markrad 0:cdf462088d13 12 Security
markrad 0:cdf462088d13 13 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
markrad 0:cdf462088d13 14 with RFC-5116 and could lead to session key recovery in very long TLS
markrad 0:cdf462088d13 15 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in
markrad 0:cdf462088d13 16 TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.
markrad 0:cdf462088d13 17 https://eprint.iacr.org/2016/475.pdf
markrad 0:cdf462088d13 18 * Fixed potential stack corruption in mbedtls_x509write_crt_der() and
markrad 0:cdf462088d13 19 mbedtls_x509write_csr_der() when the signature is copied to the buffer
markrad 0:cdf462088d13 20 without checking whether there is enough space in the destination. The
markrad 0:cdf462088d13 21 issue cannot be triggered remotely. Found by Jethro Beekman.
markrad 0:cdf462088d13 22
markrad 0:cdf462088d13 23 Features
markrad 0:cdf462088d13 24 * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by
markrad 0:cdf462088d13 25 NIST SP 800-38B, RFC-4493 and RFC-4615.
markrad 0:cdf462088d13 26 * Added hardware entropy selftest to verify that the hardware entropy source
markrad 0:cdf462088d13 27 is functioning correctly.
markrad 0:cdf462088d13 28 * Added a script to print build environment info for diagnostic use in test
markrad 0:cdf462088d13 29 scripts, which is also now called by all.sh.
markrad 0:cdf462088d13 30 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
markrad 0:cdf462088d13 31 configure the maximum length of a file path that can be buffered when
markrad 0:cdf462088d13 32 calling mbedtls_x509_crt_parse_path().
markrad 0:cdf462088d13 33 * Added a configuration file config-no-entropy.h that configures the subset of
markrad 0:cdf462088d13 34 library features that do not require an entropy source.
markrad 0:cdf462088d13 35 * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users
markrad 0:cdf462088d13 36 to configure the minimum number of bytes for entropy sources using the
markrad 0:cdf462088d13 37 mbedtls_hardware_poll() function.
markrad 0:cdf462088d13 38
markrad 0:cdf462088d13 39 Bugfix
markrad 0:cdf462088d13 40 * Fix for platform time abstraction to avoid dependency issues where a build
markrad 0:cdf462088d13 41 may need time but not the standard C library abstraction, and added
markrad 0:cdf462088d13 42 configuration consistency checks to check_config.h
markrad 0:cdf462088d13 43 * Fix dependency issue in Makefile to allow parallel builds.
markrad 0:cdf462088d13 44 * Fix incorrect handling of block lengths in crypt_and_hash.c sample program,
markrad 0:cdf462088d13 45 when GCM is used. Found by udf2457. #441
markrad 0:cdf462088d13 46 * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't
markrad 0:cdf462088d13 47 enabled unless others were also present. Found by David Fernandez. #428
markrad 0:cdf462088d13 48 * Fix for out-of-tree builds using CMake. Found by jwurzer, and fix based on
markrad 0:cdf462088d13 49 a contribution from Tobias Tangemann. #541
markrad 0:cdf462088d13 50 * Fixed cert_app.c sample program for debug output and for use when no root
markrad 0:cdf462088d13 51 certificates are provided.
markrad 0:cdf462088d13 52 * Fix conditional statement that would cause a 1 byte overread in
markrad 0:cdf462088d13 53 mbedtls_asn1_get_int(). Found and fixed by Guido Vranken. #599
markrad 0:cdf462088d13 54 * Fixed pthread implementation to avoid unintended double initialisations
markrad 0:cdf462088d13 55 and double frees. Found by Niklas Amnebratt.
markrad 0:cdf462088d13 56 * Fixed the sample applications gen_key.c, cert_req.c and cert_write.c for
markrad 0:cdf462088d13 57 builds where the configuration MBEDTLS_PEM_WRITE_C is not defined. Found
markrad 0:cdf462088d13 58 by inestlerode. #559.
markrad 0:cdf462088d13 59 * Fix mbedtls_x509_get_sig() to update the ASN1 type in the mbedtls_x509_buf
markrad 0:cdf462088d13 60 data structure until after error checks are successful. Found by
markrad 0:cdf462088d13 61 subramanyam-c. #622
markrad 0:cdf462088d13 62 * Fix documentation and implementation missmatch for function arguments of
markrad 0:cdf462088d13 63 mbedtls_gcm_finish(). Found by cmiatpaar. #602
markrad 0:cdf462088d13 64 * Guarantee that P>Q at RSA key generation. Found by inestlerode. #558
markrad 0:cdf462088d13 65 * Fix potential byte overread when verifying malformed SERVER_HELLO in

markrad 0:cdf462088d13 67 * Fix check for validity of date when parsing in mbedtls_x509_get_time().
markrad 0:cdf462088d13 68 Found by subramanyam-c. #626
markrad 0:cdf462088d13 69 * Fix compatibility issue with Internet Explorer client authentication,
markrad 0:cdf462088d13 70 where the limited hash choices prevented the client from sending its
markrad 0:cdf462088d13 71 certificate. Found by teumas. #513
markrad 0:cdf462088d13 72 * Fix compilation without MBEDTLS_SELF_TEST enabled.
markrad 0:cdf462088d13 73
markrad 0:cdf462088d13 74 Changes
markrad 0:cdf462088d13 75 * Extended test coverage of special cases, and added new timing test suite.
markrad 0:cdf462088d13 76 * Removed self-tests from the basic-built-test.sh script, and added all
markrad 0:cdf462088d13 77 missing self-tests to the test suites, to ensure self-tests are only
markrad 0:cdf462088d13 78 executed once.
markrad 0:cdf462088d13 79 * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len().
markrad 0:cdf462088d13 80 * Added support for a Yotta specific configuration file -
markrad 0:cdf462088d13 81 through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE.
markrad 0:cdf462088d13 82 * Added optimization for code space for X.509/OID based on configured
markrad 0:cdf462088d13 83 features. Contributed by Aviv Palivoda.
markrad 0:cdf462088d13 84 * Renamed source file library/net.c to library/net_sockets.c to avoid
markrad 0:cdf462088d13 85 naming collision in projects which also have files with the common name
markrad 0:cdf462088d13 86 net.c. For consistency, the corresponding header file, net.h, is marked as
markrad 0:cdf462088d13 87 deprecated, and its contents moved to net_sockets.h.
markrad 0:cdf462088d13 88 * Changed the strategy for X.509 certificate parsing and validation, to no
markrad 0:cdf462088d13 89 longer disregard certificates with unrecognised fields.

markrad 0:cdf462088d13 95 required by PKCS1 v2.2
markrad 0:cdf462088d13 96 * Fix potential integer overflow to buffer overflow in
markrad 0:cdf462088d13 97 mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt
markrad 0:cdf462088d13 98 (not triggerable remotely in (D)TLS).
markrad 0:cdf462088d13 99 * Fix a potential integer underflow to buffer overread in
markrad 0:cdf462088d13 100 mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in
markrad 0:cdf462088d13 101 SSL/TLS.
markrad 0:cdf462088d13 102
markrad 0:cdf462088d13 103 Features

markrad 0:cdf462088d13 106
markrad 0:cdf462088d13 107 Bugfix
markrad 0:cdf462088d13 108 * Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three
markrad 0:cdf462088d13 109 arguments where the same (in-place doubling). Found and fixed by Janos
markrad 0:cdf462088d13 110 Follath. #309
markrad 0:cdf462088d13 111 * Fix potential build failures related to the 'apidoc' target, introduced
markrad 0:cdf462088d13 112 in the previous patch release. Found by Robert Scheck. #390 #391
markrad 0:cdf462088d13 113 * Fix issue in Makefile that prevented building using armar. #386
markrad 0:cdf462088d13 114 * Fix memory leak that occured only when ECJPAKE was enabled and ECDHE and
markrad 0:cdf462088d13 115 ECDSA was disabled in config.h . The leak didn't occur by default.
markrad 0:cdf462088d13 116 * Fix an issue that caused valid certificates to be rejected whenever an
markrad 0:cdf462088d13 117 expired or not yet valid certificate was parsed before a valid certificate
markrad 0:cdf462088d13 118 in the trusted certificate list.
markrad 0:cdf462088d13 119 * Fix bug in mbedtls_x509_crt_parse that caused trailing extra data in the
markrad 0:cdf462088d13 120 buffer after DER certificates to be included in the raw representation.
markrad 0:cdf462088d13 121 * Fix issue that caused a hang when generating RSA keys of odd bitlength
markrad 0:cdf462088d13 122 * Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made null pointer
markrad 0:cdf462088d13 123 dereference possible.
markrad 0:cdf462088d13 124 * Fix issue that caused a crash if invalid curves were passed to
markrad 0:cdf462088d13 125 mbedtls_ssl_conf_curves. #373
markrad 0:cdf462088d13 126 * Fix issue in ssl_fork_server which was preventing it from functioning. #429
markrad 0:cdf462088d13 127 * Fix memory leaks in test framework
markrad 0:cdf462088d13 128 * Fix test in ssl-opt.sh that does not run properly with valgrind
markrad 0:cdf462088d13 129 * Fix unchecked calls to mmbedtls_md_setup(). Fix by Brian Murray. #502
markrad 0:cdf462088d13 130
markrad 0:cdf462088d13 131 Changes
markrad 0:cdf462088d13 132 * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5,
markrad 0:cdf462088d13 133 don't use the optimized assembly for bignum multiplication. This removes
markrad 0:cdf462088d13 134 the need to pass -fomit-frame-pointer to avoid a build error with -O0.
markrad 0:cdf462088d13 135 * Disabled SSLv3 in the default configuration.
markrad 0:cdf462088d13 136 * Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey
markrad 0:cdf462088d13 137 Skalozub).
markrad 0:cdf462088d13 138 * Fix non-compliance server extension handling. Extensions for SSLv3 are now
markrad 0:cdf462088d13 139 ignored, as required by RFC6101.

markrad 0:cdf462088d13 144 * Fix potential double free when mbedtls_asn1_store_named_data() fails to
markrad 0:cdf462088d13 145 allocate memory. Only used for certificate generation, not triggerable
markrad 0:cdf462088d13 146 remotely in SSL/TLS. Found by Rafał Przywara. #367
markrad 0:cdf462088d13 147 * Disable MD5 handshake signatures in TLS 1.2 by default to prevent the
markrad 0:cdf462088d13 148 SLOTH attack on TLS 1.2 server authentication (other attacks from the
markrad 0:cdf462088d13 149 SLOTH paper do not apply to any version of mbed TLS or PolarSSL).

markrad 0:cdf462088d13 159 * Fix suboptimal handling of unexpected records that caused interop issues
markrad 0:cdf462088d13 160 with some peers over unreliable links. Avoid dropping an entire DTLS
markrad 0:cdf462088d13 161 datagram if a single record in a datagram is unexpected, instead only
markrad 0:cdf462088d13 162 drop the record and look at subsequent records (if any are present) in
markrad 0:cdf462088d13 163 the same datagram. Found by jeannotlapin. #345
markrad 0:cdf462088d13 164
markrad 0:cdf462088d13 165 = mbed TLS 2.2.0 released 2015-11-04

markrad 0:cdf462088d13 171 * Fix potential heap corruption on Windows when
markrad 0:cdf462088d13 172 mbedtls_x509_crt_parse_path() is passed a path longer than 2GB. Cannot be
markrad 0:cdf462088d13 173 triggered remotely. Found by Guido Vranken, Intelworks.
markrad 0:cdf462088d13 174 * Fix potential buffer overflow in some asn1_write_xxx() functions.
markrad 0:cdf462088d13 175 Cannot be triggered remotely unless you create X.509 certificates based
markrad 0:cdf462088d13 176 on untrusted input or write keys of untrusted origin. Found by Guido
markrad 0:cdf462088d13 177 Vranken, Intelworks.
markrad 0:cdf462088d13 178 * The X509 max_pathlen constraint was not enforced on intermediate

markrad 0:cdf462088d13 186 block. (Potential uses include EAP-TLS and Thread.)
markrad 0:cdf462088d13 187
markrad 0:cdf462088d13 188 Bugfix
markrad 0:cdf462088d13 189 * Self-signed certificates were not excluded from pathlen counting,
markrad 0:cdf462088d13 190 resulting in some valid X.509 being incorrectly rejected. Found and fix
markrad 0:cdf462088d13 191 provided by Janos Follath. #319
markrad 0:cdf462088d13 192 * Fix build error with configurations where ECDHE-PSK is the only key
markrad 0:cdf462088d13 193 exchange. Found and fix provided by Chris Hammond. #270
markrad 0:cdf462088d13 194 * Fix build error with configurations where RSA, RSA-PSK, ECDH-RSA or

markrad 0:cdf462088d13 214
markrad 0:cdf462088d13 215 Security
markrad 0:cdf462088d13 216 * Added fix for CVE-2015-5291 to prevent heap corruption due to buffer
markrad 0:cdf462088d13 217 overflow of the hostname or session ticket. Found by Guido Vranken,
markrad 0:cdf462088d13 218 Intelworks.
markrad 0:cdf462088d13 219 * Fix potential double-free if mbedtls_ssl_set_hs_psk() is called more than
markrad 0:cdf462088d13 220 once in the same handhake and mbedtls_ssl_conf_psk() was used.
markrad 0:cdf462088d13 221 Found and patch provided by Guido Vranken, Intelworks. Cannot be forced
markrad 0:cdf462088d13 222 remotely.
markrad 0:cdf462088d13 223 * Fix stack buffer overflow in pkcs12 decryption (used by
markrad 0:cdf462088d13 224 mbedtls_pk_parse_key(file)() when the password is > 129 bytes.
markrad 0:cdf462088d13 225 Found by Guido Vranken, Intelworks. Not triggerable remotely.
markrad 0:cdf462088d13 226 * Fix potential buffer overflow in mbedtls_mpi_read_string().
markrad 0:cdf462088d13 227 Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
markrad 0:cdf462088d13 228 of TLS, but might be in other uses. On 32 bit machines, requires reading a
markrad 0:cdf462088d13 229 string of close to or larger than 1GB to exploit; on 64 bit machines, would
markrad 0:cdf462088d13 230 require reading a string of close to or larger than 2^62 bytes.
markrad 0:cdf462088d13 231 * Fix potential random memory allocation in mbedtls_pem_read_buffer()
markrad 0:cdf462088d13 232 on crafted PEM input data. Found and fix provided by Guido Vranken,
markrad 0:cdf462088d13 233 Intelworks. Not triggerable remotely in TLS. Triggerable remotely if you
markrad 0:cdf462088d13 234 accept PEM data from an untrusted source.
markrad 0:cdf462088d13 235 * Fix possible heap buffer overflow in base64_encoded() when the input

markrad 0:cdf462088d13 237 Intelworks. Not trigerrable remotely in TLS.
markrad 0:cdf462088d13 238 * Fix potential double-free if mbedtls_conf_psk() is called repeatedly on
markrad 0:cdf462088d13 239 the same mbedtls_ssl_config object and memory allocation fails. Found by
markrad 0:cdf462088d13 240 Guido Vranken, Intelworks. Cannot be forced remotely.
markrad 0:cdf462088d13 241 * Fix potential heap buffer overflow in servers that perform client
markrad 0:cdf462088d13 242 authentication against a crafted CA cert. Cannot be triggered remotely
markrad 0:cdf462088d13 243 unless you allow third parties to pick trust CAs for client auth.

markrad 0:cdf462088d13 273 Changes
markrad 0:cdf462088d13 274 * Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile() to allow
markrad 0:cdf462088d13 275 use of mbedtls_x509_crt_profile_next. (found by NWilson)
markrad 0:cdf462088d13 276 * When a client initiates a reconnect from the same port as a live
markrad 0:cdf462088d13 277 connection, if cookie verification is available
markrad 0:cdf462088d13 278 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
markrad 0:cdf462088d13 279 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
markrad 0:cdf462088d13 280 detected and mbedtls_ssl_read() will return
markrad 0:cdf462088d13 281 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
markrad 0:cdf462088d13 282 handshake with the same context. (See RFC 6347 section 4.2.8.)

markrad 0:cdf462088d13 335 = mbed TLS 2.0.0 released 2015-07-13
markrad 0:cdf462088d13 336
markrad 0:cdf462088d13 337 Features
markrad 0:cdf462088d13 338 * Support for DTLS 1.0 and 1.2 (RFC 6347).
markrad 0:cdf462088d13 339 * Ability to override core functions from MDx, SHAx, AES and DES modules
markrad 0:cdf462088d13 340 with custom implementation (eg hardware accelerated), complementing the
markrad 0:cdf462088d13 341 ability to override the whole module.
markrad 0:cdf462088d13 342 * New server-side implementation of session tickets that rotate keys to
markrad 0:cdf462088d13 343 preserve forward secrecy, and allows sharing across multiple contexts.
markrad 0:cdf462088d13 344 * Added a concept of X.509 cerificate verification profile that controls
markrad 0:cdf462088d13 345 which algorithms and key sizes (curves for ECDSA) are acceptable.
markrad 0:cdf462088d13 346 * Expanded configurability of security parameters in the SSL module with
markrad 0:cdf462088d13 347 mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
markrad 0:cdf462088d13 348 * Introduced a concept of presets for SSL security-relevant configuration
markrad 0:cdf462088d13 349 parameters.
markrad 0:cdf462088d13 350
markrad 0:cdf462088d13 351 API Changes
markrad 0:cdf462088d13 352 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
markrad 0:cdf462088d13 353 You now need to link to all of them if you use TLS for example.
markrad 0:cdf462088d13 354 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
markrad 0:cdf462088d13 355 Some names have been further changed to make them more consistent.
markrad 0:cdf462088d13 356 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
markrad 0:cdf462088d13 357 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
markrad 0:cdf462088d13 358 * Renamings of fields inside structures, not covered by the previous list:
markrad 0:cdf462088d13 359 mbedtls_cipher_info_t.key_length -> key_bitlen
markrad 0:cdf462088d13 360 mbedtls_cipher_context_t.key_length -> key_bitlen
markrad 0:cdf462088d13 361 mbedtls_ecp_curve_info.size -> bit_size
markrad 0:cdf462088d13 362 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
markrad 0:cdf462088d13 363 * The following _init() functions that could return errors have
markrad 0:cdf462088d13 364 been split into an _init() that returns void and another function that
markrad 0:cdf462088d13 365 should generally be the first function called on this context after init:
markrad 0:cdf462088d13 366 mbedtls_ssl_init() -> mbedtls_ssl_setup()
markrad 0:cdf462088d13 367 mbedtls_ccm_init() -> mbedtls_ccm_setkey()
markrad 0:cdf462088d13 368 mbedtls_gcm_init() -> mbedtls_gcm_setkey()
markrad 0:cdf462088d13 369 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
markrad 0:cdf462088d13 370 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
markrad 0:cdf462088d13 371 Note that for mbedtls_ssl_setup(), you need to be done setting up the
markrad 0:cdf462088d13 372 ssl_config structure before calling it.
markrad 0:cdf462088d13 373 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
markrad 0:cdf462088d13 374 ssl_set_session() and ssl_set_client_transport_id(), plus
markrad 0:cdf462088d13 375 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
markrad 0:cdf462088d13 376 (see rename.pl and compat-1.3.h above) and their first argument's type
markrad 0:cdf462088d13 377 changed from ssl_context to ssl_config.
markrad 0:cdf462088d13 378 * ssl_set_bio() changed signature (contexts merged, order switched, one
markrad 0:cdf462088d13 379 additional callback for read-with-timeout).
markrad 0:cdf462088d13 380 * The following functions have been introduced and must be used in callback
markrad 0:cdf462088d13 381 implementations (SNI, PSK) instead of their *conf counterparts:
markrad 0:cdf462088d13 382 mbedtls_ssl_set_hs_own_cert()
markrad 0:cdf462088d13 383 mbedtls_ssl_set_hs_ca_chain()
markrad 0:cdf462088d13 384 mbedtls_ssl_set_hs_psk()
markrad 0:cdf462088d13 385 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
markrad 0:cdf462088d13 386 using mbedtls_ssl_set_hostname().
markrad 0:cdf462088d13 387 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
markrad 0:cdf462088d13 388 pointer, parameters reordered).
markrad 0:cdf462088d13 389 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
markrad 0:cdf462088d13 390 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
markrad 0:cdf462088d13 391 * The SSL debug callback gained two new arguments (file name, line number).
markrad 0:cdf462088d13 392 * Debug modes were removed.
markrad 0:cdf462088d13 393 * mbedtls_ssl_conf_truncated_hmac() now returns void.
markrad 0:cdf462088d13 394 * mbedtls_memory_buffer_alloc_init() now returns void.
markrad 0:cdf462088d13 395 * X.509 verification flags are now an uint32_t. Affect the signature of:
markrad 0:cdf462088d13 396 mbedtls_ssl_get_verify_result()
markrad 0:cdf462088d13 397 mbedtls_x509_ctr_verify_info()
markrad 0:cdf462088d13 398 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
markrad 0:cdf462088d13 399 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
markrad 0:cdf462088d13 400 * The following functions changed prototype to avoid an in-out length
markrad 0:cdf462088d13 401 parameter:
markrad 0:cdf462088d13 402 mbedtls_base64_encode()
markrad 0:cdf462088d13 403 mbedtls_base64_decode()
markrad 0:cdf462088d13 404 mbedtls_mpi_write_string()
markrad 0:cdf462088d13 405 mbedtls_dhm_calc_secret()
markrad 0:cdf462088d13 406 * In the NET module, all "int" and "int *" arguments for file descriptors
markrad 0:cdf462088d13 407 changed type to "mbedtls_net_context *".
markrad 0:cdf462088d13 408 * net_accept() gained new arguments for the size of the client_ip buffer.
markrad 0:cdf462088d13 409 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
markrad 0:cdf462088d13 410 return void.
markrad 0:cdf462088d13 411 * ecdsa_write_signature() gained an addtional md_alg argument and
markrad 0:cdf462088d13 412 ecdsa_write_signature_det() was deprecated.
markrad 0:cdf462088d13 413 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
markrad 0:cdf462088d13 414 * Last argument of x509_crt_check_key_usage() and
markrad 0:cdf462088d13 415 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
markrad 0:cdf462088d13 416 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
markrad 0:cdf462088d13 417 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
markrad 0:cdf462088d13 418 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
markrad 0:cdf462088d13 419 strings; use the new *_len variables instead of strlen().
markrad 0:cdf462088d13 420 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
markrad 0:cdf462088d13 421 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
markrad 0:cdf462088d13 422 length parameter to include the terminating null byte for PEM input.
markrad 0:cdf462088d13 423 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
markrad 0:cdf462088d13 424 * calloc() is now used instead of malloc() everywhere. API of platform
markrad 0:cdf462088d13 425 layer and the memory_buffer_alloc module changed accordingly.
markrad 0:cdf462088d13 426 (Thanks to Mansour Moufid for helping with the replacement.)
markrad 0:cdf462088d13 427 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
markrad 0:cdf462088d13 428 (support for renegotiation now needs explicit enabling in config.h).
markrad 0:cdf462088d13 429 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
markrad 0:cdf462088d13 430 in config.h
markrad 0:cdf462088d13 431 * net_connect() and net_bind() have a new 'proto' argument to choose
markrad 0:cdf462088d13 432 between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
markrad 0:cdf462088d13 433 Their 'port' argument type is changed to a string.
markrad 0:cdf462088d13 434 * Some constness fixes
markrad 0:cdf462088d13 435
markrad 0:cdf462088d13 436 Removals
markrad 0:cdf462088d13 437 * Removed mbedtls_ecp_group_read_string(). Only named groups are supported.
markrad 0:cdf462088d13 438 * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
markrad 0:cdf462088d13 439 mbedtls_ecp_muladd().
markrad 0:cdf462088d13 440 * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
markrad 0:cdf462088d13 441 (use generic functions from md.h)
markrad 0:cdf462088d13 442 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
markrad 0:cdf462088d13 443 waiting function.
markrad 0:cdf462088d13 444 * Removed test DHM parameters from the test certs module.
markrad 0:cdf462088d13 445 * Removed the PBKDF2 module (use PKCS5).
markrad 0:cdf462088d13 446 * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
markrad 0:cdf462088d13 447 * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
markrad 0:cdf462088d13 448 * Removed openssl.h (very partial OpenSSL compatibility layer).
markrad 0:cdf462088d13 449 * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
markrad 0:cdf462088d13 450 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
markrad 0:cdf462088d13 451 been removed (compiler is required to support 32-bit operations).
markrad 0:cdf462088d13 452 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
markrad 0:cdf462088d13 453 * Removed test program o_p_test, the script compat.sh does more.
markrad 0:cdf462088d13 454 * Removed test program ssl_test, superseded by ssl-opt.sh.
markrad 0:cdf462088d13 455 * Removed helper script active-config.pl
markrad 0:cdf462088d13 456
markrad 0:cdf462088d13 457 New deprecations
markrad 0:cdf462088d13 458 * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
markrad 0:cdf462088d13 459 argument (allowing memory savings if HMAC is not used)
markrad 0:cdf462088d13 460
markrad 0:cdf462088d13 461 Semi-API changes (technically public, morally private)
markrad 0:cdf462088d13 462 * Renamed a few headers to include _internal in the name. Those headers are
markrad 0:cdf462088d13 463 not supposed to be included by users.
markrad 0:cdf462088d13 464 * Changed md_info_t into an opaque structure (use md_get_xxx() accessors).
markrad 0:cdf462088d13 465 * Changed pk_info_t into an opaque structure.
markrad 0:cdf462088d13 466 * Changed cipher_base_t into an opaque structure.
markrad 0:cdf462088d13 467 * Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and x509_crl.
markrad 0:cdf462088d13 468 * x509_crt.key_usage changed from unsigned char to unsigned int.

markrad 0:cdf462088d13 473 * The default minimum TLS version is now TLS 1.0.
markrad 0:cdf462088d13 474 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
markrad 0:cdf462088d13 475 default ciphersuite list returned by ssl_list_ciphersuites()
markrad 0:cdf462088d13 476 * Support for receiving SSLv2 ClientHello is now disabled by default at

markrad 0:cdf462088d13 479 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
markrad 0:cdf462088d13 480 enabled in the default configuration, this is only noticeable if using a
markrad 0:cdf462088d13 481 custom config.h
markrad 0:cdf462088d13 482 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

markrad 0:cdf462088d13 502 mbedtls_ssl_conf_transport()
markrad 0:cdf462088d13 503 mbedtls_ssl_conf_max_version()
markrad 0:cdf462088d13 504 mbedtls_ssl_conf_min_version()
markrad 0:cdf462088d13 505 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
markrad 0:cdf462088d13 506 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
markrad 0:cdf462088d13 507 an example implementation, see mbedtls_timing_delay_context and
markrad 0:cdf462088d13 508 mbedtls_timing_set/get_delay().
markrad 0:cdf462088d13 509 * With UDP sockets, it is no longer necessary to call net_bind() again
markrad 0:cdf462088d13 510 after a successful net_accept().
markrad 0:cdf462088d13 511
markrad 0:cdf462088d13 512 Changes
markrad 0:cdf462088d13 513 * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
markrad 0:cdf462088d13 514 thread-safe if MBEDTLS_THREADING_C is enabled.
markrad 0:cdf462088d13 515 * Reduced ROM fooprint of SHA-256 and added an option to reduce it even
markrad 0:cdf462088d13 516 more (at the expense of performance) MBEDTLS_SHA256_SMALLER.
markrad 0:cdf462088d13 517
markrad 0:cdf462088d13 518 = mbed TLS 1.3 branch
markrad 0:cdf462088d13 519

markrad 0:cdf462088d13 521 * With authmode set to SSL_VERIFY_OPTIONAL, verification of keyUsage and
markrad 0:cdf462088d13 522 extendedKeyUsage on the leaf certificate was lost (results not accessible
markrad 0:cdf462088d13 523 via ssl_get_verify_results()).
markrad 0:cdf462088d13 524 * Add countermeasure against "Lucky 13 strikes back" cache-based attack,

markrad 0:cdf462088d13 540 cross-compilation easier (thanks to Alon Bar-Lev).
markrad 0:cdf462088d13 541 * The benchmark program also prints heap usage for public-key primitives

markrad 0:cdf462088d13 600 * ssl_set_own_cert() no longer calls pk_check_pair() since the
markrad 0:cdf462088d13 601 performance impact was bad for some users (this was introduced in 1.3.10).
markrad 0:cdf462088d13 602 * Move from SHA-1 to SHA-256 in example programs using signatures
markrad 0:cdf462088d13 603 (suggested by Thorsten Mühlfelder).

markrad 0:cdf462088d13 640 for pre-1.2 clients when multiple certificates are available.
markrad 0:cdf462088d13 641 * Add support for getrandom() syscall on recent Linux kernels with Glibc or
markrad 0:cdf462088d13 642 a compatible enough libc (eg uClibc).

markrad 0:cdf462088d13 680 with a suitable (extended)KeyUsage or curve or no PSK set.
markrad 0:cdf462088d13 681 * It is now possible to disable negotiation of truncated HMAC server-side

markrad 0:cdf462088d13 691 * Remotely-triggerable memory leak when parsing some X.509 certificates
markrad 0:cdf462088d13 692 (server is not affected if it doesn't ask for a client certificate)
markrad 0:cdf462088d13 693 (found using Codenomicon Defensics).
markrad 0:cdf462088d13 694 * Remotely-triggerable memory leak when parsing crafted ClientHello

markrad 0:cdf462088d13 779 versions < TLS 1.1).
markrad 0:cdf462088d13 780 * Very large records using more than 224 bytes of padding were incorrectly
markrad 0:cdf462088d13 781 rejected with CBC-based ciphersuites and TLS >= 1.1
markrad 0:cdf462088d13 782 * Very large records using less padding could cause a buffer overread of up

markrad 0:cdf462088d13 790 * Use \n\t rather than semicolons for bn_mul asm, since some assemblers
markrad 0:cdf462088d13 791 interpret semicolons as comment delimiters (found by Barry K. Nathan).
