is also needed for ila (even though the config that triggered the issue
was pathological, but still, we don't want that to happen).

ila: block BH in ila_output()

As explained in commit 1378817486d6 ("tipc: block BH
before using dst_cache"), net/core/dst_cache.c
helpers need to be called with BH disabled.

ila_output() is called from lwtunnel_output()
possibly from process context, and under rcu_read_lock().

We might be interrupted by a softirq, re-enter ila_output()
and corrupt dst_cache data structures.

Fix the race by using local_bh_disable().

Merge branch 'ipv6-add-rpl-source-routing'

Alexander Aring says:

====================
net: ipv6: add rpl source routing

This patch series will add handling for RPL source routing handling
and insertion (implement as lwtunnel)! I did an example prototype
implementation in rpld for using this implementation in non-storing mode:

https://github.com/linux-wpan/rpld/tree/nonstoring_mode

I will also present a talk at netdev about it:

https://netdevconf.info/0x14/session.html?talk-extend-segment-routing-for-RPL

In receive handling I add handling for IPIP encapsulation as RFC6554
describes it as possible. For reasons I didn't implemented it yet for
generating such packets because I am not really sure how/when this
should happen. So far I understand there exists a draft yet which
describes the cases (inclusive a Hop-by-Hop option which we also not
support yet).

https://tools.ietf.org/html/draft-ietf-roll-useofrplinfo-35

This is just the beginning to start implementation everything for yet,
step by step. It works for my use cases yet to have it running on a
6LOWPAN _only_ network.

I have some patches for iproute2 as well.

A sidenote: I check on local addresses if they are part of segment
routes, this is just to avoid stupid settings. A use can add addresses
afterwards what I cannot control anymore but then it's users fault to
make such thing. The receive handling checks for this as well which is
required by RFC6554, so the next hops or when it comes back should drop
it anyway.

To make this possible I added functionality to pass the net structure to
the build_state of lwtunnel (I hope I caught all lwtunnels).

Another sidenote: I set the headroom value to 0 as I figured out it will
break on interfaces with IPv6 min mtu if set to non zero for tunnels on
L3.

- Alex

changes since v3:
- use parse_nested which isn't deprecated - Thanks David Ahern
- change to return -1 instead errno in exthdr handling to unify
error code
- change function name from ipv6_rpl_srh_decompress_size to
ipv6_rpl_srh_size

changes since v2:
- add additional segdata length in lwtunnel build_state
- fix build_state patch by not catching one inline noop function
if LWTUNNEL is disabled
