selftests/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK

2022-04-11T03:17:16Z

We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now. After this change, the header tools/testing/selftests/bpf/bpf_rlimit.h can be removed. This patch also removes the useless header sys/resource.h from many files in tools/testing/selftests/bpf/.

tools/bpf: adjust rlimit RLIMIT_MEMLOCK for test_verifier_log

2017-11-30T18:55:18Z

The default rlimit RLIMIT_MEMLOCK is 64KB. In certain cases, e.g. in a test machine mimicking our production system, this test may fail due to unable to charge the required memory for prog load: # ./test_verifier_log Test log_level 0... ERROR: Program load returned: ret:-1/errno:1, expected ret:-1/errno:22 Changing the default rlimit RLIMIT_MEMLOCK to unlimited makes the test always pass.

Add a test for verifier log handling. Check bad attr combinations but focus on cases when log is truncated. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Acked-by: Alexei Starovoitov Acked-by: Daniel Borkmann Signed-off-by: David S. Miller
