Subject: [PATCH 0/2] net: fix use-after-free bugs
Date: Wed,  4 Aug 2021 18:48:57 +0300	[thread overview]
Message-ID: <cover.1628091954.git.paskripkin@gmail.com> (raw)

I've added new checker to smatch yesterday. It warns about using
netdev_priv() pointer after free_{netdev,candev}() call. I hope, it will
get into next smatch release.

Some of the reported bugs are fixed and upstreamed already, but Dan ran new
smatch with allmodconfig and found 2 more. Big thanks to Dan for doing it,
because I totally forgot to do it.

Pavel Skripkin (2):
  net: fec: fix use-after-free in fec_drv_remove
  net: vxge: fix use-after-free in vxge_device_unregister
