:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that udevd should be allowed sendto access on the multipath_event unix_dgram_socket 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 udevd /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Mads Kiilerich 2011-07-22 15:31:50 UTC
This happened while building a live cd (installing packages in chroot) ... but it doesn't seem related ...

Comment 2 Daniel Walsh 2011-07-22 20:34:24 UTC
lvm people,  Is this something knew udev communicating with lvm over @/org/kernel/dm/multipath_event

Comment 3 Ben Marzinski 2011-07-22 21:37:10 UTC
Multipathd has been getting events from udev over @/org/kernel/dm/multipath_event since the start of RHEL6.

Comment 4 Daniel Walsh 2011-07-25 15:59:15 UTC
We usually run udev_t unconfined in RHEL6, which is why no one saw it.

Fixed in selinux-policy-3.10.0-10.fc16

Miroslav please back port this to RHEL6.
