The queueis built to be wait-free even when there are multiple consumers, andthe parallel selftest provides a signal on whether the queue behavescorrectly when stress tested.To support the test, this patch includes a test harness for parallelselftests. The spmc selftest acts as an example of the naming and otherconventions expected by the harness.Signed-off-by: Emil Tsalapatis <emil@etsalapatis.com>Link: https://lore.kernel.org/r/20260605222020.5231-4-emil@etsalapatis.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/prog_tests/libarena.c Sat, 06 Jun 2026 00:20:20 +0200 Emil Tsalapatis <emil@etsalapatis.com> http://kernelsources.org:8080/source/history/linux/tools/testing/selftests/bpf/prog_tests/libarena.c#b1487dc1b181ad6aaea95357030a421bb180d8e7 selftests/bpf: Add selftests for libarena buddy allocatorIntroduce selftests for the buddy allocator with and withoutASAN. Add the libarena selftests both to the libarena testrunner and to test_progs, so that they are a) available whenlibarena is pulled as a standalone library, and b) exercisedalong with all other test programs in this directory.ASAN for libarena requires LLVM 22. Add logic in the top-levelselftests Makefile to only compile the ASAN variant if thecompiler supports it, otherwise skip the test.Signed-off-by: Emil Tsalapatis <emil@etsalapatis.com>Link: https://lore.kernel.org/r/20260426190338.4615-8-emil@etsalapatis.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/prog_tests/libarena.c Sun, 26 Apr 2026 21:03:37 +0200 Emil Tsalapatis <emil@etsalapatis.com>
