Insight
Insight
UNIX-domain sockets, also known as local sockets, are a mechanism for interprocess communication. They are similar to Internet sockets (and utilize the same system calls) but instead of relying on IP addresses and port numbers, UNIX-domain sockets have addresses in the local file system address space. When a UNIX-domain socket is attached to a location using the bind(2) system call, the length of the provided path is not validated. Later, when this address was returned via other system calls, it is copied into a fixed-length buffer.
