Call nl80211_send_monitor() directly instead of going through
wpa_driver_nl80211_send_frame() for the case where monitor interface is
used for AP mode management purposes. drv->use_monitor has to be 1 in
this code path, so wpa_driver_nl80211_send_frame() was calling
nl80211_send_monitor() unconditionally for this code path and that extra

Netlink dump message may be interrupted if an internal inconsistency is
detected in the kernel code. This can happen, e.g., if a Beacon frame
from the current AP is received while NL80211_CMD_GET_SCAN is used to
fetch scan results. Previously, such cases would end up not reporting an
error and that could result in processing partial data.
Modify this by detecting this special interruption case and converting
it to an error. For the NL80211_CMD_GET_SCAN, try again up to 10 times
to get the full response. For other commands (which are not yet known to
fail in similar manner frequently), report an error to the caller.

This commit changes the failover behavior of RADIUS client. Commit
27ebadccfb ("RADIUS client: Cease endless retry for message for
multiple servers") changed the retry logic, causing RADIUS client to
wait RADIUS_CLIENT_NUM_FAILOVER + 1 timeouts before failing over the
first time. Prior to that commit, RADIUS client would wait
RADIUS_CLIENT_NUM_FAILOVER timeouts before each failover. This was
caused by moving the entry->attempts > RADIUS_CLIENT_NUM_FAILOVER
comparison to before the retry attempt, where entry->attempts is
incremented.
The commit in question set entry->attempts in radius_change_server to 1
instead of 0, so RADIUS client would still only wait
RADIUS_CLIENT_NUM_FAILOVER timeouts for subsequent failovers, the same
as the original behavior.
This commit changes the comparison so the initial failover now happens
after waiting RADIUS_CLIENT_NUM_FAILOVER timeouts, as it did originally.
It also changes the RADIUS_CLIENT_MAX_FAILOVER comparison to prevent an
additional attempt to the primary server after the final failover.

When using FT wildcard feature, the inter-AP protocol will send
broadcast messages to discover related APs.
For example,

ff:ff:ff:ff:ff:ff
12/6 16:24:43 FT: Send out sequence number request to
ff:ff:ff:ff:ff:ff
If you have multiple interfaces/BSSs in a single hostapd process,
hostapd_wpa_auth_oui_iter() returned 1 after the first interface was
processed. Iteration in for_each_interface() will be stopped since it
gets a non-zero return value from hostapd_wpa_auth_oui_iter().
Even worse, the packet will not be sent to ethernet because
for_each_interface() returns non-zero value. hostapd_wpa_auth_send_oui()
will then return data_len immediately.
To prevent this, hostapd_wpa_auth_oui_iter() should not return 1 after
any successful transmission to other interfaces, if the dst_addr of
packet is a multicast address.

We use the wired driver for wired port authentication with a slight
extension to add the port into a bridge upon successful authentication
and to remove it from the bridge when the session terminates.
Our expectation was that the Session-Timeout configuration at the RADIUS
server is respected, i.e. the session is terminated and would need
re-authentication - like it is working for WLAN sessions over the
nl80211 driver. Alas, it turned out the session is not terminated with
the wired driver.
It turned out that when ap_handle_session_timer() is executed, the
sta->flags of the wired port has only the WLAN_STA_AUTHORIZED bit set.
The WLAN_STA_AUTH bit, which is used to check whether the STA needs to
be de-authenticated, is missing.
Extend the check for any of the WLAN_STA_(AUTH | ASSOC | AUTHORIZED)
bits to solve this issue with the wired driver. That should not have any
side-effect for the WLAN cases since WLAN_STA_AUTH is expected to always
be set for those when there is an ongoing session and separate checks
for ASSOC and AUTHORIZED don't change this.

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.

In repeater configuration, both AP and STA wireless interfaces may be
included into the same bridge. In this case the following race condition
may occur: wpa_supplicant and hostapd are started, then hostapd clients
are connected before wpa_supplicant connects to remote AP. EAPOL packets
between hostapd and its clients are detected by wpa_supplicant on bridge
interface, prematurely disabling the workaround.
One possible option to fix this issue is to check EAPOL destination MAC
in wpa_supplicant and disable workaround only if EAPOL packet on bridge
interface is indeed intended for wpa_supplicant.

The case where the old RSNE included one or more PMKIDs and that RSNE
was followed by another IE was handled incorrectly since the
os_memmove() to move the end of the buffer when removing old PMKIDs was
stopping copying at the end of the RSNE, not the end of the IE buffer.
This could result in corrupting the IE that followed the RSNE. In
practice, this broke FT-SAE with H2E by corrupting the RSNXE that is in
the buffer after the RSNE.
Fix this by copying the full end of the buffer (i.e., including the
following RSNXE in the visible error case) when removing the old PMKIDs.

parsed IE was able to drop the const) and copy the const input data to a
temporary buffer for processing and modification instead of allowing the
input data to be modified.

Commit 947b5a1532 ("P2P: Stop listen state if Action frame TX is
needed on another channel") added an optimization for P2P response
transmission in certain concurrent operation cases. However, it did not
take into account possibility of the driver not being in listen
state (p2p->drv_in_listen == 0) and could end up getting stuck with the
P2P state machine in a manner that made the device not listen for
following messages. This showed up in following manner in the debug log:
P2P: Starting short listen state (state=SEARCH)
P2P: Driver ended Listen state (freq=2437)
process received frame and send a response
P2P: Stop listen on 0 MHz to allow a frame to be sent immediately on 2437 MHz
P2P: Clear timeout (state=SEARCH)
--> state machine stuck
Fix this by adding drv_in_listen > 0 condition for the optimization to
stop the listen operation in send_action() resulting in scheduled TX.

wpa_validate_wpa_ie() was already extended to cover these cases with
WPA_INVALID_PMKID return value, but hostapd_notif_assoc() did not have
code for mapping this into the appropriate status code
(STATUS_INVALID_PMKID) and ended up using the default
(WLAN_STATUS_INVALID_IE) instead. This caused AP SME-in-driver cases
returning incorrect status code when the AP did not have a matching
PMKSA cache entry. This could result in unexpected station behavior
where the station could continue trying to use a PMKSA cache entry that
the AP does not have and not being able to recover this.
Fix this by adding the previously missed mapping of validation errors to
status/reason codes.

If hostapd had existing STA SAE state, e.g., from a previously completed
SAE authentication, a new start of a separate SAE authentication (i.e.,
receiving of a new SAE commit) ended up using some of the previous
state. This is problematic for determining whether to H2E vs. looping
since the STA is allowed (even if not really expected to) to change
between these two alternatives. This could result in trying to use H2E
when STA was using looping to derive PWE and that would result in SAE
confirm failing.
Fix this by determining whether to use H2E or looping for the restarted
authentication based on the Status Code in the new SAE commit message
instead of previously cached state information.

IEEE P802.11ay defines Enhanced Directional Multi-Gigabit (EDMG) STA and
AP which allow channel bonding of 2 channels and more.
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.
This implementation is limited to CB2 (channel bonding of 2 channels)

Linux 2.6.32 (December 2009) introduced alternate netlink messages
for setting and installing keys, deprecating the older ones.
To allow hostapd/wpa_supplicant to use new features only provided via
the new API this patch migrates all netlink messages to the current ones.
Since the nl80211 driver was sometimes already using the new format this
is only unifying the netlink API usage and not changing the minimal
kernel requirement.
The following netlink attributes have been retired for key installs:
NL80211_ATTR_KEY_DATA
NL80211_ATTR_KEY_TYPE
NL80211_ATTR_KEY_SEQ
NL80211_ATTR_KEY_IDX
NL80211_ATTR_KEY_CIPHER
NL80211_ATTR_KEY_DEFAULT
NL80211_ATTR_KEY_DEFAULT_MGMT
NL80211_ATTR_KEY_DEFAULT_TYPES
And replaced by the following attributes nested in NL80211_ATTR_KEY:
NL80211_KEY_DATA
NL80211_KEY_TYPE
NL80211_KEY_SEQ
NL80211_KEY_IDX
NL80211_KEY_CIPHER
NL80211_KEY_DEFAULT
NL80211_KEY_DEFAULT_MGMT
NL80211_KEY_DEFAULT_TYPES

sequence number the kernel continues to use the old attributes:

When we set "channel=0" in hostapd.conf to enable ACS function, and set
a wrong channel list, e.g., chanlist=222-999 on purpose, hostapd would
still start ACS process to compute the ideal channel, even when there
are no available channels with such configuration.
Though there is no problem since hostapd fails to initialize interface,
it spends time going through the scan and the debug log entries may make
it more difficult to tell what was behind the failure.
Thus, check if there are any available channels in acs_request_scan(),
and return -1 if no available channel, then it will fail at acs_init(),
without doing ACS computation. It will show the following in the log:
Could not select hw_mode and channel. (-3)
wlan0: interface state UNINITIALIZED->DISABLED
Then we can know the setting is incorrect already in
hostapd_select_hw_mode(), instead of waiting for scan callback function
to know if the setting is ok for ACS or not. This can save time and help
to tell if the setting is correct at the initial function at the first.
This will also allow the ENABLE control interface command to return FAIL
when adding an interface dynamically.

Indication element in the Association Request frame when connecting to
the open OSU BSS, some station devices seem to do so. With the strict

This commit alone does not change actual EAP peer method behavior as

IEEE Std 802.11-2016 is not exactly clear on the encoding of the bit
string that is needed for KCK, PMK, and PMKID derivation, but it seems
to make most sense to encode the (commit-scalar + peer-commit-scalar)
mod r part as a bit string by zero padding it from left to the length of
the order (in full octets).
The previous implementation used the length of the prime (in full
octets). This would work for KCK/PMK, but this results in deriving all
zero PMKIDs for the groups where the size of the order is smaller than
the size of the prime. This is the case for groups 22, 23, and 24.
However, those groups have been marked as being unsuitable for use with
SAE, so this fix should not really have a practical impact anymore.
Anyway, better fix it and document this clearly in the implementation
taken into account the unclarity of the standard in this area.

Previously, check for local MI,MN in a peer's Peers List accepted only

Handling of the optional pathLenConstraint after cA was not done
properly. The position after cA needs to be compared to the end of the
SEQUENCE, not the end of the available buffer, to determine whether the
optional pathLenConstraint is present. In addition, when parsing
pathLenConstraint, the length of the remaining buffer was calculated
incorrectly by not subtracting the length of the header fields needed
for cA. This could result in reading couple of octets beyond the end of
the buffer before rejecting the ASN.1 data as invalid.

might be some exceptions which require ETSI countries to follow

IEEE Std 802.11ai-2016 requires the FILS STA to do this check, but this
was missing from the initial implementation. The AP side behavior was
not described properly in 802.11ai due to a missing change in the
(Re)Association Response frame format tables which has resulted in some
deployed devices not including the RSNE.
For now, use an interoperability workaround to ignore the missing RSNE
and only check the payload of the element if it is present in the
protected frame. In other words, enforce this validation step only with
an AP that implements FILS authentication as described in REVmd while
allowing older implementations to skip this check (and the protection
against downgrade attacks). This workaround may be removed in the future
if it is determined that most deployed APs can be upgraded to add RSNE

Add a QCA vendor sub command QCA_NL80211_VENDOR_SUBCMD_BEACON_REPORTING
to implement beacon reporting feature. Different operations required to
implement this feature can be specified in
QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_OP_TYPE.
Userspace requests the driver/firmware to periodically report received
Beacon frames whose BSSID matches the current connected BSS's MAC
address. If userspace requests the driver/firmware to send beacon
reports actively, the driver encapsulates the details of the beacon in
an event and sends it to userspace asynchronously. Otherwise, the driver
will only update the beacon in cfg80211 scan cache but will not send any
event to userspace.
If this command is not issued, the current behavior of the
driver/firmware is to update the cfg80211 scan cache only when there is
a scan issued by the host in progress or whenever there is a change in
IEs of the Beacon frames from the current connected BSS.
The userspace requests the driver/firmware to stop reporting beacons
when reporting is not required anymore. If the driver/firmware is not
able to receive Beacon frames because of other Wi-Fi operations such as
off-channel activities, etc., the driver/firmware sends a pause event to
userspace and stops reporting Beacon frames. The driver/firmware
indicates whether the beacon reporting automatically resumes later by
using the QCA_WLAN_VENDOR_ATTR_BEACON_REPORTING_AUTO_RESUMES flag. If
userspace doesn't want the beacon reporting to be resumed automatically,
userspace can send QCA_WLAN_VENDOR_BEACON_REPORTING_OP_STOP command to
the driver to stop beacon reporting.

This adds support to hostapd for configuring airtime policy settings for
stations as they connect to the access point. This is the userspace
component of the airtime policy enforcement system PoliFi described in
this paper: https://arxiv.org/abs/1902.03439
The Linux kernel part has been merged into mac80211 for the 5.1 dev
cycle.
The configuration mechanism has three modes: Static, dynamic and limit.
In static mode, weights can be set in the configuration file for
individual MAC addresses, which will be applied when the configured
stations connect.
In dynamic mode, weights are instead set per BSS, which will be scaled
by the number of active stations on that BSS, achieving the desired
aggregate weighing between the configured BSSes. Limit mode works like
dynamic mode, except that any BSS *not* marked as 'limited' is allowed
to exceed its configured share if a per-station fairness share would
assign more airtime to that BSS. See the paper for details on these
modes.

start/stop operations with various parameters (both valid and invalid),
better prevent a crash here by ignoring the unexpected event instead of
trying to process it.

Unexpected CHAN_SWITCH command could get this function using a NULL
pointer if the channel switch was requested while the interface was
already disabled.

driver->hapd_deinit() is going to free the memory that the cached
pointers are pointing to, so clear the pointers to avoid possibility of
dereferencing used memory. It seemed to be possible to hit a code path
using those fields by issuing a CHAN_SWITCH command on disabled hostapd
interface in some cases.

This adds a ieee80211ax=0/1 line to the STATUS output to indicate
the configuration of ieee80211ax, which similar to ieee80211n and
ieee80211ac.

The first four octets of the element were used as a host byte order u32.
That is not correct on bigendian CPUs, so handle byte swapping needs
properly. Mark the he_oper_params field as le32 to explicitly indicate
the byte order and swap the generated params content based on CPU byte
order.

The current code will always use the size required when all optional
elements are present. This will cause the Linux kernel to consider the
field to be malformed if the elements are not actually flagged as being
present.
