Channel 100 is a valid channel to choose for 80 MHz operation. However,
it was converted to 5500 MHz, not 5550 MHz, for the 80 MHz case while
the conversion to other bandwidths was done correctly. In fact, there is
no channel assigned to this frequency 5550 MHz.
Fix this obvious typo to allow ACS to select channel 100 for 80 MHz
operation again.

Use monitor interface to send_mlme only when the interface is configured
in AP mode. In multiple interface setup, one interface can be configured
in AP mode using monitor interface and another interface in station
mode. The station interface may also require sending the management
frames without using monitor interface, e.g., support external SAE
authentication to send Authentication frames without monitor interface.
This change allows sending management frames to the driver for a station
interface where the AP interface uses monitor interface.
Additionally, the monitor interface is only valid for AP mode
(nl80211_create_monitor_interface() is called in nl80211_setup_ap) so
interface type check ensures to use monitor interface only when required
by the specific interface.

according to OpenSSL documentation [1], EVP_CIPHER_CTX_set_padding()
should be called after EVP_EncryptInit_ex(), EVP_DecryptInit_ex(), or
EVP_CipherInit_ex(). Not doing this causes EVP_CIPHER_CTX_set_padding()
to return false on OpenSSL-3.0.0, resulting in the impossibility to
connect in many scenarios. Fix this changing the order of function calls

NetworkManager-CI detected systematic failures on test scenarios using
MSCHAPv2 when wpa_supplicant uses OpenSSL-3.0.0.
The 'test_module_tests.py' script also fails, and the following log is
shown:

1627404013.761582: ms_funcs: 1 error
It seems that either DES_set_key() or DES_ecb_encrypt() changed their
semantic, but it doesn't make sense to fix them since their use has been
deprecated. Converting des_encrypt() to avoid use of deprecated
functions proved to fix the problem, and removed a couple of build

Commit 0b8889d8e5 ("P2P: Do not stop Listen state if it is on

remain-on-channel to send out GO Negotiation response frame quickly.
But in Listen state, if GO Negotiation request frame is received before
the remain-on-channel started event from the driver, the above
optimization is not triggered. This showed up in following manner in the
debug log:

nl80211: Remain-on-channel event (cancel=1 freq=2412 channel_type=0 duration=0 cookie=0x100 (match))
P2P: GO Negotiation Response (failure) TX callback: success=0
Fix this by adding p2p->pending_listen_freq == freq condition for the
optimization so that the case where the remain-on-channel command has
already been issued to the driver, but the start event has not yet been
received, is covered as well.

When the driver provides a list of supported modes, hostapd ended up
adding channel 6 even if the 2.4 GHz mode was not included. This
resulted in incorrect behavior of trying to transmit on a not supported
channel in case of 5 GHz only radios.
Fix this by adding the channel 6 by default only if the driver does not
provide a list of supported modes. Whenever the supported modes are
available, only add this channel if it is explicitly listed as an
enabled channel.
This is similar to an earlier wpa_supplicant change in commit
8e5739c3ac ("DPP2: Check channel 6 validity before adding it to chirp

wpa_supplicant having a PMKSA for FILS authentication without having

Some of the reconfiguration cases (e.g., with WPS reconfiguration
enabling WPA/WPA2) might end up calling hostapd_setup_wpa() twice
without calling hostapd_deinit_wpa() in the middle. This would have
resulted in a memory leak since the PTKSA cache was being reinitialized
without freeing previous memory allocation.
Fix this by making PTKSA cachine initialization independent of
hapd->wpa_auth so that reinitialization does not happen in a manner that
would have overridden the old hapd->ptksa pointer without freeing the
referenced resources.

Use WPA3-Personal (SAE+PMF) for P2P connections in the 6 GHz band to
enable the Wi-Fi Display use case on the 6 GHz band without having to
use WPA2-Personal (PSK) on that new band.

Previously, 6 GHz channels were disabled for P2P operations. Use the new
allow_6ghz parameter with P2P_CONNECT, P2P_GROUP_ADD, and P2P_INVITE
commands for P2P connection on the 6 GHz channels when Wi-Fi Display is
enabled on both the devices.
However, the p2p_6ghz_disable parameter in the configuration takes a
higher precedence.
Indicate P2P 6 GHz band capable information in Device Capability Bitmap
of P2P Capability attribute to indicate the P2P Device is capable of P2P
operation in the 6 GHz band.

Previously, the 6 GHz channels were disabled for P2P operations.
Introduce a new include_6ghz parameter for the P2P_FIND command to
configure P2P discovery on the 6 GHz channels.
However, the p2p_6ghz_disable parameter in the configuration takes a
higher priority. If the p2p_6ghz_disable parameter is not set in the
configuration, include_6ghz parameter can be used to enable or disable
the discovery operation in the 6 GHz channels for the P2P_FIND command.

hostapd_handle_dfs_offload() is the DFS handler for the offloaded case,
in which ieee80211_is_dfs() is used to check if the configured frequency
requires DFS or not.
When the configured channel width is not 20 (e.g., 160),
ieee80211_is_dfs() will not checked adjacent freqs, so it possibly makes
wrong conclusion for whether DFS is required.
hostapd_is_dfs_required() does similar thing with ieee80211_is_dfs()
except it supports checking whether the configured frequency and its
adjacent frequencies require DFS. So hostapd_is_dfs_required() is a more
robust and better option than ieee80211_is_dfs() to check DFS.
The issue is hostapd_is_dfs_required() is for non-offload case due to
the check of the configuration parameter ieee80211h. Add a check for
WPA_DRIVER_FLAGS_DFS_OFFLOAD to make it support the DFS offload case
(i.e., ieee80211h=0) as well.
For example, configuring the AP to start at freq=5240 with channel width
160:
- Existing hostapd checks freq=5240 is non-DFS, hence skip DFS CAC and
transition to AP-Enabled which volatiles DFS-RADAR detection.
LOG: "hostapd : hostapd_handle_dfs_offload: freq 5240 MHz does not
require DFS. Continue channel/AP setup"
- This commit checks freq=5240 and its adjacent freqs are DFS required,
hence remains in DFS state until DFS CAC completed.
LOG: "hostapd : hostapd_handle_dfs_offload: freq 5240 MHz requires
DFS for 4 chans"

When regulatory rules are configured not to support 40 MHz channels on
the 2.4 GHz band, hostapd_is_usable_chans() still allowed 40 MHz
channels (i.e., 1-9) to be used with ht_capab=[HT40+][HT40-].
Looking into hostapd_is_usable_chans():
1) Validate primary channel using hostapd_is_usable_chan()
2) Try to pick a default secondary channel if hostapd_is_usable_chan()
3) Try to pick a valid secondary channel if both HT40+/HT40- set, and
further validate primary channel's allowed bandwidth mask.
4) Return channel not usable.
For example, for the 2.4 GHz channel 9 in Japan, its default secondary
channel is 13, which is valid per hostapd_is_usable_chan(), so step (2)
returns channel usable.
Add a more strict check to step (2) to clearly reject 40 MHz channel
configuration if regulatory rules do not allow the 40 MHz bandwidth,
which is similarly done in commit ce6d9ce15b ("hostapd: Add supported
channel bandwidth checking infrastructure").
