dc01de8a0e nl80211: Fix TDLS key configuration to not set TX key index
The nl80211 command for setting the TX index does not distinguish TDLS
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
TDLS key.

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.

Since the P2P_DEVICE support indication was added to kernel before

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

a0133ee1c9 nl80211: Make use of driver's capability to detect inactive stations
When drivers advertise their capability to free up inactive
stations based on ap_max_inactivity, send the inactivity period
timeout to driver in NL80211_ATTR_INACTIVITY_TIMEOUT. This
introduces a WPA_DRIVER_FLAGS (WPA_DRIVER_FLAGS_INACTIVITY_TIMER)
so that the inactivity period will be sent only when this capability
bit is set.

e1bd4e1934 nl80211: Fix deauth/disassoc for AP mode SME-in-driver case
When the driver (or firmware) implements AP mode SME, the use of raw
management frame TX functions is not working properly at the moment. As
an initial step, convert these AP mode operations to use
NL80211_CMD_DEL_STATION and do not claim that driver provides TX status
for deauth/disassoc frames. While this does not address all use cases
(e.g., reason code is not specified in the command), this fixes number
of issues where the station does not get disconnected properly.

d1f4942ba1 nl80211: Filter unexpected interface added/up events
It looks like a RTM_NEWLINK event claiming the interface to be UP is
delivered just before removing an interface after having first indicated
that the interface was going down/removed. Ignore this event if the
interface is not present anymore at the moment the event is processed.
This fixes issues where an interface that was re-added after being
removed did not get reconfigured properly.

MCS Rates can be disabled to force to slower speeds when using HT.
Rates cannot be forced higher.

HT can be disabled, forcing an 802.11a/b/g/n station to act like
an 802.11a/b/g station.

HT40 can be disabled.

MAX A-MSDU can be disabled.
A-MPDU Factor and A-MPDU Density can be modified.

Please note that these are suggestions to the kernel. Only mac80211
drivers will work at all. The A-MPDU Factor can only be decreased and
the A-MPDU Density can only be increased currently.

a7a6af4cba nl80211: Derive frequency for BSSes other than the first
Commit e4fb216769 moved frequency
storage from driver struct to bss struct and is assigned in
wpa_driver_nl80211_set_freq. As this wpa_driver_nl80211_set_freq is
triggered only on the first_bss, bss->freq for other BSSes is never
being set to the correct value. This sends MLME frames on frequency zero
(initialized value of freq) for BSSes other than the first.

To fix this derive frequency value from first_bss.

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.

b9fd8ce804 nl80211: Fix NL80211_CMD_FRAME to not try offchannel without driver support
The offchanok parameter is hardcoded to one in number of paths and that
added NL80211_ATTR_OFFCHANNEL_TX_OK attribute to NL80211_CMD_FRAME
unconditional. cfg80211 rejects this with EINVAL if the driver does not
indicate support for offchannel TX. Fix this by not requesting
offchannel TX depending on driver capabilities. Remain-on-channel
operation was used for those cases anyway, so the additional attribute
was not really needed for these in the first place.

When nl80211_setup_ap() has enabled Probe Request reporting, this must
not be disabled when P2P Listen state is stopped to avoid breaking AP
mode operations. This could happen, e.g., if a Probe Request frame was
received from a P2P device that the we are trying to invite to our group
(i.e., when operating in GO role). p2p_probe_req_rx() calls
p2p_invite_start() in this case and that ends up calling
p2p->cfg->stop_listen() which calls probe_req_report() driver op.
