Release Notes

libressl/portable (libressl/portable)

v4.0.0

Compare Source

Portable changes

• Added initial Emscripten support in CMake builds.
• Removed timegm() compatibility layer since all uses were replaced
  with OPENSSL_timegm(). Cleaned up the corresponding test harness.
• The mips32 platform is no longer actively supported.
• Fixed Windows support for dates beyond 2038.

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.
• Improved X.509v3 extension internals. Fixed various bugs and leaks
  in X509V3_add1_i2d() and X509V3_get_d2i(). Their implementations
  now vaguely resemble code.
• Rewrote BN_bn2mpi() using CBB.
• Made most error string tables const.
• Removed handling for SSLv2 client hello messages.
• Improvements in the openssl(1) speed app's signal handler.
• Cleaned up various X509v3_* extension API.
• Unified the X.509v3 extension methods.
• Cleaned up cipher handling in SSL_SESSION.
• Removed get_cipher from SSL_METHOD.
• Rewrote CRYPTO_EX_DATA from scratch. The only intentional change of
  behavior is that there is now a hard limit on the number of indexes
  that can be allocated.
• Removed bogus connect() call from netcat.
• Uses of atoi() and strtol() in libcrypto were replaced with
  strtonum().
• Introduced crypto_arch.h which will contain the architecture
  dependent code and defines rather than the public opensslconf.h.
• OPENSSL_cpu_caps() is now architecture independent.
• Reorganized the DES implementation to use fewer files and removed
  optimizations for ancient processors and compilers.

New features

• Added CRLfile option to the cms command of openssl(1) to specify
  additional CRLs for use during verification.

Documentation improvements

• Removed documentation of no longer existing API.
• Unified the description of the obsolete ENGINE parameter that
  needs to remain in many functions and should always be NULL.

Testing and proactive security

• Switched the remaining tests to new certs.

Compatibility changes

• Protocol parsing in libtls was changed. The unsupported TLSv1.1
  and TLSv1.0 protocols are ignored and no longer enable or disable
  TLSv1.2 in surprising ways.
• The dangerous EVP_PKEY*_check(3) family of functions was removed.
  The openssl(1) pkey and pkeyparam commands no longer support the
  -check and -pubcheck flags.
• 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.
• Support for Whirlpool was removed. Applications still using this
  should honor OPENSSL_NO_WHIRLPOOL.
• 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 single prototype to one file.
• Removed conf_api.h and the public API therein.
• Removed ssl2.h, ssl23.h and ui_compat.h.
• Numerous conf and attribute functions were removed. Some unused
  types were removed, others were made opaque.
• Removed the deprecated HMAC_Init() function.
• Removed OPENSSL_load_builtin_modules().
• Removed X509_REQ_{get,set}_extension_nids().
• X509_check_trust() and was removed, X509_VAL was made opaque.
• Only specified versions can be set on certs, CRLs and CSRs.
• 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_*.
• SPKAC support was removed from openssl(1).
• Added TLS1-PRF support to the EVP interface.
• Support for attributes in EVP_PKEYs was removed.
• The X509at_* API is no longer public.
• SSL_CTX_set1_cert_store() and SSL_CIPHER_get_handshake_digest()
  were added to libssl.
• The completely broken UI_UTIL password API was removed.
• The OpenSSL pkcs12 command and PKCS12_create() no longer support
  setting the Microsoft-specific Local Key Set and Cryptographic
  Service Provider attributes.

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.
• Implemented RSA key exchange in constant time. This is done by
  decrypting with RSA_NO_PADDING and checking the padding in libssl
  in constant time. This is possible because the pre-master secret
  is of known length based on the size of the RSA key.
• Rewrote SSL_select_next_proto() using CBS, also fixing a buffer
  overread that wasn't reachable when used as intended from an
  ALPN callback.
• Avoid pushing a spurious error onto the error stack in
  ssl_sigalg_select().
• Made fatal alerts fatal in QUIC.
