[Xen-devel] Re: [PATCH][Take 2] VNC authentification

[Anthony Liguori <aliguori@xxxxxxxxxx>]

A couple comments:

Does this code actually work?  You call vnc_read_when twice in the same 
function.  The first one should never get called (it can only be called 
from the main loop and there can only ever be one outstanding read 
function).
There are a couple weird bits in the code too that I cannot reply to 
(your mailer is sending the attachment as a octet-stream, please inline 
too next time you send the patch).
Otherwise, it looks really promising!

Regards,

Anthony Liguori
