Paul Bakkera35aa542013-03-06 17:06:21 +0100551 encountering a parse-error. Beware that the meaning of return values has
552 changed!

587 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +0100588 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +0000589 * Functions requiring File System functions can now be disabled
590 by undefining POLARSSL_FS_IO

598 * Major argument / variable rewrite. Introduced use of size_t
599 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100600 better unsigned / signed use. Renamed internal bigint types
601 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000602 * mpi_init() and mpi_free() now only accept a single MPI
603 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000604 * The error codes have been remapped and combining error codes
605 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100606 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000607 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
608 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100609 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
610 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
611 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
612 after the handshake.

854XySSL ChangeLog
855
856= Version 0.9 released on 2008-03-16
857
858 * Added support for ciphersuite: SSL_RSA_AES_128_SHA
859 * Enabled support for large files by default in aescrypt2.c
860 * Preliminary openssl wrapper contributed by David Barrett
861 * Fixed a bug in ssl_write() that caused the same payload to
862 be sent twice in non-blocking mode when send returns EAGAIN
863 * Fixed ssl_parse_client_hello(): session id and challenge must
864 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
865 * Added user-defined callback debug function (Krystian Kolodziej)
866 * Before freeing a certificate, properly zero out all cert. data
867 * Fixed the "mode" parameter so that encryption/decryption are
868 not swapped on PadLock; also fixed compilation on older versions
869 of gcc (bug reported by David Barrett)
870 * Correctly handle the case in padlock_xcryptcbc() when input or
871 ouput data is non-aligned by falling back to the software
872 implementation, as VIA Nehemiah cannot handle non-aligned buffers
873 * Fixed a memory leak in x509parse_crt() which was reported by Greg
874 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to
875 Matthew Page who reported several bugs
876 * Fixed x509_get_ext() to accept some rare certificates which have
877 an INTEGER instead of a BOOLEAN for BasicConstraints::cA.

879 (patch contributed by David Patino)
880 * Make x509parse_verify() return BADCERT_CN_MISMATCH when an empty
881 string is passed as the CN (bug reported by spoofy)
882 * Added an option to enable/disable the BN assembly code
883 * Updated rsa_check_privkey() to verify that (D*E) = 1 % (P-1)*(Q-1)
884 * Disabled obsolete hash functions by default (MD2, MD4); updated
885 selftest and benchmark to not test ciphers that have been disabled
886 * Updated x509parse_cert_info() to correctly display byte 0 of the
887 serial number, setup correct server port in the ssl client example
888 * Fixed a critical denial-of-service with X.509 cert. verification:
889 peer may cause xyssl to loop indefinitely by sending a certificate
890 for which the RSA signature check fails (bug reported by Benoit)
891 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
892 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
893 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
894 * Modified ssl_parse_client_key_exchange() to protect against
895 Daniel Bleichenbacher attack on PKCS#1 v1.5 padding, as well
896 as the Klima-Pokorny-Rosa extension of Bleichenbacher's attack
897 * Updated rsa_gen_key() so that ctx->N is always nbits in size
898 * Fixed assembly PPC compilation errors on Mac OS X, thanks to
899 David Barrett and Dusan Semen
