Marcel Holtmann 4fba30f07f Bluetooth: btbcm: Introduce generic Broadcom Bluetooth support
The majority of Broadcom Bluetooth vendor commands are shared between
USB and UART transports. This creates a separate module that eventually
will hold all Broadcom specific commands, but for now just start with
the commands to change the Bluetooth public address and check for the
default address.

Marcel Holtmann 2d7cc19eeb Bluetooth: Remove hci_recv_stream_fragment function
The hci_recv_stream_fragment function should have never been introduced
in the first place. The Bluetooth core does not need to know anything
about the HCI transport protocol.

With all transport protocol specific detailed moved back into the
drivers where they belong (mainly generic USB and UART drivers), this
function can now be removed.

This reduces the size of hci_dev structure and also removes an exported
symbol from the Bluetooth core module.

Pull networking fixes from David Miller:

 1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
    previously SACK'd, from Neal Cardwell.

 2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
    from Cong WANG.

 3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
    from Cong WANG.

 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.

    From Hannes Frederic Sowa.

 6) l2tp_init() failure path forgets to unregister per-net ops, from
    Cong WANG.

Pavel Nakonechny 303038135a net: dsa: fix filling routing table from OF description
According to description in 'include/net/dsa.h', in cascade switches
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 }.

Commit 608cd71a9c ("tc: bpf: generalize pedit action") has added the
possibility to mangle packet data to BPF programs in the tc pipeline.
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
checksums and documents all three helpers in uapi header.

Moreover, a sample program is added to show how BPF programs can make use
of the mangle and csum helpers.

hannes@stressinduktion.org f60e5990d9 ipv6: protect skb->sk accesses from recursive dereference inside the stack
We should not consult skb->sk for output decisions in xmit recursion
levels > 0 in the stack. Otherwise local socket settings could influence
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
PF_PACKET socket ontop of an IPv6-backed vxlan device.

Reuse xmit_recursion as we are currently only interested in protecting
tunnel devices.

Note that since there is no way to distinguish these packets from an external

that we will be reporting PS/2 mouse events via this evdev node too, as we've

idle, and via dev2 when the touchpad and stick are used simultaneously.

This commit fixes this inconsistency by always reporting bare packets via

reported via dev2, this gets fixed in a later commit.

David S. Miller 5888b93b75 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.

David S. Miller cfdfab3146 netfilter: Create and use nf_hook_state.
Instead of passing a large number of arguments down into the nf_hook()
entry points, create a structure which carries this state down through
the hook processing layers.

This makes is so that if we want to change the types or signatures of
any of these pieces of state, there are less places that need to be
changed.

The TX power field in the LE advertising data should be placed last
since it needs to be possible to enable kernel controlled TX power,
but still allow for userspace provided flags field.
