OpenSS7 INET Networking Installation and Reference Manual

About This Manual

This is Edition 7, last updated 2008-10-31, of The OpenSS7 INET Networking Installation and Reference Manual, for Version 0.9.2 release 7 of the OpenSS7 INET Networking package.

Preface

Notice

This package is released and distributed under the AGPL (see GNU Affero General Public License). 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 sections invariant.

Abstract

This manual provides a Installation and Reference Manual for OpenSS7 INET Networking.

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 INET Networking.

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 INET Networking 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 INET Networking 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.

Quick Start Guide

OpenSS7 INET Networking

Package strinet-0.9.2.7 was released under AGPLv3 2008-10-31.

The OpenSS7 INET Networking package is an implementation of the Internet Protocol suite for Linux Fast-STREAMS directly over Linux NET4 Sockets implementation, using a STREAMS over Sockets approach. This permits modules to be pushed on UDP or TCP Streams and allows use of the XTI/TLI library with Internet Protocols on Linux. The package now also includes direct STREAMS implementations of RAW IP and UDP, and will include direct implementations of TI loop back devices and TCP in the future.

The package currently includes the following STREAMS kernel modules and drivers:

streams_inet.ko /dev/ip others
streams_udp.ko /dev/udp2
streams_rawip.ko /dev/rawip2
streams_tcp.ko /dev/tcp2
inet(4)
The inet(4) driver is a classical STREAMS over Sockets approach. Transport Provider Interface, tpi(7), Streams are inter-worked into a socket opened within the driver. This approach has some serious disadvantages, one of them being speed.
udp2(4)
The udp2(4) driver is a second-generation STREAMS UPD driver. This driver is mostly a STREAMS implementation and only relies on the Linux IP layer for operation. No socket is opened internal to the kernel. This driver performs much faster than the STREAMS over Sockets approach and rivals the native Sockets implemented under Linux in terms of performance. This driver is well tested with the test-udp test case executable.
rawip2(4)
The rawip2(4) driver is a second-generation STREAMS raw IP driver. It is similar to the second-generation UDP driver. This driver is well tested with the test-rawip test case executable.
tcp2(4)
The tcp2(4) driver is a placeholder for a second-generation STREAMS TCP driver.

The OpenSS7 INET Networking package includes kernel modules, SVR 4.2 STREAMS drivers, modules, libraries, utilities, test programs, daemons, and development environment for the development and execution of Internet Protocols (INET) protocol stack components and applications for the Linux Fast-STREAMS environment.

This distribution is only currently applicable to Linux 2.4 and 2.6 kernels and was targeted at ix86, x86_64, ppc and ppc64 architectures, but should build and install for other architectures as well.

Release

This is the strinet-0.9.2.7 package, released 2008-10-31. This ‘0.9.2.7’ release, and the latest version, can be obtained from the download area of The OpenSS7 Project website using a command such as:

     $> wget http://www.openss7.org/tarballs/strinet-0.9.2.7.tar.bz2

The release is available as an autoconf(1) tarball, src.rpm or dsc, as a set of binary rpms or debs, or as a yum(8) or apt(8) repository. See the download page for the autoconf(1) tarballs, src.rpms, dscs, or repository access instructions. See the strinet package page for tarballs, source and binary packages.

Please see the NEWS file for release notes and history of user visible changes for the current version, and the ChangeLog file for a more detailed history of implementation changes. The TODO file lists features not yet implemented and other outstanding items.

Please see the INSTALL, INSTALL-strinet and README-make, files (or see Installation) for installation instructions.

When working from cvs(1) or git(1), please see the README-cvs, file (or see Downloading from CVS). An abbreviated installation procedure that works for most applications appears below.

This release of the package is published strictly under Version 3 of the GNU Affero Public License which can be found in the file COPYING. Package specific licensing terms (if any) can be found in the file LICENSES. Please respect these licensing arrangements. If you are interested in different licensing terms, please contact the copyright holder, or OpenSS7 Corporation <sales@openss7.com>.

See README-alpha (if it exists) for alpha release information.

Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.G, instead of separately.

Prerequisites for the OpenSS7 INET Networking package are as follows:

  1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 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.3
    − Linux 2.4 kernel (2.4.10 - 2.4.27), or
    − Linux 2.6 kernel (2.6.3 - 2.6.26);
    − glibc2 or better.
    − GNU groff (for man pages).4
    − GNU texinfo (for info files).

(Note: If you acquired strinet a part of the OpenSS7 Master Package, then the dependencies listed below will already have been met by unpacking the master package.)

  1. OpenSS7 Linux Fast-STREAMS, streams-0.9.2.4. 5
  2. OpenSS7 STREAMS Compatibility Modules, strcompat-0.9.2.7.
  3. OpenSS7 STREAMS XNS, strxns-0.9.2.7.
  4. OpenSS7 STREAMS XTI/TLI, strxnet-0.9.2.12.

When configuring and building multiple OpenSS7 Project release packages, place all of the source packages (unpacked tarballs) at the same directory level and all build directories at the same directory level (e.g. all source packages under /usr/src).

When installing packages that install as kernel modules, it is necessary to have the correct 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

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:

     $> ../strinet-0.9.2.7/configure CC='gcc-3.4'

Installation

The following commands will download, configure, build, check, install, validate, uninstall and remove the package:

     $> wget http://www.openss7.org/tarballs/strinet-0.9.2.7.tar.bz2
     $> tar -xjvf strinet-0.9.2.7.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../strinet-0.9.2.7/configure --enable-autotest
     $> make
     $> make check
     $> sudo make install
     $> sudo make installcheck
     $> sudo make uninstall
     $> popd
     $> sudo rm -rf build
     $> rm -rf strinet-0.9.2.7
     $> rm -f strinet-0.9.2.7.tar.bz2

If you have problems, try building with the logging targets instead. If the make of a logging target fails, an automatic problem report will be generated that can be mailed to The OpenSS7 Project.6 Installation steps using the logging targets proceed as follows:

     $> wget http://www.openss7.org/tarballs/strinet-0.9.2.7.tar.bz2
     $> tar -xjvf strinet-0.9.2.7.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../strinet-0.9.2.7/configure --enable-autotest
     $> make compile.log
     $> make check.log
     $> sudo make install.log
     $> sudo make installcheck.log
     $> sudo make uninstall.log
     $> popd
     $> sudo rm -rf build
     $> rm -rf strinet-0.9.2.7
     $> rm -f strinet-0.9.2.7.tar.bz2

See README-make for additional specialized make targets.

For custom applications, see the INSTALL and INSTALL-strinet files or the see Installation, as listed below. If you encounter troubles, see Troubleshooting, before issuing a bug report.

Brief Installation Instructions

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

     $> wget http://www.openss7.org/tarballs/strinet-0.9.2.7.tar.bz2

Unpack the tarball using a command such as:

     $> tar -xjvf strinet-0.9.2.7.tar.bz2

The tarball will unpack into the relative subdirectory named after the package name: strinet-0.9.2.7.

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
     $> ../strinet-0.9.2.7/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 ../strinet-0.9.2.7/INSTALL

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

     $> ../strinet-0.9.2.7/configure --help

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

     $> make

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 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 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 strinet-0.9.2.7
     $> rm -f strinet-0.9.2.7.tar.bz2

Detailed Installation Instructions

More detailed installation instructions can be found in the Installation, contained in the distribution in ‘text’, ‘info’, ‘html’ and ‘pdf’ formats:

     $> cd ../strinet-0.9.2.7
     $> less doc/manual/strinet.txt
     $> lynx doc/manual/strinet.html
     $> info doc/manual/strinet.info
     $> xpdf doc/manual/strinet.pdf

The ‘text’ version of the manual is always available in the MANUAL file in the release.

The current manual is also always available online from The OpenSS7 Project website at:

2 Objective

The OpenSS7 INET Networking package is intended to provide compatibility with UNIX System V Release 4 networking components based on the Transport Provider Interface and the XTI/TLI interface described in X/Open Networking Services, in a single add-on package to Linux Fast-STREAMS. One purpose in achieving this compatibility is the porting of legacy applications from UNIX to Linux using the capabilities of STREAMS and Linux Fast-STREAMS.

Another objective of providing Transport Provider Interface Streams for Linux Fast-STREAMS was to permit sctp(4), tcp(4), udp(4) and rawip(4) Streams to be opened, linked under multiplexing drivers, and to have STREAMS modules pushed over them. The purpose was to provide access to the Internet Protocol suite to STREAMS modules and drivers written for the strss7-0.9a.8 sigtran-0.9.2.4 and strvoip-0.9.2.4 packages under the OpenSS7 Project, as well as to provide ISO over TCP capabilities for the striso-0.9.2.4 package.

The initial approach to implementing INET drivers was to provide an in-kernel STREAMS over Socket approach. Under this approach, the STREAMS inet(4) driver converts between TPI primitives received from the Stream head and in-kernel calls to an internally opened socket of the appropriate type. While this provided an adequate mechanism for providing Internet Protocol STREAMS presenting the TPI service interface, it is rather inefficient.

The second approach that is available in this release is a complete STREAMS implementation of the udp(4) and rawip(4) drivers, as well as the start of a skeleton for a fully STREAMS-based tcp(4) driver. Performance tests using the netperf-2.3.7 package shows that these second generation implementations of udp(4) and rawip(4) compete for performance with Linux native sockets. The ability to link these Streams underneath multiplexing drivers or pushed beneath modules for protocols such as rtp(4) is very beneficial.

The result is stable, production grade, 64-bit clean TPI implementations of Internet Protocols for Linux Fast-STREAMS that can be used by other STREAMS modules and drivers.

4 Development

OpenSS7 INET Networking provides all of the header files, shared object and static libraries, manual pages and documentation necessary for the development of both user space applications programs and kernel space STREAMS modules and drivers based on the package. The sections that follow describe these development facilities.

4.1 Header Files

Header files are installed, typically, in the /usr/include/strinet/ subdirectory. To use the header files from the package, ‘-I/usr/include/strinet’ must be included in the gcc command line as a preprocessor option.

In general, ‘-I’ include preprocessor 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/strinet’ ‘-I/usr/include/strxns’ ‘-I/usr/include/strcompat’ ‘-I/usr/include/streams’.

Following are the user visible header files provided by the strinet-0.9.2.7 package in the directory /usr/include/strinet:

sys/strinet/config.h
Configuration defines for the package.
sys/strinet/version.h
Module versions for the package (on 2.4 systems).
ticlts.h
sys/ticlts.h
Header file providing Transport Provider Interface definitions for the connectionless transport interface.
ticots.h
sys/ticots.h
Header file providing Transport Provider Interface definitions for the connection-oriented transport interface.
ticotsord.h
sys/ticotsord.h
Header file providing Transport Provider Interface definitions for the connection-oriented with orderly release transport interface.
xti.h
xti_inet.h
sys/xti_inet.h
Primary header files defining the XTI library interface. This header file is normally included by applications programs wishing to use the XTI library interface. See xti(3) for more information.
sys/xti_ip.h
System specific header file for the Internet Protocol XTI library interface. This header file is normally included by xti.h and does not need to be directly included by the applications program. See xti(3) for more information.
sys/xti_udp.h
System specific header file for the User Datagram Protocol XTI library interface. This header file is normally included by xti.h and does not need to be directly included by the applications program. See xti(3) for more information.
sys/xti_tcp.h
System specific header file for the Transmission Control Protocol XTI library interface. This header file is normally included by xti.h and does not need to be directly included by the applications program. See xti(3) for more information.

4.1.1 User Space Programs

Typical include files for interacting with Transport providers from user space include the xti.h header file. Additional header files for interacting with specific drivers or modules may also be required. The xti.h header file is for interacting with the XTI library.

4.1.2 Kernel Space Drivers and Modules

Typical include files for writing STREAMS module and drivers implementing transport providers in kernels space include xti.h and xti_inet.h. The header files provide access to definitions for the TPI interface and additional XTI definitions for use by STREAMS drivers and modules. Additional header files for interacting with specific drivers or modules may also be required.

Aside from including this header files, the general procedures for compiling STREAMS modules and drivers also apply to STREAMS modules and drivers written to the Transport Provider Interface.

4.2 Libraries

Shared or static version of the libxnet library may be linked when using the strinet-0.9.2.7 package.12 The library may either be specified on the gcc command line as a shared library (e.g. ‘-lxnet’) or as a static library (e.g. ‘/usr/lib/libxnet.a’).

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

-lxnet
Link to the /usr/lib/libxnet.so shared library.

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

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

4.3 Kernel Modules

Developing TPI kernel modules is similar to user space programs with regard to header files. /usr/include/strxnet should be placed as an include directory to search on the gcc command line. The rules for compiling Linux kernel modules and the rules for compiling STREAMS modules and drivers 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 and STREAMS base package.
  • The gcc command line must have the same compile flags that were used to compile the kernel and STREAMS base package. kbuild can be used to accomplish this.
  • The gcc command line must define several important kernel defines including ‘-DLINUX’, ‘-D__KERNEL__’, as well as the base name of the module. Again, kbuild can be used to accomplish this.
  • The gcc command line must include several important files directly on the command line, such as, ‘--include /lib/modules/2.4.20-28.7/build/include/linux/autoconf.h’ and ‘--include /lib/modules/2.4.20-28.7/build/include/linux/modversions.h’.13

5 Conformance

The OpenSS7 INET Networking package is compliant to a number of standards specifications as follows:

5.1 TPI Compatibility

The Transport Provider Interface provided by the OpenSS7 INET Networking package is compliant with XPG3, XPG4, and the Transport Provider Interface (TPI) Revision 1.5 (from UNIX International) and Transport Provider Interface (TPI) Revision 2.0.0. (from The Open Group).

Conformance of the inet(4), udp(4), tcp(4) and rawip(4) drivers to the TPI specification is tested for compliance with the test-inet_raw(8), test-inet_tcp(8) and test-inet_udp(8) test case executables and the autotest test suite. See Conformance Test Programs, for more information.

5.2 XTI Compatibility

The X/Open Transport Interface provided by the OpenSS7 INET Networking package is compliant with XPG3, XPG4, and the X/Open Transport Interface present in X/Open Networking Services Release 4.2 (XNS 4.2) and X/Open Networking Services Release 5.2 (XNS 5.2), part of the standards necessary for UNIX '95 branding.

Conformance of the package to the XTI specification is not tested. Only the XTI/TLI Library from the strxnet-0.9.2.12 package is tested to the XTI specification. Provided that the INET drivers meet the TPI specification, they should automatically meet the XTI specification.

5.3 TLI Compatibility

The X/Open Transport Interface is not compatible with the older AT&T UNIX System Laboratories Transport Layer Interface (TLI) in a number of respects where the TLI differs from the XTI. Nevertheless, the older TLI declarations are also provided in the tiuser.h header file.

6 Releases

This is the OpenSS7 Release of the OpenSS7 INET Networking tools, drivers and modules used with the Linux Fast-STREAMS or Linux STREAMS14 SVR 4.2 STREAMS releases.

The purpose of providing a separate release of this package was to separate the OpenSS7 INET Networking tools, headers, drivers and modules from the Linux STREAMS15 package for use with both Linux STREAMS16 and Linux Fast-STREAMS in preparation for replacement of the former by the later.

The following sections provide information on OpenSS7 INET Networking releases as well as compatibility information of OpenSS7 release to mainstream UNIX releases of the core, modules and drivers, as well as Linux kernel compatibility.

6.1 Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.G, instead of separately.

Prerequisites for the OpenSS7 INET Networking package are as follows:

  1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 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.17
    − Linux 2.4 kernel (2.4.10 - 2.4.27), or
    − Linux 2.6 kernel (2.6.3 - 2.6.26);
    − glibc2 or better.
    − GNU groff (for man pages).18
    − GNU texinfo (for info files).

(Note: If you acquired strinet a part of the OpenSS7 Master Package, then the dependencies listed below will already have been met by unpacking the master package.)

  1. OpenSS7 Linux Fast-STREAMS, streams-0.9.2.4. 19
  2. OpenSS7 STREAMS Compatibility Modules, strcompat-0.9.2.7.
  3. OpenSS7 STREAMS XNS, strxns-0.9.2.7.
  4. OpenSS7 STREAMS XTI/TLI, strxnet-0.9.2.12.

If you need to rebuild the package from sources with modifications, you will need a larger GNU tool chain as described in See Downloading from CVS.

6.2.2 Kernel

The OpenSS7 INET Networking package compiles as a Linux kernel module. It is not necessary to patch the Linux kernel to build or use the package.21 Nor do you have to recompile your kernel to build or use the package. OpenSS7 packages use autoconf 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 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.

The OpenSS7 INET Networking package is compatible with 2.4 kernel series after 2.4.10 and has been tested up to and including 2.4.27. It has been tested from 2.6.3 up to and including 2.6.26 (with Fedora 9, openSUSE 11.0 and Ubuntu 8.04 patchsets). Please note that your mileage may vary if you use a kernel more recent than 2.6.26.4: it is difficult to anticipate changes that kernel developers will make in the future. Many kernels in the 2.6 series now vary widely by release version and if you encounter problems, try a kernel within the supported series.

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) as well as dual quad-core SunFire (8x) servers.

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.

6.2.3 Architectures

The OpenSS7 INET Networking 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

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.

6.2.4 Linux STREAMS

The OpenSS7 INET Networking package is currently compatible with Linux STREAMS,22 however, to use the OpenSS7 INET Networking package with LiS requires use of the OpenSS7 release packages of LiS. The OpenSS7 INET Networking package is compatible with the OpenSS7 LiS-2.18.7 release that is available from the The OpenSS7 Project Downloads Page. But, do not use LiS: it is buggy, unsupported and deprecated. Use Linux Fast-STREAMS instead.

6.2.5 Linux Fast-STREAMS

The OpenSS7 INET Networking package is currently compatible with Linux Fast-STREAMS (LfS). The OpenSS7 INET Networking package is compatible with the OpenSS7 streams-0.9.2.4 release that is available from the The OpenSS7 Project Downloads Page.

6.3 Release Notes

The sections that follow provide information on OpenSS7 releases of the OpenSS7 INET Networking package.

Major changes for release strinet-0.9.2.7

This is the seventh separate OpenSS7 Project release of the OpenSS7 INET Networking package that was formerly present in the (long deprecated) LiS package. The networking drivers are provided, as well as the TPI and XTI header files for INET and loop back operation. The package contains all the necessary manual pages and other documentation for INET components in a separate autoconf tarball.

This release is a stable, production grade release for Linux Fast-STREAMS and is part of the OpenSS7 Master Package (openss7-0.9.2.G). The release includes maintenance support for recent distributions and tool chain, but also includes some performance and feature upgrades and inspection bug fixes. It deprecates previous releases. Please upgrade before reporting bugs on previous releases.

This release is primarily a maintenance release.

Major features since the last public release are as follows:

  • Minor documentation corrections.
  • Kernel module license made explicit "GPL v2". And then changed back to "GPL".
  • License upgrade to AGPL Version 3.
  • Modifications to build under Fedora2.6.22.5-49’ kernel. These changes also support ‘2.6.22.9-91.fc7’ kernel. Handle tcp_push_pending_frames with fewer arguments and new sk_buff format (offsets and transport_header).
  • Ability to strap out major documentation build and installation primarily for embedded targets.
  • Improvements to common build process for embedded and cross-compile targets.
  • Modifications to build under Fedora2.6.25-45.fc9’ and ‘2.6.26.5-45.fc9’ kernels.
  • Updated tool chain to m4-1.4.12, autoconf-2.63 and texinfo-4.13.
  • Conversion of RPM spec files to common approach for major subpackages.
  • Updated references database for manual pages and roff documents.
  • Build system now builds yum(8) repositories for RPMs and apt-get(8) repositories for DEBs. Installation documentation has been updated to include details of repository install sourcesref.
  • Added MODULE_VERSION to all modules and drivers.
  • This release contains a significant rework of the inet driver. The driver is now instrumented using the mi_strlog(9) function and uses Mentat Portable STREAMS compatability functions extensively. The driver has been validated over a wider range of kernels and distributions on SMP machines. This drive will no longer work with the long deprecated LiS and, with this release, is exclusively for use with Linux Fast-STREAMS. Please see BUGS in the release to see which bugs this rework addressed.

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 strinet package page.

See http://www.openss7.org/codefiles/strinet-0.9.2.7/ChangeLog and http://www.openss7.org/codefiles/strinet-0.9.2.7/NEWS in the release for more information. Also, see the strinet.pdf manual in the release (also in html http://www.openss7.org/strinet_manual.html).

Major changes for release strinet-0.9.2.6

This OpenSS7 Project release is another separate add-on package release of the OpenSS7 INET Networking package that was formerly present in the (long deprecated) LiS package. The networking drivers are provided, as well as the TPI and XTI header files for INET and loop back operation. The package contains all the necessary manual packages and other documentation for INET components in a separate autoconf tarball. This release is a stable, production grade release for Linux Fast-STREAMS and is part of the OpenSS7 Master Package (openss7-0.9.2.F).

This release is primarily a maintenance release to support 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 with 2.6.21 kernel.
  • Support build on CentOS 5.0 (RHEL5).
  • Support build on Ubuntu 7.04.
  • Updated to gettext 0.16.1.
  • Changes to support build on 2.6.20-1.2307.fc5 and 2.6.20-1.2933.fc6 kernel.
  • Supports build on Fedora Core 6.
  • Support for recent distributions and tool chains.

Major changes for release strinet-0.9.2.5

This OpenSS7 Project release is another separate add-on package release of the OpenSS7 INET Networking package that was formerly present in the (long deprecated) LiS package. The networking drivers are provided, as well as the TPI and XTI header files for INET and loop back operation. The package contains all the necessary manual packages and other documentation for INET components in a separate autoconf tarball. This release is a stable, production grade release for Linux Fast-STREAMS and is part of the OpenSS7 Master Package (openss7-0.9.2.E).

This release is primarily a maintenance release to support recent distributions and tool chains.

Major features since the last public release are as follows:

  • Improvements to the common build environment with better support for standalone package builds on 2.4 kernels.
  • Support for autoconf 2.61, automake 1.10 and gettext 0.16.
  • Support for Ubuntu 6.10 distribution and bug fixes for i386 kenels.
  • The package now looks for other subpackages with a version number as unpacked by separate tarball.

Major changes for release strinet-0.9.2.4

This OpenSS7 Project release is another separate add-on package release of the OpenSS7 INET Networking package that was formerly present in the (now deprecated) LiS package. The networking drivers are provided, as well as the TPI and XTI header files for INET and loop back operation. The package contains all the necessary manual packages and other documentation for INET components in a separate autoconf tarball. This release is a stable, production grade release for Linux Fast-STREAMS and is part of the OpenSS7 Master Package (openss7-0.9.2.D).

This release is both a maintenance release and a feature release. The major new feature added is a fully STREAMS based implementation of the rawip(4) and udp(4) drivers. This release is a stable production release for Linux Fast-STREAMS. Support for LiS is deprecated as of this release.

The release provides the following enhancements and fixes:

  • Support for most recent 2.6.18 kernels (including Fedora Core 5 with inode diet patch set).
  • Fixed buffer leak in ‘ss_sock_sendmsg’ reported by John Wenker. Significant rewrite of the ss_sock_sendmsg function. Loader optimizations for streams-inet driver.
  • 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.
  • Many documentation updates for all OpenSS7 packages. Automated release file generation making for vastly improved and timely text documentation present in the release directory.
  • Dropped support for LiS.
  • Updated init scripts for proper addition and removal of modules.
  • 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. strinet 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.
  • Improved compiler flag generation and optimizations for recent gcc compilers and some idiosyncratic behaviour 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-devel configure 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.

Major changes for release strinet-0.9.2.3

This release is primarily to support additional compilers (gcc 4.0.2), architectures (x86_64, SMP, 32-bit compatibility), recent Linux distributions (EL4, SuSE 10, LE2006, OpenSuSE) and kernels (2.6.15).

This is primarily a maintenance release. Validated for operation on x86_64 SMP kernel using Linux Fast-STREAMS. Changes included to handle __LP64__ kernels. Corrected build flags for Gentoo and 2.6.15 kernels as reported on mailing list. Corrects several bugs reported by project sponsors.

  • Changes necessary for __LP64__ compatible builds. Changes to support 32-bit ioctl compatibility for __LP64__ architectures. Binary compatibility should not have been disrupted. At the same time as the ioctl32 changes, TRANSPARENT ioctl support for most of the IO controls for the ldl(4) driver has been added.
  • Changes to satisfy gcc 4.0.2 compiler.
  • Corrections for and testing of 64-bit clean compile and test runs on x86_64 architecture. Some bug corrections resulting from gcc 4.0.2 compiler warnings.
  • Corrected build flags for Gentoo and 2.6.15 kernels as reported on mailing list.
  • Initial corrections for and testing of SMP operation on Intel 630 Hyper-Threaded SMP on x86_64. This package should now run well on N-way Xeons even with Hyper-Threading enabled.
  • Corrections and validation of 32-bit compatibility over 64-bit on x86_64. Should apply well to other 64-bit architectures as well.

This is a public gamma release of the package.

Major changes for release strinet-0.9.2.2

This is primarily a bug fixes release. This release has been verified (conformance test suite passes) for operation with Linux Fast-STREAMS (streams-0.7a.4). Some test cases were updated because LiS was not operating correctly on pipes (does not send SIGPIPE on write error contrary to POSIX).

Major changes for release strinet-0.9.2.1

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. The package also supports both LiS-2.18.1 as well as streams-0.7a on both kernels.

Initial release strinet-0.9.2-1

Initial autoconf/RPM packaging of the strinet release.

This was an internal alpha test release and was not released publicly.

6.4 Maturity

The OpenSS7 Project adheres to the following release philosophy:

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

6.4.1 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.

6.4.2 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.

6.4.3 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.

6.4.4 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.

6.4.5 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.

6.4.6 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.

6.5 Bugs

6.5.1 Defect Notices

OpenSS7 INET Networking could possibly contain unknown defects. This is a production release. Nevertheless, some remaining unknown defects could possibly be harmful. Validation testing has been performed by the OpenSS7 Project and external entities on this software for the set of systems listed in the release notes. Nevertheless, the software might still fail to configure or compile on other systems. The OpenSS7 Project recommends that you validate this software for your target system before using this software. Use at your own risk. Remember that there is NO WARRANTY.23

This software is production software. As such, it is stable on validated systems but might still crash your kernel in unique circumstances. Installation of the software on a non-validated distribution might mangle your header files or Linux distribution in such a way as to make it unusable. Crashes could possibly 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 stands a chance of crashing 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.

6.5.2 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 INET Networking had no known bugs at the time of release.

6.5.3 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
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

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

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.

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!

6.6 Schedule

Current Plan

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

This package will not be maintained for use with LiS. LiS support is deprecated and has been discontinuted (but still exists on the CVS archive for sponsors of the OpenSS7 Project). Use Linux Fast-STREAMS instead, please.

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*

  • Pure STREAMS RAW and UDP implementation. A higher performance RAW and UDP implementation supporting both TPI and NPI would be nice to have. The OpenSS7 Project needs an NPI RAW implementation that can tap UDP primarily for use with RTP. Also, it will be interesting to test the performance differences between STREAMS UDP and Sockets UDP.
    *done*
    udp2 and rawip2 drivers implemented and tested. strxns package now has an np_ip driver for raw access to IP (primarily for SCTP conformance testing). RTP drivers should be based on udp2 driver.
  • 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*

  • 32bit compatibility testing.
    *done*
    Ran ix86 test suite binaries on x86_64.

    (Note that 32bit over 64bit compatibility builds and conformance and validation testing is now a constituent part of all packages. 32-bit libraries and test programs are built automatically and multiple test runs of the test suite performed: once for native and once for compatibility.)

  • SMP Testing.
    *done*
    What I did was to perform SMP testing for Intel Pentium IV 630 HT at least.

    (Note that SMP testing on Pentium IV 630 HT is not a constituent part of the release cycle.)

6.7 History

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

7 Installation

7.1 Repositories

The OpenSS7 INET Networking package release can be accessed from the repositories of The OpenSS7 Project. For rpm(1) based systems, the package is available in a yum(8) repository based on repomd XML and may also be accessed using zypper(8) or yast(8). For dpkg(1) based systems, the package is available in a apt(8) repository.

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

If binaries are not available for your distribution or specific kernel, but your distribution supports rpm(1) 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(1) or dpkg(1).

If your architecture does not support rpm(1) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets), 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 from tarball is to use the tarball for the OpenSS7 Master Package, openss7-0.9.2.G.

7.1.1 Repositories for YUM

To install or upgrade from the OpenSS7 repomd repositories, you will need a file in your /etc/yum.repo.d/ directory. This file can be obtained directly from the OpenSS7 repository, like so:

     $> REPOS="http://www.openss7.org/repos/rpms"
     $> wget $REPOS/centos/5.2/x86_64/repodata/openss7.repo
     $> sudo cp -f openss7.repo /etc/yum.repo.d/
     $> sudo yum makecache

This example assumes the the distribution is ‘centos’ and the distribution release is ‘5.2’ and the architecture requires is ‘x86_64’. Another example would be $REPOS/i686/suse/11.0/i686/repodata/openss7.repo, for using yum(8) with SUSE.

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

     $> sudo yum install strinet

Removing the package is as easy as:

     $> sudo yum remove strinet

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]
     -| enabled = 1
     -| name = OpenSS7 Repository
     -| baseurl = http://www.openss7.org/repos/rpms/centos/5.2/x86_64
     -| gpgcheck = 1
     -| gpgkey = http://www.openss7.org/pubkey.asc

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.

Some additional installation real or virtual package names and the installations they accomplish are as follows:

strinet
This package can be used to install or remove the entire OpenSS7 INET Networking 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.
strinet-devel
This package can be used to install or remove the development components of the OpenSS7 INET Networking package. When installing, ‘strinet’ and appropriate kernel module and kernel module development and debug packages will also be installed. When removing, the development package and all kernel module development and debug packages will also be removed.
strinet-2.4.20-28.7
This package can be used to install or remove the package for a specific kernel version. When installing, the ‘strinet’ package will also be installed if necessary. When removing the last kernel module package, the ‘strinet’ package will also be removed.

Note that the version ‘2.4.20-28.7’ is just an example. Use the version returned by ‘$(uname -r)’ for the kernel for which you wish to install or remove the packages.

strinet-2.4.20-28.7-devel
This package can be used to install or remove the development and debug packages for a specific kernel version. When installing, the ‘strinet’ and ‘strinet-devel’ packages will also be installed if necessary. When removing the development and debug for kernel modules for the last kernel, the ‘strinet-devel’ package will also be removed.

Note that the version ‘2.4.20-28.7’ is just an example. Use the version returned by ‘$(uname -r)’ for the kernel for which you wish to install or remove the packages.

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

7.1.2 Repositories for APT

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

7.2 Downloading

The OpenSS7 INET Networking 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 strinet from the links in the sections that follow.

By far the easiest (most 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(1) or dpkg(1), the next best method for installing and using OpenSS7 packages is to download and rebuild the source RPMs or DSCs.

If your architecture does not support rpm(1) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets), 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 from tarball is to use the tarball for the OpenSS7 Master Package, openss7-0.9.2.G.

7.2.1 Downloading with YUM

OpenSS7 repositories support yum(8) and zypper(8) in repomd XML format as well as YaST and YaST2 formats.

OpenSS7 includes virtual packages that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuration, building and installation for a signle-kernel distribution installation is as easy as:

     % sudo yum install strinet

This and additional packages for installation are detailed as follows:

strinet
Install this package if you need the runtime strinet package.
          % sudo yum install strinet

This will install the strinet, strinet-lib and strinet-KVERSION RPMs, where ‘KVERSION’ is the highest version number kernel on your system.

Remove this package if you need to remove all vestages of the strinet package.

          % sudo yum remove strinet

This will remove the strinet, strinet-lib, strinet-devel, strinet-KVERSION and strinet-devel-KVERSION RPMs for all kernels on your system.

strinet-devel
Install this package if you need the development strinet package.
          % sudo yum install strinet-devel

This will install the strinet, strinet-lib, strinet-devel, strinet-KVERSION and strinet-devel-KVERSION RPMs, where ‘KVERSION’ is the highest version number kernel on your system.

Remove this package if you do not need development capabilities for the strinet package for any kernel.

          % sudo yum remove strinet-devel

This will remove the strinet-devel and strinet-devel-KVERSION RPMs for all kernels on your system.

strinet-2.4.20-28.7
Install this package if you need the runtime strinet for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can install the runtime strinet components with:
          % sudo yum install strinet-$(uname -r)

This will install the strinet, strinet-lib and strinet-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified.

Remove this package if you no longer need the runtime strinet for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can remove the runtime strinet components with:

          % sudo yum remove strinet-$(uname -r)

This will remove the strinet-2.4.20-28.7 and strinet-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified. Also, if this is the last kernel for which strinet was installed, the strinet strinet-lib and strinet-devel RPMs will also be removed.

Note that this is a virtual package name: the actual RPMs installed or removed from the system is a kernel module package whose precise name will depend upon the system being used.

strinet-devel-2.4.20-28.7
Install this package if you need the development strinet package for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can install the kernel development strinet components with:
          % sudo yum install strinet-devel-$(uname -r)

This will install the strinet, strinet-lib, strinet-devel, strinet-2.4.20-28.7 and strinet-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified.

Remove this package if you no longer need the development capabilities for the strinet package for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can remove the kernel development strinet components with:

          % sudo yum remove strinet-devel-$(uname -r)

This will remove the strinet-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified. Also, if this is the last kernel for which strinet was installed, the strinet-devel RPMs will also be removed.

Note that this is a virtual package name: the actual RPMs installed or removed from the system is a kernel module package whose precise name will depend upon the system being used.

strinet-lib
This package is an auxillary package that should be removed and inserted automatically by yum(8). In rare instances you might need to remove or install this package explicitly.

7.2.2 Downloading with APT

OpenSS7 repositries support apt(8) repositorie digests and signatures.

7.2.3 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 dependent on neither the Linux kernel version, nor the STREAMS package. For example, the source package ‘strinet-source-0.9.2.7-1.7.2.noarch.rpm’, is not dependent on kernel nor STREAMS package.

All of the following kernel and STREAMS independent RPM are required for your architecture. Binary RPMs listed here are for example only: additional binary RPMs are available from the downloads site.

Configuration and Installation

To configure, build and install the Debian DEB, See Configuring the Debian DEB.

7.2.5 Downloading the Source RPM

If you cannot obtain a binary RPM for your architecture, or would like to roll you own binary RPM, download the following source RPM.

strinet-0.9.2.7-1.src.rpm
This is the source RPM for the package. From this source RPM it is possible to build binary RPM for any supported architecture and for any 2.4 or 2.6 kernel, for either Linux STREAMS or Linux Fast-STREAMS.
Configuration

To configure the source RPM, See Configuring the Source RPM.

7.2.6 Downloading the Debian DSC

If you cannot obtain a binary DEB for your architecture, or would like to roll your own DEB, download the following Debian DSC.

strinet_0.9.2.7-0.dsc
strinet_0.9.2.7-0.tar.gz
This is the Debian DSC for the package. From this Debian DSC it is possible to build binary DEB for any supported architecture and for any 2.4 or 2.6 kernel, for either Linux STREAMS or Linux Fast-STREAMS.
Configuration

To configure the source RPM, See Configuring the Debian DSC.

7.2.7 Downloading the Tar Ball

For non-rpm(1) and non-dpkg(1) architectures, download the tarball as follows:

strinet-0.9.2.7.tar.gz
strinet-0.9.2.7.tar.bz2
These are the tar(1) balls for the release. These tar(1) balls contain the autoconf(1) distribution which includes all the source necessary for building and installing the package. These tarballs will even build Source RPM and Binary RPM on rpm(1) architectures and Debian DSC and DEB on dpkg(1) architectures.

The tar ball may be downloaded easily with wget(1) as follows:

     % wget http://www.openss7.org/strinet-0.9.2.7.tar.bz2

or

     % wget http://www.openss7.org/strinet-0.9.2.7.tar.gz

Note that you will need an OpenSS7 Project user name and password to download release candidates (which are only available to subscribers and sponsors of the OpenSS7 Project).

Unpacking the Archive

After downloading one of the tar balls, unpack the archive using one of the following commands:

     % wget http://www.openss7.org/strinet-0.9.2.7.tar.gz
     % tar -xzvf strinet-0.9.2.7.tar.gz

or

     % wget http://www.openss7.org/strinet-0.9.2.7.tar.bz2
     % tar -xjvf strinet-0.9.2.7.tar.bz2

Either will create a subdirectory name strinet-0.9.2.7 containing all of the files and subdirectories for the strinet package.

Configuration

To configure and install the tar ball, See Configuring the Tar Ball.

7.2.8 Downloading from CVS

If you are a subscriber or sponsor of The OpenSS7 Project with CVS archive access privileges then you can download release, mid-release or release candidate versions of the strinet package from the project CVS archive.

The OpenSS7 INET Networking package is located in the strinet module of /var/cvs. For release tag information, see Releases.

To access the archive from the project CVS pserver, use the following commands to check out a version from the archive:

     % export CVSROOT='-d:pserver:username@cvs.openss7.com:2401/var/cvs'
     % cvs login
     Password: *********
     % cvs co -r strinet_0.9.2.7 strinet
     % cvs logout

It is, of course, possible to check out by date or by other criteria. For more information, see cvs(1).

Preparing the CVS Working Directory

Although public releases of the strinet package do not require reconfiguration, creating a configurable directory from the CVS archive requires tools not normally distributed with the other releases.

The build host requires the following GNU tools:

  • m4 1.4.12
  • autoconf 2.63
  • automake 1.10.1
  • libtool 2.2.4
  • gettext 0.17
  • flex 2.5.33
  • bison 2.3

Most desktop development GNU/Linux distributions wil have these tools; however, some non-development or server-style installations might not and they must be installed separately.50

Also, these tools can be acquired from the FSF website in the free software directory, and also at the following locations:

It should be stressed that, in particular, the autoconf(1), and automake(1), must be at version releases 2.63 and 1.10.1. The versions normally distributed in some mainstream GNU/Linux distributions are, in fact, much older than these versions.51 GNU version of these packages configured and installed to default directories will install in /usr/local/ allowing them to coexist with distribution installed versions.

For building documentation, the build host also requires the following documentation tools:

  • gs 6.51 or ghostscript 6.51, or newer.
  • tetex 3.0 or texlive 2007, or newer.
  • texinfo 4.13a or newer.
  • transfig 3.2.3d or newer.
  • imagemagick 5.3.8 or ImageMagick 5.3.8, or newer.
  • groff 1.17.2 or newer.
  • gnuplot 3.7 or newer.
  • latex2html 1.62 or newer.

Most desktop GNU/Linux distributions will have these tools; however, some server-style installations (e.g. Ubuntu-server, SLES 9 or Fedora 6 or 7) will not and they must be installed separately.52

Note that texinfo 4.12 must not be used as it breaks the build process.

For uncooked manual pages, the entire groff(1) package is required on older Debian and Ubuntu systems (the base package did not include grefer(1) which is used extensively by uncooked manual pages). The following will get what you need on older systems:

     Debian: % apt-get install groff_ext
     Ubuntu: % apt-get install groff

On newer systems, simply:

     % apt-get install groff

In addition, the build host requires a complete tool chain for compiling for the target host, including kernel tools such as genksyms(8) and others.

If you wish to package rpms on an rpm(1) system, or debs on a dpkg(1) system, you will need the appropriate tool chain. Systems based on rpm(1) typically have the necessary tool chain available, however, dpkg(1) systems do not. The following on a Debian or Ubuntu system will get what you need:

     % apt-get install debhelper
     % apt-get install fakeroot

To generate a configuration script and the necessary scriptlets required by the GNU autoconf(1) system, execute the following commands on the working directory:

     % autoreconf -fiv strinet

where, strinet is the name of the directory to where the working copy was checked out under the previous step. This command generates the configure script and other missing pieces that are normally distributed with the release Tar Balls, SRPMs and DSCs.

Make sure that ‘autoreconf --version’ returns ‘2.63’. Otherwise, you may need to perform something like the following:

     % PATH="/usr/local/bin:$PATH"
     % autoreconf -fiv strinet

After reconfiguring the directory, the package can then be configured and built using the same instructions as are used for the Tar Ball, see Configuring the Tar Ball, and Building from the Tar Ball.

Do note, however, that make(1) will rebuild the documentation that is normally released with the package. Additional tools may be necessary for building the documentation. To avoid building and installing the documentation, use the --disable-devel or --disable-docs option to configure described in Configuring the Tar Ball.

When configuring the package in a working directory and while working a change-compile-test cycle that involves configuration macros or documentation, I find it of great advantage to invoke the GNU configure options --enable-maintainer-mode, --enable-dependency-tracking and --disable-devel. The first of these three options will add maintainer-specific targets to any generated Makefile, the second option will invoke automatic dependency tracking within the Makefile so rebuilds after changes to macro, source or documentation files will be automatically rebuilt; and the last option will suppress rebuilding and reinstalling documentation manual pages and header files. Header files will still be available under the /usr/src directory.

7.3.3 Configuring the Source RPM

When building from the source RPM (see Building from the Source RPM), the rebuild process uses a number of macros from the user's .rpmmacros file as described in rpm(8).

Following is an example of the ~/.rpmmacros file that I use for rebuilding RPMS:

     #
     # RPM macros for building rpms
     #

When building from the source RPM (see Building from the Source RPM), it is possible to pass a number of additional configuration options to the rpmbuild(1) process.

The additional configuration options are described below.

Note that distributions that use older versions of rpm do not have the --with or --without options defined. To achieve the same effect as:

     --with someparm=somearg

do:

     --define "_with_someparm --with-someparm=somearg"

This is a generic description of common rpmbuild(1) options. Not all rpmbuild(1) options are applicable to all SRPMs. Options that are kernel module specific are only applicable to SRPMs that build kernel modules. STREAMS options are only applicable to SRPMs that provide or require STREAMS.

--define "_kversion $PACKAGE_KVERSION"
Specifies the kernel version other than the running kernel for which to build. If _kversion is not defined when rebuilding, the environment variable PACKAGE_KVERSION is used. If the environment variable PACKAGE_KVERSION is not defined, then the version of the running kernel (i.e. discovered with ‘uname -r’) is used as the target version for kernel-dependent packages. This option can also be defined in an .rpmspec file using the macro name ‘_kversion’.
--with checks
--without checks
Enable or disable preinstall checks. Each packages supports a number of preinstall checks that can be performed by invoking the ‘check’ target with automake(1). These currently consist of checking each kernel module for unresolved kernel symbols, checking for documentation for exported kernel module symbols, checking for documentation for exported library symbols, checking for standard options for build and installable programs, checking for documentation for built and installable programs. Normally these checks are only run in maintainer mode, but can be enabled and disabled with this option.
--with k-optimize=HOW
--without k-optimize
Specify ‘HOW’ optimization, normal, size, speed or quick. size compiles kernel modules -Os, speed compiles kernel modules -O3, and quick compiles kernel modules -O0. The default is normal. Use with care.
--with cooked-manpages
--without cooked-manpages
Some systems do not like grefer(1) references in manual pages.55 This option will cook soelim(1), refer(1), tbl(1) and pic(1) commands from the manual pages and also strip groff(1) comments. The default is to leave manual pages uncooked: they are actually smaller that way.
--with public
--without public
Release public packages or private packages. This option has no effect on the strinet package. The default is to release public packages.
--with k-debug
--without k-debug
Specifies whether kernel debugging is to be performed on the build kernel modules. Mutually exclusive with test and safe below. This has the effect of removing static and inline attributes from functions and invoking all debugging macros in the code. The default is to not perform kernel debugging.
--with k-test
--without k-test
Specifies whether kernel testing is to be performed. Mutually exclusive with debug above and safe below. This has the effect of removing static and inline attributes from functions and invoking most debugging macros in the code. The default is to not perform kernel testing.
--with k-safe
--without k-safe
Specifies whether kernel saftey is to be performed. Mutually exclusive with debug and test above. This has the effect of invoking some more pedantic assertion macros in the code. The default is not to apply kernel safety.
--with k-inline
--without k-inline
Specifies whether kernel inline functions are to be placed inline. This has the effect of adding the -finline-functions flag to CFLAGS for compiling kernel modules. Linux 2.4 kernels are normally compiled -O2 which does not respect the inline directive. This compiles kernel modules with -finline-functions to get closer to -O3 optimization. For better optimization controls, See Configuring the Tar Ball.
--with k-modversions
--without k-modversions
Specifies whether kernel symbol versions are to be applied to symbols exported by package kernel modules. The default is to version exported module symbols. This package does not export symbols so this option has no effect.
--with devfs
--without devfs
Specifies whether the build is for a device file system daemon enabled system with autoloading, or not. The default is to build for devfsd(1) autoloading when CONFIG_DEVFS_FS is defined in the target kernel. The ‘rebuild’ target uses this option to signal to the RPM spec file that the ‘dev’ subpackage need not be built. This option does not appear when the package has no devices.
--with devel
--without devel
Specifies whether to build development environment packages such as those that include header files, static libraries, manual pages and texinfo(1) documentation. The default is to build development environment packages. This option can be useful when building for an embedded target where only the runtime components are desired.
--with docs
--without docs
Specifies whether to build and install major documentation such manual pages and texinfo(1) documentation. The default is to build and install documentation. This option can be useful when building for an embedded target where only the runtime and static compile components are desired, but not major documentation. This option does not override the setting of --without devel.
--with tools
--without tools
Specifies whether user space packages are to be built. The default is to build user space packages. This option can be useful when rebuilding for multiple architectures and target kernels. The ‘rebuildautomake(1) target uses this feature when rebuilding for all available architectures and kernels, to rebuild user packages once per architecture instead of once per kernel.
--with modules
--without modules
Specifies whether kernel modules packages are to be built. The default is to build kernel module packages. This option can be useful when rebuilding for multiple architectures and target kernels. The ‘rebuildautomake(1) target uses this feature to rebuild for all available architectures and kernels.
--with lis
--without lis
Specifies that the package is to be rebuilt against Linux STREAMS. The default is to automatically identify whether LiS or streams is loaded on the build system and build accordingly.
--with lfs
--without lfs
Specifies that the package is to be rebuilt against Linux Fast-STREAMS. The default is to automatically identify whether LiS or streams is loaded on the build system and build accordingly.

In general, the default values of these options are sufficient for most purposes and no options need be provided when rebuilding the Source RPMs.

7.3.4 Configuring the Debian DSC

The Debian DSC can be configured by passing options in the environment variable BUILD_DEBOPTIONS. The options placed in this variable take the same form as those passed to the configure script, See Configuring the Tar Ball. For an example, See Building from the Debian DSC.

7.3.5 Configuring the Tar Ball

All of the normal GNU autoconf(1) configuration options and environment variables apply. Additional options and environment variables are provided to tailor or customize the build and are described below.

7.3.5.1 Configure Options

This is a generic description of common configure options that are in addition to those provided by autoconf(1), automake(1), libtool(1) and gettext(1).

Not all configure options are applicable to all release packages. Options that are kernel module specific are only applicable to release packages that build kernel modules. STREAMS options are only applicable to release packages that provide or require STREAMS.

Following are the additional configure options, their meaning and use:

--enable-checks
--disable-checks
Enable or disable preinstall checks. Each release package supports a number of preinstall checks that can be performed by invoking the ‘check’ target with make(1). These currently consist of checking each kernel module for unresolved kernel symbols, checking for documentation for exported kernel module symbols, checking for documentation for exported library symbols, checking for standard options for build and installable programs, checking for documentation for built and installable programs. Normally these checks are only run in maintainer mode, but can be enabled and disabled with this option.
--enable-autotest
--disable-autotest
Enable or disable pre- and post-installation testing. Each release package supports a number of autotest test suites that can be performed by invoking the ‘installcheck’ target with make(1). These currently consist of running installed modules, commands and binaries against a number of specific test cases. Normally these checks are only run in maintainer mode, but can be enabled and disabled with this option.
--disable-compress-manpages
Compress manual pages with ‘gzip -9’ or ‘bzip2 -9’ or leave them uncompressed. The default is to compress manual pages with ‘gzip -9’ or ‘bzip2 -9’ if a single compressed manual page exists in the target installation directory (--mandir). This disables automatic compression.
--disable-public
Disable public release. This option is not usable on public releases and only has a usable effect on OpenSS7 INET Networking when the package is acquired from CVS. In particular, the STREAMS SS7/VoIP/ISDN/SIGTRAN Stacks (strss7-0.9a.8) release package has a large number of non-public components. Specifying this option will cause the package to build and install all private release components in addition to the public release components. This option affects all release packages. Most release packages do not have private release components.
--disable-initscripts
Disables the installation of init scripts. The default is to configure and install init scripts and their associated configuration files.

Although the default is to install init scripts, installation attempts to detect a System V init script configuration, and if one is not found, the init scripts are installed into the appropriate directories, but the symbolic links to the run level script directories are not generated and the script is not invoked. Therefore, it is safe to leave this option unchanged, even on distributions that do not support System V init script layout.

--disable-32bit-libs
Disables the build and install of 32-bit compatibility libraries and test binaries on 64-bit systems that support 32-bit compatibility. The default is to build and install 32-bit compatibility libraries and test binaries. This option can be usefule when configuring for an embedded target where only native shared libraries and binaries are desired.
--disable-devel
Disables the installation of development environment components such as header files, static libraries, manual pages and texinfo(1) documentation. The default is to install development environment components. This option can be useful when configuring for an embedded target where only the runtime components are desired, or when performing a edit-compile-test cycle.
--disable-docs
Disables the build and installation of major documentation such manual pages and texinfo(1) documentation. The default is to build and install documentation. This option can be useful when building for an embedded target where only the runtime and static compile components are desired, but not major documentation. This option does not override the setting of --disable-devel.
--enable-tools
Specifies whether user space programs and libraries are to be built and installed. The default is to build and install user space programs and libraries. This option can be useful when rebuilding for multiple architectures and target kernels, particularly under rpm(1) or dpkg(1). The ‘rebuildautomake(1) target uses this feature when rebuilding RPMs for all available architectures and kernels, to rebuild user packages once per architecture instead of once per kernel.
--enable-modules
Specifies whether kernel modules are to be built and installed. The default is to build and install kernel modules. This option can be useful when rebuilding for multiple architectures and target kernels, particularly under rpm(1) or dpkg(1). The ‘rebuildautomake(1) target uses this feature to rebuild for all available architectures and kernels. This option has no effect for release packages that do not provide kernel modules.
--enable-arch
Specifies whether architectural dependent package components are to be built and installed. This option can be useful when rebuilding for multiple architectures and target kernels, particularly under dpkg(1). The default is to configure, build and install architecture dependent package components. This option has no effect for release packages that do not provide architecture dependent components.
--enable-indep
Specifies whether architecture independent package components are to be built and installed. This option can be useful when rebuilding for multiple architectures and target kernels, particularly under dpkg(1). The default is to configure, build and install architecture independent package components. This options has no effect for release packages that do not provide architecture independent components.
--enable-k-inline
Enable kernel inline functions. Most Linux kernels build without -finline-functions. This option adds the -finline-functions and -Winline flags to the compilation of kernel modules. Use with care. This option has no effect for release packages that do not provide kernel modules.
--enable-k-safe
Enable kernel module run-time safety checks. Specifies whether kernel safety is to be performed. This option is mutually exclusive with --enable-k-test and --enable-k-debug below. This has the effect of invoking some more pedantic assertion macros in the code. The default is not to apply kernel safety. This option has no effect for release packages that have are no kernel modules.
--enable-k-test
Enable kernel module run-time testing. Specifies whether kernel testing is to be performed. This option is mutually exclusive with --enable-k-safe above and --enable-k-debug below. This has the effect of remove static and inline attributes from functions and invoking most non-performance affecting debugging macros in the code. The default is not to perform kernel testing. This option has no effect for release packages that do not provide kernel modules.
--enable-k-debug
Enable kernel module run-time debugging. Specifies whether kernel debugging is to be performed. This option is mutually exclusive with --enable-k-safe and --enable-k-test above. This has the effect of removing static and inline attributes from functions and invoking all debugging macros in the code (including performance-affecting debug macros). The default is to not perform kernel debugging. This option has no effect for release packages that do not provide kernel modules.
--disable-k-modversions
Disable module versions on strinet symbols. Specifies whether kernel symbol versions are to be used on symbols exported from built strinet modules. The default is to provide kernel symbol versions on all exported symbols. This option has no effect for release packages that do not provide kernel modules.
--enable-devfs
--disable-devfs
Specifies whether the build is for a device file system daemon enabled system with autoloading, or not. The default is to build for devfsd(8) autoloading when CONFIG_DEVFS_FS is defined in the target kernel. The ‘reuildautomake(1) target uses this option to signal to the RPM spec file that the ‘dev’ subpackage need not be built. This option has no effect for release packages that do not provide devices.
--with-gpg-user=GNUPGUSER
Specify the gpg(1)GNUPGUSER’ for signing RPMs and tarballs. The default is the content of the environment variable GNUPGUSER. If unspecified, the gpg(1) program will normally use the user name of the account invoking the gpg(1) program. For building source RPMs, the RPM macro ‘_gpg_name’ will override this setting.
--with-gpg-home=GNUPGHOME
Specify the ‘GNUPGHOME’ directory for signing RPMs and tarballs. The default is the user's ~/.gpg directory. For building source RPMs, the RPM macro ‘_gpg_path’ will override this setting.
--with-pkg-epoch=EPOCH
Specifies the epoch for the package. This is neither used for rpm(1) nor dpkg(1) packages, it applies to the tarball release as a whole. The default is the contents of the .pkgepoch file in the release package source directory or, if that file does not exist, zero (0).
--with-pkg-release=RELEASE
Specifies the release for the package. This is neither used for rpm(1) nor dpkg(1) packages, it applies to the tarball release as a whole. The default is the contents of the .pkgrelease file in the release package source directory or, if that file does not exist, one (1). This is the number after the last point in the package version number.
--with-pkg-distdir=DIR
Specifies the distribution directory for the package. This is used by the maintainer for building distributions of tarballs. This is the directory into which archives are copied for distribution. The default is the top build directory.
--with-cooked-manpages
Convert manual pages to remove macro dependencies and grefer(1) references. Some systems do not like grefer(1) references in manual pages.56 This option will cook soelim(1), refer(1), tbl(1) and pic(1) commands from the manual pages and also strip groff(1) comments. The default is to leave manual pages uncooked (they are actually smaller that way).
--with-rpm-epoch=PACKAGE_EPOCH
Specify the ‘PACKAGE_EPOCH’ for the RPM spec file. The default is to use the RPM epoch contained in the release package file .rpmepoch.
--with-rpm-release=PACKAGE_RPMRELEASE
Specify the ‘PACKAGE_RPMRELEASE’ for the RPM spec file. The default is to use the RPM release contained in the release package file .rpmrelease.
--with-rpm-extra=PACKAGE_RPMEXTRA
Specify the ‘PACKAGE_RPMEXTRA’ extra release information for the RPM spec file. The default is to use the RPM extra release information contained in the release package file .rpmextra. Otherwise, this value will be determined from automatic detection of the RPM distribution.
--with-rpm-topdir=PACKAGE_RPMTOPDIR
Specify the ‘PACKAGE_RPMTOPDIR’ top directory for RPMs. If specified with a null ‘PACKAGE_RPMTOPDIR’, the default directory for the RPM distribution will be used. If this option is not provided on the command line, the top build directory will be used as the RPM top directory as well.
--with-deb-epoch=EPOCH
Specify the ‘PACKAGE_DEBEPOCH’ for the DEB control file. The default is to use the DEB epoch contained in the release package file .debepoch.
--with-deb-release=RELEASE
Specify the ‘PACKAGE_DEBRELEASE’ for the DEB control file. The default is to use the DEB release contained in the release package file .debrelease.
--with-deb-topdir=DIR
Specify the ‘PACKAGE_DEBTOPDIR’ top directory for DEBs. If specified with a null ‘PACKAGE_DEBTOPDIR’, the default directory for the DEB distribution will be used. If this option is not provided on the command line, the top build directory will be used as the DEB top directory as well.
--with-k-release=PACKAGE_KRELEASE
Specify the ‘PACKAGE_KRELEASE’ release of the Linux kernel for which the build is targeted. When not cross compiling, if this option is not set, the build will be targeted at the kernel running in the build environment (e.g., ‘uname -r’). When cross-compiling this option must be specified or the configure script will generate an error and terminate.
--with-k-linkage=PACKAGE_KLINKAGE
Specify the ‘PACKAGE_KLINKAGE’ for kernel module linkage. This can be one of the following:
  • loadable’ – loadable kernel modules
  • linkable’ – linkable kernel objects
The default is to build loadable kernel modules.
--with-k-modules=K-MODULES-DIR
Specify the ‘K-MODULES-DIR’ directory to which kernel modules will be installed. The default is based on the option --with-k-release, --with-k-prefix and --with-k-rootdir. The default is DESTDIR/K-MODULES-DIR which is typically DESTDIR/lib/modules/PACKAGE_KRELEASE/. This directory is normally located by the configure script and need only be provided for special cross-build environmen
