0ed57c5ea8 EAP-TEAP server and peer implementation (RFC 7170)
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.

d3a035169b Remove useless NULL comparison for an array
Now that the TLS peer_cert information is provided as a full struct to
handler functions, the altsubject pointer shows up as an array and
causes static analyzers to warn about unnecessary NULL comparison. Get
rid of that comparison now that it is clearly not needed anymore.

f74618cb92 wpa_supplicant: Fix type for ssid->mode comparisons
The ssid->mode is from type enum wpas_mode and all its constants start
with WPAS_MODE_*. Still some of the code sections used the
IEEE80211_MODE_* defines instead of WPAS_MODE_*.

This should have no impact on the actual code because the constants for
INFRA, IBSS, AP and MESH had the same values.

EAP method is required for a credential that matches configured

cbfd0a263d P2P: Force p2p-send-action as the next radio work to execute
This increases the priority of the p2p-send-action radio work, i.e., the
radio work used for transmitting potentially offchannel P2P Action
frames by marking it as the next radio work to execute. This is to avoid
the delay in transmissions due to already queued offchannel radio work
items in the queue. In particular, this means not having to wait for a
pending p2p-scan radio work to be executed before the new P2P Action
frame can be transmitted. This helps in avoiding timeouts on the peer
device when a P2P Action frames is received during other activity on the
device.

2e3bff5919 P2P: Reject p2p-send-action work while other one is pending
The previous implementation rejects the p2p-send-action work while there
is already one in progress (wpas_send_action_cb() has already been
called for it to start operation). Enhance the same to also consider any
p2p-send-action works pending in the radio work (i.e., waiting for that
wpas_send_action_cb() call).

This is considering the current behaviour of P2P to handle the state
corresponding to respective Action frame transmission:
pending_action_state. If a new P2P Action frame transmission is queued
while there is another one already in the queue, the transmit status of
the first frame is wrongly intepreted by the P2P state machine which has
already scheduled/queued another frame for transmission.

d42df8d6ce Fix a regression in storing of external_auth SSID/BSSID
An earlier change in drivers_ops API for struct external_auth broke the
way SSID and BSSID for an external authentication request were stored.
The implementation depended on the memory array being available in the
API struct with a use of memcpy() to copy the full structure even though
when only SSID and BSSID was needed. Fix this by replacing that
easy-to-break storing mechanism with explicit arrays for the exact set
of needed information.

eb3234c07b SAE: Use open authentication to reassociate for PMKSA caching
For reassociation with the same AP wpa_supplicant attempts to use cached
PMKSA. For this purpose PMKID is passed in RSNE in (Re)Association
Request frame. In the case of SAE AP, open authentication shall be used
during reassociation. Otherwise cached PMKID becomes invalid after full
SAE authentication.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However SME-in-driver cases, complete SAE authentication is
performed. As a result, first reassociation attempt fails.

Fix SME-in-driver behavior by reseting authentication algorithm to
WPA_AUTH_ALG_OPEN when reassociating with SAE AP with an existing PMKSA
cache entry.
