[PATCH v2 net 0/2] openvswitch: syzbot splat fix and introduce selftest

by Aaron Conole

Syzbot recently caught a splat when dropping features from openvswitch datapaths that are in-use. The WARN() call is definitely too large a hammer for the situation, so change to pr_warn. Second patch in the series introduces a new selftest suite which can help show that an issue is fixed. This change might be more suited to net-next tree, so it has been separated out as an additional patch and can be either applied to either tree based on preference.

[PATCH v7 0/3] Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros

by Maíra Canal

Currently, in order to compare memory blocks in KUnit, the KUNIT_EXPECT_EQ or KUNIT_EXPECT_FALSE macros are used in conjunction with the memcmp function, such as: KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); Although this usage produces correct results for the test cases, if the expectation fails the error message is not very helpful, indicating only the return of the memcmp function. Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v7 has some formatting changes on the first patch and it was rebased on top of the mainline (due to 7089003304c6). The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.

[PATCH] selftests: vm: use 1 MB hugepage size for s390

hugepage-vmemmap test fails for s390 because it assumes a hugepagesize of 2 MB, while we have 1 MB on s390. This results in iterating over two hugepages. If they are consecutive in memory, check_page_flags() will stumble over the additional head page. Otherwise, it will stumble over non-huge pageflags, after crossing the first 1 MB hugepage. Fix this by using 1 MB MAP_LENGTH for s390.

[PATCH v2 1/3] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs. Signed-off-by: David Gow <davidgow(a)google.com> --- This should be a no-op (other than a possible performance improvement) functionality-wise, and lays the groundwork for a more optimised static stub implementation. The remaining patches in the series add a kunit_get_current_test() function which is a more friendly and performant wrapper around current->kunit_test, and use this in the slub test. They also improve the documentation a bit. If there are no objections, we'll take the whole series via the KUnit tree.

[PATCH] Documentation: kunit: Remove redundant 'tips.rst' page

by David Gow

The contents of 'tips.rst' was included in 'usage.rst' way back in commit 953574390634 ("Documentation: KUnit: Rework writing page to focus on writing tests"), but the tips page remained behind as well. Therefore, delete 'tips.rst' While I regret breaking any links to 'tips' which might exist externally, it's confusing to have two subtly different versions of the same content around.

[PATCH 0/4] mm/damon/reclaim,lru_sort: enable/disable synchronously

by SeongJae Park

Writing a value to DAMON_RECLAIM and DAMON_LRU_SORT's 'enabled' parameters turns on or off DAMON in an ansychronous way. This means the parameter cannot be used to read the current status of them. 'kdamond_pid' parameter should be used instead for the purpose. The documentation is easy to be read as it works in a synchronous way, so it is a little bit confusing. It also makes the user space tooling dirty. There's no real reason to have the asynchronous behavior, though. Simply make the parameter works synchronously, rather than updating the document. The first and second patches changes the behavior of the 'enabled' parameter for DAMON_RECLAIM and adds a selftest for the changed behavior, respectively. Following two patches make the same changes for DAMON_LRU_SORT. SeongJae Park (4): mm/damon/reclaim: enable and disable synchronously selftests/damon: add tests for DAMON_RECLAIM's enabled parameter mm/damon/lru_sort: enable and disable synchronously selftests/damon: add tests for DAMON_LRU_SORT's enabled parameter mm/damon/lru_sort.c | 51 ++++++++++------------ mm/damon/reclaim.c | 53 ++++++++++------------- tools/testing/selftests/damon/Makefile | 1 + tools/testing/selftests/damon/lru_sort.sh | 41 ++++++++++++++++++ tools/testing/selftests/damon/reclaim.sh | 42 ++++++++++++++++++ 5 files changed, 129 insertions(+), 59 deletions(-) create mode 100755 tools/testing/selftests/damon/lru_sort.sh create mode 100755 tools/testing/selftests/damon/reclaim.sh -- 2.25.1

[PATCH v4 00/23] SMM emulation and interrupt shadow fixes

by Maxim Levitsky

This patch series is a result of long debug work to find out why sometimes guests with win11 secure boot were failing during boot. During writing a unit test I found another bug, turns out that on rsm emulation, if the rsm instruction was done in real or 32 bit mode, KVM would truncate the restored RIP to 32 bit. I also refactored the way we write SMRAM so it is easier now to understand what is going on. The main bug in this series which I fixed is that we allowed #SMI to happen during the STI interrupt shadow, and we did nothing to both reset it on #SMI handler entry and restore it on RSM. V4: - rebased on top of patch series from Paolo which allows smm support to be disabled by Kconfig option. - addressed review feedback. I included these patches in the series for reference.

[PATCH net 0/2] openvswitch: syzbot splat fix and introduce selftest

by Aaron Conole

Syzbot recently caught a splat when dropping features from openvswitch datapaths that are in-use. The WARN() call is definitely too large a hammer for the situation, so change to pr_warn. Second patch in the series introduces a new selftest suite which can help show that an issue is fixed. This change might be more suited to net-next tree, so it has been separated out as an additional patch and can be either applied to either tree based on preference.

[PATCH v1 0/7] selftests/vm: test COW handling of anonymous memory

by David Hildenbrand

On top of mm-stable. This is my current set of tests for testing COW handling of anonymous memory, especially when interacting with GUP. I developed these tests while working on PageAnonExclusive and managed to clean them up just now. On current upstream Linux, all tests pass except the hugetlb tests that rely on vmsplice -- these tests should pass as soon as vmsplice properly uses FOLL_PIN instead of FOLL_GET. I'm working on additional tests for COW handling in private mappings, focusing on long-term R/O pinning e.g., of the shared zeropage, pagecache pages and KSM pages. These tests, however, will go into a different file. So this is everything I have regarding tests for anonymous memory.

[PATCH v15 0/3]] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in Documentation/x86/tdx.rst (added by patch 2/3). Following are the details of the patch set: Patch 1/3 -> Preparatory patch for adding attestation support. Patch 2/3 -> Adds user interface driver to support attestation. Patch 3/3 -> Adds selftest support for TDREPORT feature. Commit log history is maintained in the individual patches.

[PATCH v8 net-next 00/12] Extend locked port feature with FDB locked flag (MAC-Auth/MAB)

by Hans J. Schultz

This patch set extends the locked port feature for devices that are behind a locked port, but do not have the ability to authorize themselves as a supplicant using IEEE 802.1X. Such devices can be printers, meters or anything related to fixed installations. Instead of 802.1X authorization, devices can get access based on their MAC addresses being whitelisted. For an authorization daemon to detect that a device is trying to get access through a locked port, the bridge will add the MAC address of the device to the FDB with a locked flag to it. Thus the authorization daemon can catch the FDB add event and check if the MAC address is in the whitelist and if so replace the FDB entry without the locked flag enabled, and thus open the port for the device. This feature is known as MAC-Auth or MAC Authentication Bypass (MAB) in Cisco terminology, where the full MAB concept involves additional Cisco infrastructure for authorization. There is no real authentication process, as the MAC address of the device is the only input the authorization daemon, in the general case, has to base the decision if to unlock the port or not. With this patch set, an implementation of the offloaded case is supplied for the mv88e6xxx driver. When a packet ingresses on a locked port, an ATU miss violation event will occur. When handling such ATU miss violation interrupts, the MAC address of the device is added to the FDB with a zero destination port vector (DPV) and the MAC address is communicated through the switchdev layer to the bridge, so that a FDB entry with the locked flag enabled can be added. Log: v3: Added timers and lists in the driver (mv88e6xxx) to keep track of and remove locked entries. v4: Leave out enforcing a limit to the number of locked entries in the bridge. Removed the timers in the driver and use the worker only. Add locked FDB flag to all drivers using port_fdb_add() from the dsa api and let all drivers ignore entries with this flag set. Change how to get the ageing timeout of locked entries. See global1_atu.c and switchdev.c. Use struct mv88e6xxx_port for locked entries variables instead of struct dsa_port. v5: Added 'mab' flag to enable MAB/MacAuth feature, in a similar way to the locked feature flag. In these implementations for the mv88e6xxx, the switchport must be configured with learning on. To tell userspace about the behavior of the locked entries in the driver, a 'blackhole' FDB flag has been added, which locked FDB entries coming from the driver gets. Also the 'sticky' flag comes with those locked entries, as the drivers locked entries cannot roam. Fixed issues with taking mutex locks, and added a function to read the fid, that supports all versions of the chipset family. v6: Added blackhole FDB flag instead of using sticky flag, as the blackhole flag corresponds to the behaviour of the zero-DPV locked entries in the driver. Userspace can add blackhole FDB entries with: # bridge fdb add MAC dev br0 blackhole Added FDB flags towards driver in DSA layer as u16. v7: Remove locked port and mab flags from DSA flags inherit list as it messes with the learning setting and those flags are not naturally meant for enheriting, but should be set explicitly. Fix blackhole implementation, selftests a.o small fixes. v8: Improvements to error messages with user space added blackhole entries and improvements to the selftests. Hans J.

[PATCH 1/2] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs.

[PATCH v1 0/7] mm/ksm: break_ksm() cleanups and fixes

by David Hildenbrand

This series cleans up and fixes break_ksm(). In summary, we no longer use fake write faults to break COW but instead FAULT_FLAG_UNSHARE. Further, we move away from using follow_page() [that we can hopefully remove completely at one point] and use new walk_page_range_vma() instead. Fortunately, we can get rid of VM_FAULT_WRITE and FOLL_MIGRATION in common code now. Add a selftest to measure MADV_UNMERGEABLE performance. In my setup (AMD Ryzen 9 3900X), running the KSM selftest to test unmerge performance on 2 GiB (taskset 0x8 ./ksm_tests -D -s 2048), this results in a performance degradation of ~8% -- 9% (old: ~5250 MiB/s, new: ~4800 MiB/s). I don't think we particularly care for now, but it's good to be aware of the implication.

tools/nolibc: fix missing strlen() definition and infinite loop with gcc-12

by Willy Tarreau

When built at -Os, gcc-12 recognizes an strlen() pattern in nolibc_strlen() and replaces it with a jump to strlen(), which is not defined as a symbol and breaks compilation. Worse, when the function is called strlen(), the function is simply replaced with a jump to itself, hence becomes an infinite loop. One way to avoid this is to always set -ffreestanding, but the calling code doesn't know this and there's no way (either via attributes or pragmas) to globally enable it from include files, effectively leaving a painful situation for the caller. It turns out that -fno-tree-loop-distribute-patterns disables replacement of strlen-like loops with calls to strlen and that this option is accepted in the optimize() function attribute. Thus at least it allows us to make sure our local definition is not replaced with a self jump. The function only needs to be renamed back to strlen() so that the symbol exists, which implies that nolibc_strlen() which is used on variable strings has to be declared as a macro that points back to it before the strlen() macro is redifined. It was verified to produce valid code with gcc 3.4 to 12.1 at different optimization levels, and both with constant and variable strings.

[PATCH v1] selftests: Use optional USERCFLAGS and USERLDFLAGS

by Mickaël Salaün

This change enables to extend CFLAGS and LDFLAGS from command line, e.g. to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static USERCFLAGS and USERLDFLAGS are documented in Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst This should be backported (down to 5.10) to improve previous kernel versions testing as well.

[PATCH] kasan: Enable KUnit integration whenever CONFIG_KUNIT is enabled

by David Gow

Enable the KASAN/KUnit integration even when the KASAN tests are disabled, as it's useful for testing other things under KASAN. Essentially, this reverts commit 49d9977ac909 ("kasan: check CONFIG_KASAN_KUNIT_TEST instead of CONFIG_KUNIT"). To mitigate the performance impact slightly, add a likely() to the check for a currently running test. There's more we can do for performance if/when it becomes more of a problem, such as only enabling the "expect a KASAN failure" support wif the KASAN tests are enabled, or putting the whole thing behind a "kunit tests are running" static branch (which I do plan to do eventually). Fixes: 49d9977ac909 ("kasan: check CONFIG_KASAN_KUNIT_TEST instead of CONFIG_KUNIT") Signed-off-by: David Gow <davidgow(a)google.com> --- Basically, hiding the KASAN/KUnit integration broke being able to just pass --kconfig_add CONFIG_KASAN=y to kunit_tool to enable KASAN integration. We didn't notice this, because usually CONFIG_KUNIT_ALL_TESTS is enabled, which in turn enables CONFIG_KASAN_KUNIT_TEST. However, using a separate .kunitconfig might result in failures being missed. Take, for example: ./tools/testing/kunit/kunit.py run --kconfig_add CONFIG_KASAN=y \ --kunitconfig drivers/gpu/drm/tests This should run the drm tests with KASAN enabled, but even if there's a KASAN failure (such as the one fixed by [1]), kunit_tool will report success.

[PATCH v1] selftests/landlock: Build without static libraries

by Mickaël Salaün

The only (forced) static test binary doesn't depend on libcap. Because using -lcap on systems that don't have such static library would fail (e.g. on Arch Linux), let's be more specific and require only dynamic libcap linking.

Changes on this v11: o Fixed a minor typo on patch #2 as noted by Kees Cook o Added Reviewed-by tags by Kees Cook Changes on this v10: o embraced paragraph from Thomas Gleixner which helps explain why the OR operator in the SPDX license name o dropped the GPL-2.0 and GPL-2.0+ tags as suggested by Thomas Gleixner as these are outdated (still valid) in the SPDX spec o trimmed the Cc list to remove the test_sysfs / block layer / fs folks as the test_sysfs stuff is now dropped from consideration in this series Prior to this the series was at v9 but it also had the test_sysfs and its changes, its history can be found here: https://lore.kernel.org/all/20211029184500.2821444-1-mcgrof@kernel.org/ Luis Chamberlain (2): LICENSES: Add the copyleft-next-0.3.1 license testing: use the copyleft-next-0.3.1 SPDX tag LICENSES/dual/copyleft-next-0.3.1 | 236 +++++++++++++++++++++++ lib/test_kmod.c | 12 +- lib/test_sysctl.c | 12 +- tools/testing/selftests/kmod/kmod.sh | 13 +- tools/testing/selftests/sysctl/sysctl.sh | 12 +- 5 files changed, 240 insertions(+), 45 deletions(-) create mode 100644 LICENSES/dual/copyleft-next-0.3.1 -- 2.35.1

[PATCH v3 0/4] Implement IOCTL to get and clear soft dirty PTE

by Muhammad Usama Anjum

Hello, This patch series implements a new ioctl on the pagemap proc fs file to get, clear and perform both get and clear at the same time atomically on the specified range of the memory. Soft-dirty PTE bit of the memory pages can be viewed by using pagemap procfs file. The soft-dirty PTE bit for the whole memory range of the process can be cleared by writing to the clear_refs file. This series adds features that weren't present earlier. - There is no atomic get soft-dirty PTE bit status and clear operation present. - The soft-dirty PTE bit of only a part of memory cannot be cleared. Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The proc fs interface is enough for that as I think the process is frozen. We have the use case where we need to track the soft-dirty PTE bit for the running processes. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. This syscall is used by games to keep track of dirty pages and keep processing only the dirty pages. This new ioctl can be used by the CRIU project and other applications which require soft-dirty PTE bit information. As in the current kernel there is no way to clear a part of memory (instead of clearing the Soft-Dirty bits for the entire process) and get+clear operation cannot be performed atomically, there are other methods to mimic this information entirely in userspace with poor performance: - The mprotect syscall and SIGSEGV handler for bookkeeping - The userfaultfd syscall with the handler for bookkeeping Some benchmarks can be seen [1]. This ioctl can be used by the CRIU project and other applications which require soft-dirty PTE bit information. The following operations are supported in this ioctl: - Get the pages that are soft-dirty. - Clear the pages which are soft-dirty. - The optional flag to ignore the VM_SOFTDIRTY and only track per page soft-dirty PTE bit There are two decisions which have been taken about how to get the output from the syscall. - Return offsets of the pages from the start in the vec - Stop execution when vec is filled with dirty pages These two arguments doesn't follow the mincore() philosophy where the output array corresponds to the address range in one to one fashion, hence the output buffer length isn't passed and only a flag is set if the page is present. This makes mincore() easy to use with less control. We are passing the size of the output array and putting return data consecutively which is offset of dirty pages from the start. The user can convert these offsets back into the dirty page addresses easily. Suppose, the user want to get first 10 dirty pages from a total memory of 100 pages. He'll allocate output buffer of size 10 and the ioctl will abort after finding the 10 pages. This behaviour is needed to support Windows' getWriteWatch(). The behaviour like mincore() can be achieved by passing output buffer of 100 size. This interface can be used for any desired behaviour.

[PATCH v6 0/3] Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros

by Maíra Canal

Currently, in order to compare memory blocks in KUnit, the KUNIT_EXPECT_EQ or KUNIT_EXPECT_FALSE macros are used in conjunction with the memcmp function, such as: KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); Although this usage produces correct results for the test cases, if the expectation fails the error message is not very helpful, indicating only the return of the memcmp function. Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v6 has some changes on the first patch, due to rebase on top of Linux 6.1, specially the renaming of KUNIT_ASSERTION macro to _KUNIT_FAILED (97d453bc4007d4ac148c2ba89904026612b91ec9). Moreover, the DRM KUnit tests were mainlined in 6.1. The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.
