babeld should run as zebra_t, which is used by other quagga daemons.
If we decide to run babeld as zebra_t then the definition of zebra_port_t must be extended - it must include port 2609. Otherwise following AVC appears: ---- type=SOCKADDR msg=audit(11/14/2013 08:22:47.294:700) : saddr=inet host:127.0.0.1 serv:2609 type=SYSCALL msg=audit(11/14/2013 08:22:47.294:700) : arch=x86_64 syscall=bind success=no exit=-13(Permission denied) a0=0x5 a1=0x7f6b9a9f5d20 a2=0x10 a3=0x7fffee09969c items=0 ppid=1 pid=20264 auid=unset uid=quagga gid=quagga euid=quagga suid=quagga fsuid=quagga egid=quagga sgid=quagga fsgid=quagga tty=(none) ses=unset comm=babeld exe=/usr/sbin/babeld subj=system_u:system_r:zebra_t:s0 key=(null) type=AVC msg=audit(11/14/2013 08:22:47.294:700) : avc: denied { name_bind } for pid=20264 comm=babeld src=2609 scontext=system_u:system_r:zebra_t:s0 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket ----
