There is a difference between an unset JSON array element and an empty
one. Don't loose that information.
|
| |
|
|
|
| |
We will need to emit property changed signals. For that we need to know
whether the property changes. Compare it.

- use nm_auto_decref_json for "json_value" to indicate ownership
transfer.
- don't reuse variable json_element and json_link to construct
watchers list. It's confusing. In general, use different variables
for different purposes.
|
| | |
|
| | |
|
| |
|
|
|
|
| |
_nm_utils_team_config_get() determines the type based on the JSON content.
Hence, the caller must validate that the returned GValue is of the expected
type, or it will trigger an assertion/crash.
|
| |
|
|
|
|
| |
Use nm_auto*, it's almost always harder to get wrong, because
ownership (and lifetime management of a variable, and what it points
to) is more clearly expressed.

Open vSwitch is the special kid on the block -- it likes to be in charge of
the link lifetime and so we shouldn't be. This means that we shouldn't be
attempting to remove the link: we'd just (gracefully) fail anyways.
More importantly, this also means that we shouldn't care if we see the link
go away. We may already be activating another connection and shouldn't alter
the device state when OpenVSwitch decides to drop the old link.

This will be soon useful as we are going to drop the reference to the
Device objs: so, when a checkpoint is created and a device disappear
(hw removed or sw device deleted) we will be able to correctly perform
the rollback.

The "activate" label is used only for unrealized software devices that
should be recreated. Move the label to skip useless checks.

that is: when a Device gets unexported from DBus. In this way we will
allow "Devices" property to be rechecked on get() returning an
up-to-date "Devices" property value.

This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.
Removing the libraries allows us to:
* Remove the horrible hacks that were in place to deal with accidental use
of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
strings.
* Get rid of known bad code without chances of ever getting fixed
(libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace
If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

This is wrong -- we may want to start activating before device is
registered if it the SIM needs unlocking with a PIN code that's included
in the connection.

After 1.16.0 is released, merge it back into master so that
1.16.0 is part of the history of master. That means,
$ git log --first-parent master
will also traverse 1.16.0 and 1.16-rc*.
Also bump the micro version to 1.17.1-dev to indicate that this is
after 1.16.0 is out.

The routing-rule tests generate a number of routing rules and tries to
add and delete them.
For that, _rule_create_random() sets random fields of the rule.
Note that especially interesting are rules that leave most fields
unset (at zero), because they trigger kernel issues rh#1686075 and
rh#1685816.
But a rule has many fields, so in order to generate rules that have most
fields unset, we need to use low probabilities when rolling the dice for
setting a field. Otherwise, most rules end up with several fields set
and don't reproduce the kernel issue (especially the test failed to hit
rh#1686075).

Routing rules are unlike addresses or routes not tied to an interface.
NetworkManager thinks in terms of connection profiles. That works well
for addresses and routes, as one profile configures addresses and routes
for one device. For example, when activating a profile on a device, the
configuration does not interfere with the addresses/routes of other
devices. That is not the case for routing rules, which are global, netns-wide
entities.
When one connection profile specifies rules, then this per-device configuration
must be merged with the global configuration. And when a device disconnects later,
the rules must be removed.
Add a new NMPRulesManager API to track/untrack routing rules. Devices can
register/add there the routing rules they require. And the sync method will
apply the configuration. This is be implemented on top of NMPlatform's
caching API.

Add and implement NMPlatformRoutingRule types and let the platform cache
handle rules.
Rules are special in two ways:
- they don't have an ifindex. That makes them different from all other
currently existing NMPlatform* types, which have an "ifindex" field and
"implement" NMPlatformObjWithIfindex.
- they have an address family, but contrary to addresses and routes, there
is only one NMPlatformRoutingRule object to handle both address
families.
Both of these points require some special considerations.
Kernel treats routing-rules quite similar to routes. That is, kernel
allows to add different rules/routes, as long as they differ in certain
fields. These "fields" make up the identity of the rules/routes. But
in practice, it's not defined which fields contribute to the identity
of these objects. That makes using the netlink API very hard. For
example, when kernel gains support for a new attribute which
NetworkManager does not know yet, then users can add two rules/routes
that look the same to NetworkManager. That can easily result in cache
inconsistencies.
Another problem is, that older kernel versions may not yet support all
fields, which NetworkManager (and newer kernels) considers for identity.
The older kernel will not simply reject netlink messages with these unknown
keys, instead it will proceed adding the route/rule without it. That means,
the added route/rule will have a different identity than what NetworkManager
intended to add.

Currently, there is a directy one to one relation between
- DELAYED_ACTION_TYPE_REFRESH_ALL_*
- REFRESH_ALL_TYPE_*
- NMP_OBJECT_TYPE_*
For IP addresses, routes and routing policy rules, when we request
a refresh-all (NLM_F_DUMP), we want to specify the address family.
For addresses and routes that is currently solved by having two
sets of NMPObject types, for each address family one.
I think that is cumbersome because the implementations of both address
families are quite similar. By implementing both families as different
object types, we have a lot of duplicate code and it's hard to see where
the families actually differ. It would be better to have only one NMPObject
type, but then when we "refresh-all" such types, we still want to be able
to dump all (AF_UNSPEC) or only a particular address family (AF_INET, AF_INET6).
Decouple REFRESH_ALL_TYPE_* from NMP_OBJECT_TYPE_* to make that
possible.

| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
REFRESH_ALL_TYPE_*
While these numbers are strongly related to DELAYED_ACTION_TYPE_REFRESH_ALL_*,
they differ in their meaning.
These are the refresh-all-types that we support. While some of the delayed-actions
are indeed for refresh-all, they are not the same thing.
Rename the enum.

The function is unused. It would require redesign to work with
future changes, and since it's unused, just drop it.
The long reasoning is:
Currently, a refresh-all is tied to an NMPObjectType. However, with
NMPObjectRoutingRule (for policy-routing-rules) that will no longer
be the case.
That is because NMPObjectRoutingRule will be one object type for
AF_INET and AF_INET6. Contrary to IPv4 addresses and routes, where
there are two sets of NMPObject types.
The reason is, that it's preferable to treat IPv4 and IPv6 objects
similarly, that is: as the same type with an address family property.
That also follows netlink, which uses RTM_GET* messages for both
address families, and the address family is expressed inside the
message.
But then an API like nm_platform_refresh_all() makes little sense,
it would require at least an addr_family argument. But since the
API is unused, just drop it.
|
| | | |
| | |
| | |
| | |
| | | |
When we refresh all links, we clear all flags to refresh a specific
link. However, only log a message if there was anything to clear.
|
| | | |
| | |
| | |
| | |
| | |
| | | |
This allows the compiler to see that this function does nothing for %NULL.
That is not so unusual, as we use nm_auto_nmpobj to free objects. Often
the compiler can see that these pointers are %NULL.

NMPObject types
Until now, all implemented NMPObject types have an ifindex field (from
links, addresses, routes, qdisc to tfilter).
The NMPObject structure contains a union of all available types, that
makes it easier to down-case from an NMPObject pointer to the actual
content.
The "object" field of NMPObject of type NMPlatformObject is the lowest
common denominator.
We will add NMPlatformRoutingRules (for policy routing rules). That type
won't have an ifindex field.
Hence, drop the "ifindex" field from NMPlatformObject type. But also add
a new type NMPlatformObjWithIfindex, that can represent all types that
have an ifindex.
|
| | | | |
|
| | | |
| | |
| | |
| | |
| | | |
It's wrong to cast here. The caller must always provide an
NMPObject pointer.
