When wpa_supplicant sends NL80211_CMD_AUTHENTICATE to kernel, it is
possible that the cfg80211 in kernel has expired the BSS entry that
we are trying to auth with. Then cfg80211 will reject the auth cmd.
In this case, wpa_supplicant will trigger a single channel scan to
refresh cfg80211 BSS entry, and retry the auth when scan is finished.
When this case happens, wpa_supplicant makes a copy of auth params,
such as frequency, bssid, ssid, ie and so on. So when we retry auth,
the copy of these params will be used. The problem is, a param named
auth_data is missed when making the copy. The auth_data is used by
NL80211_ATTR_SAE_DATA which is a mandatory field for WPA3-SAE auth.
In WPA3-SAE case the auth retry will always fail because auth_data is
missing. This patch fixes the issue.

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.

The response for the respective TWT operations can either be synchronous
or asynchronous (wherever specified). If synchronous, the response to
this operation is obtained in the corresponding vendor command reply to
the user space. For asynchronous case, the response is obtained as an
event with the same operation type.
Drivers shall support either of these modes but not both simultaneously.
The support for asynchronous mode is advertised through the new flag
QCA_WLAN_VENDOR_FEATURE_TWT_ASYNC_SUPPORT. If the driver does not
include this flag, it shall support synchronous mode.

The earlier workaround for UBSAN issues in commit 3b6b3ae581 ("Modify
dl_list_for_each() to not use unaligned access with WPA_TRACE") ended up
using a construction in which the type cast to the containing structure
was compared instead of the struct dl_list pointers. While that worked
around the UBSAN issue, it resulted in a comparison that gcc-10
interprets as being out of bounds for struct dl_list (which it obviously
is since this is to find the start of the containing structure).
Revert that workaround and instead, mark the struct dl_list used within
struct os_alloc_trace to have matching 16 octet alignment as the
containing structure. This is also restoring consistent design for
dl_list_for_each*().

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 hostapd DFS code deinitializes and initializes the AP interface, if
a clean channel switch is not possible. In this case the AP code paths
would deinit the driver, for example nl80211, without wpa_supplicant
code paths getting notice of this.
Therefore add callbacks for wpa_supplicant mesh methods, which are
called on init/deinit of the AP BSS. These callbacks are then used to
handle the reset in the mesh code.

Mesh join function is the last function to be called during mesh join
process, but it's been called a bit earlier than it's supposed to be, so
that some mesh parameter values such as VHT capabilities were not
applied correct when mesh join is in process. Moreover, the current
design of mesh join that is called directly after mesh initialization
isn't suitable for DFS channels to use, since mesh join process should
be paused until DFS CAC is done and resumed after it's done.
The callback will be called by hostapd_setup_interface_complete_sync().
There is a possibility that completing mesh init fails, so add error
handling codes for that.
