Description Cristian Ciupitu 2011-05-11 08:45:16 UTC 
Description of problem:
I'm getting SELinux denials when various programs, e.g. BIND, DHCP try to use IPv6.

Version-Release number of selected component (if applicable):
selinux-policy-3.9.7-40.fc14.noarch.rpm

How reproducible:
Every time

Steps to Reproduce:
1. Disable IPv6 by creating /etc/modprobe.d/blacklist-ipv6.conf with the following content:
# taken from http://fedorasolved.org/network-solutions/disable-ipv6
install ipv6 /bin/true
blacklist ipv6
2. Run a program that tries to use IPv6, e.g. service dhcpd start

Actual results:
----

Expected results:
No denials.

Am I supposed to fix this by setting the domain_kernel_load_modules SELinux boolean?
