* dhcp: introduce sd_dhcp_duid and move relevant functions to sd_dhcp_duid.[ch]Yu Watanabe2023-12-221-1/+1
|
* network: introduce SendHostname/Hostname DHCPv6 optionsRonan Pigott2023-10-301-0/+1
| | | | | These options were previously reused by the DHCPv6 client from the DHCPv4 client settings. Let's separate them for consistency.
* network/dhcp: fix maximal DUID data sizeYu Watanabe2023-08-241-1/+1
| | | | | The maximum DUID size is 128, but that includes type specified. Hence, the maximal data size is 126.
* network: introduce link_get_captive_portal()Yu Watanabe2023-07-061-0/+2
| | | | | Then, downgrade log level of the message about mis-match of captive portals in different protocols.
* network: adjust route priority based on preferenceYu Watanabe2022-10-281-1/+5
| | | | | | | | Even if different preference is specified, the kernel merges multiple routes with the same preference. This is problematic when a network has multiple routers. Fixes #25138.
* network: dhcp6pd: always use main route table for unreachable routeYu Watanabe2021-12-071-1/+0
| | | | This mostly reverts e47bcb7d0b2cb07c5c594e374baeb061bb7f88ba.
* network: dhcp6: introduce UplinkInterface= for DHCP6 prefix delegationYu Watanabe2021-10-261-0/+1
|
* network: move config_parse_uplink() to networkd-dhcp-common.[ch]Yu Watanabe2021-10-261-0/+5
|
* network: dhcp6pd: set default metric 256 for delegated prefixYu Watanabe2021-10-191-0/+1
| | | | | | | | | | | When Assign= in [DHCPv6PrefixDelegation] is enabled, then the kernel will create the prefix route for the assigned address with metric 256. When Assign= is disabled, then the kernel will create the route with metric 1024. For the default value, we should choose a smaller value (higher priority) than 1024, as the unreachable routes for delegated prefix will be configured with 1024.
* network: replace config_parse_address_filter() with ↵Yu Watanabe2021-09-141-1/+0
| | | | config_parse_in_addr_prefixes()
* network: do not use RouteTable= in [DHCPv4] section for DHCPv6 routesYu Watanabe2021-09-141-1/+5
| | | | | We forgot to add RouteTable= in [DHCPv6] section when we split [DHCP] into two.
* network: use ltype to distinguish DHCPv4 and DHCPv6Yu Watanabe2021-09-141-1/+1
|
* network: dhcp4,ndisc: make addresses in Allow/DenyList= optionally take ↵Yu Watanabe2021-08-231-0/+11
| | | | | | prefix length Closes #20505.
* network: dhcp: constify link_get_duid()Yu Watanabe2021-04-211-4/+4
|
* network: configure non-dhcp configs earlier even DUID-UUID is used by DHCP ↵Yu Watanabe2021-04-211-1/+1
| | | | | | | | | | clients Previously, if DUID-UUID is used, all configurations are configured after networkd gets product uuid of machine. This makes only DHCP clients are delayed, and other configs are configured earlier.
* network: make IAID and DUID for DHCPv6 configurable explicitlyYu Watanabe2021-04-211-2/+14
| | | | Closes #18996.
* network: move dhcp related conf parsers to networkd-dhcp-common.cYu Watanabe2021-04-211-0/+4
|
* tree-wide: use -EINVAL for enum invalid valuesZbigniew Jędrzejewski-Szmek2021-02-101-1/+1
| | | | | | | | | As suggested in https://github.com/systemd/systemd/pull/11484#issuecomment-775288617. This does not touch anything exposed in src/systemd. Changing the defines there would be a compatibility break. Note that tests are broken after this commit. They will be fixed in the next one.
* network: merge config_parse_dhcp_user_class() and _vendor_class()Yu Watanabe2021-01-121-2/+1
|
* license: LGPL-2.1+ -> LGPL-2.1-or-laterYu Watanabe2020-11-091-1/+1
|
* network: introduce network_adjust_dhcp()Yu Watanabe2020-10-151-0/+3
|
* network: move DUID related functionsYu Watanabe2020-10-061-0/+5
|
* network: unify link_dhcp{4,6}_enabled()Yu Watanabe2020-10-061-0/+10
|
* network: drop an unused functionYu Watanabe2020-06-021-1/+0
|
* network: move DHCPv6 related conf parsers to networkd-dhcp6.cYu Watanabe2020-06-021-2/+0
|
* network: set both dhcp_route_metric and dhcp6_route_metric by ↵Yu Watanabe2020-06-021-0/+1
| | | | | | | DHCP.RouteMetric= for backward compatibility But [DHCPv4] or [DHCPv6] section take precedence. This also update so for UseDNS= and UseNTP=.
