commit 5122565188bae59d507d90a9a9fd2fd6107f4439 upstream.
Since cfg80211 doesn't implement commit, we never really cared about
that code there (and it's configured out w/o CONFIG_WIRELESS_EXT).
After all, since it has no commit, it shouldn't return -EIWCOMMIT to
indicate commit is needed.
However, EIWCOMMIT is actually an alias for EINPROGRESS, which _can_
happen if e.g. we try to change the frequency but we're already in
the process of connecting to some network, and drivers could return
that value (or even cfg80211 itself might).
This then causes us to crash because dev->wireless_handlers is NULL
but we try to check dev->wireless_handlers->standard[0].
Fix this by also checking dev->wireless_handlers. Also simplify the
code a little bit.

old mode where this doesn't happen.
However, in this case we were not resetting our state correctly

broken such older userspace.
This was broken pretty much immediately afterwards because it
only worked in the original commit where non-split dumps didn't

Currently when an AP and STA interfaces are active in the same or different
radios, regulatory settings are restored whenever the STA disconnects. This
restores all channel information including dfs states in all radios.
For example, if an AP interface is active in one radio and STA in another,
when radar is detected on the AP interface, the dfs state of the channel
will be changed to UNAVAILABLE. But when the STA interface disconnects,
this issues a regulatory disconnect hint which restores all regulatory
settings in all the radios attached and thereby losing the stored dfs
state on the other radio where the channel was marked as unavailable
earlier. Hence prevent such regulatory restore whenever another active
beaconing interface is present in the same or other radios.

After Disconnect, similar to above, country code should not be reset to

To address this, avoid regulatory restore from regulatory_hint_disconnect()

Commit 33d915d9e8ce ("{nl,mac}80211: allow 4addr AP operation on
crypto controlled devices") has introduced a change which allows
4addr operation on crypto controlled devices (ex: ath10k). This
change has inadvertently impacted the interface combinations logic
on such devices.
General rule is that software interfaces like AP/VLAN should not be
listed under supported interface combinations and should not be
considered during validation of these combinations; because of the
aforementioned change, AP/VLAN interfaces(if present) will be checked
against interfaces supported by the device and blocks valid interface
combinations.
Consider a case where an AP and AP/VLAN are up and running; when a
second AP device is brought up on the same physical device, this AP
will be checked against the AP/VLAN interface (which will not be
part of supported interface combinations of the device) and blocks
second AP to come up.
Add a new API cfg80211_iftype_allowed() to fix the problem, this
API works for all devices with/without SW crypto control.

commit 0d31d4dbf38412f5b8b11b4511d07b840eebe8cb upstream.
This reverts commit 96cce12ff6 ("cfg80211: fix processing world
regdomain when non modular").
Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.
This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
- checks if previous was set by CORE -> yes
- checks if regulator domain changed -> yes, from '00' to e.g. 'US'
-> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
is not processed yet, so it tries to process it again.
__reg_process_hint driver() will run again, and:
- checks if the last request's initiator was the core -> no, it was
the driver (1st WiFi module)
- checks, if the previous initiator was the driver -> yes
- checks if the regulator domain changed -> yes, it was '00' (set by
core, and crda call did not return yet), and should be changed to 'US'
------> __reg_process_hint_driver calls an intersect
Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.

commit 33d915d9e8ce811d8958915ccd18d71a66c7c495 upstream.
As per the current design, in the case of sw crypto controlled devices,
it is the device which advertises the support for AP/VLAN iftype based
on it's ability to tranmsit packets encrypted in software
(In VLAN functionality, group traffic generated for a specific
VLAN group is always encrypted in software). Commit db3bdcb9c3
("mac80211: allow AP_VLAN operation on crypto controlled devices")
has introduced this change.
Since 4addr AP operation also uses AP/VLAN iftype, this conditional
way of advertising AP/VLAN support has broken 4addr AP mode operation on
crypto controlled devices which do not support VLAN functionality.
In the case of ath10k driver, not all firmwares have support for VLAN
functionality but all can support 4addr AP operation. Because AP/VLAN
support is not advertised for these devices, 4addr AP operations are
also blocked.
Fix this by allowing 4addr operation on devices which do not support
AP/VLAN iftype but can support 4addr AP operation (decision is based on
the wiphy flag WIPHY_FLAG_4ADDR_AP).

[ Upstream commit 5dc8cdce1d722c733f8c7af14c5fb595cfedbfa8 ]
FullMAC STAs have no way to update bss channel after CSA channel switch
completion. As a result, user-space tools may provide inconsistent
channel info. For instance, consider the following two commands:
$ sudo iw dev wlan0 link
$ sudo iw dev wlan0 info
The latter command gets channel info from the hardware, so most probably
its output will be correct. However the former command gets channel info
from scan cache, so its output will contain outdated channel info.
In fact, current bss channel info will not be updated until the
next [re-]connect.
Note that mac80211 STAs have a workaround for this, but it requires
access to internal cfg80211 data, see ieee80211_chswitch_work:
/* XXX: shouldn't really modify cfg80211-owned data! */
ifmgd->associated->channel = sdata->csa_chandef.chan;

This commit adds NL80211_FLAG_CLEAR_SKB flag to other NL commands
that carry key data to ensure they do not stick around on heap

Also introduced this flag for NL80211_CMD_VENDOR as there are sub
commands which configure the keys.
