1NOTES FOR THE HPE NONSTOP PLATFORM
2==============================
3
4Requirement details
5-------------------
6
7In addition to the requirements and instructions listed
8in [INSTALL.md](INSTALL.md), the following are required as well:
9
10 * The TNS/X platform supports hardware randomization.
11   Specify the `--with-rand-seed=rdcpu` option to the `./Configure` script.
12   This is recommended but not required. `egd` is supported at 3.0 but cannot
13   be used if FIPS is selected.
14 * The TNS/E platform does not support hardware randomization, so
15   specify the `--with-rand-seed=egd` option to the `./Configure` script.
16
17About c99 compiler
18------------------
19
20The c99 compiler is required for building OpenSSL from source. While c11
21may work, it has not been broadly tested. c99 is the only compiler
22prerequisite needed to build OpenSSL 3.0 on this platform. You should also
23have the FLOSS package installed on your system. The ITUGLIB FLOSS package
24is the only FLOSS variant that has been broadly tested.
25
26Threading Models
27----------------
28
29OpenSSL can be built using unthreaded, POSIX User Threads (PUT), or Standard
30POSIX Threads (SPT). Select the following build configuration for each on
31the TNS/X (L-Series) platform:
32
33 * `nonstop-nsx` or default will select an unthreaded build.
34 * `nonstop-nsx_put` selects the PUT build.
35 * `nonstop-nsx_64_put` selects the 64 bit file length PUT build.
36 * `nonstop-nsx_spt_floss` selects the SPT build with FLOSS. FLOSS is
37   required for SPT builds because of a known hang when using SPT on its own.
38
39### TNS/E Considerations
40
41The TNS/E platform is build using the same set of builds specifying `nse`
42instead of `nsx` in the set above.
43
44You cannot build for TNS/E for FIPS, so you must specify the `no-fips`
45option to `./Configure`.
46
47Linking and Loading Considerations
48----------------------------------
49
50Because of how the NonStop Common Runtime Environment (CRE) works, there are
51restrictions on how programs can link and load with OpenSSL libraries.
52On current NonStop platforms, programs cannot both statically link OpenSSL
53libraries and dynamically load OpenSSL shared libraries concurrently. If this
54is done, there is a high probability of encountering a SIGSEGV condition
55relating to `atexit()` processing when a shared library is unloaded and when
56the program terminates. This limitation applies to all OpenSSL shared library
57components.
58
59It is possible to configure the build with `no-atexit` to avoid the SIGSEGV.
60Preferably, you can explicitly call `OPENSSL_cleanup()` from your application.
61It is not mandatory as it just deallocates various global data structures
62OpenSSL allocated.
63
64About Prefix and OpenSSLDir
65---------------------------
66
67Because there are many potential builds that must co-exist on any given
68NonStop node, managing the location of your build distribution is crucial.
69Keep each destination separate and distinct. Mixing any mode described in
70this document can cause application instability. The recommended approach
71is to specify the OpenSSL version and threading model in your configuration
72options, and keeping your memory and float options consistent, for example:
73
74 * For 1.1 `--prefix=/usr/local-ssl1.1 --openssldir=/usr/local-ssl1.1/ssl`
75 * For 1.1 PUT `--prefix=/usr/local-ssl1.1_put --openssldir=/usr/local-ssl1.1_put/ssl`
76
77As of 3.0, the NonStop configurations use the multilib attribute to distinguish
78between different models:
79
80 * For 3.0 `--prefix=/usr/local-ssl3.0 --openssldir=/usr/local-ssl3.0/ssl`
81
82The PUT model is placed in `${prefix}/lib-put` for 32-bit models and
83`${prefix}/lib64-put` for 64-bit models.
84
85Use the `_RLD_LIB_PATH` environment variable in OSS to select the appropriate
86directory containing `libcrypto.so` and `libssl.so`. In GUARDIAN, use the
87`=_RLD_LIB_PATH` search define to locate the GUARDIAN subvolume where OpenSSL
88is installed.
89
90Float Considerations
91--------------------
92
93OpenSSL is built using IEEE Float mode by default. If you need a different
94IEEE mode, create a new configuration specifying `tfloat-x86-64` (for Tandem
95Float) or `nfloat-x86-64` (for Neutral Float).
96
97Memory Models
98-------------
99
100The current OpenSSL default memory model uses the default platform address
101model. If you need a different address model, you must specify the appropriate
102c99 options for compile (`CFLAGS`) and linkers (`LDFLAGS`).
103
104Cross Compiling on Windows
105--------------------------
106
107To configure and compile OpenSSL, you will need to set up a Cygwin environment.
108The Cygwin tools should include bash, make, and any other normal tools required
109for building programs.
110
111Your `PATH` must include the bin directory for the c99 cross-compiler, as in:
112
113    export PATH=/cygdrive/c/Program\ Files\ \(x86\)/HPE\ NonStop/L16.05/usr/bin:$PATH
114
115This should be set before Configure is run. For the c99 cross-compiler to work
116correctly, you also need the `COMP_ROOT` set, as in:
117
118    export COMP_ROOT="C:\Program Files (x86)\HPE NonStop\L16.05"
119
120`COMP_ROOT` needs to be in Windows form.
121
122`Configure` must specify the `no-makedepend` option otherwise errors will
123result when running the build because the c99 cross-compiler does not support
124the `gcc -MT` option. An example of a `Configure` command to be run from the
125OpenSSL directory is:
126
127    ./Configure nonstop-nsx_64 no-makedepend --with-rand-seed=rdcpu
128
129Do not forget to include any OpenSSL cross-compiling prefix and certificate
130options when creating your libraries.
131
132The OpenSSL test suite will not run on your workstation. In order to verify the
133build, you will need to perform the build and test steps in OSS in your NonStop
134server. You can also build under gcc and run the test suite for Windows but that
135is not equivalent.
136
137**Note:** In the event that you are attempting a FIPS-compliant cross-compile,
138be aware that signatures may not match between builds done under OSS and under
139cross-compiles as the compilers do not necessarily generate identical objects.
140Anything and everything to do with FIPS is outside the scope of this document.
141Refer to the FIPS security policy for more information.
142
143The following build configurations have been successfully attempted at one
144point or another. If you are successful in your cross-compile efforts, please
145update this list:
146
147- nonstop-nsx_64
148- nonstop-nsx_64_put
149
150**Note:** Cross-compile builds for TNS/E have not been attempted, but should
151follow the same considerations as for TNS/X above. SPT builds generally require
152FLOSS, which is not available for workstation builds. As a result, SPT builds
153of OpenSSL cannot be cross-compiled.
154
155Also see the NSDEE discussion below for more historical information.
156
157Cross Compiling with NSDEE
158--------------------------
159
160**Note:** None of these builds have been tested by the platform maintainer and
161are supplied for historical value. Please submit a Pull Request to OpenSSL
162should these need to be adjusted.
163
164If you are attempting to build OpenSSL with NSDEE, you will need to specify
165the following variables. The following set of compiler defines are required:
166
167    # COMP_ROOT must be a full path for the build system (e.g. windows)
168    COMP_ROOT=$(cygpath -w /path/to/comp_root)
169    # CC must be executable by your shell
170    CC=/path/to/c99
171
172### Optional Build Variables
173
174    DBGFLAG="--debug"
175    CIPHENABLES="enable-ssl3 enable-ssl3-method enable-weak-ssl-ciphers enable-rc4"
176
177### Internal Known TNS/X to TNS/E Cross Compile Variables
178
179The following definition is required if you are building on TNS/X for TNS/E
180and have access to a TNS/E machine on your EXPAND network - with an example
181node named `\CS3`:
182
183    SYSTEMLIBS="-L/E/cs3/usr/local/lib"
184
185Version Procedure (VPROC) Considerations
186----------------------------------------
187
188If you require a VPROC entry for platform version identification, use the
189following variables:
190
191### For Itanium
192
193    OPENSSL_VPROC_PREFIX=T0085H06
194
195### For x86
196
197    OPENSSL_VPROC_PREFIX=T0085L01
198
199### Common Definition
200
201    export OPENSSL_VPROC=${OPENSSL_VPROC_PREFIX}_$(
202        . VERSION.dat
203        if [ -n "$PRE_RELEASE_TAG" ]; then
204            PRE_RELEASE_TAG="-$PRE_RELEASE_TAG"
205        fi
206        if [ -n "$BUILD_METADATA" ]; then
207            BUILD_METADATA="+$BUILD_METADATA"
208        fi
209        echo "$MAJOR.$MINOR.$PATCH$PRE_RELEASE_TAG$BUILD_METADATA" |\
210            sed -e 's/[-.+]/_/g'
211        )
212
213Example Configure Targets
214-------------------------
215
216For OSS targets, the main DLL names will be `libssl.so` and `libcrypto.so`.
217For GUARDIAN targets, DLL names will be `ssl` and `crypto`. The following
218assumes that your PWD is set according to your installation standards.
