But by\ngrabbing the next event, the iter-\u003eent_size is set to the next event\ninstead of the current one. As the stacktrace event is the last event,\nthis makes the ent_size zero and causes nothing to be printed for\nthe stack trace. The dynamic stacktrace uses the ent_size to determine\nhow much of the stack can be printed.

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.

(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" }, { "commit": "b435092f70ec5ebbfb6d075d5bf3c631b49a51de", "tree": "c9cfd15c405dd218003fd84585196b5bffcc9bbd", "parents": [ "592fe8980688e7cba46897685d014c7fb3018a67" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 18 12:08:23 2012 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Apr 18 14:00:56 2012 +0200" }, "message": "tick: Fix oneshot broadcast setup really\n\nSven Joachim reported, that suspend/resume on rc3 trips over a NULL\npointer dereference.

(\"panic: don\u0027t print redundant backtraces on oops\")\ncauses a regression where no stack trace will be printed at all for the\ncase where kernel code calls panic() directly while not processing an\noops, and of course there are 100\u0027s of instances of this type of call.\n\nThe original commit executed the check (!oops_in_progress), but this will\nalways be false because just before the dump_stack() there is a call to\nbust_spinlocks(1), which does the following:\n\n void __attribute__((weak)) bust_spinlocks(int yes)\n {\n\tif (yes) {\n\t\t++oops_in_progress;\n\nThe proper way to resolve the problem that original commit tried to\nsolve is to avoid printing a stack dump from panic() when the either of\nthe following conditions is true:\n\n 1) TAINT_DIE has been set (this is done by oops_end())\n This indicates and oops has already been printed.\n 2) oops_in_progress \u003e 1\n This guards against the rare case where panic() is invoked\n a second time, or in between
