ec6acdbb6b EAP-SIM/AKA server: Configurable limit to fast re-authentication
Allow the EAP-SIM/AKA server to be configured to use a smaller limit for
the number of times fast re-authentication can be used before falling
back to running full authentication. This is particularly useful for EAP
peer testing to cover cases when falling back from fast
re-authentication to full authentication in various different cases.

c6268e103f EAP-SIM/AKA server: Allow method specific identity exchange to be skipped
While the EAP-SIM/AKA RFCs recommend against doing this, some deployed
authentication servers use the identity from the EAP-Response/Identity
directly without using an EAP method specific indication (AT_IDENTITY).
Having a capability to configure hostapd EAP server to behave in this
manner helps in increasing testing coverage for the EAP peer
implementation.

1a800a9400 EAP-TEAP server: Allow tunneled EAP method sequence to be optimized
Include the start of the next EAP method in an EAP Payload TLV in the
same message with the Crypto-Binding TLV for the previous EAP method to
get rid of one roundtrip when using more than a single EAP
authentication method within the tunnel. The previous, not optimized,
sequence can still be used with eap_teap_method_sequence=1 for more
complete testing coverage.

5a9bd8a06a EAP-TEAP: Use EAP-FAST-MSCHAPv2 in the tunnel
While RFC 7170 does not describe this, EAP-TEAP has been deployed with
implementations that use the EAP-FAST-MSCHAPv2, instead of the
EAP-MSCHAPv2, way of deriving the MSK for IMSK. Use that design here to
interoperate with other implementations since that seems to be direction
that IETF EMU WG is likely to go with an RFC 7170 update.

This breaks interoperability with earlier hostapd/wpa_supplicant
versions.

364b6500b8 EAP-FAST: Move EAP-MSCHAPv2 special MSK handling into MSCHAPv2
EAP-FAST uses a special variant of EAP-MSHCAPv2 called EAP-FAST-MSCHAPv2
in RFC 5422. The only difference between that and EAP-MSCHAPv2 is in how
the MSK is derived. While this was supposed to be specific to EAP-FAST,
the same design has ended up getting deployed with EAP-TEAP as well.
Move this special handling into EAP-MSCHAPv2 implementation so that it
can be shared for both needs.

87098d3324 build: Put archive files into build/ folder too
This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).

Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.

Note that due to the use of thin archives, this required
building with absolute paths.

722138cd25 build: Put object files into build/ folder
Instead of building in the source tree, put most object
files into the build/ folder at the root, and put each
thing that's being built into a separate folder.

This then allows us to build hostapd and wpa_supplicant
(or other combinations) without "make clean" inbetween.

For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.

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.

gcc 8.3.0 was apparently clever enough to optimize away the previously
used os_memset() to explicitly clear a stack buffer that contains keys
when that clearing happened just before returning from the function.
Since memset_s() is not exactly portable (or commonly available yet..),
use a less robust mechanism that is still pretty likely to prevent
current compilers from optimizing the explicit clearing of the memory
away.
