Eric Dumazet noticed that all no-nonexthop or no-gateway routes which
are already marked DST_HOST (e.g. input routes routes) will always be
invalidated during sk_dst_check. Thus per-socket dst caching absolutely
had no effect and early demuxing had no effect.
Thus this patch removes rt6i_genid: fn_sernum already gets modified during
add operations, so we only must ensure we mutate fn_sernum during ipv6
address remove operations. This is a fairly cost extensive operations,
but address removal should not happen that often. Also our mtu update
functions do the same and we heard no complains so far. xfrm policy
changes also cause a call into fib6_flush_trees. Also plug a hole in
rt6_info (no cacheline changes).
I verified via tracing that this change has effect.

Erez Shitrit found that at most two segments were aggregated and
the "if (skb_gro_len(p) != pinfo->gso_size)" test was failing.
This is because pinfo at this spot still points to the last skb in the
chain, instead of the first one, where we find the correct gso_size

Pull networking fixes from David Miller:
1) If the user gives us a msg_namelen of 0, don't try to interpret
anything pointed to by msg_name. From Ani Sinha.
2) Fix some bnx2i/bnx2fc randconfig compilation errors.
The gist of the issue is that we firstly have drivers that span both
SCSI and networking. And at the top of that chain of dependencies
we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are
selected.
But since select is a sledgehammer and ignores dependencies,
everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also
explicitly select their dependencies and so on and so forth.
Generally speaking 'select' is supposed to only be used for child
nodes, those which have no dependencies of their own. And this
whole chain of dependencies in the scsi layer violates that rather
strongly.
So just make SCSI_NETLINK depend upon it's dependencies, and so on
and so forth for the things selecting it (either directly or
indirectly).

The bridge code checks if vlan filtering is enabled on both
ingress and egress. When the state flip happens, it
is possible for the bridge to currently be forwarding packets
and forwarding behavior becomes non-deterministic. Bridge
may drop packets on some interfaces, but not others.
This patch solves this by caching the filtered state of the
packet into skb_cb on ingress. The skb_cb is guaranteed to
not be over-written between the time packet entres bridge
forwarding path and the time it leaves it. On egress, we
can then check the cached state to see if we need to
apply filtering information.

enough for any moderate setups and, in case tickets themselves are not
encrypted, leads to buffer overflows (ceph_x_decrypt() errors out, but
ceph_decode_copy() doesn't - it's just a memcpy() wrapper). Since the

It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.
What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.
Fixes: commit a9ed4a2986 ("ipv6: fix rtnl locking in setsockopt for anycast and multicast")

This patch fix spelling typo found in DocBook/networking.xml.
It is because the neworking.xml is generated from comments
in the source, I have to fix typo in comments within the source.

Paul Bolle reports that 'select NETFILTER_XT_NAT' from the IPV4 and IPV6
NAT tables becomes noop since there is no Kconfig switch for it. Add the
Kconfig switch to resolve this problem.
Fixes: 8993cf8 netfilter: move NAT Kconfig switches out of the iptables scope
