d1836e2308 nl80211: Introduce the interface to update new DH IE
This command/event interface can be used by SME based host drivers that
rely on user space (hostapd/wpa_supplicant) for DH IE
processing/generation. This interface facilitates the OWE connection
with host drivers by offloading DH IE processing to the user space
(hostapd/wpa_supplicant).

b6f8b5a964 nl80211: Update freq only when CSA completes
In the case of the ap_csa_disable test, I frequently see
failures due to the kernel *not* having switched, but the
CSA-STARTED event having been processed, and thus the
frequency having been updated already.

This is wrong at least for AP mode, the frequency we store
for this case internally in nl80211 should only be updated
when the channel switch completes, otherwise we end up in
a situation where the switch is aborted and the kernel is
thus on the old channel, but the internal information has
been updated and every subsequent mgmt-frame TX fails due
to being tagged with the wrong channel.

c5fff8bbd2 nl80211: Update assoc_freq and bss->freq based on real association info
Move event.assoc_info.freq selection to be after the
nl80211_get_assoc_ssid() call so that the current cfg80211 information
on the operating channel can be used should anything unexpected have
happened between the association request and completion of association.
Furthermore, update bss->freq based on assoc_freq to make that
information a bit more useful for station mode. It was already updated
after channel switches during association, but not at the beginning of
association.

dd1a8cef4c Remove unnecessary copying of SSID and BSSID for external_auth

ed0a4ddc22 nl80211: Update drv->ssid on connect/associate event based on BSS data
On a connect nl80211 event, wpa_supplicant uses
wpa_driver_nl80211_get_ssid() to fetch the current associated SSID to
compare to existing configurations. However,
wpa_driver_nl80211_get_ssid() uses drv->ssid, which is a cached value.
It is set when we explicitly initial a connect request using
wpa_supplicant. If the association was initiated outside of
wpa_supplicant, we need another way to populate drv->ssid. This commit
sets drv->ssid based on cfg80211 BSS information on connect/associate
nl80211 events.

9f346fadc8 nl80211: Fix scan_state update in no pending scan state
Commit adcd7c4b0b ('nl80211: Support
vendor scan together with normal scan') made the drv->scan_state updates
for NL80211_CMD_NEW_SCAN_RESULTS and NL80211_CMD_SCAN_ABORTED
conditional on drv->last_scan_cmd being NL80211_CMD_TRIGGER_SCAN. This
missed the part about the possibility of last_scan_cmd == 0 and an
externally started cfg80211 scan is ending. This could leave
drv->scan_state into SCAN_STARTED state even after the scan was
completed. Consequently, hwsim test cases could get stuck in reset()
handler waiting for scan to terminate.

Fix this by updating drv->scan_state also in drv->last_scan_cmd == 0
case.

4653ceb750 nl80211: Report disassociated STA / lost peer for the correct BSS
We shouldn't use drv->ctx as it always points to the first BSS. When
using FullMAC driver with multi-BSS support it resulted in incorrect
treating nl80211 events. I noticed with with brcmfmac and BCM43602.

Before my change I was getting "disassociated" on a wrong interface:
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
wlan0: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated

With this patch it works as expected:
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated
wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN)
wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated

AP SME & MLME is done it hostapd not the firmware.

757785dab2 nl80211: Clear ignore_next_local_deauth flag
The de-authentication flow in wpa_driver_nl80211_deauthenticate() can
result in a locally generated de-authentication event. To avoid getting
this extra event ignore_next_local_deauth flag is set, and should be
cleared when the next local deauth event is received. However, it is not
cleared when the event shows up after the wpa_supplicant has started a
connection with a new AP, and as a result it might ignore future
deauth event from the driver.

Fix this by clearing the flag if the event is locally generated.
