Removed further timing differences during SSL message decryption in ssl_decrypt_buf()
...
New padding checking is unbiased on correct or incorrect padding and
has no branch prediction timing differences.
The additional MAC checks further straighten out the timing differences.

Fixed memory leak in ssl_free() and ssl_reset() for active session
2013-02-14 11:19:38 +01:00
40865c8e5d
Added sending of alert messages in case of decryption failures as per RFC
...
The flag POLARSSL_SSL_ALERT_MESSAGES switched between enabling and
disabling the sending of alert messages that give adversaries intel
about the result of their action. PolarSSL can still communicate with
other parties if they are disabled, but debugging of issues might be
harder.
2013-02-02 19:04:13 +01:00
d66f070d49
Disable debug messages that can introduce a timing side channel.
...
Introduced the POLARSSL_SSL_DEBUG_ALL flag to enable all these debug
messages in case somebody does want to see the reason checks fail.

Fixed timing difference resulting from badly formatted padding.
2013-02-02 19:04:13 +01:00

Added ssl_handshake_step() to allow single stepping the handshake
...
process
Single stepping the handshake process allows for better support of
non-blocking network stacks and for getting information from specific
handshake messages if wanted.

2012-02-06 16:45:10 +00:00
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
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
2011-12-10 21:55:01 +00:00
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

2011-06-08 13:10:54 +00:00
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.
