65d52fc103 Add capability flag for IBSS and add get_capability modes
Add a driver capability flag for drivers which support IBSS mode and set
it for nl80211 drivers which have set the NL80211_IFTYPE_ADHOC.

Add a new option "modes" to "get_capability" which will return "AP" and
"IBSS" if the corresponding capability flags are set.

The idea is that this can be used for UIs to find out if the driver
supports IBSS mode.

e9ee8dc394 wpa_supplicant: Support VHT capability overrides
Add support for VHT capability overrides to allow testing connections
with a subset of the VHT capabilities that are actually supported by
the device. The only thing that isn't currently supported (by mac80211
and this code) is the RX/TX highest rate field.

c5f10e804a Use more accurate timestamps for scan results
For various P2P use cases, it is useful to have more accurate timestamp
for the peer information update. This commit improves scan result
handling by using a single timestamp that is taken immediately after
fetching the results from the driver and then using that value to
calculate the time when the driver last updated the BSS entry. In
addition, more debug information is added for P2P peer updates to be
able to clearly see how old information is being used here.

3140803b6d nl80211: Add ctrl_iface message for AP mode connection rejection
When AP mode operation reject the client, nl80211 layer advertises the
connect failed event with the reason for failures (for example, max
client reached, etc.) using NL80211_CMD_CONN_FAILED.

This patch adds some debug messages whenever such an event is received
from the nl80211 layer and also the same event is posted to the upper
layer via wpa_msg().

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
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.

8342185012 HS 2.0: Add mechanism for disabling DGAF
disable_dgaf=1 in hostapd.conf can now be used to disable downstream
group-addressed forwarding (DGAF). In this configuration, a unique
GTK (and IGTK) is provided to each STA in the BSS to make sure the
keys do not match and no STA can forge group-addressed frames.

An additional mechanism in the AP needs to be provided to handle some
group-addressed frames, e.g., by converting DHCP packets to unicast
IEEE 802.11 frames regardless of their destination IP address and by
providing Proxy ARP functionality.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.

3d9975d5b0 Do not trigger fast reconnection on locally generated deauth/disassoc
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.

Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.
