After a radar signal is detected, the AP should switch to another
channel, but in the case of 80+80 MHz, channel switch failed because

The initial implementation of the PTK derivation workaround for
interoperability with older OWE implementations forced
WPA_KEY_MGMT_PSK_SHA256 to be used for all of PTK derivation. While that
is needed for selecting which hash algorithm to use, this was also
changing the length of the PTK components and by doing so, did not
actually address the backwards compatibility issue.
Fix this by forcing SHA256 as the hash algorithm in PTK derivation
without changing the PTK length calculation for OWE when
owe_ptk_workaround is enabled.

Always report an error when NL80211_CMD_SET_KEY can't set a key to
default.
The old ioctl-based design used a single command to add, set, and delete
a key and had to ignore ENOENT for key deletions. It looks like that
special handling was also ported for NL80211_CMD_NEW_KEY and
NL80211_CMD_SET_KEY instead only for NL80211_CMD_DEL_KEY.

Only one peer-commit-scalar value was stored for a specific STA (i.e.,
one per MAC address) and that value got replaced when the next SAE
Authentication exchange was started. This ended up breaking the check
against re-use of peer-commit-scalar from an Accepted instance when
anti-clogging token was requested. The first SAE commit message (the one
without anti-clogging token) ended up overwriting the cached
peer-commit-scalar value while leaving that instance in Accepted state.
The second SAE commit message (with anti-clogging token) added ended up
getting rejected if it used the same value again (and re-use is expected
in this particular case where the value was not used in Accepted
instance).
Fix this by using a separate pointer for storing the peer-commit-scalar
value that was used in an Accepted instance. There is no need to
allocate memory for two values, i.e., it is sufficient to maintain
separate pointers to the value and move the stored value to the special
Accepted state pointer when moving to the Accepted state.
This fixes issues where a peer STA ends up running back-to-back SAE
authentication within couple of seconds, i.e., without hostapd timing
out the STA entry for a case where anti-clogging token is required.

Based on the now documented seg0/seg1 values from offloaded ACS, there
is a mismatch between the driver interface and internal hostapd use.
The value of segment0 field in ACS results is the index of the channel
center frequency for 20 MHz, 40 MHz, and 80M Hz channels. The value is
the center frequency index of the primary 80 MHz segment for 160 MHz and
80+80 MHz channels.
The value of segment1 field in ACS results is zero for 20 MHz, 40 MHz,
and 80 MHz channels. The value is the index of the channel center
frequency for 160 MHz channels and the center frequency index of the
secondary 80 MHz segment for 80+80 MHz channels.
However, in struct hostapd_config, for 160 MHz channels, the value of
the segment0 field is the index of the channel center frequency of 160
MHz channel and the value of the segment1 field is zero. Map the values
from ACS event into hostapd_config fields accordingly.

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

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.

Signed-off-by: Markus Theil <markus.theil@tu-ilmenau.de>
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.

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.

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.

EAP-SIM full authentication starts with one or more SIM/Start rounds, so
reject an unexpected SIM/Challenge round without any preceeding

The WMM TSPEC processor used the input buffer for processing the request

not really be modified. This modification could not really cause any
noticeable harm, but it can result in error reports from fuzzing and
potentially even from some static analyzers.
Fix this by marking the input arguments const more consistently (the
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.

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
When getting Michael MIC failure notifications or querying a key

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.

A new argument to the DPP_AUTH_INIT command (conn_status=1) can now be

connection result after a successfully completed provisioning step. If
the peer supports this, the DPP-CONF-SENT event indicates this with a
new argument (wait_conn_status=1) and the Configurator remains waiting
for the connection result for up to 16 seconds.
Once the Enrollee reports the result, a new DPP-CONN-STATUS-RESULT event
is generated with arguments result, ssid, and channel_list indicating
what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no

be used to test TEAP exchange where the Intermediate-Result TLV and
Crypto-Binding TLV are send in one message exchange while the Result TLV
exchange in done after that in a separate message exchange.
Signed-off-by: Jouni Malinen <j@w1.fi>
If the Crypto-Binding TLV for the last EAP method has been validated
successfully in a previous message exchange with Intermediate-Result TLV
and no new EAP method has been started, Result TLV can be accepted
without an additional Crypto-Binding TLV. This allows the server to go
through additional message exchanges after inner EAP method, if needed.

It is not sufficient for the peer to include only the Result TLV if the
server included both the Intermediate-Result TLV and Result TLV.

Previously, only the Result TLV was added when writing Crypto-Binding
TLV response. This is not sufficient, since RFC 7170 require
Intermediate-Result TLV response to be included from the peer if the
server included Intermediate-Result TLV.

If FT over-the-DS case is enforced through the "FT_DS <BSSID>" control
interface command, the PMF capability check during BSS selection is not
used and that could have allowed PMF to be disabled in the over-the-DS
case even if the local network profile mandated use of PMF. Check
against this explicitly to avoid unexpected cases if the APs within the

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
HT/VHT/none information on 2.4 GHz.

As a part of P802.11ax amendment, 6 GHz band operation is added.
Since the 6 GHz channel numbers are overlapping with existing 2.4 GHz
and 5 GHz channel numbers, use frequency to identify unique channel
operation instead of channel number. Channel frequency is unique across
bands.
In the existing QCA vendor interface, wherever missing, add frequency
attributes to identify unique channel operation. In addition, add
comments to document some of the previously missed attributes/values.
Note: If both channel and frequency attributes are present in vendor
command/event and
(a) If both the driver and user-space application supports 6 GHz band
then channel related attributes are deprecated and use frequency
attributes.
(b) If either driver or user-space application or both doesn't
support 6 GHz band then use channel attributes.

It looks like EVP_PKEY_derive() may change the returned length of the
buffer from the initial length determination (NULL buffer) to the
fetching of the value. Handle this by updating the secret length based
on the second call instead of the first one. This fixes some cases where
ECDH result has been used with extra data (zeros in the end) with OWE or
FILS PFS.
Signed-off-by: Jouni Malinen <j@w1.fi>
This replaces the separately implemented ECDH operations with a single
helper function to avoid code duplication. In addition, this introduces
a workaround for strange OpenSSL behavior where the first
EVP_PKEY_derive(NULL) call to learn the size of the output shared secret
returns unexpectedly large buffer (72 octets when expected 32 octets for
group 19). It is not known what is causing this, but such behavior seems
to be showing up every now and then at least when running hwsim test
cases under UML and apparently mainly (only?) in the sigma_dut
controller cases.

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.

BN_bn2bin_padded() broke this function for cases where no padding is
used (padlen == 0). Those would have always failed after the changes and

hostap.git, so this did not have any real issues, but anyway, better fix
this function to match its documentation.

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.

The relevant flags were only added in Linux 4.6, so we shouldn't
complain because they're missing. Also, they're always missing if a
device is being removed (e.g., 'iw dev wlan0 del', or if the device is
in the process of resetting itself). So kill those 2 birds with 1 stone:
if we can't find the file, just silently skip it.
Also, we probably should *actually* propagate the error if we had a

Previously, check for local MI,MN in a peer's Peers List accepted only
the cases that include the last used MN from an MKPDU sent by the local
device. This was problematic since it was possible to synchronize MKPDU
transmission between two devices in a way that made them always miss the
last MKPDU from the other device before filling in the Peers List.
Relax this matching requirement of "acceptably recent MN" to mean both
the last used MN and the one used just before it (i.e., copied from
either of the last two MKPDUs sent by the local device) are accepted.
While this might help in some real world scenarios in making the
protocol converge more quickly, the main help from this is to fix
consistent hwsim test cases failures in macsec_psk_ns when using UML
with time travel option which happened to practically guarantee the
inconvenient timing of MKPDU transmission/reception that ended up with
the MKPDU processing to see MI,MN with MN being the last used MN minus
1.
