strchan 0.9.2.4 Released

Description: OpenSS7 What's New.

Approved for Immediate Release

Oct 31, 2008
OpenSS7 today announced Release 0.9.2.4 of the STREAMS Channels (CHAN) strchan package.

(Edmonton, Alberta -- Oct 31, 2008)   OpenSS7 today announced Release 0.9.2.4 of the STREAMS Channels (CHAN) strchan package. The OpenSS7 STREAMS Channels package provides STREAMS modules and drivers, libraries, programs, init scripts, and daemons that implement the OpenSS7 STREAMS isochronous channels for the purpose of implementing data transmission links, or for carrying voice or other media, such as channelization of T1 carrier facilities, or ATM AAL3. This package also includes pseudo-isochronous channels such as those provided by RTP.

Included are hardware device drivers and pseudo-device drivers that provide implementations of specific channels. A pseudo-device driver is planned to link into the Linux OSS (Open Sound System) and ALS (Advanced Linux Sound). Specific E1/T1 cards such as the V401P are supported by this package.

This package also supports data channel protocols for data communication over isochronous channels such as HDLC and SS7 DAEDR/DAEDT/AERM/SUERM. Upper layer link protocols, such as LAPB, LAPF, LAPM and LLC are supported by separate packages. These modules are provided here because they work directly over an isochronous channel and are therefore designed to work with them. These data links provide support for the OpenSS7 STREAMS X.25 and Frame Relay, OpenSS7 STREAMS ISO/OSI as well as the OpenSS7 STREAMS ISDN Stacks and OpenSS7 STREAMS SS7 Stack packages.

Note that no component in this package can be supported by LiS: LiS is simply too slow to allow these drivers to achieve any degree of efficiency necessary for proper operation.

This is the fourth separate release from The OpenSS7 Project of the OpenSS7 STREAMS Channels package. The package provides components that were previously part of the strss7 package. This package contains all the necessary manual pages and other documentation. The package is packaged as an OpenSS7 style autoconf tarball.

This is the fourth pre-alpha release for Linux Fast-STREAMS and is an optional part of the OpenSS7 Master Package (as of openss7-0.9.2.D).

This release is a maintenance release providing support for recent distributions and tool chains.

This is a public pre-alpha release of the package. Please see README-alpha in the release or Maturity, in the manual.

This package is currently incomplete. It is being released as a reference point for the community. See TODO in the release or Schedule in the manual, for more information about the release schedule. If you are interested in completion of this package, contact info@openss7.com.

Major features since the last public release are as follows:

• Minor documentation corrections.
• Kernel module license made explicit GPL v2. And then changed back to GPL.
• License upgrade to AGPL Version 3.
• Modifications to build under Fedora 2.6.22.5-49 kernel. These changes also support 2.6.22.9-91.fc7 kernel.
• Ability to strap out major documentation build and installation primarily for embedded targets.
• Improvements to common build process for embedded and cross-compile targets.
• Modifications to build under Fedora 2.6.25-45.fc9 and 2.6.26.5-45.fc9 kernels.
• Updated tool chain to m4-1.4.12, autoconf-2.63 and texinfo-4.13.
• Conversion of RPM spec files to common approach for major subpackages.
• Updated references database for manual pages and roff(1) documents.
• Build system now builds yum(8) repositories for RPMs and apt-get(8) repositories for DEBs. Installation documentation has been updated to include details of repository install sourcesref.
• Added MODULE_VERSION to all modules and drivers.
• Added Open Media Gatway project document and updated documentation.
• Added mx-pmod and ch-pmod STREAMS modules and manual pages (ch-pmod(4) and mx-pmod(4)). These STREAMS modules provide the CH and MX interfaces to a STREAMS-based pipe acting as a channel or multiplex connection for testing and complex interconnection of channels and multiplexes.
• 64-bit corrections to the CHI header file, sys/chi.h.
• Fix for freezestr() and unfreezestr() on 2.4 kernels.

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 Affero General Public License (AGPL) Version 3. 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 strchan package page for tarballs, SRPMs, DSCs, and binary RPMs and DEBs.
