This was done in handle_assoc_cb() in ieee802_11.c for drivers that use
hostapd SME/MLME. However, drivers that include SME/MLME implementation
do not use that function and the STA flag needs to be set when
processing the association notification. This is needed to get the STA
entry into showing the proper authorized state and to get the
AP-STA-CONNECTED/DISCONNECTED events on the control interface.

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).

If hapd_iface->bss[i] == NULL, this could have resulted in NULL pointer
dereference in the debug print. Avoid this by skipping the message in
case of NULL pointer. In addition, clear iface->bss[i] to NULL for
additional robustness even though this array gets freed immediately.

Before this patch, 1 second timeout was used for regulatory updates. In
some cases, specially when we reload driver modules on some slower
platforms this could take more than 1 second (about 2 seconds). This is
important specially for DFS case, where we have to have correct DFS
region before we will start CAC. In other case (unknown DFS region), CAC
will fail. 5 seconds should be enough for all cases.

It is possible for the configuration to be temporarily invalid when
adding a new AP through SET commands followed by ENABLE. Avoid this
issue by using less strict validation on SET commands and perform full
configuration validation only on ENABLE. Use cases with configuration
file maintain their previous behavior, i.e., full validation after the
file has been read.

We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

It is possible for additional BSSs to be added while the primary
interface is still in the process of determining channel parameters (HT
co-ex scan, ACS, DFS). Do not enable secondary interfaces in such state
immediately, but instead, wait for the pending operation on the primary
interface to complete. Once that's done, the added extra BSSs will also
be enabled in hostapd_setup_interface_complete().

This reverts parts of commit 390e489c0d
that tried to enable removal of the first BSS. Since that operation is
now forced to remove all BSSs, these changes are not needed. The

for the first BSS since it ends up freeing driver wrapper information
that is needed later when deinitializing the driver wrapper.

If a secondary BSS is removed while it is waiting for the primary BSS to
complete channel setup (e.g., due to HT co-ex scan, ACS, or DFS), the
hostapd_data instance has not yet been initialized. Fix the BSS removal

The changes in commit 5592065850 to allow
any BSS to be removed were a bit too early since there are still number
of areas that use the first BSS as a special case. Especially the
driver_ops API is going to require quite a bit of cleanup before removal
of the first BSS without the other BSSes of the same radio can be done
safely.
For now, force all BSSs to be removed in case the first one is removed.

Limit the calls to eloop_terminate() to happen only for the

If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.

Previously, ENABLE command ended up freeing the hostapd_iface context on
initialization failures, but did not even remove the interface from the
list of available interfaces. This resulted in use of freed memory with
any following operation on the same interface. In addition, removing the
interface on initialization failure does not seem like the best
approach. Fix both of these issues by leaving the interface instance in
memory, but in disabled state so that the configuration can be fixed and
ENABLE used again to enable the interface or REMOVE used to remove the
interface.
