Subject: [PATCH 4.9 162/171] hrtimer: Annotate lockless access to timer->state
Date: Thu, 2 Jan 2020 23:08:13 +0100 [thread overview]
Message-ID: <20200102220609.318991775@linuxfoundation.org> (raw)
In-Reply-To: <20200102220546.960200039@linuxfoundation.org>
From: Eric Dumazet <edumazet@google.com>
commit 56144737e67329c9aaed15f942d46a6302e2e3d8 upstream.
syzbot reported various data-race caused by hrtimer_is_queued() reading
timer->state. A READ_ONCE() is required there to silence the warning.
Also add the corresponding WRITE_ONCE() when timer->state is set.
In remove_hrtimer() the hrtimer_is_queued() helper is open coded to avoid
loading timer->state twice.
KCSAN reported these cases:
