I/o scheduling the position of i/o schedulers (center) within various layers of the linux kernel 's storage stack Input/output (i/o) scheduling is the method that computer operating systems use to decide in which order i/o operations will be submitted to storage volumes I/o scheduling is sometimes called disk scheduling. The Linux Kernel/Storage The Linux Kernel/Print version Usage on fi.wikipedia.org Linux (ydin) Usage on fr.wikipedia.org Ordonnancement d'E/S Usage on hu.wiktionary.org Linux storage stack Usage on it.wikipedia.org NVM Express Usage on mk.wikipedia.org Влез/Излез (I/O) распоредувач Usage on pt.wikipedia.org NVM Express Logical volumes can suffer from external fragmentation when the underlying storage devices do not allocate their pes contiguously These attacks rely on some part of memory, usually the stack, being both writable and executable
If it is not, the attack fails. A stack buffer overflow can be caused deliberately as part of an attack known as stack smashing If the affected program is running with special privileges, or accepts data from untrusted network hosts (e.g A webserver) then the bug is a potential security vulnerability.
