selftests/bpf: tcpbpf_kern: use in6_* macros from glibc
Both glibc and the kernel have in6_* macros definitions. Build fails because it picks up wrong in6_* macro from the kernel header and not the header from glibc. Fixes build error below: clang -I. -I./include/uapi -I../../../include/uapi -Wno-compare-distinct-pointer-types \ -O2 -target bpf -emit-llvm -c test_tcpbpf_kern.c -o - | \ llc -march=bpf -mcpu=generic -filetype=obj -o .../tools/testing/selftests/bpf/test_tcpbpf_kern.o In file included from test_tcpbpf_kern.c:12: .../netinet/in.h:101:5: error: expected identifier IPPROTO_HOPOPTS = 0, /* IPv6 Hop-by-Hop options. */ ^ .../linux/in6.h:131:26: note: expanded from macro 'IPPROTO_HOPOPTS' ^ In file included from test_tcpbpf_kern.c:12: /usr/include/netinet/in.h:103:5: error: expected identifier IPPROTO_ROUTING = 43, /* IPv6 routing header. */ ^ .../linux/in6.h:132:26: note: expanded from macro 'IPPROTO_ROUTING' ^ In file included from test_tcpbpf_kern.c:12: .../netinet/in.h:105:5: error: expected identifier IPPROTO_FRAGMENT = 44, /* IPv6 fragmentation header. */ ^ Since both glibc and the kernel have in6_* macros definitions, use the one from glibc. Kernel headers will check for previous libc definitions by including include/linux/libc-compat.h.
