Subject: dtls client hello: fix zeroed random (fixes #960)
X-Git-Tag: 3.6.13~6^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c01011c2d8533dbbbe754e49e256c109cb848d0d;p=thirdparty%2Fgnutls.git

dtls client hello: fix zeroed random (fixes #960)

This broke with bcf4de03 "handshake: treat reply to HRR as a reply to
hello verify request", which failed to "De Morgan" properly.
