The scripts should run fine on other Windows platforms +(NT, Win9x, WinXP) but they have not been tested. They may require some +modifications. + + +Supported NetWare Platforms - NetWare 5.x, NetWare 6.x: +------------------------------------------------------- +OpenSSL can either use the WinSock interfaces introduced in NetWare 5, +or the BSD socket interface. Previous versions of NetWare, 4.x and 3.x, +are only supported if OpenSSL is build for CLIB and BSD sockets; +WinSock builds only support NetWare 5 and up. + +On NetWare there are two c-runtime libraries. There is the legacy CLIB +interfaces and the newer LIBC interfaces. Being ANSI-C libraries, the +functionality in CLIB and LIBC is similar but the LIBC interfaces are built +using Novell Kernal Services (NKS) which is designed to leverage +multi-processor environments. + +The NetWare port of OpenSSL can be configured to build using CLIB or LIBC. +The CLIB build was developed and tested using NetWare 5.0 sp6.0a. The LIBC +build was developed and tested using the NetWare 6.0 FCS. + +The necessary LIBC functionality ships with NetWare 6. However, earlier +NetWare 5.x versions will require updates in order to run the OpenSSL LIBC +build (NetWare 5.1 SP8 is known to work). + +As of June 2005, the LIBC build can be configured to use BSD sockets instead +of WinSock sockets. Call Configure (usually through netware\build.bat) using +a target of "netware-libc-bsdsock" instead of "netware-libc". + +As of June 2007, support for CLIB and BSD sockets is also now available +using a target of "netware-clib-bsdsock" instead of "netware-clib"; +also gcc builds are now supported on both Linux and Win32 (post 0.9.8e). + +REQUIRED TOOLS: +--------------- +Based upon the configuration and build options used, some or all of the +following tools may be required: + +* Perl for Win32 - required (http://www.activestate.com/ActivePerl) + Used to run the various perl scripts on the build platform. + +* Perl 5.8.0 for NetWare v3.20 (or later) - required + (http://developer.novell.com) Used to run the test script on NetWare + after building. + +* Compiler / Linker - required: + Metrowerks CodeWarrior PDK 2.1 (or later) for NetWare (commercial): + Provides command line tools used for building. + Tools: + mwccnlm.exe - C/C++ Compiler for NetWare + mwldnlm.exe - Linker for NetWare + mwasmnlm.exe - x86 assembler for NetWare (if using assembly option) + + gcc / nlmconv Cross-Compiler, available from Novell Forge (free): + http://forge.novell.com/modules/xfmod/project/?aunixnw + +* Assemblers - optional: + If you intend to build using the assembly options you will need an + assembler. Work has been completed to support two assemblers, Metrowerks + and NASM. However, during development, a bug was found in the Metrowerks + assembler which generates incorrect code. Until this problem is fixed, + the Metrowerks assembler cannot be used. + + mwasmnlm.exe - Metrowerks x86 assembler - part of CodeWarrior tools. + (version 2.2 Built Aug 23, 1999 - not useable due to code + generation bug) + + nasmw.exe - Netwide Assembler NASM + version 0.98 was used in development and testing + +* Make Tool - required: + In order to build you will need a make tool. Two make tools are + supported, GNU make (gmake.exe) or Microsoft nmake.exe. + + make.exe - GNU make for Windows (version 3.75 used for development) + http://gnuwin32.sourceforge.net/packages/make.htm + + nmake.exe - Microsoft make (Version 6.00.8168.0 used for development) + http://support.microsoft.com/kb/132084/EN-US/ + +* Novell Developer Kit (NDK) - required: (http://developer.novell.com) + + CLIB - BUILDS: + + WinSock2 Developer Components for NetWare: + For initial development, the October 27, 2000 version was used. + However, future versions should also work. + + NOTE: The WinSock2 components include headers & import files for + NetWare, but you will also need the winsock2.h and supporting + headers (pshpack4.h, poppack.h, qos.h) delivered in the + Microsoft SDK. Note: The winsock2.h support headers may change + with various versions of winsock2.h. Check the dependencies + section on the NDK WinSock2 download page for the latest + information on dependencies. These components are unsupported by + Novell. They are provided as a courtesy, but it is strongly + suggested that all development be done using LIBC, not CLIB. + + As of June 2005, the WinSock2 components are available at: + http://forgeftp.novell.com//ws2comp/ + + + NLM and NetWare libraries for C (including CLIB and XPlat): + If you are going to build a CLIB version of OpenSSL, you will + need the CLIB headers and imports. The March, 2001 NDK release or + later is recommended. + + Earlier versions should work but haven't been tested. In recent + versions the import files have been consolidated and function + names moved. This means you may run into link problems + (undefined symbols) when using earlier versions. The functions + are available in earlier versions, but you will have to modifiy + the make files to include additional import files (see + openssl\util\pl\netware.pl). + + + LIBC - BUILDS: + + Libraries for C (LIBC) - LIBC headers and import files + If you are going to build a LIBC version of OpenSSL, you will + need the LIBC headers and imports. The March 14, 2002 NDK release or + later is required. + + NOTE: The LIBC SDK includes the necessary WinSock2 support. + It is not necessary to download the WinSock2 NDK when building for + LIBC. The LIBC SDK also includes the appropriate BSD socket support + if configuring to use BSD sockets. + + +BUILDING: +--------- +Before building, you will need to set a few environment variables. You can +set them manually or you can modify the "netware\set_env.bat" file. + +The set_env.bat file is a template you can use to set up the path +and environment variables you will need to build. Modify the +various lines to point to YOUR tools and run set_env.bat. + + netware\set_env.bat <target> [compiler] + + target - "netware-clib" - CLIB NetWare build + - "netware-libc" - LIBC NetWare build + + compiler - "gnuc" - GNU GCC Compiler + - "codewarrior" - MetroWerks CodeWarrior (default) + +If you don't use set_env.bat, you will need to set up the following +environment variables: + + PATH - Set PATH to point to the tools you will use. + + INCLUDE - The location of the NDK include files. + + CLIB ex: set INCLUDE=c:\ndk\nwsdk\include\nlm + LIBC ex: set INCLUDE=c:\ndk\libc\include + + PRELUDE - The absolute path of the prelude object to link with. For + a CLIB build it is recommended you use the "clibpre.o" files shipped + with the Metrowerks PDK for NetWare. For a LIBC build you should + use the "libcpre.o" file delivered with the LIBC NDK components. + + CLIB ex: set PRELUDE=c:\ndk\nwsdk\imports\clibpre.o + LIBC ex: set PRELUDE=c:\ndk\libc\imports\libcpre.o + + IMPORTS - The locaton of the NDK import files. + + CLIB ex: set IMPORTS=c:\ndk\nwsdk\imports + LIBC ex: set IMPORTS=c:\ndk\libc\imports + + +In order to build, you need to run the Perl scripts to configure the build +process and generate a make file. There is a batch file, +"netware\build.bat", to automate the process. + +Build.bat runs the build configuration scripts and generates a make file. +If an assembly option is specified, it also runs the scripts to generate +the assembly code. Always run build.bat from the "openssl" directory. + + netware\build [target] [debug opts] [assembly opts] [configure opts] + + target - "netware-clib" - CLIB NetWare build (WinSock Sockets) + - "netware-clib-bsdsock" - CLIB NetWare build (BSD Sockets) + - "netware-libc" - LIBC NetWare build (WinSock Sockets) + - "netware-libc-bsdsock" - LIBC NetWare build (BSD Sockets) + + debug opts - "debug" - build debug + + assembly opts - "nw-mwasm" - use Metrowerks assembler + "nw-nasm" - use NASM assembler + "no-asm" - don't use assembly + + configure opts- all unrecognized arguments are passed to the + perl 'configure' script. See that script for + internal documentation regarding options that + are available. + + examples: + + CLIB build, debug, without assembly: + netware\build.bat netware-clib debug no-asm + + LIBC build, non-debug, using NASM assembly, add mdc2 support: + netware\build.bat netware-libc nw-nasm enable-mdc2 + + LIBC build, BSD sockets, non-debug, without assembly: + netware\build.bat netware-libc-bsdsock no-asm + +Running build.bat generates a make file to be processed by your make +tool (gmake or nmake): + + CLIB ex: gmake -f netware\nlm_clib_dbg.mak + LIBC ex: gmake -f netware\nlm_libc.mak + LIBC ex: gmake -f netware\nlm_libc_bsdsock.mak + + +You can also run the build scripts manually if you do not want to use the +build.bat file. Run the following scripts in the "\openssl" +subdirectory (in the order listed below): + + perl configure no-asm [other config opts] [netware-clib|netware-libc|netware-libc-bsdsock] + configures no assembly build for specified netware environment + (CLIB or LIBC). + + perl util\mkfiles.pl >MINFO + generates a listing of source files (used by mk1mf) + + perl util\mk1mf.pl no-asm [other config opts] [netware-clib|netware-libc|netware-libc-bsdsock >netware\nlm.mak + generates the makefile for NetWare + + gmake -f netware\nlm.mak + build with the make tool (nmake.exe also works) + +NOTE: If you are building using the assembly option, you must also run the +various Perl scripts to generate the assembly files. See build.bat +for an example of running the various assembly scripts. You must use the +"no-asm" option to build without assembly. The configure and mk1mf scripts +also have various other options. See the scripts for more information. + + +The output from the build is placed in the following directories: + + CLIB Debug build: + out_nw_clib.dbg - static libs & test nlm(s) + tmp_nw_clib.dbg - temporary build files + outinc_nw_clib - necessary include files + + CLIB Non-debug build: + out_nw_clib - static libs & test nlm(s) + tmp_nw_clib - temporary build files + outinc_nw_clib - necesary include files + + LIBC Debug build: + out_nw_libc.dbg - static libs & test nlm(s) + tmp_nw_libc.dbg - temporary build files + outinc_nw_libc - necessary include files + + LIBC Non-debug build: + out_nw_libc - static libs & test nlm(s) + tmp_nw_libc - temporary build files + outinc_nw_libc - necesary include files + + +TESTING: +-------- +The build process creates the OpenSSL static libs ( crypto.lib, ssl.lib, +rsaglue.lib ) and several test programs. You should copy the test programs +to your NetWare server and run the tests. + +The batch file "netware\cpy_tests.bat" will copy all the necessary files +to your server for testing. In order to run the batch file, you need a +drive mapped to your target server. It will create an "OpenSSL" directory +on the drive and copy the test files to it. CAUTION: If a directory with the +name of "OpenSSL" already exists, it will be deleted. + +To run cpy_tests.bat: + + netware\cpy_tests [output directory] [NetWare drive] + + output directory - "out_nw_clib.dbg", "out_nw_libc", etc. + NetWare drive - drive letter of mapped drive + + CLIB ex: netware\cpy_tests out_nw_clib m: + LIBC ex: netware\cpy_tests out_nw_libc m: + + +The Perl script, "do_tests.pl", in the "OpenSSL" directory on the server +should be used to execute the tests. Before running the script, make sure +your SEARCH PATH includes the "OpenSSL" directory. For example, if you +copied the files to the "sys:" volume you use the command: + + SEARCH ADD SYS:\OPENSSL + + +To run do_tests.pl type (at the console prompt): + + perl \openssl\do_tests.pl [options] + + options: + -p - pause after executing each test + +The do_tests.pl script generates a log file "\openssl\test_out\tests.log" +which should be reviewed for errors. Any errors will be denoted by the word +"ERROR" in the log. + +DEVELOPING WITH THE OPENSSL SDK: +-------------------------------- +Now that everything is built and tested, you are ready to use the OpenSSL +libraries in your development. + +There is no real installation procedure, just copy the static libs and +headers to your build location. The libs (crypto.lib & ssl.lib) are +located in the appropriate "out_nw_XXXX" directory +(out_nw_clib, out_nw_libc, etc). + +The headers are located in the appropriate "outinc_nw_XXX" directory +(outinc_nw_clib, outinc_nw_libc). + +One suggestion is to create the following directory +structure for the OpenSSL SDK: + + \openssl + |- bin + | |- openssl.nlm + | |- (other tests you want) + | + |- lib + | | - crypto.lib + | | - ssl.lib + | + |- include + | | - openssl + | | | - (all the headers in "outinc_nw\openssl") + + +The program "openssl.nlm" can be very useful. It has dozens of +options and you may want to keep it handy for debugging, testing, etc. + +When building your apps using OpenSSL, define "NETWARE". It is needed by +some of the OpenSSL headers. One way to do this is with a compile option, +for example "-DNETWARE". + + + +NOTES: +------ + +Resource leaks in Tests +------------------------ +Some OpenSSL tests do not clean up resources and NetWare reports +the resource leaks when the tests unload. If this really bugs you, +you can stop the messages by setting the developer option off at the console +prompt (set developer option = off). Or better yet, fix the tests to +clean up the resources! + + +Multi-threaded Development +--------------------------- +The NetWare version of OpenSSL is thread-safe, however multi-threaded +applications must provide the necessary locking function callbacks. This +is described in doc\threads.doc. The file "openssl-x.x.x\crypto\threads\mttest.c" +is a multi-threaded test program and demonstrates the locking functions. + + +What is openssl2.nlm? +--------------------- +The openssl program has numerous options and can be used for many different +things. Many of the options operate in an interactive mode requiring the +user to enter data. Because of this, a default screen is created for the +program. However, when running the test script it is not desirable to +have a seperate screen. Therefore, the build also creates openssl2.nlm. +Openssl2.nlm is functionally identical but uses the console screen. +Openssl2 can be used when a non-interactive mode is desired. + +NOTE: There are may other possibilities (command line options, etc) +which could have been used to address the screen issue. The openssl2.nlm +option was chosen because it impacted only the build not the code. + + +Why only static libraries? +-------------------------- +Globals, globals, and more globals. The OpenSSL code uses many global +variables that are allocated and initialized when used for the first time. + +On NetWare, most applications (at least historically) run in the kernel. +When running in the kernel, there is one instance of global variables. +For regular application type NLM(s) this isn't a problem because they are +the only ones using the globals. However, for a library NLM (an NLM which +exposes functions and has no threads of execution), the globals cause +problems. Applications could inadvertently step on each other if they +change some globals. Even worse, the first application that triggers a +global to be allocated and initialized has the allocated memory charged to +itself. Now when that application unloads, NetWare will clean up all the +applicaton's memory. The global pointer variables inside OpenSSL now +point to freed memory. An abend waiting to happen! + +To work correctly in the kernel, library NLM(s) that use globals need to +provide a set of globals (instance data) for each application. Another +option is to require the library only be loaded in a protected address +space along with the application using it. + +Modifying the OpenSSL code to provide a set of globals (instance data) for +each application isn't technically difficult, but due to the large number +globals it would require substantial code changes and it wasn't done. Hence, +the build currently only builds static libraries which are then linked +into each application. + +NOTE: If you are building a library NLM that uses the OpenSSL static +libraries, you will still have to deal with the global variable issue. +This is because when you link in the OpenSSL code you bring in all the +globals. One possible solution for the global pointer variables is to +register memory functions with OpenSSL which allocate memory and charge it +to your library NLM (see the function CRYPTO_set_mem_functions). However, +be aware that now all memory allocated by OpenSSL is charged to your NLM. + + +CodeWarrior Tools and W2K +--------------------------- +There have been problems reported with the CodeWarrior Linker +(mwldnlm.exe) in the PDK 2.1 for NetWare when running on Windows 2000. The +problems cause the link step to fail. The only work around is to obtain an +updated linker from Metrowerks. It is expected Metrowerks will release +PDK 3.0 (in beta testing at this time - May, 2001) in the near future which +will fix these problems. + + +Makefile "vclean" +------------------ +The generated makefile has a "vclean" target which cleans up the build +directories. If you have been building successfully and suddenly +experience problems, use "vclean" (gmake -f netware\nlm_xxxx.mak vclean) and retry. + + +"Undefined Symbol" Linker errors +-------------------------------- +There have been linker errors reported when doing a CLIB build. The problems +occur because some versions of the CLIB SDK import files inadvertently +left out some symbols. One symbol in particular is "_lrotl". The missing +functions are actually delivered in the binaries, but they were left out of +the import files. The issues should be fixed in the September 2001 release +of the NDK. If you experience the problems you can temporarily +work around it by manually adding the missing symbols to your version of +"clib.imp". + |
