Subject: [PATCH bpf-next 08/14] selftests/bpf: Use connect_to_addr in test_sock_addr
Date: Wed, 10 Apr 2024 15:29:41 +0800	[thread overview]
Message-ID: <ac291aceeb72b2a7ac7b1cd165022793094ea58f.1712733999.git.tanggeliang@kylinos.cn> (raw)
In-Reply-To: <cover.1712733999.git.tanggeliang@kylinos.cn>

From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses public helper connect_to_addr() exported in
network_helpers.h instead of the local defined function connect_to_server()
in test_sock_addr.c. This can avoid duplicate code.
