14dc00115e dbus: Add "excessive" to debug_strings
The "debug_strings" private array in dbus_new_handles.c has fallen out
of sync with wpa_debug.h. Add the new "excessive" level to the head of
the list, realigning everything.

78633c3709 wpa_supplicant: Parameterize BSS table expiration age + count
Replace compile-time BSS cache expiration age and scan count by config
parameters that can be set via wpa_cli and the new D-Bus API. The latter
is done with interface properties BSSExpireAge and BSSExpireCount.

7c49fdd0bd dbus: Add RemoveAllNetworks to the new D-Bus API
This adds a new command to the interface to remove all configured
netblocks. Without this it's necessary to query properties on the
interface and explicitly remove each netblock.

2b65b30da8 dbus: Add D-Bus methods to flush the BSS cache
Add an "Interface.FlushBSS" method to the new D-Bus API and a "flush"
method to the old API. Both take an age parameter that is a threshold
(in seconds) for selecting entries to evict. Setting this parameter
to zero flushes all entries from the cache.

This mechanism is useful for a connection manager to clear state at
startup and on resume (where the age parameter may be used to hold
onto recent/valid data).

d4c1ec56f1 dbus: Add ConfigFile to AddInterface properties
This provides feature parity with the old-style D-Bus API. Explicit
properties to control global parameters is preferred but until that
happens this allows doing things like setting pkcs11_engine_path and
pkcs11_module_path via D-Bus.

5b49c9d5ed dbus: Fix interface list getter with multiple interfaces
There's a bug in the getter for the 'Interfaces' property
of /fi/w1/wpa_supplicant1 (new D-Bus interface) which causes a
'Segmentation Fault' when there are multiple interfaces.

8e5f078fb9 dbus_new_handlers: Omit errant dbus_message_unref
This unref is guaranteed to be freeing a NULL pointer.

Tested manually: use dbus-send to send an invalid debug level parameter

Before change:

$ dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:msgdumpf
Error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply
(timeout by message bus)
(and then wpa_supplicant crashes)

After change:

$ dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:msgdumpf
Error fi.w1.wpa_supplicant1.InvalidArgs: Did not receive correct message
arguments.

8ee69e0633 dbus_new_handlers: Don't send NULL to dbus_message_new_error
The new DBus API helper function wpas_dbus_error_unknown_error
function can be called as a result of a failure within internal
getter calls, which will call this function with a NULL message
parameter.  However, dbus_message_new_error looks very unkindly
(i.e, abort()) on a NULL message, so in this case, we should not
call it.

I've observed this course of events during a call to
wpas_dbus_getter_bss_wpa with a faileld parse of the IE parameter.
We got here through a call to fill_dict_with_properties which
explicitly calls getters with a NULL message parameter.  Judging
from the way it is called, this could easily occur if an AP sends
out a malformed (or mis-received) probe response.  I usually run
into this problem while driving through San Francisco, so I'm
exposed to any number of base stations along this path.

556522ee09 dbus: Treat '' in SSIDs of Interface.Scan as a request for broadcast scan
This patch changes wpa_supplicant policy for handling '' in SSIDs field of
Interface.SSID DBus message. It treats '' (zero-length) SSID as a request
for a broadcast scan, instead of ignoring it.

This patch updates DBus API .Scan() logic per the test cases listed below:

1) Interface.Scan({'Type':'active', 'Channel':(2412, 20)})
   Request:     Active scan with only '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest on specified channel
   Previous:    1 broadcast ProbeRequest on specified channel
   This Patch:  1 broadcast ProbeRequest on specified channel

2) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['']})
   Request:     Active scan with only '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest on specified channel
   Previous:    No ProbeRequests; passive scan results for specified channel
   This Patch:  FIXED: 1 broadcast ProbeRequest on specified channel

3) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['MySSID']})
   Request:     Active scan with only non-'' SSIDs (1 channel)
   Should be:   1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest
   Previous:    1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest
   This Patch:  1 directed ProbeRequest for each SSID on specified channel,
	no broadcast ProbeRequest

4) Interface.Scan({'Type':'active', 'Channel':(2412, 20), 'SSIDs':['',
	'MySSID']})
   Request:     Active scan with SSIDs, including 1 '' SSID (1 channel)
   Should be:   1 broadcast ProbeRequest, 1 directed ProbeRequest for each
	non-'' SSID on specified channel
   Previous:    1 directed ProbeRequest for each non-'' SSID on specified
	channel
   This Patch:  FIXED: 1 broadcast ProbeRequest, 1 directed ProbeRequest for
	each non-'' SSID on specified channel

a7af023b84 dbus: Fix passive/active scans in some cases
Currently the DBus Interface.Scan API is counter-intuitive. It issues
ProbeRequests when doing passive scans when channels are specified, and
does not issue ProbeRequests for broadcast active scans.

This patch updates DBus API .Scan() logic per the test cases listed below:

 1) Interface.Scan({'Type':'passive'})
    Request:     Passive scan (all channels)
    Should be:   No ProbeRequests; Passive Scan results for all channels
    Previous:    1 ProbeRequest on all channels for both broadcast SSID and
	selected network (scan_ssid=1)
    This Patch:  --No change--: 1 ProbeRequest on all channels for both
	broadcast SSID and selected network (scan_ssid=1)

 2) Interface.Scan({'Type':'passive', 'Channel':(2412, 20)})
    Request:     Passive scan (1 channel)
    Should be:   No ProbeRequests; Passive Scan results for 1 channel
	(plus overlapping channels)
    Previous:    1 broadcast ProbeRequest on specified channel
    This Patch:  --Fixed--: No ProbeRequests; Passive Scan results for 1
	channel (plus overlapping channels)

 3) Interface.Scan({'Type':'active'})
    Request:     Active scan with no SSIDs (all channels)
    Should be:   1 broadcast ProbeRequest on all channels
    Previous:    No ProbeRequests;  passive scan results for all channels
    This Patch:  --Fixed--: 1 broadcast ProbeRequest on all channels

 4) Interface.Scan({'Type':'active', 'Channel':(2412, 20)})
    Request:     Active scan with no SSIDs (1 channel)
    Should be:   1 broadcast ProbeRequest on specified channel
    Previous:    No ProbeRequests; Passive scan results for specified
	channel (plus overlapping channels)
    This Patch:  --Fixed--: 1 broadcast ProbeRequest on specified channel

f9cd8587fb dbus: Deauthenticate instead of disassociate on disconnect command
This clears up authentication state in the driver and in case of
cfg80211, unlocks the BSS entry for the previously used AP. The
previous commit cf4783e35f changed
only the ctrl_iface DISCONNECT command behavior; this new commit
does the same for D-Bus commands.

7cc5995845 Skip D-Bus signals if the dbus_path is not yet set
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.

e30020c7ab dbus: Fix flush_object_timeout_handler context to be consistent
The path pointer used as the timeout_ctx was not constant; the path
string itself may have been the same, but the pointer certainly was not
since it was sometimes from stack and sometimes from the dynamically
allocated buffer in obj_desc. This caused some of the eloop timeout
cancellations not to find the timeout. Fix this by using the obj_desc
as the timeout context data.

abd7a4e353 dbus: Aggregate PropertiesChanged signals
Instead of sending PropertiesChanged signals for each changed
property separately, mark properties as changed and send aggregated
PropertiesChanged signals for each interface in each object.
Aggregated PropertiesChanged signal is sent
- for all object after responding on DBus call
- for specified object after manual call to
  wpa_dbus_flush_object_changed_properties() function
- for each object separately after short timeout (currently 5 ms)
  which starts when first property in object is marked changed

27f43d8de5 dbus: Replace StateChanged with PropertiesChanged signal
The actual supplicant state is exposed via a property on the interface
object. So having a separate signal StateChanged for notifying about
changes is a bad idea. The standard PropertiesChanged signal should be
used for this.

The advantage of StateChanged signal was that it includes the previous
state, but not even NetworkManager is making use of this. And tracking
the old state via the property and this signal is easily possible anyway.
