在3.10.0-862.14.4.el7.x86_64 下,因没有驱动所以自行编译驱动并加载后,系统自动重启。编译过程中没有报错 [root@localhost test]# uname -a Linux localhost 3.10.0-862.14.4.el7.x86_64 #1 SMP Wed Sep 26 15:12:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# gcc -v 使用内建 specs。 COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-pc-linux-gnu/7.3.0/lto-wrapper 目标:x86_64-pc-linux-gnu 配置为:../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib 线程模型:posix gcc 版本 7.3.0 (GCC)

后来发现使用cat /boot/config-$(uname -r)| grep CONFIG_RETPOLINE命令,如果返回CONFIG_RETPOLINE=y的话,那么使用sys_call_table方法hook sys_execve函数是行不通的,需要使用jprobe方法来进行hook 解决方法是在3.10.0-862.14.4.el7.x86_64版本下,使用jprobe方法重新编译驱动
Sorry, something went wrong.
