f0c7a986bb AP: Fix erroneous "station tried TKIP" error
The commit b5fd8b1833
"VHT: Do not allow use of TKIP with VHT" introduced
an off-by-one regression: a WPA/RSN 11n AP would no
longer accept stations to connect, instead it would
produce a bogus error message:
... Station tried to use TKIP with HT association.

If WNM is enabled for the build (CONFIG_WNM=y), add BSS max idle period
information to the (Re)Association Response frame from the AP and parse
this information on the station. For SME-in-wpa_supplicant case, add a
timer to handle periodic transmission of the keep-alive frame. The
actual request for the driver to transmit a frame is not yet

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.

0c01d65d6d Ignore TX status for Data frames from not associated STA
Commit d9a38716cc did this for
hostapd_eapol_tx_status() but missed the older hostapd_tx_status()
path. Address that case, too.

The TX status event may be received after a station has been
disassociated in cases where the disassociation is following a
transmission of a Data frame. Ignore such events if the STA is not
associated at the moment the event is being processed. This avoids
confusing debug entries and rescheduling of the EAPOL TX timeouts for
STAs that are still in the STA table, but are not really in active EAPOL
session.

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).

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.

17f6b90056 WPS: Wait for EAPOL-Start unless WPS 2.0 station as workaround
Extend the code that waits for the station to send EAPOL-Start before
initiating EAPOL authenticator operations to cover the case where the
station includes WPS IE in (Re)Association Request frame if that IE
does not include support for WPS 2.0. While this should not really
be needed, this may help with some deployed WPS 1.0 stations that do
not support EAPOL operations correctly and may get confused of the
EAP-Request/Identity packets that would show up twice if EAPOL-Start
is transmitted.

b8281964af Add workaround for race condition with AssocResp TX status
It may take some time for the TX status to be delivered for a
(Re)Association Response frame and if any Data frames are received
during that time, they may end up getting dropped as Class 3 frames in
not-associated state. This results in a Disassociation frame being sent
to the station and it assuming that the association has been lost.

Work around the issue by remembering that the (Re)Association Request
has already been accepted and skip the Deauth/Disassoc sending because
of the possible Class 3 frames before the TX status callback is
received.

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.

Commit bf65bc638f started the path to

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).

hostapd_eid_wpa() adds multiple IEs and the end result may not always be
correct. If WPA is enabled, WPA IE (vendor-specific) gets added in the
middle of the frame and not in the end. This would require a larger
change to spliut the IEs from WPA module into separate locations when
constructing Beacon and Probe Response frames. This is not yet addressed.
