Subject: [x86] 9724330ed6: kernel-selftests.x86.fsgsbase_restore_64.fail
Greeting,
FYI, we noticed the following commit (built with gcc-11):
commit: 9724330ed6ddddf7aae3a57ab04292e4c138eb3a ("x86: asm: instrument usercopy in get_user() and __put_user_size()")
https://git.kernel.org/cgit/linux/kernel/git/melver/linux.git review/kmsan
in testcase: kernel-selftests
version: kernel-selftests-x86_64-37f3cb9b-1_20220704
with following parameters:
group: x86
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 16G
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
please be noted we also observed other tests failed on this commit, but pass on
parent, as below. as well as a segfault.
