1fd4b0db7c Fix EAPOL/EAP reauthentication with external RADIUS server
The EAP server state machine will need to have special code in
getDecision() to avoid starting passthrough operations before having
completed Identity round in the beginning of reauthentication. This was
broken when moving into using the full authenticator state machine from
RFC 4137 in 0.6.x.

24466b188a WPS: Convert WEP key to hex
Use of hex is safer since the enrollee may configure AP with 5 or 13
random octets of binary data as the key.

d5e2b2d274 WPS UFD: Use pre-configured DH keys only with OOB
The old behavior of generating new DH keys can be maintained for non-OOB
cases and only OOB (in this case, with UFD) will use the pre-configured
DH keys to allow the public key hash to be checked.

7cbf51bbd8 WPS UFD: Remove oob_dev pointer from wps_context
This pointer and the especially the oob_dev->device_path does not remain
valid, so better not save it any longer than it is needed.

390cd3105d WPS UFD: Make build conditional on CONFIG_WPS_UFD=y
Not all embedded devices have USB interface and it is useful to be able
to remove unneeded functionality from the binary. In addition, the
current implementation has some UNIX specific calls in it which may make
it not compile cleanly on all target systems.

46bdb83acd WPS: Add UFD support (USBA out-of-band mechanism)
This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following UFD methods can be used:
- Enrollee PIN with UFD
- Registrar PIN with UFD
- unencrypted credential with UFD

Encrypted credentials are not supported.

Enrollee side operation:
wpa_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

wpa_cli -i ath0 wps_oob ufd /mnt/ pin-r

Registrar side operation:
./hostapd_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

hostapd_cli -i ath0 wps_oob ufd /mnt/ cred

a9aca28ba3 Fix WPS in non-WPA modes with drivers that implement MLME
Need to set WLAN_STA_WPS and WLAN_STA_MAYBE_WPS flags even if WPA is not
enabled. This allows open and static WEP modes to initiate WPS
negotiation with madwifi-like drivers.

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

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

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
I think that the "radius" pointer in the structure hostapd_config is
never used; when the configuration is parsed the related data is stored
in hostapd_bss_config's "radius" var.

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

device password (AP PIN), lock the AP setup after four failures. This

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
instead pass the WPS attributes for an external program to process over
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.
