7756114f6a Postpone global_init() call until first driver instance is initialized
This avoids allocating global driver state for driver wrappers that
are built in but not used. This can save some resources and avoids
failures with driver_nl80211.c that is now initializing netlink
connections for nl80211 in global_init().

17fbb751e1 Remove user space client MLME
This code was used only with driver_test.c to allow MLME operations
in hostapd to be tested without having to use a real radio. There
are no plans on extending this to any other use than testing and
mac80211_hwsim has now obsoled the need for this type of testing.
As such, we can drop this code from wpa_supplicant to clean up the
implementation of unnecessary complexity.

6a90053cdf Add delayed scheduled scan request
When initializing, the scheduled scan code was being called before
everything is ready. With normal scans, the first scan round is
delayed, so the initialization is finished by the time it really
starts.

Add a function that can be used to request a delayed scheduled scan.
The scan will only start after the specified time has elapsed. Call
this function instead of starting the scheduled scan directly during
driver initialization.

b59e6f267b Add filter support to scheduled scans
Pass SSIDs to be matched in scheduled scan results. Only the SSIDs
that are included in the match lists will be reported by the driver,
so the filtering can be offloaded to the hardware and the power
consumption can be reduced.

cbdf3507e9 Add scheduled scan driver operations
In new Linux kernel versions (>=3.0), nl80211 adds scheduled scan
capability. In order to use this feature to its full extent, we need
to support it in the wpa_supplicant core, so that it can also be used
by other drivers.

This commit adds initial scheduled scan support operations and events.

04ea7b7947 GAS: Add a generic GAS query module
This implements GAS request mechanism that is aimed at being used to
replace use case specific GAS/ANQP implementations in the future.
Compared to the earlier implementation in P2P SD, this implementation
includes support for multiple concurrent requests and more thorough
validation of frames against the pending query data.

GAS header processing, including comeback and reassembly, are handled
within gas_query.c and the users of this module will only need to
provide the Query Request and process the (possibly reassembled)
Query Response.

0096c42740 Do not enable bgscan when driver takes care of BSS selection
There is no need to request periodic bgscans when the driver claims
to have capability for roaming within ESS. Ignoring the bgscan

with drivers the handle roaming and with drivers that don't.

22628eca34 Support driver-based BSS selection in ap_scan=1 mode
If the driver indicates that it supports BSS selection (including
roaming within an ESS) with WPA_DRIVER_FLAGS_BSS_SELECTION, modify
ap_scan=1 mode to behave like ap_scan=2 mode for BSS selection.

The initial scan is still done to avoid the need for strict
configuration of or security parameters (e.g., to figure out whether
TKIP or CCMP is being used as the group cipher). However, when
requesting the driver to connect, the bssid and freq parameters are
not provided to leave the driver in control of selecting which BSS
to use and to allow the driver to decide when to roam.

If a network configuration block is removed or modified, flush
all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).

The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the
PMKSA cache flushing, so it does not need a separate mechanism
for clearing the network_ctx values in the PMKSA cache.

70f8cc8ec8 Share the same enum for MFP configuration
The three existing enums were already depending on using the same
values in couple of places and it is just simpler to standardize on
one of these to avoid need for mapping between different enums for
the exact same thing.

9ba9fa07cc Move wpa_supplicant specific scan code away from src/drivers
This fits better in wpa_supplicant/scan.c. Couple of remaining
scan_helpers.c functions are currently used in driver wrappers,
but they can likely be removed in the future.

245519e0cd Replace wpa_supplicant_sta_rx() call with driver event
Get rid of wpa_supplicant_sta_rx() and add a new driver event that is
marked to be used only with driver_test.c. In addition, remove this
functionality from privsep wrapper. This is only use for client mode
MLME testing with driver_test.c.

8d923a4acf Only expire scanned BSSes based on new scan results
Get more information about scans when updating BSS table information.
This allows the missing-from-scans expiration rule to work properly
when only partial set of channels or SSIDs are being scanned.

8e56d18993 dbus: Fix D-Bus network and BSS object registration/unregistration
Do not try to unregister BSS objects twice (the latter one with invalid
path) and make sure all network objects get added and removed properly
(the ones read from configuration file were not being registered, but
were tried to be unregistered).

34359a3fb1 Include BSS table unconditionally in the wpa_supplicant build
This will allow more cleanup to be done for scan results processing
since all code can now be made to depend on the BSS table instead of
the temporary scan results.

Once remaining code has been converted to use the BSS table, the new
scan results can be freed immediately after the BSS table has been
updated. In addition, filtering of BSS information should be added
to better support systems with limited resources. For now, memory
use can be limited by defining WPA_BSS_MAX_COUNT to be smaller.
Anyway, better filtering of results to only the configured networks
should be added to improve this.

83922c2d34 Add BSS table to track scan results without dropping information
Collect information from scan results into a BSS table that will not
expire information as quickly as scan results where every new scan,
no matter for how limited set of channels/SSIDs, clears all old
information.

For now, this is only used for D-Bus BSS added/removed notifications,
but this will likely be extended to be used internally instead of the
scan results to better support partial scans.

Instead of forcefully deinitializing ER immediately, give it some

ER code has completed its work.

c302f20740 Initialize new_connection = 1 to fix wpa_supplicant AP mode operstate
When setting up an AP with wpa_supplicant, the initial connection was
not necessarily setting oper state from DORMANT to UP which would be
blocking normal data frames. Fix this by initializing new_connection
to 1 so that even the first change to COMPLETED state will end up
setting oper state.

9c972abb66 IBSS RSN: Wait for connection event and do not use auth timeout
Wait for connection (IBSS join completed) event before marking state
completed. In addition, do not use the station mode authentication
timeout since that can trigger full disconnection from IBSS when
there is a timeout with just one of the peers.
