The fix was to reorder napi_enable, napi_disable, request_irq and

Bjørn Mork 6527f833bf net: cdc_ncm: fix NULL pointer deref in cdc_ncm_bind_common
Commit 77b0a09967 ("cdc-ncm: use common parser") added a dangerous
new trust in the CDC functional descriptors presented by the device,
unconditionally assuming that any device handled by the driver has
a CDC Union descriptor.

This descriptor is required by the NCM and MBIM specs, but crashing
on non-compliant devices is still unacceptable. Not only will that
allow malicious devices to crash the kernel, but in this case it is
also well known that there are non-compliant real devices on the
market - as shown by the comment accompanying the IAD workaround
in the same function.

The Sierra Wireless EM7305 is an example of such device, having
a CDC header and a CDC MBIM descriptor but no CDC Union:

    Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber       12
      bAlternateSetting       0
      bNumEndpoints           1
      bInterfaceClass         2 Communications
      bInterfaceSubClass     14
      bInterfaceProtocol      0
      iInterface              0
      CDC Header:
        bcdCDC               1.10
      CDC MBIM:
        bcdMBIMVersion       1.00
        wMaxControlMessage   4096
        bNumberFilters       16
        bMaxFilterSize       128
        wMaxSegmentSize      4064
        bmNetworkCapabilities 0x20
          8-byte ntb input size
      Endpoint Descriptor:
	..

The conversion to a common parser also left the local cdc_union
variable untouched.  This caused the IAD workaround code to be applied
to all devices with an IAD descriptor, which was never intended.  Finish
the conversion by testing for hdr.usb_cdc_union_desc instead.

pull-request: can 2015-11-23

this is a pull request of three patches for the upcoming v4.4 release.

The first patch is by Mirza Krak, it fixes a problem with the sja1000 driver
after resuming from suspend to disk, by clearing all outstanding interrupts.
Oliver Hartkopp contributes two patches targeting almost all driver, they fix
the assignment of the error location in CAN error messages.

updated broadcom_tbl to use PHY_IDs, but incorrectly replaced 0x0143bca0

Nikolay Aleksandrov 7f109f7cc3 vrf: fix double free and memory corruption on register_netdevice failure
When vrf's ->newlink is called, if register_netdevice() fails then it
does free_netdev(), but that's also done by rtnl_newlink() so a second
free happens and memory gets corrupted, to reproduce execute the
following line a couple of times (1 - 5 usually is enough):
$ for i in `seq 1 5`; do ip link add vrf: type vrf table 1; done;
This works because we fail in register_netdevice() because of the wrong
name "vrf:".

Oliver Hartkopp a2ec19f888 can: remove obsolete assignment for CAN protocol error type
The assignment 'cf->data[2] |= CAN_ERR_PROT_UNSPEC' used at CAN error message
creation time is obsolete as CAN_ERR_PROT_UNSPEC is zero and cf->data[2] is
initialized with zero in alloc_can_err_skb() anyway.

So we could either assign 'cf->data[2] = CAN_ERR_PROT_UNSPEC' correctly or we
can remove the obsolete OR operation entirely.

Oliver Hartkopp ffd461f80d can: fix assignment of error location in CAN error messages
As Dan Carpenter reported in http://marc.info/?l=linux-can&m=144793696016187
the assignment of the error location in CAN error messages had some bit wise
overlaps. Indeed the value to be assigned in data[3] is no bitfield but defines
a single value which points to a location inside the CAN frame on the wire.

This patch fixes the assignments for the error locations in error messages.

Mirza Krak 7cecd9ab80 can: sja1000: clear interrupts on start
According to SJA1000 data sheet error-warning (EI) interrupt is not
cleared by setting the controller in to reset-mode.

Then if we have the following case:
- system is suspended (echo mem > /sys/power/state) and SJA1000 is left
  in operating state
- A bus error condition occurs which activates EI interrupt, system is
  still suspended which means EI interrupt will be not be handled nor
  cleared.

If the above two events occur, on resume there is no way to return the
SJA1000 to operating state, except to cycle power to it.

By simply reading the IR register on start we will clear any previous
conditions that could be present.

Arnd Bergmann de92718883 net: tulip: turn compile-time warning into dev_warn()
The tulip driver causes annoying build-time warnings for allmodconfig
builds for all recent architectures:

dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined
dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined!

This is the last remaining warning for arm64, and I'd like to get rid of
it. We don't really know the cache line size, architecturally it would
be at least 16 bytes, but all implementations I found have 64 or 128
bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to
be the safe but slow default, and nobody who cares about performance these
days would use a tulip chip anyway, so we can just use that.

To save the next person the job of trying to find out what this is for
and picking a default for their architecture just to kill off the warning,
I'm now removing the preprocessor #warning and turning it into a pr_warn
or dev_warn that prints the equivalent information when the driver gets
loaded.

Sergei Shtylyov 508dc0648c ravb: fix WARNING in __free_irq()
When the R8A7795 support was  added to the driver, little attention was paid
to the ravb_open() error path: free_irq()  for the EMAC interrupt was called
uncoditionally, unlike request_irq(), and in  a wrong order as well...
As a result, on the R-Car gen2 SoCs I started getting the following in case
of a device  opening error:

Ben Pope 0208e951d5 ethernet/atheros/alx: add Killer E2400 device ID
This patch adds the PCI device ID (0xe0a1) and alx_pci_tbl entry for the
Killer E2400 Ethernet controller, modeled after the Killer E2200
controller support (0xe091) already present in the alx driver.

This patch was originally authored by Ben Pope, but it got held up by
issues in the commit message, so I'm resubmitting it on his behalf.

I've extensively used a kernel with this patch on a System76 serw9
laptop and am quite confident it works well (at least on the hardware I
have available for testing).

Note that as a favor to System76, Ubuntu has been carrying this as a
sauce patch in their 4.2 based Wily kernel, which presumably has given
it real-world testing on other E2400 equipped hardware (I don't know of
any Ubuntu kernel bugs filed about it):

It's safe to ignore the new skb in the ipvlan_xmit_* functions, because
they call ipvlan_rcv_frame with local == true, so that dev_forward_skb
is called and always takes ownership of the skb.

Timo Teräs 6c606fa32c via-velocity: unconditionally drop frames with bad l2 length
By default the driver allowed incorrect frames to be received. What is
worse the code does not handle very short frames correctly. The FCS
length is unconditionally subtracted, and the underflow can cause
skb_put to be called with large number after implicit cast to unsigned.
And indeed, an skb_over_panic() was observed with via-velocity.

This removes the module parameter as it does not work in it's
current state, and should be implemented via NETIF_F_RXALL if needed.

an attempt was made to fix a regression introduced in commit 1277fa2ab2
("rtlwifi: Remove the clear interrupt routine from all drivers").
Unfortunately, there were logic errors in that patch that prevented
affected boxes from booting even after that patch was applied.

The actual cause of the original problem is unknown as none of the
developers have systems that are affected.

Add support for IP1000A chips to dl2k driver.
IP1000A chip looks like a TC9020 with integrated PHY.

This allows IP1000A chips to work reliably because the ipg driver is
buggy - it loses packets under load and then completely stops
transmitting data.

Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps:
vendor=0x13f0 device=0x1023 (rev 0x41)
subsystem vendor=0x1043 device=0x8180

MAC address registers access needed to be changed from 8-bit to 16-bit
because 8-bit does not work on IP1000A. 8-bit access is not even
allowed in the TC9020 datasheet (although it worked). 16-bit access
works on both.

Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably
a rebranded TC9020):

Pavel Fedin 7750130d93 net: thunder: Check for driver data in nicvf_remove()
In some cases the crash is caused by nicvf_remove() being called from
outside. For example, if we try to feed the device to vfio after the
probe has failed for some reason. So, move the check to better place.

Yuval Mintz ab6d7846cf bnx2x: Fix VLANs null-pointer for 57710, 57711
Commit 05cc5a39dd "bnx2x: add vlan filtering offload" introduced
a regression in regard for vlans for 57710, 57711 adapters -
Loading 8021q module on a machine with such an adapter would cause
a null pointer dereference, as the driver mistakenly publishes it
has capabilities for vlan CTAG filtering.

Pavel Fedin cd998ecd2f net: smsc911x: Reset PHY during initialization
On certain hardware after software reboot the chip may get stuck and fail
to reinitialize during reset. This can be fixed by ensuring that PHY is
reset too.

Old PHY resetting method required operational MDIO interface, therefore
the chip should have been already set up. In order to be able to function
during probe, it is changed to use PMT_CTRL register.

The problem could be observed on SMDK5410 board.

Rajkumar Manoharan 6419fdbb6f ath10k: poll HTT send completion when CE 5 is unused
commit a70587b338 ("ath10k: configure copy engine 5 for HTT messages")
moved send completion polling under HTT Rx (CE 5) service routine. For
QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead
of CE 5. So send completion never be called. This is causing "failed to
transmit packet, dropping: -105" errors. Fix this by processing send
completion from CE 1 service routine instead of CE 5.

Sudeep Holla cef03d7e66 hwmon: (scpi) skip unsupported sensors properly
Currently it's assumed that firmware exports only the class of sensors
supported by the driver. However with newer firmware or SCPI protocol
revision, support for newer classes of sensors can be present.

The driver fails to probe with the following warning if an unsupported
class of sensor is encountered in the firmware.

sysfs: cannot create duplicate filename
	'/devices/platform/scpi/scpi:sensors/hwmon/hwmon0/'
------------[ cut here ]------------

PC is at sysfs_warn_dup+0x54/0x78

This patch fixes the above issue by skipping through the unsupported
class of SCPI sensors.
