Please note, however, that there are different licensing terms for the manual pages and some of the documentation (derived from OpenGroup1 publications and other sources). Consult the permission notices contained in the documentation for more information.

This manual is released under the FDL (see GNU Free Documentation License) with no invariant sections, no front-cover texts and no back-cover texts.


Abstract

This manual provides a Installation and Reference Manual for OpenSS7.

Objective

The objective of this manual is to provide a guide for the STREAMS programmer when developing STREAMS modules, drivers and application programs for OpenSS7.

This guide provides information to developers on the use of the STREAMS mechanism at user and kernel levels.

STREAMS was incorporated in UNIX System V Release 3 to augment the character input/output (I/O) mechanism and to support development of communication services.

STREAMS provides developers with integral functions, a set of utility routines, and facilities that expedite software design and implementation.

Intent

The intent of this manual is to act as an introductory guide to the STREAMS programmer. It is intended to be read alone and is not intended to replace or supplement the OpenSS7 manual pages. For a reference for writing code, the manual pages (see STREAMS(9)) provide a better reference to the programmer. Although this describes the features of the OpenSS7 package, OpenSS7 Corporation is under no obligation to provide any software, system or feature listed herein.

Audience

This manual is intended for a highly technical audience. The reader should already be familiar with Linux kernel programming, the Linux file system, character devices, driver input and output, interrupts, software interrupt handling, scheduling, process contexts, multiprocessor locks, etc.

The guide is intended for network and systems programmers, who use the STREAMS mechanism at user and kernel levels for Linux and UNIX system communication services.

Readers of the guide are expected to possess prior knowledge of the Linux and UNIX system, programming, networking, and data communication.

Agencies

It would be difficult for the OpenSS7 Project to attain the conformance and certifications that it has without the free availability of specifications documents and standards from standards bodies and industry associations. In particular, the following:

3GPP (Third Generation Partnership Project)
ATM Forum
EIA/TIA (Electronic Industries Alliance)
ETSI (European Telecommunications Standards Institute)
ICAO (International Civil Aviation Organization)
IEEE (Institute of Electrical and Electronic Engineers)
IETF (The Internet Engineering Task Force)
ISO (International Organization for Standardization)
ITU (International Telecommunications Union)
Mulutiservices Forum
The Open Group

Of these, ICAO, ISO, IEEE and EIA have made at least some documents publicly available. ANSI is notably missing from the list: at one time draft documents were available from ANSI (ATIS), but that was curtailed some years ago. Telecordia does not release any standards publicly. Hopefully these organizations will see the light and realize, as the others have, that to remain current as a standards organization in today’s digital economy requires providing individuals with free access to documents.

Repository Installation

The simplest way of installing the package is to use the OpenSS7 repomd or apt repositories instead of attempting to build from tarball. When you already have a the repository set up, the package can be udpated simply with (one of):

Fedora:   $> sudo yum update openss7
CentOS:   $> sudo yum update openss7
RHEL:     $> sudo yum update openss7
OpenSUSE: $> sudo zypper update openss7
SLES:     $> sudo zypper update openss7
Mageia:   $> sudo uprmi openss7
Mandriva: $> sudo urpmi openss7
MES:      $> sudo urpmi openss7
Ubuntu:   $> sudo aptitude install openss7
Debian:   $> sudo aptitude install openss7

If you have not yet set up an installation source for the OpenSS7 repositories, one of the following commands will establish repository access for RPM-based systems:

          $> REPO=http://www.openss7.org/repo/rpms
Fedora:   $> SUBDIR=fedora/15/$(uname -m)/RPMS/noarch

MES:      $> SUBDIR=mes/5.2/$(uname -m)/RPMS/noarch
          $> sudo rpm -Uhv $REPO/$SUBDIR/openss7-repo.noarch.rpm

For DPKG-based systems, one of the following command sequences will establish repository access for DPKG-based systems:

          $> REPO=http://www.openss7.org/repo/debs/
Debian:   $> SUBDIR=debian/squeeze/$(dpkg-architecture -a -qDEB_HOST_ARCH)/main
Ubuntu:   $> SUBDIR=ubuntu/10.04/$(dpkg-architecture -a -qDEB_HOST_ARCH)/main
          $> wget $REPO/$SUBDIR/openss7-repo_all.deb
          $> dpkg -i -D010077 openss7-repo_all.deb

For zypper(8) based systems it may be first necessary to perform:

OpenSUSE: $> sudo rpm --import https://www.openss7.org/pubkey.asc

Debian:   $> sudo aptitude remove openss7 openss7-repo
Ubuntu:   $> sudo aptitude remove openss7 openss7-repo

Build Prerequisites

When building from source RPM or DSC, the prerequisites for building must be met. Most RPM or DEB build prerequisites are automatic; however, some prerequisites must still be met manually. When building from tarball, most prerequisites must be met manually. The configure script will inform you of most missing prerequisites and the actions that must be performed to meet those prerequisites.

Prerequisites for building OpenSS7 package are as follows:

  1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4, 2.6 or 3.x kernel and the appropriate tool chain for compiling out-of-tree kernel modules. Most recent Linux distributions are usable out of the box, but some development packages must be installed. For more information, see Compatibility.
    - A fairly LSB compliant GNU/Linux distribution.10
    - Linux 2.4 kernel (2.4.10 - 2.4.27),
    - Linux 2.6 kernel (2.6.3 - 2.6.39), or
    - Linux 3.x kernel (3.0 - 3.14);
    - glibc2 or better.
    - GNU groff (for man pages).11
    - GNU texinfo (for info files).
    - GNU bison and flex (for config programs).
    - net-snmp (for SNMP agents).12
    - GNU gcj and classpath (for Java modules).
    - swig (for Java, Tcl, Perl and Ruby interfaces).

The following will meet most additional prerequisites for a CentOS/RHEL 5.5 build host:

#> yum install bzip2 chkconfig coreutils createrepo doxygen \
        gcc-java ghostscript gjdoc glibc gnupg gnuplot \
        groff gzip ImageMagick kernel-devel latex2html \
        libgcj lsof module-init-tools rpm rpm-build tetex \
        tetex-dvips tetex-latex transfig xz xz-lzma-compat \
        zip

The following will meet most additional prerequisites for a CentOS/RHEL 6.0 build host:

#> yum install bzip2 chkconfig coreutils createrepo doxygen \
	gcc-java ghostscript glibc gnuplot groff gzip ImageMagick \
	java-1.6.0-openjdk-devel java-1.6.0-openjdk-javadoc \
	kabi-whitelists kernel kernel-devel latex2html libgcj \
	libgcj-devel lsof module-init-tools net-snmp-devel \
	perl-devel rpm rpm-build tcl-devel texlive texlive-dvips \
	texlive-latex texlive-utils transfig xz zip

The following will meet most additional prerequisites for a SuSE Linux Enterprise 11 build host:

#> zypper install aaa_base bzip2 coreutils createrepo doxygen \
        fastjar gcc43-gij gcc-java ghostscript-library gjdoc \
        glibc gnuplot gpg2 groff gzip ImageMagick inst-source-utils \
        kernel-default-devel latex2html lsof module-init-tools \
        rpm texlive texlive-latex transfig zip

The following will meet most additional prerequisites for a Debian 6.0 build host:

#> apt-get install apt-utils bzip2 coreutils createrepo doxygen \
        dpkg dpkg-dev fastjar gcj-jdk gcj-jre-headless ghostscript \
        gnupg gnuplot-nox gnuplot-x11 groff groff-base gzip \
        imagemagick insserv latex2html libc-bin lsof lzma \
        module-init-tools rpm texlive-binaries texlive-font-utils \
        texlive-latex-base transfig xz-utils zip

The package builds and installs kernel modules. When configuring and building the package, it is necessary to have the kernel development package installed. For the following distributions, use the following commands:

Ubuntu:  $> apt-get install linux-headers
Debian:  $> apt-get install kernel-headers
Fedora:  $> yum install kernel-devel
CentOS:  $> yum install kernel-devel

You also need the same version of gcc(1) compiler with which the kernel was built. If it is not the default, add ‘CC=kgcc’ on the line after ‘./configure’, for example:

$> ../openss7-1.1.7.20141001/configure CC='gcc-3.4'

The package builds and installs SNMP agents. When configuring and building the package, it is necessary to have the net-snmp development packages installed. For the following distributions, use the following commands:

Ubuntu:  $> apt-get install libsnmp libsnmp-perl snmp snmpd \
                lm-sensors libsnmp-dev libsnmp9-dev libsensors-dev
Debian:  $> apt-get install libsnmp libsnmp-perl snmp snmpd \
                lm-sensors libsnmp-dev libsnmp9-dev libsensors-dev
Fedora:  $> yum install net-snmp net-snmp-perl net-snmp-utils \

Brief Installation Instructions

The OpenSS7 package is available from the downloads area of The OpenSS7 Project website using a command such as:

$> wget http://www.openss7.org/tarballs/openss7-1.1.7.20141001.tar.xz

Unpack the tarball using a command such as:

$> tar -xJvf openss7-1.1.7.20141001.tar.xz

The tarball will unpack into the relative subdirectory named after the package name: openss7-1.1.7.20141001.

The package builds using the GNU autoconf utilities and the configure script. To build the package, we recommend using a separate build directory as follows:

$> mkdir build
$> cd build
$> ../openss7-1.1.7.20141001/configure

In general, the package configures and builds without adding any special options to the configure script. For general options to the configure script, see the GNU INSTALL file in the distribution:

$> less ../openss7-1.1.7.20141001/INSTALL

For specific options to the configure script, see the INSTALL-openss7 file in the distribution, or simply execute the configure script with the --help option like so:

$> ../openss7-1.1.7.20141001/configure --help

After configuring the package, the package can be compiled simply by issuing the ‘make’ command:

$> make V=0

Some specialized makefile targets exists, see the README-make file in the distribution or simply invoke the ‘help’ target like so:

$> make help | less

After successfully building the package, the package can be checked by invoking the ‘check’ make target like so:

$> make check

After successfully checking the package, the package can be installed by invoking the ‘install’ make target (as root) like so:

$> sudo make install

The info documentation is automatically installed; however, the text, html and pdf documentation must be installed separately like so:

$> sudo make install-txt
$> sudo make install-html
$> sudo make install-pdf

The test suites that ship with the package can be invoked after the package has been installed by invoking the ‘installcheck’ target. This target can either be invoked as root, or as a normal user, like so:

$> make installcheck

(Note: you must add the --enable-autotest flag to configure, above for the test suites to be invoked with ‘make installcheck’.)

The package can be cleanly removed (including installed documentation) by invoking the ‘uninstall’ target (as root):

$> sudo make uninstall

Then the build directory and tarball can be simply removed:

$> cd ..
$> rm -rf build
$> rm -rf openss7-1.1.7.20141001
$> rm -f openss7-1.1.7.20141001.tar.xz

2 Objectives


2.1 Background

STREAMS derives from Dennis Ritchie’s original paper,14 was incorporated into the UNIX® System V Release 3 operating system, replaced the terminal input-output subsystem, pipes and FIFOs in UNIX® System V Release 4, and was improved in the USL release of the UNIX® System V Release 4.2 operating system.

Today, STREAMS is a part of every major branded UNIX® variant, such as AIX®, HP-UX®, IRIX®, MacOT®, OSF/1®, Solaris®, SUPER-UX®, UnixWare®, UXP/V®, and including many UNIX-like operating systems and popular embedded RTOS, but with the notable exception of Berkeley System Distribution releases, variants and offshoots, and Linux.


2.2 What is STREAMS?

STREAMS is a flexible framework for communication between a user level process and a kernel resident driver. It encompasses a set of kernel system calls providing a user-kernel interface that is backward compatible with the traditional character device driver interface, as well as a set of STREAMS driver and module entry points forming a driver-kernel interface. STREAMS also provides a rich set of kernel utility functions for the development and implementation of kernel-resident drivers and modules. STREAMS prompted the specification of the DDI/DKI which is an architecture independent driver-kernel interface that provides a standardized set of kernel functions (beyond just STREAMS) for the development of device and software drivers.

STREAMS provides a reconfigurable full-duplex communications path between user level process and kernel resident driver, termed a Stream. Modules can be inserted in the path between the user and driver under user level control. Streams can be linked across multiplexers under user control to form complex (yet reconfigurable) topologies of user level processes and drivers.

Communication of control and data information along a Stream is accomplished by message passing. There is no direct function call interface between components of a Stream. A Stream exists within the STREAMS framework inside the kernel and extend from the user-kernel interface to the kernel driver interface. Each component of a Stream consists of a pair of queues used to pass messages in the upstream direction to the kernel-user interface; or downstream, the kernel-driver interface.

At the kernel-user end of the Stream is a component called the Stream head. As with all components of a Stream, the Stream head consists of a queue pair and a specialized set of procedures. The Stream head procedures are responsible for converting between the system call interface presented to users and the message passing mechanism within the Stream.

At the kernel-driver end of the Stream is the Stream end. The Stream end also contains a queue pair and a set of procedures. The Stream end (or simply driver) procedures are responsible for converting between the message passing mechanism within the Stream and the actions and events of a hardware (or pseudo-) device.

Intermediate components within the Stream are called Modules. Modules consist of a queue pair for passing messages upstream and downstream, as well as a set of procedures for processing messages. Modules can be pushed onto the module stack between the Stream head and Stream end using a set of standardized input-output control commands.

In support of topologies more complex than these simple linear segments, STREAMS also provides a specialized Stream end (driver) called a Multiplexing driver. A Multiplexing driver has the ability to open multiple Streams to its upper interface (multiplexer) as well as linking multiple Streams beneath its lower interface (multiplexer). Again, a standardized set of input-output controls provide the user with the ability to configure a Multiplexing driver.


2.3 Why STREAMS?

With the ability to open multiple Streams to a driver, push and pop modules to and from the module stack on a Stream, and to link any Stream under a multiplexing driver–all under user control using standardized input-output controls–allows STREAMS to configure complex topologies to form protocol stacks.

Almost all specialized standard telecommunications software developed since 1990 was developed to run on STREAMS. This is for several reasons:

  • Since 1990, STREAMS and the associated DDI/DKI has been, and remains, the only way to incorporate OEM protocol stacks into mainstream UNIX® system kernels.
  • The original UNIX System Laboratories (later X/Open then later the OpenGroup) support for ITU-T developed OSI protocols, makes STREAMS amenable to an open model for development for ITU-T protocols. (ITU-T, formerly CCITT, is the International Telecommunications Union – Telephone Sector responsible for international telephone standards, and original developers of the OSI model.)

As a result, there is a significant body of commercial software implementing telecommunications protocol stacks that was developed, tested, validated, conformance tested, field verified, to run on STREAMS: and is still running on STREAMS.

The cost of reimplementation, retesting, revalidation, redoing conformance testing, and field re-verification, would likely be prohibitive: after all, the point of Linux is reducing cost, is it not?


2.4 Why STREAMS for Linux?

The Linux kernel was not developed with STREAMS in mind. For TPI/IP networking, Linux originally followed in the footsteps of the BSD NET2 release. Currently, the implementation of TCP/IP in the Linux kernel has long departed from the classical BSD organization and exhibits characteristics unique to the GNU/Linux operating system. For character device and terminal input-output, Linux follows closely the SVR 3 pre-STREAMS approach to pipes, FIFOs and terminal subsystem. The terminal subsystem implementation, too, has become unique to GNU/Linux.

Therefore, from the perspective of TCP/IP networking and Terminal I/O, there would be little reason to provide STREAMS for Linux. That is, if it were not for the body of software supporting OSI and telecommunications protocols based solely on STREAMS, for which Linux has little or no support.

So, the answer to the question, "Why STREAMS for Linux?" is: so that a GNU/Linux platform can enjoy the same wealth of telecommunications and OSI protocol stacks otherwise only available to big-iron UNIX®. Without STREAMS, Linux is probably just another BSD, and probably not a very good one.


2.5 History of STREAMS for Linux

In 2000, The OpenSS7 Project abandoned using the Linux networking model for implementation of the Signalling System No. 7 protocol (primarily due to the lack of support for the full BSD networking model under Linux) and switched to using STREAMS as the basis for all future development. Over the span of the next 5 years, (and not surprisingly given the body of software), almost all Signalling System No. 7 products released on Linux used STREAMS.

In 2005, The OpenSS7 Project release (after two years of development) the streams-0.7a.4 package: a reimplementation of SVR 4.2 STREAMS with compatibility modules for all major UNIX® releases, called OpenSS7. OpenSS7 was intended as a POSIX/SUSv3 XSR conforming, high performance, production grade, implementation, suitable for mainline Linux adoption, and a better foundation on which to base SIGTRAN, VoIP, ISDN and SS7 protocol stacks developed under the The OpenSS7 Project, as well as a better foundation for porting commercial UNIX® OEM implementations to Linux. It is the openss7-1.1.7.20141001 package that contains the documentation you are reading now.


2.6 Why Fast?

In late 2003, The OpenSS7 Project decided to begin implementation of a production grade implementation of STREAMS, because of a number of shortcomings of other Linux STREAMS implementations:

  1. proprietary;
  2. unsuitable for mainline kernel adoption due to coding style or organization;
  3. poorly adapted to distribution production kernels;
  4. is unsuitable for packaging or repeatability;
  5. portability objective unsuitable for mainline kernel adoption;
  6. ports from the same baseline obfuscate the code;
  7. poor performance due to portability or coding style;
  8. code bloat or over sized memory footprint;
  9. redundant debug statements obscuring defects or obfuscating code;
  10. overuse of semaphores;
  11. contain serious races or not suitable for threaded applications;
  12. non-conformance to mainstream UNIX® implementations;
  13. non-conformance to POSIX or any release of the Single UNIX Specification;
  14. limited set of standard drivers or modules;
  15. limited set of diagnostic or administrative utilities;
  16. limited test programs;
  17. poorly documented.

The replacement, named OpenSS7, was to correct all of these difficulties, and, by the initial ‘streams-0.7a.4’ release, was:

  1. open source;
  2. completely Lindented and follows kernel coding practises;
  3. automatically adapts to production kernels with autoconf;
  4. packages itself into LSB compliant RPMs and DEBs;
  5. designed and implemented specifically for GNU/Linux;
  6. no ports considered;
  7. over twice the performance;
  8. less than one-eighth of the memory footprint;
  9. proper programming by assertion;
  10. proper use of lightweight spin locks;
  11. race free locking strategies and synchronization;
  12. compatible with all mainstream UNIX® implementations;
  13. conforms to POSIX/SUSv3 XSR;
  14. complete set of standard drivers and modules;
  15. complete set of diagnostic and administrative utilities;
  16. integrated set of conformance test suites;
  17. fully documented.

3.2 Drivers

The configuration of STREAMS drivers and modules is performed when compiling the OpenSS7 subsystem. The STREAMS subsystem, core drivers and modules are part of every OpenSS7 system.

The following lists the core drivers and modules, STREAMS kernel tunable parameters, and STREAMS configuration information:16

clone(4) (streams)

Clone device driver. This is a standard SVR 4.2 STREAMS driver. The clone(4) driver is a integral part of STREAMS and is used to create clone instances of a STREAMS driver.

See clone(4) for more information.

echo(4) (streams-echo)

Echo (loopback) device driver. This is a commonly implemented STREAMS driver. It is implemented by HP-UX® and OSF/1®. The echo(4) driver provides a simple FIFO-like device without full POSIX FIFO semantics. Its primary purpose is for the STREAMS Verification function, strvf(8), and the test-streams(8) validation test suite.

See echo(4) for more information.

fifo(4s) (streams-fifo)

FIFO (Named Pipe) device driver. This is a standard SVR 4.2 STREAMS driver. The fifo(4s) driver provides POSIX-compliant STREAMS-based FIFO device. Not all implementations of STREAMS provide STREAMS-based FIFOs: some implementations use the older SVR 3-style FIFOs that are not STREAMS-based. OpenSS7 provides STREAMS-based FIFOs with the fifo(4s) driver.

See fifo(4s) for more information.

log(4) (streams-log)

STREAMS log driver. This is a standard SVR 4.2 STREAMS driver. The log(4) driver provides a STREAMS capable logger in addition to the BSD logger present in Linux. The log(4) driver provides additional support for STREAMS modules and drivers using the strlog(9) kernel level utility. OpenSS7 also provides the strace(8), strerr(8) and strclean(8) administrative utility functions and startup scripts for controlling the log(4) driver.

See log(4) for more information.

loop(4) (streams-loop)

Loop device driver. This is a standard SVR 4.2 STREAMS driver. The loop driver is detailed in the UNIX System V Release 4 Programmer’s Manual – STREAMS. The loop(4) driver provides capabilities used primarily for validation test programs (see test-streams(8)) as well as serving as an example driver.

See loop(4) for more information.

mux(4) (streams-mux)

Multiplexing driver. This is a standard SVR 4.2 STREAMS driver. The mux driver is detailed in the UNIX System V Release 4 Programmer’s Manual – STREAMS. The mux(4) driver provides capabilities used primarily for validation test programs (see test-streams(8) as well as serving as an example multiplexing driver. This mux(4) driver also provides the minimux capabilities.

See mux(4) for more information.

nsdev(4) (streams-nsdev)

Named STREAMS device driver. This is a OpenSS7 specific driver. The nsdev(4) driver is a clone(4)-like driver that permits the specification of major and minor device numbers using the device node name. It provides one of three mechanisms under OpenSS7 that remove STREAMS driver dependency on statically allocated device numbers.

See nsdev(4) for more information.

nuls(4) (streams-nuls)

Null Stream driver. This is a standard SVR 4.2 STREAMS driver. The nuls(4) driver is usually called ‘null’. Linux has its own SVR3-style /dev/null driver, so it was renamed to ‘nuls’.

See nuls(4) for more information.

pipe(4) (streams-pipe)

STREAMS-based pipe driver. This is a standard SVR 4.2 STREAMS driver. However, pipe(4) is not normally implemented as a STREAMS driver, but is implemented as a system call. OpenSS7 provides pipe(2s) system call emulation which invokes this driver internal to the kernel.

See pipe(4) for more information.

sad(4) (streams-sad)

STREAMS Administrative Driver. This is a standard SVR 4.2 STREAMS driver. The sad(4) driver is used by the autopush(8) utility to examine and specify the autopush lists for STREAMS drivers. Also, it is used to examine and verify the present of STREAMS modules or drivers in the system.

See sad(4) for more information.

sfx(4) (streams-sfx)

STREAMS FIFO device driver. This is commonly implemented STREAMS driver that is used to implement STREAMS FIFOs (Named Pipes) using a regular character device. The sfx(4) driver provides a character based device approach to creating FIFOs.

See sfx(4) for more information.

spx(4) (streams-spx)

STREAMS pipe device driver. This is commonly implemented STREAMS driver that is used to implement STREAMS pipes using a regular character device. The spx(4) driver provides a character based device approach to creating FIFOs and pipes. Only UnixWare® and AIX(4) document this device.

See spx(4) for more information.

Additional drivers are provided by add-on packages.


3.3 Modules

The configuration of STREAMS drivers and modules is performed when compiling the OpenSS7 subsystem. The STREAMS subsystem, core drivers and modules are part of every OpenSS7 system.

The following lists the core drivers and modules, STREAMS kernel tunable parameters, and STREAMS configuration information:17

pipemod(4) (streams-pipemod)

Pipe module. This is a standard SVR 4.2 STREAMS module. The pipemod(4) module can be pushed over a pipe end or FIFO before other modules are pushed (on either end) to reverse the sense of the M_FLUSH(9) message that traverse the pipe.

See pipemod(4) for more information.

connld(4) (streams-connld)

Connection Line Discipline module. This is a standard SVR 4.2 STREAMS module. The connld(4) module can be pushed over a pipe end that has been attached to a file system file using fattach(3) and will then create a new pipe instance on each open(2s) of the attached file and pass the new remove file pointer to the remove end using M_PASSFP(9) to be received with I_RECVFD(7). This allows servers to be created that use pipe(4)s for communication.

See connld(4) for more information.

sc(4) (streams-sc)

STREAMS Configuration module. This is a commonly implemented STREAMS module. It is implemented by HP-UX and AIX, and perhaps other Mentat-derived STREAMS implementations. The sc(4) modules provides the ability to access STREAMS driver information by name rather than major device number. It also provides access to the module_info(9) and module_stat(9) structure information for the named STREAMS module or driver, not accessible using the sad(4) driver. The sc(4) module is used by the scls(8) utility.

See sc(4) for more information.

srvmod(4) (streams-srvmod)

Buffer module. This is a standard SVR 4.2 STREAMS module described in the UNIX System V Release 4 Programmer’s Manual – STREAMS. The srvmod(4) module also has OpenSS7 specific extensions. The srvmod(4) module is used by the perftest(8) performance test program to test the effect of additional levels of service procedure pushed over a Stream. The module also serves as an example of a STREAMS module using service procedures.

See srvmod(4) for more information.

nullmod(4) (streams-nullmod)

Null module. This is a standard SVR 4.2 STREAMS module described in the UNIX System V Release 4 Programmer’s Manual – STREAMS. The nullmod(4) module also has OpenSS7 specific extensions. The nullmod(4) module is used by the perftest(8) performance test program to test the effect of additional levels of put procedure pushed over a Stream. The module also serves as an example of a STREAMS module not using service procedures.

See nullmod(4) for more information.

testmod(4) (streams-testmod)

Test module. This is a OpenSS7 specific STREAMS module. The primary purpose of the testmod(4) modules is to provide the test-streams(8) validation test program with the capability to pass specific M_ERROR(9) and M_HANGUP(9) messages to the Stream head for POSIX validation testing. It also serves as an example of how a STREAMS module can properly process M_IOCTL(9) and related messages.

See testmod(4) for more information.

Additional modules are provided by add-on packages.


3.4 Libraries

During the installation process of OpenSS7 a subroutine library is built and installed on your system. For 64-bit systems that support 32-bit compatibility, two versions of each library are built and installed: one 64-bit native library and one 32-bit compatibility library. 64-bit native libraries are installed to the /usr/lib64 subdirectory. 32-bit native and 32-bit compatibility libraries are installed to the /usr/lib subdirectory.

libstreams.so.0.0.1
libstreams.so.0
libstreams.so

Provides a shared object library for use by STREAMS applications programs.

libstreams.a

Provides a static library for use by STREAMS applications programs.

libstreams.la

Provides the libtool definitions for the library.

3.4.1 libstreams Library Routines

The following routines are present in the libstreams libraries. The routines in these libraries are standard STREAMS interface system calls documented in the System V Release 4.2 Programmer’s Manual – STREAMS. Refer to the associated manual pages for detailed information on these routines.

fattach(2)

Name a STREAMS special file.

fdetach(2s)

Unname a STREAMS special file.

getmsg(2s)

Get next message off of a Stream.

getpmsg(2s)

Get next message off of a Stream.

isastream(2s)

3.4.2 Using the Library

To use one of the OpenSS7 libraries you can include the file sys/stropts.h in you application program source code. On you compiler command line, add the option ‘-I/usr/include/openss7’ to include the version of sys/stropts.h that is distributed with OpenSS7.

When linking our program, or performing a final gcc to build your executable, include one of the following options on your command line:

/usr/lib/libstreams.a
-lstreams -static

Link against the static version of the library.

-lstreams

Link against the shared object version of the library.

/usr/lib/libstreams.la

Use with libtool to link additional convenience libraries against the shared or static versions of the library.

Failure to link the executable runtime path for libstreams will result in linker-loader warnings that the functions getpmsg(2s) or putpmsg(2s) are not implemented and will always fail.18.

See also Development for more information.


3.5 Utilities


3.5.1 Init Scripts

Following are System V Init Scripts that are installed by the package:

specfs(8) (/etc/init.d/specfs)
specfs.sh(8) (/etc/init.d/specfs.sh)

System V Init Script for the STREAMS Special Shadow Filesystem. The specfs(8) init script provides the ability to initialize, configure and mount the STREAMS Special Shadow Filesystem, specfs(5). The specfs(8) script provides the RedHat-style init script, whereas the specfs.sh(8) script provides the Debian-style init script.

See specfs(8) for more information.

openss7(8) (/etc/init.d/openss7)
openss7.sh(8) (/etc/init.d/openss7.sh)

System V Init Script for the STREAMS Subsystem. The streams(8) init script provides the ability to initialize, configure and mount the STREAMS subsystem, STREAMS(9). The streams(8) script provides the RedHat-style init script, whereas the streams.sh(8) script provides the Debian-style init script.

See streams(8) for more information.


3.5.2 User Utilities

Following are user utilities for manipulating Streams:

strchg(1) (/usr/bin/strchg)

Change Stream configuration. strchg(1) is a standard SVR 4.2 STREAMS user utility.

strchg(1) is a C-language user program that can be used to alter the configuration of the Stream associated with the caller’s standard input. The strchg(1) command pushes modules on the Stream, pops modules off of the Stream, or both. Only the superuser or owner of the STREAMS device can alter the configuration of that Stream. If another user attempts to alter the configuration, the strconf(1) command will fail.

strchg(1) is useful from the shell and, when standard input is redirected from an open file descriptor to the command, can be used to push and pop modules from arbitrary Streams, not just those associated with STREAMS-based terminal devices.

See strchg(1) for more information.

strconf(1) (/usr/bin/strconf)

Query Stream configuration. strconf(1) is a standard SVR 4.2 STREAMS user utility.

strconf(1) is a C-language user program that can be used to query the configuration of a Stream. When use without any options, it prints a list of the modules in the Stream associated with the standard input, as well as the topmost driver. The list is printed with one name per line, where the first name printed is the topmost module on the Stream and the last item printed is the name of the topmost driver associated with the Stream.

strconf(1) is useful from the shell and, when standard input is redirected from an open file descriptor to the command, can be used to query arbitrary Streams, not just the associated with STREAMS-based terminal devices.

See strconf(1) for more information.

strreset(1) (/usr/bin/strreset)

Reset a Stream. strreset(1) is a standard SVR 4.2 STREAMS user utility.

strreset(1)is a C-language user program that resets an open Stream by generating an M_FLUSH(9) message to the Stream head. It is used mainly to reset blocked Streams. Wehn it is impossible to reopen the Stream, issue an I_FLUSH or equivalent command. This situation may happen with a process sleeping in a module’s close routine, when signals can not be sent to the process (a zombie process exiting, for example).

See strreset(1) for more information.

4 Development

For development using the OpenSS7 package, See About This Manual in STREAMS Programmer’s Guide.


4.1 Header Files

Header files are installed, typically, in the /usr/include/openss7 subdirectory. To use the header files from the package, ‘-I/usr/include/openss7’ must be included in the gcc command line as a compile option. This is true regardless of whether user space or kernel space programs are being compiled.

In general, ‘-I’ include directives on the gcc command line should be ordered in the reverse order of the dependencies between packages. So, for example, if the include files from all add-on packages are required, the order of these directives would be: ‘-I/usr/include/strss7 -I/usr/include/strsctp -I/usr/include/strinet -I/usr/include/strxnet -I/usr/include/strxns -I/usr/include/strcompat -I/usr/include/streams’.

4.2 Libraries

Shared or static versions of the libstreams library must be linked when using the openss7-1.1.7.20141001 package. This library must either be specified on the gcc command line as a shared library (e.g. ‘-lstreams’) or as a static library (e.g. ‘/usr/lib/libstreams.a’).

If the shared library is linked, include the following options on the gcc command line:

-lstreams

Link to the /usr/lib/libstreams.so shared library.

If the static library is linked, include the following options on the gcc command line:

/usr/lib/libstreams.a

Link to the /usr/lib/libstreams.a static library.


4.3 Kernel Modules

Developing STREAMS kernel modules is similar to user space programs with regard to header files. /usr/include/openss7 should be placed as an include directory to search in the gcc command line. The rules for compiling Linux kernel modules should be followed. In particular, several important intricacies should be considered:

  • The gcc compiler used to compile the kernel modules must be the same version of compiler that was used to compile the kernel.
  • The gcc command line must have the same compile flags that were used to compile the kernel.
  • The gcc command line must define several important kernel defines including ‘-DLINUX’, ‘-D__KERNEL__’, as well as the base name of the module.
  • The gcc command line must include several important include files directly on the command line such as ‘--include /lib/modules/3.0.99-1-unx/build/include/linux/autoconf.h’ and maybe even ‘--include /lib/modules/3.0.99-1-unx/build/include/linux/modversions.h’.19

5 Porting

OpenSS7 provides a rich set of STREAMS functions, DDI/DKI functions and utilities based on SVR 4.2 MP for the development of STREAMS modules and drivers. Although these functions and capabilities provide all of the utilities necessary for the development of STREAMS modules and drivers, it represents the common set of functions provided by other STREAMS implementations.

Some other STREAMS implementations provide interfaces, utilities and helper functions specific to those implementations. Where STREAMS implementations differ the most is in the manner in which they configure and register STREAMS drivers and modules for interface to the operating system, including registration functions, device numbering, creation of minor device nodes, administration and other mechanisms not specified by the System V Release 4 Programmer’s Guide – STREAMS.

To assist with porting of STREAMS drivers and modules from other STREAMS implementations and UNIX based operating systems to OpenSS7, OpenSS7 provides a separate STREAMS Compatibility add-on package, called strcompat-0.9.2.7,20 that provide source level compatibility with a wide range of mainstream STREAMS implementations and significant groups of compatibility and helper functions (such as those from Solaris and Mentat). These compatibility packages also provide separate demand loadable kernel modules that provide the additional compatibility functionality with OpenSS7.

In general, when porting to OpenSS7 from another STREAMS implementation, the following items will need the most attention:

Header Files

The STREAMS and operating system specific header files that must be included by kernel modules to implement STREAMS drivers or modules are specific to each STREAMS implementation. Although there are some basic header files to include (sys/stream.h, sys/strconf.h, sys/ddi.h, sys/cmn_err.h, sys/dki.h, sys/kmem.h), the order in which these headers are included and the additional operating system specific headers are implementation specific. See the example drivers and modules for the header files that are necessary for OpenSS7 STREAMS modules and drivers.

Kernel Module Mechanism

The mechanism for creating, configuring and loading kernel modules is specific to the operating system implementation. OpenSS7 uses the normal Linux mechanisms for kernel modules also for STREAMS drivers and modules.

Configuration and Registration

The STREAMS driver or module will need to be converted to use the OpenSS7 configuration and registration mechanisms. See register_strdev(9), unregister_strdev(9), register_strmod(9) and unregister_strmod(9) for more specific information on the OpenSS7 configuration and registration mechanisms.

Non-STREAMS DDI/DKI Facilities

Any of the non-STREAMS DDI/DKI facilities or operating system specific facilities that are used by the STREAMS driver or module may need to be replaced with the Linux equivalent. Examples of such facilities include basic locks, read-write locks, semaphores and mutexes, atomic integers, interrupt suppression, bus access and memory mapping functions.

Binary Modules

When STREAMS drivers or modules are released as binary objects and source code is not available, it is still possible to convert the binary module for use with OpenSS7. The facility to convert binary modules for use with OpenSS7 is not, however, part of the base package and is not part of the STREAMS Compatibility package. A separate add-on package, the Binary Compatibility Modules package, strbcm-0.9.2.5 was developed explicitly for this purpose.21


5.1 Porting from SVR 4.2 MP

When porting from SVR 4.2 MP or a STREAMS implementation based closely on SVR 4.2 MP, such as SUPER-UX, UXP/V, IRIX or many of the real-time operating system implementations (e.g. VxWorks), it is possible to port directly to OpenSS7 without using the STREAMS Compatibility package. Event when porting from AIX, HP-UX and OSF/1 it is possible to avoid using the compatibility package.

Most pseudo-device drivers and modules should not require any special facilities beyond basic locks and porting may be straightforward. Where extensive implementation specific DDI/DKI or operating system functions are required, it is better to use the STREAMS Compatibility package and modules closest to the specific implementation being ported from.


5.2 Porting from Solaris

When porting from Solaris there are both STREAMS facilities and extensive DDI/DKI facilities that differ greatly from basic SVR 4.2 MP STREAMS and DDI/DKI functions. For porting all but the most trivial of STREAMS drivers and modules written specifically for Solaris, it is better to use the STREAMS Compatibility package and the Solaris compatibility module provided by that package.22


5.3 Porting from UnixWare

When porting from UnixWare there are extensive operating system facilities that differ greatly from basic Linux facilities. For the most part these are basic locks, read-write locks, condition variables, sleep locks, atomic integers, bus access and mapping functions. Although Linux provides equivalents in most of these categories, the STREAMS Compatibility package contains a compatibility module for UnixWare that provides source compatibility with most of these functions. It is recommended that all but the most trivial of UnixWare drivers and modules use the STREAMS Compatibility package when porting.


5.4 Porting from Mentat

When porting a STREAMS driver or module from a Mentat implementation (such as AIX, HP-UX, OSF/1, Mac OT) that makes heavy use of the Mentatmi_’ or ‘mps_’ helper functions, it is best to use the OpenSS7 implementations of those functions available in the STREAMS Compatibility package directly. The STREAMS Compatibility package provides a Mentat Portable STREAMS compatibility module that provides implementations of the Mentat functions found in AIX, OSF/1 and Mac OT.23


6 Conformance


6.1 Standards Compliance

OpenSS7 was designed and implemented to be compliant with as many standards impinging on STREAMS as possible. There are three areas of standards compliance as follows:

6.1.1 User Interface Compliance

The STREAMS user interface standards are primarily specified by the IEEE and OpenGroup standards and take the form of the POSIX 2003 and Single UNIX Specification standards simultaneously released by the OpenGroup in conjunction with IEEE. The latest POSIX/IEEE/OpenGroup standard provide an XSI extension that includes the STREAMS user interface. For the most part, the OpenGroup XSI interface is completely compatible with the user interface described in the System V Release 4 Programmer’s Manual – STREAMS, and where it does not, Stream head options are provided to select between the default OpenGroup XSI behaviour and the traditional SVR 4 behaviour.

Most of the XSI specifications of the OpenGroup describe the behaviour of the Stream head and the behaviour of specific STREAMS drivers or modules (such as pipes, FIFOs and terminals). Also described is the poll(2s) behaviour, generation of signals, and read(2s) and write(2s) behaviour as it applies to STREAMS character special devices.

User interface compliance of the OpenSS7 is tested with custom validation test suites that ship with the package. See Conformance Test Programs for more information on conformance and validation test suites.

6.1.2 Service Interface Compliance

The OpenGroup (now and in previous incarnations) have issued standardized service interface specifications as part of the Common Application Environment (CAE) specifications. These service interface specifications usually concern networking interfaces such as the Data Link Provider Interface (DLPI), the Network Provider Interface (NPI), the Transport Provider Interface (TPI), the X/Open Transport Interface (XTI) and the Sockets API. Although these standards impinge upon various networking add-on packages for OpenSS7, they do not impinge upon the base STREAMS package documented here. See the Installation and Reference Manual for the appropriate add-on package.

6.1.3 Kernel Interface Compliance

The STREAMS kernel interfaces, DDI/DKI and other facilities available to the STREAMS driver or module writer has not been subjected to formal standardization. For the most part, the descriptions that are present in the System V Programmer’s Manual – STREAMS provide the most definitive ipso facto standard for STREAMS implementation. In addition to this, some STREAMS implementations have provided some enhancements or restrictions over the SVR 4 descriptions. Perhaps the most extensive embellishments have been provided for the Solaris implementation of STREAMS.

OpenSS7 has been implemented to provide maximum compatibility over a wide range of STREAMS implementations based on SVR 4 and provides additional capabilities similar to those specific embellishments found in implementations such as Solaris through an add-on STREAMS Compatibility package.

The most delicate areas of compatibility across STREAMS implementations regard, not the use of STREAMS or DDI/DKI functions from within the STREAMS environment, but the invocation of STREAMS functions from outside the STREAMS environment. In particular, use of private locks and synchronization in the face of interrupts and external asynchronous callbacks is where implementations deviate the greatest. OpenSS7 attempts to address these differences by providing a greater level of assurance and wider range of calling contexts for each of the STREAMS facilities.

Kernel interface compliance of the OpenSS7 to SVR 4 specifications is tested with custom validation test suites, test modules and test drivers that ship with the package. See Conformance Test Programs for more information on conformance and validation test suites.

When installing from the tarball (see Installing the Tar Ball), this distribution is probably compatible with a much broader array of distributions than those listed above. These are the distributions against which the current maintainer creates and tests builds.


7.2.2 Kernel

The OpenSS7 package compiles as Linux kernel modules. It is not necessary to patch the Linux kernel to build or use the package.28 Nor do you have to recompile your kernel to build or use the package. OpenSS7 packages use autoconf(1) scripts to adapt the package source to your existing kernel. The package builds and runs nicely against production kernels from the distributions listed above. Rather than relying on kernel versions, the autoconf(1) scripts interrogate the kernel for specific features and variants to better adapt to distribution production kernels that have had patches applied over the official kernel.org sources.

7.2.2.1 Compatible Kernels

The OpenSS7 package is compatible with 2.4 kernel series after 2.4.10 and has been tested up to and including 2.4.33. It has been tested from 2.6.3 up to and including 2.6.38 (with RHEL 6.0, SLES 11.1 and Debian 6.0 patch sets). It has been tested from 3.0 up to and including 3.14. Please note that your mileage may vary if you use a kernel more recent than 3.2: it is difficult to anticipate changes that kernel developers will make in the future. Many kernels in the 2.6 and 3.x series now vary widely by release version and if you encounter problems, try a kernel within the supported series.

SMP Kernels

UP validation testing for kernels is performed on all supported architectures. SMP validation testing was initially performed on UP machines, as well as on an Intel 3.0GHz Pentium IV 630 with HyperThreading enabled (2x). Because HyperThreading is not as independent as multiple CPUs, SMP validation testing was limited. Current releases have been tested on dual 1.8GHz Xeon HP servers (2x), 3.0GHz Pentium D (2x), dual quad-core SunFire (8x) servers and dual hex-core Xeon servers (12x).

XEN Kernels

It should be noted that, while the packages will configure, build and install against XEN kernels, that problems running validation test suites against XEN kernels has been reported. XEN kernels are explicitly not supported. This may change at some point in the future if someone really requires running OpenSS7 under a XEN kernel.

7.2.2.2 Linux Kernel Upgrades

The OpenSS7 package compiles as Linux kernel modules. Previously, kernel modules for each and every installed kernel were required. This is no longer the case. The kernel modules installed by the OpenSS7 package now support weak updates across a wide range of kernels in the series. This means that it is normally only necessary to build and install the OpenSS7 kernel modules for one kernel in a series. This is true for all supported 2.6 and 3.x kernel distributions (and likely for others as well).


7.2.3 Architectures

The OpenSS7 package compiles and installs on a wide range of architectures. Although it is believed that the package will work on all architectures supported by the Linux kernel being used, validation testing has only been performed with the following architectures:

  • ix86
  • x86_64
  • ppc (MPC 860)
  • ppc64

32-bit compatibility validation testing is performed on all 64-bit architectures supporting 32-bit compatibility. If you would like to validate an OpenSS7 package on a specific machine architecture, you are welcome to sponsor the project with a test machine.

Major changes for release openss7-1.1.1.20090908

This the third OpenSS7 Project respin of the OpenSS7 package. This is a production grade release. All existing validation test suites run clean on supported distributions, production kernels and architectures.

The OpenSS7 package has undergone significant changes, so follow closely. In it first incarnation, epoch zero (0), the openss7 package was an add-on package to a now deprecated version of STREAMS. This changed due to the deprecation of the old versions of STREAMS. In its second incarnation, epoch one (1), the openss7 package contained Linux Fast-STREAMS and a number of other sub-packages, each capable of building and installing separately. This changed due to the increasing maintenance overhead as additional sub-packages were added. In its latest incarnation, epoch two (2), the OpenSS7 package is a monolithic package containing Linux Fast-STREAMS and most of the other subpackages in a single build package.

Major feature additions since the last public release are:

  • - Support for CentOS 5.3 and 2.6.18-128.1.10.el5 kernel.
  • - Support for SLES 10 SP2.
  • - SNMP agents are more thorough and complete.
  • - Java JAIN SS7 OAM, MTP, SCCP, TCAP, INAP, MAP, ISUP, ISDN, H.323, IUA, M3UA, SUA, TUA, SPIRITS components, with JAIN JCC 1.2 and MSCONTROL.
  • - Interfaces provided for major scripting languages including Java, Tcl, Perl and Ruby using Swig.

Major packaging changes since the last public release, epoch one (1), are:

  • - The package only compiles with Linux Fast-STREAMS, which is included.
  • - Only OpenSS7 Project developed modules, drivers, libraries and utilities have been included.
  • - Forks of other test utilities such as Iperf and Netperf have been removed.
  • - Sub-package source and installation sub-directories have all been collapsed into the one openss7 sub-directory.
  • - A single tarball, SRPM and DSC generates a simple set of 3 binary RPMs or DEBs.
  • - The entire package is now released under the Affero GNU Public License Version 3; however, commercial licensing is also available for the entire package.

Major upgrades from the last public release are:

  • - Updated build system to swig-1.3.39.
  • - Updated build system to automake-1.11 with full silent build.
  • - Excluded deprecated sub-packages as follows:
    sctp-0.2.27
    iperf-2.0.8
    netperf-2.3.7
    osr61-0.9.2.3
  • - Documentation license for all documentation upgraded to GFDL 1.3 with no Invariant Sections, no Front-Cover Texts and no Back-Cover Texts, for full Debian policy compatibility.
  • - Updated build system tool chain to m4-1.4.13, automake-1.10.2, bison-2.4.1, libtool-2.2.6a, texinfo-4.13a.
  • - Addition of the following sub-packages:
    stratm-0.9.2.1

    This subpackage was then instantly absorbed into the new OpenSS7 package.

  • - Significant feature updates were made to:
    strchan-0.9.2.4
    strsock-0.9.2.4
    strnsl-0.9.2.4
    sigtran-0.9.2.4
  • - Significant rework of the strchan sub-package into the strss7, strisdn, strx25 and striso packages. One single driver now meets the needs of all sub-packages.
  • - Completion of the strsock package, moves from pre-alpha to beta.
  • - The strnsl subpackage moves from alpha to production.
  • - Significant completion of the sigtran package: all components moved back to production.

Major maintenance items since the last public release are:

  • - Fixed hash races in open and close. This was service affecting under heavy open/close loads. (Bug# openss7 006.)
  • - Fixed reference counting imbalance when entering and leaving synchronization queues. (Bug# openss7 005.)
  • - Fixed reference counting imbalance when syncrhonization queues are used on module. (Bug# openss7 004.)
  • - Fixed timer reporting in the pstrlog() call resulting in near-epoch invalid timestamps. This was an annoyance. (Bug# openss7 003.)
  • - Fixed assurances in untimeout and unbufcall utilities. This could be service affecting on many-way machines. (Bug# openss7 002.)
  • - Timer cancellation directly from ICS races removed. This could be service affecting on many-way machines. (Bug# openss7 002.)
  • - Corrected removal of SLAP_NO_REAP flag from recent kernels causing timeout problems on many-way machines under memory pressure. (Bug# openss7 001.)

For complete detail on maintenance items, see BUGS in the release.

This is a public, stable, production grade release of the package: it deprecates previous releases. Please upgrade to the current release before reporting bugs.

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(8) and dpkg(1) based distributions, and can be used on production kernels without patching or recompiling the kernel.

This package is publicly released strictly under the GNU Affero General Public License Version 3; however, commercial licensing is available. The release is available as an autoconf(1) tarball, SRPM, DSC, and a set of binary RPMs and DEBs for popular distributions. See the package page for the autoconf(1) tarballs, SRPMs, DSCs and binary RPMs and DEBs. See the repository page for information concerning network installation and update sources.

Major changes for release openss7-1.1.1.20090901

This release was only released internally.


Major changes for release openss7-1.1.1.20090622

This release was only released internally.


Major changes for release openss7-0.9.2.G

This is the sixth public release of the OpenSS7. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures.

The OpenSS7 is not released as often as the sub-packages. As sub-packages are released more often, to rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains.

Major features since the last public release are as follows:

  • - License upgrade to AGPL Version 3.
  • - Modifications to build under Fedora2.6.22.5-49’ kernel. These changes also support ‘2.6.22.9-91.fc7’ kernel. Modifications to build under Fedora2.6.25-45.fc9’ and ‘2.6.26.5-45.fc9’ kernels. Documented lib32gcc1 problem on Ubuntu. Noted problem running under XEN kernels. XEN kernels are not yet supported. Added MODULE_VERSION to all modules and drivers.
  • - Ability to strap out major documentation build and installation primarily for embedded targets. Improvements to common build process for embedded and cross-compile targets. Cross-compile fixes (strap out AC_FUNC_REALLOC macro when cross-compiling). Conversion of RPM spec files to common approach for major subpackages.

    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.

  • - Higher performance and updated performance papers.
  • - Updated tool chain to m4-1.4.12, autoconf-2.63 and texinfo-4.13. Support for flex 2.5.33 in maintainer mode.
  • - Updated references database for manual pages and roff documents.
  • - Added the following major sub-packages to the master build (and release):
    strx25-0.9.2.1
  • - All of the major subpackages that are at production release have maintenance upgrades for new production kernels, distributions and tool chains. Many of the major subpackages have greatly expanded documentation and provide additional modules and drivers not previously available in public releases. Significant feature updates were made to:
    strxns-0.9.2.7
    strinet-0.9.2.7
    strchan-0.9.2.4
    strx25-0.9.2.1
    striso-0.9.2.4
    strss7-0.9a.8
    sigtran-0.9.2.4

    Please see the individual NEWS files in each of the subpackages for more information.

This is a public stable production grade release of the package: it deprecates previous releases. Please upgrade to the current release before reporting bugs.

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 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. For tarballs, SRPMs, DSCs and binary RPMs and DEBs, see the openss7 package page.

Major changes for release openss7-0.9.2.F

This is the fifth public release of the OpenSS7. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures.

The OpenSS7 is not released as often as the sub-packages. As sub-packages are released more often, to rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains.

Major features since the last public release are as follows:

  • - Support build on openSUSE 10.2.
  • - Support build on Fedora 7 and 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.

Major changes for release openss7-0.9.2.E

This is the fourth public release of the OpenSS7. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures.

It is unlikely that the OpenSS7 will be released as frequently as before. Sub-packages will be released more often. To rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains.

Major features since the last public release are as follows:

  • - Addition of the osr61 sub-package that contains Dialogic® Open System Release 6.1 version 239 GPL drivers.
  • - A few minor corrections to the common build process.
  • - Support for autoconf 2.61, automake 1.10 and gettext 0.16.
  • - Support for Ubuntu 6.10 distribution and bug fixes for i386 kernels.
  • - The package now looks for subpackages with a version number as unpacked by separate tarball.

Major changes for release openss7-0.9.2.D

This is the fourth public release of the OpenSS7. The sub-packages have been reorganized for this release. See README in the release for a sub-package listing. Aside from sub-package reorganization, the major difference from previous release is that this release no longer contains LiS. Too many of the sub-packages will not even build against LiS because of its Stream head deficiencies.

Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures. The packages build better Debian/Ubuntu .deb files.

It is unlikely that the OpenSS7 will be released as frequently as before. Sub-packages will be released more often. To rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package.

The release provides the following enhancements and fixes:

  • - Added the following sub-packages to the master build (and release):
    strnsl-0.9.2.1
    strbcm-0.9.2.1
    striso-0.9.2.1
    strsock-0.9.2.1
    strtty-0.9.2.1
    strutil-0.9.2.1
  • - Automated release file generation making for vastly improved and timely text documentation present in the release directory.
  • - This release candidate includes the changes made to the strsctp drivers at the 2006 SCTP Interop at the University of British Columbia. This version was interoperability tested with all implementations present.
  • - Better support for Ubuntu and recent gcc compilers, including debian script corrections.
  • - Support for most recent 2.6.18 kernels (including Fedora Core 5 with inode diet patchset).
  • - Now builds 32-bit compatibility libraries and tests them against 64-bit kernel modules and drivers. The ‘make installcheck’ target will now automatically test both 64-bit native and 32-bit compatibility versions, one after the other, on 64-bit platforms.
  • - Added versions to all library symbols.
  • - Many documentation updates for all OpenSS7 packages.
  • - Dropped support for LiS.
  • - Start assigning majors at major device number 231 instead of major device number 230. Assign major device number 230 explicitly to the clone device. Package will now support extended ranges of minor devices on 2.6 kernels under Linux Fast-STREAMS only. streams now supports expanded addressable minor device numbers, permitting 2^16 addressable minor devices per major device number on 2.6 kernels: LiS cannot support this change.
  • - Better detection of SuSE distributions, release numbers and SLES distributions: support for additional SuSE distributions on ix86 as well as x86_64. Added distribution support includes SLES 9, SLES 9 SP2, SLES 9 SP3, SLES 10, SuSE 10.1.
  • - Improvide compiler flag generation and optimizations for recent gcc compilers and some idiosyncratic beahviour for some distributions (primarily SuSE).
  • - Optimized compilation is now available also for user level programs in addition to kernel programs. Added new ‘--with-optimize’ option to configure to accomplish this.
  • - Added ‘--disable-develconfigure option to suppress building and installing development environment. This feature is for embedded or pure runtime targets that do not need the development environment (static libraries, manual pages, documentation).
  • - Added send-pr script for automatic problem report generation.
  • - Each package will not build doxygen(1) html documentation with the ‘make doxy’ target. See ‘make help’ or README-make in the distribution for more information.

Major changes for release openss7-0.9.2.D.rc3

Third release candidate.

  • - The package will now build doxygen(1) html documentation with the ’doxy’ make target. See ’make help’ or README-make in the distribution for more information.
  • - Now builds 32-bit compatibility libraries and tests them against 64-bit kernel modules and drivers. The ‘make installcheck’ target will now automatically test both 64-bit native and 32-bit compatibility versions, one after the other, on 64-bit platforms.
  • - Added complete documentation and Installation and Reference Manual for the OpenSS7 (this manual).
  • - Added the following sub-packages to the master build (and release):
    strbcm-0.9.2.1
    striso-0.9.2.1
    strsock-0.9.2.1
    strtty-0.9.2.1
    strutil-0.9.2.1
  • - Automated release file generation making for vastly improved and timely text documentation present in the release directory.
  • - Dropped support for LiS.
  • - Sub-packages will now support extended ranges of minor devices on 2.6 kernels under Linux Fast-STREAMS only.
  • - This release candidate provides support for additional SuSE distributions on ix86 as well as x86_64. Added distribution support includes SLES 9, SLES 9 SP2, SLES 9 SP3, SLES 10, SuSE 10.1.
  • - This release candidate includes the changes made to the strsctp drivers at the 2006 SCTP Interop at the University of British Columbia. This version was interoperability tested with all implementations present.

This was an subscriber release.


Major changes for release openss7-0.9.2.D.rc2

Second release candidate.

This release candidate also contains the results of performance testing of the new second generation UDP driver (implemented completely in STREAMS instead of using an internal socket).

This release candidate also contains support for SuSE 10.1.

This was an subscriber release.


Major changes for release openss7-0.9.2.Drc1

First release candidate.

  • - Release candidate for Mark Fugate.
  • - Added –enable-devel configure option for embedded targets.
  • - Added send-pr script for automatic problem report generation.

This was an subscriber release.


Major changes for release openss7-0.9.2.C

Distribution check for entire master package. Trying to get master package into form where it can be released as a complete package.

This was a public release.


Major changes for release openss7-0.9.2.B

Minor changes for wider release, better master packaging and bug fixes.

This was a public release.


Major changes for release openss7-0.9.2.A

With this release version numbers were changed to reflect an upstream version only to be consistent with other OpenSS7 package releases. All RPM release numbers will be -1$(PACKAGE_RPMEXTRA) and all Debian release numbers will be ‘_0’. If you wish to apply patches and release the package, please bump up the release number and apply a suitable release suffix for your organization. We leave Debian release number _1 reserved for your use, so you can still bundle the source in the .dsc file.

Major changes for this release include build against Linux 2.6 kernels and popular distributions based on the 2.6 kernel as well as wider distribution support.

This was a public release.


Initial release openss7-0.9.2-1

Initial autoconf/RPM release of the OpenSS7 master package.

This master package contains all other OpenSS7 releases.


7.4 Maturity

The OpenSS7 Project adheres to the following release philosophy:

  • pre-alpha release
  • alpha release
  • beta release
  • gamma release
  • production release
  • unstable release

7.4.1 Pre-Alpha Releases

Pre-alpha releases are releases that have received no testing whatsoever. Code in the release is not even known to configure or compile. The purpose of a pre-alpha release is to make code and documentation available for inspection only, and to solicit comments on the design approach or other characteristics of the software package.

Pre-alpha release packages ship containing warnings recommending that the user not even execute the contained code.


7.4.2 Alpha Releases

Alpha releases are releases that have received little to no testing, or that have been tested and contains known bugs or defects that make the package unsuitable even for testing. The purpose for an alpha release are the same as for the pre-alpha release, with the additional purpose that it is an early release of partially functional code that has problems that an external developer might be willing to fix themselves and contribute back to the project.

Alpha release packages ship containing warnings that executing the code can crash machines and might possibly do damage to systems upon which it is executed.


7.4.3 Beta Releases

Beta releases are releases that have received some testing, but the testing to date is not exhaustive. Beta release packages do not ship with known defects. All known defects are resolved before distribution; however, as exhaustive testing has not been performed, unknown defects may exist. The purpose for a beta release is to provide a baseline for other organizations to participate in the rigorous testing of the package.

Beta release packages ship containing warnings that the package has not been exhaustively tested and that the package may cause systems to crash. Suitability of software in this category for production use is not advised by the project; however, as always, is at the discretion of the user of the software.


7.4.4 Gamma Releases

Gamma releases are releases that have received exhaustive testing within the project, but external testing has been minimal. Gamma release packages do not ship with known defects. As exhaustive internal testing has been performed, unknown defects should be few. Please remember that there is NO WARRANTY on public release packages.

Gamma release packages typically resolve problems in previous beta releases, and might not have had full regression testing performed. Suitability of software in this category for production use is at the discretion of the user of the software. The OpenSS7 Project recommends that the complete validation test suites provided with the package be performed and pass on target systems before considering production use.


7.4.5 Production Releases

Production releases are releases that have received exhaustive testing within the project and validated on specific distributions and architectures. Production release packages do not ship with known defects. Please remember that there is NO WARRANTY on public release packages.

Production packages ship containing a list of validated distributions and architectures. Full regression testing of any maintenance changes is performed. Suitability of software in this category for production use on the specified target distributions and architectures is at the discretion of the user. It should not be necessary to preform validation tests on the set of supported target systems before considering production use.


7.4.6 Unstable Releases

Unstable releases are releases that have received extensive testing within the project and validated on a a wide range of distributions and architectures; however, is has tested unstable and found to be suffering from critical problems and issues that cannot be resolved. Maintenance of the package has proved impossible. Unstable release packages ship with known defects (and loud warnings). Suitability of software in this category for production use is at the discretion of the user of the software. The OpenSS7 Project recommends that the problems and issues be closely examined before this software is used even in a non-production environment. Each failing test scenario should be completely avoided by the application. OpenSS7 beta software is more stable that software in this category.


7.5 Bugs


7.5.1 Defect Notices

OpenSS7 could contain unknown defects. This is a beta release. Some defects could be harmful. Validation testing has been performed by the OpenSS7 Project on this software for only a restricted set of systems. The software might fail to configure or compile on other systems. The OpenSS7 Project recommends that you do not use this software for purposes other than validation testing and evaluation, and then only with care. Use at your own risk. Remember that there is NO WARRANTY.29

This software is beta software. As such, it might crash your kernel. Installation of the software might mangle your header files or Linux distribution in such a way as to make it unusable. Crashes could lock your system and rebooting the system might not repair the problem. You can possibly lose all the data on your system. Because this software might crash your kernel, the resulting unstable system could possibly destroy computer hardware or peripherals making them unusable. You might void the warranty on any system on which you run this software. YOU HAVE BEEN WARNED.


7.5.2 Known Defects

With the exception of packages not originally created by the OpenSS7 Project, the OpenSS7 Project software does not ship with known bugs in any release stage except pre-alpha. OpenSS7 had no known bugs at the time of release.


7.5.3 Defect History

This section contains historical bugs that were encountered during development and their resolutions. This list serves two purposes:

  1. It captures bugs encountered between releases during development that could possibly reoccur (and the Moon is made of blue cheese). It therefore provides a place for users to look if they encounter a problem.
  2. It provides a low overhead bug list between releases for developers to use as a TODO list.

Bugs

Some portions of this package are not completely implemented yet, so the bugs for those portions are still being designed and will not be available until a later date. Most of the package is complete and for the most part bugs are currently available.

openss7 009. 2010-12-14T07:29:58+0000

Found a bug in msgpullup(9) that caused it to always fail. Strange enough, msgpullup(9) only attempted after pullupmsg(9) failed in all OpenSS7 drivers and modules.

*fixed* in openss7-1.1.1.20110111

openss7 008. 2010-08-09T17:41:46+0000

The t_alloc(3) function was incorrectly returning a TLOOK error when called when an outstanding event was pending. Thanks to John Hodgkinson at Boldon James for reporting this bug. A similar bug was found by inspection for t_bind(3), t_getinfo(3), t_getprotaddr(3).

*fixed* in openss7-1.1.1.20110111

openss7 007. 2010-06-09T12:13:41+0000

The t_rcv(3) function was not reseting data when the amount of data to be read was exactly the amount of data available. Thanks to John Hodgkinson at Boldon James for reporting this bug.

*fixed* in openss7-1.1.1.20111011

openss7 006. 2009-08-31T04:04:52+0000

A number of functions in strlookup.c were moving the found item in the hash collision list to the head of the list; however, a number of these functions were being called with a read lock instead of a write lock on the corresponding hash table. This caused crashes on kernels checking for list corruption on SMP machines under heavy open/close loads. The movement of the found entry to the head of the collision list has dubious performance advantages (as the hash entries are cached). Therefore, the practice has been removed (actually suppressed). Thanks to Tony Abo at HiTech for the report leading to this bug.

*fixed* in openss7-1.1.1.20090908

openss7 005. 2009-06-13T03:47:32+0000

There was an qput(9)/qget(9) reference counting imbalance in the enter_syncq_writer(9), enter_inner_syncq_func(9) and enter_inner_syncq_putp(9) functions. The most symptomatic of these was the enter_inner_syncq_putp(9) function that affected regular put(9s) and putnext(9) functions on synchronized modules and drivers having an inner perimeter. The reference imbalance resulted in leaking the module queue pair, stream head and stream head queue pair on driver close.

*fixed* in openss7-1.1.1.20090908

openss7 004. 2009-06-12T08:16:08+0000

qattach(9) was taking a reference on a synchronization queue without the reference being released in qdelete(9). qdelete(9) was fixed to release the reference taken by setsq(9) in qattach(9). Thanks to Tony Abo at HiTech for identifying and reporting this bug.

*fixed* in openss7-1.1.1.20090908

openss7 003. 2009-04-17T11:56:06+0000

The strace, strerr daemons and the pstrlog call in the streams library were not initializing ltime before the call to ctime_r(3) resulting in an epoch timestamp (Jan 1, 1970). Thanks to Pierre Crepieux for identifying and reporting this bug.

*fixed* in openss7-1.1.1.20090908

openss7 002. 2009-03-26T07:56:40+0000

Untimeout and unbufcall did not wait until the callback returned before returning when there was a collision between a cancellation of an event and the callback for the event. Linux Fast-STREAMS now makes this assurance, provided that the cancellation is not being invoked from within the same thread as the callback (i.e. untimeout called from an ISR interrupting the callback, or, say, from the callback itself) in which case it returns immediately.

Also, additional timer problems were encountered. Cancelling timers from within an ISR did not have sufficient list protection (irq suppression) potentially resulting in list corruption or queue reference counting problem.

*fixed* in openss7-1.1.1.20090908

openss7 001. 2008-12-16T08:17:47+0000

Somewhere about Linux kernel ‘2.6.17’, and during the openss7-0.9.2.D.rc2 master package release, it was discovered that SLABs no longer supported the SLAB_NO_REAP flag. Unfortunately, the seinfo_ctor(9) function was assuming that the SLAB_NO_REAP flag was being recognized. This means that over the span of some several days on system heavily using timers that a slab corruption would eventually occur resulting in a kernel crash, particularly on x86_64 kernels. The ‘seinfo’ slab functions have been rewritten to not expect the SLAB_NO_REAP feature. There was also a minor possibility of a strevent structure identifier overlap after an extremely long period of intensive operation, and that has been fixed as well. Thanks to Angel Diaz for reporting this bug.

*fixed* in openss7-1.1.1.20090908

strinet 004. 2008-10-24T08:04:16+0000

UDP and RAWIP drivers cannot receive zero-length messages in accordances with UNIX ’98 and XNS 5.2. Use the UDP2 and RAWIP2 drivers instead if this is important to you as they exhibit full UNIX ’98 XNS 5.2 conformance.

*fixed* in strinet-0.9.2.7

strcompat 008. 2008-10-19T19:57:41+0000

mi_open_link(9) was not walking device lists correctly.

*fixed* in strcompat-0.9.2.7.

strcompat 007. 2008-10-19T10:39:26+0000

mi_open_link(9) was not returning the assigned device number in devp when sflag was CLONEOPEN.

*fixed* in strcompat-0.9.2.7.

streams 025. 2008-10-17T05:57:29+0000

putnext(q, mp)’ was checking whether procedures had been turned off on queue ‘q’. This was not correct as it is only the ‘q->q_next’ put procedure that would be executed. It should only check procedures on ‘q->q_next’.

*fixed* in streams-0.9.2.4

streams 024. 2008-10-11T19:36:41+0000

A list delete corruption bug in the STREAMS driver and module lookup functions (e.g. __cdrv_lookup) was discovered by the list debugging in the FC9 kernel.

*fixed* in streams-0.9.2.4

streams 023. 2008-10-11T19:36:23+0000

Not really a bug, but newer (2.6.25) kernels no longer permit registration of binary identifiers for sysctls (i.e. ctl_name). The proc filesystem entries (i.e. procname) are still permitted and ctl_name should be set to zero for these kernels. Added a check for the existence of symbol sysctl_check_table(9) to identify when binary registration is forbidden. Another related problem is that when binary registration of system controls is not possible, sysctl(2) becomes worthless. Unfortunately, the STREAMS MIB agent was written to use sysctl(2) and needs to be rewritten to use the /proc/sys filesystem instead ala sysctl(8).

*fixed* in streams-0.9.2.4

streams 022. 2008-10-07T18:40:25+0000

When overriding 32-bit compatability on input-output controls conflicting from the CDROM block device with STREAMS input-output controls, the override was not properly passing CDROM input-output controls through due to a missing break statement in the override loop. This bug affected pre-2.6.11 kernels, likely manifesting itself in a non-function CDROM device while STREAMS was loaded. Bug reported and one-line fix provided by Sylvain Chouleur for DGAC.

*fixed* in streams-0.9.2.4

strxns 003. 2008-09-03T06:10:28+0000

Over-restricted settable range of tos in np_ip driver. Thanks to Christophe Nolibos for reporting this bug.

*fixed* in strxns-0.9.2.7

strnsl 004. 2008-08-20T06:02:09+0000

To permit the xnsl library to be used on systems with the broken libtirpc package, we now place the file in /etc/netconfig.xnsl instead of /etc/netconfig where the broken libtirpc package for GNU/Linux expects a broken /etc/netconfig configuration file. The library has been adjusted to first look for /etc/netconfig.xnsl before looking for /etc/netconfig.

*fixed* in strnsl-0.9.2.4.

strss7 006. 2008-08-17T03:42:23+0000

The xnet library was discovered to contain a thread-safety bug caused by newer behaviour of pthread_once(3) causing the library to core dump when used on recent implementations of pthreads (nptl).

The xnet library is no longer normally compiled as part of the strss7 package.

*fixed* in strss7-0.9a.8.

strsock 001. 2008-08-17T03:42:23+0000

The socket, socklib and sockpath libraries were discovered to contain a thread-safety bug caused by newer behaviour of pthread_once(3) causing the libraries to core dump when used on recent implementations of pthreads (nptl).

*fixed* in strsock-0.9.2.4.

strnsl 003. 2008-08-17T03:42:23+0000

The xnsl library was discovered to contain a thread-safety bug caused by newer behaviour of pthread_once(9) causing the library to core dump when used on recent implementations of pthreads (nptl).

*fixed* in strnsl-0.9.2.4.

strxnet 001. 2008-08-17T03:42:23+0000

The xnet and xnsl libraries were discovered to contain a thread-safety bug caused by newer behaviour of pthread_once(3) causing the libraries to core dump when used on recent implementations of pthreads (nptl).

*fixed* in strxnet-0.9.2.12.

strinet 003. 2008-08-02T02:58:49+0000

Some test cases are failing for the TCP driver when SELinux is set for Enforcing. Either the STREAMS kernel threads kstream/0, etc. need to be permitted or SELinux must be set to Permissive or Disabled. Conditions were added to the testsuite to expect failures on 30 specific tests when SELinux is set to Enforcing.

*addressed* in strinet-0.9.2.7

streams 021. 2008-08-01T22:32:08+0000

When flushing queues the backenable bits were not being initialized to zero in __flushq(9), resulting in back-enabling of bands (or the normal queue) was being performed depending on the uninitialized values in the backenable bit array. This only affected I_SETSIG signals for SWRNORM and SWBAND, and the only when flushing queues. Fix properly initializes the backenable array.

*fixed* in streams-0.9.2.4

streams 020. 2008-07-31T04:59:41+0000

Not really a bug (for STREAMS), but when the streams.ko kernel module is loaded, the crash(8) debugger will not debug a running kernel because it finds the runqueues(9) exported function in the streams.ko module instead of the the static one from the kernel. This has been temporarily renamed by macro to srunqueues(9) (notice the leading ‘s’) until crash(8) learns to do the right thing and check that the symbol it looks up comes from the kernel instead of a kernel module.

*workaround* in streams-0.9.2.4

streams 019. 2008-07-25T22:41:47+0000

When M_READ was being issued by the Stream Head downstream an srlock(0) imbalance in strsendmread(9) was causing soft-lockups on close for recent read-write lock implementations on CentOS 5.2 for ‘x86_64’.

*fixed* in streams-0.9.2.4

streams 018. 2008-07-25T01:15:26+0000

Previous fix didn’t work too good: returning [EAGAIN] when hung-up on getmsg(2s), getpmsg(2s), read(2s), readv(2s) instead of 0 and terminal end of file. This caused a regression on four or five other test cases.

*fixed* in streams-0.9.2.4

strcompat 006. 2008-07-11T13:52:04+0000

lis_alloc_sem() was not setting the supplied count against the created semaphore, but was alway setting the semaphore to 1 (unlocked).

*fixed* in strcompat-0.9.2.7.

strcompat 005. 2008-05-26T14:06:22+0000

lis_register_strdev() was failing whenever nminor was greater than zero or not an even multiple of 256. This was due to an error in the logic checking for multiple majors. (Thanks to Omer Tunali for reporting this bug.)

*fixed* in strcompat-0.9.2.7.

streams 017. 2008-04-10T15:17:30+0000

When M_DATA is sent upstream followed by M_HANGUP, read(2s) is returning zero (0) and not permitting the data associated with the M_DATA to be read. This is a bug per documentation. read(2s) should operate as normal following a hangup until all data is read and then return zero (0).

The difficulty is that when waking up from a read sleep or when entering read the hangup condition was generating an internal [ESTRPIPE] error. This was altered so that [ESTRPIPE] is only returned during the hangup condition after the read queue has been tested and the caller is about to sleep on read.

Test cases 3.2.1, 3.5.1 and 3.6.1 in the test-streams test suite executable were altered to validate the fix for this case and curtail regressions.

*fixed* in streams-0.9.2.4

streams 016. 2007-11-14T17:23:57+0000

Read is blocking when data has been read, O_NONBLOCK and O_NDELAY unset, RFILL unset, in non-SVR4 mode. This violates POSIX specifications.

Test case 3.1.11.4 in the test-streams test suite executable was generated to validate the fix for this case and to curtail regressions.

*fixed* in streams-0.9.2.4

streams 015. 2007-11-14T17:19:01+0000

Dynamic allocation of major device numbers is not working on recent 2.6 kernels. Someone slipped some code in the kernel to have register_chrdev(9) allocate from major 255 down (again). Changed code to allocate modid according to our own rules and then request the same for a major device number. This also ensures that module ID and major are the same.

*fixed* in streams-0.9.2.4

strchan 001. 2007-10-15T16:17:08+0000

Removing definition of freezestr(9) and unfreezestr(9) in ch_pmod.c and mx_pmod.c was causing loss of version information on old 2.4 kernels. Workaround is to use the _SUN versions as is until it can be fixed in streams or strcompat.

*fixed* in strchan-0.9.2.4

strsctp 007. 2007-07-21T21:06:48-0600

It was discovered that many network devices were claiming to have hardware checksum capability by setting the NETIF_HW_CSUM flag, but did not support SCTP checksum offload.

*workaround* in strsctp-0.9.2.8

The workaround is to ignore the flag for now. Either Linux network drivers need to start supporting SCTP checksum when they set the NETIF_HW_CSUM flag, or there needs to be some flag provided for SCTP. The workaround is to not believe that the driver does SCTP checksum offload when NETIF_HW_CSUM is set.

strsctp 006. 2007-07-21T21:05:10-0600

It was detected that the XTI_SNDBUF and XTI_RCVBUF options were not being set correctly (in fact, not being set at all).

*fixed* in strsctp-0.9.2.8

XTI_SNDBUF now limits the maximum available send window. XTI_RCVBUF now alters the advertized receive window.

openss7 002. 2007-07-21T17:26:01-0600

It was reported that validation test suites for XEN kernels are failing. XEN kernels are, therefore, not supported. (Thanks to Bryan Shupe at Flying J for reporting this bug.)

strcompat 004. 2007-07-21T17:26:01-0600

It was reported that, even with the fix below, validation test suites for XEN kernels are failing. XEN kernels are, therefore, not supported. (Thanks to Bryan Shupe at Flying J for reporting this bug.)

strcompat 003. 2007-07-21T17:22:10-0600

It was reported that paddr_t is already defined in recent XEN kernels, causing compile to fail for these kernels. (Thanks to Bryan Shupe at Flying J for reporting this bug.)

*fixed* in strcompat-0.9a.7.rc1.

A check was added to the configure script to check for the existence of paddr_t.

strss7 005. 2007-07-21T17:15:02-0600

It was discovered that recent kernel on RHAS4 are defining irq_handler_t but have the old 3 argument function template for irq handlers. The detection logic assumed that if irq_hander_t existed, that the newer 2 argument function template for irq handlers were in effect. This caused builds to fail on these RHAS4 kernels.

*fixed* in strss7-0.9a.8.rc1.

A check was added to the configure script to test whether the irq_handler_t has the newer 2 argument template.

openss7 001. 2007-06-27T08:53:51+0000

A report was made by Chris from Sandia that the build process choked on building 32-bit libraries and applications on an x86_64 system under Ubuntu Fiesty (7.04). While most other distributions include the gcc 32-bit compatibility libraries for 64-bit architectures with a 32-bit emulation mode, Ubuntu (and maybe Debian too) does not. The Ubuntu 7.04 package that is missing is the lib32gcc1 package. There are two workarounds to this difficulty: add the lib32gcc1 package (with apt), or add the ‘--disable-32bit-libs’ flag to ‘configure’.

*noted* in openss7-0.9.2.G

strnsl 002. 2007-06-20T15:22:19-0600

The libtirpc package for current releases of GNU/Linux including NFS4 has usurped a broken /etc/netconfig file for use by its broken implementation of TI-RPC. So when strnsl and more importantly the strinet package installs its /etc/netconfig entries, the libtirpc package breaks. To avoid this problem, I think that the best approach is to install a libtirpc entry (or a copy of the broken /etc/netconfig) into the /etc/netconfig.d subdirectory when strnsl installs and restore it to /etc/netconfig when strnsls removes.

Fixed in the current release: the actual fix involves not calculating the /etc/netconfig file from the /etc/netconfig.d subdirectory entries when an /etc/netconfig file exists that we have not generated.

strsctp 005. 2007-05-18T07:06:33+0000

Found the most obnoxious of bugs. When testing on loopback, more than 255 calls were being made to dupb(9) causing the db_ref field of the data block to wrap to zero, causing an incorrect reference count.

*fixed* in strsctp-0.9.2.7

streams 014. 2007-05-17T21:48:24+0000

The dupb(9) utility had an obnoxious bug where it permitted the db_ref count to wrap to zero, causing buffer allocation and freeing problems. This was very difficult to debug. dupb(9) now fails if the reference count has reached 255. When dupb(9) fails, the user should check if the reference count has reached 255, and if it has, attempt a deep copyb(9) instead. At some point it might be useful to have STREAMS do the deep copy automatically. This was discovered in strsctp loopback tests where message blocks are rapidly duplicated for retransmission.

*fixed* in streams-0.9.2.3

streams 013. 2007-05-17T21:48:06+0000

The log driver, strace, strerr and strclean utilities had some bugs. The strsctp driver now makes extensive use of strlog(9) trace and error logging and the log driver and utilities have been corrected. These facilities are now production grade.

*fixed* in streams-0.9.2.3

streams 012. 2007-04-13T01:47:30+0000

It appears that Ubuntu 6.10 has a rather broken implementation of the LSB install_init that has been inherited from Debian (a python script, none the less). This implementation refuses to properly install a disabled service (one with an empty or missing Default-Start: tag), but, rather invokes updated-rc.d in such a way that the init script is started at runlevels ‘2 3 4 5’ instead. This was causing problems with the strace and strerr services which are normally installed disabled.

This uncovered the fact that the Debian-style init scripts were not working anyway. The scripts have been fixed and the strace and strerr utilities now default to enabled.

*fixed* in streams-0.9.2.3

streams 011. 2007-04-10T10:56:42+0000

The strbcflag flag was never being cleared, causing infinite looping of the scheduler once the maximum number of buffers was reached. This also revealed a problem that bufcalls were being run unncecessarily (when strbcwait was set, instead of only when strbcflag was set).

*fixed* in streams-0.9.2.3

streams 010. 2007-04-10T10:55:29+0000

The stream event sequence number was wrapping and becoming larger than the event mask resulting in inability to cancel buffer callbacks and timeouts.

Option handling bug in ldltest.

*fixed* in strxns-0.9.2.6

streams 009. 2007-04-02T11:57:35+0000

ldl was using an incorrect MKDEV command, but when the Stream head attempted to redirect the open to the new (mangled) major device number, it properly returned ENXIO, but did not release a reference to the module. Need to check code paths for this to see where the reference needed to be released.

*known bug*

strxns 001. 2007-04-02T11:52:59+0000

ldl was not demand loading for 2.6 kernels due to missing MODULE_ALIAS declarations. Also, ldl had an incorrect SVR 3 style ‘MKDEV(MAJOR(*devp), i)’ construct in it that was using Linux utilities instead of Linux Fast-STREAMS utilities, causing the Stream head to attempt to redirect the major device. Unfortunalely, this was failing. Changed to the correct SVR 4 style ‘makedevice(getmajor(*devp), i)’. (There must still be a bad major redirection path in the Stream head.)

*fixed* in strxns-0.9.2.6

streams 008. 2007-03-31T05:33:29-0600

When loosening SMP locking, found a bug in the QWANTR handling in getq(9) and back-enabling in flushq(9) and flushband(9). Both of these were generating false back-enables. The getq(9) was generating a lot of false back-enables. Whenever getq(9) found an empty queue it was not only setting QWANTR, but it was back-enabling the queue. The result is that if service procedures are used exclusively (that is, qi_put(9) always does a putq(9)), getq(9) would generate a false back-enable for each message. Also, the enabled queue would generate another false back-enable. Significant performance gains should be noticed.

*fixed* in streams-0.9.2.3

streams 007. 2007-03-16T17:33:20-0600

strss7 003. 2007-03-13T02:40:38-0600 (x400p-ss7/5766)

It appears that V401PE cards were almost loading (configuring, mapping, downloading firmware) but were failing to configure at the final stage of the process (matching device id to board type). The device id for the 2155 is supposed to be b4 regardless of E1 or T1, but I just guess that the card is reporting 34 instead of b4 for E1 (it might be the firmware setting or unsetting the high bit as was done for the other devices). I changed the sl_x400p.c driver to print error messages when loading if such mismatches occur and set the device ids to accept 0x3X as an E1 2155 device and 0bX as a T1/J1 2155 device (even though they are all the same).

As it turns out, the V401PE cards have a DS2156 chip instead of a DS2155 chip. The only difference is the lack of Tx fixed gain control (register 0x7d) and the DS2156 supports a UTOPIA II bus that is not used on the V401PE. I changed the driver to recognize the DS2156 and skip register 0x7d when it exists. The DS2156 chip will work for both V401T (D33D) and V401E (D44D) cards.

*fixed* in strss7-0.9a.6

strsctp 003. 2007-03-10T05:59:10-0700

One serious locking problem discovered. sctp_cleanup_read(9) was suppressing IRQs across calls to putnext(9) when delivering data and acknowledgements. Recent kernels on Fedora and Ubuntu were complaining about IRQs suppressed across calls to local_bh_enable(9) in M2PA and that is what lead to the discovery.

*fixed* in strsctp-0.9.2.7

strtty 001. 2007-03-09T15:31:23-0700

The package was installing /dev/ptmx and /dev/pts/n device and removing them when uninstalling. This caused havoc with Linux’s UNIX’95 pseudo-terminal devices. They have been strapped out until later.

*fixed* in strtty-0.9.2.2

sigtran 001. 2007-03-08T21:09:59-0700

The inital timeout values associated with a freshly pushed M2PA module were being set to HZ based values instead of milliseconds. This did not affect the test program (which explicitly sets the values), but could have affected applications programs on systems where the tick clock is 100 Hz.

*fixed* in sigtran-0.9.2.2

strss7 002. 2007-03-08T21:05:47-0700

Timers were message up (using HZ instead of milliseconds) on the X400P driver. This did not affect architectures with 1000 HZ or 1024 HZ tick clocks, but 100 HZ systems object.

streams 005. 2007-03-07T15:53:06-0700

Demand loading of kernel modules for clone devices opened, for example, as /dev/streams/clone/mux was requesting module streams-clone-mux and /dev/streams/clone/mux but was not requesting streams-mux or /dev/streams/mux and the modules were failing to demand load.

*fixed* in streams-0.9.2.2

strss7 001. 2007-03-05T15:58:14-0700

For some reason the package was always building and installing the libxnet texinfo document which was keeping the RPM from installing after the strxnet package. This was fixed in doc/manual/Makefile.am with the addition of a ‘WITH_XNET’ conditional.

*fixed* in strss7-0.9a.6

strinet 002. 2007-03-05T01:24:13-0700

RPMs built on 2.4 kernels have using the ‘%dev’ construct for RPM instead of installing devices using the init scripts. RPM complains loudly because the dev package defines some of the same iBCS devices (e.g. /dev/ipip) as we are attempting to install. In the meantime, use –force.

Fixed in strinet.spec to never build devices ala rpm for strinet package.

strnsl 001. 2007-03-05T01:21:21-0700

RPMs built on 2.4 kernels install the ‘include strnsl’ line to modules.conf when there is no such directory installed by any of the rpms. This means that depmod complains loudly about the missing directory. This was fixed for the current release.

streams 004. 2007-02-26T08:25:09-0700

Jérémy Compostella pointed out error in clone.c. When an automatic clone minor device was unregistered, it was unregistering the modid instead of the major number. This was not noticed because all OpenSS7 drivers have the same modid as major number (strconf does this automatically).

A bug in the mi_copyout(9) function was discovered by inspection. The function should complete the last stage of a non-TRANSPARENT input-output control operation by returning an M_IOCACK(9) message, but did not. This was fixed for release 0.9.2.5.

test-sctp_n -o 9.2 Sun, 29 Oct 2006 16:27:35 -0700

When the number of test packets is set to 300, we are crashing on high speed SMP HT box. This seems to be a locking problem of sorts, or some flow control race condition. For now, the number of test packets, TEST_PACKETS has been reduced from 300 to 30 to avoid the crash. Again, packet tests at IP level should reveal this problem.

Note that there does not seem to be a problem with similar TPI tests, so the problem might be NPI interface related after all.

strsctp test-sctp_n -o 7.1 Sun, 15 Oct 2006 06:22:05 -0600

I notice that when the message size in this test is larger than the receive window size on the receiver, the receiver aborts the association after its window fills. If the message size is reduced to just beneath the receive window size, the test case succeeds. So, it looks like we are not handling zero window probes very well at all. For now I have just reduced the message size as this is for interface testing not packet testing. Packet tests at IP level should reveal this problem.

streams 002. 2006-09-24T20:02:00+0000

Discovered asynchronous thread cancellation inconsistencies in libLiS libpLiS by inspection during documentation. isastream(2s), fattach(2) were not performing proper asynchronous thread cancellation suppression so that these function contained a cancellation point when the should not.

Fedora Core 5 reports a rwlock bug during udp module unloading as follows:

It appears that unregister_strnod(9) is scheduling while holding a write lock on cdevsw_lock. This is probably in iput(9) called within cmin_del.

*fixed* in streams-0.7a.6.rc2

There were a number of places where sleeping functions were called with spin-locks held, causing the CPU awaking from the sleep to sometimes be different from the CPU that took the lock. This was buggy, so I reworked all of these cdev and fmod sections to handle spin locks properly. FC5/SMP on HT no longer reports these bugs.

strinet 001.

Several test cases are failing sending messages. ICMP port unreachable errors are resulting. It appears that the caching of destination addresses is somehow making the receiver think that it is a connection-oriented stream!


7.6 Schedule


Current Plan

Current Plan

The OpenSS7 package is a mature collection of all of the OpenSS7 STREAMS and protocol modules that builds all components on a wide range of supported Linux distributions and kernels. The OpenSS7 package is a builds and validates all components against a given distribution.

Therefore, the current plan for packaging is largely a maintenance plan. The OpenSS7 Project intends to release regularly new versions of the package that build and validate against upcoming releases of the supported Linux Distributions available from major distributors and upcoming releases of the Linux kernel, both mainline and as patched by major distributions. This release schedule is approximately every 3 to 6 months. More recent corrections and support for new distributions and kernels can be obtained by sponsoring the OpenSS7 Project and obtaining access to the live CVS repository (also available as a git repository).

Two significant plans for the package include providing cross-compiling support for more cross-platform development distributions, such as the Denx ELDK. Also, support for real-time distributions such as Montavista Linux and RT releases of SuSE and RedHat are within the scope of the development plan.

No additional components are currently planned although development within the existing components are planned. See the section for the component below, for a current development plan for a specific component.


STREAMS Current Plan

STREAMS Current Plan

There are not many things left to be done on the production Linux Fast-STREAMS component. As of the streams-0.9.3 release, performance modifications are complete. The component now exhibits performance on STREAMS-based pipes and TPI drivers that is significantly (factor of 2 or more) superior to that experienced by legacy Linux facilities.

Therefore, the current plan for Linux Fast-STREAMS is largely a maintenance plan. Items on the todo list, below, will be picked up as time permits. The OpenSS7 Project intends to release regularly new versions of Linux Fast-STREAMS that build and validate against upcoming releases of the supported Linux Distributions available from major distributors and upcoming releases of the Linux kernel, both mainline and as patched by major distributors. This release schedule is approximately every 3 to 6 months. More recent corrections and support for new distributions and kernels can be obtained by sponsoring the OpenSS7 Project and obtaining access to the live CVS repository (also available as a git repository).

One development activity in the works for Linux Fast-STREAMS is to provide integral support for more embedded cross-platform development systems such as the Denx ELDK, as well a existing and emerging RT kernels such as Montavista and the upcoming SuSE and RedHat RT kernels. This is a significant undertaking and will only be embarked upon when the OpenSS7 Project is given free access to these RT kernels and distributions.


COMPAT Current Plan

COMPAT Current Plan

There are not many things left to be done on the production OpenSS7 STREAMS Compatibility Modules component. The current plan for the component is largely a maintenance plan including support for current distributions and kernels.

There are currently a large array of Solaris DDI compatibility functions that are not implemented; however, there have not been many requests for this capability. Perhaps the advent of OpenSolaris has forstalled porting of many drivers to Linux, but, regardless of the cause, there is just not a demand. If there are any functions that you need the OpenSS7 Project to support that are not currently supported in one of the compatibility modules, please request support for them on the openss7-develop mailing list.


BCM Current Plan

BCM Current Plan

The OpenSS7 Project has made several stabs at making this component available and providing it in a production grade form. All attempts are currently incomplete. All in all there does not appear to be sufficient interest in this capability to actually fund the work. Therefore, this component will remain incomplete until some entity can justify funding the remainder of the development. The OpenSS7 Project remains committed to the open source model and providing this support runs somewhat against that. However, if your organization has a pressing need for this capability and can offer funding for its completion, please contact the project on the openss7 mailing list.


TTY Current Plan

TTY Current Plan

This component is still incomplete. It is missing a fully functional ldterm module. Also, performance testing of STREAMS-based pipes from the Linux Fast-STREAMS indicates that STREAMS-based pseudo-terminals could exhibit far superior performance to that exhibited by the legacy Linux (SVR 3 style) pseduo-terminals. To accomplish this requires fully implementing ldterm, creating validation test suites, and peformance analysis and comparison with legacy Linux mechanisms.

This component is not currently a priority for the OpenSS7 Project, which is focussed on more telecom-specific protocol stacks and capabilities. Nevertheless, if completion of this component is important in your industry and your organization is able to fund further development or contribute the missing items, contact us on the openss7-develop mailing list. Until funding or a mandate surfaces, this component will likely continue as a proof-of-concept only. It will be maintained in a compilable and installable state (that is, it will be updated for current Linux distributions and kernels) on the same basis as other components in the OpenSS7 package.


CHAN Current Plan

CHAN Current Plan

This component, which contains hard-switch or MG capabilities is not currently planned. Of priority is the production deployment of soft-switch or MGC and Signalling Gateway components from the SIGTRAN, SS7 and VOIP components. This component will only receive maintenance releases until those priorities have been sufficiently met (over the course of Summer 2009).


XNS Current Plan

XNS Current Plan

This component is mature and complete and in production release. The current plan is to provide only maintenance releases supporting more recent Linux distributions, kernels and tool chains as they evolve. Expect public maintenance releases on a 3 to 6 month cycle.


XNET Current Plan

XNET Current Plan

This component is mature and complete and in production release. The current plan is to provide only maintenance releases supporting more recent Linux distributions, kernels and tool chains as they evolve. Expect public maintenance releases on a 3 to 6 month cycle.


NSL Current Plan

NSL Current Plan

Current plans are to just maintain this component for recent distributions, kernels and tool chains. Although at some point the relation of this component to TI-RPC 2.8 needs to be worked out, when that will happen is not currently on a schedule. I do not really know how much of a requirement there is for ONC RPC running over other transports such as ISO transports and SCTP transports, although it would surely be interesting to run NFS4 over SCTP.

This component is not currently a priority for the OpenSS7 Project, which is focussed on more telecom-specific protocol stacks and capabilities. Nevertheless, if completion of this component is important in your industry and your organization is able to fund further development or contribute the missing items, contact us on the openss7-develop mailing list. Until funding or a mandate surfaces, this component will likely continue as a proof-of-concept only. It will be maintained in a compilable and installable component (that is, it will be updated for current Linux distributions and kernels) on the same basis as other components in the OpenSS7 package.


SOCK Current Plan

SOCK Current Plan

This component is still incomplete. It is missing a fully functional Stream head socket library, module or driver implementation. Also, performance testing of STREAMS INET drivers indicates that STREAMS-based networking components could exhibit far superior performance to that exhibited by legacy Linux sockets. To accomplish this requires fully implementing socklib(3), sockmod(4) module or socksys(4) driver, creating validation test suites, and performance analysis and comparison with legacy Linux mechanisms.

X25 Current Plan

X25 Current Plan

This component was initially started to provide managment interfaces to platforms using the OpenSS7 protocol stacks (CMIP and CMOT interfaces) using SS7 GDMO and other GDMO. It was considered pulling some of the old isode package into this component to provide some GDMO facilities.

Since then, it was discovered that these ISO protocols are still very important to a number of industries on Linux and Linux Fast-STREAMS. These industries are the Aviation and Financial industries. Closer to the heard of telecommunications is the applications of aircraft to ground communications for the Aviation industry.

While the OpenSS7 Project’s focus over the Summer of 2009 is going to be soft-switch enabling protocols, that may change if the Aviation industry steps up to this component with some funding to complete the work or by contributing changes, improvements or development to this component. Otherwise, expect this component to receive only maintenance releases over the next 8 months or so.

ISDN Current Plan

ISDN Current Plan

This component is lower down on the priority list. Current focus is on pushing through the SIGTRAN, SS7 and VOIP components instead. This components sits at about the same status as the CHAN component. there exists modules and drivers in this component that have not yet been publicly released and are only available to sponsors of the OpenSS7 Project on the CVS archive. When the project gets back to this component (sometime 2H2009), the plan will be to move the private modules and drivers into the public release, place conformance validation test cases around them and release this component as production grade.


SS7 Current Plan

SS7 Current Plan

The current plan includes the public production release of SCCP, ISUP and TCAP components. MTP3 has not yet been publicly released and is not currently scheduled. (Implementing the AS-side of M3UA is taking precedence.) The first public production releases of SCCP, ISUP and TCAP are planned for the end of July 2009. This will be followed by lab and limitied field trial testing with a lead customer in August and production deployment in the lead customer’s network in 1Q2009. Expect that over the next 8 months releases of this component will include major new development and validation testing as well as including SCCP, ISUP and TCAP components that have nor heretofore been publicly released.


SIGTRAN Current Plan

SIGTRAN Current Plan

The current plan of the next several months (over the summer of 2009) is to actively move this component forward. This consists of the following:

  • Move SIGTRAN modules and drivers that have not yet been publicly released into the public release.
  • Write test cases for complete AS-side implementations of all of the UAs (including ISUA and TUA).
  • Perform production testing of the UAs against Tekelec Eagle and Cisco ITP equipment.
  • Rigorous lab and limited field testing of AS-side components.
  • Production deployment in customer’s network for 1Q2009.

Note that M2PA is complete. Aside from that, the order of testing and implementation will be M3UA followed by M2UA or SUA and then TUA, IUA (including V5UA and GR303UA) and ISUA.

Production public releases of the AS side of M3UA can be expected by the end of July 2009.


ATM Current Plan

VOIP Current Plan

VOIP Current Plan

The current plan of the next several months (over the summer of 2009) is to actively move this component forward. This consists of the following:

  • Implementation and testing of MGCP (MGC-side) using the MGI and TCP transport from the INET component.
  • Implementation and testing of MEGACO/H.248 (MGC-side, binary format) using the MGI and SCTP transport from the SCTP component.
  • Implementation of SIP-T and SIP call control using the CCI and TCP transport from the INET component and later SCTP transport from the SCTP component.
  • Perform production testing of MEGACO/H.248 and MGCP against the Veraz iGATE, the Cisco 5400 and the Sonus Media Gateways.
  • Rigorous lab and limited field testing of the MGC-side components.
  • Production deployment in customer’s network for 1Q2009.

The order of testing will be MEGACO/H.248 and then SIP-T and SIP followed by MGCP. Production public releases of the MGC side of MEGACO/H.248 and SIP-T acan be expected by the end of July 2009.


Things to Do

Things to Do

  • - Packaging.

    Get master build package working better. Currently the master build package does not build a master tarball or RPM distribution, which would be nice, only individual RPMs for subpackages.

  • - Cross-testing framework.

    We have nice autotest test suites that are fine for native builds, but for cross-compile builds, it would also be nice to cross-test. We can accomplish this nicely within the autoconf framework using DejaGNU. DejaGNU configured under the STREAMS, but we need a more general autoconf .m4 fragement check for the existence of DejaGNU, and automake and DejaGNU expect wrappers for the existing test programs (and integration into the make check-DEJAGNU target). Then we could cross-build the package and then execute the test scripts on the result on a remote board using DEJAGNU.

  • - Distributed testing framework.

    Because these are mostly communications protocols implemented using STREAMS, it is important to be able to do consistent distributed testing and validation of the protocol implementations. We can perform much validation using Ferry-Clip approaches (linking or pushing STREAMS-based pipes beneath drivers or modules), however, acceptance and performance testing would benefit from a distributed framework. Perhaps the most direct yet general approach to this is TETware from OpenGroup and is used for POSIX (and XNS 5.2, by the way) test suites from OpenGroup. Although netperf incorporates its own client-server subsystem, TETware provides these mechanisms separately. TETware also provides mechanisms for test case synchronization points between distributed systems that makes distributed conformance test cases quite possible. Note that TETware does not really require any external tools but does require network access and installation on the target systems (unlike DejaGNU that can execute test cases over a serial port if necessary).

  • - Dynamic configuration.

    Automake files (Makefile.am) are too static. The strbcm package needs the list of sources and objects to be rather dynamic. It would be nice to convert all packages to the same approach. We could perhaps use strconf-sh to generate Makefile.in fragments at configuration time and then include them in a far more general main Makefile.am file.

  • - Merge sub-packages.

    I really want to put all these packages back together, it is too time consuming maintaining the various administrative files for each of seven or so packages.

    • streams-0.7a.5
    • strcompat-0.9.2.4
    • strutil-0.9.2.4
    • strxns-0.9.2.4
    • strxnet-0.9.2.9
    • strinet-0.9.2.4
    • strsctp-0.9.2.6
    • netperf-2.3.2

    The result will be just a streams-0.9.4 release. The only two (STREAMS) packages left will be strbcm and strss7.


STREAMS Things to Do

STREAMS Things to Do

  • - Support for RT kernels. This is a little more than just having the STREAMS scheduler run as a non-RT process kernel thread, which it does now, and which is trivial. (The existing package should compile and run against these kernels with minor modification in this event.)

    More to the point is working the light-weight STREAMS scheduler and service procedures into a prioritized scheme where service procedures run as real-time, yet pre-emptable tasks. In contrast to the current scheme, it is likely that the approach would be to either spawn multiple kernel threads for the STREAMS scheduler at different priorities, or to alter the priority of the STREAMS scheduler in response to the scheduling of specific queues at specific priorities. A design is not really possible until the intricacies of upcoming RT kernels are discovered.

    TODO:

    Provide support for RT kernels.

  • - Per cpu data:- I am still using the older approach of using cache line aligned arrays for per-cpu data. This, of course, does not fully utilize NUMA architectures. For NUMA architectures we need to use the per-cpu utilities provided by the 2.6 and 3.x kernel. I haven’t touched converting this yet.

    Also, there are several NUMA supporting STREAMS utility functions (allocb_node, etc.) that need to be supported yet.

    TODO:

    Convert cacheline aligned arrays to NUMA per-cpu data on 2.6 and 3.x kernels. Complete NUMA supporting STREAMS facilities.

  • - Provide support for assigning a processor affinity for queue pairs. The current STREAMS scheduler will schedule a queue enabled as a result of, for example, a put() on the same processor that performed the action that caused the enable. This has been adequate for event driven systems. However, for pipelined hard real-time, better processor instruction cache efficiency and concurrency might be gained by assigning portions of the pipeline to different processors, so that, for example, when a put is performed to a queue, that the queue will become enabled against the process with which it has an affinity rather than the enabling processor. This might permit assigning a different processor affinity to each queue-pair in a pipeline to exploit concurrency in the pipeline.
    TODO:

    Add an optional processor affinity to the STREAMS scheduler.

  • - Split include/sys/streams/stropts.h by architecture. There is conflicting numbering on the standard STREAMS input-output controls:
    I_SWROPT(7)I_GWROPT(7)I_LIST(7)
    I_FLUSHBAND(7)I_CKBAND(7)I_GETBAND(7)
    I_ATMARK(7)I_SETCLTIME(7)I_GETCLTIME(7)
    I_CANPUT(7)

    System V Release 4 UNIX® vendors use one set and OSF UNIX® vendors use another. Namely HP-UX, OSF/1.2, AIX, Mac OpenTransport use OSF numbering, whereas IRIX, Solaris, UnixWare and others use SVR4 numbering. So, for HPPA, Alpha, PowerPC, we should use the OSF numbering.

    I know that it is a fall-back to the SVR4 way of separating architectural differences by UNIX vendor (if it is HPPA, it must be sold by HP and it must be HP-UX running on it, for example), but even the Linux kernel is victim to this (many ioctls and some errno numbering is split this way). It is completely entrenched in GNU autoconf’s config.guess.

    TODO:

    Split include/sys/streams/stropts.h by processor architecture.

  • - A similar numbering mismatch occurs for many of the message block types.
    TODO:

    Split include/sys/streams/streams.h by processor architecture.

  • - Implement I_EGETSIG(7) and I_ESETSIG(7). These are Solaris enhanced version of the I_GETSIG(7) and I_SETSIG(7) STREAMS input-output controls. The difficulty with their implementation is that the entire signal handling setup inside the Stream head code is geared toward the calling process and needs to be adjusted to be general enough for any process or process group. Until then, Linux file asynchronous I/O is supported.
    PARTLY DONE:

    Wrote the manual pages and added them to the build. Placed function skeletons that return [EOPNOTSUPP] for these functions in the Stream head.

    TODO:

    Implement I_EGETSIG(7) and I_ESETSIG(7).

  • - Socket buffer handling:
    1. Rather than write offset and padding, why not provide a flag (e.g. SO_SKBUFF) to indicate to the stream head to allocate an sk_buff with the message block and share buffers between mblk and sk_buff, then, the sk_buff can be used without allocation in the bottom half. esballoc() and alloc_skbuff() can be used to set up the message block. dup() could be made aware of the hidden sk_buff and increment the shared sk_buff count as well. Also, msgpullup() and pullupmsg() could be made aware of message blocks containing sk_buffs and have them do the appropriate thing.
    2. The other thing that is needed is some way to tell the other end of a loopback connection that the sk_buff it has received already has an mblk attached to it as above. Then the message block could be simply passed upstream and one would not need to be esballoc’ed for it.
    3. Another thing is to provide the ability to partial checksum and copy data from user into these sk_buffs, but setting an SO_CSUM flag along with the SO_SKBUFF flag to indicate the type of checksum to perform.

    The combination of the above three items should provide some serious performance gains for Linux networking based stream heads.

    PARTIALLY DONE:

    Item (1) is done and complete. The 2nd generation UDP and RAW drivers are already using it. Item (2) and (3) remain.

  • - Had another look at specfs, devfs and udev. It looks like we can create minor device nodes within /dev (not just /dev/streams) using devfs or udev. Again, this doesn’t do everything that specfs does. specfs will demand load when an attempt is made to open a non-existent character device. Nevertheless, we can describe a "streams" class for udev and when a module registers a minor device node, we can have udev create that device node and provide permissions by adding our files to the /etc/udev/rules.d and /etc/udev/permissions.d directories.

    Therefore, on a udev system, we should make strconf-sh create the necessary rules.d and permissions.d file entries. register_strnod will be modified to create a udev instance within the stream class matching the rules.d and permissions.d entry when creating a minor device node within the specfs.

    On a devfs system, register_strdev and register_strnod should perform devfs calls instead of calling register_chrdev. That way minor device nodes will automatically appear at least once the module is loaded.

    TODO:

    rationalize specfs to devfs and udev

  • - Have the STREAMS subsystem register a panic notifier on 2.6 and 3.x kernels to be able to recover from panics caused by misbehaving STREAMS modules or drivers.
    TODO:

    Register panic notifier.

  • - Kernel objects are another thing. For 2.6 or 3.x kernels, we need to hold our data structures in the kobject manner so that the /sys file system is usable. This requires another adaptation layer because 2.4 kernels do this in a completely different way. Much of our /proc file system stuff needs to move into /sys for 2.6 or 3.x kernels but stay the same for 2.4 kernels.

    The /sys file system does not really do much for STREAMS. The /dev/streams specfs file system does more for us.

    SKIPPED.

COMPAT Things to Do

COMPAT Things to Do

  • - Implement the AIX strtune() command.

    *todo*

  • - I would really really like a set of rmallocmap(), rmalloc(), rmalloc_wait(), rmfree(), rmfreemap() functions so that drivers could stop using the kmem_cache functions but could acheive similar effect.

    *todo*

  • - Work in MUTEX_ALLOC(), MUTEX_DESTROY(), MUTEX_LOCK(), MUTEX_MINE(), MUTEX_OWNED(), MUTEX_TRYLOCK(), MUTEX_UNLOCK() from IRIX into irixcompat.c.

    *todo*

  • - Work in streams_interrupt() and STREAMS_TIMEOUT() from IRIX into irixcompat.c.

    *todo*

  • - Hey, here’s an idea for testing Solaris compatibility: take an OpenSolaris source file for a STREAMS driver and compile and test it under Linux with no (or minimal) source code modifications!

    *todo*

  • - Write test programs and test suites. There are really not any test programs or test suites available for the OpenSS7 STREAMS Compatibility Modules package as of strcompat-0.9.2.2.

    *todo*

  • - Not all compatibility functionality is implemented. There are a large number of Sun DDI functions applicable to STREAMS that have not been fully implemented. Also, the Sun configuration management mechanism is not yet fully implemented and neither is that for AIX. Also, there is a large group of SVR 4.2 compatible functions that are not directly STREAMS related but are part of the DDI/DKI and should be implemented to provide abstraction from Linux internals as well as the ability to link binary modules.
    *moved*

    (Note that the ability to link binary modules has been moved to is own strbcm package.)

  • - Linking of binary modules is not yet supported. This is the place (strcompat) where binary modules should be permitted to be loaded against Linux Fast-STREAMS, because the binary compatibility interface modules are defined here. There is the beginnings of an strconf script output to generate a C-language wrapper file that will link with a binary object file to generate a loadable module that could load under Linux Fast-STREAMS.
    *moved*

    (Note that the ability to link binary modules has been moved to is own strbcm package.)

  • - Documentation. The documentation is trailing a bit. I have thousands of manual pages written, however, some are sparse or incomplete. Also, the manual and the STREAMS Porting Guide needs a bunch of work.
    *todo*

    Did a bunch of work on the manual, however, there is still a lot of work on a STREAMS Porting Guide to be done.


BCM Things to Do

BCM Things to Do

  • - Testing. This package is completely untested. One way to test compatibility is to take a set of frozen binary modules and drivers from the release and place them in a test directory.
  • - The strbcm package is currently incomplete. The purpose of the package was to move STREAMS binary compatibility module capabilities outside of the STREAMS release package. As Linux Fast-STREAMS has become production grade in terms of both performance and conformance, it is no longer necessary to keep these packages separate and they can be combined once again (or still) with Linux Fast-STREAMS.

    This package; however, might has some use still outside of Linux Fast-STREAMS if only because it provides a separable way of incorporating 3rd party binary modules.


TTY Things to Do

TTY Things to Do

  • - Testing. This package is completely untested.

    *todo*

  • - Create a library libtty(3) to hold the library functions for use with this package:
    openpt(3)
    grantpt(3)
    ptsname(3)
    unlockpt(3)

    *todo*

  • - Create an ldterm(4) Line Discipline for Terminals STREAMS module. This item remains to be done. Al that is in place right now is a skeleton module.

    *todo*

The openss7 package is currently incomplete.

The purpose of the package was to provide STREAMS terminal capabilities for Linux Fast-STREAMS. The package will only build and install with Linux Fast-STREAMS

If someone is interested in this package, a contribution of a working ldterm(4) module would be good. Also, testing could be performed.


CHAN Things to Do

CHAN Things to Do

  • - Testing. This package is completely untested.

    This remains to be done.

  • - Actually implement all of the package.
  • - Copy all of the channel drivers, multiplexers and switching drivers as well as media gateway drivers from the strss7 package and place it here.

    Note that this package should load before the strxns package because it provides channels that can be used for hdlc links and data links and the strxns package provides the CDI and DLPI interfaces. It is possible that the CDI interface should be moved here.


XNS Things to Do

XNS Things to Do

  • - I want to write a NetFilter pseudo-device driver that will install and control netfilter hooks for performance testing. It will do things like packet drops, checksum errors, packet duplication, packet delay, and combinations, for a specified range of addresses and/or protocols. Also a set of user-space utilities (C language programs) to permit the control of the filters. The purpose is to be able to do a wide range of performance testing on simulated networks that are simply loop back devices. This would permit performance test programs (such as netperf) to be used for testing special network conditions on SCTP (for example), and will also allow for comparison tests.
  • The strxns package contains several GPL’d modules and drivers originally included in the STREAMS releases that were removed to this package so that they could be used with Linux Fast-STREAMS.
  • - Test. Almost none of the modules or drivers in this package have been tested thoroughly against Linux Fast-STREAMS. One of the primary reasons for this is that The OpenSS7 Project does not really use any of these modules or drivers.
  • - This might be a useful place to drop all of the DLPI drivers from the strss7 package, particularly those for X.25, Frame Relay, and ISDN LAPD and LAPB.

XNET Things to Do

XNET Things to Do

  • The texinfo manual, libxnet.texi, is incomplete. For the time being, the manual pages, starting with libxnet(3), are the definitive documentation. It would be nice to also provide these library manual pages as a printable manual, however, the project has not yet found the time to complete this manual.

    *todo*

  • There is an XTITRACE option the was associated wtih the XTI library that provided the abilty to record trace information to a temporary file and then display or print it with an xtitrace user program. This capability is not yet implemented in this XTI library and remains to be done.

    *todo*

  • Need to remove the following functions: t_sndopt(3), t_sndvopt(3), t_rcvopt(3) and t_rcvvopt(3); as they are non-standard and non-portable. Instead use the following functions: t_sndudata(3), t_sndvudata(3), t_rcvudata(3) and t_rcvvudata(3); because they have precisely the same argument templates as the other. These functions are described in the OpenGroup documentation as inapplicable to connection-oriented transports, however, we could relieve that restriction for SCTP. The characteristics to check is if T_CLTS, okay, T_COTS or T_COTS_ORD, only okay if the tsdu_size is not T_INVALID (as it is for TCP). (It would be okay to be T_INFINITE as it is for SCTP.)

    *todo*

    They may have already been removed. Verify this. They certainly have to be implemented this way yet.

  • The XTI/TLI library is now largely in maintenance mode. Not much special development is planned.
  • - Full ATM Support. This is an item where the XTI implementation is lacking. When we provide full TPI ATM support under the strss7 package, then this item will be investigated.

    *todo*


NSL Things to Do

NSL Things to Do

  • Fedora 7 has a libtirpc library that uses the /etc/netconfig files. To avoid conflicts, the installation scripts now avoid overwriting this file. An interesting thing is that the libtirpc implementation is taken from TI-RPC 2.3 when there is a TI-RPC 2.8 available. In generating an strrpc package, it should replace this broken libtirpc library with a TI-RPC 2.8 library supporting STREAMS using this strnsl package.

    *todo*

  • The package still needs to be internationalized.

    *todo*

  • This implementation of the Network Selection facility and Name-to-Address mapping allows direct use of TI-RPC for Linux. The primary benefit of this is the ability to use TI-RPC code directly without significant and thus support upper level services such as NFS Version 4. Another amazing possibility is to not only immediately run NFS Version 4, but also to run it over SCTP. A todo item is to take the TI-RPC 2.8 release and port it to Linux Fast-STREAMS. This might best be approached with a separate strrpc package, or addressed directly by this package.

    *todo*

  • The texinfo manual, libxnsl.texi, is incomplete. For the time being, the manual pages, starting with libxnsl(3), are the definitive documentation. It would be nice to also provide these library manual pages as a printable manual, however, the project has not yet found the time to complete this manual.

    *todo*

  • This package is largely untested. A conformance test suite and some test cases need to be written.

    *todo*


SOCK Things to Do

SOCK Things to Do

  • - Testing. This package is completely untested.

    *todo*

  • - Create a socksys(4) Socket System STREAMS driver.

    *todo*

  • - It would be interesting to perform some Netperf and Iperf performance tests against STREAMS-based network drivers supporting Transport Provider Interface (TPI) and Sockets using this socket system. Without sockmod(4) and libsocket it was only possible to use Netperf for performance testing, and then only using the XTI tests.

    *todo*

  • - Create the socket(3) libsocket shared library.

    *todo*

  • - Create a sockmod(4) Socket Module STREAMS module.

    *todo*

  • - Move already written code from the stacks or strss7 directories into the src directory.

    *todo*

The openss7 package is currently incomplete.

The purpose of the package was to move STREAMS socket capabilities outside of the STREAMS release package. As Linux Fast-STREAMS has already shown production grade in terms of both performance and conformance, it is no longer necessary to keep these packages separate and they can be combined once again (or still) with Linux Fast-STREAMS.


INET Things to Do

INET Things to Do

  • - Loop back devices (ticlts, ticots, ticotsord) are currently implemented in the inet(4) driver using UNIX domain sockets and the XTI over sockets approach. It should be straightforward to implement these loopback devices directly in STREAMS without involving sockets. These second generation loopback drivers need to be written yet.

    *todo*

  • - Implement pseudo-connection oriented modes in INET(4) driver as well as udp2(4) and rawip2(4) drivers. Document use of pseudo-connection oriented modes for UDP and RAWIP. Pseudo-connection oriented modes permit a connectionless (T_CLTS) provider such as udp to provide the appearance of connection oriented service. This makes conversion from the Sockets API to XTI API easier.

    Note that this is also very applicable to MTP (quasi-associated signalling such as ISUP) and SCCP protocol class 0 and 1 and TCAP.

    *todo*

  • - It might be worth retrying the netperf(1) performance test on the second generation UDP driver with this pseudo-connection oriented mode in place. You see, the netperf tests for UDP sockets performs a connect(3).

    *todo*

  • - Implement pseudo-connectionless modes in INET(4) driver as well as sctp(4) drivers. Document use of pseudo-connectionless modes for SCTP (not really applicable to TCP). Pseudo-connectionless modes permit a connection-oriented (T_COTS) provider such as sctp to provide the appearance of connectionless service. This makes support for the SCTP one-to-many model easier. Also, it provides a way (t_sndudata(3), t_sndvudata(3), t_rcvudata(3), t_rcvvudata(3)) of passing options associated with the packet to the provider either in a T_OPTDATA or in a T_UNITDATA. This would make support of SCTP’s many per-packet options more workable for XTI as well as providing a easier translation between the sockets API and XTI API for sctp.

    Note that this is also very applicable to SCCP protocol classes 2 and 3 and BSSAP.

    *todo*

  • - Convert inet driver to use os7 common functions. In fact, it might be a better idea to convert the driver to use MPS common functions instead as we are now trying to move away from os7 common functions.

    *todo*

  • - Connectionless testing using netperf competes well with connection-oriented sockets. Need to still modify netperf to use (pseudo-)connection-oriented UDP for better comparison.

    *todo*


SCTP Things to Do

SCTP Things to Do

  • - The strsctp package is quite stable and mature as of strsctp-0.9.2.2 and most of the things that remain to be done are rigorous conformance and performance testing.

    *todo*

  • - Move the tpiperf(4) module to the strxnet package and rename it tiperf(4).

    *todo*

  • - Implement pseudo-connectionless modes in sctp(4) driver. Document use of pseudo-connectionless modes for SCTP. Pseudo-connectionless modes permit a connection-oriented (T_COTS) provider such as sctp_t(4) to provide the appearance of connectionless service. This makes support for the SCTP one-to-many model easier. Also, it provides a way (t_sndudata(3), t_sndvudata(3), t_rcvudata(3), t_rcvvudata(3)) of passing options associated with the packet to the provider either in a T_OPTDATA or in a T_UNITDATA. This would make support of SCTP’s many per-packet options more workable for XTI as well as providing an easier translation between the sockets API and XTI API for sctp.

    Note that this is also very applicable to SCTP protocol classes 2 and 3 and BSSAP.

    Perhaps the first proper step for this is to rewrite t_sndudata(3), t_sndvudate(3), t_rcvudata(3), and t_rcvvudata(3) handle T_OPTDATA_REQ(7) and T_OPTDATA_IND(7) primitives when in T_COTS mode.

    *todo*

  • - Work recent SCTP I-G changes into the code. Many of the I-G changes over the years have been implemented in the code, however, some of the more recent changes that made it into RFC 4460 have not yet been added. This is an ongoing process.

    *todo*

  • - Writing new IP-packet-level conformance test suites.

    *todo*

  • - It would also be an idea to make the STREAMS SCTP Driver able to be pushed as a module over a STREAMS-based pipe end so that Ferry-Clip conformance testing could be performed. In fact, Ferry-Clip testing might be better and more flexible than IP-packet-level testing because it is possible to closely control the timing of arriving packets on a STREAMS-based pipe. In fact, this is such a good idea, I think that I will proceed along the Ferry-Clip lines for testing first and only perform the IP packet-level testing later.

7.7 History

For the latest developments with regard to history of changes, please see the ChangeLog file in the release package.


8 Installation

Please note that the installation instructions have changed. Previously OpenSS7 releases consisted of a number of subpackages to a master package: this is no longer the case. All OpenSS7 release software is now contained in a single package. This change was necessary to reduce the maintenance burden cause by a growing number of subpackages. The net benefit of this changes is that the resulting tarballs, RPMs and DEBs are far less error prone due to far fewer dependencies between RPMs and DEBs.


8.1 Repositories

The OpenSS7 package release can be accessed from the repositories of The OpenSS7 Project. For rpm(8) based systems, the package is available in a yum(8) repository based on repo-md XML and may also be accessed using up2date(8), zypper(8) or yast(8). For yast(8) based systems, the package is also available as a yast(8) installation source. For dpkg(1) based systems, the package is available in an apt(8) repository.

By far the easiest (most repeatable and manageable) form for installing and using the OpenSS7 packages is to install packages from the yum(8), yast(8) or apt(8) repositories. If your distribution does not support yum(8), zypper(8), up2date(8), yast(8) or apt(8), then it is still possible to install the RPMs or DEBs from the repositories using rpm(8), dpkg(1); or by using wget(1) and then installing them from RPM or DEB using rpm(8) or dpkg(1) locally.

If binaries are not available for your distribution or specific kernel, but your distribution supports rpm(8) or dpkg(1), the next best method for installing and using OpenSS7 packages is to download and rebuild the source RPMs or DSCs from the repository. This can also be performed with yum(8), zypper(8), yast(8), apt(8); or directly using wget(1), rpm(8) or dpkg(1).

If your architecture does not support rpm(8) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets or for development), the final resort method is to download, configure, build and install from the tarball.


8.1.1 Repository Access

Repositories are located under https://www.openss7.org/repo. The path from there to the specific repository consists of the following components:

packaging

For yum(8) and yast(8) repositories, this is always rpms. For apt(1) repositories, this is always debs. For tar(1) repositories, this is tarballs.

distro

The identifier of the distrbution. Example, centos, debian.

release

The release of the distribution. Example, 5.5, squeeze.

arch

The architecture of the release. Example , x86_64, amd64.

So, for example, the CentOS 5.5 distribution for x86_64 is located under https://www.openss7.org/repo/rpms/centos/5.5/x86_64/; the Debian Squeeze distribution for i386 is located under https://www.openss7.org/repo/debs/debian/squeeze/i386/; the tarball distribution is located under https://www.openss7.org/repo/tarballs.

Note that repository access is restricted. You may download the repo packages without restriction, however, when installing the repo package you will be prompted for your registration username and repository password. The RPMs or DEBs that you will be allowed access to will depend on your entitlement.

8.1.2 Repositories for YUM

The yum(8) repositories are based on repo-md XML and are provided for all RedHat/Fedora architectures RHEL 4.8 and beyond, or FC 7 and beyond. This includes all current (supported) RHEL systems.


8.1.2.1 Setting up YUM

To install or upgrade from the OpenSS7 repo-md repositories using yum(8), you will need to install the openss7-repo RPM on your system, as follows:

$> REPO="https://user@www.openss7.org/repo/rpms"
$> REPONOARCH="$REPO/fedora/15/x86_64/RPMS/noarch"
$> REPORPM="$REPONOARCH/openss7-repo.noarch.rpm"
$> sudo rpm -Uhv $REPORPM
$> Username: anonymous
$> Password: *******

The example, above, assumes that the distribution is ‘fedora’ and the distribution release is ‘15’ and the required architecture is ‘x86_64’. Another example would be $REPO/redhat/6.0/x86_64/RPMS/noarch, for using yum(8) with RHEL.

To obtain access to the repository at the level to which you are entitled, you will have to respond to the ‘Username:’ query with the user name with which you are registered with https://www.openss7.org/, and to the ‘Password:’ query with your repository access password.30

You can test whether the yum(8) repository is properly set up by refreshing the repository and by listing the packages:

$> sudo yum makecache openss7
$> sudo yum search openss7
$> sudo yum info openss7
$> sudo yum info @openss7

Note that only the packages to which you are entitled will be listed.


8.1.2.2 Using the YUM Repository

Once the repository is set up, OpenSS7 includes a number of virtual package and package group definitions that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is as easy as (one of):

$> sudo yum install openss7
$> sudo yum install @openss7
$> sudo yum groupinstall openss7

Removing the package is as easy as (one of):

$> sudo yum remove openss7
$> sudo yum remove @openss7
$> sudo yum groupremove openss7

To install the development packages for developing STREAMS modules and drivers, or applications that use the OpenSS7 Protocol Suites, install the development packages using (one of):

$> sudo yum install openss7-devel
$> sudo yum install @openss7-devel
$> sudo yum groupinstall openss7-devel

Of course, you are welcome to use a GUI based package manager, such as PackageKit(8).


8.1.2.3 YUM Kernel Updates

The OpenSS7 yum(8) repository definitions support the automatic updating of kernel modules when kernels are updated. When the system is updated, using ‘yum update’, openss7 packages that are available for an updated kernel will be installed automatically. OpenSS7 kernel module packages also support weak updates and when kernels are updated to compatible kernels (e.g. for security updates, or normally for any update within an Enterprise distribution), kernel modules are automatically applied against the updated kernel.


8.1.2.4 Setting up ZYPPER

To install or upgrade from the OpenSS7 repo-md repositories using zypper(8), you will need to install the openss7-repo RPM on your system, as follows:

$> REPO="https://user@www.openss7.org/repo/rpms"
$> REPONOARCH="$REPO/opensuse/11/x86_64/RPMS/noarch"
$> REPORPM="$REPONOARCH/openss7-repo.noarch.rpm"
$> sudo rpm -Uhv $REPORPM
$> Username: anonymous
$> Password: *******

The example assumes that the distribution is ‘opensuse’ and the distribution release is ‘11’ and the architecture requiresd is ‘x86_64’. Another example would be $REPO/suse/11/x86_64/RPMS/noarch, for using zypper(8) with SLES.

To obtain access to the repository at the level to which you are entitled, you will have to respond to the ‘Username:’ query with the user name with which you are registered with https://www.openss7.org/, and to the ‘Password:’ query with your repository access password.31

zypper(8) does not do a very good job of importing GPG signatures. When zypper is reporting that there are no keys for the RPMs being installed, the key can be imported directly into RPM as follows:

$> sudo rpm --import https://www.openss7.org/pubkey.asc

You can test whether the zypper(8) repository is properly set up by refreshing the repository and by listing the packages:

$> sudo zypper refresh openss7
$> sudo zypper search -t package openss7
$> sudo zypper info -t package openss7

8.1.2.5 Using the ZYPPER Repository

Once the repository is set up, OpenSS7 includes a number of virtual package and package group (pattern) definitions that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is a easy as (one of):

$> sudo zypper install -t pattern openss7
$> sudo zypper install openss7

Removing the package is as easy as:32

$> sudo zypper remove openss7

To install the development packages for developing STREAMS modules and drivers, or applications that use the OpenSS7 Protocol Suites, install the development packages using (one of):

$> sudo zypper install -t pattern openss7-devel
$> sudo zypper install openss7-devel

Of course, you are welcome to use a GUI based package manager, such as yast2(8).


8.1.2.6 ZYPPER Kernel Updates

The OpenSS7 zypper(8) repository definitions support the automatic updating of kernel modules when kernels are updated. When the system is updated, using ‘zypper update’, OpenSS7 packages that are available for an updated kernel will be installed automatically. OpenSS7 kernel module packages also support weak updates and when kernels are updated to compatible kernels (e.g. for security updates, or normally for any update within an Enterprise distribution), kernel modules are automatically applied against the updated kernel.


8.1.2.7 General REPO-MD Repository

To avoid having to change the openss7.repo file contents if they should change on the archive, place the following into the openss7.repo and place it into your /etc/yum.repo.d/ directory:

-| include=https://www.openss7.org/repo/rpms/centos/$releasever/$arch/repodata/openss7.repo

If you have difficulty downloading the openss7.repo file, edit the following information into the file and place it into the /etc/yum.repo.d/openss7.repo file:

-| [openss7]
-| name = OpenSS7 Repository
-| baseurl = https://www.openss7.org/repo/rpms/centos/$releasever/$arch
-| gpgkey = https://www.openss7.org/repo/tarballs/OPENSS7-GPG-KEY
-| repo_gpgcheck = 1
-| gpgcheck = 1
-| enabled = 1

Note that it is also possible to point to these repositories as an additional installation source when installing CentOS, RedHat, Fedora, or others. You will have an additional STREAMS category from which to choose installation packages.

The category that is provided is as follows:

openss7-components’ – OpenSS7 STREAMS and Protocol Suite Components.

The groups (patterns) that are provided in this category are as follows:

openss7’ — OpenSS7 STREAMS and Protocol Suites. This group

(pattern) installs packages required for the Linux Fast-STREAMS and OpenSS7 Protocol Suites run-time libraries, commands, utilities, init scripts and kernel modules. Also included are section 1, 4, 5 and 8 manual pages for the commands, module and drivers, configuration file formats and administrative utilities.

Install this group (pattern) if you need the Linux Fast-STREAMS and OpenSS7 Protocol Suties core run-time.

The mandatory (required) packages in this group (pattern) are ‘openss7’, ‘openss7-base’, ‘openss7-lib’ and ‘openss7-kernel’. The default (recommended) packages in this group (pattern) are ‘openss7-java’. The optional (suggested) packages in this group (pattern) are ‘openss7-devel’, ‘openss7-devel-kernel’, ‘openss7-doc’, ‘openss7-javadoc’ and ‘openss7-source-kernel’.

openss7-java’ — OpenSS7 STREAMS and Protocol Suite Java Components.

This group (pattern) installs packages required for the Linux Fast-STREAMS and OpenSS7 JAIN Java components.

The mandatory (required) packages in this group (pattern) are ‘openss7-java’. The optional (suggested) packages in this group (pattern) are ‘openss7-javadoc’.

openss7-devel’ — OpenSS7 STREAMS and Protocol Suite Development.

The mandatory (required) packages in this group (pattern) are ‘openss7-devel’ and ‘openss7-devel-kernel’. The optional (suggested) packages in this group (pattern) are ‘openss7-doc’, ‘openss7-javadoc’ and ‘openss7-source-kernel’.

openss7-doc’ — OpenSS7 STREAMS and Protocol Suite Documentation.

The mandatory (required) packages in this group (pattern) are ‘openss7-doc’ and ‘openss7-javadoc’.

For assistance with specific RPMs, see Downloading the Binary RPM.


8.1.3 Repositories for YAST

For distributions that support YaST, such as SUSE Linux Enterprise Server, and OpenSUSE, YaST repositories are built coexistent with repo-md repositories. Setting up the installation source as a YaST installation source instead of repo-md can provide the additional features associated with YaST install sources.


8.1.3.1 Setting up YAST

$> REPODIR="https://www.openss7.org/repo/rpms/suse/11/x86_64"
$> sudo zypper addrepo --type yast2 $REPODIR openss7

8.1.4 Repositories for URPMI

For distributions that support urmpi(8), such as Mageia, Mandriva and MES, urpmi(8) repositories are built. Setting up the installation source as a urpmi(8) installation source instead of repo-md can provide the additional features associated with urpmi(8) install sources.


8.1.4.1 Setting up URPMI

To install or upgrade from the OpenSS7 urpmi repositories using urpmi(8), you will need to install the openss7-repo RPM on your system as follows:

$> REPO="https://user@www.openss7.org/repo/repms"
$> REPONOARCH="$REPO/mageia/1/x86_64/RPMS/noarch"
$> REPORPM="$REPONOARCH/openss7-repo.noarch.rpm"
$> sudo rpm -Uhv $REPORPM
$> Username: anonymous
$> Password: *******

The example, above, assumes that the distribution is ‘mageia’ and the distribution release is ‘1’ and the required architecture is ‘x86_64’. Another example would be $REPO/mes/5.2/x86_64/RPMS/noarch, for using urpmi(8) with MES (Mandriva Enterprise Server).

To obtain access to the respository at the level to which you are entitled, you will have to respond to the ‘Username:’ query with the user name with which you are registered with http://www.openss7.org/, and to the ‘Password:’ query with your repository access password.33

You can test whether the urpmi(8) repository is properly set up by refreshing the repository with urpmi.update(8) and by listing the packages with urpmq(8):

$> sudo urpmi.update
$> sudo urpmq -a | grep openss7
$> sudo urpmq -ivl openss7

Note that only the packages to which you are entitled will be listed.


8.1.4.2 Using the URPMI Repository

Once the repository is set up, OpenSS7 include a number of virtual package and package group definitions that ease the installation and removal of kernel modules, libriaries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is as easy as (one of):

$> sudo urpmi openss7

Removing the package is as easy as (one of):

$> sudo urpme openss7

To install the development packages for developing STREAMS modules and drivers, or applications that use the OpenSS7 Protocol Suites, install the development packages using (one of):

$> sudo urpmi openss7-devel

Of course, you are welcome to use a GUI based package manager, such as rpmdrake(8).


8.1.4.3 URPMI Kernel Updates

The OpenSS7 urpmi(8) repository definitions support the automatic updating of kernel modules when kernels are updated. When the system is updated, using ‘urpmi’, openss7 packages that are available for an updated kernel will be installed automatically. OpenSS7 kernel module packages also support weak updates and when kernels are updated to compatible kernels (e.g. for security updates, or normally for any update within an Enterprise distribution), kernel modules are automatically applied against the updated kernel.


8.1.5 Repositories for APT

For assistance with specific DEBs, see Downloading the Debian DEB.


8.1.5.1 Setting up APT

To install or upgrade from the OpenSS7 apt repositories using apt(8), you will need to install the openss7-repo DEB on your system, as follows:

$> REPO="https://user@www.openss7.org/repo/debs"
$> REPONOARCH="$REPO/debian/squeeze/amd64"
$> REPODEB="$REPONOARCH/openss7-repo_all.deb"
$> wget $REPODEB
$> dpkg -i -D010077 openss7-repo_all.deb
$> Username: anonymous
$> Password: ********

The example, above, assumes that the distribution is ‘debian’ and the distribution release is ‘squeeze’ and the required architecture is ‘amd64’.34 Another example would be $REPO/ubuntu/10.04/amd64, for using apt(8) with Ubuntu.

To obtain access to the repository at the level to which you are entitled, you will have to respond to the ‘Username:’ query with the user name with which you are registered with https://www.openss7.org/, and to the ‘Password:’ query with your repository access password.35

apt(8) does not do a very good job of importing GPG signatures. When apt-get is reporting that there are no keys for the DEBs being installed, the key can be imported directly into APT as follows:

$> wget https://www.openss7.org/pubkey.asc
$> sudo apt-key add pubkey.asc

You can test whether the apt(8) repository is properly set up by refreshing the repository and by listing the packages.

$> sudo apt-get update
$> aptitude search openss7

8.1.5.2 Using the APT Repository

Once the repository is set up, OpenSS7 includes a number of virtual packages and packages recommendations that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is as easy as:36

$> sudo aptitude install openss7

Removing the package is as easy as:

$> sudo aptitude remove openss7
$> sudo aptitude purge openss7

To install the development packages for developing STREAMS modules and drivers, or applications that use the OpenSS7 Protocol Suites, install the development packages using:

$> sudo aptitude install openss7-devel

Of course, you are welcome to use a GUI based package manager, such as synaptic(8).


8.1.5.3 APT Kernel Updates

The OpenSS7 apt(8) repository definitions support the automatic updating of kernel modules when kernels are updated. When the system is updated, using ‘apt-get upgrade’, OpenSS7 packages that are available for an updated kernel will be installed automatically.

OpenSS7 kernel module packages also support weak updates and when kernels are updated to compatible kernels (e.g. for security upgrades, or normally for any updated within an Enterprise (LTS) distribution), kernel modules are automatically applied against the updated kernel.


8.1.5.4 Setting up APT-RPM

To install or upgrade from the OpenSS7 apt-rpm repositories using apt(8), you will need to install the openss7-repo RPM on your system, as follows:

$> REPO="https://user@www.openss7.org/repo/rpms"
$> REPONOARCH="$REPO/mageia/1/x86_64/RPMS/noarch"
$> REPORPM="$REPONOARCH/openss7-repo.noarch.rpm"
$> wget $REPORPM
$> sudo rpm -Uhv $REPORPM
$> Username: anonymous
$> Password: *******

The example, above, assumes that the distribution is ‘mageia’ and the distribution release is ‘1’ and the required architecture is ‘x86_64’. Another example would be $REPO/mes/5.2/x86_64/RPMS/noarch, for using apt(8) with MES (Mandriva Enterprise Server).

To obtain access to the repository at the level to which you are entitled, you will have to respond to the ‘Username:’ query with the user name with which you are registered with https://www.openss7.org/, and to the ‘Password:’ query with your repository access password.37

apt(8) does not do a very good job of importing GPG signatures. When apt-get is reporting that there are no keys for the DEBs being installed, the key can be imported directly into APT as follows:

$> wget https://www.openss7.org/pubkey.asc
$> sudo apt-key add pubkey.asc

You can test whether the apt(8) repository is properly set up by refreshing the repository and by listing the packages.

$> sudo apt-get update
$> sudo apt-cache gencaches
$> apt-cache search openss7

8.1.5.5 Using the APT-RPM Repository

Once the repository is set up, OpenSS7 includes a number of virtual packages and packages recommendations that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is as easy as:38

$> sudo apt-get install openss7

Removing the package is as easy as:

$> sudo apt-get remove openss7
$> sudo apt-get purge openss7

To install the development packages for developing STREAMS modules and drivers, or applications that use the OpenSS7 Protocol Suites, install the development packages using:

$> sudo apt-get install openss7-devel

Of course, you are welcome to use a GUI based package manager, such as synaptic(8).


8.1.5.6 APT-RPM Kernel Updates

The OpenSS7 apt(8) repository definitions support the automatic updating of kernel modules when kernels are updated. When the system is updated, using ‘apt-get upgrade’, OpenSS7 packages that are available for an updated kernel will be installed automatically.

OpenSS7 kernel module packages also support weak updates and when kernels are updated to compatible kernels (e.g. for security upgrades, or normally for any updated within an Enterprise (LTS) distribution), kernel modules are automatically applied against the updated kernel.

8.1.6.1 Setting up ALPM


8.1.6.2 Using the ALPM Repository


8.1.6.3 ALPM Kernel Updates


8.2 Downloading

The OpenSS7 package releases can be downloaded from the downloads page of The OpenSS7 Project. The package is available as a binary RPM (for popular architectures) a source RPM, Debian binary DEB and source DSC, or as a tar ball. If you are using a browsable viewer, you can obtain the OpenSS7 release of OpenSS7 from the links in the sections that follow.

By far the easiest (most repeatable and manageable) form for installing and using the OpenSS7 packages is to download and install the repository definition and use the distribution’s native packaging tools. Another (still repeatable and manageable) form for installing and using OpenSS7 packages is to download and install individual packages from binary RPM or DEB.

If binary RPMs or DEBs are not available for your distribution, but your distribution supports rpm(8) or dpkg(1), the next best method for installing and using OpenSS7 packages is to download and rebuild the source RPMs or DSCs.39

If your architecture does not support rpm(8) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets or for development), the final resort method is to download, configure, build and install from tarball. In this later case, the easiest way to build and install OpenSS7 packages is from tarball.40


8.2.1 Downloading with YUM

Once the repository definitions have been established, downloading RPMs with yum(8) is automatic. See Setting up YUM, for instructions on downloading the repository RPM and using it to set up for yum(8), and Installing with YUM, for instructions on installing subsequent packages. See yum(8) for more information on downloading without installing.


8.2.2 Downloading with ZYPPER

Once the repository definitions have been established, downloading RPMs with zypper(8) is automatic. See Setting up ZYPPER, for instructions on downloading the repository RPM and using it to set up for zypper(8), and Installing with ZYPPER, for instructions on installing subsequent packages. See zypper(8) for more information on downloading without installing.


8.2.3 Downloading with URPMI

Once the repository definitions have been established, downloading RPMs with urpmi(8) is automatic. See Setting up URPMI, for instructions on downloading the repository RPM and using it to set up for urpmi(8), and Installing with URPMI, for instructions on installing subsequent packages. See urpmi(8) for more information on downloading without installing.


8.2.4 Downloading with APT

Once the repository definitions have been established, downloading DEBs with apt(8) is automatic. See Setting up APT, for instructions on downloading the repository DEB and using it to set up for apt(8). See Setting up APT-RPM, for instructions on downloading the repository RPM and using it to set up for apt(8). See Installing with APT, for instructions on installing subsequent packages. See apt(8) for more information on downloading without installing.


8.2.5 Downloading the Binary RPM

To install from binary RPM, you will need several of the RPM for a complete installation. Binary RPM fall into several categories. To download and install a complete package requires the appropriate RPM from each of the several categories below, as applicable. Some release packages do not provide RPMs in each of the several categories.

To install from Binary RPM, you will need all of the following kernel independent packages for your architecture, and one of the kernel-dependent packages from the next section.

Independent RPM

Independent RPM are not dependent on the Linux kernel version. For example, the source package ‘openss7-source-1.1.7.20141001-1.noarch.rpm’, is not dependent on kernel.

All of the following kernel independent RPM are required for your architecture. Binary RPMs listed here are for example only: additional binary RPMs are available from the downloads site. If your architecture is not available, you can build binary RPM from the source RPM (see Building from the Source RPM).

Architecture Independent

Architecture independent RPMs are not dependent upon the processor architecture. That is, they are ‘noarch’ RPMs. The architecture independent RPMs in the OpenSS7 components are as follows:

openss7-repo-1.1.7.20141001-1.noarch.rpm

This packages can be used to install or remove the repository source definitions for all OpenSS7 release packages. On systems that support repository access, this package is required by the other packages.

openss7-1.1.7.20141001-1.noarch.rpm

This package can be used to install or remove the entire OpenSS7 package. When installing, kernel modules will be installed automatically for the highest version kernel on your system. When removing, all corresponding kernel modules will also be removed.

openss7-base-1.1.7.20141001-1.noarch.rpm

The openss7-base binary package contains the init scripts, test scripts, maintenance scripts and base system configuration files necessary for the operation of Linux Fast-STREAMS and the protocol suites contained in the OpenSS7 package. It contains user and administrative documentation in .info, .pdf and .html formats as well as sections 1, 4, 5 and 8 of the manual pages. This binary package is required for any installation of the OpenSS7 package and is not architecture specific (‘noarch’).

openss7-doc-1.1.7.20141001-1.noarch.rpm

The openss7-doc binary package contains the documentation used in the development of applications and programs that use the package. It contains developer and programmer manuals in .info, .pdf and .html formats as well as sections 2, 3, 7 and 9 of the manual pages and Javadoc HTML documentation. Install this binary package if you are interested in developing Linux Fast-STREAMS drivers or modules or application programs for the protocol suites contained in the OpenSS7 package. This package is massive and is not normally necessary except on a development system. The package is not architecture specific (‘noarch’).

openss7-javadoc-1.1.7.20141001-1.noarch.rpm

The openss7-javadoc binary package contains Javadoc documentation for the OpenSS7 package. Install this binary package if you are interested in developing JAIN applications or resource adaptors. This package is not normally required on other than a development system. The package is not architecture specific (‘noarch’).

Architecture Dependent

Architecture dependent RPMs are dependent upon the processor architecture (but not on the specific kernel version). That is, they are ‘i686’ RPMs. The architecture dependent RPMs in the OpenSS7 components are as follows:

openss7-lib-1.1.7.20141001-1.i686.rpm

The openss7-lib binary package contains the run-time (shared object) libraries necessary to run applications programs and utilities developed for Linux Fast-STREAMS and the protocol suites contained in the OpenSS7 package. Also included are the libtool .la files describing the shared object libraries. The binary package also provides administrative and configuration test utilities and commands associated with the OpenSS7 package. Note that these utilities are needed for running the validation test suites contained in the openss7-base binary package.

openss7-java-1.1.7.20141001-1.i686.rpm

The openss7-java binary package contains JAIN implementations for OpenSS7 Linux Fast-STREAMS and the associated protocol suites. It includes jar files, JNI and CNI libraries, and gcj native compiled libraries. It also includes SWIG implementations of Java interfaces for OpenSS7 API libraries.

openss7-devel-1.1.7.20141001-1.i686.rpm

The openss
