babeld: fix issues in the ubus bindings and the init script

2026-10-11T13:56:41Z

Fix the issues the Copilot review found in the code moved from the routing feed: - The init script wrote "option ignore '0'" of an interface section as "interface ignore false" into the babeld configuration, which babeld rejects. Skip the option like ifname. - The handlers of get_xroutes, get_routes and get_neighbours didn't check their allocations. Free the collected entries and return an error instead of crashing. - add_filter allocated and returned success for an invalid filter type and leaked the filter. Reject the type before the allocation, and handle a failure of strdup() and add_filter(). - babeld doesn't use uloop, so the default handler of libubus did nothing when ubusd restarted. The stale socket stayed readable and babeld spun in its select loop, and the babeld object was never added again. Reconnect from the main loop instead, waiting longer after each failed attempt, up to 32 seconds. ubus_reconnect() adds the object again. - The notifications used the helpers for array elements, so their fields were in an unnamed table. Put them at the root of the message. - Neighbour notifications were named neigh.*, while ubus.h documents neighbour.*. Use the documented names.

babeld: initialize metric in the ubus add_filter handler

2026-10-11T13:56:41Z

The metric is optional in filter_policy: only ifname and type are rejected when missing, so `ubus call babeld add_filter '{"ifname":"eth0","type":0}'` reaches filter->action.add_metric = metric; with metric never assigned, i.e. whatever was left on the stack. In babeld an add_metric of INFINITY means "deny", so an uninitialized read can silently turn an allow filter into a deny filter. Initialize it to 0, which is the neutral value the filter would have had if the caller had passed it explicitly.

babeld: add new package

2026-10-11T13:56:41Z

Babel is a loop-avoiding distance-vector routing protocol for IPv6 and IPv4 with fast convergence properties (RFC 8966). Moved from the openwrt/routing feed, as discussed in https://github.com/openwrt/routing/issues/184.
