502bf30fb5 Handle reassembly of handshake messages
Works only with GnuTLS for now, OpenSSL packs other records in the same
datagram after the last fragmented one, which we don't handle yet.

Also, ssl-opt.sh fails the tests with valgrind for now: we're so slow with
valgrind that gnutls-serv retransmits some messages, and we don't handle
duplicated messages yet.

956c9e063d Reduced the input / output overhead with 200+ bytes and covered corner
case

The actual input / output buffer overhead is only 301 instead of 512.
This requires a proper check on the padding_idx to prevent out of bounds
reads.

Previously a remote party could potentially trigger an access error and
thus stop the application when sending a malicious packet having
MAX_CONTENT_LEN of data, 32 bytes of MAC and a decrypted padlen of .
This would result in reading from in_ctr + 13 + 32 + MAX_CONTENT_LEN - 1 - 1
for 256 bytes (including fake padding check). Or 13 + 32 bytes over the
buffer length.

We now reset padding_idx to 0, if it's clear that it will never be a
valid padding (padlen > msg_len || msg_len + padlen + 256 > buffer_len)

8f4ddaeea9 Ability to specify allowed ciphersuites based on the protocol version.
The ciphersuites parameter in the ssl_session structure changed from

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

b15b851d6d - Check for failed malloc() in ssl_set_hostname() and x509_get_entries() (Closes ticket #47, found by Hugo Leisink) 2012-01-13 13:44:06 +00:00
Paul Bakker
69e095cc15 - Changed the behaviour of x509parse_parse_crt for permissive parsing. Now returns the number of 'failed certificates' instead of having a switch to enable it.
- As a consequence all error code that were positive were changed. A lot of MALLOC_FAILED and FILE_IO_ERROR error codes added for different modules.
 - Programs and tests were adapted accordingly

6c0ceb3f9a - Added permissive certificate parsing to x509parse_crt() and x509parse_crtfile(). With permissive parsing the parsing does not stop on encountering a parse-error 2011-12-04 12:24:18 +00:00

a3d195c41f - Changed the used random function pointer to more flexible format. Renamed havege_rand() to havege_random() to prevent mistakes. Lots of changes as a consequence in library code and programs 2011-11-27 21:07:34 +00:00

Paul Bakker
831a755d9e - Changed behaviour of net_recv(), ssl_fetch_input() and ssl_read(). net_recv() now returns 0 on EOF instead of POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function. ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received after the handshake.
- Network functions now return POLARSSL_ERR_NET_WANT_READ or POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous POLARSSL_ERR_NET_TRY_AGAIN
2011-05-18 13:32:51 +00:00

9d781407bc - A error_strerror function() has been added to translate between error codes and their description.
- The error codes have been remapped and combining error codes is now done with a PLUS instead of an OR as error codes used are negative.
 - Descriptions to all error codes have been added.
 - Generation script for error.c has been created to automatically generate error.c from the available error definitions in the headers.
