      "message": "FUTEX: new PRIVATE futexes\n\n  Analysis of current linux futex code :\n  --------------------------------------\n\nA central hash table futex_queues[] holds all contexts (futex_q) of waiting\nthreads.\n\nEach futex_wait()/futex_wait() has to obtain a spinlock on a hash slot to\nperform lookups or insert/deletion of a futex_q.\n\nWhen a futex_wait() is done, calling thread has to :\n\n1) - Obtain a read lock on mmap_sem to be able to validate the user pointer\n     (calling find_vma()). This validation tells us if the futex uses\n     an inode based store (mapped file), or mm based store (anonymous mem)\n\n2) - compute a hash key\n\n3) - Atomic increment of reference counter on an inode or a mm_struct\n\n4) - lock part of futex_queues[] hash table\n\n5) - perform the test on value of futex.\n\t(rollback is value !\u003d expected_value, returns EWOULDBLOCK)\n\t(various loops if test triggers mm faults)\n\n6) queue the context into hash table, release the lock got in 4)\n\n7) - release the read_lock on mmap_sem\n\n   \u003cblock\u003e\n\n8) Eventually unqueue the context (but rarely, as this part  may be done\n   by the futex_wake())\n\nFutexes were designed to improve scalability but current implementation has\nvarious problems :\n\n- Central hashtable :\n\n  This means scalability problems if many processes/threads want to use\n  futexes at the same time.\n  This means NUMA unbalance because this hashtable is located on one node.\n\n- Using mmap_sem on every futex() syscall :\n\n  Even if mmap_sem is a rw_semaphore, up_read()/down_read() are doing atomic\n  ops on mmap_sem, dirtying cache line :\n    - lot of cache line ping pongs on SMP configurations.\n\n  mmap_sem is also extensively used by mm code (page faults, mmap()/munmap())\n  Highly threaded processes might suffer from mmap_sem contention.\n\n  mmap_sem is also used by oprofile code. Enabling oprofile hurts threaded\n  programs because of contention on the mmap_sem cache line.\n\n- Using an atomic_inc()/atomic_dec() on inode ref counter or mm ref counter:\n  It\u0027s also a cache line ping pong on SMP. It also increases mmap_sem hold time\n  because of cache misses.\n\nMost of these scalability problems come from the fact that futexes are in\none global namespace.  As we use a central hash table, we must make sure\nthey are all using the same reference (given by the mm subsystem).  We\nchose to force all futexes be \u0027shared\u0027.  This has a cost.\n\nBut fact is POSIX defined PRIVATE and SHARED, allowing clear separation,\nand optimal performance if carefuly implemented.  Time has come for linux\nto have better threading performance.\n\nThe goal is to permit new futex commands to avoid :\n - Taking the mmap_sem semaphore, conflicting with other subsystems.\n - Modifying a ref_count on mm or an inode, still conflicting with mm or fs.\n\nThis is possible because, for one process using PTHREAD_PROCESS_PRIVATE\nfutexes, we only need to distinguish futexes by their virtual address, no\nmatter the underlying mm storage is.\n\nIf glibc wants to exploit this new infrastructure, it should use new\n_PRIVATE futex subcommands for PTHREAD_PROCESS_PRIVATE futexes.  And be\nprepared to fallback on old subcommands for old kernels.  Using one global\nvariable with the FUTEX_PRIVATE_FLAG or 0 value should be OK.\n\nPTHREAD_PROCESS_SHARED futexes should still use the old subcommands.\n\nCompatibility with old applications is preserved, they still hit the\nscalability problems, but new applications can fly :)\n\nNote : the same SHARED futex (mapped on a file) can be used by old binaries\n*and* new binaries, because both binaries will use the old subcommands.\n\nNote : Vast majority of futexes should be using PROCESS_PRIVATE semantic,\nas this is the default semantic. Almost all applications should benefit\nof this changes (new kernel and updated libc)\n\nSome bench results on a Pentium M 1.6 GHz (SMP kernel on a UP machine)\n\n/* calling futex_wait(addr, value) with value !\u003d *addr */\n433 cycles per futex(FUTEX_WAIT) call (mixing 2 futexes)\n424 cycles per futex(FUTEX_WAIT) call (using one futex)\n334 cycles per futex(FUTEX_WAIT_PRIVATE) call (mixing 2 futexes)\n334 cycles per futex(FUTEX_WAIT_PRIVATE) call (using one futex)\nFor reference :\n187 cycles per getppid() call\n188 cycles per umask() call\n181 cycles per ni_syscall() call\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nPierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nCc: \"Ulrich Drepper\" \u003cdrepper@gmail.com\u003e\nCc: \"Nick Piggin\" \u003cnickpiggin@yahoo.com.au\u003e\nCc: \"Ingo Molnar\" \u003cmingo@elte.hu\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "Make futex_wait() use an hrtimer for timeout\n\nThis patch modifies futex_wait() to use an hrtimer + schedule() in place of\nschedule_timeout().\n\nschedule_timeout() is tick based, therefore the timeout granularity is the\ntick (1 ms, 4 ms or 10 ms depending on HZ).  By using a high resolution timer\nfor timeout wakeup, we can attain a much finer timeout granularity (in the\nmicrosecond range).  This parallels what is already done for futex_lock_pi().\n\nThe timeout passed to the syscall is no longer converted to jiffies and is\ntherefore passed to do_futex() and futex_wait() as an absolute ktime_t\ntherefore keeping nanosecond resolution.\n\nAlso this removes the need to pass the nanoseconds timeout part to\nfutex_lock_pi() in val2.\n\nIn futex_wait(), if there is no timeout then a regular schedule() is\nperformed.  Otherwise, an hrtimer is fired before schedule() is called.\n\n[akpm@linux-foundation.org: fix `make headers_check\u0027]\nSigned-off-by: Sebastien Dugue \u003csebastien.dugue@bull.net\u003e\nSigned-off-by: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

It turns out the problem is a reference count leak for\nthe security context in net/sunrpc/auth_gss/svcauth_gss.c.\n\nThe problem is that gss_write_init_verf() calls gss_svc_searchbyctx() which\ndoes a rsc_lookup() but never releases the reference to the context.  There is\nanother issue that rpc.svcgssd sets an \"end of time\" expiration for the\ncontext\n\nBy adding a cache_put() call in gss_svc_searchbyctx(), and setting an\nexpiration timeout in the downcall, cache_clean() does clean up the context\nand the module reference count now goes to zero after unmount.\n\nI also verified that if the context expires and then the client makes a new\nrequest, a new context is established.\n\nHere is the patch to fix the kernel, I will start a separate thread to discuss\nwhat expiration time should be set by rpc.svcgssd.\n\nAcked-by: \"J.

So it\nhangs forever if dwork doesn\u0027t do this, or cancel_rearming_delayed_work/\ncancel_delayed_work was already called.  It uses flush_workqueue() in a\nloop, so it can\u0027t be used if workqueue was freezed, and it is potentially\nlive- lockable on busy system if delay is small.\n\nWith this patch cancel_rearming_delayed_work() doesn\u0027t make any assumptions\nabout dwork, it can re-arm itself via queue_delayed_work(), or\nqueue_work(), or do nothing.\n\nAs a \"side effect\", cancel_work_sync() was changed to handle re-arming works\nas well.\n\nDisadvantages:\n\n\t- this patch adds wmb() to insert_work().\n\n\t- slowdowns the fast path (when del_timer() succeeds on entry) of\n\t  cancel_rearming_delayed_work(), because wait_on_work() is called\n\t  unconditionally. In that case, compared to the old version, we are\n\t  doing \"unneeded\" lock/unlock for each online CPU.\n\n\t  On the other hand, this means we don\u0027t need to use cancel_work_sync()\n\t  after cancel_rearming_delayed_work().\n\n\t- complicates the code (.text grows by 130 bytes).\n\n[akpm@linux-foundation.org: fix speling]\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Gautham Shenoy \u003cego@in.ibm.com\u003e\nAcked-by: Jarek Poplawski \u003cjarkao2@o2.pl\u003e\nCc: Srivatsa Vaddagiri \u003cvatsa@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "change kernel threads to ignore signals instead of blocking them\n\nCurrently kernel threads use sigprocmask(SIG_BLOCK) to protect against\nsignals.  This doesn\u0027t prevent the signal delivery, this only blocks\nsignal_wake_up().  Every \"killall -33 kthreadd\" means a \"struct siginfo\"\nleak.\n\nChange kthreadd_setup() to set all handlers to SIG_IGN instead of blocking\nthem (make a new helper ignore_signals() for that).  If the kernel thread\nneeds some signal, it should use allow_signal() anyway, and in that case it\nshould not use CLONE_SIGHAND.\n\nNote that we can\u0027t change daemonize() (should die!) in the same way,\nbecause it can be used along with CLONE_SIGHAND.  This means that\nallow_signal() still should unblock the signal to work correctly with\ndaemonize()ed threads.\n\nHowever, disallow_signal() doesn\u0027t block the signal any longer but ignores\nit.\n\nNOTE: with or without this patch the kernel threads are not protected from\nhandle_stop_signal(), this seems harmless, but not good.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: \"Eric W.

      "message": "workqueue: fix flush_workqueue() vs CPU_DEAD race\n\nMany thanks to Srivatsa Vaddagiri for the helpful discussion and for spotting\nthe bug in my previous attempt.\n\nwork-\u003efunc() (and thus flush_workqueue()) must not use workqueue_mutex,\nthis leads to deadlock when CPU_DEAD does kthread_stop(). However without\nthis mutex held we can\u0027t detect CPU_DEAD in progress, which can move pending\nworks to another CPU while the dead one is not on cpu_online_map.\n\nChange flush_workqueue() to use for_each_possible_cpu(). This means that\nflush_cpu_workqueue() may hit CPU which is already dead. However in that\ncase\n\n\t!list_empty(\u0026cwq-\u003eworklist) || cwq-\u003ecurrent_work !\u003d NULL\n\nmeans that CPU_DEAD in progress, it will do kthread_stop() + take_over_work()\nso we can proceed and insert a barrier. We hold cwq-\u003elock, so we are safe.\n\nAlso, add migrate_sequence incremented by take_over_work() under cwq-\u003elock.\nIf take_over_work() happened before we checked this CPU, we should see the\nnew value after spin_unlock().\n\nFurther possible changes:\n\n\tremove CPU_DEAD handling (along with take_over_work, migrate_sequence)\n\tfrom workqueue.c. CPU_DEAD just sets cwq-\u003eplease_exit_after_flush flag.\n\n\tCPU_UP_PREPARE-\u003ecreate_workqueue_thread() clears this flag, and creates\n\tthe new thread if cwq-\u003ethread \u003d\u003d NULL.\n\nThis way the workqueue/cpu-hotplug interaction is almost zero, workqueue_mutex\njust protects \"workqueues\" list, CPU_LOCK_ACQUIRE/CPU_LOCK_RELEASE go away.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Srivatsa Vaddagiri \u003cvatsa@in.ibm.com\u003e\nCc: \"Pallipadi, Venkatesh\" \u003cvenkatesh.pallipadi@intel.com\u003e\nCc: Gautham shenoy \u003cego@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This one is along the\nlines of the solution provided in kernel/workqueue.c\n\nInstead of having a global mechanism like lock_cpu_hotplug, we allow the\nsubsytems to define their own per-subsystem hot cpu mutexes.  These would be\ntaken(released) where ever we are currently calling\nlock_cpu_hotplug(unlock_cpu_hotplug).\n\nAlso, in the per-subsystem hotcpu callback function,we take this mutex before\nwe handle any pre-cpu-hotplug events and release it once we finish handling\nthe post-cpu-hotplug events.  A standard means for doing this has been\nprovided in [PATCH 2/4] and demonstrated in [PATCH 3/4].\n\nThe ordering of these per-subsystem mutexes might still prove to be a\nproblem, but hopefully lockdep should help us get out of that muddle.\n\nThe patch set to be applied against linux-2.6.19-rc5 is as follows:\n\n[PATCH 1/4] :\tExtend notifier_call_chain with an option to specify the\n\t\tnumber of notifications to be sent and also count the\n\t\tnumber of notifications actually sent.\n\n[PATCH 2/4] :\tDefine events CPU_LOCK_ACQUIRE and CPU_LOCK_RELEASE\n\t\tand send out notifications for these in _cpu_up and\n\t\t_cpu_down. This would help us standardise the acquire and\n\t\trelease of the subsystem locks in the hotcpu\n\t\tcallback functions of these subsystems.\n\n[PATCH 3/4] :\tEliminate lock_cpu_hotplug from kernel/sched.c.\n\n[PATCH 4/4] :\tIn workqueue_cpu_callback function, acquire(release) the\n\t\tworkqueue_mutex while handling\n\t\tCPU_LOCK_ACQUIRE(CPU_LOCK_RELEASE).\n\nIf the per-subsystem-locking approach survives the test of time, we can expect\na slow phasing out of lock_cpu_hotplug, which has not yet been eliminated in\nthese patches :)\n\nThis patch:\n\nProvide notifier_call_chain with an option to call only a specified number of\nnotifiers and also record the number of call to notifiers made.\n\nThe need for this enhancement was identified in the post entitled\n\"Slab - Eliminate lock_cpu_hotplug from slab\"\n(http://lkml.org/lkml/2006/10/28/92) by Ravikiran G Thirumalai and\nAndrew Morton.\n\nThis patch adds two additional parameters to notifier_call_chain API namely\n - int nr_to_calls : Number of notifier_functions to be called.\n \t\t     The don\u0027t care value is -1.\n\n - unsigned int *nr_calls : Records the total number of notifier_funtions\n\t\t\t    called by notifier_call_chain.

      "message": "implement flush_work()\n\nA basic problem with flush_scheduled_work() is that it blocks behind _all_\npresently-queued works, rather than just the work whcih the caller wants to\nflush.  If the caller holds some lock, and if one of the queued work happens\nto want that lock as well then accidental deadlocks can occur.\n\nOne example of this is the phy layer: it wants to flush work while holding\nrtnl_lock().  But if a linkwatch event happens to be queued, the phy code will\ndeadlock because the linkwatch callback function takes rtnl_lock.\n\nSo we implement a new function which will flush a *single* work - just the one\nwhich the caller wants to free up.  Thus we avoid the accidental deadlocks\nwhich can arise from unrelated subsystems\u0027 callbacks taking shared locks.\n\nflush_work() non-blockingly dequeues the work_struct which we want to kill,\nthen it waits for its handler to complete on all CPUs.\n\nAdd -\u003ecurrent_work to the \"struct cpu_workqueue_struct\", it points to\ncurrently running \"struct work_struct\". When flush_work(work) detects\n-\u003ecurrent_work \u003d\u003d work, it inserts a barrier at the _head_ of -\u003eworklist\n(and thus right _after_ that work) and waits for completition. This means\nthat the next work fired on that CPU will be this barrier, or another\nbarrier queued by concurrent flush_work(), so the caller of flush_work()\nwill be woken before any \"regular\" work has a chance to run.\n\nWhen wait_on_work() unlocks workqueue_mutex (or whatever we choose to protect\nagainst CPU hotplug), CPU may go away. But in that case take_over_work() will\nmove a barrier we queued to another CPU, it will be fired sometime, and\nwait_on_work() will be woken.\n\nActually, we are doing cleanup_workqueue_thread()-\u003ekthread_stop() before\ntake_over_work(), so cwq-\u003ethread should complete its -\u003eworklist (and thus\nthe barrier), because currently we don\u0027t check kthread_should_stop() in\nrun_workqueue(). But even if we did, everything should be ok.\n\n[akpm@osdl.org: cleanup]\n[akpm@osdl.org: add flush_work_keventd() wrapper]\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Such reservation is\ncompletely rubbish in the presence of cpuset because the reservation is not\nchecked against page availability for the current cpuset.  Application can\nstill potentially OOM\u0027ed by kernel with lack of free htlb page in cpuset\nthat the task is in.  Attempt to enforce strict accounting with cpuset is\nalmost impossible (or too ugly) because cpuset is too fluid that task or\nmemory node can be dynamically moved between cpusets.\n\nThe change of semantics for shared hugetlb mapping with cpuset is\nundesirable.  However, in order to preserve some of the semantics, we fall\nback to check against current free page availability as a best attempt and\nhopefully to minimize the impact of changing semantics that cpuset has on\nhugetlb.\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nCc: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
