Yu Watanabe ab106a609b network: eui64 address is supported only ethernet or infiniband 
So, this makes prefixstable mode will be used for other interface types.

Yu Watanabe d5ebcf6533 network: split networkd-dhcp6.c 
This moves DHCPv6 prefix delegation related functions to

Yu Watanabe cf477495d6 network: route: handle null address with non-zero prefixlen correctly 
Previously, even if a link has a route to e.g. ::/96, default gateway
via ::1.2.3.4 cannot be configured.

Yu Watanabe 8feb9fa4f8 Merge pull request #21584 from yuwata/network-wireguard-cleanups 
network: cleanups for wireguard
 2021-12-02 15:53:57 +09:00
Yu Watanabe 4a410adae6 Revert "network: address: drop deprecated temporary address" 
This reverts commit 528da64a0c.

The commit is a bad way to fix #19838, and introduces #21593.

Fixes #21593.

Yu Watanabe 38ef464e41 network/wireguard: search valid address of the endpoint from all struct addrinfo entries 2021-12-02 08:39:37 +09:00
Yu Watanabe 8bf7e3b61c network/wireguard: cleanups for resolving endpoints 
This makes
- drop peers_with_unresolved_endpoint and peers_with_failed_endpoint,
- drop destroy handler for sd_resolve_query, and manage each query by peer,
- add random fluctuation to the timeout for retry handler,
- retry timer event source is now managed by peer,
- use sd_event_source_disable_unref().
 2021-12-02 08:39:32 +09:00
Yu Watanabe 4a897d29f1 network/wireguard: do not resolve Endpoint= if an IP address is specified 
Also verify the domain name and port.

Yu Watanabe 1a4ca0e2f3 network: dhcp6-pd: exclude all explicitly specified subnet IDs when searching free IDs 
When the upstream link gained a lease, then several downstream links may
not appear yet. Previously, the explicitly specified subnet ID for a
downstream link which appears later may be already assigned to an
interface which does not request specific subnet ID.

To avoid such situation, this makes all specified IDs are excluded when
searching free IDs.

As a side effect, we can avoid the second call of
dhcp6_pd_distribute_prefix().

Yu Watanabe 9e11bd58fb network/wireguard: drop unnecessary .in6 specifier 
This should not change any behavior, as the size of the IPv4 address is
smaller than IPv6.

Yu Watanabe 5e82a61375 network: route: read RTA_TABLE attribute to get route table 
If the table of a route is larger than 255, then the value is stored in
RTA_TABLE attribute. But the attribute is not supported by old kernels.
So, first try to read the value from RTA_TABLE attribute, then fallback
to the value in the message header.

Zbigniew Jędrzejewski-Szmek 67b65e1104 networkd: replace a table with log2 fields by a list 
The code looks a bit more complicated, but the compiler generates a simpler and
more compact text.

An additional advantage is that if any of the fields were repeating or not
power-of-two, the compiler would warn about an overridden entry in the table.

Yu Watanabe 5b8bdd20c6 network/netdev: generate persistent MAC address for batadv and bridge 
This mostly reverts 489f01f806 and
deb2cfa4c6.

As now MACAddress=none is supported. So, users can still disable MAC
address assignment.
 2021-11-28 12:04:55 +09:00
Yu Watanabe aaa5ca57ae network/netdev: make MACAddress= take 'none' to suppress generating persistent hardware address 
This is mostly equivalent to .link file's MACAddressPolicy=none.

Yu Watanabe 007899f43e network/netdev: verify specified MAC address 
Drop multicast bit and set local bit of the specified MAC address.

This also makes failure in generating persistent MAC address
non-critical.
