This was included in the AP configuration parameters, but there has
been no way to set it to anything else than the default automatic
mode. Remove this parameter and just hardcode ERP determination to
follow the automatic mode.
hostapd_wpa_auth_conf() is called on uninitialized memory and the
conditional blocks in this function may leave some fields into
uninitialized state. This can result in unexpected behavior elsewhere
since some of the variables may be used without matching #ifdef
blocks. Fix this by zeroing the memory.
The Query Response Length Limit is not allowed to be zero when
this is sent by the AP. Use 0x7F to indicate that the limit is
based on maximum number of GAS fragments.
For P2P, the p2p_connect takes in device address argument to make a
connection. However the connected event AP-STA-CONNECTED comes with
interface address. The application listening on events would find it
difficult to map interface address to the p2p device address which is
provided for connection.
Append P2P Device Address to AP-STA-CONNECTED event for P2P Client
connection. This will help applications to easily map the P2P Interface
Address to P2P Device Address on CONNECTED event. For non-P2P case, it
will just print the usual STA MAC address alone.

This offloads the station polling to driver wrappers, which may offload
it again to the driver. The hostap driver wrapper uses "real" data
frames while nl80211 uses null data frames.
Also add a specific event to indicate that a poll was successful for
future use with the nl80211 driver.
Remove the separate driver_ops functions set_cts_protect(),
set_preamble(), set_short_slot_time(), and set_ht_params(). These
belong into same set of operations as set_ap(), so there is no need
to maintain separate functions that just make the driver wrapper
more complex.
Since these have only been used with driver_nl80211.c, the driver_ops
can be removed immediately instead of maintaining backwards
compatibility period with the old functions.
The AP client isolation parameter is now available through set_ap().
driver_nl80211.c was the only driver wrapper using the set_intra_bss()
call in hostap.git, but some external trees may have used this. Once
those are cleared, the set_infra_bss() driver_ops can be removed
completely. The only remaining use case for it currently is in P2P
GO mode with wpa_supplicant.
AP mode operations were used for P2P device discovery Listen state
only during early experiments. This has now been cleaned up and
ieee802_11_set_beacon() is not called for P2P device discovery.
As such, this hack to skip Beacon configuration can be removed.
This is the first step in allowing SA Query mechanism in hostapd to be
used with drivers that implement authentication and association MLME/SME
(i.e., do not use ieee802_11.c).
Commit 17f6b90056 moved the concatenation
of WPS IEs, but did not include the validation that the IE buffer is not
NULL. In addition, the concatenation needs to be done based on the full
IE buffer instead of the parsed pointer that includes only a single
WPS IE.
Data path for stations that get successfully associated to the
hostapd but fail to get added in the driver/firmware, will not
work. In such cases, hostapd should deauth and disconnect such
stations. In such scenario, hostapd should disconnect the STAs.

The password_hash parameter was not copied in case of the integrated
authentication server (but was for RADIUS server). This broke EAP
authentication when the user entry used NT-hash.
The EAPOL authenticator was previously forcing disconnection in the WPS
use case. However, this can be benefitial operation with any IEEE 802.1X
authentication mechanism and need not be limited to WPS. This helps some
use cases like EAP-FAST where provisioning may require two
authentication runs if the authentication server does not allow the PAC
provisioning step to be used for normal data connection. While the
station would be free to decide to re-associate in such a case, not all
stations do and as such, it helps if the AP does that instead of leaving
the association up with EAPOL state machine in HELD state for 60
seconds.
When polling a station that has been inactive for a while, hostapd currently
always uses a null data frame. This is a bit strange with uAPSD clients
(though it seems to mostly work) since the EOSP bit can never be set in a
non-QoS frame. Make hostapd use QoS null data frames for probing when the
station is a QoS STA.

Wrap self-generated WPS credential for new AP settings and send that to
control interface to provide the needed information in
WPS-NEW-AP-SETTINGS for external processing.
Make the WPS processing of (Re)Association Request frame IEs conditional
on WPS support. This fixes a build issue with wps_is_20() not being
defined and makes the non-WPS build a bit smaller.
The Deauth/Disassoc TX status callbacks were ending up kicking the
station entry from kernel driver when test functionality was used to
inject Deauth/Disassoc frames from the AP with the purpose of leaving
the local association in place. Fix this by using STA flags to figure
out whether there was a pending callback for the frame that we need
to act on.
In addition, add forgotten functionality for the Disassoc TX status
callback to match the behavior with Deauth.
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.
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.
If an ER tries to send a message to a STA that is not in the middle
of WPS protocol, do not try to deliver that. This can help with issues
where an ER takes long time to reply to M1 and another Registrar has
already completed negotiation.
This change is a first step in better supporting different driver
architectures for AP mode operations with nl80211. This commit in
itself does not add new functionality, but it makes it easier to add
new AP mode parameters to address needs of drivers that have more of
the MLME/SME in firmware or kernel.
Split WPA initialization into two parts so that the Beacon frames can be
configured fully before the initial keys (GTK/IGTK) are configured. This
makes it easier for drivers that depend on the AP security mode being
fully set before the keys are configured.
