      "message": "clockevents: Sanitize ticks to nsec conversion\n\ncommit 97b9410643475d6557d2517c2aff9fd2221141a9 upstream.\n\nMarc Kleine-Budde pointed out, that commit 77cc982 \"clocksource: use\nclockevents_config_and_register() where possible\" caused a regression\nfor some of the converted subarchs.\n\nThe reason is, that the clockevents core code converts the minimal\nhardware tick delta to a nanosecond value for core internal\nusage. This conversion is affected by integer math rounding loss, so\nthe backwards conversion to hardware ticks will likely result in a\nvalue which is less than the configured hardware limitation. The\naffected subarchs used their own workaround (SIGH!) which got lost in\nthe conversion.\n\nThe solution for the issue at hand is simple: adding evt-\u003emult - 1 to\nthe shifted value before the integer divison in the core conversion\nfunction takes care of it. But this only works for the case where for\nthe scaled math mult/shift pair \"mult \u003c\u003d 1 \u003c\u003c shift\" is true. For the\ncase where \"mult \u003e 1 \u003c\u003c shift\" we can apply the rounding add only for\nthe minimum delta value to make sure that the backward conversion is\nnot less than the given hardware limit. For the upper bound we need to\nomit the rounding add, because the backwards conversion is always\nlarger than the original latch value. That would violate the upper\nbound of the hardware device.\n\nThough looking closer at the details of that function reveals another\nbogosity: The upper bounds check is broken as well. Checking for a\nresulting \"clc\" value greater than KTIME_MAX after the conversion is\npointless. The conversion does:\n\n      u64 clc \u003d (latch \u003c\u003c evt-\u003eshift) / evt-\u003emult;\n\nSo there is no sanity check for (latch \u003c\u003c evt-\u003eshift) exceeding the\n64bit boundary. The latch argument is \"unsigned long\", so on a 64bit\narch the handed in argument could easily lead to an unnoticed shift\noverflow. With the above rounding fix applied the calculation before\nthe divison is:\n\n       u64 clc \u003d (latch \u003c\u003c evt-\u003eshift) + evt-\u003emult - 1;\n\nSo we need to make sure, that neither the shift nor the rounding add\nis overflowing the u64 boundary.\n\n[ukl: move assignment to rnd after eventually changing mult, fix build\n issue and correct comment with the right math]\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Russell King - ARM Linux \u003clinux@arm.linux.org.uk\u003e\nCc: Marc Kleine-Budde \u003cmkl@pengutronix.de\u003e\nCc: nicolas.ferre@atmel.com\nCc: Marc Pignat \u003cmarc.pignat@hevs.ch\u003e\nCc: john.stultz@linaro.org\nCc: kernel@pengutronix.de\nCc: Ronald Wahl \u003cronald.wahl@raritan.com\u003e\nCc: LAK \u003clinux-arm-kernel@lists.infradead.org\u003e\nCc: Ludovic Desroches \u003cludovic.desroches@atmel.com\u003e\nLink: http://lkml.kernel.org/r/1380052223-24139-1-git-send-email-u.kleine-koenig@pengutronix.de\nSigned-off-by: Uwe Kleine-König \u003cu.kleine-koenig@pengutronix.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n"

What happens is that the per cpu HPET timer\ngets shut down when the nonboot cpus are stopped. When the nonboot\ncpus are onlined again the HPET code sets up the MSI interrupt which\nfires before the clock event device is registered. The event handler\nis still set to hrtimer_interrupt, which then crashes the machine due\nto highres mode not being active.\n\nSee http://bugs.debian.org/cgi-bin/bugreport.cgi?bug\u003d700333\n\nThere is no real good way to avoid that in the HPET code. The HPET\ncode alrady has a mechanism to detect spurious interrupts when event\nhandler \u003d\u003d NULL for a similar reason.\n\nWe can handle that in the clockevent/tick layer and replace the\nprevious functional handler with a dummy handler like we do in\ntick_setup_new_device().\n\nThe original clockevents code did this in clockevents_exchange_device(),\nbut that got removed by commit 7c1e76897 (clockevents: prevent\nclockevent event_handler ending up handler_noop) which forgot to fix\nit up in tick_shutdown().

      "message": "tick: Ensure that the broadcast device is initialized\n\nSantosh found another trap when we avoid to initialize the broadcast\ndevice in the switch_to_oneshot code. The broadcast device might be\nstill in SHUTDOWN state when we actually need to use it. That\nobviously breaks, as set_next_event() is called on a shutdown\ndevice. This did not break on x86, but Suresh analyzed it:\n\nFrom the review, most likely on Sven\u0027s system we are force enabling\nthe hpet using the pci quirk\u0027s method very late. And in this case,\nhpet_clockevent (which will be global_clock_event) handler can be\nnull, specifically as this platform might not be using deeper c-states\nand using the reliable APIC timer.\n\nPrior to commit \u0027fa4da365bc7772c\u0027, that handler will be set to\n\u0027tick_handle_oneshot_broadcast\u0027 when we switch the broadcast timer to\noneshot mode, even though we don\u0027t use it. Post commit\n\u0027fa4da365bc7772c\u0027, we stopped switching the broadcast mode to oneshot\nas this is not really needed and his platform\u0027s global_clock_event\u0027s\nhandler will remain null. While on my SNB laptop, same is set to\n\u0027clockevents_handle_noop\u0027 because hpet gets enabled very early. (noop\nhandler on my platform set when the early enabled hpet timer gets\nreplaced by the lapic timer).\n\nBut the commit \u0027fa4da365bc7772c\u0027 tracked the broadcast timer mode in\nthe SW as oneshot, even though it didn\u0027t touch the HW timer. During\nresume however, tick_resume_broadcast() saw the SW broadcast mode as\noneshot and actually programmed the broadcast device also into oneshot\nmode. So this triggered the null pointer de-reference after the hpet\nwraps around and depending on what the hpet counter is set to. On the\nnormal platforms where hpet gets enabled early we should be seeing a\nspurious interrupt (in my SNB laptop I see one spurious interrupt\nafter around 5 minutes ;) which is 32-bit hpet counter wraparound\ntime), but that\u0027s a separate issue.\n\nEnforce the mode setting when trying to set an event.\n\nReported-and-tested-by: Santosh Shilimkar \u003csantosh.shilimkar@ti.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nCc: torvalds@linux-foundation.org\nCc: svenjoac@gmx.de\nCc: rjw@sisk.pl\nLink: http://lkml.kernel.org/r/alpine.LFD.2.02.1204181723350.2542@ionos\n\n"

      "message": "tick: Fix oneshot broadcast setup really\n\nSven Joachim reported, that suspend/resume on rc3 trips over a NULL\npointer dereference. Linus spotted the clockevent handler being NULL.\n\ncommit fa4da365b(clockevents: tTack broadcast device mode change in\ntick_broadcast_switch_to_oneshot()) tried to fix a problem with the\nbroadcast device setup, which was introduced in commit 77b0d60c5(\nclockevents: Leave the broadcast device in shutdown mode when not\nneeded).\n\nThe initial commit avoided to set up the broadcast device when no\nbroadcast request bits were set, but that left the broadcast device\ndisfunctional. In consequence deep idle states which need the\nbroadcast device were not woken up.\n\ncommit fa4da365b tried to fix that by initializing the state of the\nbroadcast facility, but that missed the fact, that nothing initializes\nthe event handler and some other state of the underlying clock event\ndevice.\n\nThe fix is to revert both commits and make only the mode setting of\nthe clock event device conditional on the state of active broadcast\nusers. \n\nThat initializes everything except the low level device mode, but this\nhappens when the broadcast functionality is invoked by deep idle.\n\nReported-and-tested-by: Sven Joachim \u003csvenjoac@gmx.de\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Rafael J.

      "message": "ntp: Fix leap-second hrtimer livelock\n\nSince commit 7dffa3c673fbcf835cd7be80bb4aec8ad3f51168 the ntp\nsubsystem has used an hrtimer for triggering the leapsecond\nadjustment. However, this can cause a potential livelock.\n\nThomas diagnosed this as the following pattern:\nCPU 0                                                    CPU 1\ndo_adjtimex()\n  spin_lock_irq(\u0026ntp_lock);\n    process_adjtimex_modes();\t\t\t\t timer_interrupt()\n      process_adj_status();                                do_timer()\n        ntp_start_leap_timer();                             write_lock(\u0026xtime_lock);\n          hrtimer_start();                                  update_wall_time();\n             hrtimer_reprogram();                            ntp_tick_length()\n               tick_program_event()                            spin_lock(\u0026ntp_lock);\n                 clockevents_program_event()\n\t\t   ktime_get()\n                     seq \u003d req_seqbegin(xtime_lock);\n\nThis patch tries to avoid the problem by reverting back to not using\nan hrtimer to inject leapseconds, and instead we handle the leapsecond\nprocessing in the second_overflow() function.\n\nThe downside to this change is that on systems that support highres\ntimers, the leap second processing will occur on a HZ tick boundary,\n(ie: ~1-10ms, depending on HZ)  after the leap second instead of\npossibly sooner (~34us in my tests w/ x86_64 lapic).\n\nThis patch applies on top of tip/timers/core.\n\nCC: Sasha Levin \u003clevinsasha928@gmail.com\u003e\nCC: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReported-by: Sasha Levin \u003clevinsasha928@gmail.com\u003e\nDiagnoised-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nTested-by: Sasha Levin \u003clevinsasha928@gmail.com\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n"

      "message": "nohz: Separate out irq exit and idle loop dyntick logic\n\nThe tick_nohz_stop_sched_tick() function, which tries to delay\nthe next timer tick as long as possible, can be called from two\nplaces:\n\n- From the idle loop to start the dytick idle mode\n- From interrupt exit if we have interrupted the dyntick\nidle mode, so that we reprogram the next tick event in\ncase the irq changed some internal state that requires this\naction.\n\nThere are only few minor differences between both that\nare handled by that function, driven by the ts-\u003einidle\ncpu variable and the inidle parameter. The whole guarantees\nthat we only update the dyntick mode on irq exit if we actually\ninterrupted the dyntick idle mode, and that we enter in RCU extended\nquiescent state from idle loop entry only.\n\nSplit this function into:\n\n- tick_nohz_idle_enter(), which sets ts-\u003einidle to 1, enters\ndynticks idle mode unconditionally if it can, and enters into RCU\nextended quiescent state.\n\n- tick_nohz_irq_exit() which only updates the dynticks idle mode\nwhen ts-\u003einidle is set (ie: if tick_nohz_idle_enter() has been called).\n\nTo maintain symmetry, tick_nohz_restart_sched_tick() has been renamed\ninto tick_nohz_idle_exit().\n\nThis simplifies the code and micro-optimize the irq exit path (no need\nfor local_irq_save there). This also prepares for the split between\ndynticks and rcu extended quiescent state logics. We\u0027ll need this split to\nfurther fix illegal uses of RCU in extended quiescent states in the idle\nloop.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Frysinger \u003cvapier@gentoo.org\u003e\nCc: Guan Xuetao \u003cgxt@mprc.pku.edu.cn\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nCc: Hans-Christian Egtvedt \u003chans-christian.egtvedt@atmel.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Paul E.

A more\nfine-grained detection of idleness is therefore required.\n\nThis commit presses the old dyntick-idle code into full-time service,\nso that rcu_idle_enter(), previously known as rcu_enter_nohz(), is\nalways invoked at the beginning of an idle loop iteration.  Similarly,\nrcu_idle_exit(), previously known as rcu_exit_nohz(), is always invoked\nat the end of an idle-loop iteration.  This allows the idle task to\nuse RCU everywhere except between consecutive rcu_idle_enter() and\nrcu_idle_exit() calls, in turn allowing architecture maintainers to\nspecify exactly where in the idle loop that RCU may be used.\n\nBecause some of the userspace upcall uses can result in what looks\nto RCU like half of an interrupt, it is not possible to expect that\nthe irq_enter() and irq_exit() hooks will give exact counts.  This\npatch therefore expands the -\u003edynticks_nesting counter to 64 bits\nand uses two separate bitfields to count process/idle transitions\nand interrupt entry/exit transitions.  It is presumed that userspace\nupcalls do not happen in the idle loop or from usermode execution\n(though usermode might do a system call that results in an upcall).\nThe counter is hard-reset on each process/idle transition, which\navoids the interrupt entry/exit error from accumulating.  Overflow\nis avoided by the 64-bitness of the -\u003edyntick_nesting counter.\n\nThis commit also adds warnings if a non-idle task asks RCU to enter\nidle state (and these checks will need some adjustment before applying\nFrederic\u0027s OS-jitter patches (http://lkml.org/lkml/2011/10/7/246).\nIn addition, validation of -\u003edynticks and -\u003edynticks_nesting is added.\n\nSigned-off-by: Paul E.

      "message": "nohz: Fix update_ts_time_stat idle accounting\n\nupdate_ts_time_stat currently updates idle time even if we are in\niowait loop at the moment. The only real users of the idle counter\n(via get_cpu_idle_time_us) are CPU governors and they expect to get\ncumulative time for both idle and iowait times.\nThe value (idle_sleeptime) is also printed to userspace by print_cpu\nbut it prints both idle and iowait times so the idle part is misleading.\n\nLet\u0027s clean this up and fix update_ts_time_stat to account both counters\nproperly and update consumers of idle to consider iowait time as well.\nIf we do this we might use get_cpu_{idle,iowait}_time_us from other\ncontexts as well and we will get expected values.\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Dave Jones \u003cdavej@redhat.com\u003e\nCc: Arnd Bergmann \u003carnd@arndb.de\u003e\nCc: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nLink: http://lkml.kernel.org/r/e9c909c221a8da402c4da07e4cd968c3218f8eb1.1314172057.git.mhocko@suse.cz\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n"
