ef626b4d50 Added a workaround for handling TLS compression
Even though we try to disable TLS compression, it is possible that this
cannot be done with all TLS libraries. For example, OpenSSL 0.9.8 does not
seem to have a configuration item for disabling all compression (0.9.9 has
such an option). If compression is used, Phase 2 decryption may end up
producing more data than the input buffer due to compressed data. This
shows up especially with EAP-TNC that uses very compressible data format.

As a workaround, increase the decryption buffer length to (orig_len+500)*3.
This is a hack, but at least it handles most cases. TLS compression should
really be disabled for EAP use of TLS, but since this can show up with
common setups, it is better to handle this case.

fca25ef4b4 Only use SSL_OP_NO_COMPRESSION if it is defined

fe2b7dda02 Fixed fallback to full handshake when server rejects PAC-Opaque
The TLS client changes in ssl3_get_server_hello() were based on the
pre-RFC 5077 version of OpenSSL and they hardcoded s->hit to 1 in case
PAC-Opaque was used. This prevented fallback to full TLS handshake in case
the server rejected PAC-Opaque in ClientHello. The fixed version simplifies
ssl3_get_server_hello() and uses the new RFC 5077 functionality in OpenSSL
(ssl3_check_finished) to allow the state machine handle start of
abbreviated handshake based on the used ticket.

1c156e783d Fixed tls_prf() to handle keys with odd length
The middle byte of the secret (key for PRF) is shared with key halfs in
case the key length is odd. This does not happen in any of the current
tls_prf() uses, but it's better to fix this function to avoid future issues
should someone end up defining a use that uses an odd length for the key.

c454f57379 eapol_test: Allow client IP address to be specified
Allow the user to set the IP address of the eapol_test client. This if
very useful when you have a machine with many interfaces and want to use a
particular one for testing RADIUS connectivity. For instance when I run the
national eduroam proxy I can only connect to other server from a particular
address, an our machine happens to have several IPs. So if I want to run
connectivity tests, I must make sure that my test uses a particular
interface. The -A option allows one to set this).

(jm: cleaned up to use radius configuration structure instead of global
variable for the address and added IPv6 support)

1e4b9da10c Chargeable-User-Identity (RFC 4372) in eapol_test
Implements the Chargable-User-Identity (CUI), as defined in RFC 4372.
Option "-i" causes the eapol_test to send a NUL CUI - which is a request to
send a CUI back. Capital "-I" allows to specify the value of the CUI.
This has been defined for cases where the client wants to reauthenticate.

30680e9332 EAP-TTLS: Fixed implicit challenge derivation to use correct output length
The previous version was deriving unnecessarily large amount of output data
for the implicit challenge. With the TLS PRF, this was not causing any
problems because the output length is not explicitly bound into the
derivation. Anyway, it is better to use the correct output length should
the PRF be ever changed to a one that uses the output length to change the
beginning of the output data.

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.

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.

EAP-PEAP was the only method that used the external eap_tlv.c peer

trivial with such separation. With the TLV processing integrated into

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.

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)
