Esto \u00faltimo ocurre, por ejemplo, cuando el usuario cambia el recuento de cola en una interfaz a trav\u00e9s de set_channels() de ethtool. Hay un problema relacionado con el recuento de bpf_prog cuando se reconstruye VSI: dado que se llama a ice_prepare_xdp_rings() con vsi-\u0026gt;xdp_prog como argumento que ice_vsi_assign_bpf_prog() usa m\u00e1s adelante, los mismos punteros de bpf_prog se intercambian entre s\u00ed. Luego tambi\u00e9n se interpreta como un \u0027old_prog\u0027 que a su vez hace que llamemos a bpf_prog_put, lo que disminuir\u00e1 su recuento. El siguiente s\u00edmbolo se puede interpretar de una manera que, debido al recuento cero de un bpf_prog, se elimina del sistema mientras el kernel todav\u00eda intenta hacer referencia a \u00e9l: [481.069429] ERROR: no se puede manejar el error de p\u00e1gina para la direcci\u00f3n: ffffc9000640f038 [481.077390] # PF: acceso de lectura de supervisor en modo kernel [ 481.083335] #PF: error_code(0x0000) - p\u00e1gina no presente [ 481.089276] PGD 100000067 P4D 100000067 PUD 1001cb067 PMD 106d2b067 PTE 0 [ 481.097141] : 0000 [#1] ANTICIPACI\u00d3N SMP PTI [ 481.101980] CPU: 12 PID: 3339 Comm: sudo Tainted: G OE 5.15.0-rc5+ #1 [ 481.110840] Nombre de hardware: Intel Corp.
