I had to remove the long list of maintainers got by
getpatch.pl, as it was too long. I opted to keep only the
mailing lists.

Those files are actually at ReST format. Ok, currently, they
don't belong to any place yet at the organized book series,
but we don't want patches to break them as ReST files. So,
rename them and add a :orphan: in order to shut up warning
messages like those:
...
Documentation/svga.rst: WARNING: document isn't included in any toctree
Documentation/switchtec.rst: WARNING: document isn't included in any toctree
...
Later patches will move them to a better place and remove the
:orphan: markup.

I had to remove the long list of maintainers got by
getpatch.pl, as it was too long. I opted to keep only the
mailing lists.

The only improvement would be to document this more clearly in the "WPA/WPA2 EAPOL handshake offload" DOC section in nl80211.h.
so nl80211 is an API. And an application can use that API wrongly (be that intentionally or unintentionally), the kernel can not just go WARN_ON and print a backtrace. That is your bug. So please handle wrong user input properly.
Frankly, I don’t get why nl80211 itself is not validating the input and this is left to the driver. I think we need a nl80211 fuzzer that really exercises this API with random values and parameters to provide invalid input.

* [PATCH V2 0/2] mac80211: add ADDBA_EXT responder support
From: John Crispin @ 2019-06-19 5:30 UTC (permalink / raw)
To: Johannes Berg; +Cc: linux-wireless, John Crispin
HE allows peers to negotiate the aggregation fragmentation level to be used
during transmission. The level can be 1-3. The Ext element is added behind
the ADDBA request inside the action frame. The responder will then reply
with the same level or a lower one if the requested one is not supported.
This patch only handles the responder part.

* [PATCH V7 0/2] mac80211: add 802.11 encapsulation offloading
From: John Crispin @ 2019-06-19 8:04 UTC (permalink / raw)
To: Johannes Berg, Kalle Valo; +Cc: linux-wireless, ath10k, John Crispin
This series picks up prior work from QCA. The patch is currently shipped
inside QSDK as part of the wlan-open package.
The series tries to address all feedback from the V2
-> https://patchwork.kernel.org/patch/9602585/
Changes in V3
* rebase on latest kernel
* various code style clean ups
* give some of the variables and functions more obvious names
* move the code that disables support for non-linear frames to the core
* disable monitor and tkip support
Changes in V4
* disable encap when TKIP is used instead of refusing TKIP
* use a flag inside tx_info instead of an extra element
* move 4addr detection into ieee80211_set_hw_80211_encap()
* ieee80211_tx_dequeue() was dropping out to early
Changes in V5
* implement comments from Johannes
Changes in V6
* the conditional masking out monitor support was inverse
Changes in V7
* dont mask out monitor support when encap is available. Instead turn encap
of if a monitor device is brought up or already present

* [PATCH V7 2/2] ath10k: add tx hw 802.11 encapusaltion offloading suppor
From: John Crispin @ 2019-06-19 8:04 UTC (permalink / raw)
To: Johannes Berg, Kalle Valo
Cc: linux-wireless, ath10k, Vasanthakumar Thiagarajan, John Crispin
In-Reply-To: <20190619080457.17135-1-john@phrozen.org>
From: Vasanthakumar Thiagarajan <vthiagar@qti.qualcomm.com>
This patch adds support for ethernet rxtx mode to the driver. The feature
is enabled via a new module parameter. If enabled to driver will enable
the feature on a per vif basis if all other requirements were met.
Testing on a IPQ4019 based hardware shows a increase in TCP throughput
of ~20% when the feature is enabled.

* [PATCH V7 1/2] mac80211: add hw 80211 encapsulation offloading support
From: John Crispin @ 2019-06-19 8:04 UTC (permalink / raw)
To: Johannes Berg, Kalle Valo
Cc: linux-wireless, ath10k, Vasanthakumar Thiagarajan, John Crispin
In-Reply-To: <20190619080457.17135-1-john@phrozen.org>
From: Vasanthakumar Thiagarajan <vthiagar@qti.qualcomm.com>
This patch adds a new transmit path for hardware that supports 802.11
encapsulation offloading. In those cases 802.3a frames get passed
directly to the driver allowing to hardware to handle the encapsulation.
Certain features wont work and the patch masks these out.
* monitor interfaces are not supported if any of the vif is in encap mode.
* amsdu/non-linear frames wont work in encap offloading mode.
* TKIP countermeasures cannot be triggered and hence those keys are not
accepted.
The patch defines a secondary netdev_ops struct that the device is assigned
to the device if 802.11 encap support is available and enabled. The driver
needs to enable the support on a per vif basis if it finds that all
pre-reqs are meet.

Forgive my ignorance about rfkill. At least in this Tegra case, it
sounds like rfkill basically controls a power switch for the entire
device, i.e., it doesn't merely turn off the radio portion of the
device; it puts the entire PCI device in D3cold.
Is rfkill integrated with the power management subsystem? E.g., when
lspci or X tries to read config space via pci_read_config(), does the
pci_config_pm_runtime_get() in that path wake up the device?
IMO, if the struct pci_dev exists, we should be able to rely on the
device actually being accessible (possibly after bringing it back to
D0). If rfkill only turns off the radio, leaving the PCI interface
active, that would be fine -- in that case generic PCI things like
lspci would work normally and it would be up to the driver to manage
network-related things.
But if rfkill turns off PCI interface and the power management
subsystem can't wake it up, I think we should unbind the driver and
remove the pci_dev, so it wouldn't appear in lspci at all.

Sort of. The actual (hardware) implementation seems a bit more
complicated than a "power switch", but yes, that's the effect of it.

No, that's the problem at hand AFAICT.

Right. That's being suggested here, but since the platform has no actual
hardware hotplug, that needs to be implemented in software.
The question at hand is *how* to actually achieve that.
I'm kind of arguing that it's not rfkill that achieves it, but the
underlying GPIO that toggles the device, since that GPIO could also be
bound to something other than an rfkill-gpio instance.

Gah, this addr gets fed into io_remap_pfn_range/remap_pfn_range too..
Potnuri, you should fix this..
You probably need to use dma_mmap_from_dev_coherent() in the mmap ?

Changing hexdump's last argument from bool to int is odd.
Perhaps a new function should be added instead of changing
the existing hexdump.

* [PATCH 2/6] iwlwifi: pcie: fix ALIVE interrupt handling for gen2 devices w/o MSI-X
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Emmanuel Grumbach, Luca Coelho
In-Reply-To: <20190619174159.13927-1-luca@coelho.fi>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
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.

* [PATCH 1/6] iwlwifi: mvm: delay GTK setting in FW in AP mode
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Johannes Berg, Luca Coelho
In-Reply-To: <20190619174159.13927-1-luca@coelho.fi>
From: Johannes Berg <johannes.berg@intel.com>
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.

* [PATCH 3/6] iwlwifi: fix RF-Kill interrupt while FW load for gen2 devices
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Emmanuel Grumbach, Luca Coelho
In-Reply-To: <20190619174159.13927-1-luca@coelho.fi>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
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.

* [PATCH 4/6] iwlwifi: pcie: don't service an interrupt that was masked
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Emmanuel Grumbach, Luca Coelho
In-Reply-To: <20190619174159.13927-1-luca@coelho.fi>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
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.

* [PATCH 5/6] iwlwifi: don't WARN when calling iwl_get_shared_mem_conf with RF-Kill
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Emmanuel Grumbach, Luca Coelho
In-Reply-To: <20190619174159.13927-1-luca@coelho.fi>
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
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.

* [PATCH 0/6] iwlwifi: fixes intended for 5.2 2019-06-19
From: Luca Coelho @ 2019-06-19 17:41 UTC (permalink / raw)
To: kvalo; +Cc: linux-wireless, Luca Coelho
From: Luca Coelho <luciano.coelho@intel.com>
Hi,
This is the third patchset with fixes for v5.2.
The changes are:
* A bunch of RF-kill fixes by Emmanuel;
* A fix for AP mode, also related to RF-kill, by Johannes.
As usual, I'm pushing this to a pending branch, for kbuild bot. And
as we agreed, I'll delegate these patches to you in patchwork for you
to apply them directly.
Please review.
Cheers,
Luca.
