[PATCH] selftests/clone3: fix number of tests in ksft_set_plan

by Tobias Klauser

Commit 515bddf0ec41 ("selftests/clone3: test clone3 with CLONE_NEWTIME") added an additional test, so the number passed to ksft_set_plan needs to be bumped accordingly. Also use ksft_finish to print results and exit. This will catch future mismatches between ksft_set_plan and the number of tests being run.

Re: [Syzkaller & bisect] There is WARNING: refcount bug in sock_map_free in v6.3-rc1

by Pengfei Xu

++ GPIO and kself-test mailing list. Hi kernel experts, It's a soft remind. My colleague Lai Yi found that similar "refcount_t: underflow; use-after-free" issue still existed in v6.3-rc5 kernel on x86 platforms. We could reproduce issue from kself-test: gpio-mockup.sh easily: kernel/tools/testing/selftests/gpio/gpio-mockup.sh: " [ 5781.338917] -----------[ cut here ]----------- [ 5781.344192] refcount_t: underflow; use-after-free.

[PATCH bpf-next v2 2/2] selftests: xsk: Add test UNALIGNED_INV_DESC_4K1_FRAME_SIZE

by Kal Conley

Add unaligned descriptor test for frame size of 4001. Using an odd frame size ensures that the end of the UMEM is not near a page boundary. This allows testing descriptors that staddle the end of the UMEM but not a page. This test used to fail without the previous commit ("xsk: Add check for unaligned descriptors that overrun UMEM").
