Oh, solved!! \o/ Don't know why, but it didn't take correctly PROT_NONE flag on (userspace) mmap. with: mmapped_ptr = mmap(NULL,SIZE,PROT_READ, MAP_SHARED ,fd,0); ( or PROT_WRITE, or both) it works. thanks. -- -gaspa- ----------------------------------------------- -------- https://launchpad.net/~gaspa --------- ------ HomePage: iogaspa.altervista.org ------- -Il lunedi'dell'arrampicatore: www.lunedi.org - -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
