Do not start SAE authentication from scratch when the AP requests
anti-clogging token to be used. Instead, use the previously generated
PWE as-is if the retry is for the same AP and the same group. This saves
unnecessary processing on the station side in case the AP is under heavy
SAE authentiation load.

Remove groups 25 (192-bit Random ECP Group) and 26 (224-bit Random ECP
Group) from the default SAE groups in station mode since those groups
are not as strong as the mandatory group 19 (NIST P-256).
In addition, add a warning about MODP groups 1, 2, 5, 22, 23, and 24
based on "MUST NOT" or "SHOULD NOT" categorization in RFC 8247. All the
MODP groups were already disabled by default and would have needed
explicit configuration to be allowed.

According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).
It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.
In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).
Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.
Only wps_pbc is supported.
This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.
Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

This speeds up P2P responses to frames received on an operating channel
in case there is an ongoing P2P listen operation on another channel.
This is applicable to drivers that support multiple channels in
concurrently.
This addresses an issue showing up in the
p2ps_channel_active_go_and_station_different_mcc test case where the
Provision Discovery Request frame can be received on the operating
channel of a group instead of the Listen channel. The response was
delayed until the listen operation timed out and this took too long time
for the peer to receive the response.

Extend wpa_psk_file to allow an optional VLAN ID to be specified with
"vlanid=<VLAN ID>" prefix on the line. If VLAN ID is specified and the
particular wpa_psk_file entry is used for a station, that station is
bound to the specified VLAN. This can be used to operate a single
WPA2-Personal BSS with multiple VLANs based on the used passphrase/PSK.
This is similar to the WPA2-Enterprise case where the RADIUS server can
assign stations to different VLANs.

If the DPP_LISTEN command failed due to the driver rejecting the
remain-on-channel request, wpa_s->dpp_listen_freq was left set to the
requested listen frequency and this resulted in the next DPP_LISTEN for

the driver was not really listening on that frequency. Fix this by

This reverts commit 2564184440.
Commit 2564184440 ("mesh: Apply channel attributes before setup
interface") triggers some channel configurations to result in leaking
memory. This seems to be caused by hapd->started not getting set when
going through a callback to start hostapd operation (e.g., when using
HT40 coex scan) due to hostapd_setup_bss() not getting called. This
results in hostapd_free_hapd_data() not clearing allocated
hapd->wpa_auth. This can be reproduced with the hwsim test case
mesh_secure_ocv_mix_legacy.
A more complete cleanup of the pending mesh patch for DFS support seems
to be needed to fix this properly, so the best approach for now is to
revert this patch and bring it back once rest of the mesh changes are
ready to be applied.
