Manuel Pégourié-Gonnarda25ffc32015-06-25 12:01:16 +020081 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
82 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020083 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010084 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020085 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010086 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +020087 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +020088 mbedtls_cipher_info_t.key_length -> key_bitlen
89 mbedtls_cipher_context_t.key_length -> key_bitlen

Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020091 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020092 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +020093 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +020094 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +020095 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020096 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200100 Note that for mbetls_ssl_setup(), you need to be done setting up the
101 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100102 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200103 ssl_set_session() and ssl_set_client_transport_id(), plus
104 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
105 (see rename.pl and compat-1.3.h above) and their first argument's type
106 changed from ssl_context to ssl_config.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100107 * ssl_set_bio() changed signature (contexts merged, order switched, one

110 implementations (SNI, PSK) instead of their *conf counterparts:
111 mbedtls_ssl_set_hs_own_cert()
112 mbedtls_ssl_set_hs_ca_chain()
113 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200114 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100115 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200116 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100117 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200118 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
119 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200120 * The SSL debug callback gained two new arguments (file name, line number).
121 * Debug modes were removed.
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200122 * mbedtls_ssl_conf_truncated_hmac() now returns void.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100123 * mbedtls_memory_buffer_alloc_init() now returns void.
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200124 * X.509 verification flags are now an uint32_t. Affect the signature of:
125 mbedtls_ssl_get_verify_result()
126 mbedtls_x509_ctr_verify_info()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100127 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200128 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100129 * The following functions changed prototype to avoid an in-out length
130 parameter:
131 mbedtls_base64_encode()
132 mbedtls_base64_decode()
133 mbedtls_mpi_write_string()
134 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200135 * In the NET module, all "int" and "int *" arguments for file descriptors
136 changed type to "mbedtls_net_context *".
Manuel Pégourié-Gonnard0b104b02015-05-14 21:52:40 +0200137 * net_accept() gained new arguments for the size of the client_ip buffer.
Manuel Pégourié-Gonnard8f5fd312015-04-24 14:42:34 +0200138 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
139 return void.
Manuel Pégourié-Gonnarddfdcac92015-03-31 11:41:42 +0200140 * ecdsa_write_signature() gained an addtional md_alg argument and
141 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnardb8cfe3f2015-03-31 11:04:45 +0200142 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
Manuel Pégourié-Gonnard1cd10ad2015-06-23 11:07:37 +0200143 * Last argument of x509_crt_check_key_usage() and
144 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100145 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
146 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
147 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100148 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200149 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
150 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
151 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000152 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200153 * calloc() is now used instead of malloc() everywhere. API of platform
154 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200155 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000156 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
157 (support for renegotiation now needs explicit enabling in config.h).

170 (use generic functions from md.h)
171 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
Manuel Pégourié-Gonnarda63bc942015-05-14 18:22:47 +0200172 waiting function.

178 * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
179 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
180 been removed (compiler is required to support 32-bit operations).
181 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
182 * Removed test program o_p_test, the script compat.sh does more.
183 * Removed test program ssl_test, superseded by ssl-opt.sh.

Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200189
Manuel Pégourié-Gonnard1022fed2015-03-27 16:30:47 +0100190Semi-API changes (technically public, morally private)
Manuel Pégourié-Gonnard50518f42015-05-26 11:04:15 +0200191 * Renamed a few headers to include _internal in the name. Those headers are
192 not supposed to be included by users.
Manuel Pégourié-Gonnardc89d6cf2015-03-31 14:43:19 +0200193 * Changed md_info_t into an opaque structure (use md_get_xxx() accessors).

Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +0100203 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
204 default ciphersuite list returned by ssl_list_ciphersuites()
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000205 * Support for receiving SSLv2 ClientHello is now disabled by default at

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200208 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
209 enabled in the default configuration, this is only noticeable if using a
210 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100211 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

1409 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001410 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001411 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

1416 after the handshake.
