4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
5) When we encapsulate for a tunnel device, skb->sk still points to the
user socket. So this leads to cases where we retraverse the
ipv4/ipv6 output path with skb->sk being of some other address
family (f.e. AF_PACKET). This can cause things to crash since the
ipv4 output path is dereferencing an AF_PACKET socket as if it were
an ipv4 one.
The short term fix for 'net' and -stable is to elide these socket
checks once we've entered an encapsulation sequence by testing
xmit_recursion.
Longer term we have a better solution wherein we pass the tunnel's
socket down through the output paths, but that is way too invasive
for 'net' and -stable.

configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.
However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.
This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.
This was tested on a custom board with two Marvell
88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

tc: bpf: add checksum helpers
Commit
608cd71a9c7c ("tc: bpf: generalize pedit action") has added the

This patch adds two helpers bpf_l3_csum_replace() and bpf_l4_csum_replace()
for fixing up the protocol checksums after the packet mangling.
It also adds 'flags' argument to bpf_skb_store_bytes() helper to avoid
unnecessary checksum recomputations when BPF programs adjusting l3/l4

Moreover, a sample program is added to show how BPF programs can make use

ipv6: protect skb->sk accesses from recursive dereference inside the stack
We should not consult skb->sk for output decisions in xmit recursion

the result of e.g. tunnel encapsulation process.
ipv6 does not conform with this in three places:
1) ip6_fragment: we do consult ipv6_npinfo for frag_size
2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
loop the packet back to the local socket
3) ip6_skb_dst_mtu could query the settings from the user socket and
force a wrong MTU
Furthermore:
In sk_mc_loop we could potentially land in WARN_ON(1) if we use a

This has been tested on a Dell Latitude E6400, where the DualPoint Stick

Merge branch 'nf-hook-compress'
netfilter: Compress hook function signatures.
Currently netfilter hooks have a function signature that is huge and
has many arguments. This propagates from the hook entry points down
into the individual hook implementations themselves.
This means that if, for example, we want to change the type of one of
these arguments then we have to touch hundreds of locations.
The main initial motivation behind this is that we'd like to change
the signature of "okfn" so that a socket pointer can be passed in (and
reference counted properly) for the sake of using the proper socket
context in the case of tunnels whilst not releasing the top level user
socket from skb->sk (and thus releasing it's socket memory quota
usage) in order to accomodate this.
This also makes it clear who actually uses 'okfn', nf_queue(). It is
absolutely critical to make this obvious because any user of 'okfn'
down in these hook chains have the be strictly audited for
escapability. Specifically, escapability of references to objects
outside of the packet processing path. And that's exactly what
nf_queue() does via it's packet reinjection framework.
In fact this points out a bug in Jiri's original attempt to push the
socket pointer down through netfilter's okfn. It didn't grab and drop
a reference to the socket in net/netfilter/nf_queue.c as needed.
Furthermore, so many code paths are simplified, and should in fact be
more efficient because we aren't passing in arguments that often are
simply not used by the netfilter hook at all.
Further simplifications are probably possible, but this series takes
care of the main cases.
Unfortunately I couldn't convert ebt_do_table() because ebtables is
complete and utter crap and uses ebt_do_table() outside of the hook
call chains. But that should not be news to anyone.

Merge branch 'mvneta-sgmii'
Stas Sergeev says:
====================
mvneta: SGMII-based in-band link state signaling
Currently the fixed-link DT binding is pre-configured and
cannot be changed in run-time. This means the cable unplug
events are not being detected, and the link parameters can't
be negotiated.
The following patches are needed when mvneta is used
in fixed-link mode (without MDIO).
They add an API to fixed_phy that allows to update
status, and use that API in the mvneta driver when parsing
the SGMII in-band status.
There is also another implementation that doesn't add any API
and does everything in mvneta driver locally:
https://lkml.org/lkml/2015/3/31/327
I'll let people decide which approach is better.
No strong opinion on my side.

mvneta: implement SGMII-based in-band link state signaling
When MDIO bus is unavailable (common setup for SGMII), the in-band
signaling must be used to correctly track link state.
This patch enables the in-band status delivery for link state changes, namely:
- link up/down
- link speed
- duplex full/half
fixed_phy_update_state() is used to update phy status.

add fixed_phy_update_state() - update state of fixed_phy
Currently fixed_phy uses a callback to periodically poll the link state.
This patch adds the fixed_phy_update_state() API.
It solves the following problems:
- On link state interrupt, MAC driver can't update status.
Instead it needs to provide the callback to periodically query
the HW about the link state. It is more efficient to update status
after interrupt.
- The callback needs to be unregistered before phy_disconnect(),
or otherwise it will be called with net_dev==NULL. phy_disconnect()
does not have enough info to unregister the callback automatically.
- The callback needs to be registered before of_phy_connect() to
avoid running with outdated state, but of_phy_connect() returns the
phy_device pointer, which is needed to register the callback. Registering
it before of_phy_connect() will therefore require a hack to get the
pointer earlier.
Overall, this addition makes the subsequent patch that implements
SGMII link status for mvneta, much cleaner.

ebpf: add skb->priority to offset map for usage in {cls, act}_bpf
This adds the ability to read out the skb->priority from an eBPF
program, so that it can be taken into account from a tc filter
or action for the use-case where the priority is not being used
to directly override the filter classification in a qdisc, but
to tag traffic otherwise for the classifier; the priority can be
assigned from various places incl. user space, in future we may
also mangle it from an eBPF program.
