20 tries to continue the handshake after it failed (a misuse of the API).
Simon Butcher8f988422015-09-22 10:10:36 +010021 (Found and patch provided by Fabian Foerg, Gotham Digital Science using afl-fuzz.)
Manuel Pégourié-Gonnardc2ed8022015-09-09 12:15:13 +020022

Manuel Pégourié-Gonnard14c25742015-09-08 15:12:45 +020031 * When a client initiates a reconnect from the same port as a live
32 connection, if cookie verification is available
33 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
34 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
35 detected and mbedtls_ssl_read() will return
36 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
37 handshake with the same context. (See RFC 6347 section 4.2.8.)

Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200111 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100112 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200113 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200114 mbedtls_cipher_info_t.key_length -> key_bitlen
115 mbedtls_cipher_context_t.key_length -> key_bitlen

Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200118 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200119 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200120 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200121 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200122 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Tillmann Karras588ad502015-09-25 04:27:22 +0200126 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200127 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100128 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200129 ssl_set_session() and ssl_set_client_transport_id(), plus
130 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
131 (see rename.pl and compat-1.3.h above) and their first argument's type
132 changed from ssl_context to ssl_config.

136 implementations (SNI, PSK) instead of their *conf counterparts:
137 mbedtls_ssl_set_hs_own_cert()
138 mbedtls_ssl_set_hs_ca_chain()
139 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200140 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100141 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200142 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100143 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200144 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
145 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200146 * The SSL debug callback gained two new arguments (file name, line number).
147 * Debug modes were removed.
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200148 * mbedtls_ssl_conf_truncated_hmac() now returns void.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100149 * mbedtls_memory_buffer_alloc_init() now returns void.
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200150 * X.509 verification flags are now an uint32_t. Affect the signature of:

Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100155 * The following functions changed prototype to avoid an in-out length
156 parameter:
157 mbedtls_base64_encode()
158 mbedtls_base64_decode()
159 mbedtls_mpi_write_string()
160 mbedtls_dhm_calc_secret()

Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100171 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
172 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
173 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100174 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200175 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
176 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
177 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000178 * Signature of mpi_mul_mpi() changed to make the last argument unsigned

196 (use generic functions from md.h)
197 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
Manuel Pégourié-Gonnarda63bc942015-05-14 18:22:47 +0200198 waiting function.

1435 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001436 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001437 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1438 net_recv() now returns 0 on EOF instead of

1440 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1441 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1442 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001443 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
