d0cdccd307 Fix generating offloaded ACS channel list when hw_mode is set to any
When ACS is offloaded to device driver and the hw_mode parameter is set
to any, the current_mode structure is NULL which fails the ACS command.
Fix this by populating the ACS channel list with channels from all bands
when current_mode is NULL.

3188aabaf1 Add shared periodic cleanup function for AP mode
This new mechanism can be used to combine multiple periodic AP

of wakeups for the process. hostapd gets its own periodic caller and
wpa_supplicant uses the previously added timer to trigger these calls.

132dfbe8c2 Fix removal of tagged interface and bridge when multiple BSS share them
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.

e19c1d2cc7 Fix pairwise cipher suite bitfields to the driver in mixed mode
Commit 95b6bca66d ('Add rsn_pairwise bits
to set_ieee8021x() driver_ops') modified cipher configuration to use
unconditionally wpa_pairwise | rsn_pairwise. While that works for many
cases, it does not handle the case of dynamic configuration changes over
the control interface where wpa_pairwise or rsn_pairwise values may not
get cleared when the wpa parameter is modified. Fix this inconsistency
by configuring the driver with only the bits that are valid for the
currently enabled WPA/WPA2 version(s).

ef566a4d4f AP WMM: Fix integer underflow in WMM Action frame parser
The length of the WMM Action frame was not properly validated and the
length of the information elements (int left) could end up being
negative. This would result in reading significantly past the stack
buffer while parsing the IEs in ieee802_11_parse_elems() and while doing
so, resulting in segmentation fault.

This can result in an invalid frame being used for a denial of service
attack (hostapd process killed) against an AP with a driver that uses
hostapd for management frame processing (e.g., all mac80211-based
drivers).

Thanks to Kostya Kortchinsky of Google security team for discovering and
reporting this issue.

fd66aa63f4 Check Public Action length explicitly before reading Action Code
In theory, the previous version could have resulted in reading one byte
beyond the end of the management frame RX buffer if the local driver
were to deliver a truncated Public Action frame for processing. In
practice, this did not seem to happen with mac80211-based drivers and
even if it were, the extra octet would be an uninitialized value in a
buffer rather than read beyond the end of the buffer.

a0ad9e8c9e Remove WPA per-VLAN groups when no more stations remain

the group and the struct wpa_group was not freed when all station left

FATAL_FAILURE when a wpa_group is running while the AP_VLAN interface
has already been removed.
