net: add an ioctl to get a socket network namespace
Each socket operates in a network namespace where it has been created,
so if we want to dump and restore a socket, we have to know its network
namespace.
We have a socket_diag to get information about sockets, it doesn't
report sockets which are not bound or connected.
This patch introduces a new socket ioctl, which is called SIOCGSKNS
and used to get a file descriptor for a socket network namespace.
A task must have CAP_NET_ADMIN in a target network namespace to
use this ioctl.

mlxsw: Add Infiniband support for Mellanox switches
This patchset adds basic Infiniband support for SwitchX-2, Switch-IB
and Switch-IB-2 ASIC drivers.
SwitchX-2 ASIC is VPI capable, which means each port can be either
Ethernet or Infiniband. When the port is configured as Infiniband,
the Subnet Management Agent (SMA) is managed by the SwitchX-2 firmware
and not by the host. Port configuration, MTU and more are configured
remotely by the Subnet Manager (SM).
Usage:
$ devlink port show

Switch-IB (FDR) and Switch-IB-2 (EDR 100Gbs) ASICs are Infiniband-only
switches. The support provided in the mlxsw_switchib.ko driver is port

one of the registers was incorrectly set. This caused the firmware to
access garbage data that wasn't initialized by the driver and therefore
emit error messages.
While the bug is already fixed and the driver usually zeros the buffers
passed to the firmware, there are a handful of cases where this isn't
done. Zero the buffer in these cases and prevent similar bugs from
recurring, as they tend to be hard to debug.

Create/Destroy TSAR on Enable/Dsiable SRIOV.
Attach/Detach vport to eswitch TSAR on Enable/Disable vport.
TSAR (stands for Transmit Scheduling ARbiter) is a hardware component
that is responsible for selecting the next entity to serve on the
transmit path.
The arbitration defines the QoS policy between the agents connected to
the TSAR.
The TSAR is a consist two main features:
1) BW Allocation between agents:
The TSAR implements a defecit weighted round robin between the agents.
Each agent attached to the TSAR is assigned with a weight and it is
awarded transmission tokens according to this weight.
2) Rate limer per agent:
Each agent attached to the TSAR is (optionally) assigned with a rate
limit.
TSAR will not allow scheduling for an agent exceeding its defined rate
limit.

When MTU is changed from 9000 to 1500 while there is burst of inbound 9000
bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes
buffers. This causes memory corruption and sometimes crash.
This is because of a race condition in adaptor between "RQ disable"
clearing descriptor mini-cache and mini-cache valid bit being set by
completion of descriptor fetch. This can result in stale RQ desc being
cached and used when packets arrive. In this case, the stale descriptor
have old MTU value.
Solution is to write RQ->disable twice. The first write will stop any
further desc fetches, allowing the second disable to clear the mini-cache
valid bit without danger of a race.
Also, the check for rq->running becoming 0 after writing rq->enable to 0
is not done properly. When incoming packets are flooding the interface,
rq->running will pulse high for each dropped packet. Since the driver was
waiting for 10us between each poll, it is possible to see rq->running = 1
1000 times in a row, even though it is not actually stuck running.
This results in false failure of vnic_rq_disable(). Fix is to try more
than 1000 time without delay between polls to ensure we do not miss when
running goes low.
In old adaptors rq->enable needs to be re-written to 0 when posted_index
is reset in vnic_rq_clean() in order to keep rq->prefetch_index in sync.

tipc: fix broadcast link synchronization problem
In commit 2d18ac4ba745 ("tipc: extend broadcast link initialization
criteria") we tried to fix a problem with the initial synchronization
of broadcast link acknowledge values. Unfortunately that solution is
not sufficient to solve the issue.
We have seen it happen that LINK_PROTOCOL/STATE packets with a valid
non-zero unicast acknowledge number may bypass BCAST_PROTOCOL
initialization, NAME_DISTRIBUTOR and other STATE packets with invalid
broadcast acknowledge numbers, leading to premature opening of the
broadcast link. When the bypassed packets finally arrive, they are
inadvertently accepted, and the already correctly initialized
acknowledge number in the broadcast receive link is overwritten by
the invalid (zero) value of the said packets. After this the broadcast
link goes stale.
We now fix this by marking the packets where we know the acknowledge
value is or may be invalid, and then ignoring the acks from those.
To this purpose, we claim an unused bit in the header to indicate that
the value is invalid. We set the bit to 1 in the initial BCAST_PROTOCOL
synchronization packet and all initial ("bulk") NAME_DISTRIBUTOR
packets, plus those LINK_PROTOCOL packets sent out before the broadcast
links are fully synchronized.
This minor protocol update is fully backwards compatible.

net/mlx4_en: Fix potential deadlock in port statistics flow
mlx4_en_DUMP_ETH_STATS took the *counter mutex* and then
called the FW command, with WRAPPED attribute. As a result, the fw command
is wrapped on the Hypervisor when it calls mlx4_en_DUMP_ETH_STATS.
The FW command wrapper flow on the hypervisor takes the *slave_cmd_mutex*
during processing.
At the same time, a VF could be in the process of coming up, and could
call mlx4_QUERY_FUNC_CAP. On the hypervisor, the command flow takes the
*slave_cmd_mutex*, then executes mlx4_QUERY_FUNC_CAP_wrapper.
mlx4_QUERY_FUNC_CAP wrapper calls mlx4_get_default_counter_index(),
which takes the *counter mutex*. DEADLOCK.
The fix is that the DUMP_ETH_STATS fw command should be called with
the NATIVE attribute, so that on the hypervisor, this command does not
enter the wrapper flow.
Since the Hypervisor no longer goes through the wrapper code, we also
simply return 0 in mlx4_DUMP_ETH_STATS_wrapper (i.e.the function succeeds,
but the returned data will be all zeroes).
No need to test if it is the Hypervisor going through the wrapper.

net/mlx4_core: Do not access comm channel if it has not yet been initialized
In the Hypervisor, there are several FW commands which are invoked
before the comm channel is initialized (in mlx4_multi_func_init).
These include MOD_STAT_CONFIG, QUERY_DEV_CAP, INIT_HCA, and others.
If any of these commands fails, say with a timeout, the Hypervisor
driver enters the internal error reset flow. In this flow, the driver
attempts to notify all slaves via the comm channel that an internal error
has occurred.
Since the comm channel has not yet been initialized (i.e., mapped via
ioremap), this will cause dereferencing a NULL pointer.
To fix this, do not access the comm channel in the internal error flow
if it has not yet been initialized.

40GbE Intel Wired LAN Driver Updates 2016-10-28
This series contains updates to i40e and i40evf only.
Carolyn provides a couple of fixes, first resolving a problem in the
client interface that was causing random stack traces in the RDMA driver
which was due to a timing related NULL pointer dereference. Fixed a
problem where it could take a very long time to print the link down
notification, by changing how often we update link info from firmware.
Alex provides a number of changes, first is a re-write of the bust wait
loop in the Flow Director transmit function to reduce code size. Cleans
up unused code in favor of the same functionality which can be inlined.
Dropped the functionality for SCTP since we cannot currently support it.
Cleans up redundant code in the receive clean-up path. Finally cleaned
up the convoluted configuration for how the driver handled the debug
flags contained in msg_level.
Filip fixes an incorrect bit mask which was being used for testing the
"get link status". Cleaned up a workaround that is no longer needed
for production NICs and was causing frames to pass while disregarding
the VLAN tagging.
Mitch brings another fix for the client interface supporting the VF RDMA
driver to allow clients to recover from reset by re-opening existing
clients.
Alan fixes a bug in which a "perfect storm" can occur and cause interrupts
to fail to be correctly affinitized.
Lihong fixes a confusing dmesg reported when users were using ethtool -L

Currently, BPF samples are including some of the kernel headers and mid
term we should change them to refrain from this, really. When dynamic
debugging is enabled, we bail out due to undeclared KBUILD_MODNAME, which
is easily overlooked in the build as clang spills this along with other
noisy warnings from various header includes, and llc still generates an
ELF file with mentioned characteristics. For just playing around with BPF

The i.MX fixes for 4.9:
- A couple of patches from Fabio to fix the GPC power domain regression
which is caused by PM Domain core change 0159ec670763dd
("PM / Domains: Verify the PM domain is present when adding a
provider"), and a related kernel crash seen with multi_v7_defconfig
build.
- Correct the PHY ID mask for AR8031 to match phy driver code.
- Apply new added timer erratum A008585 for LS1043A and LS2080A SoC.
- Correct vf610 global timer IRQ flag to avoid warning from gic driver
after commit 992345a58e0c ("irqchip/gic: WARN if setting the
interrupt type for a PPI fails").

Pull driver core fixes from Greg KH:
"Here are two small driver core / kernfs fixes for 4.9-rc3.
One makes the Kconfig entry for DEBUG_TEST_DRIVER_REMOVE a bit more
explicit that this is a crazy thing to enable for a distro kernel
(thanks for trying Fedora!), the other resolves an issue with vim
opening kernfs files (sysfs, configfs, etc.)
Both have been in linux-next with no reported issues"
* tag 'driver-core-4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
driver core: Make Kconfig text for DEBUG_TEST_DRIVER_REMOVE stronger
kernfs: Add noop_fsync to supported kernfs_file_fops
