[PATCH 0/1] mm/gup_benchmark: fix MAP_HUGETLB case

by John Hubbard

Hi, Here's another gup_benchmark.c fix, which I ran into while adding support for the upcoming FOLL_PIN work. Anyway, the problem is clearly described in the patch commit description, and the fix seems like the best way to me, but the fix is not *completely* black and white. This fix forces MAP_ANONYMOUS for the MAP_HUGETLB case. However, another way to do it might be to mmap() against a valid hugetlb page file, instead of /dev/zero. But that seems like a lot of trouble and if I'm reading the intent correctly, MAP_ANONYMOUS is what's desired anyway.

[PATCH][v3] kselftest: Fix NULL INSTALL_PATH for TARGETS runlist

by Prabhakar Kushwaha

As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from runlist") failed targets were excluded from the runlist. But value $$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead $$INSTALL_PATH. So, fix Makefile to use $INSTALL_PATH.

[PATCH 2/2][SRU][DISCO][EOAN] UBUNTU: SAUCE: seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test

by Christian Brauner

[PATCH][v2] kselftest: Fix NULL INSTALL_PATH for TARGETS runlist

by Prabhakar Kushwaha

As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from runlist") failed targets were excluded from the runlist. But value $$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead $$INSTALL_PATH. So, fix Makefile to use $INSTALL_PATH.

[PATCH v3 1/2] clone3: add CLONE_CLEAR_SIGHAND

by Christian Brauner

Reset all signal handlers of the child not set to SIG_IGN to SIG_DFL. Mutually exclusive with CLONE_SIGHAND to not disturb other thread's signal handler. In the spirit of closer cooperation between glibc developers and kernel developers (cf. [2]) this patchset came out of a discussion on the glibc mailing list for improving posix_spawn() (cf. [1], [3], [4]). Kernel support for this feature has been explicitly requested by glibc and I see no reason not to help them with this. The child helper process on Linux posix_spawn must ensure that no signal handlers are enabled, so the signal disposition must be either SIG_DFL or SIG_IGN. However, it requires a sigprocmask to obtain the current signal mask and at least _NSIG sigaction calls to reset the signal handlers for each posix_spawn call or complex state tracking that might lead to data corruption in glibc. Adding this flags lets glibc avoid these problems. [1]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00149.html [3]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00158.html [4]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00160.html [2]: https://lwn.net/Articles/799331/ '[...] by asking for better cooperation with the C-library projects in general. They should be copied on patches containing ABI changes, for example. I noted that there are often times where C-library developers wish the kernel community had done things differently; how could those be avoided in the future? Members of the audience suggested that more glibc developers should perhaps join the linux-api list. The other suggestion was to "copy Florian on everything".'

[PATCH v6 1/9] hugetlb_cgroup: Add hugetlb_cgroup reservation counter

by Mina Almasry

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

[PATCH] seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test

by Christian Brauner

The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of the former ifndef's scope. 2019-10-20 11:14:01 make run_tests -C seccomp make: Entering directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf seccomp_bpf.c: In function ‘user_notification_continue’: seccomp_bpf.c:3562:15: error: ‘SECCOMP_USER_NOTIF_FLAG_CONTINUE’ undeclared (first use in this function) resp.flags = SECCOMP_USER_NOTIF_FLAG_CONTINUE; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ seccomp_bpf.c:3562:15: note: each undeclared identifier is reported only once for each function it appears in Makefile:12: recipe for target 'seccomp_bpf' failed make: *** [seccomp_bpf] Error 1 make: Leaving directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' Reported-by: kernel test robot <rong.a.chen(a)intel.com> Fixes: 0eebfed2954f ("seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE") Cc: linux-kselftest(a)vger.kernel.org Signed-off-by: Christian Brauner <christian.brauner(a)ubuntu.com> --- tools/testing/selftests/seccomp/seccomp_bpf.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/seccomp/seccomp_bpf.c b/tools/testing/selftests/seccomp/seccomp_bpf.c index 2519377ebda3..9669b81086cf 100644 --- a/tools/testing/selftests/seccomp/seccomp_bpf.c +++ b/tools/testing/selftests/seccomp/seccomp_bpf.c @@ -168,10 +168,6 @@ struct seccomp_metadata { #define SECCOMP_RET_USER_NOTIF 0x7fc00000U -#ifndef SECCOMP_USER_NOTIF_FLAG_CONTINUE -#define SECCOMP_USER_NOTIF_FLAG_CONTINUE 0x00000001 -#endif - #define SECCOMP_IOC_MAGIC '!' #define SECCOMP_IO(nr) _IO(SECCOMP_IOC_MAGIC, nr) #define SECCOMP_IOR(nr, type) _IOR(SECCOMP_IOC_MAGIC, nr, type) @@ -205,6 +201,10 @@ struct seccomp_notif_sizes { }; #endif +#ifndef SECCOMP_USER_NOTIF_FLAG_CONTINUE +#define SECCOMP_USER_NOTIF_FLAG_CONTINUE 0x00000001 +#endif + #ifndef seccomp int seccomp(unsigned int op, unsigned int flags, void *args) { -- 2.23.0

[BUGFIX PATCH 0/5] selftests: Fixes for 32bit arch

by Masami Hiramatsu

Hi, Here are some patches to fix some warnings/issues on 32bit arch (e.g. arm). When I built the ksefltest on arm, I hit some 32bit related warnings. Here are the patches to fix those issues. - [1/5] va_max was set 2^32 even on 32bit arch. This can make va_max == 0 and always fail. Make it 3GB on 32bit. - [2/5] Some VM tests requires 64bit user space, which should not run on 32bit arch. - [3/5] For counting the size of large file, we should use size_t instead of unsinged long. - [4/5] Gcc warns printf format for size_t and int64_t on 32bit arch. Use %llu and cast it. - [5/5] Gcc warns __u64 and pointer type castings. It should once translated to unsigned long. Thank you, --- Masami Hiramatsu (5): selftests: proc: Make va_max 3GB on 32bit arch selftests: vm: Build/Run 64bit tests only on 64bit arch selftests: net: Use size_t and ssize_t for counting file size selftests: net: Fix printf format warnings on arm selftests: sync: Fix cast warnings on arm tools/testing/selftests/net/so_txtime.c | 4 ++-- tools/testing/selftests/net/tcp_mmap.c | 8 ++++---- tools/testing/selftests/net/udpgso.c | 3 ++- tools/testing/selftests/net/udpgso_bench_tx.c | 3 ++- .../selftests/proc/proc-self-map-files-002.c | 11 ++++++++++- tools/testing/selftests/sync/sync.c | 6 +++--- tools/testing/selftests/vm/Makefile | 5 +++++ tools/testing/selftests/vm/run_vmtests | 10 ++++++++++ 8 files changed, 38 insertions(+), 12 deletions(-) -- Masami Hiramatsu (Linaro) <mhiramat(a)kernel.org>

[Bug report] "make run_tests -C bpf" hanging forever

by Liu Yiding

Hi All. The patch 5c069b6dedef "selftests: Move test output to diagnostic lines" from Apr 24, 2019, leads to `make run_tests -C bpf` hanging forever. Bpf includes many subtest, when cmd `make run_tests -C bpf` runs to test_lwt_seg6local.sh, task will hang and runner.sh never run next task. I checked ps aux, prefix.pl will never exit. ``` 91058 [ 811.451584] # [25] VAR __license type_id=24 linkage=1 91059 [ 811.451586]- 91060 [ 811.455365] # [26] DATASEC license size=0 vlen=1 size == 0 91061 [ 811.455367]- 91062 [ 811.457424] #- 91063 [ 811.457425]- 91064 [ 811.460912] # selftests: test_lwt_seg6local [PASS] 91065 [ 811.460914]- 91066 [ 3620.461986] Thu Oct 17 14:54:05 CST 2019 detected soft_timeout ``` Ignore test_lwt_seg6local and run `make run_tests -C bpf` again, task will hang on test_tc_tunnel.sh. Kushwaha also meet this issue, `make run_tests -C bpf` hang on test_lwt_ip_encap.sh (This test failed on my localhost). -- Best regards. Liu Yiding

Plan for hybrid testing

by Brendan Higgins

Hey Knut and Shuah, Following up on our offline discussion on Wednesday night: We decided that it would make sense for Knut to try to implement Hybrid Testing (testing that crosses the kernel userspace boundary) that he introduced here[1] on top of the existing KUnit infrastructure. We discussed several possible things in the kernel that Knut could test with the new Hybrid Testing feature as an initial example. Those were (in reverse order of expected difficulty): 1. RDS (Reliable Datagram Sockets) - We decided that, although this was one of the more complicated subsystems to work with, it was probably the best candidate for Knut to start with because it was in desperate need of better testing, much of the testing would require crossing the kernel userspace boundary to be effective, and Knut has access to RDS (since he works at Oracle). 2. KMOD - Probably much simpler than RDS, and the maintainer, Luis Chamberlain (CC'ed) would like to see better testing here, but probably still not as good as RDS because it is in less dire need of testing, collaboration on this would be more difficult, and Luis is currently on an extended vacation. Luis and I had already been discussing testing KMOD here[2]. 3. IP over USB - Least desirable option, but still possible. More complicated than KMOD, and not as easy to collaborate on as RDS. I don't really think we discussed how this would work. I remember that I mentioned that it would be easier if I sent out a patch that centralizes where KUnit tests are dispatched from in the kernel; I will try to get an RFC for that out, probably sometime next week. That should provide a pretty straightforward place for Knut to move his work on top of. The next question is what the userspace component of this should look like. To me it seems like we should probably have the kselftest test runner manage when the test gets run, and collecting and reporting the result of the test, but I think Knut has thought more about this than I, and Shuah is the kselftest maintainer, so I am guessing this will probably mostly be a discussion between the two of you. So I think we have a couple of TODOs between us: Brendan: - Need to send out patch that provides a single place where all tests are dispatched from. Knut: - Start splitting out the hybrid test stuff from the rest of the RFC you sent previously. Knut and Shuah: - Start figuring out what the userspace component of this will look like. Cheers!

Re: kunit.py should default to --build_dir=.kunit

That way, we make it super easy for people to run the unit tests.

I think the best way to make this work would be for kunit_tool to be able to detect all the tests with CONFIG_KUNIT as you suggest (or something like it). Luis actually already suggested it; however, we identified that this would likely not be as easy as it sounds as it is possible to have mutually exclusive CONFIGs. Luis pointed out that some researchers are currently working on a sat solver for Kconfig that we could use to potentially address this problem. Nevertheless, a complete solution in this regard is actually somewhat difficult. Shuah's solution was just to use CONFIG fragments in the meantime similar to what kselftest already does. I was leaning in that direction since kselftest already does that and we know that it works. Shuah, Luis, does this still match what you have been thinking?

Re: kunit.py should default to --build_dir=.kunit

+open list:KERNEL SELFTEST FRAMEWORK In case anyone in kselftest has any thoughts. On Thu, Oct 10, 2019 at 7:05 PM Theodore Ts'o <theodore.tso(a)gmail.com> wrote: > > I've been experimenting with the ext4 kunit test case, and something that would be really helpful is if the default is to store the object files for the ARCM=um kernel and its .config file in the top-level directory .kunit.

Because the kernel developer will want to be running unit tests as well as building kernels that can be run under whatever architecture they are normally developing for (for example, an x86 kernel that can be run using kvm; or a arm64 kernel that gets run on an Android device by using the "fastboot" command). So that means we don't want to be overwriting the object files and .config files for building the kernel for x86 when building the kunit kernel using the um arch. For example, for ext4, my ideal workflow might go something like this: That's a good point. > <hack hack hack> > % ./tools/testing/kunit/kunit.py run > <watch to see that unit tests succeed, and since most of the object files have already been built for the kunit kernel in be stored in the .kunit directory, this will be fast, since only the modified files will need to be recompiled> > % kbuild > <this is a script that builds an x86 kernel in /build/ext4-64 that is designed to be run under either kvm or in a GCE VM; since the kunit object files are stored in /build/ext4-kunit, the pre-existing files when building for x86_64 haven't been disturbed, so this build is fast as well> > % kvm-xfstests smoke > <this will run xfstests using the kernel plucked from /build/ext-64, using kvm> > > The point is when I'm developing an ext4 feature, or reviewing and merging ext4 commits, I need to be able to maintain separate build trees and separate config files for ARCH=um as well as ARCH=x86_64, and if the ARCH=um are stored in the kernel sources, then building with O=... doesn't work: > > <tytso@lambda> {/usr/projects/linux/kunit} (kunit) > 1084% make O=/build/test-dir > make[1]: Entering directory '/build/test-dir' > *** > *** The source tree is not clean, please run 'make mrproper' > *** in /usr/projects/linux/kunit > *** Should we maybe drop `--build_dir` in favor of `O`? > One of the other reasons why it would be good to use --build_dir by default is that way, building with a separate O= build directory is regularly tested. Right now, "kunit.py --build_dir=" seems to be broken. Good point. > % ./tools/testing/kunit/kunit.py run --build_dir=/build/ext4-kunit > Generating .config ... > [22:04:12] Building KUnit Kernel ... > /usr/projects/linux/kunit/arch/x86/um/user-offsets.c:20:10: fatal error: asm/syscalls_64.h: No such file or directory > 20 | #include <asm/syscalls_64.h> > | ^~~~~~~~~~~~~~~~~~~ > compilation terminated. > > (This appears to be an ARCH=um bug, not a kunit bug, though.) Yeah, I encountered this before. Some file is not getting properly cleaned up by `make mrproper`. It works if you do `git clean -fdx` (I know that's not a real solution for most people). Nevertheless, it sounds like we need to sit down and actually solve this problem since it is affecting users now. I think you make a compelling argument. Anyone else have any thoughts on this?

[PATCH AUTOSEL 5.3 23/89] selftests/kselftest/runner.sh: Add 45 second timeout per test

by Sasha Levin

From: Kees Cook <keescook(a)chromium.org> [ Upstream commit 852c8cbf34d3b3130a05c38064dd98614f97d3a8 ] Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") solves the problem of kselftest_harness.h-using binary tests possibly hanging forever. However, scripts and other binaries can still hang forever. This adds a global timeout to each test script run. To make this configurable (e.g. as needed in the "rtc" test case), include a new per-test-directory "settings" file (similar to "config") that can contain kselftest-specific settings. The first recognized field is "timeout". Additionally, this splits the reporting for timeouts into a specific "TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

[PATCH linux-kselftest/test v2] lib/list-test: add a test for the 'list' doubly linked list

by David Gow

Add a KUnit test for the kernel doubly linked list implementation in include/linux/list.h Each test case (list_test_x) is focused on testing the behaviour of the list function/macro 'x'. None of the tests pass invalid lists to these macros, and so should behave identically with DEBUG_LIST enabled and disabled. Note that, at present, it only tests the list_ types (not the singly-linked hlist_), and does not yet test all of the list_for_each_entry* macros (and some related things like list_prepare_entry). Signed-off-by: David Gow <davidgow(a)google.com> --- Addressed the various comments on v1. The biggest change is the renaming of all of the testcases from the form x_test to list_test_x. I'm not super happy with how that looks (not the least because it ends up with 'list' twice), but it is more consistent with the proc/sysctl tests.

[PATCH 1/2] pidfd: verify task is alive when printing fdinfo

by Christian Brauner

Currently, when a task is dead we still print the pid it used to use in the fdinfo files of its pidfds. This doesn't make much sense since the pid may have already been reused. So verify that the task is still alive. If the task is not alive anymore, we will print -1. This allows us to differentiate between a task not being present in a given pid namespace - in which case we already print 0 - and a task having been reaped. Note that this uses PIDTYPE_PID for the check. Technically, we could've checked PIDTYPE_TGID since pidfds currently only refer to thread-group leaders but if they won't anymore in the future then this check becomes problematic without it being immediately obvious to non-experts imho. If a thread is created via clone(CLONE_THREAD) than struct pid has a single non-empty list pid->tasks[PIDTYPE_PID] and this pid can't be used as a PIDTYPE_TGID meaning pid->tasks[PIDTYPE_TGID] will return NULL even though the thread-group leader might still be very much alive. We could be more complicated and do something like: bool alive = false; rcu_read_lock(); struct task_struct *tsk = pid_task(pid, PIDTYPE_PID); if (tsk && task_tgid(tsk)) alive = true; rcu_read_unlock(); but it's really not worth it. We already have created a pidfd and we thus know it refers to a thread-group leader. Checking PIDTYPE_PID is fine and is easier to maintain should we ever allow pidfds to refer to threads.

[PATCH v2] selftests: Add kselftest-all and kselftest-install targets

by Shuah Khan

Add kselftest-all target to build tests from the top level Makefile. This is to simplify kselftest use-cases for CI and distributions where build and test systems are different. Current kselftest target builds and runs tests on a development system which is a developer use-case. Add kselftest-install target to install tests from the top level Makefile. This is to simplify kselftest use-cases for CI and distributions where build and test systems are different. This change addresses requests from developers and testers to add support for installing kselftest from the main Makefile. In addition, make the install directory the same when install is run using "make kselftest-install" or by running kselftest_install.sh. Also fix the INSTALL_PATH variable conflict between main Makefile and selftests Makefile. Signed-off-by: Shuah Khan <skhan(a)linuxfoundation.org> --- Changes since v1: - Collpased two patches that added separate targets to build and install into one patch using pattern rule to invoke all, install, and clean targets from main Makefile.

[PATCH linux-kselftest/test v6] ext4: add kunit test for decoding extended timestamps

by Iurii Zaikin

KUnit tests for decoding extended 64 bit timestamps that verify the seconds part of [a/c/m] timestamps in ext4 inode structs are decoded correctly. Test data is derived from the table in the Inode Timestamps section of Documentation/filesystems/ext4/inodes.rst. KUnit tests run during boot and output the results to the debug log in TAP format (http://testanything.org/). Only useful for kernel devs running KUnit test harness and are not for inclusion into a production build.

[PATCH linux-kselftest/test v5] ext4: add kunit test for decoding extended timestamps

by Iurii Zaikin

KUnit tests for decoding extended 64 bit timestamps that verify the seconds part of [a/c/m] timestamps in ext4 inode structs are decoded correctly. KUnit tests, which run on boot and output the results to the debug log in TAP format (http://testanything.org/). are only useful for kernel devs running KUnit test harness. Not for inclusion into a production build. Test data is derived from the table under Documentation/filesystems/ext4/inodes.rst Inode Timestamps.

[PATCH v3 0/3] ftrace: Introduce PERMANENT ftrace_ops flag

by Miroslav Benes

Livepatch uses ftrace for redirection to new patched functions. It means that if ftrace is disabled, all live patched functions are disabled as well. Toggling global 'ftrace_enabled' sysctl thus affect it directly. It is not a problem per se, because only administrator can set sysctl values, but it still may be surprising. Introduce PERMANENT ftrace_ops flag to amend this. If the FTRACE_OPS_FL_PERMANENT is set on any ftrace ops, the tracing cannot be disabled by disabling ftrace_enabled. Equally, a callback with the flag set cannot be registered if ftrace_enabled is disabled. v2->v3: - ftrace_enabled explicitly set to true - selftest from Joe Lawrence (I just split it to two patches) - typo fix v1->v2: - different logic, proposed by Joe Lawrence Joe Lawrence (2): selftests/livepatch: Make dynamic debug setup and restore generic selftests/livepatch: Test interaction with ftrace_enabled Miroslav Benes (1): ftrace: Introduce PERMANENT ftrace_ops flag Documentation/trace/ftrace-uses.rst | 8 +++ Documentation/trace/ftrace.rst | 4 +- include/linux/ftrace.h | 3 + kernel/livepatch/patch.c | 3 +- kernel/trace/ftrace.c | 23 ++++++- tools/testing/selftests/livepatch/Makefile | 3 +- .../testing/selftests/livepatch/functions.sh | 34 +++++++--- .../selftests/livepatch/test-callbacks.sh | 2 +- .../selftests/livepatch/test-ftrace.sh | 65 +++++++++++++++++++ .../selftests/livepatch/test-livepatch.sh | 2 +- .../selftests/livepatch/test-shadow-vars.sh | 2 +- 11 files changed, 132 insertions(+), 17 deletions(-) create mode 100755 tools/testing/selftests/livepatch/test-ftrace.sh -- 2.23.0

[PATCH linux-kselftest/test v3] lib/list-test: add a test for the 'list' doubly linked list

by David Gow

Add a KUnit test for the kernel doubly linked list implementation in include/linux/list.h Each test case (list_test_x) is focused on testing the behaviour of the list function/macro 'x'. None of the tests pass invalid lists to these macros, and so should behave identically with DEBUG_LIST enabled and disabled. Note that, at present, it only tests the list_ types (not the singly-linked hlist_), and does not yet test all of the list_for_each_entry* macros (and some related things like list_prepare_entry). Signed-off-by: David Gow <davidgow(a)google.com> --- Note: v2 can be found here: https://lkml.org/lkml/2019/10/10/1011 This revision fixes some issues with the memory allocation in the 'list_test_list_init' test. In particular, it uses a KUnit assert to verify that the lists allocated with kmalloc() and kzalloc() are non-NULL (and also properly passes GFP_KERNEL to them). Since this depends on KUnit, which is not yet upstream, it probably makes sense for it to go into the linux-kselftest/test branch alongside KUnit itself. v2 has ended up in the -mm tree, and is already in -next, though. I think it nevertheless makes sense to move this change to the linux-kselftest/test branch, as outlined here: https://lore.kernel.org/linux-kselftest/CABVgOS=W4cfFoE=JT4mbk1zkUsreucrw_B… Thanks, -- David MAINTAINERS | 5 + lib/Kconfig.debug | 12 + lib/Makefile | 3 + lib/list-test.c | 740 ++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 760 insertions(+) create mode 100644 lib/list-test.c diff --git a/MAINTAINERS b/MAINTAINERS index 7ef985e01457..9ccabdb25a26 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -9504,6 +9504,11 @@ F: Documentation/misc-devices/lis3lv02d.rst F: drivers/misc/lis3lv02d/ F: drivers/platform/x86/hp_accel.c +LIST UNIT TEST +M: David Gow <davidgow(a)google.com> +S: Maintained +F: lib/list-test.c + LIVE PATCHING M: Josh Poimboeuf <jpoimboe(a)redhat.com> M: Jiri Kosina <jikos(a)kernel.org> diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index a3017a5dadcd..7b648141ff52 100644 --- a/lib/Kconfig.debug +++ b/lib/Kconfig.debug @@ -1961,6 +1961,18 @@ config SYSCTL_KUNIT_TEST If unsure, say N. +config LIST_TEST + bool "KUnit Test for Kernel Linked-list structures" + depends on KUNIT + help + This builds the linked list unit test, which runs on boot. + It tests that the API and basic functionality of the list_head type + and associated macros. + For more information on KUnit and unit tests in general please refer + to the KUnit documentation in Documentation/dev-tools/kunit/. + + If unsure, say N. + config TEST_UDELAY tristate "udelay test driver" help diff --git a/lib/Makefile b/lib/Makefile index bba1fd5485f7..309e174ee35d 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -292,3 +292,6 @@ obj-$(CONFIG_GENERIC_LIB_MULDI3) += muldi3.o obj-$(CONFIG_GENERIC_LIB_CMPDI2) += cmpdi2.o obj-$(CONFIG_GENERIC_LIB_UCMPDI2) += ucmpdi2.o obj-$(CONFIG_OBJAGG) += objagg.o + +# KUnit tests +obj-$(CONFIG_LIST_TEST) += list-test.o diff --git a/lib/list-test.c b/lib/list-test.c new file mode 100644 index 000000000000..de6de4ef32c9 --- /dev/null +++ b/lib/list-test.c @@ -0,0 +1,740 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * KUnit test for the Kernel Linked-list structures. + * + * Copyright (C) 2019, Google LLC. + * Author: David Gow <davidgow(a)google.com> + */ +#include <kunit/test.h> + +#include <linux/list.h> + +struct list_test_struct { + int data;

[PATCH] kernel-doc: rename the kernel-doc directive 'functions' to 'specific'

by Changbin Du

The 'functions' directive is not only for functions, but also works for structs/unions. So the name is misleading. This patch renames it to 'specific', so now we have export/internal/specific directives to limit the functions/types to be included in documentation. Meanwhile we improved the warning message.

[PATCH] pidfd: fix selftest compilation by removing linux/wait.h

by Christian Kellner

From: Christian Kellner <christian(a)kellner.me> The pidfd_{open,poll}_test.c files both include `linux/wait.h` and later `sys/wait.h`. The former has `#define P_ALL 0`, but in the latter P_ALL is part of idtype_t enum, where it gets substituted due to the aforementioned define to be `0`, which then results in `typedef enum {0, ...`, which then results into a compiler error: "error: expected identifier before numeric constant". Since we need `sys/wait.h` for waitpid, drop `linux/wait.h`.

[ANN] New git repository for Autogenerated regression tests

by Shuah Khan

I created a new kernel.org repository for compiling and preserving Autogenerated regression tests. This is an outcome based on decision made at the Maintainer Summit to preserve and use the autogenerated reproducers for regression testing. Linux Kernel Autogenerated Regression Tests =========================================== linux-arts repository is dedicated to preserving the autogenerated regression tests for regression testing. Automates testing entities such as Syzbot generate reproducers to test the kernel. It is a manual process to download reproducers and once the bug is fixed, kernel developers loose track of these reproducers. As per the decision made at a session at the Maintainers Summit 2019, this git repository is created to preserve the reproducers. Please find the details on the discussion that lead to this decision at https://lwn.net/Articles/799162/ Please find the new git repo at: https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-arts.git/ The initial commit pulls in Syzkaller reproducers from Dmitry Vyukov. As per Dmitry's request, the run and build scripts have been updated to with just the syzbot link. Thanks Dmitry for compiling these reproducers and working on the framework of running and building them. As for reproducers, each .c is specific to syzbot report and named with the syzbot bug report ID. Please play with it and let me know if you have questions. README has the details on where to send patches and regressions tests. thanks, -- Shuah

[PATCH v2] riscv: add support for SECCOMP and SECCOMP_FILTER

by David Abdurachmanov

This patch was extensively tested on Fedora/RISCV (applied by default on top of 5.2-rc7 kernel for <2 months). The patch was also tested with 5.3-rc on QEMU and SiFive Unleashed board. libseccomp (userspace) was rebased: https://github.com/seccomp/libseccomp/pull/134 Fully passes libseccomp regression testing (simulation and live).

kseltest: bpf: test_lwt_ip_encap.sh: Why -l used in test_gso

by Prabhakar Kushwaha

Hi All, I am trying to understand test_gso test for IPv4 and IPv6 with following piece of code # listen on IPv*_DST, capture TCP into $TMPFILE if [ "${PROTO}" == "IPv4" ] ; then IP_DST=${IPv4_DST} ip netns exec ${NS3} bash -c \ "nc -4 -l -s ${IPv4_DST} -p 9000 > ${TMPFILE} &" elif [ "${PROTO}" == "IPv6" ] ; then IP_DST=${IPv6_DST} ip netns exec ${NS3} bash -c \ "nc -6 -l -s ${IPv6_DST} -p 9000 > ${TMPFILE} &" RET=$? else echo " test_gso: unknown PROTO: ${PROTO}" fi I have couple of queries around it a) why -l is being used for reading listen on IPv*_DST with -s option. I was looking at https://www.computerhope.com/unix/nc.htm, following has been mentioned: -l : Used to specify that nc should listen for an incoming connection rather than initiate a connection to a remote host. It is an error to use this option in conjunction with the -p, -s, or -z options. Additionally, any timeouts specified with the -w option are ignored. b) Even if there is requirement of -l option to use. can we provide timeout option also. how? as -w dont work with -l. I am facing an issue with Linux-5.3 Kselftest where even if test_lwt_ip_encap.sh "exit", bpf/runner.sh is not running next test case. It just wait until CRTL + c is pressed. If I comment above code things work fine. Please sugggest --prabhakar (pk)

Bugzilla Component for KUnit?

by Brendan Higgins

Hi, I am thinking about requesting a Bugzilla component for my kernel project KUnit. I am not sure if this is the right place for it. Some background on KUnit: We are working on adding unit testing for the Linux kernel[1][2]. We have our initial patchset that introduces the subsystem in the process of being merged (Linus sent our PR back to us for a minor fix[3], so it should be in either 5.4-rc2 or 5.5, but is nevertheless in linux-next). However, we also have a staging repo that people are using and some supporting code that lives outside of the kernel. So I am trying to figure out: 1. Is it appropriate to request a Bugzilla component before our subsystem has been merged into torvalds/master? I would just wait, but I have some users looking to file issues, so I would prefer to provide them something sooner rather than later. 2. Is it appropriate to use the kernel's Bugzilla to track issues outside of the Linux kernel? As I mention above, we have code that lives outside of the kernel; is it appropriate to use kernel.org's Bugzilla for this? 3. Does Bugzilla match my planned usage model? It doesn't look like Bugzilla get's much usage aside from reporting bugs. I want to use it for tracking feature progress and things like that. Is that okay? If kernel.org's Bugzilla is not a fit for what I want to do, that's fine. I just want to make sure before I go off and potentially fracture a central bug repository by creating my own somewhere else. Thanks!

[PATCH v2 0/2] gup.c, gup_benchmark.c trivial fixes before the storm

by John Hubbard

Hi, Changes since v1: 1) Fixed a krobot-reported mistake, which also uncovered a pre-existing bug. Thanks to Kirill for recommending the fix. 2) Added another small fix: changed the data type to unsigned int, as pointed out by Ira. 2) Added a "Fixes:" line, thanks to Kirill and Aneesh for pinpointing the commit. 3) Collected Acked-by and Suggested-by's. Original cover letter, edited slightly ====================================== These trivial fixes apply to today's linux.git (5.4-rc3). I found these while polishing up the Next And Final get_user_pages()+dma tracking patchset (which is in final testing and passing nicely...so far). Anyway, as these two patches apply cleanly both before and after the larger gup/dma upcoming patchset, I thought it best to send this out separately, in order to avoid muddying the waters more than usual.

[PATCH v5 0/7] hugetlb_cgroup: Add hugetlb_cgroup reservation limits

by Mina Almasry

Patch series implements hugetlb_cgroup reservation usage and limits, which track hugetlb reservations rather than hugetlb memory faulted in. Details of the approach is 1/7. Changes in v5: - Moved the bulk of the description to the first patch in the series. - Clang formatted the entire series. - Split off 'hugetlb: remove duplicated code' and 'hugetlb: region_chg provides only cache entry' into their own patch series. - Added comments to HUGETLB_RES enum. - Fixed bug in 'hugetlb: disable region_add file_region coalescing' calculating the wrong number of regions_needed in some cases. - Changed sleeps in test to proper conditions. - Misc fixes in test based on shuah@ review. Changes in v4: - Split up 'hugetlb_cgroup: add accounting for shared mappings' into 4 patches for better isolation and context on the indvidual changes: - hugetlb_cgroup: add accounting for shared mappings - hugetlb: disable region_add file_region coalescing - hugetlb: remove duplicated code - hugetlb: region_chg provides only cache entry - Fixed resv->adds_in_progress accounting. - Retained behavior that region_add never fails, in earlier patchsets region_add could return failure. - Fixed libhugetlbfs failure. - Minor fix to the added tests that was preventing them from running on some environments. Changes in v3: - Addressed comments of Hillf Danton: - Added docs. - cgroup_files now uses enum. - Various readability improvements. - Addressed comments of Mike Kravetz. - region_* functions no longer coalesce file_region entries in the resv_map. - region_add() and region_chg() refactored to make them much easier to understand and remove duplicated code so this patch doesn't add too much complexity. - Refactored common functionality into helpers. Changes in v2: - Split the patch into a 5 patch series. - Fixed patch subject.

[PATCH 0/2] gup.c, gup_benchmark.c trivial fixes before the storm

by John Hubbard

Hi, These trivial fixes apply to today's linux.git (5.4-rc3, or maybe -rc4, by the time I send this). I found these while polishing up the Next And Final get_user_pages()+dma tracking patchset (which is in final testing and passing nicely...so far). Anyway, as these two patches apply cleanly both before and after the larger gup/dma upcoming patchset, I thought it best to send this out separately, in order to avoid muddying the waters more than usual.

[PATCH 1/2] clone3: add CLONE3_CLEAR_SIGHAND

by Christian Brauner

Reset all signal handlers of the child not set to SIG_IGN to SIG_DFL. Mutually exclusive with CLONE_SIGHAND to not disturb other thread's signal handler. In the spirit of closer cooperation between glibc developers and kernel developers (cf. [2]) this patchset came out of a discussion on the glibc mailing list for improving posix_spawn() (cf. [1], [3], [4]). Kernel support for this feature has been explicitly requested by glibc and I see no reason not to help them with this. The child helper process on Linux posix_spawn must ensure that no signal handlers are enabled, so the signal disposition must be either SIG_DFL or SIG_IGN. However, it requires a sigprocmask to obtain the current signal mask and at least _NSIG sigaction calls to reset the signal handlers for each posix_spawn call or complex state tracking that might lead to data corruption in glibc. Adding this flags lets glibc avoid these problems. [1]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00149.html [3]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00158.html [4]: https://www.sourceware.org/ml/libc-alpha/2019-10/msg00160.html [2]: https://lwn.net/Articles/799331/ '[...] by asking for better cooperation with the C-library projects in general. They should be copied on patches containing ABI changes, for example. I noted that there are often times where C-library developers wish the kernel community had done things differently; how could those be avoided in the future? Members of the audience suggested that more glibc developers should perhaps join the linux-api list. The other suggestion was to "copy Florian on everything".'
