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:
https://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:
https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libcrypto/
A simplified TLS wrapper library is here:
https://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/openbsd
The portable bits of the project are largely maintained out-of-tree, and their
history is also available from Git.
https://github.com/libressl/portable
LibreSSL Portable Release Notes:
4.0.0 - In development
* Portable changes
- Removed timegm() compatibility layer since all uses were replaced
with OPENSSL_timegm(). Cleaned up the corresponding test harness.
* Internal improvements
- Cleaned up parts of the conf directory. Simplified some logic,
fixed memory leaks.
- Simplified X509_check_trust() internals to be somewhat readable.
- Removed last internal uses of gmtime() and timegm() and replaced
them with BoringSSL's posix time conversion API.
- Removed unnecessary stat calls in by_dir.
- Split parsing and processing of TLS extensions to ensure that
extension callbacks are called in a predefined order.
- Cleaned up the MD4 and MD5 implementations.
- Assembly functions are no longer exposed in the public API, they
are all wrapped by C functions.
- Removed assembly implementations of legacy ciphers on legacy
architectures.
- Merged most multi-file implementations of ciphers into one or two
C files.
- Removed the cache of certificate validity. This was added for
performance reasons which no longer apply since BoringSSL's time
conversion API isn't slow. Also, a recently added error check led
to obscure, undesirable validation failures.
- Stopped calling OPENSSL_cpuid_setup() from the .init section on
amd64 and i386.
- Rewrote various BN conversion functions.
- Improved certification request internals.
- Removed unused DSA methods.
* Documentation improvements
- Removed documentation of no longer existing API.
* Testing and proactive security
- Switched the remaining tests to new certs.
* Compatibility changes
- The one-step hashing functions, MD4(), MD5(), RIPEMD160(), SHA1(),
all SHA-2, and HMAC() no longer support returning a static buffer.
Callers must pass in a correctly sized buffer.
- Removed workaround for F5 middle boxes.
- Removed the useless pem2.h, a public header that was added since
it was too hard to add a prototype to one file.
- Only specified versions can be set on certs, CRLs and CSRs.
- Prepared X509_REQ_{get,set}_extension_nids() for removal.
- Removed unused PEM_USER and PEM_CTX types from pem.h.
- Removed typdefs for COMP_CTX, COMP_METHOD, X509_CRL_METHOD, STORE,
STORE_METHOD, and SSL_AEAD_CTX.
- i2d_ASN1_OBJECT() now returns -1 on error like most other i2d_*.
* Bug fixes
- Made ASN1_TIME_set_string() and ASN1_TIME_set_string_X509() match
their documentation. They always set an RFC 5280 conformant time.
- Improved standards compliance for supported groups and key shares
extensions:
- Duplicate key shares are disallowed.
- Duplicate supported groups are disallowed.
- Key shares must be sent in the order of supported groups.
- Key shares will only be selected if they match the most
preferred supported group by client preference order.
- Fixed signed integer overflow in bnrand().
- Prevent negative zero from being created via BN_clear_bit() and
BN_mask_bits(). Avoids a one byte overread in BN_bn2mpi().
- Add guard to avoid contracting the number linear hash buckets
to zero, which could lead to a crash due to accessing a zero
sized allocation.
- Fixed i2d_ASN1_OBJECT() with an output buffer pointing to NULL.
3.9.0 - Development release
* Portable changes
- libcrypto no longer exports compat symbols in cmake builds.
- Most compatibility symbols are prefixed with libressl_ to avoid
symbol clashes in static links.
- Fixed various warnings on Windows.
- Removed assert pop-ups with Windows debug builds.
- Fixed crashes and hangs in Windows ARM64 builds.
- Improved control-flow enforcement (CET) support.
* Internal improvements
- Converted uses of OBJ_bsearch_() to standard bsearch().
- Greatly simplified by_file_ctrl().
- Simplified and cleaned up the OBJ_ API.
- Cleaned up the EVP_Cipher{Init,Update,Final}() implementations.
- Removed unused function pointers from X.509 stores and contexts.
- A lot of cleanup and reorganization in EVP.
- Removed all remaining ENGINE tentacles.
- Simplified internals of X509_TRUST handling.
- Made deletion from a lhash doall callback safe.
- Rewrote BIO_dump*(3) internals to be less bad.
* Documentation improvements
- ENGINE documentation was updated to reflect reality.
- Made EVP API documentation more accurate and less incoherent.
- Call out some shortcomings of the EC_KEY_set_* API explicitly.
* Testing and proactive security
- Bug fixes and simplifications in the Wycheproof tests.
* Compatibility changes
- Added ChaCha20 and chacha20 aliases for ChaCha.
- SSL_library_init() now has the same effect as OPENSSL_init_ssl().
- EVP_add_{cipher,digest}() were removed. From the OBJ_NAME API,
only OBJ_NAME_do_all*() remain. In particular, it is no longer
possible to add aliases for ciphers and digests.
- The thread unsafe global tables are no longer supported. It is no
longer possible to add aliases for ciphers and digests, custom ASN.1
strings table entries, ASN.1 methods, PKEY methods, digest methods,
CRL methods, purpose and trust identifiers, or X.509 extensions.
- Removed the _cb() and _fp() versions of BIO_dump{,_indent}().
- BIO_set() was removed.
- BIO_{sn,v,vsn}printf() were removed.
- Turn the long dysfunctional openssl(1) s_client -pause into a noop.
- openssl(1) x509 now supports -new -force_pubkey, -multivalue-rdn,
-set_issuer, -set_subject, and -utf8.
- Support ECDSA with SHA-3 signature algorithms.
- Support HMAC with truncated SHA-2 and SHA-3 as PBE PRF.
- GOST and STREEBOG support was removed.
- CRYPTO_THREADID, _LHASH, _STACK, X509_PURPOSE are now opaque,
X509_CERT_AUX and X509_TRUST were removed from the public API.
- ASN1_STRING_TABLE_get() and X509_PURPOSE_get0*() now return const
pointers.
- EVP_{CIPHER,MD}_CTX_init()'s signatures and semantics now match
OpenSSL's behavior.
- sk_find_ex() and OBJ_bsearch_() were removed.
- CRYPTO_malloc() was fixed to use size_t argument. CRYPTO_malloc()
and CRYPTO_free() now accept file and line arguments.
- A lot of decrepit CRYPTO memory API was removed.
* Bug fixes
- Fixed aliasing issues in BN_mod_exp_simple() and BN_mod_exp_recp().
- Fixed numerous misuses of X509_ALGOR_set0() resulting in leaks and
potentially incorrect encodings.
- Fixed potential double free in X509v3_asid_add_id_or_range().
- Stopped using ASN1_time_parse() outside of libcrypto.
- Prepared OPENSSL_gmtime() and OPENSSL_timegm() as public API
wrappers of internal functions compatible with BoringSSL API.
- Removed print_bin() to avoid overwriting the stack with 5 bytes
of ' ' when ECPK parameters are printed with large indentation.
- Avoid a NULL dereference after memory allocation failure during TLS
version downgrade.
- Fixed various bugs in CMAC internals.
- Fixed 4-byte overreads in GHASH assembly on amd64 and i386.

* Portable changes
- Applications bundled as part of the LibreSSL package internally,
nc(1) and openssl(1), now are linked statically if static libraries
are built.

stack or ex_data implementation.
* Bug fixes
- Fixed aliasing issue in BN_mod_inverse().
- Made CRYPTO_get_ex_new_index() not return 0 to allow applications
to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
each other.
- Made EVP_PKEY_set1_hkdf_key() fail on a NULL key.
- Plugged leaks in BIO_chain_dup().

3.5.1 - Security release
* A malicious certificate can cause an infinite loop.
Reported by and fix from Tavis Ormandy and David Benjamin, Google.
3.5.0 - Development release
* New Features
- The RFC 3779 API was ported from OpenSSL. Many bugs were fixed,
regression tests were added and the code was cleaned up.
- Certificate Transparency was ported from OpenSSL. Many internal
improvements were made, resulting in cleaner and safer code.
Regress coverage was added. libssl does not yet make use of it.
* Portable Improvements
- Fixed various POSIX compliance and other portability issues
found by the port to the Sortix operating system.
- Add libmd as platform specific libraries for Solaris.
Issue reported from (ihsan <at> opencsw org) on libressl ML.
- Set IA-64 compiler flag only if it is HP-UX with IA-64.
Suggested from Larkin Nickle (me <at> larbob org) by libressl ML.
- Enabled and scheduled Coverity scan.
Contributed by Ilya Shipitsin (chipitsine <at> gmail com> on github.
* Compatibility Changes
- Most structs that were previously defined in the following headers
are now opaque as they are in OpenSSL 1.1:
bio.h, bn.h, comp.h, dh.h, dsa.h, evp.h, hmac.h, ocsp.h, rsa.h,
x509.h, x509v3.h, x509_vfy.h
- Switch TLSv1.3 cipher names from AEAD- to OpenSSL's TLS_
OpenSSL added the TLSv1.3 ciphersuites with "RFC names" instead
of using something consistent with the previous naming. Various
test suites expect these names (instead of checking for the much
more sensible cipher numbers). The old names are still accepted
as aliases.
- Subject alternative names and name constraints are now validated
when they are added to certificates. Various interoperability
problems with stacks that validate certificates more strictly
than OpenSSL can be avoided this way.
- Attempt to opportunistically use the host name for SNI in s_client
* Bug fixes
- In some situations, the verifier would discard the error on an
unvalidated certificate chain. This would happen when the
verification callback was in use, instructing the verifier to
continue unconditionally. This could lead to incorrect decisions
being made in software.
- Avoid an infinite loop in SSL_shutdown()
