Commit Message

Geliang Tang July 8, 2024, 2:29 a.m. UTC 
From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses public helper connect_fd_to_fd() exported in
network_helpers.h instead of using getsockname() + connect() in
run_lookup_prog() in prog_tests/sk_lookup.c. This can simplify
the code.
