885097125c mesh: Fix peer link counting when removing a mesh peer
When removing a mesh peer with control interface commands (ACCEPT_ACL
DEL_MAC/DENY_ACL ADD_MAC/MESH_PEER_REMOVE) the plink count was not
decreased from its last connection. This resulted in peer link count
leakage and wpa_supplicant rejecting the connections after reaching

d0819a11cc FILS: Use FILS auth alg when connecting using PMKSA caching
When a PMKSA cache entry is available and used for connection with FILS
key management suite, use FILS authentication algorithm for connection
even if ERP keys are not available. This scenario may happen when
applications using wpa_supplicant cache persistently only PMKSA but not
ERP keys and reconfigures wpa_supplicant with PMKSA cache after
restarting wpa_supplicant.

The previous implementation correctly handles SME-in-wpa_supplicant
cases. However, SME-in-driver cases, complete FILS authentication
without PMKSA caching is performed.

Fix SME-in-driver behavior by setting authentication algorithm to
WPA_AUTH_ALG_FILS when connecting to a FILS AP using PMKSA caching.

cc2d03601b HS 2.0: Use global pmf=2 for the created network block
Previously, PMF support was enabled in optional mode (ieee80211w=1) for
Hotspot 2.0 network blocks automatically. This did not consider the
global PMF parameter and unconditionally changed that value to optional.
Since the newly added network block had an explicit ieee80211w
parameter, this overrode the global parameter. To make this less
surprising, use the global pmf parameter value to select whether to add
network blocks for Hotspot 2.0 with PMF being optionally enabled (pmf=0
or pmf=1) or required (pmf=2).

215b4d8a72 FT: Do not add PMKID to the driver for FT-EAP if caching is disabled
wpa_supplicant disables PMKSA caching with FT-EAP by default due to
known interoperability issues with APs. This is allowed only if the
network profile is explicitly enabling caching with
ft_eap_pmksa_caching=1. However, the PMKID for such PMKSA cache entries
was still being configured to the driver and it was possible for the
driver to build an RSNE with the PMKID for SME-in-driver cases. This
could result in hitting the interop issue with some APs.

Fix this by skipping PMKID configuration to the driver fot FT-EAP AKM if
ft_eap_pmksa_caching=1 is not used in the network profile so that the
driver and wpa_supplicant behavior are in sync for this.

0c5edededa DPP: Fix config exchange with gas_rand_mac_addr
Do not use a random MAC address for the GAS exchange that is used as
part of the DPP protocol exchange since that would break DPP.
Configurator expects the same MAC address to be used for DPP
Authentication exchange and DPP Configuration exchange (GAS).

Since the DPP Authentication exchange has already used the MAC address
configured on the interface, use of a random address for the GAS
exchange would not provide any additional privacy protection. If a
random MAC address needs to be used for this type of an exchange, that
random address would need to be first configured on the interface before
starting DPP exchange.

This does not change GAS query behavior for any other use case, i.e.,
the gas_rand_mac_addr configuration continues to apply to all the
Interworking/Hotspot 2.0 uses.

5058f771d9 DPP2: Allow station to require or not allow PFS
The new wpa_supplicant network profile parameter dpp_pfs can be used to
specify how PFS is applied to associations. The default behavior
(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if
the AP supports it. PFS use can now be required (dpp_pfs=1) or disabled
(dpp_pfs=2).

This is also working around an interoperability issue of DPP R2 STA with
certain hostapd builds that included both OWE and DPP functionality.
That issue was introduced by commit 09368515d1 ("OWE: Process
Diffie-Hellman Parameter element in AP mode") and removed by commit
16a4e931f0 ("OWE: Allow Diffie-Hellman Parameter element to be
included with DPP"). hostapd builds between those two commits would
reject DPP association attempt with PFS. The new wpa_supplicant default
(dpp_pfs=0) behavior is to automatically try to connect again with PFS
disabled if that happens.

22f0318dbd Interpolate rate calculation functions
Make max_*_rate() functions and rate calculation at the beginning of
wpas_get_est_tpt() more continuous. In wpa_supplicant_need_to_roam(), we
compare these values to make a roaming decision. However, at certain
SNRs, we see unrealistically large jumps in estimated throughput
according to these functions, leading us to make incorrect roaming
decisions. Perform linear interpolation where applicable to more
accurately reflect actual throughput.

Example:
wlan0: Current BSS: 88:3d:24:b4:95:d2 freq=2412 level=-69 snr=20 est_throughput=54000
wlan0: Selected BSS: 88:3d:24:b4:89:9e freq=2417 level=-67 snr=22 est_throughput=63500
wlan0: Using signal poll values for the current BSS: level=-69 snr=20 est_throughput=54000
wlan0: Allow reassociation - selected BSS has better estimated throughput

2 dB increase in RSSI likely isn't responsible for a 17% increase in
throughput.

ecb5219d8c OWE: Avoid incorrect profile update in transition mode
The "unexpected" change of SSID between the current network profile
(which uses the SSID from the open BSS in OWE transition mode) and the
association with the OWE BSS (which uses a random, hidden SSID) resulted
in wpa_supplicant incorrectly determining that this was a
driver-initiated BSS selection ("Driver-initiated BSS selection changed
the SSID to <the random SSID from OWE BSS>" in debug log).

This ended up with updating security parameters based on the network
profile inwpa_supplicant_set_suites() instead of using the already
discovered information from scan results. In particular, this cleared
the RSN supplicant state machine information of AP RSNE and resulted in
having to fetch the scan results for the current BSS when processing
EAPOL-Key msg 3/4.

Fix this by recognizing the special case for OWE transition mode where
the SSID for the associated AP does not actually match the SSID in the
network profile.

3fadb1dcc0 WPS: Ignore other APs if PBC is used with a specific BSSID
While the WSC specification requires the Enrollee to stop PBC
provisioning if the scan sees multiple APs in active PBC mode, this is
problematic due to some deployed devices continuing to advertise PBC
mode for extended duration (or even permanently). Such an environment
will still need to prevent wildcard AP selection with PBC since an
incorrect device could be selected. However, if the Enrollee device has
been explicitly requested to connect to a specific AP based on its
BSSID, the other APs in scan results can be ignored without affecting
which AP would be selected (only the one matching the specified BSSID is
acceptable).

Start filtering scan results for PBC session overlap check based on the
locally specified constraint on the BSSID, if one is set. This allows
PBC to be used with "WPS_PBC <BSSID>" command in environment where
another AP device is claiming to be in active PBC mode while "WPS_PBC"
command will still continue to reject provisioning since the correct AP
cannot be selected.

This will also cover the P2P cases where P2P_CONNECT is used to start or
authorize GO Negotiation and joining-a-GO with a specific P2P GO
Interface Address (BSSID).

SM Power Save was described in somewhat unclear manner in IEEE Std
802.11n-2009 as far the use of it locally in an AP to save power. That
was clarified in IEEE Std 802.11-2016 to allow only a non-AP STA to use
SMPS while the AP is required to support an associated STA doing so. The
AP itself cannot use SMPS locally and the HT Capability advertisement
for this is not appropriate.

Remove the parts of SMPS support that involve the AP using it locally.
In practice, this reverts the following commits:

75d0ec4702 P2P: Fix a possible buffer overflow in struct p2p_reg_class
Avoid adding more than P2P_MAX_REG_CLASSES operating classes or
P2P_MAX_REG_CLASS_CHANNELS channels while populating P2P channels. The
current limits on the operating classes or channels per operating class
could be hit in some case (mainly, with 6 GHz, but in theory, with a
2.4/5/60 GHz capable device as well).

If the local driver advertised a larger number of supported operarting
classes or channels per operating class, the construction of the struct
p2p_reg_class instances could have resulted in writing beyond the end of
the buffer and ending up corrupting memory around the struct p2p_config.
This could result in unexpected behavior in some other operations that
used corrupted memory, e.g., generation of a P2P Channel List failing
(with validation code stopping the process to avoid writing beyond the
end of the message buffer) due to not having sufficient buffer space for
the corrupted data.

This issue is triggered only based on information from the local driver
(mainly based on addition of support for 6 GHz band operating classes),
so the issue cannot be triggered based on received frames or any other
remote information.

The issue was introduced by commit d7c2c5c98c ("AP: Add initial
support for 6 GHz band") which added the operating class 131 which has
sufficiently large number of channels to go beyond the
P2P_MAX_REG_CLASS_CHANNELS limit.

c304bddcf9 DPP: Stop Action frame sequence on DPP_STOP_LISTEN and PKEX failure
Previously it was possible for the PKEX/DPP exchange to terminate with
an error and the ongoing Action frame TX/RX offchannel operation not
getting terminated. This could leave the driver waiting on offchannel
until timeout and failing following operations before that timeout
happens. Fix this by explicitly stopping the Action frame sequence in
the driver in the previously missed cases.

This fixes a case that was showing up with the following test sequence
every now and then:
dpp_qr_code_chan_list_unicast dpp_pkex_test_fail dpp_enrollee_reject_config

dpp_pkex_test_fail was adding a large number of pending offchannel
operations and dpp_enrollee_reject_config could fail if those pending
operations were blocking new remain-on-channel or offchannel TX
operation for a sufficiently long time.

adf3de44ca Add check to consider band in enabling connection_vht flag
connection_vht flag was set to true when both Association Request and
Response frame IEs have VHT capability. Thus all devices that have
support for the vendor specific partial VHT support in the 2.4 GHz band
were also being reported as VHT capable. However, IEEE Std 802.11ac-2013
defines VHT STA to operate in frequency bands below 6 GHz excluding the
2.4 GHz band.

Do not set connection_vht when the operating band is 2.4 GHz. This
avoids reporting wifi_generation 5 on the 2.4 GHz band and reserves the
generation value 5 for full VHT as defined in the IEEE 802.11 standard.

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.

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.

144314eaa7 wpa_supplicant: Send EAPOL frames over nl80211 where available
Linux kernel v4.17 added the ability to request sending control port
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 a TX_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.

Update the RSN supplicant system to use this new operation for sending
EAPOL-Key frames when the driver reports that this capability is
available; otherwise, fall back to a normal Ethernet TX.

I have tested this on DMG (11ad/ay) devices with an out-of-tree Linux
driver that does not use mac80211. Without this patch I consistently see
PTK rekeying fail if message 4/4 shares a stream with other in-flight
traffic. With this patch, and the driver updated to flush the relevant TX
queue before overwriting a PTK (knowing, now, that if there was a message
4/4 related to the key installation, it has already entered the driver
queue), rekeying is reliable.

There is still data loss surrounding key installation - this problem is
alluded to in IEEE Std 802.11-2016, 12.6.21, where extended Key ID
support is described as the eventual solution. This patch aims to at
least prevent rekeying from totally breaking the association, in a way
that works on kernels as far back as 4.17 (as per Alexander Wetzel
extended Key ID support should be possible on 5.2).

See http://lists.infradead.org/pipermail/hostap/2019-May/040089.html for
a little more context.

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.

a2c1bebd43 Improve roaming logic
Currently, wpa_supplicant may roam too aggressively; the need_to_roam()
function will return early with a roaming decision if the difference in
signal level or throughput between the current and selected APs is
"sufficiently large." In particular, if the selected AP's estimated
throughput is more than 5k greater than the current AP's estimated
throughput, wpa_supplicant will decide to roam. Otherwise, if the
selected AP's signal level is less than the current AP's signal level,
or the selected AP's estimated throughput is at least 5k less than the
current AP's estimated throughput, wpa_supplicant will skip the roam.
These decisions are based only on one factor and can lead to poor
roaming choices (e.g., a roam should not happen if the selected AP's
estimated throughput meets the threshold but the current signal and
throughput are already good, whereas a roam should happen if the signal
is slightly worse but the estimated throughput is significantly better).

This change standardizes the roaming heuristic for signal strength
difference requirements and will hopefully improve user experience. The
change can be summarized as follows: based on the current signal level,
a certain roaming difficulty is assigned. Based on the selected AP's
estimated throughput relative to the current AP's estimated throughput,
the difficulty is adjusted up or down. If the difference in signal level
meets the threshold, a roam happens.

The hard-coded values were selected purely based on the previous version
of this function. They may eventually need to be fine-tuned for optimal
performance.

from scan results and the current BSS for such cases.

f4f7600adf Use signal_poll noise information for roaming, if available
Using average signal strength from the driver and hardcoded noise floor
does not look like an ideal design since there can be significant
differences in the driver-reported noise floor values. Furthermore, even
though the current noise floor is a snapshot from the driver, it is
common for drivers to use a noise floor value from a longer calibration
step and that should not prevent the driver provided value from being
used. This makes the comparisons of the signal strengths between the
current AP (signal_poll) and other APs (scan) more accurate.

As an example, test runs in home environment showed 5 dB difference
between the driver reported noise floor and the hardcoded value and this
could result in significant differences in estimated throughput
calculation.

69ccc557d8 wpa_supplicant: Fall back to avg_signal in roaming decision
Some drivers (e.g. Marvell WiFi) don't report avg_beacon_signal, but
it's still useful to poll for the signal again when a roaming decision
needs to be made. Use si.avg_signal when si.avg_beacon_signal is not
available.

7e7b23e229 Update throughput estimate for the current BSS based on signal poll
We saw that on certain platforms in certain places we keep switching
between two APs and eventually get the same RSSI. Debugging showed that
we have a very big difference between the two antennas.

Ant A can hear AP A very well (-60) but AP B very bad (-80)
Ant B can hear AP B very well (-60) but AP A very bad (-80)

When the device associates to AP A, it'll learn to use Ant A. If the
device uses one single antenna to receive the scan results, it may hear
the AP it is currently associated to on the second antenna and get bad
results. Because of that, the wpa_supplicant will roam to the other AP
and the same scenario will repeat itself:

Association to AP A (Ant A reports -60).
Scan on Ant A: AP A: -60, AP B: -80
Scan on Ant B: AP A: -80, AP A: -60 ==> ROAM.

Association to AP B (Ant B reports -60)
Scan on Ant A: AP A: -60, AP B: -80 ==> ROAM

Etc...

Improve this by querying the signal level of the current AP using
drv_signal_poll() instead of relying on the signal level that we get
from the scan results. Also update the throughput estimate based on the
likely more accurate values for the current association.

078217a2d7 STA OBSS: Update secondary channel info after CSA
Field wpa_s->sme.ht_sec_chan keeps secondary channel for the 40 MHz
band. This field is used to prepare a list of channels for the STA OBSS
scan. Initially, the secondary channel is set to HT_SEC_CHAN_UNKNOWN.
Later on, in function wpa_obss_scan_freq_list() it is obtained from the
current BSS HT operation IE. However, the secondary channel information
is not updated after channel switch, which may lead to an incorrect list
of channels prepared for the STA OBSS scan.

Update ht_sec_chan according to the channel switch event data to fix
this.

3204795d7a STA OBSS: Add check for overlapping BSSs
In the previous implementation connected STA performs OBSS scan
according to requests from its 20/40 MHz AP. However STA checks only 40
MHz intolerance subfield from HT Capabilities element in scan results.
Meanwhile, as per IEEE Std 802.11-2016, 11.16.12, STA should check
overlapping BSSs as well.

Note that all the required code to check overlapping BSSs did already
exist for AP mode since AP does those checks properly before operating
as 20/40 MHz BSS in the 2.4 GHz band. Use that existing code by replace
existing 40 MHz intolerance check in sme_proc_obss_scan() with the new
shared helper function check_bss_coex_40mhz().
