Manuel Pégourié-Gonnard4d7fbbf2014-10-15 15:40:55 +020010
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +020011API Changes
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020012 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010013 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020014 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +010015 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020016 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020017 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +020018 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +020019 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +020020 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020021 mbedtls_ccm_init() -> mbedtls_ccm_setkey()
Manuel Pégourié-Gonnardc34e8dd2015-04-28 21:42:17 +020022 mbedtls_gcm_init() -> mbedtls_gcm_setkey()
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +020023 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
24 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +020025 Note that for mbetls_ssl_setup(), you need to be done setting up the
26 ssl_config structure before calling it.
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +020027 * Most ssl_set_xxx() functions (all except ssl_set_hostname(),
28 ssl_set_session() and ssl_set_client_transport_id(), plus
29 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
30 (see rename.pl and compat-1.3.h above) and their first argument's type
31 changed from ssl_context to ssl_config.
Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +020032 * The following functions have been introduced and must be used in callback
33 implementations (SNI, PSK) instead of their *conf counterparts:
34 mbedtls_ssl_set_hs_own_cert()
35 mbedtls_ssl_set_hs_ca_chain()
36 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +020037 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +010038 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +020039 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +010040 pointer, parameters reordered).
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +020041 * mbedtls_ssl_conf_truncated_hmac() now returns void.
42 * mbedtls_memory_bufer_alloc_init() now returns void.
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +020043 * X.509 verification flags are now an uint32_t. Affect the signature of:
44 mbedtls_ssl_get_verify_result()
45 mbedtls_x509_ctr_verify_info()
46 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be update)
47 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnard8f5fd312015-04-24 14:42:34 +020048 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
49 return void.
Manuel Pégourié-Gonnarddfdcac92015-03-31 11:41:42 +020050 * ecdsa_write_signature() gained an addtional md_alg argument and
51 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnardb8cfe3f2015-03-31 11:04:45 +020052 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
Manuel Pégourié-Gonnard1d0ca1a2015-03-27 16:50:00 +010053 * Last argument of x509_crt_check_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +010054 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
55 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
56 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +010057 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +020058 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
59 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
60 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +000061 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +000062 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
63 (support for renegotiation now needs explicit enabling in config.h).
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +020064 * net_connect() and net_bind() have a new 'proto' argument to choose
65 between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
Manuel Pégourié-Gonnard1b511f92015-05-06 15:54:23 +010066 * ssl_set_bio() changed signature (contexts merged, order switched, one
67 additional callback for read-with-timeout).
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020068 * Some constness fixes

Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020074 * Removed individual mdX_hmac and shaX_hmac functions (use generic
75 md_hmac functions from md.h)
Manuel Pégourié-Gonnarda63bc942015-05-14 18:22:47 +020076 * Removed mbedtls_timing_msleep(). Use mbedtls_timing_usleep() or a custom
77 waiting function.

79 * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
80 * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
81 * Removed openssl.h (very partial OpenSSL compatibility layer).
82 * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
83 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
84 been removed (compiler is required to support 32-bit operations).
85 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
86 * Removed test program o_p_test, the script compat.sh does more.
87 * Removed test program ssl_test, superseded by ssl-opt.sh.

Manuel Pégourié-Gonnard1022fed2015-03-27 16:30:47 +010089
90New deprecations
91 * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
92 argument (allowing memory savings if HMAC is not used)
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +020093
Manuel Pégourié-Gonnard1022fed2015-03-27 16:30:47 +010094Semi-API changes (technically public, morally private)
Manuel Pégourié-Gonnardc89d6cf2015-03-31 14:43:19 +020095 * Changed md_info_t into an opaque structure (use md_get_xxx() accessors).

Manuel Pégourié-Gonnard1022fed2015-03-27 16:30:47 +0100102
Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +0100103Default behavior changes
Manuel Pégourié-Gonnard8c8be1e2015-03-31 14:21:11 +0200104 * The default minimum TLS version is now TLS 1.0.
Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +0100105 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200110 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
111 enabled in the default configuration, this is only noticeable if using a
112 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100113 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

Manuel Pégourié-Gonnard0c890352015-05-13 10:28:41 +0200128 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
129 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
130 an example implementation, see mbedtls_timing_delay_context and
131 mbedtls_timing_set/get_delay().
Manuel Pégourié-Gonnard1b511f92015-05-06 15:54:23 +0100132
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100133Changes
134 * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
135 thread-safe if MBEDTLS_THREADING_C is enabled.

139Security
Manuel Pégourié-Gonnard9f982512015-04-17 16:55:53 +0200140 * With authmode set to SSL_VERIFY_OPTIONAL, verification of keyUsage and
Manuel Pégourié-Gonnarde6efa6f2015-04-20 11:01:48 +0100141 extendedKeyUsage on the leaf certificate was lost (results not accessible

162 * New script ecc-heap.sh helps measuring the impact of ECC parameters on
163 speed and RAM (heap only for now) usage.
164 * New script memory.sh helps measuring the ROM and RAM requirements of two
165 reduced configurations (PSK-CCM and NSA suite B).
Manuel Pégourié-Gonnard8c3f0f42015-04-09 14:10:26 +0200166 * Add config flag POLARSSL_DEPRECATED_WARNING (off by default) to produce

1238 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +01001239 encountering a parse-error. Beware that the meaning of return values has
1240 changed!
Paul Bakker69e095c2011-12-10 21:55:01 +00001241 * All error codes are now negative. Even on mermory failures and IO errors.

1293 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001294 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001295 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1296 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001297 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1298 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1299 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1300 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001301 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
