Subject: [PATCH bpf-next 8/9] selftests/bpf: Use netns helpers in lwt tests
Date: Wed, 15 May 2024 13:59:35 +0800	[thread overview]
Message-ID: <92f1fe99018b50a92fedd7ce68abcb744f49d1cf.1715751995.git.tanggeliang@kylinos.cn> (raw)
In-Reply-To: <cover.1715751995.git.tanggeliang@kylinos.cn>

From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses netns helpers create_netns() and cleanup_netns() in
lwt_helpers.h instead of using the local function netns_create() and
netns_delete().

For using these helpers. network_helpers.h needs to be included in
lwt_helpers.h. Then '#include "network_helpers.h"' in lwt_redirect.c
and lwt_reroute.c can be dropped.

Signed-off-by: Geliang Tang <tanggeliang@kylinos.cn>
