It does not make sense to queue retransmitted packets if the
original packet is still in some queue of this host. So add
a check to xdst_queue_output() and drop the packet if the
original packet is not yet sent.

There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

__xfrm4/6_state_addr_check is a four steps check, all we need to do
is checking whether the destination address match when looking SA
using wildcard source address. Passing saddr from flow is worst option,
as the checking needs to reach the fourth step while actually only
one time checking will do the work.
So, simplify this process by only checking destination address when
using wildcard source address for looking up SAs.

Conflicts:
include/net/xfrm.h
Simple conflict between Joe Perches "extern" removal for function
declarations in header files and the changes in Steffen's tree.
Steffen Klassert says:
====================
Two patches that are left from the last development cycle.
Manual merging of include/net/xfrm.h is needed. The conflict
can be solved as it is currently done in linux-next.
1) We announce the creation of temporary acquire state via an asyc event,
so the deletion should be annunced too. From Nicolas Dichtel.
2) The VTI tunnels do not real tunning, they just provide a routable
IPsec tunnel interface. So introduce and use xfrm_tunnel_notifier
instead of xfrm_tunnel for xfrm tunnel mode callback. From Fan Du.
====================

If asynchronous events are enabled for a particular netlink socket,
the notify function is called by the advance function. The notify
function creates and dispatches a km_event if a replay timeout occurred,
or at least replay_maxdiff packets have been received since the last
asynchronous event has been sent. The function is supposed to return if
neither of the two events were detected for a state, or replay_maxdiff
is equal to zero.
Replay_maxdiff is initialized in xfrm_state_construct to the value of
the xfrm.sysctl_aevent_rseqth (2 by default), and updated if for a state
if the netlink attribute XFRMA_REPLAY_THRESH is set.
If, however, replay_maxdiff is set to zero, then all of the three notify
implementations perform a break from the switch statement instead of
checking whether a timeout occurred, and -- if not -- return. As a
result an asynchronous event is generated for every replay update of a
state that has a zero replay_maxdiff value.
This patch modifies the notify functions such that they immediately
return if replay_maxdiff has the value zero, unless a timeout occurred.

We pass the wrong netlink attribute to xfrm_replay_verify_len().
It should be XFRMA_REPLAY_ESN_VAL and not XFRMA_REPLAY_VAL as
we currently doing. This causes memory corruptions if the

the right attribute to xfrm_replay_verify_len().

The conflicts were minor:
1) sit.c changes overlap with change to ip_tunnel_xmit() signature.
2) br_multicast.c had an overlap between computing max_delay using
msecs_to_jiffies and turning MLDV2_MRC() into an inline function
with a name using lowercase instead of uppercase letters.
3) stmmac had two overlapping changes, one which conditionally allocated

which should not go into the new of_find_property() basic block.

The net_device might be not set on the skb when we try refcounting.
This leads to a null pointer dereference in xdst_queue_output().
It turned out that the refcount to the net_device is not needed
after all. The dst_entry has a refcount to the net_device before
we queue the skb, so it can't go away. Therefore we can remove the
refcount on queueing to fix the null pointer dereference.

We need to choose the protocol family by skb->protocol. Otherwise we

In xfrm4 and xfrm6 we need to take care about sockets of the other
address family. This could happen because a 6in4 or 4in6 tunnel could
get protected by ipsec.
Because we don't want to have a run-time dependency on ipv6 when only
using ipv4 xfrm we have to embed a pointer to the correct local_error
function in xfrm_state_afinet and look it up when returning an error
depending on the socket address family.

Current net name space has only one genid for both IPv4 and IPv6, it has below
drawbacks:
- Add/delete an IPv4 address will invalidate all IPv6 routing table entries.
- Insert/remove XFRM policy will also invalidate both IPv4/IPv6 routing table
entries even when the policy is only applied for one address family.
Thus, this patch attempt to split one genid for two to cater for IPv4 and IPv6

then the received packet will be dropped after adding

because xfrm policy direction has same value with corresponding
flow direction, so this problem is covered.
In xfrm_lookup and __xfrm_policy_check, flow_cache_lookup is used to
accelerate the lookup.
Flow direction is given to flow_cache_lookup by policy_to_flow_dir.
When the flow cache is mismatched, callback 'resolver' is called.
'resolver' requires xfrm direction,
so convert direction back to xfrm direction.

By default, DSCP is copying during encapsulation.
Copying the DSCP in IPsec tunneling may be a bit dangerous because packets with
different DSCP may get reordered relative to each other in the network and then
dropped by the remote IPsec GW if the reordering becomes too big compared to the
replay window.
It is possible to avoid this copy with netfilter rules, but it's very convenient
to be able to configure it for each SA directly.
This patch adds a toogle for this purpose. By default, it's not set to maintain
backward compatibility.

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.

this patch use remove_proc_entry to replace proc_net_remove.
we can remove proc_net_remove after this patch.

Right now, some modules such as bonding use proc_create
to create proc entries under /proc/net/, and other modules
such as ipv4 use proc_net_fops_create.
It looks a little chaos.this patch changes all of
proc_net_fops_create to proc_create. we can remove
proc_net_fops_create after this patch.

Steffen Klassert says:
====================
1) Remove a duplicated call to skb_orphan() in pf_key, from Cong Wang.
2) Prepare xfrm and pf_key for algorithms without pf_key support,
from Jussi Kivilinna.
3) Fix an unbalanced lock in xfrm_output_one(), from Li RongQing.
4) Add an IPsec state resolution packet queue to handle
packets that are send before the states are resolved.
5) xfrm4_policy_fini() is unused since 2.6.11, time to remove it.
From Michal Kubecek.
6) The xfrm gc threshold was configurable just in the initial
namespace, make it configurable in all namespaces. From
Michal Kubecek.
7) We currently can not insert policies with mark and mask
such that some flows would be matched from both policies.
Allow this if the priorities of these policies are different,
the one with the higher priority is used in this case.

We currently can not insert policies with mark and mask
such that some flows would be matched from both policies.
We make this possible when the priority of these policies
are different. If both policies match a flow, the one with
the higher priority is used.

As the default, we blackhole packets until the key manager resolves
the states. This patch implements a packet queue where IPsec packets
are queued until the states are resolved. We generate a dummy xfrm
bundle, the output routine of the returned route enqueues the packet
to a per policy queue and arms a timer that checks for state resolution
when dst_output() is called. Once the states are resolved, the packets
are sent out of the queue. If the states are not resolved after some
time, the queue is flushed.
This patch keeps the defaut behaviour to blackhole packets as long
as we have no states. To enable the packet queue the sysctl
xfrm_larval_drop must be switched off.

All users of xfrm_addr_cmp() use its result as boolean.
Introduce xfrm_addr_equal() (which is equal to !xfrm_addr_cmp())
and convert all users.
