We need to use a different firmware for C0 versions of killer Qu NICs.
Add structures for them and handle them in the if block that detects
C0 revisions.
Additionally, instead of having an inclusive check for QnJ devices,
make the selection exclusive, so that switching to QnJ is the
exception, not the default. This prevents us from having to add all
the non-QnJ cards to an exclusion list. To do so, only go into the
QnJ block if the device has an RF ID type HR and HW revision QnJ.

The MAC context configuration always allowed multicast data frames
to pass to the driver for all MAC context types, and in the
case of station MAC context both when associated and when not
associated.
One of the outcomes of this configuration is having the FW forward
encrypted multicast frames to the driver with Rx status indicating
that the frame was not decrypted (as expected, since no keys were
configured yet) which in turn results with unnecessary error
messages.
Change this behavior to allow multicast data frames only when they
are actually expected, e.g., station MAC context is associated etc.

An earlier patch made sure that the queues are not lagging

should not be called with a head_sn too far behind NSSN.
Don't take the risk to change completely the entry
condition to iwl_mvm_release_frames, but don't update
the head_sn is the NSSN is more than 2048 packets ahead
of us. Since this just cannot be right. This means that

In order to support MSI-X efficiently, we want to avoid
communication across Rx queues. Each Rx queue should have
all the data it needs to process a packet.
The reordering buffer is a challenge in the MSI-X world
since we can have a single BA session whose packets are
directed to different queues. This is why each queue has
its own reordering buffer. The hardware is able to hint
the driver whether we have a hole or not, which allows
the driver to know whether it can release a packet or not.
This indication is called NSSN. Roughly, if the packet's
SN is lower than the NSSN, we can release the packet to
the stack. The NSSN is the SN of the newest packet received
without any holes + 1.
This is working as long as we don't have packets that we
release because of a timeout. When that happens, we could
have taken the decision to release a packet after we have
been waiting for its predecessor for too long. If this
predecessor comes later, we have to drop it because we
can't release packets out of order. In that case, the
hardware will give us an indication that we can we release
the packet (SN < NSSN), but the packet still needs to be
dropped.
This is why we sometimes need to ignore the NSSN and we
track the head_sn in software.
Here is a specific example of this:
1) Rx queue 1 got packets: 480, 482, 483
2) We release 480 to to the stack and wait for 481
3) NSSN is now 481
4) The timeout expires
5) We release 482 and 483, NSSN is still 480
6) 481 arrives its NSSN is 484.
We need to drop 481 even if 481 < 484. This is why we'll
update the head_sn to 484 at step 2. The flow now is:
1) Rx queue 1 got packets: 480, 482, 483
2) We release 480 to to the stack and wait for 481
3) NSSN is now 481 / head_sn is 481
4) The timeout expires
5) We release 482 and 483, NSSN is still 480 but head_sn is 484.
6) 481 arrives its NSSN is 484, but head_sn is 484 and we drop it.
This code introduces another problem in case all the traffic
goes well (no hole, no timeout):
Rx queue 1: 0 -> 483 (head_sn = 484)
Rx queue 2: 501 -> 4095 (head_sn = 0)
Rx queue 2: 0 -> 480 (head_sn = 481)
Rx queue 1: 481 but head_sn = 484 and we drop it.
At this point, the SN of queue 1 is far behind: more than
4040 packets behind. Queue 1 will consider 481 "old"
because 481 is in [501-64:501] whereas it is a very new
packet.
In order to fix that, send an Rx notification from time to
time (twice across the full set of 4096 packets) to make
sure no Rx queue is lagging too far behind.
What will happen then is:
Rx queue 1: 0 -> 483 (head_sn = 484)
Rx queue 2: 501 -> 2047 (head_sn = 2048)
Rx queue 1: Sync nofication (head_sn = 2048)
Rx queue 2: 2048 -> 4095 (head_sn = 0)
Rx queue 1: Sync notification (head_sn = 0)
Rx queue 2: 1 -> 481 (head_sn = 482)
Rx queue 1: 481 and head_sn = 0.
In queue 1's data, head_sn is now 0, the packet coming in
is 481, it'll understand that the new packet is new and it
won't be dropped.

On older NICs, we occasionally see issues with A-MSDU support,
where the commands in the FIFO get confused and then we see an

We've tried to isolate this issue and understand where it comes
from, but haven't found any errors in building the A-MSDU in
software.
At least for now, disable A-MSDU support on older hardware so
that users can use it again without fearing the assert.

When calling debugfs functions, there is no need to ever check the
return value. This driver was saving the debugfs file away to be
removed at a later time. However, the 80211 core would delete the whole
directory that the debugfs files are created in, after it asks the
driver to do the deletion, so just rely on the 80211 core to do all of
the cleanup for us, making us not need to keep a pointer to the dentries
around at all.
This cleans up the structure of the driver data a bit and makes the code
a tiny bit smaller.

Merge tag 'docs-5.3' of git://git.lwn.net/linux
Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc"

iwl_mvm_send_cmd returns 0 when the command won't be sent
because RF-Kill is asserted. Do the same when we call
iwl_get_shared_mem_conf since it is not sent through
iwl_mvm_send_cmd but directly calls the transport layer.

Sometimes the register status can include interrupts that
were masked. We can, for example, get the RF-Kill bit set
in the interrupt status register although this interrupt
was masked. Then if we get the ALIVE interrupt (for example)
that was not masked, we need to *not* service the RF-Kill
interrupt.
Fix this in the MSI-X interrupt handler.

Newest devices have a new firmware load mechanism. This
mechanism is called the context info. It means that the
driver doesn't need to load the sections of the firmware.
The driver rather prepares a place in DRAM, with pointers
to the relevant sections of the firmware, and the firmware
loads itself.
At the end of the process, the firmware sends the ALIVE
interrupt. This is different from the previous scheme in
which the driver expected the FH_TX interrupt after each
section being transferred over the DMA.
In order to support this new flow, we enabled all the
interrupts. This broke the assumption that we have in the
code that the RF-Kill interrupt can't interrupt the firmware
load flow.
Change the context info flow to enable only the ALIVE
interrupt, and re-enable all the other interrupts only
after the firmware is alive. Then, we won't see the RF-Kill
interrupt until then. Getting the RF-Kill interrupt while
loading the firmware made us kill the firmware while it is
loading and we ended up dumping garbage instead of the firmware
state.
Re-enable the ALIVE | RX interrupts from the ISR when we
get the ALIVE interrupt to be able to get the RX interrupt
that comes immediately afterwards for the ALIVE
notification. This is needed for non MSI-X only.

We added code to restock the buffer upon ALIVE interrupt
when MSI-X is disabled. This was added as part of the context
info code. This code was added only if the ISR debug level
is set which is very unlikely to be related.
Move this code to run even when the ISR debug level is not
set.
Note that gen2 devices work with MSI-X in most cases so that
this path is seldom used.

In AP (and IBSS) mode, we can only set GTKs to firmware after we have
sent down the multicast station, but this we can only do after we've
enabled beaconing, etc.
However, during rfkill exit, hostapd will configure the keys before
starting the AP, and cfg80211/mac80211 accept it happily.
On earlier devices, this didn't bother us as GTK TX wasn't really
handled in firmware, we just put the key material into the TX cmd
and thus it only mattered when we actually transmitted a frame.
On newer devices, however, the firmware needs to track all of this
and that doesn't work if we add the key before the (multicast) sta
it belongs to.
To fix this, keep a list of keys to add during AP enable, and call
the function there.

Change the following:

not enough
3. Use usleep_range instead of delay since the driver is allowed to

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.

When calling debugfs functions, there is no need to ever check the
return value. This driver was saving the debugfs file away to be
removed at a later time. However, the 80211 core would delete the whole
directory that the debugfs files are created in, after it asks the
driver to do the deletion, so just rely on the 80211 core to do all of
the cleanup for us, making us not need to keep a pointer to the dentries

This cleans up the structure of the driver data a bit and makes the code

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

When we have a single image (same firmware image for INIT and
OPERATIONAL), we couldn't load the driver and register to the
stack if we had hardware RF-Kill asserted.
Fix this. This required a few changes:
1) Run the firmware as part of the INIT phase even if its
ucode_type is not IWL_UCODE_INIT.
2) Send the commands that are sent to the unified image in
INIT flow even in RF-Kill.
3) Don't ask the transport to stop the hardware upon RF-Kill
interrupt if the RF-Kill is asserted.
4) Allow the RF-Kill interrupt to take us out of L1A so that
the RF-Kill interrupt will be received by the host (to
enable the radio).

In the dump info, the driver sets device_family to
IWL_FW_ERROR_DUMP_FAMILY_7 in case IWL_FW_ERROR_DUMP_FAMILY_7 is used or
IWL_FW_ERROR_DUMP_FAMILY_8 otherwise. This information is misleading and
incorrect since the driver sets the device family to 8 to any device that
is from family 8 and later, e.g. device family 9 is represented as 8 in
the dump.
Also, the device family enum is known only to the driver and
does not give any information to the FW developer
Change the device family to HW type to give propper data about the nic
in use.

When the interface that is requesting an FTM measurement is connected
to a BSS, it is possible that the FTM request was originated by an
RRM request from the AP. In this case the station needs to report
the measurement start time in terms of the TSF of the AP.
Since there is no indication in the FTM request itself if the TSF
is needed, always report the TSF if the station is associated.

We don't check for the validity of the lengths in the packet received
from the firmware. If the MPDU length received in the rx descriptor
is too short to contain the header length and the crypt length
together, we may end up trying to copy a negative number of bytes
(headlen - hdrlen < 0) which will underflow and cause us to try to
copy a huge amount of data. This causes oopses such as this one:

We currently have two levels of strict validation:
1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size
The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().
Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.
We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.
Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.
Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.
In effect then, this adds fully strict validation for any new command.
