[PATCH] selftests: watchdog: Add optional file argument

by George G. Davis

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. Signed-off-by: George G.

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. Reported-by: Randy Dunlap <rdunlap(a)infradead.org> Link: https://lore.kernel.org/linux-kselftest/0352fae9-564f-4a97-715a-fabe016259d… Cc: Stephen Rothwell <sfr(a)canb.auug.org.au> Signed-off-by: Brendan Higgins <brendanhiggins(a)google.com> --- include/kunit/test.h | 7 +++++++ kunit/test.c | 41 ++++++++++++++++++++++++----------------- 2 files changed, 31 insertions(+), 17 deletions(-) diff --git a/include/kunit/test.h b/include/kunit/test.h index 8b7eb03d4971..339af5f95c4a 100644 --- a/include/kunit/test.h +++ b/include/kunit/test.h @@ -339,9 +339,16 @@ static inline void *kunit_kzalloc(struct kunit *test, size_t size, gfp_t gfp) void kunit_cleanup(struct kunit *test); +#ifdef CONFIG_PRINTK void __printf(3, 4) kunit_printk(const char *level, const struct kunit *test, const char *fmt, ...); +#else +static inline void __printf(3, 4) kunit_printk(const char *level, + const struct kunit *test, + const char *fmt, ...) +{} +#endif /** * kunit_info() - Prints an INFO level message associated with @test. diff --git a/kunit/test.c b/kunit/test.c index b2ca9b94c353..0aa1caf07a6b 100644 --- a/kunit/test.c +++ b/kunit/test.c @@ -16,6 +16,7 @@ static void kunit_set_failure(struct kunit *test) WRITE_ONCE(test->success, false); } +#ifdef CONFIG_PRINTK static int kunit_vprintk_emit(int level, const char *fmt, va_list args) { return vprintk_emit(0, level, NULL, 0, fmt, args); @@ -40,6 +41,29 @@ static void kunit_vprintk(const struct kunit *test, kunit_printk_emit(level[1] - '0', "\t# %s: %pV", test->name, vaf); } +void kunit_printk(const char *level, + const struct kunit *test, + const char *fmt, ...) +{ + struct va_format vaf; + va_list args; + + va_start(args, fmt); + + vaf.fmt = fmt; + vaf.va = &args; + + kunit_vprintk(test, level, &vaf); + + va_end(args); +} +#else /* CONFIG_PRINTK */ +static inline int kunit_printk_emit(int level, const char *fmt, ...) +{ + return 0; +} +#endif /* CONFIG_PRINTK */ + static void kunit_print_tap_version(void) { static bool kunit_has_printed_tap_version; @@ -504,20 +528,3 @@ void kunit_cleanup(struct kunit *test) kunit_resource_free(test, resource); } } - -void kunit_printk(const char *level, - const struct kunit *test, - const char *fmt, ...) -{ - struct va_format vaf; - va_list args; - - va_start(args, fmt); - - vaf.fmt = fmt; - vaf.va = &args; - - kunit_vprintk(test, level, &vaf); - - va_end(args); -} -- 2.23.0.187.g17f5b7556c-goog

Hi Chris, When running the new dmabuf-selftests on two different systems, I get: dma-buf: Running sanitycheck dma-buf: Running dma_fence sizeof(dma_fence)=48 dma-buf: Running dma_fence/sanitycheck dma-buf: Running dma_fence/test_signaling dma-buf: Running dma_fence/test_add_callback dma-buf: Running dma_fence/test_late_add_callback dma-buf: Running dma_fence/test_rm_callback dma-buf: Running dma_fence/test_late_rm_callback dma-buf: Running dma_fence/test_status dma-buf: Running dma_fence/test_error dma-buf: Running dma_fence/test_wait dma-buf: Running dma_fence/test_wait_timeout dma-buf: Running dma_fence/test_stub dma-buf: Running dma_fence/race_signal_callback thread_signal_callback[0] completed 28855 passes, 3929 misses thread_signal_callback[1] completed 28846 passes, 3918 misses thread_signal_callback[0] completed 37179 passes, 37179 misses thread_signal_callback[1] completed 37184 passes, 37183 misses and dma-buf: Running sanitycheck dma-buf: Running dma_fence sizeof(dma_fence)=64 dma-buf: Running dma_fence/sanitycheck dma-buf: Running dma_fence/test_signaling dma-buf: Running dma_fence/test_add_callback dma-buf: Running dma_fence/test_late_add_callback dma-buf: Running dma_fence/test_rm_callback dma-buf: Running dma_fence/test_late_rm_callback dma-buf: Running dma_fence/test_status dma-buf: Running dma_fence/test_error dma-buf: Running dma_fence/test_wait dma-buf: Running dma_fence/test_wait_timeout dma-buf: Running dma_fence/test_stub dma-buf: Running dma_fence/race_signal_callback thread_signal_callback[0] completed 3423 passes, 2148 misses thread_signal_callback[1] completed 2360 passes, 9 misses thread_signal_callback[0] completed 4028 passes, 4028 misses thread_signal_callback[1] completed 8080 passes, 8079 misses Unfortunately it is not clear to me if this is good or bad? Perhaps the test output can be improved, e.g. with a clear PASS/FAIL output? Thanks!

[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.

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.

[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.

[PATCH] selftests: livepatch: add missing fragments to config

by Anders Roxell

When generating config with 'make defconfig kselftest-merge' fragment CONFIG_TEST_LIVEPATCH=m isn't set. Rework to enable CONFIG_LIVEPATCH and CONFIG_DYNAMIC_DEBUG as well.

[PATCH AUTOSEL 4.19 12/68] selftests: forwarding: gre_multipath: Fix flower filters

by Sasha Levin

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.

[PATCH v12 00/18] kunit: introduce KUnit, the Linux kernel unit testing framework

## TL;DR This revision removes dependence on kunit_stream in favor of kunit_assert, as suggested by Stephen Boyd. kunit_assert provides a more structured interface for constructing messages and allows most required data to be stored on the stack for most expectations until it is determined that a failure message must be produced. As a part of introducing kunit_assert, expectations (KUNIT_EXPECT_*) and assertions (KUNIT_ASSERT_*) have been substantially refactored. Nevertheless, behavior should be the same. As this revision, adds a new patch, it, [PATCH v12 04/18], needs to be reviewed. All other patches have appropriate reviews and acks. I also rebased the patchset on v5.3-rc3. ## 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/v12 branch. ## Changes Since Last Version - Dropped patch "[PATCH v11 04/18] kunit: test: add kunit_stream a std::stream like logger" and replaced it with "[PATCH v12 04/18] kunit: test: add assertion printing library", which provides a totally new mechanism for constructing expectation/assertion failure messages. - Substantially refactored expectations and assertions definitions in [PATCH 05/18] and [PATCH 11/18] respectively. - Rebased patchset on v5.3-rc3. - Fixed a minor documentation bug.

[PATCH v9 00/18] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This new patch set only contains a very minor change to address a sparse warning in the PROC SYSCTL KUnit test. Otherwise this patchset is identical to the previous. As I mentioned in the previous patchset, all patches now have acks and reviews. ## 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.

The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/v5.2/v9 branch. ## Changes Since Last Version Like I said in the TL;DR, there is only one minor change since the previous revision. That change only affects patch 17/18; it addresses a sparse warning in the PROC SYSCTL unit test. Thanks to Masahiro for applying previous patches to a branch in his kbuild tree and running sparse and other static analysis tools against my patches.
