WebJan 28, 2024 · Created attachment 280687 [details] Sample driver code to showcase the bug Far time ago in the linux kernel was introduced helper function named div64_u64_rem. Today i found that this function gets wrong result for some input. Example: try to divide 0x8000000000000000ULL by 4299651251ULL via this helper function. http://visa.lab.asu.edu/gitlab/fstrace/android-kernel-msm-hammerhead-3.4-marshmallow-mr3/blob/30f8825c50f93524d7859e6594f15b8f9f852e9f/lib/div64.c ord to sfo today

http://www.bricktou.com/arch/x86/include/asm/div64div_u64_rem_en.html WebThe current implementation of div64_u64 for 32bit systems returns an approximately correct result when the divisor exceeds 32bits. Since doing 64bit division using 32bit hardware is a long since solved problem we just use one of the existing proven methods. Additionally, add a div64_s64 function to correctly handle doing signed 64bit division.
