cc24becae3 ipv6: White-space cleansing : Structure layouts
This patch makes no changes to the logic of the code but simply addresses
coding style issues as detected by checkpatch.

Both objdump and diff -w show no differences.

This patch addresses structure definitions, specifically it cleanses the brace
placement and replaces spaces with tabs in a few places.

b3b2b9e192 ipsec: Don't update the pmtu on ICMPV6_DEST_UNREACH
Currently we update the pmtu in the IPsec protocol error handlers
if icmpv6 message type is either ICMPV6_DEST_UNREACH or
ICMPV6_PKT_TOOBIG. Updating the pmtu on ICMPV6_DEST_UNREACH
is wrong in any case, it causes strangely fragmented packets.
Only ICMPV6_PKT_TOOBIG signalizes pmtu discovery, so remove the
ICMPV6_DEST_UNREACH check in the IPsec protocol error handlers.

b55b76b221 ipv6:introduce function to find route for redirect
RFC 4861 says that the IP source address of the Redirect is the
same as the current first-hop router for the specified ICMP
Destination Address, so the gateway should be taken into
consideration when we find the route for redirect.

There was once a check in commit
a6279458c5 ("NDISC: Search over
all possible rules on receipt of redirect.") and the check
went away in commit b94f1c0904
("ipv6: Use icmpv6_notify() to propagate redirect, instead of
rt6_redirect()").

The bug is only "exploitable" on layer-2 because the source
address of the redirect is checked to be a valid link-local
address but it makes spoofing a lot easier in the same L2
domain nonetheless.

Thanks very much for Hannes's help.

81aded2467 ipv6: Handle PMTU in ICMP error handlers.
One tricky issue on the ipv6 side vs. ipv4 is that the ICMP callouts
to handle the error pass the 32-bit info cookie in network byte order
whereas ipv4 passes it around in host byte order.

Like the ipv4 side, we have two helper functions.  One for when we
have a socket context and one for when we do not.

ip6ip6 tunnels are not handled here, because they handle PMTU events
by essentially relaying another ICMP packet-too-big message back to
the original sender.

This patch allows us to get rid of rt6_do_pmtu_disc().  It handles all
kinds of situations that simply cannot happen when we do the PMTU
update directly using a fully resolved route.

In fact, the "plen == 128" check in ip6_rt_update_pmtu() can very
likely be removed or changed into a BUG_ON() check.  We should never
have a prefixed ipv6 route when we get there.

Another piece of strange history here is that TCP and DCCP, unlike in
ipv4, never invoke the update_pmtu() method from their ICMP error
handlers.  This is incredibly astonishing since this is the context
where we have the most accurate context in which to make a PMTU
update, namely we have a fully connected socket and associated cached
socket route.

10e7454ed7 ipcomp: Avoid duplicate calls to ipcomp_destroy
When ipcomp_tunnel_attach fails we will call ipcomp_destroy twice.
This may lead to double-frees on certain structures.

As there is no reason to explicitly call ipcomp_destroy, this patch
removes it from ipcomp*.c and lets the standard xfrm_state destruction
take place.

This is based on the discovery and patch by Alexey Dobriyan.

I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
  rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
  (as it should), and unregistering involves rcu barriers by itself

So it looks nothing should be done.

21e43188f2 [IPCOMP]: Disable BH on output when using shared tfm
Because we use shared tfm objects in order to conserve memory,
(each tfm requires 128K of vmalloc memory), BH needs to be turned
off on output as that can occur in process context.

Previously this was done implicitly by the xfrm output code.
That was lost when it became lockless.  So we need to add the
BH disabling to IPComp directly.

e40b328615 [IPSEC]: Forbid BEET + ipcomp for now
While BEET can theoretically work with IPComp the current code can't
do that because it tries to construct a BEET mode tunnel type which
doesn't (and cannot) exist.  In fact as it is it won't even attach a
tunnel object at all for BEET which is bogus.

To support this fully we'd also need to change the policy checks on
input to recognise a plain tunnel as a legal variant of an optional
BEET transform.

This patch simply fails such constructions for now.

ESP.

007f0211a8 [IPSEC]: Store IPv6 nh pointer in mac_header on output
Current the x->mode->output functions store the IPv6 nh pointer in the
skb network header.  This is inconvenient because the network header then
has to be fixed up before the packet can leave the IPsec stack.  The mac
header field is unused on output so we can use that to store this instead.

This patch does that and removes the network header fix-up in xfrm_output.

It also uses ipv6_hdr where appropriate in the x->type->output functions.

There is also a minor clean-up in esp4 to make it use the same code as
esp6 to help any subsequent effort to merge the two.

Lastly it kills two redundant skb_set_* statements in BEET that were
simply copied over from transport mode.
