Subject: PR/33162 CVS commit: src/sys/netipsec
Date: Fri, 28 Apr 2006 22:39:02 +0000 (UTC)

 Module Name:	src
 Committed By:	pavel
 Date:		Fri Apr 28 22:39:02 UTC 2006
 
 Modified Files:
 	src/sys/netipsec: xform_esp.c
 
 Log Message:
 The esp_input_cb function used m_copyback, which fails if the mbuf is
 read-only. This can actually happen if the packet was received by the
 xennet interface, see PR kern/33162. Change it to m_copyback_cow.
 
 AH and IPCOMP probably need similar fixes.
 
 Requested by Jeff Rizzo, tested on Xen with -current by him.
