Subject: [PATCH 4.15 28/72] ipv6: fix possible deadlock in rt6_age_examine_exception()
Date: Fri,  6 Apr 2018 15:24:03 +0200	[thread overview]
Message-ID: <20180406084351.690409782@linuxfoundation.org> (raw)
In-Reply-To: <20180406084349.367583460@linuxfoundation.org>

4.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@google.com>

commit 1bfa26ff8c4b7512f4e4efa6df211239223033d4 upstream.

syzbot reported a LOCKDEP splat [1] in rt6_age_examine_exception()

rt6_age_examine_exception() is called while rt6_exception_lock is held.
This lock is the lower one in the lock hierarchy, thus we can not
call dst_neigh_lookup() function, as it can fallback to neigh_create()

We should instead do a pure RCU lookup. As a bonus we avoid
a pair of atomic operations on neigh refcount.

[1]

WARNING: possible circular locking dependency detected

syz-executor7/4015 is trying to acquire lock:
 (&ndev->lock){++--}, at: [<00000000416dce19>] __ipv6_dev_mc_dec+0x45/0x350 net/ipv6/mcast.c:928

but task is already holding lock:
 (&tbl->lock){++-.}, at: [<00000000b5cb1d65>] neigh_ifdown+0x3d/0x250 net/core/neighbour.c:292

which lock already depends on the new lock.
