[jra at samba.org]

Author: jra
Date: 2004-11-18 22:45:58 +0000 (Thu, 18 Nov 2004)
New Revision: 3866

WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=3866

Log:
Fix from david.hu at hp.com - make a copy of an incoming message
rather than indirecting into it as a struct (may not be on an
even byte boundary). Bug #2052.
WARNING ! This code is different from 3.0.x. Someone needs to
look at this (Jerry?).
