Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The 4.4.99 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the 4.4.99 stable release shall be applied:
* mac80211: accept key reinstall without changing anything
* mac80211: use constant time comparison with keys
