Description of problem: Anolis23 x86_64 ECS环境社区nightly kernel-selftests测net.reuseaddr_ports_exhausted.sh测试异常。 Version-Release number of selected component (if applicable): How reproducible: 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/ cd /tools/testing/selftests/net make ./reuseaddr_ports_exhausted.sh Actual results: [root@qibo-anolis23-nightly-func-x86-1 net]# ./reuseaddr_ports_exhausted.sh TAP version 13 1..3 #
