This mapping will borrow\nfunctionality from the huge page shm code to create a file on the kernel\ninternal mount and use it to approximate an anonymous mapping. The\nMAP_HUGETLB flag is a modifier to MAP_ANONYMOUS and will not work without\nboth flags being preset.\n\nA new flag is necessary because there is no other way to hook into huge\npages without creating a file on a hugetlbfs mount which wouldn\u0027t be\nMAP_ANONYMOUS.\n\nTo userspace, this mapping will behave just like an anonymous mapping\nbecause the file is not accessible outside of the kernel.\n\nThis patchset is meant to simplify the programming model. Presently there\nis a large chunk of boiler platecode, contained in libhugetlbfs, required\nto create private, hugepage backed mappings. This patch set would allow\nuse of hugepages without linking to libhugetlbfs or having hugetblfs\nmounted.\n\nUnification of the VM code would provide these same benefits, but it has\nbeen resisted each time that it has been suggested for several reasons: it\nwould break PAGE_SIZE assumptions across the kernel, it makes page-table\nabstractions really expensive, and it does not provide any benefit on\narchitectures that do not support huge pages, incurring fast path\npenalties without providing any benefit on these architectures.\n\nThis patch:\n\nThere are two means of creating mappings backed by huge pages:\n\n 1. mmap() a file created on hugetlbfs\n 2. Use shm which creates a file on an internal mount which essentially\n maps it MAP_SHARED\n\nThe internal mount is only used for shared mappings but there is very\nlittle that stops it being used for private mappings. This patch extends\nhugetlbfs_file_setup() to deal with the creation of files that will be\nmapped MAP_PRIVATE on the internal hugetlbfs mount. This extended API is\nused in a subsequent patch to implement the MAP_HUGETLB mmap() flag.\n\nSigned-off-by: Eric Munson \u003cebmunson@us.ibm.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b87221de6a4934eda856475a0065688d12973a04", "tree": "6bcf0628e106c4833538f4c23d710fbbe3d7609a", "parents": [ "0d54b217a247f39605361f867fefbb9e099a5432" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Sep 21 17:01:09 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:24 2009 -0700" }, "message": "const: mark remaining super_operations const\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2195d2818c37bdf263865f1e9effccdd9fc5f9d4", "tree": "3b74a195c2b69d8390c67c7cd46139df0bdd69ec", "parents": [ "69def9f05dfce3281bb06599057e6b8097385d39" ], "author": { "name": "Hugh Dickins", "email": "hugh.dickins@tiscali.co.uk", "time": "Sat Sep 12 12:21:27 2009 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Sep 14 17:45:31 2009 -0700" }, "message": "fix undefined reference to user_shm_unlock\n\nMy 353d5c30c666580347515da609dd74a2b8e9b828 \"mm: fix hugetlb bug due to\nuser_shm_unlock call\" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both\n2.6.31 and 2.6.30.6: \"undefined reference to `user_shm_unlock\u0027\".\n\ngcc didn\u0027t understand my comment! so couldn\u0027t figure out to optimize\naway user_shm_unlock() from the error path in the hugetlb-less case, as\nit does elsewhere.

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.

This solves two problems:\n\n (1) In SYSV SHM where nattch for a segment does not reflect the number of\n shmat\u0027s (and forks) done.\n\n (2) In mmap() where the VMA\u0027s vm_mm is set to point to the parent mm by an\n exec\u0027ing process when VM_EXECUTABLE is specified, regardless of the fact\n that a VMA might be shared and already have its vm_mm assigned to another\n process or a dead process.\n\nA new struct (vm_region) is introduced to track a mapped region and to remember\nthe circumstances under which it may be shared and the vm_list_struct structure\nis discarded as it\u0027s no longer required.\n\nThis patch makes the following additional changes:\n\n (1) Regions are now allocated with alloc_pages() rather than kmalloc() and\n with no recourse to __GFP_COMP, so the pages are not composite. Instead,\n each page has a reference on it held by the region. Anything else that is\n interested in such a page will have to get a reference on it to retain it.\n When the pages are released due to unmapping, each page is passed to\n put_page() and will be freed when the page usage count reaches zero.\n\n (2) Excess pages are trimmed after an allocation as the allocation must be\n made as a power-of-2 quantity of pages.\n\n (3) VMAs are added to the parent MM\u0027s R/B tree and mmap lists. As an MM may\n end up with overlapping VMAs within the tree, the VMA struct address is\n appended to the sort key.\n\n (4) Non-anonymous VMAs are now added to the backing inode\u0027s prio list.\n\n (5) Holes may be punched in anonymous VMAs with munmap(), releasing parts of\n the backing region. The VMA and region structs will be split if\n necessary.\n\n (6) sys_shmdt() only releases one attachment to a SYSV IPC shared memory\n segment instead of all the attachments at that addresss. Multiple\n shmat()\u0027s return the same address under NOMMU-mode instead of different\n virtual addresses as under MMU-mode.\n\n (7) Core dumping for ELF-FDPIC requires fewer exceptions for NOMMU-mode.\n\n (8) /proc/maps is now the global list of mapped regions, and may list bits\n that aren\u0027t actually mapped anywhere.\n\n (9) /proc/meminfo gains a line (tagged \"MmapCopy\") that indicates the amount\n of RAM currently allocated by mmap to hold mappable regions that can\u0027t be\n mapped directly. These are copies of the backing device or file if not\n anonymous.\n\nThese changes make NOMMU mode more similar to MMU mode. The downside is that\nNOMMU mode requires some extra memory to track things over NOMMU without this\npatch (VMAs are no longer shared, and there are now region structs).\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nTested-by: Mike Frysinger \u003cvapier.adi@gmail.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "4c2c3b4aaf3c10a636490438e9648a314ce414f9", "tree": "2e9b852fb178d8cb2982829d5a01711575d6d3a5", "parents": [ "e953ac2195659940d0d042f7ac962700a6a0f0e3" ], "author": { "name": "akpm@linux-foundation.org", "email": "akpm@linux-foundation.org", "time": "Tue Jan 06 14:42:51 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:59:29 2009 -0800" }, "message": "ipc/ipc_sysctl.c: move the definition of ipc_auto_callback()\n\nproc_ipcauto_dointvec_minmax() is the only user of ipc_auto_callback(),\nsince the former function is protected by CONFIG_PROC_FS, so should be the\nlatter one.\n\nJust move its definition down.\n\nSigned-off-by: WANG Cong \u003cwangcong@zeuux.org\u003e\nCc: Eric Biederman \u003cebiederm@xmision.com\u003e\nCc: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e953ac2195659940d0d042f7ac962700a6a0f0e3", "tree": "68eba3fff785161166b144b1bcf57858976cc9a4", "parents": [ "e8148f7588064e45080bf1120883380a2efe5c9b" ], "author": { "name": "Denis V.

With these patches, msgmni has a registered notification\nroutine that recomputes msgmni value upon memory add/remove or ipc\nnamespace creation/ removal.\n\nWhen msgmni is changed from user space (i.e. value written to the proc\nfile), that notification routine is unregistered, and the way to make it\nregistered back is to write a negative value into the proc file. This is\nthe \"magical positive-versus-negative number trick\".\n\nTo fix this, a new proc file is introduced: /proc/sys/kernel/auto_msgmni.\nThis file acts as ON/OFF for msgmni automatic recomputing.\n\nWith this patch, the process is the following:\n1) kernel boots in \"automatic recomputing mode\"\n /proc/sys/kernel/msgmni contains the value that has been computed (depends\n on lowmem)\n /proc/sys/kernel/automatic_msgmni contains \"1\"\n\n2) echo \u003cval\u003e \u003e /proc/sys/kernel/msgmni\n . sets msg_ctlmni to \u003cval\u003e\n . de-activates automatic recomputing (i.e. if, say, some memory is added\n msgmni won\u0027t be recomputed anymore)\n . /proc/sys/kernel/automatic_msgmni now contains \"0\"\n\n3) echo \"0\" \u003e /proc/sys/kernel/automatic_msgmni\n . de-activates msgmni automatic recomputing\n this has the same effect as 2) except that msg_ctlmni\u0027s value stays\n blocked at its current value)\n\n3) echo \"1\" \u003e /proc/sys/kernel/automatic_msgmni\n . recomputes msgmni\u0027s value based on the current available memory size\n and number of ipc namespaces\n . re-activates automatic recomputing for
