[PATCH AUTOSEL 6.1 08/25] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF

by Sasha Levin

From: Oliver Upton <oliver.upton(a)linux.dev> [ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ] Assert that accesses to a non-existent vgic-v2 CPU interface consistently fail across the various KVM device attr ioctls. This also serves as a regression test for a bug wherein KVM hits a NULL dereference when the CPUID specified in the ioctl is invalid. Note that there is no need to print the observed errno, as TEST_ASSERT() will take care of it.

[PATCH v3 00/68] Define _GNU_SOURCE for sources using

by Edward Liaw

Centralizes the definition of _GNU_SOURCE into KHDR_INCLUDES and removes redefinitions of _GNU_SOURCE from source code. 809216233555 ("selftests/harness: remove use of LINE_MAX") introduced asprintf into kselftest_harness.h, which is a GNU extension and needs _GNU_SOURCE to either be defined prior to including headers or with the -D_GNU_SOURCE flag passed to the compiler. v1: https://lore.kernel.org/linux-kselftest/20240430235057.1351993-1-edliaw@goo… v2: https://lore.kernel.org/linux-kselftest/20240507214254.2787305-1-edliaw@goo… - Add -D_GNU_SOURCE to KHDR_INCLUDES so that it is in a single location. - Remove #define _GNU_SOURCE from source code to resolve redefinition warnings. v3: - Rebase onto linux-next. - Split patches by directory. - Add -D_GNU_SOURCE directly to CFLAGS in lib.mk. - Delete additional _GNU_SOURCE definitions from source code in linux-next. - Delete additional -D_GNU_SOURCE flags from Makefiles.

[PATCH bpf-next] selftests/bpf: Free strdup memory in xdp_hw_metadata

by Geliang Tang

From: Geliang Tang <tanggeliang(a)kylinos.cn> The strdup() function returns a pointer to a new string which is a duplicate of the string "ifname". Memory for the new string is obtained with malloc(), and need to be freed with free(). This patch adds this missing "free(saved_hwtstamp_ifname)" in cleanup() to avoid a potential memory leak in xdp_hw_metadata.c.

[PATCH v1 bpf-next 00/17] Retire progs/test_sock_addr.c

by Jordan Rife

This patch series migrates remaining tests from bpf/test_sock_addr.c to prog_tests/sock_addr.c and progs/verifier_sock_addr.c in order to fully retire the old-style test program and expands test coverage to test previously untested scenarios related to sockaddr hooks. This is a continuation of the work started recently during the expansion of prog_tests/sock_addr.c. Link: https://lore.kernel.org/bpf/20240429214529.2644801-1-jrife@google.com/T/#u ======= Patches ======= * Patch 1 moves tests that check valid return values for recvmsg hooks into progs/verifier_sock_addr.c, a new addition to the verifier test suite. * Patches 2-5 lay the groundwork for test migration, enabling prog_tests/sock_addr.c to handle more test dimensions. * Patches 6-11 move existing tests to prog_tests/sock_addr.c. * Patch 12 removes some redundant test cases. * Patches 14-17 expand on existing test coverage.

[PATCH net-next v2] selftests: net: local_termination: annotate the expected failures

by Jakub Kicinski

Vladimir said when adding this test: The bridge driver fares particularly badly [...] mainly because it does not implement IFF_UNICAST_FLT. See commit 90b9566aa5cd ("selftests: forwarding: add a test for local_termination.sh"). We don't want to hide the known gaps, but having a test which always fails prevents us from catching regressions. Report the cases we know may fail as XFAIL.

by Matthieu Baerts (NGI0)

In this series from Geliang, modifying MPTCP BPF selftests, we have: - SIGINT support - A new macro to reduce duplicated code - A new MPTCP subflow BPF program setting socket options per subflow: it looks better to have this old test program in the BPF selftests to track regressions and to serve as example. Note: Nicolas is no longer working for Tessares, but he did this work while working for them, and his email address is no longer available. - A new MPTCP BPF subtest validating the new BPF program.

[PATCH net] selftests: net: move amt to socat for better compatibility

by Jakub Kicinski

The test seems to expect that nc will exit after the first received message. This is not the case with Ncat 7.94. There are multiple versions of nc out there, switch to socat for better compatibility. Tell socat to exit after 128 bytes and pad the message. Since the test sets -e make sure we don't set exit code (|| true) and print the pass / fail rather then silently moving over the test and just setting non-zero exit code with no output indicating what failed.

[PATCH net-next 1/2] selftests: net: fix timestamp not arriving in cmsg_time.sh

by Jakub Kicinski

On slow machines the SND timestamp sometimes doesn't arrive before we quit. The test only waits as long as the packet delay, so it's easy for a race condition to happen. Double the wait but do a bit of polling, once the SND timestamp arrives there's no point to wait any longer.
