如何在不重命名传递给insmod的.ko的情况下重命名内核模块名称? [英] How to rename a kernel module name without renaming the .ko passed to insmod?

问题描述

我需要重命名已经存在的驱动程序的内核模块(使用lsmod显示的名称)，而无需更改源文件的名称.

I need to rename a kernel module (the name that get displayed with lsmod) of an already existing driver without changing the name of the source file.

例如

# insmod xxx.ko
<<module loads successfully>>
# lsmod
Module                  Size  Used by    Tainted: P
xxx                   191527  0
#

• 我想将 xxx 重命名为 yyy .

  • I want to rename xxx to yyy.

    现在，我知道更改驱动程序源文件的名称(当它涉及单个文件时)会更改模块的名称.

    Now I know that changing the name of the driver source file (when it involves a single file) changes the name of the module.

    但是我不想更改源文件的名称.

    But I don't want to change the name of a source file.

    推荐答案

    在Makefile中重命名obj-m并将obj-m的依赖项设置为原始模块.

    Rename your obj-m in Makefile and set dependency of obj-m to original module.

    例如，我有一个包含所有源代码的文件hello.c.但我希望模块为mynewname.

    For example, I have file hello.c that contain all of my source code. But I want module to be mynewname.

    这是执行此操作的整个Makefile:

    Here is whole Makefile that does this:

    obj-m := mynewname.o 
    mynewname-objs := hello.o
    
    KERNELDIR ?= /lib/modules/$(shell uname -r)/build
    PWD  := $(shell pwd)
    
    default:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules
    
    clean:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) clean
    

    我将obj-m设置为mynewname.o，并使mynewname.o依赖于hello.o.调用make后，您将获得mynewname.ko.

    I set obj-m to mynewname.o and make mynewname.o dependant on hello.o. After invoking make you'll get mynewname.ko.
