76Changes
77 * Extended test coverage of special cases, and added new timing test suite.
78 * Removed self-tests from the basic-built-test.sh script, and added all
79 missing self-tests to the test suites, to ensure self-tests are only
80 executed once.
81 * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len().
82 * Added support for a Yotta specific configuration file -
83 through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE.
Simon Butcher5908bcc2016-09-04 15:12:09 +010084 * Added optimization for code space for X.509/OID based on configured

88 net.c. For consistency, the corresponding header file, net.h, is marked as
89 deprecated, and its contents moved to net_sockets.h.
Simon Butcher59bffa22016-10-13 15:55:56 +010090 * Changed the strategy for X.509 certificate parsing and validation, to no
91 longer disregard certificates with unrecognised fields.

229 Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
230 of TLS, but might be in other uses. On 32 bit machines, requires reading a
231 string of close to or larger than 1GB to exploit; on 64 bit machines, would
232 require reading a string of close to or larger than 2^62 bytes.

Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200367 should generally be the first function called on this context after init:

Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100373 Note that for mbedtls_ssl_setup(), you need to be done setting up the
374 ssl_config structure before calling it.
Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +0200375 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),

Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100389 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200390 pointer, parameters reordered).
391 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
392 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100393 * The SSL debug callback gained two new arguments (file name, line number).

Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100411 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
412 return void.
413 * ecdsa_write_signature() gained an addtional md_alg argument and
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100414 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200415 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
416 * Last argument of x509_crt_check_key_usage() and
417 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000418 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200419 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
420 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200421 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000422 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
423 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
Manuel Pégourié-Gonnard60c793b2015-06-18 20:52:58 +0200424 length parameter to include the terminating null byte for PEM input.
425 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200426 * calloc() is now used instead of malloc() everywhere. API of platform
427 layer and the memory_buffer_alloc module changed accordingly.

Manuel Pégourié-Gonnard1b511f92015-05-06 15:54:23 +0100506 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100507 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
508 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
509 an example implementation, see mbedtls_timing_delay_context and
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200510 mbedtls_timing_set/get_delay().
511 * With UDP sockets, it is no longer necessary to call net_bind() again
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100512 after a successful net_accept().

1681 * The error codes have been remapped and combining error codes
1682 is now done with a PLUS instead of an OR as error codes
Paul Bakker831a7552011-05-18 13:32:51 +00001683 used are negative.
1684 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

1933= Version 0.9 released on 2008-03-16
1934
1935 * Added support for ciphersuite: SSL_RSA_AES_128_SHA
1936 * Enabled support for large files by default in aescrypt2.c
1937 * Preliminary openssl wrapper contributed by David Barrett
1938 * Fixed a bug in ssl_write() that caused the same payload to
1939 be sent twice in non-blocking mode when send returns EAGAIN
1940 * Fixed ssl_parse_client_hello(): session id and challenge must
1941 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
1942 * Added user-defined callback debug function (Krystian Kolodziej)
1943 * Before freeing a certificate, properly zero out all cert. data
1944 * Fixed the "mode" parameter so that encryption/decryption are
1945 not swapped on PadLock; also fixed compilation on older versions
1946 of gcc (bug reported by David Barrett)
1947 * Correctly handle the case in padlock_xcryptcbc() when input or
1948 ouput data is non-aligned by falling back to the software
1949 implementation, as VIA Nehemiah cannot handle non-aligned buffers
1950 * Fixed a memory leak in x509parse_crt() which was reported by Greg
1951 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to
1952 Matthew Page who reported several bugs
1953 * Fixed x509_get_ext() to accept some rare certificates which have
1954 an INTEGER instead of a BOOLEAN for BasicConstraints::cA.
1955 * Added support on the client side for the TLS "hostname" extension
1956 (patch contributed by David Patino)
1957 * Make x509parse_verify() return BADCERT_CN_MISMATCH when an empty
1958 string is passed as the CN (bug reported by spoofy)
1959 * Added an option to enable/disable the BN assembly code
1960 * Updated rsa_check_privkey() to verify that (D*E) = 1 % (P-1)*(Q-1)
1961 * Disabled obsolete hash functions by default (MD2, MD4); updated
1962 selftest and benchmark to not test ciphers that have been disabled
1963 * Updated x509parse_cert_info() to correctly display byte 0 of the
1964 serial number, setup correct server port in the ssl client example
1965 * Fixed a critical denial-of-service with X.509 cert. verification:
1966 peer may cause xyssl to loop indefinitely by sending a certificate
1967 for which the RSA signature check fails (bug reported by Benoit)
1968 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
1969 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
1970 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
1971 * Modified ssl_parse_client_key_exchange() to protect against
1972 Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well
1973 as the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
1974 * Updated rsa_gen_key() so that ctx->N is always nbits in size
1975 * Fixed assembly PPC compilation errors on Mac OS X, thanks to
1976 David Barrett and Dusan Semen
1977

1983 message digests, which fixes IE6/IE7 client authentication
1984 * Cleaned up the XYSSL* #defines, suggested by Azriel Fasten
1985 * Fixed net_recv(), thanks to Lorenz Schori and Egon Kocjan
1986 * Added user-defined callbacks for handling I/O and sessions
1987 * Added lots of debugging output in the SSL/TLS functions
1988 * Added preliminary X.509 cert. writing by Pascal Vizeli
1989 * Added preliminary support for the VIA PadLock routines
1990 * Added AES-CFB mode of operation, contributed by chmike
1991 * Added an SSL/TLS stress testing program (ssl_test.c)
