a2c23195ad D-Bus: Use size_t for values theoretically larger than 16-bit int
These are theoretical cases with 32-bit integers, but cases that could

d2d16e3100 Use size_t instead of int or unsigned int for configuration items
While int and unsigned int are not going overflow in practice as 32-bit
values, these could at least in theory hit an integer overflow with
16-bit int. Use size_t to avoid such potential issue cases.

This avoids a theoretical unsigned integer overflow case with 32-bit

(though, even that part looks pretty theoretical in this particular case
of number of BSSs in scan results).

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.

3c73811507 OWE: Mark BSS for transition mode based on active OWE network profiles
It is possible for the hidden OWE BSS to be found based on SSID-specific
scan (e.g., from the special OWE scan mechanism). In that sequence, the
previously used learning of OWE BSS was skipped since the SSID was
already present in the BSS entry. This could result in not being able to
find a matching BSS entry for the OWE BSS in transition mode.

Fix this by adding the BSS flag for transition mode based on SSID
matching against currently enabled OWE network profiles in addition to
the previous mechanism.

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).

Replace the IFACE= prefix in UDP case with IFNAME= to be consistent with

when remote/udp used. This also fixes test_connectivity().

466e48dcd7 HT: Remove SMPS in AP mode
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:
04ee647d58 ("HT: Let the driver advertise its supported SMPS modes for AP mode")

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.

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.

641d79f165 SAE: Special test mode sae_pwe=3 for looping with password identifier
The new sae_pwe=3 mode can be used to test non-compliant behavior with
SAE Password Identifiers. This can be used to force use of
hunting-and-pecking loop for PWE derivation when Password Identifier is
used. This is not allowed by the standard and as such, this
functionality is aimed at compliance testing.

from the AP. Explicitly check that the value the AP uses matches what
the STA started with to avoid unexpected cases.
