Subject: [PATCH net 1/2] net: bridge: use nla_total_size_64bit() in br_get_linkxstats_size()
Date: Mon, 4 Oct 2021 18:05:07 -0700 [thread overview]
Message-ID: <20211005010508.2194560-2-eric.dumazet@gmail.com> (raw)
In-Reply-To: <20211005010508.2194560-1-eric.dumazet@gmail.com>
From: Eric Dumazet <edumazet@google•com>
bridge_fill_linkxstats() is using nla_reserve_64bit().
We must use nla_total_size_64bit() instead of nla_total_size()
for corresponding data structure.
Fixes: 1080ab95e3c7 ("net: bridge: add support for IGMP/MLD stats and export them via netlink")
