Changes between 1.1.0g and 1.1.0h [27 Mar 2018]
Changes between 1.1.0g and 1.1.1 [xx XXX xxxx]
*) Constructed ASN.1 types with a recursive definition could exceed the stack
*) Extend OSSL_STORE with capabilities to search and to narrow the set of
objects loaded. This adds the functions OSSL_STORE_expect() and
OSSL_STORE_find() as well as needed tools to construct searches and
get the search data out of them.
[Richard Levitte]
Constructed ASN.1 types with a recursive definition (such as can be found
in PKCS7) could eventually exceed the stack given malicious input with
excessive recursion. This could result in a Denial Of Service attack. There
are no such structures used within SSL/TLS that come from untrusted sources
so this is considered safe.
*) Support for TLSv1.3 added. Note that users upgrading from an earlier
version of OpenSSL should review their configuration settings to ensure
that they are still appropriate for TLSv1.3. In particular if no TLSv1.3
ciphersuites are enabled then OpenSSL will refuse to make a connection
unless (1) TLSv1.3 is explicitly disabled or (2) the ciphersuite
configuration is updated to include suitable ciphersuites. The DEFAULT
ciphersuite configuration does include TLSv1.3 ciphersuites. For further
information on this and other related issues please see:
https://www.openssl.org/blog/blog/2018/02/08/tlsv1.3/
This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz
project.
(CVE-2018-0739)
NOTE: In this pre-release of OpenSSL a draft version of the
TLSv1.3 standard has been implemented. Implementations of different draft
versions of the standard do not inter-operate, and this version will not
inter-operate with an implementation of the final standard when it is
eventually published. Different pre-release versions may implement
different versions of the draft. The final version of OpenSSL 1.1.1 will
implement the final version of the standard.
TODO(TLS1.3): Remove the above note before final release
[Matt Caswell]
*) Incorrect CRYPTO_memcmp on HP-UX PA-RISC
*) Grand redesign of the OpenSSL random generator
Because of an implementation bug the PA-RISC CRYPTO_memcmp function is
effectively reduced to only comparing the least significant bit of each
byte. This allows an attacker to forge messages that would be considered as
authenticated in an amount of tries lower than that guaranteed by the
security claims of the scheme. The module can only be compiled by the
HP-UX assembler, so that only HP-UX PA-RISC targets are affected.
The default RAND method now utilizes an AES-CTR DRBG according to
NIST standard SP 800-90Ar1. The new random generator is essentially
a port of the default random generator from the OpenSSL FIPS 2.0
object module. It is a hybrid deterministic random bit generator
using an AES-CTR bit stream and which seeds and reseeds itself
automatically using trusted system entropy sources.
This issue was reported to OpenSSL on 2nd March 2018 by Peter Waltenberg
(IBM).
(CVE-2018-0733)
Some of its new features are:
o Support for multiple DRBG instances with seed chaining.
o Add a public DRBG instance for the default RAND method.
o Add a dedicated DRBG instance for generating long term private keys.
o Make the DRBG instances fork-safe.
o Keep all global DRBG instances on the secure heap if it is enabled.
o Add a DRBG instance to every SSL instance for lock free operation
and to increase unpredictability.

*) Changed Configure so it only says what it does and doesn't dump
so much data. Instead, ./configdata.pm should be used as a script
to display all sorts of configuration data.
[Richard Levitte]
*) Added processing of "make variables" to Configure.
[Richard Levitte]
*) Added SHA512/224 and SHA512/256 algorithm support.
[Paul Dale]
*) The last traces of Netware support, first removed in 1.1.0, have
now been removed.
[Rich Salz]
*) Get rid of Makefile.shared, and in the process, make the processing
of certain files (rc.obj, or the .def/.map/.opt files produced from
the ordinal files) more visible and hopefully easier to trace and
debug (or make silent).
[Richard Levitte]
*) Make it possible to have environment variable assignments as
arguments to config / Configure.
[Richard Levitte]
*) Add multi-prime RSA (RFC 8017) support.
[Paul Yang]
*) Add SM3 implemented according to GB/T 32905-2016
[ Jack Lloyd <jack.lloyd@ribose.com>,
Ronald Tse <ronald.tse@ribose.com>,
Erick Borsboom <erick.borsboom@ribose.com> ]

as documented in RFC6066.

*) Reimplement -newreq-nodes and ERR_error_string_n; the
original author does not agree with the license change.
[Rich Salz]
*) Add ARIA AEAD TLS support.
[Jon Spillett]
*) Some macro definitions to support VS6 have been removed. Visual
Studio 6 has not worked since 1.1.0
[Rich Salz]
*) Add ERR_clear_last_mark(), to allow callers to clear the last mark
without clearing the errors.
[Richard Levitte]
*) Add "atfork" functions. If building on a system that without
pthreads, see doc/man3/OPENSSL_fork_prepare.pod for application
requirements. The RAND facility now uses/requires this.
[Rich Salz]
*) Add SHA3.
[Andy Polyakov]
*) The UI API becomes a permanent and integral part of libcrypto, i.e.
not possible to disable entirely. However, it's still possible to
disable the console reading UI method, UI_OpenSSL() (use UI_null()
as a fallback).
To disable, configure with 'no-ui-console'. 'no-ui' is still
possible to use as an alias. Check at compile time with the
macro OPENSSL_NO_UI_CONSOLE. The macro OPENSSL_NO_UI is still
possible to check and is an alias for OPENSSL_NO_UI_CONSOLE.
[Richard Levitte]
*) Add a STORE module, which implements a uniform and URI based reader of
stores that can contain keys, certificates, CRLs and numerous other
objects. The main API is loosely based on a few stdio functions,
and includes OSSL_STORE_open, OSSL_STORE_load, OSSL_STORE_eof,
OSSL_STORE_error and OSSL_STORE_close.
The implementation uses backends called "loaders" to implement arbitrary
URI schemes. There is one built in "loader" for the 'file' scheme.
[Richard Levitte]
*) Add devcrypto engine. This has been implemented against cryptodev-linux,
then adjusted to work on FreeBSD 8.4 as well.
Enable by configuring with 'enable-devcryptoeng'. This is done by default
on BSD implementations, as cryptodev.h is assumed to exist on all of them.
[Richard Levitte]
*) Module names can prefixed with OSSL_ or OPENSSL_. This affects
util/mkerr.pl, which is adapted to allow those prefixes, leading to
error code calls like this:
OSSL_FOOerr(OSSL_FOO_F_SOMETHING, OSSL_FOO_R_WHATEVER);
With this change, we claim the namespaces OSSL and OPENSSL in a manner
that can be encoded in C. For the foreseeable future, this will only
affect new modules.
[Richard Levitte and Tim Hudson]
*) Removed BSD cryptodev engine.
[Rich Salz]
*) Add a build target 'build_all_generated', to build all generated files
and only that. This can be used to prepare everything that requires
things like perl for a system that lacks perl and then move everything
to that system and do the rest of the build there.
[Richard Levitte]
*) Backport SSL_OP_NO_RENGOTIATION
*) In the UI interface, make it possible to duplicate the user data. This
can be used by engines that need to retain the data for a longer time
than just the call where this user data is passed.
[Richard Levitte]
OpenSSL 1.0.2 and below had the ability to disable renegotiation using the
(undocumented) SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS flag. Due to the opacity
changes this is no longer possible in 1.1.0. Therefore the new
SSL_OP_NO_RENEGOTIATION option from 1.1.1-dev has been backported to
1.1.0 to provide equivalent functionality.
*) Ignore the '-named_curve auto' value for compatibility of applications
with OpenSSL 1.0.2.
[Tomas Mraz <tmraz@fedoraproject.org>]
Note that if an application built against 1.1.0h headers (or above) is run
using an older version of 1.1.0 (prior to 1.1.0h) then the option will be
accepted but nothing will happen, i.e. renegotiation will not be prevented.
*) Fragmented SSL/TLS alerts are no longer accepted. An alert message is 2
bytes long. In theory it is permissible in SSLv3 - TLSv1.2 to fragment such
alerts across multiple records (some of which could be empty). In practice
it make no sense to send an empty alert record, or to fragment one. TLSv1.3
prohibts this altogether and other libraries (BoringSSL, NSS) do not
support this at all. Supporting it adds significant complexity to the
record layer, and its removal is unlikely to cause inter-operability
issues.
[Matt Caswell]
*) Add the ASN.1 types INT32, UINT32, INT64, UINT64 and variants prefixed
with Z. These are meant to replace LONG and ZLONG and to be size safe.
The use of LONG and ZLONG is discouraged and scheduled for deprecation
in OpenSSL 1.2.0.
[Richard Levitte]
*) Add the 'z' and 'j' modifiers to BIO_printf() et al formatting string,
'z' is to be used for [s]size_t, and 'j' - with [u]int64_t.
[Richard Levitte, Andy Polyakov]
*) Add EC_KEY_get0_engine(), which does for EC_KEY what RSA_get0_engine()
does for RSA, etc.
[Richard Levitte]
*) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target
platform rather than 'mingw'.
[Richard Levitte]
*) The functions X509_STORE_add_cert and X509_STORE_add_crl return
success if they are asked to add an object which already exists
in the store. This change cascades to other functions which load
certificates and CRLs.
[Paul Dale]
*) x86_64 assembly pack: annotate code with DWARF CFI directives to
facilitate stack unwinding even from assembly subroutines.
[Andy Polyakov]
*) Remove VAX C specific definitions of OPENSSL_EXPORT, OPENSSL_EXTERN.
Also remove OPENSSL_GLOBAL entirely, as it became a no-op.
[Richard Levitte]
*) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c.
VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1,
which is the minimum version we support.
[Richard Levitte]
*) Certificate time validation (X509_cmp_time) enforces stricter
compliance with RFC 5280. Fractional seconds and timezone offsets
are no longer allowed.
[Emilia Käsper]
*) Add support for ARIA
[Paul Dale]
*) s_client will now send the Server Name Indication (SNI) extension by
default unless the new "-noservername" option is used. The server name is
based on the host provided to the "-connect" option unless overridden by
using "-servername".
[Matt Caswell]
*) Add support for SipHash
[Todd Short]
*) OpenSSL now fails if it receives an unrecognised record type in TLS1.0
or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to
prevent issues where no progress is being made and the peer continually
sends unrecognised record types, using up resources processing them.
[Matt Caswell]
*) 'openssl passwd' can now produce SHA256 and SHA512 based output,
using the algorithm defined in
https://www.akkadia.org/drepper/SHA-crypt.txt

OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
OPENSSL_IMPLEMENT_GLOBAL(double,bar);
OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
OPENSSL_IMPLEMENT_GLOBAL(double,bar);
To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
OPENSSL_DECLARE_GLOBAL(int,foo);
#define foo OPENSSL_GLOBAL_REF(foo)
OPENSSL_DECLARE_GLOBAL(double,bar);
#define bar OPENSSL_GLOBAL_REF(bar)
OPENSSL_DECLARE_GLOBAL(int,foo);
#define foo OPENSSL_GLOBAL_REF(foo)
OPENSSL_DECLARE_GLOBAL(double,bar);
#define bar OPENSSL_GLOBAL_REF(bar)
The #defines are very important, and therefore so is including the
header file everywhere where the defined globals are used.
