32f049b2af EAP-PEAP: Swap MS-CHAP-v2 MPPE keys for EAP-PEAP ISK derivation
Microsoft uses reverse order for MS-MPPE keys in EAP-PEAP when compared to
EAP-FAST derivation of ISK. Swap the keys here to get the correct ISK for
EAP-PEAPv0 cryptobinding. This resolves the cryptobinding interop issue
with WinXP SP3 RC2. However, it looks like MSK derivation does not
interoperate when using cryptobinding, so this code remains disabled for
the time being.

e1a69a0b10 EAP-PEAP: Added preliminary code for PEAPv0 and PEAPv2 cryptobinding
This implementation is complete for PEAPv0 (Microsoft extension), but the
use of cryptobinding is disabled in this version, i.e., this does not
change protocol behavior at all.

Interop tests between hostapd and wpa_supplicant work fine, but there are
some problems in getting hostapd to interoperate with Windows XP SP3 RC2
(peer replies with Result Failure to the attempted cryptobinding). The
implementation will remain disabled until this issue has been resolved.

0ac0e4df1c EAP-PEAP: Moved EAP-TLV processing into eap_peap.c
EAP-PEAP was the only method that used the external eap_tlv.c peer
implementation. This worked fine just for the simple protected result
notification, but extending the TLV support for cryptobinding etc. is not
trivial with such separation. With the TLV processing integrated into
eap_peap.c, all the needed information is now available for using
additional TLVs.

a865bd5031 Some cleanup for the new driver wrapper for PS3
wpa_printf() does not use '\n'. Fixed set_wpa_key() to allocate buf for
ASCII passphrase case.

b5a357b476 Add support for PS3 Linux wireless driver
This adds support for PS3 wireless to wpa_supplicant.

Although PS3 wireless driver is designed to conform the WEXT standard
as much as possible, unfortunately the wext driver wrapper of
wpa_supplicant can not support PS3 wireless fully because:

 - PS3 wireless driver uses private WEXT ioctls for accepting PSK of
   WPA-Personal from the userland.
   WEXT does not specify the way to do it.

 - The association and 4-way handshake are done by PS3 virtual
   wireless device. The guest OSes can not interfere it.

 - No EAPOL frames are allowed to go outside of the
   hypervisor/firmware nor come from. They are eaten by the firmware.

Thus I needed to make a new driver wrapper for PS3 wireless.

This patch can be applied against the latest 0.6.x tree.

658d166297 FT: Use correct BSSID when deriving PTK and verifying MIC
The old version was using struct wpa_sm::bssid which is not necessarily
updated to point to the correct target address when doing over-the-air FT
since the address is used before the association has actually been
completed.

58a98fb027 Delete PTK SA on (re)association if this is not part of a Fast BSS
Transition. This fixes a potential issue where an incorrectly behaving AP
could send a group key update using the old (now invalid after reassociate)
PTK. This could also happen if there is a race condition between reporting
received EAPOL frames and association events.

c80a74d70c TNC: Integrated TNC support into EAP-TTLS server

after a successful authentication.

35f39ac4c9 TNC: Fixed TNC when using EAP-TTLS with non-EAP Phase 2
Need to process EAP AVP after the non-EAP Phase 2 method. In addition,
EAP-TTLS/MSCHAPv2 needs special code for handling the starting of TNC after
extra roundtrip of MSCHAPv2 success message.

7db0fca522 TNC: Integrated TNC support into EAP-FAST server
Tunneled EAP sequence is now used to perform both the authentication (e.g.,
using EAP-GTC) and TNC validation (EAP-TNC) inside the EAP-FAST tunnel if
TNC has been enabled.

da08a7c732 TNC: Added preliminary TNC implementation for hostapd
This adds EAP-TNC method and TNCS (IF-IMV and IF-TNCCS) functionality.
There is no integration with EAP-TTLS and EAP-FAST at this point, so this
version is not yet suitable for real use (i.e., EAP-TNC can only be tested
outside a tunnel which is not an allowed configuration for deployment).
However, the basic TNCS functionality is more or less complete and this
version seems to interoperate with wpa_supplicant.

7914585fe0 EAP-FAST: Cleaned up TLV processing and added support for EAP Sequences
Number of TLVs were processed in groups and these cases were now separated
into more flexible processing of one TLV at the time. wpabuf_concat()
function was added to make it easier to concatenate TLVs. EAP Sequences are
now supported in both server and peer code, but the server side is not
enabled by default.

one roundtrip from normal authentication.

This allows associations to be denied if the STA tries to use too large
listen interval. The default value is 65535 which matches with the field

These are expected in most cases and there is no need to confuse users
with the messages in stderr (perror was used here). These are now only
shown in debug output and EOPNOTSUPP errors are silently ignored.
