adf0478e8e AP: Store STA supported operating classes information
This makes hostapd track Supported Operating Classes information from
the associated STAs. The stored information is available through the STA
control interface command (supp_op_classes row) as a hexdump of the
Supported Operating Classes element starting from the Length field. This
information can be used as input to BSS transition management and
channel switching decisions.

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.

59e78c2408 FT: Fix FTIE generation for 4-way handshake after FT protocol run
wpa_insert_pmkid() did not support cases where the original RSN IE
included any PMKIDs. That case can happen when PTK rekeying through
4-way handshake is used after FT protocol run. Such a 4-way handshake
used to fail with wpa_supplicant being unable to build the EAPOL-Key msg
2/4.

Fix this by extending wpa_insert_pmkid() to support removal of the old
PMKIDs, if needed.

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)

207976f053 Fix Suite B 192-bit AKM to use proper PMK length
In addition to the PTK length increasing, the length of the PMK was
increased (from 256 to 384 bits) for the 00-0f-ac:12 AKM. This part was
missing from the initial implementation and a fixed length (256-bit) PMK
was used for all AKMs.

Fix this by adding more complete support for variable length PMK and use
384 bits from MSK instead of 256 bits when using this AKM. This is not
backwards compatible with the earlier implementations.

0e2412d086 Add option to reject authentication on 2.4 GHz from dualband STA
The new no_auth_if_seen_on=<ifname> parameter can now be used to

on another radio.

This can be used with enabled track_sta_max_num configuration on another
interface controlled by the same hostapd process to reject
authentication attempts from a station that has been detected to be
capable of operating on another band, e.g., to try to reduce likelihood
of the station selecting a 2.4 GHz BSS when the AP operates both a 2.4
GHz and 5 GHz BSS concurrently.

Note: Enabling this can cause connectivity issues and increase latency for

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

0c2b3f6541 SAE: Reject commit-scalar value 1
IEEE Std 802.11-2012 description of SAE does not require this, i.e., it
describes the requirement as 0 < scalar < r for processing the Commit
message. However, this is not correct and will be changes to 1 < scalar
< r to match the Dragonfly description so that a trivial secret case
will be avoided explicitly.

This is not much of an issue for the locally generated commit-scalar
since it would be very unlikely to get the value of 1. For Commit
message processing, a peer with knowledge of the password could
potentially force the exchange to expose key material without this
check.

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.

a52410c29f Allow PSK/passphrase to be set only when needed
The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.

For example:

Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk

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

Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.

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.

been derived, but wpa_supplicant functionality needs to be moved from
processing of EAPOL-Key frame 1/4 to 3/4 to have the KCK available.

86bd36f0d5 Add generic mechanism for adding vendor elements into frames
This adds following new control interface commands to allow arbitrary
vendor elements to be added into number of frames:

VENDOR_ELEM_ADD <frame id> <hexdump of elem(s)>
VENDOR_ELEM_GET <frame id>
VENDOR_ELEM_REMOVE <frame id> <hexdump of elem(s)>
VENDOR_ELEM_REMOVE <frame id> *

The following frames are supported in this commit (additional frames can
be added in the future):

0 = Probe Request frame in P2P device discovery
1 = Probe Response frame from P2P Device role
2 = Probe Response frame from P2P GO
3 = Beacon frame from P2P GO
4 = PD Req
5 = PD Resp
6 = GO Neg Req
7 = GO Neg Resp
8 = GO Neg Conf
9 = Invitation Request
10 = Invitation Response
11 = P2P Association Request
12 = P2P Association Response

One or more vendor element can be added/removed with the commands. The
hexdump of the element(s) needs to contain the full element (id, len,
payload) and the buffer needs to pass IE parsing requirements to be
accepted.
