Comment 1 Zdenek Pytela 2017-02-07 14:05:05 UTC
Description of problem:
SELinux policy prevents legacy commands iptables.init and ip6tables.init from accessing /etc/modprobe.d directory.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. systemctl start ip6tables
2. systemctl status ip6tables
3. ausearch -i -ts recent

Actual results:
type=SYSCALL msg=audit(02/07/17 14:55:51.092:2378) : arch=x86_64 syscall=openat success=no exit=EACCES(Permission denied) a0=0xffffffffffffff9c a1=0x1b76e50 a2=O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC a3=0x0 items=0 ppid=1 pid=9434 auid=unset uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=(none) ses=unset comm=ip6tables.init exe=/usr/bin/bash subj=system_u:system_r:iptables_t:s0 key=(null)

Expected results:
<no avc>

Additional info:
seems similar to #1373220
