Mika Westerberg 8975842bed brcmfmac: Do not crash if platform data is not populated
The driver looks for pdata->oob_irq_supported to find out if wowl can be
supported. However, not all platforms populate pdata in which case we crash
the kernel because of NULL pointer dereference.

Fixes: 330b4e4be9 ("brcmfmac: Add wowl support for SDIO devices.")

Paul Bolle dddd60220f ipw2200: select CFG80211_WEXT
Commit 24a0aa212e ("cfg80211: make WEXT compatibility unselectable")
made it impossible to depend on CFG80211_WEXT. It does still allow to
select that symbol. (Yes, the commit summary is confusing.)

So make IPW2200 select CFG80211_WEXT, so that the ipw2200 driver can be
enabled in config again.

Brian Norris 1d240d3702 brcmsmac: don't leak kernel memory via printk()
Debug code prints the fifo name via custom dev_warn() wrappers. The
fifo_names array is only non-zero when debugging is manually enabled,
which is all well and good. However, it's *not* good that this array
uses zero-length arrays in the non-debug case, and so it doesn't
actually have any memory allocated to it. This means that as far as we
know, fifo_names[i] actually points to garbage memory.

I've seen this in my log:

[ 4601.205511] brcmsmac bcma0:1: wl0: brcms_c_d11hdrs_mac80211: �GeL txop exceeded phylen 137/256 dur 1602/1504

So let's give this array space enough to fill it with a NULL byte.

Emmanuel Grumbach 03d6c3b0fa iwlwifi: pcie: re-ACK all interrupts after device reset
When we reset the device, the CSR_INT gets cleared as well
as CSR_INT_MASK. Meaning that we shouldn't get any interrupt
but, due to a hardware bug, recent devices will keep sending
interrupts. This leads to an interrupt storm while stopping
the device.
The way to fix this is to ACK all the interrupts after the
device is reset so that the value of CSR_INT will stay
0xffffffff.

Avinash Patil dda9ddeb26 mwifiex: do not delete station entries in del_sta handler
A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.

This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

Until this patch, dumping the monitor data could be done only

allows to pull the monitor data also on other families, and
also to pull the monitor data if an internal buffer is used.

Emmanuel Grumbach 5a12a07e44 iwlwifi: dvm: fix flush support for old firmware
Since the commit below, iwldvm sends the FLUSH command to
the firmware. All the devices that use iwldvm have a
firmware that expects the _v3 version of this command,
besides 5150.
5150's latest available firmware still expects a _v2 version
of the FLUSH command.
This means that since the commit below, we had a mismatch for
this specific device only.
This mismatch led to the NMI below:

In 8000 B-step the FW file has changed, but by the time we
know the HW step, the FW file is already requested.

This patch defaults 8000 family to B-step if no HW step is

really is (in 8000 family) and if it isn't B-step, the FW
file is released and the A-step file is requested.

If card reset with firmware download executed, followed by reset
with use of firmware from build in flash, firmware download indication
remains in the hardware register.
When running firmware download flow,
the SW download indication is written by the driver to bit 0 in usage_6:
wil_fw_load(), "S(RGF_USER_USAGE_6, 1);"
This register, like all USER RGF, wasn't reset in SW reset flow.
Therefore the driver must clear it on SW reset flow.

In the wil_tx_ring, error message printed when tx attempted
while vring has no space to accommodate all fragments of frame.
Normally, such situation handled by stopping tx queue.
But, if tx queue is by-passed (like pktgen does), this error
will be triggered at high rate and dmesg will be flooded with
this message. Whole system may become unstable and hang with
no possible recover except power cycle.

Rate-limit it to prevent dmesg flooding.
