The sta2.scan() calls were performing full scan of all channels and
reporting only the BSS entry that happened to be the first one in the
wpa_supplicant list. This is problematic since it is possible that the
target AP was not found and incorrect BSS was selected and used for
setting scan_freq which made the connection fail. Furthermore, there is
no need to use full scan for these test cases, so use a single channel
scan instead.

If 20/40 MHz co-ex scan resulted in switching primary and secondary
channels, mesh setup failed to update the frequency parameters for
hostapd side configuration and that could result in invalid secondary
channel configuration preventing creating of the mesh network. This
could happen, e.g., when trying to set up mesh on 5 GHz channel 36 and
co-ex scan finding a BSS on channel 40. Switching the pri/sec channels
resulted in hostapd code trying to check whether channel 32 is

This adds new wpa_supplicant control interface commands PMKSA_GET and
PMKSA_ADD that can be used to store PMKSA cache entries in an external
persistent storage when terminating a wpa_supplicant process and then
restore those entries when starting a new process. The previously added
PMKSA-CACHE-ADDED/REMOVED events can be used to help in synchronizing
the external storage with the memory-only volatile storage within
wpa_supplicant.
"PMKSA_GET <network_id>" fetches all stored PMKSA cache entries bound to
a specific network profile. The network_id of the current profile is
available with the STATUS command (id=<network_id). In addition, the
network_id is included in the PMKSA-CACHE-ADDED/REMOVED events. The
output of the PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds>
<akmp> <opportunistic>
For example:
02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30240 43200 1 0

The PMKSA_GET command uses the following format:
<network_id> <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration
in seconds> <akmp> <opportunistic>
(i.e., "PMKSA_ADD <network_id> " prefix followed by a line of PMKSA_GET
output data; however, the reauth_time and expiration values need to be
updated by decrementing them by number of seconds between the PMKSA_GET
and PMKSA_ADD commands)
For example:
PMKSA_ADD 0 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30140 43100 1 0

Commit 8e84921efe ('P2P: Support driver

checking of the index only after having read a value from the array.
That could in theory read one entry beyond the end of the stack buffer.
Fix this by moving the index variable check to be done before using it
to fetch a value from the array.
This code is used only if wpa_supplicant is build with
CONFIG_DRIVER_NL80211_QCA=y and if the driver supports the vendor
extension (get_pref_freq_list() driver op). In addition, the driver
would need to return more than P2P_MAX_PREF_CHANNELS (= 100) preferred

driver is known to return that many preferred channels, so this does not

When a peer device stops sending wfd_subelems, wpa_supplicant should
remove dev->info.wfd_subelems from peer's properties. Previously,
wpa_supplicant left the previously learned dev->info.wfd_subelems in
place whenever the new message did not include wfd_subelems.
In addition to fixing the clearing of the old wfd_subelems, this
resolves another issue. As "wfd_changed" variable becomes true even when
peer stops sending wfd_subelems and dev->info.wfd_subelems has an old
value, a new P2P-DEVICE-FOUND event notification was sent again and
again to upper layers whenever a new discovery response was received
from the peer that previously advertised WFD subelements.

This makes wpa_supplicant behavior more consistent with FLUSH command to
clear all state. Previously, it was possible for an ongoing scan to be
aborted when the FLUSH command is issued and the scan results from that

table which was supposed to cleared by the FLUSH command.

The final check in this test case was issuing a new P2P_FIND command
immediately after the P2P_SERVICE_DEL command on the peer. It looked
like it was possible for the scan timing to go in a sequence that made
the new P2P_FIND operation eventually accept a cfg80211 BSS entry from
the very end of the previous P2P_FIND. This resulted in unexpected
P2P-DEVICE-FOUND event even though there was no new Probe Response frame
from the peer at that point in time.

Previously, this flag was cleared only in case of failed GO Negotiation.
That could leave the flag set for a peer and if a new group formation
was performed with the same peer before the entry expired, there was
increased risk of getting stuck in a state where neither peer replied to
a GO Negotiation Request frame if a GO Negotiation Response frame with
Status 1 was dropped.
The error sequence could happen in the go_neg_with_bss_connected test
case when timing was suitable to make the second GO negotiation drop a
pending TX Action frame if the GO Negotiation Response with Status 1 was
scheduled for transmission during a P2P scan and P2P_CONNECT was issued
before that scan got aborted.
