63caa4b07f Protocol.c: adapt ClientConnectGetSocket() for new proxy functions
The function has been greatly improved, here are some of the changes:

- The required SESSION (c->Session) parameter is checked correctly: the function returns immediately in case it's NULL. Previously, the function didn't return in case the parameter was NULL; multiple checks were in place, but not in all instances where the parameter was dereferenced.
- The resolved IP address is cached with all proxy types.
- The "RestoreServerNameAndPort" variable is documented.
- The Debug() messages have been improved.

b8f58a2f94 Move generic proxy stuff from Cedar to Mayaqua
This commit moves the generic (not related to our protocol) proxy stuff from Cedar to Mayaqua, in dedicated files.

The functions are refactored so that they all have the same arguments and follow the same logic.

Dedicated error codes are added, in order to indicate clearly why the function(s) failed.

5d73cd878f Proto_OpenVPN.c: improve OvsProcessData(), fix out-of-bounds access found by Coverity
Coverity Scan detected an out-of-bounds access issue: OvsProcessData() checked whether the payload size was bigger than the size of the buffer, instead of checking whether the entire packet size (payload size + 2 bytes) was, resulting in an out-of-bounds access in case the payload size is bigger than 1998.

This commit also improves the variable names, the comments and adds two Debug() lines.

16bde47763 Proto_OpenVPN.c: fix segmentation fault in OvsProceccRecvPacket()
OvsDecrypt() returns 0 when it fails, resulting in "size" rolling over with an end result of 4294967292.

This commit fixes the issue by checking whether "size" is greater than sizeof(UINT) before performing the subtraction.

7d58e6bf60 Add interface for easy protocol implementation
This commit adds a protocol interface to the server, its purpose is to manage TCP connections and the various third-party protocols.

More specifically, ProtoHandleConnection() takes care of exchanging the packets between the local and remote endpoint; the protocol implementation only has to parse them and act accordingly.

The interface knows which protocol is the connection for by calling IsPacketForMe(), a function implemented for each protocol.

d6cf1b85a9 Virtual: fix race condition in DHCP server which resulted in multiple clients receiving the same IP
A race condition in the DHCP server caused it to offer the same IP address to multiple clients when they connected at the same time, because an offered IP address was considered free until the final step (DHCP_ACK).

This commit introduces a list to keep track of the pending leases created during DHCP_OFFER, so that an IP address is guaranteed to be offered to a single client.

a97b87da68 Cedar/Admin.c: fix segmentation fault caused by non-initialized string in StGetServerCipherList()
StrCat() appends a string to an already existing string. In order to know where the existing string ends, it uses StrLen() which in turn uses strlen(), a function considered unsafe because it doesn't stop until it finds the null character.

Since the string was allocated but not initialized, StrCat() was either:

- Working correctly.
- Copying only a part of the string.
- Making the program crash via strlen().

The fix consists in using StrCpy(), which starts writing at the beginning of the string.

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.

3f5f716357 Revamp digest functions
- Hash() has been removed because it was ambiguous, Md5() and Sha0() are proper replacements.
- HMacMd5() and HMacSha1() now share a common implementation handled by the new Internal_HMac() function.
- NewMd() and MdProcess() now support plain hashing (without the key).
- NewMd(), SetMdKey() and MdProcess() now check the OpenSSL functions' return value and in case of failure a debug message is printed along with the error string, if available.
- SetMdKey()'s return value has been changed from void to bool, so that it's possible to know whether the function succeeded or not.
- MdProcess()' return value has been changed from void to UINT (unsigned int) and the function now returns the number of bytes written by HMAC_Final() or EVP_DigestFinal_ex().

32082eb8af Proto_IkePacket.c: fix and improve IkeHMac() function
Pull request #294 added SHA-256, SHA-384, and SHA-512 support to the protocol, but part of it was removed in faee11ff09, because it caused a buffer over-read crash.

It also broke the MD5 implementation because the switch-case block didn't handle the type anymore.

This pull request fixes all the implementations and improves the IkeHMac() function by using the dedicated hashing functions.

3e733eac6f Interop_OpenVPN.c: convert the cipher name to lowercase prior to calling EVP_get_cipherbyname()
OpenVPN sends the cipher name in uppercase, even if it's not standard, thus we have to convert it to lowercase for EVP_get_cipherbyname().

We also have to send the cipher name as it was received from the OpenVPN client, unless it's a different cipher, to prevent a message such as:
"WARNING: 'cipher' is used inconsistently, local='cipher AES-128-GCM', remote='cipher aes-128-gcm'"
It happens because OpenVPN uses "strcmp()" to compare the local and remote parameters: a6fd48ba36/src/openvpn/options.c (L3819-L3831)

See https://github.com/openssl/openssl/issues/6921 for EVP_get_cipherbyname().

59e1483dbf Put TUN down on client disconnect.
On startup client creates TUN interface in UP state and kept it UP even
if connection to the server was lost. Creating interface in DOWN state,
turning it UP on successful (re-)connection to server and DOWN on either
disconnect or connection loss would enable DHCP client (say dhclient5)
to detect necessity for lease renewal.

Added a client configuration parameter to create TUN interface in DOWN
state and commands to enable, disable, and query the configuration
parameter.
Enabling the parameter causes client to put all unused TUN interfaces
DOWN, create new TUN interfaces in DOWN state, and turn TUN interfaces
corresponding to active sessions DOWN on connection loss or
disconnecting from server.
Disabling the parameter forces client to turn all TUN interfaces UP and
create new TUN interfaces in UP state.
Default value is 'Disable'.
