Title
bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error For all non-tracing helpers which formerly had ARG_PTR_TO_{LONG,INT} as input arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, it is not needed given CAP_PERFMON can already read all kernel memory anyway hence bpf_get_func_arg() and bpf_get_func_ret() is skipped in here. Also, the MTU helpers mtu_len pointer value is being written but also read. Technically, the MEM_UNINIT should not be there in order to always force init. Removing MEM_UNINIT needs more verifier rework though: MEM_UNINIT right now implies two things actually: i) write into memory, ii) memory does not have to be initialized. If we lift MEM_UNINIT, it then becomes: i) read into memory, ii) memory must be initialized. This means that for bpf_*_check_mtu() we're readding the issue we're trying to fix, that is, it would then be able to write back into things like .rodata BPF maps. Follow-up work will rework the MEM_UNINIT semantics such that the intent can be better expressed. For now just clear the *mtu_len on error path which can be lifted later again.

Para el seguimiento, no es necesario dado que CAP_PERFMON ya puede leer toda la memoria del kernel de todos modos, por lo tanto, bpf_get_func_arg() y bpf_get_func_ret() se omiten aqu\u00ed. Adem\u00e1s, el valor del puntero mtu_len de los ayudantes de MTU se escribe pero tambi\u00e9n se lee.

Si eliminamos MEM_UNINIT, se convierte en: i) lectura en memoria, ii) la memoria debe inicializarse. Esto significa que para bpf_*_check_mtu() estamos agregando nuevamente el problema que estamos tratando de solucionar, es decir, entonces podr\u00eda volver a escribir en cosas como mapas BPF .rodata. El trabajo de seguimiento reelaborar\u00e1 la sem\u00e1ntica de MEM_UNINIT de modo que la intenci\u00f3n pueda expresarse mejor.
