Description Dan Mashal 2012-09-25 00:29:56 EDT
I am receiving this error in Fedora 17:

SELinux is preventing /usr/lib64/dbus-1/dbus-daemon-launch-helper from execute access on the file /usr/local/libexec/msd-datetime-mechanism.

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore dbus-daemon-launch-helper trying to execute access the msd-datetime-mechanism file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
# grep /usr/lib64/dbus-1/dbus-daemon-launch-helper /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that dbus-daemon-launch-helper should be allowed execute access on the msd-datetime-mechanism file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep dbus-daemon-lau /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-09-25 06:45:27 EDT
could you try to execute

# chcon -t gnomeclock_exec_t PATHTO/msd-datetime-mechanism

and see if it works. Thank you.
Comment 2 Dan Mashal 2012-09-25 11:44:17 EDT

This is from MATE Desktop.

Do you think we could work together some time on getting a policy setup for MATE (formerly known as Gnome 2)?
Comment 3 Daniel Walsh 2012-09-25 15:24:47 EDT
Dan why is MATE installing content into /usr/local?
Comment 4 Dan Mashal 2012-09-25 15:35:27 EDT
Good question Daniel,

I assume that's a bad place?

If so, I'll fix that.
Comment 5 Daniel Walsh 2012-09-25 16:25:26 EDT
Yes you should just install in /usr/libexec or something on the system.  Packagers are not supposed to use /usr/local.
Comment 6 Dan Mashal 2012-10-07 07:04:51 EDT
Thanks Dan.
