When using MAC randomization wpa_supplicant can change the local MAC
address during roaming scenario:
1. We attach to AP1 (with MAC1/SSID1).
2. Roaming to AP2 (with MAC2/SSID2) is started:
a) we send DEAUTH(for AP1, with MAC1)
b) we change MAC to MAC2 due to randomization
c) we start authentication for AP2
d) we get notification about DEAUTH for AP1 (which we ignore)
e) we complete association with AP2
In point 2d we completely ignore the notification which later causes
problems. This happens if the deauthentication event is generated by the
local driver (e.g., due to beacon loss) instead of AP2 sending an
explicit Deauthentication frame.
The intended behavior is as follows: during roaming we generate DEAUTH
(2a) and signal this event right away. To protect from handling of our
own DEAUTH for the 2nd time supplicant marks 'ignore_next_local_deauth'
variable. In point 2d we should receive this notification and clear the
flag but this does not happen because MAC1 in the notification is not
the current MAC address (it has been changed in 2b) so this notification
is ignored as a one with a "foreign" address.
So we end up successfully at AP2 but with 'ignore_next_local_deauth'
still set which causes problems. For example if AP2 shuts down it has
been observed on some drivers that the DEAUTH notification is generated
as a local one and since we have flag to ignore it nothing is reported
over D-Bus.
To address the problem let's store the previously used MAC address and
use it for checking for foreign address (in combination with the current
one).

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.

Commit 74818ca63f ("Process

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.

The nl_connect is initialized with the process_bss_event() handler.
However, it is used several times with the default valid handler. As a
result, if a message that is only valid for process_bss_event() is
received while the default handler is used, it will be dropped.
This has been observed in a case where during the 4-way handshake, a
Beacon frame is received on the AP side, which triggers a beacon update,
just before receiving the next EAPOL. When send_and_recv_msgs_owner() is
called for sending the NL80211_CMD_SET_BEACON command, the
NL80211_CMD_CONTROL_PORT_FRAME event is already pending. As a result, it
is received with the default handler, which drops it. Since the EAPOL
frame is dropped, the connection attempt fails.
Fix it by using the process_bss_event() handler when the nl_connect
handler is used.

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.

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

In addition, wpa_driver_nl80211_init() does not have the provision to

driver parameter "no_rrm=1" is set after the initial setup steps.
