This defines the QCA vendor interface functions to offload PASN
authentication from the driver.
The driver sends the QCA_NL80211_VENDOR_SUBCMD_PASN event requesting to
perform PASN authentication with a list of peers with which the driver
needs to do ranging. wpa_supplicant performs PASN handshake with all the
peer devices and sets the required keys using the command
QCA_NL80211_VENDOR_SUBCMD_SECURE_RANGING_CONTEXT to the driver. After
PASN handshake is completed with all requested peers, wpa_supplicant
sends consolidated status for all peers to the driver.

To support secure ranging with a random MAC address, PASN handshake is
performed with a different source MAC address from the device's own
interface address. Hence, allow PASN Authentication frames with any
foreign MAC address to further process the Authentication frames.

Commit 74818ca63f ("Process
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH after NL80211_CMD_ROAM")
added workaround to hold the pending
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH event data for up to 100 ms
in case NL80211_CMD_ROAM is not received first. The 100 ms wait period
was sufficient for most of the cases but it's observed that some times
kernel is taking more than 100 ms to process and send NL80211_CMD_ROAM
to userspace.
If NL80211_CMD_ROAM takes more than 100 ms
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH event data getting ignored
though wpa_supplicant has it. To avoid this remove timeout for
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH event data since driver
always indicates NL80211_CMD_ROAM along with
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH.
In addition, clear the pending event data when marking the interface
disconnected since the roaming information is supposed to be used only
when reassociating without a disconnection.

Android has a mechanism to extend the driver interface in vendor
specific ways. This implementation of the vendor interface is done in
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB). Extend this to allow the vendor
events to be provided to this library to facilitate the event
processing.
Introduce a new board configuration via
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB_EVENT) rather than reusing
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB) to enable this event handling in the
private library. This is to avoid compilation issues for
wpa_driver_nl80211_driver_event() with the already existing private
library implementations defined with
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB).

NL80211_CMD_ROAM indication is scheduled via a kernel work queue, while
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH is a vendor event from the
driver. Thus, a race condition can exist wherein the vendor event is
received prior to the NL80211_CMD_ROAM indication.
The processing of this vendor event depends on the NL80211_CMD_ROAM
indication to update the roamed BSS/BSSID information and thus the out
of sequence processing of these events would result in not updating the
right BSS information.
This commit adds a workaround to hold the pending
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH event for up to 100 ms in
case NL80211_CMD_ROAM is not received first.

After a disconnect command is issued, wpa_supplicant generates a
disconnection event to self and ignores the next disconnection event
coming from the driver. In a race condition in which the driver
generates a connected event due to roaming just before receiving the
disconnect command from userspace, wpa_supplicant processes the
connected event after processing the self-generated disconnection event
and enters WPA_COMPLETED state. The driver sends a disconnection event
after processing the disconnect command sent by wpa_supplicant but the
disconnection event is ignored by wpa_supplicant as the disconnection
event is considered to be a result of locally generated disconnect
command. Thus, wpa_supplicant continues to be in the connected
(WPA_COMPLETED) state though the driver is in disconnected state.
Fix this out-of-sync behavior between the driver and wpa_supplicant by
not ignoring the disconnection event from the driver because of the
locally generated disconnect command sent to the driver if there is a
connection event received after issuing the disconnect command to the
driver.

When the driver sends a CQM RSSI threshold event, wpa_supplicant queries
the driver for the signal and noise values. However, it is possible that
by that time the station has already disconnected from the AP, so these
values are no longer valid. In this case, indicate that these values are
invalid by setting them to WPA_INVALID_NOISE.
Previously a value of 0 would be reported, which may be confusing as
this is a valid value.
Since nl80211_get_link_signal() and nl80211_get_link_noise() already set
invalid values for a case of failure, just use the value set by these
functions even if they fail.

The kernel commit "mac80211: support control port TX status reporting"
seems to be delivering the TX status events for EAPOL frames over
control port using NL80211_CMD_FRAME_TX_STATUS due to incorrect check on
whether the frame is a Management or Data frame. Use the pending cookie
value from EAPOL TX operation to detect this incorrect behavior and
redirect the event internally to allow it to be used to get full TX
control port functionality available for AP mode.

In order to retransmit faster in AP mode, hostapd can handle TX status
notifications. When using nl80211, this is currently only possible with
socket control messages. Add support for receiving such events directly
over nl80211 and detecting, if this feature is supported.
This finally allows for a clean separation between management/control
path (over nl80211) and in-kernel data path.
A follow up commit enables the feature in AP mode.
Control port TX status contains the original frame content for matching
with the current hostapd code. Furthermore, a cookie is included, which
allows for matching against outstanding cookies in the future. This
commit only prints the cookie value for debugging purposes on TX status
receive.

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.
