8c41734e5d FT: Fix Reassociation Request IEs during FT protocol
The previous implementation ended up replacing all pending IEs prepared
for Association Request frame with the FT specific IEs (RSNE, MDE, FTE)
when going through FT protocol reassociation with the wpa_supplicant
SME. This resulted in dropping all other IEs that might have been
prepared for the association (e.g., Extended Capabilities, RM Enabled
Capabilities, Supported Operating Classes, vendor specific additions).

Fix this by replacing only the known FT specific IEs with the
appropriate values for FT protocol while maintaining other already
prepared elements.

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.

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

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

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

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.

CCMP group cipher was removed if CCMP was not allowed as a pairwise
cipher when loading a configuration file (but not actually when changing
configuration during runtime). This is needed to avoid issues with
configurations that use the default group cipher (TKIP CCMP) while
modifying pairwise cipher from the default CCMP TKIP) to TKIP. However,
there is not really a need to remove the CCMP group cipher if any GCMP
or CCMP cipher is enabled as a pairwise cipher.

Change the network profile validation routine to not remove CCMP as
group cipher if CCMP-256, GCMP, or GCMP-256 is enabled as a pairwise
cipher even if CCMP is not.

37547ad63c wpa_supplicant: Increase authentication timeout if CAC is started
Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).

Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).

Tested with nl80211 DFS offload implementation.

d89edb6112 wpa_supplicant: Don't reply to EAPOL if pkt_type is PACKET_OTHERHOST
When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.

This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

This comment says that this flag is used only if Wi-Fi controller has

Also it contradicts with usage of similiar p2p_mgmt field in struct
wpa_supplicant. Again struct wpa_supplicant::p2p_mgmt is set only for
dedicated P2P-device interface.

d53401c54b dbus: Redirect signal processing to the management device if present
This fixes sending of FindStopped, GroupFormationFailure, and
InvitationReceived signals in the case of separate P2P-Device interface.
This extends the coverage of the earlier commit
745d62322b ("dbus: Redirect P2P request to
the managment device if present") to these three functions that were
missing the redirection.

Some wireless controllers might have separate P2P-Device interface, see
as example result of 'iw dev':

phy#0
        Unnamed/non-netdev interface
                ...
                type P2P-device
                ...
        Interface wlp2s0
                type managed
                ...

In this case there is separate 'struct wpa_supplicant' created for this
p2p-dev-* device as result of 'wpa_supplicant_add_iface >
wpas_p2p_add_p2pdev_interface > wpa_supplicant_add_iface'.

This instance of wpa_supplicant is not registered in D-Bus
(wpas_dbus_register_*) since for corresponding P2P device interface flag
'struct wpa_interface > p2p_mgmt' is set.

But this instance is saved in p2p_init_wpa_s and is used for handling
P2P related D-Bus commands. Therefore we should look for D-Bus path in
the parent of p2p_init_wpa_s instance.

Without this change test dbus_p2p_discovery starts failing if we set
support_p2p_device in vm-run.sh.

45f7574d31 Propagate the EAP method error code
In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a
general failure parameter string "failure". This parameter is used for a
notification on the dbus.

This commit reports the EAP method failure error code in a separate
callback.

The solution in this commit is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
commit only implements the reporting for EAP-SIM and EAP-AKA methods
where the Notification Code (in AT_NOTIFICATION) is used as the method
specific error code value.

 WPA: Send EAPOL(version=1 secure=0 mic=0 ack=1 install=0 pairwise=1 kde_len=22 keyidx=0 encr=0)

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.

Add a new driver event that notifies of MAC address changes while the
interface is active.

aca4d84e3d DPP: Use wildcard BSSID in GAS query frames
Force use of the wildcard BSSID address in GAS query frames with DPP
regardless of how the gas_address3 configuration parameter is set. DPP
specification mandates this and the use of GAS here is really outside
the context of a BSS, so using the wildcard BSSID makes sense even for
the corner case of Configurator running on a known AP (where IEEE 802.11
standard would allow the BSSID of the AP to be used).

If a DPP_STOP_LISTEN call happens to be received when there is a pending
gas-query radio work that has not yet been started, it was possible for
gas_query_stop() to go through gas_query_done() processing with
gas->work == NULL and that ended up with the pending GAS query getting
freed without removing the pending radio work that hold a reference to
the now freed memory. Fix this by removing the pending non-started radio

a0bf1b68c0 Remove all PeerKey functionality
This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.

This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.

Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

f516090228 P2P: Prefer 5/60 GHz band over 2.4 GHz during GO configuration
Previously, wpas_p2p_select_go_freq_no_pref() ended up selecting a 2.4
GHz band channel first before even considering 5 or 60 GHz channels.
This was likely done more or less by accident rather than by design when
the 5 GHz and 60 GHz band extensions were added. It seems reasonable to
enhance this by reordering the code to start with 5 and 60 GHz operating
classes and move to 2.4 GHz band only if no channel was available in 5
or 60 GHz bands for P2P GO use.

This does have some potential interop issues with 2.4 GHz only peer
devices when starting up an autonomous GO (i.e., without there being
prior knowledge of channels that the peers support). Upper layers are
expected to enforce 2.4 GHz selection if that is needed for some use
cases.

will write mesh_rssi_threshold (since it has a non-default value) and
later fail to read the network block.

Fix this by moving the write code under #ifdef CONFIG_MESH as well.

2efc672075 Fix RSN pre-authentication regression with pre-connection scan results
The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.

Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.

922dcf1b45 RRM: Remove duplicate frequencies from beacon report scan request
When setting the frequencies for beacon report request scan, it is
possible that a frequency is added twice (e.g., when the same channel
appears both in the channel field and in the AP channel report
subelement). This may cause the scan request to fail.
Make sure the frequencies array contains no duplications before
requesting the scan.

 1. Reporting conditions is not supported.
 2. No valid channels found for the measurement

Sending a response with an incapable indication will stop the AP from

51143af7e7 wpa_cli: Fix global control interface for STA-FIRST/STA-NEXT
If global control interface is used and wlan doesn't support P2P,
   wpa_s->global->p2p == NULL, and log shows:

wpa_supplicant: nl80211: Failed to create a P2P Device interface p2p-dev-wlan0

Then STA-FIRST/STA-NEXT is not going to redirect to any interface,
making update_stations(ctrl_conn) is stuck in never-ending loop:

23eead4d74 RRM: Filter scan results by parent TSF only if driver supports it
Scan results with parent TSF older than the scan start TSF are not added
to the beacon report since they are considered as scan results from
previous scans. However, for drivers that report the scan start TSF but
not the parent TSF of each scan result, the parent TSF will be zero so
valid scan results will be dropped.

Fix this by filtering scan results by the parent TSF only if the
driver supports reporting the parent TSF for each scan result.

supports DFS offload, the frequency was rejected in
wpas_p2p_init_go_params(). However, it was accepted in
wpas_p2p_select_go_freq() and wpas_p2p_group_add(). To make the behavior
consistent, the DFS frequency is now accepted in
wpas_p2p_init_go_params() similar to the way done in
wpas_p2p_select_go_freq().

Redundant check in wpas_p2p_group_add() for DFS forced frequency is

Commit 5538fc9309 ('FILS: Track completion

for calling wpa_supplicant_event_assoc_auth() from EVENT_ASSOC handling
in case of FILS-completion with driver-based-SME. However, that checked
what placed outside the data != NULL case while data != NULL needs to
apply for this case as well due to wpa_supplicant_event_assoc_auth()
behavior. Move the data != NULL check to apply to both cases to avoid
potentially issues if a driver interface were to return EVENT_ASSOC
without the associate data. (CID 164708)
