wireshark添加address sanitizer参数编译

原文地址：https://www.cnblogs.com/liqinglucky/p/wireshark_memory_check.html

在ubuntu系统wireshark源码编译文中已经会编译wireshark了。现在对wireshark的CMakeLists.txt中添加内存检测工具address sanitizer。这样就可以对wireshark程序代码做内存检测功能。

一 添加编译参数

改动很简单，只需在wireshark的CMakeLists.txt中添加address sanitizer编译参数

add_compile_options(-fsanitize=address -fsanitize-recover=all -fsanitize=leak) 
add_link_options(-fsanitize=address -fsanitize-recover=all -fsanitize=leak) 

git diff如下

wireshark-4.0.2# ls
CMakeLists.txt                  

wireshark-4.0.2# git diff
diff --git a/CMakeLists.txt b/CMakeLists.txt
index 092dc7b..a9cad7a 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -1452,6 +1452,9 @@ if (QT_FOUND)
        endif()
 endif()

+add_compile_options(-fsanitize=address -fsanitize-recover=all -fsanitize=leak)
+add_link_options(-fsanitize=address -fsanitize-recover=all -fsanitize=leak)
+
 if(ENABLE_CHECKHF_CONFLICT)
        set(ENABLE_CHECK_FILTER 1)
 endif()

然后编译。

二 测试内存检测功能

可以在wireshark源代码中加测试代码，也可以启动wireshark后，直接用窗口的关闭按钮退出窗口就会触发内存泄漏

测试日志如下：

wireshark-4.0.2/build# run/wireshark
 ** (wireshark:472217) 06:50:13.504868 [Capture MESSAGE] -- Capture Start ...

 ** (wireshark:472217) 06:51:04.131232 [Capture MESSAGE] -- Capture stopped.
