-- Implements functionality related to Server Message Block (SMB, also known
-- as CIFS) traffic, which is a Windows protocol.
--
-- SMB traffic is normally sent to/from ports 139 or 445 of Windows systems. Other systems
-- implement SMB as well, including Samba and a lot of embedded devices. Some of them implement
-- it properly and many of them not. Although the protocol has been documented decently
-- well by Samba and others, many 3rd party implementations are broken or make assumptions.
-- Even Samba's and Windows' implementations aren't completely compatiable. As a result,
-- creating an implementation that accepts everything is a bit of a minefield.
--
-- Where possible, this implementation, since it's intended for scanning, will attempt to
-- accept any invalid implementations it can, and fail gracefully if it can't. This has
-- been tested against a great number of weird implementations, and it now works against
-- all of them.
--
-- The intention of this library is to eventually handle all aspects of the SMB protocol.
-- That being said, I'm only implementing the pieces that I (Ron Bowes) need. If you
-- require something more, let me know and I'll put it on my todo list.
--
-- A programmer using this library should already have some knowledge of the SMB protocol,
-- although a lot isn't necessary. You can pick up a lot by looking at the code. The basic
-- login/logoff is this:
--
-- <code>
-- [connect]
-- C->S SMB_COM_NEGOTIATE
-- S->C SMB_COM_NEGOTIATE
-- C->S SMB_COM_SESSION_SETUP_ANDX
-- S->C SMB_COM_SESSION_SETUP_ANDX
-- C->S SMB_COM_TREE_CONNECT_ANDX
-- S->C SMB_COM_TREE_CONNECT_ANDX
-- ...
-- C->S SMB_COM_TREE_DISCONNECT
-- S->C SMB_COM_TREE_DISCONNECT
-- C->S SMB_COM_LOGOFF_ANDX
-- S->C SMB_COM_LOGOFF_ANDX
-- [disconnect]
-- </code>
--
-- In terms of functions here, the protocol is:
--
-- <code>
-- status, smbstate = smb.start(host)
-- status, err = smb.negotiate_protocol(smbstate, {})
-- status, err = smb.start_session(smbstate, {})
-- status, err = smb.tree_connect(smbstate, path, {})
-- ...
-- status, err = smb.tree_disconnect(smbstate)
-- status, err = smb.logoff(smbstate)
-- status, err = smb.stop(smbstate)
-- </code>
--
-- The <code>stop</code> function will automatically call tree_disconnect and logoff,
-- cleaning up the session, if it hasn't been done already.
--
-- To initially begin the connection, there are two options:
--
-- 1) Attempt to start a raw session over 445, if it's open.
--
-- 2) Attempt to start a NetBIOS session over 139. Although the
-- protocol's the same, it requires a <code>session request</code> packet.
-- That packet requires the computer's name, which is requested
-- using a NBSTAT probe over UDP port 137.
--
-- Once it's connected, a <code>SMB_COM_NEGOTIATE</code> packet is sent, requesting the protocol
-- "NT LM 0.12", which is the most commonly supported one. Among other things, the server's
-- response contains the host's security level, the system time, and the computer/domain name.
-- Some systems will refuse to use that protocol and return "-1" or "1" instead of 0. If that's
-- detected, we kill the connection (because the protocol following won't work).
--
-- If that's successful, <code>SMB_COM_SESSION_SETUP_ANDX</code> is sent. It is essentially the logon
-- packet, where the username, domain, and password are sent to the server for verification.
-- The username and password are generally picked up from the program parameters, which are
-- set when running a script, or from the registry where it can be set by other scripts (for
-- example, <code>smb-brute.nse</code>). However, they can also be passed as parameters to the
-- function, which will override any other username/password set.
--
-- If a username and password are set, they are used for the first login attempt. If a login fails,
-- or they weren't set, a connection as the 'GUEST' account with a blank password is attempted. If
-- that fails, then a NULL session is established, which should always work. The username/password
-- will give the highest access level, GUEST will give lower access, and NULL will give the lowest
-- (often, NULL will give no access).
--
-- The actual login protocol used by <code>SMB_COM_SESSION_SETUP_ANDX</code> is explained in detail
-- in <code>smbauth.lua</code>.
--
-- Thanks go to Christopher R. Hertel and his book Implementing CIFS, which
-- taught me everything I know about Microsoft's protocols. Additionally, I used Samba's
-- list of error codes for my constants. Although I don't believe they would be covered
-- by GPL, since they're public now anyways, but I'm not a lawyer and, if somebody feels
-- differently, let me know and we can sort this out.
--
-- Scripts that use this module can use the script arguments listed below
-- example of using these script arguments:
-- <code>
-- nmap --script=smb-<script>.nse --script-args=smbuser=ron,smbpass=iagotest2k3,smbbasic=1,smbsign=force <host>
-- </code>
--
-- @args smbbasic Forces the authentication to use basic security, as opposed to "extended security".
-- Against most modern systems, extended security should work, but there may be cases
-- where you want to force basic. There's a chance that you'll get better results for
-- enumerating users if you turn on basic authentication.
-- @args smbsign Controls whether or not server signatures are checked in SMB packets. By default, on Windows,
-- server signatures aren't enabled or required. By default, this library will always sign
-- packets if it knows how, and will check signatures if the server says to. Possible values are:
-- * <code>force</code>: Always check server signatures, even if server says it doesn't support them (will
-- probably fail, but is technically more secure).
-- * <code>negotiate</code>: [default] Use signatures if server supports them.
-- * <code>ignore</code>: Never check server signatures. Not recommended.
-- * <code>disable</code>: Don't send signatures, at all, and don't check the server's. not recommended.
-- More information on signatures can be found in <code>smbauth.lua</code>.
-- @args smbport Override the default port choice. If <code>smbport</code> is open, it's used. It's assumed
-- to be the same protocol as port 445, not port 139. Since it probably isn't possible to change
-- Windows' ports normally, this is mostly useful if you're bouncing through a relay or something.
-- @args randomseed Set to a value to change the filenames/service names that are randomly generated.
