commit a9149d243f upstream.
The logic for checking required NVM sections was recently fixed in
commit b3f20e0982 ("iwlwifi: mvm: fix NVM check for 3168
devices"). However, with that fixed the else is now taken for 3168
devices and within the else clause there is a mandatory check for the
PHY_SKU section. This causes the parsing to fail for 3168 devices.
The PHY_SKU section is really only mandatory for the IWL_NVM_EXT
layout (the phy_sku parameter of iwl_parse_nvm_data is only used when
the NVM type is IWL_NVM_EXT). So this changes the PHY_SKU section
check so that it's only mandatory for IWL_NVM_EXT.

[ Upstream commit 12d47f0ea5 ]
Fix a kernel panic by checking that the sta is not NULL.
This could happen during a reconfig flow, as mac80211 moves the sta
between all the states without really checking if the previous state was
successfully set. So, if for some reason we failed to add back the
station, subsequent calls to sta_state() callback will be done when the
station is NULL. This would result in a following panic:

calls cfg80211_pmsr_complete() for that request.
However, cfg80211 frees the requested data immediately after sending

Commit 323ebb61e3 ("net: use listified RX for handling GRO_NORMAL
skbs") introduces batching of GRO_NORMAL packets in napi_frags_finish,
and commit 6570bc79c0 ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") adds the same to napi_skb_finish. However,
dev_gro_receive (that is called just before napi_{frags,skb}_finish) can
also pass skbs to the networking stack: e.g., when the GRO session is
flushed, napi_gro_complete is called, which passes pp directly to
netif_receive_skb_internal, skipping napi->rx_list. It means that the
packet stored in pp will be handled by the stack earlier than the
packets that arrived before, but are still waiting in napi->rx_list. It
leads to TCP reorderings that can be observed in the TCPOFOQueue counter
in netstat.
This commit fixes the reordering issue by making napi_gro_complete also
use napi->rx_list, so that all packets going through GRO will keep their
order. In order to keep napi_gro_flush working properly, gro_normal_list
calls are moved after the flush to clear napi->rx_list.
iwlwifi calls napi_gro_flush directly and does the same thing that is
done by gro_normal_list, so the same change is applied there:
napi_gro_flush is moved to be before the flush of napi->rx_list.
A few other drivers also use napi_gro_flush (brocade/bna/bnad.c,
cortina/gemini.c, hisilicon/hns3/hns3_enet.c). The first two also use
napi_complete_done afterwards, which performs the gro_normal_list flush,
so they are fine. The latter calls napi_gro_receive right after
napi_gro_flush, so it can end up with non-empty napi->rx_list anyway.

After more investigation on the hardware side, it appears that the
hardware bug regarding 2^32 boundary reaching/crossing also affects
other uses of the DMA engine, in particular the ones triggered by
the context-info (image loader) mechanism.
It also turns out that the bug only affects devices with gen2 TX
hardware engine, so we don't need to change context info for gen3.
The TX path workarounds are simpler to still keep for both though.
Add the workaround to that code as well; this is a lot simpler as
we have just a single way to allocate DMA memory there.
I made the algorithm recursive (with a small limit) since it's
actually (almost) impossible to hit this today - dma_alloc_coherent
is currently documented to always return 32-bit addressable memory
regardless of the DMA mask for it, and so we could only get REALLY
unlucky to get the very last page in that area.

If we have offloaded rate scaling, which is always true for those
devices supporting HE, then report the TX rate directly from the
data the firmware gives us, instead of only passing it to mac80211
on frame status only and for it to track it.
First of all, this makes us always report the last good rate that
the rate scaling algorithm picked, which is better than reporting
the last rate for any frame since management frames etc. are sent
with very low rates and could interfere.
Additionally, this allows us to properly report HE rates, though
in case there's a lot of trigger-based traffic, we don't get any
choice in the rates and don't report that properly right now.

As noted in the previous commit, due to the way we allocate the
dev_cmd headers with 324 byte size, and 4/8 byte alignment, the
part we use of them (bytes 20..40-68) could still cross a page
and thus 2^32 boundary.
Address this by using alignment to ensure that the allocation
cannot cross a page boundary, on hardware that's affected. To
make that not cause more memory consumption, reduce the size of
the allocations to the necessary size - we go from 324 bytes in
each allocation to 60/68 on gen2 depending on family, and ~120
or so on gen1 (so on gen1 it's a pure reduction in size, since
we don't need alignment there).
To avoid size and clearing issues, add a new structure that's
just the header, and use kmem_cache_zalloc().

There's a hardware bug in the flow handler (DMA engine), if the
address + len of some TB wraps around a 2^32 boundary, the carry
bit is then carried over into the next TB.
Work around this by copying the data to a new page when we find
this situation, and then copy it in a way that we cannot hit the
very end of the page.
To be able to free the new page again later we need to chain it
to the TSO page, use the last pointer there to make sure we can
never use the page fully for DMA, and thus cannot cause the same
overflow situation on this page.
This leaves a few potential places (where we didn't observe the
problem) unaddressed:
* The second TB could reach or cross the end of a page (and thus
2^32) due to the way we allocate the dev_cmd for the header
* For host commands, a similar thing could happen since they're
just kmalloc().
We'll address these in further commits.

Commit 6570bc79c0 ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") has applied batched GRO_NORMAL packets processing
to all napi_gro_receive() users, including mac80211-based drivers.
However, this change has led to a regression in iwlwifi driver [1][2] as
it is required for NAPI users to call napi_complete_done() or
napi_complete() and the end of every polling iteration, whilst iwlwifi
doesn't use NAPI scheduling at all and just calls napi_gro_flush().
In that particular case, packets which have not been already flushed
from napi->rx_list stall in it until at least next Rx cycle.
Fix this by adding a manual flushing of the list to iwlwifi driver right
before napi_gro_flush() call to mimic napi_complete() logics.
I prefer to open-code gro_normal_list() rather than exporting it for 2
reasons:
* to prevent from using it and napi_gro_flush() in any new drivers,
as it is the *really* bad way to use NAPI that should be avoided;
* to keep gro_normal_list() static and don't lose any CC optimizations.
I also don't add the "Fixes:" tag as the mentioned commit was only a
trigger that only exposed an improper usage of NAPI in this particular
driver.
