233e667e - selftests/rseq: Uplift rseq selftests for compatibility with glibc-2.35

Mon, 24 Jan 2022 17:12:45 +0000

selftests/rseq: Uplift rseq selftests for compatibility with glibc-2.35glibc-2.35 (upcoming release date 2022-02-01) exposes the rseq per-threaddata in the TCB, accessible at an offset from the thread pointer, ratherthan through an actual Thread-Local Storage (TLS) variable, as theLinux kernel selftests initially expected.The __rseq_abi TLS and glibc-2.35's ABI for per-thread data cannotactively coexist in a process, because the kernel supports only a singlerseq registration per thread.Here is the scheme introduced to ensure selftests can work both with anolder glibc and with glibc-2.35+:- librseq exposes its own "rseq_offset, rseq_size, rseq_flags" ABI.- librseq queries for glibc rseq ABI (__rseq_offset, __rseq_size, __rseq_flags) using dlsym() in a librseq library constructor. If those are found, copy their values into rseq_offset, rseq_size, and rseq_flags.- Else, if those glibc symbols are not found, handle rseq registration from librseq and use its own IE-model TLS to implement the rseq ABI per-thread storage.Signed-off-by: Mathieu Desnoyers Signed-off-by: Peter Zijlstra (Intel) Link: https://lkml.kernel.org/r/20220124171253.22072-8-mathieu.desnoyers@efficios.com List of files: /linux-6.15/tools/testing/selftests/rseq/Makefile

b9167c80 - selftests: Install settings files to fix TIMEOUT failures

Thu, 20 Feb 2020 04:42:41 +0000

selftests: Install settings files to fix TIMEOUT failuresCommit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 secondtimeout per test") added a 45 second timeout for tests, and also addeda way for tests to customise the timeout via a settings file.For example the ftrace tests take multiple minutes to run, so theywere given longer in commit b43e78f65b1d ("tracing/selftests: Turn offtimeout setting").This works when the tests are run from the source tree. However if thetests are installed with "make -C tools/testing/selftests install",the settings files are not copied into the install directory. When thetests are then run from the install directory the longer timeouts arenot applied and the tests timeout incorrectly.So add the settings files to TEST_FILES of the appropriate Makefilesto cause the settings files to be installed using the existing installlogic.Fixes: 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test")Signed-off-by: Michael Ellerman Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/rseq/Makefile
