It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.
Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.
This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.
With this new backend, splitting up credentials and configuration
becomes trivial:
# /etc/wpa_supplicant/wpa_supplicant.conf
ext_password_backend=file:/etc/wpa_supplicant/psk.conf
network={
ssid="foobar"
psk=ext:foobar
}
# /etc/wpa_supplicant/psk.conf
foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b
Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

The function wpa_config_get_line() is used by the wpa_supplicant config
file parser to retrieve the next non-comment non-blank line. We'll need
the same kind of functionality to implement the file-based external
password backend, so as a preparatory step this commit extracts the
function into its own standalone file in the utils package.
No functional changes are expected from this commit.

Add PASN implementation to wpa_supplicant
1. Add functions to initialize and clear PASN data.
2. Add functions to construct PASN Authentication frames.
3. Add function to process PASN Authentication frame.
4. Add function to handle PASN frame TX status.
5. Implement the station side flow processing for PASN.
The implementation is missing support for wrapped data and PMKSA
establishment for base AKMs, and only supports PASN authentication or
base AKM with PMKSA caching.
The missing parts will be added in later patches.

Android has a mechanism to extend the driver interface in vendor
specific ways. This implementation of the vendor interface is done in
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB). Extend this to allow the vendor
events to be provided to this library to facilitate the event
processing.
Introduce a new board configuration via
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB_EVENT) rather than reusing
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB) to enable this event handling in the
private library. This is to avoid compilation issues for
wpa_driver_nl80211_driver_event() with the already existing private
library implementations defined with
$(BOARD_WPA_SUPPLICANT_PRIVATE_LIB).

This adds support for a new EAP method: EAP-TEAP (Tunnel Extensible
Authentication Protocol). This should be considered experimental since
RFC 7170 has number of conflicting statements and missing details to
allow unambiguous interpretation. As such, there may be interoperability
issues with other implementations and this version should not be
deployed for production purposes until those unclear areas are resolved.
This does not yet support use of NewSessionTicket message to deliver a
new PAC (either in the server or peer implementation). In other words,
only the in-tunnel distribution of PAC-Opaque is supported for now. Use
of the NewSessionTicket mechanism would require TLS library support to
allow arbitrary data to be specified as the contents of the message.

There is no existing mechanism for setting up AP mode functionality with
FT enabled, so there is not really much point in having a build option
for trying to include the AP-to-AP FT functionality into wpa_supplicant
either. Since this build option results in failures to complete the
build, simply remove it completely. This can be restored if there is
ever desire to enable FT functionality in wpa_supplicant controlled AP
mode.

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, CONFIG_WNM enabled build that supports WNM for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode WNM is required and there is no need for AP mode WNM.
Add support to differentiate between station mode WNM and AP mode
WNM in wpa_supplicant builds by adding CONFIG_WNM_AP that should be
used when AP mode WNM support is required in addition to station mode
WNM. This allows binary size to be reduced for builds that require
only the station side WNM functionality.
