90f14962ec wpa_supplicant: "don't care" value for pbss in ssid structure
Add a new value 2 to the pbss parameter of wpa_ssid structure, which
means "don't care". This value is used in infrastructure mode to request
connection to either AP or PCP, whichever is available in the scan
results. The value is also used in regular WPS (not P2P group formation)
to make WPS work with devices running as either AP or PCP.

96a26ab744 P2P: Support dedicated P2P_DEVICE without separate group interface
Add support for drivers with dedicated P2P_DEVICE interface, but without
group interface concurrency (only a single netdev is used). With such
devices, wpa_supplicant tried to use the p2p_dev interface instead of
the group interface and most P2P operations failed. Extend
wpa_supplicant to use the primary interface instead of a separate group
interface in such cases.

ba307f8528 P2P: Add a separate pointer to the P2P Device instance
In many places in the code there was a reference to wpa_s->parent to get
from group interface to p2p_dev interface. These places can break if
P2P_DEVICE interface would need to be used with the primary interface as
the group interface, since the parent of the primary interface points to
itself and not the p2p_dev interface.

Fix this by adding a separate "p2pdev" pointer to wpa_supplicant,
it will be the same as parent pointer in most cases but whenever
the primary interface is used as a group interface, change it to
point to the correct p2p_dev interface.

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.

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.

d38c7be0f0 Skip SELECT_NETWORK steps only if already connected or connecting
Commit 2a6f78fbbe ('Do not re-associate on
SELECT_NETWORK to current network') started skipping all SELECT_NETWORK
connection steps if the selected network had already been selected
previously. This happened regardless of whether the connection was
already established. This is not necessarily desirable for all cases
where there is no immediate action to even try to connect (e.g., long
wait for the next scan).

Speed this up by allowing the SELECT_NETWORK operation to get started if
there is no connection or ongoing connection attempt with the selected
network.

e66bcedd3e Do not set own_disconnect_req flag if not connected
This fixes some issues where a disconnection event may get ignored if an
earlier operation to remove or disable a network resulted in an attempt
to disconnect event though no connection was in place.
wpa_s->current_ssid != NULL alone is not sufficient to determine that
there will be a driver event notifying completion of such disconnection
request. Set own_disconnect_req to 1 only if wpa_s->wpa_state is also

4d3be9cdd1 Postpone updating of wpa_s->current_bss till association event
In the case of driver-based BSS selection, a bssid_hint in the connect
request might not result in to the selection of the same BSS. Thus,
postpone the updation of the wpa_s->current_bss till the association
event is received unless the BSSID is forced. This fixes issues where
wpa_s->current_bss may end up being updated to point to the BSS that
wpa_supplicant provided as a hint for a roaming case, but then not
restored if the driver decides to "return" to the current BSS instead.
This could result in some operations (e.g., WNM BSS TM response) not
working properly due to incorrect BSS being identified in
wpa_s->current_bss.

5add410162 WPS: Use shorter authentication timeout during no-SelReg iteration
When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.

e6dd8196e5 Work around Linux packet socket regression
Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge:
respect RFC2863 operational state') from 2012 introduced a regression
for using wpa_supplicant with EAPOL frames and a station interface in a
bridge. Since it does not look like this regression is going to get
fixed any time soon (it is already two years from that commit and over
1.5 from a discussion pointing out the regression), add a workaround in
wpa_supplicant to avoid this issue.

The wpa_supplicant workaround uses a secondary packet socket to capture
all frames (ETH_P_ALL) from the netdev that is in a bridge. This is
needed to avoid the kernel regression. However, this comes at the price
of more CPU load. Some of this is avoided with use of Linux socket
filter, but still, this is less efficient than a packet socket bound to
the specific EAPOL ethertype. The workaround gets disabled
automatically, if the main packet socket interface on the bridge
interface turns out to be working for RX (e.g., due to an old kernel
version being used or a new kernel version having a fix for the
regression). In addition, this workaround is only taken into use for the
special case of running wpa_supplicant with an interface in a bridge.

a7f5271d52 Update pending connect radio work BSS pointer on scan update
It is possible for scan result processing or BSS entry removal to occur
while there is a pending connect or sme-connect radio work with a
previously selected BSS entry. The BSS pointer was previously verified
to be valid, i.e., still point to a BSS entry, at the time the actual
connection operation is started. However, that BSS entry could have
changed to point to another BSS if the old BSS entry was either removed
or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).

Fix this by updated the pending connect radio work data on BSS entry
updates similarly to how the last_scan_res array was updated. If the
selected BSS entry is removed, this will still result in a failed
connection, but reallocated BSS entry is now followed properly and used
when the connection work starts.

f1a613118e P2P: Use only the -m config for P2P management device
Previously, the case of non-netdev P2P management device ended up
pulling in both the main interface (e.g., wlan0) and P2P Device
interface (from command line -m argument) as configuration. Similarly,
the main interface ended up included both configuration files. This is
not really helpful for various use cases, e.g., when permanent P2P group
information is stored in the P2P Devince interface, but it gets
duplicated in the main station interface configuration.

Clean this up by changing the -m<file> argument to replace, not
concatenate, configuration information. In other words, the main station
interface will not read this configuration and the P2P Device interface
(non-netdev) does not read parameters from the station interface
configuration file.

c267753ba2 Add support for using random local MAC address
This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.

This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.

This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.

The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

b08d5fa793 WPS: Set EAPOL workarounds dynamically based on association
Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.

Reduce the default startWhen value from 3 to 2 seconds for non-WPS case
since WPS builds have likely received most testing for the past years
with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else
require the EAPOL-Start to initiate operation after a connection.

VENDOR_ELEM_ADD <frame id> <hexdump of elem(s)>

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.

e3bd6e9dc0 P2P: Use another interface operating channel as listen channel
Performing a P2P Device flow such as p2p_listen or
p2p_find, can degrade the performance of an active interface
connection, if the listen frequency is different than the
frequency used by that interface.

To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change
will be possible only in case that the listen channel is not forced
externally, and will be delayed to a point where the P2P Device
state machine is idle.

The optimization can be configured in the configuration file and
is disabled by default.

In order to prioritize between the currently used frequencies, add
the ability to collect additional data about each used frequency
(if the frequency is used by a station interface or P2P Client)
and when needed select the best frequency, where:

1. Infrastructure interfaces have highest priority
2. P2P Client interfaces have higher priority over AP/GO
