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.

Fix LibreSSL support 
My previous patch used a wrong if directive, which disabled removed
(de)initialization and threading for LibreSSL. This most likely causes
issues at runtime.

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.

98443715d9 Fixed the vulnerability that a malformed packet will cause the buffer overflow at the receive path. This vulnerability may occur abnormal process exit with the buffer security check mechanism built-in with SoftEther VPN binary. Although this buffer overflow can theoretically bypass the security check in theory, in the actual binary it is detected by the buffer security check inserted by the C compiler and the process is forcibly terminated. Therefore, as a result, it can be abused by a DoS attacker. Acknowledgments: The last problems is discovered and reported by Fabrizio Steiner. 2019-02-28 20:40:23 +09:00

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.

09ee19e72b Mayaqua/Network.c: fix double free crash in GetCipherList() 
SSL_free() also frees the associated context.

d6c3c1896c/ssl/ssl_lib.c (L1209)

From https://www.openssl.org/docs/man1.1.1/man3/SSL_free.html:

"SSL_free() also calls the free()ing procedures for indirectly affected items, if applicable: the buffering BIO, the read and write BIOs, cipher lists specially created for this ssl, the SSL_SESSION. Do not explicitly free these indirectly freed up items before or after calling SSL_free(), as trying to free things twice may lead to program failure."
