python - What needs to be done to import and use a Linux kernel module in python?

Question

What do I need to do import a Linux kernel module into python so that I can use its features in an application I want to build.

My target is to use the Better Approach To Mobile Ad-Hoc Networking (B.A.T.M.A.N) kernel module that has been included in the Linux Kernel since 2.6 for routing purposes for a mesh network that would consist of Raspberry Pis. I will be using Twisted for all the network programming.

Answer 1

您不想加载内核模块。内核模块有许多非常奇怪的属性（例如，一些指令被编译为无操作，然后根据处理器在加载时替换。）

相反，将代码重新编译到可以从 Python 调用的用户空间库中会简单得多。

更简单的是，你可以抓住 BATMAN 算法的“用户空间”分支，称为 batmand 并使用它。http://www.open-mesh.org/projects/open-mesh/wiki/BranchesExplained

Answer 2

触发将该模块加载到内核中。将其加载到用户空间进程中可能是徒劳的。从理论上讲，您可以使用内核模块的源代码在 C 中构建 Python 模块，但这仍然不能为您提供例如硬件访问权限，并且您还必须模拟/复制大部分内核基础设施。听起来是个坏主意。
