a10e0d7d35 mac80211: sync nl80211.h with upstream
Sync nl80211.h with upstream in order to maintain parity with
nl80211_copy.h shipped with hostapd.

This is necessary, as currently the enum value for
NL80211_EXT_FEATURE_RADAR_BACKGROUND mismatches between hostapd and
mac80211. This breaks background radar capability detection in hostapd.

7191d64d5d mac80211: introduce BSS color collision detection
Add ieee80211_rx_check_bss_color_collision routine in order to introduce
BSS color collision detection in mac80211 if it is not supported in HW/FW
(e.g. for mt7915 chipset).
Add IEEE80211_HW_DETECTS_COLOR_COLLISION flag to let the driver notify
BSS color collision detection is supported in HW/FW. Set this for ath11k
which apparently didn't need this code.

3daf2d477e mac80211: ath10k: backport bus and device specific API 1 BDF selection
Some ath10k IPQ40xx devices like the MikroTik hAP ac2 and ac3 require the
BDF-s to be extracted from the device storage instead of shipping packaged
API 2 BDF-s.

This is required as MikroTik has started shipping boards that require BDF-s
to be updated, as otherwise their WLAN performance really suffers.
This is however impossible as the devices that require this are release under
the same revision and its not possible to differentiate them from devices
using the older BDF-s.

In OpenWrt we are extracting the calibration data during runtime and we are
able to extract the BDF-s in the same manner, however we cannot package the
BDF-s to API 2 format on the fly and can only use API 1 to provide BDF-s on
the fly.
This is an issue as the ath10k driver explicitly looks only for the board.bin
file and not for something like board-bus-device.bin like it does for pre-cal
data.
Due to this we have no way of providing correct BDF-s on the fly, so lets
extend the ath10k driver to first look for BDF-s in the board-bus-device.bin
format, for example: board-ahb-a800000.wifi.bin
If that fails, look for the default board file name as defined previously.

So, backport the upstream ath10k patch.

7dc52a78ae mac80211: fix QCA9561 PA bias
This patch fixes an invalid TX PA DC bias level on QCA9561, which
results in a very low output power and very low throughput as devices
are further away from the AP (compared to other 2.4GHz APs),
following a suggestion from nbd[1].

This patch has been submitted upstream[2].

This reverts commit f9ff282d17 as during
upstream patch review process nbd pointed out, that this patch needs
more work:

 "The patch looks wrong to me. I'm pretty sure that AR_CH0_TOP2 is the
  correct register, the definition has an explicit check for 9561 as well.
  I believe this patch works by accident because it avoids writing a wrong
  value to that register."

f9ff282d17 mac80211 adjust QCA9561 PA bias
ath9k is setting the TX PA DC bias level different on QCA9561 and QCA9565
although they have the same radio IP-core, which results in a very low
output power and very low throughput as devices are further away from
the AP (compared to other 2.4GHz APs.)

In real life testing, without this patch the 2.4GHz throughput on Yuncore
XD3200 is around 10Mbps sitting close to the AP, and close to theoretical
maximum with the patch applied.

694757a08f kernel: ath10k: provide a build variant for small RAM devices
Based on: 1ac627024d ("kernel: ath10k-ct: provide a build variant for
small RAM devices")

Like described in the ath10k-ct-smallbuffers version, oom-killer gets
triggered frequently by devices with small RAM.

That change is necessary for many community mesh networks which use
ath10k based devices with too little RAM. The -ct driver has been
proven unstable if used with 11s meshing and only wave2 chipsets are
supporting 11s. Freifunk Berlin is nowadays assembling its
firmware-based completely of vanilla OpenWRT with some package additions
which are made through the imagebuilder. Therefore we cannot take the
approach other freifunk communities have taken to maintain that patch
downstream [1]. Other communities consider these devices as broken and
that change would pretty much give those devices a second life [2].

8d6a534cc1 mac80211: fixed missing cfg80211 dependency on kmod-rfkill
When compiling with CONFIG_USE_RFKILL=y, the build fails and mentions that
dependency on kmod-rfkill is missing, which is correct [1]. Add this
dependency to the Makefile.

Depend on +USE_RFKILL and not PACKAGE_kmod-rfkill, because it forces
selection of kmod-rfkill package. Other combinations in DEPENDS like
USE_RFKILL:kmod-rfkill or (+)PACKAGE_kmod-rfkill:kmod-rfkill do not force
selection of kmod-rfkill package.

The kmod-rfkill package itself depends on USE_RFKILL, so with +USE_RFKILL
in kmod-cfg80211 package it is not possible to select wrong combination of
packages.

c90e10b62e mac80211: Fix deadlock when configuring wifi
The nl80211_set_wiphy() function was changed between kernel 5.11 and

again. The 500-mac80211_configure_antenna_gain.patch added some code
which just returned in some cases without unlocking. This resulted in a
deadlock with brcmfmac.
This patch fixes this by also jumping to the out label in case we want
to leave the function.
This fixes a hanging system when brcmfmac is in use. I do not know why
we do not see this with other driver.

The kernel returns very useful debug details when setting these OpenWrt

4c8dd973ef ath9k: OF: qca,disable-(2|5)ghz => ieee80211-freq-limit
OpenWrt maintains two special out-of-tree DT properties:
"qca,disable-5ghz" and "qca,disable-2ghz". These are implemented
in a mac80211 ath9k patch "550-ath9k-disable-bands-via-dt.patch".

With the things being what they are, now might be a good
point to switch the devices to the generic and upstream
"ieee80211-freq-limit" property. This property is much
broader and works differently. Instead of disabling the
drivers logic which would add the affected band and
channels. It now disables all channels which are not
within the specified frequency range.

d515f6b6cd mac80211: always call wireless_set_data (FS#3784)
When wifi is turned off, drv_mac80211_teardown sometimes fails (silently)
because the device to be torn down is not defined.

This situation arises if drv_mac80211_setup was called twice when
wifi was turned on.

This commit ensures that the device to be torn down is always defined
in drv_mac80211_teardown.

Steps to reproduce:

1) Use /sbin/wifi to turn on wifi.
   uci set wireless.@wifi-iface[0].disabled=0
   uci set wireless.@wifi-device[0].disabled=0
   uci commit
   wifi

2) Use /sbin/wifi to turn off wifi.
   uci set wireless.@wifi-device[0].disabled=1
   uci commit
   wifi

3) Observe that wifi is still up.

a29ab3b79a mac80211: fix no_reload logic (FS#3902)
If drv_mac80211_setup is called twice with the same wifi configuration,
then the second call returns early with error HOSTAPD_START_FAILED.
(wifi works nevertheless, despite the fact that setup is incomplete.  But
"ubus call network.wireless status" erroneously reports that radio0 is down.)

The relevant part of drv_mac80211_setup is,

if [ "$no_reload" != "0" ]; then
        add_ap=1
        ubus wait_for hostapd
        local hostapd_res="$(ubus call hostapd config_add "{\"iface\":\"$primary_ap\", \"config\":\"${hostapd_conf_file}\"}")"
        ret="$?"
        [ "$ret" != 0 -o -z "$hostapd_res" ] && {
                wireless_setup_failed HOSTAPD_START_FAILED
                return
        }
        wireless_add_process "$(jsonfilter -s "$hostapd_res" -l 1 -e @.pid)" "/usr/sbin/hostapd" 1 1
fi

This commit sets no_reload = 0 during the second call of drv_mac80211_setup.

It is perhaps worth providing a way to reproduce the situation
where drv_mac80211_setup is called twice.

When /sbin/wifi is used to turn on wifi,
   uci set wireless.@wifi-iface[0].disabled=0
   uci set wireless.@wifi-device[0].disabled=0
   uci commit
   wifi

/sbin/wifi makes the following ubus calls,
   ubus call network reload
   ubus call network.wireless down
   ubus call network.wireless up

The first and third ubus calls both call drv_mac80211_setup,
while the second ubus call triggers wireless_device_setup_cancel.
So the call sequence becomes,

   drv_mac80211_setup
   wireless_device_setup_cancel
   drv_mac80211_setup

In contrast, when LuCI is used to turn on wifi only a single call
is made to drv_mac80211_setup.

025bd93f36 mac80211: backport upstream fixes for FragAttacks
From the patch series description:

Several security issues in the 802.11 implementations were found by
Mathy Vanhoef (New York University Abu Dhabi), who has published all
the details at

	https://papers.mathyvanhoef.com/usenix2021.pdf

Specifically, the following CVEs were assigned:

 * CVE-2020-24586 - Fragmentation cache not cleared on reconnection
 * CVE-2020-24587 - Reassembling fragments encrypted under different
                    keys
 * CVE-2020-24588 - Accepting non-SPP A-MSDU frames, which leads to
                    payload being parsed as an L2 frame under an
                    A-MSDU bit toggling attack
 * CVE-2020-26139 - Forwarding EAPOL from unauthenticated sender
 * CVE-2020-26140 - Accepting plaintext data frames in protected
                    networks
 * CVE-2020-26141 - Not verifying TKIP MIC of fragmented frames
 * CVE-2020-26142 - Processing fragmented frames as full frames
 * CVE-2020-26143 - Accepting fragmented plaintext frames in
                    protected networks
 * CVE-2020-26144 - Always accepting unencrypted A-MSDU frames that
                    start with RFC1042 header with EAPOL ethertype
 * CVE-2020-26145 - Accepting plaintext broadcast fragments as full
                    frames
 * CVE-2020-26146 - Reassembling encrypted fragments with non-consecutive
                    packet numbers
 * CVE-2020-26147 - Reassembling mixed encrypted/plaintext fragments

In general, the scope of these attacks is that they may allow an
attacker to
 * inject L2 frames that they can more or less control (depending on the
   vulnerability and attack method) into an otherwise protected network;
 * exfiltrate (some) network data under certain conditions, this is
   specific to the fragmentation issues.

A subset of these issues is known to apply to the Linux IEEE 802.11
implementation (mac80211). Where it is affected, the attached patches
fix the issues, even if not all of them reference the exact CVE IDs.

In addition, driver and/or firmware updates may be necessary, as well
as potentially more fixes to mac80211, depending on how drivers are
using it.

Specifically, for Intel devices, firmware needs to be updated to the
most recently released versions (which was done without any reference
to the security issues) to address some of the vulnerabilities.

To have a single set of patches, I'm also including patches for the
ath10k and ath11k drivers here.

We currently don't have information about how other drivers are, if
at all, affected.
