Description of problem: kernel-selftest测试套ptrace.vmaccess用例执行fail,日志如下： [root@qibo-anolis8-nightly-func-arm-4 ptrace]# ./vmaccess TAP version 13 1..2 # Starting 2 tests from 1 test cases. # RUN global.vmaccess ... # OK global.vmaccess ok 1 global.vmaccess # RUN global.attach ... # attach: Test terminated by timeout # FAIL global.attach not ok 2 global.attach # FAILED: 1 / 2 tests passed. # Totals: pass:1 fail:1 xfail:0 xpass:0 skip:0 error:0 版本信息： [root@qibo-anolis8-nightly-func-arm-4 ~]# uname -r 5.10.134-264.git.53f303a6c3fa.an8.aarch64 [root@qibo-anolis8-nightly-func-arm-4 ~]# cat /etc/os-release NAME="Anolis OS" VERSION="8.6" ID="anolis" ID_LIKE="rhel fedora centos" VERSION_ID="8.6" PLATFORM_ID="platform:an8" PRETTY_NAME="Anolis OS 8.6" ANSI_COLOR="0;31" HOME_URL="https://openanolis.cn/" [root@qibo-anolis8-nightly-func-arm-4 ~]# free -h total used free shared buff/cache available Mem: 15Gi 229Mi 14Gi 11Mi 570Mi 14Gi Swap: 0B 0B 0B [root@qibo-anolis8-nightly-func-arm-4 ~]# lscpu Architecture: aarch64 Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per cluster: 4 Socket(s): 1 Cluster(s): 1 NUMA node(s): 1 Vendor ID: ARM BIOS Vendor ID: Alibaba Cloud Model: 1 Model name: Neoverse-N1 BIOS Model name: virt-rhel7.6.0 Stepping: r3p1 BogoMIPS: 50.00 NUMA node0 CPU(s): 0-3 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 atomics fphp asimdhp cpuid asimdrdm lrcpc dcpop asimddp ssbs Version-Release number of selected component (if applicable): How reproducible: 必现 Steps to Reproduce: rpm -ivh xxx.src.rpm 默认安装到/root下 yum-builddep -y rpmbuild/SPECS/kernel.spec 自动安装前置依赖包，需要yum-utils rpmbuild -bp ./rpmbuild/SPECS/kernel.spec # 这个步骤会打相关的patch， 解压缩tar包，生成BUILD目录 cd rpmbuild/BUILD/kernel-xxx/linux-xxx/ 接下来就可以编译测试了 cd /tools/testing/selftests/bpf/ make 执行相关用例： cd kernel-selftests/kernel-selftests/ptrace ./vmaccess Actual results: 用例执行fail Expected results: 用例执行pass Additional info: 已知问题，结论是：有修复补丁，经过测试有效，但未被社区接收，等待社区结论
