de08fae66a DPP: Do not require dpp_configurator_params to start with a space
This ugly hack for being able to search for optional arguments with
space before them was quite inconvenient and unexpected. Clean this up
by handling this mess internally with a memory allocation and string
duplication if needed so that the users of wpa_supplicant control
interface do not need to care about such details.

23dc196fde Check for FT support when selecting FT suites
A driver supports FT if it either supports SME or the
NL80211_CMD_UPDATE_FT_IES command. When selecting AKM suites,
wpa_supplicant currently doesn't take into account whether or not either
of those conditions are met. This can cause association failures, e.g.,
when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
the driver doesn't support it). This change allows an FT suite to be
selected only when the driver also supports FT.

The new sae_pwe=3 mode can be used to test non-compliant behavior with

1ba4a10a07 DPP: Initialize conf_resp_status to non-OK
This avoids unexpected behavior if GAS query fails and the Config
Response does not get processed at all. Previously, this could result in
configuration being assumed to be successful instead of failure when

18714af2d8 DPP: Ignore unexpected duplicated Authentication Confirm
Previously, unexpected Authentication Confirm messages were ignored in
cases where no Authentication Confirm message was expected at all, but
if this message was received twice in a state where it was expected, the
duplicated version was also processed. This resulted in unexpected
behavior when authentication result was processed multiple times (e.g.,
two instances of GAS client could have been started).

Fix this by checking auth->waiting_auth_conf before processing
Authetication Confirm. That boolean was already tracked, but it was used
only for other purposes.

8f8473cebb SAE: Fix peer-commit-scalar reuse check
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.

4bf78a79d0 ACS: Populate channel config from external ACS per documented behavior
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.

a919a26035 Introduce and add key_flag
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.

This commit is not changing any functionality. It just adds the new
key_flag to all hostapd/wpa_supplicant set_key() functions without using
it, yet.

8759e9116a nl80211: Control port over nl80211 helpers
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.

22319c7fed RADIUS client: fix extra retry before failover
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.

4834c6869d FT: Fix hostapd_wpa_auth_oui_iter() iteration for multicast packets
When using FT wildcard feature, the inter-AP protocol will send
broadcast messages to discover related APs.

For example,
12/6 16:24:43 FT: Send PMK-R1 pull request to remote R0KH address
    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.

ef48f1bfb3 Ensure authenticator session timer is applied with wired driver
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.

8e111157e7 nl80211: Relax bridge setup
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.

3626e72c8d l2_packet: Fix bridge workaround for repeater configuration
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.

4cfa8b92ba Fix wpa_insert_pmkid() when buffer includes extra IEs
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.

openssl engines may dynamically load external libraries. Our event_*()
functions happen to be named very generically, such that event_add()

Resolve this by providing a more unique prefix to these functions.

e780b4bf20 DPP: Bootstrapping via NFC URI Record
This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.

The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.

A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.

Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC
URI in the same way as they are used for QR Code.

5b50265e13 WMM: Do not modify input TSPEC buffer during processing
The WMM TSPEC processor used the input buffer for processing the request
and building the response. This was fine for the FT case, but for the
WMM Action frame case, the input buffer is marked const, so it should
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.

f3c077929f P2P: Fix listen state machine getting stuck in send_action() scheduled case
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.

93ba13bcfd Fix status code in SAE/DPP association PMKID mismatch (driver-AP-SME)
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.

93a1e275a7 SAE: Determine H2E vs. looping when restarting SAE auth in AP mode
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.

dda5d9e315 nl80211: Add support for EDMG channels
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)
and the bonded channels must be adjacent.

83b83b461d nl80211: Migrate to current netlink key message format
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
sequence number the kernel continues to use the old attributes:
  NL80211_ATTR_KEY_TYPE
  NL80211_ATTR_KEY_SEQ
  NL80211_ATTR_KEY_IDX

Besides a confusing debug message this does not have any negative side

then it's not used.

With this patch PTKINITNEGOTIATING sets the PTK keyid unconditionally to

d9286d0997 ACS: Stop before scan if no channels in chanlist are available
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

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
report is received from the Enrollee, the event with "timeout" argument
is generated locally.

the recommended practice were included. The main item of some real use
long time ago was the Layer 2 Update frame to update bridges when a STA
roams within an ESS, but that functionality has, in practice, been moved
to kernel drivers to provide better integration with the networking

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.

Note: If both channel and frequency attributes are present in vendor

29ef1c5ee4 DPP: Use a common helper function for ECDH operations
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

ac734a342e SAE: Fix KCK, PMK, and PMKID derivation for groups 22, 23, 24
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.

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.

1e5ea68d1f mka: Accept last two used MNs in Peers List of a received MKPDU
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.

Make the EAP-pwd peer use same default set of allowed groups as the SAE
implementation in wpa_supplicant uses, i.e., the groups 19-21 using NIST

supported by the crypto library were allowed. In practice, this change
disables use of the Brainpool curves (groups 28-30) with recent OpenSSL

The default set of groups can be overridden with a new phase1 network
profile parameter, eap_pwd_groups=<list of allowed ranges>. For example,
phase1="eap_pwd_groups=0-65535" would restore previous behavior of
allowing all implemented groups to be used while eap_pwd_groups=19,20

only the in-tunnel distribution of PAC-Opaque is supported for now. Use

29d8bd1dec nl80211: Add driver multi iftype HE capability parsing
The HE capabilities are no longer per PHY but per iftype on this

capabilities.

The he_capabilities are now duplicated to store all information for
IEEE80211_MODE_* which hostap cares about. The nl80211 driver fills in
this information when the iftype supports HE. The rest of the code still
only uses the IEEE80211_HE_AP portion but can be extended later to also
use other HE capabilities.

Handling of the optional pathLenConstraint after cA was not done
properly. The position after cA needs to be compared to the end of 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.

ef60f0121f hostapd: Process OWE IE and update DH IE to the driver if needed
This implements the required functionality in hostapd to facilitate OWE
connection with the AP SME-in-driver cases. Stations can either send DH
IE or PMKID (in RSNE) (or both) in Association Request frame during the
OWE handshake. The drivers that use this offload mechanism do not
interpret this information and instead, pass the same to hostapd for
further processing. hostapd will either validate the PMKID obtained from
the STA or generate DH IE and further indicate the same to the driver.
The driver further sends this information in the Association Response

636c02c6e9 nl80211: Add regulatory wmm_limit to hostapd_channel_data
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
WMM parameters.

This commit adds determination of regulator limitations to
NL80211_CMD_GET_WIPHY processing so that the information is available
for upper layer implementation to use later when constructing WMM
element.

This is wrong at least for AP mode, the frequency we store
for this case internally in nl80211 should only be updated
when the channel switch completes, otherwise we end up in
a situation where the switch is aborted and the kernel is
thus on the old channel, but the internal information has

31bc66e4d1 More forceful clearing of stack memory with keys
gcc 8.3.0 was apparently clever enough to optimize away the previously
used os_memset() to explicitly clear a stack buffer that contains keys
when that clearing happened just before returning from the function.
Since memset_s() is not exactly portable (or commonly available yet..),
use a less robust mechanism that is still pretty likely to prevent
current compilers from optimizing the explicit clearing of the memory
away.

b1aee7a622 DPP: Fix bootstrapping URI parser to handle channel list for an opclass
The bootstrapping URI format for DPP was extended during protocol design
to allow a list of channels without having to repeat the same operating
class information for each channel. That change was not included in the
initial implementation of the parser and a channel-list like
"C:81/1,6,11" would not be understood correctly (i.e., only the longer
"C:81/1,81/6,81/11" form would have been parsed correctly).

Fix this by extending the parser to accept both the shorter and longer
form for a list of channels within a single operating class.

69afb6b395 FILS: Verify RSNE match between Beacon/Probe Response and (Re)AssocResp
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
into the (Re)Association Response frames.

implementation to match that. Without this, a FILS STA might reject

ae21cffb2c Add QCA vendor command to support beacon reporting feature
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.

ef7217518b hostapd: Add airtime policy configuration support
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.

It should not really be possible to trigger a channel switch during ACS
is running (i.e., before the AP mode operation has been started), but
since that has been seen in an arbitrary test sequence with interface
start/stop operations with various parameters (both valid and invalid),
better prevent a crash here by ignoring the unexpected event instead of

the IGTK KDE uses swapped bytes in the KeyID field (0x0400 and 0x0500
instead of 4 and 5). Such APs cannot be trusted to implement BIP
correctly or provide a valid IGTK, so do not try to configure this key
with swapped KeyID bytes. Instead, continue without configuring the IGTK
so that the driver can drop any received group-addressed robust
management frames due to missing keys.

Normally, this error behavior would result in us disconnecting, but
there are number of deployed APs with this broken behavior, so as an

8b093db2c3 EAP-pwd: Remove unused checks for cofactor > 1 cases
None of the ECC groups supported in the implementation had a cofactor
greater than 1, so these checks are unreachable and for all cases, the
cofactor is known to be 1. Furthermore, RFC 5931 explicitly disallow use
of ECC groups with cofactor larger than 1, so this checks cannot be
needed for any curve that is compliant with the RFC.

prevents reflection attacks where the adversary reflects the scalar and

The vulnerability allows an adversary to complete the EAP-pwd handshake

result, this cannot be abused to bypass authentication unless EAP-pwd is
used in non-WLAN cases without any following key exchange that would

90839597cc SAE: Mask timing of MODP groups 22, 23, 24
These groups have significant probability of coming up with pwd-value
that is equal or greater than the prime and as such, need for going
through the PWE derivation loop multiple times. This can result in
sufficient timing different to allow an external observer to determine
how many rounds are needed and that can leak information about the used
password.

Force at least 40 loop rounds for these MODP groups similarly to the ECC
group design to mask timing. This behavior is not described in IEEE Std
802.11-2016 for SAE, but it does not result in different values (i.e.,
only different timing), so such implementation specific countermeasures
can be done without breaking interoperability with other implementation.

Note: These MODP groups 22, 23, and 24 are not considered sufficiently
strong to be used with SAE (or more or less anything else). As such,
they should never be enabled in runtime configuration for any production
use cases. These changes to introduce additional protection to mask
timing is only for completeness of implementation and not an indication
that these groups should be used.

aaf65feac6 EAP-pwd: Use constant time and memory access for finding the PWE
This algorithm could leak information to external observers in form of
timing differences or memory access patterns (cache use). While the
previous implementation had protection against the most visible timing
differences (looping 40 rounds and masking the legendre operation), it
did not protect against memory access patterns between the two possible
code paths in the masking operations. That might be sufficient to allow
an unprivileged process running on the same device to be able to
determine which path is being executed through a cache attack and based
on that, determine information about the used password.

Convert the PWE finding loop to use constant time functions and
identical memory access path without different branches for the QR/QNR
cases to minimize possible side-channel information similarly to the
changes done for SAE authentication. (CVE-2019-9495)

This helps in reducing measurable timing differences in operations
involving private information. BoringSSL has removed BN_FLG_CONSTTIME
and expects specific constant time functions to be called instead, so a
bit different approach is needed depending on which library is used.

The main operation that needs protection against side channel attacks is
BN_mod_exp() that depends on private keys (the public key validation
step in crypto_dh_derive_secret() is an exception that can use the
faster version since it does not depend on private keys).

crypto_bignum_div() is currently used only in SAE FFC case with not
safe-prime groups and only with values that do not depend on private
keys, so it is not critical to protect it.

crypto_bignum_inverse() is currently used only in SAE FFC PWE
derivation. The additional protection here is targeting only OpenSSL.
BoringSSL may need conversion to using BN_mod_inverse_blinded().

2ffd8076de FT/RRB: Pad RRB messages to at least minimum Ethernet frame length
Ethernet frames have minimum length of 64 octets and shorter frames may
end up getting arbitrary padding in the end. This would result in the
FT/RRB receiver rejecting the frame as an incorrectly protected one.
Work around this by padding the message so that it is never shorter than
the minimum Ethernet frame.

Unfortunately, this padding is apparently not enough with all Ethernet
devices and it is still possible to see extra two octet padding at the
end of the message even if larger frames are used (e.g., showed up with
128 byte frames). For now, work around this by trying to do AES-SIV

b750dde64d OWE: Move Association Response frame IE addition to appropriate place
This code was after the FILS handling that would have encrypted the
frame. While FILS and OWE are never used together, the OWE handling
should really be before the FILS handling since no IEs can be added
after the FILS encryption step. In addition, the Diffie-Hellman
Parameter element is not a Vendor Specific element, so it should be
before some of the Vendor Specific elements even though it is not
defined in IEEE 802.11.

10ec6a5f38 DPP2: PFS for PTK derivation
Use Diffie-Hellman key exchange to derivate additional material for
PMK-to-PTK derivation to get PFS. The Diffie-Hellman Parameter element
(defined in OWE RFC 8110) is used in association frames to exchange the
DH public keys. For backwards compatibility, ignore missing
request/response DH parameter and fall back to no PFS in such cases.

The previous OWE implementation on the AP side rejected any

if AKM was not OWE. This breaks compatibility with DPP PFS, so relax
that rule to allow DPP AKM to be used as well. While this commit alone

ff5f54e159 SAE: Reduce queue wait time for pending Authentication frames
The queue_len * 50 ms wait time was too large with the retransmission
timeouts used in the mesh case for SAE. The maximum wait of 750 ms was
enough to prevent successful completion of authentication after having
hit the maximum queue length. While the previous commit is enough to
allow this to complete successfully in couple of retries, it looks like
a smaller wait time should be used here even if it means potentially
using more CPU.

Drop the processing wait time to queue_len * 10 ms so that the maximum
wait time is 150 ms if the queue is full.

5e3a759cd4 SAE: Improved queuing policy for pending authentication frames
The previous design of simply queuing all SAE commit messages was not
exactly good at allowing recovery from a flooding state if the valid
peer used frequent retransmissions of the SAE message. This could
happen, e.g., with mesh BSSs using SAE. The frequent retransmissions and
restarts of SAE authentication combined with SAE confirm messages
bypassing the queue ended up in not being able to finish SAE exchange
successfully.

Fix this by modifying the queuing policy to queue SAE confirm messages
if there is a queued SAE commit message from the same peer so that the
messages within the same exchange do not get reordered. In addition,
replace queued SAE commit/confirm message if a new matching message is
received from the same peer STA. This is useful for the case where the
peer restarts SAE more quickly than the local end has time to process
the queued messages.

including the parameter. Map the -1 value to a driver request to disable
the threshold. Ignore any error from this operation just in case to

4d379be4a9 Clarify AP mode Action frame handling
Include only one of hostapd_mgmt_rx() and hostapd_action_rx() functions
in the build. Previously, NEED_AP_MLME builds (i.e., cases where hostapd
AP MLME implementation is included) included both of these functions and
both were tried in sequence. In addition to being difficult to
understand, that could result in unexpected behavior if
hostapd_mgmt_rx() rejected a frame and return 0 to allow
hostapd_action_rx() to attempt to process the frame.

All the operations included in hostapd_action_rx() are supposed to be
available through the hostapd_mgmt_rx() call in handle_action() and
those should result in the exact same Category/Action-based handler
function to be called in the end. As such, this should not result in
different behavior. And if there is a difference, that would be pointing
at a hidden bug that would need to be fixed anyway. Furthermore, builds
without NEED_AP_MLME would not have any difference in behavior or

002edb6303 Fix AP MLME in driver handling of FT and SA Query Action frames
hostapd_action_rx() was pointing at incorrect field (Action vs.
Category) for the wpa_ft_action_rx() call and the length check for SA
Query Action frames. This resulted in those frames getting dropped as
invalid (FT) or ignored as truncated (SA Query). Fix this by pointing to
the correct place at the beginning of the frame body.

This issue had a long history. These were broken during cleanup in
commit dbfb8e82ff ("Remove unnecessary EVENT_RX_ACTION") which
actually fixed the initial reason for the error accidentally. It was
just that that error was needed to cancel out another earlier error..

One of the errors came from misuse of the EVENT_RX_ACTION API in commit
deca6eff74 ("atheros: Add new IEEE 802.11r driver_ops"). That pointed
struct rx_action data/len to cover the Action frame from the Category
field to the end of the frame body while the API was documented to cover
Action field to the end of the frame body. This error was cancelled by
another error in commit 88b32a99d3 ("FT: Add FT AP support for drivers
that manage MLME internally") that called wpa_ft_action_rx() with the
struct rx_action::data field as the second argument. That argument needs
to point to the Category field, but that struct rx_action field was
supposed to point to the Action field.

Number of the Action frame handlers added into hostapd_action_rx() had
been fixed more or less accidentally after this in various other
commits, but the FT and SA Query handlers had ended up maintaining the
incorrect operations. This is now fixing those.

This seems to fix at least some cases of FT-over-DS with drivers that
use driver-based AP MLME. Such drivers might use internal SA Query
processing, so it is not clear whether that part actually fixes any real
issues.

96d6dfa8e4 SAE: Add Finite Cyclic Group field in status code 77 response
Copy the Finite Cyclic Group field value from the request to the
response Authentication frame if we end up rejecting the request due to
unsupported group.

IEEE Std 802.11-2016 has conflicting statements about this behavior.
Table 9-36 (Presence of fields and elements in Authentication frames)
indicates that the Finite Cyclic Group field is only included with
status code values 0 (success) and 76 (anti-clogging token request)
while SAE protocol description implying that the Finite Cyclic Group
field is set to the rejected group (12.4.8.6.3 and 12.4.8.6.4).

The standard language needs to cleaned up to describe this
unambiguously, but since it looks safe to add the field into the
rejection case and since there is desire to have the field present to be
able to implement what exactly is stated in 12.4.8.6.4, it looks
reasonable to move ahead with the AP mode implementation change. There
is no change in wpa_supplicant for now to modify its behavior based on
whether this field is present, i.e., wpa_supplicant will continue to
work with both the old and new hostapd behavior for SAE group
negotiation.

a9af1da0b5 SAE: Enforce single use for anti-clogging tokens
Add a 16-bit token index into the anti-clogging token. This can be used
to enforce only a single use of each issued anti-clogging token request.
The token value is now token-index |
last-30-octets-of(HMAC-SHA256(sae_token_key, STA-MAC-address |
token-index)), i.e., the first two octets of the SHA256 hash value are
replaced with the token-index and token-index itself is protected as
part of the HMAC context data.

Track the used 16-bit token index values and accept received tokens only
if they use an index value that has been requested, but has not yet been
used. This makes it a bit more difficult for an attacker to perform DoS
attacks against the heavy CPU operations needed for processing SAE
commit since the attacker cannot simply replay the same frame multiple
times and instead, needs to request each token separately.

While this does not add significant extra processing/CPU need for the
attacker, this can be helpful in combination with the queued processing
of SAE commit messages in enforcing more delay during flooding of SAE
commit messages since the new anti-clogging token values are not
returned before the new message goes through the processing queue.

ff9f40aee1 SAE: Process received commit message through a queue
This allows better control of processing new SAE sessions so that other
operations can be given higher priority during bursts of SAE requests,
e.g., during a potential DoS attack. The receive commit messages are
queued (up to maximum of 15 entries) and processed from eloop callback.
If the queue has multiple pending entries, more wait time is used to go
through the each new entry to reduce heavy CPU load from SAE processing.

941bad5ef4 SAE: Enable only group 19 by default in AP mode
Change the AP mode default for SAE to enable only the group 19 instead
of enabling all ECC groups that are supported by the used crypto library
and the SAE implementations. The main reason for this is to avoid
enabling groups that are not as strong as the mandatory-to-support group
19 (i.e., groups 25 and 26). In addition, this disables heavier groups
by default.

In addition, add a warning about MODP groups 1, 2, 5, 22, 23, and 24
based on "MUST NOT" or "SHOULD NOT" categorization in RFC 8247. All the
MODP groups were already disabled by default and would have needed
explicit configuration to be allowed.

2c129a1b71 Fix cipher suite selector default value in RSNE for DMG
According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).

It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.

In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

66819b07b5 hostapd: Support Multi-AP backhaul STA onboarding with WPS
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the WPS Registrar offers a
different set of credentials (backhaul credentials instead of fronthaul
credentials) when the Multi-AP subelement is present in the WFA vendor
extension element of the WSC M1 message.

Add new configuration options to specify the backhaul credentials for
the hostapd internal registrar: multi_ap_backhaul_ssid,
multi_ap_backhaul_wpa_psk, multi_ap_backhaul_wpa_passphrase. These are
only relevant for a fronthaul SSID, i.e., where multi_ap is set to 2 or
3. When these options are set, pass the backhaul credentials instead of
the normal credentials when the Multi-AP subelement is present.

Ignore the Multi-AP subelement if the backhaul config options are not
set. Note that for an SSID which is fronthaul and backhaul at the same
time (i.e., multi_ap == 3), this results in the correct credentials
being sent anyway.

The security to be used for the backaul BSS is fixed to WPA2PSK. The
Multi-AP Specification only allows Open and WPA2PSK networks to be
configured. Although not stated explicitly, the backhaul link is
intended to be always encrypted, hence WPA2PSK.

To build the credentials, the credential-building code is essentially
copied and simplified. Indeed, the backhaul credentials are always
WPA2PSK and never use per-device PSK. All the options set for the
fronthaul BSS WPS are simply ignored.

83ebf55865 wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS
The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).

Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.

Only wps_pbc is supported.

This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.

Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

MULTI_AP_SUB_ELEM_TYPE definition here, but rather define a new

bfcdac1c8b Multi-AP: Don't reject backhaul STA on fronthaul BSS
The Multi-AP specification only specifies that information elements have
to be added to the Association Request and Association Response frame;
it doesn't specify anything about what should be done in case they are
missing. Previously, we rejected non-backhaul associations on a
backhaul-only BSS, and non-fronthaul associations on a fronthaul-only
BSS.

However, this makes WPS fail when fronthaul and backhaul are separate
SSIDs. Indeed, WPS for the backhaul link is performed on the *fronthaul*
SSID. Thus, the Association Request frmae used for WPS *will* contain
the Multi-AP IE indicating a backhaul STA. Rejecting that association
makes WPS fail.

Therefore, accept a multi-AP backhaul STA Association Request frame on a
fronthaul-only BSS. Still issue a warning about it, but only at level
DEBUG intead of INFO. Also change the condition checking to make it
clearer.

While we're at it, also fix the handling of unexpected bits in the
Multi-AP IE. 4 bits are reserved in the specification, so these
certainly have to be ignored. The specification also doesn't say that
setting one of the other bits is not allowed. Therefore, only report
unexpected values in the Multi-AP IE, don't reject because of it. Note
that a malformed IE (containing more than one byte) still triggers a
rejection.

f2a6ac63ee P2P: Update find_start timer only when p2p_scan is started.
p2p->find_start timer was updated on each p2p_find call irrespective of
p2p_find being successful/failed/rejected. For cases where p2p_find was
in progress/pending, another call to p2p_find would be rejected but
p2p->find_start timer would still be updated.

p2p->find_start is maintained in wpa_supplicant to reject the kernel
scan entries before the p2p->find_start time. In above scenario, some of
the scan entries could be discarded even if the Probe Respons frame(s)
were received during the last scan/p2p_find.

This commit changes this to update the p2p->find_start timer only when

e34cd9f06e WNM: Fix WNM-Sleep Mode Request bounds checking
ieee802_11_rx_wnmsleep_req() might have been called for a short frame
that has no more payload after the Public Action field, i.e., with len
== 0. The bounds checking for the payload length was done only for the
information elements while the one octet Dialog Token field was read
unconditionally. In the original implementation, this could have
resulted in reading one octet beyond the end of the received frame data.

This case has not been reachable after the commit e0785ebbbd ("Use
more consistent Action frame RX handling in both AP mode paths"), but it
is better to address the specific issue in ieee802_11_rx_wnmsleep_req()
as well for additional protection against accidential removal of the
check and also to have something that can be merged into an older
version (pre-v2.7) if desired. The comments below apply for such older
versions where the case could have been reachable.

Depending on driver interface specific mechanism used for fetching the
frame, this could result in reading one octet beyond the end of a
stack/hash buffer or reading an uninitialized octet from within a
buffer. The actual value that was read as the Dialog Token field is not
used since the function returns immediately after having read this value
when there is no information elements following the field.

This issue was initially added in commit d32d94dbf4 ("WNM: Add
WNM-Sleep Mode implementation for AP") (with CONFIG_IEEE80211V=y build
option) and it remained in place during number of cleanup and fix
changes in this area and renaming of the build parameter to
CONFIG_WNM=y. The impacted function was not included in any default
build without one of the these optional build options being explicitly
enabled. CONFIG_WNM=y is still documented as "experimental and not
complete implementation" in hostapd/defconfig. In addition, commit
114f2830d2 ("WNM: Ignore WNM-Sleep Mode Request in wnm_sleep_mode=0
case") made this function exit before the impact read if WNM-Sleep Mode
support was not explicitly enabled in runtime configuration
(wnm_sleep_mode=1 in hostapd.conf). Commit e0785ebbbd ("Use more
consistent Action frame RX handling in both AP mode paths") made this
code unreachable in practice.

Add an explicit check that the frame has enough payload before reading
the Dialog Token field in ieee802_11_rx_wnmsleep_req().

to carry the list of avoid frequencies that aim to avoid any

strictly by trying to prevent WLAN traffic on the impacted channels.

This commit refines the expectation of the interface by defining this
avoid channel list to allow minimal traffic but not heavier one. For
example, P2P may still be able to use avoid list frequencies for P2P
discovery and GO negotiation if the actual group can be set up on a not

27ebadccfb RADIUS client: Cease endless retry for message for multiple servers
In the previous RADIUS client implementation, when there are multiple
RADIUS servers, we kept trying the next server when the current message
can not be acked. It leads to endless retry when all the RADIUS servers
are down.

Fix this by keeping a counter for the accumulated retransmit attempts
for the message, and guarantee that after all the servers failover
RADIUS_CLIENT_MAX_FAILOVER times the message will be dropped.

Another issue with the previous code was that the decision regarding
whether the server should fail over was made immediately after we send
out the message. This patch guarantees we consider whether a server
needs failover after pending ack times out.

b686745c76 Android: Harden wpa_ctrl_open2() against potential race conditions
The Android-specific chmod and chown operations on the client socket
(for communication with wpa_supplicant) did not protect against file
replacement between the bind() and chmod()/chown() calls. If the
directory in which the client socket is created (depends a bit on the
version and platform, but /data/misc/wifi/sockets is commonly used)
allows write access to processes that are different (less privileged)
compared to the process calling wpa_ctrl_open2(), it might be possible
to delete the socket file and replace it with something else (mainly, a
symlink) before the chmod/chown operations occur. This could have
resulted in the owner or permissions of the target of that symlink being
modified.

In general, it would be safest to use a directory which has more limited
write privileges (/data/misc/wifi/sockets normally has 'wifi' group
(AID_WIFI) with write access), but if that cannot be easily changed due
to other constraints, it is better to make wpa_ctrl_open2() less likely
to enable this type of race condition between the operations.

Replace chown() with lchown() (i.e., a version that does not dereference
symlinks) and chmod() with fchmod() on the socket before the bind() call
which is also not going to dereference a symlink (whereas chmod()
would). lchown() is a standard operation, but the fchmod() on the socket
is less so (unspecified behavior in some systems). However, it seems to
work on Linux and in particular, on Android, where this code is
executed.

driver/hardware can declare more strict limitations than declared in the
IEEE 802.11 standard. Without this patch hostapd might select
unsupported channel and that will fail because Linux kernel does check
channel bandwidth limitations.

cc9c4feccc OpenSSL: Allow systemwide policies to be overridden
Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.

Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.

In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.

In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

4cf5efece3 FT: Allow STA entry to be removed/re-added with FT-over-the-DS
FT-over-the-DS has a special case where the STA entry (and as such, the
TK) has not yet been configured to the driver depending on which driver
interface is used. For that case, allow add-STA operation to be used
(instead of set-STA). This is needed to allow mac80211-based drivers to
accept the STA parameter configuration. Since this is after a new
FT-over-DS exchange, a new TK has been derived after the last STA entry
was added to the driver, so key reinstallation is not a concern for this
case.

ba4f3224ae Allow remote RADIUS authentication with local VLAN management
The documentation in the hostapd.conf file says that the dynamic_vlan
variable is used to control whether VLAN assignments are accepted from a
RADIUS server. The implication seems to be that a static VLAN assignment
will come from the accept_mac_file if dynamic_vlan is set to 0, and a
dynamic assignment will come from the RADIUS server if dynamic_vlan is
set to 1. Instead, I'm seeing that the static settings from the
accept_mac_file are ignored if dynamic_vlan is set to 0, but used if
dynamic_vlan is set to 1. If dynamic_vlan is set to 1 and the RADIUS
server does not provide a VLAN, then the accept_mac_file assignment is
overridden and the STA is assigned to the default non-VLANed interface.

If my understanding of the expected behavior is correct, then I believe
the problem is in ap_sta_set_vlan(). That routine checks the
dynamic_vlan setting, but has no way of determining whether the incoming
vlan_desc is static (i.e., from accept_mac_file) or dynamic (i.e., from
a RADIUS server).

I've attached a patch that gets hostapd working as I believe it's meant
to, and updates the documentation to make the implicit behavior
explicit.

The functional changes are:

- hostapd_allowed_address() will always extract the vlan_id from the
  accept_macs file. It will not update the vlan_id from the RADIUS cache
  if dynamic_vlan is DISABLED.

- hostapd_acl_recv_radius() will not update the cached vlan_id if
  dynamic_vlan is DISABLED.

- ieee802_1x_receive_auth() will not update the vlan_id if dynamic_vlan
  is DISABLED.

More cosmetic:

Most of the delta is just moving code out of ieee802_1x_receive_auth()
into a new ieee802_1x_update_vlan() routine. While I initially did this
because the new DISABLED check introduced excessive indentation, it has
the added advantage of eliminating the vlan_description allocation and
os_memset() call for all DYNAMIC_VLAN_DISABLED configs.

I've done a couple rounds of review offline with Michael Braun (who has
done much of the work in this part of the code) and incorporated his
feedback.

If dynamic_vlan=0 (disabled), vlan assignments will be managed using the
local accept_mac_file ACL file, even if a RADIUS server is being used
for user authentication. This allows us to manage users and devices
independently.

3ec118780a RRM: Add support for beacon report fragmentation
When the frame body subelement would cause the measurement report
element to exceed the maximum element size, the frame body subelement
used to be truncated. In addition, some elements were always truncated
in order to keep the reported frame body short (e.g. RSN IE).

Alternatively, IEEE P802.11-REVmd/D2.0, 9.4.2.21.7 extension to Beacon
reporting can be used: The frame body subelement is fragmented across
multiple beacon report elements, and the reported frame body fragment ID
subelement is added.

Use beacon report fragmentation instead of truncating the frame body
as this method gives the AP a more complete information about the
reported APs.

89a7cdd690 crypto: Add option to use getrandom()
According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:

"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."

An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.

It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).
