When wpa_supplicant is running on a Linux interface that is configured in
promiscuous mode, and it is not a member of a bridge, incoming EAPOL
packets are processed regardless of the Destination Address in the frame.
As a consequence, there are situations where wpa_supplicant replies to
EAPOL packets that are not destined for it.
This behavior seems undesired (see IEEE Std 802.1X-2010, 11.4.a), and can
be avoided by attaching a BPF filter that lets the kernel discard packets
having pkt_type equal to PACKET_OTHERHOST.

Previously we set this flag to one in wpa_supplicant_init_iface() if
Wi-Fi controller does not have a dedicated P2P-interface.
This setting had effect only in scope of wpa_supplicant_init_iface() and
it contradicts with comment to struct wpa_interface::p2p_mgmt field.
This comment says that this flag is used only if Wi-Fi controller has
dedicated P2P-device interface.
Also it contradicts with usage of similiar p2p_mgmt field in struct
wpa_supplicant. Again struct wpa_supplicant::p2p_mgmt is set only for
dedicated P2P-device interface.
After this change wpa_interface become input argument to
wpa_supplicant_init_iface() that we are not modifying.

If a DPP_STOP_LISTEN call happens to be received when there is a pending
gas-query radio work that has not yet been started, it was possible for
gas_query_stop() to go through gas_query_done() processing with
gas->work == NULL and that ended up with the pending GAS query getting
freed without removing the pending radio work that hold a reference to
the now freed memory. Fix this by removing the pending non-started radio
work for the GAS query in this specific corner case.

The special case of returning from wpa_supplicant_set_suites() when OWE
transition mode profile is used for an open association did not clear
the wpa_ie buffer length properly. This resulted in trying to use
corrupted IEs in the association request and failed association
(cfg80211 rejects the request or if the request were to go out, the AP
would likely reject it).

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.

The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.
Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.
