We shall not only have a PropertyInfo. Most properties share common
behavior, that is, they have a type. Move the function pointers to
a NmcPropertyType structure, so that it can be reused for multiple
properties.
This promotes the idea that properties have a (limited) set of types
with some type specific behaviors. Contrary, to having each property
re-implement fully it's type. E.g. instead of having various property
re-define their full behavior as an "bool", have one property type
"bool" which can be attached to a property.
Add an improved way of tracking meta data about settings.
E.g. it is wrong to generate for each property a nmc_property_*_get_*()
function. Instead, there should be a meta data about the property
itself, and a mechanism to retrieve the property.
For now, only do this for NMSettingConnection and keep all the existing
infrastructure in place. Later on all settings shall be moved.
Especially to accomodate NmcOutputField mangles the concept of
setting-meta data, formatting options, and collecting output results.
It's a total hack, that will be need fixing later.
This will be solved differently by th/setting-user-data-bgo776276
branch. Revert the change for now, the same functionality will be
restored later.
This reverts commit 623d888801.
nm_utils_enum_to_str() may also output numeric values if there is no
corresponding "nick" for the enum/flag value.
For enums the value is in decimal and for flags the value is hexadecimal
(with a "0x" prefix).
The same was already supported by nm_utils_enum_from_str() when reading
the value. However, previously, reading a flag would only support hex
numbers and reading a enum would only support decimal numbers.
Extend that, to allow passing numbers in any base. For nm_utils_enum_to_str()
also make sure to never output nicks that may be misinterpreted as
numbers.
It is not uncommon that a flags type has also the value 0 mapped,
for example to "unknown" or "none".
In that case, we should not return an empty string, but instead
that zero value.
Also, flags actually have an unsigned type. That isn't a real
problem to cast it to a signed int. But be more careful about
it and use unsigned while handling unsigned values and only
cast to int once.
Commit 029a0a21ea ("device: split out cloned MAC decision from
nm_device_hw_addr_set_cloned()") accidentally removed the assignment
of the new device @hw_addr_type, which then was left to
HW_ADDR_TYPE_UNSET. As a consequence, we never restored the initial
MAC address when the connection was deactivated. Fix this.
Fixes: 029a0a21ea
Shift argc and argc manually between argument ant its value and use
next_arg() between arguments everywhere. Whill be useful to parse global
arguments.
This makes it possible to retain Internet connectivity when multiple devices
have a default route, but one with the link type of a higher priority can not
reach the Internet.
This moves tracking of connectivity to NMDevice and makes the NMManager
negotiate the best of known connectivity states of devices. The NMConnectivity
singleton handles its own configuration and scheduling of the permission
checks, but otherwise greatly simplifies it.
This will be useful to determine correct metrics for multiple default routes
depending on actual internet connectivity.
The per-device connection checks is not yet exposed on the D-Bus, since they
probably should be per-address-family as well.
These functions return static information, and don't require
a @setting argument. The list of options is interesting even
when having now setting instance at hand.
Document this to promise the user that passing %NULL is allowed.
It was allowed since when those functions were added.
