Thanks for the response. See stuff below. Pavel Kankovsky wrote:

Large enterprise customers typically don't give out sudo access to all admins. So, they would like a way to designate certain scripts/modules as "blessed", and allow admins/developers/etc. without root access to run those "blessed" scripts/modules.The easiest way to designate a certain script as "blessed" (and quite difficult to goof it up) is to let a trusted user take the source of the script, check it, make a kernel module, and install it into a designated directory on the target system (or systems), perhaps under "/lib/modules/$version".
That's my current thinking. Seems easier from a user's point of view and less fragile from a security point of view.
If you are afraid of allowing "untrusted admins" run "sudo modprobe the_probe" (but not afraid of allowing to run your own setuid root program) you can create something like "sustaprun" that will make it possible to load blessed modules (from the designated directory) only.
That's also my current thinking. I'm trying to prototype this now. -- David Smith dsmith@xxxxxxxxxx Red Hat http://www.redhat.com 256.217.0141 (direct) 256.837.0057 (fax) -- Fedora-security-list mailing list Fedora-security-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-security-list
