Here's an updated version of the patch:
[snipped]
This doesn't compile cleanly, patches should compile without any
warnings.
In this case there are warnings about an implicit declaration of
dtls1_listen(). Just adding a prototype ssl_locl.h is not sufficient
because it needs the definition of struct sockaddr too.
Sorry, I only compiled it on Mac OS X and it works there. Compiling on
FreeBSD 8.0 helped to reproduce the warnings, so here is a new
version. Actually, dtls1_listen() doesn't need to be defined in
ssl_locl.h because it's only used inside d1_lib.c and nowhere else. It
was implicit because its declaration was after it is called in
dtls1_ctrl(), so adding a declaration at the top of the file solves
the problem and there are no warnings left. If you still get warnings
for a missing declaration of struct sockaddr, please try to add
"include <sys/socket.h>".
On some platforms you need to include sys/types.h before including
sys/socket.h
Best regards
Michael
