Subject: [PATCH 4.9 159/171] 6pack,mkiss: fix possible deadlock
Date: Thu, 2 Jan 2020 23:08:10 +0100 [thread overview]
Message-ID: <20200102220608.860055476@linuxfoundation.org> (raw)
In-Reply-To: <20200102220546.960200039@linuxfoundation.org>
From: Eric Dumazet <edumazet@google.com>
commit 5c9934b6767b16ba60be22ec3cbd4379ad64170d upstream.
We got another syzbot report [1] that tells us we must use
write_lock_irq()/write_unlock_irq() to avoid possible deadlock.
