Yu Watanabe 8b1cfab962 network: do not restart DHCPv6 client when it is already running in managed mode 
Otherwise, if a network has two router and one provides M flag and the
other provides O flag, then the DHCPv6 client switches the running mode
repeatedly. That makes the IPv6 network configuration of the host
unstable.

Yu Watanabe 81db4f3dd8 network: drop managed configs on reconfigure when KeepConfiguration=yes 
Otherwise, the managed configs, that is addresses, routes and so on
configured by the previously assigned .network file will not be dropped
on reconfiguring the interface.

Yu Watanabe 07c160a65c network: drop redundant condition 
The function `link_drop_foreign_addresses()` is only called in
`link_drop_foreign_config()`, and the same condition is located in the
caller.

Joerie de Gram 77d65e5659 network: attempt to trigger kernel IPv6LL address generation 
Try to ensure kernel IPv6 link local address generation occurs by
setting the per-if addr_gen_mode sysctl when the link is already up,
instead of the netlink interface (IFLA_INET6_ADDR_GEN_MODE).

The netlink setting is sufficient in cases where the interface is not
yet up when networkd configures an interface - bringing the interface
up will trigger in-kernel address generation.

If the interface is already up, yet the interface has no IPv6LL assigned
setting IFLA_INET6_ADDR_GEN_MODE has no effect.

Writing the addr_gen_mode sysctl is a best effort attempt at triggering
address generation regardless of interface state because it also works
in cases where the interface is already up.

Fixes #22424.

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

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().
