6d7fb6918d Add new driver wrapper for the Atheros driver
This uses similar, but not identical, interface to madwifi. It is easier
to keep this separate to avoid conflicts with potential changes in the
driver interfaces.

dbdf58b053 driver_nl80211: Fix STA accounting data collection
TX/RX bytes are now reported correctly (typo ended up leaving TX bytes
uninitialized and set RX bytes value to use correct TX bytes). TX/RX
packet counts are not yet available from kernel, so we have to clear the
values to avoid reporting bogus data.

34a6c94178 WPS: Fix clearing of WPS IE with madwifi driver
On WPS init/deinit process, the hostapd clears it's own WPS IE
with 0 length WPS IE. But it fails. Because the parameter to
ioctl is too short. Then hostapd prints a below message.

ioctl[IEEE80211_IOCTL_SET_APPIEBUF]: Invalid argument

915c1ba3c5 WPS UPnP: Added support for multiple external Registrars

e1bad1cd7d UPnP: Workaround bogus NewWLANEventMAC in PutWLANResponse
It looks like Intel wsccmd may send a bogus NewWLANEventMAC
(11:22:33:44:55:66) when acting as an wired external Registrar. Work
around this by going through all STAs if the address does not match and
pick the STA that is in an ongoing WPS registration.

b77eab282a Explicitly link against libdl when including TNC support
If you don't choose OpenSSL as TLS implementation and choose to enable
CONFIG_EAP_TNC you have to link against libdl. The OpenSSL libraries
implicitly link against them, so this might be a reason why it wasn't
noticed yet. I assume the same applies to hostapd.

42f1ee7d1f Fixed scan buffer increasing with WEXT
We can now handle up to 65535 byte result buffer which is the maximum
due to WEXT using 16-bit length field. Previously, this was limited to
32768 bytes in practice even through we tried with 65536 and 131072
buffers which we just truncated into 0 in the 16-bit variable.

This more or less doubles the number of BSSes we can received from scan
results.

e7e9c46e55 Use better examples for MadWifi path in defconfig, clarify comments
MadWifi is unlikely to be in ../head relative to hostapd or
wpa_supplicant, as it would be inside the hostap git repository.
MadWifi sources are more likely to be in a directory called "madwifi"
and residing outside the hostap repository.  Using "madwifi" also
demonstrates that the top-level madwifi directory is needed.

5eb4e3d024 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
Try to match PRI/SEC channel with neighboring 20/40 MHz BSSes per
IEEE 802.11n/D7.0 11.14.3.2. This is not yet complete implementation,
but at least some parts of the 40 MHz coex are improved.

40 MHz operation maybe rejected (i.e., fall back to using 20 MHz) or
pri/sec channels may be switched if needed.

c9c3eafacb Remove unused variable from struct hostapd_config

f620268f13 WPS: Add support for external Registrars using UPnP transport
This adds mostly feature complete external Registrar support with the
main missing part being proper support for multiple external Registrars
working at the same time and processing of concurrent registrations when
using an external Registrar.

This code is based on Sony/Saice implementation
(https://www.saice-wpsnfc.bz/) and the changes made by Ted Merrill
(Atheros) to make it more suitable for hostapd design and embedded
systems. Some of the UPnP code is based on Intel's libupnp. Copyrights
and licensing are explained in src/wps/wps_upnp.c in more detail.

1e14526571 Use Data::Data only with Host AP driver; mac80211 can use Data::Nullfunc
The inactivity poll was originally supposed to use Data::Nullfunc, but
due to Prism2/2.5/3 firmware issues, this was changed to an empty
Data::Data frame. mac80211 does not have such an issue, so change the
inactivity poll frame to be Data::Nullfunc by default and use the
Data::Data workaround only with Host AP driver.

f01a6b1e3e driver_nl80211: Fixed inactivity poll status processing
Previous version was discarding TX status for FromDS data frames, but
those are the exact ones that we need to check for inactivity poll to
work, i.e., they are TX status reports for injected data frames.

In addition, remove the debug printing of TX status for data frame since
that could fill up the debug output if kernel-side filtering cannot be
used with monitor interface.

9616af520b driver_nl80211: use Linux socket filter to improve performance

3b2cf800af WPS: Lock AP Setup on multiple AP PIN validation failures

a60e7213e1 Fixed WPS with open and shared WEP networks
Do not initialize EAPOL state machine for the STA when hostapd is
configured to use WPS with open or shared WEP networks. This allows the
STA to use EAPOL-Start to indicate it wants to start WPS in such a case
and hostapd does not end up running through EAPOL authentication timeout
and disconnecting the STA if WPS is not used.

There was already code for starting EAPOL state machines based on
received EAPOL packets, but that was not working properly since
portEnabled was not set to TRUE on that code path. This is now fixed,
too.

aabe26a136 WPS: Added option to disable AP auto-config on first registration
This operation can now be moved into an external program by configuring
hostapd with wps_cred_processing=1 and skip_cred_build=1. A new
ctrl_iface message (WPS-REG-SUCCESS <Enrollee MAC addr> <UUID-E>) will
be used to notify external programs of each successful registration and
that can be used as a tricker to move from unconfigured to configured
state.

d745c7cc1a Added wps_cred_processing configuration option for hostapd
This behaves like the one in wpa_supplicant, i.e., hostapd can be
configured not to process new credentials (AP settings) internally and

ctrl_iface.

adddffd129 Fixed MFP Association Comeback mechanism to use Timeout Interval IE
The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.

805e6dc663 Disconnect the STA if EAP timeout is reached
There is not really much else the Authenticator can do if it does not
receive valid EAP response from the Supplicant/EAP peer. EAP-Failure
would need to be sent before trying to start again with
EAP-Request/Identity, but that is not allowed before the EAP peer
actually replies. Anyway, forcing a new association is likely to clean

caused the peer not to be able to reply in the first place.

8e09c6d253 Fixed retransmission of EAP requests if no response is received
It looks like this never survived the move from IEEE 802.1X-2001 to
IEEE 802.1X-2004 and EAP state machine (RFC 4137). The retransmission
scheduling and control is now in EAP authenticator and the
calculateTimeout() producedure is used to determine timeout for
retransmission (either dynamic backoff or value from EAP method hint).

The recommended calculations based on SRTT and RTTVAR (RFC 2988) are not
yet implemented since there is no round-trip time measurement available
yet.

This should make EAP authentication much more robust in environments
where initial packets are lost for any reason. If the EAP method does
not provide a hint on timeout, default schedule of 3, 6, 12, 20, 20, 20,
... seconds will be used.

65d50f0ac6 Add RADIUS server support for identity selection hint (RFC 4284)
Previously, only the delivery option 1 from RFC 4284
(EAP-Request/Identity from the AP) was supported. Now option 3
(subsequent EAP-Request/Identity from RADIUS server) can also be used
when hostapd is used as a RADIUS server. The eap_user file will need to
have a Phase 1 user entry pointing to Identity method in order for this
to happen (e.g., "* Identity" in the end of the file). The identity hint
is configured in the same was as for AP/Authenticator case (eap_message
in hostapd.conf).

bae61562a4 Cleaned up EAPOL-Key timeout processing
dot11RSNAConfigGroupUpdateTimeOut and
dot11RSNAConfigPairwiseUpdateTimeOut MIB variables were only used in
draft versions of IEEE 802.11i, so rename these in order not to use
confusing name here.

Replaced EAPOL-Key timeout to use following timeouts (in
milliseconds): 100,1000,1000,1000 (this was 1000,1000,1000,0). There
is no point in sending out the final EAPOL-Key frame which would be
immediately followed by disconnection. After the change to allow
response to any pending EAPOL-Key frame, it is fine to send the first
retransmission quickly to avoid long wait in cases where Supplicant
did not receive the first frame for any reason. The new sequence will
still provide 3.1 seconds of time to get any response frame, so this
does not reduce the previous time.

47f72245e2 Do not allow HT with WPA/WPA2 to be enabled without CCMP

22a299ee9d Improve EAPOL-Key handshake stability with retransmitted frames
Accept response to any pending request, not just the last one. This
gives the Supplicant more time to reply since hostapd will now allow up
to three seconds for the reply to the first EAPOL-Key frame transmission
(and two seconds for the first retry and one second for the last) while
the previous version invalidated any old request immediately when
sending a retransmitted frame.

If the Supplicant replies to more than one request, only the first reply
to arrive at the Authenticator will be processed. As far as the
Supplicant is concerned, this behavior does not differ from the previous
one except for being less likely to cause unneeded retransmissions of
EAPOL-Key frames.

This can help in cases where power saving is used when the group key is
rekeyed or when there is excessive traffic on the channel that can delay
(or drop) EAPOL-Key frames.

8c37556cd1 Add a starting point for EAP-AKA' (draft-arkko-eap-aka-kdf-10)
This is just making an as-is copy of EAP-AKA server and peer
implementation into a new file and by using the different EAP method
type that is allocated for EAP-AKA' (50). None of the other differences
between EAP-AKA and EAP-AKA' are not yet included.

It is likely that once EAP-AKA' implementation is done and is found to
work correctly, large part of the EAP-AKA and EAP-AKA' code will be
shared. However, it is not reasonable to destabilize EAP-AKA
implementation at this point before it is clearer what the final
differences will be.
