Macro to initialize st_cipher data structure with name, code (IANA cipher

have the same IANA code for both SSL and TLS standards: numbers 0x0000 to
0x001B. They have different names though. The first 4 letters of the cipher
suite name are the protocol name: "SSL_" or "TLS_", rest of the IANA name is
the same for both SSL and TLS cipher suite name.
The second part of the problem is that macOS/iOS SDKs don't define all TLS
codes but only 12 of them. The SDK defines all SSL codes though, i.e. SSL_NUM
constant is always defined for those 28 ciphers while TLS_NUM is defined only
for 12 of the first 28 ciphers. Those 12 TLS cipher codes match to
corresponding SSL enum value and represent the same cipher suite. Therefore
we'll use the SSL enum value for those cipher suites because it is defined
for all 28 of them.
We make internal data consistent and based on TLS names, i.e. all st_cipher
item names start with the "TLS_" prefix.
Summarizing all the above, those 28 first ciphers are presented in our table
with both TLS and SSL names. Their cipher numbers are assigned based on the
SDK enum value for the SSL cipher, which matches to IANA TLS number.

Cipher suites were marked as weak based on the following:
RC4 encryption - rfc7465, the document contains a list of deprecated ciphers.
Marked in the code below as weak.
RC2 encryption - many mentions, was found vulnerable to a relatively easy
attack https://link.springer.com/chapter/10.1007%2F3-540-69710-1_14
Marked in the code below as weak.
DES and IDEA encryption - rfc5469, has a list of deprecated ciphers.
Marked in the code below as weak.
Anonymous Diffie-Hellman authentication and anonymous elliptic curve
Diffie-Hellman - vulnerable to a man-in-the-middle attack. Deprecated by
RFC 4346 aka TLS 1.1 (section A.5, page 60)
Null bulk encryption suites - not encrypted communication
Export ciphers, i.e. ciphers with restrictions to be used outside the US for
software exported to some countries, they were excluded from TLS 1.1
version. More precisely, they were noted as ciphers which MUST NOT be
negotiated in RFC 4346 aka TLS 1.1 (section A.5, pages 60 and 61).
All of those filters were considered weak because they contain a weak
algorithm like DES, RC2 or RC4, and already considered weak by other
criteria.
3DES - NIST deprecated it and is going to retire it by 2023
https://csrc.nist.gov/News/2017/Update-to-Current-Use-and-Deprecation-of-TDEA
OpenSSL https://www.openssl.org/blog/blog/2016/08/24/sweet32/ also
deprecated those ciphers. Some other libraries also consider it
vulnerable or at least not strong enough.
CBC ciphers are vulnerable with SSL3.0 and TLS1.0:
https://www.cisco.com/c/en/us/support/docs/security/email-security-appliance
/118518-technote-esa-00.html
We don't take care of this issue because it is resolved by later TLS
versions and for us, it requires more complicated checks, we need to
check a protocol version also. Vulnerability doesn't look very critical
and we do not filter out those cipher suites.

If a subjectAltName extension of type dNSName is present, that MUST

the use of the Common Name is existing practice, it is deprecated and

Matching is performed using the matching rules specified by
[RFC2459]. If more than one identity of a given type is present in
the certificate (e.g., more than one dNSName name, a match in any one
of the set is considered acceptable.) Names may contain the wildcard
character * which is considered to match any single domain name
component or component fragment. E.g., *.a.com matches foo.a.com but
not bar.foo.a.com. f*.com matches foo.com but not bar.com.
In some cases, the URI is specified as an IP address rather than a

/* OpenSSL contains code to work around lots of bugs and flaws in various
SSL-implementations. SSL_CTX_set_options() is used to enabled those
work-arounds. The man page for this option states that SSL_OP_ALL enables
all the work-arounds and that "It is usually safe to use SSL_OP_ALL to
enable the bug workaround options if compatibility with somewhat broken
implementations is desired."
The "-no_ticket" option was introduced in OpenSSL 0.9.8j. It's a flag to
disable "rfc4507bis session ticket support". rfc4507bis was later turned
into the proper RFC5077 it seems: https://tools.ietf.org/html/rfc5077
The enabled extension concerns the session management. I wonder how often
libcurl stops a connection and then resumes a TLS session. Also, sending
the session data is some overhead. I suggest that you just use your
proposed patch (which explicitly disables TICKET).
If someone writes an application with libcurl and OpenSSL who wants to
enable the feature, one can do this in the SSL callback.
SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option enabling allowed proper
interoperability with web server Netscape Enterprise Server 2.0.1 which
was released back in 1996.
Due to CVE-2010-4180, option SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG has
become ineffective as of OpenSSL 0.9.8q and 1.0.0c. In order to mitigate
CVE-2010-4180 when using previous OpenSSL versions we no longer enable
this option regardless of OpenSSL version and SSL_OP_ALL definition.
OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability
(https://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit to
SSL_OP_ALL that _disables_ that work-around despite the fact that
SSL_OP_ALL is documented to do "rather harmless" workarounds. In order to
keep the secure work-around, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit
must not be set.

# Google Android makefile for curl and libcurl
#
# This file can be used when building curl using the full Android source
# release or the NDK. Most users do not want or need to do this; please
# instead read the Android section in docs/INSTALL for alternate
# methods.
#
# Place the curl source (including this makefile) into external/curl/ in the
# Android source tree. Then build them with 'make curl' or just 'make libcurl'
# from the Android root. Tested with Android versions 1.5, 2.1-2.3
#
# Note: you must first create a curl_config.h file by running configure in the
# Android environment. The only way I've found to do this is tricky. Perform a
# normal Android build with libcurl in the source tree, providing the target
# "showcommands" to make. The build will eventually fail (because curl_config.h
# doesn't exist yet), but the compiler commands used to build curl will be
# shown. Now, from the external/curl/ directory, run curl's normal configure
# command with flags that match what Android itself uses. This will mean
# putting the compiler directory into the PATH, putting the -I, -isystem and
# -D options into CPPFLAGS, putting the -W, -m, -f, -O and -nostdlib options
# into CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the
# path to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o.
# Remember that the paths must be absolute since you will not be running
# configure from the same directory as the Android make. The normal
# cross-compiler options must also be set. Note that the -c, -o, -MD and
# similar flags must not be set.
#
# To see all the LIBS options, you'll need to do the "showcommands" trick on an
# executable that's already buildable and watch what flags Android uses to link
# it (dhcpcd is a good choice to watch). You'll also want to add -L options to
# LIBS that point to the out/.../obj/lib/ and out/.../obj/system/lib/
# directories so that additional libraries can be found and used by curl.
#
# The end result will be a configure command that looks something like this
# (the environment variable A is set to the Android root path which makes the
# command shorter):
#
# A=`realpath ../..` && \
# PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
# ./configure --host=arm-linux CC=arm-eabi-gcc \
# CPPFLAGS="-I $A/system/core/include ..." \
# CFLAGS="-nostdlib -fno-exceptions -Wno-multichar ..." \
# LIBS="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/lib/gcc/arm-eabi/X\
# /interwork/libgcc.a ..."
#
# Finally, copy the file COPYING to NOTICE so that the curl license gets put
# into the right place (but see the note about this below).

Note: These kits are produced by a hobbyist and are providing any support
or any commitment to supply bug fixes or future releases. This code is
as-is with no warrantees.
The testing of this build of curl was minimal and involved building some of
the sample and test programs, accessing a public HTTPS: website, doing a
form post of some VMS test files, and FTP upload of some text files.
Due to the way that PCSI identifies packages, if you install a package from
one producer and then want to upgrade it from another producer, you will
probably need to uninstall the previous package first.
OpenVMS specific building and kitting instructions are after the standard
curl readme file.
This product may be available for your platform in a PCSI kit. The source kit
contains files for building CURL using GNV or with a DCL procedure.
The GNV based build creates a libcurl share imaged which is supplied in the
PCSI kit.
This version of CURL will return VMS compatible status codes when run from
DCL and Unix compatible exit codes and messages when run with the SHELL
environment variable set.
This port of Curl uses the OpenSSL, Ldap, and Kerberos V5 that are bundled
with OpenVMS or supplied as updates by HP. Ldap and Kerberos are not available
on the VAX platform. See section below for a special note about HP OpenSSL
on Alpha and IA64.
The supplied CURL_STARTUP.COM procedure that is installed in
[VMS$COMMON.SYS$STARTUP] can be put in your VMS startup procedure to install
the GNV$LIBCURL shared image and create logical names GNV$LIBCURL to reference
it. It will create the GNV$CURL_INCLUDE logical name for build procedures
to access the header files.
Normally to use curl from DCL, just create a foreign command as:
curl :== $gnv$gnu:[usr.bin]gnv$curl.exe
If you need to work around having the older HP SSL kit installed, then
for DCL create this command procedure:
$ create/dir gnv$gnu:[vms_bin]/prot=w:re
$ create gnv$gnu:[vms_bin]curl.com
$ curl := $gnv$gnu:[usr.bin]gnv$curl.exe
$ define/user ssl$libcrypto_shr32 gnv$curl_ssl_libcryptoshr32
$ curl "''p1'" "''p2'" "''p3'" "''p4'" "''p5'" "''p6'" "''p7'" "''p8'"
^Z
Then you can use: curl :== @gnv$gnu:[vms_bin]curl.com to run curl.
For the HP SSL work around to work for GNV do the following:
$ create/dir gnv$gnu:[usr.local.bin]/prot=w:re
$ create gnv$gnu:[usr.local.bin]curl.
#! /bin/sh
dcl @gnv\$gnu:[vms_bin]curl.com $*
^Z
Similar work arounds will be needed for any program linked with GNV$LIBCURL
until the HP OpenSSL is upgraded to the current 1.4 version or later.
If you are installing a "daily" build instead of a release build of Curl, some
things have been changed so that it can be installed at the same time as
a production build with out conflicts.
The CURL_DAILY_STARTUP.COM will be supplied instead of CURL_STARTUP.COM.
This file is actually not used with the daily package and is provided as
a preview of what the next CURL_STARTUP.COM will be for the next release.
Do not run it.
The files that are normally installed in [VMS$COMMON.GNV.usr], for the
daily build are installed in [VMS$COMMON.GNV.beta] directory.
To use the daily GNV$LIBCURL image, you will need to define the logical
name GNV$LIBCURL to the image.

Currently building Curl using GNV takes longer than building Curl via DCL.
The GNV procedure actually uses the same configure and makefiles that
Unix builds use.
Building CURL on OpenVMS using GNV requires GNV V2.1-2 or the updated
images that are available via anonymous FTP at encompasserve.org in the gnv
directory. It also requires the GNV Bash 4.2.45 kit as an update from the
same location or from the sourceforge.net GNV project.
The HP C 7.x compiler was used for building the GNV version.
The source kits are provided in backup savesets inside of the PCSI install kit.
Backup save sets are currently the only distribution medium that I can be
sure is installed on a target VMS system that will correctly unpack files
with extended character sets in them. You may need to adjust the ownership
of the restored files, since /Interchange/noconvert was not available at the
time that this document was written.
[gnv.common_src]curl_*_original_src.bck is the original source of the curl kit
as provided by the curl project. [gnv.vms_src]curl-*_vms_src.bck, if present,
has the OpenVMS specific files that are used for building that are not yet in
the curl source kits for that release distributed https://curl.se
These backup savesets should be restored to different directory trees on
an ODS-5 volume(s) which are referenced by concealed rooted logical names.
SRC_ROOT: is for the source files common to all platforms.
VMS_ROOT: is for the source files that are specific to OpenVMS.
Note, you should create the VMS_ROOT: directory tree even if it is
initially empty. This is where you should put edits if you are
making changes.
LCL_ROOT: is manually created to have the same base and sub-directories as
SRC_ROOT: and VMS_ROOT:
The logical name REF_ROOT: may be defined to be a search list for
VMS_ROOT:,SRC_ROOT:
The logical name PRJ_ROOT: is defined to be a search list for
LCL_ROOT:,VMS_ROOT:,SRC_ROOT:
For the make install process to work, it must have write access to the
directories referenced by the GNU: logical name.
In future releases of GNV, and with GNV Bash 4.3.30 installed, this name
should be GNV$GNU:
As directly updating those directories would probably be disruptive to other
users of the system and require elevated privilege, this can be handled by
creating a separate directory tree to install into which can be referenced
by the concealed rooted logical name new_gnu:. A concealed logical name of
OLD_GNU: can be set up to reference the real GNV directory tree.
Then a local copy of the GNU/GNV$GNU logical names can be set up as a search
list such as NEW_GNU:,OLD_GNU:
The directory NEW_GNU:[usr] should be created. The make install phase should
create all the other directories.
The make install process may abort if curl is already because it can not
uninstall the older version of curl because it does not have permission.
The file stage_curl_install.com is used set up a new_gnu: directory tree
for testing. The PCSI kitting procedure uses these files as input.
These files do not create the directories in the VMS_ROOT and LCL_ROOT
directory trees. You can create them with commands similar to:
$ create/dir lcl_root:[curl]/prot=w:re
$ copy src_root:[curl...]*.dir -
lcl_root:[curl...]/prot=(o:rwed,w:re)
$ create/dir vms_root:[curl]/prot=w:re
$ copy src_root:[curl...]*.dir -
vms_root:[curl...]/prot=(o:rwed,w:re)
One of the ways with to protect the source from being modified is to have
the directories under src_root: owned by a user or resource where the build
username only has read access to it.
Note to builders:
GNV currently has a bug where configure scripts take a long time to run.
Some of the configure steps take a while to complete, and on a 600 Mhz
DS10 with IDE disks, taking an hour to run the CURL configure is normal.
The following messages can be ignored and may get fixed in a future version
of GNV. The GNV$*.OPT files are used to find the libraries as many have
different names on VMS than on Unix. The Bash environment variable
GNV_CC_QUALIFIERS can override all other settings for the C Compiler.
? cc: No support for switch -warnprotos
? cc: Unrecognized file toomanyargs
? cc: Warning: library "ssl" not found
? cc: Warning: library "crypto" not found
? cc: Warning: library "gssapi" not found
? cc: Warning: library "z" not found
u unimplemented switch - ignored
With these search lists set up and the properly, curl can be built by
setting your default to PRJ_ROOT:[curl.packages.vms] and then issuing
either the command:
$ @pcsi_product_gnv_curl.com
or
$ @build_gnv_curl.com.
The GNV configure procedure takes considerably longer than the DCL build
procedure takes. It is of use for testing the GNV build environment, and
may not have been kept up to date.
The pcsi_product_gnv_curl.com needs the following logical names which
are described in the section below:
gnv_pcsi_producer
gnv_pcsi_producer_full_name
stage_root
vms_root1 (Optional if vms_root is on a NFS volume)
src_root1 (Optional if src_root is on a NFS volume)
The pcsi_product_gnv_curl.com is described in more detail below. It does
the following steps. The build steps are only done if they are needed to
allow using either DCL or GNV based building procedures.
$ @build_vms list
$ @gnv_link_curl.com
$ @build_gnv_curl_release_notes.com
$ @backup_gnv_curl_src.com
$ @build_gnv_curl_pcsi_desc.com
$ @build_gnv_curl_pcsi_text.com
$ @stage_curl_install remove
$ @stage_curl_install
Then builds the kit.
The build_gnv_curl.com command procedure does the following:
$ @setup_gnv_curl_build.com
$ bash gnv_curl_configure.sh
$ @clean_gnv_curl.com
$ bash make_gnv_curl_install.sh
$ @gnv_link_curl.com
$ @stage_curl_install.com
$ purge new_gnu:[*...]/log
To clean up after a GNV based build to start over, the following commands are
used:
$ bash
bash$ cd ../..
bash$ make clean
bash$ exit
Then run the @clean_gnv_curl.com. Use the parameter "realclean" if you are
going to run the setup_gnv_curl_build.com and configure script again.
$ @clean_gnv_curl.com realclean
If new public symbols have been added, adjust the file gnv_libcurl_symbols.opt
to have the new symbols. If the symbols are longer than 32 characters,
then they will need to have the original be exact case CRC shortened and
an alias in upper case with CRC shortened, in addition to having an exact
case truncated alias and an uppercase truncated alias.
The *.EXE files are not moved to the new_gnu: directory.
After you are satisfied with the results of your build, you can move the
files from new_gnu: to old_gnu: at your convenience.
Building a PCSI kit for an architecture takes the following steps after
making sure that you have a working build environment.
Note that it requires manually creating two logical names as described
below. It is intentional that they be manually set. This is for
branding the PCSI kit based on who is making the kit.
1. Make sure that you have a staging directory that can be referenced
by the path STAGE_ROOT:[KIT]
2. Edit the file curl_release_note_start.txt or other text files to
reflect any changes.
3. Define the logical name GNV_PCSI_PRODUCER to indicate who is making
the distribution. For making updates to an existing open source
kit you may need to keep the producer the same.
4. Define the logical name GNV_PCSI_PRODUCER_FULL_NAME to be your full
name or full name of your company.
5. If you are producing an update kit, then update the file
vms_eco_level.h by changing the value for the VMS_ECO_LEVEL macro.
This file is currently only used in building the PCSI kit.
6. Edit the file PCSI_GNV_CURL_FILE_LIST.TXT if there are new files added
to the kit. These files should all be ODS-2 legal filenames and
directories.
A limitation of the PCSI kitting procedure is that when selecting files,
it tends to ignore the directory structure and assumes that all files
with the same name are the same file, so every file placed in the kit
must have a unique name. Then a procedure needs to be added to the kit
to create an alias link on install and remove the link on remove.
Since at this time curl does not need this alias procedure, the steps
to automatically build it are not included here.
While newer versions of PCSI can support ODS-5 filenames, not all versions
of PCSI on systems that have ODS-5 filenames do. So as a post install
step, the PCSI kit built by these steps does a rename to the correct
case as a post install step.
7. Edit the build_curl_pcsi_desc.com and build_curl_pcsi_text.com if you
have changed the version of ZLIB that curl is built against.
8. Prepare to backup the files for building the kit.
Note that if src_root: or vms_root: are NFS mounted disks, the
step of backing up the source files will probably hang or fail.
You need to copy the source files to VMS mounted disks and create
logical names SRC_ROOT1 and VMS_ROOT1 to work around this to to
reference local disks. Make sure src_root1:[000000] and
vms_root1:[000000] exist and can be written to.
The command procedure compare_curl_source can be used to check
those directories and keep them up to date.
@compare_curl_source.com SRCBCK UPDATE
This compares the reference project source with the backup
staging directory for it and updates with any changes.
@compare_curl_source.com VMSBCK UPDATE
This compares the VMS specific source with the backup
staging directory for it and updates with any changes.
Leave off "UPDATE" to just check without doing any changes.
If you are not using NFS mounted disks and do not want to have a
separate directory for staging the sources for backup make sure
that src_root1: and vms_root1: do not exist.
9. Build the PCSI kit with @pcsi_product_gnv_curl.com
The following message is normal:
%PCSI-I-CANNOTVAL, cannot validate
EAGLE$DQA0:[stage_root.][kit]VMSPORTS-AXPVMS-CURL-V0731-0-1.PCSI;1
-PCSI-I-NOTSIGNED, product kit is not signed and therefore has
no manifest file
This will result in an uncompressed kit for the target platform.
On Alpha and Integrity, the pcsi_product_gnv_curl.com can be used with
the "COMPRESSED" parameter to build both a compressed and uncompressed
kits.
Good Luck.
