This is a note to let you know that I've just added the patch titled net: bridge: use nla_total_size_64bit() in br_get_linkxstats_size() to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-bridge-use-nla_total_size_64bit-in-br_get_linkxs.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit a9f39705140a7a0c0e452e724b24dc5dfa77376c Author: Eric Dumazet <edumazet@xxxxxxxxxx> Date: Mon Oct 4 18:05:07 2021 -0700 net: bridge: use nla_total_size_64bit() in br_get_linkxstats_size() [ 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.
