81ae8820a6 nl80211: Rename send_action_cookie to send_frame_cookie
This is to match the NL80211_CMD_ACTION renaming to NL80211_CMD_FRAME
that happened long time ago. This command can be used with any IEEE
802.11 frame and it should not be implied to be limited to Action
frames.

41cac481a8 ACS: Use frequency params in ACS (offload) completed event interface
Replace channel fields with frequency fields in ACS completed event
interface from the driver layer. Use
QCA_WLAN_VENDOR_ATTR_ACS_PRIMARY_FREQUENCY and
QCA_WLAN_VENDOR_ATTR_ACS_SECONDARY_FREQUENCY attributes if the driver
includes them in the QCA_NL80211_VENDOR_SUBCMD_DO_ACS event, otherwise
use QCA_WLAN_VENDOR_ATTR_ACS_PRIMARY_CHANNEL and
QCA_WLAN_VENDOR_ATTR_ACS_SECONDARY_CHANNEL attributes to maintain
backwards compatibility with old drivers.

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.

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.

Before my change I was getting "disassociated" on a wrong interface:

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 WPA: pairwise key handshake completed (RSN)

1db718b3ce nl80211: Test vendor command and event
This adds testing code (for CONFIG_TESTING_OPTIONS=y builds only) to
send an nl80211 vendor command and report a test vendor event in case
the driver supports this.

dcf8fbc058 nl80211: Simplify event processing error paths
These are practically unreachable code since cfg80211 fills in the
required attributes or does not send the event. Keep the checks in
place, but minimize the extra code in wpa_supplicant/hostapd.

7c4027f604 nl80211: Report new station / assoc event for the correct BSS
drv->ctx always points to the first BSS and we should report event using
BSS related to the interface we got NL80211_CMD_NEW_STATION from.
This fixes STA association for drivers using NL80211_CMD_NEW_STATION and
multiple virtual interfaces.

Before:
nl80211: Drv Event 19 (NL80211_CMD_NEW_STATION) received for wlan0-1 (ifindex:7)
nl80211: New station 02:00:00:00:01:00
wlan0: STA 02:00:00:00:01:00 IEEE 802.11: associated

After:
nl80211: Drv Event 19 (NL80211_CMD_NEW_STATION) received for wlan0-1 (ifindex:7)
nl80211: New station 02:00:00:00:01:00
wlan0-1: STA 02:00:00:00:01:00 IEEE 802.11: associated

This is not applicable to the cases where authentication (AP SME & MLME)
is in hostapd and hostapd_assoc_cb() instead of hostapd_notif_assoc()
handles BSS selection.

This commit introduces a QCA vendor command that allows interrogation of
the vendor-specific features supported by the device/driver. Currently
the only defined feature is the ability to offload key management.

0d4e3d1d13 nl80211: Ignore Connect failure for the previous association
Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).

This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

10bbe8b8ed nl80211: Fix a copy-paste error in key offload management
Commit b41f26845a ('Add support for
offloading key management operations to the driver') used incorrect
variable for determining the KCK length. This does not get triggered in
normal use cases since KCK and KEK are always included and of the same
length (in currently supported key management cases). Anyway, this needs
to be fixed to check the correct attribute. (CID 74491)
