This can be used to test replay protection. The "RESET_PN" command in
wpa_supplicant and "RESET_PN <addr>" command in hostapd resets the local
counters to zero for the last configured key. For hostapd, the address
parameter specifies which STA this operation is for or selects GTK
("ff:ff:ff:ff:ff:ff") or IGTK ("ff:ff:ff:ff:ff:ff IGTK").
This functionality is for testing purposes and included only in builds

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

hostapd allows arbitrary AP PIN to be used in WPS. This means that
setting ap_pin to a zero length string ends up enabling AP PIN so that
external registrars can use this specific zero lenth ap_pin value. There
are apparently some APs that have used this invalid configuration with
unintended results. While the proper fix for that is to fix the
component that generates the invalid configuration, hostapd can also
reject such values since the likelihood of a real world use case for
zero length AP PIN (Device Password) is minimal.
Start interpreting zero length ap_pin parameter value as a request to
"unset" the previously set value in hostapd.conf (or if not previously
set, leave it unset). With this, a hostapd.conf file including the
"ap_pin=" line will end up getting interpretted just like that same file
with the ap_pin parameter completely removed, i.e., with AP PIN being
disabled.

Enable use of FT RRB without configuring each other AP locally. Instead,
broadcast messages are exchanged to discover APs within the local
network.
When an R0KH or R1KH is discovered, it is cached for one day.
When a station uses an invalid or offline r0kh_id, requests are always
broadcast. In order to avoid this, if r0kh does not reply, a temporary
blacklist entry is added to r0kh_list.
To avoid blocking a valid r0kh when a non-existing pmk_r0_name is
requested, r0kh is required to always reply using a NAK. Resend requests
a few times to ensure blacklisting does not happen due to small packet
loss.
To free newly created stations later, the r*kh_list start pointer in
conf needs to be updateable from wpa_auth_ft.c, where only wconf is

Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.
This patch introduces the generation of the required PMKs locally for

So for FT-PSK networks, no configuration of inter-AP communication is

published by Denton Gentry and Avery Pennarun.
http://research.google.com/pubs/pub45429.htmlhttps://arxiv.org/abs/1608.01725

2. If enabled, store the Probe Request and (Re)Associate Request frame in

4. Implement a "signature qq:rr:ss:tt:uu:vv" command
in hostapd_cli to retrieve the signature.
Signatures take the form of a text string. For example, a signature

Add configuration options that control publishing of fine timing
measurement (FTM) responder and initiator functionality via bits 70, 71
of Extended Capabilities element. Typically, FTM functionality is
controlled by a location framework outside hostapd. When framework is
activated, it will use hostapd to configure the AP to publish the FTM
functionality. See IEEE P802.11-REVmc/D7.0, 9.4.2.27.

Some deployed stations incorrectly consider nsts capability in
(Re)Association Response frame as required capability instead of maximum
capability and if it is greater than station's capability then beamform
will not happen in uplink traffic.
This commit adds support for an optional workaround to use station's
nsts capability in (Re)Association Response frame if the station's nsts
is less than AP by using the use_sta_nsts=1 configuration parameter.
This configuration is introduced in this commit and it is disabled by
default.

This fragment defines how the Android init system should start hostapd
as a standalone service. Previously, hostapd was fork/exec'd from
Android's netd. This left hostapd with some dangling file descriptors
and a process parent minimally interested in acting as init for child
processes.

This introduces an optinal command line parameter '-i' to override the
value of the 'interface' attribute in hostapd.conf files. This change
enables the reuse of the configuration files for the concurrent
instances of hostapd. An ability to dynamically assign the interface
names simplifies the usages of hostapd service in the automated
emulations of the wireless environments.

Add FTM range request via RRM. The AP sends Radio measurement request
with FTM range request as a request for the receiving STA to send FTM
requests to the given list of APs. The neighbor report part of the
request is taken from the neighbor database.
The control interface command is:
REQ_RANGE <dst addr> <rand_int> <min_ap> <responder> [<responder>..]
dst addr: MAC address of an associated STA
rand_int: Randomization Interval (0..65535) in TUs
min_ap: Minimum AP Count (1..15); minimum number of requested FTM ranges
between the associated STA and the listed APs
responder: List of BSSIDs for neighboring APs for which a measurement
is requested

All parameters for a neighbor must be updated at once; Neighbor Report
element and SSID are mandatory, LCI and civic are optional. The age of
LCI is set to the time of neighbor update.
The control interface API is:

To delete a neighbor use:
REMOVE_NEIGHBOR <BSSID> <SSID>

This was only used for providing an option to use linux/if_packet.h
instgead of netpacket/packet.h in src/ap/iapp.c. However,
netpacket/packet.h is nowadays commonly available and hostapd already
depends on it through src/l2_packet/l2_packet_linux.c, so there is no
need to continue to provide this option for the kernel header.
