623ecdd5a2 Remove default ACM=1 from AC_VO and AC_VI
There is no need to mandate admission control (ACM=1) by default, so
clear that flag in the case the configuration file does not specify
wmm_ac_{vo,vi}_acm value. This gets closer to the values mentioned

The commit b5fd8b1833

473b6f22e9 Fix WPA GTK rekeying with multiple VLANs
When using multiple VLANs, GKeyDoneStations counter is not updated
properly since wpa_auth_for_each_sta() call in wpa_group_setkeys() ends
up iterating through all STAs and not just the STAs of a specific
wpa_group (VLAN). Consequently, GTK rekeying gets initialized multiple
times if more than a single group state machine exists. Fix this by
iterating only through the STAs in the specific wpa_group.

IEEE 802.11 frames regardless of their destination IP address and by

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.

less stress on the network as the idle stations won't all be trying to

52b2004285 Change reason code for AP mode BSS termination to 3
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.

c7bce24dc9 Clear EAPOL authenticator authFail for PMKSA caching/FT
This fixes a corner case where a STA that has PMKSA cache entry (or
valid FT keys) could try to use full EAPOL/EAP authentication and fail.
If the STA will then try to use the still valid PMKSA cache entry (or
FT) before the STA entry has been cleared, authFail could have been left
to TRUE. That will make EAPOL authenticator PAE state machine enter HELD
state even though authSuccess was already forced to TRUE. This results
in the STA getting disconnected even though it should be allowed to
continue with 4-way handshake. While this is unlikely to happen in
practice, it is better to get this fixed by clearing authFail when
setting authSuccess.

40d00d2bfe wpa_auth: Fix race in rejecting 4-way handshake for entropy
When there is not enough entropy and there are two station associating
at the same time, one of the stations will be rejected, but during
that rejection, the "reject_4way_hs_for_entropy" flag gets cleared. This
may allow the second station to avoid rejection and complete a 4-Way
Handshake with a GTK that will be cleared as soon as more entropy is
available and another station connects.

This reworks the logic to ban all 4-way handshakes until enough entropy
is available.

ceb997f394 Fix ap_sta_disconnect() to clear EAPOL/WPA authenticator state
Number of places in hostapd use ap_sta_disconnect() instead of
ap_sta_disassociate() or ap_sta_deauthenticate(). There are some
differences between these functions, e.g., in the area how quickly
the EAPOL state machines get deinitialized. This can result in
somewhat unexpected events since the EAPOL/WPA authenticator
state machines could remain running after deauthentication.

Address this by forcing EAPOL/WPA authenticator state machines
to disabled state whenever ap_sta_disconnect() is called instead
of waiting for the deauthentication callback or other timeout
to clear the STA.

71093e5ea9 WPS: Include WSC IE in (Re)Association Response for maybe-WPS case
If the station is indicating use of WPS, WSC IE should be added into the
(Re)Association Response frame. This is clear for the case when WSC IE
was included in the (Re)Association Request frame. However, even the
WLAN_STA_MAYBE_WPS case may actually indicate use of WPS. Assume that to
be the case when WPA/WPA2 is enabled (i.e., when the STA does not
include WPA/RSN/WSC IE while AP has WPA/RSN enabled).

9a898ee879 Avoid excessive probe response retries
Some client implementations only wait a few ms after sending a probe
request while scanning. Since probe responses are always sent at a low
rate this can eat quite some airtime and it might be impossible to get
the frame out before the client leaves the channel again. If the client
leaves before all probe reponses where acked this can cause the probe
reponse to be retried quite often consuming even more airtime.

Hence, add a new noack flag to the driver's send_mlme callback that
allows hostapd to request whether the driver should expect an ACK for
this frame or not.

Use the new noack-policy only for broadcast probe requests that contain
a wildcard SSID.

4dc03726de Delay STA entry removal until Deauth/Disassoc TX status in AP mode
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.

This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.

e4bf4db907 Work around SNonce updates on EAPOL-Key 1/4 retransmission
Some deployed supplicants update their SNonce for every receive
EAPOL-Key message 1/4 even when these messages happen during the
same 4-way handshake. Furthermore, some of these supplicants fail
to use the first SNonce that they sent and derive an incorrect PTK
using another SNonce that does not match with what the authenticator
is using from the first received message 2/4. This results in
failed 4-way handshake whenever the EAPOL-Key 1/4 retransmission
timeout is reached. The timeout for the first retry is fixed to
100 ms in the IEEE 802.11 standard and that seems to be short
enough to make it difficult for some stations to get the response
out before retransmission.

Work around this issue by increasing the initial EAPOL-Key 1/4
timeout by 1000 ms (i.e., total timeout of 1100 ms) if the station
acknowledges reception of the EAPOL-Key frame. If the driver does
not indicate TX status for EAPOL frames, use longer initial
timeout (1000 ms) unconditionally.

e926bcffd8 hostapd: Inherit correct MAC address for AP VLAN interfaces
When using multiple vifs and dynamic vlan tagging is enabled on any
interface, the created AP VLAN interfaces get the BSSID of the first
AP mode interface instead of the BSSID of the corresponding AP mode
interface.

Example:

wlan0 - xx:xx:xx:xx:x0
wlan1 - xx:xx:xx:xx:x1

Assume a STA connects to the AP interface wlan1 and gets a dynamic
VLAN tag 100 assigned by the RADIUS server. Hostapd will create an AP
VLAN interface wlan1.100 but doesn't set an address for this interface
which results in wlan1.100 getting the same address as wlan0:

wlan1.100 - xx:xx:xx:xx:x0

As a result the STA that was moved to wlan1.100 isn't able to finish its
4-way handshake since mac80211 won't pass its frames to wlan1.100 due to
the different address.

To fix this issue make use of the address of the AP interface when
creating an AP VLAN interface.

f39b07d7ed hostapd: Allow coexistance of HT BSSes with WEP/TKIP BSSes
In multi BSS setups it wasn't possible to set up an HT BSS in
conjunction with a WEP/TKIP BSS. HT needed to be turned off entirely
to allow WEP/TKIP BSSes to be used.

In order to allow HT BSSes to coexist with non-HT WEP/TKIP BSSes add a
new BSS conf attribute "disable_11n" which disables HT capabilities on a
single BSS by suppressing HT IEs in the beacon and probe response
frames. Furthermore, mark all STAs associated to a WEP/TKIP BSS as
non-HT STAs. The disable_11n parameter is used internally; no new entry
is parsed from hostapd.conf.

This allows a non-HT WEP/TKIP BSS to coexist with a HT BSS without
having to disable HT mode entirely. Nevertheless, all STAs associated to
the WEP/TKIP BSS will only be served as if they were non-HT STAs.

0d7e5a3a29 Allow AP mode to disconnect STAs based on low ACK condition
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.

cee7d66b1d hostapd: Start removing struct hostapd_driver_ops abstraction
Commit bf65bc638f started the path to
add this new abstraction for driver operations in AP mode to allow
wpa_supplicant to control AP mode operations. At that point, the
extra abstraction was needed, but it is not needed anymore since
hostapd and wpa_supplicant share the same struct wpa_driver_ops.

Start removing the unneeded abstraction by converting
send_mgmt_frame() to an inline function, hostapd_drv_send_mlme().
This is similar to the design that is used in wpa_supplicant and
that was used in hostapd in the past (hostapd_send_mgmt_frame()
inline function).

On Linux, verify that the kernel entropy pool is capable of providing

force first two 4-way handshakes to fail while collecting entropy

and allow the AP to function based on the combination of /dev/urandom
and whatever data has been collected into the internal entropy pool.

bbb921daaa Maintain internal entropy pool for augmenting random number generation
By default, make hostapd and wpa_supplicant maintain an internal
entropy pool that is fed with following information:

hostapd:
- Probe Request frames (timing, RSSI)
- Association events (timing)
- SNonce from Supplicants

wpa_supplicant:
- Scan results (timing, signal/noise)
- Association events (timing)

The internal pool is used to augment the random numbers generated
with the OS mechanism (os_get_random()). While the internal
implementation is not expected to be very strong due to limited
amount of generic (non-platform specific) information to feed the
pool, this may strengthen key derivation on some devices that are
not configured to provide strong random numbers through
os_get_random() (e.g., /dev/urandom on Linux/BSD).

This new mechanism is not supposed to replace proper OS provided
random number generation mechanism. The OS mechanism needs to be
initialized properly (e.g., hw random number generator,
maintaining entropy pool over reboots, etc.) for any of the
security assumptions to hold.

If the os_get_random() is known to provide strong ramdom data (e.g., on
Linux/BSD, the board in question is known to have reliable source of
random data from /dev/urandom), the internal hostapd random pool can be
disabled. This will save some in binary size and CPU use. However, this
should only be considered for builds that are known to be used on
devices that meet the requirements described above. The internal pool
is disabled by adding CONFIG_NO_RANDOM_POOL=y to the .config file.

3642c4313a Annotate places depending on strong random numbers
This commit adds a new wrapper, random_get_bytes(), that is currently
defined to use os_get_random() as is. The places using
random_get_bytes() depend on the returned value being strong random
number, i.e., something that is infeasible for external device to
figure out. These values are used either directly as a key or as
nonces/challenges that are used as input for key derivation or
authentication.

The remaining direct uses of os_get_random() do not need as strong
random numbers to function correctly.

1bdb7ab3af Re-initialize GMK and Key Counter on first station connection
This adds more time for the system entropy pool to be filled before
requesting random data for generating the WPA/WPA2 encryption keys.
This can be helpful especially on embedded devices that do not have
hardware random number generator and may lack good sources of
randomness especially early in the bootup sequence when hostapd is
likely to be started.

GMK and Key Counter are still initialized once in the beginning to
match the RSN Authenticator state machine behavior and to make sure
that the driver does not transmit broadcast frames unencrypted.
However, both GMK (and GTK derived from it) and Key Counter will be
re-initialized when the first station connects and is about to
enter 4-way handshake.

all interfaces.

This is relatively minimal change to address the sharing of the
state among multiple struct hostapd_data instances. More cleanup
can be done separately to remove unnecessary copies of information.

944814106e WPS: Do not disable AP PIN permanently, only slow down attacks
As a compromise between usability and security, do not disable
AP PIN permanently based on failed PIN validations. Instead, go to
AP Setup Locked state for increasing amount of time between each
failure to slow down brute force attacks against the AP PIN.

This avoids problems with some external Registrars that may try
to use the same PIN multiple times without user input. Now, the
user will still be able to fix the PIN and try again later while
a real attack is delayed enough to make it impractical.

6195adda9b WPS: Allow AP to start in Enrollee mode without AP PIN for probing
In theory, this should not really be needed, but Windows 7 uses
Registrar mode to probe AP's WPS capabilities before trying to use
Enrollee and fails if the AP does not allow that probing to happen.
This allows the AP to start as an Enrollee and send M1, but refuse
to continue beyond that (M3 will not be sent if AP PIN is not known).

67ccef7e6c FT: Send RRB data directly when managed by same hostapd process
This makes it easier (and a bit faster) to handle multiple local
radios with FT. There is no need to depend on l2_packet in that
case since the frame can be delivered as a direct function call.
