Denis Kenzior 1b72fe9713 eap: Add eap event_func
This is used to get arbitrary information out of the EAP method.  Needed
for EAP-WSC to signal credential information obtained from the peer.

Other uses include signaling why EAP-WSC failed (e.g. invalid PIN, etc)
and processing of M2D discovery messages.  The information in M2Ds might
be useful to external clients.

Denis Kenzior baf72d7f86 eapol: Move to a single PAE socket
We used to open a socket for each wireless interface.  This patch uses a
single socket with an attached BPF to handle all EAPoL traffic via a
single file descriptor.

Andrew Zaborowski 955c88a64a ie: Consistently set group_management_cipher
RSNE_ADVANCE may return and if it is before the assignment of
info.group_management_cipher, that assignment will be dependent on where
the RSNE ends.

Andrew Zaborowski 316752c5e4 ie: Error in tlv_iter_next if no space to length byte
When parsing the EAPoL-Key key data field we don't strip the 0xdd /
0x00 padding from the decrypted data so there may be trailing padding
after the IE sequence and valgrind will report an invalid read of the
length byte.  Same thing may happen if we're sent garbage.

Denis Kenzior c0de9d1790 eap-wsc: optionally load IV1 & IV2 for debugging
When we send M5 & M7, we need to generate a random IV.  For testing
purposes, the IV can be provided in settings, otherwise it will be
generated randomly.

Denis Kenzior 48c3f4a55a eap-wsc: Store PSK1 & PSK2

Denis Kenzior 9a47f98ccd eap-wsc: Store M2 for future use
We need quite a bit of attributes of M2 for the duration of the WSC
handshake.  Most importantly, we need to use the peer's public key when
processing M4 and M6.  RegistrarNonce is also needed for generating any
ACK/NACK messages as needed.

Also, peer's device attributes such as Model, Manufacturer, etc might be
useful to report upon successful handshake.

Denis Kenzior 39d6acb07d eap-wsc: Don't store AuthKey | KeyWrapKey | EMSK
AuthKey is already uploaded into auth_key_hmac.  KeyWrapKey is now
uploaded into the AES-CBC(128) cipher.  We currently have no use for
EMSK.

So we no longer need to keep the wsc_session_key structure around.

Denis Kenzior 757e4dbb90 wscutil: Prepare for parsing of Encrypted Settings
Encrypted Settings TLVs are structured similarly to the various WSC
messages.  However, they lack a version2 extension field and use a Key
Wrap Authenticator element instead of Authenticator.
