selftests/bpf: Fix bind{4,6} tcp/socket header type conflict

2022-08-29T15:00:41Z

There is a potential for us to hit a type conflict when including netinet/tcp.h with sys/socket.h, we can remove these as they are not actually needed. Fixes errors like the below when compiling with gcc BPF backend: In file included from /usr/include/netinet/tcp.h:91, from progs/bind4_prog.c:10: /home/buildroot/opt/cross/lib/gcc/bpf/13.0.0/include/stdint.h:34:23: error: conflicting types for 'int8_t'; have 'char' 34 | typedef __INT8_TYPE__ int8_t; | ^~~~~~ In file included from /usr/include/x86_64-linux-gnu/sys/types.h:155, from /usr/include/x86_64-linux-gnu/bits/socket.h:29, from /usr/include/x86_64-linux-gnu/sys/socket.h:33, from progs/bind4_prog.c:9: /usr/include/x86_64-linux-gnu/bits/stdint-intn.h:24:18: note: previous declaration of 'int8_t' with type 'int8_t' {aka 'signed char'} 24 | typedef __int8_t int8_t; | ^~~~~~ /home/buildroot/opt/cross/lib/gcc/bpf/13.0.0/include/stdint.h:43:24: error: conflicting types for 'int64_t'; have 'long int' 43 | typedef __INT64_TYPE__ int64_t; | ^~~~~~~ /usr/include/x86_64-linux-gnu/bits/stdint-intn.h:27:19: note: previous declaration of 'int64_t' with type 'int64_t' {aka 'long long int'} 27 | typedef __int64_t int64_t; | ^~~~~~~ make: *** [Makefile:537: /home/buildroot/bpf-next/tools/testing/selftests/bpf/bpf_gcc/bind4_prog.o] Error 1 Signed-off-by: James Hilliard Signed-off-by: Daniel Borkmann Link: https://lore.kernel.org/bpf/20220826052925.980431-1-james.hilliard1@gmail.com

selftests/bpf: Extend bind{4,6} programs with a call to bpf_setsockopt

selftests/bpf: Rewrite test_sock_addr bind bpf into C

I'm planning to extend it in the next patches. It's much easier to work with C than BPF assembly. Signed-off-by: Stanislav Fomichev Signed-off-by: Alexei Starovoitov Acked-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20201202172516.3483656-2-sdf@google.com
