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the product is no longer active in Red Hat Bugzilla.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 of problem:
Setroubleshoot plugins are searching for non existent types which causes the plugins not to be applied where expected (insmod/depmod/update_modules, file_t, semange_read_lock_t). Some of the types are refered to in "problem decription" (e.g. dhclient_t).
Version-Release number of selected component (if applicable):
Setroubleshoot-plugins-3.3.11-2
How reproducible:
Cause an AVC with one of the following types:
kmod_exec_t, kmod_tmp_t, semanage_read_lock_t
For each of them there is a setroubleshoot plugin which should show suggestions, but doesn't.
Steps to Reproduce:
# cat avc
type=AVC msg=audit(1587399662.357:495): avc: denied { write } for pid=33024 comm="runcon" dev="sda3" ino=6832090 scontext=system_u:system_r:audisp_t:s0-s0:c0.c1023 tcontext=system_u:object_r:kmod_exec_t:s0 tclass=file permissive=0
# sealert -a avc
Actual results:
Only the catchall plugin lists it's suggestion.
Expected results:
SELinux is preventing runcon from write access on the file labeled kmod_exec_t.
***** Plugin kernel_modules (91.4 confidence) suggests ********************
If you do not think runcon should try write access on Unknown.
Then you may be under attack by a hacker, since confined applications should not need this access.
Do
contact your security administrator and report this issue.
