That means the change will land in 4.14 at the earliest, right? (Just
out of curiosity.)

By the way, refpolicy only grants "socket" permissions to a handful of
domains, all of which also have the corresponding "unix_dgram_socket"
permissions. The fedora policy does the same (according to Stephen);
this only leaves custom policies to be potentially affected by this
change.

Given that the SOCK_RAW->SOCK_DGRAM translation is obscure enough not to
be documented anywhere outside the kernel sources, I doubt there are
many users of it, anyway.
