Subject: conntrack-tools: add patch to fix build with musl
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=07283e6ad5303e057d91c9211013d34c566fa61f;p=buildroot.git

conntrack-tools: add patch to fix build with musl

The conntrack-tools sources use the GNU version of 'struct tcphdr',
which is not exposed by the musl headers unless _GNU_SOURCE is defined.

The included patch adds the missing definition to 'src/helpers/rpc.c'.

Fixes:

+Subject: [PATCH] src: fix build with musl libc
+
+The GNU version of 'struct tcphdr' is not exposed by musl libc headers
+unless _GNU_SOURCE is defined. Without this definition, the build fails
+with:
+
+  rpc.c: In function 'rpc_helper_cb':
+  rpc.c:351:15: error: 'struct tcphdr' has no member named 'doff'
+     offset += th->doff * 4;
+                 ^

+Upstream status: sent
