Bug 990974

Description of problem:
SELinux is preventing /usr/sbin/unbound-anchor from 'name_bind' accesses on the udp_socket .

*****  Plugin bind_ports (92.2 confidence) suggests  *************************

If you want to allow /usr/sbin/unbound-anchor to bind to network port 26783
Then you need to modify the port type.
Do
# semanage port -a -t  -p udp 26783

*****  Plugin catchall_boolean (7.83 confidence) suggests  *******************

If you want to allow system to run with NIS
Then you must tell SELinux about this by enabling the 'nis_enabled' boolean.
You can read 'None' man page for more details.
Do
setsebool -P nis_enabled 1

*****  Plugin catchall (1.41 confidence) suggests  ***************************

If you believe that unbound-anchor should be allowed name_bind access on the  udp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep unbound-anchor /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
