selftests/bpf: fix compile errors due to unsync linux/in6.h and netinet/in.h
I meet below compile errors:
"
In file included from test_tcpnotify_kern.c:12:
/usr/include/netinet/in.h:101:5: error: expected identifier
IPPROTO_HOPOPTS = 0, /* IPv6 Hop-by-Hop options. */
^
/usr/include/linux/in6.h:131:26: note: expanded from macro 'IPPROTO_HOPOPTS'
^
In file included from test_tcpnotify_kern.c:12:
/usr/include/netinet/in.h:103:5: error: expected identifier
IPPROTO_ROUTING = 43, /* IPv6 routing header. */
^
/usr/include/linux/in6.h:132:26: note: expanded from macro 'IPPROTO_ROUTING'
^
In file included from test_tcpnotify_kern.c:12:
/usr/include/netinet/in.h:105:5: error: expected identifier
IPPROTO_FRAGMENT = 44, /* IPv6 fragmentation header. */
^
/usr/include/linux/in6.h:133:26: note: expanded from macro 'IPPROTO_FRAGMENT'
"
The same compile errors are reported for test_tcpbpf_kern.c too.
My environment:
lsb_release -a:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.6 LTS
Release: 16.04
Codename: xenial
dpkg -l | grep libc-dev:
ii libc-dev-bin 2.23-0ubuntu11 amd64 GNU C Library: Development binaries
ii linux-libc-dev:amd64 4.4.0-145.171 amd64 Linux Kernel Headers for development.
The reason is linux/in6.h and netinet/in.h aren't synchronous about how to
handle the same definitions, IPPROTO_HOPOPTS, etc.
This patch fixes the compile errors by moving <netinet/in.h> to before the
<linux/*.h>.
