Description Milos Malik 2011-02-25 12:15:10 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-72.el6.noarch
selinux-policy-targeted-3.7.19-72.el6.noarch
selinux-policy-mls-3.7.19-72.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. install MLS policy on a RHEL-6 machine
2. modify /etc/selinux/config so that the machine will start up with MLS policy in permissive mode
3. modify /boot/grub/grub.conf so that the machine will start up into single-user mode
4. run 'touch /.autorelabel'
5. run 'reboot'
6. log in as root via console
7. run 'reboot' and search for 'type=' messages in the console
  
Actual results:
type=1400 audit(1298633324.629:4): avc:  denied  { setfscreate } for  pid=682 comm="lvm" scontext=system_u:system_r:lvm_t:s0-s15:c0.c1023 tcontext=system_u:system_r:lvm_t:s0-s15:c0.c1023 tclass=process
type=1400 audit(1298633324.687:5): avc:  denied  { setfscreate } for  pid=682 comm="lvm" scontext=system_u:system_r:lvm_t:s0-s15:c0.c1023 tcontext=system_u:system_r:lvm_t:s0-s15:c0.c1023 tclass=process

Expected results:
no AVCs

Easy to reproduce with following tools:
 * lvdisplay
 * pvdisplay
 * vgdisplay
Comment 6 Daniel Walsh 2011-02-25 15:28:11 UTC 
Looks like we need f15 lvm policy back ported to RHEL6.

How did rhel6 get so old so fast.
Comment 7 Miroslav Grepl 2011-02-25 15:34:56 UTC 
I am seeing only one difference

+kernel_get_sysvipc_info(lvm_t)
Comment 8 Miroslav Grepl 2011-02-25 15:37:59 UTC 
Oops, you are right. Bad diff.
Comment 9 Miroslav Grepl 2011-02-25 15:39:48 UTC

> Oops, you are right. Bad diff.

It was diff with F14 policy.
