Android platform assigns the same socket id if the socket identifier in
conf->ctrl_interface and global->params.ctrl_interface (parameter for
android_get_control_socket) point to the same Android specific control
socket. This ends up having two eloop socket handlers registered for the
same file descriptor and thus, two attempt to receive and process each
command. This can result in unexpected failure, e.g., the prefix IFNAME=
for any command is valid for global socket handler, but results in
UNKNOWN COMMAND response from the per-interface ctrl socket handler).
Since it might be possible to end up with this type of invalid
configuration in OTA upgrade, compare the socket identifiers and do not
open the ctrl socket on the respective interface if both point to same.
This allows the Wi-Fi framework to use the global control interface.

This was already the case for most command sequences, but it was
possible for wpa_s->reassociate to be set to 1 when CTRL-RSP-* commands
were used to set identity, password, or passphrase for EAP

It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.
Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
BSS.

Upon any change in the currently used channels evaluate if a GO should
move to a different operating frequency, where the possible scenarios:
1. The frequency that the GO is currently using is no longer valid,
due to regulatory reasons, and thus the GO must be moved to some
other frequency.
2. Due to Multi Concurrent Channel (MCC) policy considerations, it would
be preferable, based on configuration settings, to prefer Same
Channel Mode (SCM) over concurrent operation in multiple channels.
The supported policies:
- prefer SCM: prefer moving the GO to a frequency used by some other
interface.
- prefer SCM if Peer supports: prefer moving the GO to a frequency
used by some other station interface iff the other station
interface is using a frequency that is common between the local and
the peer device (based on the GO Negotiation/Invitation signaling).
- Stay on the current frequency.
Currently, the GO transition to another frequency is handled by a
complete tear down and re-setup of the GO. Still need to add CSA flow to

The mesh SAE auth often fails with master branch. By bisect I found
commit eb5fee0bf5 ('SAE: Add side-channel
protection to PWE derivation with ECC') causes this issue. This does not
mean the commit has a bug. This is just a CPU resource issue.
After the commit, sae_derive_pwe_ecc() spends 101(msec) on my PC (Intel
Atom N270 1.6GHz). But dot11RSNASAERetransPeriod is 40(msec). So
auth_sae_retransmit_timer() is always called and it can causes
continuous frame exchanges. Before the commit, it was 23(msec).
On the IEEE 802.11 spec, the default value of dot11RSNASAERetransPeriod
is defined as 40(msec). But it looks short because generally mesh
functionality will be used on low spec devices. Indeed Raspberry Pi B+
(ARM ARM1176JZF-S 700MHz) requires 287(msec) for new
sae_derive_pwe_ecc().
So this patch makes the default to 1000(msec) and makes it configurable.
This issue does not occur on infrastructure SAE because the

If a device may be an explicit GO, it adds the GO details in the PD
Request. First, we try to reuse an active GO. If it is not present, we
try to reuse a non-active persistent group. In the latter case, if a
dedicated P2P interface is needed, the intended address should be that
of the pending interface. However, the wpas_get_go_info() provided the
ssid->bssid address, which is the address of the P2P device. This might
result in an incorrect intended interface attribute in the PD Request in
case a separate group interface is used.
Fix this by setting group_iface variable to true only if a dedicated

Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.
Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.

Previously, wpa_supplicant was using number of scan iterations
(WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP
with Selected Registrar TRUE before starting to iterate through all WPS
APs. While this works fine in most cases, some drivers may return the
initial three scan results so quickly that the total amount of time is
only couple of seconds in case none of the APs are initially advertising
Selected Registrar TRUE. To give some more time for APs (WPS Registrars)
to become ready, add an additional constraint on the iteration based on
time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).

Previously, within-ESS roaming was skipped if the selected BSS did not

higher rates (HT/VHT MCS).

restricted based on SNR.
In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not

When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when

new one given by the signal change event. This leads sometimes to bad

need to reply to PD Request to allow this code path to be triggered.
When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.

When noise floor measurements are not available, compute SNR
using default values for the noise floor. This helps steer us
towards 5 GHz BSSes in high signal strength environments.
In more detail...
Existing code prefers a 5 GHz BSS when the 5 GHz BSS's signal
strength is "close" to that of the 2.4 GHz BSS, or when both SNRs
are large. However, the mwifiex driver does not provide noise
floor measurements, so we can't compute SNRs.
Because mwifiex doesn't provide NF measurements, the "large SNR"
code wasn't effective. By using default values for the noise floor,
we can again compute SNRs, and decide that the SNR is high enough
that we shouldn't worry about the exact difference in SNR.
The default noise floor values (one for 2.4 GHz, and one for 5 GHz)
were chosen by measurement in a noisy environment, so they should be
conservative.
Note that while this patch is motivated by mwifiex, it affects
ath9k as well. Although ath9k provides noise floor measurements
in general, it will sometimes fail to provide a measurement for
one or more specific channels.
As a result of this patch, we'll always compare BSSes based on SNR
(either measured or estimated), rather than sometimes comparing
based on signal strength. ("Always" assumes that the
WPA_SCAN_LEVEL_DBM flag is set. It is for mwifiex and ath9k.)
While there:
- fix a whitespace issue (spaces -> tab)
- clean up existing comments
- update dump_scan_res to indicate whether the noise floor is
measured, or default

For wired IEEE 802.1X authentication, phase1="allow_canned_success=1"
can now be used to configure a mode that allows EAP-Success (and
EAP-Failure) without going through authentication step. Some switches
use such sequence when forcing the port to be authorized/unauthorized or
as a fallback option if the authentication server is unreachable. By
default, wpa_supplicant discards such frames to protect against
potential attacks by rogue devices, but this option can be used to
disable that protection for cases where the server/authenticator does
not need to be authenticated.
When enabled, this mode allows EAP-Success/EAP-Failure as an immediate
response to EAPOL-Start (or even without EAPOL-Start) and EAP-Success is
also allowed immediately after EAP-Identity exchange (fallback case for
authenticator not being able to connect to authentication server).

wpa_supplicant used to request user to re-enter username/password if the
server indicated that EAP-MSCHAPv2 (e.g., in PEAP Phase 2)
authentication failed (E=691), but retry is allowed (R=1). This is a
reasonable default behavior, but there may be cases where it is more
convenient to close the authentication session immediately rather than
wait for user to do something.
Add a new "mschapv2_retry=0" option to the phase2 field to allow the
retry behavior to be disabled. This will make wpa_supplicant abort
authentication attempt on E=691 regardless of whether the server allows
retry.

Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge:
respect RFC2863 operational state') from 2012 introduced a regression
for using wpa_supplicant with EAPOL frames and a station interface in a
bridge. Since it does not look like this regression is going to get
fixed any time soon (it is already two years from that commit and over
1.5 from a discussion pointing out the regression), add a workaround in
wpa_supplicant to avoid this issue.
The wpa_supplicant workaround uses a secondary packet socket to capture
all frames (ETH_P_ALL) from the netdev that is in a bridge. This is
needed to avoid the kernel regression. However, this comes at the price
of more CPU load. Some of this is avoided with use of Linux socket
filter, but still, this is less efficient than a packet socket bound to
the specific EAPOL ethertype. The workaround gets disabled
automatically, if the main packet socket interface on the bridge
interface turns out to be working for RX (e.g., due to an old kernel
version being used or a new kernel version having a fix for the
regression). In addition, this workaround is only taken into use for the
special case of running wpa_supplicant with an interface in a bridge.

Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.
In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.
Signed-off-by: Bob Copeland <me@bobcopeland.com>
Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).
The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

For Interworking connection to work, the SSID of the selected BSS needs
to be known to be able to associate with the AP. It was possible for the
scan results to include two BSS entries matching the BSSID when an
earlier scan with that AP has shown a hidden SSID configuration (e.g.,
when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get
rejected for Interworking connection.
Fix this by confirming that the selected BSS entry has a real SSID. If
not, try to find another BSS entry matching the same BSSID and use that,
if found with an SSID.
