We checked if the link is up only when configuring (explicit) nexthop,
but we did not checked that when configuring route which has (implicit)
nexthop.
Let's move the checks from nexthop_is_ready_to_configure() to
gateway_is_ready(), which is called for both implicit and explict
nexthops.
Fixes#40106.
As all callers do not care if the address has peer address.
This also drops prefixlen argument as it is always zero.
Fixes a bug introduced by 42f8b6a808.
Fixes#31950.
Previously, a Route object is owned by a Link object corresponding to the
outgoing interface of the route, and a Route object that does not have
outgoing interface is owned by the Manager object.
However, there were several issues:
- if a route has a nexthop ID, then the corresponding nexthop may be
changed to use another interface, hence the outgoing interface of the
route may be changed.
- if a route requested with MultiPathRoute=, then the link who requests
the route is different from the outgoing interface of the configured
route. So, we need to find routes on other interfaces on reconfiguring
or so.
By this change, the limit of the number of routes per-interface is
tentatively dropped. Let's re-introduce the limit later in a nicer way.
When an address with peer address is specified, the kernel by default
adds the prefix route for the peer address. When ManageForeignRoute=no
is set, then we also needs to check the prefix for the peer address.
Fixes#30403.
Otherwise, we may configure a route that depends on the existence
of an address or another route, and may fail when lifetime of one
of them are already zero.
Hopefully fixes#28358.
IN C23, thread_local is a reserved keyword and we shall therefore
do nothing to redefine it. glibc has it defined for older standard
version with the right conditions.

Move the definition to missing_threads.h like the way we define e.g.
missing syscalls or missing definitions, and include it by the users.
