Summary
In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix soft lockups in fib6_select_path under high next hop churn Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the `bird` service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the `fib6_select_path` function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer. Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs. Include a test script that reproduces the issue. The script periodically updates the routing table while generating a heavy load of outgoing IPv6 traffic through multiple iperf3 clients. It consistently induces infinite soft lockups within a couple of minutes.

Se han observado bloqueos suaves en un cl\u00faster del routeres de borde basados en Linux ubicados en un entorno altamente din\u00e1mico. Al usar el servicio `bird`, estos routeres actualizan continuamente las rutas anunciadas por BGP debido a que cambian con frecuencia los destinos del siguiente salto, al mismo tiempo que administran un tr\u00e1fico IPv6 significativo. Los bloqueos ocurren durante el recorrido de la lista enlazada circular de m\u00faltiples rutas en la funci\u00f3n `fib6_select_path`, particularmente mientras se itera a trav\u00e9s de los hermanos en la lista. El problema generalmente surge cuando los nodos de la lista enlazada se eliminan inesperadamente de manera concurrente en un n\u00facleo diferente, lo que se indica mediante sus elementos \u0027next\u0027 y \u0027previous\u0027 que apuntan al nodo mismo y su recuento de referencia cae a cero. Esto da como resultado un bucle infinito, lo que lleva a un bloqueo suave que desencadena un p\u00e1nico del sistema a trav\u00e9s del temporizador de vigilancia. Aplique primitivas RCU en las secciones de c\u00f3digo problem\u00e1ticas para resolver el problema. Cuando sea necesario, actualice las referencias a fib6_siblings para anotar o usar las API de RCU. Incluya un script de prueba que reproduzca el problema. El script actualiza peri\u00f3dicamente la tabla de enrutamiento mientras genera una gran carga de tr\u00e1fico IPv6 saliente a trav\u00e9s de varios clientes iperf3.
