Revision a520723f29aac6598ff0d69e34f5e9b88213e511 authored by Matt Caswell on 14 October 2016, 12:07:00 UTC, committed by Matt Caswell on 28 October 2016, 08:43:41 UTC
The previous commit inspired a review of all the length checks for the extension adding code. This adds more robust checks and adds checks where some were missing previously. The real solution for this is to use WPACKET which is currently in master - but that cannot be applied to release branches. Reviewed-by: Rich Salz <rsalz@openssl.org>

=head1 NAME
DH_size - get Diffie-Hellman prime size
=head1 SYNOPSIS
#include <openssl/dh.h>
int DH_size(DH *dh);
=head1 DESCRIPTION
This function returns the Diffie-Hellman size in bytes. It can be used
to determine how much memory must be allocated for the shared secret
computed by DH_compute_key().
B<dh-E<gt>p> must not be B<NULL>.
=head1 RETURN VALUE
The size in bytes.
=head1 SEE ALSO
