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 following upstream stable patches should be included in the Ubuntu kernel: 4.4.217 upstream stable release from git://git.kernel.org/ Linux 4.4.217 ipv4: ensure rcu_read_lock() in cipso_v4_error()
