Add this definition to fix errors seen compiling for mips64el/musl-libc: flow_dissector.c:118:30: error: 'struct tcphdr' has no member named 'doff' 118 | .tcp.doff = 5, | ^~~~ flow_dissector.c:119:30: error: 'struct tcphdr' has no member named 'source' 119 | .tcp.source = 80, | ^~~~~~ flow_dissector.c:120:30: error: 'struct tcphdr' has no member named 'dest' 120 | .tcp.dest = 8080, | ^~~~ Fixes: ae173a915785 ("selftests/bpf: support BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG") Signed-off-by: Tony Ambardar Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/8f7ab21a73f678f9cebd32b26c444a686e57414d.1721713597.git.tony.ambardar@gmail.com --- diff --git a/tools/testing/selftests/bpf/prog_tests/flow_dissector.c b/tools/testing/selftests/bpf/prog_tests/flow_dissector.c index 9625e6d217913..3171047414a7d 100644 --- a/tools/testing/selftests/bpf/prog_tests/flow_dissector.c +++ b/tools/testing/selftests/bpf/prog_tests/flow_dissector.c @@ -1,4 +1,5 @@ // SPDX-License-Identifier: GPL-2.0 +#define _GNU_SOURCE #include #include #include
