Subject: [PATCH 5.14 170/172] netfilter: conntrack: serialize hash resizes and cleanups
Date: Mon, 4 Oct 2021 14:53:40 +0200 [thread overview]
Message-ID: <20211004125050.470578865@linuxfoundation.org> (raw)
In-Reply-To: <20211004125044.945314266@linuxfoundation.org>
From: Eric Dumazet <edumazet@google.com>
commit e9edc188fc76499b0b9bd60364084037f6d03773 upstream.
Syzbot was able to trigger the following warning [1]
No repro found by syzbot yet but I was able to trigger similar issue
by having 2 scripts running in parallel, changing conntrack hash sizes,
and:
for j in `seq 1 1000` ; do unshare -n /bin/true >/dev/null ; done
It would take more than 5 minutes for net_namespace structures
to be cleaned up.
This is because nf_ct_iterate_cleanup() has to restart everytime
a resize happened.
By adding a mutex, we can serialize hash resizes and cleanups
and also make get_next_corpse() faster by skipping over empty
buckets.
Even without resizes in the picture, this patch considerably
speeds up network namespace dismantles.
