With AP-AP communication, when hapd0 sends a packet, hapd1 can receive
it immediately and send a response. But hapd0 will only read and process
the response after it has returned from the sending context, that is
entered eloop again. So one does not need to consider the RX function of
the reply to run for the request sending hapd before the send calling
function has returned.
Previously, with intra-process communication, the packet is not
scheduled through eloop. Thus the RX handler of the reply might be run
while the sending context of the original request has not returned.
This might become problematic, e.g., when deferring a management frame
processing until an RRB response is received and then have the request
restarted and finished before the original request handling has been
stopped.
I'm not aware of any concrete bug this is currently triggering but came
across it while thinking of FT RRB AP-AP sequence numbering.
I think the non-eloop scheduling approach might be error-prone and thus
propose to model it more closely to the way the message would be
received from a socket. Additionally, this ensures that the tests model
AP-AP communication more closely to real world.
Solution: queue these packets through eloop.

If a P2P_FIND command is issued for running the initial full scan and
the attempt to start that full scan fails, the previous behavior was to
wait for the ongoing scan to complete and then continue p2p_find scan
iterations. However, this continued with the social channels scan
instead of the initial full scan. This could end up missing the full
scan completely.
Fix this by marking the full scan pending if the new scan cannot be
started immediately. Then start the initial full scan after the ongoing
scan completes before moving to social channel only scan iterations.
This applies both for the P2P_FIND_START_WITH_FULL (no specific
frequency set) and P2P_FIND_PROGRESSIVE cases since both of them start
with a single full scan round.

behavior, but the following scans include all the social channels and
the specified frequency instead of just the previously used social

As FCC DFS requirement does not explicitly mention about the validity of
the (pre-)CAC when channel is switched, it is safe to assume that the
pre-CAC result will not be valid once the CAC completed channel is
switched or radar detection is not active on the (CAC completed) channel
within a time period which is allowed (10 seconds - channel switch time)
as per FCC DFS requirement.
Use the new driver event to allow the driver to notify expiry of the CAC
result on a channel. Move the DFS state of the channel to 'usable' when
processing pre-CAC expired event. This means any future operation on
that channel will require a new CAC to be completed. This event is

case, filter the local preference list by doing an explicit validation
of the indicated channels for P2P support.
This moves the similar validation steps from two other code paths in
p2p_check_pref_chan_recv() and p2p_check_pref_chan_no_recv() into a
common filtering step in p2p_check_pref_chan() for all three cases.
This avoids issues to start the GO in cases where the preferred
frequency list from the driver may include channels that are not
currently enabled for P2P GO use (e.g., 5 GHz band in world roaming
configuration).

This adds the same changes to EAP-AKA that were previous done for

Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
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.

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

HLP implementation ended up unregistering eloop socket for

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

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

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 "

have resulted in incorrect rIK value.
Fix rIK derivation by adding the cryptosuite value into the KDF context

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

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

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

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

peer stops sending wfd_subelems and dev->info.wfd_subelems has an old

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.

AP shall reject the association using status code 43 ("Invalid AKMP").
wpa_validate_wpa_ie() now explicitly checks for this condition to meet
this requirement instead of simply ignoring the MDE based on non-FT AKM.

If the driver advertises support for setting Beacon frame data rate,
allow the user to configure this rate as part of starting the AP. Only
one Beacon frame TX rate is allowed.
Drivers advertising such support should set corresponding flag via the
NL80211_ATTR_EXT_FEATURES attribute.

Allow configuration of Beacon frame TX rate from hostapd.conf with
"beacon_rate=xx" option. The following format is used to set
legacy/HT/VHT beacon rates:
Legacy (CCK/OFDM rates):
beacon_rate=<legacy rate in 100 kbps>
HT:
beacon_rate=ht:<HT MCS>
VHT:
beacon_rate=vht:<VHT MCS>

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

In commit a25e4efc9e ('mka: Add driver op
to get macsec capabilities') I added some code to check the driver's
capabilities. This commit has two problems:
- wrong enum type set in kay->macsec_confidentiality
- ignores that drivers could report MACSEC_CAP_NOT_IMPLEMENTED, in
which case the MKA would claim that MACsec is supported.
Fix this by interpreting MACSEC_CAP_NOT_IMPLEMENTED in the same way as a
DO_NOT_SECURE policy, and set the correct value in
kay->macsec_confidentiality.

Previously, CONFIG_IEEE80211R enabled build that supports FT for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode FT is required and there is no need for AP mode FT.
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.

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.

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).

drv->in_listen should be cleared whenever the state timeout is cleared,
if they were set together. If the flag is not cleared, the

When channel switch happens, driver wrapper's internal channel
information needs to be updated so that the new frequency will be used
in operations using drv->assoc_freq. Previously, only bss->freq was
updated and the new frequency was also indicated in the EVENT_CH_SWITCH
event. This could potentially leave out couple of cases that use
drv->assoc_freq at least as a fallback mechanism for getting the current
