[drm/mgag200] 90f479ae51: vm-scalability.median -18.8% regression

by kernel test robot

Greeting, FYI, we noticed a -18.8% regression of vm-scalability.median due to commit: commit: 90f479ae51afa45efab97afdde9b94b9660dd3e4 ("drm/mgag200: Replace struct mga_fbdev with generic framebuffer emulation") https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: vm-scalability on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with

[cpuidle] 259231a045: will-it-scale.per_process_ops -12.6% regression

by kernel test robot

Greeting, FYI, we noticed a -12.6% regression of will-it-scale.per_process_ops due to commit: commit: 259231a045616c4101d023a8f4dcc8379af265a6 ("cpuidle: add poll_limit_ns to cpuidle_device structure") https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next.git master in testcase: will-it-scale on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory with following parameters: nr_task: 100% mode: process test: mmap1 cpufreq_governor: performance test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two. test-url: https://github.com/antonblanchard/will-it-scale If you fix the issue, kindly add following

7c7d574801 ("kasan: detect negative size in memory operation .."): PANIC: early exception 0xe3 IP 10:ffffffffb04836c2 error 2 cr2 0x0

by kernel test robot

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://github.com/0day-ci/linux/commits/Walter-Wu/kasan-detect-negative-... commit 7c7d574801777b176b38fb68d37b77d7be9b9ca3 Author: Walter Wu <walter-zh.wu(a)mediatek.com> AuthorDate: Mon Oct 14 23:58:45 2019 +0800 Commit: 0day robot <lkp(a)intel.com> CommitDate: Tue Oct 15 13:06:53 2019 +0800 kasan: detect negative size in memory operation function KASAN missed detecting size is negative numbers in memset(), memcpy(), and memmove(), it will cause underflow bug, so needs to be detected by KASAN. If size is negative numbers, then it has three reasons to be defined as heap-out-of-bounds bug type. 1) Casting negative numbers to size_t would indeed turn up as a large size_t and its value will be larger than ULONG_MAX/2, so that this can qualify as out-of-bounds. 2) If KASAN has new bug type and user-space passes negative size, then there are duplicate reports. So don't produce new bug type in order to prevent duplicate reports by some systems (e.g. syzbot) to report the same bug twice. 3) When size is negative numbers, it may be passed from user-space. So we always print heap-out-of-bounds in order to prevent that kernel-space and user-space have the same bug but have duplicate reports.
