The PMKIDCount, PMKID List, and Group Management Cipher Suite fields are
optional to include in the RSNE in cases where these would not have
values that are different from the default values. In practice,
PMKIDCount is always 0 in Beacon and Probe Response frames, so the only
field of these that could have a non-default value is Group Management
Cipher Suite. When BIP is used, that field is not needed either due to
BIP being the default cipher when PMF is enabled.
Remove these fields from RSNE when BIP is used to save six octets in
Beacon and Probe Response frames. In addition to reduced frame length,
this is a workaround for interoperability issues with iOS 8.4 in cases
where FT and PMF are enabled. iOS seems to be rejecting EAPOL-Key msg

The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.
After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).
On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().
So this patch makes the default to 1000(msec) and makes it configurable.
This issue does not occur on infrastructure SAE because the
dot11RSNASAERetransPeriod is not used on it.

Currently, if multiple bss share are bridge and tagged vlan interface,
only the first instance of struct hostapd_vlan for this vlanid will have
the DVLAN_CLEAN_VLAN flag added. Thus, when this instance is removed,
the tagged vlan interface will be removed from bridge, thought other bss
might still need it. Similarily, the bridge will be left over, as the
does not have zero ports when the first instance of a struct
hostapd_vlan is freed.
This patch fixes this by having a global (per process) reference counter
for dynamic tagged vlan and dynamically created bridge interfaces, so
they are only removed after all local users are freed. (struct
hapd_interfaces *)->vlan_priv is used to hold src/ap/vlan_init.c global
per-process data like drv_priv does; right now this is only used for the
interface reference counting, but could get extended when needed. Then
possibly some vlan_global_init / vlan_global_deinit should be added, but
this is not required right now.
Additionally, vlan->configured is checked to avoid reference counter
decreasing before vlan_newlink increased them.
In order to avoid race conditions, vlan_dellink is called explicitly
after hostapd_vlan_if_remove. Otherwise there would be a short timeframe
between hostapd_vlan_if_remove and vlan_dellink during which the struct
hostapd_vlan still exists, so ap_sta_bind_vlan would try to attach
stations to it.

Commit 88b32a99d3 ('FT: Add FT AP support

sharing the older implementation of copying the WMM TSPEC from RIC for

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

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.

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.
