4Features
5 * Added ssl_session_reset() to allow better multi-connection pools of
6 SSL contexts without needing to set all non-connection-specific
7 data and pointers again. Adapted ssl_server to use this functionality.
Paul Bakker490ecc82011-10-06 13:04:09 +00008 * Added ssl_set_max_version() to allow clients to offer a lower maximum
9 supported version to a server to help buggy server implementations.
10 (Closes ticket #36)

32 trade-off

84 * Major argument / variable rewrite. Introduced use of size_t
85 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +000086 better unsigned / signed use. Renamed internal bigint types
87 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +000088 * mpi_init() and mpi_free() now only accept a single MPI
89 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +000090 * The error codes have been remapped and combining error codes
91 is now done with a PLUS instead of an OR as error codes
92 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +000093 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
94 net_recv() now returns 0 on EOF instead of
95 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
96 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.

98 after the handshake.

100 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
101 POLARSSL_ERR_NET_TRY_AGAIN

348 be sent twice in non-blocking mode when send returns EAGAIN
349 * Fixed ssl_parse_client_hello(): session id and challenge must
350 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
351 * Added user-defined callback debug function (Krystian Kolodziej)
352 * Before freeing a certificate, properly zero out all cert. data

355 of gcc (bug reported by David Barrett)
356 * Correctly handle the case in padlock_xcryptcbc() when input or
357 ouput data is non-aligned by falling back to the software
358 implementation, as VIA Nehemiah cannot handle non-aligned buffers

360 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to
361 Matthew Page who reported several bugs

365 (patch contributed by David Patino)

371 selftest and benchmark to not test ciphers that have been disabled
372 * Updated x509parse_cert_info() to correctly display byte 0 of the
373 serial number, setup correct server port in the ssl client example

375 peer may cause xyssl to loop indefinitely by sending a certificate
376 for which the RSA signature check fails (bug reported by Benoit)
377 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
378 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
379 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
380 * Modified ssl_parse_client_key_exchange() to protect against
381 Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well
382 as the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
383 * Updated rsa_gen_key() so that ctx->N is always nbits in size
