4383528e01 P2P: Use weighted preferred channel list for channel selection
Previously, the driver could optionally (using QCA vendor command)
provide a preferred channel list to wpa_supplicant for channel selection
during the GO negotiation. Channel selection process can be more
efficient with the information of weights and flags of the preferred
channel list that can be provided by the driver. Use a weighted
preferred channel list provided by the driver for channel selection
during GO negotiation if such a list is available.

42944de69b nl80211: Do not store no-wait TX frame cookies to be cancelled
If the TX frame operation does not request any wait time, there is not
going to be any pending wait that could be cancelled later. As such,
there is no need to store the cookie value for these cases. This removes
unnecessary cancel-TX-wait operations that would result in some extra
latency and confusing debug log entries.

This was found with the following hwsim test case sequence where the
second test was failing due to the extra latency and this commit gets
rid of that failure:

9bd9434108 nl80211: Fix send_mlme to use monitor interface only for AP interface
Use monitor interface to send_mlme only when the interface is configured
in AP mode. In multiple interface setup, one interface can be configured
in AP mode using monitor interface and another interface in station
mode. The station interface may also require sending the management
frames without using monitor interface, e.g., support external SAE
authentication to send Authentication frames without monitor interface.
This change allows sending management frames to the driver for a station
interface where the AP interface uses monitor interface.

Additionally, the monitor interface is only valid for AP mode
(nl80211_create_monitor_interface() is called in nl80211_setup_ap) so
interface type check ensures to use monitor interface only when required
by the specific interface.

ab89291928 nl80211: Use process_bss_event() for the nl_connect handler
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.

41fae6e0bb nl80211: Add missing WPA3-SAE auth_data in auth retry case
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.

74818ca63f Process QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH after NL80211_CMD_ROAM
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.
