If the -I<config> argument is used and the referenced configuration file
cannot be parsed, wpa_config_read() ended up freeing the main
configuration data structure and that resulted in use of freed memory in
such an error case. Fix this by not freeing the main config data and
handling the error case in the caller.

This allows a separate configuration parameter (imsi_identity) to be
used in EAP-SIM/AKA/AKA' profiles to override the identity used in MK
derivation for the case where the identity is expected to be from the
last AT_IDENTITY attribute (or EAP-Response/Identity if AT_IDENTITY was
not used). This may be needed to avoid sending out an unprotected
permanent identity information over-the-air and if the EAP-SIM/AKA
server ends up using a value based on the real IMSI during the internal
key derivation operation (that does not expose the data to others).

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.

Previously, the code that writes mesh_rssi_threshold to a network block
always executes, but the code that reads it from network block and the
code that initializes it to a default value in a new network block are
inside #ifdef CONFIG_MESH. As a result when writing a config file it
will write mesh_rssi_threshold (since it has a non-default value) and
later fail to read the network block.
Fix this by moving the write code under #ifdef CONFIG_MESH as well.
Note, network blocks which already have mesh_rssi_threshold because of
the bug will still fail to read after the fix.

IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS.
wpa_supplicant used to use the actual BSSID value for all such frames
regardless of whether the destination STA is a member of the BSS.
P2P does not follow this rule, so P2P Public Action frame construction
must not be changed. However, the cases using GAS/ANQP for non-P2P
purposes should follow the standard requirements.
Unfortunately, there are deployed AP implementations that do not reply
to a GAS request sent using the wildcard BSSID value. The previously
used behavior (Address3 = AP BSSID even when not associated) continues
to be the default, but the IEEE 802.11 standard compliant addressing
behavior can now be configured with gas_address3=1.

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.

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.
