Description Paul Bransford 2013-01-11 15:53:42 UTC 
Description of problem:
SELinux is preventing /usr/bin/icecast from name_bind access on the tcp_socket. But only if a port other than 8000 has been configured.

Version-Release number of selected component (if applicable):
2.3.3.1.el6.x86_64

How reproducible:
100% reproducible

Steps to Reproduce:
1. install icecast via epel repository
2. leave SELinux in enforcing mode
3. edit "/etc/icecast.xml" and configure icecast to bind a port other than 8000
3. attempt to start icecast daemon
  
Actual results:
Icecast daemon starts but is unable to create the listening TCP socket

Expected results:
Icecast daemon starts with normal operation, provided port is > 1024. If port is <= 1024, access would be denied via normal non-selinux means due to root restriction on those ports.

Additional info:
I have Icecast configured to bind on all interfaces, the port 8080, which is not a restricted low-level port. The default port, 8000, will work.

sealert parsing of audit log:

SELinux is preventing /usr/bin/icecast from name_bind access on the tcp_socket .

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that icecast should be allowed name_bind access on the  tcp_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 icecast /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
