9b7a1bd7ed Option to reduce Probe Response frame responses during max STA
The new hostapd configuration parameter no_probe_resp_if_max_sta=1 can
be used to request hostapd not to reply to broadcast Probe Request
frames from unassociated STA if there is no room for additional stations
(max_num_sta). This can be used to discourage a STA from trying to
associate with this AP if the association would be rejected due to
maximum STA limit.

ca33a5e895 Add "git describe" based version string postfix
If hostapd or wpa_supplicant is built from a git repository, add a
VERSION_STR postfix from the current git branch state. This is from "git
describe --dirty=+". VERSION_STR will thus look something like
"2.6-devel-hostap_2_5-132-g4363c0d+" for development builds from a
modified repository.

This behavior is enabled automatically if a build within git repository
is detected (based on ../.git existing). This can be disabled with
CONFIG_NO_GITVER=y in wpa_supplicant/.config and hostapd/.config.

2b12b3602a P2P: Do not reply to GO Negotiation Request if peer is waiting for us
This improves robustness of GO Negotiation in special cases where GO
Negotiation Request frames from the peer may end up getting delivered
multiple times, e.g., due to interference and retransmitted frames not
getting properly filtered out in duplicate detection (which is something
that number of drivers do not implement for pre-associated state).

If we have already replied with GO Negotiation Response frame with
Status 1 (not yet ready), do not reply to another GO Negotiation Request
frame from the peer if we have already received authorization from the
user (P2P_CONNECT command) for group formation and have sent out our GO
Negotiation Request frame. This avoids a possible sequence where two
independent GO Negotiation instances could go through in parallel if the
MAC address based rule on avoiding duplicate negotiations is not able to
prevent the case. This can allow GO Negotiation to complete successfully
whereas the previous behavior would have likely resulted in a failure
with neither device sending a GO Negotiation Confirm frame.

e8dc205f17 nl80211: Disable 11b rates for P2P (additional cases)
Some drivers (like mac80211) do not accept changing the TX bitrate mask
before the network interface is up. Thus, calling
nl80211_disable_11b_rates() before the interface is up fails, and the
P2P network interface continues to use invalid bitrates.

To fix this call nl80211_disable_11b_rates() immediately after the
interface is brought up (and also after rfkill is unblocked).

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.

ae7d9fbd3d Remove unreachable PMKSA cache entry addition on Access-Accept
The previous implementation used an obsolete sm->eapol_key_crypt pointer
which was not set anywhere (i.e., was always NULL). In addition, the
condition of sm->eap_if->eapKeyAvailable was not valid here since this
is the case of MSK from an external authentication server and not the
internal EAP server. Consequently, the wpa_auth_pmksa_add() call here
was never used.

The PMKSA cache was still added, but it happened at the completion of
the 4-way handshake rather than at the completion of EAP authentication.
That later location looks better, so delete the unreachable code in
Access-Accept handling. In addition, remove the now complete unused
struct eapol_state_machine eapol_key_* variables.

ebd32943cb P2PS: Add channel policy to PD Request
Add operating channel selection and channel list processing similar to
that done when building GO Negotiation Request, i.e., consider the
currently used channels, configured channels, etc.

P2PS introduces a flow where a responder needs to provide channel data
without being previously aware of the current constraints, i.e., the
channels currently in use by other interfaces. To handle this, extend
the get_group_capability() callback to also handle channel selection
aspects of group capabilities.

In case there is an active P2P GO that is going to be used for the P2PS
PD, force its current operating frequency in the PD attributes.

bdee6ca0e0 BoringSSL: Implement support for OCSP stapling
BoringSSL has removed the OpenSSL OCSP implementation (OCSP_*()
functions) and instead, provides only a minimal mechanism for include
the status request extension and fetching the response from the server.
As such, the previous OpenSSL-based implementation for OCSP stapling is
not usable with BoringSSL.

Add a new implementation that uses BoringSSL to request and fetch the
OCSP stapling response and then parse and validate this with the new
implementation within wpa_supplicant. While this may not have identical
behavior with the OpenSSL-based implementation, this should be a good
starting point for being able to use OCSP stapling with BoringSSL.

f94e4c20e4 P2PS: Send follow-on PD response only if status is 12

   different than 12 (seeker side).
2. Don't wait for the follow-on PD Response if the follow-on PD
   Request was sent with the status different than 12 (advertiser

3. If the follow-on PD Request was sent with the status different
   than 12 use the follow-on PD Request ACK as PD completion event

segment 0 at 5775. This segment is only indicated indirectly in the hw
mode list by the HOSTAPD_CHAN_VHT_50_30 flag. The hw mode list doesn't
have any elements with frequency 5775 to allow the conversion to a
channel number. Thus, we need to use ieee80211_freq_to_chan() instead.

doesn't reflect correctly the sub-band spectrum breakdown and can't be
effectively used by clients, publish only the minimal required part
which is the current operating class.

When the operating class is provided for channel switch, the AP/P2P GO

ad00d64e7d Fix TK configuration to the driver in EAPOL-Key 3/4 retry case
Commit 7d711541dc ('Clear TK part of PTK
after driver key configuration') started clearing TK from memory
immediately after having configured it to the driver when processing
EAPOL-Key message 3/4. While this covered the most common case, it did
not take into account the possibility of the authenticator having to
retry EAPOL-Key message 3/4 in case the first EAPOL-Key message 4/4
response is lost. That case ended up trying to reinstall the same TK to
the driver, but the key was not available anymore.

Fix the EAPOL-Key message 3/4 retry case by configuring TK to the driver
only once. There was no need to try to set the same key after each
EAPOL-Key message 3/4 since TK could not change. If actual PTK rekeying
is used, the new TK will be configured once when processing the new
EAPOL-Key message 3/4 for the first time.

24fd20438f WPS: Fix num_probereq_cb clearing on DISABLE to avoid segfault
Reset hapd->num_probereq_cb to 0 on an interface deinit to avoid
unexpected behavior if the same interface is enabled again without fully
freeing the data structures. hostapd_register_probereq_cb() increments
hapd->num_probereq_cb by one and leaves all old values unchanged. In
this deinit+init case, that would result in the first entry in the list
having an uninitialized pointer and the next Probe Request frame
processing would likely cause the process to terminate on segmentation
fault.

This issue could be hit when hostapd was used with WPS enabled (non-zero
wps_state configuration parameter) and control interface command DISABLE
and ENABLE were used.

disconnection event without advancing to the AUTHENTICATING state to
clear keyRun before the IEEE 802.11 RSN authenticator state machine runs
and that may advance from AUTHENTICATION2 to INITPMK if keyRun = TRUE
has been left from the last association. This can be avoided by clearing
keyRun here.

It was possible to hit this corner case in the hwsim test case

station getting disconnected when entering INITPMK without going through

Config file is written to a temp file and then it is renamed to the
original config file. However, it is possible that the rename operation
will be commited to storage while file data will be still in cache
causing original config file to be empty or partially written in case of
a system reboot without a clean shutdown. Make this less likely to occur
by forcing the data to be written to the storage device before renaming
the file.

2ce741fe0f WPS: Fix HTTP body length check
Commit 7da4f4b499 ('WPS: Check maximum
HTTP body length earlier in the process') added too strict check for
body length allocation. The comparison of new_alloc_nbytes against
h->max_bytes did not take into account that HTTPREAD_BODYBUF_DELTA was
added to previous allocation even if that ended up going beyond
h->max_bytes. This ended up rejecting some valid HTTP operations, e.g.,
when checking AP response to WPS ER setting selected registrar.

Fix this by taking HTTPREAD_BODYBUF_DELTA into account.

BoringSSL commit 533ef7304d9b48aad38805f1997031a0a034d7fe ('Remove
SSL_clear calls in handshake functions.') triggered a regression for
EAP-TLS/TTLS/PEAP session resumption in wpa_supplicant due to the
removed SSL_clear() call in ssl3_connect() going away and wpa_supplicant
not calling SSL_clear() after SSL_shutdown(). Fix this by adding the
SSL_clear() call into wpa_supplicant after SSL_shutdown() when preparing
the ssl instance for another connection.

be safe to add this call to wpa_supplicant unconditionally.

44fa5e747b FT: Remove optional fields from RSNE when using PMF
The PMKIDCount, PMKID List, and Group Management Cipher Suite fields are
optional to include in the RSNE in cases where these would not have
values that are different from the default values. In practice,
PMKIDCount is always 0 in Beacon and Probe Response frames, so the only
field of these that could have a non-default value is Group Management
Cipher Suite. When BIP is used, that field is not needed either due to
BIP being the default cipher when PMF is enabled.

Remove these fields from RSNE when BIP is used to save six octets in
Beacon and Probe Response frames. In addition to reduced frame length,
this is a workaround for interoperability issues with iOS 8.4 in cases
where FT and PMF are enabled. iOS seems to be rejecting EAPOL-Key msg
3/4 during FT initial mobility domain association if the RSNE includes
the PMKIDCount field.

ecd40fef74 mesh: Fix mesh SAE auth on low spec devices
The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.

After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).

On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().

So this patch makes the default to 1000(msec) and makes it configurable.

This issue does not occur on infrastructure SAE because the
dot11RSNASAERetransPeriod is not used on it.

That is not really valid since this code path can be reached only if
found != 0 and in such a case, oper_freq is set. Anyway, it seems better
to avoid compiler warnings, so add an unnecessary initialization for
oper_freq for now.

MD5 is not allowed in such builds, so comment out md5_vector() from the

276a3c44dd OpenSSL: Implement aes_wrap/aes_unwrap through EVP for CONFIG_FIPS=y
The OpenSSL internal AES_wrap_key() and AES_unwrap_key() functions are
unfortunately not available in FIPS mode. Trying to use them results in
"aes_misc.c(83): OpenSSL internal error, assertion failed: Low level API
call to cipher AES forbidden in FIPS mode!" and process termination.
Work around this by reverting commit
f19c907822 ('OpenSSL: Implement aes_wrap()
and aes_unwrap()') changes for CONFIG_FIPS=y case. In practice, this
ends up using the internal AES key wrap/unwrap implementation through
the OpenSSL EVP API which is available in FIPS mode. When CONFIG_FIPS=y
is not used, the OpenSSL AES_wrap_key()/AES_unwrap_key() API continues
to be used to minimize code size.

6cc364946c P2P: Process preferred frequency list as part of GO Neg Req/Resp
When processing a GO Negotiation Request and Response, if local driver
supports the preferred channel list extension, then:

- Check if peer's preference for operating channel is already included
  in our preferred channel list and if so, take the oper_channel as is.

- If peer's preference for operating channel is not in local device's
  preferred channel list and peer device has provided its preferred
  frequency list in the GO Negotiation Request/Response, then find a
  channel that is common for both preferred channel lists and use it
  for oper_channel.

- If peer's preference for operating channel is not in local device's
  preferred channel list and peer device doesn't use preferred channel
  list extension, i.e., no preferred channel list in GO Negotiation
  Request/Response, then look for a channel that is common for local
  device's preferred channel list and peer's list of supported channels
  and use it for oper_channel.

- In case no common channel is found, use the peer's preference for
  oper_channel as is.

7c524a64c1 eloop: Fix cases where a socket is reopened from a timeout/signal handler
It was possible for a registered eloop socket handler to be unregistered
and re-registered for a re-opened socket with the same fd from a timeout
or signal handler. If such a case happened with the old socket having a
pending event waiting for processing, some eloop combinations could end
up calling the new handler function with the new socket and get stuck
waiting for an event that has not yet happened on the new socket. This
happened with timeout and signal handlers with all eloop.c types. In
addition to that, the epoll case could also trigger this when a socket
handler re-registered a re-opened socket.

Fix these by checking whether there has been socket handler changes
during processing and break the processing round by going back to
select/poll/epoll for an updated result if any changes are done during
the eloop handler calls before processing the old socket results.

be terminated forcefully even though there would have been possibility

Terminate the loop if pending signal handling requests termination.

In addition, make eloop_terminated() return 1 on eloop.pending_terminate

shortly and there is no point in starting additional processing.

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).

bddc51e8e4 RSN: Stop connection attempt on apparent PMK mismatch
If WPA2-Enterprise connection with full EAP authentication (i.e., no
PMKSA caching used) results in a PMKID that does not match the one the
AP/Authenticator indicates in EAPOL-Key msg 1/4, there is not much point
in trying to trigger full EAP authentication by sending EAPOL-Start
since this sequence was immediately after such full authentication
attempt.

There are known examples of authentication servers with incorrect MSK
derivation when TLS v1.2 is used (e.g., FreeRADIUS 2.2.6 or 3.0.7 when
built with OpenSSL 1.0.2). Write a clear debug log entry and also send
it to control interface monitors when it looks likely that this case has
been hit. After doing that, stop the connection attempt by
disassociating instead of trying to send out EAPOL-Start to trigger new
EAP authentication round (such another try can be tried with a new
association).

df9079e727 NFC: Fix payload length validation in NDEF record parser
It was possible for the 32-bit record->total_length value to end up
wrapping around due to integer overflow if the longer form of payload
length field is used and record->payload_length gets a value close to
2^32. This could result in ndef_parse_record() accepting a too large
payload length value and the record type filter reading up to about 20
bytes beyond the end of the buffer and potentially killing the process.
This could also result in an attempt to allocate close to 2^32 bytes of
heap memory and if that were to succeed, a buffer read overflow of the
same length which would most likely result in the process termination.
In case of record->total_length ending up getting the value 0, there
would be no buffer read overflow, but record parsing would result in an
infinite loop in ndef_parse_records().

Any of these error cases could potentially be used for denial of service
attacks over NFC by using a malformed NDEF record on an NFC Tag or
sending them during NFC connection handover if the application providing
the NDEF message to hostapd/wpa_supplicant did no validation of the
received records. While such validation is likely done in the NFC stack
that needs to parse the NFC messages before further processing,
hostapd/wpa_supplicant better be prepared for any data being included
here.

Fix this by validating record->payload_length value in a way that
detects integer overflow. (CID 122668)

one peer becomes a P2P GO and the P2P Client joins it. Since multiple

5cc6ec0f68 P2PS: Set intended interface address correctly for new group
If a device may be an explicit GO, it adds the GO details in the PD
Request. First, we try to reuse an active GO. If it is not present, we
try to reuse a non-active persistent group. In the latter case, if a
dedicated P2P interface is needed, the intended address should be that
of the pending interface. However, the wpas_get_go_info() provided the
ssid->bssid address, which is the address of the P2P device. This might
result in an incorrect intended interface attribute in the PD Request in
case a separate group interface is used.

Fix this by setting group_iface variable to true only if a dedicated
interface should be used and set the attribute accordingly.

ea210b9f8a P2P: Refactor p2p_process_prov_disc_resp() function
Add 'else if' to P2PS status verification to prevent a redundant
condition checking. The first 'if' condition is true only if
  status == P2P_SC_SUCCESS || status == P2P_SC_SUCCESS_DEFERRED.
while the second condition checks:
  status != P2P_SC_SUCCESS &&
  status != P2P_SC_FAIL_INFO_CURRENTLY_UNAVAILABLE &&
  status != P2P_SC_SUCCESS_DEFERRED
Thus, the two conditions are mutually exclusive and 'else if' can be
used if this case.

Delete redundant comparison of msg.wps_config_methods with

already done early in this function. Also, the second comparison

e01281fccc trace: Use explicit alignment requirements to avoid misalignment
64-bit builds with CONFIG_WPA_TRACE=y resulted in the wpabuf pointers
getting misaligned (only 32-bit aligned) and that would result in reads
and writes of unaligned size_t values. Avoid this by indicating explicit
alignment requirement for wpabuf_trace to 8 octets (i.e., there will be
extra four octets of padding in case of 64-bit builds).

Similarly, struct os_alloc_trace resulted in some potential misalignment
cases, e.g., when CONFIG_ACS=y uses a 'long double' variable within
struct hostapd_channel_data. Avoid misalignment issues with explicit
alignment indication.

2da525651d Add backtrace-based error path testing mechanism
The new TEST_FAIL and GET_FAIL control interface commands can be used
similarly to the earlier TEST_ALLOC_FAIL/GET_ALLOC_FAIL design. The new
version is more generic framework allowing any function to be annotated
for failure testing with the TEST_FAIL() macro. This mechanism is only
available in builds with CONFIG_WPA_TRACE_BFD=y and
CONFIG_TESTING_OPTIONS=y. For other builds, the TEST_FAIL() macro is
defined to return 0 to allow the compiler to remove the test code from
normal production builds.

As the first test site, allow os_get_random() to be marked for failing
based on call backtrace.

Fix a condition when Advertised Service Info Attribute is added to

that a 'found' value is increased even if 'test' and 'adv->hash' hashes
are different. As result 'found' may have a non-zero value when an
attribute data length is 0. In this cause an empty attribute is about to
be added. Fixing it by eliminating 'found' and checking 'total_len'
containing a real number of bytes added to Advertised Service Info
Attribute.
