Subject: [PATCH net 0/4] net-sysfs: check device is present when showing paths
Date: Wed, 24 Jul 2024 11:46:49 +1000	[thread overview]
Message-ID: <cover.1721784184.git.jamie.bainbridge@gmail.com> (raw)

A sysfs reader can race with a device reset or removal.

This was fixed for speed_show with commit 4224cfd7fb65 ("net-sysfs: add
check for netdevice being present to speed_show") so add the same check
to carrier, duplex, testing, and dormant paths.

Submitting as separate patches to make Fixes reporting accurate.
