a03406dbe2 DPP: Move Authentication Response building into a separate function
This cleans up old dpp_auth_build_resp() (now dpp_auth_build_resp_ok())
a bit by separating initialization steps for a DPP authentication
session from the code needed to build the frame. This allows
dpp_auth_build_resp_status() to share the helper function instead of
having to maintain a duplicated message construction implementation. In
addition, this makes it easier to remove some of the attributes for
protocol testing purposes.

a0bf1b68c0 Remove all PeerKey functionality
This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.

This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.

Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

53bb18cc8b Prevent installation of an all-zero TK
Properly track whether a PTK has already been installed to the driver
and the TK part cleared from memory. This prevents an attacker from
trying to trick the client into installing an all-zero TK.

This fixes the earlier fix in commit
ad00d64e7d ('Fix TK configuration to the
driver in EAPOL-Key 3/4 retry case') which did not take into account
possibility of an extra message 1/4 showing up between retries of
message 3/4.

4cada9dcc1 FILS: Add DHss into FILS-Key-Data derivation when using FILS SK+PFS
This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss
here means there would not be proper PFS for the case where PMKSA
caching is used with FILS SK+PFS authentication. This was not really the
intent of the FILS design and that issue was fixed during REVmd work
with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that add DHss into FILS-Key-Data (and PTK, in practice) derivation for
the PMKSA caching case so that a unique ICK, KEK, and TK are derived
even when using the same PMK.

Note: This is not backwards compatible, i.e., this breaks PMKSA caching
with FILS SK+PFS if only STA or AP side implementation is updated.

41b8191485 FILS: Update PMKID derivation rules for ERP key hierarchy establishment
IEEE Std 802.11ai-2016 had missed a change in the Pairwise key hierarchy
clause (12.7.1.3 in IEEE Std 802.11-2016) and due to that, the previous
implementation ended up using HMAC-SHA-1 -based PMKID derivation. This
was not really the intent of the FILS design and that issue was fixed
during REVmd work with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that change FILS cases to use HMAC-SHA-256 and HMAC-SHA-384 based on the
negotiated AKM.

Update the implementation to match the new design. This changes the
rsn_pmkid() function to take in the more generic AKMP identifier instead
of a boolean identifying whether SHA256 is used.

Note: This is not backwards compatible, i.e., this breaks PMKSA caching
based on the initial ERP key hierarchy setup if only STA or AP side
implementation is updated. PMKSA caching based on FILS authentication
exchange is not impacted by this, though.

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.

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.

6d014ffc6e Make struct wpa_eapol_key easier to use with variable length MIC
Suite B 192-bit addition from IEEE Std 802.11ac-2013 replaced the
previous fixed length Key MIC field with a variable length field. That
change was addressed with an addition of a new struct defined for the
second MIC length. This is not really scalable and with FILS coming up
with a zero-length MIC case for AEAD, a more thorough change to support
variable length MIC is needed.

Remove the Key MIC and Key Data Length fields from the struct
wpa_eapol_key and find their location based on the MIC length
information (which is determined by the AKMP). This change allows the
separate struct wpa_eapol_key_192 to be removed since struct
wpa_eapol_key will now include only the fixed length fields that are
shared with all EAPOL-Key cases in IEEE Std 802.11.

96590564d6 FT: Allow PMK-R0 and PMK-R1 for FT-PSK to be generated locally
Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.

This patch introduces the generation of the required PMKs locally for
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.

So for FT-PSK networks, no configuration of inter-AP communication is
needed anymore when using ft_psk_generate_local=1 configuration. The
default behavior (ft_psk_generate_local=0) remains to use the pull/push
protocol.

fcd85d9a3f Add QCA vendor commands/attributes for indoor location
Assign QCA vendor specific commands, attributes, and events for
supporting indoor location features.

These features include:

1. Fine timing measurement (FTM) - allows measurement of distance
between two stations. Based on IEEE P802.11-REVmc/D7.0, 11.24.6 FTM is
performed between two stations: one is an initiator, typically a client
that wants to measure distance to another AP, and one is a responder,
typically an AP which responds to measurement requests from other
clients. The responder can be configured to report its location, either
in absolute coordinates (LCI) or free-form description (LCR).

2. Angle of arrival (AOA) - allows measurement of azimuth and elevation
between two stations.

The above features can be combined to allow a station to get an accurate
indoor location.

6c33eed3ee mesh: Fix PMKID to match the standard
IEEE Std 802.11-2012 11.3.5.4 specifies the PMKID for SAE-derived keys
as:

   L((commit-scalar + peer-commit-scalar) mod r, 0, 128)

This is already calculated in the SAE code when the PMK is derived, but
not saved anywhere. Later, when generating the PMKID for plink action
frames, the definition for PMKID from 11.6.1.3 is incorrectly used.
Correct this by saving the PMKID when the key is generated and use it
subsequently.

3c108b7573 EAP peer: External server certificate chain validation
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.

f32227ed9e Add QCA vendor attribute and event to indicate subnet change status
This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.

The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)

717333f4e4 FST: Add the Fast Session Transfer (FST) module
Fast Session Transfer (FST) is the transfer of a session from a channel
to another channel in a different frequency band. The term "session"
refers to non-physical layer state information kept by a pair of
stations (STAs) that communicate directly (i.e., excludes forwarding).

The FST is implemented in accordance with IEEE Std 802.11ad-2012.

Definitions

 * FST interface - an interface for which FST functionality is enabled
 * FST group - a bunch of FST interfaces representing single
		multi-band STA
 * FST peer - a multi-band capable STA connected
 * FST module - multi-band operation functionality implemented in
		accordance with IEEE Std 802.11ad-2012 (see 10.32
		Multi-band operation) as a part of hostapd/wpa_supplicant
 * FST manager - an external application that implements custom FST
		related logic, using the FST module's interfaces
		accessible via CLI or D-Bus

This commit introduces only the FST module. Integration of the FST
module into the hostapd/wpa_supplicant and corresponding CLI/D-Bus
interfaces and FST related tests are covered in separate commits.

FST manager application is out of scope of these commits.

As FST aggregates a few interfaces into FST group, the FST module uses
global CLI for both commands and notifications. It also exposes
alternative non-interface based D-Bus subtree for this purposes.

Configuration and Initialization

 * FST functionality can enabled by compilation flag (CONFIG_FST)
 * hostapd/wpa_supplicant controlling multiple interfaces are used for
   FST
 * once enabled by compilation, the FST can be enabled for specific
   interfaces in the configuration files
 * FST interfaces are aggregated in FST groups (fst_group_id config file
   entry), where each FST group:
   - represents one multi-band device
   - should have two or more FST interfaces in it
 * priority (fst_priority config file entry) must be configured for each
   FST interface. FST interface with higher priority is the interface FST
   will always try to switch to. Thus, for example, for the maximal
   throughput, it should be the fastest FST interface in the FST setup.
 * default Link Loss Timeout (LLT) value can be configured for each FST
   interface (fst_llt config file entry). It represents LLT to be used
   by FST when this interface is active.
 * FST interfaces advertise the Multi-band capability by including the
   Multi-band element in the corresponding frames

FST CLI commands:

 * fst list_groups - list FST groups configured.
 * fst list_ifaces - list FST interfaces which belong to specific group
 * fst iface_peers - list Multi-Band STAs connected to specific interface
 * fst list_sessions - list existing FST sessions
 * fst session_get - get FST session info
 * fst session_add - create FST session object
 * fst session_set - set FST session parameters (old_iface, new_iface,
                     peer_addr, llt)
 * fst session_initiate - initiate FST setup
 * fst session_respond - respond to FST setup establishemnt attempt by
                         counterpart
 * fst session_transfer - initiate FST switch
 * fst session_teardown - tear down FST Setup but leave the session object
			  for reuse
 * fst session_remove - remove FST session object

FST CLI notifications:
  * FST-EVENT-PEER - peer state changed (CONNECT/DISCONNECT)
  * FST-EVENT-SESSION - FST session level notification with following
                        sub-events:
     - EVENT_FST_SESSION_STATE - FST session state changed
     - EVENT_FST_ESTABLISHED - previously initiated FST session became
                               established
     - EVENT_FST_SETUP - new FST session object created due to FST session
                         negotiation attempt by counterpart

All the FST CLI commands and notifications are also implemented on D-Bus
for wpa_supplicant.

IEEE 802.11 standard compliance

FST module implements FST setup statemachine in compliance with IEEE
802.11ad (P802.11-REVmc/D3.3), as it described in 10.32 Multi-band
operation (see also Figure 10-34 - States of the FST setup protocol).

Thus, for example, the FST module initiates FST switch automatically
when FST setup becomes established with LLT=0 in accordance with
10.32.2.2 Transitioning between states.

At the moment, FST module only supports non-transparent STA-based FST
(see 10.32.1 General).

The FT-specific check for valid group cipher in wpa_ft_gen_req_ies() was
not up-to-date with the current list of supported ciphers. Fix this by
using a generic function to determine validity of the cipher. In
practice, this adds support for using CCMP-256 and GCMP-256 as the group

This is not much of an issue for the locally generated commit-scalar

potentially force the exchange to expose key material without this

d447cd596f Updates for stricter automatic memcpy bounds checking
Both Android's libc and glibc support _FORTIFY_SOURCE, a compiler
and libc feature which inserts automatic bounds checking into
common C functions such as memcpy() and strcpy(). If a buffer
overflow occurs when calling a hardened libc function, the
automatic bounds checking will safely shutdown the program and
prevent memory corruption.

Android is experimenting with _FORTIFY_SOURCE=3, a new fortify
level which enhances memcpy() to prevent overflowing an element
of a struct. Under the enhancements, code such as

  struct foo {
    char empty[0];
    char one[1];
    char a[10];
    char b[10];
  };

  int main() {
    foo myfoo;
    int n = atoi("11");
    memcpy(myfoo.a, "01234567890123456789", n);
    return 0;
  }

will cleanly crash when the memcpy() call is made.

Fixup hostap code to support the new level. Specifically:

* Fixup sha1_transform so it works with the enhanced bounds checking.
The old memcpy() code was attempting to write to context.h0, but that
structure element is too small and the write was extending (by design)
into h1, h2, h3, and h4. Use explicit assignments instead of
overflowing the struct element.

* Modify most of the structures in ieee802_11_defs.h to use ISO C99
flexible array members (https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html)
instead of a zero length array. Zero length arrays have zero length,
and any attempt to call memcpy() on such elements will always overflow.
Flexible array members have no such limitation. The only element not
adjusted is probe_req, since doing so will generate a compile time error,
and it's not obvious to me how to fix it.

interface (ctrl_iface or D-Bus) similarly to the EAP network parameter

that prevents it from getting stored to the configuration file.

For example:

Event:

Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"

38cb0a2db6 AP: Drop retransmitted auth/assoc/action frames
It is possible that a station device might miss an ACK for an
authentication, association, or action frame, and thus retransmit the
same frame although the frame is already being processed in the stack.
While the duplicated frame should really be dropped in the kernel or
firmware code where duplicate detection is implemented for data frames,
it is possible that pre-association cases are not fully addressed (which
is the case at least with mac80211 today) and the frame may be delivered
to upper layer stack.

In such a case, the local AP will process the retransmitted frame although
it has already handled the request, which might cause the station to get
confused and as a result disconnect from the AP, blacklist it, etc.

To avoid such a case, save the sequence control of the last processed
management frame and in case of retransmissions drop them.
