Subject: [PATCH v3] netfilter: nf_conntrack_bridge: Fix memory leak when error
Date: Thu, 29 Jul 2021 16:20:21 +0800 [thread overview]
Message-ID: <20210729082021.14407-1-yajun.deng@linux.dev> (raw)
It should be added kfree_skb_list() when err is not equal to zero
in nf_br_ip_fragment().
v2: keep this aligned with IPv6.
v3: modify iter.frag_list to iter.frag.
Fixes: 3c171f496ef5 ("netfilter: bridge: add connection tracking system")
Signed-off-by: Yajun Deng <yajun.deng@linux.dev>
