Subject: [PATCH] xtables-monitor: fix build with musl libc
|
|||
|
|
|
|||
|
|
Commit 7c8791edac3 ("xtables-monitor: fix build with older glibc")
|
|||
|
|
changed the code to use GNU style tcphdr fields. Unfortunately, musl
|
|||
|
|
libc requires _GNU_SOURCE definition to expose these fields.
|
|||
|
|
|
|||
|
|
Fix the following build failure:
|
|||
|
|
|
|||
|
|
xtables-monitor.c: In function ‘trace_print_packet’:
|
|||
|
|
xtables-monitor.c:406:43: error: ‘const struct tcphdr’ has no member named ‘source’
|
|||
|
|
printf("SPORT=%d DPORT=%d ", ntohs(tcph->source), ntohs(tcph->dest));
|
|||
|
|

xtables-monitor.c:406:64: error: ‘const struct tcphdr’ has no member named ‘dest’
|

printf("SPORT=%d DPORT=%d ", ntohs(tcph->source), ntohs(tcph->dest));
