While these elements fit without issue in production use cases, it is
possible to override the elements for testing purposes and if such
overridden elements are overly long, they would nto fit into the maximum
length RSN Override Link KDE. This could result in difficult to debug
failure cases, so check for this explicitly and instead of sending out
the invalid M3, report the internal issue in the debug log and do not
send M3.

STA needs to skip validating RSN Override elements when RSN overriding

A STA that supports RSN overriding will always use the SNonce cookie. An
AP that does not advertise RSN overriding elements must not enforce that
SNonce cookie is used with RSN Selection element since a STA includes
the latter only when it sees the AP advertising RSN overriding elements.

wpa_auth_get_seqnum() for ML group rekeying needs to be skipped in the
same way as it is done for non-ML cases to avoid indicating old values
and resulting in group frames being dropped as replays. The simple check
for gsm->wpa_group_state != WPA_GROUP_SETKEYS (as is done for non-ML) is
not sufficient for this since the per-link Authenticator states are not
strictly synchronized and the state change happens in the middle of this
step.

In the current hostapd flow, AP_VLAN net device is added to a bridge
before the interface is brought up.
Interface up event is used in mac80211 layer for setting device context
in the driver. Vendor specific datapath offload configurations for net
device might also be set up in interface up event context. Adding
AP_VLAN interface to a bridge before the UP event could cause
inconsistent state for datapath offload context setup in a vendor
driver.
Change the sequence to add AP_VLAN interface to a bridge after the
interface is set up. This makes the interface up and bridge add sequence
for AP_VLAN to be consistent with that of a regular AP interface.

Whenever there is only one BSS left and if the number of links is one,
is_shared_drv() returns false assuming no one else is sharing the driver
interface. However, when the number of links is one, this does not
guarantee that the caller's link ID is the only active link ID. If this
is not the case and false is returned, the caller calls hapd_deinit()
which will free the driver interface. However, when the actual active
link_id reaches deinit path, this leads to dereferencing a NULL pointer
ultimately leading to segmentation fault.
To prevent this, pass the link ID into the is_drv_shared() ops and match
it with only with active link IDs. Only return false if they are same.

In function driver_nl80211_link_remove(), when there is no active links,
interface is removed. This will free the BSS pointer. A copy of the BSS
pointer is also stored in each of the affiliated links' hapd->drv_priv
member.
driver_nl80211_link_remove() is called via multiple paths, e.g., via
NL80211_CMD_STOP_AP and via driver_nl80211_ops. When called when
handling an nl80211 event, links will be removed and when count reaches
zero, the interface will be removed. However, core hostapd will be
unaware of this removal. Hence, if it tries to access its drv_priv
pointer, this can lead to segmentation fault at times since the pointer
is now pointing to freed memory.
Prevent this by adding a new notification event
(EVENT_MLD_INTERFACE_FREED). Whenever the interface is freed, this
notification will be sent. hostapd will process this notification and
will set all affliated links' hapd->drv_priv to NULL.
