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.

77a020a118 wpa_supplicant: Fix auth failure when the MAC is updated externally
When connecting to a WPA-EAP network and the MAC address is changed
just before the association (for example by NetworkManager, which sets
a random MAC during scans), the authentication sometimes fails in the
following way ('####' logs added by me):

 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.

8179ae3a2a DPP: Support retrieving of configurator's private key
To retain configurator information across hostapd/wpa_supplicant
restart, private key need to be maintained to generate a valid pair of
authentication keys (connector, netaccess_key, csign) for new enrollees
in the network.

Add a DPP_CONFIGURATOR_GET_KEY control interface API through which the
private key of an existing configurator can be fetched.

Command format:
DPP_CONFIGURATOR_GET_KEY <configurator_id>

The output from this command can then be used with
"DPP_CONFIGURATOR_ADD key=<hexdump>" to create the same key again.

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.

3031133983 mesh: Move writing of mesh_rssi_threshold inside CONFIG_MESH
Previously, the code that writes mesh_rssi_threshold to a network block
always executes, but the code that reads it from network block and the
code that initializes it to a default value in a new network block are
inside #ifdef CONFIG_MESH. As a result when writing a config file it
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.
Note, network blocks which already have mesh_rssi_threshold because of
the bug will still fail to read after the fix.

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.

da143f7fb9 FILS: Fix EVENT_ASSOC processing checks for driver-SME
Commit 5538fc9309 ('FILS: Track completion
with FILS shared key authentication offload') added an additional case
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)

d4d76d9835 Fix offchannel TX done handling for sequence of TX frames
There could be multiple pending TX operations and if the earlier ones
have used wait_time, but the last one did not, the driver call for
canceling pending wait was not done. This could result in the driver
getting stuck waiting for the previously scheduled wait time and not
being able to do new operations until that. Fix this by canceling the
wait if any of the past offchannel_send_action() calls since the last
offchannel_send_action_done() used non-zero wait_time.

This was showing up as issues in certain DPP Public Action frame
sequences when the same offchannel operation is used with multiple
frames and the last frame in the sequence does not need wait_time.

618aa22900 P2P: Fix p2p_in_provisioning clearing in failure case
wpa_s->p2p_in_provisioning needs to be cleared when group formation
fully completes. The change to postpone GO side handling to the first
data connection in commit 41f853235f
('P2P: Extend group formation timeout on GO to first data connection')
resulted in making this not happen in one P2P Client side case: EAP-WSC
timeout in PBC case. While that is quite special case since it requires
30 second timeout without receiving new EAPOL frames and not getting
disassociation, it can apparently happen in some cases in practice. This
would result in new P2P operations (e.g., P2P_FIND) getting rejected
until wpa_supplicant is restarted.

Fix this by clearing wpa_s->p2p_in_provisioning whenever processing a
group formation failure case. For group formation success,
wpa_s->p2p_in_provisioning is left set to non-zero value to avoid
breaking the earlier limits on the GO side.

3c2bd55f03 P2P: wpas_p2p_select_go_freq() to check for supported pref_freq
This commit is similar to the commit
783c2920cc ('P2P: Check if the pref_freq
reported by the driver supports P2P') but extends the check for
supported pref_freq to wpas_p2p_select_go_freq().

This avoids issues with P2P_GROUP_ADD ending up selecting an unexpected
channel when get_pref_freq_list() (i.e.,
QCA_NL80211_VENDOR_SUBCMD_GET_PREFERRED_FREQ_LIST) is used. Filter the
list by removing channels that do not allow P2P operation at all.
Previously, only the explicitly disallowed channels were removed and
that could have resulted in selecting an operating channel that is not
allowed for P2P and failing to complete the operation to start the
group.

76e20f4fa7 FILS: Add FILS SK auth PFS support in STA mode
This adds an option to configure wpa_supplicant to use the perfect
forward secrecy option in FILS shared key authentication. A new build
option CONFIG_FILS_SK_PFS=y can be used to include this functionality. A
new runtime network profile parameter fils_dh_group is used to enable
this by specifying which DH group to use. For example, fils_dh_group=19
would use FILS SK PFS with a 256-bit random ECP group.

13bf18eda5 WNM: Use a dynamically allocated buffer for BTM query and response
BSS transition management query and response use a large static buffer
for the frame because the candidate list may require a lot of space.
However, in most cases the actually used space will be much less than
the buffer (since the candidate list is short or completely missing).

Use a dynamically allocated buffer instead and allocate it according
to the actual space needed.

While at it, remove unneeded filling of the MAC header in the Action

This was showing up with number of hwsim P2P test cases maintaining

1d9d21f376 GAS: Add support to randomize transmitter address
Add support to send GAS requests with a randomized transmitter address
if supported by the driver. The following control interface commands
(and matching configuration file parameters) can be used to configure
different types of randomization:

"SET gas_rand_mac_addr 0" to disable randomizing TX MAC address,
"SET gas_rand_mac_addr 1" to randomize the complete TX MAC address,
"SET gas_rand_mac_addr 2" to randomize the TX MAC address except for OUI.

A new random MAC address will be generated for every
gas_rand_addr_lifetime seconds and this can be configured with
"SET gas_rand_addr_lifetime <timeout>".

41f140d386 Add hostapd options wpa_group_update_count and wpa_pairwise_update_count
wpa_group_update_count and wpa_pairwise_update_count can now be used to
set the GTK and PTK rekey retry limits (dot11RSNAConfigGroupUpdateCount
and dot11RSNAConfigPairwiseUpdateCount). Defaults set to current
hardcoded value (4).

Some stations may suffer from frequent deauthentications due to GTK
rekey failures: EAPOL 1/2 frame is not answered during the total timeout
period of currently ~3.5 seconds. For example, a Galaxy S6 with Android
6.0.1 appears to go into power save mode for up to 5 seconds. Increasing
wpa_group_update_count to 6 fixed this issue.

f47f936170 P2P: Override P2P_PEER group_capab with 0 if no matching BSS entry found
Relying on the group_capab from the P2P peer information can result in
improper information on whether the peer is currently operating as a GO.
However, there is a known implementation in Android that does this.

To reduce issues from this misuse in upper layer to try to determine
whether a specific peer is operationg a group, override the group_capab
value in P2P_PEER output with 0 if there are no BSS entries with the
peer P2P Device as a GO. This is not a perfect information since there
may not have been a recent scan on all channels, but this results in
less issues than trying to decide between new group formation and
joining an existing group based on stale or incorrect information.

Since no upper layer application is really supposed to use the
group_capab field value in P2P_PEER command, this change should not
cause any impact for properly design components and the possibility of
regressions is limited to cases that are already known to work
incorrectly in number of identifiable cases.

db5e53cb06 mesh: Fix struct hostapd_data initialization
The local custom version of allocating and initializing struct
hostapd_data within wpa_supplicant_mesh_init() is problematic. This has
already missed couple of initialization steps that are required. Instead
of trying to remember to keep this up to date, use
hostapd_alloc_bss_data() so that there is only one place for this
initialization.

This is fixing a recent issue where FILS HLP started using
hapd->dhcp_server and expected that to be initialized to -1. For the
mesh case, that did not happen and when removing the interface, the FILS
HLP implementation ended up unregistering eloop socket for
hapd->dhcp_server (= 0). This could result in missing socket callbacks
for an arbitrary socket.

4d77d80edd mesh: Add MESH_PMKSA_GET/ADD commands
These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.

The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>

The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

b98706c14b RSN IBSS: Fix TK clearing on Authentication frame RX
When wpa_supplicant was processing a received Authentication frame (seq
1) from a peer STA for which there was already a TK configured to the
driver, debug log claimed that the PTK gets cleared, but the actual
call to clear the key was actually dropped due to AUTH vs. SUPP set_key
selection. Fix this by explicitly clearing the TK in case it was set
and an Authentication frame (seq 1) is received.

This fixes some cases where EAPOL-Key frames were sent encrypted using
the old key when a peer STA restarted itself and lost the key and had to
re-join the IBSS. Previously, that state required timing out the 4-way
handshake and Deauthentication frame exchange to recover.

These parameters are global configuration parameters for wpa_supplicant

preventing the configuration update. Make this more consistent by
updating the configuration parameter as well since that is what all the

5cda350896 RRM: Move wpabuf_resize() call into wpas_rrm_report_elem()
wpabuf_resize() can handle the initial allocation of a wpabuf and all
the other callers of wpas_rrm_report_elem() were already using a pointer
to a pointer and a wpabuf_resize() call. Simplify this by resizing the
wpabuf (if needed) within wpas_rrm_report_elem() instead of having to
calculate the needed size in all the callers. Thsi is also fixing one of
the allocation sizes to use the correct size instead of a size of a
struct that has nothing to do with the allocation (but is larger than
the needed five octets, so does not break anything).

c16b9f8d33 driver: Add scan support to beacon report
Add the following parameters to scan request:
 1. Dwell time on each channel.
 2. Whether the specified dwell time is mandatory.

In addition, add to scan results info the time that the scan actually
started, and to each scan result the time the beacon/probe was received,
both in terms of TSF of the BSS that the interface that requested the
scan is connected to (if available).

Add flags to indicate whether the driver supports dwell time
configuration and scan information reporting.

This scan configuration and information is required to support beacon
report radio measurement.

6a31440b86 Fix LCI request subelement processing
Commit 4a742011ab ('wpa_supplicant: Handle
LCI request') introduced LCI request parsing in a manner that
incremented the request pointer by four within
wpas_rrm_build_lci_report() without decrementing len correspondingly.
This could potentially result in get_ie() reading four octets beyond the
buffer if a corrupted request is received. This would be applicable only
if the LCI reporting was enabled explicitly ("SET LCI ..." control
interface command).

Fix this by updating the len variable to match the request pointer
changes.
