2b164c15fd ("cfg80211: support reloading regulatory database"): BUG: unable to handle kernel NULL pointer dereference at (null)
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next.git regulatory
commit 2b164c15fd93148a1a0706dea1a866c274b55d87
Author: Johannes Berg <johannes.berg(a)intel.com>
AuthorDate: Wed Sep 13 16:07:22 2017 +0200

cfg80211: support reloading regulatory database
If the regulatory database is loaded, and then updated, it may
be necessary to reload it. Add an nl80211 command to do this.
NOTE: this doesn't do anything at all due to the firmware cache.

Hi Andy,
Your patch triggers the warning (not 100% reproducible) with the
attached kconfig and KVM reproduce script. It may be relevant to an
old bug though, since the dmesg is not clean and contains another BUG
trace dump.
