1131501 – Mislabeled file '/var/lock/subsys/rtas_errd' found

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 Martin Žember 2014-08-19 12:45:52 UTC

Description of problem:
Mislabeled regular file '/var/lock/subsys/rtas_errd' found. Labeled as 'system_u:object_r:var_lock_t:s0', should be 'system_u:object_r:rtas_errd_var_lock_t:s0'.

Version-Release number of selected component (if applicable):
librtas-1.3.10-1.el6
RHEL-6.6-20140731.1

How reproducible:
Always

Steps to Reproduce:
1. Install all packages on a RHEL-6.6 system, RHEL-6.6-20140731.1
2. # matchpathcon /var/lock/subsys/rtas_errd
/var/lock/subsys/rtas_errd	system_u:object_r:rtas_errd_var_lock_t:s0
3. # restorecon -v /var/lock/subsys/*
restorecon reset /var/lock/subsys/rtas_errd context system_u:object_r:var_lock_t:s0->system_u:object_r:rtas_errd_var_lock_t:s0

Actual results:
restorecon reset /var/lock/subsys/rtas_errd context system_u:object_r:var_lock_t:s0->system_u:object_r:rtas_errd_var_lock_t:s0

Expected results:
Already rtas_errd_var_lock_t

At least that is how it looks like after:
# restorecon /boot/etc/yaboot.conf

Comment 1 Martin Žember 2014-08-19 12:50:18 UTC

Additional info:
# ls -Zl /var/lock/subsys
-rw-r--r--. 1 system_u:object_r:var_lock_t:s0  root root 0 Aug 18 12:57 abrt-ccpp
-rw-r--r--. 1 system_u:object_r:var_lock_t:s0  root root 0 Aug 18 12:57 abrtd

(...too long)

2 files have a more specific context, e.g. rtas_errd_var_lock_t, the rest (29 files) have var_lock_t. Don't the other files deserve a more specific context, too? I am trying to find a way to speed up the process as there are many of them.

Comment 3 Martin Žember 2014-08-19 15:49:43 UTC

There are no transition rules if a initrc_t-labeled process creates the file:
# sesearch -s initrc_t -t var_lock_t -c file -T

The daemon itself does not create it:
# sesearch -s rtas_errd_t -t var_lock_t -c file -T
Found 1 semantic te rules:
   type_transition rtas_errd_t var_lock_t : file rtas_errd_var_lock_t; 

It is /etc/init.d/rtas_errd who creates it by 'touch'.

Solution: either run 'restorecon' from within /etc/init.d/rtas_errd or create the lock file in the daemon.
