6773de39b1 nl80211 driver: correctly set the encrypt bit for eapol frames
A recent kernel change led to all EAPOL frames being encrypted rather than
just those for the group handshake. This is due to transmit processing in
the kernel now using the proper interface which would encrypt those frames
with the group key because hostapd wasn't requesting that they not be
encrypted. This changes the nl80211 driver to not request encryption unless
the EAPOL frame should be encrypted.

565861976d Added support for using SHA256-based stronger key derivation for WPA2
IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.

9b71728bba Cleaned up TX callback request processing
Move the use of 802.11 header protocol field into driver_hostap.c since
this is a Host AP driver specific mechanism and other driver wrappers
should not really need to know about it.

5d22a1d5aa IEEE 802.11w: Added association ping
This updates management frame protection to use the assocition ping process

This adds most of the new frame format and identifier definitions from IEEE

replaced with the new two-bit version with MFPC (capable) and MFPR
(required) processing.

271d2830ff Added support for setting VLAN ID for STAs based on local MAC ACL
This allows the accept_mac_file to be used as an alternative for RADIUS
server-based configuration. This is mainly to ease VLAN testing (i.e., no
need to set up RADIUS server for this anymore).

4d4233eaf4 Fixed internal TLSv1 server implementation for abbreviated handshake
When the TLS handshake had been completed earlier by the server in case of
abbreviated handshake, the output buffer length was left uninitialized. It
must be initialized to zero in this case. This code is used by EAP-FAST
server and the uninitialized length could have caused it to try to send a
very large frame (though, this would be terminated by the 50 roundtrip EAP
limit). This broke EAP-FAST server code in some cases when PAC was used to
establish the tunnel.

edd360e170 Do not store dynamic HT IEs in configuration structures
The configuration data should only store the static configuration data and
not dynamic data. In addition, storing HT configuration and state in IEs is
not the easiest way of doing this, so use more convenient data types for
storing configuration and dynamic state. The HT IEs are then generated
based on the static configuration and dynamic state whenever needed.

e7d8003358 EAP-PEAP: Fixed interop issues in key derivation with cryptobinding
It looks like Microsoft implementation does not match with their
specification as far as PRF+ label usage is concerned.. IPMK|CMK is derived
without null termination on the label, but the label for CSK derivation
must be null terminated.

This allows cryptobinding to be used with PEAPv0 in a way that
interoperates with Windows XP SP3 (RC2) and as such, this functionality is
now enabled as an optional addition to PEAPv0.

06726f0bdd EAP-PEAP: Moved EAP-TLV processing into eap_peap.c
EAP-PEAP was the only method that used the external eap_tlv.c server
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.

6affdaee6b Support for RADIUS ACLs with drivers that do not use hostapd MLME
Sam Leffler <sam@errno.com>:
Attached are changes from Chris Zimmerman (cc'd) to allow drivers to handle
radius ACL's.  The patch is against 0.5.10 but I suspect will also apply to
your latest code.  These mods enable radius acl support in freebsd w/ my
vap code.

You may want to do the changes to ieee802_11_auth.c differently as they
currently require all participating drivers to work the same.  You might be
able to check the return value from hostapd_set_radius_acl_auth and use
that to decide whether the alternate code should be run so you can have 1
driver using this stuff while the other does not.

(jm: Added without more dynamic check for now; in addition, none of the
current in-tree driver wrappers actually implement these handlers, so this
is in preparation for future changes)

b6745143e8 hostapd_allowed_address() is called from hostapd_config_reload_sta() with
session_timeout and acct_interim_interval set to NULL.  Without checking
these before accessing, we'd cause a NULL pointer access in this case.  In
ieee802_11.c calls hostapd_allowed_address() with valid pointers.

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.
