2024-12-20stddef: make __struct_group() UAPI C++-friendlyAlexander Lobakin
For the most part of the C++ history, it couldn't have type declarations inside anonymous unions for different reasons. At the same time, __struct_group() relies on the latters, so when the @TAG argument is not empty, C++ code doesn't want to build (even under `extern "C"`): ../linux/include/uapi/linux/pkt_cls.h:25:24: error: 'struct tc_u32_sel::<unnamed union>::tc_u32_sel_hdr,' invalid; an anonymous union may only have public non-static data members [-fpermissive] The safest way to fix this without trying to switch standards (which is impossible in UAPI anyway) etc., is to disable tag declaration for that language. This won't break anything since for now it's not buildable at all. Use a separate definition for __struct_group() when __cplusplus is defined to mitigate the error, including the version from tools/.

2024-12-20selftests/alsa: Fix circular dependency involving global-timerLi Zhijian
The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular dependency on the global-timer target due to its inclusion in $(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency warning during the build process. To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change ensures that libatest.so is built before any other targets that require it, without creating a circular dependency. This fix addresses the following warning: make[4]: Entering directory 'tools/testing/selftests/alsa' make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped. make[4]: Nothing to be done for 'all'. make[4]: Leaving directory 'tools/testing/selftests/alsa' Cc: Mark Brown <broonie@kernel.org> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Link: https://patch.msgid.link/20241218025931.914164-1-lizhijian@fujitsu.com Signed-off-by: Takashi Iwai <tiwai@suse.de>

2024-12-18selftests: openvswitch: fix tcpdump executionAdrian Moreno
Fix the way tcpdump is executed by: - Using the right variable for the namespace. Currently the use of the empty "ns" makes the command fail. - Waiting until it starts to capture to ensure the interesting traffic is caught on slow systems. - Using line-buffered output to ensure logs are available when the test is paused with "-p". Otherwise the last chunk of data might only be written when tcpdump is killed.

2024-12-18selftests/memfd: run sysctl tests when PID namespace support is enabledIsaac J. Manjarres
The sysctl tests for vm.memfd_noexec rely on the kernel to support PID namespaces (i.e. the kernel is built with CONFIG_PID_NS=y). If the kernel the test runs on does not support PID namespaces, the first sysctl test will fail when attempting to spawn a new thread in a new PID namespace, abort the test, preventing the remaining tests from being run. This is not desirable, as not all kernels need PID namespaces, but can still use the other features provided by memfd. Therefore, only run the sysctl tests if the kernel supports PID namespaces. Otherwise, skip those tests and emit an informative message to let the user know why the sysctl tests are not being run.

recv_size parameter allows constraining the buffer size for dumps. It's useful in testing kernel handling of dump continuation, IOW testing dumps which span multiple skbs. Let the tests set this parameter when initializing the YNL family. Keep the normal default, we don't want tests to unintentionally behave very differently than normal code.

2024-12-16selftests/exec: add a test for execveat()'s commTycho Andersen
In the previous patch we've updated AT_EMPTY_PATH execs to use the dentry filename. Test for this and just to be sure keeps working with symlinks, which was a concern in [1], I've added a test for that as well. The test itself is a bit ugly, because the existing check_execveat_fail() helpers use a hardcoded envp and argv, and we want to "pass" things via the environment to test various argument values, but it seemed cleaner than passing one in everywhere in all the existing tests. Output looks like: ok 51 Check success of execveat(6, 'home/tycho/packages/...yyyyyyyyyyyyyyyyyyyy', 0)... # Check execveat(AT_EMPTY_PATH)'s comm is execveat ok 52 Check success of execveat(9, '', 4096)... # Check execveat(AT_EMPTY_PATH)'s comm is execveat ok 53 Check success of execveat(11, '', 4096)... # Check execveat(AT_EMPTY_PATH)'s comm is execveat [ 25.579272] process 'execveat' launched '/dev/fd/9' with NULL argv: empty string added ok 54 Check success of execveat(9, '', 4096)...
