01a025937c WPS: Add support for 60 GHz band
Handling of WPS RF band for 60 GHz was missing. Add it in all relevant
places and also map "AES" as the cipher to GCMP instead of CCMP when
operating on the 60 GHz band.

4a7ce98469 Make IPv6 NA multicast-to-unicast conversion configurable
This can be used with Proxy ARP to allow multicast NAs to be forwarded
to associated STAs using link layer unicast delivery. This used to be
hardcoded to be enabled, but it is now disabled by default and can be
enabled with na_mcast_to_ucast=1. This functionality may not be desired
in all networks and most cases work without it, so the new
default-to-disabled is more appropriate.

a0ad9e8c9e Remove WPA per-VLAN groups when no more stations remain
Previously, struct wpa_group was created when the first station enters
the group and the struct wpa_group was not freed when all station left
the group. This causes a problem because wpa_group will enter
FATAL_FAILURE when a wpa_group is running while the AP_VLAN interface
has already been removed.

Fix this by adding a reference counter to struct wpa_group and free a
group if it is unused.

253103681c FT: Fix WMM TSPEC validation in driver-based AP MLME case
Commit 88b32a99d3 ('FT: Add FT AP support
for drivers that manage MLME internally') added an alternative way of
processing the WMM TSPEC from RIC. However, that change did not seem to
include the same checks for WMM TSPEC element length that were used in
the original implementation for MLME-in-hostapd case. Fix this by
sharing the older implementation of copying the WMM TSPEC from RIC for
both cases.

It looks like the destination buffer for the response is sufficiently
long for the fixed length copy, but it may have been possible to trigger
a read beyond the end of the FTIE by about 50 bytes. Though, that seems
to be within the buffer received for RX buffer in the case that uses
this driver-based AP MLME design for FT.

c8e6beabb6 Remove VLAN interface on STA free
Currently, vlan_remove_dynamic() is only called when the station VLAN ID
is changed (ap_sta_bind_vlan), but not when the station is freed. So
dynamic VLAN interfaces are not removed actually except within 1x
reauthentification VLAN ID change, although most of the code is already
there.

This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta().

It cannot just use sta->vlan_id for this, as this might have been
changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth
fetches from RADIUS cache for WPA-PSK), thus reference counting might
not have been updated. Additionally, reference counting might get wrong
due to old_vlanid = 0 being passed unconditionally, thus increasing the
reference counter multiple times.

So tracking the currently assigned (i.e., dynamic_vlan counter
increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore,
the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and
setting the VLAN for the sta in driver happens unconditionally.

Additionally, vlan->dynamic_vlan is only incremented when it actually
is a dynamic VLAN.

de31fb052c vlan: Ignore multiple NEWLINK messages
hostapd receives NEWLINK messages multiple times and thus does
configuration of the the vlan interface multiple times.

This is not required and leads to the following during cleanup in
test pmksa_cache_preauth_vlan_used:
 1. run-test.py does: brctl delif brvlan1 wlan3.1
 2. hostapd processes NEWLINK and does: brctl addif brvlan1 wlan3.1
 3. run-test.py does: brctl delbr brvlan1
    -> fails as wlan3.1 is still in the bridge

This patch fixes this by ignoring repeated NEWLINK messages.

371205dd0c vlan: Ignore DELLINK on interfaces that exists
When hitting
> Failed to create interface wlan3.1: -23 (Too many open files in system)
> Try to remove and re-create wlan3.1
hostapd deletes the AP_VLAN interface and then recreates it. Thus the
kernel assigns the same ifidx to the new interfaces and sends DELLINK
and NEWLINK mesages.

As the DELLINK messages are processed after the struct hostapd_vlan is
added, hostapd deletes the struct hostapd_vlan entry, deconfigures the
AP_VLAN interface and leaves vlan_newlink nothing to find afterwards.

So this patch makes DELLINK messages to be ignored when the interface
exists.

a5e81ba9eb Fix STA VLAN bind for RSN pre-authentication case
Previously, during RSN preauthentication, ap_sta_bind_vlan() was called,
which fails for non-zero sta->vlan_id as the station is not known to the
kernel driver.

Fix this by binding the station only if it is associated. If it is not
associated, ap_sta_bind_vlan() will be done later during association.

In addition, reject Access-Accept if the returned VLAN ID is not valid
in the current hostapd configuration.
