This was previously handled for the case where the non-success
Invitation Response frame was sent out during the Listen phase. However,
in the case the Action frame TX ended up getting scheduled when the
Search phase scan had already started (e.g., due to the driver reporting
Invitation Request RX late enough for the Listen-to-Search transition
having already started), the postponed Action frame TX status processing
did not cover the specific case of non-success Invitation Response. This
could result in the p2p_find operation getting stopped (stuck in SEARCH

Fix this by calling p2p_check_after_scan_tx_continuation() from
Invitation Response TX callback handler if the invitation was rejected.

The Secure bit in the Key Information field of EAPOL-Key frames is

done for other frames, but not for the EAPOL-Key Request frame where
supplicant is requesting a new PTK to be derived (either due to Michael
MIC failure report Error=1 or for other reasons with Error=0). In
practice, EAPOL-Key Request frame is only sent when there is a PTK in

This patch add functionality of mesh SAE PMKSA caching. If the local STA
already has peer's PMKSA entry in the cache, skip SAE authentication and
start AMPE with the cached value.
If the peer does not support PMKSA caching or does not have the local
STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry
of the peer will be removed. Then STA retries with ordinary SAE
authentication.
If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use
duration(sec). Throughout the duration, the local STA can start SAE
authentication triggered by NEW_PEER_CANDIDATE even though

In scenarios where only DFS channels are available (e.g., outdoor,
special country codes), hostapd must be able to handle situations
where all are unavailable.
The two possibilities to get there are
1) while operating on the last available DFS channel a radar is
detected
2) hostapd is started while all channels are unavailable
In both cases, hostapd instead of terminating should better
wait for the NOPs to pass and re-try operation after the CAC.
This patch provides that feature by using the condition
(iface->state == HAPD_IFACE_DFS && !iface->cac_started)
as NOP mode signature to retry operation from within
hostapd_dfs_nop_finished().

Upon receiving FST setup request on old band, the peer is searched on
new band. The assumption is that MB IE from this peer on new band
previously received either in assoc event or in FST setup request.
There are cases in which above assumption doesn't work, peer is not
found and session setup fails. For example:
- STA connects over 11ac. Due to driver limitation, MB IE is not included
in assoc event
- STA connects over 11ad. MB IE included in assoc event.
- FST session established on 11ac band, with AP as initiator. i.e. FST
setup request sent in AP=>STA direction. STA searches for peer's (AP)
MB IE on 11ad band which exists.
- FST switch occur
- FST session established on 11ad band, with STA as initiator. i.e. FST
setup request sent in STA=>AP direction. AP searches for peer's (STA)
MB IE on 11ac band which are absent.
For fixing the above, consider also peers without MB IE as candidates in

Hashing takes quite some time (can be about one second on a low-power
CPU for each passphrase provided), so hostapd can easily hit the 900 ms

be fixed by storing the passphrase instead of PSK with the STA and defer
the hashing into the WPA/RSN 4-way handshake, when enumerating all PSKs.

per-STA passphrases and this passphrase is delivered as part of the MAC

A malicious station could try to do FT-over-DS with a non WPA-enabled
BSS. When this BSS is located in the same hostapd instance, internal RRB
delivery will be used and thus the FT Action Frame will be processed by
a non-WPA enabled BSS. This processing used to crash hostapd as
hapd->wpa_auth is NULL. If the target BSS is on a different hostapd
instance, it will not listen for these packets and thus not crash.

The FT RRB hostapd packets have a length field. For PULL frames, it
counted the bytes starting with nonce and up to the last before pad. For
RESP frames, it counted the bytes starting with nonce and up to the last
before pad except for 2 bytes. For PUSH frames, it counted the bytes
starting with nonce and up to including pad.
As rounding is done with AES encryption, including pad does not make
sense. Not including the last field before pad does not make sense
either. These were broken in the earlier addition of the 2 octet
pairwise field in commit 1b484d60e5 ('FT:
Include pairwise cipher suite in PMK-R0 SA and PMK-R1 SA').
AES encryption is not affected, as rounding hides the differences. The
packets data_length field is not used, so the differences have no effect
there.
This patch changes the constants to match the bytes used, thus excluding
the pad. To validate the changes, look at remainder modulo 8 of the sum
of the size constants and the padding sizes.

Previously, stations were added to the driver only after the
(Re)Association Response frame was acked. In the time period between the
station has acked the (Re)Association Response frame and the time the
station was added to the kernel, the station can already start sending
Data frames, which will be dropped by the hardware/driver. In addition
to the data loss, the driver may ignore NDPs with PM bit set from this
STA.
Fix this by setting/adding the STA with associated flag set to the
driver before the AP sends the (Re)Association Response frame with
status success. If the (Re)Association Response frame wasn't acked,
remove the station from the driver.
Note that setting a station to associated state before the non-AP
station acknowledges the (Re)Association Response frame is not compliant
with the IEEE 802.11 standard that specifically states that a non-AP
station should transition to authenticated/associated state only after
it acknowledged the (Re)Association Response frame. However, this is a
justifiable simplification to work around the issue described above since
1. The station will be removed in case it does not acknowledge the
(Re)Association Response frame.
2. All Data frames would be dropped until the station is set to
authorized state and there are no known issues with processing the
other Class 3 frames during the short window before the
acknowledgement is seen.

Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.
The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.
New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.
When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.
To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.
Though not depended on by the code, vlan_id assignment ensures:
* vlan_id = 0 will continue to mean no AP_VLAN interface
* vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
with no per_sta_vif and no extra tagged vlan.
* vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.
This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.
DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.
MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.
Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).
Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.
The function wpa_scan_res_match() was modified to match BSS according to

When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.

still in PLINK_ESTAB state.

Setting a long off channel wait time for P2P Action frames when
we know we are already on the right channel may cause a delay in
sending the Action frame (because the driver may not be able to
satisfy the request for long wait time until previous off channel
requests are over). This may be crucial for P2P response frames
that must be sent within 100 milliseconds of receiving the request.
Fix this by adjusting P2P Action frame wait times as follows:
1. For GO Negotiation Response frame, shorten the wait time to 100 ms.
This is reasonable because the peer has just sent us the GO
Negotiation Request frame, so it is known to be on the right
channel and is probably ready to send us the GO Negotiation
Confirmation frame without delay.
2. For GO Negotiation Confirmation, P2P Invitation Response, and
Provision Discovery Response frames, there is no need for wait
time at all as this is the last frame in the exchange. So set
the wait time to 50 ms to ensure there is enough time to send the
frame.

If wpa_supplicant was first configured with PKCS #12 -based client
certificate chain and then used with another network profile that used a
different certificate chain from a X.509 certificate PEM file instead of
PKCS#12, the extra certificate chain was not reconstructed properly with
older versions of OpenSSL that 1.0.2. This could result in the
authentication failing due to the client certificate chain not being
complete or including incorrect certificates.
Fix this by clearing the extra certificate chain when setting up a new
TLS connection with OpenSSL 1.0.1. This allows OpenSSL to build the
chain using the default mechanism in case the new TLS exchange does not
use PKCS#12.
The following hwsim test case sequence was able to find the issue:

Offloading of ACS to the driver changed the design a bit in a way that
iface->current_mode could actually be NULL when the offloaded ACS
mechanism supports band selection in addition to channel selection. This
resulted in a combination that is too complex for static analyzers to
notice. While acs_init() can be called with iface->current_mode == NULL
that is only in the case where WPA_DRIVER_FLAGS_ACS_OFFLOAD is in use.
In other words, the actual ACS functions like acs_cleanup() that would
dereference iface->current_mode are not used in such a case.
Get rid of static analyzer warnings by explicitly checking
iface->current_mode in acs_init() for the case where ACS offloading is

There was a race condition in how the l2_packet sockets got read that
could result in the same socket (e.g., non-bridge) to process both the
EAP-Success and the immediately following EAPOL-Key msg 1/4 instead of
each frame going in alternative order between the bridge and non-bridge
sockets. This could be hit, e.g., if the wpa_supplicant process did not
have enough CPU to process all the incoming frames without them getting
buffered and both sockets reporting frames simultaneously.
This resulted in the duplicated EAP-Success frame getting delivered
twice for processing and likely also the EAPOL-Key msg 1/4 getting
processed twice. While the latter does not do much harm, the former did
clear the EAP authentication state and could result in issues.
Fix this by extended the l2_packet Linux packet socket workaround for
bridge to check for duplicates against the last two received frames
instead of just the last one.

It was possible for the packet socket on the bridge interface to receive
own transmitted frames between the bridge and non-bridge sockets
receiving the same incoming frame from a foreign host. This resulted in
the hash checksum validation step failing to notice a duplicate RX due
to the own frame updating the store hash value.
The own frame did get dropping in RX EAPOL processing, but that was too
late to address the issue with duplicate RX. Fix this by dropping own
frames already in l2_packet layer before checking and updating the last
RX hash value.

This was reported to fail with Windows 2012r2 with "Invalid Compound_MAC

through inner EAP method (EAP-MSCHAPv2 in the reported case) even when
using PEAP fast-reconnect. This seems to be against the [MS-PEAP]
specification which claims that inner EAP method is not used in such a
case. This resulted in a different CMK being derived by the server (used
the version that used ISK) and wpa_supplicant (used the version where
IPMK|CMK = TK without ISK when using fast-reconnect).
Fix this interop issue by making wpa_supplicant to use the
fast-reconnect version of CMK derivation only when using TLS session
resumption and the server having not initiated inner EAP method before
going through the cryptobinding exchange.

The previous behavior of bursting out all retry attempts of an SD Query
frame during a single search/listen iteration does not look very helpful
in the case where the peer does not ACK the query frame. Since the peer
was found in the search, but is not ACKing frames anymore, it is likely
that it left its listen state and we might as well do something more
useful to burst out a significant number of frames in hopes of seeing
the peer.
Modify the SD Query design during P2P Search to send out only a single
attempt (with likely multiple link-layer retries, if needed) per
search/listen iteration to each peer that has pending SD queries. Once
no more peers with pending queries remain, force another Listen and
Search phase to go through before continuing with the pending SD
queries.

rsn_pairwise) was set since encr type was selected from the union of
wpa_pairwise and rsn_pairwise. This could result in the Enrollee
receiving a Credential that it could then not use with the AP.
Fix this by masking the encryption types separately on AP based on the

When we receive FST Setup Request when session already exists, the
following validations take place:
1. we drop the frame if needed according to MAC comparison
2. we drop the frame if the session is "not pending", i.e., if FST
Setup Response was already exchanged (sent or received).
There are two issues with the above:
1. MAC comparison is relevant only before the Setup Response exchange.
In other words, Setup Request should not be dropped due to MAC
comparison after Setup Response has been exchanged.
2. Receiving Setup Request after Setup Response exchange most likely
means that FST state machine is out of sync with the peer. Dropping
the Setup Request will not help solve this situation.
The fix is:
1. do MAC comparison only if session is "pending", i.e., Setup Response
was not yet exchanged.
2. In case Setup Response was already exchanged, reset our session and
handle the Setup Request as if it arrived when session doesn't exist.

Commit 986de33d5c ('Convert remaining SSID

was further modified by commit 6bc1f95613
('Use printf escaping in SSID-to-printable-string conversion') to use
printf escaping (though, even without this, wpa_ssid_txt() would have
masked characters).
This is not desired for Called-Station-Id attribute. While it is defined
as a "String", RFC 2865 indicates that "a robust implementation SHOULD
support the field as undistinguished octets.".
Copy the SSID as an array of arbitrary octets into Called-Station-Id to
avoid any kind of masking or escaping behavior. This goes a step further
from the initial implementation by allowing even the possible (but
unlikely in practical use cases) 0x00 octet in the middle of an SSID.

On systems that have multiple WLAN rfkill instances, the rfkill code
can become confused into thinking that the device was unblocked when
in fact it wasn't, because it only matches on the WLAN type.
Since it then stores the new (unblocked) state from the wrong rfkill
instance, it will never retry the failing IFF_UP operation and the
user has to toggle rfkill again, or otherwise intervene manually, in
this case to get back to operational state.
Fix this by using the existing (but unused) ifname argument when the
rfkill instance is created to match to a specific rfkill index only.
As a P2P Device interface does not have a netdev interface associated
with it, use the name of a sibling interface to initialize the rfkill

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

Modify the FST peer connection check so it won't skip peers without MB
IEs making it more permissive for peers that didn't provide MB IEs
during association request. This can be helpful, e.g., in cases where a
STA's interface connected before it was added to the FST group. This
allows the AP to receive FST Action frames and initiate session with a
STA via STA's interface that doesn't expose MB IEs.
The adjusted FST protocol is still safe, as it protects itself in many
other ways (checking band info and it's accordance to the interfaces,
Setup IDs, connection states of the interfaces involved, etc.)

When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.
In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.
Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.

Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.
Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

When multiple interfaces across mutiple radios are started using a
single instance of hostapd, they all come up at different times
depending upon how long the ACS and HT scan take on each radio. This
will result in stations (that already have the AP profile) associating
with the first interfaces that comes up. For example in a dual band
radio case (2G and 5G) with ACS enabled, 2G always comes up first
because the ACS scan takes less time on 2G and this results in all
stations associating with the 2G interface first.
This feature brings up all the interfaces at the same time. The list of
interfaces specified via hostapd.conf files on the command line are all
marked as sync interfaces. All the interfaces are synchronized in
hostapd_setup_interface_complete().
