libreSSL/ChangeLog

Because this project is maintained both in the OpenBSD tree using CVS and in
Git, it can be confusing following all of the changes.

Most of the libssl and libcrypto source code is is here in OpenBSD CVS:

	http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libssl/

Some of the libcrypto and OS-compatibility files for entropy and random number
generation are here:

	http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libcrypto/

A simplified TLS wrapper library is here:

	http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libtls/

The LibreSSL Portable project copies these portions of the OpenBSD tree, along
with relevant portions of the C library, to a Git repository. This makes it
easier to follow all of the relevant changes to the upstream project in a
single place:

	https://github.com/libressl-portable/openbsd

The portable bits of the project are largely maintained out-of-tree, and their
history is also available from Git.

LibreSSL Portable Release Notes:

2.1.4 - Security and feature updates
	* Improvements to libtls:
	  - a new API for loading CA chains directly from memory instead of a
	    file, allowing verification with privilege separation in a chroot
	    without direct access to CA certificate files.

	  - Ciphers default to TLSv1.2 with AEAD and PFS.

	  - Improved error handling and message generation

	  - New APIs and improved documentation

	* Added X509_STORE_load_mem API for loading certificates from memory.
	  This facilitates accessing certificates from a chrooted environment.

	* New AEAD "MAC alias" allows configuring TLSv1.2 AEAD ciphers by
	  using 'TLSv1.2+AEAD' as the cipher selection string.

	* Dead and disabled code removal including MD5, Netscape workarounds,
	  non-POSIX IO, SCTP, RFC 3779 support, many #if 0 sections, and more.

	* ASN1 macro maze expanded to aid reading and searching the code.

	* NULL pointer asserts removed in favor of letting the OS/signal
	  handler catch them.

	* Refactored argument handling in openssl(1) for consistency and
	  maintainability.

	* New openssl(1) command 'certhash' replaces the c_rehash script.

	* Support for building with OPENSSL_NO_DEPRECATED

	* Server-side support for TLS_FALLBACK_SCSV for compatibility with
	  various auditor and vulnerability scanners.

	* Dozens of issues found with the Coverity scanner fixed.

	* Security Updates:

	  - Fix a minor information leak that was introduced in t1_lib.c
	    r1.71, whereby an additional 28 bytes of .rodata (or .data) is
	    provided to the network. In most cases this is a non-issue since
	    the memory content is already public. Issue found and reported by
	    Felix Groebert of the Google Security Team.

	  - Fixes for the following low-severity issues were integrated into
	    LibreSSL from OpenSSL 1.0.1k:

	     CVE-2015-0205 - DH client certificates accepted without
	                     verification
	     CVE-2014-3570 - Bignum squaring may produce incorrect results
	     CVE-2014-8275 - Certificate fingerprints can be modified
	     CVE-2014-3572 - ECDHE silently downgrades to ECDH [Client]
	     Reported by Karthikeyan Bhargavan of the PROSECCO team at INRIA.

	    The following CVEs were fixed in earlier LibreSSL releases:
	     CVE-2015-0206 - Memory leak handling repeated DLTS records
	     CVE-2014-3510 - Flaw handling DTLS anonymous EC(DH) ciphersuites.

	    The following CVEs did not apply to LibreSSL:
	     CVE-2014-3571 - DTLS segmentation fault in dtls1_get_record
	     CVE-2014-3569 - no-ssl3 configuration sets method to NULL
	     CVE-2015-0204 - RSA silently downgrades to EXPORT_RSA

2.1.3 - Security update and OS support improvements
	* Fixed various memory leaks in DTLS, including fixes for
	  CVE-2015-0206.

	* Added Application-Layer Protocol Negotiation (ALPN) support.

	* Removed GOST R 34.10-94 signature authentication.

	* Removed nonfunctional Netscape browser-hang workaround code.

	* Simplfied and refactored SSL/DTLS handshake code.

	* Added SHA256 Camellia cipher suites for TLS 1.2 from RFC 5932.

	* Hide timing info about padding errors during handshakes.

	* Improved libtls support for non-blocking sockets, added randomized
	  session ID contexts. Work is ongoing with this library - feedback
	  and potential use-cases are welcome.

	* Support building Windows DLLs.
	  Thanks to Jan Engelhard.

	* Packaged config wrapper for better compatibility with OpenSSL-based
	  build systems.
	  Thanks to @technion from github

	* Ensure the stack is marked non-executable for assembly sections.
	  Thanks to Anthony G. Bastile.

	* Enable extra compiler hardening flags by default, where applicable.
	  The default set of hardening features can vary by OS to OS, so
	  feedback is welcome on this. To disable the default hardening flags,
	  specify '--disable-hardening' during configure.
	  Thanks to Jim Barlow

	* Initial HP-UX support, tested with HP-UX 11.31 ia64
	  Thanks to Kinichiro Inoguchi

	* Initial NetBSD support, tested with NetBSD 6.1.5 x86_64
	  Imported from OpenNTPD, thanks to @gitisihara from github

2.1.2 - Many new features and improvements
	* Added reworked GOST cipher suite support
	   thanks to Dmitry Eremin-Solenikov

	* Enabled Camellia ciphers due to improved patent situation

	* Use builtin arc4random implementation on OS X and FreeBSD
	   this addresses some deficiencies in the native implementations of
	   these operating systems, see commit logs for more information

	* Added initial Windows mingw-w64 support (32 and 64-bit)
	   thanks to Song Dongsheng and others for code and feedback

	* Enabled assembly optimizations on x86_64 CPUs
	   supports Linux, *BSD, Solaris and OS X operating systems
	   thanks to Wouter Clarie for the initial implementation

	* Added no_ssl3/no_tls1_1/no_tls1_2 options to openssl(1)

	* Improved build infrastructure, 'make distcheck' now passes
	   this simplifies and speeds developer efficiency
	   thanks to Dmitry Eremin-Solenikov and Wouter Clarie

	* Allow conditional building of the libtls library
	   expect the API and ABI of the library to change
	   feedback is welcome

	* Fixes for more memory leaks, cleanups, etc.

2.1.1 - Security update
	* Address POODLE attack by disabling SSLv3 by default

	* Fix Eliptical Curve cipher selection bug

	* The TLS padding extension (that works around bugs in F5 terminators) is
	  off by default

	* support for getrandom(2) on Linux 3.17

	* the NO_ASM macro is no longer being set, providing the first bits toward
	  enabling other assembly offloads.
