Initial OWE implementation used SHA256 when deriving the PTK for all OWE
groups. This was supposed to change to SHA384 for group 20 and SHA512
for group 21. The new owe_ptk_workaround=1 network parameter can be used
to enable older behavior mainly for testing purposes. There is no impact
to group 19 behavior, but if enabled, this will make group 20 and 21
cases use SHA256-based PTK derivation which will not work with the
updated OWE implementation on the AP side.

Initial OWE implementation used SHA256 when deriving the PTK for all OWE
groups. This was supposed to change to SHA384 for group 20 and SHA512
for group 21. The new owe_ptk_workaround parameter can be used to enable
workaround for interoperability with stations that use SHA256 with
groups 20 and 21. By default, only the appropriate hash function is
accepted. When workaround is enabled (owe_ptk_workaround=1), the
appropriate hash function is tried first and if that fails, SHA256-based
PTK derivation is attempted. This workaround can result in reduced
security for groups 20 and 21, but is required for interoperability with
older implementations. There is no impact to group 19 behavior.

Previous implementation was hardcoding use of SHA256 PMK-to-PTK
derivation for all groups. Replace that with hash algorithm selection
based on the length of the prime similarly to the way this was done for
other derivation steps in OWE.
This breaks backwards compatibility when using group 20 or 21; group 19
behavior remains same.

The 5 GHz channels are stored in one hw_features set with mode
HOSTAPD_MODE_IEEE80211A while the 6 GHz channels will need to be stored
in a separate hw_features set (but with same mode
HOSTAPD_MODE_IEEE80211A) due to possibility of different HT/VHT/HE
capabilities being available between the 5 GHz and 6 GHz bands.
Iterate through all hw_features sets and check and match the band of
channel supported by the hw_features set while getting the hw_features
set in get_mode(). This allows both the 5 GHz and 6 GHz channels to be
found and correct capabilities to be used in cases where the driver
reports different capability values between 5 and 6 GHz channels.

IEEE P802.11-REVmd was modified to require H2E to be used whenever
Password Identifier is used with SAE. Since wpa_supplicant and mac80211
do not yet support SAE H2E in mesh, Password Identifier cannot be used
in mesh cases. Remove the test cases that verified this behavior for now
to allow H2E to be required per updated REVmd definition. These test
cases will be restored once H2E is fully functionality in mesh cases.

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
in external ACS result event for 20 MHz, 40 MHz, 80 MHz, 160 MHz, and
80+80 MHz channels. These values match the changes done to definitions
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.

sae_confirm_immediate=2 can now be used in CONFIG_TESTING_OPTIONS=y

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.
