Hi everybody,

I ran again into problems with the supplemental data messages. I tried to copy 
a certificate into the buffer of type gnutls_buffer and do not manage to send 
all 1314 bytes of the certificate. Instead it sends only 41 bytes. I tried it 
with another certificate which resulted in 65 bytes sent. This is pretty 
strange. I expected the buffer to stop at a \0 character in the signature, but 
that does not seem to be the case since strlen of the original data results in 
the correct length of 1314. Any ideas?

In order to simplify debugging, I copied my gnutls version including the 
tls-tpm extension (not finished yet, but does not cause crashes :-)) onto a 
server:
http://diuf.unifr.ch/people/latzec/gnutls-CL-28052010.tar.gz

Furthermore, I uploaded my little sample program as well:
http://diuf.unifr.ch/people/latzec/sample.tar.gz

I would be happy for any hints or ideas since I am clueless at the moment.
Could you use debugging output with
   gnutls_global_set_log_function (tls_log_func);
   gnutls_global_set_log_level (level);
?

Oh sorry, I did that already (with level 3), but forgot to add the file. You find it here:

http://diuf.unifr.ch/people/latzec/out

Thats the output of the client who is supposed to send the supplemental data.

Level 2 should be sufficient.

regards,
Nikos
