This function takes an Operating Channel and a Country String to convert
it into a band. Using scan_oper_class_to_band and scan_channel_to_freq,
an Operating Channel, a Country String and a Channel Number together can
be converted into an actual frequency. EU and US country codes based on
wpa_supplicant's tables.
It doesn't matter for crypto_derive_pairwise_ptk in non-SHA256 mode
but in the FT PTK derivation function, as well as in SHA256 mode all
bytes of the output do actually change with the PTK size.
Fix autoconnect trying to connect to networks never used before as found
by Tim Kourt. Update the comments to be consistent with the use of the
is_known field and the docs, in that a Known Network is any network that
has a config file in the iwd storage, and an autoconnect candidate is a
network that has been connected to before.
If the handshake fails, we trigger a deauthentication prior to reporting
NETDEV_RESULT_HANDSHAKE_FAILED. If a netdev_disconnect is invoked in
the meantime, then the caller will receive -ENOTCONN. This is
incorrect, since we are in fact logically connected until the connect_cb
is notified.
Tweak the behavior to keep the connected variable as true, but check
whether disconnect_cmd_id has been issued in the netdev_disconnect_event
callback.
If the device is currently connected, we will initiate a disconnection
(or wait for the disconnection to complete) prior to starting the
WSC-EAP association.
Use the org.freedesktop.DBus.Properties interfaces on objects with
properties and drop the old style GetProperty/SetProperty methods on
individual interfaces. Agent and KnownNetworks have no properties at
this time so don't add org.freedesktop.DBus.Properties interfaces.
We send the scan results where we obtained a PushButton target over to
device object. If EAP-WSC transaction is successful, then the scan
results are searched to find a network/bss combination found in the
credentials obtained. If found, the network is connected to
automatically.
This also fixes a potential buffer overflow since the ssid was cast to a
string inside network_create. However, ssid is a buffer of 32 bytes,
and would not be null-terminated in the case of a 32-byte SSID.
