613019 – SELinux is preventing /usr/bin/rsync "mac_admin" access .

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 David Kovalsky 2010-07-09 14:33:29 UTC

Summary:

SELinux is preventing /usr/bin/rsync "mac_admin" access .

Detailed Description:

SELinux denied access requested by rsync. It is not expected that this access is
required by rsync and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 David Kovalsky 2010-07-09 14:35:35 UTC

Hundreds of these messages appeared while I was running

`rsync -avHEX --progress ${SOME_EXCLUDES} root@host: /mnt/tmp/'

/mnt/tmp/ contains an incomplete sync of F12 root partition.

Comment 3 Daniel Walsh 2010-07-12 15:23:36 UTC

mac_admin means you are trying to put down selinux labels that the kernel does not understand.  This is expected behaviour.  If you are going to rsync between two systems and request the labels be maintained, then you have to make sure the both machines understand the labels or they will be denied.  Some thing would happen if you tar'd up a bunch of files with labels and tried to install them on an SELinux machine that did not understand the labels.
