Description Samster 2008-11-10 11:20:29 EST
Description of problem:
SELinux denied access requested by tmpwatch. It is not expected that this access is required by tmpwatch 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 AccessSometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for ./kdecache-jim, restorecon -v './kdecache-jim' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.

Comment 1 Daniel Walsh 2008-11-10 14:52:46 EST
What directory do you have labeled samba_share_t?
Comment 2 Samster 2008-11-10 15:27:21 EST
/tmp/kde-jim/ksycoca -> /var/tmp/kdecache-jim/ksycoca
ksycoca: symbolic link to `/var/tmp/kdecache-jim/ksycoca'

kdecache-jim  within /var/tmp is labeled samba_share_t


Within the kdecache-jim directory are two other files labeled samba_share_t:

drwx------  jim jim unconfined_u:object_r:samba_share_t:s0 help
-rw-rw-r--  jim jim unconfined_u:object_r:samba_share_t:s0 ksycoca

The 'help' directory is empty.
Comment 3 Daniel Walsh 2008-11-10 16:35:38 EST
Well then the question is do you want to allow tmpreaper to delete these files, if yes, you can update policy to allow it.

# grep samba_share_t /var/log/audit/audit.log | audit2allow -M mytmpreaper
# semodule -i mytmpreaper.pp

Or just delete the files/directory yourself.
