Description Matěj Cepl 2010-12-23 07:49:14 UTC
SELinux is preventing /sbin/setfiles from 'associate' accesses on the filesystem /sys.

*****  Plugin filesystem_associate (99.5 confidence) suggests  ***************

If you believe setfiles should be allowed to create sys files
Then you need to use a different command. You are not allowed to preserve the SELinux context on the target file system.
Do
use a command like "cp -p" to preserve all permissions except SELinux context.

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that setfiles should be allowed associate access on the sys filesystem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep /sbin/setfiles /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Matej what were you doing to cause this?

Comment 2 Matěj Cepl 2010-12-23 19:26:45 UTC
just clicked on "Restore context" in sealert troubleshoot window. But maybe it was caused by very much messed up (post mock) labels on my disk.
