6052d5e2a1 ibmvnic: Insert header on VLAN tagged received frame
This patch addresses a modification in the PAPR+ specification which now
defines a previously reserved value for vNIC capabilities. It indicates
whether the system firmware performs a VLAN header stripping on all VLAN
tagged received frames, in case it does, the behavior expected is for
the ibmvnic driver to be responsible for inserting the VLAN header.

Mike Maloney says:

====================
packet: Add option to create new fanout group with unique id.

Fanout uses a per net global namespace. A process that intends to create a
new fanout group can accidentally join an existing group. It is
not possible to detect this.

Add a socket option to specify on the first call to
setsockopt(..., PACKET_FANOUT, ...) to ensure that a new group is created.
Also add tests.

4a69a86420 packet: add PACKET_FANOUT_FLAG_UNIQUEID to assign new fanout group id.
Fanout uses a per net global namespace. A process that intends to create
a new fanout group can accidentally join an existing group. It is not
possible to detect this.

Add socket option PACKET_FANOUT_FLAG_UNIQUEID.  When specified the
supplied fanout group id must be set to 0, and the kernel chooses an id
that is not already in use.  This is an ephemeral flag so that
other sockets can be added to this group using setsockopt, but NOT
specifying this flag.  The current getsockopt(..., PACKET_FANOUT, ...)
can be used to retrieve the new group id.

We assume that there are not a lot of fanout groups and that this is not
a high frequency call.

The method assigns ids starting at zero and increases until it finds an
unused id.  It keeps track of the last assigned id, and uses it as a
starting point to find new ids.

69226896ad mdio_bus: Issue GPIO RESET to PHYs.
Some boards [1] leave the PHYs at an invalid state
during system power-up or reset thus causing unreliability
issues with the PHY which manifests as PHY not being detected
or link not functional. To fix this, these PHYs need to be RESET
via a GPIO connected to the PHY's RESET pin.

Some boards have a single GPIO controlling the PHY RESET pin of all
PHYs on the bus whereas some others have separate GPIOs controlling
individual PHY RESETs.

In both cases, the RESET de-assertion cannot be done in the PHY driver
as the PHY will not probe till its reset is de-asserted.
So do the RESET de-assertion in the MDIO bus driver.

15769ff8b6 Merge branch 'VSOCK-add-vsockmon'
Stefan Hajnoczi says:

====================
VSOCK: vsockmon virtual device to monitor AF_VSOCK sockets.

v5:
 * Change vsock_deliver_tap() API to avoid unnecessary skb creation
   [Jorgen]
 * Fix skb leak when no taps are registered [Jorgen]
 * s/cpu_to_le16(pkt->hdr.op)/le16_to_cpu(pkt->hdr.op)/ [Michael]
 * Add af_vsock_tap.c and vsockmon.[ch] to MAINTAINERS
 * checkpatch.pl and sparse fixes

v4:
 * Add explicit reserved padding field to struct af_vsockmon_hdr and
   drop __attribute__((packed)) [Michael, DaveM]
 * Call synchronize_net() before module_put() [Michael]

v3:
 * Hook virtio_transport.c (guest driver), not just drivers/vhost/vsock.c (host
   driver)
 * Fix DEFAULT_MTU macro definition [Zhu Yanjun]
 * Rename af_vsockmon_hdr->t field ->transport for clarity
 * Update .ndo_get_stats64() return type since it has changed
 * Include missing <linux/module.h> header in af_vsock_tap.c

This is a continuation of Gerard Garcia's work on the vsockmon packet capture
interface for AF_VSOCK.  Packet capture is an essential feature for network
communication.  Gerard began addressing this feature gap in his Google Summer
of Code 2016 project.  I have cleaned up, rebased, and retested the v2 series
he posted previously.

The design follows the nlmon packet capture interface closely.  This is because
vsock has the same problem as netlink: there is no netdev on which packets can
be captured.  The nlmon driver is a synthetic netdev purely for the purpose of
enabling packet capture.  We follow the same approach here with vsockmon.

See include/uapi/linux/vsockmon.h in this series for details on the packet
layout.

How to try it:

1. Build tcpdump with vsockmon patches:

  $ git clone -b vsock https://github.com/stefanha/libpcap
  $ (cd libcap && ./configure && make)
  $ git clone -b vsock https://github.com/stefanha/tcpdump
  $ (cd tcpdump && ./configure && make)

2. Build nc-vsock (a netcat-like tool):

  $ git clone https://github.com/stefanha/nc-vsock
  $ (cd nc-vsock && make)

3. Launch a virtual machine:

  # modprobe vhost_vsock
  # qemu-system-x86_64 -M accel=kvm -m 1024 -cpu host \
      -drive if=virtio,file=test.img,format=raw \
      -device vhost-vsock-pci,guest-cid=3

  (Assumes guest is running a kernel with this patch)

4. Capture AF_VSOCK traffic in guest and/or host:

  # modprobe vsockmon
  # ip link add type vsockmon
  # ip link set vsockmon0 up
  # tcpdump -i vsockmon0 -vvv

5. Communicate!

  (host)$ nc-vsock -l 1234
  (guest)$ nc-vsock 2 1234

82dfb540ae VSOCK: Add virtio vsock vsockmon hooks
The virtio drivers deal with struct virtio_vsock_pkt.  Add
virtio_transport_deliver_tap_pkt(pkt) for handing packets to the
vsockmon device.

We call virtio_transport_deliver_tap_pkt(pkt) from
net/vmw_vsock/virtio_transport.c and drivers/vhost/vsock.c instead of
common code.  This is because the drivers may drop packets before
handing them to common code - we still want to capture them.

Therefore, add the missing bit clear of HCI_UART_PROTO_READY to

hci_register_dev fails.

Without the fix, the functions of the Data Link protocol layer could
potentially be accessed after that layer has been closed. This
could lead to a crash as memory would have been freed in that layer.

If hci_register_dev() returns an error in hci_uart_init_work()
then the HCI_UART_REGISTERED bit gets erroneously set due to
a missing return statement. Therefore, add the missing return
statement.

The consequence of the missing return is that the HCI UART is not
registered but HCI_UART_REGISTERED is set which allows the code
to think that hu->hdev is safe to access but hu->hdev has been
freed so could lead to a crash.

1fb78fb6c6 Bluetooth: try to improve CONFIG_SERIAL_DEV_BUS dependency
With CONFIG_SERIAL_DEV_BUS=m, the hci_serdev.o file does not actually
get built into hci_uart.o as the Makefile doesn't pick it up, leading
to a link error with anything referring to it:

ERROR: "hci_uart_register_device" [drivers/bluetooth/hci_nokia.ko] undefined!
scripts/Makefile.modpost:91: recipe for target '__modpost' failed

Changing this in the Makefile would cause another problem when
hci_uart itself is built-in and cannot reference symbols from the
serdev module.

This tries to address both problems by introducing a new hidden
Kconfig symbol that controls both the compilation of hci_serdev.o
and whether the Nokia driver can be selected. This seems to address
the problem for me, though there might be a better way to do it.

f2edd9f67b Bluetooth: hci_ll: Fix NULL pointer deref on FW upload failure
Avoid NULL pointer dereference occurring due to freeing
skb containing an error pointer. It can easily be triggered
by using the driver with broken uart (i.e. due to misconfigured
pinmuxing).

Both conflict were simple overlapping changes.

In the kaweth case, Eric Dumazet's skb_cow() bug fix overlapped the
conversion of the driver in net-next to use in-netdev stats.

c70b17b775 netpoll: Check for skb->queue_mapping
Reducing real_num_tx_queues needs to be in sync with skb queue_mapping
otherwise skbs with queue_mapping greater than real_num_tx_queues
can be sent to the underlying driver and can result in kernel panic.

One such event is running netconsole and enabling VF on the same
device. Or running netconsole and changing number of tx queues via
ethtool on same device.

e.g.
Unable to handle kernel NULL pointer dereference

723b929ca0 ip6mr: fix notification device destruction
Andrey Konovalov reported a BUG caused by the ip6mr code which is caused
because we call unregister_netdevice_many for a device that is already
being destroyed. In IPv4's ipmr that has been resolved by two commits
long time ago by introducing the "notify" parameter to the delete
function and avoiding the unregister when called from a notifier, so
let's do the same for ip6mr.

ea8ffc0818 bonding: fix wq initialization for links created via netlink
Earlier patch 4493b81bea ("bonding: initialize work-queues during
creation of bond") moved the work-queue initialization from bond_open()
to bond_create(). However this caused the link those are created using
netlink 'create bond option' (ip link add bondX type bond); create the
new trunk without initializing work-queues. Prior to the above mentioned
change, ndo_open was in both paths and things worked correctly. The
consequence is visible in the report shared by Joe Stringer -

I've noticed that this patch breaks bonding within namespaces if
you're not careful to perform device cleanup correctly.

Here's my repro script, you can run on any net-next with this patch
and you'll start seeing some weird behaviour:

ip netns add foo
ip li add veth0 type veth peer name veth0+ netns foo
ip li add veth1 type veth peer name veth1+ netns foo
ip netns exec foo ip li add bond0 type bond
ip netns exec foo ip li set dev veth0+ master bond0
ip netns exec foo ip li set dev veth1+ master bond0
ip netns exec foo ip addr add dev bond0 192.168.0.1/24
ip netns exec foo ip li set dev bond0 up
ip li del dev veth0
ip li del dev veth1

The second to last command segfaults, last command hangs. rtnl is now
permanently locked. It's not a problem if you take bond0 down before
deleting veths, or delete bond0 before deleting veths. If you delete
either end of the veth pair as per above, either inside or outside the
namespace, it hits this problem.

Here's some kernel logs:
[ 1221.801610] bond0: Enslaving veth0+ as an active interface with an up link
[ 1224.449581] bond0: Enslaving veth1+ as an active interface with an up link

b18b745397 net: arc_emac: switch to phy_start()/phy_stop()
Currently driver use phy_start_aneg() in arc_emac_open() to bring
up PHY. But phy_start() function is more appropriate for this purposes.
Besides that it call phy_start_aneg() as part of PHY startup sequence
it also can correctly bring up PHY from error and suspended states.
So the patch replace phy_start_aneg() to phy_start().

Also the patch add call to phy_stop() to arc_emac_stop() to allow
the PHY device to be fully suspended when the interface is unused.

89087c456f bpf: Fix values type used in test_maps
Maps of per-cpu type have their value element size adjusted to 8 if it
is specified smaller during various map operations.

This makes test_maps as a 32-bit binary fail, in fact the kernel
writes past the end of the value's array on the user's stack.

To be quite honest, I think the kernel should reject creation of a
per-cpu map that doesn't have a value size of at least 8 if that's
what the kernel is going to silently adjust to later.

If the user passed something smaller, it is a sizeof() calcualtion
based upon the type they will actually use (just like in this testcase
code) in later calls to the map operations.

Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2017-04-20

This adds the basic infrastructure for IPsec hardware
offloading, it creates a configuration API and adjusts
the packet path.

1) Add the needed netdev features to configure IPsec offloads.

2) Add the IPsec hardware offloading API.

3) Prepare the ESP packet path for hardware offloading.

4) Add gso handlers for esp4 and esp6, this implements
   the software fallback for GSO packets.

5) Add xfrm replay handler functions for offloading.

6) Change ESP to use a synchronous crypto algorithm on
   offloading, we don't have the option for asynchronous
   returns when we handle IPsec at layer2.

7) Add a xfrm validate function to validate_xmit_skb. This
   implements the software fallback for non GSO packets.

8) Set the inner_network and inner_transport members of
   the SKB, as well as encapsulation, to reflect the actual
   positions of these headers, and removes them only once
   encryption is done on the payload.
   From Ilan Tayari.

9) Prepare the ESP GRO codepath for hardware offloading.

10) Fix incorrect null pointer check in esp6.
    From Colin Ian King.

11) Fix for the GSO software fallback path to detect the
    fallback correctly.
    From Ilan Tayari.

Please pull or let me know if there are problems.
