Previously only couple of AKM suite selectors were converted into
NL80211_ATTR_AKM_SUITES. Add rest of the AKM suites here. However, since
the current kernel interface has a very small limit
(NL80211_MAX_NR_AKM_SUITES = 2), add the attribute only when no more
than that limit entries are included. cfg80211 would reject the command
with any more entries listed.
This needs to be extended in cfg80211/nl80211 in a backwards compatible
manner, so this seems to be the best that can be done for now in user
space. Many drivers do not use this attribute, so must not reject the

SM Power Save was described in somewhat unclear manner in IEEE Std

was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.

A driver supports FT if it either supports SME or the

when an AP supports both WPA-EAP and FT-EAP but the driver doesn't

Add the new set_key() parameter "key_flag" to provide more specific
description of what type of a key is being configured. This is needed to
be able to add support for "Extended Key ID for Individually Addressed
Frames" from IEEE Std 802.11-2016. In addition, this may be used to
replace the set_tx boolean eventually once all the driver wrappers have
moved to using the new key_flag.
The following flag are defined:
KEY_FLAG_MODIFY
Set when an already installed key must be updated.
So far the only use-case is changing RX/TX status of installed
keys. Must not be set when deleting a key.
KEY_FLAG_DEFAULT
Set when the key is also a default key. Must not be set when
deleting a key. (This is the replacement for set_tx.)
KEY_FLAG_RX
The key is valid for RX. Must not be set when deleting a key.
KEY_FLAG_TX
The key is valid for TX. Must not be set when deleting a key.
KEY_FLAG_GROUP
The key is a broadcast or group key.
KEY_FLAG_PAIRWISE
The key is a pairwise key.
KEY_FLAG_PMK
The key is a Pairwise Master Key (PMK).
Predefined and needed flag combinations so far are:
KEY_FLAG_GROUP_RX_TX
WEP key not used as default key (yet).
KEY_FLAG_GROUP_RX_TX_DEFAULT
Default WEP or WPA-NONE key.
KEY_FLAG_GROUP_RX
GTK key valid for RX only.
KEY_FLAG_GROUP_TX_DEFAULT
GTK key valid for TX only, immediately taking over TX.
KEY_FLAG_PAIRWISE_RX_TX
Pairwise key immediately becoming the active pairwise key.
KEY_FLAG_PAIRWISE_RX
Pairwise key not yet valid for TX. (Only usable with Extended Key ID
support.)
KEY_FLAG_PAIRWISE_RX_TX_MODIFY
Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX.
KEY_FLAG_RX_TX
Not a valid standalone key type and can only used in combination
with other flags to mark a key for RX/TX.

Linux kernel v4.17 added the ability to request sending controlled port
frames (e.g., IEEE 802.1X controlled port EAPOL frames) via nl80211
instead of a normal network socket. Doing this provides the device
driver with ordering information between the control port frames and the
installation of keys. This empowers it to avoid race conditions between,
for example, PTK replacement and the sending of frame 4 of the 4-way
rekeying handshake in an RSNA. The key difference between the specific
control port and normal socket send is that the device driver will
certainly get any EAPOL frames comprising a 4-way handshake before it
gets the key installation call for the derived key. By flushing its TX
buffers it can then ensure that no pending EAPOL frames are
inadvertently encrypted with a key that the peer will not yet have
installed.
Add a CONTROL_PORT flag to the hostap driver API to report driver
capability for using a separate control port for EAPOL frames. This
operation is exactly like an Ethernet send except for the extra ordering
information it provides for device drivers. The nl80211 driver is
updated to support this operation when the device reports support for
NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211. Also add a driver op
tx_control_port() for request a frame to be sent over the controlled
port.

Normally nl80211 driver will attempt to strictly control what bridge
given interface is put in. It'll attempt to remove it from an existing
bridge if it doesn't match the configured one. If it's not in a bridge
it'll try to put it into one. If any of this fails then hostapd will
bail out and not set up the BSS at all.
Arguably that's reasonable since it allows to set the BSS up coherently
with regard to EAPOL handling as well as allows extra interactions with
things like FDB. However, not all hostapd drivers interact with bridge=
the same way. One example is atheros. Therefore it's not clear what the
desired behavior should be if consistency across drivers is considered.
There's a case where one might want to use a non-native Linux bridge,
e.g., openvswitch, in which case regular ioctls won't work to put an
interface into a bridge, or figure out what bridge an interface is in.
The underlying wireless driver can still be an ordinary nl80211 driver.
This change relaxes the bridge setup failure so that hostapd still
starts even if it fails to add an interface into a configured bridge
name. It still sets up all the necessary sockets (including the
configured bridge=) so EAPOL handling should work fine. This then leaves
it to the system integrator to manage wireless interface as bridge ports
and possibly fdb hints too.

IEEE P802.11ay defines Enhanced Directional Multi-Gigabit (EDMG) STA and

nl80211 provides the driver's EDMG capabilities from the kernel
using two new attributes:
NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16
GHz channel(s) that are supported by the driver.
NL80211_BAND_ATTR_EDMG_BW_CONFIG - represents the channel bandwidth
configurations supported by the driver.
The driver's EDMG capabilities are stored inside struct hostapd_hw_modes.
As part of the connect request and starting AP, EDMG parameters are
passed as part of struct hostapd_freq_params.
The EDMG parameters are sent to the kernel by using two new attributes:
NL80211_ATTR_WIPHY_EDMG_CHANNEL and NL80211_ATTR_WIPHY_EDMG_BW_CONFIG
which specify channel and bandwidth configuration for the driver to use.

HE (802.11ax) is also supported on 2.4 GHz. And the 2.4 GHz band isn't
supposed to use VHT operations. Some codepaths in wpa_supplicant will
therefore not initialize the freq->bandwidth or the freq->center_freq1/2
members. As a result, the nl80211_put_freq_params() will directly return
an error (-1) or the kernel will return an error due to the invalid
channel definition.
Instead, the channel definitions should be created based on the actual

Commit d896874f86 ("nl80211: Indicate 802.1X 4-way handshake offload

driver that it should offload the 802.1X handshake. However, this field
was existing and used for a different offload API. This causes
wpa_supplicant to send a connect request without the WANT_1X_HS flag and
the subsequent set-pmk is rejected causing the connection to fail. Fix
that by introducing a new flag req_handshake_offload so the offloads are
no longer entangled.

ETSI EN 301 893 v2.1.1 (2017-05) standard defines a new channel access
mechanism that all devices (WLAN and LAA) need to comply with.
In previous versions the device was allowed by ETSI to implement
802.11 channel access mechanism based on a set of priority classes
which are taken from 802.11. According of the new standard there
might be some exceptions which require ETSI countries to follow
more restrictive rules. In such a case the AP's wmm IE need to
comply with ETSI limitation. To be able to do so the regulatory
domain passes the new limitation values if needed.
Implement this, by storing it and use it to calculate the new

The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."
When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.
Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

For hostapd/AP, this mechanism is enabled by setting

reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report

more Collocated Interference Report Elements (each including the

Commit 3f53c006c7 ('nl80211: Ignore
disconnect event in case of locally generated request') made
wpa_supplicant ignore the next received disconnect event for cases where
wpa_supplicant itself requested a disconnection. This can result in
ignoring a disconnection notification in some cases.
Considering a P2P Client receiving disconnect event from the kernel
after a P2P group is started, drv->ignore_next_local_disconnect is
cleared to 0, then wpa_driver_nl80211_disconnect() will be called during
the removal of the group, in which drv->ignore_next_local_disconnect is
set to 1 by mistake.
Do not allow ignore_next_local_{disconnect,deauth} to be set to 1 if the
driver is not in associated state (drv->associated is 0) to avoid this
type of cases.

When we start hostapd having Hotspot 2.0 configuration with interface
already added to bridge interface, addition and deletion of new neighbor
to bridge ip neighbor table fails.
This is since 'bss->added_if_into_bridge' is not set which only allows
'drv->rtnl_sk' (nl_sock for NETLINK_ROUTE) allocation needed for bridge
ip neighbor table.
Add a new bit 'already_in_bridge' and set it when interface is already
added to bridge by some external component. Check this bit in addition
to 'bss->added_if_into_bridge' for 'drv->rtnl_sk' allocation done in
i802_init().
Now 'drv->rtnl_sk' is closed in wpa_driver_nl80211_deinit() regardless of
'bss->added_if_into_bridge' since when we have 'bss->already_in_bridge'
case too, this need to be removed.

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

The current cfg80211 limit for the maximum NL80211_ATTR_PMK length is
48, so anything larger than that will result in the operation completely
failing. Since the PMKSA entries can be used without the PMK for most
purposes (the main use case for PMK currently is offloaded FILS
authentication), try to go ahead by configuring only the PMKID for the
case where 64-octet PMK is needed (which is currently limited to only
DPP with NIST P-521 and brainpoolP512r1 curves). This can fix DPP
connections with drivers that expect to get the PMKID through this

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.

wpa_supplicant tries to reinitialize an interface when a previously
removed netdev is restored (e.g., re-insert a USB dongle). If that

If the interface state is changed quickly enough, wpa_supplicant may
receive the netlink message for the !IFF_UP event when the interface
has already been brought up and would ignore the next netlink IFF_UP
message, missing the MAC change.
Fix this by also reloading the MAC address when a !IFF_UP event is
received with the interface up, because this implies that the
interface went down and up again, possibly changing the address.

Following commit a70cd0db87 ('Don't
register for Beacon frames for IEEE 802.11ad AP'),
nl80211_get_wiphy_data_ap() is unconditionally called when starting AP.
This function tries to register for Beacon frames RX which fails for
some driver which don't support such registration and do not need it in
case the driver implements AP mode SME functionality.
Fix this by conditionally calling nl80211_get_wiphy_data_ap() like prior
to commit a70cd0db87.

If vendor_scan_cookie is set to 0 after the scan_abort due to the scan
timeout ends in a cookie mismatch when processing the following
QCA_NL80211_VENDOR_SUBCMD_SCAN_DONE indication. This ends up considering
the scan results as being for an external scan and thus the current
ongoing scan is not removed from the radio_work. Hence, do not reset
this vendor_scan_cookie after the scan abort so that the scan completion
event gets processed properly and vendor_scan_cookie gets cleared at
that point.

This allows kernel to force disconnection if something kills the
wpa_supplicant process in a manner that does not allow proper cleanup to
be performed. The association is not supposed to be allowed to continue
after process has ended since there are number of operations that
wpa_supplicant may need to do during the association.

Authentication and Deauthentication frames are not used in DMG/IEEE
802.11ad networks. For DMG/IEEE 802.11ad the following was implemented:
Upon receiving association request, allocate the sta object and
initialize it as if authentication took place. Upon receiving
disassociation, deallocate the sta object.
ap_sta_disassociate/ap_sta_deauthenticate/ap_sta_disconnect all use
disassociation instead of deauthentication. In driver_nl80211,
i802_sta_deauth() is routed to i802_sta_disassoc().

It was possible that nl80211_get_hw_feature_data() function would return
NULL when num_modes is not set to zero. This might result in a later crash
when accessing hw.modes. This may be reproduced with hwsim oom tests, for
example, dbus_connect_oom.
Fix that by zeroing num_modes if NULL is returned.

Add the following parameters to scan request:
1. Dwell time on each channel.
2. Whether the specified dwell time is mandatory.
In addition, add to scan results info the time that the scan actually
started, and to each scan result the time the beacon/probe was received,
both in terms of TSF of the BSS that the interface that requested the
scan is connected to (if available).
Add flags to indicate whether the driver supports dwell time
configuration and scan information reporting.
This scan configuration and information is required to support beacon

On a connect nl80211 event, wpa_supplicant uses
wpa_driver_nl80211_get_ssid() to fetch the current associated SSID to
compare to existing configurations. However,
wpa_driver_nl80211_get_ssid() uses drv->ssid, which is a cached value.
It is set when we explicitly initial a connect request using
wpa_supplicant. If the association was initiated outside of
wpa_supplicant, we need another way to populate drv->ssid. This commit
sets drv->ssid based on cfg80211 BSS information on connect/associate
nl80211 events.

Commit adcd7c4b0b ('nl80211: Support
vendor scan together with normal scan') made the drv->scan_state updates
for NL80211_CMD_NEW_SCAN_RESULTS and NL80211_CMD_SCAN_ABORTED
conditional on drv->last_scan_cmd being NL80211_CMD_TRIGGER_SCAN. This
missed the part about the possibility of last_scan_cmd == 0 and an
externally started cfg80211 scan is ending. This could leave
drv->scan_state into SCAN_STARTED state even after the scan was
completed. Consequently, hwsim test cases could get stuck in reset()
handler waiting for scan to terminate.
Fix this by updating drv->scan_state also in drv->last_scan_cmd == 0
case.

This adds support for nl80211 NL80211_CMD_SET_MULTICAST_TO_UNICAST
command.
By setting the new hostapd configuration option multicast_to_unicast=1,
hostapd configures this AP to perform multicast to unicast conversion.
When enabled, all multicast packets with ethertype ARP, IPv4, or IPv6
(possibly within an 802.1Q header) will be sent out to each station once
with the destination (multicast) MAC address replaced by the station's
MAC address. Note that this may break certain expectations of the
receiver, e.g., the ability to drop unicast IP packets encapsulated in
multicast L2 frames, or the ability to not send destination unreachable
messages in such cases.
This also does not implement Directed Multicast Service (DMS).

Do not use the generic bss_info_handler() design to fetch all scan
results into temporary memory buffer. Instead, use a separate BSS info
handler that fetches the requested information without fully parsing the
BSS entries and without allocating any memory for collecting all the
results.
This is also simplifying bss_info_handler() and nl80211_parse_bss_info()
design by getting rid of the special case that was used only for
nl80211_get_assoc_freq() and not normal scan result fetching.

The way the removal of duplicated (one per frequency) BSS entries in the
cfg80211 scan results were removed in driver_nl80211_scan.c
bss_info_handler() depended on having the full scan results available to
allow iteration through the other entries. This is problematic for the
goal of being able to optimize memory allocations for scan result
fetching in a manner that would not build the full result buffer in
memory.
Move this duplicate removal into bss.c since it has sufficient
information available for doing the same determination of which one of
two BSS entries is more current.

This untangles the NL80211_CMD_GET_SURVEY handler loop from
NL80211_CMD_GET_SCAN processing so that the per-channel noise
information can be fetched with a common function to a local data
structure that can then be easily used to update individual scan results
(a single BSS) instead of having to go through a full set of scan
results. This is a step towards optimizing scan result fetching without
having to allocate memory for all entries at the same time.
