This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as

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.

It is possible for unmasking of 11b rates to fail if a P2P group is

could result in the 11b TX rates being left masked for non-P2P

since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case

Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).
This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

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

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.

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the
VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the presence
of the respective IEs in the received TDLS Setup Response frame.
The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

The scan_for_auth workaround for cfg80211 missing a BSS entry for the
target BSS during authentication uses a single channel scan controlled
within driver_nl80211.c. This operation does not indicate
EVENT_SCAN_RESULTS to the upper layer code. However, it did report
EVENT_SCAN_STARTED and this resulted in the radio work protection code
assuming that an external program triggered a scan, but that scan never
completed. This resulted in all new radio work items getting stuck
waiting for this scan to complete.
Fix this by handling the scan_for_auth situation consistently within
driver_nl80211.c by filtering both the EVENT_SCAN_STARTED and
EVENT_SCAN_RESULTS.

If NL80211_CMD_AUTHENTICATE fails due to exiting authentication, forced
deauthentication is used to clear cfg80211 start and a new
authentication command is retried. This resulted in an extra
disconnection event getting delivered to the core wpa_supplicant code
and that could end up confusing state there, e.g., by clearing
connection parameters like wpa_s->key_mgmt and preventing the following
association from reaching proper COMPLETED state with open networks.
Fix this by hiding the unnecessary disconnection event when using the
deauth-for-auth workaround.

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.

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

(NL80211_CMD_*) is encoded as the subcmd and the attributes in the

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

Add a callback to the driver interface that allows vendor specific

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

The original RSSI filter semantics for scheduled scan were
really confusing - a separate matchset was created, but it
wasn't actually treated as a separate matchset in the kernel
but rather used as the global RSSI value. The RSSI matchset
thus behaved like an RSSI filter outside of the matchsets,
being ANDed rather than ORed (as normal between matchsets.)
To make this less confusing, I changed the kernel API a bit
to actually treat the RSSI inside each matchset properly,
but keeping it compatible with the old approach by using a
matchset with only an RSSI value as the default for all the
other matchsets, and adding it as a separate matchset only
if it's the only one.
The proper way for wpa_supplicant to do this then would be
to add the RSSI to each SSID matchset, and only add another
matchset without SSID if there's none with.
However, to keep compatibility with older kernels, always
keep the non-SSID matchset and only add the RSSI to all the
other matchsets. This gets close to the desired behaviour,
the only difference would be that we shouldn't add the RSSI
matchset if there are others, but stays compatible with old
and new kernels, as new ones ignore the RSSI-only matchset
if there are others and those others have an RSSI.

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).
In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can
be used to clear all BSS entries from both the driver and
