T8188: Preserve static IPv4 addresses flushed by dhclient

2026-03-19T16:07:08+00:00

When dhclient renews/rebinds a lease, it calls "ip -4 addr flush dev ". This removes ALL IPv4 addresses, including static addresses configured via VyOS (e.g., "set interfaces ethernet eth0 address 192.168.1.1/24"). The updated hook logic now intercepts the "ip -4 addr flush" command and replaces it with a selective flush that only removes addresses marked as "dynamic" by the kernel. DHCP-assigned addresses have the "dynamic" flag set automatically.

T5811: Make static dhcp-interface routes robust

2025-10-21T16:57:40+00:00

Solves the problem that vyos-configs in FRRender caches configuation and DHCP changes are ignored. * Add src/helpers/vyos-request-configd-update.py that requests vyos-configd to update FRR configuration. * Make dhclient hooks use it instead of calling protocols_static.py * Make FRRender cache not only configuration but also DHCP gateways so that is any of them changes, FRR configuration is updated

T7941: fix DHCP client running in VRF with non-word characters

2025-10-18T11:19:10+00:00

The previous implementation used awk with a regex to extract the VRF name from JSON data, relying on "(\w+)" to match the value. This broke for valid VRF names containing hyphens or other non-word characters. This update replaces the regex-based extraction with a jq query that reliably parses the JSON structure, ensuring correct behavior regardless of VRF name format. This also reduces parsing fragility by using a tool purpose-built for JSON processing.

dhclient: T6667: Added workaround for communication with FRR

2024-08-24T08:06:39+00:00

To increase the chance for dhclient to configure routes in FRR, added a workaround. Now 10 attempts are performed with 1 second delay and only after this dhclient gives up.

dhcpv6-client: T2590: fix vyos-hostsd update for nameserver and search domains

2024-04-01T12:04:50+00:00

After migrating from ISC DHCLIENT for IPv6 to wide-dhcp-client the logic which was present to update /etc/resolv.conf with the DHCP specified nameservers and also the search domain list was no longer present. This commit adds a per interface rendered script to inform vyos-hostsd about the received IPv6 nameservers and search domains.

dhclient: T5724: run user hooks using run_hookdir

2023-11-11T10:00:34+00:00

User hooks are executed using run_hookdir (defined in the /sbin/dhclient-script script) instead of run-parts. That allows user hooks to modify variables set by the dhcp client (e.g., the new_routers variable to avoid the installation of the default routes).

T4997: add dhcp client user hooks

2023-02-26T20:05:56+00:00

This commit adds a script to run user-defined hook scripts upon renewing a DHCP lease. This can be used to, for example, dynamically define a firewall address-group based on the dynamic IP address of an interface. For an example of its use (as well as the use case I had in mind while coding this), see https://vyos.dev/T2196#142394 Co-authored-by: br
