NOTES FOR THE HPE NONSTOP PLATFORM
|
||
|
|
==============================
|
||
|
|
|
||
|
|
Requirement details
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
In addition to the requirements and instructions listed
|
||
|
|
in [INSTALL.md](INSTALL.md), the following are required as well:
|
||
|
|
|
||
|
|
* The TNS/X platform supports hardware randomization.
|
||
|
|
Specify the `--with-rand-seed=rdcpu` option to the `./Configure` script.
|
||
|
|
This is recommended but not required. `egd` is supported at 3.0 but cannot
|
||
|
|
be used if FIPS is selected.
|
||
|
|
* The TNS/E platform does not support hardware randomization, so
|
||
|
|
specify the `--with-rand-seed=egd` option to the `./Configure` script.
|
||
|
|
|
||
|
|
About c99 compiler
|
||
|
|
------------------
|
||
|
|
|
||
|
|
The c99 compiler is required for building OpenSSL from source. While c11
|
||
|
|
may work, it has not been broadly tested. c99 is the only compiler
|
||
|
|
prerequisite needed to build OpenSSL 3.0 on this platform. You should also
|
||
|
|
have the FLOSS package installed on your system. The ITUGLIB FLOSS package
|
||
|
|
is the only FLOSS variant that has been broadly tested.
|
||
|
|
|
||
|
|
Threading Models
|
||
|
|
----------------
|
||
|
|
|
||
|
|
OpenSSL can be built either using the POSIX User Threads (PUT) threading model,
|
||
|
|
or with threading support disabled. Select the following build configuration
|
||
|
|
for each on the TNS/X (L-Series) platform:
|
||
|
|
|
||
|
|
* `nonstop-nsx` or default will select an unthreaded 32-bit build.
|
||
|
|
* `nonstop-nsx_64` selects an unthreaded 64-bit memory and file length build.
|
||
|
|
* `nonstop-nsx_put` selects the PUT build.
|
||
|
|
* `nonstop-nsx_64_put` selects the 64-bit memory and file length PUT build.
|
||
|
|
|
||
|
|
The SPT threading model is no longer supported as of OpenSSL 3.2.
|
||
|
|
|
||
|
|
### TNS/E Considerations
|
||
|
|
|
||
|
|
The TNS/E platform is build using the same set of builds specifying `nse`
|
||
|
|
instead of `nsx` in the set above.
|
||
|
|
|
||
|
|
You cannot build for TNS/E for FIPS, so you must specify the `no-fips`
|
||
|
|
option to `./Configure`.
|
||
|
|
|
||
|
|
Linking and Loading Considerations
|
||
|
|
----------------------------------
|
||
|
|
|
||
|
|
Because of how the NonStop Common Runtime Environment (CRE) works, there are
|
||
|
|
restrictions on how programs can link and load with OpenSSL libraries.
|
||
|
|
On current NonStop platforms, programs cannot both statically link OpenSSL
|
||
|
|
libraries and dynamically load OpenSSL shared libraries concurrently. If this
|
||
|
|
is done, there is a high probability of encountering a SIGSEGV condition
|
||
|
|
relating to `atexit()` processing when a shared library is unloaded and when
|
||
|
|
the program terminates. This limitation applies to all OpenSSL shared library
|
||
|
|
components.
|
||
|
|
|
||
|
|
A resolution to this situation is under investigation.
|
||
|
|
|
||
|
|
About Prefix and OpenSSLDir
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
Because there are many potential builds that must co-exist on any given
|
||
|
|
NonStop node, managing the location of your build distribution is crucial.
|
||
|
|
Keep each destination separate and distinct. Mixing any mode described in
|
||
|
|
this document can cause application instability. The recommended approach
|
||
|
|
is to specify the OpenSSL version and threading model in your configuration
|
||
|
|
options, and keeping your memory and float options consistent, for example:
|
||
|
|
|
||
|
|
* For 1.1 `--prefix=/usr/local-ssl1.1 --openssldir=/usr/local-ssl1.1/ssl`
|
||
|
|
* For 1.1 PUT `--prefix=/usr/local-ssl1.1_put --openssldir=/usr/local-ssl1.1_put/ssl`
|
||
|
|
|
||
|
|
As of 3.0, the NonStop configurations use the multilib attribute to distinguish
|
||
|
|
between different models:
|
||
|
|
|
||
|
|
* For 3.0 `--prefix=/usr/local-ssl3.0 --openssldir=/usr/local-ssl3.0/ssl`
|
||
|
|
|
||
|
|
The PUT model is placed in `${prefix}/lib-put` for 32-bit models and
|
||
|
|
`${prefix}/lib64-put` for 64-bit models.
|
||
|
|
|
||
|
|
Use the `_RLD_LIB_PATH` environment variable in OSS to select the appropriate
|
||
|
|
directory containing `libcrypto.so` and `libssl.so`. In GUARDIAN, use the
|
||
|
|
`=_RLD_LIB_PATH` search define to locate the GUARDIAN subvolume where OpenSSL
|
||
|
|
is installed.
|
||
|
|
|
||
|
|
Float Considerations
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
OpenSSL is built using IEEE Float mode by default. If you need a different
|
||
|
|
IEEE mode, create a new configuration specifying `tfloat-x86-64` (for Tandem
|
||
|
|
Float) or `nfloat-x86-64` (for Neutral Float).
|
||
|
|
|
||
|
|
Memory Models
|
||
|
|
-------------
|
||
|
|
|
||
|
|
The current OpenSSL default memory model uses the default platform address
|
||
|
|
model. If you need a different address model, you must specify the appropriate
|
||
|
|
c99 options for compile (`CFLAGS`) and linkers (`LDFLAGS`).
|
||
|
|
|
||
|
|
Cross Compiling on Windows
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
To configure and compile OpenSSL, you will need to set up a Cygwin environment.
|
||
|
|
The Cygwin tools should include bash, make, and any other normal tools required
|
||
|
|
for building programs.
|
||
|
|
|
||
|
|
Your `PATH` must include the bin directory for the c99 cross-compiler, as in:
|
||
|
|
|
||
|
|
export PATH=/cygdrive/c/Program\ Files\ \(x86\)/HPE\ NonStop/L16.05/usr/bin:$PATH
|
||
|
|
|
||
|
|
This should be set before Configure is run. For the c99 cross-compiler to work
|
||
|
|
correctly, you also need the `COMP_ROOT` set, as in:
|
||
|
|
|
||
|
|
export COMP_ROOT="C:\Program Files (x86)\HPE NonStop\L16.05"
|
||
|
|
|
||
|
|
`COMP_ROOT` needs to be in Windows form.
|
||
|
|
|
||
|
|
`Configure` must specify the `no-makedepend` option otherwise errors will
|
||
|
|
result when running the build because the c99 cross-compiler does not support
|
||
|
|
the `gcc -MT` option. An example of a `Configure` command to be run from the
|
||
|
|
OpenSSL directory is:
|
||
|
|
|
||
|
|
./Configure nonstop-nsx_64 no-makedepend --with-rand-seed=rdcpu
|
||
|
|
|
||
|
|
Do not forget to include any OpenSSL cross-compiling prefix and certificate
|
||
|
|
options when creating your libraries.
|
||
|
|
|
||
|
|
The OpenSSL test suite will not run on your workstation. In order to verify the
|
||
|
|
build, you will need to perform the build and test steps in OSS in your NonStop
|
||
|
|
server. You can also build under gcc and run the test suite for Windows but that
|
||
|
|
is not equivalent.
|
||
|
|
|
||
|
|
**Note:** In the event that you are attempting a FIPS-compliant cross-compile,
|
||
|
|
be aware that signatures may not match between builds done under OSS and under
|
||
|
|
cross-compiles as the compilers do not necessarily generate identical objects.
|
||
|
|
Anything and everything to do with FIPS is outside the scope of this document.
|
||
|
|
Refer to the FIPS security policy for more information.
|
||
|
|
|
||
|
|
The following build configurations have been successfully attempted at one
|
||
|
|
point or another. If you are successful in your cross-compile efforts, please
|
||
|
|
update this list:
|
||
|
|
|
||
|
|
- nonstop-nsx_64
|
||
|
|
- nonstop-nsx_64_put
|
||
|
|
|
||
|
|
**Note:** Cross-compile builds for TNS/E have not been attempted, but should
|
||
|
|
follow the same considerations as for TNS/X above.
|
||
|
|
|
||
|
|
Also see the NSDEE discussion below for more historical information.
|
||
|
|
|
||
|
|
Cross Compiling with NSDEE
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
**Note:** None of these builds have been tested by the platform maintainer and
|
||
|
|
are supplied for historical value. Please submit a Pull Request to OpenSSL
|
||
|
|
should these need to be adjusted.
|
||
|
|
|
||
|
|
If you are attempting to build OpenSSL with NSDEE, you will need to specify
|
||
|
|
the following variables. The following set of compiler defines are required:
|
||
|
|
|
||
|
|
# COMP_ROOT must be a full path for the build system (e.g. windows)
|
||
|
|
COMP_ROOT=$(cygpath -w /path/to/comp_root)
|
||
|
|
# CC must be executable by your shell
|
||
|
|
CC=/path/to/c99
|
||
|
|
|
||
|
|
### Optional Build Variables
|
||
|
|
|
||
|
|
DBGFLAG="--debug"
|
||
|
|
CIPHENABLES="enable-ssl3 enable-ssl3-method enable-weak-ssl-ciphers enable-rc4"
|
||
|
|
|
||
|
|
### Internal Known TNS/X to TNS/E Cross Compile Variables
|
||
|
|
|
||
|
|
The following definition is required if you are building on TNS/X for TNS/E
|
||
|
|
and have access to a TNS/E machine on your EXPAND network - with an example
|
||
|
|
node named `\CS3`:
|
||
|
|
|
||
|
|
SYSTEMLIBS="-L/E/cs3/usr/local/lib"
|
||
|
|
|
||
|
|
Version Procedure (VPROC) Considerations
|
||
|
|
----------------------------------------
|
||
|
|
|
||
|
|
If you require a VPROC entry for platform version identification, use the
|
||
|
|
following variables:
|
||
|
|
|
||
|
|
### For Itanium
|
||
|
|
|
||
|
|
OPENSSL_VPROC_PREFIX=T0085H06
|
||
|
|
|
||
|
|
### For x86
|
||
|
|
|
||
|
|
OPENSSL_VPROC_PREFIX=T0085L01
|
||
|
|
|
||
|
|
### Common Definition
|
||
|
|
|
||
|
|
export OPENSSL_VPROC=${OPENSSL_VPROC_PREFIX}_$(
|
||
|
|
. VERSION.dat
|
||
|
|
if [ -n "$PRE_RELEASE_TAG" ]; then
|
||
|
|
PRE_RELEASE_TAG="-$PRE_RELEASE_TAG"
|
||
|
|
fi
|
||
|
|
if [ -n "$BUILD_METADATA" ]; then
|
||
|
|
BUILD_METADATA="+$BUILD_METADATA"
|
||
|
|
fi
|
||
|
|
echo "$MAJOR.$MINOR.$PATCH$PRE_RELEASE_TAG$BUILD_METADATA" |\
|
||
|
|
sed -e 's/[-.+]/_/g'
|
||
|
|
)
|
||
|
|
|
||
|
|
Example Configure Targets
|
||
|
|
-------------------------
|
||
|
|
|
||
|
|
For OSS targets, the main DLL names will be `libssl.so` and `libcrypto.so`.
|
||
|
|
For GUARDIAN targets, DLL names will be `ssl` and `crypto`. The following
|
||
|
|
assumes that your PWD is set according to your installation standards.
