Error disabling address space randomization: Operation not permitted

DockerContainer下gdb无法正常工作的解决办法

昨天想在Mac上使用gdb调试一个Linux下编译的动态链接库, 以正常选项启动一个docker container, 运行gdb却发现如下错误提示.

warning: Error disabling address space randomization: Operation not permitted
Cannot create process: Operation not permitted
During startup program exited with code 127.
(gdb)

在google搜索结果里第6个才找到正确答案, https://www.google.com/search?safe=off&q=docker+gdb+warning%3A+Error+disabling+address+space+randomization%3A+Operation+not+permitted+Cannot+create+process%3A+Operation+not+permitted+During+startup+program+exited+with+code+127&oq=docker+gdb+warning%3A+Error+disabling+address+space+randomization%3A+Operation+not+permitted+Cannot+create+process%3A+Operation+not+permitted+During+startup+program+exited+with+code+127, 原来是docker run中的一个不太常用的选项, docker run --privileged, 加上即可.

我的运行命令是：docker run --privileged -it  docker-kali-shared /bin/bash

原因：warning: Error disabling address space randomization: Operation not permitted

linux 内核为了安全起见，采用了Seccomp(secure computing)的沙箱机制来保证系统不被破坏。它能使一个进程进入到一种“安全”运行模式，该模式下的进程只能调用4种系统调用（system calls），即read(), write(), exit()和sigreturn()，否则进程便会被终止。

docker只有以--security-opt seccomp=unconfined的模式运行container才能利用GDB调试
