Subject: [PATCH nf] netfilter: iptable_raw: drop bogus net_init annotation
Date: Fri, 17 Sep 2021 11:56:25 +0200 [thread overview]
Message-ID: <20210917095625.1338-1-fw@strlen.de> (raw)
This is a leftover from the times when this function was wired up via
pernet_operations. Now its called when userspace asks for the table.
With CONFIG_NET_NS=n, iptable_raw_table_init memory has been discarded
already and we get a kernel crash.
Other tables are fine, __net_init annotation was removed already.
Fixes: fdacd57c79b7 ("netfilter: x_tables: never register tables by default")
Reported-by: youling 257 <youling257@gmail.com>
