| H A D | setget_sockopt.c | diff f649f992deeeab020257b886e054cc407154cbfc Thu Sep 01 19:29:37 CDT 2022 Martin KaFai Lau <martin.lau@kernel.org> selftest/bpf: Add test for bpf_getsockopt()
This patch removes the __bpf_getsockopt() which directly
reads the sk by using PTR_TO_BTF_ID. Instead, the test now directly
uses the kernel bpf helper bpf_getsockopt() which supports all
the required optname now.
TCP_SAVE[D]_SYN and TCP_MAXSEG are not tested in a loop for all
the hooks and sock_ops's cb. TCP_SAVE[D]_SYN only works
in passive connection. TCP_MAXSEG only works when
it is setsockopt before the connection is established and
the getsockopt return value can only be tested after
the connection is established.
