Topi Miettinen da3bbc31a8 semanage: handle getprotobyname() failure case
At least on Debian, /etc/protocols, which is used by
socket.getprotobyname() to resolve protocols to names, does not
contain an entry for "ipv4". In that case, set the protocol number
used by audit logs for "ipv4" to a fixed value. To ensure audit log
compatibility, let's use the same numeric value as Fedora: 4, which is
actually understood by kernel as IP over IP.
