daa3e7c7f8 tsg: fix possible free of initialized memory 2014-11-27 15:08:07 +01:00

5066a5e455 tsg: rpc_send_enqueue_pdu always free buffer 
rpc_send_enqueue_pdu returns -1 on error but the type of error isn't
distinguishable. Therefore make sure that the buffer gets always freed.
The only exception to this is when the pdu was already queued. Then the
dequeuing function should take care of freeing the buffer when
processing the pdu.

c0525574c8 transport: handle all return values of tsg_read 
tsg_read can also return 0 which means that no data (complete PDU) is
currently available. This case wasn't handled properly.

Fixes #2056

81a6c43938 tsg: fix segfault 
Revert false positive from commit 585d9101b7
buffer shouldn't be freed since it is set and used in a stream.

dd6d829550 Allow transport_write calls to be non-blocking 
This big patch allows to have non-blocking writes. To achieve
this, it slightly changes the way transport is handled. The misc transport
layers are handled with OpenSSL BIOs. In the chain we insert a
bufferedBIO that will bufferize write calls that couldn't be honored.

For an access with Tls security the BIO chain would look like this:
  FreeRdp Code ===> SSL bio ===> buffered BIO ===> socket BIO

The buffered BIO will store bytes that couldn't be send because of
blocking write calls.

This patch also rework TSG so that it would look like this in the
case of SSL security with TSG:
                                         (TSG in)
                              > SSL BIO => buffered BIO ==> socket BIO
                             /
FreeRdp => SSL BIO => TSG BIO
                             \
                              > SSL BIO => buffered BIO ==> socket BIO
                                        (TSG out)

So from the FreeRDP point of view sending something is only BIO_writing
on the frontBio (last BIO on the left).

9f1d0201ec Changes for base64 
This patch changes the prototype for decode_base64 so that the encode / decode
method are consistant (encode(BYTE *) => char* and decode(char*) => BYTE*).
It also does some improvements with unrolling loops so that end conditions are
tested only at the end.
The patch also adds some unitary tests.
Before the patch base64_decode() made valgrind complain about uninitialized
bits, after valgrind is happy and very quiet.
