Paul Bakker6c0ceb32011-12-04 12:24:18 +0000342 * Added permissive certificate parsing to x509parse_crt() and
343 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +0100344 encountering a parse-error. Beware that the meaning of return values has
345 changed!
Paul Bakker69e095c2011-12-10 21:55:01 +0000346 * All error codes are now negative. Even on mermory failures and IO errors.

391 * Major argument / variable rewrite. Introduced use of size_t
392 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100393 better unsigned / signed use. Renamed internal bigint types
394 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000395 * mpi_init() and mpi_free() now only accept a single MPI
396 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000397 * The error codes have been remapped and combining error codes
398 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100399 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000400 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
401 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +0100402 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
403 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
404 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
405 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000406 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

Paul Bakker98675492011-03-26 13:17:12 +0000422 * x509parse_key() (and as a consequence x509parse_keyfile())
423 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +0100424 before parsing a key or keyfile!

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

682 peer may cause xyssl to loop indefinitely by sending a certificate
683 for which the RSA signature check fails (bug reported by Benoit)
