[PATCH] selftests/vDSO: fix ABI selftest on riscv

by Tobias Klauser

Only older versions of the RISC-V GCC toolchain define __riscv__. Check for __riscv as well, which is used by newer GCC toolchains. Also set VDSO_32BIT based on __riscv_xlen.

[PATCH] selftests/seccomp: Accept any valid fd in user_notification_addfd

by Seth Forshee

This test expects fds to have specific values, which works fine when the test is run standalone. However, the kselftest runner consumes a couple of extra fds for redirection when running tests, so the test fails when run via kselftest. Change the test to pass on any valid fd number.

[PATCH v2 0/2] kunit: fail tests on UBSAN errors

by Daniel Latypov

v1 by Uriel is here: [1]. Since it's been a while, I've dropped the Reviewed-By's. It depended on commit 83c4e7a0363b ("KUnit: KASAN Integration") which hadn't been merged yet, so that caused some kerfuffle with applying them previously and the series was reverted. This revives the series but makes the kunit_fail_current_test() function take a format string and logs the file and line number of the failing code, addressing Alan Maguire's comments on the previous version. As a result, the patch that makes UBSAN errors was tweaked slightly to include an error message.

Correct .gitignore in several places for kselftest outputs

by Erik Hollensbe

Sincerely hope I did this right; first time contributor, learning the patch workflow. I took the opportunity to fix two .gitignore files that were leaving stale worktree/index outputs after running `make kselftest` against recent mainline (76c057c84d286140c6c416c3b4ba832cd1d8984e). Thanks for your time!

[PATCH] selftests/core: fix close_range_test build after XFAIL removal

by Tobias Klauser

XFAIL was removed in commit 9847d24af95c ("selftests/harness: Refactor XFAIL into SKIP") and its use in close_range_test was already replaced by commit 1d44d0dd61b6 ("selftests: core: use SKIP instead of XFAIL in close_range_test.c"). However, commit 23afeaeff3d9 ("selftests: core: add tests for CLOSE_RANGE_CLOEXEC") introduced usage of XFAIL in TEST(close_range_cloexec). Use SKIP there as well.
