1.4.2 for kernel 2.6.31 released

-----BEGIN PGP SIGNED MESSAGE-----

Hello everyone,

RSBAC 1.4.2 has been released for kernel 2.6.31.

You can download it from the usual locations, at http://www.rsbac.org
or your favorite mirror.

Here is a summary of the 1.4.2 release announcement:

With RSBAC 1.4.2, we expect a significant
speedup and even better SMP scalability from the new RCU based list
locking.

There will be no more releases for 2.4 kernels, because new features
like RCU
require 2.6. Still, 1.4.1 for 2.4.37 is very stable and has no known
bugs.
Please keep using 1.4.1 for 2.4 like we do. The svn trunk for 2.4 will
stay
maintained for a while.

Most Important changes since 1.4.0 (somehow we skipped the 1.4.1
announcement):

  * Change generic lists to use RCU instead of rw spinlocks

  * New SCD target videomem on x86 arch to distinguish between video
and other
kernel memory (SCD kmem) access

  * New config option RSBAC_ENFORCE_CLOSE to really deny close, if decided

  * Check protocol in NETLINK network templates when matching

  * Upgrade to 2.6.29.x, tons of kernel internal API changes again a usual

  *  Many small bugfixes

Upgrading from 1.3 or 1.4.x is easy: Compile, install and boot. Some
extra
checks might require minor adjustments, though.
