Oldřich Jedlička 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.

Felix Fietkau ddd977fcc5 mac80211: fix regression in SSN handling of addba tx
Some drivers that do their own sequence number allocation (e.g. ath9k, mwlwifi) rely
on being able to modify params->ssn on starting tx ampdu sessions.
This was broken by a change that modified it to use sta->tid_seq[tid] instead.

Bastian Bittorf ea5fce3f46 mac80211: fix IBSS/adhoc mode for brcmfmac
On systems using brmcfmac (e.g. Raspberry Pi Zero W) without this fix,
the final setup-call:
iw dev wlan0 ibss join ...

fails with returncode 161 and message:
"command failed: Not supported (-95)"

So this patch calls an explicit:
iw dev wlan0 set type ibss
just prior to the 'ibss join' command.

I have tested several ath9k and mt76xx devices
with different revisions: this patch does not harm.

please also apply to stable branch.

Hauke Mehrtens c90e10b62e mac80211: Fix deadlock when configuring wifi
The nl80211_set_wiphy() function was changed between kernel 5.11 and
5.12 to take the rdev->wiphy lock which should be freed at the end
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
configuration options:
CONFIG_KERNEL_DETECT_HUNG_TASK=y
CONFIG_KERNEL_PROVE_LOCKING=y

Christian Lamparter d91318662d ath9k: nvmem for ath9k caldata
With "getting WIFI MAC from NVMEM" working on ath79 on 5.10,
the next logical step I think is to utilize nvmem subsystem
to also get the calibration data from there.

This will tremendously speed up the wifi bring-up, since
we no longer need the userspace helper for the simple
devices that can just load them from there.

included with this patch is a package/mac80211/refresh.

Tested on: WNDR3700v2, TP-Link Archer C7v2

Christian Lamparter 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.

Bob Cantor 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.

Bob Cantor 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.
