14 * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5,
15 don't use the optimized assembly for bignum multiplication. This removes
16 the need to pass -fomit-frame-pointer to avoid a build error with -O0.

Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200229 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
230 You now need to link to all of them if you use TLS for example.
231 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200232 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200233 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200234 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200235 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200236 mbedtls_cipher_info_t.key_length -> key_bitlen
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200237 mbedtls_cipher_context_t.key_length -> key_bitlen
Manuel Pégourié-Gonnardc34e8dd2015-04-28 21:42:17 +0200238 mbedtls_ecp_curve_info.size -> bit_size
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200239 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
240 * The following _init() functions that could return errors have
Tillmann Karras588ad502015-09-25 04:27:22 +0200241 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200242 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100243 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200244 mbedtls_ccm_init() -> mbedtls_ccm_setkey()
245 mbedtls_gcm_init() -> mbedtls_gcm_setkey()
246 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
247 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100248 Note that for mbedtls_ssl_setup(), you need to be done setting up the
249 ssl_config structure before calling it.
Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +0200250 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
251 ssl_set_session() and ssl_set_client_transport_id(), plus
252 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
253 (see rename.pl and compat-1.3.h above) and their first argument's type
254 changed from ssl_context to ssl_config.
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200255 * ssl_set_bio() changed signature (contexts merged, order switched, one
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100256 additional callback for read-with-timeout).
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200257 * The following functions have been introduced and must be used in callback
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100258 implementations (SNI, PSK) instead of their *conf counterparts:
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200259 mbedtls_ssl_set_hs_own_cert()
260 mbedtls_ssl_set_hs_ca_chain()
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200261 mbedtls_ssl_set_hs_psk()
262 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200263 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100264 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200265 pointer, parameters reordered).
266 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
267 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100268 * The SSL debug callback gained two new arguments (file name, line number).
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200269 * Debug modes were removed.
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100270 * mbedtls_ssl_conf_truncated_hmac() now returns void.
271 * mbedtls_memory_buffer_alloc_init() now returns void.
272 * X.509 verification flags are now an uint32_t. Affect the signature of:
273 mbedtls_ssl_get_verify_result()
274 mbedtls_x509_ctr_verify_info()
275 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200276 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
277 * The following functions changed prototype to avoid an in-out length
Manuel Pégourié-Gonnard0b104b02015-05-14 21:52:40 +0200278 parameter:
Manuel Pégourié-Gonnard8f5fd312015-04-24 14:42:34 +0200279 mbedtls_base64_encode()
280 mbedtls_base64_decode()
Manuel Pégourié-Gonnarddfdcac92015-03-31 11:41:42 +0200281 mbedtls_mpi_write_string()
282 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnardb8cfe3f2015-03-31 11:04:45 +0200283 * In the NET module, all "int" and "int *" arguments for file descriptors
Manuel Pégourié-Gonnard1cd10ad2015-06-23 11:07:37 +0200284 changed type to "mbedtls_net_context *".
285 * net_accept() gained new arguments for the size of the client_ip buffer.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100286 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
287 return void.
288 * ecdsa_write_signature() gained an addtional md_alg argument and
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100289 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200290 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
291 * Last argument of x509_crt_check_key_usage() and
292 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000293 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200294 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
295 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200296 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000297 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
298 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
Manuel Pégourié-Gonnard60c793b2015-06-18 20:52:58 +0200299 length parameter to include the terminating null byte for PEM input.
300 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200301 * calloc() is now used instead of malloc() everywhere. API of platform
302 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnardc0d74942015-06-23 12:30:57 +0200303 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200304 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
305 (support for renegotiation now needs explicit enabling in config.h).
306 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
Manuel Pégourié-Gonnardaff37e52015-05-11 18:11:57 +0200307 in config.h
Manuel Pégourié-Gonnard56cc88a2015-05-11 18:40:45 +0200308 * net_connect() and net_bind() have a new 'proto' argument to choose
309 between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
Manuel Pégourié-Gonnard41b9c2b2015-05-28 14:56:20 +0200310 Their 'port' argument type is changed to a string.
311 * Some constness fixes
312
Manuel Pégourié-Gonnarda63bc942015-05-14 18:22:47 +0200313Removals

Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200315 * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
316 mbedtls_ecp_muladd().
317 * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
318 (use generic functions from md.h)
319 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
320 waiting function.
321 * Removed test DHM parameters from the test certs module.
322 * Removed the PBKDF2 module (use PKCS5).
323 * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
324 * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
325 * Removed openssl.h (very partial OpenSSL compatibility layer).
Manuel Pégourié-Gonnard1022fed2015-03-27 16:30:47 +0100326 * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
327 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
328 been removed (compiler is required to support 32-bit operations).
329 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200330 * Removed test program o_p_test, the script compat.sh does more.

Manuel Pégourié-Gonnardc89d6cf2015-03-31 14:43:19 +0200334New deprecations
335 * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
Manuel Pégourié-Gonnard50518f42015-05-26 11:04:15 +0200336 argument (allowing memory savings if HMAC is not used)
337
Manuel Pégourié-Gonnard1d0ca1a2015-03-27 16:50:00 +0100338Semi-API changes (technically public, morally private)
Manuel Pégourié-Gonnard50518f42015-05-26 11:04:15 +0200339 * Renamed a few headers to include _internal in the name. Those headers are
340 not supposed to be included by users.

Manuel Pégourié-Gonnardfa44f202015-03-27 17:52:25 +0100348
Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200349Default behavior changes
350 * The default minimum TLS version is now TLS 1.0.
351 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100352 default ciphersuite list returned by ssl_list_ciphersuites()
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200353 * Support for receiving SSLv2 ClientHello is now disabled by default at

Manuel Pégourié-Gonnard662c6e82015-05-06 17:39:23 +0100355 * The default authmode for SSL/TLS clients is now REQUIRED.
Manuel Pégourié-Gonnardcb46fd82015-05-28 17:06:07 +0200356 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
357 enabled in the default configuration, this is only noticeable if using a
358 custom config.h
359 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.
360 * A minimum RSA key size of 2048 bits is now enforced during ceritificate
361 chain verification.
Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +0100362 * Negotiation of truncated HMAC is now disabled by default on server too.
Manuel Pégourié-Gonnardaff37e52015-05-11 18:11:57 +0200363 * The following functions are now case-sensitive:

370Requirement changes
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200371 * The minimum MSVC version required is now 2010 (better C99 support).
372 * The NET layer now unconditionnaly relies on getaddrinfo() and select().
373 * Compiler is required to support C99 types such as long long and uint32_t.
374

376 * ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio() with
377 new prototype, and mbedtls_ssl_set_read_timeout().
378 * The following functions now return void:
Manuel Pégourié-Gonnardabc729e2015-07-01 01:28:24 +0200379 mbedtls_ssl_conf_transport()
380 mbedtls_ssl_conf_max_version()
Manuel Pégourié-Gonnard1b511f92015-05-06 15:54:23 +0100381 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100382 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
383 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
384 an example implementation, see mbedtls_timing_delay_context and
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200385 mbedtls_timing_set/get_delay().
386 * With UDP sockets, it is no longer necessary to call net_bind() again
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100387 after a successful net_accept().
Manuel Pégourié-Gonnard7bf19762015-02-10 10:09:37 +0000388
389Changes
390 * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now

408 * Add support for reading DH parameters with privateValueLength included
Manuel Pégourié-Gonnardea0184b2015-02-16 15:42:16 +0000409 (contributed by Daniel Kahn Gillmor).
410 * Add support for bit strings in X.509 names (request by Fredrik Axelsson).
Manuel Pégourié-Gonnardad350ed2015-02-16 17:45:35 +0000411 * Add support for id-at-uniqueIdentifier in X.509 names.
412 * Add support for overriding snprintf() (except on Windows) and exit() in
413 the platform layer.
414 * Add an option to use macros instead of function pointers in the platform
415 layer (helps get rid of unwanted references).
416 * Improved Makefiles for Windows targets by fixing library targets and making
Manuel Pégourié-Gonnard8c3f0f42015-04-09 14:10:26 +0200417 cross-compilation easier (thanks to Alon Bar-Lev).
Manuel Pégourié-Gonnardf7dbedb2015-03-23 14:20:04 +0100418 * The benchmark program also prints heap usage for public-key primitives
Manuel Pégourié-Gonnard8c3f0f42015-04-09 14:10:26 +0200419 if POLARSSL_MEMORY_BUFFER_ALLOC_C and POLARSSL_MEMORY_DEBUG are defined.
Manuel Pégourié-Gonnardf7dbedb2015-03-23 14:20:04 +0100420 * New script ecc-heap.sh helps measuring the impact of ECC parameters on
Manuel Pégourié-Gonnard7bf19762015-02-10 10:09:37 +0000421 speed and RAM (heap only for now) usage.
422 * New script memory.sh helps measuring the ROM and RAM requirements of two
Manuel Pégourié-Gonnarddccb80b2015-06-03 10:20:33 +0100423 reduced configurations (PSK-CCM and NSA suite B).
Manuel Pégourié-Gonnardf2ec5052015-06-03 09:50:07 +0100424 * Add config flag POLARSSL_DEPRECATED_WARNING (off by default) to produce
