Description trustedsubject 2013-01-03 19:11:12 EST

Description of problem:

When running MLS policy, SELinux generates AVC for lldpad as per previous bug: 723958.

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

selinux-policy-mls-3.7.19-154.el6

How reproducible:

Create minimal install of EL 6.3, and apply MLS policy as per slightly modified process from: http://fedoraproject.org/wiki/SELinux/FedoraMLSHowto

Steps to Reproduce:
1. yum update
2. reboot
3. yum install selinux-policy-mls
4. change /etc/sysconfig/selinux values to SELINUX=permissive and SELINUXTYPE=mls
5. touch /.autorelabel
6. reboot
7. give grub kernel argument '1' to boot into single user mode
8. change /etc/sysconfig/selinux value for SELINUX back to 'enforcing'
9. reboot

Actual results:

audit2allow generates the following policy for lldpad from the audit log:

allow initrc_t self:netlink_route_socket nlmsg_write;
allow initrc_t self:packet_socket { bind create ioctl setopt };
allow initrc_t self:shm { write unix_read unix_write associate read create };

Comment 2 Miroslav Grepl 2013-01-04 08:21:16 EST

initrc_t should not exist in MLS. You can allow it by these rules for now. We need to turn on lldpad policy in MLS.

Comment 4 Miroslav Grepl 2013-08-06 08:24:55 EDT

I back ported policy and made it as unconfined.

Comment 8 Miroslav Grepl 2013-08-27 10:16:28 EDT

Ok, it has been added only for targeted policy. Is lldpad needed on MLS system?

Comment 11 Milos Malik 2013-10-22 08:40:57 EDT

lldpad works in targeted policy, but does not have a special SELinux domain in MLS policy now. There will be another bug filed for this purpose.
