de93da914f tests: Verify double DISABLE on hostapd with multi-BSS configuration
This used to result in a segmentation fault due to use of freed memory
(mismatch in pointer lifetime between hostapd.c and driver_nl80211.c).

d92bdf9602 hostapd: Make sure hapd->drv_priv gets cleared on driver deinit
Couple of code paths in hostapd.c could have left hapd->drv_priv
pointing to memory that was freed in driver_nl80211.c when a secondary
BSS interface is removed. This could result in use of freed memory and
segfault when the next driver operation (likely during interface
deinit/removal). Fix this by clearing hapd->drv_priv when there is
reason to believe that the old value is not valid within the driver
wrapper anymore.

ac1a224092 hostapd: Clean up if interface setup fails
If for some reason interface setup fails mid-way when setting up
multi-BSS AP it was possible to get segmentation fault because driver
was not properly cleaned up.

One possible trigger, when using nl80211 driver, was udev renaming an
interface created by hostapd causing, e.g., linux_set_iface_flags() to
fail.

bedb6ea54f tests: Verify auto_interworking=1 with partiall matching network
This is a regression test for an issue where scanning sequence could be
terminated if interworking_find_network_match() finds a matching
network, but wpa_s->auto_select is not set. This could stop connection
attempts when auto_interworking=1 is used and the scan results have a
partially matching network and no cred match.

b77aeae732 Interworking: Re-trigger scan if no connect attempt is done
For one specific case when running with Interworking enabled the
re-initialisation of the scan timer is missing. This makes auto connect
to a configured network fail.

The case is:
- Interworking credentials available, but do not match
- Auto interworking is enabled (auto_interworking=1)
- Interworking auto select is disabled (i.e., this is from
  auto_interworking=1, not from INTERWORKING_SELECT auto)
- No configured (enabled and non blacklisted) networks are present
  in scan results list with full match
- Interworking finds matching networks (it does not do full security
  policy match)

This patch covers the case and re-initialises the scan timer to allow
search for a suitable network to continue.

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.
