This parameter has been available for more than just testing purposes,
i.e., OBSS scanning has already been used to enable 20-to-40 MHz channel
changes on 2.4 GHz.

If OBSS scan interval is not set, the AP must not schedule a timeout to
restore 40 MHz operation immediately after having moved to a 20 MHz
channel based on an unsolicited co-ex report. Fix this by scheduling the
timeout only if obss_interval is non-zero.
Since we do not currently support AP doing OBSS scans after the initial
BSS setup, this means practically that 40-to-20 MHz transition is
allowed, but 20-to-40 MHz is not with obss_interval=0. The latter gets
enabled if obss_interval is set to a non-zero value so that associated
STAs can take care of OBSS scanning.

It was possible for a Action frame sequence completion to stop an

It was possible for the previously requested remain-on-channel for P2P

timeout even though there was not supposed to be a following listen
operation anymore. Skip the driver event if we are not waiting for a new

Add password and machine_managed flag to database in case of machine
managed subscription to fix EAP-TTLS connection failure to production
AP. In case of user managed subscription, the entered password is added
to DB from the PHP script. However in machine managed subscription,
machine generated password is added only in SOAP messages and PPS MO. So
connection to production will fail as the generated password is not
present in the database used by AAA server.

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.

It was possible for the GTK-found-in-memory case to be triggered due to
a retransmission of EAPOL-Key msg 3/4 especially when running test cases
under heavy load (i.e., timeout on hostapd due to not receiving the 4/4
response quickly enough). Make this false failure report less likely by
waiting a bit longer after the connection has been completed before

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.
