[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 80G memory
with following parameters:
runtime: 300s
size: 8T
test: anon-cow-seq-hugetlb
cpufreq_governor: performance
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email

[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 tag
Reported-by: kernel test robot <rong.a.chen(a)intel.com>
Details are as below:

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

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.
KASAN report:
