Yu Watanabe b1d9c504d3 network: wait until the DSA master interface becomes up 
This is for the DSA subsystem, which have several stacked interfaces
on the master interface. To bring up a stacked interface, it is necessary
that the master is already up. See
https://github.com/systemd/systemd/issues/7478#issuecomment-348508263.

Note this is not necessary for newer kernels which includes
https://github.com/torvalds/linux/commit/9d5ef190e5615a7b63af89f88c4106a5bc127974.

Fixes #7478.

Yu Watanabe 8a20a8438f network: route: link_drop_foreign_routes() must be called only for managed interfaces 2021-12-17 00:14:30 +09:00
Yu Watanabe f974f17ae7 networkd: check the existence of the route 2021-12-17 00:13:42 +09:00
Yu Watanabe a71c5c44f7 network: address: minor optimization for link_drop_foreign_addresses() 
link_address_is_dynamic() is costful in general. Call it only when
KeepConfiguration= is set.

Note, it is not necessary to check link->network in the loop, as we have
the assertion for that in the beginning of the function.

Zbigniew Jędrzejewski-Szmek 03f7ddf0bf meson: stop building out convenience libraries by default 
The meson default for static_library() are:
build_by_default=true, install=false. We never interact with the
static libraries, and we only care about them as a stepping-stone towards
the installable executables or libraries. Thus let's only build them if
they are a dependency of something else we are building.

While at it, let's drop install:false, since this appears to be the default.

This change would have fixed the issue with lib_import_common failing
to build too: we wouldn't attempt to build it.

In practice this changes very little, because we generally only declare static
libraries where there's something in the default target that will make use of
them. But it seems to be a better pattern to set build_by_default to false.

Jonas Jelten 3abdd4bf2e network-generator: support link6 network configuration

connectivity.

LaserEyess ea5e55b311 network: rename SetupState to AdministrativeState 
This is more consistent with the terminology used elsewhere. In
particular it is consistent with the name of the property exposed over
dbus for the link state.

Yu Watanabe b55093ce88 network: dhcp: make IPServiceType= accept "none" to disable tos in the outgoing packet 
Fixes #9874.

Yu Watanabe 71df07760e network: sd-ipv4ll and sd-ipv4acd only support ethernet interfaces 
The deny list in link_ipv4ll_enabled() are mostly non-ethernet type,
whose link->iftype are not ARPHRD_ETHER, e.g. ARPHRD_NONE for bareudp,
ARPHRD_WIREGURAD for wireguard, ARPHRD_GRE for gre, and so on.

Only the exception is vrf, which is ARPHRD_ETHER, but seems not to
support ARP.

Yu Watanabe 20228b6d96 network: address: also adjust scope when address is link local address 
But again only when Scope= is not explicitly specified.

Yu Watanabe 8f8dc32cc9 network: address: do not adjust user specified scope 
This reverts cd1caf30c0.

I cannot remember why such change was made.
At least, the kernel does not refuse to set IPv4 localhost address with
non-host scope, e.g. global.

Yu Watanabe e944711fba network: json: add src address when its prefix length is non-zero 
This should not change anything. Just for consistency with
route_set_netlink_message(), which sets RTA_SRC attribute when prefix
length is non-zero.
 2021-12-09 07:02:29 +09:00
Yu Watanabe 7cf0ed03f2 network: route: show prefix length of the source in debugging logs

Otherwise, the underlying interface may stuck in configuring state.
