From: Eric Dumazet <edumazet@google.com> stable inclusion from linux-4.19.211 commit 198d4e60e932f59bc8555afb015b90e8c898ac1b -------------------------------- [ Upstream commit dbe0b88064494b7bb6a9b2aa7e085b14a3112d44 ] bridge_fill_linkxstats() is using nla_reserve_64bit(). We must use nla_total_size_64bit() instead of nla_total_size() for corresponding data structure.
