233 * Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile() to allow
234 use of mbedtls_x509_crt_profile_next. (found by NWilson)
Manuel Pégourié-Gonnard14c25742015-09-08 15:12:45 +0200235 * When a client initiates a reconnect from the same port as a live
236 connection, if cookie verification is available
237 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
238 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
239 detected and mbedtls_ssl_read() will return
240 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
241 handshake with the same context. (See RFC 6347 section 4.2.8.)

312 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200313 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100314 Some names have been further changed to make them more consistent.

Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200317 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200318 mbedtls_cipher_info_t.key_length -> key_bitlen

Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200322 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200323 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200324 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200325 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200326 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Tillmann Karras588ad502015-09-25 04:27:22 +0200330 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200331 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100332 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200333 ssl_set_session() and ssl_set_client_transport_id(), plus
334 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()

341 mbedtls_ssl_set_hs_own_cert()
342 mbedtls_ssl_set_hs_ca_chain()
343 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200344 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100345 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200346 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100347 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200348 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
349 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200350 * The SSL debug callback gained two new arguments (file name, line number).
351 * Debug modes were removed.

Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100357 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200358 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100359 * The following functions changed prototype to avoid an in-out length
360 parameter:
361 mbedtls_base64_encode()
362 mbedtls_base64_decode()
363 mbedtls_mpi_write_string()
364 mbedtls_dhm_calc_secret()

Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100375 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
376 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
377 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100378 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200379 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
380 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
381 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000382 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200383 * calloc() is now used instead of malloc() everywhere. API of platform

409 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
410 been removed (compiler is required to support 32-bit operations).
411 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
412 * Removed test program o_p_test, the script compat.sh does more.
413 * Removed test program ssl_test, superseded by ssl-opt.sh.

1639 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001640 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001641 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1642 net_recv() now returns 0 on EOF instead of
