885bbd4de3 WNM: Remove unused code from BSS TM Req generation
The url argument to ieee802_11_send_bss_trans_mgmt_request() was
hardcoded to NULL in the only caller, so this code cannot be reached.
wnm_send_bss_tm_req() construct the same frame with more generic
parameters, including option for including the URL, so
ieee802_11_send_bss_trans_mgmt_request() can be simplified.

The length of the WNM-Sleep element was not verified before using it.
This could result in reading the subfields in this element (total of

8492cc79c0 PeerKey: Remove dead code related to STSL negotiation state
The struct wpa_stsl_negotiation seemed to have been for some kind of
tracking of state of PeerKey negotiations within hostapd. However,
nothing is actually adding any entries to wpa_auth->stsl_negotiations or
using this state. Since PeerKey does not look like something that would
be deployed in practice, there is no justification to spend time on
making this any more complete. Remove the dead code now instead of
trying to figure out what it might be used for.

37e9f511eb mka: Send MKPDUs forever if mode is PSK
Issue: When 2 peers are running MACsec in PSK mode with CA
established, if the interface goes down and comes up after
time > 10 seconds, CA does not get re-established.

Root cause: This is because retry_count of both the peers
would have reached MAX_RETRY_CNT and stays idle for other to
respond. This is clear deadlock situation where peer A waits
for MKA packets from peer B to wake up and vice-versa.

Fix: If MACsec is running in PSK mode, we should send MKPDUs
forever for every 2 seconds.

9e2afe10e6 EAP-SIM: Don't use anonymous identity in phase2
The "anonymous_identity" configuration field has more than one
semantic meaning. For tunneled EAP methods, this refers to the
outer EAP identity. For EAP-SIM, this refers to the pseudonym
identity. Also, interestingly, EAP-SIM can overwrite the
"anonymous_identity" field if one is provided to it by the
authenticator.

When EAP-SIM is tunneled within an outer method, it makes sense
to only use this value for the outer method, since it's unlikely
that this will also be valid as an identity for the inner EAP-SIM
method. Also, presumably since the outer method protects the
EAP-SIM transaction, there is no need for a pseudonym in this
usage.

Similarly, if EAP-SIM is being used as an inner method, it must
not push the pseudonym identity using eap_set_anon_id() since it
could overwrite the identity for the outer EAP method.

bd6ec7f7ca Fix MAC ACL query freeing on deinit
hapd->acl_cache and hapd->acl_queries were not reset back to NULL in
hostapd_acl_deinit() when cached results and pending ACL queries were
freed. This left stale pointers to freed memory in hapd. While this was
normally followed by freeing of the hapd data, it is possible to re-use
that hapd when disabling and re-enabling an interface. That sequence
could result in use of freed memory if done while there were cached
results or pending ACL operations with a RADIUS server (especially, if
that server did not reply).

Fix this by setting hapd->acl_queries to NULL when the pending entries
are freed.

e54691106b mka: Some bug fixes for MACsec in PSK mode
Issue:
------
The test setup has 2 peers running MACsec in PSK mode, Peer A with
MAC address higher than MAC Address of peer B. Test sequence is
1. Peer B starts with actor_priority 255
2. Peer A starts with priority 16, becomes key server.
3. Peer A stops..
4. Peer A restarts with priority 255, but because of the stale values
participant->is_key_server(=TRUE) and participant->is_elected(=TRUE)
it continues to remain as Key Server.
5. For peer B, key server election happens and since it has lower MAC
address as compared to MAC address of A, it becomes the key server.
Now we have 2 key servers in CA and is not correct.

Root-cause & fix:
-----------------
When number of live peers become 0, the flags such lrx, ltx, orx,
otx, etc. need to be cleared. In MACsec PSK mode, these stale values
create problems while re-establishing CA.

This function tries to register for Beacon frames RX which fails for

b0fb2be77a Do not send GNonce in EAPOL-Key group message 1/2
While the IEEE Std 802.11-2016 is still indicating that GNonce would be
exchanged in EAPOL-Key messages (see, e.g., Figure 12-52 showing the
Send EAPOL-Key operation in the REKEYNEGOTIATING state or the sample
group key handshake in Figure 12-47), there are also examples of
describing this field as having value zero (e.g., 12.7.7.2 Group key
handshake message 1).

GNonce is used only with the Authenticator and the Supplicant does not
have any use for it, so it is better not to expose that internal value.

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.

d77f330418 FILS: Fix AES-SIV AAD for (Re)Association Request frame decryption
The hostapd processing of the AES-SIV AAD was incorrect. The design for
the AAD changed between P802.11ai/D7.0 and D8.0 from a single vector
with concatenated data to separate vectors. The change in the
implementation had missed the change in the aes_siv_decrypt() call for
the num_elem parameter. This happened to work with the mac80211
implementation due to a similar error there.

Fix this by using the correct numbers of vectors in the SIV AAD so that
all the vectors get checked. The last vector was also 14 octets too long
due to incorrect starting pointer, so fix that as well. The changes here
are not backwards compatible, i.e., a similar fix in the Linux mac80211
is needed to make things interoperate again.

bb3ea71a23 ERP: Fix rIK derivation
Unlike the EMSKname and rRK derivations, rIK derivation is actually
using the "optional data" component in the context data (see RFC 5295).
RFC 6696 defines that optional data to be the cryptosuite field for rIK.
This was missing from the previous implementation and that resulted in
incorrect rIK being derived.

In addition, the rIK Label string does not actually include the "EAP "
prefix in the way as the rRK Label in RFC 6696 does. This would also
have resulted in incorrect rIK value.

Fix rIK derivation by adding the cryptosuite value into the KDF context
data and fixing the label string. This change is not backwards
compatible and breaks all ERP use cases (including FILS shared key
authentication) with older (broken) and new (fixed)
hostapd/wpa_supplicant builds.

QCA_NL80211_VENDOR_SUBCMD_SCAN_DONE indication. This ends up considering
the scan results as being for an external scan and thus the current
ongoing scan is not removed from the radio_work. Hence, do not reset
this vendor_scan_cookie after the scan abort so that the scan completion
event gets processed properly and vendor_scan_cookie gets cleared at
that point.

510fc2dfc9 Fix AKM suite selectors for FILS and Suite B
IEEE 802.11 standard defines the suite selectors in <OUI>:<subtype>
format where OUI uses hexadecimal format and subtype decimal format.
These WLAN_AKM_SUITE_* definitions ended up getting written incorrectly
by interpretting the decimal part as hexadecimal and as such, by having
an incorrect value. However, the older RSN_AUTH_KEY_MGMT_* values were
defined with correct values and those definitions were used in most
locations.

This commit fixes the AKM suite selector values in RADIUS WLAN-AKM-Suite
attribute for FILS and Suite B. In addition, the AKM values used in
nl80211 driver configuration (NL80211_ATTR_AKM_SUITES) are fixed for the
Suite B cases.

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

fa67debf4c Fix duplicate Reassociation Request frame dropping
Relational operators (==) have higher precedence than the ternary
conditional in C. The last_subtype check for association/reassociation
was broken due to incorrect assumption about the precedence. Fix this by
adding parenthesis around the ternary conditional.

The previous implementation worked for Association Request frames by
accident since WLAN_FC_STYPE_ASSOC_REQ happens to have value 0 and when
the last receive frame was an Association Request frame, the
sta->last_subtype == reassoc check was true and non-zero
WLAN_FC_STYPE_REASSOC_REQ was interpreted as true. However, this was
broken for Reassociation Request frame. reassoc == 1 in that case could
have matched received Association Response frame (subtype == 1), but
those are not received in AP mode and as such, this did not break other
behavior apart from not being able to drop duplicated Reassociation
Request frames.

517b5f928f nl80211: Zero num_modes if nl80211_get_hw_feature_data() fails
It was possible that nl80211_get_hw_feature_data() function would return
NULL when num_modes is not set to zero. This might result in a later crash
when accessing hw.modes. This may be reproduced with hwsim oom tests, for
example, dbus_connect_oom.
Fix that by zeroing num_modes if NULL is returned.

1f0fdaf0e4 Fix race condition between AssocResp callback and 4addr event
It is apparently possible for the NL80211_CMD_UNEXPECTED_4ADDR_FRAME
event to be delivered to hostapd before the NL80211_CMD_FRAME_TX_STATUS
event for (Re)Association Response frame. This resulted in the 4-address
WDS mode not getting enabled for a STA. This could occur in particular
when operating under heavy load and the STA is reconnecting to the same
AP in a sequence where Deauthentication frame is followed immediately by
Authentication frame and the driver event processing gets delayed due to
removal of the previous netdev taking time in the middle of this
sequence.

Fix this by recording a pending item for 4-address WDS enabling if the
NL80211_CMD_UNEXPECTED_4ADDR_FRAME event would have been dropped due to
incompleted association and then process this pending item if the TX
status for the (Re)Association Response frame is received and it shows
that the frame was acknowledged.

3459381dd2 External persistent storage for PMKSA cache entries
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
02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 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
PMKSA_ADD 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30140 43100 1 0

This functionality is disabled be default and can be enabled with
CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option. It should be
noted that this allows any process that has access to the wpa_supplicant
control interface to use PMKSA_ADD command to fetch keying material
(PMK), so this is for environments in which the control interface access
is restricted.

to be updated to upper layers by P2P-DEVICE-FOUND event. It is similar
to the case when a peer changes wfd_subelems and P2P-DEVICE-FOUND event
goes to upper layers.

9a431d4932 WFD: Clear wfd_subelems when P2P peer stops sending them
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.

49aa88bb5e P2P: Clear PEER_WAITING_RESPONSE on GO Negotiation success
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.

0f5eb69f85 Use eloop timeout for post-EAP-Failure wait before disconnection
Previously, os_sleep() was used to block the hostapd (or wpa_supplicant
AP/P2P GO mode) processing between sending out EAP-Failure and
disconnecting the STA. This is not ideal for couple of reasons: it
blocks all other parallel operations in the process and it leaves a
window during which the station might deauthenticate and the AP would
have no option for reacting to that before forcing out its own
Deauthentication frame which could go out after the STA has already
started new connection attempt.

Improve this design by scheduling an eloop timeout of 10 ms instead of
the os_sleep() call and perform the delayed operations from the eloop
callback function. This eloop timeout is cancelled if the STA
disconnects or initiates a new connection attempt before the 10 ms time
is reached. This gets rid of the confusing extra Deauthentication frame
in cases where the STA reacts to EAP-Failure by an immediate
deauthentication.

ed0a4ddc22 nl80211: Update drv->ssid on connect/associate event based on BSS data
On a connect nl80211 event, wpa_supplicant uses
wpa_driver_nl80211_get_ssid() to fetch the current associated SSID to
compare to existing configurations. However,
wpa_driver_nl80211_get_ssid() uses drv->ssid, which is a cached value.
It is set when we explicitly initial a connect request using
wpa_supplicant. If the association was initiated outside of
wpa_supplicant, we need another way to populate drv->ssid. This commit
sets drv->ssid based on cfg80211 BSS information on connect/associate
nl80211 events.

Commit adcd7c4b0b ('nl80211: Support
vendor scan together with normal scan') made the drv->scan_state updates
for NL80211_CMD_NEW_SCAN_RESULTS and NL80211_CMD_SCAN_ABORTED
conditional on drv->last_scan_cmd being NL80211_CMD_TRIGGER_SCAN. This
missed the part about the possibility of last_scan_cmd == 0 and an
externally started cfg80211 scan is ending. This could leave
drv->scan_state into SCAN_STARTED state even after the scan was
completed. Consequently, hwsim test cases could get stuck in reset()
handler waiting for scan to terminate.

Fix this by updating drv->scan_state also in drv->last_scan_cmd == 0
case.

34f7c699a6 Add multicast to unicast support
This adds support for nl80211 NL80211_CMD_SET_MULTICAST_TO_UNICAST
command.

By setting the new hostapd configuration option multicast_to_unicast=1,
hostapd configures this AP to perform multicast to unicast conversion.

When enabled, all multicast packets with ethertype ARP, IPv4, or IPv6
(possibly within an 802.1Q header) will be sent out to each station once
with the destination (multicast) MAC address replaced by the station's
MAC address. Note that this may break certain expectations of the
receiver, e.g., the ability to drop unicast IP packets encapsulated in
multicast L2 frames, or the ability to not send destination unreachable
messages in such cases.

This also does not implement Directed Multicast Service (DMS).

This fixes a regression from commit
bb598c3bdd ('AP: Add support for full

STA entry when processing Authentication frames with a driver that
advertises support for full AP client state. That resulted in bypassing
PMF protections for unprotected Authentication frames with such drivers
since the TK was lost in this operation.

It is simplest to skip the STA entry clearing in this type of case
completely to leave the TK in place and to process the new
authentication exchange otherwise normally. This matches the behavior
used with the drivers that do not implement full AP client state.

7824bf77d6 nl80211: Fix get_inact_sec() returning -1 on failure
This commit fixes the nl80211 driver call get_inact_sec() to return -1
when STA inactivity time retrieval fails in i802_read_sta_data().

This was intended to be handled by initalizing the inactive_msec member
to -1 but i802_read_sta_data() assumes the data parameter is
uninitialized and memsets the entire structure, neutralizing the attempt
to distinguish between no value (-1) and a time value of 0.

This is fixed by now requiring i802_read_sta_data() callers to
initialize the data structure first (allowing get_inact_sec() to use
-1). This is a safe change because it does not change any driver API
behavior and only affects one other static function in driver_nl80211.c

Add support to differentiate between station mode FT and AP mode FT in
wpa_supplicant builds by adding CONFIG_IEEE80211R_AP that should be used
when AP mode FT support is required in addition to station mode FT. This
allows binary size to be reduced for builds that require only the
station side FT functionality.

6f551abdfc mka: Remove "channel" hacks from the stack and the macsec_qca driver
This is specific to the macsec_qca driver. The core implementation
shouldn't care about this, and only deal with the complete secure
channel, and pass this down to the driver.

Drivers that have such limitations should take care of these in their
->create functions and throw an error.

Since the core MKA no longer saves the channel number, the macsec_qca
driver must be able to recover it. Add a map (which is just an array
since it's quite short) to match SCIs to channel numbers, and lookup
functions that will be called in every place where functions would get
the channel from the core code. Getting an available channel should be
part of channel creation, instead of being a preparation step.

78a3b23060 P2P: Clear old P2PS provision data
Receiving a provision discovery request for an ASP service that
has auto accept set to false should result in a provision discovery
response with the status field set to "currently unavailable".
Having stale P2PS provision data, results in sending a response with
the status set to success because it is mistakenly referred to as the
follow-on provision discovery request.

Fix that by clearing stale P2PS provision data in the following cases:
 1. When provision discovery is complete
 2. When ASP services are flushed (in which case old ASP provisioning
    is no longer valid).
