This is mainly to help with fuzz testing that could generate overly long
test data that would not be possible in real use cases due to MMPDU size
limits. The implementation for storing vendor IEs with such
unrealisticly long IE buffers can result in huge number of memory
reallozations and analyzing those can be very heavy.
While the maximum length of the fuzzing test input could be limited, it
seems nicer to limit this IE storage limit instead to avoid timeouts
from fuzz test runs.

Parsing and copying of WPS secondary device types list was verifying
that the contents is not too long for the internal maximum in the case
of WPS messages, but similar validation was missing from the case of P2P
group information which encodes this information in a different
attribute. This could result in writing beyond the memory area assigned
for these entries and corrupting memory within an instance of struct
p2p_device. This could result in invalid operations and unexpected
behavior when trying to free pointers from that corrupted memory.

Add support for PASN authentication with FT key derivation:
- As IEEE P802.11az/D2.6 states that wrapped data is optional and
is only needed for further validation of the FT security parameters,
do not include them in the first PASN frame.
- PASN with FT key derivation requires knowledge of the PMK-R1 and
PMK-R1-Name for the target AP. As the WPA state machine stores PMK-R1,
etc. only for the currently associated AP, store the mapping of
BSSID to R1KH-ID for each previous association, so the R1KH-ID
could be used to derive PMK-R1 and PMK-R1-Name. Do so instead
of storing the PMK-R1 to avoid maintaining keys that might not
be used.

Add support for new channels 173 and 177 in the operating classes 125 to

The operating class 129 includes channels with a maximum bandwidth of
160 MHz with center frequency index 50 and 114. The previous definition
of operating class 129 considered the center frequency index as actual
channels resulting in incorrect channel setup for the operating class.
Fix the definition of operating class 129 to consider channels with the
center frequency index of 50 and 114.
Also update the comment that describes the channel selection for

After sending DPP Auth Response, the Responder might not receive the
Auth Confirm either due to the Initiator not sending it or the reception
of the frame failing for some reason (e.g., Responder having already
left the negotiation channel). If this happens, following initiation
attempts would fail since the consecutive Auth Request would get
discarded since the previous authentication is still in progress.
Terminate DPP authentication on Responder, if no Auth Confirm is
received within one second of successfully sending Auth Response. This
allows the Responder to accept start of a new exchange.

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*().
