This *untested* patch adds a new permission managing file system.
Furthermore, it adds two modules, which make use of this file system.

One module allows granting capabilities based on user-/groupid. The
second module allows to grant access to lower numbered ports based on
user-/groupid, too.

Changes:
- updated to 2.6.38

This patch is available at:

That last sentence is handled (in theory) by "select NET_HOOKS", right?

But NET_HOOKS depends on INET && EXPERIMENTAL, so this config should not
select NET_HOOKS unless INET && EXPERIMENTAL are enabled also.
