A Berkeley socket is an application programming interface (API) for Internet domain sockets and Unix domain sockets, used for inter-process communication (IPC). It is commonly implemented as a library of linkable modules. It originated with the 4.2BSD Unix operating system, which was released in 1983.
It was developed at the University of California, Berkeley, designed by Thomas Anderson, and is used by numerous schools around the world. Originally written in C++ for MIPS, Nachos runs as a user-process on a host operating system. A MIPS simulator executes the code for any user programs running on top of the Nachos operating system.
Linux includes a BPF JIT compiler which is disabled by default. Kernel-mode interpreters for that same virtual machine language are used in raw data link layer mechanisms in other operating systems, such as Tru64 Unix, and for socket filters in the Linux kernel and in the WinPcap and Npcap packet capture mechanism.
In computing, language primitives are the simplest elements available in a programming language. A primitive is the smallest 'unit of processing' available to a programmer of a given machine, or can be an atomic element of an expression in a language. Primitives are units with a meaning, i.e., a semantic value in the language.
However, the compiler automatically transforms the code so that the list will "silently" receive objects, while the source code only mentions primitive values. For example, the programmer can now write list . add ( 3 ) and think as if the int 3 were added to the list; but, the compiler will have actually transformed the line into list . add ...
Berkeley's Unix was the first Unix to include libraries supporting the Internet Protocol stacks: Berkeley sockets. A Unix implementation of IP's predecessor, the ARPAnet's NCP, with FTP and Telnet clients, had been produced at the University of Illinois in 1975, and was available at Berkeley.
eBPF is a technology that can run programs in a privileged context such as the operating system kernel. [5] It is the successor to the Berkeley Packet Filter (BPF, with the "e" originally meaning "extended") filtering mechanism in Linux and is also used in non-networking parts of the Linux kernel as well.
Sleepycat distributed Berkeley DB under a proprietary software license that included standard commercial features, and simultaneously under the newly created Sleepycat License, which allows open source use and distribution of Berkeley DB with a copyleft redistribution condition similar to the GNU General Public License.
