Title:
mac80211_hwsim unable to handle kernel NULL pointer dereference
at0000000000000000
Status in linux package in Ubuntu:
Incomplete
Bug description:
The issue happens on 16.04 with linux-image-4.15.0-47-generic (as well
as linux-image-4.15.0-45-generic). It also happens with linux-
image-4.15.0-47-generic on 18.04 as well as the HWE kernel
(4.18.0-17-generic). All test were done on 64 bit in a virtual machine
and can be reproduced. It doesn't happen on 18.10 (mac80211_hwsim has
other issues on this kernel that are solved in 19.04, most likely
unrelated to this) or 19.04.

How to reproduce:
git clone https://github.com/aircrack-ng/aircrack-ng
# Tested with 69a406c
cd aircrack-ng
grep 'sudo apt' README.md > a && bash a
rm a
autoreconf -i
./configure --with-experimental
make check
bash scripts/airmon-ng.linux check kill
make integration
It will freeze after the test/test-aireplay-ng-0007.sh (while running
test/test-airbase-ng-0001.sh) test while doing "modprobe
mac80211_hwsim radios=2". You may have to run them twice before this
happens
