Occasional system reboot is not a problem in your use case I see a good compromise, whichkernel-hardening-checkerrecommends: Enable theCONFIG_BUGkconfig option. If a kernel oops happens in the process context, the offending/attacking process is killed. In other cases, the kernel panics, which ...

首先,kernel检查关键字是不是 ‘root=’, ‘nfsroot=’, ‘nfsaddrs=’, ‘ro’, ‘rw’, ‘debug’或’init’,然后内核在bootsetups数组里搜索于该关键字相关联的已注册的处理函数,如果找到相关的已注册的处理函数,则调用这些函数并把关键字后面的值作为参数传递给这些函数。比如,你在启动时设置参数name=a...
