This happens if the process forks meanwhile, and the parent\nwrites to that page. As a result, the page is orphaned: in case of\nget_user_pages, the application will never see any data hardware DMA\u0027s into\nthis page after the COW. In case of mlock\u0027d memory, the parent is not getting\nthe realtime/security benefits of mlock.\n\nIn particular, this affects the Infiniband modules which do DMA from and into\nuser pages all the time.\n\nThis patch adds madvise options to control whether memory range is inherited\nacross fork.

Current\nimplementation supports only shmfs/tmpfs and other filesystems return\n-ENOSYS.\n\n\"Some app allocates large tmpfs files, then when some task quits and some\nclient disconnect, some memory can be released. However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3821af2fe13700cab6fd67367128fa180e43f8b8", "tree": "a70f63c24bd7d2ac8b25e3e4ee0ef6a50847aa67", "parents": [ "c865e5d99e25a171e8262fc0f7ba608568633c64" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@osdl.org", "time": "Wed Dec 21 19:30:53 2005 -0800" }, "committer": { "name": "David S.

It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c. (previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners. There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h | 16\n include/asm-x86_64/spinlock_types.h | 16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what.

I did not try to build\n non-SMP kernels. That should be trivial to fix up later if necessary.\n\n I converted bit ops atomic_hash lock to raw_spinlock_t. Doing so avoids\n some ugly nesting of linux/*.h and asm/*.h files. Those particular locks\n are well tested and contained entirely inside arch specific code. I do NOT\n expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n need to unravel this hairball between spinlocks, atomic ops, and bit ops\n that exist only because parisc has exactly one atomic instruction: LDCW\n (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n ia64 fix\n\nSigned-off-by: Ingo

This waiter wakes up and after a few instructions it\nattempts to acquire the cv internal lock, but that lock is still held by\nthe thread calling pthread_cond_signal. So it goes to sleep and eventually\nthe signalling thread is scheduled in, unlocks the internal lock and wakes\nthe waiter again.\n\nNow, before 2003-09-21 NPTL was using FUTEX_REQUEUE in pthread_cond_signal\nto avoid this performance issue, but it was removed when locks were\nredesigned to the 3 state scheme (unlocked, locked uncontended, locked\ncontended).\n\nFollowing scenario shows why simply using FUTEX_REQUEUE in\npthread_cond_signal together with using lll_mutex_unlock_force in place of\nlll_mutex_unlock is not enough and probably why it has been disabled at\nthat time:\n\nThe number is value in cv-\u003e__data.__lock.\n thr1 thr2 thr3\n0 pthread_cond_wait\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n0 lll_futex_wait (\u0026cv-\u003e__data.__futex, futexval)\n0 pthread_cond_signal\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n1 pthread_cond_signal\n2 lll_mutex_lock (cv-\u003e__data.__lock)\n2 lll_futex_wait (\u0026cv-\u003e__data.__lock, 2)\n2 lll_futex_requeue (\u0026cv-\u003e__data.__futex, 0, 1, \u0026cv-\u003e__data.__lock)\n # FUTEX_REQUEUE, not FUTEX_CMP_REQUEUE\n2 lll_mutex_unlock_force (cv-\u003e__data.__lock)\n0 cv-\u003e__data.__lock \u003d 0\n0 lll_futex_wake (\u0026cv-\u003e__data.__lock, 1)\n1 lll_mutex_lock (cv-\u003e__data.__lock)\n0 lll_mutex_unlock (cv-\u003e__data.__lock)\n # Here, lll_mutex_unlock doesn\u0027t know there are threads waiting\n # on the internal cv\u0027s lock\n\nNow, I believe it is possible to use FUTEX_REQUEUE in pthread_cond_signal,\nbut it will cost us not one, but 2 extra syscalls and, what\u0027s worse, one of\nthese extra syscalls will be done for every single waiting loop in\npthread_cond_*wait.\n\nWe would need to use lll_mutex_unlock_force in pthread_cond_signal after\nrequeue and lll_mutex_cond_lock in pthread_cond_*wait after lll_futex_wait.\n\nAnother alternative is to do the unlocking pthread_cond_signal needs to do\n(the lock can\u0027t be unlocked before lll_futex_wake, as that is racy) in the\nkernel.\n\nI have implemented both variants, futex-requeue-glibc.patch is the first\none and futex-wake_op{,-glibc}.patch is the unlocking inside of the kernel.\n The kernel interface allows userland to specify how exactly an unlocking\noperation should look like (some atomic arithmetic operation with optional\nconstant argument and comparison of the previous futex value with another\nconstant).\n\nIt has been implemented just for ppc*, x86_64 and i?86, for other\narchitectures I\u0027m including just a stub header which can be used as a\nstarting point by maintainers to write support for their arches and ATM\nwill just return -ENOSYS for FUTEX_WAKE_OP. The requeue patch has been\n(lightly) tested just on x86_64, the wake_op patch on ppc64 kernel running\n32-bit and 64-bit NPTL and x86_64 kernel running 32-bit and 64-bit NPTL.\n\nWith the following benchmark on UP x86-64 I get:\n\nfor i in nptl-orig nptl-requeue nptl-wake_op; do echo time elf/ld.so --library-path .:$i /tmp/bench; \\\nfor j in 1 2; do echo ( time elf/ld.so --library-path .:$i /tmp/bench ) 2\u003e\u00261; done; done\ntime elf/ld.so --library-path .:nptl-orig /tmp/bench\nreal 0m0.655s user 0m0.253s sys 0m0.403s\nreal 0m0.657s user 0m0.269s sys 0m0.388s\ntime elf/ld.so --library-path .:nptl-requeue /tmp/bench\nreal 0m0.496s user 0m0.225s sys 0m0.271s\nreal 0m0.531s user 0m0.242s sys 0m0.288s\ntime elf/ld.so --library-path .:nptl-wake_op /tmp/bench\nreal 0m0.380s user 0m0.176s sys 0m0.204s\nreal 0m0.382s user 0m0.175s sys 0m0.207s\n\nThe benchmark is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00001.txt\nOlder futex-requeue-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00002.txt\nOlder futex-wake_op-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00003.txt\nWill post a new version (just x86-64 fixes so that the patch\napplies against pthread_cond_signal.S) to libc-hacker ml soon.\n\nAttached is the kernel FUTEX_WAKE_OP patch as well as a simple-minded\ntestcase that will not test the atomicity of the operation, but at least\ncheck if the threads that should have been woken up are woken up and\nwhether the arithmetic operation in the kernel gave the expected results.\n\nAcked-by: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jamie Lokier \u003cjamie@shareable.org\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Yoichi Yuasa \u003cyuasa@hh.iij4u.or.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9513e5e3f5a6b429da8a9fd4330f71f1e547c8e0", "tree": "7585e2271d2fc3393aa2368cd7dad85d7552cd97", "parents": [ "c563077e526d130b8c9aab4e75116551eb5fdc2d" ], "author": { "name": "Heiko Carstens", "email": "heiko.carstens@de.ibm.com", "time": "Sat Sep 03 15:58:05 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:29 2005 -0700" }, "message": "[PATCH] s390: spinlock corner case\n\nOn s390 the lock value used for spinlocks consists of the lower 32 bits of the\nPSW that holds the lock.
