Yu Watanabe 562729d744 network/netdev: introduce .is_ready_to_create() entry in netdev vtable 2021-12-12 13:41:39 +09:00
Yu Watanabe 54cd4bb7c7 network: make activation error critical 2021-12-12 03:05:15 +09:00
Zbigniew Jędrzejewski-Szmek dc79ae23fb Merge pull request #21664 from yuwata/network-tunnel-cleanups 
network: several cleanups for tunnel device
 2021-12-11 17:17:40 +01:00
Jonas Jelten 3abdd4bf2e network-generator: support link6 network configuration 
this just brings up an interface in order to have IPv6 link local
connectivity.
 2021-12-11 11:03:42 +09:00
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.
 2021-12-10 18:42:34 +09:00
Yu Watanabe b55093ce88 network: dhcp: make IPServiceType= accept "none" to disable tos in the outgoing packet 
Fixes #9874.
 2021-12-09 15:06:20 +01:00
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 01081e2eab Merge pull request #21692 from yuwata/network-wireguard-allow-to-start-ndisc-or-radv 
network: wireguard: allow to start ndisc or radv

Yu Watanabe d2d602f4b4 network: refuse empty or numeric route table names 2021-12-09 09:06:41 +01:00
Yu Watanabe e096cab2f3 network: wireguard: allow to run NDisc and RADV when IPv6LL address is manually configured 
Fixes #17380.
 2021-12-09 15:57:47 +09:00
Yu Watanabe 78ef25a5aa network: address: add scope in debugging logs 2021-12-09 15:28:06 +09:00
Yu Watanabe 20228b6d96 network: address: also adjust scope when address is link local address 
But again only when Scope= is not explicitly specified.
 2021-12-09 15:25:19 +09:00
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.
 2021-12-09 15:25:05 +09:00
Yu Watanabe 72fa19239d network: route: mask lower bits of destination or source prefix 
Let's gracefully handle user's misconfiguration, e.g.
Destination=192.168.0.1/24
 2021-12-09 07:02:59 +09:00
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 
Similar fix to b489d6a26e.
 2021-12-09 06:52:01 +09:00

Fixes #21685.
 2021-12-09 03:04:24 +09:00
Yu Watanabe da94e4ddf5 network: wifi: ssid may be NULL

systemd-networkd[888]: wlan0: nl80211: received new_interface(7) message: iftype=station, ssid=(null)
 2021-12-09 02:43:29 +09:00
Yu Watanabe bb916f350a network: call link_check_ready() when all stacked netdevs are created 
Follow-up for 879377cad5.

Otherwise, the underlying interface may stuck in configuring state.
 2021-12-08 18:40:13 +09:00
Yu Watanabe 8ed68422e1 network: address: read flags from message header when IFA_FLAGS is not supported by kernel 
Follow-up for 0828a38605.

Fixes #21670.
 2021-12-08 05:40:09 +09:00
Yu Watanabe f14a6e7f48 network: route: tighten variable scope

Yu Watanabe e49bad0179 network: dhcp-pd: add 6rd support 
Closes #19152.
 2021-12-07 20:33:16 +09:00
Yu Watanabe 63dc602570 network: introduce link_remove() 2021-12-07 20:32:02 +09:00
Yu Watanabe a27588d4e7 network: dhcp-pd: rename [DHCPv6PrefixDelegation] -> [DHCPPrefixDelegation] 
This just changes the names of settings, variables, functions, files, and so on.
No functionality is changed.

Preparation for supporting 6rd.

Yu Watanabe 57c107544d network: fix memleak 
Follow-up for ab106a609b.

Fixes CID#1467055.
 2021-12-07 19:43:31 +09:00
Yu Watanabe 11d8a83f53 network: dhcp6pd: drop link_has_preferred_subnet_id() and inline condition 2021-12-07 19:43:06 +09:00
Yu Watanabe 557e1b5249 network: dhcp6pd: use the kernel's default value for priority of unreachable route 
This should not change any behavior, as both values are equivalent.
 2021-12-07 18:35:30 +09:00
Yu Watanabe 2d00239cbe network: dhcp6pd: always use main route table for unreachable route 
This mostly reverts e47bcb7d0b.

Yu Watanabe 543240f593 network/netdev: drop spurious state from the condition to create stacked netdevs 
Stacked netdevs are requested when the underlying interface is in
configuring state.
 2021-12-07 15:58:25 +09:00
Yu Watanabe f7144e7b0f network/netdev: create stacked netdevs after all set-link operations are finished 
E.g. setting MAC address must be done before creating VLAN interface.
 2021-12-07 15:58:25 +09:00
Yu Watanabe 879377cad5 network: do not block configuring addresses by creating stacked netdevs 
`link_is_ready_to_configure()` is used to judge we can configure
addresses, routes, and etc. And they can be configured independently of
stacked netdevs.
 2021-12-07 15:58:25 +09:00
Yu Watanabe 5329a37935 network: set MAC address before enslaving to bond or bridge interface 
As the master interface may inherit the slave MAC address.
 2021-12-07 15:58:25 +09:00
Yu Watanabe 45aa0e841b network,udev: do not adjust local assignment bit of specified MAC address 
People often assigns the MAC address of the enslaved interface to e.g.
bridge interface. So, the local assignment bit should not be adjusted.

Fixes #21649.
