624b8a061f utils: Add ssid_parse() function
Add a function that parses SSID in text or hex format. In case of the
text format, the SSID is enclosed in double quotes. In case of the hex
format, the SSID must include only hex digits and not be enclosed in
double quotes. The input string may include other arguments after the
SSID.

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

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)

was used for all AKMs.

Fix this by adding more complete support for variable length PMK and use

The new no_auth_if_seen_on=<ifname> parameter can now be used to
configure hostapd to reject authentication from a station that was seen
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
connecting with the AP.

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).

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

potentially force the exchange to expose key material without this

this length was supposed to validated by the users of the element
parser, there are not really any valid cases where the maximum length of
32 octet SSID would be exceeded and as such, the parser itself can
enforce the limit as an additional protection.

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.

In case the AP we are associating with advertises support for RRM,
advertise our own RRM support in the (Re)Association Request frame. This
is done by adding an RRM Capabilities IE. The underlying driver is
expected to further add a Power Capabilities IE to the request, and set
the Radio Measurement flag in the Capability Info field. At this point
the RRM Capabilities IE advertises no measurement support.

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.

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

905828fea4 hostapd: Fix vht_capab 'Maximum A-MPDU Length Exponent' handling
As per IEEE Std 802.11ac-2013, 'Maximum A-MPDU Length Exponent' field
value is in the range of 0 to 7. Previous implementation assumed EXP0 to
be the maximum length (bits 23, 24 and 25 set) what is incorrect.

This patch adds options to set it up within the 0 to 7 range.

(link local, which is based on the MAC address). Also add scope id
support for link local case.

25ef8529c1 P2P: Add support for IP address assignment in 4-way handshake
This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.

The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:

ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100

DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.

If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed

5bf9a6c859 P2P: Add event messages for possible PSK failures on P2P groups
It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.

Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).

In addition to indicating the error cases for persistent groups, all
this type of PSK failures end up in the client removing the group with
the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

bb0122f3e8 SAE: Add forgotten commit element validation step for FFC groups
The peer commit element needs to be validated to pass one of the steps
listed in IEEE 802.11, 11.3.5.4:
scalar-op(r, ELEMENT) = 1 modulo p

Similar step was present for ECC groups, but was missing for FFC groups.
This is needed to avoid dictionary attacks.

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

b1f122964e Add generic GAS request mechanism
The new gas_request and gas_response_get commands can be used to request
arbitary GAS queries to be performed. These can be used with ANQP or
with other (including vendor specific) advertisement protocols.

gas_request <BSSID> <AdvProtoID> [Query]
gas_response_get <addr> <dialog token> [offset,length]

For example, ANQP query for Capability list in interactive wpa_cli
session:

> gas_request 02:00:00:00:01:00 00 000102000101
<3>GAS-RESPONSE-INFO addr=02:00:00:00:01:00 dialog_token=0
status_code=0 resp_len=32
> gas_response_get 02:00:00:00:01:00 00
01011c00010102010501070108010c01dddd0c00506f9a110200020304050607
> gas_response_get 02:00:00:00:01:00 00 0,10

> gas_response_get 02:00:00:00:01:00 00 20,10
506f9a11020002030405
> gas_response_get 02:00:00:00:01:00 00 30,2
0607

It should be noted that the maximum length of the response buffer is
currently 4096 bytes which allows about 2000 bytes of the response data
to be fetched with a single gas_response_get command. If the response is
longer, it can be fetched in pieces as shown in the example above.

whether the AP allows WEP to be used as a group cipher. If so, allow
the AP to be selected if we are configured to use static WEP or
IEEE 802.1X (non-WPA).

It should be noted that this is still somewhat more restricted in AP
selection than earlier wpa_supplicant branches (0.7.x or older) that
ignore the WPA/RSN IE completely when configured for non-WPA.

failure to slow down brute force attacks against the AP PIN.

This avoids problems with some external Registrars that may try
to use the same PIN multiple times without user input. Now, the
user will still be able to fix the PIN and try again later while
a real attack is delayed enough to make it impractical.

26e23750b9 FT: Fix FT 4-Way Handshake to include PMKR1Name in messages 2 and 3
IEEE Std 802.11r-2008, 11A.4.2 describes FT initial mobility domain
association in an RSN to include PMKR1Name in the PMKID-List field
in RSN IE in messages 2/4 and 3/4. This makes the RSN IE not be
bitwise identical with the values used in Beacon, Probe Response,
(Re)association Request frames.

The previous versions of wpa_supplicant and hostapd did not add the
PMKR1Name value in EAPOL-Key frame and did not accept it if added
(due to bitwise comparison of RSN IEs). This commit fixes the
implementation to be compliant with the standard by adding the
PMKR1Name value into EAPOL-Key messages during FT 4-Way Handshake and
by verifying that the received value matches with the value derived
locally.

This breaks interoperability with previous wpa_supplicant/hostapd
versions.

00468b4650 Add TLS client events, server probing, and srv cert matching
This allows external programs (e.g., UI) to get more information
about server certificate chain used during TLS handshake. This can
be used both to automatically probe the authentication server to
figure out most likely network configuration and to get information
about reasons for failed authentications.

The follow new control interface events are used for this:
CTRL-EVENT-EAP-PEER-CERT
CTRL-EVENT-EAP-TLS-CERT-ERROR

In addition, there is now an option for matching the server certificate
instead of the full certificate chain for cases where a trusted CA is
not configured or even known. This can be used, e.g., by first probing
the network and learning the server certificate hash based on the new
events and then adding a network configuration with the server
certificate hash after user have accepted it. Future connections will
then be allowed as long as the same server certificate is used.

Authentication server probing can be done, e.g., with following
configuration options:
    eap=TTLS PEAP TLS
    identity=""
    ca_cert="probe://"

Example set of control events for this:
CTRL-EVENT-EAP-STARTED EAP authentication started
CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21
CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected
CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' hash=5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a
CTRL-EVENT-EAP-TLS-CERT-ERROR reason=8 depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' err='Server certificate chain probe'
CTRL-EVENT-EAP-FAILURE EAP authentication failed

Server certificate matching is configured with ca_cert, e.g.:
    ca_cert="hash://server/sha256/5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"

TLS libraries (including internal implementation) may be added in
the future.

EADDRINUSE, there is an existing socket file with the name we are trying
to create. Since getpid() is unique, there cannot be another process
using that socket and we can just unlink the file and try again. This
can speed up client connection if wpa_cli is killed without allowing it
to clean up the socket file. [Bug 288]

3b2cf800af WPS: Lock AP Setup on multiple AP PIN validation failures
If a Registrar tries to configure the AP, but fails to validate the
device password (AP PIN), lock the AP setup after four failures. This
protects the AP PIN against brute force guessing attacks.

a609915233 Allow WPS APs for PIN enrollment even without Selected Registrar
Some WPS APs do not set Selected Registrar attribute to 1 properly when
using an external Registrar. Allow such an AP to be selected for PIN
registration after couple of scan runs that do not find APs marked with
Selected Registrar = 1. This allows wpa_supplicant to iterate through
all APs that advertise WPS support without delaying connection with
implementations that set Selected Registrar = 1 properly.

aabe26a136 WPS: Added option to disable AP auto-config on first registration
This operation can now be moved into an external program by configuring
hostapd with wps_cred_processing=1 and skip_cred_build=1. A new
ctrl_iface message (WPS-REG-SUCCESS <Enrollee MAC addr> <UUID-E>) will
be used to notify external programs of each successful registration and
that can be used as a tricker to move from unconfigured to configured
state.

adddffd129 Fixed MFP Association Comeback mechanism to use Timeout Interval IE
The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.

ad08c3633c Added preliminary Wi-Fi Protected Setup (WPS) implementation
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.

Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.

4fba48a5a7 Silence compiler warnings about out of array bounds indexes
struct wpa_ie_hdr had separate fields for 24-bit OUI and 8-bit oui_type
for WPA/RSN selectors. {WPA,RSN}_SELECTOR_{GET,PUT} access these four
octets through oui and the "out-of-bounds" access for the fourth octet is
actually reading/writing oui_type. This works fine, but some tools complain
about the array bounds "failure". Since oui_type is never accessed
separately, the simplest fix is to just combine these into a single 4-octet
field.
