This field can accidentally be left\ninitialized, which is why we currently memset buffers returned to\nuserland in rtc_read_time.\n\nThere is a case however where the field can return garbage from the\nstack though when using the RTC_ALM_READ ioctl on the rtc device. This\nioctl invokes rtc_read_alarm, which is careful to memset the rtc_wkalrm\nbuffer that is copied to userland, but it then uses a struct copy to\nassign to alarm-\u003etime given the return value from rtc_ktime_to_tm().\n\nrtc_ktime_to_tm() is implemented by calling rtc_time_to_tm using a\nderivative seconds counds from ktime, but rtc_time_to_tm does not assign\na value to -\u003etm_isdst. This results in garbage from rtc_ktime_to_tm()\u0027s\nframe ending up being copied out to userland as part of the returned\nrtc_wkalrm.\n\nFix this by initializing rtc_time-\u003etm_isdst to 0 in rtc_time_to_tm.\n\nSigned-off-by: Mike Waychison \u003cmikew@google.com\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n" }, { "commit": "6610e0893b8bc6f59b14fed7f089c5997f035f88", "tree": "b13f4f516fe8fd31a6f6fbb68dd0c520c4c19df7", "parents": [ "b007c389d3e09b823eccda1503390fa2a9adca0d" ], "author": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Thu Sep 23 15:07:34 2010 -0700" }, "committer": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Fri Dec 10 22:24:24 2010 -0800" }, "message": "RTC: Rework RTC code to use timerqueue for events\n\nThis patch reworks a large portion of the generic RTC code\nto in-effect virtualize the rtc interrupt code.\n\nThe current RTC interface is very much a raw hardware interface.\nVia the proc, /dev/, or sysfs interfaces, applciations can set\nthe hardware to trigger interrupts in one of three modes:\n\nAIE: Alarm interrupt\nUIE: Update interrupt (ie: once per second)\nPIE: Periodic interrupt (sub-second irqs)\n\nThe problem with this interface is that it limits the RTC hardware\nso it can only be used by one application at a time.\n\nThe purpose of this patch is to extend the RTC code so that we can\nmultiplex multiple applications event needs onto a single RTC device.\nThis is done by utilizing the timerqueue infrastructure to manage\na list of events, which cause the RTC hardware to be programmed\nto fire an interrupt for the next event in the list.\n\nIn order to preserve the functionality of the exsting proc,/dev/ and\nsysfs interfaces, we emulate the different interrupt modes as follows:\n\nAIE: We create a rtc_timer dedicated to AIE mode interrupts. There is\nonly one per device, so we don\u0027t change existing interface semantics.\n\nUIE: Again, a dedicated rtc_timer, set for periodic mode, is used\nto emulate UIE interrupts. Again, only one per device.\n\nPIE: Since PIE mode interrupts fire faster then the RTC\u0027s clock read\ngranularity, we emulate PIE mode interrupts using a hrtimer. Again,\none per device.\n\nWith this patch, the rtctest.c application in Documentation/rtc.txt\npasses fine on x86 hardware. However, there may very well still be\nbugs, so greatly I\u0027d appreciate any feedback or testing!\n\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\nLKML Reference: \u003c1290136329-18291-4-git-send-email-john.stultz@linaro.org\u003e\nAcked-by: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nReviewed-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Alessandro Zummo \u003ca.zummo@towertech.it\u003e\nCC: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCC: Richard Cochran \u003crichardcochran@gmail.com\u003e\n" }, { "commit": "78d89ef40c2ff7265df077e20c4d76be7d415204", "tree": "68503b0252682a496495b7adb46f6aa278db88ae", "parents": [ "47367a3ba425d70467af0009782098235ddbf204" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Tue Mar 31 15:24:48 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 01 08:59:24 2009 -0700" }, "message": "rtc: convert LEAP_YEAR into an inline\n\n- the LEAP_YEAR macro is buggy - it references its arg multiple times.\n Fix this by turning it into a C function.\n\n- give it a more approriate name\n\n- Move it to rtc.h so that other .c files can use it, instead of copying it.\n\nCc: dann frazier \u003cdannf@hp.com\u003e\nAcked-by: Alessandro Zummo \u003calessandro.zummo@towertech.it\u003e\nCc: stephane eranian \u003ceranian@googlemail.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "73442daf2ea85e2a779396b76b1a39b10188ecb5", "tree": "5705d69476b29890cd39ea3efdc8de68f38daebc", "parents": [ "b4a49b12e879ce79f495cc318c4b33caec6922e8" ], "author": { "name": "Jan Altenberg", "email": "jan.altenberg@linutronix.de", "time": "Tue Sep 02 14:36:05 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 02 19:21:40 2008 -0700" }, "message": "rtc_time_to_tm: fix signed/unsigned arithmetic\n\ncommit 945185a69daa457c4c5e46e47f4afad7dcea734f (\"rtc: rtc_time_to_tm: use\nunsigned arithmetic\") changed the some types in rtc_time_to_tm() to\nunsigned:\n\n void rtc_time_to_tm(unsigned long time, struct rtc_time *tm)\n {\n- register int days, month, year;\n+ unsigned int days, month, year;\n\nThis doesn\u0027t work for all cases, because days is checked for \u003c 0 later\non:\n\nif (days \u003c 0) {\n\tyear -\u003d 1;\n\tdays +\u003d 365 + LEAP_YEAR(year);\n}\n\nI think the correct fix would be to keep days signed and do an appropriate\ncast later on.\n\nSigned-off-by: Jan Altenberg \u003cjan.altenberg@linutronix.de\u003e\nCc: Maciej W.
