command hangs in CentOS 7 arm64 container with Ubuntu 22 amd64 host Description of problem: The command hangs in the container, taking over the CPU: ``` $ docker run -it centos:7 [root@42e655bf3d60 /]# LD_DEBUG=all /lib64/ld-2.17.so --list /usr/bin/true & [1] 74 [root@42e655bf3d60 /]# 74: file=/usr/bin/true [0]; generating link map [root@42e655bf3d60 /]# ps -e -o pid,ppid,etime,time,state,args PID PPID ELAPSED TIME S COMMAND 1 0 34:59 00:00:00 S /usr/libexec/qemu-binfmt/aarch64-binfmt-P /bin/bash /bin/bash 74 1 03:16 00:03:13 R /usr/libexec/qemu-binfmt/aarch64-binfmt-P /lib64/ld-2.17.so /lib64/ld-2.17.so 80 1 4-19:34:01 00:00:00 R ps -e -o pid,ppid,etime,time,state,args [root@42e655bf3d60 /]# ``` Steps to reproduce: 1. Start container 2. Run `/lib64/ld-2.17.so --list /usr/bin/true` Additional information: 1. The problem is not observed in an Ubuntu 20.04 host system performing the same scenario. 2. My team build environment has amd64 native architecture hardware. I ran a similar scenario on an AWS arm64 native machine (QEMU is not needed) and the command works fine in the container. 3. My team builds several Linux images daily - about a dozen amd64 and eight arm64. This is the only image that's causing us this problem. 4. I built trace-cmd but when I tried to start a trace it told me `No events enabled with kvm`. 5. I built qemu-8.1.0-rc3 and saw the same behavior but I don't think `/usr/libexec/qemu-binfmt/aarch64-binfmt-P` was replaced with a new version so I don't think the old version was used for my container.
