a919a26035 Introduce and add key_flag
Add the new set_key() parameter "key_flag" to provide more specific
description of what type of a key is being configured. This is needed to
be able to add support for "Extended Key ID for Individually Addressed
Frames" from IEEE Std 802.11-2016. In addition, this may be used to
replace the set_tx boolean eventually once all the driver wrappers have
moved to using the new key_flag.

The following flag are defined:

  KEY_FLAG_MODIFY
    Set when an already installed key must be updated.
    So far the only use-case is changing RX/TX status of installed
    keys. Must not be set when deleting a key.

  KEY_FLAG_DEFAULT
    Set when the key is also a default key. Must not be set when
    deleting a key. (This is the replacement for set_tx.)

  KEY_FLAG_RX
    The key is valid for RX. Must not be set when deleting a key.

  KEY_FLAG_TX
    The key is valid for TX. Must not be set when deleting a key.

  KEY_FLAG_GROUP
    The key is a broadcast or group key.

  KEY_FLAG_PAIRWISE
    The key is a pairwise key.

  KEY_FLAG_PMK
    The key is a Pairwise Master Key (PMK).

Predefined and needed flag combinations so far are:

  KEY_FLAG_GROUP_RX_TX
    WEP key not used as default key (yet).

  KEY_FLAG_GROUP_RX_TX_DEFAULT
    Default WEP or WPA-NONE key.

  KEY_FLAG_GROUP_RX
    GTK key valid for RX only.

  KEY_FLAG_GROUP_TX_DEFAULT
    GTK key valid for TX only, immediately taking over TX.

  KEY_FLAG_PAIRWISE_RX_TX
    Pairwise key immediately becoming the active pairwise key.

  KEY_FLAG_PAIRWISE_RX
    Pairwise key not yet valid for TX. (Only usable with Extended Key ID
    support.)

  KEY_FLAG_PAIRWISE_RX_TX_MODIFY
    Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX.

  KEY_FLAG_RX_TX
    Not a valid standalone key type and can only used in combination
    with other flags to mark a key for RX/TX.

This commit is not changing any functionality. It just adds the new
key_flag to all hostapd/wpa_supplicant set_key() functions without using
it, yet.

33c8a10498 Do not select APs found on disabled channels for connection
If a channel list changed event is received after a scan and before
selecting a BSS for connection, a BSS found on a now disabled channel
may get selected for connection. The connect request issued with the BSS
found on a disabled channel is rejected by cfg80211. Filter out the BSSs
found on disabled channels and select from the other BSSs found on
enabled channels to avoid unnecessary connection attempts that are bound
to fail.

The channel list information will be updated by the driver in cases like
country code update, disabling/enabling specific bands, etc. which can
occur between the scan and connection attempt.

144314eaa7 wpa_supplicant: Send EAPOL frames over nl80211 where available
Linux kernel v4.17 added the ability to request sending control port
frames via nl80211 instead of a normal network socket. Doing this
provides the device driver with ordering information between the
control port frames and the installation of keys. This empowers it to
avoid race conditions between, for example, PTK replacement and the
sending of frame 4 of the 4-way rekeying handshake in an RSNA. The
key difference between a TX_CONTROL_PORT and normal socket send is
that the device driver will certainly get any EAPOL frames comprising
a 4-way handshake before it gets the key installation call
for the derived key. By flushing its TX buffers it can then ensure
that no pending EAPOL frames are inadvertently encrypted with a key
that the peer will not yet have installed.

Update the RSN supplicant system to use this new operation for sending
EAPOL-Key frames when the driver reports that this capability is
available; otherwise, fall back to a normal Ethernet TX.

I have tested this on DMG (11ad/ay) devices with an out-of-tree Linux
driver that does not use mac80211. Without this patch I consistently see
PTK rekeying fail if message 4/4 shares a stream with other in-flight
traffic. With this patch, and the driver updated to flush the relevant TX
queue before overwriting a PTK (knowing, now, that if there was a message
4/4 related to the key installation, it has already entered the driver
queue), rekeying is reliable.

There is still data loss surrounding key installation - this problem is
alluded to in IEEE Std 802.11-2016, 12.6.21, where extended Key ID
support is described as the eventual solution. This patch aims to at
least prevent rekeying from totally breaking the association, in a way
that works on kernels as far back as 4.17 (as per Alexander Wetzel
extended Key ID support should be possible on 5.2).

See http://lists.infradead.org/pipermail/hostap/2019-May/040089.html for
a little more context.

8759e9116a nl80211: Control port over nl80211 helpers
Linux kernel v4.17 added the ability to request sending controlled port
frames (e.g., IEEE 802.1X controlled port EAPOL frames) via nl80211
instead of a normal network socket. Doing this provides the device
driver with ordering information between the control port frames and the
installation of keys. This empowers it to avoid race conditions between,
for example, PTK replacement and the sending of frame 4 of the 4-way
rekeying handshake in an RSNA. The key difference between the specific
control port and normal socket send is that the device driver will
certainly get any EAPOL frames comprising a 4-way handshake before it
gets the key installation call for the derived key. By flushing its TX
buffers it can then ensure that no pending EAPOL frames are
inadvertently encrypted with a key that the peer will not yet have
installed.

Add a CONTROL_PORT flag to the hostap driver API to report driver
capability for using a separate control port for EAPOL frames. This
operation is exactly like an Ethernet send except for the extra ordering
information it provides for device drivers. The nl80211 driver is
updated to support this operation when the device reports support for
NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211. Also add a driver op
tx_control_port() for request a frame to be sent over the controlled
port.

This variable is not specific to any P2P group interface and since it

9ad3c12dd1 P2P: Always use global p2p_long_listen
The p2p_long_listen value was set on the control wpa_s struct while in a
lot of cases it operated on the p2p struct. Explicitly use the global
p2p_init_wpa_s struct in cases where we might not be operating on it
already.

Without this, simply starting a p2p_listen operation (e.g., using
wpa_cli) will not work properly. As the p2p_long_listen is set on the
controlling interface and wpas_p2p_cancel_remain_on_channel_cb() uses
p2p_init_wpa_s, it would not actually work. This results in
wpa_supplicant stopping listening after the maximum remain-on-channel
time passes when using a separate P2P Device interface.

af670cb418 SME: Postpone current BSSID clearing until IEs are prepared
sme_send_authentication() could fail before actually requesting the
driver to authenticate with a new AP. This could happen after
wpa_s->bssid got cleared even though in such a case, the old association
is maintained and still valid. This can result in unexpected behavior
since wpa_s->bssid would not match the current BSSID anymore.

Fix this by postponing clearing of wpa_s->bssid until the IE preparation

ad2f096609 Maintain BSS entries for 5 seconds after interface is disabled
This is targeting the case of MAC address change for an association
which may require the interface to be set down for a short moment.
Previously, this ended up flushing the BSS table that wpa_supplicant
maintained and that resulted in having to scan again if the MAC address
was changed between the previous scan and the connection attempt. This
is unnecessary extra latency, so maintain the BSS entries for 5 seconds
(i.e., the same time that the old scan results are consider valid for a
new connection attempt) after an interface goes down.

a2c1bebd43 Improve roaming logic
Currently, wpa_supplicant may roam too aggressively; the need_to_roam()
function will return early with a roaming decision if the difference in
signal level or throughput between the current and selected APs is
"sufficiently large." In particular, if the selected AP's estimated
throughput is more than 5k greater than the current AP's estimated
throughput, wpa_supplicant will decide to roam. Otherwise, if the
selected AP's signal level is less than the current AP's signal level,
or the selected AP's estimated throughput is at least 5k less than the
current AP's estimated throughput, wpa_supplicant will skip the roam.
These decisions are based only on one factor and can lead to poor
roaming choices (e.g., a roam should not happen if the selected AP's
estimated throughput meets the threshold but the current signal and
throughput are already good, whereas a roam should happen if the signal
is slightly worse but the estimated throughput is significantly better).

This change standardizes the roaming heuristic for signal strength
difference requirements and will hopefully improve user experience. The
change can be summarized as follows: based on the current signal level,
a certain roaming difficulty is assigned. Based on the selected AP's
estimated throughput relative to the current AP's estimated throughput,
the difficulty is adjusted up or down. If the difference in signal level
meets the threshold, a roam happens.

The hard-coded values were selected purely based on the previous version
of this function. They may eventually need to be fine-tuned for optimal
performance.

If the current SNR with the associated BSS is sufficiently good (better
than GREAT_SNR = 25), there is limited benefit from moving to another
BSS even if that BSS were to have a higher signal level. As such, skip

from scan results and the current BSS for such cases.

f4f7600adf Use signal_poll noise information for roaming, if available
Using average signal strength from the driver and hardcoded noise floor
does not look like an ideal design since there can be significant
differences in the driver-reported noise floor values. Furthermore, even
though the current noise floor is a snapshot from the driver, it is
common for drivers to use a noise floor value from a longer calibration
step and that should not prevent the driver provided value from being
used. This makes the comparisons of the signal strengths between the
current AP (signal_poll) and other APs (scan) more accurate.

As an example, test runs in home environment showed 5 dB difference
between the driver reported noise floor and the hardcoded value and this
could result in significant differences in estimated throughput
calculation.

7e7b23e229 Update throughput estimate for the current BSS based on signal poll
We saw that on certain platforms in certain places we keep switching
between two APs and eventually get the same RSSI. Debugging showed that
we have a very big difference between the two antennas.

Ant A can hear AP A very well (-60) but AP B very bad (-80)
Ant B can hear AP B very well (-60) but AP A very bad (-80)

When the device associates to AP A, it'll learn to use Ant A. If the
device uses one single antenna to receive the scan results, it may hear
the AP it is currently associated to on the second antenna and get bad
results. Because of that, the wpa_supplicant will roam to the other AP
and the same scenario will repeat itself:

Association to AP A (Ant A reports -60).
Scan on Ant A: AP A: -60, AP B: -80
Scan on Ant B: AP A: -80, AP A: -60 ==> ROAM.

Association to AP B (Ant B reports -60)
Scan on Ant A: AP A: -60, AP B: -80 ==> ROAM

Etc...

Improve this by querying the signal level of the current AP using
drv_signal_poll() instead of relying on the signal level that we get
from the scan results. Also update the throughput estimate based on the
likely more accurate values for the current association.

according to requests from its 20/40 MHz AP. However STA checks only 40
MHz intolerance subfield from HT Capabilities element in scan results.
Meanwhile, as per IEEE Std 802.11-2016, 11.16.12, STA should check
overlapping BSSs as well.

Note that all the required code to check overlapping BSSs did already
exist for AP mode since AP does those checks properly before operating
as 20/40 MHz BSS in the 2.4 GHz band. Use that existing code by replace
existing 40 MHz intolerance check in sme_proc_obss_scan() with the new
shared helper function check_bss_coex_40mhz().

The previous calculation of the buffer length did not take into account
the possibility of 32-octet GTK and IGTK values and it was also missing
something to cover the 16 octet keys that are supported now. Other
buffer elements were likely sufficient to cover all these cases, but
anyway, it is better to allocate sufficient size specifically for AMPE

highest link speed that the standard allows for channel bonding (CB) up
to CB4.

Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.

User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.

When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

e780b4bf20 DPP: Bootstrapping via NFC URI Record
This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.

The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.

A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.

Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC
URI in the same way as they are used for QR Code.

783a99b73d HS2.0: Skip check for roaming_consortium for NAI realm query
Previously ANQP fetch considered NAI realm query only when cred block
did not specify roaming_consortium to optimize ANQP operations (NAI
realm list can have a very long value). In certain cases, both NAI realm
and roaming_consortium are configured in credential block and this
resulted in ANQP fetch for NAI realm not being initiated. That could
result in not being able to select the highest priority available
credential/network.

Remove roaming_consortium check for NAI realm query inclusion in ANQP
request so that we will request NAI realm information whenever it can
result in matching additional networks. This makes the ANQP queries more
costly in some cases, but the additional information is needed for
correct behavior in network selection.

c349174035 MBO/OCE: Update disable_mbo_oce flag after association
After roaming to an AP, update disable_mbo_oce flag based on the current
BSS capabilities. This flag is used to check whether STA should support
MBO/OCE features and process BTM request received from the current
connected AP.

When a STA roams from a WPA2 MBO/OCE AP with PMF enabled to a
misbehaving WPA2 MBO/OCE AP without PMF, or if the driver chooses a BSS
in which PMF is not enabled for the initial connection, BTM requests
from such APs should not be processed by STA.

2e06cef80a MBO/OCE: Work around misbehaving MBO/OCE APs that use RSN without PMF
The MBO and OCE specification require the station to mandate use of PMF
when connecting to an MBO/OCE AP that uses WPA2. The earlier
implementation prevented such misbehaving APs from being selected for
connection completely. This looks like the safest approach to take, but
unfortunately, there are deployed APs that are not compliant with the
MBO/OCE requirements and this strict interpretation of the station
requirements results in interoperability issues by preventing the
association completely.

Relax the approach by allowing noncompliant MBO/OCE APs to be selected
for RSN connection without PMF to avoid the main impact of this
interoperability issue. However, disable MBO/OCE functionality when PMF
cannot be negotiated to try to be as compliant as practical with the
MBO/OCE tech spec requirements (i.e., stop being an MBO/OCE STA for the
duration of such workaround association). Also disable support for BTM
in this workaround state since MBO would expect all BTM frames to be
protected.

what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no

The commit ad9a1bfe78 ("nl80211: Share VHT channel configuration for

the mesh functionality on 2.4 GHz with HE because ibss_mesh_setup_freq()
isn't setting up the VHT parameters for 2.4 GHz.

This problem was resolved for 2.4 GHz by commit df4f959988 ("nl80211:
Don't force VHT channel definition with HE"), but it is still possible
to disable VHT during the mesh/IBSS freq setup on 5 GHz - which would
result in the same problem as seen on 2.4 GHz.

The code enabling HE for IBSS/mesh must now make sure that it doesn't
enable HE when VHT could be enforced by the nl80211 driver code but
disabled by the user.

This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to

with WPAS_MODE_*. Still some of the code sections used the
IEEE80211_MODE_* defines instead of WPAS_MODE_*.

This should have no impact on the actual code because the constants for
INFRA, IBSS, AP and MESH had the same values.

cbfd0a263d P2P: Force p2p-send-action as the next radio work to execute
This increases the priority of the p2p-send-action radio work, i.e., the
radio work used for transmitting potentially offchannel P2P Action
frames by marking it as the next radio work to execute. This is to avoid
the delay in transmissions due to already queued offchannel radio work
items in the queue. In particular, this means not having to wait for a
pending p2p-scan radio work to be executed before the new P2P Action
frame can be transmitted. This helps in avoiding timeouts on the peer
device when a P2P Action frames is received during other activity on the
device.

2e3bff5919 P2P: Reject p2p-send-action work while other one is pending
The previous implementation rejects the p2p-send-action work while there
is already one in progress (wpas_send_action_cb() has already been
called for it to start operation). Enhance the same to also consider any
p2p-send-action works pending in the radio work (i.e., waiting for that
wpas_send_action_cb() call).

This is considering the current behaviour of P2P to handle the state
corresponding to respective Action frame transmission:
pending_action_state. If a new P2P Action frame transmission is queued
while there is another one already in the queue, the transmit status of
the first frame is wrongly intepreted by the P2P state machine which has
already scheduled/queued another frame for transmission.

PMKSA. For this purpose PMKID is passed in RSNE in (Re)Association
Request frame. In the case of SAE AP, open authentication shall be used

SAE authentication.

The previous implementation correctly handles SME-in-wpa_supplicant

Fix SME-in-driver behavior by reseting authentication algorithm to

322d328e71 FT: Fix SAE + FT-SAE behavior in association parameter selection
Do not try to initialize FT reassociation if the selected AKM is for SAE
instead of FT-SAE when both of these are enabled in a network profile.
This fixes an issue with MDE being included in an (Re)Association
Request frame even when using a non-FT AKM (which is something that
results in hostapd rejecting the association).

f5db775049 Remove pending connect and sme-connect radio works on disconnect
There was a race condition in a case where a new connection attempt was
scheduled as a pending radio work and that was followed by a DISCONNECT
command before the pending radio work is started. The pending radio work
would not have been deleted in that sequence and instead, it was
executed when the radio became available next. This could result in an
unexpected connection after an explicit request to disconnect.

Fix this by removing pending connect and sme-connect radio works on

2c129a1b71 Fix cipher suite selector default value in RSNE for DMG
According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).

It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.

In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

83ebf55865 wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).

Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.

Only wps_pbc is supported.

This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.

Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

remain-on-channel request, wpa_s->dpp_listen_freq was left set to the
requested listen frequency and this resulted in the next DPP_LISTEN for
the same frequency reporting "DPP: Already listening on .." even when
the driver was not really listening on that frequency. Fix this by
clearing wpa_s->dpp_listen_freq in the error case.

3e949655cc Revert "mesh: Apply channel attributes before setup interface"
This reverts commit 2564184440.

Commit 2564184440 ("mesh: Apply channel attributes before setup
interface") triggers some channel configurations to result in leaking
memory. This seems to be caused by hapd->started not getting set when
going through a callback to start hostapd operation (e.g., when using
HT40 coex scan) due to hostapd_setup_bss() not getting called. This
results in hostapd_free_hapd_data() not clearing allocated
hapd->wpa_auth. This can be reproduced with the hwsim test case
mesh_secure_ocv_mix_legacy.

A more complete cleanup of the pending mesh patch for DFS support seems
to be needed to fix this properly, so the best approach for now is to
revert this patch and bring it back once rest of the mesh changes are
ready to be applied.

cc9c4feccc OpenSSL: Allow systemwide policies to be overridden
Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.

Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.

In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.

In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

89a7cdd690 crypto: Add option to use getrandom()
According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:

"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."

An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.

It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).

Add new configuration parameters macsec_replay_protect and
macsec_replay_window to allow user to set up MACsec replay protection
feature. Note that according to IEEE Std 802.1X-2010 replay protection
and delay protection are different features: replay protection is
related only to SecY and does not appear on MKA level while delay
protection is something that KaY can use to manage SecY state.

2fc0675683 mka: Fix lowest acceptable Packet Number (LPN) calculation and use
The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."

When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.

Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

b678ed1efc macsec: Make pre-shared CKN variable length
IEEE Std 802.1X-2010, 9.3.1 defines following restrictions for CKN:

"MKA places no restriction on the format of the CKN, save that it comprise
an integral number of octets, between 1 and 32 (inclusive), and that all
potential members of the CA use the same CKN. No further constraints are
placed on the CKNs used with PSKs, ..."

Hence do not require a 32 octet long CKN but instead allow a shorter CKN
to be configured.

This fixes interoperability with some Aruba switches, that do not accept
a 32 octet long CKN (only support shorter ones).

Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in

f9da7505bf OCV: Include and verify OCI in SA Query frames
Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.

On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.

Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.

As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.
