Subject: skb_ip_make_writable and skbs not owned by a socket
Date: Sun, 02 Jan 2005 22:19:45 +0100	[thread overview]
Message-ID: <41D86571.6070501@trash.net> (raw)

Hi,

skb_ip_make_writable copies the packet as soon as the data area needs
to be touched. This is of course necessary for packets generated locally,
but can't we mangle the data area of skbs with skb->sk == NULL without
copying them ?

Regards
Patrick
