986 entropy sources
Paul Bakker7eb013f2011-10-06 12:37:39 +0000987
Paul Bakkerca6f3e22011-10-06 13:11:08 +0000988Changes

Paul Bakkera35aa542013-03-06 17:06:21 +01001011 encountering a parse-error. Beware that the meaning of return values has
1012 changed!

Paul Bakker335db3f2011-04-25 15:28:35 +00001049 * Functions requiring File System functions can now be disabled
1050 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001051 * A error_strerror function() has been added to translate between

1058 * Major argument / variable rewrite. Introduced use of size_t
1059 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001060 better unsigned / signed use. Renamed internal bigint types
1061 t_int and t_dbl to t_uint and t_udbl in the process

1065 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001066 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001067 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1068 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001069 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1070 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1071 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1072 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001073 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

1090 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001091 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001092

1321 * Fixed a bug in ssl_write() that caused the same payload to
1322 be sent twice in non-blocking mode when send returns EAGAIN
1323 * Fixed ssl_parse_client_hello(): session id and challenge must
1324 not be swapped in the SSLv2 ClientHello (found by Greg Robson)
1325 * Added user-defined callback debug function (Krystian Kolodziej)
1326 * Before freeing a certificate, properly zero out all cert. data

1328 not swapped on PadLock; also fixed compilation on older versions
1329 of gcc (bug reported by David Barrett)
1330 * Correctly handle the case in padlock_xcryptcbc() when input or
1331 ouput data is non-aligned by falling back to the software
1332 implementation, as VIA Nehemiah cannot handle non-aligned buffers
1333 * Fixed a memory leak in x509parse_crt() which was reported by Greg
1334 Robson-Garth; some x509write.c fixes by Pascal Vizeli, thanks to

1345 selftest and benchmark to not test ciphers that have been disabled
1346 * Updated x509parse_cert_info() to correctly display byte 0 of the
1347 serial number, setup correct server port in the ssl client example
1348 * Fixed a critical denial-of-service with X.509 cert. verification:
1349 peer may cause xyssl to loop indefinitely by sending a certificate
1350 for which the RSA signature check fails (bug reported by Benoit)
1351 * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
1352 HMAC-MD5, HMAC-SHA1, HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512
1353 * Fixed HMAC-SHA-384 and HMAC-SHA-512 (thanks to Josh Sinykin)
1354 * Modified ssl_parse_client_key_exchange() to protect against
