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 Ondrej Moriš 2018-01-16 10:07:06 UTC 
Description of problem:

Selinux policy denies audisp-remote (audispd plugin for remote logging) to write to its queue file /var/spool/audit/remote.log:

time->Tue Jan 16 10:10:10 2018
node=REMOTE_LOGGING_CLIENT type=PROCTITLE msg=audit(1516093810.889:5569629): proctitle="/sbin/audisp-remote"

node=REMOTE_LOGGING_CLIENT type=AVC msg=audit(1516093810.889:5569629): avc:  denied  { write } for  pid=22634 comm="audisp-remote" name="remote.log" dev="dm-4" ino=4230169 scontext=system_u:system_r:audisp_remote_t:s15:c0.c1023 tcontext=staff_u:object_r:audit_spool_t:s0 tclass=file

Tool audit2allow suggest to add the following rule:

allow audisp_remote_t audit_spool_t:file write;

Loading a module containing aforementioned rule resolves the issue. Without it, remote logging with forwarding does not work. 

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

audit-2.8.1-3.el7
kernel-3.10.0-823.el7
selinux-policy-3.13.1-183.el7
selinux-policy-mls-3.13.1-183.el7

How reproducible:

100%

Steps to Reproduce:

1. Setup audit-remote logging using client forwarding mode.
2. Start auditd.

Actual results:

From journalctl:

audisp-remote[22659]: Error initializing audit record queue: Permission denied
audisp-remote[22659]: Connected to A.B.C.D

And AVC mentioned in description.

Expected results:

audisp-remote[25338]: Audisp-remote started with queue_size: 1
audisp-remote[25338]: Connected to A.B.C.D

Additional info:

This problem was discovered on MLS system but it should be reproducible on a system with targeted policy.
