Kalle Valo 310c01afae ath10k: add directory to board data error message
This way user has a better idea what file exactly is missing.
This is needed when we switch to using request_firmware_direct() which doesn't
print any errors anymore.

Erik Stromdahl 1c61bedc0a ath10k: fetch firmware images in a loop
To make it easier to handle minimum and maximum firmware API numbers convert
the firmware fetch functionality to a loop. If no firmware image is found print
an error with minimum and maximum API numbers and the name of firmware
directory. This is needed when we switch to using request_firmware_direct()
which doesn't print any errors anymore.

Also add a new function for creating the fw file name dynamically which makes it
easier to add new bus support, for example SDIO and USB, later.

====================
sfc: prevent bogus interrupt-mode fallbacks

EF10 VFs only support MSI-X interrupts, not MSI or legacy.  This series
 stops the probe logic from trying to fallback to those if MSI-X interrupt
 probe fails.  It also prevents selecting them with the interrupt_mode
 module parameter.
This avoids producing messages like "failed to hook legacy IRQ 0" and "IRQ
 handler type mismatch for IRQ 0", and ensures that the relevant error
 (from the attempt to enable MSI-X) is reported to the caller.

We can simplify the logic of entries pointing to the bridge by
converging the fdb_delete_by functions, this would allow us to use the
same function for both cases since the fdb's dst is set to NULL if it is
pointing to the bridge thus we can always check for a port match.

two flavors: br_fdb_find() which requires hash_lock and br_fdb_find_rcu

remove two abusers of __br_fdb_get which called it under hash_lock and

Kalle Valo 1427228d58 ath10k: fix napi crash during rmmod when probe firmware fails
This fixes the below crash when ath10k probe firmware fails, NAPI polling tries
to access a rx ring resource which was never allocated. An easy way to
reproduce this is easy to remove all the firmware files, load ath10k modules
and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to call
napi_enable() from ath10k_pci_hif_start() so that it matches with
napi_disable() being called from ath10k_pci_hif_stop().

Big thanks to Mohammed Shafi Shajakhan who debugged this and provided first
version of the fix. In this patch I just fix the actual problem in pci.c
instead of having a workaround in core.c.

David S. Miller 144adc655f Merge branch 'ipv6-v4mapped'
Jonathan T. Leighton says:

====================
IPv4-mapped on wire, :: dst address issue

Under some circumstances IPv6 datagrams are sent with IPv4-mapped IPv6
addresses as the source. Given an IPv6 socket bound to an IPv4-mapped
IPv6 address, and an IPv6 destination address, both TCP and UDP will
will send packets using the IPv4-mapped IPv6 address as the source. Per
RFC 6890 (Table 20), IPv4-mapped IPv6 source addresses are not allowed
in an IP datagram. The problem can be observed by attempting to
connect() either a TCP or UDP socket, or by using sendmsg() with a UDP
socket. The patch is intended to correct this issue for all socket
types.

linux follows the BSD convention that an IPv6 destination address
specified as in6addr_any is converted to the loopback address.
Currently, neither TCP nor UDP consider the possibility that the source
address is an IPv4-mapped IPv6 address, and assume that the appropriate
loopback address is ::1. The patch adds a check on whether or not the
source address is an IPv4-mapped IPv6 address and then sets the
destination address to either ::ffff:127.0.0.1 or ::1, as appropriate.

Jonathan T. Leighton 052d2369d1 ipv6: Handle IPv4-mapped src to in6addr_any dst.
This patch adds a check on the type of the source address for the case
where the destination address is in6addr_any. If the source is an
IPv4-mapped IPv6 source address, the destination is changed to
::ffff:127.0.0.1, and otherwise the destination is changed to ::1. This
is done in three locations to handle UDP calls to either connect() or
sendmsg() and TCP calls to connect(). Note that udpv6_sendmsg() delays
handling an in6addr_any destination until very late, so the patch only
needs to handle the case where the source is an IPv4-mapped IPv6
address.

====================
40GbE Intel Wired LAN Driver Updates 2017-02-11

This series contains updates to i40e and i40evf only.

Jake makes a minor change to prevent a minor bit of work, if it is not
necessary.  In the case where we do not have a client, there is no need
to check the client params, so move the check till after we have ensured
we have a client.  Correct a code comment which incorrectly implied
that raw_packet buffers were freed in i40e_clean_tx_ring(), so fixed
the code comment to better explain where memory is freed.  Reduce the
severity and frequency of the message notifying we cleared the receive
timestamp register, since the logic has a much better detection scheme
that could detect a stalled receive timestamp register.  The improved
logic was actually causing the notification message to occur more
frequently and was giving the user a false perception that a timestamp
event was missed for a valid packet, so reduce the severity from
dev_warn to dev_dbg and only fire off the message when 3 or 4 of the
RXTIME registers are stalled and get cleared within the same
watchdog event.  Fixed a bug, where we were modifying the mac_filter
outside a lock when handling the addition of broadcast filters.  Fix
this by updating i40e_update_filter_state logic so that it knows to
avoid broadcast filters, which ensures that we do not have to remove
the filter separately and can put it back using the normal flow.
Refactored how we add new filters to firmware to avoid a race condition
that can occur due to removing filters from the hash temporarily.

Mitch adds a sleep (without timeout) so that we wait for a reply from
the PF before we continue, since the iWarp client cannot continue until
the operation is completed.  Fixed up a function which could never
return an error, to be void and cleaned up the checking of the now
null and void return value.

Scott limits the DMA sync to CPU to the actual length of the incoming
packet, versus the syncing of the entire buffer.  Also reduces the
receive buffer struct (by a single pointer) and align the driver to be
more consistent with other Intel drivers with respect to packets that
span buffers.

Sudheer adds a field to track the bus number info and modified log
statements to print bus, device and function information.

Henry adds the ability to store the FEC status bits from the link up
event.  Also adds the ethtool support for FEC capabilities and 25G
link types.

Herbert Xu 40137906c5 rhashtable: Add nested tables
This patch adds code that handles GFP_ATOMIC kmalloc failure on
insertion.  As we cannot use vmalloc, we solve it by making our
hash table nested.  That is, we allocate single pages at each level
and reach our desired table size by nesting them.

When a nested table is created, only a single page is allocated
at the top-level.  Lower levels are allocated on demand during
insertion.  Therefore for each insertion to succeed, only two
(non-consecutive) pages are needed.

After a nested table is created, a rehash will be scheduled in
order to switch to a vmalloced table as soon as possible.  Also,
the rehash code will never rehash into a nested table.  If we
detect a nested table during a rehash, the rehash will be aborted
and a new rehash will be scheduled.

it's doing a manual walk over an rhashtable.  This is broken as
an rhashtable can be resized and if you manually walk over it

Secondly it's missing memory barriers as previously the code used

When sending ARP requests over AX.25 links the hwaddress in the neighbour
cache are not getting initialized.  For such an incomplete arp entry
ax2asc2 will generate an empty string resulting in /proc/net/arp output
like the following:

$ cat /proc/net/arp
IP address       HW type     Flags       HW address            Mask     Device
192.168.122.1    0x1         0x2         52:54:00:00:5d:5f     *        ens3
172.20.1.99      0x3         0x0              *        bpq0

The missing field will confuse the procfs parsing of arp(8) resulting in
incorrect output for the device such as the following:

$ arp
Address                  HWtype  HWaddress           Flags Mask            Iface
gateway                  ether   52:54:00:00:5d:5f   C                     ens3
172.20.1.99                      (incomplete)                              ens3

This changes the content of /proc/net/arp to:

$ cat /proc/net/arp
IP address       HW type     Flags       HW address            Mask     Device
172.20.1.99      0x3         0x0         *                     *        bpq0
192.168.122.1    0x1         0x2         52:54:00:00:5d:5f     *        ens3

To do so it change ax2asc to put the string "*" in buf for a NULL address
argument.  Finally the HW address field is left aligned in a 17 character
field (the length of an ethernet HW address in the usual hex notation) for
readability.

Mart van Santen ebf692f85f xen-netback: vif counters from int/long to u64
This patch fixes an issue where the type of counters in the queue(s)
and interface are not in sync (queue counters are int, interface
counters are long), causing incorrect reporting of tx/rx values
of the vif interface and unclear counter overflows.
This patch sets both counters to the u64 type.

Hans Verkuil 42980da2eb [media] cec: initiator should be the same as the destination for, poll
Poll messages that are used to allocate a logical address should
use the same initiator as the destination. Instead, it expected that
the initiator was 0xf which is not according to the standard.

This also had consequences for the message checks in cec_transmit_msg_fh
that incorrectly rejected poll messages with the same initiator and
destination.

Hans Verkuil 35879ee476 [media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGB
This reverts 'commit 7e0739cd9c ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").

The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.

To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

David S. Miller caa137eea6 Merge branch 'mv88e6xxx-Watchdog-support'
Andrew Lunn says:

====================
mv88e6xxx Watchdog support

The Marvell switches have an in built watchdog over some of the
internal state machine. The watchdog can be configured to raise an
interrupt on error. The problem the watchdog found is then logged to
the kernel log.

The older switches can automagically perform a software reset when the
watchdog triggers. This just resets the internal state machine, but
leaves the switch configuration unchanged.

The 6390 family of switches cannot both raise an interrupt and
automagically perform a software reset. So the interrupt handler has
to perform the switch reset, and then re-enable the watchdog
interrupts.

This has been tested using hacked together debugfs code which allows
the "force" bit to be set, so cause a watchdog interrupt.

v2: Remove g2_prefix

Andrew Lunn fcd25166d9 net: dsa: mv88e6xxx: Add watchdog interrupt handler
The switch contains a watchdog looking for issues with the internal
gubbins of the switch. Hook the interrupt the watchdog triggers and
log the value of the control register indicating why the watchdog
fired. The watchdog can only be cleared with a switch reset, which
will destroy the current configuration. Rather than doing this, just
disable the interrupt.

The mv88e6390 family has different watchdog registers. So use an ops
structure, so support for the mv88e6390 family can be added later.
