In the Linux kernel, the following vulnerability has been resolved:net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rulesCT cleanup assumes that all tc rules were deleted first, and sois free to delete the CT shared resources (e.g the dr_actionfwd_action which is shared for ...

使用async_schedule调用module的probe函数,对于那些需要较多msleep的模块,这个方法可以通过并行提高init速度,但是一些模块对初始化顺序是有依赖的,所以慎用。 4. 优化设备IO驱动,提高数据的读写速度,kernel启动完成到android launcher完成,几乎无处不涉及到文件的读写,IO速度对启动时间的影响重大,代码是人写的,所以平台特...
memcpy(mem, buff, 5); //Read new value for (i = 0; i<5 ; i++) { printf("\nnew mem[%d]:%c", i, mem[i]); } printf("\n"; munmap (mem, 10); //destroy map memory close (fd); //close file return 0; } 1.
memcpy函数的功能是从源src所指的内存地址的起始位置开始拷贝n个字节到目标dest所指的内存地址的起始位置中。task[pid].task_entry = task[pid].thread.ip = (unsigned long)my_process让当前进程运行时调用my_process(void)。 下面是一些内联汇编,作用是调用函数框架,call eip改变eip,执行第一个进程,调用my_proce...

__init my_start_kernel(void)是一个主函数,系统入口。先初始化了一个PCB,即task[0],然后用for循环,用memcpy()系统函数复制PCB,再修改一些信息,初始化整个PCB数组。 memcpy函数的功能是从源src所指的内存地址的起始位置开始拷贝n个字节到目标dest所指的内存地址的起始位置中。task[pid].task_entry = task[pid...
