====================
wireless-drivers fixes for 4.12
Two important fixes for brcmfmac. The rest of the brcmfmac patches are
either code preparation and fixing a new build warning.
brcmfmac
* fix a NULL pointer dereference during resume
* fix a NULL pointer dereference with USB devices, a regression from
v4.12-rc1

USB devices rely on queuing functionality provided by the fwsignal
module regardless the mode fwsignal is operating in. For this some
data structure needs to be reserved which is tied to the interface,
which is done by brcmf_fws_add_interface(). However, it checks the
mode. Replace that by checking result from brcmf_fws_queue_skbs().
Otherwise the driver will crash in a null pointer dereference when
data is transmitted on the interface.

When request firmware fails, brcmf_ops_sdio_remove is being called and
brcmf_bus freed. In such circumstancies if you do a suspend/resume cycle
the kernel hangs on resume due a NULL pointer dereference in resume
function. So in brcmf_sdio_firmware_callback() we need to unbind the
driver from both sdio_func devices when firmware load failure is indicated.

When firmware loading failed the code used to unbind the device provided
by the calling code. However, for the sdio driver two devices are bound
and both need to be released upon failure. The callback has been extended
with parameter to pass error code so add that in this commit upon firmware
loading failure.

Extend the parameters in the firmware callback so it can be called
upon success and failure. This allows the caller to properly clear
all resources in the failure path. Right now the error code is
always zero, ie. success.

Network devices can allocate reasources and private memory using
netdev_ops->ndo_init(). However, the release of these resources
can occur in one of two different places.
Either netdev_ops->ndo_uninit() or netdev->destructor().
The decision of which operation frees the resources depends upon
whether it is necessary for all netdev refs to be released before it
is safe to perform the freeing.
netdev_ops->ndo_uninit() presumably can occur right after the
NETDEV_UNREGISTER notifier completes and the unicast and multicast
address lists are flushed.
netdev->destructor(), on the other hand, does not run until the
netdev references all go away.
Further complicating the situation is that netdev->destructor()
almost universally does also a free_netdev().
This creates a problem for the logic in register_netdevice().
Because all callers of register_netdevice() manage the freeing
of the netdev, and invoke free_netdev(dev) if register_netdevice()
fails.
If netdev_ops->ndo_init() succeeds, but something else fails inside
of register_netdevice(), it does call ndo_ops->ndo_uninit(). But
it is not able to invoke netdev->destructor().
This is because netdev->destructor() will do a free_netdev() and
then the caller of register_netdevice() will do the same.
However, this means that the resources that would normally be released
by netdev->destructor() will not be.
Over the years drivers have added local hacks to deal with this, by
invoking their destructor parts by hand when register_netdevice()
fails.
Many drivers do not try to deal with this, and instead we have leaks.
Let's close this hole by formalizing the distinction between what
private things need to be freed up by netdev->destructor() and whether
the driver needs unregister_netdevice() to perform the free_netdev().
netdev->priv_destructor() performs all actions to free up the private
resources that used to be freed by netdev->destructor(), except for
free_netdev().
netdev->needs_free_netdev is a boolean that indicates whether
free_netdev() should be done at the end of unregister_netdevice().
Now, register_netdevice() can sanely release all resources after
ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit()
and netdev->priv_destructor().
And at the end of unregister_netdevice(), we invoke
netdev->priv_destructor() and optionally call free_netdev().

When we want to stop the recording of the firmware debug
and restart it later without reloading the firmware we
don't need to resend the configuration that comes with
host commands.
Sending those commands confused the hardware and led to
an NMI 0x66.
Change the flow as following:
* read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL)
* clear those registers
* wait for the hardware to complete its write to the buffer
* get the data
* restore the value of those registers (to restart the
recording)
For early start (where the configuration is already
compiled in the firmware), we don't need to set those
registers after the firmware has been loaded, but only
when we want to restart the recording without having
restarted the firmware.

Up until now, the driver was comparing the rate reported by the FW and
the rate of the latest LQ command to avoid processing data belonging
to the old LQ command. Recently, FW changed the meaning of the initial
rate field in tx response and it holds the actual rate (which is not
necessarily the initial rate of LQ's rate table). Use instead LQ cmd
color to be able to filter out tx responses/BA notifications which
where sent during earlier LQ commands' time frame.
This fixes some throughput degradation in noisy environments.

For SDIO the alignment requirement for transfers from device to host
is configured in firmware. This configuration is limited to minimum
of 4-byte alignment. However, this is not correct for platforms using
64-bit DMA when the minimum alignment should be 8 bytes. This issue
appeared when the ALIGNMENT definition was set according the DMA
configuration. The configuration in firmware was not using that macro
defintion, but a hardcoded value of 4. Hence the driver reported
alignment failures for data coming from the device and causing
transfers to fail.

The SMD channel is not the primary WCNSS channel and must explicitly be
closed as the device is removed, or the channel will already by open on
a subsequent probe call in e.g. the case of reloading the kernel module.
This issue was introduced because I simplified the underlying SMD
implementation while the SMD adaptions of the driver sat on the mailing
list, but missed to update these patches. The patch does however only
apply back to the transition to rpmsg, hence the limited Fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull hw lockdown support from David Howells:
"Annotation of module parameters that configure hardware resources
including ioports, iomem addresses, irq lines and dma channels.
This allows a future patch to prohibit the use of such module
parameters to prevent that hardware from being abused to gain access
to the running kernel image as part of locking the kernel down under
UEFI secure boot conditions.
Annotations are made by changing:
module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)
to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

For multiple scheduled scan support the driver needs to know which
scheduled scan request is being stopped. Pass the request id in the
.sched_scan_stop() callback.

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

One more pull-request intended for 4.12. These are the changes:
* The firmware for 7265D and 3168 NICs is frozen at version 29;
* Sari continues working heavily on support for A000 series;
* A bunch of fixes;
* Some cleanups here and there;

The driver was making changes to the skb_header without
ensuring it was writable (i.e. uncloned).
This patch also removes some boiler plate header size
checking/adjustment code as that is also handled by the
skb_cow_header function used to make header writable.

In a000 devices we will get all nvm data from the firmware,
and can save most of the parsing.
Export two APIs that op mode will still use.
Adjust API of init_sbands to be independent of NVM file structure
so it can be used by op mode as well.

When applying no-reclaim logic to commands other than the group
zero for legacy commands, commands such as 0x1c (TX_CMD in group
0) can't be used in any other group. Fix that by applying this
logic only for group 0 - it's not and should never be needed for
any other groups.

Support change to ADD_STA API to support station types.
Each station is assigned its type.
This simplifies FW handling of the broadcast and multicast
stations:
* broadcast station is identified by its type and not the mac
address.
* multicast queue is no longer treated differently. The opening
and closing of it is done by referring to its station.
There is no need to specify it in the MAC command.
* When disabling TX to all station driver can disable the traffic
on multicast station, so FW doesn't have to do it.
Change is backward compatible.
Change the order of adding and removing the stations according to
FW requirements.

Most of the fields aren't needed in new TX path.
Enlarging the struct to 512 queues will consume a lot of memory.
Remove all references to the struct in the new TX path.
Move mac80211 queue mapping outside, since it will be needed per
queue for TVQM mode.
Add warning in paths that shouldn't be hit.

When CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, iwlwifi crashes
when the opmode module cannot be loaded, due to completing
the completion before using drv->dev, which can then already
be freed.
Fix this by removing the (fairly useless) message. Moving the
completion later causes a deadlock instead, so that's not an
option.

If we fail to allocate the small chunk of memory for the
pieces of the firmware file, we leak the whole firmware
image instead...
Since the allocation failure is really unlikely, just bail
out at that point instead.

actually have been) use it for various reasons.
