73 once in the same handhake and mbedtls_ssl_conf_psk() was used.
Simon Butcherc48b66b2015-10-05 10:18:17 +010074 Found and patch provided by Guido Vranken, Intelworks. Cannot be forced
75 remotely.

127 * Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile() to allow

Manuel Pégourié-Gonnard14c25742015-09-08 15:12:45 +0200129 * When a client initiates a reconnect from the same port as a live
130 connection, if cookie verification is available
131 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
132 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
133 detected and mbedtls_ssl_read() will return
134 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
135 handshake with the same context. (See RFC 6347 section 4.2.8.)

236 mbedtls_ssl_set_hs_ca_chain()
237 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200238 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set

Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200252 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100253 * The following functions changed prototype to avoid an in-out length
254 parameter:
255 mbedtls_base64_encode()
256 mbedtls_base64_decode()
257 mbedtls_mpi_write_string()
258 mbedtls_dhm_calc_secret()

Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100272 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200273 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
274 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
275 length parameter to include the terminating null byte for PEM input.

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200332 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
333 enabled in the default configuration, this is only noticeable if using a
334 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100335 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

355 mbedtls_ssl_conf_transport()
356 mbedtls_ssl_conf_max_version()
357 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0c890352015-05-13 10:28:41 +0200358 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
359 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
360 an example implementation, see mbedtls_timing_delay_context and
361 mbedtls_timing_set/get_delay().
Manuel Pégourié-Gonnardabc729e2015-07-01 01:28:24 +0200362 * With UDP sockets, it is no longer necessary to call net_bind() again
363 after a successful net_accept().

Paul Bakker7eb013f2011-10-06 12:37:39 +00001455
Paul Bakkerca6f3e22011-10-06 13:11:08 +00001456Changes

Paul Bakkera35aa542013-03-06 17:06:21 +01001479 encountering a parse-error. Beware that the meaning of return values has
1480 changed!

1514 * Added additional Cipher Block Modes to symmetric ciphers
1515 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +01001516 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00001517 * Functions requiring File System functions can now be disabled
1518 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001519 * A error_strerror function() has been added to translate between

1526 * Major argument / variable rewrite. Introduced use of size_t
1527 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001528 better unsigned / signed use. Renamed internal bigint types
1529 t_int and t_dbl to t_uint and t_udbl in the process

1531 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001532 * The error codes have been remapped and combining error codes
1533 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001534 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001535 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1536 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001537 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1538 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1539 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1540 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001541 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

1556 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +00001557 * x509parse_key() (and as a consequence x509parse_keyfile())
1558 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001559 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001560
