Larry Finger 06f34572c6 rtlwifi: rtl8188ee: Fix module parameter initialization
In this driver, parameters disable_watchdog and sw_crypto are never
copied into the locations used in the main code. While modifying the
parameter handling, the copying of parameter msi_support is moved to
be with the rest.

Larry Finger 78bae1de42 rtlwifi: rtl8821ae: Fix errors in parameter initialization
This driver failed to copy parameters sw_crypto and disable_watchdog into
the locations actually used by the driver. In addition, msi_support was
initialized three times and one of them used the wrong variable. The
initialization of parameter int_clear was moved so that it is near that
of the rest of the parameters.

Larry Finger 793b099942 rtlwifi: rtl8723ae: Fix initialization of module parameters
This driver has some errors in the handling of module parameters. These
include missing initialization for parameters msi_support and
disable_watchdog. In addition, neither of these parameters nor sw_crypto
are transferred into the locations used by the driver. A final fix is
adding parameter msi to the module named and description macros.

Larry Finger 7079604ddb rtlwifi: rtl8723be: Fix module parameter initialization
This driver has a number of errors in the module initialization. These
include the following:

Parameter msi_support is stored in two places - one is removed.
Paramters sw_crypto and disable_watchdog were never stored in the final
locations, nor were they initialized properly.

chunfan chen 84a38fb316 mwifiex: fix WPA connection problem
Device fails to connect to some AP's configured in WPA
security mode. Currently IE buffer parsing logic in driver
expects WPA IE to be present at the beginning of IE buffer.
Otherwise connection is failed with 'incompatible network
setting' error.

This patch fixes the problem by improving IE buffer parsing
logic.

In order to let the fw do offloading properly, we need

Configure the params on d0i3 entrance, and update them

Since d3 code is now called in d0i3 which requires runtime
pm only, make d3.0 depend on CONFIG_PM (rather than
CONFIG_PM_SLEEP), and add required #ifdefs and wrappers
where needed, so both CONFIG_PM=n and CONFIG_PM_RUNTIME=n

Emmanuel Grumbach 6eb5e529d7 iwlwifi: pcie: build an A-MSDU using TSO core
When the op_mode sends an skb whose payload is bigger than
MSS, PCIe will create an A-MSDU out of it. PCIe assumes
that the skb that is coming from the op_mode can fit in one
A-MSDU. It is the op_mode's responsibility to make sure
that this guarantee holds.

Additional headers need to be built for the subframes.
The TSO core code takes care of the IP / TCP headers and
the driver takes care of the 802.11 subframe headers.

These headers are stored on a per-cpu page that is re-used
for all the packets handled on that same CPU. Each skb
holds a reference to that page and releases the page when
it is reclaimed. When the page gets full, it is released
and a new one is allocated.

Since any SKB that doesn't go through the fast-xmit path
of mac80211 will be segmented, we can assume here that the
packet is not WEP / TKIP and has a proper SNAP header.

Sara Sharon c97dab4079 iwlwifi: mvm: change protocol offload flows
RFC4862 states that "In all cases, a node MUST NOT respond to
a Neighbor Solicitation for a tentative address".
Currently the driver configures the NS offload and does not wait
for address to become permanent, thus violating the RFC.
Just removing the address from the address list is not good enough
for all cases, since the NS messages are needed for the duplicate
address detection and should not be discarded.

For d0i3 disable NS offload. Put tentative address in the address
list so the NS packet will not be filtered out by ucode.
For D3 the platform will not wake from NS packets - so enable
NS offload while removing the tentative address from the list.

Given that now NS offload might be disabled, and that the ucode
uses the IP data for other puroposes (L3 filtering) add two
independent flags indicating if IPv4\IPv6 data is valid.

Golan Ben-Ami e6eb8ca9e4 iwlwifi: expose fw usniffer mode to more utilities
Today, in order to configure fw in usniffer mode, the ucode
must have the corresponding tlv, which is revealed to the driver
while parsing the ucode.

Expose the mode of the usniffer to other utilities in the driver
(other than the ucode parser) by passing back a pointer to the value.
This can be very useful for allowing configuring the fw dbg data
using an external configuration file, because this configuration
depends on the fw usniffer mode.

Luca Coelho b7282643bf iwlwifi: replace d0i3_mode and wowlan_d0i3 with more generic variables
The d0i3_mode variable is used to distinguish between transports that
handle d0i3 entry during suspend by themselves (i.e. the slave
transports) and those which rely on the op_mode layer to do it.  The
reason why the former do it by themselves is that they need to
transition from d0i3 in runtime_suspend into d0i3 in system-wide
suspend and this transition needs to happen before the op_mode's
suspend flow is called.

The wowlan_d0i3 element is also a bit confusing, because it just
reflects the wowlan->any value for the trans to understand.  This is a
bit unclear in the code and not generic enough for future use.

To make it clearer and to generalize the platform power mode settings,
introduce two variables to indicate the platform power management
modes used by the transport.

Additionally, in order not to take too big a step in one patch, treat
this new variables semantically in the same way as the old d0i3_mode
element, introducing a iwl_mvm_enter_d0i3_on_suspend() function to
help with that.

This commit also adds the foundation for a new concept where the
firmware configuration state (i.e. D0, D3 or D0i3) is abstracted from
the platform PM mode we are in (i.e. runtime suspend or system-wide
suspend).

Miaoqing Pan ed14dc0af7 ath9k: feeding entropy in kernel from ADC capture
This patch is derived from
commit 6301566e0b ("ath9k: export HW random number generator"),

We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x,
and AR9340, and it has sufficient quality random data (at least 10 bits
and up to 22 bits of min-entropy for a 32-bit value). We conservatively
assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE
is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up
the pool as soon as the entropy counter becomes 896/4096 (set by random.c).
Since ADC was not designed to be a dedicated HW RNG, we do not want to bind
it to /dev/hwrng framework directly. This patch feeds the entropy directly
from the WiFi driver to the input pool. The ADC register output is only
used as a seed for the Linux entropy pool. No conditioning is needed,
since all the conditioning is performed by the pool itself.

Kosuke Tatsukawa a7decc44a0 brcmfmac: fix waitqueue_active without memory barrier in brcmfmac driver
brcmf_msgbuf_ioctl_resp_wake() seems to be missing a memory barrier
which might cause the waker to not notice the waiter and miss sending a
wake_up as in the following figure.

  brcmf_msgbuf_ioctl_resp_wake		    brcmf_msgbuf_ioctl_resp_wait
------------------------------------------------------------------------
if (waitqueue_active(&msgbuf->ioctl_resp_wait))
/* The CPU might reorder the test for
   the waitqueue up here, before
   prior writes complete */
   	   	     	 	       /* wait_event_timeout */
				        /* __wait_event_timeout */
					 /* ___wait_event */
					 prepare_to_wait_event(&wq, &__wait,
					   state);
					 if (msgbuf->ctl_completed)
					 ...
msgbuf->ctl_completed = true;
					 schedule_timeout(__ret))
------------------------------------------------------------------------

There are three other place in drivers/net/wireless/brcm80211/brcmfmac/
which have similar code.  The attached patch removes the call to
waitqueue_active() leaving just wake_up() behind.  This fixes the
problem because the call to spin_lock_irqsave() in wake_up() will be an
ACQUIRE operation.

I found this issue when I was looking through the linux source code
for places calling waitqueue_active() before wake_up*(), but without
preceding memory barriers, after sending a patch to fix a similar
issue in drivers/tty/n_tty.c  (Details about the original issue can be
found here: https://lkml.org/lkml/2015/9/28/849).

Arnd Bergmann 31ced24d88 iwlegacy: mark il_adjust_beacon_interval as noinline
With the new optimized do_div() code, some versions of gcc
produce obviously incorrect code that leads to a link error
in iwlegacy/common.o:

drivers/built-in.o: In function `il_send_rxon_timing':
:(.text+0xa6b4d4): undefined reference to `____ilog2_NaN'
:(.text+0xa6b4f0): undefined reference to `__aeabi_uldivmod'

In a few thousand randconfig builds, I have seen this problem
a couple of times in this file, but never anywhere else in the
kernel, so we can try to work around this in the only file
that shows the behavior, by marking the il_adjust_beacon_interval
function as noinline, which convinces gcc to use the unoptimized
do_div() all the time.

While we wait for the completion of the previous command, system suspend

Martin Blumenstingl 6fa658fd5a ath9k: Simplify and fix eeprom endianness swapping
The three eeprom implementations had quite some duplicate code when it
came to endianness swapping.
Additionally there was a bug in eeprom_4k and eeprom_9287 which
prevented the endianness swapping from working correctly, because the
swapping code was guarded within an "if (!ath9k_hw_use_flash(ah))". In
eeprom_def this check did not exist, so it seems that eeprom_def was the
only implementation where endianness swapping worked.

This patch takes the duplicate code and moves it from eeprom_* to
eeprom.c. The new code is derived from eeprom_def, while taking into
account the specifics from the other implementations.

since we are not really doing anything.  The reference is only needed
when the mac80211 start op (or a hw restart) is running, to prevent
going into runtime or system supend in the meantime.  This will allow

Matti Gottlieb dc28e12f21 iwlwifi: mvm: ROC: Extend the ROC max delay duration & limit ROC duration
When associated to an AP and a ROC event with a long duration is scheduled
the FW may have a hard time scheduling a consecutive time event, since it
has to remain on the connection channel to hear the AP's DTIM.
In addition, when associated and a ROC is requested with a duration
greater than the DTIM interval, the FW will not be able to schedule
the ROC event, since it needs to wake up for the DTIM.

Increasing the "max delay" duration to the DTIM period will allow the FW to
wait until after the DTIM and then schedule the ROC time event.
Limiting the ROC to be less than the DTIM interval will assure that the
time event will be scheduled for at least part of the time (instead of
automatically failing)

Extend the ROC max delay duration to min(dtim_interval * 3, 600TU),
and limit the duration to be less than the DTIM interval.

value returned by iwl_mvm_scan_stop() for scheduled scans and falling
thorugh to the next case, which caused us to always return zero.
