Subject: [PATCH bpf-next 3/5] selftests/bpf: Use start_server_addr in test_sock_addr
Date: Sat, 20 Apr 2024 19:55:41 +0800 [thread overview]
Message-ID: <05e46352d9ff930316119b349e43a17241497022.1713613543.git.tanggeliang@kylinos.cn> (raw)
In-Reply-To: <cover.1713613543.git.tanggeliang@kylinos.cn>
From: Geliang Tang <tanggeliang@kylinos.cn>
Include network_helpers.h in test_sock_addr.c, use the newly added public
helper start_server_addr() instead of the local defined function
start_server(). This can avoid duplicate code.
In order to use functions defined in network_helpers.c in test_sock_addr.c,
Makefile needs to be updated and <Linux/err.h> needs to be included in
network_helpers.h to avoid compilation errors.
