tools/bpf: fix test_sockmap failure
On one of our production test machine, when running bpf selftest test_sockmap, I got the following error: # sudo ./test_sockmap libbpf: failed to create map (name: 'sock_map'): Operation not permitted libbpf: failed to load object 'test_sockmap_kern.o' libbpf: Can't get the 0th fd from program sk_skb1: only -1 instances ...... load_bpf_file: (-1) Operation not permitted ERROR: (-1) load bpf failed The error is due to not-big-enough rlimit struct rlimit r = {10 * 1024 * 1024, RLIM_INFINITY}; The test already includes "bpf_rlimit.h", which sets current and max rlimit to RLIM_INFINITY. Let us just use it. Signed-off-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
