This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations. I haven\u0027t found a regression in any non-micro benchmark so I\ndoubt it will be a problem.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n" }, { "commit": "3af54c9bd9e6f14f896aac1bb0e8405ae0bc7a44", "tree": "74eb7ea6396c3ad00fce944789071ded2e0b85e8", "parents": [ "504b701bb1655747575095543c083267418e02ac" ], "author": { "name": "Vasiliy Kulikov", "email": "segooon@gmail.com", "time": "Sat Oct 30 18:22:49 2010 +0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Oct 30 08:25:51 2010 -0700" }, "message": "ipc: shm: fix information leak to userland\n\nThe shmid_ds structure is copied to userland with shm_unused{,2,3}\nfields unitialized.

The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "45575f5a426c01ec68cd33d998267ba2f6278fac", "tree": "f34a857f471e5249bda3fca723e4b69ba6ce552c", "parents": [ "a90110c61073eab95d1986322693c2b9a8a6a5f6" ], "author": { "name": "Anton Blanchard", "email": "anton@samba.org", "time": "Mon Mar 22 17:47:59 2010 +1100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 22 09:57:19 2010 -0700" }, "message": "ppc64 sys_ipc breakage in 2.6.34-rc2\n\nI chased down a fail on ppc64 on 2.6.34-rc2 where an application that\nuses shared memory was getting a SEGV.\n\nCommit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 (\"Add generic sys_ipc\nwrapper\") changed the second argument from an unsigned long to an int.\nWhen we call shmget the system call wrappers for sys_ipc will sign\nextend second (ie the size) which truncates it.

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 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.
