Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

Comment 5 Milos Malik 2011-02-25 13:01:58 UTC
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.

Comment 10 Miroslav Grepl 2011-03-01 13:56:54 UTC
Fixed in selinux-policy-3.7.19-74.el6
