Yu Watanabe 32f8a613c5 sd-dhcp-lease: store static routes and classless static routes in different arrays 
When classless static routes option is provided, then static routes
option should not be used. Hence, let's not mix and store them in one
storage.

This introduce sd_dhcp_lease_get_static_routes() and
sd_dhcp_lease_get_classless_routes().

Yu Watanabe fd11005951 network: xfrm: refuse zero interface ID 
Since kernel 5.17-rc1, 5.16.3, and 5.15.17 (more specifically,
https://github.com/torvalds/linux/commit/8dce43919566f06e865f7e8949f5c10d8c2493f5)
the kernel refuses to create an xfrm interface with zero ID.

Yu Watanabe 3cf58ef316 network: do not free bound_by carrier map on reconfigure 
Otherwise, if a link enters unmanaged state, then its carrier state does
not propagated to other interfaces.

Even such spurious situation, do not drop the localhost addresses.

Yu Watanabe a0e99a377a network: remove only managed configs on reconfigure or carrier lost 
Otherwise, if the carrir of the non-managed interface is lost, the
configs such as addresses or routes on the interface will be removed by
networkd.

Yu Watanabe cd7fcda543 wait-online: make manager_link_is_online() return 0 when in unmanaged state 
Previously, even if a link is in unmanaged state, the function may
returns positive value. So, even if all managed links are in the configured
sate but do not satisfy the online criteria, e.g., IPv4 address state,
then wait-online finishes with positive value.

This makes the function always return 0 for unmanaged state. So, at
least one managed link must satisfies the online criteria.

This also adds more comments and debugging logs.

Fixes #22246.

Zbigniew Jędrzejewski-Szmek 100433e05a networkctl: use xsprintf a bit more 2022-01-14 16:24:27 +09:00
Zbigniew Jędrzejewski-Szmek d821e40ca9 networkctl: open the bus just once 
We'd connect to the bus twice: the first time to check networkd namespace,
and then the second time to do the deed we were asked to do. It's nicer
to open the bus just once, for efficience and also to avoid the open call
in all functions.

An ASSERT_PTR helper is added:
- sd_bus *bus = userdata;
  ...
- assert(bus);
+ sd_bus *bus = ASSERT_PTR(userdata);
  ...

It can be used in other place too, but I'm leaving that for a later
refactoring.

Yu Watanabe 902bbdc4b6 network: use scope link for direct unicast routes by default 
Strictly speaking, this breaks the backward compatibility, but I guess
in most cases people already sets Scope=link for such routes.

This behavior matches with how 'ip route' command adds such route by
default.

Jan Janssen bbec46c817 meson: Use files() for fuzzers 
Not having to provide the full path in the source tree is much
nicer and the produced lists can also be used anywhere in the source
tree.
