LiS 2.18.6 Released

Description: OpenSS7 Old News.

Approved for Immediate Release

Jun 24, 2007
OpenSS7 today announced Release 2.18.6 of the Linux STREAMS LiS package.

(Edmonton, Alberta -- Jun 24, 2007)   OpenSS7 today announced Release 2.18.6 of the Linux STREAMS LiS package. The OpenSS7 Linux STREAMS (LiS) package is an OpenSS7 modified version of the LiS-2.18 package formerly from GCOM, and formerly maintained by David Grothe.

Note: The original LiS package from GCOM is no longer actively maintained by either GCOM or the OpenSS7 Project: use the OpenSS7 Linux Fast-STREAMS package instead.

The following are claims made by its authors and original maintainer:

The OpenSS7 Modified Linux STREAMS (LiS) package is as STREAMS framework that is compatible with SVR 4 STREAMS. It has lots of debugging features not found in other STREAMS packages. Good to do networking and other things. It allows for installation of binary drivers.

Linux STREAMS (LiS) aims to provide SVR 4 compatible STREAMS implementation for Linux and claims to have special debugging facilities; however, the package suffers from the major failings that it is:

• no longer maintained;
• full of bugs;
• incompatible with POSIX;
• implements SVR 4 STREAMS rather than the more popular SVR 4.2 MP/ES STREAMS;
• portions dubiously licensed under the LGPL;
• unsuitable for mainline adoption;
• adapts poorly to production kernels;
• many SMP races and lockups;
• broken 32-bit over 64-bit compatibility;
• no strlog(9) STREAMS logger;

This is an internal release of LiS. It is only available for download by subscribers and sponsors of the OpenSS7 Project. There are too many packages that cannot build against LiS due to its implementation deficiencies.

Do not use this release (even if you are a subscriber or sponsor). Port to Linux Fast-STREAMS. Do not report bugs on this release. The OpenSS7 Project no longer actively maintains LiS.

Major changes for release LiS-2.18.6:

• Performance of LiS has now been shown to be dismally poor: Linux Fast-STREAMS is running 25 times faster in 1/10th the footprint.
• Support build on openSUSE 10.2.
• Support build on Fedora 7 with 2.6.21 kernel.
• Support build on CentOS 5.0 (RHEL5).
• Support build on Ubuntu 7.04.
• Updated to gettext 0.16.1.
• Changes to support build on 2.6.20-1.2307.fc5 and 2.6.20-1.2933.fc6 kernel.
• Supports build on Fedora Core 6.
• Support for recent distributions and tool chains.

This is an unstable internal alpha release of the package. Please see README-alpha in the release for more information. Do not report bugs on this package.

A large number of additional tests cases were found to fail on x86_64 and SMP architectures making the LiS packages largely unusable, especially on 64-bit or SMP kernels.

Deprecated and unmaintained. Download the latest streams package version instead.

As with other OpenSS7 releases, this release configures, compiles, installs and builds RPMs and DEBs for a wide range of Linux 2.4 and 2.6 RPM- and DPKG-based distributions, and can be used on production kernels without patching or recompiling the kernel.

This package is publicly released under the GNU Public License Version 2. The release is available as an autoconf tarball, SRPM, DSC, and set of binary RPMs and DEBs. See the downloads page for the autoconf tarballs, SRPMs and DSCs. See the LiS package page for tarballs, SRPMs, DSCs, and binary RPMs and DEBs.

See ChangeLog and NEWS in the release for more information. Also, see the LiS.pdf manual in the release (also in html here).
