Socket operation on non-socket EDESTADDRREQ: 89: Destination address required EMSGSIZE: 90: Message too long EPROTOTYPE: 91: Protocol wrong type for socket ENOPROTOOPT: 92: Protocol not available EPROTONOSUPPORT: 93: Protocol not supported ESOCKTNOSUPPORT: 94: Socket type not supported EOPNOTSUPP: 95: Operation not supported EPFNOSUPPORT: 96 ...
The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...
Typically, certain instructions are not permitted (especially those—including I/O operations—that could alter the global state of the machine), some memory areas cannot be accessed, etc. User-mode capabilities of the CPU are typically a subset of those available in kernel mode, but in some cases, such as hardware emulation of non-native ...
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1]
If the destination address was local, but referred to a user name not found in the local password file, the message sent back to the originator of the email was the announcement that the person they were attempting to communicate with was not a typewriter.
The applications are not permitted by the processor to address kernel memory, thus preventing an application from damaging the running kernel. This fundamental partition of memory space has contributed much to the current designs of actual general-purpose kernels and is almost universal in such systems, although some research kernels (e.g ...
An oops may precede a kernel panic, but it may also allow continued operation with compromised reliability. The term does not stand for anything, other than that it is a simple mistake. The term does not stand for anything, other than that it is a simple mistake.
In any given system design, some operations performed by the system may not be preemptable. This usually applies to kernel functions and service interrupts which, if not permitted to run to completion , would tend to produce race conditions resulting in deadlock .
