From: SeongJae Park <sjpark(a)amazon.de> This patchset contains trivial fixes for the kunit documentations and the wrapper python scripts. This patchset is based on 'kselftest/test' branch of linux-kselftest[1] and depends on Heidi's patch[2]. A complete tree is available at my repo: https://github.com/sjp38/linux/tree/kunit_fix/20191205_v5 Changes from v4 (https://lore.kernel.org/linux-doc/1575490683-13015-1-git-send-email-sj38.pa…): - Rebased on Heidi Fahim's patch[2] - Fix failing kunit_tool_test test - Add 'build_dir' option test in 'kunit_tool_test.py' Changes from v3 (https://lore.kernel.org/linux-kselftest/20191204192141.GA247851@google.com): - Fix the 4th patch, "kunit: Place 'test.log' under the 'build_dir'" to set default value of 'build_dir' as '' instead of NULL so that kunit can run even though '--build_dir' option is not given. Changes from v2 (https://lore.kernel.org/linux-kselftest/1575361141-6806-1-git-send-email-sj…): - Make 'build_dir' if not exists (missed from v3 by mistake) Changes from v1 (https://lore.kernel.org/linux-doc/1575242724-4937-1-git-send-email-sj38.par…): - Remove "docs/kunit/start: Skip wrapper run command" (A similar approach is ongoing) - Make 'build_dir' if not exists SeongJae Park (6): docs/kunit/start: Use in-tree 'kunit_defconfig' kunit: Remove duplicated defconfig creation kunit: Create default config in '--build_dir' kunit: Place 'test.log' under the 'build_dir' kunit: Rename 'kunitconfig' to '.kunitconfig' kunit/kunit_tool_test: Test '--build_dir' option run Documentation/dev-tools/kunit/start.rst | 13 +++++-------- tools/testing/kunit/kunit.py | 18 +++++++++++------- tools/testing/kunit/kunit_kernel.py | 10 +++++----- tools/testing/kunit/kunit_tool_test.py | 10 +++++++++- 4 files changed, 30 insertions(+), 21 deletions(-) -- [1] git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git [2] "kunit: testing kunit: Bug fix in test_run_timeout function", https://lore.kernel.org/linux-kselftest/CAFd5g47a7a8q7by+1ALBtepeegLvfkgwvC…) 2.17.1

[PATCH 1/2] kselftest/runner: Print new line in print of timeout log

by SeongJae Park

From: SeongJae Park <sjpark(a)amazon.de> If a timeout failure occurs, kselftest kills the test process and prints the timeout log. If the test process has killed while printing a log that ends with new line, the timeout log can be printed in middle of the test process output so that it can be seems like a comment, as below: # test_process_log not ok 3 selftests: timers: nsleep-lat # TIMEOUT This commit avoids such problem by printing one more line before the TIMEOUT failure log.

[PATCH v8 00/26] mm/gup: track dma-pinned pages: FOLL_PIN

by John Hubbard

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

[PATCH AUTOSEL 5.4 327/350] libbpf: Fix call relocation offset calculation bug

by Sasha Levin

From: Andrii Nakryiko <andriin(a)fb.com> [ Upstream commit a0d7da26ce86a25e97ae191cb90574ada6daea98 ] When relocating subprogram call, libbpf doesn't take into account relo->text_off, which comes from symbol's value. This generally works fine for subprograms implemented as static functions, but breaks for global functions. Taking a simplified test_pkt_access.c as an example: __attribute__ ((noinline)) static int test_pkt_access_subprog1(volatile struct __sk_buff *skb) { return skb->len * 2; } __attribute__ ((noinline)) static int test_pkt_access_subprog2(int val, volatile struct __sk_buff *skb) { return skb->len + val; } SEC("classifier/test_pkt_access") int test_pkt_access(struct __sk_buff *skb) { if (test_pkt_access_subprog1(skb) != skb->len * 2) return TC_ACT_SHOT; if (test_pkt_access_subprog2(2, skb) != skb->len + 2) return TC_ACT_SHOT; return TC_ACT_UNSPEC; } When compiled, we get two relocations, pointing to '.text' symbol. .text has st_value set to 0 (it points to the beginning of .text section): 0000000000000008 000000050000000a R_BPF_64_32 0000000000000000 .text 0000000000000040 000000050000000a R_BPF_64_32 0000000000000000 .text test_pkt_access_subprog1 and test_pkt_access_subprog2 offsets (targets of two calls) are encoded within call instruction's imm32 part as -1 and 2, respectively: 0000000000000000 test_pkt_access_subprog1: 0: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0) 1: 64 00 00 00 01 00 00 00 w0 <<= 1 2: 95 00 00 00 00 00 00 00 exit 0000000000000018 test_pkt_access_subprog2: 3: 61 10 00 00 00 00 00 00 r0 = *(u32 *)(r1 + 0) 4: 04 00 00 00 02 00 00 00 w0 += 2 5: 95 00 00 00 00 00 00 00 exit 0000000000000000 test_pkt_access: 0: bf 16 00 00 00 00 00 00 r6 = r1 ===> 1: 85 10 00 00 ff ff ff ff call -1 2: bc 01 00 00 00 00 00 00 w1 = w0 3: b4 00 00 00 02 00 00 00 w0 = 2 4: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0) 5: 64 02 00 00 01 00 00 00 w2 <<= 1 6: 5e 21 08 00 00 00 00 00 if w1 != w2 goto +8 <LBB0_3> 7: bf 61 00 00 00 00 00 00 r1 = r6 ===> 8: 85 10 00 00 02 00 00 00 call 2 9: bc 01 00 00 00 00 00 00 w1 = w0 10: 61 62 00 00 00 00 00 00 r2 = *(u32 *)(r6 + 0) 11: 04 02 00 00 02 00 00 00 w2 += 2 12: b4 00 00 00 ff ff ff ff w0 = -1 13: 1e 21 01 00 00 00 00 00 if w1 == w2 goto +1 <LBB0_3> 14: b4 00 00 00 02 00 00 00 w0 = 2 0000000000000078 LBB0_3: 15: 95 00 00 00 00 00 00 00 exit Now, if we compile example with global functions, the setup changes.

All that is shifted by number of instructions in main program, given all sub-programs are copied over after main program. Convert few selftests relying on bpf-to-bpf calls to use global functions instead of static ones.

[PATCH AUTOSEL 5.4 307/350] selftests, bpf: Workaround an alu32 sub-register spilling issue

by Sasha Levin

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

[PATCH AUTOSEL 5.4 306/350] selftests, bpf: Fix test_tc_tunnel hanging

by Sasha Levin

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

[PATCH AUTOSEL 5.4 267/350] bpf, testing: Workaround a verifier failure for test_progs

by Sasha Levin

From: Yonghong Song <yhs(a)fb.com> [ Upstream commit b7a0d65d80a0c5034b366392624397a0915b7556 ] With latest llvm compiler, running test_progs will have the following verifier failure for test_sysctl_loop1.o: libbpf: load bpf program failed: Permission denied libbpf: -- BEGIN DUMP LOG --- libbpf: invalid indirect read from stack var_off (0x0; 0xff)+196 size 7 ... libbpf: -- END LOG -- libbpf: failed to load program 'cgroup/sysctl' libbpf: failed to load object 'test_sysctl_loop1.o' The related bytecode looks as below: 0000000000000308 LBB0_8: 97: r4 = r10 98: r4 += -288 99: r4 += r7 100: w8 &= 255 101: r1 = r10 102: r1 += -488 103: r1 += r8 104: r2 = 7 105: r3 = 0 106: call 106 107: w1 = w0 108: w1 += -1 109: if w1 > 6 goto -24 <LBB0_5> 110: w0 += w8 111: r7 += 8 112: w8 = w0 113: if r7 != 224 goto -17 <LBB0_8> And source code: for (i = 0; i < ARRAY_SIZE(tcp_mem); ++i) { ret = bpf_strtoul(value + off, MAX_ULONG_STR_LEN, 0, tcp_mem + i); if (ret <= 0 || ret > MAX_ULONG_STR_LEN) return 0; off += ret & MAX_ULONG_STR_LEN; } Current verifier is not able to conclude that register w0 before '+' at insn 110 has a range of 1 to 7 and thinks it is from 0 - 255. This leads to more conservative range for w8 at insn 112, and later verifier complaint. Let us workaround this issue until we found a compiler and/or verifier solution.

[PATCH linux-kselftest/test v2] apparmor: add AppArmor KUnit tests for policy unpack

by Brendan Higgins

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

[PATCH v2] selftests: fix build behaviour on targets' failures

by Cristian Marussi

Currently, when some of the KSFT subsystems fails to build, the toplevel KSFT Makefile just keeps carrying on with the build process. This behaviour is expected and desirable especially in the context of a CI system running KSelfTest, since it is not always easy to guarantee that the most recent and esoteric dependencies are respected across all KSFT TARGETS in a timely manner. Unfortunately, as of now, this holds true only if the very last of the built subsystems could have been successfully compiled: if the last of those subsystem instead failed to build, such failure is taken as the whole outcome of the Makefile target and the complete build/install process halts even though many other preceding subsytems were in fact already built successfully. Fix the KSFT Makefile behaviour related to all/install targets in order to fail as a whole only when the all/install targets have failed for all of the requested TARGETS, while succeeding when at least one of TARGETS has been successfully built. Signed-off-by: Cristian Marussi <cristian.marussi(a)arm.com> --- This patch is based on ksft/fixes branch from: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git on top of commit (~5.5-rc1): 99e51aa8f701 Documentation: kunit: add documentation for kunit_tool Building with either: make kselftest-install \ KSFT_INSTALL_PATH=/tmp/KSFT \ TARGETS="exec arm64 bpf" make -C tools/testing/selftests install \ KSFT_INSTALL_PATH=/tmp/KSFT \ TARGETS="exec arm64 bpf" (with 'bpf' not building clean on my setup in the above case) and veryfying that build/install completes if at least one of TARGETS can be successfully built, and any successfully built subsystem is installed.

[PATCH 0/3] Reanme the definitions of INTERRUPT_PENDING, NMI_PENDING and TSC_OFFSETING

by Xiaoyao Li

When reading the codes, I find the definitions of interrupt-window exiting and nmi-window exiting don't match the names in latest intel SDM. I have no idea whether it's the historical names, rename them to match the latest SDM to avoid confusion. CPU_BASED_USE_TSC_OFFSETING mis-spelling in Patch 3 is found by checkpatch.pl.

[PATCH] selftests: net: ip_defrag: increase netdev_max_backlog

by Thadeu Lima de Souza Cascardo

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

This patchset is being developed here: <https://github.com/cyphar/linux/tree/openat2/master> Patch changelog: v18: * Further fixups from Al Viro: - Don't WARN_ON in complete_walk() check since it can be trivially triggered by userspace. Also, improve the comment so the purpose of the check is more clear. - Avoid duplicate smp_rmb() when in handle_dots() by doing __read_seqcount_retry(). - Drop vestigial UPGRADE_NO* flag definitions in uapi. * Update non-zero __padding test to include all bytes of the padding. v17: <https://lore.kernel.org/lkml/20191117011713.13032-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20191120050631.12816-1-cyphar@cyphar.com/> v16: <https://lore.kernel.org/lkml/20191116002802.6663-1-cyphar@cyphar.com/> v15: <https://lore.kernel.org/lkml/20191105090553.6350-1-cyphar@cyphar.com/> v14: <https://lore.kernel.org/lkml/20191010054140.8483-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20191026185700.10708-1-cyphar@cyphar.com> v13: <https://lore.kernel.org/lkml/20190930183316.10190-1-cyphar@cyphar.com/> v12: <https://lore.kernel.org/lkml/20190904201933.10736-1-cyphar@cyphar.com/> v11: <https://lore.kernel.org/lkml/20190820033406.29796-1-cyphar@cyphar.com/> <https://lore.kernel.org/lkml/20190728010207.9781-1-cyphar@cyphar.com/> v10: <https://lore.kernel.org/lkml/20190719164225.27083-1-cyphar@cyphar.com/> v09: <https://lore.kernel.org/lkml/20190706145737.5299-1-cyphar@cyphar.com/> v08: <https://lore.kernel.org/lkml/20190520133305.11925-1-cyphar@cyphar.com/> v07: <https://lore.kernel.org/lkml/20190507164317.13562-1-cyphar@cyphar.com/> v06: <https://lore.kernel.org/lkml/20190506165439.9155-1-cyphar@cyphar.com/> v05: <https://lore.kernel.org/lkml/20190320143717.2523-1-cyphar@cyphar.com/> v04: <https://lore.kernel.org/lkml/20181112142654.341-1-cyphar@cyphar.com/> v03: <https://lore.kernel.org/lkml/20181009070230.12884-1-cyphar@cyphar.com/> v02: <https://lore.kernel.org/lkml/20181009065300.11053-1-cyphar@cyphar.com/> v01: <https://lore.kernel.org/lkml/20180929103453.12025-1-cyphar@cyphar.com/> For a very long time, extending openat(2) with new features has been incredibly frustrating. This stems from the fact that openat(2) is possibly the most famous counter-example to the mantra "don't silently accept garbage from userspace" -- it doesn't check whether unknown flags are present[1]. This means that (generally) the addition of new flags to openat(2) has been fraught with backwards-compatibility issues (O_TMPFILE has to be defined as __O_TMPFILE|O_DIRECTORY|[O_RDWR or O_WRONLY] to ensure old kernels gave errors, since it's insecure to silently ignore the flag[2]). All new security-related flags therefore have a tough road to being added to openat(2). Furthermore, the need for some sort of control over VFS's path resolution (to avoid malicious paths resulting in inadvertent breakouts) has been a very long-standing desire of many userspace applications. This patchset is a revival of Al Viro's old AT_NO_JUMPS[3] patchset (which was a variant of David Drysdale's O_BENEATH patchset[4] which was a spin-off of the Capsicum project[5]) with a few additions and changes made based on the previous discussion within [6] as well as others I felt were useful. In line with the conclusions of the original discussion of AT_NO_JUMPS, the flag has been split up into separate flags. However, instead of being an openat(2) flag it is provided through a new syscall openat2(2) which provides several other improvements to the openat(2) interface (see the patch description for more details). The following new LOOKUP_* flags are added: * LOOKUP_NO_XDEV blocks all mountpoint crossings (upwards, downwards, or through absolute links). Absolute pathnames alone in openat(2) do not trigger this. Magic-link traversal which implies a vfsmount jump is also blocked (though magic-link jumps on the same vfsmount are permitted). * LOOKUP_NO_MAGICLINKS blocks resolution through /proc/$pid/fd-style links. This is done by blocking the usage of nd_jump_link() during resolution in a filesystem. The term "magic-links" is used to match with the only reference to these links in Documentation/, but I'm happy to change the name. It should be noted that this is different to the scope of ~LOOKUP_FOLLOW in that it applies to all path components. However, you can do openat2(NO_FOLLOW|NO_MAGICLINKS) on a magic-link and it will *not* fail (assuming that no parent component was a magic-link), and you will have an fd for the magic-link. In order to correctly detect magic-links, the introduction of a new LOOKUP_MAGICLINK_JUMPED state flag was required. * LOOKUP_BENEATH disallows escapes to outside the starting dirfd's tree, using techniques such as ".." or absolute links. Absolute paths in openat(2) are also disallowed. Conceptually this flag is to ensure you "stay below" a certain point in the filesystem tree -- but this requires some additional to protect against various races that would allow escape using "..". Currently LOOKUP_BENEATH implies LOOKUP_NO_MAGICLINKS, because it can trivially beam you around the filesystem (breaking the protection). In future, there might be similar safety checks done as in LOOKUP_IN_ROOT, but that requires more discussion. In addition, two new flags are added that expand on the above ideas: * LOOKUP_NO_SYMLINKS does what it says on the tin. No symlink resolution is allowed at all, including magic-links. Just as with LOOKUP_NO_MAGICLINKS this can still be used with NOFOLLOW to open an fd for the symlink as long as no parent path had a symlink component. * LOOKUP_IN_ROOT is an extension of LOOKUP_BENEATH that, rather than blocking attempts to move past the root, forces all such movements to be scoped to the starting point. This provides chroot(2)-like protection but without the cost of a chroot(2) for each filesystem operation, as well as being safe against race attacks that chroot(2) is not. If a race is detected (as with LOOKUP_BENEATH) then an error is generated, and similar to LOOKUP_BENEATH it is not permitted to cross magic-links with LOOKUP_IN_ROOT. The primary need for this is from container runtimes, which currently need to do symlink scoping in userspace[7] when opening paths in a potentially malicious container. There is a long list of CVEs that could have bene mitigated by having RESOLVE_THIS_ROOT (such as CVE-2017-1002101, CVE-2017-1002102, CVE-2018-15664, and CVE-2019-5736, just to name a few). In order to make all of the above more usable, I'm working on libpathrs[8] which is a C-friendly library for safe path resolution. It features a userspace-emulated backend if the kernel doesn't support openat2(2). Hopefully we can get userspace to switch to using it, and thus get openat2(2) support for free once it's ready. Future work would include implementing things like RESOLVE_NO_AUTOMOUNT and possibly a RESOLVE_NO_REMOTE (to allow programs to be sure they don't hit DoSes though stale NFS handles).

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

[PATCH v5 linux-kselftest-test 0/6] kunit: support building core/tests as modules

by Alan Maguire

The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 3. Changes since v4: - fixed signoff chain to use Co-developed-by: prior to Knut's signoff (Stephen, all patches) - added Reviewed-by, Tested-by for patches 1, 2, 4 and 6 - updated comment describing try-catch-impl.h (Stephen, patch 2) - fixed MODULE_LICENSEs to be GPL v2 (Stephen, patches 3, 5) - added __init to kunit_init() (Stephen, patch 5) Changes since v3: - removed symbol lookup patch for separate submission later - removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed with Brendan and Stephen) - disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this is to avoid having to deal with symbol lookup issues - changed string-stream-impl.h back to string-stream.h (Brendan) - added module build support to new list, ext4 tests Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported symbols (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) Alan Maguire (6): kunit: move string-stream.h to lib/kunit kunit: hide unexported try-catch interface in try-catch-impl.h kunit: allow kunit tests to be loaded as a module kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 ++ Documentation/dev-tools/kunit/usage.rst | 16 ++++++++++ fs/ext4/Kconfig | 2 +- fs/ext4/Makefile | 5 +++ fs/ext4/inode-test.c | 4 ++- include/kunit/assert.h | 3 +- include/kunit/test.h | 35 ++++++++++++++------ include/kunit/try-catch.h | 10 ------ kernel/sysctl-test.c | 4 ++- lib/Kconfig.debug | 4 +-- lib/kunit/Kconfig | 6 ++-- lib/kunit/Makefile | 14 +++++--- lib/kunit/assert.c | 10 ++++++ lib/kunit/{example-test.c => kunit-example-test.c} | 4 ++- lib/kunit/{test-test.c => kunit-test.c} | 7 ++-- lib/kunit/string-stream-test.c | 5 +-- lib/kunit/string-stream.c | 3 +- {include => lib}/kunit/string-stream.h | 0 lib/kunit/test.c | 25 ++++++++++++++- lib/kunit/try-catch-impl.h | 27 ++++++++++++++++ lib/kunit/try-catch.c | 37 +++++----------------- lib/list-test.c | 4 ++- 23 files changed, 160 insertions(+), 71 deletions(-) rename lib/kunit/{example-test.c => kunit-example-test.c} (97%) rename lib/kunit/{test-test.c => kunit-test.c} (98%) rename {include => lib}/kunit/string-stream.h (100%) create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1

selftests: l2tp tests

by Colin Ian King

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

[PATCH v7 00/25] Unify vDSOs across more architectures

by Vincenzo Frascino

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

[BUGFIX PATCH] selftests/x86: Check the availablity of sys/syscall.h

by Masami Hiramatsu

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

[PATCH kselftest-next 1/2] kselftests: memcg: update the oom group leaf events test

by Roman Gushchin

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

[PATCH v4 0/4] PM / QoS: Restore DEV_PM_QOS_MIN/MAX_FREQUENCY

by Leonard Crestez

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

[PATCH] fs/ext4/inode-test: Fix inode test on 32 bit platforms.

by Iurii Zaikin

Fixes the issue caused by the fact that in C in the expression of the form -1234L only 1234L is the actual literal, the unary minus is an operation applied to the literal. Which means that to express the lower bound for the type one has to negate the upper bound and subtract 1.

[GIT PULL] seccomp updates for v5.5-rc1

by Kees Cook

Hi Linus, Please pull these seccomp updates for v5.5-rc1. Mostly this is implementing the new flag SECCOMP_USER_NOTIF_FLAG_CONTINUE, but there are cleanups as well. Most notably, the secure_computing() prototype has changed (to remove an unused argument), but this has happened at the same time as riscv adding seccomp support, so the cleanest merge order would be to merge riscv first, then seccomp with the following patch for riscv to handle the change from "seccomp: simplify secure_computing()": diff --git a/arch/riscv/kernel/ptrace.c b/arch/riscv/kernel/ptrace.c index 0f84628b9385..407464201b91 100644 --- a/arch/riscv/kernel/ptrace.c +++ b/arch/riscv/kernel/ptrace.c @@ -159,7 +159,7 @@ __visible void do_syscall_trace_enter(struct pt_regs *regs) * If this fails we might have return value in a0 from seccomp * (via SECCOMP_RET_ERRNO/TRACE). */ - if (secure_computing(NULL) == -1) { + if (secure_computing() == -1) { syscall_set_nr(current, regs, -1); return; } Thanks! -Kees The following changes since commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce: Linux 5.4-rc2 (2019-10-06 14:27:30 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git tags/seccomp-v5.5-rc1 for you to fetch changes up to 23b2c96fad21886c53f5e1a4ffedd45ddd2e85ba: seccomp: rework define for SECCOMP_USER_NOTIF_FLAG_CONTINUE (2019-10-28 12:29:46 -0700) ---------------------------------------------------------------- seccomp updates for v5.5 - implement SECCOMP_USER_NOTIF_FLAG_CONTINUE (Christian Brauner) - fixes to selftests (Christian Brauner) - remove secure_computing() argument (Christian Brauner) ---------------------------------------------------------------- Christian Brauner (6): seccomp: avoid overflow in implicit constant conversion seccomp: add SECCOMP_USER_NOTIF_FLAG_CONTINUE seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE seccomp: simplify secure_computing() seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test seccomp: rework define for SECCOMP_USER_NOTIF_FLAG_CONTINUE arch/arm/kernel/ptrace.c | 2 +- arch/arm64/kernel/ptrace.c | 2 +- arch/parisc/kernel/ptrace.c | 2 +- arch/s390/kernel/ptrace.c | 2 +- arch/um/kernel/skas/syscall.c | 2 +- arch/x86/entry/vsyscall/vsyscall_64.c | 2 +- include/linux/seccomp.h | 6 +- include/uapi/linux/seccomp.h | 29 +++++++ kernel/seccomp.c | 28 +++++-- tools/testing/selftests/seccomp/seccomp_bpf.c | 110 +++++++++++++++++++++++++- 10 files changed, 169 insertions(+), 16 deletions(-) -- Kees Cook

[PATCH v7 00/24] mm/gup: track dma-pinned pages: FOLL_PIN

by John Hubbard

Hi, OK, here is v7, maybe this is the last one. The corresponding git repo and branch is: git@github.com:johnhubbard/linux.git pin_user_pages_tracking_v7 Ira, you reviewed the gup_benchmark patches a bit earlier, but I removed one or two of those review-by tags, due to invasive changes I made after your review (in response to further reviews). So could you please reply to any patches you'd like to have reviewed-by's restoredto, if any? Mainly I'm thinking of "mm/gup_benchmark: support pin_user_pages() and related calls". Also various FOLL_LONGTERM vs pin_longterm*() patches. The following blurb from the v6 cover letter is still applicable, and I'll repeat it here so it doesn't get lost in the patch blizzard: Christoph Hellwig has a preference to do things a little differently, for the devmap cleanup in patch 5 ("mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages"). That came up in a different review thread, because the patch is out for review in two locations. Here's that review thread: https://lore.kernel.org/r/20191118070826.GB3099@infradead.org ...and I'm hoping that we can defer that request, because otherwise it derails this series, which is starting to otherwise look like it could be ready for 5.5. Changes since v6: * Renamed a couple of routines, to get rid of unnecessary leading underscores: __pin_compound_head() --> grab_compound_head() __record_subpages() --> record_subpages() * Fixed the error fallback (put_compound_head()) so as to match the fix in the previous version: need to put back N * GUP_PIN_COUNTING_BIAS pages, for FOLL_PIN cases. * Factored out yet another common chunk of code, into a new grab_page() routine. * Added a missing compound_head() call to put_compound_head(). * [Re-]added Jens Axboe's reviewed-by tag to the fs/io_uring patch. * Added more reviewed-by's from Jan Kara. Changes since v5: * Fixed the refcounting for huge pages: in most cases, it was only taking one GUP_PIN_COUNTING_BIAS's worth of refs, when it should have been taking one GUP_PIN_COUNTING_BIAS for each subpage. (Much thanks to Jan Kara for spotting that one!) * Renamed user_page_ref_inc() to try_pin_page(), and added a new try_pin_compound_head(). This definitely improves readability. * Factored out some more duplication in the FOLL_PIN and FOLL_GET cases, in gup.c. * Fixed up some straggling "get_" --> "pin_" references in the comments. * Added reviewed-by tags. Changes since v4: * Renamed put_user_page*() --> unpin_user_page(). * Removed all pin_longterm_pages*() calls. We will use FOLL_LONGTERM at the call sites. (FOLL_PIN, however, remains an internal gup flag). This is very nice: many patches just change three characters now: get_user_pages --> pin_user_pages. I think we've found the right balance of wrapper calls and gup flags, for the call sites. * Updated a lot of documentation and commit logs to match the above two large changes. * Changed gup_benchmark tests and run_vmtests, to adapt to one less use case: there is no pin_longterm_pages() call anymore. * This includes a new devmap cleanup patch from Dan Williams, along with a rebased follow-up: patches 4 and 5, already mentioned above. * Fixed patch 10 ("mm/gup: introduce pin_user_pages*() and FOLL_PIN"), so as to make pin_user_pages*() calls act as placeholders for the corresponding get_user_pages*() calls, until a later patch fully implements the DMA-pinning functionality. Thanks to Jan Kara for noticing that. * Fixed the implementation of pin_user_pages_remote(). * Further tweaked patch 2 ("mm/gup: factor out duplicate code from four routines"), in response to Jan Kara's feedback. * Dropped a few reviewed-by tags due to changes that invalidated them. Changes since v3: * VFIO fix (patch 8): applied further cleanup: removed a pre-existing, unnecessary release and reacquire of mmap_sem. Moved the DAX vma checks from the vfio call site, to gup internals, and added comments (and commit log) to clarify. * Due to the above, made a corresponding fix to the pin_longterm_pages_remote(), which was actually calling the wrong gup internal function. * Changed put_user_page() comments, to refer to pin*() APIs, rather than get_user_pages*() APIs. * Reverted an accidental whitespace-only change in the IB ODP code. * Added a few more reviewed-by tags. Changes since v2: * Added a patch to convert IB/umem from normal gup, to gup_fast(). This is also posted separately, in order to hopefully get some runtime testing. * Changed the page devmap code to be a little clearer, thanks to Jerome for that. * Split out the page devmap changes into a separate patch (and moved Ira's Signed-off-by to that patch). * Fixed my bug in IB: ODP code does not require pin_user_pages() semantics. Therefore, revert the put_user_page() calls to put_page(), and leave the get_user_pages() call as-is. * As part of the revert, I am proposing here a change directly from put_user_pages(), to release_pages(). I'd feel better if someone agrees that this is the best way. It uses the more efficient release_pages(), instead of put_page() in a loop, and keep the change to just a few character on one line, but OTOH it is not a pure revert. * Loosened the FOLL_LONGTERM restrictions in the __get_user_pages_locked() implementation, and used that in order to fix up a VFIO bug. Thanks to Jason for that idea. * Note the use of release_pages() in IB: is that OK? * Added a few more WARN's and clarifying comments nearby. * Many documentation improvements in various comments. * Moved the new pin_user_pages.rst from Documentation/vm/ to Documentation/core-api/ . * Commit descriptions: added clarifying notes to the three patches (drm/via, fs/io_uring, net/xdp) that already had put_user_page() calls in place. * Collected all pending Reviewed-by and Acked-by tags, from v1 and v2 email threads. * Lot of churn from v2 --> v3, so it's possible that new bugs sneaked in. NOT DONE: separate patchset is required: * __get_user_pages_locked(): stop compensating for buggy callers who failed to set FOLL_GET. Instead, assert that FOLL_GET is set (and fail if it's not). ====================================================================== Original cover letter (edited to fix up the patch description numbers) This applies cleanly to linux-next and mmotm, and also to linux.git if linux-next's commit 20cac10710c9 ("mm/gup_benchmark: fix MAP_HUGETLB case") is first applied there. This provides tracking of dma-pinned pages. This is a prerequisite to solving the larger problem of proper interactions between file-backed pages, and [R]DMA activities, as discussed in [1], [2], [3], and in a remarkable number of email threads since about 2017. :) A new internal gup flag, FOLL_PIN is introduced, and thoroughly documented in the last patch's Documentation/vm/pin_user_pages.rst. I believe that this will provide a good starting point for doing the layout lease work that Ira Weiny has been working on. That's because these new wrapper functions provide a clean, constrained, systematically named set of functionality that, again, is required in order to even know if a page is "dma-pinned". In contrast to earlier approaches, the page tracking can be incrementally applied to the kernel call sites that, until now, have been simply calling get_user_pages() ("gup"). In other words, opt-in by changing from this: get_user_pages() (sets FOLL_GET) put_page() to this: pin_user_pages() (sets FOLL_PIN) put_user_page() Because there are interdependencies with FOLL_LONGTERM, a similar conversion as for FOLL_PIN, was applied. The change was from this: get_user_pages(FOLL_LONGTERM) (also sets FOLL_GET) put_page() to this: pin_longterm_pages() (sets FOLL_PIN | FOLL_LONGTERM) put_user_page() ============================================================ Patch summary: * Patches 1-9: refactoring and preparatory cleanup, independent fixes * Patch 10: introduce pin_user_pages(), FOLL_PIN, but no functional changes yet * Patches 11-16: Convert existing put_user_page() callers, to use the new pin*() * Patch 17: Activate tracking of FOLL_PIN pages. * Patches 18-20: convert various callers * Patches: 21-23: gup_benchmark and run_vmtests support * Patch 24: rename put_user_page*() --> unpin_user_page*() ============================================================ Testing: * I've done some overall kernel testing (LTP, and a few other goodies), and some directed testing to exercise some of the changes. And as you can see, gup_benchmark is enhanced to exercise this. Basically, I've been able to runtime test the core get_user_pages() and pin_user_pages() and related routines, but not so much on several of the call sites--but those are generally just a couple of lines changed, each. Not much of the kernel is actually using this, which on one hand reduces risk quite a lot. But on the other hand, testing coverage is low. So I'd love it if, in particular, the Infiniband and PowerPC folks could do a smoke test of this series for me. Also, my runtime testing for the call sites so far is very weak: * io_uring: Some directed tests from liburing exercise this, and they pass. * process_vm_access.c: A small directed test passes. * gup_benchmark: the enhanced version hits the new gup.c code, and passes. * infiniband (still only have crude "IB pingpong" working, on a good day: it's not exercising my conversions at runtime...) * VFIO: compiles (I'm vowing to set up a run time test soon, but it's not ready just yet) * powerpc: it compiles... * drm/via: compiles... * goldfish: compiles... * net/xdp: compiles... * media/v4l2: compiles... ============================================================ Next: * Get the block/bio_vec sites converted to use pin_user_pages(). * Work with Ira and Dave Chinner to weave this together with the layout lease stuff. ============================================================ [1] Some slow progress on get_user_pages() (Apr 2, 2019): https://lwn.net/Articles/784574/ [2] DMA and get_user_pages() (LPC: Dec 12, 2018): https://lwn.net/Articles/774411/ [3] The trouble with get_user_pages() (Apr 30, 2018): https://lwn.net/Articles/753027/ Dan Williams (1): mm: Cleanup __put_devmap_managed_page() vs ->page_free() John Hubbard (23): mm/gup: pass flags arg to __gup_device_* functions mm/gup: factor out duplicate code from four routines mm/gup: move try_get_compound_head() to top, fix minor issues mm: devmap: refactor 1-based refcounting for ZONE_DEVICE pages goldish_pipe: rename local pin_user_pages() routine IB/umem: use get_user_pages_fast() to pin DMA pages media/v4l2-core: set pages dirty upon releasing DMA buffers vfio, mm: fix get_user_pages_remote() and FOLL_LONGTERM mm/gup: introduce pin_user_pages*() and FOLL_PIN goldish_pipe: convert to pin_user_pages() and put_user_page() IB/{core,hw,umem}: set FOLL_PIN via pin_user_pages*(), fix up ODP mm/process_vm_access: set FOLL_PIN via pin_user_pages_remote() drm/via: set FOLL_PIN via pin_user_pages_fast() fs/io_uring: set FOLL_PIN via pin_user_pages() net/xdp: set FOLL_PIN via pin_user_pages() mm/gup: track FOLL_PIN pages media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion vfio, mm: pin_user_pages (FOLL_PIN) and put_user_page() conversion powerpc: book3s64: convert to pin_user_pages() and put_user_page() mm/gup_benchmark: use proper FOLL_WRITE flags instead of hard-coding "1" mm/gup_benchmark: support pin_user_pages() and related calls selftests/vm: run_vmtests: invoke gup_benchmark with basic FOLL_PIN coverage mm, tree-wide: rename put_user_page*() to unpin_user_page*() Documentation/core-api/index.rst | 1 + Documentation/core-api/pin_user_pages.rst | 233 +++++++++ arch/powerpc/mm/book3s64/iommu_api.c | 12 +- drivers/gpu/drm/via/via_dmablit.c | 6 +- drivers/infiniband/core/umem.c | 19 +- drivers/infiniband/core/umem_odp.c | 13 +- drivers/infiniband/hw/hfi1/user_pages.c | 4 +- drivers/infiniband/hw/mthca/mthca_memfree.c | 8 +- drivers/infiniband/hw/qib/qib_user_pages.c | 4 +- drivers/infiniband/hw/qib/qib_user_sdma.c | 8 +- drivers/infiniband/hw/usnic/usnic_uiom.c | 4 +- drivers/infiniband/sw/siw/siw_mem.c | 4 +- drivers/media/v4l2-core/videobuf-dma-sg.c | 8 +- drivers/nvdimm/pmem.c | 6 - drivers/platform/goldfish/goldfish_pipe.c | 35 +- drivers/vfio/vfio_iommu_type1.c | 35 +- fs/io_uring.c | 6 +- include/linux/mm.h | 195 ++++++- include/linux/mmzone.h | 2 + include/linux/page_ref.h | 10 + mm/gup.c | 553 +++++++++++++++----- mm/gup_benchmark.c | 74 ++- mm/huge_memory.c | 44 +- mm/hugetlb.c | 36 +- mm/memremap.c | 76 ++- mm/process_vm_access.c | 28 +- mm/vmstat.c | 2 + net/xdp/xdp_umem.c | 4 +- tools/testing/selftests/vm/gup_benchmark.c | 21 +- tools/testing/selftests/vm/run_vmtests | 22 + 30 files changed, 1121 insertions(+), 352 deletions(-) create mode 100644 Documentation/core-api/pin_user_pages.rst -- 2.24.0

[PATCH] tools/testing/selftests/seccomp: change USER_NOTIF_MAGIC definition

by Max Filippov

USER_NOTIF_MAGIC is used to both initialize seccomp_notif_resp::val and verify syscall resturn value. On 32-bit architectures syscall return value has type long, but the value of USER_NOTIF_MAGIC has type long long because it doesn't fit into long. As a result all syscall return value comparisons with USER_NOTIF_MAGIC are false. This is also reported by the compiler when '-W' is added to CFLAGS. Add explicit type cast to USER_NOTIF_MAGIC definition. This fixes the following seccomp_bpf tests on 32-bit architectures: global.user_notification_basic global.user_notification_child_pid_ns global.user_notification_sibling_pid_ns global.user_notification_fault_recv Signed-off-by: Max Filippov <jcmvbkbc(a)gmail.com> --- tools/testing/selftests/seccomp/seccomp_bpf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/seccomp/seccomp_bpf.c b/tools/testing/selftests/seccomp/seccomp_bpf.c index 7f8b5c8982e3..16cc30e2ade4 100644 --- a/tools/testing/selftests/seccomp/seccomp_bpf.c +++ b/tools/testing/selftests/seccomp/seccomp_bpf.c @@ -3077,7 +3077,7 @@ static int user_trap_syscall(int nr, unsigned int flags) return seccomp(SECCOMP_SET_MODE_FILTER, flags, &prog); } -#define USER_NOTIF_MAGIC 116983961184613L +#define USER_NOTIF_MAGIC ((unsigned long)116983961184613L) TEST(user_notification_basic) { pid_t pid; -- 2.20.1
