Question

最近，我正在做一些关于无线网络的研究，为了实现我的实验目标，必须对mac80211_hwsim进行一些更改，但是找不到与特定版本的Ubuntu相对应的内核源代码？如果有人能告诉我如何解决这个问题，那将会很有帮助。谢谢！

Answer 1

使用以下命令获取当前系统内核的源代码：

sudo apt-get source linux-source

There is a good reference with more details

Answer 2

您是否要对mac80211_hwsim内核模块进行更改？如果需要，你必须下载Linux 3.16的代码，你可以在linux / drivers / net / wireless / mac80211_hwsim.c找到代码。

您可以轻松找到有关下载和在线设置内核环境的资料。
