6c44cecc64 Cedar: Bind the special listeners to the specified IP address 2018-12-15 21:33:37 +01:00
Daiyuu Nobori
58e2f74f7f Added the "OpenVPNPushDummyIPv4AddressOnL2Mode" option for the OpenVPN L2 mode.
To fix the bug of OpenVPN 2.4.6 and particular version of kernel mode TAP driver on Linux, the TAP device must be up after the OpenVPN client is connected. However there is no direct push instruction to do so to OpenVPN client. Therefore we push the dummy IPv4 address (RFC7600) to the OpenVPN client to enforce the TAP driver UP state.

6a45921f41 OpenVPN: Add packet scrambling/obfuscation feature
This allows an OpenVPN client to bypass a firewall which is aware of the protocol and is able to block it.
The XOR mask set on the server has to be the same on the client, otherwise it will not be able to connect with certain obfuscation modes.
A special OpenVPN client built with the "XOR patch" is required in order to use this function, because it has never been merged in the official OpenVPN repository.

Two parameters are added to the server configuration: "OpenVPNObfuscationMethod" and "OpenVPNObfuscationMask".
Their value can be retrieved with "OpenVpnObfuscationGet" and set with "OpenVpnObfuscationEnable" in the VPN Command Line Management Utility.

8abcf3d0a9 Debug flag and test mode improvements
1. ifdef DEBUG -> defined(_DEBUG) || defined(DEBUG)
In VC++ compilers, the macro is "_DEBUG", not "DEBUG".

2. If set memcheck = true, the program will be vitally slow since it will log all malloc() / realloc() / free() calls to find the cause of memory leak.
For normal debug we set memcheck = false.
Please set memcheck = true if you want to test the cause of memory leaks.
