This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.
In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not

Commit 5a2a6de6a5 ('mesh: Make inactivity
timer configurable') has a problem on 32 bit systems. Setting
NL80211_MESHCONF_PLINK_TIMEOUT to 0xffffffff causes expiration of STA in
a minute by NL80211_CMD_DEL_STATION event. this is the kernel rule for
STA expiration:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On a 32 bit system, the right side could overflow and be unexpected
small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large. STA
expiration occurs by this reason.
This patch solves the problem by disabling the STA expiration
functionality in mac80211. However, old kernel does not support
disabling it. If so, this patch sets mac80211 inactivity timer 60
seconds into future from the wpa_supplicant inactivity timer.

timer in wpa_supplicant. This commit fixes it also.

Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.
Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.

Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.
Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.

function can return Number of bytes read, 0 or a negative error code.

interface (parent rather than the group interface). The previous commit
removed some of the issues, but more complete fix is to undo some of
those merged hostapd/wpa_supplicant operations.

It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.
This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.
Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.

At least in nl80211, broadcast management frames like Probe Request
frames, may be processed multiple times per BSS if multi-BSS is active
and NL80211_CMD_FRAME event is used to deliver them. In the case of
Probe Request frames, hostapd will create multiple redundant Probe
Response frames which are problematic when many BSS are on one channel.
This problem is caused by driver_nl80211 generating an event for
wpa_supplicant_event() for each BSS, and hostapd_mgmt_rx() calls
ieee802_11_mgmt() for each BSS, too.
Fix this by processing broadcast events only for the BSS the driver
intended to. The behavior is not changed for drivers not setting a BSS.

While these were already available from elsewhere in the debug log, it
is convenient to have the values also available at the location where
the actual nl80211 command is issued.

wpa_supplicant already allowed beacon interval to be configured for AP
mode operations, but this was not passed to the driver for IBSS even
though the same parameter can used for that case. Add this for the
nl80211 driver interface to allow beacon interval to be controlled for
IBSS as well.

This commit adds an option to optimize AP teardown by leaving the
deletion of keys (including group keys) and stations to the driver.
This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.
For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).

CONFIG_TESTING_OPTIONS=y build of wpa_supplicant now allows arbitrary
cfg80211 commands to be performed through the new VENDOR ctrl_iface
command by using a special vendor_id ffffffff. The command identifier
(NL80211_CMD_*) is encoded as the subcmd and the attributes in the
hexformatted data area. Response attributes are returned as a hexdump.
For example, this shows a NL80211_CMD_FRAME and a response (cookie
attribute) on a little endian host:
wpa_cli -i wlan0 vendor ffffffff 59 080003004d0000000800260085090000....

When an interface is disabled through rtm event, wpa_supplicant's
EVENT_INTERFACE_DISABLED is generated, which in turn, may
completely destroy wpa_driver_nl80211_data struct (drv). This
scenario happens now when P2P GO interface is disabled. Since this
struct may be used later in this function it causes segmentation fault.
Fix it by trying to find drv again in the interface list after
wpa_supplicant's event handling.

Add a callback to the driver interface that allows vendor specific
commands to be sent. In addition, a control interface command is added
to expose this new interface outside wpa_supplicant:
Vendor command's format:
VENDOR <vendor id> <sub command id> [<hex formatted data>]
The 3rd argument will be converted to binary data and then passed as
argument to the sub command.
This interface is driver independent, but for now, this is only
implemented for the nl80211 driver interface using the cfg80211 vendor
commands.
