We keep the 'WHITELIST-ONLY' filter type name still as an option in
--filter-policy=[POLICY], but deprecated and with the better
'ALLOWLIST-ONLY' replacement suggested from now on.
These lists were used in the corresponding TTY_BLACKLIST and
TTY_MANUAL_SCAN_ONLY filter rules, in the LEGACY and PARANOID filter
types, which are no longer supported.
The DEFAULT_ALLOWED filter rule made sense only in the LEGACY filter
type, and therefore it is also now removed, leaving the
DEFAULT_FORBIDDEN fallback rule exclusively. In other words, there is
now no way to ask ModemManager to implicitly allow TTY ports; the only
way to do that is by explicit making the TTY ports fall in one filter
rule that would allow them.
This is not just a rename of the rule, we also now avoid doing an
explicit check on the port name as well, and we rely on subsystem
checks only; i.e. the same logic applied for net ports.
The port candidate rules already do a 'cdc-wdm*' device name check
so it shouldn't be a big deal.
This tag is completely redundant because users can whitelist the
platform TTY ports to use with the more generic ID_MM_DEVICE_PROCESS
tag, which is part of the explicit whitelist filter rule.
The udev tag that allows flagging devices that MAY be modems
(e.g. USB<->RS232 adapters) is only applicable to TTY devices, so
explicitly specify that in the tag name as well.
Until now the ID_MM_DEVICE_IGNORE udev tag was being used in the
internal blacklist of devices shipped by ModemManager when running in
either DEFAULT or PARANOID filter modes. The name of the tag is
extremely misleading because it doesn't really make the full device be
ignored, the tag only applied to TTY ports.
This commit repurposes the tag so that it applies to ANY kind of
port (e.g. TTY, NET, cdc-wdm...) and also to any kind of filter type
(i.e. also applicable in STRICT mode).
The internal blacklist shipped by ModemManager, which should NOT be
used in STRICT mode, uses a new tag name, ID_MM_TTY_BLACKLIST.
The new ID_MM_DEVICE_IGNORE tag is therefore much more usable and its
name is really meaningful. If there are users or third-party projects
adding their own udev rules with the ID_MM_DEVICE_IGNORE tag name,
they should have no problem as the new rule is more restrictive than
the old one.
Plugins may specify that specific vendor & product IDs or strings are not
supported. This is useful when plugins need to specify that they support
all devices of a given vendor except for some specific ones.
There's no real point in maintaining a separate `MMPlugin' interface, as all the
plugins will inherit from `MMPluginBase', so just merge them and simplify
everything.
