Subject: Set msg_type when decoding FAST requests
X-Git-Tag: krb5-1.10.6-final~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=219be8f8cd48325df2b240876aa90bab03a036c9;p=thirdparty%2Fkrb5.git

Set msg_type when decoding FAST requests

An RFC 6113 KrbFastReq contains a padata sequence and a KDC-REQ-BODY,
neither of which contain the msg-type field found in a KDC-REQ.  So
when we decode the FAST request, the resulting krb5_kdc_req structure
has a msg_type of 0.  Copy msg_type from the outer body, since we make
use of it in further KDC processing.
