Massive Roadrunner

基于Funtrace的针对RunC底层代码的分析工具。模块更新中。

Description

用于静态分析RunC的源代码。在functrace的基础上，实现两个定位模块:

• 函数级的搜索模块：给定一个函数名、或者函数参数的名称后，能够通过AST定位到runc调用链中满足条件的目标函数（或者包含给定参数的函数）
• 函数内部的搜索模块：给定了一个函数的参数，能够跟踪函数内部对这个参数进行操作的语句

Install

Sample

For Examples/a.go:

package Examples

func a(q int, w int, e int) int {
	return b(q, w, e)
}
func b(q1 int, q2 int, q3 int) int {
	return q1 + q2 + q3 + 1
}
func main() {
	a(1, 2, 3)

}

Analysis result is the following and saved in data/Examples/a.json

[
  {
    "Package": "Examples",
    "Name": "a",
    "Exported": false,
    "Receiver": [],
    "Params": [
      {
        "Name": "q",
        "Type": "int"
      },
      {
        "Name": "w",
        "Type": "int"
      },
      {
        "Name": "e",
        "Type": "int"
      }
    ],
    "Results": [
      {
        "Name": "",
        "Type": "int"
      }
    ]
  },
  {

    "Name": "b",
    "Exported": false,
    "Receiver": [],

      },
      {
        "Name": "q2",
        "Type": "int"
      },
      {
        "Name": "q3",
        "Type": "int"
      }
    ],
    "Results": [
      {
        "Name": "",
        "Type": "int"
      }
    ]
  },
  {
    "Package": "Examples",
    "Name": "main",
    "Exported": false,
    "Receiver": [],

    "Results": []
  }

Usage

To analysis and save and query structured AST tree.

To analysis and save and query structured AST tree.

Usage:
astool analysis <file>
astool locate <function>
astool trace <function>:<arg>
astool -h
astool -v

Options:
analysis <file>         :To analysis target file and gather useful information. 
locate <function>       :To locate function by name. Be sure all files you need to search were resolved successfully before.
trace <function>:<arg>  :To trace the statement inside the function that operates on this parameter.
-h                      :Show this screen.
-v                      :Show version.

分析后的文件存放在./data/<packname>/<filename>.json.

Attention

• While inputting filepath, DON'T use \ as separators. Use / instead.

TODO

• Batch process files
• Better performance
• Limited workspace?
• Database added for analysis data?
• Bad AST handle
• ...
