Hello to the list,

I start from here because there are some news, this is the story:

I upgrade one server from Centos 6.3 to 6.5 and come back out again the problem described above, so I use
restorecon -Rv /sbin
but there is not output, this was strange, I reboot the server and shorewall won't start again, i try some hacks but nothing.
So i tried to change selinux in permissive mode and shorewall START!!
I look at files:

ls -Z /sbin/ip*

and the surprise

-rwxr-xr-x. root root unconfined_u:object_r:bin_t:s0 /sbin/ip6tables-multi-1.4.7
-rwxr-xr-x. root root unconfined_u:object_r:bin_t:s0 /sbin/iptables-multi-1.4.7

the selinux label was wrong so I look in the /etc/selinux/targeted/contexts/files/file_contexts file for the label

cat /etc/selinux/targeted/contexts/files/file_contexts | grep ip

and i don't find nothing, this was very very strange so I open manually the file and SURPRISE!!	 what i find:

/sbin/ebtables  --      system_u:object_r:iptables_exec_t:s0
/sbin/ebtables-restore  --      system_u:object_r:iptables_exec_t:s0

look!! ebtables and not iptables............................. if i use restorecon -Rv /sbin did not work because the label was wrong.....
I find the same problem in a server running RedHat 6.5 but had not come out because I had upgraded from 6.4 to 6.5

[FIX]
I relabel manually the two files with this commands:
chcon -t iptables_exec_t /sbin/iptables-multi-1.4.7
chcon -t iptables_exec_t /sbin/ip6tables-multi-1.4.7
but i hope that the /etc/selinux/targeted/contexts/files/file_contexts will updated soon.

I hope that this can help someone
Thanks
Amedeo
