* network: NetLabel integrationTopi Miettinen2022-08-291-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New directive `NetLabel=` provides a method for integrating static and dynamic network configuration into Linux NetLabel subsystem rules, used by Linux Security Modules (LSMs) for network access control. The label, with suitable LSM rules, can be used to control connectivity of (for example) a service with peers in the local network. At least with SELinux, only the ingress can be controlled but not egress. The benefit of using this setting is that it may be possible to apply interface independent part of NetLabel configuration at very early stage of system boot sequence, at the time when the network interfaces are not available yet, with netlabelctl(8), and the per-interface configuration with systemd-networkd once the interfaces appear later. Currently this feature is only implemented for SELinux. The option expects a single NetLabel label. The label must conform to lexical restrictions of LSM labels. When an interface is configured with IP addresses, the addresses and subnetwork masks will be appended to the NetLabel Fallback Peer Labeling rules. They will be removed when the interface is deconfigured. Failures to manage the labels will be ignored. Example: ``` [DHCPv4] NetLabel=system_u:object_r:localnet_peer_t:s0 ``` With the above rules for interface `eth0`, when the interface is configured with an IPv4 address of 10.0.0.123/8, `systemd-networkd` performs the equivalent of `netlabelctl` operation ``` $ sudo netlabelctl unlbl add interface eth0 address:10.0.0.0/8 label:system_u:object_r:localnet_peer_t:s0 ``` Result: ``` $ sudo netlabelctl -p unlbl list ... interface: eth0 address: 10.0.0.0/8 label: "system_u:object_r:localnet_peer_t:s0" ... ```

* network: dhcp6: re-introduce RapidCommit= settingYu Watanabe2022-07-221-0/+13
| | | | | | | | | | | Previous implementation of disabling rapid commit was broken, and dropped by 308d01f3c4decf3240ca0c6c7f91049953df7299. Let's re-introduce the option in the correct way, as some servers seem to return borked message when the solicit message contain the rapid commit option. Closes #24065.

* Revert "networkd: NetLabel integration"Yu Watanabe2022-06-221-54/+0
| | | | | | | | | | | | | | This reverts PR #23269 and its follow-up commit. Especially, 2299b1cae32c1fb8911da0ce26efced68032f4f8 (partially), and 3cf63830acdef9d8afdc9ef1cf25aa7e85a5e4d5. The PR was merged without final approval, and has several issues: - The NetLabel for static addresses are not assigned, as labels are stored in the Address objects managed by Network, instead of Link. - If NetLabel is specified for a static address, then the address section will be invalid and the address will not be configured, - It should be implemented with Request object, - There is no test about the feature.

| | | | | | | | | | | | | | | | | | | | | | | | This reverts PR #22587 and its follow-up commit. More specifically, 2299b1cae32c1fb8911da0ce26efced68032f4f8 (partially), e176f855278d5098d3fecc5aa24ba702147d42e0, ceb46a31a01b3d3d1d6095d857e29ea214a2776b, and 51bb9076ab8c050bebb64db5035852385accda35. The PR was merged without final approval, and has several issues: - OSS fuzz reported issues in the conf parser, - It calls synchrnous netlink call, it should not be especially in PID1, - The importance of NFTSet for CGroup and DynamicUser may be questionable, at least, there was no justification PID1 should support it. - For networkd, it should be implemented with Request object, - There is no test for the feature. Fixes #23711. Fixes #23717. Fixes #23719. Fixes #23720. Fixes #23721. Fixes #23759.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New directive `NetLabel=` provides a method for integrating dynamic network configuration into Linux NetLabel subsystem rules, used by Linux security modules (LSMs) for network access control.

* network: clarify the relationship between DHCP= and WithoutRA=Alex Henrie2022-05-061-3/+4
| | | | | Just setting DHCP=ipv6 is not enough to get DHCPv6 working without RA. The WithoutRA option must also be changed from its default of "no".
* network: clarify the relationship between RA flags and DHCPv6 modesAlex Henrie2022-05-061-7/+12
| | | | | | | | | | | | | | | | | | In the documentation, using the term "managed" for both the RA flag and the DHCPv6 mode is confusing because the mode is referred to as "solicit" both in the official DHCPv6 documentation (see RFC 8415) and in the WithoutRA option. Furthermore, calling the other RA flag "other information" or "other address configuration" is confusing because its official name is simply "other configuration" (see RFC 4861 and RFC 5175) and it isn't used to assign IP addresses. Rewrite the documentation for DHCPv6Client and WithoutRA to make it clear that getting the "managed" RA flag triggers the same kind of DHCP request as WithoutRA=solicit, whereas getting the "other configuration" RA flag triggers the same kind of DHCP request as WithoutRA=information-request.

But still users needed to explicitly set a timespan. This makes networkd automatically determine the timeout when the situations #18738 or #19832 is detected. Unfortunately, still users have issue #20887 need to specify a value. Closes #19832.

When Isolated is not specified, the port uses the kernel default setting (false). The "Isolated" parameter was introduced in Linux 4.19. See man bridge(8) for more details. But even though the kernel and bridge/iproute2 recognize the "Isolated" parameter, systemd-networkd did not have a way to set it.
