====================
40GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to i40e and i40evf.
Heinrich Schuchardt found a possible null pointer being dereferenced in
i40e_debug_aq(), fixed the issue by doing the variable assignment after
we are sure the pointer is not null.
Avinash fixed an issue when link was down, we were not showing the
correct advertised link modes.
Mitch cleans up a useless initializer since the variable is assigned
right away. Refactors the receive filter handling to properly track
filter adds and deletes so the driver will not lose filters during a
reset and up/down cycles. Also added a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Catherine removes a device id which is not needed (or used). Moves
a mutex lock since we need to lock the client list around the
i40e_client_release() call to prevent the release from interrupting
the client instances while they are being added.
Joshua adds Hyper-V specific VF device ids.
Amitoj Kaur Chawla cleans up a redundant memset() call before a memcpy().
Stefan Assmann adds the missing link advertise for some x710 NICs.
Tushar Dave fixes and issue found on SPARC, where a PF reset clears MAC
filters and if a platform-specific MAC address is used, the driver has
to explicitly write default MAC address to MAC filters otherwise all
incoming traffic destined to the default MAC address will be dropped
after reset.

When using an IPoIB bond currently only active-backup mode is a valid
use case and this commit strengthens it.
Since commit 2ab82852a270 ("net/bonding: Enable bonding to enslave
netdevices not supporting set_mac_address()") was introduced till
4.7-rc1, IPoIB didn't support the set_mac_address ndo, and hence the
fail over mac policy always applied to IPoIB bonds.
With the introduction of commit 492a7e67ff83 ("IB/IPoIB: Allow setting
the device address"), that doesn't hold and practically IPoIB bonds are
broken as of that. To fix it, lets go to fail over mac if the device
doesn't support the ndo OR this is IPoIB device.
As a by-product, this commit also prevents a stack corruption which
occurred when trying to copy 20 bytes (IPoIB) device address
to a sockaddr struct that has only 16 bytes of storage.

This patch offloads port mirroring directives to hw using the matchall TC
with action mirror. It includes both the implementation of the
ndo_setup_tc function for the spectrum driver and the spectrum hardware
offload configuration code.
The hardware offload code is basically two new functions which are capable
of adding and removing a new mirror ports pair. It is done using the MPAT,
MPAR and SBIB registers:
- A new Switch-Port Analyzer (SPAN) entry is added using MPAT to the 'to'
port.
- The 'to' port is bound to the SPAN entry using MPAR register.
- In case of egress SPAN, the 'to' port gets a new internal shared
buffer using SBIB register.
In addition, a new database was added to the mlxsw_sp struct to store all
the SPAN entries and their bound ports list. The number of supported SPAN
entries is determined by resource query.

The firmware in several ZTE devices (at least the MF823/831/910
modems/mifis) use OS fingerprinting to determine which type of device to
export. In addition, these devices export a REST API which can be used to
control the type of device. So far, on Linux, the devices have been seen as
RNDIS or CDC Ether.
When CDC Ether is used, devices of the same type are, as with RNDIS,
exported with the same, bogus random MAC address. In addition, the devices
(at least on all firmware revisions I have found) use the bogus MAC when
sending traffic routed from external networks. And as a final feature, the
devices sometimes export the link state incorrectly. There are also
references online to several other ZTE devices displaying this behavior,
with several different PIDs and MAC addresses.
This patch tries to improve the handling of ZTE devices by doing the
following:
* Create a new driver_info-struct that is used by ZTE devices that do not
have an explicit entry in the product table. This struct is the same as the
default cdc_ether driver info, but a new bind- and an rx_fixup-function
have been added.
* In the new bind function, we check if we have read a random MAC from the
device. If we have, then we generate a new random MAC address. This will
ensure that all devices get a unique MAC.
* The rx_fixup-function replaces the destination MAC address in the skb
with that of the device. I have not seen a revision of these devices that
behaves correctly (i.e., sets the right destination MAC), so I chose not to
do any comparison with for example the known, bogus addresses.
* The MF823/MF832/MF910 sometimes export cdc carrier on twice on connect
(the correct behavior is off then on). Work around this by manually setting
carrier to off if an on-notification is received and the NOCARRIER-bit is
not set.
This change will affect all devices, but it should take care of similar
mistakes made by other manufacturers. I tried to think of/look/test for
problems/regressions that could be introduced by this behavior, but could
not find any. However, my familiarity with this code path is not that
great, so there could be something I have overlooked.
I have tested this patch with multiple revisions of all three devices, and
they behave as expected. In other words, they all got a valid, random MAC,
the correct operational state and I can receive/sent traffic without
problems. I also tested with some other cdc_ether devices I have and did
not find any problems/regressions caused by the two general changes.
v3->v4:
* Forgot to remove unused variables, sorry about that (thanks David
Miller).
v2->v3:
* I had forgot to remove the random MAC generation from usbnet_cdc_bind()
(thanks Oliver).
* Rework logic in the ZTE bind-function a bit.
v1->v2:
* Only generate random MAC for ZTE devices (thanks Oliver Neukum).
* Set random MAC and do RX fixup for all ZTE devices that do not have a
product-entry, as the bogus MAC have been seen on devices with several
different PIDs/MAC addresses. In other words, it seems to be the default
behavior of ZTE CDC Ether devices (thanks Lars Melin).

Pull libnvdimm fix from Dan Williams:
"This contains a regression fix for a problem that was introduced in
v4.7-rc6.
In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device-
specific-method) format that the platform firmware implements for
nvdimm devices. We initially fixed a regression in probing the QEMU
DSM implementation by making acpi_check_dsm() tolerant of the way QEMU
reports the "0 DSMs supported" condition.
However, that broke HPE platforms since that tolerance caused the
driver to mistakenly match the 1-zero-byte response those platforms
give to "unknown" commands. Instead, we simply make the driver
tolerant of not finding any supported DSMs. This has been tested to
work with both QEMU and HPE platforms.
This commit has appeared in a -next release with no reported issues"

...
Call Trace:
parport_unregister_driver+0x65/0xc0 [parport]
SyS_delete_module+0x187/0x210
The sequence that builds up to this is:
1) plip is loaded and takes the parport device for exclusive use:
plip0: Parallel port at 0x378, using IRQ 7.
2) pps_parport then fails to grab the device:
pps_parport: parallel port PPS client
parport0: cannot grant exclusive access for device pps_parport
pps_parport: couldn't register with parport0
3) rmmod of pps_parport is then killed because it tries to access
pardev->name, but pardev (taken from port->cad) is NULL.
So add a check for NULL in the test there too.

I stumbled over a build error with COMPILE_TEST and CONFIG_OF
disabled:
drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe':
drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node'
The problem is that the newly added GPIO_TEGRA Kconfig symbol
does not have a dependency on CONFIG_OF. However, there is another
problem here as the driver gets enabled unconditionally whenever
COMPILE_TEST is set.
This fixes both problems, by making the symbol user-visible
when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y.
As a side-effect, it is now possible to compile-test a Tegra
kernel with GPIO support disabled, which is harmless.

Properly track filter adds and deletes so the driver doesn't lose filters
during resets and up/down cycles. Add a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Implement a simple state machine so the driver can track the status of
each filter throughout its lifecycle. Properly manage the overflow promiscuous
state for the each VSI, and provide a way for the driver to detect when to exit
overflow promiscuous mode.
Remove all possible default MAC filters that the firmware may have set up so
that the driver can manage these correctly, particularly when VLANs come into
play. Remove the LAA flag for filters; instead just send whatever we get through
set_mac to the firmware as the LAA for wakeup purposes.
Finally, add the state of each filter to debugfs output so we can see what's
going on inside the driver's pointy little head.

When link is down, Advertised Link Modes was wrongly displaying full

====================
NFC 4.8 pull request
This is the first NFC pull request for 4.8. We have:
- A fairly large NFC digital stack patchset:
* RTOX fixes.
* Proper DEP RWT support.
* ACK and NACK PDUs handling fixes, in both initiator
and target modes.
* A few memory leak fixes.
- A conversion of the nfcsim driver to use the digital stack.
The driver supports the DEP protocol in both NFC-A and NFC-F.
- Error injection through debugfs for the nfcsim driver.
- Improvements to the port100 driver for the Sony USB chipset, in
particular to the command abort and cancellation code paths.
- A few minor fixes for the pn533, trf7970a and fdp drivers.

For consistency, and in order to hint at the synchronous nature of the
xdp_prog field, use READ_ONCE in the destroy path of the ring. All
occurrences should now use either READ_ONCE or xchg.

100GbE Intel Wired LAN Driver Updates 2016-07-20
This series contains updates to fm10k only.
Ngai-Mint provides a fix to clear PCIE_GMBX bits to ensure the proper
functioning of the mailbox global interrupt after a data path reset.
Jake provides most of the patches in the series, starting with a early
return from fm10k_down() if we are already down to prevent conflict with
other threads. Fixed an issue where fm10k_update_stats() could cause
a null pointer dereference, specifically if it is called when we are going
down and the rings have been removed. Cleans up and fixes the data path
reset flow, Tx hang routine and stop_hw(). Re-worked the fm10k_reinit()
to be more maintainable and fixed several inconsistencies with the work
flow. Implemented fm10k_prepare_suspend() and fm10k_handle_resume()
which abstract around the now existing fm10k_prepare_for_reset and
fm10k_handle_reset. The new functions also handle stopping the service
task, which is something that the original re-init flow does not need.
Fixed an issue where if an FLR occurs, VF devices will be knocked out of
bus master mode, and the driver will be unable to recover from the reset
properly, so ensure bus master is enabled after every reset. Fixed an
issue where a reset will occur as if for no reason, regularly every few
minutes until the switch manager software is loaded, which is caused
by continuously requesting the lport map so only do the request after
we have verified the switch mailbox is tx_ready.

Get rid of the last usage of the locked mv88e6xxx_reg_read function with
a new mv88e6xxx_port_read helper, useful later for chips with different

The 6352 family of switches and compatibles provide a 8-bit address and
16-bit data access to an optional EEPROM.
Newer chip such as the 6390 family slightly changed the access to 16-bit
address and 8-bit data.
This commit cleans up the EEPROM access code for 16-bit access and makes
it easy to eventually introduce future support for 8-bit access.
Here's a list of notable changes brought by this patch:
- provide Global2 unlocked helpers for EEPROM commands
- remove eeprom_mutex, only reg_lock is necessary for driver functions
- eeprom_len is 0 for chip without EEPROM, so return it directly
- the Running bit must be 0 before r/w, so wait for Busy *and* Running
- remove now unused mv88e6xxx_wait and mv88e6xxx_reg_write
- other than that, the logic (in _{get,set}_eeprom16) didn't change
Chips with an 8-bit EEPROM access will require to implement the
8-suffixed variant of G2 helpers and the related flag:
#define MV88E6XXX_FLAGS_EEPROM8 \
(MV88E6XXX_FLAG_G2_EEPROM_CMD | \
MV88E6XXX_FLAG_G2_EEPROM_ADDR)
