The stack trace code\ncalled back into RCU which then called the stack trace again.\n\nExpand the ftrace recursion protection to add a set of bits to protect\nevents from recursion. Each bit represents the context that the event is\nin (normal, softirq, interrupt and NMI).\n\nHave the stack trace code use the interrupt context to protect against\nrecursion.\n\nNote, the bug showed an issue in both the RCU code as well as the tracing\nstacktrace code. This only handles the tracing stack trace side of the\nbug. The RCU fix will be handled separately."},{"lang":"es","value":"En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nrastreo: Añadir protección contra recursión en la grabación de trazas de pila del kernel\n\nSe informó de un error sobre una recursión infinita causada por el rastreo de los eventos rcu con el disparador de traza de pila del kernel habilitado. El código de traza de pila volvió a llamar a RCU, que luego volvió a llamar a la traza de pila.\n\nExpandir la protección contra recursión de ftrace para añadir un conjunto de bits para proteger los eventos de la recursión. Cada bit representa el contexto en el que se encuentra el evento (normal, softirq, interrupción y NMI).\n\nHacer que el código de traza de pila use el contexto de interrupción para proteger contra la recursión.\n\nNota, el error mostró un problema tanto en el código RCU como en el código de traza de pila de rastreo.
