Subject: [PATCH 6.7 239/641] rxrpc: Fix skbuff cleanup of calls recvmsg_queue and rx_oos_queue
Date: Mon, 22 Jan 2024 15:52:23 -0800	[thread overview]
Message-ID: <20240122235825.406423043@linuxfoundation.org> (raw)
In-Reply-To: <20240122235818.091081209@linuxfoundation.org>

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

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

From: David Howells <dhowells@redhat•com>

[ Upstream commit 4fc68c4c1a114ba597b4f3b082f04622dfa0e0f6 ]

Fix rxrpc_cleanup_ring() to use rxrpc_purge_queue() rather than
skb_queue_purge() so that the count of outstanding skbuffs is correctly
updated when a failed call is cleaned up.

Without this rmmod may hang waiting for rxrpc_n_rx_skbs to become zero.

Fixes: 5d7edbc9231e ("rxrpc: Get rid of the Rx ring")
