6b1c590ebb Allow TKIP support to be removed from build
Add a build flag CONFIG_NO_TKIP=y to remove all TKIP functionality from
hostapd and wpa_supplicant builds. This disables use of TKIP as both the
pairwise and group cipher. The end result does not interoperate with a
WPA(v1)-only device or WPA+WPA2 mixed modes.

Hardcoded CONFIG_IEEE80211N to be included to clean up implementation.
More or less all new devices support IEEE 802.11n (HT) and there is not

018edec9b2 Remove IAPP functionality from hostapd
IEEE Std 802.11F-2003 was withdrawn in 2006 and as such it has not been
maintained nor is there any expectation of the withdrawn trial-use
recommended practice to be maintained in the future. Furthermore,
implementation of IAPP in hostapd was not complete, i.e., only parts of
the recommended practice were included. The main item of some real use
long time ago was the Layer 2 Update frame to update bridges when a STA
roams within an ESS, but that functionality has, in practice, been moved
to kernel drivers to provide better integration with the networking
stack.

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.

a0bf1b68c0 Remove all PeerKey functionality
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.

station mode WNM is required and there is no need for AP mode WNM.

WNM. This allows binary size to be reduced for builds that require
only the station side WNM functionality.

245fc96e5f FT: New RRB message format
Convert FT RRB into a new TLV based format. Use AES-SIV as AEAD cipher
to protect the messages.

This needs at least 32 byte long keys. These can be provided either
by a config file change or letting a KDF derive the 32 byte key used
from the 16 byte key given.

This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

50bd8e0a90 FT: Replace inter-AP protocol with use of OUI Extended Ethertype
Replace the previously used extension of IEEE 802.11 managed Ethertype
89-0d (originally added for Remote Request/Response in IEEE 802.11r)
with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP
communication. The new design uses a more properly assigned identifier
for the messages.

This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new
hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP),
and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH
protocol.
