Subjectproposed patches for 2.3.11
Hi Linus,

Following are two patches against clean 2.3.10 which I'd like to submit
for 2.3.near_future.

The first is a forward port (re-diff :) of the capability bounding set
patch which is in Alan's proposed 2.2.11pre2. This goes some way towards
restoring 2.0's securelevel functionality.

Hopefully, it's pretty uncontroversial.

The second requires CAP_SYS_RAWIO to open /dev/mem, /dev/kmem, /dev/port
and /proc/kcore. (Something similar should also be done to Alan's
dmaram.c.)

This one may be slightly more contentious, as 2.0 securelevel restricted
only _write_ to mem and kmem. I intend to submit something like this for
2.2, but I think that 2.3 and onwards could and should be more aggressive
on issues like this.

Comments?

Matthew.
