IEEE Std 802.11-2020, 11.8.8 (Selecting and advertising a new channel)
doesn't restrict switching to a channel which is not in the same band as
the current band. But at the same time, there are some issues in
switching between the 2.4/5 GHz bands and the 6 GHz band. So limit the
check to consider the critical use case of switching from a 5 GHz channel
to a 2.4 GHz channel.

While setting up the P2P GO interface, wpa_supplicant sets the operating
channel width to CHANWIDTH_USE_HT in cases where it fails to set 80 MHz
bandwidth. In the same flow, update the operating class, too, according
to the channel width. This is to avoid setting up the operational
channel width back to 80 MHz from hostapd interface setup.

wpas_p2p_optimize_listen_channel() checks for the state and current ssid
of the interface calling this function. This check prevents the function
from setting the optimized listen channel. Since the listen channel is
stored in global P2P configuration data, do not check the state and
current interface of the caller.

If wpa_supplicant was build without CONFIG_IEEE80211R, the
exposed key-management capabilities should not include one of the
FT protocols. If someone would use a FT protocol in such situation,
it would fail anyway.

Previously, wpa_supplicant was using the current SSID for building the

The driver's SME may choose a BSS of a different ESS (SSID) compared to
the current SSID and trigger external authentication. If the chosen SSID
is not associated/selected before by wpa_supplicant it won't have the
H2E PT derived. Make sure to derive PT for SSID indicated in the
external authentication request.

Commit e3bd6e9dc0 ("P2P: Use another interface operating channel as
listen channel") allows P2P listen channel to be selected based on
another interface operating channel if it is one of social channels
(i.e., 2.4 GHz 1, 6, 11).
This optimization is disabled by default due to the technical
specification expectations, but since this can be quite helpful for
optimized behavior, enable it by adding p2p_optimize_listen_chan=1 to
the default Android configuration template.
After the secure association and PTK derivation are completed, if the
device supports LTF keyseed, generate the LTF keyseed using KDK and set
the ranging context to the driver by using the command

Set secure ranging context to the driver for a valid PTKSA entry in the

If 6 GHz is supported by the device but 6 GHz P2P is disabled, P2P
invitation would fail if the GO select an operating channel which is not
the preferred channel. The root cause is that the 5 GHz and 6 GHz bands
are both HOSTAPD_MODE_IEEE80211A so the 5 GHz channels would be added
twice for the P2P Client's following scanning frequency list. This will
cause scanning to fail with -EINVAL. Fix this by adding the 5 GHz
channels only once.
