The inet6_lookup family of functions requires a net to lookup
a socket in, so give a proper one to them.

No more things to do for dccpv6, since routing is OK and the
ipv4-like transport layer filtering is not done for ipv6.

This call uses the sock to get the net to lookup the routing
in. With CONFIG_NET_NS this code will OOPS, since the sk ptr
is NULL.

After looking inside the ip6_dst_lookup and drawing the analogy
with respective ipv6 code, it seems, that the dccp ctl socket 
is a good candidate for the first argument.

The xfrm_get_policy() and xfrm_add_pol_expire() put some rather large structs
on the stack to work around the LSM API.  This patch attempts to fix that
problem by changing the LSM API to require only the relevant "security"
pointers instead of the entire SPD entry; we do this for all of the
security_xfrm_policy*() functions to keep things consistent.

Recently I posted a patch to add some informational items to
/proc/net/sctp/assocs.  All the information is correct, but because
of how the seqfile show operation is laid out, some of the formatting
is backwards.  This patch corrects that formatting, so that the new

This patch fixes a difference between IPv4 and IPv6 when sending packets
to the unspecified address (either 0.0.0.0 or ::) when using raw or
un-connected UDP sockets.  There are two cases where IPv6 either fails
to send anything, or sends with the destination address set to ::.  For
example:

--> ping -c1 0.0.0.0
PING 0.0.0.0 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.032 ms

--> ping6 -c1 ::
PING ::(::) 56 data bytes
ping: sendmsg: Invalid argument

Doing a sendto("0.0.0.0") reveals:

10:55:01.495090 IP localhost.32780 > localhost.7639: UDP, length 100

Doing a sendto("::") reveals:

10:56:13.262478 IP6 fe80::217:8ff:fe7d:4718.32779 > ::.7639: UDP, length 100

If you issue a connect() first in the UDP case, it will be sent to ::1,
similar to what happens with TCP.

This restores the BSD-ism.

- This patch adjusts IPv6 multicast routing module, net/ipv6/ip6mr.c,
to use mroute6 header definitions instead of mroute.
 (MFC6_LINES instead of MFC_LINES, MAXMIFS instead of MAXVIFS, mifi_t
instead of vifi_t.)

- In addition, inclusion of some headers was removed as it is not needed.
