Subject: [PATCH] utils: nfsynproxy: fix build with musl libc
|
|
The musl libc exposes some struct tcphdr field only when _GNU_SOURCE is
|
defined. Fix the following build failure:
|
|
nfsynproxy.c: In function ‘parse_packet’:
|
nfsynproxy.c:34:9: error: ‘const struct tcphdr’ has no member named ‘syn’
|
if (!th->syn || !th->ack)
|
^
|
nfsynproxy.c:34:21: error: ‘const struct tcphdr’ has no member named ‘ack’
|
if (!th->syn || !th->ack)
|
^
|
nfsynproxy.c:42:8: error: ‘const struct tcphdr’ has no member named ‘res2’
|
if (th->res2 == 0x1)
|
^
|
nfsynproxy.c:45:13: error: ‘const struct tcphdr’ has no member named ‘doff’
|
length = th->doff * 4 - sizeof(*th);
|
^
