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.
It seems that WFA WPS spec says that default key index should be 1 (not
0). I think this meas that WEP key indexes region is not from 0 to 3,
but from 1 to 4 in WPS. At least WRT610N implemented it this way.
These flags are used to mark which values (level, noise, qual) are
invalid (not available from the driver) and whether level is using dBm.
D-Bus interface will now only report the values that were available.
If the driver reports support for more than one SSID per scan request,
optimize scan_ssid=1 operations in ap_scan=1 mode. This speeds up
scanning whenever scan_ssid=1 is used since the broadcast SSID can be
included in every scan request and if driver supports more than two
SSIDs in the scan request, the benefits are even larger when multiple
networks have been configured with ap_scan=1.
This is also cleaning up wpa_supplicant_scan() function by moving code
around so that the SSID list is not processed unnecessarily if the
operation mode does not need this.
This can be used to provide support for scanning multiple SSIDs at a
time to optimize scan_ssid=1 operations. In addition, Probe Request IEs
will be available to scan2() (e.g., for WPS PBC scanning).
For example, -Dnl80211,wext could be used to automatically select
between nl80211 and wext. The first driver wrapper that is able to
initialize the interface will be used.
The driver wrappers can now inform wpa_supplicant how many SSIDs can
be used in a single scan request (i.e., send multiple Probe Requests
per channel). This value is not yet used, but it can eventually be used
to allow a new scan command to specify multiple SSIDs to speed up
scan_ssid=1 operations. In addition, a warning could be printed if
scan_ssid=1 is used with a driver that does not support it
(max_scan_ssids=0).
Split the auth=none option into three: open, WEP, WEP with shared key to
allow the user specify WEP with shared key authentication. In addition,
fix static WEP key edits to be enabled only when using static WEP keys
(i.e., not for IEEE 802.1X).
wpa_supplicant should not send a dbus reply as response to a method call
if no reply was requested by the caller. Sending a reply even if not
requested is basically no problem but triggers dbus warnings like the
one below.

Build EAP-WSC dynamically does not make much sense and with the
dependencies to WPS code from number of places resolving this is not
trivial. It is simpler to just remove this option.
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.
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.
If wpa_supplicant is started with -u but the DBus service is already
registered wpa_supplicant will bail out. However, it will segfault
in wpa_supplicant_deinit because global->drv_priv wasn't allocated
yet.

This is based on a patch from Pavel Roskin <proski@gnu.org>, but with
the WIRELESS_DEV part removed instead of moved since it does not apply
anymore. Additional note on client MLME limitations was also added.
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.
If a Registrar tries to configure the AP, but fails to validate the
device password (AP PIN), lock the AP setup after four failures. This
protects the AP PIN against brute force guessing attacks.
Some WPS APs do not set Selected Registrar attribute to 1 properly when
using an external Registrar. Allow such an AP to be selected for PIN
registration after couple of scan runs that do not find APs marked with
Selected Registrar = 1. This allows wpa_supplicant to iterate through
all APs that advertise WPS support without delaying connection with
implementations that set Selected Registrar = 1 properly.
The default interval is now 5 seconds (used to be 1 second for
interactive mode and 2 seconds for wpa_cli -a). The interval can be
changed with -G<seconds> command line option.
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.
The wps_cred_process option can be used to configure wpa_supplicant to
send received Credential attributes for external processing over
ctrl_iface and dbus. This allows external programs to update their
configuration when WPS is used to provision new networks.
This makes it easier to pass the credential data to external programs
(e.g., Network Manager) for processing. The actual use of this data is
not yet included in hostapd/wpa_supplicant.
The current implementation does not support WPA/WPA2-Enterprise
credentials. Ignore any credential that is using unsupported
authentication type to avoid potential issues with partially configured
network blocks.
Must not set pairwise_cipher/group_cipher for non-WPA/WPA2 networks
since the configuration parser is going to reject such values. In
addition, should not limit group_cipher to just TKIP or TKIP|CCMP just
in case the AP is using WEP as the group cipher. Default group_cipher
value can be used for all cases.
