a771c07dfc Add driver status information to control interface
STATUS-DRIVER command can now be used to fetch driver interface status
information. This is mainly for exporting low-level driver interface
information for debug purposes.

f78f278520 nl80211: Fix off-channel Action frame TX from GO with use_monitor
TX frequency gets lost when going through the monitor send MLME option
and this resulted in P2P operations like invitation from a GO failing
when the driver needs monitor socket, but would support offchannel TX.
Fix this by using frame_cmd path instead in case the monitor socket
would have been hit for action frame TX.

5d4c78fb1f nl80211: Reset nlmode to station on leaving IBSS
Previously, IBSS mode (NL80211_IFTYPE_ADHOC) was left in drv->nlmode
when leaving IBSS. This causes issues for send_mlme() handler for P2P
Probe Response transmission in Listen state. Fix this by clearing nlmode
back to NL80211_IFTYPE_STATION on leaving IBSS so that following P2P
operations can be executed correctly. Previously, this was fixed only
when the next authentication/association attempt in station mode
occured.

50f4f2a066 hostapd: Add Automatic Channel Selection (ACS) support
This adds ACS support to hostapd. Currently only survey-based
algorithm is available.

To use ACS you need to enable CONFIG_ACS=y in .config and use
channel=0 (or channel=acs_survey) in hostapd.conf.

For more details see wiki page [1] or comments in src/ap/acs.c.

ba873bdf86 wired: Wait for the link to become active before sending packets
Interfaces that take one or two seconds to reconfigure the link after we
set IFF_ALLMULTI or after we bring the interface up were dropping the

60b13c2017 nl80211: Do not change type to station on P2P interfaces
It is possible that when trying to remove a dynamically added interface,
changing its type to station mode is not possible (since the kernel does
not support so in its interface combinations).

Since P2P interfaces are always dynamically added, avoid changing their
type to station in the deinit_ap() and deinit_p2p_client() nl80211
callbacks, assuming that the interface is about to be removed.

wpa_driver_nl80211_set_mode() call. This is not enough to unregister the

drv->assoc_freq was not updated during the connect command (neither
during the command's invocation nor after getting the event) unlike with
auth/assoc case where assoc_freq is updated. This resulted in
nl80211_get_link_noise() (and any other function for that matter) using

API. Fix this by updating drv->assoc_freq on connect command and when

7239ea7f01 nl80211: Add stop AP mode event API
Stop AP command can be used by the driver as an event to indicate that
AP mode has stopped operation. WLAN driver may have encountered errors
that has forced the driver to report this event or concurrent operations
on virtual interfaces may have forced AP operation to be stopped. When
in P2P GO mode, wpa_supplicant uses this event to remove P2P group to
keep in sync with the driver state.

dc01de8a0e nl80211: Fix TDLS key configuration to not set TX key index

vs. AP key and as such, the driver would not know what this set TX key
index operation is doing in the TDLS case. This could result in the TX
key index for AP being changed instead if static WEP is used in the AP
connection. Fix the issue by not setting TX key index when configuring a

3f53c006c7 nl80211: Ignore disconnect event in case of locally generated request
Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.

This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same
behavior.
