c20bcb2e60 Mayaqua/Network: Skip IPv6 nameservers for SecureNAT 2021-04-27 07:30:38 +00:00
Davide Beatrici
0472f9c286 Rewrite DNS API from scratch into dedicated file(s) 
From a functional point of view, the main improvement is that GetIP() now always prioritizes IPv6 over IPv4.
The previous implementation always returned an IPv4 address, unless not available: in such case it failed.
This means that now connections to hostnames should be established via IPv6 if available.

From a programmer point of view, getting rid of the insane wrappers is enough to justify a complete rewrite.

As an extra, several unrelated unused global variables are removed.

1708998a11 Change IP structure so that IPv4 addresses are stored in RFC3493 format 
In addition to saving 4 bytes for each instantiation, this change makes IP-related operations faster and clearer.

84588095d5 Mayaqua/Network.c: Always use fcntl() to toggle socket non-blocking mode (UNIX) 
O_NONBLOCK is standardized by POSIX, as opposed to FIONBIO.

This commit also fixes a bug: fcntl() was only called to disable the mode.

0570f7d31c Mayaqua/Network: add StopUdpListener() 
This allows to stop a UDP listener without deleting it.

It's especially useful when no datagrams should be received anymore, but there are other threads accessing the listener.

f0357d4000 - Fixed the problem occurs when RPC messages between Cluster Members exceed 64Kbytes. 
- Fixed the RADIUS PEAP client to use the standard TLS versioning.
- Implementation of a function to fix the MAC address of L3 VPN protocol by entering e.g. "MAC: 112233445566" in the "Notes" field of the user information.
- Implementation of a function to fix the virtual MAC address to be assigned to the L3 VPN client as a string attribute from RADIUS server when authentication.

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.

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."
