====================
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.

This patch allows to simulate the lost of frames exchanged between the 2
nfcsim devices through a control entry in the debugfs and is used as
follow:
echo n > /sys/kernel/debug/nfcsim/nfcX/dropframe
Where n specifies the number of frames to be dropped between 0 and 255
and nfcX is either nfc0 or nfc1, one of the two nfcsim devices.
In the following example, the next frame that should be sent by the nfc0
device will be dropped and thus not received by the nfc1 device:
echo 1 > /sys/kernel/debug/nfcsim/nfc0/dropframe
The value of 0 can be used to reset the dropframe counter.

The idea is to have a way to control and/or modify the behavior of the
nfcsim virtual devices.
This patch creates a folder tree in the debug filesystem. The debugfs is
usually mounted into /sys/kernel/debug and the nfcsim entries are
located in DEBUGFS/nfcsim/nfcX/ where X is either 0 or 1 depending on
the device you want to address.
These folders are empty for now and control entries will be added by
upcoming commits.

On mips and parisc:
drivers/bluetooth/btwilink.c: In function 'ti_st_open':
drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow]
hst->reg_status = -EINPROGRESS;
drivers/nfc/nfcwilink.c: In function 'nfcwilink_open':
drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow]
drv->st_register_cb_status = -EINPROGRESS;
There are actually two issues:
1. Whether "char" is signed or unsigned depends on the architecture.
As the completion callback data is used to pass a (negative) error
code, it should always be signed.
2. EINPROGRESS is 150 on mips, 245 on parisc.
Hence -EINPROGRESS doesn't fit in a signed 8-bit number.
Change the callback status from "char" to "int" to fix these.

The USB out_urb used to send commands to the device can be submitted
through the standard command processing queue coming from the Digital
Protocol layer but it can also be submitted from port100_abort_cmd().
To not submit the URB while already active, a mutex is now used to
protect it and a cmd_cancel flag is used to not send command while
canceling the previous one.

This patch ensures that a command is not still in process before sending
a new one to the device. This can happen when neard is in constant
polling mode: the configure_hw command can be sent when neard restarts
polling after a LLCP SYMM timeout but before the device has returned in
timeout from the last DEP frame sent.

With this complete rewrite, the loopback nfcsim driver now relies on the
Digital layer of the nfc stack. As with the previous version, 2 nfc
devices are declared when the driver is initialized. The driver supports
the NFC_DEP protocol in NFC-A and NFC-F technologies.
The 2 devices are using a pair of virtual links for sk_buff exchange.
The out-link of one device is the in-link of the other and conversely.
To receive data, a device calls nfcsim_link_recv_skb() on its in-link
and waits for incoming data on a wait queue. To send data, a device
calls nfcsim_link_send_skb() on its out-link which stores the passed skb
and signals its wait queue. If the peer device was in the
nfcsim_link_recv_skb() call, it will be signaled and will be able to
pass the received sk_buff up to the Digital layer.

When setting the driver framing as NFC_DIGITAL_FRAMING_NFCF_NFC_DEP it
used to be already configured as NFC_DIGITAL_FRAMING_NFCF which is the
same. So this entry was empty in the in_protocols table.
Now that the digital stack can handle PLS requests, it can be changed
on the fly from NFC_DIGITAL_FRAMING_NFCA_NFC_DEP.
This patch explicitly defines the framing configuration values for
NFC_DIGITAL_FRAMING_NFCF_NFC_DEP.

nfc_data_exchange => cb = rawsock_data_exchange_complete
ops->im_transceive = pn533_transceive => arg->cb = db

if_ops->send_frame_async
response:

queue_work(priv->wq, &priv->cmd_complete_work)
pn533_wq_cmd_complete
pn533_send_async_complete
cmd->complete_cb() = pn533_data_exchange_complete()
arg->cb() = rawsock_data_exchange_complete()
sock_put => socket refcnt-- => If the corresponding
socket gets closed in the meantime socket
will be destructed
sk_free
__sk_free
sk->sk_destruct = rawsock_destruct
nfc_deactivate_target
ops->deactivate_target = pn533_deactivate_target
pn533_send_cmd_sync
pn533_send_cmd_async
__pn533_send_async
list_add_tail(&cmd->queue,&dev->cmd_queue)
=> add to command list because
a command is currently
processed
wait_for_completion
=> the workqueue thread waits
here because it is the one
processing the commands
=> deadlock
To fix the deadlock pn533_deactivate_target is changed to
issue the PN533_CMD_IN_RELEASE command in async mode. This
way nothing blocks and the release command is executed after
the current command.

Currently it is not possible to only poll for passive targets
with the pn533 driver. To change this ATR_REQ is only sent when
NFC_PROTO_NFC_DEP is explicitly requested in poll_protocols.
As most implementations (e.g. neard) poll for all protocols
that are reported to be supported by the adapter, this should
not have much of an effect on current implementations.

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

Originally I only wanted to drop the unneeded inclusion of
<linux/i2c.h>, but then noticed that struct
microread_nfc_platform_data isn't actually used, and
MICROREAD_DRIVER_NAME is redefined in the only file where it is used,
so we can get rid of the header file and dead code altogether.

When pn544_hci_i2c_acpi_request_resources() gets called we
already know that the entries in ->acpi_match_table have
matched ACPI ID of the device.
In addition I2C client pointer cannot be NULL in any case
(otherwise I2C core would not call ->probe() for the driver
in the first place).
Drop the two useless checks from the driver.

It is cleaner to check if the i2c_client irq is not configured
properly before allocating any data.
