Subject: [Patch bpf-next v7 1/9] bpf: clean up sockmap related Kconfigs
Date: Tue, 23 Feb 2021 10:49:26 -0800	[thread overview]
Message-ID: <20210223184934.6054-2-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <20210223184934.6054-1-xiyou.wangcong@gmail.com>

From: Cong Wang <cong.wang@bytedance.com>

As suggested by John, clean up sockmap related Kconfigs:

Reduce the scope of CONFIG_BPF_STREAM_PARSER down to TCP stream
parser, to reflect its name.

Make the rest sockmap code simply depend on CONFIG_BPF_SYSCALL
and CONFIG_INET, the latter is still needed at this point because
of TCP/UDP proto update. And leave CONFIG_NET_SOCK_MSG untouched,
as it is used by non-sockmap cases.
