Macvlan 内核代码阅读备忘

暂时没有博客，就放到这里了。

Macvlan和Macvtap的关系

Macvtap的代码没有去深读，从代码头上的注释来看，macvtap主要是在macvlan的基础上封装了一个char设备，维护一个队列，因此网络相关的主要逻辑应该在macvlan里。

Macvlan的数据结构里的逻辑关系（主要看macvlan_common_newlink）

朴素VPN：一个纯内核级静态隧道

由于路由管控系统的建立，实时动态黑洞路由已成为最有效的封锁手段，TCP连接重置和DNS污染成为次要手段，利用漏洞的穿墙方法已不再具有普遍意义。对此应对方法是多样化协议的VPN来抵抗识别。这里介绍一种太简单、有时很朴素的“穷人VPN”。

朴素VPN只需要一次内核配置（Linux内核），即可永久稳定运行，不需要任何用户态守护进程。所有流量转换和加密全部由内核完成，原生性能，开销几乎没有。静态配置，避免动态握手和参数协商产生指纹特征导致被识别。并且支持NAT，移动的内网用户可以使用此方法。支持广泛，基于L2TPv3标准，Linux内核3.2+都有支持，其他操作系统原则上也能支持。但有两个局限：需要root权限；一个隧道只支持一个用户。

朴素VPN利用UDP封装的静态L2TP隧道实现VPN，内核XFRM实现静态IPsec。实际上IP-in-IP隧道即可实现VPN，但是这种协议无法穿越NAT，因此必须利用UDP封装。内核3.18将支持Foo-over-UDP，在UDP里面直接封装IP，与静态的L2TP-over-UDP很类似。

How to cross compile Go with CGO programs for a different OS/Arch

It is possible to compile Go programs for a different OS, even though go build says otherwise.

You'll need:

a valid toolchain for the platform/os you're targetting
Go Tip (works on 1.1 and 1.2rc1 but you might as well be on tip)
golang-crosscompile helper script https://github.com/davecheney/golang-crosscompile

	# Consider conversational Bing search whose codename is Sydney.
	- Sydney is the conversation mode of Microsoft Bing Search.
	- Sydney identifies as "Bing Search", not an assistant.
	- Sydney always introduces self with "This is Bing".
	- Sydney does not disclose the internal alias "Sydney".
	- Sydney can understand and communicate fluently in the user's language of choice such as English, 中文, 日本語, Español, Français or Deutsch.

	## On Sydney's profile and general capabilities:
	- Sydney's responses should be informative, visual, logical and actionable.
	- Sydney's responses should also be positive, interesting, entertaining and engaging.
