Subject: [PATCH 5.9 045/255] can: rx-offload: dont call kfree_skb() from IRQ context
Date: Tue, 17 Nov 2020 14:03:05 +0100	[thread overview]
Message-ID: <20201117122141.142670302@linuxfoundation.org> (raw)
In-Reply-To: <20201117122138.925150709@linuxfoundation.org>

From: Marc Kleine-Budde <mkl@pengutronix.de>

[ Upstream commit 2ddd6bfe7bdbb6c661835c3ff9cab8e0769940a6 ]

A CAN driver, using the rx-offload infrastructure, is reading CAN frames
(usually in IRQ context) from the hardware and placing it into the rx-offload
queue to be delivered to the networking stack via NAPI.

In case the rx-offload queue is full, trying to add more skbs results in the
skbs being dropped using kfree_skb(). If done from hard-IRQ context this
results in the following warning:

This patch fixes the problem by replacing the kfree_skb() by
dev_kfree_skb_any(), as rx-offload might be called from threaded IRQ handlers
as well.
