Normally, WNM-Sleep Mode exit with management frame protection
negotiated would result in the current GTK/IGTK getting added into the
WNM-Sleep Mode Response frame. Some station implementations may have a
vulnerability that results in GTK/IGTK reinstallation based on this
frame being replayed. Add a new hostapd configuration parameter that can
be used to disable that behavior and use EAPOL-Key frames for GTK/IGTK
update instead. This would likely be only used with
wpa_disable_eapol_key_retries=1 that enables a workaround for similar
issues with EAPOL-Key. This is related to station side vulnerabilities
CVE-2017-13087 and CVE-2017-13088. To enable this AP-side workaround,
set wnm_sleep_mode_no_keys=1.

This adds a new hostapd configuration parameter
wpa_disable_eapol_key_retries=1 that can be used to disable
retransmission of EAPOL-Key frames that are used to install
keys (EAPOL-Key message 3/4 and group message 1/2). This is
similar to setting wpa_group_update_count=1 and
wpa_pairwise_update_count=1, but with no impact to message 1/4
retries and with extended timeout for messages 4/4 and group
message 2/2 to avoid causing issues with stations that may use
aggressive power saving have very long time in replying to the
EAPOL-Key messages.
This option can be used to work around key reinstallation attacks
on the station (supplicant) side in cases those station devices
cannot be updated for some reason. By removing the
retransmissions the attacker cannot cause key reinstallation with
a delayed frame transmission. This is related to the station side
vulnerabilities CVE-2017-13077, CVE-2017-13078, CVE-2017-13079,
CVE-2017-13080, and CVE-2017-13081.
This workaround might cause interoperability issues and reduced
robustness of key negotiation especially in environments with
heavy traffic load due to the number of attempts to perform the
key exchange is reduced significantly. As such, this workaround
is disabled by default (unless overridden in build
configuration). To enable this, set the parameter to 1.
It is also possible to enable this in the build by default by
adding the following to the build configuration:

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.

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
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.
So for FT-PSK networks, no configuration of inter-AP communication is

Separate uplink configuration (IEEE 802.1q VID) and grouping of stations
into AP_VLAN interfaces.
The int vlan_id will continue to identify the AP_VLAN interface the
station should be assigned to. Each AP_VLAN interface corresponds to an
instance of struct hostapd_vlan that is uniquely identified by int
vlan_id within an BSS.
New: Each station and struct hostapd_vlan holds a struct
vlan_description vlan_desc member that describes the uplink
configuration requested. Currently this is just an int untagged IEEE
802.1q VID, but can be extended to tagged VLANs and other settings
easily.
When the station was about to be assigned its vlan_id, vlan_desc and
vlan_id will now be set simultaneously by ap_sta_set_vlan(). So
sta->vlan_id can still be tested for whether the station needs to be
moved to an AP_VLAN interface.
To ease addition of tagged VLAN support, a member notempty is added to
struct vlan_description. Is is set to 1 if an untagged or tagged VLAN
assignment is requested and needs to be validated. The inverted form
allows os_zalloc() to initialize an empty description.
Though not depended on by the code, vlan_id assignment ensures:
* vlan_id = 0 will continue to mean no AP_VLAN interface
* vlan_id < 4096 will continue to mean vlan_id = untagged vlan id
with no per_sta_vif and no extra tagged vlan.
* vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans.
This way struct wpa_group and drivers API do not need to be changed in
order to implement tagged VLANs or per_sta_vif support.
DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only,
thus grouping of the stations for per_sta_vif can be used with
DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct
hostapd_vlan is still used to manage AP_VLAN interfaces.
MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of
VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will
continue to refer to int vlan_id.
Renaming vlan_id to vlan_desc when type changed from int to struct
vlan_description was avoided when vlan_id was also used in a way that
did not depend on its type (for example, when passed to another
function).
Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN
%d" will refer to untagged IEEE 802.1q VID.

The new acs_chan_bias configuration parameter is a space-separated list
of <channel>:<bias> pairs. It can be used to increase (or decrease) the
likelihood of a specific channel to be selected by the ACS algorithm.
The total interference factor for each channel gets multiplied by the
specified bias value before finding the channel with the lowest value.
In other words, values between 0.0 and 1.0 can be used to make a channel
more likely to be picked while values larger than 1.0 make the specified
channel less likely to be picked. This can be used, e.g., to prefer the
commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

Proxy ARP allows the AP devices to keep track of the hardware address to
IP address mapping of the STA devices within the BSS. When a request for
such information is made (i.e., ARP request, Neighbor Solicitation), the
AP will respond on behalf of the STA device within the BSS. Such
requests could originate from a device within the BSS or also from the
bridge. In the process of the AP replying to the request (i.e., ARP
reply, Neighbor Advertisement), the AP will drop the original request
frame. The relevant STA will not even know that such information was
ever requested.
This feature is a requirement for Hotspot 2.0, and is defined in IEEE
Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly
resides in the kernel bridge code, in order to optimize the performance
and simplify kernel implementation, the DHCP snooping code was added to
the hostapd.
