wiphy_select_akm will now check if BIP is supported, and if MFPR is
set in the scan_bss before returning either SAE AKMs. This will allow
fallback to another PSK AKM (e.g. hybrid APs) if any of the requirements
are not met.
Also add a mask parameter to wiphy_get_supported_iftypes to make sure
the SupportedModes property only contains the values that can be used
as Device.Mode.
dbus_iftype_to_string returns NULL for unknown iftypes, the strdup will
also return NULL and ret[i] will be assigned a NULL. As a result
the l_strjoinv will not print the known iftypes that might have come
after that and will the l_strfreev will leak the strduped strings.
This is a replacement for station's static select_akm_suite. This was
done because wiphy can make a much more intellegent decision about the
akm suite by checking the wiphy supported features e.g. SAE support.
This allows a connection to hybrid WPA2/WPA3 AP's if SAE is not
supported in the kernel.
DBus has certain rules on what constitutes a valid path. Since the
wiphy name is freeform, it is possible to set it such that the contents
do not contain a valid path.
We fall back to simply using the wiphy index as the path.
DBus strings must be valid utf8. The kernel only enforces that the
wiphy name is null terminated string. It does not validate or otherwise
check the contents in any way. Thus it is possible to have
non-printable or non-utf8 characters inside.
NL80211_CMD_SET_WIPHY can be used to set various attributes on the wiphy
object in the kernel. This includes ATTR_WIPHY_NAME among others. iwd
currently does not parse or store any of the other attributes, so we
react to changes in WIPHY_NAME only.
The wiphy attribute should never be repeated by the kernel, so this
check is ultimately not needed. This condition can also be easily
checked by looking at the iwmon output in case things do go terribly
wrong.
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.
Change the path for net.connman.iwd.Device objects to /phyX/Y and
register net.connman.iwd.Adapter at /phyX grouping devices of the same
wiphy.
Turns out no changes to the test/* scripts are needed.
