Ganapathi Bhat a5b60de697 mwifiex: Avoid skipping WEP key deletion for AP
This patch fixes the issue specific to AP. AP is started with WEP
security and external station is connected to it. Data path works
in this case. Now if AP is restarted with WPA/WPA2 security,
station is able to connect but ping fails.

Driver skips the deletion of WEP keys if interface type is AP.
Removing that redundant check resolves the issue.

As reported by Felix:

Though protected by an ifdef, introducing an usb symbol dependency in
the rt2x00lib module is a major inconvenience for distributions that
package kernel modules split into individual packages.

Get rid of this unnecessary dependency by calling the usb related

Johannes Berg 23aeea943b iwlwifi: pcie: fix another RF-kill race
When resuming, it's possible for the following scenario to occur:

 * iwl_pci_resume() enables the RF-kill interrupt
 * iwl_pci_resume() reads the RF-kill state (e.g. to 'radio enabled')
 * RF_KILL interrupt triggers, and iwl_pcie_irq_handler() reads the
   state, now 'radio disabled', and acquires the &trans_pcie->mutex.
 * iwl_pcie_irq_handler() further calls iwl_trans_pcie_rf_kill() to
   indicate to the higher layers that the radio is now disabled (and
   stops the device while at it)
 * iwl_pcie_irq_handler() drops the mutex
 * iwl_pci_resume() continues, acquires the mutex and calls the higher
   layers to indicate that the radio is enabled.

At this point, the device is stopped but the higher layers think it's
available, and can call deeply into the driver to try to enable it.
However, this will fail since the device is actually disabled.

Sara Sharon 94c3e614df iwlwifi: mvm: fix pending frame counter calculation
In DQA mode the check whether to decrement the pending frames
counter relies on the tid status and not on the txq id.
This may result in an inconsistent state of the pending frames
counter in case frame is queued on a non aggregation queue but
with this TID, and will be followed by a failure to remove the
station and later on SYSASSERT 0x3421 when trying to remove the
MAC.
Such frames are for example bar and qos NDPs.
Fix it by aligning the condition of incrementing the counter
with the condition of decrementing it - rely on TID state for
DQA mode.
Also, avoid internal error like this affecting station removal
for DQA mode - since we can know for sure it is an internal
error.

A few of the static queues are enabled along with the bcast

This is needed because we sometimes have a STA being removed

different one). If we wait for the mac ctxt release we will
try to allocate the queues again (as this is currently done
in the STA allocation and not in the MAC init) although
they weren't freed, and even if the sta_id of the STA has

Johannes Berg 05e5a7e58d iwlwifi: mvm/pcie: adjust A-MSDU tx_cmd length in PCIe
Instead of setting the tx_cmd length in the mvm code, which is
complicated by the fact that DQA may want to temporarily store
the SKB on the side, adjust the length in the PCIe code which
also knows about this since it's responsible for duplicating
all those headers that are account for in this code.

As the PCIe code already relies on the tx_cmd->len field, this
doesn't really introduce any new dependencies.

To make this possible we need to move the memcpy() of the TX
command until after it was updated.

This does even simplify the code though, since the PCIe code
already does a lot of manipulations to build A-MSDUs correctly
and changing the length becomes a simple operation to see how
much was added/removed, rather than predicting it.

Sara Sharon 1f37065083 iwlwifi: mvm: support unification of INIT and RT images
For a000 devices the INIT and RT images are unified to one
image.
The changes in the flow are the following:
* Driver load only RT firmware - meaning that the nvm access
  command will be done in the RT image load flow.
* A new command (NVM_ACCESS_COMPLETE) now signals to the FW that
  the driver is done accessing the NVM and FW can proceed with phy
  calibrations.
* Phy DB is no longer sent from INIT FW to be restored by driver
  for the RT FW - all the phy DB is now internal to the FW.
  INIT complete will now follow the NVM access command, without
  phy DB calls before.
* Paging command is sent earlier in the flow before NVM access
  to enable a complete load of FW.
* caution must be care when restart is called since we may have
  not completed init flow even though we are in RT firmware.

introduce a new flag clk_is_20mhz in struct hw_mode_spec to make the

Waldemar Rymarkiewicz f2593cb1b2 ath10k: Search SMBIOS for OEM board file extension
Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified, among others, by device and sybsystem ids.

The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.

To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name
Extension to specify the extension/variant name. The driver will take the
extension suffix into consideration and will load the right (non-default)
board data file if necessary.

If it is unnecessary to use extension board data file, please leave the
SMBIOS field blank and default configuration will be used.

Example:
If a default board data file for a specific board is identified by a string
      "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
       subsystem-device=0310"
then the OEM specific data file, if used, could be identified by variant
suffix:
      "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
       subsystem-device=0310,variant=DE_1AB"

structure to wait for a reply.
In some scenarios, complete was called twice on the
completion structure. This happened mainly with a disconnect
event which can arrive both unsolicited and as a reply to
a disconnect request. In this case the completion structure
was left marked as "done" and the next wmi_call returned
immediately with a corrupted reply buffer. This caused
unexpected results including crashes.
Fix this by adding the missing call to reinit_completion.

Dedy Lansky 849a564b7e wil6210: add disable_ap_sme module parameter
By default, AP SME is handled by driver/FW.
In case disable_ap_sme is true, driver doesn't turn-on
WIPHY_FLAG_HAVE_AP_SME and the responsibility for
AP SME is passed to user space.

With AP SME disabled, driver reports assoc request frame
to user space which is then responsible for sending assoc
response frame and for sending NL80211_CMD_NEW_STATION.
Driver also reports disassoc frame to user space
which should then send NL80211_CMD_DEL_STATION.

NL80211_CMD_SET_STATION with NL80211_STA_FLAG_AUTHORIZED
is used by user space to allow/disallow data transmit.

Larry Finger 106e0deca1 rtlwifi: rtl8192cu: Convert driver to use common macros
These drivers use a set of complicated macros to extract and insert
information for the RX and TX descriptors. Driver rtl8192cu had a
different set than was used for the PCI-based drivers. To simplify
the code, rtl8192cu is switched to use the common version. In the
process, two errors in those common macros were found and fixed.

Besides simplifying the code, there is an additional benefit. We have
no BE hardware to test the PCI driver, but using the common macros
provides an additional test for the validity of many endian-sensitive
operations.

Larry Finger 89d32c9071 rtlwifi: Download firmware as bytes rather than as dwords
The firmware is read from disk as a little-endian byte string. The code
that loads the firmware into the device transfers it as 4-byte quantities.
The routines that write multi-byte quantities on BE hardware assume that
the data are in CPU order, and automatically do the conversion to the LE
order required by the device. As a result, the firmware is transmitted
incorrectly. Rather than do multiple byte swaps on the data, the download
routine is revised to transmit bytes rather than dwords. Although the
number of I/O operations is increased, the firmware is not often loaded.

All drivers have the same bug, and use essentially the same code to
download firmware. These routines have been moved into rtlwifi.

Some CamelCase variables have been renamed.

Functions brcmf_c_prec_enq and brcmf_sdio_init don't exist so we
really don't need their declarations. Function brcmf_parse_tlvs is used
in cfg80211.c only so make it static and drop from header as well.

Gavin Li 8e290cecdd brcmfmac: fix incorrect event channel deduction
brcmf_sdio_fromevntchan() was being called on the the data frame
rather than the software header, causing some frames to be
mischaracterized as on the event channel rather than the data channel.

This fixes a major performance regression (due to dropped packets). With
this patch the download speed jumped from 1Mbit/s back up to 40MBit/s due
to the sheer amount of packets being incorrectly processed.

BCM43455 is a more recent revision of the BCM4345. Some of the BCM43455
got a dedicated SDIO device ID which is currently not supported by
brcmfmac.
Adding the new sdio_device_id to brcmfmac is enough to get the BCM43455
supported because the chip itself is already supported (due to BCM4345
support in the driver).

Brian Norris 0ed917d09d mwifiex: don't complain about 'unknown event id: 0x63'
Marvell folks tell me this is a debugging event that the driver doesn't
need to handle, but on 8997 w/ firmware 16.68.1.p97, I see several of
these sorts of messages at (for instance) boot time:

[   13.825848] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63
[   14.838561] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63

[   32.529923] mwifiex_pcie 0000:01:00.0: event: unknown event id: 0x63

Let's handle this "event" with a much lower verbosity.

Brian Norris fe11678839 mwifiex: pcie: read FROMDEVICE DMA-able memory with READ_ONCE()
In mwifiex_delay_for_sleep_cookie(), we're looping and waiting for the
PCIe endpoint to write a magic value back to memory, to signal that it
has finished going to sleep. We're not letting the compiler know that
this might change underneath our feet though. Let's do that, for good
hygiene.

I'm not aware of this fixing any concrete problems. I also give no
guarantee that this loop is actually correct in any other way, but at
least this looks like an improvement to me.

Brian Norris 5d5ddb5e0d mwifiex: pcie: don't loop/retry interrupt status checks
The following sequence occurs when using IEEE power-save on 8997:
(a) driver sees SLEEP event
(b) driver issues SLEEP CONFIRM
(c) driver recevies CMD interrupt; within the interrupt processing loop,
    we do (d) and (e):
(d) wait for FW sleep cookie (and often time out; it takes a while), FW
    is putting card into low power mode
(e) re-check PCIE_HOST_INT_STATUS register; quit loop with 0 value

But at (e), no one actually signaled an interrupt (i.e., we didn't check
adapter->int_status). And what's more, because the card is going to
sleep, this register read appears to take a very long time in some cases
-- 3 milliseconds in my case!

Now, I propose that (e) is completely unnecessary. If there were any
additional interrupts signaled after the start of this loop, then the
interrupt handler would have set adapter->int_status to non-zero and
queued more work for the main loop -- and we'd catch it on the next
iteration of the main loop.

So this patch drops all the looping/re-reading of PCIE_HOST_INT_STATUS,
which avoids the problematic (and slow) register read in step (e).

Incidentally, this is a very similar issue to the one fixed in commit
ec815dd2a5 ("mwifiex: prevent register accesses after host is
sleeping"), except that the register read is just very slow instead of
fatal in this case.

Tested on 8997 in both MSI and (though not technically supported at the
moment) MSI-X mode.

Brian Norris 062e008a6e mwifiex: pcie: use posted write to wake up firmware
Depending on system factors (e.g., the PCIe link PM state), the first
read to wake up the Wifi firmware can take a long time. There is no
reason to use a (blocking, non-posted) read at this point, so let's just
use a write instead. Write vs. read doesn't matter functionality-wise --
it's just a dummy operation. But let's make sure to re-write with the
correct "ready" signature, since we check for that in other parts of the
driver.

This has been shown to decrease the time spent blocking in this function
on RK3399.

Not clearing the previous tx bit rate status
results in a ambigous tx bit rate reporting to
mac80211/cfg80211, for example the previous bit
rate status would have been marked as legacy rate
, while the current rate would have been an HT/VHT
rate with the tx bit rate flags set and this results
in exporting tx bitrate as legacy rate but with HT/VHT
rate flags set, fix this by clearing the tx bitrate
status for each event. This also fixes the below

Michal Kazior 0a744d9274 ath10k: prevent sta pointer rcu violation
Station pointers are RCU protected so driver must
be extra careful if it tries to store them
internally for later use outside of the RCU
section it obtained it in.

It was possible for station teardown to race with
some htt events. The possible outcome could be a
use-after-free and a crash.

Only peer-flow-control capable firmware was
affected (so hardware-wise qca99x0 and qca4019).

This could be done in sta_state() itself via
explicit synchronize_net() call but there's
already a convenient sta_pre_rcu_remove() op that
can be hooked up to avoid extra rcu stall.

The peer->sta pointer itself can't be set to
NULL/ERR_PTR because it is later used in
sta_state() for extra sanity checks.

Brian Norris 6183468a23 mwifiex: debugfs: Fix (sometimes) off-by-1 SSID print
Similar to commit fcd2042e8d ("mwifiex: printk() overflow with 32-byte
SSIDs"), we failed to account for the existence of 32-char SSIDs in our
debugfs code. Unlike in that case though, we zeroed out the containing
struct first, and I'm pretty sure we're guaranteed to have some padding
after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes
long).

So, this is the difference between:

  # cat /sys/kernel/debug/mwifiex/mlan0/info
  ...
  essid="0123456789abcdef0123456789abcdef "
  ...

and the correct output:

  # cat /sys/kernel/debug/mwifiex/mlan0/info
  ...
  essid="0123456789abcdef0123456789abcdef"
  ...

Fixes: 5e6e3a92b9 ("wireless: mwifiex: initial commit for Marvell mwifiex driver")

Rafał Miłecki ab99063f87 brcmfmac: setup wiphy bands after registering it first
During bands setup we disable all channels that firmware doesn't support
in the current regulatory setup. If we do this before wiphy_register
it will result in copying set flags (including IEEE80211_CHAN_DISABLED)
to the orig_flags which is supposed to be persistent. We don't want this
as regulatory change may result in enabling some channels. We shouldn't
mess with orig_flags then (by changing them or ignoring them) so it's
better to just take care of their proper values.

This patch cleanups code a bit (by taking orig_flags more seriously) and
allows further improvements like disabling really unavailable channels.
We will need that e.g. if some frequencies should be disabled for good
due to hardware setup (design).

Rafał Miłecki 9ea0c30760 brcmfmac: don't preset all channels as disabled
During init we take care of regulatory stuff by disabling all
unavailable channels (see brcmf_construct_chaninfo) so this predisabling
them is not really required (and this patch won't change any behavior).
It will on the other hand allow more detailed runtime control over
channels which is the main reason for this change.

Stanislaw Gruszka 1701221696 rt2800usb: mark tx failure on timeout
If we do not get TX status in reasonable time, we most likely fail to
send frame hence mark it as so.

Stanislaw Gruszka e4019e7f95 rt2800: tune TX_RTS_CFG config
Enable RTS frame retry fall-back and limit number of RTS retries to 7
what is default number of retries for small frames. As RTS/CTS is used
for TXOP protection, those settings prevent posting lots of RTS
frames when remote station do not response with CTS at the moment. After
sending 7 RTS's the HW will start back-off mechanism and after it will
start posing RTS again to get access to the medium.
