The Multi-AP specification only specifies that information elements have
to be added to the Association Request and Association Response frame;
it doesn't specify anything about what should be done in case they are
missing. Previously, we rejected non-backhaul associations on a
backhaul-only BSS, and non-fronthaul associations on a fronthaul-only
BSS.
However, this makes WPS fail when fronthaul and backhaul are separate
SSIDs. Indeed, WPS for the backhaul link is performed on the *fronthaul*
SSID. Thus, the Association Request frmae used for WPS *will* contain
the Multi-AP IE indicating a backhaul STA. Rejecting that association
makes WPS fail.
Therefore, accept a multi-AP backhaul STA Association Request frame on a
fronthaul-only BSS. Still issue a warning about it, but only at level
DEBUG intead of INFO. Also change the condition checking to make it
clearer.
While we're at it, also fix the handling of unexpected bits in the
Multi-AP IE. 4 bits are reserved in the specification, so these
certainly have to be ignored. The specification also doesn't say that
setting one of the other bits is not allowed. Therefore, only report
unexpected values in the Multi-AP IE, don't reject because of it. Note
that a malformed IE (containing more than one byte) still triggers a
rejection.

ieee802_11_rx_wnmsleep_req() might have been called for a short frame
that has no more payload after the Public Action field, i.e., with len
== 0. The bounds checking for the payload length was done only for the
information elements while the one octet Dialog Token field was read
unconditionally. In the original implementation, this could have
resulted in reading one octet beyond the end of the received frame data.
This case has not been reachable after the commit e0785ebbbd ("Use
more consistent Action frame RX handling in both AP mode paths"), but it
is better to address the specific issue in ieee802_11_rx_wnmsleep_req()
as well for additional protection against accidential removal of the
check and also to have something that can be merged into an older
version (pre-v2.7) if desired. The comments below apply for such older
versions where the case could have been reachable.
Depending on driver interface specific mechanism used for fetching the
frame, this could result in reading one octet beyond the end of a
stack/hash buffer or reading an uninitialized octet from within a
buffer. The actual value that was read as the Dialog Token field is not
used since the function returns immediately after having read this value
when there is no information elements following the field.
This issue was initially added in commit d32d94dbf4 ("WNM: Add
WNM-Sleep Mode implementation for AP") (with CONFIG_IEEE80211V=y build
option) and it remained in place during number of cleanup and fix
changes in this area and renaming of the build parameter to
CONFIG_WNM=y. The impacted function was not included in any default
build without one of the these optional build options being explicitly
enabled. CONFIG_WNM=y is still documented as "experimental and not
complete implementation" in hostapd/defconfig. In addition, commit
114f2830d2 ("WNM: Ignore WNM-Sleep Mode Request in wnm_sleep_mode=0
case") made this function exit before the impact read if WNM-Sleep Mode
support was not explicitly enabled in runtime configuration
(wnm_sleep_mode=1 in hostapd.conf). Commit e0785ebbbd ("Use more
consistent Action frame RX handling in both AP mode paths") made this
code unreachable in practice.
Add an explicit check that the frame has enough payload before reading
the Dialog Token field in ieee802_11_rx_wnmsleep_req().

The Android-specific chmod and chown operations on the client socket
(for communication with wpa_supplicant) did not protect against file
replacement between the bind() and chmod()/chown() calls. If the
directory in which the client socket is created (depends a bit on the
version and platform, but /data/misc/wifi/sockets is commonly used)
allows write access to processes that are different (less privileged)
compared to the process calling wpa_ctrl_open2(), it might be possible
to delete the socket file and replace it with something else (mainly, a
symlink) before the chmod/chown operations occur. This could have
resulted in the owner or permissions of the target of that symlink being
modified.
In general, it would be safest to use a directory which has more limited
write privileges (/data/misc/wifi/sockets normally has 'wifi' group
(AID_WIFI) with write access), but if that cannot be easily changed due
to other constraints, it is better to make wpa_ctrl_open2() less likely
to enable this type of race condition between the operations.
Replace chown() with lchown() (i.e., a version that does not dereference
symlinks) and chmod() with fchmod() on the socket before the bind() call
which is also not going to dereference a symlink (whereas chmod()
would). lchown() is a standard operation, but the fchmod() on the socket
is less so (unspecified behavior in some systems). However, it seems to
work on Linux and in particular, on Android, where this code is
executed.

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]

The documentation in the hostapd.conf file says that the dynamic_vlan
variable is used to control whether VLAN assignments are accepted from a
RADIUS server. The implication seems to be that a static VLAN assignment
will come from the accept_mac_file if dynamic_vlan is set to 0, and a
dynamic assignment will come from the RADIUS server if dynamic_vlan is
set to 1. Instead, I'm seeing that the static settings from the
accept_mac_file are ignored if dynamic_vlan is set to 0, but used if
dynamic_vlan is set to 1. If dynamic_vlan is set to 1 and the RADIUS
server does not provide a VLAN, then the accept_mac_file assignment is
overridden and the STA is assigned to the default non-VLANed interface.
If my understanding of the expected behavior is correct, then I believe
the problem is in ap_sta_set_vlan(). That routine checks the
dynamic_vlan setting, but has no way of determining whether the incoming
vlan_desc is static (i.e., from accept_mac_file) or dynamic (i.e., from
a RADIUS server).
I've attached a patch that gets hostapd working as I believe it's meant
to, and updates the documentation to make the implicit behavior
explicit.
The functional changes are:
- hostapd_allowed_address() will always extract the vlan_id from the
accept_macs file. It will not update the vlan_id from the RADIUS cache
if dynamic_vlan is DISABLED.
- hostapd_acl_recv_radius() will not update the cached vlan_id if
dynamic_vlan is DISABLED.
- ieee802_1x_receive_auth() will not update the vlan_id if dynamic_vlan
is DISABLED.
More cosmetic:
Most of the delta is just moving code out of ieee802_1x_receive_auth()
into a new ieee802_1x_update_vlan() routine. While I initially did this
because the new DISABLED check introduced excessive indentation, it has
the added advantage of eliminating the vlan_description allocation and
os_memset() call for all DYNAMIC_VLAN_DISABLED configs.
I've done a couple rounds of review offline with Michael Braun (who has
done much of the work in this part of the code) and incorporated his
feedback.
If dynamic_vlan=0 (disabled), vlan assignments will be managed using the
local accept_mac_file ACL file, even if a RADIUS server is being used
for user authentication. This allows us to manage users and devices
independently.

exception of applications which require randomness during early boot

it will block until the entropy pool is initialized."
An attempt to use it would cause unnecessary blocking on machines

IEEE Std 802.1X-2010, 11.11 describes that the ICV is separate from the
parameter sets before it. Due to its convenient layout the ICV Indicator
'body part' is used to encode the ICV as well.
IEEE Std 802.1X-2010, 11.11.3 describes the encoding of MKPDUs. In
bullet e) is desribed that the ICV Indicator itself is encoded when the
ICV is not 16 octets in length. IEEE Std 802.1Xbx-2014, Table 11-7 note
e) states that it will not be encoded unless the Algorithm Agility
parameter specifies the use of an ICV that is not 16 octets in length.
Therefore the length calculation for the ICV indicator body part must
take into account if the ICV Indicator is to be encoded or not. The
actual encoder of the ICV body already takes care of the rest.
In practice, this change will remove the ICV Indicator parameter set (4
octets before the ICV value itself) since the only defined algorithm
agility value uses an ICV of 16 octets. IEEE Std 802.1X-2010 MKPDU
validation and decoding rules in 11.11.2 and 11.11.4 require the
receipient to handle both cases of ICV Indicator being included or not.

extends upon that by considering missing parameter sets a failure.
Two checks are added by this commit. First, verify that live peers start

The status values returned by mka_param_body_handler.body_rx functions
are currently ignored by ieee802_1x_kay_decode_mkpdu(). If a failure is
detected the KaY should (a) stop processing the MKDPU and (b) do not
update the associated peer's liveliness.
IEEE Std 802.1X-2010, Table 11-7 (MKPDU parameter sets) and 11.11.3
(Encoding MKPDUs) dictate that MKA_SAK_USE (set type 3) will always be
encoded before MKA_DISTRIBUTED_SAK (set type 4) in MKPDUs. Due to
implementation of mka_param_body_handler, the code will always decode
MKA_SAK_USE before MKA_DISTRIBUTED_SAK. When MKA_DISTRUBUTED_SAK
contains a new SAK the code should decode MKA_DISTRUBUTED_SAK first so
that the latest SAK is in known before decoding MKA_SAK_USE.
The ideal solution would be to make two passes at MKDPU decoding: the
first pass decodes MKA_DISTRIBUTED_SAK, the second pass decodes all
other parameter sets.
A simpler and less risky solution is presented here: ignore MKA_SAK_USE
failures if MKA_DISTRIBUTED_SAK is also present. The new SAK will be
saved so that the next MKPDU's MKA_SAK_USE can be properly decoded. This
is basically what the code prior to this commit was doing (by ignoring
all errors).
Also, the only real recourse the KaY has when detecting any bad
parameter set is to ignore the MKPDU by not updating the corresponding
peer's liveliness timer, 'peer->expire'.
Signed-off-by: Michael Siedzik <msiedzik@extremenetworks.com>
If a live peer ever changes its Member Identifier (MI), the KaY
correctly detects a "duplicated SCI" but then proceeds to delete the
peer without deleting the peer's resources (i.e., RxSC, RxSAs, TxSAs).
Note that a remote peer's MI will change if and when an
ieee8021XPaePortInitialize is executed on the remote port.
The solution here is to ignore all MKPDUs containing the new MI until
after the peer (that corresponds to the old MI) expires and cleans up
its resources. After the old peer is removed reception of the next MKPDU
containing the new MI will result in the creation of a new peer with the
new MI.

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).

Delay Protect and Replay Protect are two separate and distinct features
of MKA. Per IEEE Std 802.1X-2010, 9.10.1 "Delay Protect, TRUE if LPNs
are being reported sufficiently frequently to allow the recipient to
provide data delay protection. If FALSE, the LPN can be reported as
zero", and per 9.10 "NOTE--Enforcement of bounded received delay
necessitates transmission of MKPDUs at frequent (0.5 s) intervals, to
meet a maximum data delay of 2 s while minimizing connectivity
interruption due to the possibility of lost or delayed MKPDUs."
This means struct ieee802_1x_mka_sak_use_body::delay_protect should only
be set TRUE when MKPDUs are being transmitted every 0.5 s (or faster).
By default the KaY sends MKPDUs every MKA_HELLO_TIME (2.0 s), so by
default delay_protect should be FALSE.
Add a new 'u32 mka_hello_time' parameter to struct ieee802_1x_kay. If
delay protection is desired, the KaY initialization code should set
kay->mka_hello_time to MKA_BOUNDED_HELLO_TIME (500 ms).

Advertise vendor specific Multi-AP IE in (Re)Association Request frames
and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame
does not contain the Multi-AP IE, disassociate.
This adds a new configuration parameter 'multi_ap_backhaul_sta' to
enable/disable Multi-AP functionality.
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
wpa_drv_if_add(), which only gets called when an interface is added
through the control interface, not when it is configured from the
command line.

The purpose of Multi-AP specification is to enable inter-operability
across Wi-Fi access points (APs) from different vendors.
This patch introduces one new configuration parameter 'multi_ap' to
enable Multi-AP functionality and to configure the BSS as a backhaul
and/or fronthaul BSS.
Advertise vendor specific Multi-AP capabilities in (Re)Association
Response frame, if Multi-AP functionality is enabled through the
configuration parameter.
A backhaul AP must support receiving both 3addr and 4addr frames from a
backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
WEP), we can safely call hostapd_set_wds_encryption() as well and we can
reuse the entire WDS condition.
To parse the Multi-AP Extension subelement, we use get_ie(): even though
that function is meant for parsing IEs, it works for subelements.

After the network changed to a new channel, perform an SA Query with the
AP after a random delay if OCV was negotiated for the association. This
is used to confirm that we are still operating on the real operating
channel of the network. This commit is adding only the station side

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.

It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.
Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.
This fixes hwsim test case fils_sk_hlp_oom failures with unmodified
mac80211 implementation (i.e., with a relatively short retransmission
timeout for (Re)Association Request frame).

Add interface for drivers to report changes in TX/RX throughput
dynamically to user space. This information can be used by userspace
tools to tune kernel's TCP parameters in order to achieve peak
throughput. The driver may optionally provide guidance on which TCP
parameters to be configured for optimal performance along with the
values to be configured.
The TCP parameters that need to be tuned for peak performance are not
interface specific. Based on the guidance from the driver and
considering the other interfaces that may be affected with the new
configurations, a userspace tool has to choose the values to be
configured for these parameters to achieve optimal performance across
interfaces.
The throughput levels informed by the driver with this event are only
for providing guidance on TCP parameter tuning from userspace. The
driver may change the thresholds used to decide low or medium or high
throughput levels based on several parameters based on the PHY layer
capacity in the current connection, the number of packets being
dispatched per second, or the number of packets pending in queues, etc.
The throughput levels may not be consistent with the actual throughput
of the link.

Add support for negotiating WNM Collocated Interference Reporting. This

interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

Previously the file permissions for the debug log file were not

which in most cases would result in a file that is world-readable. This
is a violation of good practices, since not every user should have
access to sensitive information that might be contained in the debug log
file.
Explicitly set sane default file permissions in case the file is newly

Unfortunately the fopen(3) function does not provide such a facility, so
the approach needs to be changed in the following way:
1) The file descriptor needs to be created manually using the open(3)
function with the correct flags and the desired mode set.
2) fdopen(3) can then be used on the file descriptor to associate a file

Previous implementation ended up triggering PMF check for previous
association and SA Query procedure incorrectly in cases where there is a
STA entry in hostapd, but that STA is not in associated state. This
resulted in undesired temporary rejection of the association with status
code 30.
This ended up breaking OWE group negotiation when PMF is in use since
the check for the OWE group would have happened only after this earlier
PMF check and rejection (i.e., the station got status code 30 instead of
the expected 77).
For example, when the AP is configured with OWE group 21 and a station
tries groups 19, 20, and 21 (in this sequence), the first two
Association Request frames should be rejected with status code 77.
However, only the first one got that status code while the second one
got status code 30 due to that issue with PMF existing association
check.
Furthermore, hostapd was continuing with SA Query procedure with
unencrypted Action frames in this type of case even though there was no
existing association (and obviously, not an encryption key either).
Fix this by checking that the STA entry is in associated state before
initiating SA Query procedure based on the PMF rules.

PMKID derivation with the Suite B AKMs is a special case compared to
other AKMs since that derivation uses KCK instead of PMK as an input.
This means that the PMKSA cache entry can be added only after KCK has
been derived during 4-way handshake. This also means that PMKID would
change every time 4-way handshake is repeated even when maintaining the
same PMK (i.e., during PTK rekeying and new associations even if they
use PMKSA caching).
wpa_supplicant was previously replacing the PMKSA cache entry whenever a
new PMKID was derived. This did not match hostapd expectations on the AP
side since hostapd did not update the PMKSA cache entry after it was
created. Consequently, PMKSA caching could be used only once (assuming
no PTK rekeying happened before that). Fix this by making wpa_supplicant
behave consistently with hostapd, i.e., by adding the Suite B PMKSA
cache entries with the PMKID from the very first 4-way handshake
following PMK derivation and then not updating the PMKID.
IEEE Std 802.11-2016 is somewhat vague in this area and it seems to
allow both cases to be used (initial PMKID or any consecutive PMKID
derived from the same PMK). While both cases could be supported that
would result in significantly more complex implementation and need to
store multiple PMKID values. It looks better to clarify the standard to
explicitly note that only the first PMKID derived after PMK derivation
is used (i.e., match the existing hostapd implementation).

Commit 3f53c006c7 ('nl80211: Ignore

wpa_supplicant ignore the next received disconnect event for cases where
wpa_supplicant itself requested a disconnection. This can result in
ignoring a disconnection notification in some cases.
Considering a P2P Client receiving disconnect event from the kernel
after a P2P group is started, drv->ignore_next_local_disconnect is
cleared to 0, then wpa_driver_nl80211_disconnect() will be called during
the removal of the group, in which drv->ignore_next_local_disconnect is
set to 1 by mistake.
Do not allow ignore_next_local_{disconnect,deauth} to be set to 1 if the
driver is not in associated state (drv->associated is 0) to avoid this

When removing an interface, hostapd_bss_deinit() frees all associated
STAs. If any of the stations is 40MHz intolerant, the cleanup invokes
ht40_intolerant_remove(), that in turn registers a 20->40MHz transition
timer for the last station (ap_ht2040_timeout() function). That timer is
never canceled; once it executes, the interface is gone, most likely
resulting in a segfault when referencing it.
While hostapd_interface_deinit() cancels the transition timer, it does
so before cleaning up STAs. Move the cancellation after STA cleanup to
cancel any timer that was registered during that operation.

A new SAE Commit message should not be allowed to drop an existing STA
entry since the sender of that Commit message cannot be authenticated
before receiving the Confirm message. This is important in particular
when PMF is used since this would provide a potential new path for
forcing a connection to be dropped.
Fix this by allowing a new SAE Authentication instance to be started
when the old instance is in Accepted state and the new Commit message
does not use the same peer-scalar value (checked in
sae_parse_commit_scalar()). When PMF is used, the AP will use SA Query
procedure when receiving the (Re)Association Request frame. In theory,
that step could be skipped in case of SAE Authentication since the
non-AP STA is demonstrating knowledge of the password. Anyway, there is
no allowance for that exception in the IEEE 802.11 standard, so at least
for now, leave this using SA Query procedure just like any other PMF
case.

When the channel time is zero the interference factor calculation falls
under divide by zero operation which results in invalid (NaN =
not-a-number) interference factor value. This leads to wrong ideal
channel selection in ACS during the scenario described below.
Scenario:
In VHT80 mode, the channel 36 (first channel) gets the channel time as
zero which causes the interfactor factor to be an invalid number (NaN).
Any operations (like addition, mulitplication, divide, etc.) with NaN
value results in a NaN value, so that average factor for the primary
channel 36 got the invalid value (NaN). Since channel 36 is the first
channel, ideal factor is assigned as NaN in the first iteration. The
following iteration condition check (factor < ideal_factor) with a NaN
value fail for all other primary channels. This results in channel 36
being chosen as the ideal channel in ACS which holds a NaN value.
Logs:

IEEE Std 802.11-2016, 12.7.1.7.1 indicates that the lifetime of the

the key was derived. This is currently stored in r0_key_lifetime, but
cache entries are not actually removed.
This commit uses the r0_key_lifetime configuration parameter when
wpa_auth_derive_ptk_ft() is called. This may need to be extended to use
the MSK lifetime, if provided by an external authentication server, with
some future changes. For PSK, there is no such lifetime, but it also
matters less as FT-PSK can be achieved without inter-AP communication.

that the given timeout for sanity, it may not exceed the locally configured

When wpa_supplicant is running on a Linux interface that is configured in

In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a

This commit reports the EAP method failure error code in a separate

The solution in this commit is generic to all EAP methods, and can be

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

To retain configurator information across hostapd/wpa_supplicant
restart, private key need to be maintained to generate a valid pair of
authentication keys (connector, netaccess_key, csign) for new enrollees
in the network.
Add a DPP_CONFIGURATOR_GET_KEY control interface API through which the
private key of an existing configurator can be fetched.
Command format:
DPP_CONFIGURATOR_GET_KEY <configurator_id>
The output from this command can then be used with
"DPP_CONFIGURATOR_ADD key=<hexdump>" to create the same key again.

The SAE AKM 00-0F-AC:8 is supposed to use EAPOL-Key Key Descriptor
Version 0 (AKM-defined) with AES-128-CMAC and NIST AES Key Wrap.
However, the previous implementation ended up using Key Descriptor
Version 2 (HMAC-SHA-1-128 and NIST AES Key Wrap). Fix this by using the
appropriate Key Descriptor Version and integrity algorithm. Use helper
functions to keep the selection clearer and more consistent between
wpa_supplicant and hostapd uses.
Note: This change is not backwards compatible. Both the AP and station
side implementations will need to be updated at the same time to
maintain functionality.

This extends dpp_test functionality to allow DPP exchanges to be stopped
after authentication is completed on the Initiator, i.e., after sending
out the Authentication Confirm message. Previously, dpp_test=89 was used
only on the Responder side to stop after receiving the Authentication
Confirm message. The main use case for this extended functionality is to
be able to stop the protocol exchange on a device that acts as
authentication Initiator and Enrollee.

When the number of live peers becomes 0 the KaY was setting
kay->authenticated true and telling the CP to connect AUTHENTICATED.
Per IEEE Std 802.1X-2010 Clause 12.2, MKA.authenticated means "the Key
Server has proved mutual authentication but has determined that
Controlled Port communication should proceed without the use of MACsec",
which means port traffic will be passed in the clear.
When the number of live peers becomes 0 the KaY must instead set
kay->authenticated false and tell the CP to connect PENDING. Per Clause
12.3 connect PENDING will "prevent connectivity by clearing the
controlledPortEnabled parameter."

Upon receipt of the "MACsec MKPDU SAK Use parameter set" the KaY verifies
that both the latest key and the old key are valid. If the local system
reboots or is reinitialized, the KaY won't have a copy of its old key.
Therefore if the KaY does not have a copy of its old key it should not
reject MKPDUs that contain old key data in the MACsec SAK Use parameter.

Commit e61fea6b46 ('SAE: Fix PMKSA caching
behavior in AP mode') modified the PSK fetching loop to not override PMK
in case of SAE with PMKSA caching. However, that commit missed the error
path cases where there is need to break from the loop with exact
negative of the check in the beginning of the loop. This could result in
hitting an infinite loop in hostapd if a station derived a different PMK
value from otherwise successfully completed SAE authentication or if a
STA used a different PMK with a PMKSA caching attempt after a previously
completed successful authentication.
Fix this by adding the matching break condition on SAE AKM within the
loops.

Now we can configure the network block so that it allows MFP setting for
the NL80211_CMD_CONNECT command. If the kernel finds an AP that requires
MFP, it'll be able to connect to it.
Note that since NL80211_MFP_OPTIONAL isn't supported for
NL80211_CMD_ASSOCIATE, we need to take the MFP configuration outside
nl80211_connect_common(). In addition, check that
NL80211_EXT_FEATURE_MFP_OPTIONAL is supported, to be backward compatible
with older kernels.

The current cfg80211 limit for the maximum NL80211_ATTR_PMK length is
48, so anything larger than that will result in the operation completely
failing. Since the PMKSA entries can be used without the PMK for most
purposes (the main use case for PMK currently is offloaded FILS
authentication), try to go ahead by configuring only the PMKID for the
case where 64-octet PMK is needed (which is currently limited to only
DPP with NIST P-521 and brainpoolP512r1 curves). This can fix DPP
connections with drivers that expect to get the PMKID through this
interface while still leaving the actual 4-way handshake for user space.
