e04019737e GAS client: Make PMF check on RX more consistent
Use the SA field instead of BSSID in the received Action frame to
determine whether PMF has been negotiated with the transmitter. While
these fields are supposed to be same for Public Action frames from an
AP, it would be possible that a frame is received with different values.
The following operations in gas_query_rx() use SA, so do the same for
the PMF check.

0645492e7c WNM: Optimize a single BSS transition management candidate scan
If the BSS Transition Management Request frame includes only a single
candidate and we need to scan for the BSS to get up-to-date information,
use a scan for the known BSSID instead of wildcard BSSID. In addition,
set the SSID in the scan if it is known based on old scan results in the
BSS table. This removes unnecessary Probe Response frames when we are
interested in results from only a single BSS.

b907491281 wpa_supplicant: Basic support for PBSS/PCP
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.

Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.

The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

df9e2c2a55 D-Bus: Don't do <deny send_interface="..." /> in dbus service file
It does more than intended; apart from denying messages to that
particular interface it also denies all messages non-qualified with an
interface globally. This blocks messages completely unrelated to
wpa_supplicant, such as NetworkManager communication with the VPN
plugins.

From the dbus-daemon manual:

  Be careful with send_interface/receive_interface, because the
  interface field in messages is optional. In particular, do NOT
  specify <deny send_interface="org.foo.Bar"/>! This will cause
  no-interface messages to be blocked for all services, which is almost
  certainly not what you intended. Always use rules of the form: <deny
  send_interface="org.foo.Bar" send_destination="org.foo.Service"/>

We can just safely remove those rules, since we're sufficiently
protected by the send_destination matches and method calls are
disallowed by default anyway.

9684c7567e mesh: Fix peer link counting when a mesh peer reconnects
When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.

This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.

Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

83fe38b011 P2P: Fall back to no VHT when starting AP/P2P GO
In cases where the bandwidth is not set when starting an AP/P2P GO,
the code tries to use 160 MHz or 80 MHz channels. As a result, the
AP/P2P GO configuration is set to use these channel widths even if
they are not available, which may results in failing to start the
AP/P2P GO.

Fix this by changing the AP/P2P GO configuration not to use VHT channels
when they are not available. In this case the AP/P2P GO will use a 40
MHz channel, if available, or a 20 MHz channel, if this is the maximum
available width.

Use wpa_bss_get() with the specific Group SSID instead of
wpa_bss_get_bssid_latest() if the SSID is already known. This makes the
P2P join operations more robust in case the frequency of the group was
not yet known and the same P2P Interface Address may have been used in
multiple group instances with an older group entry still present in the

IEEE Std 802.11-2012 11.3.5.4 specifies the PMKID for SAE-derived keys

8fb718a748 GAS: Shorten the duration of the wait for GAS comeback response
When exchanging GAS frames with the AP, the initial response from the AP
may take a while to come, since the AP may need to fetch the info from a
server. The next fragments/comeback response frames should take much
less time since the AP already has all of the info, so the wait time
for these frames can be reduced.

In addition, some drivers, e.g., mac80211, try to combine ROC based flows,
to improve medium utilization. For example, if the requested ROC fits
entirely in a previous requested ROC they can be combined. Thus, reducing
the wait time for the next frames can improve medium utilization.

Shorten the duration of GAS comeback to improve medium utilization and
overall GAS exchange times.

8dd5c1b4e9 HS 2.0: Add a command to retrieve icon with in-memory storage
This adds a new command based Hotspot 2.0 icon retrieval option.

In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
   (if needed, repeat with larger offset values until full icon is
   fetched)
5. DEL_HS20_ICON <bssid> <file-name>

REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.

If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.

Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

SIGNAL_MONITOR THRESHOLD=DD HYSTERESIS=DD command will request signal
strength monitoring events based on there having been requested amount
of drop in the signal strength. The threshold value is the RSSI
threshold in dBm for the event to be sent. 0 threshold can be used to

specify the minimum amount of change before a consecutive event is
reported.

With nl80211 driver interface, these values map to the
NL80211_CMD_SET_CQM command with NL80211_ATTR_CQM_RSSI_THOLD and
NL80211_ATTR_CQM_RSSI_HYST attributes to the driver.

2c0d0ae370 GAS: End remain-on-channel due to delayed GAS comeback request
During the sequence of exchanging GAS frames with the AP, the AP can
request to come back in X amount of time and resend the GAS request.

Previously, wpa_supplicant did not terminate the remain-on-channel
session, but rather waited until the requested comeback delay had
expired, and then tried to send the GAS frame (potentially to save the
time that is required to schedule a new remain on channel flow).

This might cause unnecessary idle time (can be close to 1000 ms) in
which the device might be off-channel. Ending the current
remain-on-channel session and then rescheduling makes better usage of
the time in this case.

End remain-on-channel session due to receiving a delayed GAS comeback
request from the AP.

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.

63502c64e1 P2P: Fix P2P_CANCEL for p2p_in_invitation case
Commit f05cee9714 ('P2P: Clear
p2p_in_invitation on cancel') added a wpas_p2p_cancel() case to call
wpas_p2p_group_formation_failed() if wpa_s->p2p_in_invitation is set.
This is done in a loop going through wpa_s->next pointers. However, the
call here can result in removing the interface and freeing wpa_s. The
following attempt to read wpa_s->next is from freed memory and that can
result in process termination when using a separate P2P group interface
and issuing P2P_CANCEL on a group that was started through re-invocation
of a persistent group.

The recent commit 328f49acfe ('P2P:
Complete group formation on client data connection') "fixed" this by
accident since wpa_s->p2p_in_invitation gets cleared in the sequence
that could hit this issue and this results in P2P_CANCEL getting
rejected. However, the real bug here is in the loop that continues after
possible wpa_s instance deletion. Fix that by breaking out of the loop.

d8a3b66d7f driver: Make setting up AP optional when creating AP interface
When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.

In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.

Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.

5e238cc682 WPS: Reconnect for a failed data connection when STA_AUTOCONNECT is 0
If "STA_AUTOCONNECT 0" has been used to disable automatic connection on

connection after successful WPS handshake, it is possible to hit a case
where wpa_s->disconnected is set to 1 and further attempts to connect
shall stop.

While "STA_AUTOCONNECT 0" is used to disable automatic reconnection
attempts in general, this specific WPS case can benefit from trying
again even with that configuration for a short period of time. Extend
the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to
apply for ignoring disabled STA_AUTOCONNECT immediately after a WPS

73ed03f333 wpa_supplicant: Add GTK RSC relaxation workaround
Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.

Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

67deaa582d l2_packet: Add build option to disable Linux packet socket workaround
Linux packet socket workaround(*) has an impact in performance when the
workaround socket needs to be kept open to receive EAPOL frames. While
this is normally avoided with a kernel that has the issue addressed by
closing the workaround packet socket when detecting a frame through the
main socket, it is possible for that mechanism to not be sufficient,
e.g., when an open network connection (no EAPOL frames) is used.

Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the
workaround. This build option is disabled by default and can be enabled
explicitly on distributions which have an older kernel or a fix for the
kernel regression.

Also remove the unused variable num_rx.

(*) Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596
