	Change tests that often fails in parallel execution mode to serial. Signed-off-by: Yucong Sun <sunyucong@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20211006185619.364369-15-fallentree@fb.com
2021-04-15	selftests/bpf: Silence clang compilation warnings	Yonghong Song	1	-2/+2
	With clang compiler: make -j60 LLVM=1 LLVM_IAS=1 <=== compile kernel make -j60 -C tools/testing/selftests/bpf LLVM=1 LLVM_IAS=1 Some linker flags are not used/effective for some binaries and we have warnings like: warning: -lelf: 'linker' input unused [-Wunused-command-line-argument] We also have warnings like: .../selftests/bpf/prog_tests/ns_current_pid_tgid.c:74:57: note: treat the string as an argument to avoid this if (CHECK(waitpid(cpid, &wstatus, 0) == -1, "waitpid", strerror(errno))) ^ "%s", .../selftests/bpf/test_progs.h:129:35: note: expanded from macro 'CHECK' _CHECK(condition, tag, duration, format) ^ .../selftests/bpf/test_progs.h:108:21: note: expanded from macro '_CHECK' fprintf(stdout, ##format); \ ^ The first warning can be silenced with clang option -Wno-unused-command-line-argument. For the second warning, source codes are modified as suggested by the compiler to silence the warning. Since gcc does not support the option -Wno-unused-command-line-argument and the warning only happens with clang compiler, the option -Wno-unused-command-line-argument is enabled only when clang compiler is used.

2021-01-20	bpf, selftests: Fold test_current_pid_tgid_new_ns into test_progs.	Carlos Neira	1	-58/+60
	Currently tests for bpf_get_ns_current_pid_tgid() are outside test_progs. This change folds test cases into test_progs. Changes from v11: - Fixed test failure is not detected. - Removed EXIT(3) call as it will stop test_progs execution.

2020-04-28	selftests/bpf: Fix bpf_link leak in ns_current_pid_tgid selftest	Andrii Nakryiko	1	-4/+1
	If condition is inverted, but it's also just not necessary. Fixes: 1c1052e0140a ("tools/testing/selftests/bpf: Add self-tests for new helper bpf_get_ns_current_pid_tgid.")
