NGPT 1.9.3 RELEASED; NEW KERNEL PATCH ENHANCES FUNCTIONALITY

NGPT 1.9.3 RELEASED; NEW KERNEL PATCH ENHANCES FUNCTIONALITY

NGPT Release 1.9.3 is an "unstable" release of the NGPT 2.0 development
tree. This release is fully suitable as a replacement for LinuxThreads by
either a single user or group or and entire distribution. The NGPT team
plans to do releases almost weekly of this 1.9.x tree until the release of
NGPT 2.0.

In this release, we've concentrated on continuing to stabilize the code in
preparation for the 2.0 release. This code is still "unstable" and could
cause some problems although, we haven't seen anything major to worry
about.

The binary RPMs supplied with this release are based on and built for use
with a 2.4.19pre10 or better kernel that has the new "officially"
sanctioned support for NGPT. In addition it is necessary for you to apply
the new patch-futex-2.4.19 patch, included in this release. This patch is
based on new functionality already provided in the 2.5 kernel that will
eventually be backported to the 2.4 kernel and support. There is also a
patch, patch-kngpt-2.4.18, that is designed to be installed over a standard
2.4.18 kernel from kernel.org. NGPT takes advantage of the functionality
provided by these patches to efficiently handle mutexes, both shared and
non-shared. This patch is **ABSOLUTELY REQUIRED**. NGPT will not function
without it. The installation instructions have changed a bit as well since
1.2.2 and you should check the INSTALL file for the updated instructions.

You can build the library from source by downloading the source tarball or
source rpm and consulting the INSTALL file.

This release is also accompanied by another kernel patch that implements
POSIX credential handling for threading. This is an early release of the
patch and is being distributed so that we can get feedback prior to
submitting the patch for inclusion in the Linux kernel. Please report any
problems via the NGPT developer mailing list.

If you are running with a 2.5.x experimental kernel, it's best that run
with 2.5.17 or higher since it will already have the required changes for
NGPT. You will also have to rebuild NGPT from either the source tarball or
rpm.

As an UNSTABLE RELEASE, this release is not suitable for use in a
production environment, however, it should be noted that we have done
fairly extensive testing and you should find this release relatively free
of problems. If you encounter any problems with this release please post
them to the NGPT website and the development team will address them.
