dbfb8e82ff Remove unnecessary EVENT_RX_ACTION
This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

912b34f000 Do not process Action frames twice in hostapd SME/MLME
Commit 88b32a99d3 added support for using
some Action frame processing in hostapd for drivers that handle most of
SME/MLME internally (it added FT, this has since be extended for SA
Query and WNM). However, this was added in a way that ended up getting
both the hostapd_rx_action() and hostapd_action_rx() called for Action
frames. This could result in an attempt to process FT, SA Query, and WNM
Action frames twice.

There is need for more significant cleanup in Action frame processing in
hostapd depending on the driver type, but as a simple step to avoid
issues, skip the hostapd_action_rx() call if hostapd_rx_action()
processed the frame.

0e22b8dd4c WPS: Make sure reconfiguration timeout is not left behind on deinit
Even though this is a short timeout, it is at least theoretically
possible for the interface to be removed while waiting for
reconfiguration to start. Avoid issues with this by cancelling the
timeout on any WPS interface deinit. In theory, this should be postponed
until interface removal, but that does not fit very nicely to the
current wps_hostapd.c style.

2d2ecf51aa nl80211: Fix protected Action frame reporting for AP mode
Action frame RX report through EVENT_RX_ACTION did not indicate whether
the frame was protected or not even though that information is available
in mlme_event_mgmt(). hostapd_rx_action() has a workaround for setting
the protected flag for SA Query frames, but that did not apply for other
frames, like FT Action. This broke FT-over-DS when PMF is enabled with
newer kernel versions (i.e., the ones that do not use monitor interface
for receiving management frames).

that single BSS to be stopped and restarted. However, due to nl80211

other BSSes remained operating on the old channel.

The downside is that hostapd_disable_iface() causes deauth frames to be
sent. This is undesired but on the other hand it doesn't make sense to
create workarounds that imitate CSA's 'block tx'. For proper Tx
quiescing CSA should be properly implemented.

5afaa067d9 hostapd: Allow per-BSS (vif) configuration files
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.

"wpa_cli p2p_set per_sta_psk <0/1>" can now be used to disable/enable

When enabled, a default passphrase is still generated by the GO for

a unique PSK.

This gives more protection for the P2P group by preventing clients from
being able to derive the unicast keys used by other clients. This is

hostapd as EAP server can be configured to return cached OCSP response

for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

4345fe963e bridge: Track inter-BSS usage
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.

3aea5fbe3b hostapd: Do not change HT40 capability due to OBSS scan
The capability itself isn't really affected by an OBSS
scan, only the HT operation must then be restricted to
20 MHz. Change this, and therefore use the secondary
channel configuration to determine the setting of the
OP_MODE_20MHZ_HT_STA_ASSOCED flag.

This shouldn't really change anything functionally,
it just makes the code a little less confusing and
is also needed to implement more dynamic bandwidth

2d9ffe1e85 P2P: Fix Action frame processing if Interworking is enabled
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
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.

f826635c2d Fix EAPOL processing when STA switches between multi-BSSes
There was an issue with EAPOL frame exchanges in a multi-BSS
configuration when a station switches between the BSSes controlled by
the same hostapd process. When processing the EAPOL packet, the array of
virtual APs (iface->bss) is searched looking for the station that sent
the packet in order to identify which signal context should be used
during processing. The first match of the station in its list gets used
in the ieee802_1x_receive() function. However, even after a station has
disassociated, it remains in the list of stations pending an inactivity
timeout. This leads to the wrong hapd context (one where the station had
already disassociated) being used in some cases (if the current/active
bss entry appears in the list after one where the station has just
disassociated from) for EAPOL processing.

Fix this by checking the WLAN_STA_ASSOC flag before assuming the right
hapd context was found for the given station.

f0898e9519 Make copies basic_rates list more useful
Commit e5693c4775 added a copy of the
determined basic rate set into struct hostapd_iface, but did not
actually copy the terminating -1 value. This could be problematic if
something were to actually try to use this list since would be no way to
know what is the last entry in the list. Fix this by copying the
terminating value.

eb7719ff22 Add support for using GCMP cipher from IEEE 802.11ad
This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.

This commit does not included changes to WPS or P2P to allow GCMP to be
used.

c2d76aa624 P2P: Add p2p_client_list support for FullMAC Persistent GO
Currently, FullMAC Persistent GO can't use p2p_client_list because its
own hapd->p2p_group is NULL at ap_sta_set_authorized(). This patch
changes the processing to use sta->p2p_ie instead of
p2p_group_get_dev_addr() on FullMAC GO.

8bd0fc0e0c Force driver to disassociate STA if no room for the STA entry
When hostapd (or wpa_supplicant AP mode) limits the maximum number
of STA entries with a driver that implements SME, the driver needs
to be notified of the failed STA addition. Disassociate the STA if
the driver notifies of an association that would go beyond the
maximum number of STAs.

to request dynamic authorization requests (Disconnect-Request and
CoA-Request). This commit does not add actual processing of the
requests, i.e., this will only receive and authenticate the requests

c72bd6d49b AP: Reset STA timeout_next on driver-based-SME association
The next ap_handle_timer action was already cleared when association
is handled with user space -based SME. However, this step was missing
from the driver callback for indicating new association. This could
result in the first ap_handle_timer timeout on the new association
removing the station unexpectedly. Fix this by resetting the timeout_next
in hostapd_notif_assoc().

31b4961f02 Fix EAP/WPS to PSK transition on reassociation in authenticator
A station may move from EAP/WPS key_mgmt to PSK using re-association. In
practice, this can happen most likely with WPS when the station runs
through the provisioning step (EAP/WPS) followed by PSK authentication.
If a deauthentication event is missed from the station for whatever
reason, the EAPOL authenticator state machine could have been left
running.

This can result in various issues, including unexpected disconnection of
the station while both the 4-way handshake and EAPOL authenticator state
machines (EAP) are running at the same time when the supplicant is
trying to use PSK. Fix this by explicitly clearing EAPOL authenticator
state machine on (re)association if the new association does not use it.

Use reason code 3 (Deauthenticated because sending STA is leaving)
instead of reason code 2 (Previous authentication ot valid) in the
Deauthentication frame sent at the time a BSS is terminated. This is
more accurate reason for the message and allows the stations to get
better understand on why they were disconnected. This can be useful
especially for P2P clients that can use this as a signal that the
P2P group session was ended per P2P specification section 3.2.9.

baf513d695 Pass signal strength through, fix units
The signal strength is currently never used as the only driver reporting
it is nl80211 which uses IEEE80211_RADIOTAP_DB_ANTSIGNAL which is never
populated by the kernel. The kernel will (soon) populate
IEEE80211_RADIOTAP_DBM_ANTSIGNAL instead though, so use that.

Also, since it was never really populated, we can redefine the signal
field to be in dBm units only.

My next patch will also require knowing the signal strength of probe
requests throughout the code (where available), so add it to the
necessary APIs.

370b076197 hostapd: Only update already-set beacons when processing OLBC
When hostapd is about to start an AP using HT40, it starts a scan to
check whether it is allowed or not. If OLBC is detected before the
scan has completed, it sets the beacons prematurely.

To fix this, instead of setting all beacons when OLBC is detected,
only update the ones that have already been started.
