Title:
  mac80211_hwsim unable to handle kernel NULL pointer dereference
  at0000000000000000

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released
Status in linux source package in Cosmic:
  Fix Released

Bug description:
  [Impact]
  Kernel NULL pointer dereference in mac80211_hwsim.

  [Fix]
  a1881c9b8a1e mac80211_hwsim: Timer should be initialized before device 
registered

  This fix has been included in 4.19.9 or above.

  [Test Case]
  $ git clone https://github.com/aircrack-ng/aircrack-ng
  # Tested with 69a406c
  $ cd aircrack-ng
  $ grep 'sudo apt' README.md | bash
  $ autoreconf -i
  $ ./configure --with-experimental
  $ make check
  $ sudo bash scripts/airmon-ng.linux check kill
  $ sudo make integration

  # Run integration test again and check dmesg
  $ sudo bash scripts/airmon-ng.linux check kill
  $ sudo make integration

  Verified with VMs setup locally.

  [Regression Risk]
  Low. Move forward data structure initialization only. This patch has
  also been included in LTS stable kernel.

  ==== Original Bug Report ====

  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
