a00d65e79f DPP: Reject invalid no-psk/pass legacy configurator parameters
Instead of going through the configuration exchange, reject invalid
legacy configurator parameters explicitly. Previously, configuring
legacy (psk/sae) parameters without psk/pass resulted in a config object
that used a zero length passphrase. With this change, that config object
is not sent and instead, either the initialization attempts is rejected
or the incoming initialization attempt is ignored.

931f7ff656 DPP: Fix GAS client error case handling
The GAS client processing of the response callback for DPP did not
properly check for GAS query success. This could result in trying to
check the Advertisement Protocol information in failure cases where that
information is not available and that would have resulted in
dereferencing a NULL pointer. Fix this by checking the GAS query result
before processing with processing of the response.

59d59eb0e0 Revert "D-Bus: Implement Pmf property"
This reverts commit adf8f45f8a.

It is basically all wrong. The Pmf property did exist, with a signature of
"s" as documented in doc/dbus.doxygen. It was synthesized from
global_fields[].

The patch added a duplicate one, with a signature of "u", in violation
of D-Bus specification and to bemusement of tools that are careful
enough:

  $ busctl introspect fi.w1.wpa_supplicant1 /fi/w1/wpa_supplicant1/Interfaces/666

two bytes of the IE header (IEEE Std 802.11-2016, 9.4.2.102). Found by

d514b50265 WNM: Collocated Interference Reporting
Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

170244a1cd SME: Fix order of WPA IE in association request
In case that the protocol used for association is WPA the WPA IE was
inserted before other (non vendor specific) IEs. This is not in
accordance to the standard that states that vendor IEs should be placed
after all the non vendor IEs are placed. In addition, this would cause
the low layers to fail to properly order information elements.

To fix this, if the protocol used is WPA, store the WPA IE and reinsert
it after all the non vendor specific IEs were placed.

c04562e67e OWE: Improve discovery of OWE transition mode AP
An OWE AP device that supports transition mode does not transmit the
SSID of the OWE AP in its Beacon frames and in addition the OWE AP does
not reply to broadcast Probe Request frames. Thus, the scan results
matching relies only on Beacon frames from the OWE open AP which can be
missed in case the AP's frequency is actively scanned.

To improve the discovery of transition mode APs, include their SSID in
the scan command to perform an active scan for the SSIDs learned from
the open mode BSSs.

cf94626c50 OWE: Do not try to enable PMF for non-RSN associations
Explicitly set the PMF configuration to 0 (NO_MGMT_FRAME_PROTECTION) for
non-RSN associations. This specifically helps with OWE transition mode
when the network block is configured with PMF set to required, but the
BSS selected is in open mode. There is no point to try to enable PMF for
such an association.

This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could
cause such drivers to reject the connection in OWE transition mode.

af835d75b7 FILS: Fix FILS connect failures after ERP key invalidation
If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.

Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

20c2ea412a wpa_supplicant: Fix parsing of max_oper_chwidth
The max_oper_chwidth is parsed in wpa_config_set as INT_RANGE (see
ssid_fields). The actual parsing for INT_RANGE is done by
wpa_config_parse_int which can only store the result as full integer.

max_oper_chwidth is stored as u8 (a single byte) in wpa_ssid. This means
that on little endian systems, the least significant byte of the parsed
value are really stored in the max_oper_chwidth. But on big endian
system, the only most significant byte is stored as max_oper_chwidth.
This means that 0 is always stored because the provided range doesn't
allow any other value for systems with multi-byte-wide integers.

This also means that for common systems with 4-byte-wide integers, the
remaining 3 bytes were written after the actual member of the struct.
This should not have influenced the behavior of succeeding members
because these bytes would have been part of the padding between the
members on most systems.

Increasing its size to a full int fixes the write operations outside of
the member and allows to use the max_oper_chwidth setting on big endian
systems.
