the command construed for install of bpf selftests becomes
too large due to long list of files:
make[1]: execvp: /bin/sh: Argument list too long
make[1]: *** [../lib.mk:73: install] Error 127
Currently, each of the file lists is replicated three times in the command:
in the shell 'if' condition, in the 'echo' and in the 'rsync'. Reduce that
by one instance by using make conditionals and separate the echo and rsync
into two shell commands. (One would be inclined to just remove the '@' at
the beginning of the rsync command and let 'make' echo it by itself;
unfortunately, it appears that the '@' in the front of mkdir silences output
also for the following commands.)
Also, separate handling of each of the lists to its own shell command.
The semantics of the makefile is unchanged before and after the patch. The
ability of individual test directories to override INSTALL_RULE is retained.

git@github.com:johnhubbard/linux.git track_user_pages_v4
I'm particularly pleased that the /proc/vmstat items are now available
in all configurations, seeing as how I was looking (in vain) for that
information during a recent investigation of a remotely reported
problem.
============================================================
Changes since v3:
* Rebased onto latest linux.git
* Added ACKs and reviewed-by's from Kirill Shutemov and Jan Kara.
* /proc/vmstat:
* Renamed items, after realizing that I hate the previous names:
nr_foll_pin_requested --> nr_foll_pin_acquired
nr_foll_pin_returned --> nr_foll_pin_released
* Removed the CONFIG_DEBUG_VM guard, and collapsed away a wrapper
routine: now just calls mod_node_page_state() directly.
* Tweaked the WARN_ON_ONCE() statements in mm/hugetlb.c to be more
informative, and added comments above them as well.
* Fixed gup_benchmark: signed int --> unsigned long.
* One or two minor formatting changes.
============================================================
Changes since v2:
* Rebased onto linux.git, because the akpm tree for 5.6 has been merged.
* Split the tracking patch into even more patches, as requested.
* Merged Matthew Wilcox's dump_page() changes into mine, as part of the
first patch.
* Renamed: page_dma_pinned() --> page_maybe_dma_pinned(), in response to
Kirill Shutemov's review.
* Moved a WARN to the top of a routine, and fixed a typo in the commit
description of patch #7, also as suggested by Kirill.
============================================================
Changes since v1:
* Split the tracking patch into 6 smaller patches
* Rebased onto today's linux-next/akpm (there weren't any conflicts).
* Fixed an "unsigned int" vs. "int" problem in gup_benchmark, reported
by Nathan Chancellor. (I don't see it in my local builds, probably
because they use gcc, but an LLVM test found the mismatch.)
* Fixed a huge page pincount problem (add/subtract vs.
increment/decrement), spotted by Jan Kara.
============================================================
There is a reasonable case to be made for merging two of the patches
(patches 7 and 8), given that patch 7 provides tracking that has upper
limits on the number of pins that can be done with huge pages. Let me
know if anyone wants those merged, but unless there is some weird chance
of someone grabbing patch 7 and not patch 8, I don't really see the
need. Meanwhile, it's easier to review in this form.
Also, patch 3 has been revived. Earlier reviewers asked for it to be
merged into the tracking patch (one cannot please everyone, heh), but
now it's back out on it's own.
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
FOLL_PIN support is now in the main linux tree. However, the
patch to use FOLL_PIN to track pages was *not* submitted, because Leon
saw an RDMA test suite failure that involved (I think) page refcount
overflows when huge pages were used.
This patch definitively solves that kind of overflow problem, by adding
an exact pincount, for compound pages (of order > 1), in the 3rd struct
page of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1)
and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
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], [4] and in a remarkable number of email threads since about
2017. :)
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()
============================================================
Next steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
* Work with Ira and others to connect this all up with file system
leases.

[PATCH 1/3] kvm: mmu: Replace unsigned with unsigned int for PTE access
by Ben Gardon
There are several functions which pass an access permission mask for
SPTEs as an unsigned. This works, but checkpatch complains about it.
Switch the occurrences of unsigned to unsigned int to satisfy checkpatch.
No functional change expected.
Tested by running kvm-unit-tests on an Intel Haswell machine. This
commit introduced no new failures.

[PATCH v6 6/6] selftests/cgroup: add tests for cloning into cgroups
by Christian Brauner
Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

[PATCH v25 20/21] selftests/x86: Add vDSO selftest for SGX
by Jarkko Sakkinen
Expand the selftest by invoking the enclave by using
__vdso_sgx_enter_enclave() in addition to direct ENCLS[EENTER].

[PATCH v25 12/21] 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 v3 00/12] mm/gup: track FOLL_PIN pages
by John Hubbard
Matthew,
I've merged in your dump_page() ideas, and also factored things out
into a new __dump_tail_page() routine, in order to save a few
indentation levels, mainly.
Kirill, thanks for your review comments. I've applied them, and I think
splitting this up as you recommended really makes it a lot better, and
easier to spot problems.
============================================================
Changes since v2:
* Rebased onto linux.git, because the akpm tree for 5.6 has been merged.
* Split the tracking patch into even more patches, as requested.
* Merged Matthew Wilcox's dump_page() changes into mine, as part of the
first patch.
* Renamed: page_dma_pinned() --> page_maybe_dma_pinned(), in response to
Kirill Shutemov's review.
* Moved a WARN to the top of a routine, and fixed a typo in the commit
description of patch #7, also as suggested by Kirill.
============================================================
Changes since v1:
* Split the tracking patch into 6 smaller patches
* Rebased onto today's linux-next/akpm (there weren't any conflicts).
* Fixed an "unsigned int" vs. "int" problem in gup_benchmark, reported
by Nathan Chancellor. (I don't see it in my local builds, probably
because they use gcc, but an LLVM test found the mismatch.)
* Fixed a huge page pincount problem (add/subtract vs.
increment/decrement), spotted by Jan Kara.
============================================================
There is a reasonable case to be made for merging two of the patches
(patches 4 and 5), given that patch 4 provides tracking that has upper
limits on the number of pins that can be done with huge pages. Let me
know if anyone wants those merged, but unless there is some weird chance
of someone grabbing patch 4 and not patch 5, I don't really see the
need. Meanwhile, it's easier to review in this form.
Also, patch 3 has been revived. Earlier reviewers asked for it to be
merged into the tracking patch (one cannot please everyone, heh), but
now it's back out on it's own.
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
It is based on today's (Jan 28) linux-next (branch: akpm),
commit 280e9cb00b41 ("drivers/media/platform/sti/delta/delta-ipc.c: fix
read buffer overflow")
There is a git repo and branch, for convenience in reviewing:
git@github.com:johnhubbard/linux.git
track_user_pages_v2_linux-next_akpm_28Jan2020
FOLL_PIN support is (so far) in mmotm and linux-next. However, the
patch to use FOLL_PIN to track pages was *not* submitted, because Leon
saw an RDMA test suite failure that involved (I think) page refcount
overflows when huge pages were used.
This patch definitively solves that kind of overflow problem, by adding
an exact pincount, for compound pages (of order > 1), in the 3rd struct
page of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Here's the last reviewed version of the tracking patch (v11):
https://lore.kernel.org/r/20191216222537.491123-1-jhubbard@nvidia.com
Jan Kara had provided a reviewed-by tag for that, but I've had to remove
it (again) here, due to having changed the patch "a little bit", in
order to add the feature described above.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1)
and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
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], [4] and in a remarkable number of email threads since about
2017. :)
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()
============================================================
Next steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
* Work with Ira and others to connect this all up with file system
leases.

[PATCH v10 1/8] 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.
This is patch 1 of an 8 patch series.
Problem:
Currently tasks attempting to reserve 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 reserve 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 users hitting their hugetlb_cgroup limits and thus we've been
looking at this failure mode. We'd like to improve this behavior such that users
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. This
gives the user an opportunity to fallback more gracefully to
non-hugetlbfs memory for example.
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|max_usage]_in_bytes'. This counter has
slightly different semantics than
'hugetlb.xMB.[limit|usage|max_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.
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.
- Used libhugetlbfs for regression testing.

[PATCH 0/3] Fix reconnection latency caused by FIN/ACK handling race
by sjpark＠amazon.com
From: SeongJae Park <sjpark(a)amazon.de>
When closing a connection, the two acks that required to change closing
socket's status to FIN_WAIT_2 and then TIME_WAIT could be processed in
reverse order. This is possible in RSS disabled environments such as a
connection inside a host.
For example, expected state transitions and required packets for the
disconnection will be similar to below flow.
00 (Process A) (Process B)
01 ESTABLISHED ESTABLISHED
02 close()
03 FIN_WAIT_1
04 ---FIN-->
05 CLOSE_WAIT
06 <--ACK---
07 FIN_WAIT_2
08 <--FIN/ACK---
09 TIME_WAIT
10 ---ACK-->
11 LAST_ACK
12 CLOSED CLOSED
The acks in lines 6 and 8 are the acks. If the line 8 packet is
processed before the line 6 packet, it will be just ignored as it is not
a expected packet, and the later process of the line 6 packet will
change the status of Process A to FIN_WAIT_2, but as it has already
handled line 8 packet, it will not go to TIME_WAIT and thus will not
send the line 10 packet to Process B. Thus, Process B will left in
CLOSE_WAIT status, as below.
00 (Process A) (Process B)
01 ESTABLISHED ESTABLISHED
02 close()
03 FIN_WAIT_1
04 ---FIN-->
05 CLOSE_WAIT
06 (<--ACK---)
07 (<--FIN/ACK---)
08 (fired in right order)
09 <--FIN/ACK---
10 <--ACK---
11 (processed in reverse order)
12 FIN_WAIT_2
Later, if the Process B sends SYN to Process A for reconnection using
the same port, Process A will responds with an ACK for the last flow,
which has no increased sequence number. Thus, Process A will send RST,
wait for TIMEOUT_INIT (one second in default), and then try
reconnection. If reconnections are frequent, the one second latency
spikes can be a big problem. Below is a tcpdump results of the problem:
14.436259 IP 127.0.0.1.45150 > 127.0.0.1.4242: Flags [S], seq 2560603644
14.436266 IP 127.0.0.1.4242 > 127.0.0.1.45150: Flags [.], ack 5, win 512
14.436271 IP 127.0.0.1.45150 > 127.0.0.1.4242: Flags [R], seq 2541101298

[PATCH][RESEND] selftests/ftrace: Have pid filter test use instance flag
by Steven Rostedt
From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org>
While running the ftracetests, the pid filter test failed because the
instance "foo" existed, and it was using it to rerun the test under a
instance named foo. The collision caused the test to fail as the mkdir
failed as the name already existed.
As of commit b5b77be812de7 ("selftests: ftrace: Allow some tests to be run
in a tracing instance") all a selftest needs to do to be tested in an
instance is to set the "instance" flag. There's no reason a selftest needs
to create an instance to run its test in an instance directly.
Remove the open coded testing in an instance for the pid filter test and
have it set the "instance" flag instead.

[PATCH v2 0/8] mm/gup: track FOLL_PIN pages (follow on from v12)
by John Hubbard
OK, as requested, I've split the tracking patch into 6 smaller patches,
and it should be *much* easier to understand and review now.
============================================================
Changes since v1:
* Split the tracking patch into 6 smaller patches
* Rebased onto today's linux-next/akpm (there weren't any conflicts).
* Fixed an "unsigned int" vs. "int" problem in gup_benchmark, reported
by Nathan Chancellor. (I don't see it in my local builds, probably
because they use gcc, but an LLVM test found the mismatch.)
* Fixed a huge page pincount problem (add/subtract vs.
increment/decrement), spotted by Jan Kara.
============================================================
There is a reasonable case to be made for merging two of the patches
(patches 4 and 5), given that patch 4 provides tracking that has upper
limits on the number of pins that can be done with huge pages. Let me
know if anyone wants those merged, but unless there is some weird chance
of someone grabbing patch 4 and not patch 5, I don't really see the
need. Meanwhile, it's easier to review in this form.
Also, patch 3 has been revived. Earlier reviewers asked for it to be
merged into the tracking patch (one cannot please everyone, heh), but
now it's back out on it's own.
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
It is based on today's (Jan 28) linux-next (branch: akpm),
commit 280e9cb00b41 ("drivers/media/platform/sti/delta/delta-ipc.c: fix
read buffer overflow")
There is a git repo and branch, for convenience in reviewing:
git@github.com:johnhubbard/linux.git
track_user_pages_v2_linux-next_akpm_28Jan2020
FOLL_PIN support is (so far) in mmotm and linux-next. However, the
patch to use FOLL_PIN to track pages was *not* submitted, because Leon
saw an RDMA test suite failure that involved (I think) page refcount
overflows when huge pages were used.
This patch definitively solves that kind of overflow problem, by adding
an exact pincount, for compound pages (of order > 1), in the 3rd struct
page of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Here's the last reviewed version of the tracking patch (v11):
https://lore.kernel.org/r/20191216222537.491123-1-jhubbard@nvidia.com
Jan Kara had provided a reviewed-by tag for that, but I've had to remove
it (again) here, due to having changed the patch "a little bit", in
order to add the feature described above.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1)
and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
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], [4] and in a remarkable number of email threads since about
2017. :)
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()
============================================================
Next steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
* Work with Ira and others to connect this all up with file system
leases.

[PATCH v2 kunit-next 0/3] kunit: add debugfs representation to show results/run tests
by Alan Maguire
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
In addition, we provide a way to re-run the tests and show results via
/sys/kernel/debug/kunit/<testsuite>/run
Changes since v1:
- trimmed unneeded include files in lib/kunit/debugfs.c (Greg)
- renamed global debugfs functions to be prefixed with kunit_ (Greg)
- removed error checking for debugfs operations (Greg)
Alan Maguire (3):
kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display
kunit: add "run" debugfs file to run suites, display results
kunit: update documentation to describe debugfs representation

[PATCH v1 0/7] kunit: create a centralized executor to dispatch all KUnit tests
by Brendan Higgins
## TL;DR
This patchset adds a centralized executor to dispatch tests rather than
relying on late_initcall to schedule each test suite separately along
with a couple of new features that depend on it.
## What am I trying to do?
Conceptually, I am trying to provide a mechanism by which test suites
can be grouped together so that they can be reasoned about collectively.
The last two of three patches in this series add features which depend
on this:
PATCH 5/7 Prints out a test plan right before KUnit tests are run[1];
this is valuable because it makes it possible for a test
harness to detect whether the number of tests run matches the
number of tests expected to be run, ensuring that no tests
silently failed.
PATCH 6/7 Add a new kernel command-line option which allows the user to
specify that the kernel poweroff, halt, or reboot after
completing all KUnit tests; this is very handy for running
KUnit tests on UML or a VM so that the UML/VM process exits
cleanly immediately after running all tests without needing a
special initramfs.
In addition, by dispatching tests from a single location, we can
guarantee that all KUnit tests run after late_init is complete, which
was a concern during the initial KUnit patchset review (this has not
been a problem in practice, but resolving with certainty is nevertheless
desirable).
Other use cases for this exist, but the above features should provide an
idea of the value that this could provide.

[PATCH v16 00/23] selftests, powerpc, x86: Memory Protection Keys
by Sandipan Das
Memory protection keys enables an application to protect its address
space from inadvertent access by its own code.
This feature is now enabled on powerpc and has been available since
4.16-rc1. The patches move the selftests to arch neutral directory
and enhance their test coverage.
Tested on powerpc64 and x86_64 (Skylake-SP).
Link to development branch:
https://github.com/sandip4n/linux/tree/pkey-selftests
Changelog
---------
Link to previous version (v16):
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=153824
v17:
(1) Fixed issues with i386 builds when running on x86_64
based on feedback from Dave.
(2) Replaced patch 6 from previous version with patch 7.
This addresses u64 format specifier related concerns
that Michael had raised in v15.
v16:
(1) Rebased on top of latest master.
(2) Switched to u64 instead of using an arch-dependent
pkey_reg_t type for references to the pkey register
based on suggestions from Dave, Michal and Michael.
(3) Removed build time determination of page size based
on suggestion from Michael.
(4) Fixed comment before the definition of __page_o_noops()
from patch 13 ("selftests/vm/pkeys: Introduce powerpc
support").
v15:
(1) Rebased on top of latest master.
(2) Addressed review comments from Dave Hansen.
(3) Moved code for getting or setting pkey bits to new
helpers. These changes replace patch 7 of v14.
(4) Added a fix which ensures that the correct count of
reserved keys is used across different platforms.
(5) Added a fix which ensures that the correct page size
is used as powerpc supports both 4K and 64K pages.
v14:
(1) Incorporated another round of comments from Dave Hansen.
v13:
(1) Incorporated comments for Dave Hansen.
(2) Added one more test for correct pkey-0 behavior.
v12:
(1) Fixed the offset of pkey field in the siginfo structure for
x86_64 and powerpc. And tries to use the actual field
if the headers have it defined.
v11:
(1) Fixed a deadlock in the ptrace testcase.
v10 and prior:
(1) Moved the testcase to arch neutral directory.
(2) Split the changes into incremental patches.

[PATCH 0/3] mm/gup: track FOLL_PIN pages (follow on from v12)
by John Hubbard
Leon Romanovsky:
If you get a chance, I'd love to have this short series (or even just
the first patch; the others are just selftests) run through your test
suite that was previously choking on my earlier v11 patchset. The huge
page pincount limitations are removed, so I'm expecting a perfect test
run this time!
Everyone:
This activates tracking of FOLL_PIN pages. This is in support of fixing
the get_user_pages()+DMA problem described in [1]-[4].
It is based on today's (Jan 24) mmotm. There is a git repo and branch,
for convenience in reviewing:
git@github.com:johnhubbard/linux.git track_user_pages_v1_mmotm_24Jan2020
FOLL_PIN support is (so far) in mmotm and linux-next. However, the
patch to use FOLL_PIN to track pages was *not* submitted, because Leon
saw an RDMA test suite failure that involved (I think) page refcount
overflows when huge pages were used.
This patch definitively solves that kind of overflow problem, by adding
an exact pincount, for compound pages (of order > 1), in the 3rd struct
page of a compound page. If available, that form of pincounting is used,
instead of the GUP_PIN_COUNTING_BIAS approach. Thanks again to Jan Kara
for that idea.
Here's the last reviewed version of the tracking patch (v11):
https://lore.kernel.org/r/20191216222537.491123-1-jhubbard@nvidia.com
Jan Kara had provided a reviewed-by tag for that, but I've had to remove
it (again) here, due to having changed the patch "a little bit", in
order to add the feature described above.
Other interesting changes:
* dump_page(): added one, or two new things to report for compound
pages: head refcount (for all compound pages), and map_pincount (for
compound pages of order > 1).
* Documentation/core-api/pin_user_pages.rst: removed the "TODO" for the
huge page refcount upper limit problems, and added notes about how it
works now. Also added a note about the dump_page() enhancements.
* Added some comments in gup.c and mm.h, to explain that there are two
ways to count pinned pages: exact (for compound pages of order > 1)
and fuzzy (GUP_PIN_COUNTING_BIAS: for all other pages).
============================================================
General notes about the tracking patch:
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], [4] and in a remarkable number of email threads since about
2017. :)
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()
============================================================
Next steps:
* Convert more subsystems from get_user_pages() to pin_user_pages().
* Work with Ira and others to connect this all up with file system
leases.

Hi Sven,
Did you run getmaintainers of this patch? You didn't send this to my

[PATCH v4] selftests/ftrace: fix glob selftest
by Sven Schnelle
test.d/ftrace/func-filter-glob.tc is failing on s390 because it has
ARCH_INLINE_SPIN_LOCK and friends set to 'y'. So the usual
__raw_spin_lock symbol isn't in the ftrace function list. Change
'*aw*lock' to '*spin*lock' which would hopefully match some of the
locking functions on all platforms.

[PATCH] selftests: settings: tests can be in subsubdirs
by Matthieu Baerts
Commit 852c8cbf34d3 (selftests/kselftest/runner.sh: Add 45 second
timeout per test) adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.

[PATCH v4 00/10] Create a userfaultfd demand paging test
by Ben Gardon
When handling page faults for many vCPUs during demand paging, KVM's MMU
lock becomes highly contended. This series creates a test with a naive
userfaultfd based demand paging implementation to demonstrate that
contention. This test serves both as a functional test of userfaultfd
and a microbenchmark of demand paging performance with a variable number
of vCPUs and memory per vCPU.
The test creates N userfaultfd threads, N vCPUs, and a region of memory
with M pages per vCPU. The N userfaultfd polling threads are each set up
to serve faults on a region of memory corresponding to one of the vCPUs.
Each of the vCPUs is then started, and touches each page of its disjoint
memory region, sequentially. In response to faults, the userfaultfd
threads copy a static buffer into the guest's memory. This creates a
worst case for MMU lock contention as we have removed most of the
contention between the userfaultfd threads and there is no time required
to fetch the contents of guest memory.
This test was run successfully on Intel Haswell, Broadwell, and
Cascadelake hosts with a variety of vCPU counts and memory sizes.
This test was adapted from the dirty_log_test.
The series can also be viewed in Gerrit here:
https://linux-review.googlesource.com/c/virt/kvm/kvm/+/1464
(Thanks to Dmitry Vyukov <dvyukov(a)google.com> for setting up the Gerrit
instance)
v4 (Responding to feedback from Andrew Jones, Peter Xu, and Peter Shier):
- Tested this revision by running
demand_paging_test
at each commit in the series on an Intel Haswell machine. Ran
demand_paging_test -u -v 8 -b 8M -d 10
on the same machine at the last commit in the series.
- Readded partial aarch64 support, though aarch64 and s390 remain
untested
- Implemented pipefd polling to reduce UFFD thread exit latency
- Added variable unit input for memory size so users can pass command
line arguments of the form -b 24M instead of the raw number or bytes
- Moved a missing break from a patch later in the series to an earlier
one
- Moved to syncing per-vCPU global variables to guest and looking up
per-vcpu arguments based on a single CPU ID passed to each guest
vCPU. This allows for future patches to pass more than the supported
number of arguments for each arch to the vCPUs.
- Implemented vcpu_args_set for s390 and aarch64 [UNTESTED]
- Changed vm_create to always allocate memslot 0 at 4G instead of only
when the number of pages required is large.
- Changed vcpu_wss to vcpu_memory_size for clarity.

[PATCH] selftests/bpf: Elide a check for LLVM versions that can't compile it
by Palmer Dabbelt
The current stable LLVM BPF backend fails to compile the BPF selftests
due to a compiler bug. The bug has been fixed in trunk, but that fix
hasn't landed in the binary packages I'm using yet (Fedora arm64).
Without this workaround the tests don't compile for me.
This patch triggers a preprocessor warning on LLVM versions that
definitely have the bug. The test may be conservative (ie, I'm not sure
if 9.1 will have the fix), but it should at least make the current set
of stable releases work together.
See https://reviews.llvm.org/D69438 for more information on the fix. I
obtained the workaround from
https://lore.kernel.org/linux-kselftest/aed8eda7-df20-069b-ea14-f0662898456…

[PATCH] Fix linked-list KUnit test when run multiple times
by David Gow
A few of the lists used in the linked-list KUnit tests (the
for_each_entry{,_reverse} tests) are declared 'static', and so are
not-reinitialised if the test runs multiple times. This was not a
problem when KUnit tests were run once on startup, but when tests are
able to be run manually (e.g. from debugfs[1]), this is no longer the
case.
Making these lists no longer 'static' causes the lists to be
reinitialised, and the test passes each time it is run. While there may
be some value in testing that initialising static lists works, the
for_each_entry_* tests are unlikely to be the right place for it.

[PATCH bpf-next] bpf: add bpf_ct_lookup_{tcp,udp}() helpers
by Matthew Cover
Allow looking up an nf_conn. This allows eBPF programs to leverage
nf_conntrack state for similar purposes to socket state use cases,
as provided by the socket lookup helpers. This is particularly
useful when nf_conntrack state is locally available, but socket
state is not.

[PATCH kunit 0/3] kunit: add debugfs representation to show results/run tests
by Alan Maguire
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
In addition, we provide a way to re-run the tests and show results via
/sys/kernel/debug/kunit/<testsuite>/run
Alan Maguire (3):
kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display
kunit: add "run" debugfs file to run suites, display results
kunit: update documentation to describe debugfs representation

[PATCH v9 1/8] 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.
This is patch 1 of an 8 patch series.
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.

[PATCH 1/3] selftests/x86: Build with LDFLAGS and LDLIBS
by Daniel Díaz
During cross-compilation, it was discovered that LDFLAGS and
LDLIBS were not being used while building binaries, leading
to defaults which were not necessarily correct.
OpenEmbedded reported this kind of problem:
ERROR: QA Issue: No GNU_HASH in the ELF binary [...], didn't pass LDFLAGS?

Re: [RFC PATCH v1] pin_on_cpu: Introduce thread CPU pinning system call

Indeed, this is not what this system call is trying to solve. Does the name "pin_on_cpu" lead
to confusion here ?
I thought that cgroups was already the mechanism taking care of this kind of requirement.
Thanks,
Mathieu

Re: [RFC PATCH v1] pin_on_cpu: Introduce thread CPU pinning system call
by Jan Ziak
Hello
I would like to note that this does not help userspace to express
dynamic scheduling relationships among processes/threads such as "do
not run processes A and B on the same core" or "run processes A and B
on cores sharing the same L2 cache".
Sincerely

[PATCH v5 6/6] selftests/cgroup: add tests for cloning into cgroups
by Christian Brauner
Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

[PATCH bpf-next v5 00/11] tools: Use consistent libbpf include paths everywhere
by Toke Høiland-Jørgensen
We are currently being somewhat inconsistent with the libbpf include paths,
which makes it difficult to move files from the kernel into an external
libbpf-using project without adjusting include paths.
Having the bpf/ subdir of $INCLUDEDIR in the include path has never been a
requirement for building against libbpf before, and indeed the libbpf pkg-config
file doesn't include it. So let's make all libbpf includes across the kernel
tree use the bpf/ prefix in their includes. Since bpftool skeleton generation
emits code with a libbpf include, this also ensures that those can be used in
existing external projects using the regular pkg-config include path.
This turns out to be a somewhat invasive change in the number of files touched;
however, the actual changes to files are fairly trivial (most of them are simply
made with 'sed'). The series is split to make the change for one tool subdir at
a time, while trying not to break the build along the way. It is structured like
this:
- Patch 1-3: Trivial fixes to Makefiles for issues I discovered while changing
the include paths.
- Patch 4-8: Change the include directives to use the bpf/ prefix, and updates
Makefiles to make sure tools/lib/ is part of the include path, but without
removing tools/lib/bpf
- Patch 9-11: Remove tools/lib/bpf from include paths to make sure we don't
inadvertently re-introduce includes without the bpf/ prefix.
Changelog:
v5:
- Combine the libbpf build rules in selftests Makefile (using Andrii's
suggestion for a make rule).
- Re-use self-tests libbpf build for runqslower (new patch 10)
- Formatting fixes
v4:
- Move runqslower error on missing BTF into make rule
- Make sure we don't always force a rebuild selftests
- Rebase on latest bpf-next (dropping patch 11)
v3:
- Don't add the kernel build dir to the runqslower Makefile, pass it in from
selftests instead.
- Use libbpf's 'make install_headers' in selftests instead of trying to
generate bpf_helper_defs.h in-place (to also work on read-only filesystems).
- Use a scratch builddir for both libbpf and bpftool when building in selftests.
- Revert bpf_helpers.h to quoted include instead of angled include with a bpf/
prefix.
- Fix a few style nits from Andrii
v2:
- Do a full cleanup of libbpf includes instead of just changing the
bpf_helper_defs.h include.

Changelog:
v4:
- Move runqslower error on missing BTF into make rule
- Make sure we don't always force a rebuild selftests
- Rebase on latest bpf-next (dropping patch 11)
v3:
- Don't add the kernel build dir to the runqslower Makefile, pass it in from
selftests instead.
- Use libbpf's 'make install_headers' in selftests instead of trying to
generate bpf_helper_defs.h in-place (to also work on read-only filesystems).
- Use a scratch builddir for both libbpf and bpftool when building in selftests.
- Revert bpf_helpers.h to quoted include instead of angled include with a bpf/
prefix.
- Fix a few style nits from Andrii
v2:
- Do a full cleanup of libbpf includes instead of just changing the
bpf_helper_defs.h include.

[PATCH v3 0/2] openat2: minor uapi cleanups
by Aleksa Sarai
Patch changelog:
v3:
* Merge changes into the original patches to make Al's life easier.
[Al Viro]
v2:
* Add include <linux/types.h> to openat2.h. [Florian Weimer]
* Move OPEN_HOW_SIZE_* constants out of UAPI. [Florian Weimer]
* Switch from __aligned_u64 to __u64 since it isn't necessary.
[David Laight]
v1: <https://lore.kernel.org/lkml/20191219105533.12508-1-cyphar@cyphar.com/>
While openat2(2) is still not yet in Linus's tree, we can take this
opportunity to iron out some small warts that weren't noticed earlier:
* A fix was suggested by Florian Weimer, to separate the openat2
definitions so glibc can use the header directly. I've put the
maintainership under VFS but let me know if you'd prefer it belong
ot the fcntl folks.
* Having heterogenous field sizes in an extensible struct results in
"padding hole" problems when adding new fields (in addition the
correct error to use for non-zero padding isn't entirely clear ).
The simplest solution is to just copy clone(3)'s model -- always use
u64s. It will waste a little more space in the struct, but it
removes a possible future headache.
This patch is intended to replace the corresponding patches in Al's
#work.openat2 tree (and *will not* apply on Linus' tree).
@Al: I will send some additional patches later, but they will require
proper design review since they're ABI-related features (namely,
adding a way to check what features a syscall supports as I
outlined in my talk here[1]).

[PATCH v16 00/23] selftests, powerpc, x86: Memory Protection Keys
by Sandipan Das
Memory protection keys enables an application to protect its address
space from inadvertent access by its own code.
This feature is now enabled on powerpc and has been available since
4.16-rc1. The patches move the selftests to arch neutral directory
and enhance their test coverage.
Tested on powerpc64 and x86_64 (Skylake-SP).
Changelog
---------
Link to previous version (v15):
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=149238
v16:
(1) Rebased on top of latest master.
(2) Switched to u64 instead of using an arch-dependent
pkey_reg_t type for references to the pkey register
based on suggestions from Dave, Michal and Michael.
(3) Removed build time determination of page size based
on suggestion from Michael.
(4) Fixed comment before the definition of __page_o_noops()
from patch 13 ("selftests/vm/pkeys: Introduce powerpc
support").
v15:
(1) Rebased on top of latest master.
(2) Addressed review comments from Dave Hansen.
(3) Moved code for getting or setting pkey bits to new
helpers. These changes replace patch 7 of v14.
(4) Added a fix which ensures that the correct count of
reserved keys is used across different platforms.
(5) Added a fix which ensures that the correct page size
is used as powerpc supports both 4K and 64K pages.
v14:
(1) Incorporated another round of comments from Dave Hansen.
v13:
(1) Incorporated comments for Dave Hansen.
(2) Added one more test for correct pkey-0 behavior.
v12:
(1) Fixed the offset of pkey field in the siginfo structure for
x86_64 and powerpc. And tries to use the actual field
if the headers have it defined.
v11:
(1) Fixed a deadlock in the ptrace testcase.
v10 and prior:
(1) Moved the testcase to arch neutral directory.
(2) Split the changes into incremental patches.

[PATCH v4 6/6] selftests/cgroup: add tests for cloning into cgroups
by Christian Brauner
Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

[PATCH bpf-next v3 00/11] tools: Use consistent libbpf include paths everywhere
by Toke Høiland-Jørgensen
The recent commit 6910d7d3867a ("selftests/bpf: Ensure bpf_helper_defs.h are
taken from selftests dir") broke compilation against libbpf if it is installed
on the system, and $INCLUDEDIR/bpf is not in the include path.
Since having the bpf/ subdir of $INCLUDEDIR in the include path has never been a
requirement for building against libbpf before, this needs to be fixed. One
option is to just revert the offending commit and figure out a different way to
achieve what it aims for. However, this series takes a different approach:
Changing all in-tree users of libbpf to consistently use a bpf/ prefix in
#include directives for header files from libbpf.
This turns out to be a somewhat invasive change in the number of files touched;
however, the actual changes to files are fairly trivial (most of them are simply
made with 'sed'). Also, this approach has the advantage that it makes external
and internal users consistent with each other, and ensures no future changes
breaks things in the same way as the commit referenced above.
The series is split to make the change for one tool subdir at a time, while
trying not to break the build along the way. It is structured like this:
- Patch 1-3: Trivial fixes to Makefiles for issues I discovered while changing
the include paths.
- Patch 4-8: Change the include directives to use the bpf/ prefix, and updates
Makefiles to make sure tools/lib/ is part of the include path, but without
removing tools/lib/bpf
- Patch 9-10: Remove tools/lib/bpf from include paths to make sure we don't
inadvertently re-introduce includes without the bpf/ prefix.
- Patch 11: Change the bpf_helpers.h file in libbpf itself back to using a quoted
include for bpf_helper_defs.h (the original source of breakage).
Changelog:
v3:
- Don't add the kernel build dir to the runqslower Makefile, pass it in from
selftests instead.
- Use libbpf's 'make install_headers' in selftests instead of trying to
generate bpf_helper_defs.h in-place (to also work on read-only filesystems).
- Use a scratch builddir for both libbpf and bpftool when building in selftests.
- Revert bpf_helpers.h to quoted include instead of angled include with a bpf/
prefix.
- Fix a few style nits from Andrii
v2:
- Do a full cleanup of libbpf includes instead of just changing the
bpf_helper_defs.h include.

[PATCH] kselftest: Minimise dependency of get_size on C library interfaces
by Siddhesh Poyarekar
It was observed[1] on arm64 that __builtin_strlen led to an infinite
loop in the get_size selftest. This is because __builtin_strlen (and
other builtins) may sometimes result in a call to the C library
function. The C library implementation of strlen uses an IFUNC
resolver to load the most efficient strlen implementation for the
underlying machine and hence has a PLT indirection even for static
binaries. Because this binary avoids the C library startup routines,
the PLT initialization never happens and hence the program gets stuck
in an infinite loop.
On x86_64 the __builtin_strlen just happens to expand inline and avoid
the call but that is not always guaranteed.
Further, while testing on x86_64 (Fedora 31), it was observed that the
test also failed with a segfault inside write() because the generated
code for the write function in glibc seems to access TLS before the
syscall (probably due to the cancellation point check) and fails
because TLS is not initialised.
To mitigate these problems, this patch reduces the interface with the
C library to just the syscall function. The syscall function still
sets errno on failure, which is undesirable but for now it only
affects cases where syscalls fail.

[PATCH v3 5/5] selftests/cgroup: add tests for cloning into cgroups
by Christian Brauner
Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

[PATCH v12 00/22] mm/gup: prereqs to track dma-pinned pages: FOLL_PIN
by John Hubbard
Hi,
The "track FOLL_PIN pages" would have been the very next patch, but it is
not included here because I'm still debugging a bug report from Leon.
Let's get all of the prerequisite work (it's been reviewed) into the tree
so that future reviews are easier. It's clear that any fixes that are
required to the tracking patch, won't affect these patches here.
This implements an API naming change (put_user_page*() -->
unpin_user_page*()), and also adds FOLL_PIN page support, up to
*but not including* actually tracking FOLL_PIN pages. It extends
the FOLL_PIN support to a few select subsystems. More subsystems will
be added in follow up work.
Christoph Hellwig, a point 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").
Changes since v11: Fixes resulting from Kirill Shutemov's review, plus
a fix for a kbuild robot-reported warning.
* Only include the first 22 patches: up to, but not including, the "track
FOLL_PIN pages" patch.
* Improved the efficiency of put_compound_head(), by avoiding get_page()
entirely, and instead doing the mass subtraction on one less than
refs, followed by a final put_page().
* Got rid of the forward declaration of __gup_longterm_locked(), by
moving get_user_pages_remote() further down in gup.c
* Got rid of a redundant page_is_devmap_managed() call, and simplified
put_devmap_managed_page() as part of that small cleanup.
* Changed put_devmap_managed_page() to do an early out if the page is
not devmap managed. This saves an indentation level.
* Applied the same type of change to __unpin_devmap_managed_user_page(),
which has the same checks.
* Changed release_pages() to handle the changed put_devmap_managed_page()
API.
* Removed EXPORT_SYMBOL(free_devmap_managed_page), as it is not required,
after the other refactoring.
* Fixed a kbuild robot sparse warning: added "static" to
try_pin_compound_head()'s declaration.
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
v11, which is here:
https://lore.kernel.org/r/20191216222537.491123-1-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 rdma-core tests: rdma-core/build/bin/run_tests.py
* 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 AUTOSEL 4.14 165/371] selftests/ipc: Fix msgque compiler warnings
by Sasha Levin
From: Kees Cook <keescook(a)chromium.org>
[ Upstream commit a147faa96f832f76e772b1e448e94ea84c774081 ]
This fixes the various compiler warnings when building the msgque
selftest. The primary change is using sys/msg.h instead of linux/msg.h
directly to gain the API declarations.
Fixes: 3a665531a3b7 ("selftests: IPC message queue copy feature test")

[PATCH bpf-next v2 00/10] tools: Use consistent libbpf include paths everywhere
by Toke Høiland-Jørgensen
The recent commit 6910d7d3867a ("selftests/bpf: Ensure bpf_helper_defs.h are
taken from selftests dir") broke compilation against libbpf if it is installed
on the system, and $INCLUDEDIR/bpf is not in the include path.
Since having the bpf/ subdir of $INCLUDEDIR in the include path has never been a
requirement for building against libbpf before, this needs to be fixed. One
option is to just revert the offending commit and figure out a different way to
achieve what it aims for. However, this series takes a different approach:
Changing all in-tree users of libbpf to consistently use a bpf/ prefix in
#include directives for header files from libbpf.
This turns out to be a somewhat invasive change in the number of files touched;
however, the actual changes to files are fairly trivial (most of them are simply
made with 'sed'). Also, this approach has the advantage that it makes external
and internal users consistent with each other, and ensures no future changes
breaks things in the same way as the commit referenced above.
The series is split to make the change for one tool subdir at a time, while
trying not to break the build along the way. It is structured like this:
- Patch 1-2: Trivial fixes to Makefiles for issues I discovered while changing
the include paths.
- Patch 3-7: Change the include directives to use the bpf/ prefix, and updates
Makefiles to make sure tools/lib/ is part of the include path, but without
removing tools/lib/bpf
- Patch 8: Change the bpf_helpers file in libbpf itself to use the bpf/ prefix
when including (the original source of breakage).
- Patch 9-10: Remove tools/lib/bpf from include paths to make sure we don't
inadvertently re-introduce includes without the bpf/ prefix.

[PATCH AUTOSEL 4.19 302/671] selftests/ipc: Fix msgque compiler warnings
by Sasha Levin
From: Kees Cook <keescook(a)chromium.org>
[ Upstream commit a147faa96f832f76e772b1e448e94ea84c774081 ]
This fixes the various compiler warnings when building the msgque
selftest. The primary change is using sys/msg.h instead of linux/msg.h
directly to gain the API declarations.
Fixes: 3a665531a3b7 ("selftests: IPC message queue copy feature test")

[PATCH AUTOSEL 5.4 155/205] 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

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

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)

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)

0000000000000000 test_pkt_access:

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 5.4 132/205] kselftests: cgroup: Avoid the reuse of fd after it is deallocated
by Sasha Levin
From: Hewenliang <hewenliang4(a)huawei.com>
[ Upstream commit d671fa6393d6788fc65555d4643b71cb3a361f36 ]
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.

[PATCH AUTOSEL 5.4 116/205] selftests: gen_kselftest_tar.sh: Do not clobber kselftest/
by Sasha Levin
From: Kees Cook <keescook(a)chromium.org>
[ Upstream commit ea1bf0bb18c0bd627d7b551196453ff2fff44225 ]
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.

[PATCH v5 0/2] mm/hmm/test: add self tests for HMM
by Ralph Campbell
This series adds basic self tests for HMM and mmu interval notifiers so
that changes can be validated. It is based on linux-5.5.0-rc1 and is for
Jason's rdma/hmm tree since I believe he is planning some interval
notifier changes. Patch 2 was last posted as part of [1] but the other
patches in that series have been merged and this version of the HMM tests
is modified to address Jason's concern over using both process wide MMU
notifiers in combination with MMU interval notifiers. Therefore, patch 1
adds some core functionality to allow intervals to be updated from within
the invalidation() callback so that MMU_NOTIFY_UNMAP events can update
the range being tracked.

[PATCH v15 00/24] selftests, powerpc, x86: Memory Protection Keys
by Sandipan Das
Memory protection keys enables an application to protect its address
space from inadvertent access by its own code.
This feature is now enabled on powerpc and has been available since
4.16-rc1. The patches move the selftests to arch neutral directory
and enhance their test coverage.
Testing
-------
Verified for correctness on powerpc. Need help with x86 testing as I
do not have access to a Skylake server. Client platforms like Coffee
Lake do not have the required feature bits set in CPUID.
Changelog
---------
Link to previous version (v14):
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=55981&state=*
v15:
(1) Rebased on top of latest master.
(2) Addressed review comments from Dave Hansen.
(3) Moved code for getting or setting pkey bits to new
helpers. These changes replace patch 7 of v14.
(4) Added a fix which ensures that the correct count of
reserved keys is used across different platforms.
(5) Added a fix which ensures that the correct page size
is used as powerpc supports both 4K and 64K pages.
v14:
(1) Incorporated another round of comments from Dave Hansen.
v13:
(1) Incorporated comments for Dave Hansen.
(2) Added one more test for correct pkey-0 behavior.
v12:
(1) Fixed the offset of pkey field in the siginfo structure for
x86_64 and powerpc. And tries to use the actual field
if the headers have it defined.
v11:
(1) Fixed a deadlock in the ptrace testcase.
v10 and prior:
(1) Moved the testcase to arch neutral directory.
(2) Split the changes into incremental patches.

currently the property entry kunit tests are built if CONFIG_KUNIT=y.
This will cause warnings when merged with the kunit tree that now
supports tristate CONFIG_KUNIT. While the tests appear to compile
as a module, we get a warning about missing module license.
It's better to have a per-test suite CONFIG variable so that
we can do selective building of kunit-based suites, and can
also avoid merge issues like this.

[PATCH v2 0/8] vdso: Complete the conversion to 32bit syscalls
by Vincenzo Frascino
This patch series is a follow up to "lib/vdso, x86/vdso: Fix fallout
from generic VDSO conversion" [1].
The main purpose is to complete the 32bit vDSOs conversion to use the
legacy 32bit syscalls as a fallback. With the conversion of all the
architectures present in -next complete, this patch series removes as
well the conditional choice in between 32 and 64 bit for 32bit vDSOs.
This series has been rebased on linux-next/master.

[PATCH] [RFC] kunit: move binary assertion out of line
by Arnd Bergmann
In combination with the structleak gcc plugin, kunit can lead to excessive
stack usage when each assertion adds another structure to the stack from
of the calling function:
base/test/property-entry-test.c:99:1: error: the frame size of 3032 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
As most assertions are binary, change those over to a direct function
call that does not have this problem. This can probably be improved
further, I just went for a straightforward conversion, but a function
call with 12 fixed arguments plus varargs it not great either.

I think improving the compiler or the plugin to not force the
allocation of these structs would be better, as it avoids the
whack-a-mole game of fixing up each time it hits us, but this
may not be possible using the current plugin infrastructure.

[PATCH kunit] kunit: building kunit as a module breaks allmodconfig
by Alan Maguire
kunit tests that do not support module build should depend
on KUNIT=y rather than just KUNIT in Kconfig, otherwise
they will trigger compilation errors for "make allmodconfig"
builds.

[PATCH v2] selftests/lkdtm: Add tests for LKDTM targets
by Kees Cook
This adds a basic framework for running all the "safe" LKDTM tests. This
will allow easy introspection into any selftest logs to examine the
results of most LKDTM tests.
Signed-off-by: Kees Cook <keescook(a)chromium.org>
---
v2: refreshed for v5.5, added new tests since v1
v1: https://lore.kernel.org/lkml/201905091013.E228F0F0BE@keescook/

What is the best way to compare an unsigned and a constant?
by SeongJae Park
Hello,
I have a function returning 'unsigned long', and would like to write a kunit
test for the function, as below.
unsigned long foo(void)
{
return 42;
}
static void foo_test(struct kunit *test)
{
KUNIT_EXPECT_EQ(test, 42, foo());
}
However, this kunit gives me below warning for the above code:
/.../linux/include/linux/kernel.h:842:29: warning: comparison of distinct pointer types lacks a cast
(!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
^
/.../linux/include/kunit/test.h:493:9: note: in expansion of macro ‘__typecheck’
((void)__typecheck(__left, __right)); \
^~~~~~~~~~~
/.../linux/include/kunit/test.h:517:2: note: in expansion of macro ‘KUNIT_BASE_BINARY_ASSERTION’

/.../linux/include/kunit/test.h:606:2: note: in expansion of macro ‘KUNIT_BASE_EQ_MSG_ASSERTION’

/.../linux/include/kunit/test.h:979:2: note: in expansion of macro ‘KUNIT_BINARY_EQ_ASSERTION’
KUNIT_BINARY_EQ_ASSERTION(test, KUNIT_EXPECTATION, left, right)
^~~~~~~~~~~~~~~~~~~~~~~~~
/.../linux/mm/foo-test.h:565:2: note: in expansion of macro ‘KUNIT_EXPECT_EQ’
KUNIT_EXPECT_EQ(test, 42, foo());
^~~~~~~~~~~~~~~
I could remove the warning by explicitly type casting the constant as below:
KUNIT_EXPECT_EQ(test, (unsigned long)42, foo());
However, now 'checkpatch.pl' complains about the type casting as below.
WARNING: Unnecessary typecast of c90 int constant
#565: FILE: mm/foo-test.h:565:
+ KUNIT_EXPECT_EQ(test, (unsigned long)42, foo());
Of course, there could be several work-arounds for these warnings, such as
using 'EXPECT_TRUE(test, 42 == foo())' or casting the function's return value.
Nonetheless, I'm not sure what is the right way. Could you please let me know
what is the recommended way for this case?
Thanks,

[PATCH v3 0/8] Create a userfaultfd demand paging test
by Ben Gardon
When handling page faults for many vCPUs during demand paging, KVM's MMU
lock becomes highly contended. This series creates a test with a naive
userfaultfd based demand paging implementation to demonstrate that
contention. This test serves both as a functional test of userfaultfd
and a microbenchmark of demand paging performance with a variable number
of vCPUs and memory per vCPU.
The test creates N userfaultfd threads, N vCPUs, and a region of memory
with M pages per vCPU. The N userfaultfd polling threads are each set up
to serve faults on a region of memory corresponding to one of the vCPUs.
Each of the vCPUs is then started, and touches each page of its disjoint
memory region, sequentially. In response to faults, the userfaultfd
threads copy a static buffer into the guest's memory. This creates a
worst case for MMU lock contention as we have removed most of the
contention between the userfaultfd threads and there is no time required
to fetch the contents of guest memory.
This test was run successfully on Intel Haswell, Broadwell, and
Cascadelake hosts with a variety of vCPU counts and memory sizes.
This test was adapted from the dirty_log_test.
The series can also be viewed in Gerrit here:
https://linux-review.googlesource.com/c/virt/kvm/kvm/+/1464
(Thanks to Dmitry Vyukov <dvyukov(a)google.com> for setting up the Gerrit
instance)

[RESEND PATCH v7 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 v6:
- reintroduce kunit_test_suite() definition to handle users in other trees
not yet converted to using kunit_test_suites() (kbuild error when
applying patches to ext4/dev tree)
- modify drivers/base/power/qos-test.c to use kunit_test_suites()
to register suite. We do not convert it to support module build now as
the suite uses a few unexported function; see patch 3 for details.
Changes since v5:
- fixed fs/ext4/Makefile to remove unneeded conditional compilation
(Iurii, patch 3)
- added Reviewed-by, Acked-by to patches 3, 4, 5 and 6
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
