catborise 680dd5dad4 fix(interfaces): interface changes roll back as one, a running one is not deleted, each interface is read once ... Plan reviewed with Codex; tried on a udev host (AlmaLinux 10) and a netcf one (AlmaLinux 8). - Changes are one change of the host's configuration (libvirt's interface change transaction): a bridge that does not start used to be undefined, leaving its member without the addresses and start mode the bridge took from it; now the whole change rolls back, the member's own configuration too, and so does a commit libvirt refuses. A rollback that fails too is reported with the failure, saying the host's configuration may be changed. Deleting a bridge, which defines its members again on their own, is one change as well. - A running interface is not deleted: the page hid Delete, but a post deleted it. A bridge with addresses and several members is refused (which member takes the addresses is the user's choice); the confirmation says that its members are defined again. - A bridge takes only a device in no bridge, bond or VLAN as the host has them configured, at any depth (a bridge's bond's devices), not the loopback, a libvirt network's bridge or a VM's tap; an ethernet interface configures only such a device too. - Whether the host can change interfaces: unsupported or refused by its access rules is a no, bad XML a yes, anything else (the connection, the login) is raised instead of taken for a yes. A page whose host could not be read offers no actions. - Reads: the list reads each interface's XML once from one listing (listAllInterfaces: every state, not the active and the defined ones apart); a page reads the running and the saved definition once each (cached_property). netcf writes a link speed of -1 for a card that has none (a virtio one) and then refuses its own XML: the saved one is read instead, where virsh and the page failed. Name and MAC come from libvirt's object, without a call. Each family says how it is addressed (DHCP, autoconf, static or none) and every address, its prefix where it has one; no address is not "DHCP" any more. A bridge's members carry their link state and speed; an unknown speed (0, -1, 4294967295) is none. - The interface API lists from the same reader. get_details, get_bridge, get_bridge_slave_ifaces and the per-family getters go.		2026-10-29 10:09:40 +03:00
