762e4ce620 EAP-AKA': Update to RFC 5448
There was a technical change between the last IETF draft version
(draft-arkko-eap-aka-kdf-10) and RFC 5448 in the leading characters
used in the username (i.e., use unique characters for EAP-AKA' instead
of reusing the EAP-AKA ones). This commit updates EAP-AKA' server and
peer implementations to use the leading characters based on the final
RFC.

Note: This will make EAP-AKA' not interoperate between the earlier
draft version and the new version.

An existing persistent group information can now be used to force GO
Negotiation to use the previously used SSID/passphrase from a persistent
group if we become a GO. This can be used as an alternative to inviting
a new P2P peer to join the group (i.e., use GO Negotiation with GO
intent 15 instead of starting an autonomous GO and using invitation),
e.g., in case a GO Negotiation Request is received from a peer while we
are not running as a GO. The persistent group to use for parameters is
indicated with persistent=<network id> parameter to p2p_connect.

c98b83f2d3 P2P: Do not update peer Listen channel based on PD/Invitation
Commits 17bef1e97a and
ffe98dfb88 started using p2p_add_device()
with other frames than just Probe Response frames from scan results.
However, these changes did not take into account that the PD Request
and Invitation Request frames are normally received on the our own
Listen channel, not on the Listen channel of the peer. As such, these
frames must not be used to update Listen channel information for the
peer.

Fix this by letting p2p_add_device() know whether the results are from
scan results and if not, skip the peer table updates that are specific
to Probe Response frames.

31b4961f02 Fix EAP/WPS to PSK transition on reassociation in authenticator
A station may move from EAP/WPS key_mgmt to PSK using re-association. In
practice, this can happen most likely with WPS when the station runs
through the provisioning step (EAP/WPS) followed by PSK authentication.
If a deauthentication event is missed from the station for whatever
reason, the EAPOL authenticator state machine could have been left
running.

This can result in various issues, including unexpected disconnection of
the station while both the 4-way handshake and EAPOL authenticator state
machines (EAP) are running at the same time when the supplicant is
trying to use PSK. Fix this by explicitly clearing EAPOL authenticator
state machine on (re)association if the new association does not use it.

2d43d37ff2 DBus: Add ability to report probe requests
Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify
non-P2P peers (P2P peers are identified via PeerFound signals).

As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.

A small test script is also included.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.
