a1641d2671 Call wpas_notify_network_selected only if a specific network was selected
ssid could be NULL here at least based on the function documentation,
so better check whether that is the case prior to calling the
notification function.

5be45e2e6e Fix per-SSID scan (scan_ssid=1)
Commit d3a9822542 broke per-SSID scan
by using the ssid variable for internal loop and by doing so,
overriding the value that was needed below to figure out whether the
scan is for a specific SSID. Fix this by using a temporary variable
instead when looping over network finding which frequencies to scan for.

ea20a1ad03 dbus: Remove unneeded typecast
This was triggering some gcc versions to warn about strict aliasing.
Since the typecast is not really needed here, the cleanest way to get
rid of the warnings is to just use the correct type for the local
variable.

69856fadf7 Add wpa_msg_ctrl() for ctrl_interface-only messages
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)

b905c4a398 WPS: Add HTTP server module
Clean up code so that UPnP implementation does not need to include all
the HTTP functionality. In addition, make it easier to share HTTP server

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.

dc461de43e wpa_supplicant and dbus code separation
This patch completely separates supplicant's code from dbus.
It introduces three new notifications which copes with all
remaining dbus stuff.
wpas_notify_unregister_interface() was renamed to
wpas_notify_iface_removed().

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.

f042122a57 Allow the internal DH implementation to be overridden
Crypto library wrappers can now override the internal DH (group 5)
implementation. As a starting point, this is done with OpenSSL. The
new mechanism is currently available only for WPS (i.e., IKEv2 still
depends on the internal DH implementation).

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.
