Manuel Pégourié-Gonnarda25ffc32015-06-25 12:01:16 +020050 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
51 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020052 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010053 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020054 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010055 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +020056 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +020057 mbedtls_cipher_info_t.key_length -> key_bitlen
58 mbedtls_cipher_context_t.key_length -> key_bitlen

Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020061 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +020062 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +020063 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +020064 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020065 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +020069 Note that for mbetls_ssl_setup(), you need to be done setting up the
70 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +010071 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +020072 ssl_set_session() and ssl_set_client_transport_id(), plus
73 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
74 (see rename.pl and compat-1.3.h above) and their first argument's type
75 changed from ssl_context to ssl_config.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +010076 * ssl_set_bio() changed signature (contexts merged, order switched, one

82 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +020083 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +010084 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +020085 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +010086 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +020087 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
88 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.

Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +020093 * X.509 verification flags are now an uint32_t. Affect the signature of:
94 mbedtls_ssl_get_verify_result()
95 mbedtls_x509_ctr_verify_info()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +010096 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)

Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +010098 * The following functions changed prototype to avoid an in-out length
99 parameter:
100 mbedtls_base64_encode()
101 mbedtls_base64_decode()
102 mbedtls_mpi_write_string()
103 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200104 * In the NET module, all "int" and "int *" arguments for file descriptors

115 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
116 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100117 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200118 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
119 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
120 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000121 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200122 * calloc() is now used instead of malloc() everywhere. API of platform
123 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200124 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000125 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
126 (support for renegotiation now needs explicit enabling in config.h).

Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +0100172 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
173 default ciphersuite list returned by ssl_list_ciphersuites()
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000174 * Support for receiving SSLv2 ClientHello is now disabled by default at

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200177 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
178 enabled in the default configuration, this is only noticeable if using a
179 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100180 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200181 * A minimum RSA key size of 2048 bits is now enforced during ceritificate

198 new prototype, and mbedtls_ssl_set_read_timeout().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200199 * The following functions now return void:
200 mbedtls_ssl_conf_transport()
201 mbedtls_ssl_conf_max_version()
202 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0c890352015-05-13 10:28:41 +0200203 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
204 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
205 an example implementation, see mbedtls_timing_delay_context and
