At least in nl80211, broadcast management frames like Probe Request
frames, may be processed multiple times per BSS if multi-BSS is active
and NL80211_CMD_FRAME event is used to deliver them. In the case of
Probe Request frames, hostapd will create multiple redundant Probe
Response frames which are problematic when many BSS are on one channel.
This problem is caused by driver_nl80211 generating an event for
wpa_supplicant_event() for each BSS, and hostapd_mgmt_rx() calls
ieee802_11_mgmt() for each BSS, too.
Fix this by processing broadcast events only for the BSS the driver
intended to. The behavior is not changed for drivers not setting a BSS.

This new mechanism allows P2P Client to request an IPv4 address from the

is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.
The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:
ip_addr_go=192.168.42.1

Devices that do not use the new mechanism. The easiest way of managing

This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter

This can be used as an alternative for the bss=<ifname> separator and

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
race condition:
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
DVLAN_CLEAN_VLAN_PORT as already there
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.
4. wlan1 removes VLAN A, does not cleanup
Solution:
This requires an inter-BSS inter-interface data structure to track the
bridge / bridge port usage within hostapd. This data structure could
also be used to track any other device-has-been-created-by-hostapd
information or when regarding interface freeing.

Currently by default, all BSS share the bridge brvlan%d.
While this is sane when no tagged-interface is given, this
is insane when different tagged interfaces are given, as
it would result in bridging those tagged interfaces.
This patch therefore uses br%s%d with %s=tagged_interface
and %d=VLAN ID as bridge name when a tagged-interface is given.

Currently, when different BSS using different tagged vlan

These events are sent as a special case to both the group interface and

Since "pairwise" is defined as an integer, the current assignment leads
to it having the value 0 or 8, which is a bit strange in debug output:

For some testing it can be useful to force the Key MIC in group

My APs generate their configuration on their own using a different
number of (vlan-enabled) bss. Currently, all my vlan_file files consist
of a single line: the wildcard line. Configuration file generation would
be easier, if the hostapd configuration file would not depend on those
simple vlan_file files.
This patch removes the need for those one-line files by using the
<device>.<vlan> naming scheme if no vlan_file is given (or that file is
empty). This should not break any existing setup, as using dynamic_vlan
with no vlan configured does not make sense anyway.

When the OS is out of random bytes in SM_STATE(WPA_PTK, AUTHENTICATION2)
in ap/wpa_auth.c, hostapd sends the sm to state DISCONNECT without
clearing ReAuthenticationRequest, resulting in an infinite loop.
Clearing sm->ReAuthenticationRequest using gdb fixes the running hostapd
instance for me. Also sm->Disconnect = TRUE should be used instead of
wpa_sta_disconnect() to make sure that the incomplete ANonce does not
get used.
Fix this issue by resetting sm->ReAuthenticationRequest even if the STA
gets disconnected and use sm->Disconnect instead of
wpa_sta_disconnect().

A non-HT capable AP on any channel could have triggered us to enable
protection regardless of own operating channel if the driver delivered

of HT40).

GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking

SME/MLME. Fix this by adding a separate callback registration for the
