6 * Fix a vulnerability in TLS ciphersuites based on CBC and using SHA-384,
7 in (D)TLS 1.0 to 1.2, that allowed an active network attacker to
8 partially recover the plaintext of messages under some conditions by
9 exploiting timing measurements. With DTLS, the attacker could perform
10 this recovery by sending many messages in the same connection. With TLS
11 or if mbedtls_ssl_conf_dtls_badmac_limit() was used, the attack only
12 worked if the same secret (for example a HTTP Cookie) has been repeatedly
13 sent over connections manipulated by the attacker. Connections using GCM
14 or CCM instead of CBC, using hash sizes other than SHA-384, or using
15 Encrypt-then-Mac (RFC 7366) were not affected. The vulnerability was
16 caused by a miscalculation (for SHA-384) in a countermeasure to the
17 original Lucky 13 attack. Found by Kenny Paterson, Eyal Ronen and Adi
18 Shamir.
Manuel Pégourié-Gonnard69675d02018-06-28 12:10:27 +020019 * Fix a vulnerability in TLS ciphersuites based on CBC, in (D)TLS 1.0 to
20 1.2, that allowed a local attacker, able to execute code on the local
21 machine as well as manipulate network packets, to partially recover the
22 plaintext of messages under some conditions (see previous entry) by using
23 a cache attack targetting an internal MD/SHA buffer. Connections using
24 GCM or CCM instead of CBC or using Encrypt-then-Mac (RFC 7366) were not
25 affected. Found by Kenny Paterson, Eyal Ronen and Adi Shamir.
Manuel Pégourié-Gonnard99b6a712018-06-28 10:38:35 +020026 * Add a counter-measure against a vulnerability in TLS ciphersuites based
27 on CBC, in (D)TLS 1.0 to 1.2, that allowed a local attacker, able to
28 execute code on the local machine as well as manipulate network packets,
29 to partially recover the plaintext of messages under some conditions (see
30 previous entry) by using a cache attack targeting the SSL input record
31 buffer. Connections using GCM or CCM instead of CBC or using
32 Encrypt-then-Mac (RFC 7366) were not affected. Found by Kenny Paterson,
33 Eyal Ronen and Adi Shamir.

Gilles Peskine2347d4e2018-06-27 10:57:33 +020035Bugfix
Simon Butcher7350ab12018-05-23 17:55:02 +010036 * Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
Simon Butcher13188782018-05-11 16:41:07 +010037 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
38 configure the maximum length of a file path that can be buffered when
39 calling mbedtls_x509_crt_parse_path().
Moran Peker6981df52018-02-25 13:29:03 +020040 * Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by
41 TrinityTonic. #1359.

45Security
Simon Butcher50d80212018-04-30 17:23:10 +010046 * Fix an issue in the X.509 module which could lead to a buffer overread
47 during certificate validation. Additionally, the issue could also lead to
48 unnecessary callback checks being made or to some validation checks to be
49 omitted. The overread could be triggered remotely, while the other issues
50 would require a non DER-compliant certificate to be correctly signed by a
51 trusted CA, or a trusted CA with a non DER-compliant certificate. Found by
52 luocm. Fixes #825.
53 * Fix the buffer length assertion in the ssl_parse_certificate_request()
54 function which led to an arbitrary overread of the message buffer. The
55 overreads could be caused by receiving a malformed message at the point
56 where an optional signature algorithms list is expected when the signature
57 algorithms section is too short. In builds with debug output, the overread
58 data is output with the debug data.
Andrzej Kurek128bcbe2018-04-25 05:25:30 -040059 * Fix a client-side bug in the validation of the server's ciphersuite choice
Simon Butcher50d80212018-04-30 17:23:10 +010060 which could potentially lead to the client accepting a ciphersuite it didn't
61 offer or a ciphersuite that cannot be used with the TLS or DTLS version
62 chosen by the server. This could lead to corruption of internal data
63 structures for some configurations.
Gilles Peskine2a740612018-03-23 02:28:33 +010064
Gilles Peskined888bd22018-03-23 01:42:44 +010065Bugfix
66 * Add missing dependencies in test suites that led to build failures
67 in configurations that omit certain hashes or public-key algorithms.
68 Fixes #1040.
Gilles Peskinef362b972018-03-27 23:08:53 +020069 * Add missing dependencies for MBEDTLS_HAVE_TIME_DATE and
Simon Butcher50d80212018-04-30 17:23:10 +010070 MBEDTLS_VERSION_FEATURES in some test suites. Contributed by
71 Deomid Ryabkov. Fixes #1299, #1475.
72 * Fix the Makefile build process for building shared libraries on Mac OS X.
73 Fixed by mnacamura.
Jethro Beekman1a886ff2018-02-16 13:11:04 -080074 * Fix parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was
Simon Butcher50d80212018-04-30 17:23:10 +010075 unable to parse keys which had only the optional parameters field of the
76 ECPrivateKey structure. Found by Jethro Beekman, fixed in #1379.
77 * Return the plaintext data more quickly on unpadded CBC decryption, as
78 stated in the mbedtls_cipher_update() documentation. Contributed by
79 Andy Leiserson.
AndrzejKurek0de43062018-04-03 19:38:45 +020080 * Fix overriding and ignoring return values when parsing and writing to
81 a file in pk_sign program. Found by kevlut in #1142.
Krzysztof Stachowiak8fc134f2018-04-05 08:51:35 +020082 * Fix buffer length assertions in the ssl_parse_certificate_request()
83 function which leads to a potential one byte overread of the message
84 buffer.
Andrzej Kurekbb666142018-04-23 08:29:36 -040085 * Fix invalid buffer sizes passed to zlib during record compression and
86 decompression.
Gilles Peskined888bd22018-03-23 01:42:44 +010087
88Changes
89 * Improve testing in configurations that omit certain hashes or
90 public-key algorithms. Includes contributions by Gert van Dijk.
91 * Improve negative testing of X.509 parsing.
Andres Amaya Garcia2a0aee32018-03-21 15:35:01 +000092 * Do not define global mutexes around readdir() and gmtime() in
93 configurations where the feature is disabled. Found and fixed by Gergely
94 Budai.
Andres Amaya Garcia47569d72018-03-27 21:19:50 +010095 * Provide an empty implementation of mbedtls_pkcs5_pbes2() when
96 MBEDTLS_ASN1_PARSE_C is not enabled. This allows the use of PBKDF2
97 without PBES2. Fixed by Marcos Del Sol Vives.
Simon Butcher50d80212018-04-30 17:23:10 +010098 * Improve the documentation of mbedtls_net_accept(). Contributed by Ivan
99 Krylov.
Darryl Green093c1702018-03-29 16:05:44 +0100100 * Improve the documentation of mbedtls_ssl_write(). Suggested by
101 Paul Sokolovsky in #1356.
Simon Butcher50d80212018-04-30 17:23:10 +0100102 * Add an option in the Makefile to support ar utilities where the operation
Andres Amaya Garciabc006672018-03-27 19:14:24 +0100103 letter must not be prefixed by '-', such as LLVM. Found and fixed by
104 Alex Hixon.
Andres Amaya Garcia83bffd32018-03-26 00:15:21 +0100105 * Allow configuring the shared library extension by setting the DLEXT
Andres Amaya Garciabc006672018-03-27 19:14:24 +0100106 environment variable when using the project makefiles.
Gilles Peskine24f45842018-04-04 10:18:37 +0200107 * In the SSL module, when f_send, f_recv or f_recv_timeout report
108 transmitting more than the required length, return an error. Raised by
Jaeden Ameroee6c8222018-04-03 12:07:19 +0100109 Sam O'Connor in #1245.
Jaeden Ameroac9939c2018-04-03 18:27:18 +0100110 * Improve robustness of mbedtls_ssl_derive_keys against the use of
111 HMAC functions with non-HMAC ciphersuites. Independently contributed
112 by Jiayuan Chen in #1377. Fixes #1437.
Gilles Peskined888bd22018-03-23 01:42:44 +0100113

Manuel Pégourié-Gonnardf1985572018-03-06 10:34:56 +0100116Default behavior changes
117 * The truncated HMAC extension now conforms to RFC 6066. This means
118 that when both sides of a TLS connection negotiate the truncated
119 HMAC extension, Mbed TLS can now interoperate with other
120 compliant implementations, but this breaks interoperability with
121 prior versions of Mbed TLS. To restore the old behavior, enable
122 the (deprecated) option MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT in
123 config.h. Found by Andreas Walz (ivESK, Offenburg University of
124 Applied Sciences).

Gilles Peskinee9256c52018-02-22 16:17:52 +0100127 * Fix implementation of the truncated HMAC extension. The previous
128 implementation allowed an offline 2^80 brute force attack on the
129 HMAC key of a single, uninterrupted connection (with no
130 resumption of the session).
Hanno Beckerd43764f2017-11-06 15:10:38 +0000131 * Verify results of RSA private key operations to defend
132 against Bellcore glitch attack.
Jaeden Amero4e362952018-03-14 17:38:21 +0000133 * Fix a buffer overread in ssl_parse_server_key_exchange() that could cause
134 a crash on invalid input.
Jaeden Amero0980d9a2018-03-14 17:53:27 +0000135 * Fix a buffer overread in ssl_parse_server_psk_hint() that could cause a
136 crash on invalid input.
Manuel Pégourié-Gonnardb0661762018-03-13 11:53:30 +0100137 * Fix CRL parsing to reject CRLs containing unsupported critical
138 extensions. Found by Falko Strenzke and Evangelos Karatsiolis.
Hanno Beckerb09c5722017-11-20 10:43:35 +0000139
Antonio Quartullib9e3c6d2017-12-20 07:03:55 +0800140Features
141 * Extend PKCS#8 interface by introducing support for the entire SHA
142 algorithms family when encrypting private keys using PKCS#5 v2.0.
Gilles Peskinec0577f32018-02-14 11:33:30 +0100143 This allows reading encrypted PEM files produced by software that
144 uses PBKDF2-SHA2, such as OpenSSL 1.1. Submitted by Antonio Quartulli,
145 OpenVPN Inc. Fixes #1339
Simon Butcherbdf548e2018-02-05 01:11:05 +0000146
147Bugfix
148 * Fix assembly sequences in bn_mul.h and aesni.c to avoid segmentation
149 faults and errors when building for the 64-bit ILP32 ABI. Found and fixed
150 by James Cowgill.
151 * Fix test_suite_pk to work on 64-bit ILP32 systems. #849
152 * Fix mbedtls_x509_crt_profile_suiteb, which used to reject all certificates
153 with flag MBEDTLS_X509_BADCERT_BAD_PK even when the key type was correct.
Gilles Peskine7fded852018-02-27 08:37:52 +0100154 In the context of SSL, this resulted in handshake failure. Reported by
155 daniel in the Mbed TLS forum. #1351
Simon Butcherbdf548e2018-02-05 01:11:05 +0000156 * Fix Windows x64 builds with the included mbedTLS.sln file. #1347
Gilles Peskine9a00ef32018-03-11 00:52:24 +0100157 * Fix setting version TLSv1 as minimal version, even if TLS 1
158 is not enabled. Set MBEDTLS_SSL_MIN_MAJOR_VERSION
159 and MBEDTLS_SSL_MIN_MINOR_VERSION instead of
160 MBEDTLS_SSL_MAJOR_VERSION_3 and MBEDTLS_SSL_MINOR_VERSION_1. #664
Gilles Peskined3846462018-03-11 00:10:50 +0100161 * Fix compilation error on Mingw32 when _TRUNCATE is defined. Use _TRUNCATE
162 only if __MINGW32__ not defined. Fix suggested by Thomas Glanzmann and
163 Nick Wilson on issue #355
Gilles Peskine15967a82018-03-11 00:15:56 +0100164 * In test_suite_pk, pass valid parameters when testing for hash length
itayzafrircabc0982018-02-26 12:02:10 +0200165 overflow. #1179
Gilles Peskine8da4f862018-03-12 23:44:48 +0100166 * Fix memory allocation corner cases in memory_buffer_alloc.c module. Found
167 by Guido Vranken. #639
Jaeden Amero7f449632018-03-15 15:24:47 +0000168 * Log correct number of ciphersuites used in Client Hello message. #918
Gilles Peskine889de8e2018-03-12 23:51:01 +0100169 * Fix the entropy.c module to ensure that mbedtls_sha256_init() or
170 mbedtls_sha512_init() is called before operating on the relevant context
171 structure. Do not assume that zeroizing a context is a correct way to
172 reset it. Found independently by ccli8 on Github.
173 * In mbedtls_entropy_free(), properly free the message digest context.
Gilles Peskine8c121792018-03-13 17:26:49 +0100174 * Fix memory leak in RSA self test.
Gilles Peskinedf6f3dd2018-03-13 17:28:42 +0100175 * Fix X509 CRT parsing that would potentially accept an invalid tag when
176 parsing the subject alternative names.
Jaeden Amero4e362952018-03-14 17:38:21 +0000177 * Fix a possible arithmetic overflow in ssl_parse_server_key_exchange()
178 that could cause a key exchange to fail on valid data.
Jaeden Amero0980d9a2018-03-14 17:53:27 +0000179 * Fix a possible arithmetic overflow in ssl_parse_server_psk_hint() that
180 could cause a key exchange to fail on valid data.
Sanne Woudabfdcfba2017-09-05 17:00:54 +0100181 * Fix a 1-byte heap buffer overflow (read-only) during private key parsing.
182 Found through fuzz testing.

Simon Butcherbdf548e2018-02-05 01:11:05 +0000190 * Fix a heap corruption issue in the implementation of the truncated HMAC
191 extension. When the truncated HMAC extension is enabled and CBC is used,
192 sending a malicious application packet could be used to selectively corrupt
193 6 bytes on the peer's heap, which could potentially lead to crash or remote
194 code execution. The issue could be triggered remotely from either side in
195 both TLS and DTLS. CVE-2018-0488
196 * Fix a buffer overflow in RSA-PSS verification when the hash was too large
197 for the key size, which could potentially lead to crash or remote code
198 execution. Found by Seth Terashima, Qualcomm Product Security Initiative,
199 Qualcomm Technologies Inc. CVE-2018-0487
200 * Fix buffer overflow in RSA-PSS verification when the unmasked data is all
201 zeros.
202 * Fix an unsafe bounds check in ssl_parse_client_psk_identity() when adding
203 64 KiB to the address of the SSL buffer and causing a wrap around.
204 * Fix a potential heap buffer overflow in mbedtls_ssl_write(). When the (by
Hanno Beckerb658ee62017-09-18 16:07:19 +0100205 default enabled) maximum fragment length extension is disabled in the
206 config and the application data buffer passed to mbedtls_ssl_write
207 is larger than the internal message buffer (16384 bytes by default), the
208 latter overflows. The exploitability of this issue depends on whether the
209 application layer can be forced into sending such large packets. The issue
210 was independently reported by Tim Nordell via e-mail and by Florin Petriuc
Simon Butcherbdf548e2018-02-05 01:11:05 +0000211 and sjorsdewit on GitHub. Fix proposed by Florin Petriuc in #1022.
212 Fixes #707.
213 * Add a provision to prevent compiler optimizations breaking the time
214 constancy of mbedtls_ssl_safer_memcmp().
Andres Amaya Garcia55a52352017-07-05 15:40:17 +0100215 * Ensure that buffers are cleared after use if they contain sensitive data.
Andres Amaya Garcia11d2db12017-07-06 17:17:43 +0100216 Changes were introduced in multiple places in the library.
Ron Eldor4dc8af72017-09-05 15:34:35 +0300217 * Set PEM buffer to zero before freeing it, to avoid decoded private keys
218 being leaked to memory after release.
Janos Follathf3410832017-09-20 15:33:24 +0100219 * Fix dhm_check_range() failing to detect trivial subgroups and potentially
220 leaking 1 bit of the private key. Reported by prashantkspatil.
Simon Butcherbdf548e2018-02-05 01:11:05 +0000221 * Make mbedtls_mpi_read_binary() constant-time with respect to the input
222 data. Previously, trailing zero bytes were detected and omitted for the
223 sake of saving memory, but potentially leading to slight timing
224 differences. Reported by Marco Macchetti, Kudelski Group.
Hanno Becker25e39d32017-10-19 10:10:18 +0100225 * Wipe stack buffer temporarily holding EC private exponent
226 after keypair generation.
Simon Butcherbdf548e2018-02-05 01:11:05 +0000227 * Fix a potential heap buffer over-read in ALPN extension parsing
Manuel Pégourié-Gonnard022954f2018-01-09 10:43:43 +0100228 (server-side). Could result in application crash, but only if an ALPN
229 name larger than 16 bytes had been configured on the server.
Hanno Beckere27543d2017-10-13 16:54:58 +0100230 * Change default choice of DHE parameters from untrustworthy RFC 5114
231 to RFC 3526 containing parameters generated in a nothing-up-my-sleeve
232 manner.

235 * Allow comments in test data files.
Gilles Peskineedede442017-12-15 15:01:27 +0100236 * The selftest program can execute a subset of the tests based on command
237 line arguments.
Gilles Peskined3949622017-10-27 18:42:32 +0200238 * Improve the timing self-tests to be more robust when run on a
239 heavily-loaded machine.

Andres Amaya Garcia41a38df2017-07-05 13:27:17 +0100241Bugfix
Gilles Peskine9745cfd2017-10-19 17:46:14 +0200242 * Fix some invalid RSA-PSS signatures with keys of size 8N+1 that were
243 accepted. Generating these signatures required the private key.
Andres Amaya Garcia41a38df2017-07-05 13:27:17 +0100244 * Fix ssl_parse_record_header() to silently discard invalid DTLS records
245 as recommended in RFC 6347 Section 4.1.2.7.
Simon Butcher72e9ba22017-09-30 23:51:44 +0100246 * Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
247 Found by projectgus and jethrogb, #836.
Simon Butcher5d39ace2017-10-02 19:12:54 +0100248 * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
Ron Eldorbac9d4d2017-10-03 15:58:26 +0300249 * Parse signature algorithm extension when renegotiating. Previously,
250 renegotiated handshakes would only accept signatures using SHA-1
251 regardless of the peer's preferences, or fail if SHA-1 was disabled.
Andres Amaya Garciabc041132016-11-21 15:38:02 +0000252 * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
253 dates on leap years with 100 and 400 intervals are handled correctly. Found
254 by Nicholas Wilson. #694
Hanno Becker380aa642017-09-28 16:20:54 +0100255 * Fix out-of-memory problem when parsing 4096-bit PKCS8-encrypted RSA keys.
256 Found independently by Florian in the mbed TLS forum and by Mishamax.
257 #878, #1019.
Andres AG705cc652017-02-22 16:23:26 +0000258 * Fix unchecked return codes from AES, DES and 3DES functions in
259 pem_aes_decrypt(), pem_des_decrypt() and pem_des3_decrypt() respectively.
260 If a call to one of the functions of the cryptographic primitive modules
261 failed, the error may not be noticed by the function
262 mbedtls_pem_read_buffer() causing it to return invalid values. Found by
263 Guido Vranken. #756

Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200729Features
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200730 * Support for DTLS 1.0 and 1.2 (RFC 6347).
731 * Ability to override core functions from MDx, SHAx, AES and DES modules
732 with custom implementation (eg hardware accelerated), complementing the
733 ability to override the whole module.
734 * New server-side implementation of session tickets that rotate keys to
735 preserve forward secrecy, and allows sharing across multiple contexts.
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200736 * Added a concept of X.509 cerificate verification profile that controls
737 which algorithms and key sizes (curves for ECDSA) are acceptable.
738 * Expanded configurability of security parameters in the SSL module with
739 mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
740 * Introduced a concept of presets for SSL security-relevant configuration
741 parameters.

Manuel Pégourié-Gonnarda25ffc32015-06-25 12:01:16 +0200744 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
745 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200746 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100747 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200748 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100749 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200750 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200751 mbedtls_cipher_info_t.key_length -> key_bitlen
752 mbedtls_cipher_context_t.key_length -> key_bitlen
753 mbedtls_ecp_curve_info.size -> bit_size
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200754 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200755 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200756 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200757 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200758 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200759 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200761 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
762 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Tillmann Karras588ad502015-09-25 04:27:22 +0200763 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200764 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100765 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),

773 implementations (SNI, PSK) instead of their *conf counterparts:
774 mbedtls_ssl_set_hs_own_cert()
775 mbedtls_ssl_set_hs_ca_chain()
776 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200777 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100778 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200779 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100780 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200781 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
782 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200783 * The SSL debug callback gained two new arguments (file name, line number).
784 * Debug modes were removed.
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200785 * mbedtls_ssl_conf_truncated_hmac() now returns void.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100786 * mbedtls_memory_buffer_alloc_init() now returns void.
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200787 * X.509 verification flags are now an uint32_t. Affect the signature of:

789 mbedtls_x509_ctr_verify_info()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100790 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200791 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100792 * The following functions changed prototype to avoid an in-out length
793 parameter:
794 mbedtls_base64_encode()
795 mbedtls_base64_decode()
796 mbedtls_mpi_write_string()
797 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200798 * In the NET module, all "int" and "int *" arguments for file descriptors

807 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100808 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
809 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
810 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100811 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200812 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
813 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
814 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000815 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200816 * calloc() is now used instead of malloc() everywhere. API of platform

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200871 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
872 enabled in the default configuration, this is only noticeable if using a
873 custom config.h
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100874 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.

894 mbedtls_ssl_conf_transport()
895 mbedtls_ssl_conf_max_version()
896 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0c890352015-05-13 10:28:41 +0200897 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
898 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
899 an example implementation, see mbedtls_timing_delay_context and
900 mbedtls_timing_set/get_delay().
