Description lance dillon 2012-06-18 20:15:45 EDT

Description of problem:
sssd unable to create pipes under /var/lib/sss/pipes, or read krb5 cache file in /tmp

Version-Release number of selected component (if applicable):
1.5.1-49.1

How reproducible:
install ipa-client, or service sssd start/restart

Comment 1 lance dillon 2012-06-18 20:18:14 EDT

The following policy file solved the problem for me:

policy_module(sq_sssd, 1.3)

require {
    type sssd_t;
    type sssd_var_lib_t;
    type tmp_t;
    class lnk_file { read write create };
    class file { getattr read };
}

#============= sssd_t ==============
allow sssd_t sssd_var_lib_t:lnk_file { create read write };
allow sssd_t tmp_t:file { getattr read };


This of course could probably be shortened with macros.

Comment 2 Milos Malik 2012-06-19 02:39:51 EDT

Which version of selinux-policy packages is installed on your machine?

Comment 3 lance dillon 2012-06-19 07:49:58 EDT

selinux-policy-2.4.6-327.el5

Comment 4 lance dillon 2012-06-19 07:54:32 EDT

Just had an additional entry in audit.log, audit2allow reported this:

#============= sssd_t ==============
allow sssd_t tmp_t:file { read lock getattr unlink };

Please include the original AVCs that you were seeing as well.

Comment 6 lance dillon 2012-06-19 09:21:06 EDT

Upon further investigation and discussion on #sssd, it appears that selinux-policy may have been updated after sssd was started, so the policy wasn't applied yet.  I'm not encountering the problem currently, can't seem to reproduce (I've tried on a couple of different systems), so I'm going to close this, if I can.
