9e834fc648 EAP-SIM/AKA: Separate identity for MK derivation
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).

a0bf1b68c0 Remove all PeerKey functionality
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.

c86bef2913 wpa_supplicant: Make GAS Address3 field selection behavior configurable
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.

2a3f56502b Reject SET commands with newline characters in the string values
Many of the global configuration parameters are written as strings

an untrusted user has access to a management software component that
does not validate the value of a parameter before passing it to
wpa_supplicant.

This could allow such an untrusted user to inject 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

This avoids unnecessary flushing of the PMKSA cache entry and EAP

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

commands that would have unnecessarily prevented use of PMKSA caching or

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.

This allows the control interface SET command to be used to update the
sched_scan_plans parameter at runtime. In addition, an empty string can
be used to clear the previously configured plan.

32c02261dd Add support for configuring scheduled scan plans
Add the option to configure scheduled scan plans in the config file.
Each scan plan specifies the interval between scans and the number
of scan iterations. The last plan will run infinitely and thus
specifies only the interval between scan iterations.

usage:
sched_scan_plans=<interval:iterations> <interval2:iterations2> ... <interval>
