Yu Watanabe 239f91f71c network: can: make Termination= optionally take a raw resistor value 
Note that this slightly breaks backward compatibility when
Termination=1. Previously, this is handled as boolean true, then 120 ohm
was used. But now with this commit, it is handled as 1 ohm.

Yu Watanabe ccffa166d8 network: use request queue to configure DHCP{4,6} clients 
Previously, when UUID is requested for DUID, then the clients are
configured in callback of bus methods.
But now, 'request queue' was implemented, so we can use it to wait until
the product UUID is obtained.

Yu Watanabe d09a179e69 network: reconfigure link after coming back from sleep 
Previously, link was reconfigured with `link_carrier_reset()`, but it
just re-request to configure static addresses, routes, etc, and restart
engines (e.g. DHCP client).
However, after coming back from sleep, several link information may be
changed, especially the wifi access point may be different. So, we may
need to reconfigure the interface.

Yu Watanabe 2d302d88e4 network: configure address with requested lifetime 
When assigning the same address provided by a dynamic addressing
protocol, the new lifetime is stored on Request::Address, but not
Address object in Link object, which can be obtained by address_get().
So, we need to configure address with Address object in Request.

Yu Watanabe 0ebab55f4f network: dhcp4: also support semi-static routes with Gateway=_dhcp4 when UseGateway=no or UseRoutes=no 
This makes the default gateway is read from classless static routes or
router option even if UseGateway=no or UseRoutes=no, and will be used
when configuring semi-static routes such that specified with Gateway=_dhcp4.

This also changes the behavior of RoutesToDNS= or RoutesToNTP=.
Previously, the DNS or NTP servers are not in the same network, then the
routes to the servers were not configured when UseGateway=no or
UseRoutes=no. With this commit, the default gateway in classless static
routes or router option will used to connecting the servers even if
UseGateway=no or UseRoutes=no.

Yu Watanabe 176b8be10f network: check the received interface name is actually new 
For some reasons I do not know, on interface renaming, kernel once send
netlink message with old interface name, and then send with new name.
If eth0 is renamed, and then new interface appears as eth0, then the
message with the old name 'eth0' makes the interface enters failed
state.

To ignore such invalid(?) rename event messages, let's confirm the
received interface name.

 2021-07-02 20:59:38 +09:00
Yu Watanabe fe139e8ef9 network: drop old ndisc configurations after new ones are configured 
Previously, `ndisc_remove_old_one()` checked `ndisc_{addresses,routes}_configured`
flags, but they are not unset when all addresses or routes are already
assigned.
After the request queue is implemented, the address or route requests
are not processed within the same event of ndisc handler is called, but
will processed later when they are ready. So, calling `ndisc_remove_old()`
in the event of ndisc handler will remove all addresses and routes
previously assigned even they are requested to be updated.

This makes `ndisc_remove_old()` do nothing when there exist some
requests to configure addresses and routes, thus previously assigned
addresses and routes are kept until all requests are processed.

Fixes #20050.
