[PATCH bpf-next v5 3/6] selftests/bpf: Use start_server_addr in sk_assign

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Include network_helpers.h in prog_tests/sk_assign.c, use the newly
added public helper start_server_addr() instead of the local defined
function start_server(). This can avoid duplicate code.

The code that sets SO_RCVTIMEO timeout as timeo_sec (3s) can be dropped,
since start_server_addr() sets default timeout as 3s.
