ipc: change kern_ipc_perm.deleted type to bool

2014-01-28T05:02:39Z

struct kern_ipc_perm.deleted is meant to be used as a boolean toggle, and the changes introduced by this patch are just to make the case explicit.

userns: Convert ipc to use kuid and kgid where appropriate

2012-09-07T05:17:20Z

- Store the ipc owner and creator with a kuid - Store the ipc group and the crators group with a kgid. - Add error handling to ipc_update_perms, allowing it to fail if the uids and gids can not be converted to kuids or kgids. - Modify the proc files to display the ipc creator and owner in the user namespace of the opener of the proc file.

namespaces: move the IPC namespace under IPC_NS option

2008-02-08T17:22:23Z

Currently the IPC namespace management code is spread over the ipc/*.c files. I moved this code into ipc/namespace.c file which is compiled out when needed. The linux/ipc_namespace.h file is used to store the prototypes of the functions in namespace.c and the stubs for NAMESPACES=n case. This is done so, because the stub for copy_ipc_namespace requires the knowledge of the CLONE_NEWIPC flag, which is in sched.h. But the linux/ipc.h file itself in included into many many .c files via the sys.h->sem.h sequence so adding the sched.h into it will make all these .c depend on sched.h which is not that good. On the other hand the knowledge about the namespaces stuff is required in 4 .c files only. Besides, this patch compiles out some auxiliary functions from ipc/sem.c, msg.c and shm.c files. It turned out that moving these functions into namespaces.c is not that easy because they use many other calls and macros from the original file. Moving them would make this patch complicated. On the other hand all these functions can be consolidated, so I will send a separate patch doing this a bit later.

ipc: store ipcs into IDRs

2007-10-19T18:53:44Z

This patch introduces ipcs storage into IDRs. The main changes are: . This ipc_ids structure is changed: the entries array is changed into a root idr structure. . The grow_ary() routine is removed: it is not needed anymore when adding an ipc structure, since we are now using the IDR facility. . The ipc_rmid() routine interface is changed: . there is no need for this routine to return the pointer passed in as argument: it is now declared as a void . since the id is now part of the kern_ipc_perm structure, no need to have it as an argument to the routine Signed-off-by: Nadia Derbey Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

remove include/asm-*/ipc.h

2007-10-17T15:42:55Z

All asm/ipc.h files do only #include . This patch therefore removes all include/asm-*/ipc.h files and moves the contents of include/asm-generic/ipc.h to include/linux/ipc.h. Signed-off-by: Adrian Bunk Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

remove CONFIG_UTS_NS and CONFIG_IPC_NS

2007-07-16T16:05:47Z

CONFIG_UTS_NS and CONFIG_IPC_NS have very little value as they only deactivate the unshare of the uts and ipc namespaces and do not improve performance.
