[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".'

[PATCH v2 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".'

[PATCH v2 0/3] seccomp: continue syscall from notifier

by Christian Brauner

Hey everyone, /* v2 */ This is the patchset coming out of the KSummit session Kees and I gave in Lisbon last week (cf. [3] which also contains slides with more details on related things such as deep argument inspection). The simple idea is to extend the seccomp notifier to allow for the continuation of a syscall. The rationale for this can be found in the commit message to [1]. For the curious there is more detail in [2]. This patchset would unblock supervising an extended set of syscalls such as mount() where a privileged process is supervising the syscalls of a lesser privileged process and emulates the syscall for the latter in userspace. For more comments on security see [1] and the comments in include/uapi/linux/seccomp.h added by this patchset. Kees, if you prefer a pr the series can be pulled from: git@gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux tags/seccomp-notify-syscall-continue-v5.5 For anyone who wants to play with this it's sitting in: https://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux.git/log/?h=se… /* v1 */ Link: https://lore.kernel.org/r/20190919095903.19370-1-christian.brauner@ubuntu.c… - Kees Cook <keescook(a)chromium.org>: - dropped patch because it is already present in linux-next [PATCH 2/4] seccomp: add two missing ptrace ifdefines Link: https://lore.kernel.org/r/20190918084833.9369-3-christian.brauner@ubuntu.com /* v0 */ Link: https://lore.kernel.org/r/20190918084833.9369-1-christian.brauner@ubuntu.com Thanks!

[RFC PATCH] LTP Wrapper for Syzkaller reproducers

by Richard Palethorpe

First attempt at wrapping the Syzkaller reproducers in the LTP library. I am posting this in case anyone wants to experiment with it early or has a radically different approach in mind. This just uses exec to run the reproducer executables as per Metan's suggestion. There is a simple script which creates a runtest file allowing it to work with existing LTP test runners, albeit with a bit of extra work for now. This would benefit from the following LTP library patch: https://patchwork.ozlabs.org/patch/935568/ Running it without KASAN and the other kernel debugging options is not a good idea. We can easily detect when the kernel config is wrong and print a warning or even refuse to run, but I haven't added it yet. Having to download, compile and install the reproducers seperately is annoying and I bet most users won't do it. We can probably automate that as part of the install, it is just a question of how much we do as default. --- runtest/.gitignore | 1 + testcases/kernel/Makefile | 1 + testcases/kernel/syzkaller-repros/.gitignore | 1 + testcases/kernel/syzkaller-repros/Makefile | 10 +++ testcases/kernel/syzkaller-repros/README.md | 39 +++++++++ .../kernel/syzkaller-repros/gen-runtest.sh | 8 ++ testcases/kernel/syzkaller-repros/syzwrap.c | 85 +++++++++++++++++++ 7 files changed, 145 insertions(+) create mode 100644 runtest/.gitignore create mode 100644 testcases/kernel/syzkaller-repros/.gitignore create mode 100644 testcases/kernel/syzkaller-repros/Makefile create mode 100644 testcases/kernel/syzkaller-repros/README.md create mode 100755 testcases/kernel/syzkaller-repros/gen-runtest.sh create mode 100644 testcases/kernel/syzkaller-repros/syzwrap.c diff --git a/runtest/.gitignore b/runtest/.gitignore new file mode 100644 index 000000000..e3725dd42 --- /dev/null +++ b/runtest/.gitignore @@ -0,0 +1 @@ +syzkaller-repros diff --git a/testcases/kernel/Makefile b/testcases/kernel/Makefile index 3319b3163..0150cfb4f 100644 --- a/testcases/kernel/Makefile +++ b/testcases/kernel/Makefile @@ -53,6 +53,7 @@ SUBDIRS += connectors \ sched \ security \ sound \ + syzkaller-repros \ tracing \ uevents \ diff --git a/testcases/kernel/syzkaller-repros/.gitignore b/testcases/kernel/syzkaller-repros/.gitignore new file mode 100644 index 000000000..dbda1c71f --- /dev/null +++ b/testcases/kernel/syzkaller-repros/.gitignore @@ -0,0 +1 @@ +syzwrap diff --git a/testcases/kernel/syzkaller-repros/Makefile b/testcases/kernel/syzkaller-repros/Makefile new file mode 100644 index 000000000..8e74805c2 --- /dev/null +++ b/testcases/kernel/syzkaller-repros/Makefile @@ -0,0 +1,10 @@ +# SPDX-License-Identifier: GPL-2.0-or-later +# Copyright (c) 2019 Linux Test Project + +top_srcdir ?= ../../.. + +include $(top_srcdir)/include/mk/testcases.mk + +CFLAGS += -D_GNU_SOURCE + +include $(top_srcdir)/include/mk/generic_leaf_target.mk diff --git a/testcases/kernel/syzkaller-repros/README.md b/testcases/kernel/syzkaller-repros/README.md new file mode 100644 index 000000000..e95ae19e2 --- /dev/null +++ b/testcases/kernel/syzkaller-repros/README.md @@ -0,0 +1,39 @@ +LTP wrapper for Syzkaller reproducers +===================================== + +This allows you to run the autogenerated bug reproducers from the Syzkaller +fuzzer within the LTP framework.

[PATCH v8 00/12] Add arm64/signal initial kselftest support

by Cristian Marussi

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

[PATCH v7 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

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

[BUGFIX PATCH] selftests: Use real temporary working directory for archiving

by Masami Hiramatsu

Use real temporary working directory for generating kselftest archive. tools/testing/selftests/kselftest directory has been used for the temporary working directory for making a tar archive from gen_kselftest_tar.sh, and it removes the directory for cleanup. However, since the kselftest directory became a part of the repository, it must not be used as a working dir. Introduce mktemp to prepare a temporary working directory for archiving kselftests.

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

by David Gow

This change adds a KUnit test for the kernel doubly linked list implementation in include/linux/list.h Note that, at present, it only tests the list_ types (not the singly-linked hlist_), and does not yet test all of the list_for_each_entry* macros (and some related things like list_prepare_entry). This change depends on KUnit, so should be merged via the 'test' branch: https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/l… Signed-off-by: David Gow <davidgow(a)google.com> --- lib/Kconfig.debug | 12 + lib/Makefile | 3 + lib/list-test.c | 711 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 726 insertions(+) create mode 100644 lib/list-test.c diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index a3017a5dadcd..60691c0aac3e 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 stuctures" + 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..f333e8b0d9fe --- /dev/null +++ b/lib/list-test.c @@ -0,0 +1,711 @@ +// SPDX-License-Identifier: GPL-2.0 +#include <kunit/test.h> + +#include <linux/list.h> + +struct list_test_struct { + int data;

[GIT PULL] Kselftest update for Linux 5.4-rc3

by Shuah Khan

Hi Linus, Please pull the following Kselftest update for Linux 5.4-rc3. This Kselftest update for Linux 5.4-rc3 consists fixes for existing tests and the framework. Cristian Marussi's patches add ability to skip targets (tests) and exclude tests that didn't build from run-list. These patches improve the Kselftest results. Ability to skip targets helps avoid running tests that aren't supported in certain environments. As an example, bpf tests from mainline aren't supported on stable kernels and have dependency on bleeding edge llvm. Being able to skip bpf on systems that can't meet this llvm dependency will be helpful. Kselftest can be built and installed from the main Makefile. This change help simplify Kselftest use-cases which addresses request from users. Kees Cook added per test timeout support to limit individual test run-time. diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit 54ecb8f7028c5eb3d740bb82b0f1d90f2df63c5c: Linux 5.4-rc1 (2019-09-30 10:35:40 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux-kselftest-5.4-rc3 for you to fetch changes up to ce3a677802121e038d2f062e90f96f84e7351da0: selftests: watchdog: Add command line option to show watchdog_info (2019-10-02 13:44:43 -0600) ---------------------------------------------------------------- linux-kselftest-5.4-rc3 This Kselftest update for Linux 5.4-rc3 consists fixes for existing tests and the framework.

[PATCH linux-kselftest-test 0/3] kunit: support module-based build

by Alan Maguire

For consumers wishing to run kunit on real hardware, it would be ideal if the kunit framework and tests supported module-based builds. This is an advantage as it reduces the test task to running "modprobe mytests.ko", and CONFIG_KUNIT* options can be "always on" (or rather "always m"). KUnit based tests will load the kunit module as an implicit dependency.

[PATCH v6 00/11] Add arm64/signal initial kselftest support

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. This series is based on arm64/for-next/core [1]: commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel") A common internal test-case layout is proposed for signal tests and it is wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. This series converts also to this subdirectory scheme the pre-existing (already queued on arm64/for-next/core) KSFT arm64 tags tests, moving them into arm64/tags. Thanks Cristian [1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas for more TODO testcases: - fake_sigreturn_unmapped_sp: SP into unmapped addrs - fake_sigreturn_kernelspace_sp: SP into kernel addrs - fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed - fake_sigreturn_misaligned_sp_4: misaligned SP by 4 (i.e., __alignof__(struct _aarch64_ctx)) - fake_sigreturn_misaligned_sp_8: misaligned SP by 8 (i.e., sizeof(struct _aarch64_ctx)) - fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow __reserved[], but is not a multiple of 16 - fake_sigreturn_bad_size_tiny: a size that is less than 16 - fake_sigreturn_bad_size_overflow_tiny: a size that does overflow __reserved[], but by less than 16 bytes? - mangle_sve_invalid_extra_context: SVE extra_context invalid - SVE signal testcases and special handling will be part of an additional patch still to be released - KSFT arm64 tags test patch https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300… is relocated into its own directory under tools/testing/selftests/arm64/tags Changes: -------- v5-->v6: -

[PATCH] Documentation: kunit: Fix verification command

by SeongJae Park

kunit wrapper script ('kunit.py') receives a sub-command (only 'run' for now) as its argument. If no sub-command is given, it prints help message and just quit.

[PATCH v18 00/19] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Linus[1] and Randy[2], by moving top level `kunit/` directory to `lib/kunit/` and likewise moves top level Kconfig entry under lib/Kconfig.debug, so the KUnit submenu now shows up under the "Kernel Hacking" menu. As a consequence of this, I rewrote patch 06/18 (kbuild: enable building KUnit) - now 06/19 (lib: enable building KUnit in lib/), and now needs to be re-acked/reviewed. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[3]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[4]. Additionally for convenience, I have applied these patches to a branch[5]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/initial/v5.3/v18 branch. ## History since v15 ### v18 - Addrssed comments on 07/19 (kunit: test: add initial tests) from Randy Dunlap by removing redundant dependencies from Kconfig entries. ### v17 - Addressed comments on 06/19 (lib: enable building KUnit in lib/) from Stephen Boyd by moving KUnit submenu ahead of Runtime Testing submenu. ### v16 - Addressed comments from Linus Torvalds by moving all kunit/ paths to lib/kunit/. - Addressed comments by Randy Dunlap by moving KUnit Kconfig under lib/Kconfig.debug so the KUnit submenu shows up under the "Kernel Hacking" menu.

[RFC PATCH] selftests: fix build targets behaviour on failures

by Cristian Marussi

Currently, when some of the KSFT subsystems specified in TARGETS fails to build, the toplevel 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 where is not always easy to guarantee that the most recent and esoteric toolchain's 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 subsystems listed in TARGETS happened to be one that could be successfully built: if the last listed TARGETS fails, it is taken as the whole outcome of the Makefile target and the complete build/install halts even though many other preceding subsytems were in fact already successfully built. 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.

Linux 5.4 kselftest known issues

by Shuah Khan

Here are the know kselftest issues on Linux 5.4 with top commit commit 619e17cf75dd58905aa67ccd494a6ba5f19d6cc6 on x86_64: The goal is to get these addressed before 5.4 comes out. 3 build failures and status: pidfd - undefined reference to `pthread_create' collect2: error: ld returned 1 exit status Fixed: https://patchwork.kernel.org/patch/11159517/ bfp (two issues) 1. "make TARGETS=bpf kselftest" build fails Makefile:127: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. 2. Related to llvm latest version dependency. This is a hard dependency. Unless users upgrade to latest llvvm, bpf test won't run. The new llvm might not be supported on all distros yet, in which case bpf will not get tested in some rings and on some architectures. gpio "make TARGETS=gpio kselftest" build fails Makefile:23: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. kvm "make TARGETS=kvm kselftest" build fails due --no-pie flags. I am working on a fix for this. no-pie-option defines aren't working correctly and I suspect try-run miht not be defined in this kselftest build case. thanks, -- Shuah

[PATCH v3] selftests: kvm: Fix libkvm build error

by Shuah Khan

Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary, which is the case when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, both build variations work.

[PATCH RESEND] tools: gpio: Use !building_out_of_srctree to determine srctree

by Shuah Khan

make TARGETS=gpio kselftest fails with: Makefile:23: tools/build/Makefile.include: No such file or directory When the gpio tool make is invoked from tools Makefile, srctree is cleared and the current logic check for srctree equals to empty string to determine srctree location from CURDIR. When the build in invoked from selftests/gpio Makefile, the srctree is set to "." and the same logic used for srctree equals to empty is needed to determine srctree. Check building_out_of_srctree undefined as the condition for both cases to fix "make TARGETS=gpio kselftest" build failure.

[PATCH 0/9] Create a userfaultfd demand paging test

by Ben Gardon

When handling page faults for many vCPUs during demand paging, KVM's MMU lock becomes highly contended. This series creates a test with a naive userfaultfd based demand paging implementation to demonstrate that contention. This test serves both as a functional test of userfaultfd and a microbenchmark of demand paging performance with a variable number of vCPUs and memory per vCPU. The test creates N userfaultfd threads, N vCPUs, and a region of memory with M pages per vCPU. The N userfaultfd polling threads are each set up to serve faults on a region of memory corresponding to one of the vCPUs. Each of the vCPUs is then started, and touches each page of its disjoint memory region, sequentially. In response to faults, the userfaultfd threads copy a static buffer into the guest's memory. This creates a worst case for MMU lock contention as we have removed most of the contention between the userfaultfd threads and there is no time required to fetch the contents of guest memory. This test was run successfully on Intel Haswell, Broadwell, and Cascadelake hosts with a variety of vCPU counts and memory sizes. This test was adapted from the dirty_log_test. The series can also be viewed in Gerrit here: https://linux-review.googlesource.com/c/virt/kvm/kvm/+/1464 (Thanks to Dmitry Vyukov <dvyukov(a)google.com> for setting up the Gerrit instance) Ben Gardon (9): KVM: selftests: Create a demand paging test KVM: selftests: Add demand paging content to the demand paging test KVM: selftests: Add memory size parameter to the demand paging test KVM: selftests: Pass args to vCPU instead of using globals KVM: selftests: Support multiple vCPUs in demand paging test KVM: selftests: Time guest demand paging KVM: selftests: Add parameter to _vm_create for memslot 0 base paddr KVM: selftests: Support large VMs in demand paging test Add static flag tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 4 +- .../selftests/kvm/demand_paging_test.c | 610 ++++++++++++++++++ tools/testing/selftests/kvm/dirty_log_test.c | 2 +- .../testing/selftests/kvm/include/kvm_util.h | 3 +- tools/testing/selftests/kvm/lib/kvm_util.c | 7 +- 6 files changed, 621 insertions(+), 6 deletions(-) create mode 100644 tools/testing/selftests/kvm/demand_paging_test.c -- 2.23.0.444.g18eeb5a265-goog

[PATCH v2] selftests: kvm: Fix libkvm build error

by Shuah Khan

Fix the following build error from "make TARGETS=kvm kselftest": libkvm.a(assert.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC This error is seen when build is done from the main Makefile using kselftest target. In this case KBUILD_CPPFLAGS and CC_OPTION_CFLAGS are defined. When build is invoked using: "make -C tools/testing/selftests/kvm" KBUILD_CPPFLAGS and CC_OPTION_CFLAGS aren't defined. There is no need to pass in KBUILD_CPPFLAGS and CC_OPTION_CFLAGS for the check to determine if --no-pie is necessary1s, which is the when these two aren't defined when "make -C tools/testing/selftests/kvm" runs. Fix it by simplifying the no-pie-option logic. With this change, bith build variations work.

[PATCH AUTOSEL 5.3 50/71] selftests/bpf: adjust strobemeta loop to satisfy latest clang

by Sasha Levin

From: Andrii Nakryiko <andriin(a)fb.com> [ Upstream commit 4670d68b9254710fdeaf794cad54d8b2c9929e0a ] Some recent changes in latest Clang started causing the following warning when unrolling strobemeta test case main loop: progs/strobemeta.h:416:2: warning: loop not unrolled: the optimizer was unable to perform the requested transformation; the transformation might be disabled or specified as part of an unsupported transformation ordering [-Wpass-failed=transform-warning] This patch simplifies loop's exit condition to depend only on constant max iteration number (STROBE_MAX_MAP_ENTRIES), while moving early termination logic inside the loop body. The changes are equivalent from program logic standpoint, but fixes the warning. It also appears to improve generated BPF code, as it fixes previously failing non-unrolled strobemeta test cases.

[PATCH v13 0/9] namei: openat2(2) path resolution restrictions

by Aleksa Sarai

This patchset is being developed here: <https://github.com/cyphar/linux/tree/resolveat/master> It depends on the copy_struct_from_user() helpers being developed here: <https://github.com/cyphar/linux/tree/copy_struct_from_user/master> and posted here: <https://lore.kernel.org/lkml/20190930182810.6090-1-cyphar@cyphar.com/> Patch changelog: v13: * Fix race with the magic-link mode semantics by recomputing the mode during ->get_link() and storing it with nd_jump_link(). A selftest was added for this attack scenario as well. [Jann Horn] * Fix gap in RESOLVE_NO_XDEV with magic-links -- now magic-link resolution is only permitted if the link doesn't jump vfsmounts. * Remove path_is_under() checks for ".." resolution (due to the possibility of O(m*n) lookup behaviour). Instead, return -EAGAIN if a racing rename or mount occurs. Userspace is then encouraged to retry or have another fallback (if after several tries, it still fails it's likely that there is an attack going on -- though failures will occur spuriously because &{rename,mount}_lock are both global). [Linus Torvalds] * Move copy_struct_from_user() to a separate series so it can be merged separately. [Christian Brauner] * Small test improvements (mainly making the TAP output more readable and adding a few new minor test cases). Now the openat2(2) self-tests have ~271 overall test cases. * Expand on changes to path-lookup in the kernel docs. * Kernel-doc fixes.

This patchset is a revival of Al Viro's old AT_NO_JUMPS[1,2] patchset (which was a variant of David Drysdale's O_BENEATH patchset[3] which was a spin-off of the Capsicum project[4]) with a few additions and changes made based on the previous discussion within [5] 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. * 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[6] 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). And further, several semantics of file descriptor "re-opening" are now changed to prevent attacks like CVE-2019-5736 by restricting how magic-links can be resolved (based on their mode). This required some other changes to the semantics of the modes of O_PATH file descriptor's associated /proc/self/fd magic-links. openat2(2) has the ability to further restrict re-opening of its own O_PATH fds, so that users can make even better use of this feature. Finally, O_EMPTYPATH was added so that users can do /proc/self/fd-style re-opening without depending on procfs. The new restricted semantics for magic-links are applied here too. In order to make all of the above more usable, I'm working on libpathrs[7] 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.

[PATCH] tools: bpf: Use !building_out_of_srctree to determine srctree

by Shuah Khan

make TARGETS=bpf kselftest fails with: Makefile:127: tools/build/Makefile.include: No such file or directory When the bpf tool make is invoked from tools Makefile, srctree is cleared and the current logic check for srctree equals to empty string to determine srctree location from CURDIR.

[PATCH v3 0/2] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

by Ilya Leoshkevich

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

[PATCH v2] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)

by Ilya Leoshkevich

The current logic prepends $(OUTPUT) only to the first member of $(TEST_PROGS). Use $(addprefix) to prepend it to each member. Also, $(OUTPUT) is assumed to end with a / almost everywhere else in the kernel, make this the case for kselftest as well.

[PATCH v2 0/2] Fix KSFT toplevel makefile behaviour

by Cristian Marussi

Hi so this series carries two small fixes to the toplevel KSelfTest makefile which I found useful especially while attempting to run the suite in automation. [1/2] While it is already possible to specify a limited list of TARGETS to run, it is not instead easily possible to state a list of targets NOT to run (say due to specific instability issues). Moreover providing such a skip list through a stripped down list of TARGETS it is cumbersome and fragile since this poses the risk to stick to an old stale stripped TARGETS list once upstream decides to add more default targets. A new SKIP_TARGETS Makefile variable is provided by this patch to easily specify a skiplist for target subsystems. [2/2] Currently when some target fails to build, KSFT Makefile just carries on building as much subsystems as it can: unfortunately this is not properly reflected also in the generation of the runlist inside run_kselftest.sh. This patch rectifies this behaviour checking for the existence of a target directory in the INSTALL_PATH before adding the related snippet to the run_kselftest.sh script. Thanks Cristian Changelog v1 --> v2 - added Documentation - various typos fixed - added a proper override when filtering-out SKIP_TARGETS from TARGETS to make it work also when TARGETS is provided too from the cmdline Cristian Marussi (2): kselftest: add capability to skip chosen TARGETS kselftest: exclude failed TARGETS from runlist Documentation/dev-tools/kselftest.rst | 11 +++++++++++ tools/testing/selftests/Makefile | 11 +++++++++++ 2 files changed, 22 insertions(+) -- 2.17.1

bug in KBUILD_OUTPUT handling - for relative paths in kselftest

by Tim.Bird＠sony.com

I found a bug in kselftest KBUILD_OUTPUT handling. The following works: $ cd /home/tbird/work/linux $ export KBUILD_OUTPUT=/home/tbird/work/kbuild $ yes '' | make localmodconfig $ make TARGETS=size kselftest But this doesn't work: $ cd /home/tbird/work/linux $ export KBUILD_OUTPUT=../kbuild $ yes '' | make localmodconfig $ make TARGETS=size kselftest I see the following: make[1]: Entering directory '/home/tbird/work/kbuild' make --no-builtin-rules INSTALL_HDR_PATH=$BUILD/usr \ ARCH=x86 -C ../../.. headers_install INSTALL ../kbuild/kselftest/usr/include gcc -static -ffreestanding -nostartfiles -s get_size.c -o ../kbuild/kselftest/size/get_size /usr/bin/ld: cannot open output file ../kbuild/kselftest/size/get_size: No such file or directory collect2: error: ld returned 1 exit status ../lib.mk:138: recipe for target '../kbuild/kselftest/size/get_size' failed make[3]: *** [../kbuild/kselftest/size/get_size] Error 1 Makefile:136: recipe for target 'all' failed make[2]: *** [all] Error 2 /home/tbird/work/linux/Makefile:1240: recipe for target 'kselftest' failed make[1]: *** [kselftest] Error 2 make[1]: Leaving directory '/home/tbird/work/kbuild' Makefile:179: recipe for target 'sub-make' failed make: *** [sub-make] Error 2 This is due to the relative path for KBUILD_OUTPUT being handled incorrectly (I believe) in tools/testing/selftests/Makefile. There are these lines in the Makefile, which are responsible for creating the output directory: BUILD_TARGET=$$BUILD/$$TARGET mkdir $$BUILD_TARGET -p But these are executed from working directory tools/testing/selftests, so the 'size' directory gets created at tools/testing/kbuild/kselftest/size, instead of /home/tbird/work/kbuild/kselftest/size. I can add some code to the Makefile to change the assignment of the variable BUILD, so that if it is a relative path it is relative to $(top_srcdir) instead of the current directory. But I wanted to check and make sure that I'm not breaking anyone else's workflow. I'm not sure what the expectation would be for someone who did this: $ export KBUILD_OUTPUT=../kbuild ; make -C tools/testing/selftests run_tests But I assume if someone is running the kernel's 'make' from the top-level kernel source directory, and they have a relative KBUILD_OUTPUT directory, then they want that output directory to be relative to the top-level directory and not somewhere else. Should I just code up something for review? I use relative KBUILD_OUTPUT paths for a number of my kernel build scripts, and right now these are incompatible with kselftests. Thanks, -- Tim

Let the user specify an optional TARGETS skiplist through the new optional SKIP_TARGETS Makefile variable.

kunit: what do we do with the 'kunit/alpha/master' branch?

by David Gow

TL;DR: We expect KUnit to be accepted upstream into Linus' branch in the next week or two, and we now need to figure out what we are going to do with our non-upstream 'kunit/alpha/master' branch. Hello everyone, We've put together a rough proposal of what we should do with our not-upstream branch, known to most people using it as 'kunit/alpha/master'[1], now that KUnit's acceptance into mainline appears to be imminent (the KUnit MVP patchset is now in linux-next, and the merge window just opened). ========== Background ========== KUnit development is currently split between two versions: the 'kunit/alpha/master'[1] git branch, and the version being submitted to the upstream Linux kernel. While there are some good reasons to continue to have two separate versions of KUnit, at present there is some uncertainty around the difference between these versions, and in which circumstances each version is useful. At present, the 'kunit/alpha/master' branch serves a few different purposes. It is a place for code not-yet-ready for upstream -- such as the mocking framework -- while being developed, while also acting as a stable version for customers who do not wish to follow along with the changes made during the upstreaming process. Adding to the confusion, the name 'kunit/alpha/master' refers to an early (alpha) version of KUnit, and the version of KUnit being upstreamed has now diverged significantly from this version, requiring significant differences in documentation, and requiring a number of changes to tests when porting from one version to the other. Finally, it is not clear how the 'kunit/alpha/master' version should evolve as features it contains are upstreamed. On the other hand, the version being upstreamed has its own complications. It contains significantly fewer features (as features such as the mocking frameworks will be upstreamed individually), and so is less useful for the average customer. Until each feature is upstreamed, it is iterated on rapidly to address comments from the kernel community, so in-progress features are not stable enough to reasonably build on. Finally, it exists only as a set of patches on mailing lists, rather than as a maintained git repository (due to the fact that the patches themselves are changing rapidly), making it difficult for early adopters to incorporate into their own trees. Whilst we believe there to be enough (at times conflicting) goals above to justify having multiple versions of KUnit, we want to ensure that they are meeting their goals, and that we have a process to ensure that code finds its way into the correct version, that we can deprecate and remove failed experiments or superseded versions, and that we can keep pace with upstream kernel releases. ============ The Proposal ============ We propose having two tracks of development: the upstream kernel (comprising both code that has been upstreamed, and code which is in the process of being upstreamed -- i.e. is being reviewed on the mailing lists), and an 'experimental' branch, which contains features which are yet to be submitted upstream. Periodically, the 'experimental' branch will be replaced with a new 'experimental' branch based on the latest upstream version. This will allow us to focus on code based on upstream versions by deprecating earlier, experimental versions of features. The older experimental branch will stay around, but receive no new features or support: customers will need to eventually migrate to either the upstream kernel (if all of the features they require have been upstreamed), or to the latest 'experimental' branch (if they still require non-upstreamed features). Where practical, 'experimental' branches will try to provide a stable interface (and/or compatibility layers/shims) such that users can write tests against an experimental version and expect our changes to break them infrequently. We don't intend to make any solid guarantee, however: so users will need to be able to deal with some breakage. We expect most changes to KUnit to be submitted directly upstream, and reserve the 'experimental' branch for features where: a) the design is yet to be proven by early adopters, and is likely to change; b) the feature is large enough that having a solid staging environment in which several developers can work is necessary; and/or c) it depends on existing features only available in the 'experimental' branch. An example of features suited to the 'experimental' branch are the mocking systems[2]. ===================== Lifetime of a feature ===================== A new feature (that for one of the above reasons may require some experimentation before being sent upstream) would typically be developed as follows: 1. An initial version of the feature is developed against the latest 'experimental' branch. 2. The feature is tested by users of the 'experimental' branch. 3. It is revised as needed within the 'experimental' branch. If breaking changes are required, and supporting some form of compatibility layer is practical, such a layer is implemented to avoid breaking existing 'experimental' customers. 4. Once the feature is deemed ready, it is submitted to the mailing lists for the upstream kernel. Any compatibility layers for earlier experimental version are removed -- this is a 'clean' version of the change. 5. Development of the change continues on the kernel mailing lists: any particularly important changes or bugfixes are ported to the 'experimental' branch if feasible, but complete convergence is not expected at this stage. 6. When the feature is accepted upstream, a new 'experimental' branch is created based on the new upstream kernel. Development on the old 'experimental' branch ceases. 7. The upstream version of the feature has now superseded the experimental version. All future development is done based on the upstream version, either in the new 'experimental' branch, or directly against the upstream kernel. 8. Any customers still using the experimental version of the feature will need to update their code to work with the upstream version in order to update to the new (supported) 'experimental' branch, or to the upstream kernel. =========================== What does this mean for me? =========================== ...as a user? ------------- If you're using the upstream version of KUnit, nothing! Features will continue to be pushed upstream when they're ready. If you're using the 'kunit/alpha/master' branch, then you'll need to switch to the new 'experimental-<version>' branches. Every so often, we'll create a new 'experimental-<version>' branch, and you'll need to rebase your code on top of that to keep receiving updated features and bugfixes. While we intend to make this as painless as possible, there may be breaking changes which require you to rework some of your tests. Once a feature exists in the upstream kernel, the version of that feature in the 'experimental' branches should stabilise somewhat. ...as a KUnit developer? ------------------------ For most changes/bugfixes which apply cleanly to the upstream version, you should directly submit these upstream as before. If it is feasible and useful to backport them to the latest 'experimental' branch (e.g., they are bugfixes to code that the experimental branch already has), please do so. For more major features (or anything which depends on yet-to-be-upstreamed code), you should develop them in the latest 'experimental' branch. For the most part, you can treat this the same way as the old 'kunit/alpha/master' branch, but note that changes will need to be rebased on top of a newer experimental branch periodically. It may make sense to use this as an opportunity to tidy the code up somewhat: by removing compatibility code for deprecated features, or to merge 'fixup' commits. Once the code has been upstreamed, the next rebase of the 'experimental' branch should only use the upstream version: there should not be a separate 'experimental' version of upstream code save for the development of a new 'experimental' feature or bugfix. For more details, see the 'Lifetime of a feature' section above. ============= In Conclusion ============= We'll continue to be working with upstream as before, but we intend to rename and more explicitly specify the purpose of the 'kunit/alpha/master' branch as above. This will require a bit more work from people using and developing against this 'experimental' branch, but allows us to continue to use it for features such as the mocking framework while limiting its divergence from upstream. Do let us know if this sounds reasonable to you, if it will affect your use case, or if you have any questions. Cheers, -- David & Brendan [1] https://kunit.googlesource.com/linux/+/refs/heads/kunit/alpha/master [2] https://kunit.googlesource.com/linux/+/kunit/alpha/master/Documentation/tes…

[PATCH v17 00/19] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Linus[1] and Randy[2], by moving top level `kunit/` directory to `lib/kunit/` and likewise moves top level Kconfig entry under lib/Kconfig.debug, so the KUnit submenu now shows up under the "Kernel Hacking" menu. As a consequence of this, I rewrote patch 06/18 (kbuild: enable building KUnit), and now needs to be re-acked/reviewed. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[3]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[4]. Additionally for convenience, I have applied these patches to a branch[5]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/initial/v5.3/v17 branch. ## History since v15 ### v17 - Addressed comments on 06/19 (lib: enable building KUnit in lib/) from Stephen Boyd by moving KUnit submenu ahead of Runtime Testing submenu. ### v16 - Addressed comments from Linus Torvalds by moving all kunit/ paths to lib/kunit/. - Addressed comments by Randy Dunlap by moving KUnit Kconfig under lib/Kconfig.debug so the KUnit submenu shows up under the "Kernel Hacking" menu.

[RFC v3 00/19] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in under a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ## What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ## Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ## More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here: https://google.github.io/kunit-docs/third_party/kernel/docs/ Additionally for convenience, I have applied these patches to a branch: https://kunit.googlesource.com/linux/+/kunit/rfc/4.19/v3 The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/4.19/v3 branch. ## Changes Since Last Version - Changed namespace prefix from `test_*` to `kunit_*` as requested by Shuah. - Started converting/cleaning up the device tree unittest to use KUnit. - Started adding KUnit expectations with custom messages. -- 2.20.0.rc0.387.gc7a69e6b6c-goog

[PATCH v16 00/19] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Linus[1] and Randy[2], by moving top level `kunit/` directory to `lib/kunit/` and likewise moves top level Kconfig entry under lib/Kconfig.debug, so the KUnit submenu now shows up under the "Kernel Hacking" menu. As a consequence of this, I rewrote patch 06/18 (kbuild: enable building KUnit), and now needs to be re-acked/reviewed. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[3]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++.

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

by Kees Cook

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).

Re: [GIT PULL] Kselftest update for Linux 5.4-rc1

On Tue, Sep 17, 2019 at 12:26 PM Shuah Khan <skhan(a)linuxfoundation.org> wrote: > > This Kselftest update for Linux 5.4-rc1 consists of several fixes to > existing tests and adds KUnit, a lightweight unit testing and mocking > framework for the Linux kernel from Brendan Higgins. So I pulled this, but then I almost immediately unpulled it. My reason for doing that may be odd, but it's because of the top-level 'kunit' directory. This shouldn't be on the top level. The reason I react so strongly is that it actually breaks my finger memory. I don't type out filenames - I auto-compete them. So "kernel/" is "k<tab>", "drivers/" is "d<tab>" etc. It already doesn't work for everything ("mm/" is actually "mm<tab>" not because we have files in the git tree, but because the build creates various "module" files), but this breaks a common pattern for me. > In the future KUnit will be linked to Kselftest framework to provide > a way to trigger KUnit tests from user-space. Can the kernel parts please move to lib/kunit/ or something like that? Linus

[PATCH v1 0/3] seccomp: continue syscall from notifier

by Christian Brauner

Hey everyone, This is the patchset coming out of the KSummit session Kees and I gave in Lisbon last week (cf. [3] which also contains slides with more details on related things such as deep argument inspection). The simple idea is to extend the seccomp notifier to allow for the continuation of a syscall. The rationale for this can be found in the commit message to [1]. For the curious there is more detail in [2]. This patchset would unblock supervising an extended set of syscalls such as mount() where a privileged process is supervising the syscalls of a lesser privileged process and emulates the syscall for the latter in userspace. For more comments on security see [1].

[PATCH v4 0/9] hugetlb_cgroup: Add hugetlb_cgroup reservation limits

by Mina Almasry

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. - 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, with tests to verify functionality and show the usage. Alternatives considered: 1. A new cgroup, instead of only a new page_counter attached to the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code duplication with hugetlb_cgroup. Keeping hugetlb related page counters under hugetlb_cgroup seemed cleaner as well. 2. Instead of adding a new counter, we considered adding a sysctl that modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at reservation time rather than fault time. Adding a new page_counter seems better as userspace could, if it wants, choose to enforce different cgroups differently: one via limit_in_bytes, and another via reservation_limit_in_bytes. This could be very useful if you're transitioning how hugetlb memory is partitioned on your system one cgroup at a time, for example. Also, someone may find usage for both limit_in_bytes and reservation_limit_in_bytes concurrently, and this approach gives them the option to do so. Caveats: 1. This support is implemented for cgroups-v1. I have not tried hugetlb_cgroups with cgroups v2, and AFAICT it's not supported yet. This is largely because we use cgroups-v1 for now. If required, I can add hugetlb_cgroup support to cgroups v2 in this patch or a follow up. 2. Most complicated bit of this patch I believe is: where to store the pointer to the hugetlb_cgroup to uncharge at unreservation time? Normally the cgroup pointers hang off the struct page. But, with hugetlb_cgroup reservations, one task can reserve a specific page and another task may fault it in (I believe), so storing the pointer in struct page is not appropriate. Proposed approach here is to store the pointer in the resv_map. See patch for details.

[PATCH v12 00/12] namei: openat2(2) path resolution restrictions

by Aleksa Sarai

This patchset is being developed here: <https://github.com/cyphar/linux/tree/resolveat/master> Patch changelog: v12: * Remove @how->reserved field from openat2(2), and instead use the (struct, size) design for syscall extensions. * Implement copy_struct_{to,from}_user() to unify (struct, size) syscall extension designs (as well as make them slightly more efficient by using memchr_inv() as well as using buffers and avoiding repeated access_ok() checks for trailing byte operations). * Port sched_setattr(), perf_event_attr(), and clone3() to use the new helpers. 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/> 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[1,2] patchset (which was a variant of David Drysdale's O_BENEATH patchset[3] which was a spin-off of the Capsicum project[4]) with a few additions and changes made based on the previous discussion within [5] 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. * 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. * 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[6] 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). And further, several semantics of file descriptor "re-opening" are now changed to prevent attacks like CVE-2019-5736 by restricting how magic-links can be resolved (based on their mode). This required some other changes to the semantics of the modes of O_PATH file descriptor's associated /proc/self/fd magic-links. openat2(2) has the ability to further restrict re-opening of its own O_PATH fds, so that users can make even better use of this feature. Finally, O_EMPTYPATH was added so that users can do /proc/self/fd-style re-opening without depending on procfs. The new restricted semantics for magic-links are applied here too. In order to make all of the above more usable, I'm working on libpathrs[7] 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.

[PATCH v2] selftests: watchdog: Validate optional file argument

by George G. Davis

As reported by Eugeniu Rosca, a side of affect of commit c3f2490d6e92 ("selftests: watchdog: Add optional file argument") is that arbitrary files may be opened for watchdog testing, e.g. ./watchdog-test -f /dev/zero Watchdog Ticking Away! To prevent watchdog-test from operating on non-watchdog device files, validate that a file is indeed a watchdog device via an ioctl(WDIOC_GETSUPPORT) call. While we're at it, since the watchdog_info is available as a result of the ioctl(WDIOC_GETSUPPORT) call, add a command line option to optionally show the watchdog_info.

Hello. This patch set updates clone3 selftest in several aspects: - adding a check for kernel not ignoring highest 32 bits of exit_signal field of clone3 syscall arguments structure; - adding clone3 to selftests targets; - enabling clone3 tests on all architectures; - minor cleanups of the clone3 test.

[PATCH v5 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. A common internal test-case layout is proposed which then it is anyway wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. This series converts also to this subdirectory scheme the pre-existing (already queued on arm64/for-next/core) KSFT arm64 tags tests, moving them into arm64/tags. Thanks Cristian Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas for more TODO testcases: - fake_sigreturn_unmapped_sp: SP into unmapped addrs - fake_sigreturn_kernelspace_sp: SP into kernel addrs - fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed - mangle_sve_invalid_extra_context: SVE extra_context invalid - SVE signal testcases and special handling will be part of an additional patch still to be released - KSFT arm64 tags test patch https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300… is relocated into its own directory under tools/testing/selftests/arm64/tags Changes: -------- v4-->v5: - rebased on arm64/for-next-core merging 01/11 with KSFT tags tests commmit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel") - moved .gitignore up on elevel - moved kernel header search mechanism into KSFT arm64 toplevel Makefile so that it can be used easily also by each arm64 KSFT subsystem inside subdirs of arm64 v3-->v4: - rebased on v5.3-rc6 - added test descriptions - fixed commit messages (imperative mood) - added missing includes and removed unneeded ones - added/used new get_starting_head() helper - fixed/simplified signal.S::fakke_sigreturn() - added set_regval() macro and .init initialization func - better synchonization in get_current_context() - macroization of mangle_pstate_invalid_mode_el - splitted mangle_pstate_invalid_mode_el h/t - removed standalone mode - simplified CPU features checks - fixed/refactored get_header() and validation routines - simplfied docs v2-->v3: - rebased on v5.3-rc2 - better test result characterization looking for SEGV_ACCERR in si_code on SIGSEGV - using KSFT Framework macros for retvalues - removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused - reviewed generation process of test_arm64_signals.sh runner script - re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly extended fake_sigreturn() helper - added tests' TODO notes v1-->v2: - rebased on 5.2-rc7 - various makefile's cleanups - mixed READMEs fixes - fixed test_arm64_signals.sh runner script - cleaned up assembly code in signal.S - improved get_current_context() logic - fixed SAFE_WRITE() - common support code splitted into more chunks, each one introduced when needed by some new testcases - fixed some headers validation routines in testcases.c - removed some still broken/immature tests: + fake_sigreturn_misaligned + fake_sigreturn_overflow_reserved + mangle_pc_invalid + mangle_sp_misaligned - fixed some other testcases: + mangle_pstate_ssbs_regs: better checks of SSBS bit when feature unsupported + mangle_pstate_invalid_compat_toggle: name fix + mangle_pstate_invalid_mode_el[1-3]: precautionary zeroing PSTATE.MODE + fake_sigreturn_bad_magic, fake_sigreturn_bad_size, fake_sigreturn_bad_size_for_magic0: -

[RFC bpf-next 0/7] bpf: packet capture helpers, bpftool support

by Alan Maguire

Packet capture is useful from a general debugging standpoint, and is useful in particular in debugging BPF programs that do packet processing. For general debugging, being able to initiate arbitrary packet capture from kprobes and tracepoints is highly valuable; e.g. what do the packets that reach kfree_skb() - representing error codepaths - look like? Arbitrary packet capture is distinct from the traditional concept of pre-defined hooks, and gives much more flexibility in probing system behaviour. For packet-processing BPF programs, packet capture can be useful for doing things such as debugging checksum errors. The intent of this RFC patchset is to initiate discussion on if and how to work packet capture-specific capabilities into BPF. It is possible - and indeed projects like xdpcap [1] have demonstrated how - to carry out packet capture in BPF today via perf events, but the aim here is to simplify both the in-BPF capture and the userspace collection. The suggested approach is to add a new bpf helper - bpf_pcap() - to simplify packet capture within BPF programs, and to enhance bpftool to add a "pcap" subcommand to aid in retrieving packets. The helper is for the most part a wrapper around perf event sending, using data relevant for packet capture as metadata. The end result is being able to capture packet data in the following manner. For example if we add an iptables drop rule, we can observe TCP SYN segments being freed at kfree_skb: $ iptables -A INPUT -p tcp --dport 6666 -j DROP $ bpftool pcap trace kprobe:kfree_skb proto ip data_out /tmp/cap & $ nc 127.0.0.1 6666 Ncat: Connection timed out. $ fg ^C $ tshark -r /tmp/cap Running as user "root" and group "root". This could be dangerous. ... 3 7 127.0.0.1 -> 127.0.0.1 TCP 60 54732 > ircu [SYN] Seq=0 Win=65495 Len=0 MSS=65495 SACK_PERM=1 TSval=696475539 TSecr=0 WS=128 ... Tracepoints are also supported, and by default data is sent to stdout, so we can pipe to tcpdump: $ bpftool pcap trace tracepoint:net_dev_xmit:arg1 proto eth | tcpdump -r - reading from file -, link-type EN10MB (Ethernet) 00:16:49.150880 IP 10.11.12.13 > 10.11.12.14: ICMP echo reply, id 10519, seq 1, length 64 ... Patch 1 adds support for bpf_pcap() in skb and XDP programs. In those cases, the argument is the relevant context (struct __sk_buff or xdp metadata) from which we capture. Patch 2 extends the helper to allow it to work for tracing programs, and in that case the data argument is a pointer to an skb, derived from raw tracepoint or kprobe arguments. Patch 3 syncs uapi and tools headers for the new helper, flags and associated pcap header type. Patch 4 adds a feature test for libpcap which will be used in the next patch. Patch 5 adds a "pcap" subcommand to bpftool to collect packet data from BPF-driven perf event maps in existing programs. Also supplied are simple tracepoint and kprobe programs which can be used to attach to a kprobe or raw tracepoint to retrieve arguments and capture the associated skb. Patch 6 adds documentation for the new pcap subcommand. Patch 7 tests the pcap subcommand for tracing, skb and xdp programs.

[RFC 00/19] Integration of Kernel Test Framework (KTF) into the kernel tree

by Knut Omang

KTF has already been available for a while as a separate git repository with means to facilitate use with any kernel version. KTF can be used both for "pure" unit testing and for more pragmatic approaches to component testing. Apart from some useful features that KTF uses from the kernel toolbox (such as kallsyms, kprobes), KTF does not depend on any special environment such as UML or on a large set of mocked up APIs to be useful. KTF basically allows test code to be inserted and managed as separate kernel modules, while providing the tests convenient access to almost the full range of kernel APIs, both exposed and private. And once a KTF test set exists, it should be fairly easy to compile and run it against older versions of the kernel as well. This series proposes a non-intrusive integration of KTF into the kernel hopefully presented in digestable pieces. For convenience, the patch set is also available on top of v5.2 at https://github.com/knuto/linux/pull/new/ktf_v1 . The high level structure of the KTF code is as follows: External dependencies for the user land side: * libnl3 for netlink communication * googletest for test runner, reporting and test selection support. Kernel components: * Simple core test and test suite related abstractions: core data structures ktf_case, ktf_test, an assertion macro "infrastructure" with ASSERT_* and EXPECT_* macros and helper functions * Bookkeeping data structures: - ktf_map - a (key, value) mapping container used to implement management of instances of the higher level abstraction needs, such as ktf_handle and ktf_context. - ktf_handle: A global environment that a test runs within. - ktf_context: a test suite specific abstraction to allow a test to execute within one or more contexts. An example use of context can be a device instance: A test can be instantiated to run on all available such devices, according to test suite defined criteria. * A generic netlink protocol (ktf_nl, ktf_unlproto) which defines operations to allow a user space part of a test to query the kernel for test information, invoke tests and get feedback reports about results. * An alternative debugfs interface to allow examining and executing kernel-only tests without a user level program. * Support for overriding and modifying behaviour of kernel calls. User mode components: * A test executor based on and integrated with Googletest. Googletest is one of several mature user land unit test suites for C/C++. The choice allowed us to focus on kernel specific functionality rather than having to reinvent too many wheels. * Tools to aid in creating new test modules (suites): To facilitate a developer friendly way of testing internals of a module or the kernel itself, one of the important features of KTF, we often need to access symbols deliberately not exposed from a module. KTF contains a script used to create definitions based on kallsyms lookup for easy access to symbols not exposed by a module or the kernel. The user just provides a simple text file with a list of the symbols by module. This series is an attempt to address feedback from several people that having the functionality readily available within the kernel repository is desired. An in-tree KTF allows test suites to be provided with the kernel, which makes it easy to use KTF based suites as part of the kernel selftests and driver test suites. Having the ability to still build and run the latest versions of test suites against older kernels should be of great value to stable maintainers, distributions and driver maintainers, who would want to have an easy path, with minimal backporting efforts to make sure that criterias implemented by new test logic is also valid for these kernels. Our definite goal moving forward is to try to satisfy both needs in a transparent way. The plan is to let the standalone KTF repository follow the in-kernel one, and to allow test suites to be maintained similarly, and to support maintenance by proper tooling. Mode of integration into the kernel =================================== One feature of KTF is that it allows tests to work, look and feel similar whether they execute entirely in user mode, entirely in kernel mode, or half and half (hybrid tests). KTF consist of both user space and kernel code. Unlike e.g. kselftest, KTF in the Github version does not attempt to address the test runner aspects of testing. Due to the need for building modules, KTF requires access to kernel module build facilities (obj-m). But KTF also has nontrivial needs for user land building, and we think it is good to keep the build structure in a way that allows KTF to be built both in-tree and out-of-tree without necessarily having to reconfigure the kernel. This first version of kernel integration of KTF solves this challenge by co-locating everything associated with KTF under ktf/ as in the github version, but use the little used hostprogs-y and hostlibs-y features to build the user space side. The first patch in the series is fixes to make it work in a natural way to suit our needs. Positioning for natural building within the kernel tree ======================================================= Currently we find significant amount of C level tests within the following paths: tools/testing/selftests/ (kselftests, almost entirely user space so far) lib/ (various kernel level mostly unit tests) and in the making:: kunit/ (kernel only (UML)) So all kernel code are currently located directly within the kernel build paths, accessed from the top level Makefile, to allow everything to be controlled by config and from the main build targets for the kernel. But this also poses challenges, in that .config has to be modified to build tests. And once a .config is changed, we no longer in principle logically operate on the same kernel. A better approach seems to be to follow the principle taken by kselftest: To have all the logic associated with the test inside the test tree, and make it available for building separately from the kernel itself. This require us to have a means to build kernel modules from within the test tree, separately from the main kernel paths. Currently this seems to only by supported via the M= option used to build out-of-tree modules. This was also easy to get to work for the kernel parts, based on the Github version of KTF, where we already do this. With the additional need to compile user land code, using the corresponding hostprogs-y and hostNNlibs-y seemed natural, but this has been challenging: The build macros does not really support hostprogs-y etc as "first class citizens" so some amount of hacking is in there in this first draft version. Using hostprogs-y etc is also a different approach that what is used for C code in kselftest today, but we imagine that there's room for unification here to get the best of both worlds, with the help of the wider Kbuild community. As an initial proposal, we have positioned ktf as an additional kselftest target, under tools/testing/selftests/ktf, and the recommended: make TARGETS="ktf" kselftest way of building and running should work, even from normal user accounts, if the user running it has sudo rights (for the kernel module insertion and removal). This will run the selftests for KTF itself, and should be a good starting point for adding more test cases. We also have had activities going to take some of the existing test suites under lib/ and convert them into KTF based test suites, and will get back to this later. A trimmed down output from the above make target would look like this: ...

[PATCH ARM64] selftests, arm64: add kernel headers path for tags_test

by Andrey Konovalov

tags_test.c relies on PR_SET_TAGGED_ADDR_CTRL/PR_TAGGED_ADDR_ENABLE being present in system headers. When this is not the case the build of this test fails with undeclared identifier errors.

[PATCH v3 0/6] hugetlb_cgroup: Add hugetlb_cgroup reservation limits

by Mina Almasry

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. - 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, with tests to verify functionality and show the usage. Alternatives considered: 1. A new cgroup, instead of only a new page_counter attached to the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code duplication with hugetlb_cgroup. Keeping hugetlb related page counters under hugetlb_cgroup seemed cleaner as well. 2. Instead of adding a new counter, we considered adding a sysctl that modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at reservation time rather than fault time. Adding a new page_counter seems better as userspace could, if it wants, choose to enforce different cgroups differently: one via limit_in_bytes, and another via reservation_limit_in_bytes. This could be very useful if you're transitioning how hugetlb memory is partitioned on your system one cgroup at a time, for example. Also, someone may find usage for both limit_in_bytes and reservation_limit_in_bytes concurrently, and this approach gives them the option to do so. Caveats: 1. This support is implemented for cgroups-v1. I have not tried hugetlb_cgroups with cgroups v2, and AFAICT it's not supported yet. This is largely because we use cgroups-v1 for now. If required, I can add hugetlb_cgroup support to cgroups v2 in this patch or a follow up. 2. Most complicated bit of this patch I believe is: where to store the pointer to the hugetlb_cgroup to uncharge at unreservation time? Normally the cgroup pointers hang off the struct page. But, with hugetlb_cgroup reservations, one task can reserve a specific page and another task may fault it in (I believe), so storing the pointer in struct page is not appropriate. Proposed approach here is to store the pointer in the resv_map. See patch for details. Signed-off-by: Mina Almasry <almasrymina(a)google.com> [1]: https://www.kernel.org/doc/html/latest/vm/hugetlbfs_reserv.html 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 v18 00/15] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

=== Overview arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a tagged pointer") 2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged pointers") 3. 276e9327 ("arm64: entry: improve data abort handling of tagged pointers") This patchset extends tagged pointer support to syscall arguments. As per the proposed ABI change [3], tagged pointers are only allowed to be passed to syscalls when they point to memory ranges obtained by anonymous mmap() or sbrk() (see the patchset [3] for more details). For non-memory syscalls this is done by untaging user pointers when the kernel performs pointer checking to find out whether the pointer comes from userspace (most notably in access_ok). The untagging is done only when the pointer is being checked, the tag is preserved as the pointer makes its way through the kernel and stays tagged when the kernel dereferences the pointer when perfoming user memory accesses. The mmap and mremap (only new_addr) syscalls do not currently accept tagged addresses. Architectures may interpret the tag as a background colour for the corresponding vma. Other memory syscalls (mprotect, etc.) don't do user memory accesses but rather deal with memory ranges, and untagged pointers are better suited to describe memory ranges internally. Thus for memory syscalls we untag pointers completely when they enter the kernel. === Other approaches One of the alternative approaches to untagging that was considered is to completely strip the pointer tag as the pointer enters the kernel with some kind of a syscall wrapper, but that won't work with the countless number of different ioctl calls. With this approach we would need a custom wrapper for each ioctl variation, which doesn't seem practical. An alternative approach to untagging pointers in memory syscalls prologues is to inspead allow tagged pointers to be passed to find_vma() (and other vma related functions) and untag them there. Unfortunately, a lot of find_vma() callers then compare or subtract the returned vma start and end fields against the pointer that was being searched. Thus this approach would still require changing all find_vma() callers. === Testing The following testing approaches has been taken to find potential issues with user pointer untagging: 1. Static testing (with sparse [2] and separately with a custom static analyzer based on Clang) to track casts of __user pointers to integer types to find places where untagging needs to be done. 2. Static testing with grep to find parts of the kernel that call find_vma() (and other similar functions) or directly compare against vm_start/vm_end fields of vma. 3. Static testing with grep to find parts of the kernel that compare user pointers with TASK_SIZE or other similar consts and macros. 4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running a modified syzkaller version that passes tagged pointers to the kernel. Based on the results of the testing the requried patches have been added to the patchset. === Notes This patchset is meant to be merged together with "arm64 relaxed ABI" [3]. This patchset is a prerequisite for ARM's memory tagging hardware feature support [4]. This patchset has been merged into the Pixel 2 & 3 kernel trees and is now being used to enable testing of Pixel phones with HWASan. Thanks!

There is some minor clean-up as well". Changes in v17: - The "uaccess: add noop untagged_addr definition" patch is dropped, as it was merged into upstream named as "uaccess: add noop untagged_addr definition". - Merged "mm, arm64: untag user pointers in do_pages_move" into "mm, arm64: untag user pointers passed to memory syscalls". - Added "arm64: Introduce prctl() options to control the tagged user addresses ABI" patch from Catalin. - Add tags_lib.so to tools/testing/selftests/arm64/.gitignore. - Added a comment clarifying untagged in mremap. - Moved untagging back into mlx4_get_umem_mr() for the IB patch. Changes in v16: - Moved untagging for memory syscalls from arm64 wrappers back to generic code. - Dropped untagging for the following memory syscalls: brk, mmap, munmap; mremap (only dropped for new_address); mmap_pgoff (not used on arm64); remap_file_pages (deprecated); shmat, shmdt (work on shared memory). - Changed kselftest to LD_PRELOAD a shared library that overrides malloc to return tagged pointers. - Rebased onto 5.2-rc3. Changes in v15: - Removed unnecessary untagging from radeon_ttm_tt_set_userptr(). - Removed unnecessary untagging from amdgpu_ttm_tt_set_userptr(). - Moved untagging to validate_range() in userfaultfd code. - Moved untagging to ib_uverbs_(re)reg_mr() from mlx4_get_umem_mr(). - Rebased onto 5.1. Changes in v14: - Moved untagging for most memory syscalls to an arm64 specific implementation, instead of doing that in the common code. - Dropped "net, arm64: untag user pointers in tcp_zerocopy_receive", since the provided user pointers don't come from an anonymous map and thus are not covered by this ABI relaxation. - Dropped "kernel, arm64: untag user pointers in prctl_set_mm*". - Moved untagging from __check_mem_type() to tee_shm_register(). - Updated untagging for the amdgpu and radeon drivers to cover the MMU notifier, as suggested by Felix. - Since this ABI relaxation doesn't actually allow tagged instruction pointers, dropped the following patches: - Dropped "tracing, arm64: untag user pointers in seq_print_user_ip". - Dropped "uprobes, arm64: untag user pointers in find_active_uprobe". - Dropped "bpf, arm64: untag user pointers in stack_map_get_build_id_offset". - Rebased onto 5.1-rc7 (37624b58). Changes in v13: - Simplified untagging in tcp_zerocopy_receive(). - Looked at find_vma() callers in drivers/, which allowed to identify a few other places where untagging is needed. - Added patch "mm, arm64: untag user pointers in get_vaddr_frames". - Added patch "drm/amdgpu, arm64: untag user pointers in amdgpu_ttm_tt_get_user_pages". - Added patch "drm/radeon, arm64: untag user pointers in radeon_ttm_tt_pin_userptr". - Added patch "IB/mlx4, arm64: untag user pointers in mlx4_get_umem_mr". - Added patch "media/v4l2-core, arm64: untag user pointers in videobuf_dma_contig_user_get". - Added patch "tee/optee, arm64: untag user pointers in check_mem_type". - Added patch "vfio/type1, arm64: untag user pointers". Changes in v12: - Changed untagging in tcp_zerocopy_receive() to also untag zc->address. - Fixed untagging in prctl_set_mm* to only untag pointers for vma lookups and validity checks, but leave them as is for actual user space accesses. - Updated the link to the v2 of the "arm64 relaxed ABI" patchset [3]. - Dropped the documentation patch, as the "arm64 relaxed ABI" patchset [3] handles that. Changes in v11: - Added "uprobes, arm64: untag user pointers in find_active_uprobe" patch. - Added "bpf, arm64: untag user pointers in stack_map_get_build_id_offset" patch. - Fixed "tracing, arm64: untag user pointers in seq_print_user_ip" to correctly perform subtration with a tagged addr. - Moved untagged_addr() from SYSCALL_DEFINE3(mprotect) and SYSCALL_DEFINE4(pkey_mprotect) to do_mprotect_pkey(). - Moved untagged_addr() definition for other arches from include/linux/memory.h to include/linux/mm.h. - Changed untagging in strn*_user() to perform userspace accesses through tagged pointers. - Updated the documentation to mention that passing tagged pointers to memory syscalls is allowed. - Updated the test to use malloc'ed memory instead of stack memory. Changes in v10: - Added "mm, arm64: untag user pointers passed to memory syscalls" back. - New patch "fs, arm64: untag user pointers in fs/userfaultfd.c". - New patch "net, arm64: untag user pointers in tcp_zerocopy_receive". - New patch "kernel, arm64: untag user pointers in prctl_set_mm*". - New patch "tracing, arm64: untag user pointers in seq_print_user_ip". Changes in v9: - Rebased onto 4.20-rc6. - Used u64 instead of __u64 in type casts in the untagged_addr macro for arm64. - Added braces around (addr) in the untagged_addr macro for other arches. Changes in v8: - Rebased onto 65102238 (4.20-rc1). - Added a note to the cover letter on why syscall wrappers/shims that untag user pointers won't work. - Added a note to the cover letter that this patchset has been merged into the Pixel 2 kernel tree. - Documentation fixes, in particular added a list of syscalls that don't support tagged user pointers. Changes in v7: - Rebased onto 17b57b18 (4.19-rc6). - Dropped the "arm64: untag user address in __do_user_fault" patch, since the existing patches already handle user faults properly. - Dropped the "usb, arm64: untag user addresses in devio" patch, since the passed pointer must come from a vma and therefore be untagged. - Dropped the "arm64: annotate user pointers casts detected by sparse" patch (see the discussion to the replies of the v6 of this patchset). - Added more context to the cover letter. - Updated Documentation/arm64/tagged-pointers.txt. Changes in v6: - Added annotations for user pointer casts found by sparse. - Rebased onto 050cdc6c (4.19-rc1+). Changes in v5: - Added 3 new patches that add untagging to places found with static analysis. - Rebased onto 44c929e1 (4.18-rc8). Changes in v4: - Added a selftest for checking that passing tagged pointers to the kernel succeeds. - Rebased onto 81e97f013 (4.18-rc1+). Changes in v3: - Rebased onto e5c51f30 (4.17-rc6+). - Added linux-arch@ to the list of recipients. Changes in v2: - Rebased onto 2d618bdf (4.17-rc3+). - Removed excessive untagging in gup.c. - Removed untagging pointers returned from __uaccess_mask_ptr. Changes in v1: - Rebased onto 4.17-rc1. Changes in RFC v2: - Added "#ifndef untagged_addr..." fallback in linux/uaccess.h instead of defining it for each arch individually. - Updated Documentation/arm64/tagged-pointers.txt. - Dropped "mm, arm64: untag user addresses in memory syscalls". - Rebased onto 3eb2ce82 (4.16-rc7).

[PATCH v3 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. A common internal test-case layout is proposed which then it is anyway wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. arm64/signal tests can be run via KSFT or standalone. Thanks Cristian Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas in testcases/TODO.readme - a bit of overlap around KSFT arm64/ Makefiles is expected with this: https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300… Changes: -------- v2-->v3: - rebased on v5.3-rc2 - better test result characterization looking for SEGV_ACCERR in si_code on SIGSEGV - using KSFT Framework macros for retvalues - removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused - reviewed generation process of test_arm64_signals.sh runner script - re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly extended fake_sigreturn() helper -

Previously KUnit assumed that printk would always be present, which is not a valid assumption to make. Fix that by removing call to vprintk_emit, and calling printk directly. This fixes a build error[1] reported by Randy. For context this change comes after much discussion. My first stab[2] at this was just to make the KUnit logging code compile out; however, it was agreed that if we were going to use vprintk_emit, then vprintk_emit should provide a no-op stub, which lead to my second attempt[3]. In response to me trying to stub out vprintk_emit, Sergey Senozhatsky suggested a way for me to remove our usage of vprintk_emit, which led to my third attempt at solving this[4]. In my third version of this patch[4], I completely removed vprintk_emit, as suggested by Sergey; however, there was a bit of debate over whether Sergey's solution was the best. The debate arose due to Sergey's version resulting in a checkpatch warning, which resulted in a debate over correct printk usage. Joe Perches offered an alternative fix which was somewhat less far reaching than what Sergey had suggested and importantly relied on continuing to use %pV. Much of the debated centered around whether %pV should be widely used, and whether Sergey's version would result in object size bloat. Ultimately, we decided to go with Sergey's version.

Automated Testing devroom at FOSDEM 2020 poll

by Anders Roxell

Hello everyone, We are planning to put together a Automated Testing devroom at FOSDEM 2020 [1] and would like to see if there is any interest in attending such an event. If we're not able to put together a set of talks that fills up a (half) day we shouldn't apply for a devroom. We have a few people prepared to give talks if the devroom happens. We would like to know your interest in attending (or, better yet, make a proposal to speak or for a discussion session) before 16 September. Cheers, Anders [1] https://fosdem.org/2020/

[PATCH v2] kunit: fix failure to build without printk

Some systems have multiple watchdog devices where the first device registered is assigned to the /dev/watchdog device file. In order to test other watchdog devices, add an optional file argument for selecting non-default watchdog devices for testing.

[PATCH v4 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. A common internal test-case layout is proposed which then it is anyway wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. arm64/signal tests can be run via KSFT or standalone. Thanks Cristian Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas for more TODO testcases: - fake_sigreturn_unmapped_sp: SP into unmapped addrs - fake_sigreturn_kernelspace_sp: SP into kernel addrs - fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed - mangle_sve_invalid_extra_context: SVE extra_context invalid - SVE signal testcases and special handling will be part of an additional patch still to be released Changes: -------- v3-->v4: - rebased on v5.3-rc6 - added test descriptions - fixed commit messages (imperative mood) - added missing includes and removed unneeded ones - added/used new get_starting_head() helper - fixed/simplified signal.S::fakke_sigreturn() - added set_regval() macro and .init initialization func - better synchonization in get_current_context() - macroization of mangle_pstate_invalid_mode_el - splitted mangle_pstate_invalid_mode_el h/t - removed standalone mode - simplified CPU features checks - fixed/refactored get_header() and validation routines - simplfied docs v2-->v3: - rebased on v5.3-rc2 - better test result characterization looking for SEGV_ACCERR in si_code on SIGSEGV - using KSFT Framework macros for retvalues - removed SAFE_WRITE()/dump_uc: buggy, un-needed and unused - reviewed generation process of test_arm64_signals.sh runner script - re-added a fixed fake_sigreturn_misaligned_sp testcase and a properly extended fake_sigreturn() helper - added tests' TODO notes v1-->v2: - rebased on 5.2-rc7 - various makefile's cleanups - mixed READMEs fixes - fixed test_arm64_signals.sh runner script - cleaned up assembly code in signal.S - improved get_current_context() logic - fixed SAFE_WRITE() -

[PATCH] selftests/seccomp: fix build on older kernels

by Tycho Andersen

The seccomp selftest goes to some length to build against older kernel headers, viz. all the #ifdefs at the beginning of the file. 201766a20e30 ("ptrace: add PTRACE_GET_SYSCALL_INFO request") introduces some additional macros, but doesn't do the #ifdef dance. Let's add that dance here to avoid: gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf In file included from seccomp_bpf.c:51: seccomp_bpf.c: In function ‘tracer_ptrace’: seccomp_bpf.c:1787:20: error: ‘PTRACE_EVENTMSG_SYSCALL_ENTRY’ undeclared (first use in this function); did you mean ‘PTRACE_EVENT_CLONE’?

[PATCH RESEND v11 0/8] openat2(2)

by Aleksa Sarai

This patchset is being developed here: <https://github.com/cyphar/linux/tree/resolveat/master> Patch changelog: v11: [RESEND: <https://lore.kernel.org/lkml/20190728010207.9781-1-cyphar@cyphar.com/>] * Fix checkpatch.pl errors and warnings where reasonable. * Minor cleanup to pr_warn logging for may_open_magiclink(). * Drop kselftests patch to handle %m formatting correctly, and send it through the kselftests tree directly.

This patchset is a revival of Al Viro's old AT_NO_JUMPS[1,2] patchset (which was a variant of David Drysdale's O_BENEATH patchset[3] which was a spin-off of the Capsicum project[4]) with a few additions and changes made based on the previous discussion within [5] 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. * 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. * 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[6] 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). And further, several semantics of file descriptor "re-opening" are now changed to prevent attacks like CVE-2019-5736 by restricting how magic-links can be resolved (based on their mode). This required some other changes to the semantics of the modes of O_PATH file descriptor's associated /proc/self/fd magic-links. openat2(2) has the ability to further restrict re-opening of its own O_PATH fds, so that users can make even better use of this feature. Finally, O_EMPTYPATH was added so that users can do /proc/self/fd-style re-opening without depending on procfs. The new restricted semantics for magic-links are applied here too. In order to make all of the above more usable, I'm working on libpathrs[7] 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.

[PATCH v1] sefltest/ima: support appended signatures (modsig)

by Mimi Zohar

In addition to the PE/COFF and IMA xattr signatures, the kexec kernel image can be signed with an appended signature, using the same scripts/sign-file tool that is used to sign kernel modules. This patch adds support for detecting a kernel image signed with an appended signature and updates the existing test messages appropriately.

[PATCH v1] printk: add dummy vprintk_emit for when CONFIG_PRINTK=n

by Brendan Higgins

Previously vprintk_emit was only defined when CONFIG_PRINTK=y, this caused a build failure in kunit/test.c when CONFIG_PRINTK was not set. Add a no-op dummy so that callers don't have to ifdef around this. Note: It has been suggested that this go in through the kselftest tree along with the KUnit patches, because KUnit depends on this. See the second link for the discussion on this.

[PATCH v1] kunit: fix failure to build without printk

by Brendan Higgins

Previously KUnit assumed that printk would always be present, which is not a valid assumption to make. Fix that by ifdefing out functions which directly depend on printk core functions similar to what dev_printk does.

[PATCH] doc: kselftest: update for clarity on running kselftests in CI rings

[PATCH v15 00/18] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Shuah by fixing a couple checkpatch warnings and fixing some comment readability issues. No API or major structual changes have been made since v13. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[1]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[2]. Additionally for convenience, I have applied these patches to a branch[3]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/v5.3/v15 branch. ## Changes Since Last Version - Moved comment from inline in macro to kernel-doc to address checkpatch warning. - Demoted BUG() to WARN_ON. - Formatted some kernel-doc comments to make them more readible.

[PATCH 0/3] firmware: selftest for request_firmware_into_buf

by Scott Branden

This patch series adds kernel selftest of request_firmware_into_buf. The API was added to the kernel previously untested. Also included in this patch series is a fix for a race condition discovered while testing request_firmware_into_buf. Mutex may not be correct final solution but demonstrates a fix to a race condition new test exposes.

[PATCH v14 00/18] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Shuah by removing two macros that were causing checkpatch errors. No API or major structual changes have been made since v13. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[1]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[2]. Additionally for convenience, I have applied these patches to a branch[3]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/v5.3/v14 branch. ## Changes Since Last Version - Removed to macros which helped define expectation and assertion macros; these values are now just copied and pasted. Change was made to fix checkpatch error, as suggested by Shuah.

Regression in 5.3-rc1 and later

by Chris Clayton

Hi everyone, Firstly, apologies to anyone on the long cc list that turns out not to be particularly interested in the following, but you were all marked as cc'd in the commit message below. I've found a problem that isn't present in 5.2 series or 4.19 series kernels, and seems to have arrived in 5.3-rc1. The problem is that if I suspend (to ram) my laptop, on resume 14 minutes or more after suspending, I have no networking functionality. If I resume the laptop after 13 minutes or less, networking works fine. I haven't tried to get finer grained timings between 13 and 14 minutes, but can do if it would help. ifconfig shows that wlan0 is still up and still has its assigned ip address but, for instance, a ping of any other device on my network, fails as does pinging, say, kernel.org. I've tried "downing" the network with (/sbin/ifdown) and unloading the iwlmvm module and then reloading the module and "upping" (/sbin/ifup) the network, but my network is still unusable. I should add that the problem also manifests if I hibernate the laptop, although my testing of this has been minimal. I can do more if required. As I say, the problem first appears in 5.3-rc1, so I've bisected between 5.2.0 and 5.3-rc1 and that concluded with: [chris:~/kernel/linux]$ git bisect good 7ac8707479886c75f353bfb6a8273f423cfccb23 is the first bad commit commit 7ac8707479886c75f353bfb6a8273f423cfccb23 Author: Vincenzo Frascino <vincenzo.frascino(a)arm.com> Date: Fri Jun 21 10:52:49 2019 +0100 x86/vdso: Switch to generic vDSO implementation The x86 vDSO library requires some adaptations to take advantage of the newly introduced generic vDSO library.

As expected, the kernel exhibited the problem I've described. However, a kernel built at the immediately preceding (parent?) commit (bfe801ebe84f42b4666d3f0adde90f504d56e35b) has a working network after a (>= 14minute) suspend/resume cycle. As the module name implies, I'm using wireless networking. The hardware is detected as "Intel(R) Wireless-AC 9260 160MHz, REV=0x324" by iwlwifi. I'm more than happy to provide additional diagnostics (but may need a little hand-holding) and to apply diagnostic or fix patches, but please cc me on any reply as I'm not subscribed to any of the kernel-related mailing lists.

[PATCH v2 0/2] firmware: selftest for request_firmware_into_buf

by Scott Branden

This patch series adds kernel selftest of request_firmware_into_buf. The API was added to the kernel previously untested. Changes from v1: - Dropped demonstration patch for a race condition discovered while testing request_firmare_into_buf. The new test exposes a kernel opps with the firmware fallback mechanism that may be fixed separate from these tests. - minor whitespace formatting in patch - added Ack's - added "s" in commit message (changed selftest: to selftests:) Scott Branden (2): test_firmware: add support for request_firmware_into_buf selftests: firmware: Add request_firmware_into_buf tests lib/test_firmware.c | 50 +++++++++++++++- .../selftests/firmware/fw_filesystem.sh | 57 ++++++++++++++++++- tools/testing/selftests/firmware/fw_lib.sh | 11 ++++ 3 files changed, 114 insertions(+), 4 deletions(-) -- 2.17.1

[PATCH v13 00/18] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Stephen and Bjorn Helgaas. Most changes are pretty minor stuff that doesn't affect the API in anyway. One significant change, however, is that I added support for freeing kunit_resource managed resources before the test case is finished via kunit_resource_destroy(). Additionally, Bjorn pointed out that I broke KUnit on certain configurations (like the default one for x86, whoops). Based on Stephen's feedback on the previous change, I think we are pretty close. I am not expecting any significant changes from here on out. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[1]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[2]. Additionally for convenience, I have applied these patches to a branch[3]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/v5.3/v13 branch. ## Changes Since Last Version - Added support for freeing kunit_resources (KUnit managed resources) via kunit_resource_destroy() as suggested by Stephen. - Promoted WARN() after __noreturn function to BUG() in "[PATCH v13 09/18] kunit: test: add support for test abort" as suggested by Stephen. - Dropped concept of death test since I am not actually using it yet as pointed out by Stephen. - Replaced usage of warn_slowpath_fmt with WARN in kunit_do_assertion since warn_slowpath_fmt is not available on some build configurations, as pointed out by Bjorn. - Lots of other minor changes suggested by Stephen.

[PATCH] selftests: use "$(MAKE)" instead of "make"

by Ilya Leoshkevich

When doing "make kselftest TARGETS=bpf -j12", bpf progs end up being compiled sequentially and thus slowly. The reason is that parent make (tools/testing/selftests/Makefile) does not share its jobserver with child make (tools/testing/selftests/bpf/Makefile), therefore the latter runs with -j1. Change all instances of "make" to "$(MAKE)", so that the whole make hierarchy runs using a single jobserver. Signed-off-by: Ilya Leoshkevich <iii(a)linux.ibm.com> --- I tested this with: make kselftest make -C tools/testing/selftests make -C tools/testing/selftests/bpf Unfortunately, in my setup a lot of tests fail for a number of reasons.

[RFC PATCH v2 0/5] hugetlb_cgroup: Add hugetlb_cgroup reservation limits

by Mina Almasry

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. - 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, with tests to verify functionality and show the usage. Alternatives considered: 1. A new cgroup, instead of only a new page_counter attached to the existing hugetlb_cgroup. Adding a new cgroup seemed like a lot of code duplication with hugetlb_cgroup. Keeping hugetlb related page counters under hugetlb_cgroup seemed cleaner as well. 2. Instead of adding a new counter, we considered adding a sysctl that modifies the behavior of hugetlb.xMB.[limit|usage]_in_bytes, to do accounting at reservation time rather than fault time. Adding a new page_counter seems better as userspace could, if it wants, choose to enforce different cgroups differently: one via limit_in_bytes, and another via reservation_limit_in_bytes. This could be very useful if you're transitioning how hugetlb memory is partitioned on your system one cgroup at a time, for example. Also, someone may find usage for both limit_in_bytes and reservation_limit_in_bytes concurrently, and this approach gives them the option to do so. Caveats: 1. This support is implemented for cgroups-v1. I have not tried hugetlb_cgroups with cgroups v2, and AFAICT it's not supported yet. This is largely because we use cgroups-v1 for now. If required, I can add hugetlb_cgroup support to cgroups v2 in this patch or a follow up. 2. Most complicated bit of this patch I believe is: where to store the pointer to the hugetlb_cgroup to uncharge at unreservation time? Normally the cgroup pointers hang off the struct page. But, with hugetlb_cgroup reservations, one task can reserve a specific page and another task may fault it in (I believe), so storing the pointer in struct page is not appropriate. Proposed approach here is to store the pointer in the resv_map. See patch for details.

From: Ido Schimmel <idosch(a)mellanox.com> [ Upstream commit 1be79d89b7ae96e004911bd228ce8c2b5cc6415f ] The TC filters used in the test do not work with veth devices because the outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw netdevs since the hardware always looks at "The first Ethertype that does not point to either: VLAN, CNTAG or configurable Ethertype". Fix this by matching on the VLAN ID instead, but on the ingress side. The reason why this is not performed at egress is explained in the commit cited below.
