When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.
Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

Rework the Acct-Session-Id and Acct-Multi-Session-Id implementation to
give better global and temporal uniqueness. Previously, only 32-bits of
the Acct-Session-Id would contain random data, the other 32-bits would
be incremented. Previously, the Acct-Multi-Session-Id would not use
random data. Switch from two u32 variables to a single u64 for the
Acct-Session-Id and Acct-Multi-Session-Id. Do not increment, this serves
no legitimate purpose. Exclusively use os_get_random() to get quality
random numbers, do not use or mix in the time. Inherently take a

When multiple interfaces across mutiple radios are started using a
single instance of hostapd, they all come up at different times
depending upon how long the ACS and HT scan take on each radio. This
will result in stations (that already have the AP profile) associating
with the first interfaces that comes up. For example in a dual band
radio case (2G and 5G) with ACS enabled, 2G always comes up first
because the ACS scan takes less time on 2G and this results in all
stations associating with the 2G interface first.
This feature brings up all the interfaces at the same time. The list of
interfaces specified via hostapd.conf files on the command line are all
marked as sync interfaces. All the interfaces are synchronized in
hostapd_setup_interface_complete().
This feature is turned on with '-S' commmand line option.

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.

Proxy ARP allows the AP devices to keep track of the hardware address to
IP address mapping of the STA devices within the BSS. When a request for
such information is made (i.e., ARP request, Neighbor Solicitation), the
AP will respond on behalf of the STA device within the BSS. Such
requests could originate from a device within the BSS or also from the
bridge. In the process of the AP replying to the request (i.e., ARP
reply, Neighbor Advertisement), the AP will drop the original request
frame. The relevant STA will not even know that such information was
ever requested.
This feature is a requirement for Hotspot 2.0, and is defined in IEEE
Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly
resides in the kernel bridge code, in order to optimize the performance

Currently, struct hostapd_vlan is a per-BSS data structure which
also contains informations about whether to remove the bridge
or clear wlan / tagged-vlan interface from the bridge.
In a multi-interface multi-BSS setup, this can lead to the following

1. wlan0 creates VLAN A, sets DVLAN_CLEAN_BR and DVLAN_CLEAN_VLAN_PORT
2. wlan1 creates VLAN A, does not set DVLAN_CLEAN_BR and

3. wlan0 removes VLAN A, removes tagged-interface from the bridge
but not the bridge.
Now wlan1 VLAN A is unusable due to the missing uplink.

done using Association Request/Response or with Reassociation
Request/Response frames.
This is needed to allows WPS PBC session overlap detection to work
with drivers that process Probe Request frames internally. This
code is is run in hostapd, but the wpa_supplicant AP mode did not
have call to the hostapd_probe_req_rx() function even though it
registered handlers for hostapd Probe Request RX callbacks.
Add a callback for station's authorized transitions
to allow wpa_supplicant to emit events in DBus.

The nl80211 driver can report low ACK condition (in fact it reports
complete loss right now only). Use that, along with a config option, to
disconnect stations when the data connection is not working properly,
e.g., due to the STA having went outside the range of the AP. This is
disabled by default and can be enabled with disassoc_low_ack=1 in
hostapd or wpa_supplicant configuration file.

This is not needed anymore and just makes things more difficult
to understand, so move the remaining function pointers to direct
function calls and get rid of the struct hostapd_driver_ops.
send_eapol, set_key, read_sta_data, sta_clear_stats,
set_radius_acl_auth, set_radius_acl_expire, and set_beacon
to use inline functions instead of extra abstraction.
