 .SS IPC namespaces (CLONE_NEWIPC)
-IPC namespaces isolate certain IPC resources,
-namely, System V IPC objects (see
-.BR sysvipc (7))
-and (since Linux 2.6.30)
-.\" commit 7eafd7c74c3f2e67c27621b987b28397110d643f
-.\" https://lwn.net/Articles/312232/
-POSIX message queues (see
-.BR mq_overview (7)).
-The common characteristic of these IPC mechanisms is that IPC
-objects are identified by mechanisms other than filesystem
-pathnames.
-.PP
-Each IPC namespace has its own set of System V IPC identifiers and
-its own POSIX message queue filesystem.
-Objects created in an IPC namespace are visible to all other processes
-that are members of that namespace,
-but are not visible to processes in other IPC namespaces.
-.PP
-The following
-.I /proc
-interfaces are distinct in each IPC namespace:
-.IP * 3
-The POSIX message queue interfaces in
-.IR /proc/sys/fs/mqueue .
-.IP *
-The System V IPC interfaces in
-.IR /proc/sys/kernel ,
-namely:
-.IR msgmax ,
-.IR msgmnb  ,
-.IR msgmni ,
-.IR sem ,
-.IR shmall ,
-.IR shmmax ,
-.IR shmmni ,
-and
-.IR shm_rmid_forced .
-.IP *
-The System V IPC interfaces in
-.IR /proc/sysvipc .
-.PP
-When an IPC namespace is destroyed
-(i.e., when the last process that is a member of the namespace terminates),
-all IPC objects in the namespace are automatically destroyed.
-.PP
-Use of IPC namespaces requires a kernel that is configured with the
-.B CONFIG_IPC_NS
-option.
