FYI, I just merged that patch into the selinux/next tree.

   selinux: avoid dereferencing the policy prior to initialization

   Certain SELinux security server functions (e.g. security_port_sid,
   called during bind) were not explicitly testing to see if SELinux
   has been initialized (i.e. initial policy loaded) and handling
   the no-policy-loaded case.  In the past this happened to work
   because the policydb was statically allocated and could always
   be accessed, but with the recent encapsulation of policy state
   and conversion to dynamic allocation, we can no longer access
   the policy state prior to initialization.  Add a test of
   !selinux_initialized(state) to all of the exported functions that
   were missing them and handle appropriately.

   Fixes: 461698026ffa ("selinux: encapsulate policy state, refactor ...")

Thanks.

I will add that to the selinux tree merge in linux-next until it turns
up in the tree.
