Based on the now documented seg0/seg1 values from offloaded ACS, there
is a mismatch between the driver interface and internal hostapd use.
The value of segment0 field in ACS results is the index of the channel
center frequency for 20 MHz, 40 MHz, and 80M Hz channels. The value is
the center frequency index of the primary 80 MHz segment for 160 MHz and
80+80 MHz channels.
The value of segment1 field in ACS results is zero for 20 MHz, 40 MHz,
and 80 MHz channels. The value is the index of the channel center
frequency for 160 MHz channels and the center frequency index of the
secondary 80 MHz segment for 80+80 MHz channels.
However, in struct hostapd_config, for 160 MHz channels, the value of
the segment0 field is the index of the channel center frequency of 160
MHz channel and the value of the segment1 field is zero. Map the values
from ACS event into hostapd_config fields accordingly.

Update the documentation with values to be sent for seg0 and seg1 fields

of seg0 and seg1 fields in the IEEE 802.11 standard.
This vendor command had not previously been documented in this level of
detail and had not actually been used for the only case that could have
two different interpretation (160 MHz) based on which version of IEEE

The Channel Width field value is 0 for 20 MHz, 1 for 40 MHz, 2 for 80
MHz, and 3 for both 160 MHz and 80+80 MHz channels. The 80+80 MHz case
was not addressed previously correctly since it cannot be derived from
seg0 only.
The Channel Center Frequency Segment 0 field value is the index of
channel center frequency for 20 MHz, 40 MHz, and 80 MHz channels. The
value is the center frequency index of the primary 80 MHz segment for
160 MHz and 80+80 MHz channels.
The Channel Center Frequency Segment 1 field value is zero for 20 MHz,
40 MHz, and 80 MHz channels. The value is the index of the channel
center frequency for 160 MHz channel and the center frequency index of
the secondary 80 MHz segment for 80+80 MHz channels.

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.

tiny bit closer to each other over the air to increase testing coverage.

If a channel list changed event is received after a scan and before
selecting a BSS for connection, a BSS found on a now disabled channel
may get selected for connection. The connect request issued with the BSS
found on a disabled channel is rejected by cfg80211. Filter out the BSSs
found on disabled channels and select from the other BSSs found on
enabled channels to avoid unnecessary connection attempts that are bound
to fail.
The channel list information will be updated by the driver in cases like
country code update, disabling/enabling specific bands, etc. which can
occur between the scan and connection attempt.

In order to correctly encrypt rekeying frames, wpa_supplicant now checks

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).

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.

The p2p_long_listen value was set on the control wpa_s struct while in a
lot of cases it operated on the p2p struct. Explicitly use the global
p2p_init_wpa_s struct in cases where we might not be operating on it
already.
Without this, simply starting a p2p_listen operation (e.g., using
wpa_cli) will not work properly. As the p2p_long_listen is set on the
controlling interface and wpas_p2p_cancel_remain_on_channel_cb() uses
p2p_init_wpa_s, it would not actually work. This results in
wpa_supplicant stopping listening after the maximum remain-on-channel
time passes when using a separate P2P Device interface.
