[PATCH 00/20] iwlwifi: updates intended for v5.3 2019-06-28

[Luca Coelho]

From: Luca Coelho <luciano.coelho@intel.com>

Hi,

Here's the second set of patches intended for v5.3.  It's the usual
development, new features, cleanups and bugfixes.

The changes are:

* Special SAR implementation for South Korea;
* Fixes in the module init error paths;
* Debugging infra work continues;
* A few clean-ups;
* Other small fixes and improvements;

As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.

Please review.

Cheers,
Luca.

[PATCH 01/20] iwlwifi: lib: Use struct_size() helper

[Luca Coelho]

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, change the following form:

sizeof(*pattern_cmd) +
               wowlan->n_patterns * sizeof(struct iwlagn_wowlan_pattern)

 to :

struct_size(pattern_cmd, patterns, wowlan->n_patterns)

This code was detected with the help of Coccinelle.

[PATCH 03/20] iwlwifi: remove some unnecessary NULL checks

[Luca Coelho]

From: Dan Carpenter <dan.carpenter@oracle.com>

These pointers are an offset into the "sta" struct.  They're assigned
like this:

	const struct ieee80211_sta_vht_cap *vht_cap = &sta->vht_cap;

They're not the first member of the struct (->supp_rates[] is first) so
they can't be NULL.

[PATCH 04/20] iwlwifi: mvm: correctly fill the ac array in the iwl_mac_ctx_cmd

[Luca Coelho]

From: Naftali Goldstein <naftali.goldstein@intel.com>

The indexes into the ac array in the iwl_mac_ctx_cmd are from the iwl_ac
enum and not the txfs.  The current code therefore puts the edca params
in the wrong indexes of the array, causing wrong priority for
data-streams of different ACs.
Fix this.

Note that this bug only occurs in NICs that use the new tx api, since in
the old tx api the txf number is equal to the corresponding ac in the
iwl_ac enum.

Currently, WGDS SAR offset group 3 is not used (not mapped to any country).
In order to be able to comply with South Korea new restriction:
- OEM will use WGDS SAR offset group 3 to South Korea limitation.
- OEM will change WGDS revision to 1 (currently latest revision is 0)
	to notify that Korea Limb SAR applied.
- Driver will read the WGDS table and pass the values to FW (as usual)
- Driver will pass to FW an indication that Korea Limb SAR is applied
	in case table revision is 1.

[PATCH 09/20] iwlwifi: mvm: Drop large non sta frames

[Luca Coelho]

From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>

In some buggy scenarios we could possible attempt to transmit frames larger
than maximum MSDU size. Since our devices don't know how to handle this,
it may result in asserts, hangs etc.
This can happen, for example, when we receive a large multicast frame
and try to transmit it back to the air in AP mode.
Since in a legal scenario this should never happen, drop such frames and
warn about it.

[PATCH 10/20] iwlwifi: pcie: increase the size of PCI dumps

[Luca Coelho]

From: Luca Coelho <luciano.coelho@intel.com>

Currently we dump only the first 64 bytes of the PCI config space,
which leaves out some important things, such as the base address
registers.

Increase it to 352 for the PCI device and to 524 for the rootport to
make sure we include everything we need.

[PATCH 11/20] iwlwifi: dbg: fix debug monitor stop and restart delays

[Luca Coelho]

From: Shahar S Matityahu <shahar.s.matityahu@intel.com>

The driver should delay only in recording stop flow between writing to
DBGC_IN_SAMPLE register and DBGC_OUT_CTRL register. Any other delay is
not needed.

Change the following:
1. Remove any unnecessary delays in the flow
2. Increase the delay in the stop recording flow since 100 micro is
   not enough
3. Use usleep_range instead of delay since the driver is allowed to
   sleep in this flow.

[PATCH 13/20] iwlwifi: dbg_ini: remove redundant checking of ini mode

[Luca Coelho]

From: Shahar S Matityahu <shahar.s.matityahu@intel.com>

There are several flows where the driver checks if it runs in ini mode.
Some of these flows are no longer used in ini mode or there is another
condition that check the ini mode in the same flow. Either way, those
conditions are redundant. Remove the redundant conditions.

[PATCH 19/20] iwlwifi: dbg: debug recording stop and restart command remove

[Luca Coelho]

From: Shahar S Matityahu <shahar.s.matityahu@intel.com>

The 0xF6 command used to start and stop the recording from 22560 devices
was removed. This is causing an assert when the driver tries to alter
the recording state.
Remove the use of the command.

[PATCH 20/20] iwlwifi: mvm: remove MAC_FILTER_IN_11AX for AP mode

[Luca Coelho]

From: Luca Coelho <luciano.coelho@intel.com>

The FW API was clarified saying that this flag should only be set in
BSS client mode.  Remove it from the MAC_CTXT command we send in AP
and GO modes.
