Subject: [PATCH AUTOSEL 5.19 08/22] rxrpc: Fix local destruction being repeated
Date: Wed, 14 Sep 2022 05:00:49 -0400 [thread overview]
Message-ID: <20220914090103.470630-8-sashal@kernel.org> (raw)
In-Reply-To: <20220914090103.470630-1-sashal@kernel.org>
From: David Howells <dhowells@redhat.com>
[ Upstream commit d3d863036d688313f8d566b87acd7d99daf82749 ]
If the local processor work item for the rxrpc local endpoint gets requeued
by an event (such as an incoming packet) between it getting scheduled for
destruction and the UDP socket being closed, the rxrpc_local_destroyer()
function can get run twice. The second time it can hang because it can end
up waiting for cleanup events that will never happen.
