d6dcfcdaac nl80211: Add a handler to create_interface
Add an option to pass a handler to nl80211_create_iface() and
nl80211_create_interface_once() that will be called after receiving the
message from the kernel. This handler will add the option to process the
message in different ways for different interfaces.

d3aaef8034 nl80211: Hold wdev identification for P2P Device
Add wdev_id to i802_bss. wdev_id_set indicates whether this id is
available. Use wdev_id if assigned, instead of ifindex. Use wdev_id for
events that come from the kernel to identify the relevant interface.
This commit does not assign wdev_id value for the BSS yet, i.e., this is
only preparation for the value to be used in a future commit.

add9b7a46a nl80211: Ignore deauth/disassoc event from old AP
It looks like cfg80211 can deliver a deauth/disassoc event during some
roaming cases while we are already in progress with a new
authentication/association. This happens at least with FT protocol.
Avoid issues with such disconnection event resulting in core
wpa_supplicant stopping the new connection attempt by tracking
auth/assoc BSSID more carefully within driver_nl80211.c and filtering
out events that do not apply for the current AP.

455299fb40 nl80211: Fix foreign address filtering for MLME frame events
Commit 97279d8d1a started filtering MLME
frame events based on Address 1 (destination) field. This works fine for
frames sent to us, but it did filter out some corner cases where we
actually want to process an event based on a frame sent by us. The main
such case is deauthentication or disassociation triggered by something
external to wpa_supplicant in the system. Fix this by accepting events
for frames where either Address 1 or 2 (transmitter) matches the
interface address.

708bc8e0e4 nl80211: Restore previous nlmode if set_freq for AP mode fails
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.

3dfd0484fc P2P: Consider age for the P2P scan results
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.

a5e1eb2092 nl80211: Run TKIP countermeasures in correct hostapd_data context
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.

a8c5b43ad3 nl80211: Roam correctly through cfg80211 without SME
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

configuration, but a different cipher suite and somewhat different rules

pairwise/group configuration is needed to enable it. This may change in

CCMP could have been used.

24b5bd8b42 nl80211: Use safe list iteration
In certain cases like PBC session overlap it appears to be possible that
an interface is removed due to an event handled on it, this leads to
list corruption. Use safe iteration to prevent this issue.

b5671498bf nl80211: Use wait_time with AP mode driver SME for offchannel
When sending an offchannel frame (mainly, P2P Invitation Request), the
wait_time parameter was hardcoded to 0 for drivers that implement AP
mode SME. This is not correct and can cause problems for drivers that
support offloading of off-channel operations with driver/firmware based
AP SME.

3bc462cb88 P2P: Add option for Provision Discovery before GO Negotiation
This is a workaround for interoperability issues with some deployed P2P
implementations that require a Provision Discovery exchange to be used
before GO Negotiation. The new provdisc parameter for the p2p_connect
command can be used to request this behavior without having to run a
separate p2p_prov_disc command.

this purpose. Do not accept WEP key length 16 for nl80211 driver

23c84252a4 P2P: Add option to force SSID/passphrase for GO Negotiation
An existing persistent group information can now be used to force GO
Negotiation to use the previously used SSID/passphrase from a persistent
group if we become a GO. This can be used as an alternative to inviting
a new P2P peer to join the group (i.e., use GO Negotiation with GO
intent 15 instead of starting an autonomous GO and using invitation),
e.g., in case a GO Negotiation Request is received from a peer while we
are not running as a GO. The persistent group to use for parameters is
indicated with persistent=<network id> parameter to p2p_connect.

2e9f078c8d nl80211: Indicate disconnect event as deauthentication
This was previously indicated as disassociation, but the P2P group
session ending case expect a deauthentication notification. Since the
cfg80211 disconnection event does not really indicate which frame was
used, the easiest approach for now seems to be to just indicate these
as deauthentication events.

3c29244eb7 P2P: Add deinit_p2p_cli op to clear P2P client driver state
On P2P group removal, the GO is deinitialized correctly (and the vif
mode is set back to sta in case of nl80211), but the P2P client mode
wasn't deinitialized, and the nl80211 vif stays in P2P client mode.

Add a new deinit_p2p_cli op (similar to deinit_ap), which currently only
sets the interface back to station mode.

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.
