* network: Restrict the valid charset of DNR namesRonan Pigott2024-10-291-0/+6
| | | | | | | | | Not all possible DNS names will survive serialization. Restrict the set of valid dns names to LDH encoded names. Fixes: 25c33e350042 (network: parse RFC9463 DHCPv4 DNR option, 2024-01-16) Fixes: a07e83cc58f6 (network: Parse RFC9463 DHCPv6 DNR option, 2024-01-17) Fixes: 0c90d1d2f243 (ndisc: Parse RFC9463 encrypted DNS (DNR) option, 2024-01-19)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts the following commits: - 180cc5421d9712fb95a6bbc725dc8ba459360c8b "sd-dhcp6-client: allow to request IA_PD on information requesting mode" - cf7a403e470368049165ecff7ac7686928778d7c "sd-dhcp6-lease: adjust information refresh time with lifetime of IA_PD" - 1918eda30d12e1ba3ee55921c18ec53267463e24 "network/dhcp6: process hostname and IA_PD on information requesting mode" As per discussion in #34299, https://github.com/systemd/systemd/issues/34299#issuecomment-2425153221 the offending commits violate RFC 8415 section 18.2.6: > The client uses an Information-request message to obtain > configuration information without having addresses and/or delegated > prefixes assigned to it.

| | | | | | | | | | Implement the parsing for V6_DNR DHCPv6 option. This does the same as the DHCP V4_DNR option.
* | sd-dhcp6-lease: adjust information refresh time with lifetime of IA_PDYu Watanabe2024-10-151-6/+29
| | | | | | | | For the case when IRT is too large but lifetime of IA_PD is too short.

* Rename {dual,triple}_timestamp_get to {dual,triple}_timestamp_nowZbigniew Jędrzejewski-Szmek2023-11-131-1/+1
| | | | | | Those functions take a pointer to a timestamp and return a timestamp pointer, so the reader would be justified to think that those are just getters. Rename them to avoid confusion.
* dhcp6: enterprise ID is 32bitYu Watanabe2023-11-011-1/+1
| | | | | | Follow-up for 6b44099b3baff64af1ef58db8e38ecddc8070e9b. Fixes #29800.
* networkd: Add DHCP vendor specific options to dbus APINandakumar Raghavan2023-10-271-0/+86
| | | | | | Add DHCP vendor specific options to expose in dbus API. This will be added to the JSON output when we query org.freedesktop.network1.Manager object.

* sd-dhcp6-client: rework IA_NA or IA_PD gettersYu Watanabe2023-09-201-26/+109
| | | | | | | | | This splits sd_dhcp6_lease_get_address() into small pieces, and introduce FOREACH_DHCP6_ADDRESS() macro. Also, the lifetimes provided by _get_address_lifetime() are now in usec, and _get_address_lifetime_timestamp() provides timestamp. The same change is also applied for IA_PD.
* sd-dhcp6-client: introduce sd_dhcp6_lease_has_pd_prefix() and friendYu Watanabe2023-09-201-0/+8
| | | | No functional change, just refactoring.

* | sd-dhcp6-lease: ignore invalid byte(s) at the end of the packetPhilipp Kern2023-06-291-0/+5
|/ | | | | | | | | | | | | | Oracle Cloud sends malformed DHCPv6 replies that have an invalid byte at the end, which cannot be parsed as an option code. networkd currently can cope with the invalid option (it is ignored), but the whole packet is ignored altogether because of the additional null at the end. It's better to be liberal in what we accept and actually assign an address, given that the reply contains a valid IA_NA. Fixes #28183.
* sd-dhcp6: always append the default status message generated from status codeYu Watanabe2023-01-161-4/+2

* dhcp6: gracefully handle NoBinding errorYu Watanabe2022-08-121-1/+1
| | | | | | | When we receive NoBinding status code, the requesting binding (address or any other information) does not exist anymore in the server. Hence, resending the request is meaningless. Let's restart the transaction from the beginning in that case.

| | | | Also, this moves string tables to dhcp6-protocol.c.

* sd-dhcp6-client: set lease expiration timer in client_enter_bound_state()Yu Watanabe2022-02-141-17/+10
| | | | | | The timer must be active until the client get re-enter bound state, and the timeout must be determined by the lease acquired when entering the bound state.
