INSTALLATION ON THE NETWARE PLATFORM
|
|
------------------------------------
|
|
|
|
Notes about building OpenSSL for NetWare.
|
|
|
|
|
|
BUILD PLATFORM:
|
|
---------------
|
|
The build scripts (batch files, perl scripts, etc) have been developed and
|
|
tested on W2K. 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 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".
|
|
|
