2024-03-28dhcp: T6174: Add TACACS/Radius users to _kea groupsarthurdev
Also raise op-mode error when unable to fetch data from Kea socket
2024-03-28op-mode: T6175: "renew dhcp interface <name>" does not check for DHCP interfaceChristian Breunig
The current op-mode script simply calls sudo systemctl restart "dhclient@$4.service" with no additional information about a client interface at all. This results in useless dhclient processes root 47812 4.7 0.0 5848 3584 ? Ss 00:30 0:00 /sbin/dhclient -4 -d root 48121 0.0 0.0 4188 3072 ?

This commit moved the renew command to the DHCP op-mode script to properly validate if the interface we request a renew for, has actually a dhcp address configured. In additional this exposes the renew feature to the API.

* Add `clear dhcpv6-server lease` * Standardize using vyos.opmode

2024-02-13dhcpv6-server: T5992: Fix op-mode Kea DHCP lease outputsarthurdev
Due to Kea's lease file cleanup, the CSV file content is inconsistent. This commit makes changes to use the Kea control socket to fetch current lease information.

* Also migrate `address-range` to `range` tag node for consistency with dhcpv4 server syntax
2023-12-29dhcp: T3316: Adjust kea lease files' location and permissionsIndrajit Raychaudhuri
Move the kea lease file to a separate directory `/config/dhcp` that `kea` process can write to so that subprocesses spawned by `kea` process can operate on the lease files. To allow `kea` process to write to `/config/dhcp`, add `_kea` user to `vyattacfg` group. And the lease files are owned completely by `_kea` user to play well with `kea-lfc` process. Specifically, this is necessary for `kea-lfc` which is spawned by `kea` process to clean up expired leases. Since `kea-lfc` creates additional backup lease files, it needs write access to the lease file directory. Additionally, change the extension of the lease file from `.leases` to `.csv` to reflect the actual file format.

Multiple scripts use the same hardcoded path for DHCP client leases in different direcotries - this can't be worse.
2023-07-30T3355: always work with UNIX timestamps for dhcp client lease displayChristian Breunig
ISC dhcp client contains least_update timestamp in human readable format this makes less sense for an API and also the expiry timestamp is provided in UNIX time.

With long lease time for example lease '4294967295' seconds it is impossible to get end lease as value is 'ends never;' It cause error to get timestamp() from 'ends never' and remaining time 'lease.end - datetime.utcnow()' Set default remaining and end lease to '-' if we cannot get this info
