      "message": "irq: irqdomain: Add API to find free irq range\n\nWhen registering irq chip drivers, one common requirement is to\nspecify the irq_domain irq_base and nr_irq. These fields represent\nthe system wide logical interrupt range the domain occupies.\nFor systems with only one interrupt controller, it\u0027s trivial to\nknow these values. But for systems with several irq chip drivers,\nit becomes painful to keep track of interrupt ranges in platform\ndefines. These create needless compile time dependencies, of\nwhich the Device Tree aims to solve.\n\nirq_alloc_desc() can search for a free irq, but is very\ninefficient for determining the availability of large ranges.\nAdditionally, some irq chip drivers allocate irq descriptors\nlazily. For example, portions of the Device Tree may not be parsed\nuntil a particular bus is probed. But of_irq_init() is intended to\nbe run at init time, and this is a natural time to allocate irq\ndomains. Thus by the time we allocate our irq descriptors, we already\nneed to know a range of acceptable irqs to use for the domain.\n\nTo solve these problems, let\u0027s introduce\nirq_domain_find_free_range(), which will return to the caller the\nfirst available irq domain range not used already by the system.\nThis range can then be specified with irq_domain_add().\n\nChange-Id: I8b0f5d25b173c76b8fc5d4f46b3fe9c6bf5c3c8f\nSigned-off-by: Michael Bohan \u003cmbohan@codeaurora.org\u003e\n"

      "message": "irq: irqdomain: Add support for dynamic irq_desc allocations\n\nThe current irq_domain_add() design assumes the underlying\nirq_descs are valid when irq_domain_add() is called. It also\nassumes that every hwirq enlisted in the irq_domain is valid.\nOften, these assumptions are not correct.\n\nTypically, irq_domain_add() is called at board_init time, but\nsometimes interrupt chip drivers are not initialized until an\nunderlying bus is probed. When using SPARSE_IRQ, it\u0027s quite\nnatural to hold off allocating irq_descs until the board\ntopology specifies them as included.\n\nAnd in such device topologies, there\u0027s no guarantee that chip\ninterrupt numbers will be contiguous. For example, each hwirq may\nmap to a particular device, but that device may or may not be\npresent in the actual hardware configuration. In order to support\nthis, we need the concept of an irq_domain that supports holes\nin it.\n\nIn order to solve these problems, let\u0027s break the irq_domain\ncreation from the irq registration process. The irq_domain\ncreation can occur at init time and then have no dependencies. An\ninterrupt is not \u0027registered\u0027 with the domain until its resources\nhave already been allocated by the chip driver. For simple cases,\nan additional API is provided to register the entire\nlogical irq_domain range to provide feature parity with what\nalready exists.\n\nChange-Id: Ie3340d07ba8663196dc87d1185e3bb7fbed4be4d\nSigned-off-by: Michael Bohan \u003cmbohan@codeaurora.org\u003e\n"

      "message": "genirq: Add support for per-cpu dev_id interrupts\n\nThe ARM GIC interrupt controller offers per CPU interrupts (PPIs),\nwhich are usually used to connect local timers to each core. Each CPU\nhas its own private interface to the GIC, and only sees the PPIs that\nare directly connect to it.\n\nWhile these timers are separate devices and have a separate interrupt\nline to a core, they all use the same IRQ number.\n\nFor these devices, request_irq() is not the right API as it assumes\nthat an IRQ number is visible by a number of CPUs (through the\naffinity setting), but makes it very awkward to express that an IRQ\nnumber can be handled by all CPUs, and yet be a different interrupt\nline on each CPU, requiring a different dev_id cookie to be passed\nback to the handler.\n\nThe *_percpu_irq() functions is designed to overcome these\nlimitations, by providing a per-cpu dev_id vector:\n\nint request_percpu_irq(unsigned int irq, irq_handler_t handler,\n\t\t   const char *devname, void __percpu *percpu_dev_id);\nvoid free_percpu_irq(unsigned int, void __percpu *);\nint setup_percpu_irq(unsigned int irq, struct irqaction *new);\nvoid remove_percpu_irq(unsigned int irq, struct irqaction *act);\nvoid enable_percpu_irq(unsigned int irq);\nvoid disable_percpu_irq(unsigned int irq);\n\nThe API has a number of limitations:\n- no interrupt sharing\n- no threading\n- common handler across all the CPUs\n\nOnce the interrupt is requested using setup_percpu_irq() or\nrequest_percpu_irq(), it must be enabled by each core that wishes its\nlocal interrupt to be delivered.\n\nBased on an initial patch by Thomas Gleixner.\n\nChange-Id: I3e3d0f36e04added105753d30b2ef07e3d9d6a56\nSigned-off-by: Marc Zyngier \u003cmarc.zyngier@arm.com\u003e\nCc: linux-arm-kernel@lists.infradead.org\nLink: http://lkml.kernel.org/r/1316793788-14500-2-git-send-email-marc.zyngier@arm.com\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n[kumarrav@codeaurora.org: fixup manage.c merge conflict]\nSigned-off-by: Ravi Kumar \u003ckumarrav@codeaurora.org\u003e\n"

This is particularly important\nfor architectures adding device tree support because the current\nimplementation (excluding PowerPC and SPARC) cannot handle\ntranslation for more than a single interrupt controller.  irq_domain\nsupports device tree translation for any number of interrupt\ncontrollers.\n\nThis patch converts x86, Microblaze, ARM and MIPS to use irq_domain\nfor device tree irq translation.  x86 is untested beyond compiling it,\nirq_domain is enabled for MIPS and Microblaze, but the old behaviour is\npreserved until the core code is modified to actually register an\nirq_domain yet.  On ARM it works and is required for much of the new\nARM device tree board support.\n\nPowerPC has /not/ been converted to use this new infrastructure.  It\nis still missing some features before it can replace the virq\ninfrastructure already in powerpc (see documentation on\nirq_domain_map/unmap for details).  Followup patches will add the\nmissing pieces and migrate PowerPC to use irq_domain.\n\nSPARC has its own method of managing interrupts from the device tree\nand is unaffected by this change.\n\nChange-Id: Ia5fa674a97c85e2fc8e30275753b1494a97bd1d9\nAcked-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Grant Likely \u003cgrant.likely@secretlab.ca\u003e\nSigned-off-by: Sathish Ambley \u003csambley@codeaurora.org\u003e\n"

Note that check_irq_resend()\nonly does this for edge triggered interrupts.\n\nFor level triggered interrupts it is expected that the interrupt remains\nactive and doesn\u0027t need this PENDING flag assistance from software for\nre-triggering it.\n\nHowever, handle_fasteoi_irq flow handler sets the PENDING flag even for\na disabled level interrupt. This causes an adverse effect if that level\ninterrupt is marked wakeup. The suspend code sees the pending flag on a\nwakeup interrupt and aborts suspend whereas check_irq_resend does not reset\nit to 0 (as it is a level interrupt). The end result is that the PENDING\nflag on this level triggered wakeup interrupt never clears and the system\n keeps aborting suspend.\n\nFix this by setting IRQS_PENDING flag only for edge interrupts in the\nhandle_fasteoi_irq.\n\nCRs-Fixed: 314344\nChange-Id: I775d40f434f9309fd9672bae372b0f0fb5b91627\nSigned-off-by: Abhijeet Dharmapurikar \u003cadharmap@codeaurora.org\u003e\n"

When one or more ftrace_ops are registered,\nall the records that represent the functions that the ftrace_ops will\ntrace have a ref count incremented. If this ref count is not zero,\nwhen the code modification runs, that function will be enabled for tracing.\nIf the ref count is zero, that function will be disabled from tracing.\n\nTo make sure the accounting was working, FTRACE_WARN_ON()s were added\nto updating of the ref counts.\n\nIf the ref count hits its max (\u003e 2^30 ftrace_ops added), or if\nthe ref count goes below zero, a FTRACE_WARN_ON() is triggered which\ndisables all modification of code.\n\nSince it is common for ftrace_ops to trace all functions in the kernel,\ninstead of creating \u003e 20,000 hash items for the ftrace_ops, the hash\ncount is just set to zero, and it represents that the ftrace_ops is\nto trace all functions. This is where the issues arrise.\n\nIf you enable function tracing to trace all functions, and then add\na module, the modules function records do not get the ref count updated.\nWhen the function tracer is disabled, all function records ref counts\nare subtracted. Since the modules never had their ref counts incremented,\nthey go below zero and the FTRACE_WARN_ON() is triggered.\n\nThe solution to this is rather simple. When modules are loaded, and\ntheir functions are added to the the ftrace pool, look to see if any\nftrace_ops are registered that trace all functions. And for those,\nupdate the ref count for the module function records.\n\nReported-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n\n"

Just build it with \"gcc -o test test.c -lpthread -lrt\" or\n  similar.\n\n  Run it several times, and you will see cases where the main thread\n  will measure a process clock difference before and after the nanosleep\n  which is smaller than the cpu-burner thread\u0027s individual thread clock\n  difference.  This doesn\u0027t make any sense since the cpu-burner thread\n  is part of the top-level process\u0027s thread group.\n\n  I\u0027ve reproduced this on both x86-64 and sparc64 (using both 32-bit and\n  64-bit binaries).\n\n  For example:\n\n  [davem@boricha build-x86_64-linux]$ ./test\n  process: before(0.001221967) after(0.498624371) diff(497402404)\n  thread:  before(0.000081692) after(0.498316431) diff(498234739)\n  self:    before(0.001223521) after(0.001240219) diff(16698)\n  [davem@boricha build-x86_64-linux]$\n\n  The diff of \u0027process\u0027 should always be \u003e\u003d the diff of \u0027thread\u0027.\n\n  I make sure to wrap the \u0027thread\u0027 clock measurements the most tightly\n  around the nanosleep() call, and that the \u0027process\u0027 clock measurements\n  are the outer-most ones.\n\n  ---\n  #include \u003cunistd.h\u003e\n  #include \u003cstdio.h\u003e\n  #include \u003cstdlib.h\u003e\n  #include \u003ctime.h\u003e\n  #include \u003cfcntl.h\u003e\n  #include \u003cstring.h\u003e\n  #include \u003cerrno.h\u003e\n  #include \u003cpthread.h\u003e\n\n  static pthread_barrier_t barrier;\n\n  static void *chew_cpu(void *arg)\n  {\n\t  pthread_barrier_wait(\u0026barrier);\n\t  while (1)\n\t\t  __asm__ __volatile__(\"\" : : : \"memory\");\n\t  return NULL;\n  }\n\n  int main(void)\n  {\n\t  clockid_t process_clock, my_thread_clock, th_clock;\n\t  struct timespec process_before, process_after;\n\t  struct timespec me_before, me_after;\n\t  struct timespec th_before, th_after;\n\t  struct timespec sleeptime;\n\t  unsigned long diff;\n\t  pthread_t th;\n\t  int err;\n\n\t  err \u003d clock_getcpuclockid(0, \u0026process_clock);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d pthread_getcpuclockid(pthread_self(), \u0026my_thread_clock);\n\t  if (err)\n\t\t  return 1;\n\n\t  pthread_barrier_init(\u0026barrier, NULL, 2);\n\t  err \u003d pthread_create(\u0026th, NULL, chew_cpu, NULL);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d pthread_getcpuclockid(th, \u0026th_clock);\n\t  if (err)\n\t\t  return 1;\n\n\t  pthread_barrier_wait(\u0026barrier);\n\n\t  err \u003d clock_gettime(process_clock, \u0026process_before);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d clock_gettime(my_thread_clock, \u0026me_before);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d clock_gettime(th_clock, \u0026th_before);\n\t  if (err)\n\t\t  return 1;\n\n\t  sleeptime.tv_sec \u003d 0;\n\t  sleeptime.tv_nsec \u003d 500000000;\n\t  nanosleep(\u0026sleeptime, NULL);\n\n\t  err \u003d clock_gettime(th_clock, \u0026th_after);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d clock_gettime(my_thread_clock, \u0026me_after);\n\t  if (err)\n\t\t  return 1;\n\n\t  err \u003d clock_gettime(process_clock, \u0026process_after);\n\t  if (err)\n\t\t  return 1;\n\n\t  diff \u003d process_after.tv_nsec - process_before.tv_nsec;\n\t  printf(\"process: before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\\n\",\n\t\t process_before.tv_sec, process_before.tv_nsec,\n\t\t process_after.tv_sec, process_after.tv_nsec, diff);\n\t  diff \u003d th_after.tv_nsec - th_before.tv_nsec;\n\t  printf(\"thread:  before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\\n\",\n\t\t th_before.tv_sec, th_before.tv_nsec,\n\t\t th_after.tv_sec, th_after.tv_nsec, diff);\n\t  diff \u003d me_after.tv_nsec - me_before.tv_nsec;\n\t  printf(\"self:    before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\\n\",\n\t\t me_before.tv_sec, me_before.tv_nsec,\n\t\t me_after.tv_sec, me_after.tv_nsec, diff);\n\n\t  return 0;\n  }\n\nThis is due to us using p-\u003ese.sum_exec_runtime in\nthread_group_cputime() where we iterate the thread group and sum all\ndata. This does not take time since the last schedule operation (tick\nor otherwise) into account. We can cure this by using\ntask_sched_runtime() at the cost of having to take locks.\n\nThis also means we can (and must) do away with\nthread_group_sched_runtime() since the modified thread_group_cputime()\nis now more accurate and would deadlock when called from\nthread_group_sched_runtime().\n\nAside of that it makes the function safe on 32 bit systems. The old\ncode added t-\u003ese.sum_exec_runtime unprotected. sum_exec_runtime is a\n64bit value and could be changed on another cpu at the same time.\n\nReported-by: David Miller \u003cdavem@davemloft.net\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/1314874459.7945.22.camel@twins\nTested-by: David Miller \u003cdavem@davemloft.net\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

Lower priority tasks\nwill still have to wait on higher priority tasks, but the system should\nstill balance out because there is always the possibility that if there\nare both a high and low priority RT tasks on a given CPU that the high\npriority task could wakeup while the low priority task is running and\nforce it to search for a better runqueue.\n\nSigned-off-by: Shawn Bohrer \u003csbohrer@rgmadvisors.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nTested-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/1315837684-18733-1-git-send-email-sbohrer@rgmadvisors.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

These\ncalls should be made before entering the scheduler core.\n\nTo simplify this, separate the scheduler core code into\n__schedule(). __schedule() is directly called from the places which\nset PREEMPT_ACTIVE and from schedule().

This can lead to deadlock (The order in which\nworks are queued can be different on different cpu\u0027s. Some cpu\u0027s\nwill be running the first rendezvous handler and others will be running\nthe second rendezvous handler. Each set waiting for the other set to join\nfor the system wide rendezvous, leading to a deadlock).\n\nMTRR rendezvous sequence is not implemented using stop_machine() as this\ngets called both from the process context aswell as the cpu online paths\n(where the cpu has not come online and the interrupts are disabled etc).\nstop_machine() works with only online cpus.\n\nFor now, take the stop_machine mutex in the MTRR rendezvous sequence that\ngets called from an online cpu (here we are in the process context\nand can potentially sleep while taking the mutex). And the MTRR rendezvous\nthat gets triggered during cpu online doesn\u0027t need to take this stop_machine\nlock (as the stop_machine() already ensures that there is no cpu hotplug\ngoing on in parallel by doing get_online_cpus())\n\n    TBD: Pursue a cleaner solution of extending the stop_machine()\n         infrastructure to handle the case where the calling cpu is\n         still not online and use this for MTRR rendezvous sequence.\n\nfixes: https://bugzilla.novell.com/show_bug.cgi?id\u003d672008\n\nReported-by: Vadim Kotelnikov \u003cvadimuzzz@inbox.ru\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nLink: http://lkml.kernel.org/r/20110623182056.807230326@sbsiddha-MOBL3.sc.intel.com\nSigned-off-by: H.

      "message": "futex: Fix regression with read only mappings\n\ncommit 9ea71503a8ed9184d2d0b8ccc4d269d05f7940ae upstream.\n\ncommit 7485d0d3758e8e6491a5c9468114e74dc050785d (futexes: Remove rw\nparameter from get_futex_key()) in 2.6.33 fixed two problems:  First, It\nprevented a loop when encountering a ZERO_PAGE. Second, it fixed RW\nMAP_PRIVATE futex operations by forcing the COW to occur by\nunconditionally performing a write access get_user_pages_fast() to get\nthe page.  The commit also introduced a user-mode regression in that it\nbroke futex operations on read-only memory maps.  For example, this\nbreaks workloads that have one or more reader processes doing a\nFUTEX_WAIT on a futex within a read only shared file mapping, and a\nwriter processes that has a writable mapping issuing the FUTEX_WAKE.\n\nThis fixes the regression for valid futex operations on RO mappings by\ntrying a RO get_user_pages_fast() when the RW get_user_pages_fast()\nfails. This change makes it necessary to also check for invalid use\ncases, such as anonymous RO mappings (which can never change) and the\nZERO_PAGE which the commit referenced above was written to address.\n\nThis patch does restore the original behavior with RO MAP_PRIVATE\nmappings, which have inherent user-mode usage problems and don\u0027t really\nmake sense.  With this patch performing a FUTEX_WAIT within a RO\nMAP_PRIVATE mapping will be successfully woken provided another process\nupdates the region of the underlying mapped file.  However, the mmap()\nman page states that for a MAP_PRIVATE mapping:\n\n  It is unspecified whether changes made to the file after\n  the mmap() call are visible in the mapped region.\n\nSo user-mode users attempting to use futex operations on RO MAP_PRIVATE\nmappings are depending on unspecified behavior.  Additionally a\nRO MAP_PRIVATE mapping could fail to wake up in the following case.\n\n  Thread-A: call futex(FUTEX_WAIT, memory-region-A).\n            get_futex_key() return inode based key.\n            sleep on the key\n  Thread-B: call mprotect(PROT_READ|PROT_WRITE, memory-region-A)\n  Thread-B: write memory-region-A.\n            COW happen. This process\u0027s memory-region-A become related\n            to new COWed private (ie PageAnon\u003d1) page.\n  Thread-B: call futex(FUETX_WAKE, memory-region-A).\n            get_futex_key() return mm based key.\n            IOW, we fail to wake up Thread-A.\n\nOnce again doing something like this is just silly and users who do\nsomething like this get what they deserve.\n\nWhile RO MAP_PRIVATE mappings are nonsensical, checking for a private\nmapping requires walking the vmas and was deemed too costly to avoid a\nuserspace hang.\n\nThis Patch is based on Peter Zijlstra\u0027s initial patch with modifications to\nonly allow RO mappings for futex operations that need VERIFY_READ access.\n\nReported-by: David Oliver \u003cdavid@rgmadvisors.com\u003e\nSigned-off-by: Shawn Bohrer \u003csbohrer@rgmadvisors.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Darren Hart \u003cdvhart@linux.intel.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: peterz@infradead.org\nCc: eric.dumazet@gmail.com\nCc: zvonler@rgmadvisors.com\nCc: hughd@google.com\nLink: http://lkml.kernel.org/r/1309450892-30676-1-git-send-email-sbohrer@rgmadvisors.com\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

      "message": "mm/futex: fix futex writes on archs with SW tracking of dirty \u0026 young\n\ncommit 2efaca927f5cd7ecd0f1554b8f9b6a9a2c329c03 upstream.\n\nI haven\u0027t reproduced it myself but the fail scenario is that on such\nmachines (notably ARM and some embedded powerpc), if you manage to hit\nthat futex path on a writable page whose dirty bit has gone from the PTE,\nyou\u0027ll livelock inside the kernel from what I can tell.\n\nIt will go in a loop of trying the atomic access, failing, trying gup to\n\"fix it up\", getting succcess from gup, go back to the atomic access,\nfailing again because dirty wasn\u0027t fixed etc...\n\nSo I think you essentially hang in the kernel.\n\nThe scenario is probably rare\u0027ish because affected architecture are\nembedded and tend to not swap much (if at all) so we probably rarely hit\nthe case where dirty is missing or young is missing, but I think Shan has\na piece of SW that can reliably reproduce it using a shared writable\nmapping \u0026 fork or something like that.\n\nOn archs who use SW tracking of dirty \u0026 young, a page without dirty is\neffectively mapped read-only and a page without young unaccessible in the\nPTE.\n\nAdditionally, some architectures might lazily flush the TLB when relaxing\nwrite protection (by doing only a local flush), and expect a fault to\ninvalidate the stale entry if it\u0027s still present on another processor.\n\nThe futex code assumes that if the \"in_atomic()\" access -EFAULT\u0027s, it can\n\"fix it up\" by causing get_user_pages() which would then be equivalent to\ntaking the fault.\n\nHowever that isn\u0027t the case.  get_user_pages() will not call\nhandle_mm_fault() in the case where the PTE seems to have the right\npermissions, regardless of the dirty and young state.  It will eventually\nupdate those bits ...  in the struct page, but not in the PTE.\n\nAdditionally, it will not handle the lazy TLB flushing that can be\nrequired by some architectures in the fault case.\n\nBasically, gup is the wrong interface for the job.  The patch provides a\nmore appropriate one which boils down to just calling handle_mm_fault()\nsince what we are trying to do is simulate a real page fault.\n\nThe futex code currently attempts to write to user memory within a\npagefault disabled section, and if that fails, tries to fix it up using\nget_user_pages().\n\nThis doesn\u0027t work on archs where the dirty and young bits are maintained\nby software, since they will gate access permission in the TLB, and will\nnot be updated by gup().\n\nIn addition, there\u0027s an expectation on some archs that a spurious write\nfault triggers a local TLB flush, and that is missing from the picture as\nwell.\n\nI decided that adding those \"features\" to gup() would be too much for this\nalready too complex function, and instead added a new simpler\nfixup_user_fault() which is essentially a wrapper around handle_mm_fault()\nwhich the futex code can call.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: fix some nits Darren saw, fiddle comment layout]\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nReported-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nTested-by: Shan Hai \u003chaishan.bai@gmail.com\u003e\nCc: David Laight \u003cDavid.Laight@ACULAB.COM\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Darren Hart \u003cdarren.hart@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n"

      "message": "rcu: protect __rcu_read_unlock() against scheduler-using irq handlers\n\nThe addition of RCU read-side critical sections within runqueue and\npriority-inheritance lock critical sections introduced some deadlock\ncycles, for example, involving interrupts from __rcu_read_unlock()\nwhere the interrupt handlers call wake_up().  This situation can cause\nthe instance of __rcu_read_unlock() invoked from interrupt to do some\nof the processing that would otherwise have been carried out by the\ntask-level instance of __rcu_read_unlock().  When the interrupt-level\ninstance of __rcu_read_unlock() is called with a scheduler lock held\nfrom interrupt-entry/exit situations where in_irq() returns false,\ndeadlock can result.\n\nThis commit resolves these deadlocks by using negative values of\nthe per-task -\u003ercu_read_lock_nesting counter to indicate that an\ninstance of __rcu_read_unlock() is in flight, which in turn prevents\ninstances from interrupt handlers from doing any special processing.\nThis patch is inspired by Steven Rostedt\u0027s earlier patch that similarly\nmade __rcu_read_unlock() guard against interrupt-mediated recursion\n(see https://lkml.org/lkml/2011/7/15/326), but this commit refines\nSteven\u0027s approach to avoid the need for preemption disabling on the\n__rcu_read_unlock() fastpath and to also avoid the need for manipulating\na separate per-CPU variable.\n\nThis patch avoids need for preempt_disable() by instead using negative\nvalues of the per-task -\u003ercu_read_lock_nesting counter.  Note that nested\nrcu_read_lock()/rcu_read_unlock() pairs are still permitted, but they will\nnever see -\u003ercu_read_lock_nesting go to zero, and will therefore never\ninvoke rcu_read_unlock_special(), thus preventing them from seeing the\nRCU_READ_UNLOCK_BLOCKED bit should it be set in -\u003ercu_read_unlock_special.\nThis patch also adds a check for -\u003ercu_read_unlock_special being negative\nin rcu_check_callbacks(), thus preventing the RCU_READ_UNLOCK_NEED_QS\nbit from being set should a scheduling-clock interrupt occur while\n__rcu_read_unlock() is exiting from an outermost RCU read-side critical\nsection.\n\nOf course, __rcu_read_unlock() can be preempted during the time that\n-\u003ercu_read_lock_nesting is negative.  This could result in the setting\nof the RCU_READ_UNLOCK_BLOCKED bit after __rcu_read_unlock() checks it,\nand would also result it this task being queued on the corresponding\nrcu_node structure\u0027s blkd_tasks list.  Therefore, some later RCU read-side\ncritical section would enter rcu_read_unlock_special() to clean up --\nwhich could result in deadlock if that critical section happened to be in\nthe scheduler where the runqueue or priority-inheritance locks were held.\n\nThis situation is dealt with by making rcu_preempt_note_context_switch()\ncheck for negative -\u003ercu_read_lock_nesting, thus refraining from\nqueuing the task (and from setting RCU_READ_UNLOCK_BLOCKED) if we are\nalready exiting from the outermost RCU read-side critical section (in\nother words, we really are no longer actually in that RCU read-side\ncritical section).  In addition, rcu_preempt_note_context_switch()\ninvokes rcu_read_unlock_special() to carry out the cleanup in this case,\nwhich clears out the -\u003ercu_read_unlock_special bits and dequeues the task\n(if necessary), in turn avoiding needless delay of the current RCU grace\nperiod and needless RCU priority boosting.\n\nIt is still illegal to call rcu_read_unlock() while holding a scheduler\nlock if the prior RCU read-side critical section has ever had either\npreemption or irqs enabled.  However, the common use case is legal,\nnamely where then entire RCU read-side critical section executes with\nirqs disabled, for example, when the scheduler lock is held across the\nentire lifetime of the RCU read-side critical section.\n\nSigned-off-by: Paul E.

      "message": "rcu: Fix RCU_BOOST race handling current-\u003ercu_read_unlock_special\n\nThe RCU_BOOST commits for TREE_PREEMPT_RCU introduced an other-task\nwrite to a new RCU_READ_UNLOCK_BOOSTED bit in the task_struct structure\u0027s\n-\u003ercu_read_unlock_special field, but, as noted by Steven Rostedt, without\ncorrectly synchronizing all accesses to -\u003ercu_read_unlock_special.\nThis could result in bits in -\u003ercu_read_unlock_special being spuriously\nset and cleared due to conflicting accesses, which in turn could result\nin deadlocks between the rcu_node structure\u0027s -\u003elock and the scheduler\u0027s\nrq and pi locks.  These deadlocks would result from RCU incorrectly\nbelieving that the just-ended RCU read-side critical section had been\npreempted and/or boosted.  If that RCU read-side critical section was\nexecuted with either rq or pi locks held, RCU\u0027s ensuing (incorrect)\ncalls to the scheduler would cause the scheduler to attempt to once\nagain acquire the rq and pi locks, resulting in deadlock.  More complex\ndeadlock cycles are also possible, involving multiple rq and pi locks\nas well as locks from multiple rcu_node structures.\n\nThis commit fixes synchronization by creating -\u003ercu_boosted field in\ntask_struct that is accessed and modified only when holding the -\u003elock\nin the rcu_node structure on which the task is queued (on that rcu_node\nstructure\u0027s -\u003eblkd_tasks list).  This results in tasks accessing only\ntheir own current-\u003ercu_read_unlock_special fields, making unsynchronized\naccess once again legal, and keeping the rcu_read_unlock() fastpath free\nof atomic instructions and memory barriers.\n\nThe reason that the rcu_read_unlock() fastpath does not need to access\nthe new current-\u003ercu_boosted field is that this new field cannot\nbe non-zero unless the RCU_READ_UNLOCK_BLOCKED bit is set in the\ncurrent-\u003ercu_read_unlock_special field.  Therefore, rcu_read_unlock()\nneed only test current-\u003ercu_read_unlock_special: if that is zero, then\ncurrent-\u003ercu_boosted must also be zero.\n\nThis bug does not affect TINY_PREEMPT_RCU because this implementation\nof RCU accesses current-\u003ercu_read_unlock_special with irqs disabled,\nthus preventing races on the !SMP systems that TINY_PREEMPT_RCU runs on.\n\nMaybe-reported-by: Dave Jones \u003cdavej@redhat.com\u003e\nMaybe-reported-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nReported-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Paul E.
