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.

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 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 separate 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". - |
