2971da270f P2P: Do not use wait_time for SD Response TX for last fragmentation
The last SD Response frame fragment is not going to be followed by
another Action frame from the peer, so remove the 200 ms wait time from
the offchannel TX command in that case. This avoids leaving a 200 ms
lock on the radio to remain on the channel unnecessarily.

This is similar to commit 7655bd7388

c5fee1604b FT: Schedule wpa_ft_rrb_rx() through eloop in intra-process communication
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.

775e986d5f hostapd: Fix crash on consecutive channel switch failures
With multiple interface like AP and station which is already
associated to some other AP, when we try to do channel switch
for the AP mode (different from the operation channel support of
station) and if the AP channel switch fails continously (including
the fallback channel switch), results in a crash due to NULL pointer
dereference. This is because hostapd_deinit_driver() assigns the
driver context (drv_priv) to NULL as we are not able to bring up
the interface with a new channel

2c0ac6d613 P2P: Run full P2P_FIND scan after pending scan completes
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

7cbb5f1a44 DFS: Handle pre-CAC expired event
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
applicable only when DFS is not offloaded to the kernel driver.

79329ae0aa P2P: Verify local driver preferred frequencies for P2P use cases
Previously the peer operating channel preference was accepted if the
indicated frequency was listed in the local preference list from the
driver. This was assuming that the driver included only channels that
are currently enabled for GO operation. Since that might not be the
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).

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

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.

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.

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

This functionality is disabled by default and can be enabled with

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.

compilers even warn about it.

2977f5193a GAS: Remove unnecessarily duplicate gas_frag_limit configuration
The actual BSS configuration parameter can be updated with the SET
control interface command, so there is no need to maintain a separate
per-BSS parameter and a separate control interface handling for this.

1940559ea4 FT: Drop FT Action frames if ft_over_ds=0
Previously, the hostapd ft_over_ds parameter was used to only advertise
whether FT-over-DS is enabled in MDE and leave it to the stations to
follow that advertisement. This commit extends this to explicitly reject
(silently drop) FT Action frames if a station does not follow the
advertised capabilities.
