[PATCH net 0/2] selftests: pmtu.sh: Fix cleanup of processes launched in subshell.

by Guillaume Nault

Depending on the options used, pmtu.sh may launch tcpdump and nettest processes in the background. However it fails to clean them up after the tests complete. Patch 1 allows the cleanup() function to read the list of PIDs launched by the tests. Patch 2 fixes the way the nettest PIDs are retrieved. v2: * Use tcpdump's immediate mode to capture packets even in short lived tests. * Add patch 2 to fix the nettest_pids list. Guillaume Nault (2): selftests: pmtu.sh: Kill tcpdump processes launched by subshell. selftests: pmtu.sh: Kill nettest processes launched in subshell. tools/testing/selftests/net/pmtu.sh | 21 +++++++++++++++++---- 1 file changed, 17 insertions(+), 4 deletions(-) -- 2.21.3

[PATCH v1 0/3] kselftest/arm64: Test ptrace writing via FPSIMD and reading via SVE

by Mark Brown

This series has a couple of minor fixes and cleanups for sve-ptrace plus the addition of a new test which validates that we can write using the FPSIMD regset and then read matching data back using the SVE regset - previously we only validated writing SVE and reading FPSIMD data. Mark Brown (3): kselftest/arm64: Fix comment for ptrace_sve_get_fpsimd_data() kselftest/arm64: Remove assumption that tasks start FPSIMD only kselftest/arm64: Validate setting via FPSIMD and read via SVE regsets tools/testing/selftests/arm64/fp/sve-ptrace.c | 164 +++++++++++++++--- 1 file changed, 139 insertions(+), 25 deletions(-) base-commit: dfd42facf1e4ada021b939b4e19c935dcdd55566 -- 2.30.2

[PATCH 0/3] kunit: fix a UAF bug and do some optimization

by Peng Liu

This series is to fix UAF when running kfence test case test_gfpzero, which is time costly. This UAF bug can be easily triggered by setting CONFIG_KFENCE_DYNAMIC_OBJECTS = 65535. Furthermore, some optimization for kunit tests has been done.
