Description Adam Tkac 2007-04-24 06:20:23 EDT
Description of problem:
by default context (system_u:object_r:ndc_exec_t) rndc is not able to connect to
named (system_u:object_r:named_exec_t). I set contexts by restorecon utility.
When I tried set rndc's context with "chcon --reference /usr/sbin/named" all
works fine. 

Version-Release number of selected component (if applicable):
rpm -q selinux-policy
selinux-policy-2.5.12-5.fc7

How reproducible:
always

Steps to Reproduce:
1. restorecon /usr/sbin/rndc
2. restorecon /usr/sbin/named
3. try run "rndc status" to get status of named

Actual results:
see nice output: "rndc: bind socket: permission denied"

Expected results:
controling server through rndc (server control utility)

Additional info:
as I wrote upper, after "chcon --reference /usr/sbin/named /usr/sbin/rndc" all
works fine.

What avc's were you seeing before the chcon?
Comment 2 Adam Tkac 2007-04-24 10:29:05 EDT
This is in log. I'm not selinux expert so problem could be in bind package or my
configuration :)

Latest policy should have this fixed.

selinux-policy-2.6.1-1.fc7

Yeah. I've compiled latest selinux-policy from CVS and all works fine. Closing
