Lennart Poettering a99a85242c tree-wide: use config_parse_safe_string() at various places 2022-02-09 10:17:33 +01:00
Santa Wiryaman 97f27f8a16 Add support for isolated parameter 
Add the "Isolated" parameter in the *.network file, e.g.,

[Bridge]
Isolated=true|false

When the Isolated parameter is true, traffic coming out of this port
will only be forward to other ports whose Isolated parameter is false.

When Isolated is not specified, the port uses the kernel default
setting (false).

The "Isolated" parameter was introduced in Linux 4.19.
See man bridge(8) for more details.
But even though the kernel and bridge/iproute2 recognize the "Isolated"
parameter, systemd-networkd did not have a way to set it.

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.

not propagated to other interfaces.

Yu Watanabe b69bfa4305 network: do not remove localhost address 
Managing loopback interfaces by networkd is not recommended, but supporeted.
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.
