James Prestwood 00fddaa868 dpp-util: add dpp_configuration_new/dpp_configuration_to_json
Allows creating a new configuration object based on settings, ssid,
and akm suite (for configurator role) as well as converting a
configuration object to JSON.

James Prestwood d3fca54a7e dpp-util: pass actual ad_size, not hard coded '2'. 2021-12-20 17:04:21 -06:00
James Prestwood c42080fe28 dpp: use frame data directly in unwrap for config response
Rather than hard coding ad0, use the actual frame data. There really
isn't a reason this would differ (only status attribute) but just
in case its better to use the frame data directly.

James Prestwood d2240c4a62 dpp: handle protocol errors in ROC timeout
This is a standing TODO of properly handling these timeouts but
for now just treat any ROC timeout as an error if authenticating
or configuring.

James Prestwood 926c8bb9bd dpp: add support for configuration protocol
This is a minimal implementation only supporting legacy network
configuration, i.e. only SSID and PSK/passphrase are supported.

Missing features include:
 - Fragmentation/comeback delay support
 - DPP AKM support
 - 8021x/PKEX support

James Prestwood 59a5cf3de4 dpp: add DPP authentication protocol
This implements the DPP protocol used to authenticate to a
DPP configurator.

Note this is not a full implementation of the protocol and
there are a few missing features which will be added as
needed:

 - Mutual authentication (needed for BLE bootstrapping)
 - Configurator support
 - Initiator role

James Prestwood 992deb36d4 dpp-util: add dpp_parse_configuration_object
This parses the configuration JSON object from the configuration
response. Only a minimal configuration object is supported for
now.

James Prestwood 683d3a3f04 dpp: send presence announcements on StartEnrollee
The presence procedure implemented is a far cry from what the spec
actually wants. There are two reason for this: a) the kernels offchannel
support is not at a level where it will work without rather annoying
work arounds, and b) doing the procedure outlined in the spec will
result in terrible discovery performance.

Because of this a simpler single channel announcement is done by default
and the full presence procedure is left out until/if it is needed.

James Prestwood 484dea8d7a offchannel: always use -ECANCELED for cancelation
info->error gets reset to zero on a successful ROC callback
which was getting used for cancelation.

James Prestwood 4a8a43965f offchannel: always call destroy right away on cancel
The main cancel code path was not calling destroy immediately which
was not consistent with other code paths/APIs.

James Prestwood abfd749335 json: introduce JSON module
This is a minimal wrapper around jsmn.h to make things a bit easier
for iterating through a JSON object.

To use, first parse the JSON and create a contents object using
json_contents_new(). This object can then be used to initialize a
json_iter object using json_iter_init().

The json_iter object can then be parsed with json_iter_parse by
passing in JSON_MANDATORY/JSON_OPTIONAL arguments. Currently only
JSON_STRING and JSON_OBJECT types are supported. Any JSON_MANDATORY
values that are not found will result in an error.

If a JSON_OPTIONAL string is not found, the pointer will be NULL.
If a JSON_OPTIONAL object is not found, this iterator will be
initialized but 'start' will be -1. This can be checked with a
convenience macro json_object_not_found();

James Prestwood d65aaf8740 dpp-util: check return of l_ecc_scalar_get_data
Static analysis was not happy since this return can be negative and
it was being fed into an unsigned argument. In reality this cannot
happen since the key buffer is always set to the maximum size supported
by any curves.

James Prestwood bc36aca98e offchannel: introduce new offchannel module
This module provides a convenient wrapper around both
CMD_[CANCEL_]_REMAIN_ON_CHANNEL APIs.

Certain protocols require going offchannel to send frames, and/or
wait for a response. The frame-xchg module somewhat does this but
has some limitations. For example you cannot just go offchannel;
an initial frame must be sent out to start the procedure. In addition
frame-xchg does not work for broadcasts since it expects an ACK.

This module is much simpler and only handles going offchannel for
a duration. During this time frames may be sent or received. After
the duration the caller will get a callback and any included error
if there was one. Any offchannel request can be cancelled prior to
the duration expriring if the offchannel work has finished early.

Andrew Zaborowski 7ecdee6eaa autotests: p2p: Make waiting for dhclient more reliable
Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply.  Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start.  Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.

James Prestwood 7103bda058 netdev: always honor disconnect events if issued by AP
The disconnect event handler was mistakenly bailing out if FT or
reassociation was going on. This was done because a disconnect
event is sent by the kernel when CMD_AUTH/CMD_ASSOC is used.

The problem is an AP could also disconnect IWD which should never
be ignored.

To fix this always parse the disconnect event and, if issued by
the AP, always notify watchers of the disconnect.

James Prestwood 44faa81a06 auto-t: iwd.py: use args[0] for station debug interface
Passing *args, **kwargs into StationDebug ended up initializing the
class with Station properties since devices can be initialized from
existing property dictionaries. Since the object path is all
StationDebug needs, pass args[0] instead.
