This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.
Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.
User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.
When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

pkcs11_engine_path, pkcs11_module_path, load_dynamic_eap) from user
controlled location when starting again. This would allow code from that
library to be executed under the wpa_supplicant process privileges.

Spurious newlines output while writing the config file can corrupt the
wpa_supplicant configuration. Avoid writing these for the network block
parameters. This is a generic filter that cover cases that may not have
been explicitly addressed with a more specific commit to avoid control
characters in the psk parameter.

WPA/WPA2-Personal passphrase is not allowed to include control
characters. Reject a passphrase configuration attempt if that passphrase
includes an invalid passphrase.
This fixes an issue where wpa_supplicant could have updated the
configuration file psk parameter with arbitrary data from the control
interface or D-Bus interface. While those interfaces are supposed to be
accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the passphrase value before passing it to
wpa_supplicant.
This could allow such an untrusted user to inject up to 63 characters of
almost arbitrary data into the configuration file. Such configuration
file could result in wpa_supplicant trying to load a library (e.g.,
opensc_engine_path, pkcs11_engine_path, pkcs11_module_path,
load_dynamic_eap) from user controlled location when starting again.
This would allow code from that library to be executed under the
wpa_supplicant process privileges.

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.

This avoids unnecessary flushing of the PMKSA cache entry and EAP
session data when processing SET_NETWORK commands that set a network
profile parameter to the same value that the parameter already has.
Introduce a new wpa_config_set() and wpa_config_set_quoted() return
value (==1) signifying that the new value being set for the
corresponding field equals to the already configured one so that the
caller can determine that nothing changed in the profile.
For now, this does not cover all the network profile parameters, but
number of the most commonly used parameters are included to cover the
Android use cases where the framework may have issued SET_NETWORK
commands that would have unnecessarily prevented use of PMKSA caching or
EAP fast reauthentication.

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.

Each scan plan specifies the interval between scans and the number

specifies only the interval between scan iterations.

A new network profile configuration parameter max_oper_chwidth=3 can be
used to specify preference to enable 80+80 MHz VHT channel for IBSS. If
that is set, the first 80 MHz segment is specified based on the
frequency parameter in the network profile and the second segment is
selected automatically (which will practically be limited to a single
possibility due to DFS requirements in most countries).

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.

Upon any change in the currently used channels evaluate if a GO should
move to a different operating frequency, where the possible scenarios:
1. The frequency that the GO is currently using is no longer valid,
due to regulatory reasons, and thus the GO must be moved to some
other frequency.
2. Due to Multi Concurrent Channel (MCC) policy considerations, it would
be preferable, based on configuration settings, to prefer Same
Channel Mode (SCM) over concurrent operation in multiple channels.
The supported policies:
- prefer SCM: prefer moving the GO to a frequency used by some other
interface.
- prefer SCM if Peer supports: prefer moving the GO to a frequency
used by some other station interface iff the other station
interface is using a frequency that is common between the local and
the peer device (based on the GO Negotiation/Invitation signaling).
- Stay on the current frequency.
Currently, the GO transition to another frequency is handled by a
complete tear down and re-setup of the GO. Still need to add CSA flow to
the considerations.

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.
