Descriptions

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to avoid potential panic during recovery

During recovery, if FAULT_BLOCK is on, it is possible that
f2fs_reserve_new_block() will return -ENOSPC during recovery,
then it may trigger panic.

Also, if fault injection rate is 1 and only FAULT_BLOCK fault
type is on, it may encounter deadloop in loop of block reservation.

Let's change as below to fix these issues:
- remove bug_on() to avoid panic.
- limit the loop count of block reservation to avoid potential
deadloop.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: f2fs: corrección para evitar un posible pánico durante la recuperación. Durante la recuperación, si FAULT_BLOCK está activado, es posible que f2fs_reserve_new_block() devuelva -ENOSPC durante la recuperación, lo que puede provocar pánico. Además, si la tasa de inyección de fallas es 1 y solo el tipo de falla FAULT_BLOCK está activado, es posible que se produzca un bucle muerto en el bucle de reserva de bloque. Cambiemos como se muestra a continuación para solucionar estos problemas: - elimine bug_on() para evitar el pánico. - limitar el número de bucles de reserva de bloques para evitar posibles bucles muertos.
