When a user does\nclone(CLONE_NEWIPC) or unshare(CLONE_NEWIPC), the unshare will cause an\ninternal mount of a new mqueuefs sb linked to the new ipc ns.\n\nWhen a user does \u0027mount -t mqueue mqueue /dev/mqueue\u0027, he mounts the\nmqueuefs superblock.\n\nPosix message queues can be worked with both through the mq_* system calls\n(see mq_overview(7)), and through the VFS through the mqueue mount.  Any\nusage of mq_open() and friends will work with the acting task\u0027s ipc\nnamespace.  Any actions through the VFS will work with the mqueuefs in\nwhich the file was created.  So if a user doesn\u0027t remount mqueuefs after\nunshare(CLONE_NEWIPC), mq_open(\"/ab\") will not be reflected in \"ls\n/dev/mqueue\".\n\nIf task a mounts mqueue for ipc_ns:1, then clones task b with a new ipcns,\nipcns:2, and then task a is the last task in ipc_ns:1 to exit, then (1)\nipc_ns:1 will be freed, (2) it\u0027s superblock will live on until task b\numounts the corresponding mqueuefs, and vfs actions will continue to\nsucceed, but (3) sb-\u003es_fs_info will be NULL for the sb corresponding to\nthe deceased ipc_ns:1.\n\nTo make this happen, we must protect the ipc reference count when\n\na) a task exits and drops its ipcns-\u003ecount, since it might be dropping\n   it to 0 and freeing the ipcns\n\nb) a task accesses the ipcns through its mqueuefs interface, since it\n   bumps the ipcns refcount and might race with the last task in the ipcns\n   exiting.\n\nSo the kref is changed to an atomic_t so we can use\natomic_dec_and_lock(\u0026ns-\u003ecount,mq_lock), and every access to the ipcns\nthrough ns \u003d mqueuefs_sb-\u003es_fs_info is protected by the same lock.\n\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Serge E.

As they are allocated in any cases for each new ipc_namespace, there\nis no gain of memory in having them allocated separately of the struct\nipc_namespace.\n\nThis patch proposes to make this table static in the struct ipc_namespace.\nThus, we can allocate all in once and get rid of all the code needed to\nallocate and free these ipc_ids separately.\n\nSigned-off-by: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nAcked-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nCc: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "namespaces: move the IPC namespace under IPC_NS option\n\nCurrently the IPC namespace management code is spread over the ipc/*.c files.\nI moved this code into ipc/namespace.c file which is compiled out when needed.\n\nThe linux/ipc_namespace.h file is used to store the prototypes of the\nfunctions in namespace.c and the stubs for NAMESPACES\u003dn case.  This is done\nso, because the stub for copy_ipc_namespace requires the knowledge of the\nCLONE_NEWIPC flag, which is in sched.h.  But the linux/ipc.h file itself in\nincluded into many many .c files via the sys.h-\u003esem.h sequence so adding the\nsched.h into it will make all these .c depend on sched.h which is not that\ngood.  On the other hand the knowledge about the namespaces stuff is required\nin 4 .c files only.\n\nBesides, this patch compiles out some auxiliary functions from ipc/sem.c,\nmsg.c and shm.c files.  It turned out that moving these functions into\nnamespaces.c is not that easy because they use many other calls and macros\nfrom the original file.  Moving them would make this patch complicated.  On\nthe other hand all these functions can be consolidated, so I will send a\nseparate patch doing this a bit later.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nCc: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nCc: \"Eric W.
