Subject: Re: [PATCH 1/1] security: introduce fs caps

The patch applies cleanly , compiles and runs smoothly against 2.6.18.1.

I'm running slackware-current with a 2.6.18.1 kernel on an ext3
filesystem.

Background why I use the patch:
With 2.6.18 to create a tuntap interface CAP_NET_ADMIN is required.
Qemu uses tuntap to create a tap interface as a virtual net interface.
Instead now running qemu with root privileges to give it the right
to create a tap interface, i granted qemu with the help of the patch and
Kaigai Kohei's userspace tools the cap-net_admin capability. So qemu
runs again without root privilege but has now the right to create the
tap interface.

Thanks for the patch. It reduces my the need of suid-bit progs.
It should be given a spin in -mm.

I will document my experiences on http://www.friedhoff.org/fscaps.html
