[PATCH 00/18] iwlwifi: updates intended for v4.21 2018-12-14

[Luca Coelho]

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

Hi,

Here's the fourth set of patches intended for v4.21.  It's the usual
development, with support for a new FW version, some small new
features, cleanups and bugfixes.

The changes are:

* Support for FW version 43 for 9000 and 22000 series;
* A couple of janitorial fixes from the community;
* More fixes in the 802.11ax code;
* Other cleanups and small fixes;

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 01/18] iwlwifi: pcie: use iwl_tx_cmd_gen2 and not iwl_tx_cmd

[Luca Coelho]

From: Sara Sharon <sara.sharon@intel.com>

When building AMSDU for gen2, code uses iwl_tx_cmd. The only
updated field is len, which is in the same location, so it
is not a bug. However, it is a bit confusing and error prone,
so change it.

[PATCH 02/18] iwlwifi: mvm: remove dead code

[Luca Coelho]

From: Sara Sharon <sara.sharon@intel.com>

In iwl_mvm_tx_skb_non_sta(), in case of managed interface,
the AP station was supposed to be used for multicast frames
instead of the auxiliary station to avoid frames possibly
sent to an absent P2P GO. However, when moving to DQA mode,
this was broken as no valid queue was assigned. This is fixed
by a recent patch that directs all non-offchannel traffic to
ap station earlier in the TX path. However, the broken, and
now dead code, remained. Remove it.

[PATCH 03/18] iwlwifi: mvm: remove pointless NULL assignment

[Luca Coelho]

From: Sara Sharon <sara.sharon@intel.com>

Assigning mvmsta to be NULL when we are about to exit the
function is pointless. Remove it. Move the variable declaration
to the scope it is used.

[PATCH 05/18] iwlwifi: mvm: fix setting HE ppe FW config

[Luca Coelho]

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

The FW expects to get the ppe value for each NSS-BW pair in the same
format as in the he phy capabilities IE, which means that a value of 0
implies ppe should be used for BPSK (mcs 0). If there are no PPE
thresholds in the IE, or if for some NSS-RU pair there's no threshold
set for it (this could happen because it's a variable-sized field), it
means no PPE should not be used for that pair, so the value sent to FW
should be 7 which corresponds to "none".

It's not the iwlwifi module that depends on mac80211, but iwlmvm and
iwldvm.  To reflect this better, make MVM and DVM Kconfig options
depend on MAC80211 instead.

[PATCH 09/18] iwlwifi: mvm: take station lock later in the code

There is no need to lock mvm station for transport reclaim.
Move the locking down, after the reclaim.

[PATCH 10/18] iwlwifi: pcie: lock txq a bit later in reclaim code

[Luca Coelho]

From: Sara Sharon <sara.sharon@intel.com>

In reclaim code, we don't need to take the queue lock for
waking the queue. The code section is executed only when
the tx path is stopped, and since the reclaim path is not
executed in parallel to itself, no one can update the queue
pointers, and accessing them is safe without a lock.

[PATCH 11/18] iwlwifi: mvm: clean up SSN incrementation

[Luca Coelho]

From: Sara Sharon <sara.sharon@intel.com>

Sometimes, due to SCD bug, we need to start the queue with an
higher SSN. The queue allocation function currently increments
the SSN in the packet itself, but it is pointless, since this
value is overridden later by iwl_mvm_tx_mpdu with the value
from mvmsta->tid_data[tid].seq_number. Updating tid data is
sufficient.

[PATCH 16/18] iwlwifi: mvm: d3: use struct_size() in kzalloc()

[Luca Coelho]

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

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
	int stuff;
        void *entry[];
};

instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

This issue was detected with the help of Coccinelle.

The subject is broken, stray "[BUGFIX". I think you are offline already
so I can fix it myself but I need to rebase the patches. I assume that's
ok unless someone from Intel objects :)

Ouch, sorry.  Internal tag leaked out.  That's what happens when you try
to finish too many things in a hurry before vacations. :(
