[PATCH 0/8] SECURITY ISSUE with connector

[Philipp Reisner <philipp.reisner@linbit.com>]

Affected: All code that uses connector, in kernel and out of mainline

The connector, as it is today, does not allow the in kernel receiving
parts to do any checks on privileges of a message's sender.

I know, there are not many out there that like connector, but as
long as it is in the kernel, we have to fix the security issues it has!

Please either drop connector, or someone who feels a bit responsible
and has our beloved dictator's blessing, PLEASE PLEASE PLEASE take 
this into your tree, and send the pull request to Linus.

Patches 1 to 4 are already Acked-by Evgeny, the connector's maintainer.
Patches 5 to 7 are the obvious fixes to the connector user's code.

For convenience these patches are also available as git tree:
git://git.drbd.org/linux-2.6-drbd.git connector-fix
