return an error
[Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
- *) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites
- from RFC4279, RFC4785, RFC5487, RFC5489.
-
- Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the
- original RSA_PSK patch.
- [Steve Henson]
-
- *) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay
- era flag was never set throughout the codebase (only read). Also removed
- SSL3_FLAGS_POP_BUFFER which was only used if
- SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set.
- [Matt Caswell]
-
- *) Changed the default name options in the "ca", "crl", "req" and "x509"
- to be "oneline" instead of "compat".
- [Richard Levitte]
-
- *) Remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is SSLeay legacy, we're
- not aware of clients that still exhibit this bug, and the workaround
- hasn't been working properly for a while.
- [Emilia Käsper]
-
- *) The return type of BIO_number_read() and BIO_number_written() as well as
- the corresponding num_read and num_write members in the BIO structure has
- changed from unsigned long to uint64_t. On platforms where an unsigned
- long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is
- transferred.
- [Matt Caswell]
-
- *) Given the pervasive nature of TLS extensions it is inadvisable to run
- OpenSSL without support for them. It also means that maintaining
- the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
- not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed.
- [Matt Caswell]
-
- *) Removed support for the two export grade static DH ciphersuites
- EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
- were newly added (along with a number of other static DH ciphersuites) to
- 1.0.2. However the two export ones have *never* worked since they were
- introduced. It seems strange in any case to be adding new export
- ciphersuites, and given "logjam" it also does not seem correct to fix them.
- [Matt Caswell]
-
- *) Version negotiation has been rewritten. In particular SSLv23_method(),
- SSLv23_client_method() and SSLv23_server_method() have been deprecated,
- and turned into macros which simply call the new preferred function names
- TLS_method(), TLS_client_method() and TLS_server_method(). All new code
- should use the new names instead. Also as part of this change the ssl23.h
- header file has been removed.
- [Matt Caswell]
-
- *) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This
- code and the associated standard is no longer considered fit-for-purpose.
- [Matt Caswell]
-
- *) RT2547 was closed. When generating a private key, try to make the
- output file readable only by the owner. This behavior change might
- be noticeable when interacting with other software.
-
- *) Added HTTP GET support to the ocsp command.
- [Rich Salz]
-
- *) RAND_pseudo_bytes has been deprecated. Users should use RAND_bytes instead.
- [Matt Caswell]
-
- *) Added support for TLS extended master secret from
- draft-ietf-tls-session-hash-03.txt. Thanks for Alfredo Pironti for an
- initial patch which was a great help during development.
- [Steve Henson]
-
- *) All libssl internal structures have been removed from the public header
- files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is
- now redundant). Users should not attempt to access internal structures
- directly. Instead they should use the provided API functions.
- [Matt Caswell]
-
- *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.
- Access to deprecated functions can be re-enabled by running config with
- "enable-deprecated". In addition applications wishing to use deprecated
- functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
- will, by default, disable some transitive includes that previously existed
- in the header files (e.g. ec.h will no longer, by default, include bn.h)
- [Matt Caswell]
-
- *) Added support for OCB mode. OpenSSL has been granted a patent license
- compatible with the OpenSSL license for use of OCB. Details are available
- at https://www.openssl.org/docs/misc/OCB-patent-grant-OpenSSL.pdf. Support
- for OCB can be removed by calling config with no-ocb.
- [Matt Caswell]
-
- *) SSLv2 support has been removed. It still supports receiving a SSLv2
- compatible client hello.
- [Kurt Roeckx]
-
- *) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz],
- done while fixing the error code for the key-too-small case.
- [Annie Yousar <a.yousar@informatik.hu-berlin.de>]
-
- *) CA.sh has been removmed; use CA.pl instead.
- [Rich Salz]
-
- *) Removed old DES API.
- [Rich Salz]
-
- *) Remove various unsupported platforms:
- Sony NEWS4
- BEOS and BEOS_R5
- NeXT
- SUNOS
- MPE/iX
- Sinix/ReliantUNIX RM400
- DGUX
- NCR
- Tandem
- Cray
- 16-bit platforms such as WIN16
- [Rich Salz]
-
- *) Clean up OPENSSL_NO_xxx #define's
- Use setbuf() and remove OPENSSL_NO_SETVBUF_IONBF
- Rename OPENSSL_SYSNAME_xxx to OPENSSL_SYS_xxx
- OPENSSL_NO_EC{DH,DSA} merged into OPENSSL_NO_EC
- OPENSSL_NO_RIPEMD160, OPENSSL_NO_RIPEMD merged into OPENSSL_NO_RMD160
- OPENSSL_NO_FP_API merged into OPENSSL_NO_STDIO
- Remove OPENSSL_NO_BIO OPENSSL_NO_BUFFER OPENSSL_NO_CHAIN_VERIFY
- OPENSSL_NO_EVP OPENSSL_NO_FIPS_ERR OPENSSL_NO_HASH_COMP
- OPENSSL_NO_LHASH OPENSSL_NO_OBJECT OPENSSL_NO_SPEED OPENSSL_NO_STACK
- OPENSSL_NO_X509 OPENSSL_NO_X509_VERIFY
- Remove MS_STATIC; it's a relic from platforms <32 bits.
- [Rich Salz]
-
- *) Cleaned up dead code
- Remove all but one '#ifdef undef' which is to be looked at.
- [Rich Salz]
-
- *) Clean up calling of xxx_free routines.
- Just like free(), fix most of the xxx_free routines to accept
- NULL. Remove the non-null checks from callers. Save much code.
- [Rich Salz]
-
- *) Add secure heap for storage of private keys (when possible).
- Add BIO_s_secmem(), CBIGNUM, etc.
- Contributed by Akamai Technologies under our Corporate CLA.
- [Rich Salz]
-
- *) Experimental support for a new, fast, unbiased prime candidate generator,
- bn_probable_prime_dh_coprime(). Not currently used by any prime generator.
- [Felix Laurie von Massenbach <felix@erbridge.co.uk>]
-
- *) New output format NSS in the sess_id command line tool. This allows
- exporting the session id and the master key in NSS keylog format.
- [Martin Kaiser <martin@kaiser.cx>]
-
- *) Harmonize version and its documentation. -f flag is used to display
- compilation flags.
- [mancha <mancha1@zoho.com>]
-
- *) Fix eckey_priv_encode so it immediately returns an error upon a failure
- in i2d_ECPrivateKey. Thanks to Ted Unangst for feedback on this issue.
- [mancha <mancha1@zoho.com>]
-
- *) Fix some double frees. These are not thought to be exploitable.
- [mancha <mancha1@zoho.com>]
-
- *) A missing bounds check in the handling of the TLS heartbeat extension
- can be used to reveal up to 64k of memory to a connected client or
- server.
-
- Thanks for Neel Mehta of Google Security for discovering this bug and to
- Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
- preparing the fix (CVE-2014-0160)
- [Adam Langley, Bodo Moeller]
-
- *) Fix for the attack described in the paper "Recovering OpenSSL
- ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack"
- by Yuval Yarom and Naomi Benger. Details can be obtained from:
- http://eprint.iacr.org/2014/140
-
- Thanks to Yuval Yarom and Naomi Benger for discovering this
- flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
- [Yuval Yarom and Naomi Benger]
-
- *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file():
- this fixes a limitation in previous versions of OpenSSL.
- [Steve Henson]
-
- *) Experimental encrypt-then-mac support.
-
- Experimental support for encrypt then mac from
- draft-gutmann-tls-encrypt-then-mac-02.txt
-
- To enable it set the appropriate extension number (0x42 for the test
- server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42
-
- For non-compliant peers (i.e. just about everything) this should have no
- effect.
-
- WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.
-
- [Steve Henson]
-
- *) Add EVP support for key wrapping algorithms, to avoid problems with
- existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
- the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
- algorithms and include tests cases.
- [Steve Henson]
-
- *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
- enveloped data.
- [Steve Henson]
-
- *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
- MGF1 digest and OAEP label.
- [Steve Henson]
-
- *) Make openssl verify return errors.
- [Chris Palmer <palmer@google.com> and Ben Laurie]
-
- *) New function ASN1_TIME_diff to calculate the difference between two
- ASN1_TIME structures or one structure and the current time.
- [Steve Henson]
-
- *) Update fips_test_suite to support multiple command line options. New
- test to induce all self test errors in sequence and check expected
- failures.
- [Steve Henson]
-
- *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
- sign or verify all in one operation.
- [Steve Henson]
-
- *) Add fips_algvs: a multicall fips utility incorporating all the algorithm
- test programs and fips_test_suite. Includes functionality to parse
- the minimal script output of fipsalgest.pl directly.
- [Steve Henson]
-
- *) Add authorisation parameter to FIPS_module_mode_set().
- [Steve Henson]
-
- *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.
- [Steve Henson]
-
- *) Use separate DRBG fields for internal and external flags. New function
- FIPS_drbg_health_check() to perform on demand health checking. Add
- generation tests to fips_test_suite with reduced health check interval to
- demonstrate periodic health checking. Add "nodh" option to
- fips_test_suite to skip very slow DH test.
- [Steve Henson]
-
- *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
- based on NID.
- [Steve Henson]
-
- *) More extensive health check for DRBG checking many more failure modes.
- New function FIPS_selftest_drbg_all() to handle every possible DRBG
- combination: call this in fips_test_suite.
- [Steve Henson]
-
- *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test
- and POST to handle Dual EC cases.
- [Steve Henson]
-
- *) Add support for canonical generation of DSA parameter 'g'. See
- FIPS 186-3 A.2.3.
-
- *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
- POST to handle HMAC cases.
- [Steve Henson]
-
- *) Add functions FIPS_module_version() and FIPS_module_version_text()
- to return numerical and string versions of the FIPS module number.
- [Steve Henson]
-
- *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
- FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
- outside the validated module in the FIPS capable OpenSSL.
- [Steve Henson]
-
- *) Minor change to DRBG entropy callback semantics. In some cases
- there is no multiple of the block length between min_len and
- max_len. Allow the callback to return more than max_len bytes
- of entropy but discard any extra: it is the callback's responsibility
- to ensure that the extra data discarded does not impact the
- requested amount of entropy.
- [Steve Henson]
-
- *) Add PRNG security strength checks to RSA, DSA and ECDSA using
- information in FIPS186-3, SP800-57 and SP800-131A.
- [Steve Henson]
-
- *) CCM support via EVP. Interface is very similar to GCM case except we
- must supply all data in one chunk (i.e. no update, final) and the
- message length must be supplied if AAD is used. Add algorithm test
- support.
- [Steve Henson]
-
- *) Initial version of POST overhaul. Add POST callback to allow the status
- of POST to be monitored and/or failures induced. Modify fips_test_suite
- to use callback. Always run all selftests even if one fails.
- [Steve Henson]
-
- *) XTS support including algorithm test driver in the fips_gcmtest program.
- Note: this does increase the maximum key length from 32 to 64 bytes but
- there should be no binary compatibility issues as existing applications
- will never use XTS mode.
- [Steve Henson]
-
- *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
- to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
- performs algorithm blocking for unapproved PRNG types. Also do not
- set PRNG type in FIPS_mode_set(): leave this to the application.
- Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
- the standard OpenSSL PRNG: set additional data to a date time vector.
- [Steve Henson]
-
- *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
- This shouldn't present any incompatibility problems because applications
- shouldn't be using these directly and any that are will need to rethink
- anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
- [Steve Henson]
-
- *) Extensive self tests and health checking required by SP800-90 DRBG.
- Remove strength parameter from FIPS_drbg_instantiate and always
- instantiate at maximum supported strength.
- [Steve Henson]
-
- *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
- [Steve Henson]
-
- *) New algorithm test program fips_dhvs to handle DH primitives only testing.
- [Steve Henson]
-
- *) New function DH_compute_key_padded() to compute a DH key and pad with
- leading zeroes if needed: this complies with SP800-56A et al.
- [Steve Henson]
-
- *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
- anything, incomplete, subject to change and largely untested at present.
- [Steve Henson]
-
- *) Modify fipscanisteronly build option to only build the necessary object
- files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
- [Steve Henson]
-
- *) Add experimental option FIPSSYMS to give all symbols in
- fipscanister.o and FIPS or fips prefix. This will avoid
- conflicts with future versions of OpenSSL. Add perl script
- util/fipsas.pl to preprocess assembly language source files
- and rename any affected symbols.
- [Steve Henson]
-
- *) Add selftest checks and algorithm block of non-fips algorithms in
- FIPS mode. Remove DES2 from selftests.
- [Steve Henson]
-
- *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
- return internal method without any ENGINE dependencies. Add new
- tiny fips sign and verify functions.
- [Steve Henson]
-
- *) New build option no-ec2m to disable characteristic 2 code.
- [Steve Henson]
-
- *) New build option "fipscanisteronly". This only builds fipscanister.o
- and (currently) associated fips utilities. Uses the file Makefile.fips
- instead of Makefile.org as the prototype.
- [Steve Henson]
-
- *) Add some FIPS mode restrictions to GCM. Add internal IV generator.
- Update fips_gcmtest to use IV generator.
- [Steve Henson]
-
- *) Initial, experimental EVP support for AES-GCM. AAD can be input by
- setting output buffer to NULL. The *Final function must be
- called although it will not retrieve any additional data. The tag
- can be set or retrieved with a ctrl. The IV length is by default 12
- bytes (96 bits) but can be set to an alternative value. If the IV
- length exceeds the maximum IV length (currently 16 bytes) it cannot be
- set before the key.
- [Steve Henson]
-
- *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
- underlying do_cipher function handles all cipher semantics itself
- including padding and finalisation. This is useful if (for example)
- an ENGINE cipher handles block padding itself. The behaviour of
- do_cipher is subtly changed if this flag is set: the return value
- is the number of characters written to the output buffer (zero is
- no longer an error code) or a negative error code. Also if the
- input buffer is NULL and length 0 finalisation should be performed.
- [Steve Henson]
-
- *) If a candidate issuer certificate is already part of the constructed
- path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
- [Steve Henson]
-
- *) Improve forward-security support: add functions
-
- void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
- void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
-
- for use by SSL/TLS servers; the callback function will be called whenever a
- new session is created, and gets to decide whether the session may be
- cached to make it resumable (return 0) or not (return 1). (As by the
- SSL/TLS protocol specifications, the session_id sent by the server will be
- empty to indicate that the session is not resumable; also, the server will
- not generate RFC 4507 (RFC 5077) session tickets.)
-
- A simple reasonable callback implementation is to return is_forward_secure.
- This parameter will be set to 1 or 0 depending on the ciphersuite selected
- by the SSL/TLS server library, indicating whether it can provide forward
- security.
- [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
-
- *) New -verify_name option in command line utilities to set verification
- parameters by name.
- [Steve Henson]
-
- *) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
- Add CMAC pkey methods.
- [Steve Henson]
-
- *) Experimental renegotiation in s_server -www mode. If the client
- browses /reneg connection is renegotiated. If /renegcert it is
- renegotiated requesting a certificate.
- [Steve Henson]
-
- *) Add an "external" session cache for debugging purposes to s_server. This
- should help trace issues which normally are only apparent in deployed
- multi-process servers.
- [Steve Henson]
-
- *) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
- return value is ignored. NB. The functions RAND_add(), RAND_seed(),
- BIO_set_cipher() and some obscure PEM functions were changed so they
- can now return an error. The RAND changes required a change to the
- RAND_METHOD structure.
- [Steve Henson]
-
- *) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
- a gcc attribute to warn if the result of a function is ignored. This
- is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
- whose return value is often ignored.
