Yu Watanabe 13ffa39f8e network: rename network_verify_xxx() -> network_drop_invalid_xxx() 
As 'verify' implies a boolean result.

Yu Watanabe 494b6b43cb network: fix masquerade setting logic 
Previously, address_establish() took Address object stored in Network
object. And address_release() took Address object stored in Link
object. Thus, address_release() always did nothing.

Yu Watanabe cd1caf30c0 network: always use RT_SCOPE_HOST for IPv4 loopback addresses 
For IPv6 case, use RT_SCOPE_HOST only when scope is not explicitly specified.

Yu Watanabe d93d655c40 network: update MAC address in IPv4 ACD clients 
When the MAC address of a link is updated, an address on the link may
be under checking address duplication. Or, (currently such code is not
implemented yet, but) address duplication check may be restarted later.
For that case, the IPv4 ACD clients must use the new updated MAC address.

Yu Watanabe 490ccbd5e5 network: configure IPv4 DAD per link address 
Previously, IPv4 DAD is configured in each Address object stored in
Network object. If a .network file matches multipe links, then it causes
an assertion. To prevent it, now IPv4 DAD is configured in each Address
object belogs to Link object.

Yu Watanabe 9cd9fc8f44 network: drop list of static addresses 
[Address] sections are managed by both LIST and Hashmap. Let's drop the
list and manage them by OrderedHashmap.

Yu Watanabe 9a0ad16b26 network: update log messages 
And drop unnecessary log for in_addr_to_string(), as its result is used
only for the consequent logs.

Yu Watanabe 50550722e3 network: fix NDisc handling for the case when multiple routers exist 
69203fba70 does not consider the case that
multiple routers exist, and causes #16719.

Fixes #16719.

Yu Watanabe ea121d8f25 network: update address infomation even if link is in failed or linger state 
As the link may be reconfigured later. If we do not update the address
information, then its setup state or operstate may not be updated
correctly.
 2020-07-29 02:05:05 +09:00
Yu Watanabe e55265184b network: do not assume static addresses are configured 
link_request_set_routes() is also called when a dynamic address is
configured. At that time, static addresses may not be configured yet.

Fixes #16546.

Yu Watanabe 1633c45731 network: dhcp6: drop addresses and delegated prefixes on client stop 
Previously, we did not drop addresses and delegated prefixes when
DHCP6 client is stopped.

Fixes #15455.
Fixes #13564.

Yu Watanabe 69203fba70 network: ndisc: remove old addresses and routes after at least one SLAAC address becomes ready 
Otherwise, the old addresses will exist in deperecated state.
 2020-07-29 02:05:05 +09:00
Yu Watanabe 6e537f62d7 network: dhcp4: release old lease after the new address become ready 
Previously, on DHCPv4 address renewal, the old address may be removed
while the new address is not ready yet.

This also simplifies the logic of removing address and routes.

Zbigniew Jędrzejewski-Szmek de7fef4b6e tree-wide: use set_ensure_put() 
Patch contains a coccinelle script, but it only works in some cases. Many
parts were converted by hand.

Note: I did not fix errors in return value handing. This will be done separate
to keep the patch comprehensible. No functional change is intended in this
patch.

Zbigniew Jędrzejewski-Szmek 10b20e5a93 network: allow empty assignment to PreferredLifetime= 
Users might want to use that to unset a previous setting. The docs seem OK as
they are: we don't need to explictly mention the empty value, since it is
almost always allowed.
 2020-05-25 14:52:04 +02:00
Zbigniew Jędrzejewski-Szmek d273579667 network: use consistent type when parsing lifetimes 
Those fields are both uint32_t, so we should use the same type when parsing.
Having a different type didn't change the result, but let's be consistent.

Kevin P. Fleming 8a98f11ed0 network: Make address_hash_ops available outside of networkd-address.c 
In order to allow other parts of systemd-networkd to use sets/hashmaps
of Address objects, the address_hash_ops structure needs to be made
available to them.
