54a800dd51 netlink: Fix RTM_SETLINK padding at the end of the message
While the kernel seems to have accepted the message to set linkmode and
operstate without the final attribute getting padded to 32-bit length,
it is better to get this cleaned up to match expected format. The double
NLMSG_ALIGN() followed by RTA_LENGTH() did not make much sense here.

01b3bbfc66 test: Remove driver_test.c
The driver_test.c driver wrapper (-Dtest in wpa_supplicant and
driver=test in hostapd) was previously used for testing without real
Wi-Fi hardware. mac80211_hwsim-based tests have practically replaced all
these needs and there has been no improvements or use for driver_test.c
in a long while. Because of this, there has not really been any effort
to maintain this older test tool and no justification to change this
either. Remove the obsoleted test mechanism to clean up the repository.

3e0272ca00 nl80211: Re-read MAC address on RTM_NEWLINK
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.

b497a21267 nl80211: Ignore auth/assoc events when testing driver-SME
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.

d1bb7aeda4 nl80211: Fix non-hostapd interface addition to not call add_ifidx()
Commit b36935be1a ('nl80211: Fix EAPOL
frames not being delivered') and commit
147848ec4d ('nl80211: Do not add all
virtual interfaces to drv->if_indices') were not fully in sync and it
was possible for some non-hostapd use cases to end up adding undesired
ifindexes into the list of interfaces from which events and EAPOL frames
are processed on the parent interface. This could result, e.g., in P2P
Device management interface on getting unexpected events, including
RTM_NEWLINK event that could end up getting interpreted as an
indication of the interface being down and unavailable.

Make both add_ifidx() calls use the same criteria for adding interfaces
to the local list. This is not really a complete solution, but it is
good enough for now to fix the most visible side effects of this issue.

d3d048310c nl80211: Work around error case prints for nl_recvmsgs on Android
I got the below prints on a particular Android platform:

I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20

In JellyBean libnl_2 code, I see that the nl_recvmsgs returns postive values
too. In some cases, nl_recvmgs return the output of nl_recv function. nl_recv
function can return Number of bytes read, 0 or a negative error code.

Looks like this positive return value for nl_recvmsgs may be specific to
Android. While this is not how the API is supposed to work, this does no
harm with upstream libnl which returns only 0 or -1 from the function.

147848ec4d nl80211: Do not add all virtual interfaces to drv->if_indices
Commit 04eff7d5ba or something around that
timeframe may have caused a regression on how drv->if_indices gets used
with wpa_supplicant. Most (curretly likely all) wpa_supplicant virtual
interface use cases should not actually use this. This could result in
issues with P2P group interfaces delivering events to incorrect
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.

Filter add_ifidx() uses based on hostapd vs. wpa_supplicant and iftype
to get closer to the earlier wpa_supplicant behavior for the driver
events from virtual interfaces.

de88430311 nl80211: Fix del_ifidx() with mixed parent interface cases
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.

1b5df9e591 nl80211: Do not indicate scan started event on scan_for_auth
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

1d91f504e4 hostapd: Process management frames only once per BSS
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.

For example, the optimization option will always be used for cfg80211

without the knowledge of wpa_supplicant/hostapd).

ff5e1d14af nl80211: Treat RSSI as part of each sched scan matchset
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.

If a P2P GO is operating on a channel that the driver recommended not to

restart it on another channel. As a TODO item, this could also be changed

Currently these three steps runs for each event.
1. get buffer size via system
2. allocate a memory for event
3. free the memory

The wpa_supplicant receives 4 events from boot to be connected.
So this patch prepare the event buffer at the init process.

I have tested wpa_supplicant on NetBSD 6.1.2.
But I could not tested hostapd because I do not have AP enabled device.

949938aadf Ask driver to report only new scan results if requested
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
wpa_supplicant.

If Action frame registration in nl80211_mgmt_subscribe_non_ap() failed

none of the Action frame types could be received and even worse, the
