cc15bd10e7 net: adopt skb_network_header_len() more broadly
(skb_transport_header(skb) - skb_network_header(skb))
can be replaced by skb_network_header_len(skb)

Add a DEBUG_NET_WARN_ON_ONCE() in skb_network_header_len()
to catch cases were the transport_header was not set.

4a62d588a8 thermal: core: Eliminate writable trip points masks
All of the thermal_zone_device_register_with_trips() callers pass zero
writable trip points masks to it, so drop the mask argument from that
function and update all of its callers accordingly.

This also removes the artificial trip points per zone limit of 32,
related to using writable trip points masks.

No intentional functional impact.

96c5330bf7 wifi: iwlwifi: mvm: Set THERMAL_TRIP_FLAG_RW_TEMP directly
It is now possible to flag trip points with THERMAL_TRIP_FLAG_RW_TEMP
to allow their temperature to be set from user space via sysfs instead
of using a nonzero writable trips mask during thermal zone registration,
so make the iwlwifi code do that.

No intentional functional impact.

Note that this change is requisite for dropping the mask argument from
thermal_zone_device_register_with_trips() going forward.

740dfecc33 wifi: iwlwifi: handle per-phy statistics from fw
In the operational statistics notifications (both old and new
API) the driver receives the statistics per phy.
currently this statistics wasn't handled because they wasn't needed.

Now the channel_load_by_us parameter in these statistics will be used
for the link grading calculation (implemented in another patch),
so store its value in phy_ctxt.

The firmware (later) actually uses the values even for keys
that are invalid as far as the host is concerned, later in

are only 48 bits over the air. It does, however, compare the
full 64 bits later, obviously causing problems.

Remove the memset and use kzalloc instead to avoid any old
heap data leaking to the firmware. We already init all the
other fields in the struct anyway. This leaves the data set
to zero for any unused fields, so the firmware can look at
them safely even if they're not used right now.

2e0e766bd8 wifi: iwlwifi: mvm: fix erroneous queue index mask
When retrieving the queue index ("SCD SSN") from the TX response,
it's currently masked with 0xFFF. However, now that we have queues
longer than 4k, that became wrong, so make the mask depend on the
hardware family.

This fixes an issue where if we get a single frame reclaim while
in the top half of an 8k long queue, we'd reclaim-wrap the queue
twice (once on this and then again on the next non-single reclaim)
which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(),
but could have other negative side effects (such as unmapping a
frame that wasn't transmitted yet, and then taking an IOMMU fault)
as well.

0c1c91604f wifi: iwlwifi: mvm: avoid garbage iPN
After waking from D3, we set the iPN given by the firmware.
For some reason, CIPHER_SUITE_AES_CMAC was missed.
That caused copying garbage to the iPN - causing false replays.

(since 'seq' is on the stack, and the iPN from the firmware
was not copied into it, it contains garbage which later is
copied to the iPN key).

If during D3 there was both a GTK rekey and a

The reason is that when disconnecting we first need

With unlimited pseudo-D3, we can get stuck here in the read if
the firmware never wakes up. All of our testing infrastructure
however will anyway give up after at most a minute, so there's
no value in that.

Limit this to about a minute to avoid getting stuck with the
RTNL held forever, which basically makes the machine unusable
and then we can't even understand what caused the failure.

When waking from D3 (and a GTK rekey happened during
D3), the key itself is saved in iwl_wowlan_status_data::gtk

The indices (of the same key) might differ in both arrays.
Fix using the gtk array index in the gtk_seq array.
Rather, iterate and search for the correct key in the
gtk_seq array.
