2024-04-30selftests/bpf: Drop an unused local variableBenjamin Tissoires
Some copy/paste leftover, this is never used. Fixes: e3d9eac99afd ("selftests/bpf: wq: add bpf_wq_init() checks") Signed-off-by: Benjamin Tissoires <bentiss@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/bpf/20240430-bpf-next-v3-3-27afe7f3b17c@kernel.org
2024-04-24selftests/bpf: Fix wq test.Alexei Starovoitov
The wq test was missing destroy(skel) part which was causing bpf progs to stay loaded. That was causing test_progs to complain with "Failed to unload bpf_testmod.ko from kernel: -11" message, but adding destroy() wasn't enough, since wq callback may be delayed, so loop on unload of bpf_testmod if errno is EAGAIN.

We simply try in all supported map types if we can store/load a bpf_wq. Signed-off-by: Benjamin Tissoires <bentiss@kernel.org> Link: https://lore.kernel.org/r/20240420-bpf_wq-v2-10-6c986a5a741f@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
