It is possible that l2_packet is not used with wpa_supplicant
in some cases, so better make sure we do not end up notifying
l2_packet code about authentications unless it was actually
initialized in the first place.
The pairwise cipher field is supposed to be little endian, but the
message building functions did not swap the bytes on big endian
hosts while the message processing functions did. Fix this by using
little endian byte order in both places.
Store list of all discovered BSSes in the ESS and on which frequencies
they have been seen. Use this information to dynamically generated the
list of channels for background scans.
It looks like 10.6.3 and 10.6.4 do not like to receive Network Key
with WPA passphrase while PSK format still works. Use peer information
from M1 to figure out whether the Enrollee is likely to be OS X and
if so, force PSK format to be used for Network Key.
Some frequent debug prints are of limited use and make debug output
difficult to read. Make them use a new debug level so that -dd
provides more readable output (-ddd can now be used to enable
the excessive debug prints).
The length of the prime was used incorrectly and this resulted
in WPS DH operation failing whenever the public key ended up having
leading zeros (i.e., about every 1/256th time).
The AP configuration may change after provisioning, so it is better
not to use the current security policy to prioritize results. Instead,
use WPS Selected Registrar attribute as the main sorting key and use
signal strength next without considering security policy or rate sets.
The non-WPS provisioning case remains as-is, i.e., this change applies
only when trying to find an AP for WPS provisioning.
Some deployed implementations do not include the mandatory Network
Key attribute when a WPS Credential is for an open network. Allow
this to improve interoperability since the actual key value is not
really needed for open networks.
Addition of the background scanning mechanism in commit
60b94c9819 moved the scan trigger
into a new function that was also incrementing the scan_runs
counter, but the removal of the previous scan_runs incrementation
was forgotten from that patch. This counter should only be updated
into a single location, so remove the old one. This improves AP
selection for WPS provisioning by not skipping some of the initial
scans.
Replace use of rfkill block event with rtnetlink ifdown. This makes
the design more robust since the rfkill event could have been for
another interface while the rtnetlink events are already filtered
based of ifindex. In addition, the new design handles other than
rfkill-triggered ifdown/ifup events, too. rfkill unblocked event
is still needed to try to set the interface back up. If the unblock
was for another interface, ifup will fail and the driver state is
not changed.
Some of the driver wrappers need to get set_ieee8021x() call before
they can configure keys. Reorder the operations in the reloading
of configuration case to match with that expectation.
Setting IEEE80211_PARAM_AUTHMODE to IEEE80211_AUTH_AUTO ends up enabling
Privacy mode in the driver. We need to clear that to allow hostapd to be
reconfigured into open mode.
wps_er_config can now be used to configure an AP. It is similar to
wps_er_learn, but instead of only learning the current AP settings,
it continues to send M8 with the new settings for the AP.
wps_er_start command now takes an optional parameter that can be used
to configure a filter to only allow UPnP SSDP messages from the
specified IP address. In practice, this limits the WPS ER operations
to a single AP and filters out all other devices in the network.
When starting the protocol run with an Enrollee, clone the AP Settings
and replace the AP MAC Address with the Enrollee MAC Address so that the
correct value is then used in the Credential attribute in M8.
If the associating station indicates that it is intents to use WPS
by including WPS IE in (Re)Association Request frame, include WPS IE
in (Re)Association Response frame.
There may be more than one attribute of same type (e.g., multiple DC
attributes), so the code needs to be able to handle that. Replace the
fixed structure with an array of attributes.
This avoids an invalid D-Bus call during interface initialization.
The wpa_state change can happen before the D-Bus interface is set up,
so we must be preparted to handle this early event signal. In theory,
it should be possible to reorder initialization code to make sure
D-Bus signals are ready, but that would likely require quite a bit of
code restructuring, so it looks like a safer option for now is to just
skip the early event.
Previous version driver_bsd.c switches the channel in
wpa_driver_bsd_associate(). This patch changes it to use set_freq().
I have tested this patch on FreeBSD 8.0/NetBSD 5.0.2 with hostapd,
wpa_supplicant(AP) and wpa_supplicant(STA).
The wpa_supplicant compilation with CONFIG_AP option and without
CONFIG_IEEE80211R, CONFIG_WPS, NEED_SME, CONFIG_CLIENT_MLME options
results in following messages.
../src/ap/drv_callbacks.o: In function `hostapd_notif_assoc':
../src/ap/drv_callbacks.c:59: undefined reference to
`ieee802_11_parse_elems'
gmake: *** [wpa_supplicant] Error 1
Add a new wpa_supplicant state: interface disabled. This can be used
to allow wpa_supplicant to be running with the network interface even
when the driver does not actually allow any radio operations (e.g.,
due to rfkill).
Allow driver_nl80211.c and driver_wext.c to start while rfkill is in
blocked state (i.e., when ifconfig up fails) and process rfkill
events to block/unblock WLAN.
Use regular expression matches to see if input is not the (now translated?)
string "Select any network" and is a "<network id>: <ssid>" string or the
"all" keyword where that is applicable.
