Subject: Restore the dns_message_reset() call before the dns_dispatch_getnext()
X-Git-Tag: v9.17.6~6^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1f63bb15b3ce0984ecf1971c2736477e5c3ac67f;p=thirdparty%2Fbind9.git

Restore the dns_message_reset() call before the dns_dispatch_getnext()

This was accidentally lost in the process of moving rmessage from fctx
to query.  Without this dns_message_setclass() will fail.
