When a value of a TYPE_BOTH option is read back from kernel it
contains both string and numeric values ("balance-rr 0"), so we must
chop off the number before adding the option to the setting. Also
change the default values of options to the string form so that the
option matching logic works.
There is no excuse for clients to send connections to NetworkManager
that have invalid/unknown fields. Just reject them.
As Reapply() is new API in nm-1-1, there is no problem with backward
compatibility.
If it's traversing from unavailable to disconnected (e.g. realizing
of the device was delayed because it was awaiting the parent connection),
then we just want to progress the activation.
We'll need to share the best conneciton logic and it's the only caller
of nm_device_get_available_connections(). Let's just move it all to
NMDevice and provide the best connection from there instead.
No point ins storing "TRUE" as value in the @shared_ips hash
table. That forces glib to allocate a separate storage for the
value. Just use g_hash_table_add() instead.
The fields in the neighbor variant should have a defined order.
Instead of sorting the hash table entries while constructing the
variant in lldp_neighbor_to_variant(), refactor the management of
the TLV attributes.
As we only support known attributes, we can
store them in an array at a known index instead of putting them
in a hash table.
An alternative would be to have explict fields for every known
attribute. That would be even more efficient, but requires more
work when adding new attributes.
We register the callback early on, so we get notified about
every single neighbor as they show up. No need to iterate over
them explicitly -- and probably, at that early state, there are
no neighbors yet.
The systemd event tells which neighbor changed. Make use
of this information and don't rebuild all the neighbors
all the time.
That means, we must also change our rate limiting. Instead of
rate limiting the processing of all neighbors, we process neighbors
right away but limit the notification that gobject property changed.
When we receive an update for a certain neighbor, the update
might be invalid and we want to reject it. However, we still
must create an invalid object to compare whether the update
causes a remove of a previously valid neighbor.
Let lldp_neighbor_new() create an instance as long as the
id fields are present.
Instead of replacing the whole hash with a new one (and all new by a new one,
LldpNeighbor instances), update the existing hash.
One point of this is that our process-all function requires less
comparisons and avoids duplicate work right earlier. E.g. if a neighbor
didn't change, we don't have to put it into a hash to compare later for
equality.
But more importantly, we preserve our LldpNeighbor instance instead
of recreating them all the time. Later, the LldpNeighbor will cache
the GVariant.
Otherwise the connection wouldn't verify:
<error> [1458066126.2270] device (eth10): Generated connection does not verify:
connection.type: property type should be set to '802-3-ethernet'
<debug> [1458066126.2271] manager: (eth10): can't assume; no connection
(cherry picked from commit 4b71939e9ac3df93bfe72af0eac42b4ebaf94e15)
The prune list is for elements that must be deleted from the list of
available connections. So, when processing all the existing
connections an element must be deleted from the prune list iff it's
available.

Make the test helper independent from the platform singleton instance.
That way, we can also use them for other platform instances (e.g. in a
different namespace).
Now we have:
"nm-sd.h" is a header file of NetworkManager with utilities
related to systemd. It can be used anywhere freely.
Also, systemd headers that are considered public API (like
"sd-event.h") can be used without restrictions.
When compiling the systemd sources, we always must include
"nm-sd-adapt.h" as first. Similarly, systemd headers must
not include "nm-sd-adapt.h", because they are either public
(in which case the adapter is not needed) or they are internal
(in which case they are themself included via a systemd source).
Sometimes, we must internal API (like "dhcp-lease-internal.h").
In this case, we also must include "nm-sd-adapt.h".
As the lldp API changed, adjust "nm-lldp-listener.c".
Note that the commit is not yet functional due to missing
sd_event_source_set_enabled() and sd_event_source_set_time().
Also assert against the number of properties in the attributes
and explicitly assert against the values of chassis-id-type,
port-id-type, and system-description.
str_if_set() was added to replace the non-standard gcc extension "?:".
However, "?:" is supported by clang as well and we already use it at
several places.
Also, str_if_set() did not follow our naming scheme and renaming to
nm_str_if_set() would be ugly. So just drop it.
When a VPN connection is active and the parent device becomes
unmanaged (due to device removal or system entering sleep), all
configurations are removed from the interface and the device is taken
down. After that, the VPN is disconnected and tries to remove the old
VPN configuration from device, causing the following assertion to
fail:
_replace_vpn_config_in_list: assertion '!old' failed
Remove the assertion as @old can be missing for valid reasons.
Coverity complains rightly about "strncpy (dst, ifname, IFNAMSIZ)"
because it might leave @dst non-NULL-terminated, in case @ifname
is too long (which already would be a bug in the first place).
Replace the strcpy() uses by a new helper nm_utils_ifname_cpy()
that asserts against valid arguments.
Since 87a3df2e57 ("device: remove default-unmanaged and refactor
unmanaged flags") the device must properly report the IS_SOFTWARE
capability in order to be potentially activated.
