96750ea5e5 WPS: Clean up Primary Device Type handling
Use shared functions for converting Primary Device Type between binary
and string formats. In addition, use array of eight octets instead of a
specific structure with multiple fields to reduce code complexity.

e90bba4c59 Add cleared deprecation notes on iwl,ndiswrapper,madwifi(sta) wrappers
These driver wrappers should not be used anymore; WEXT should be used
instead. However, there may still be users stuck on older kernel versions
that may require driver specific wrappers, so the source code still
remains in the repository.

19019a84a2 wpa_gui: Only move to WPS tab if inactive/disconnect and AP ready
This removes many of the cases where moving to the WPS tab can be
undesired. It is really only useful if we are not currently connected
and there is an AP available that would likely be able to provide us
network connectivity with use of WPS (active PBC more or selected
registrar set).

When using umask 0077, the control interface directory was left without

asked for the group to be allowed to access the control interface. Fix
this by adding read/execute permissions for group if a specific group is
defined in the configuration. [Bug 199]

1545457e04 wpa_gui-qt4: Fix build with Session Manager disabled in Qt4
When trying to build wpa_gui (Qt4 version) from openembedded it fails
because Qt4 is compiled without session manager and thus wpa_gui fails
to compile.

I attached a patch, that enables compiling without Session Manager (via
preprocessor) if it is not compiled into Qt4; otherwise, it behaves as
it does right now.

I checked to build on my host (Debian unstable, Session Manager
enabled) and openembedded (Session Manager disabled).

This is like wpa_msg(), but the output is directed only to
ctrl_interface listeners. In other words, the output will not be
shown on stdout or in syslog.

Change scan result reporting to use wpa_msg_ctrl() for
CTRL-EVENT-SCAN-RESULTS message at info level and wpa_printf() at
debug level to avoid showing scan result events in syslog in the
common configuration used with NetworkManager.

8fc2fb56e4 wpa_supplicant: new DBus API implementation
This patch implements the new DBus API. Both, the new and the
previous API may work concurrently and may be turned on or off
separately in .config file.
Some features of the new API are:
 - more wpa_supplicant's events are signaled with DBus signals,
 - introspection data (requires libxml2 and may be disabled),
 - CurrentBSS and CurrentNetwork properties,
 - PropertyChanged signal for most of properties,
 - Relatively easy to extend.
.config options for the new API are: CONFIG_CTRL_IFACE_DBUS_NEW=y and
CONFIG_CTRL_IFACE_DBUS_INTRO=y for introspection.

This commit misses couple of parts from the full implementation
(these are still under review):
- fetching all configuration parameters for learning WPS information
- scan result BSS add/remove notification (register_bss() and
  unregister_bss() notification callbacks)

d27df100b5 Allow driver and ctrl_interface parameters to be overridden
New wpa_supplicant command line options -o<driver> and -O<ctrl> can
now be used to override the parameters received in add interface
command from dbus or global ctrl_interface. This can be used, e.g.,
to enable control interface when using NetworkManager (add
-O/var/run/wpa_supplicant into the Exec parameter in
/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service).
Similarly, this can be used to use another driver wrapper with
NetworkManager (e.g., -onl80211 to replace WEXT with nl80211).

76d11d3f42 SME: Improve processing of association rejection
Force deauthentication from the AP to clear mac80211 state (it would get
stuck with future scans if the AP is left in authenticated, but not
associated, state).

Add blacklist entry for the AP to allow other APs with worse signal
strength to be tried (e.g., when APs are trying to do load balancing
with status code 17). Reduce wait for the next scan to speed up
connection in cases where there could be other APs that could accept
association, but which show worse signal strength.

e81634cd18 Skip networks without known SSID when selecting the BSS
Previously, APs that were hiding SSID (zero-length SSID IE in
Beacon frames) could have been selected when wildcard SSID matching
was used. This would result in failed association attempt since
the client does not know the correct SSID. This can slow down WPS
which is often using wildcard SSID matching.

Ignore BSSes without known SSID in the scan results when selecting
which BSS to use.

6d6f4bb87f nl80211: Work around mac80211 limitation on (re)auth when authenticated
mac80211 does not currently allow (re)authentication when we are already
authenticated. In order to work around this, force deauthentication if
nl80211 authentication command fails with EALREADY. Unfortunately, the
workaround code in driver_nl80211.c alone is not enough since the
following disconnection event would clear wpa_supplicant authentication
state. To handle this, add some code to restore authentication state
when using userspace SME.

This workaround will hopefully become unnecessary in some point should
mac80211 start accepting new authentication requests even when in
authenticated state.

b55aaa5fdf Allow IBSS/AP mode networks to be created in ap_scan=1 mode
If no BSSes/IBSSes matching the enabled networks are found in the scan
results, IBSS/AP mode network (if configured) can be created in
ap_scan=1 mode instead of requiring ap_scan=2 mode to be used whenever
using IBSS or AP mode.

289ffc2b61 Add preliminary version of NSS TLS/crypto wrapper for wpa_supplicant
This brings in the first step in adding support for using NSS
(Mozilla Network Security Services) as the crypto and TLS library
with wpa_supplicant. This version is able to run through EAP-PEAP
and EAP-TTLS authentication, but does not yet implement any
certificate/private key configuration. In addition, this does not
implement proper key fetching functions either, so the end result
is not really of much use in real world yet.

0194fedb46 driver_nl80211: Fix MLME key settings for static WEP
Current wpa_supplicant has a bug with WEP keys, it adds a zero-length
sequence counter field to netlink which the kernel doesn't accept.

Additionally, the kernel API slightly changed to accept keys only when
connected, so we need to send it the keys after that. For that to work
with shared key authentication, we also include the default WEP TX key
in the authentication command.

To upload the keys properly _after_ associating, add a new flag
WPA_DRIVER_FLAGS_SET_KEYS_AFTER_ASSOC_DONE indicating that the driver
needs the keys at that point and not earlier.

60b94c9819 Add preliminary background scan and roaming module design
This allows background scanning and roaming decisions to be contained in
a single place based on a defined set of notification events which will
hopefully make it easier to experiment with roaming improvements. In
addition, this allows multiple intra-ESS roaming policies to be used
(each network configuration block can configure its own bgscan module).

The beacon loss and signal strength notifications are implemented for
the bgscan API, but the actual events are not yet available from the
driver.

The included sample bgscan module ("simple") is an example of what can
be done with the new bgscan mechanism. It requests periodic background
scans when the device remains associated with an ESS and has couple of
notes on what a more advanced bgscan module could do to optimize
background scanning and roaming. The periodic scans will cause the scan
result handler to pick a better AP if one becomes available. This bgscan
module can be taken into use by adding bgscan="simple" (or
bgscan="simple:<bgscan interval in seconds>") into the network
configuration block.

3180d7a208 Getting back to DISCONNECTED afer SCANNING
After transitioning from DISCONNECTED to SCANNING, we never go back
to DISCONNECTED even though scanning is done or failed.
We're thus stuck in SCANNING while scanning is actually done.

Convert wpa_supplicant_get_scan_results_old() to use the same return
style with the other get_scan_results options and clean up the code
by sharing the same scan result freeing and error checking code for
all the options.
