Still missing at this point: - filtering out non-established sockets - trivial: SACK_PERM and timestamps (I forgot, we don't support them guest-side but they're relevant for sockets) - reasonable error handling, including not failing a migration on the target when it's anyway too late, or not crashing if we can't bind() or connect() a socket - tests with half-closed sockets The new SELinux rule is still untested.
