This will get us closer to being able to do "neigh stuff"
completely independent of the underlying dst_entry for
protocols (ipv4/ipv6) that wish to do so.We will also be able to make dst entries neigh-less.

there is only one user of vlan_find_dev outside of the actual vlan code:
qlcnic uses it to iterate over some VLANs it knows.let's just make vlan_find_dev private to the VLAN code and have the
iteration in qlcnic be a bit more direct. (a few rcu dereferences less
too)Signed-off-by: David Lamparter

It's just taking on one of two possible values, either
neigh_ops->output or dev_queue_xmit(). And this is purely depending

Now that hh_cache entries are embedded inside of neighbour
entries, their lifetimes and accesses are now synchronous
to that of the encompassing neighbour object.Therefore we don't need to hook up the blackhole op to
hh_output on destroy.Signed-off-by: David S. Miller

Now that there is a one-to-one correspondance between neighbour
and hh_cache entries, we no longer need:1) dynamic allocation
2) attachment to dst->hh
3) refcountingInitialization of the hh_cache entry is indicated by hh_len
being non-zero, and such initialization is always done with
the neighbour's lock held as a writer.Signed-off-by: David S. Miller

In WoWLAN, devices may use crypto keys for TX/RX
and could also implement GTK rekeying. If the
driver isn't able to retrieve replay counters and
similar information from the device upon resume,
or if the device isn't responsive due to platform
issues, it isn't safe to keep the connection up
as GTK rekey messages from during the sleep time
could be replayed against it.The only protection against that is disconnecting
from the AP. Modifying mac80211 to do that while
it is resuming would be very complex and invasive
in the case that the driver requires a reconfig,
so do it after it has resumed completely. In that
case, however, packets might be replayed since it
can then only happen after TX/RX are up again, so
mark keys for interfaces that need to disconnect
as "tainted" and drop all packets that are sent
or received with those keys.Signed-off-by: Johannes Berg

This never, ever, happens.
Neighbour entries are always tied to one address family, and therefore
one set of dst_ops, and therefore one dst_ops->protocol "hh_type"
value.This capability was blindly imported by Alexey Kuznetsov when he wrote
the neighbour layer.Signed-off-by: David S. Miller

Get rid of all of the useless and costly indirection
by doing the neigh hash table lookup directly inside
of the neighbour binding.Rename from arp_bind_neighbour to rt_bind_neighbour.
Use new helpers {__,}ipv4_neigh_lookup()
In rt_bind_neighbour() get rid of useless tests which
are never true in the context this function is called,
namely dev is never NULL and the dst->neighbour is
always NULL.Signed-off-by: David S. Miller

Because struct rpcbind_args *map was declared static, if two
threads entered this method at the same time, the values
assigned to map could be sent two two differen tasks.
This could cause all sorts of problems, include use-after-free
and double-free of memory.Fix this by removing the static declaration so that the map
pointer is on the stack.Signed-off-by: Ben Greear

And mask the hash function result by simply shifting
down the "->hash_shift" most significant bits.Currently which bits we use is arbitrary since jhash
produces entropy evenly across the whole hash function
result.But soon we'll be using universal hashing functions,
and in those cases more entropy exists in the higher
bits than the lower bits, because they use multiplies.Signed-off-by: David S. Miller

In some cases it will be useful having the key size used for
encrypting the link. For example, some profiles may restrict
some operations depending on the key length.The key size is stored in the key that is passed to userspace
using the pin_length field in the key structure.For now this field is only valid for LE controllers. 3.0+HS
controllers define the Read Encryption Key Size command, this
field is intended for storing the value returned by that
command.Signed-off-by: Vinicius Costa Gomes
