When scan failed, the wpa_driver_nl80211_scan method tried
to recursively call itself, but it passed in the wrong argument
for the void*, and so then it crashed accessing bad memory.
With this fix, hostapd still will not retry the scan later, but
at least it will exit cleanly and won't polute the file system
with core files.

This was previously included only with NL80211_CMD_ASSOCIATE, but the
information is as useful (if not even more useful) for
NL80211_CMD_CONNECT. It should be noted that cfg80211 does not yet use
this attribute with NL80211_CMD_CONNECT, but that can be added easily.

wpa_driver_nl80211_ap() returned error if set_freq failed, but left the
previously set nlmode to GO/AP. While this should not be issue for most
purposes, it leaves the interface in somewhat unexpected state and could
potentially affect operations prior to next connection attempt. Address
this by restoring the previous nlmode if AP mode cannot be started for
some reason.

cfg80211 caches the scan results according the channel number. Due to
the 15 sec aging this might cause the user mode to see more than one
scan result with the same BSSID, e.g. - one scan result for the
P2P Device and one for the P2P GO (once it's enabled).
Fix this by updating the device entry only if the new peer entry is
newer than the one previously stored.

hostapd can run with different VIF when using nl80211. Events about MIC
failures have to be processed in context of the VIF which received it
and not in context of the primary VIF. Otherwise the station belonging
to this VIF may not be found in the primary VIF station hash and
therefore no countermeasures are started or the countermeasures are
started for the wrong VIF.

Replace CONFIG_IEEE80211V with CONFIG_WNM to get more consistent build
options for WNM-Sleep Mode operations. Previously it was possible to
define CONFIG_IEEE80211V without CONFIG_WNM which would break the build.
In addition, IEEE 802.11v has been merged into IEEE Std 802.11-2012 and
WNM is a better term to use for this new functionality anyway.

Change the nl80211 driver in wpa_supplicant to correctly handle
connecting to a new AP through cfg80211 without SME capability. As
before, the driver will disconnect from the previously associated AP,
but now we attempt to immediately connect to our intended AP. This
prevents us from blacklisting the AP we were trying to connect to
because of a semantic mismatch between cfg80211 and wpa_supplicant. The
disconnect/connect patch generates a local disconnect nl80211 event
which we discard because we're already correctly tracking the pending
association request.
In detail:
cfg80211 does not support connecting to a new BSS while already
connected to another BSS, if the underlying driver doesn't support
separate authenticate and associate commands. wpa_supplicant is written
to expect that this is a supported operation, except for a little error
handling that disconnects from the current BSS when roaming fails and
relies on autoconnect logic to reconnect later. However, this failure to
connect is incorrectly attributed to the new AP we attempted to
associate with, rather than a local condition in cfg80211.
The combined effect of these two conditions is that full-mac drivers
accessible through cfg80211 but without SME capability take a long time
to roam across BSS's because wpa_supplicant will:
1) Fail to associate for local reasons
2) Disconnect and return that the association request failed
3) Blacklist the association target (incorrectly)
4) Do a scan
5) Pick a less desirable AP to associate with

If the driver indicates support for multi-channel concurrency, change

instead, just mark it as preferred for GO Negotiation. This change

This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.
This commit does not included changes to WPS or P2P to allow GCMP to be
used.

Right now 11b rates are masked out while creating a P2P interface,
but this is always failing as the interface is down. Most drivers
allow to configure rates only when the interface is UP and running.
So let us disable 11b rates when interface type is changed into a
P2P type and it is UP and running.
