// TODO - figure out how to automate testing of this.
//	    Being all interactive and involving external web servers / viewers makes it hard.

// TODO - do all the setup on first run, and check if needed on each start up, to be self healing.

// TODO - pepper could be entered on the console on startup if it's not defined, as a master password sort of thing.
//	    I'd go as far as protecting the database credentials that way, but legacy OpenSim needs it unprotected.
//	    Also keep in mind, people want autostart of their services without having to enter passwords on each boot.

// TODO - once it is event driven, periodically run things like session clean ups, self healing, and the secure.sh thing.
//	    And backups off course.
//	    As well as regular database pings to keep the connection open.

IG and CG now both have sims connected to other grids, so some sort of
multi database solution would be good, then we can run the grid and the
external sims all in one.

Not sure if this'll work with Count(*).

---------------------------------------------

The complicated bit is the binds.

You are binding field values to C memory locations.
The parameters and returned fields need binds.
Mostly seems to be the value parts of the SQL statements.

I suspect most will be of the form - 
  ... WHERE x=? and foo=?
  INSERT INTO table VALUES (?,?,?)
  UPDATE table SET x=?, foo=? WHERE id=?

  A multi table update -
  UPDATE items,month SET items.price=month.price WHERE items.id=month.id;

/* TODO -

    On new user / password reset.
.	Both should have all the same security concerns as the login page, they are basically logins.
.	Codes should be "very long", "(for example, 16 case-sensitive alphanumeric characters)"
.    "confirm" button hit on "accountCreationPage" or "resetPasswordPage"
.	generate a new token, keep it around for idleTimeOut (or at least 24 hours), call it .linky instead of .lua
.	    hash the linky for the file name, for the same reason we hash the hashish with pepper for the leaf-node.
.	    Include user level field, new users get -200.
.	    Store the linky itself around somewhere we can find it quickly for logged in users.
.		store it in the regenerated session
.		Scratch that, we should never store the raw linky, see above about hashing the linky.

.	    The linky is just like the session token, create it in exactly the same way.
.		Linky is base64() of the binary, so it's short enough to be a file name, and not too long for the URL.
.		But we only get to send one of them as a linky URL, no backup cookies / body / headers.
.	    Sooo, need to separate the session stuff out of Rd->stuff.
.		Use two separate qhashtbl's, Rd->session and Rd->linky.

	For new user
.	    create their /opt/opensim_SC/var/lib/users/UUID.lua account record, and symlink firstName_lastName.lua to it.
.	    They can log on, 
	    but all they can do is edit their email to send a new validation code, and enter the validation code.
	    They can reset their password.
.	    Warn them on login and any page refresh that there is an outstanding validation awaiting them.
	For reset password
.	    Let them do things as normal, in case this was just someone being mean to them, coz their email addy might be public.
.	    Including the usual logging out and in again with their old password.
.	    Warn them on login and any page refresh that there is an outstanding password reset awaiting them.
+	email linky, which is some or all of the token result bits strung together, BASE64 encode the result.
.	regenerate the usual token
.    user clicks on the linky (or just enters the linky in a field)
.	validate the linky token.
	    compare the level field to the linky type in the linky URL, new users -200 would be "../validateUser/.." and not "../resetPassword/.."
.	delete the linky token
.	    Particularly important for the forgotten password email, since now that token is in the wild, and is used to reset a password.
	    	Which begs the question, other than being able to recieve the email, how do we tell it's them?
		    Security questions suck, too easily guessed.
		    Ask their DoB.  Still sucky, coz "hey it's my birthday today" is way too leaky.
		    This is what Multi Factor Autentication is good for, and that's on the TODO list.
		    Also, admins should have a harder time doing password resets.
			Must be approved by another admin?
			Must log onto the server via other means to twiddle something there?
	For password reset page
	    Ask their DoB to help confirm it's them.
		validate the DoB, delete tokens and back to the login page if they get it wrong
		Should warn people on the accountCreationPage that DoB might be used this way.
	    ask them for the new password, twice
	    Create a new passwordSalt and passwordHash, store them in the auth table.
	For validate new user page
.	    tell them they have validated
	    create their OpenSim account UserAccounts.UserTitle and auth tables, not GridUser table
	    create their GridUser record.
.	    update their UserAccounts.Userlevel and UserAccounts.UserTitle
.	    send them to the login page.
.	regenerate the usual token
?	let user stay logged on?
	    Check best practices for this.

    Check password strength.
	https://stackoverflow.com/questions/549/the-definitive-guide-to-form-based-website-authentication?rq=1
	    Has some pointers to resources in the top answers "PART V: Checking Password Strength" section.

    "PART VI: Much More - Or: Preventing Rapid-Fire Login Attempts"  and  "PART VII: Distributed Brute Force Attacks" is also good for -
    Login attempt throttling.
    Deal with dictionary attacks by slowing down access on password failures etc.

    Deal with editing yourself.
    Deal with editing others, but only as god.


    Regularly delete old session files and ancient newbies.


    Salts should be "lengthy" (128 bytes suggested in 2007) and random.  Should be per user to.  Or use a per user and a global one, and store the global one very securely.
	And store hash(salt+password).
	On the other hand, the OpenSim / SL password hashing function may be set in concrete in all the viewers.  I'll have to find out.
	    So far I have discovered -
		On login server side if the password doesn't start with $1$, then password = "$1$" + Util.Md5Hash(passwd);
		remove the "$1$ bit
		string hashed = Util.Md5Hash(password + ":" + data.Data["passwordSalt"].ToString());
		if (data.Data["passwordHash"].ToString() == hashed)
		    passwordHash is char(32), and as implied above, doesn't include the $1$ bit.  passwordSalt is also char(32)
		Cool VL and Impy at least sends the $1$ md5 hashed version over the wire.
		    Modern viewers obfuscate the details buried deep in C++ OOP crap.
		Sent via XMLRPC
		MD5 is considered broken since 2013, possibly longer.
	Otherwise use a slow hashing function.  bcrypt?  scrypt?  Argon2?  PBKDF2?
	    https://security.stackexchange.com/questions/211/how-to-securely-hash-passwords
    Should include a code in the result that tells us which algorithm was used, so we can change the algorithm at a later date.  /etc/passwd does this.
	Which is what the $1$ bit currently used between server and client is sorta for.

+    Would be good to have one more level of this Rd->database stuff, so we know the type of the thing.
	While qhashtbl has API for putting strings, ints, and memory, it has none for finding out what type a stored thing is.
	Once I have a structure, I add things like "level needed to edit it", "OpenSim db structure to Lua file mapping", and other fanciness.
	Would also help with the timestamp being stored for the session, it prints out binary gunk in the DEBUG <div>.
	Starting to get into object oriented territory here.  B-)
	    I'll have to do it eventually anyway.
	    object->tostring(object), and replace the big switch() statements in the existing db code with small functions.
		That's why the qLibc stuff has that format, coz C doesn't understand the concept of passing "this" as the first argument.

/* Four choices for the token -  (https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html)
    https://en.wikipedia.org/wiki/Cross-site_request_forgery
	Has some more info.

Large random value generated by a secure method (getrandom(2)).
    Keep it secret, put it in hidden fields, or custom HTTP header (requires JavaScript but more secure than hidden fields).
    NOT cookies or GET.  Don't log it.
Cryptographically sign a session ID and timestamp.
    Timestamp is for session timeouts.
    Keep it secret, put it in hidden fields, or custom HTTP header (requires JavaScript but more secure than hidden fields).
    Needs a secret key server side.
A strong HMAC (SHA-256 or better) of a session ID and timestamp.
    The above document seems to imply that a key is used for this, the openssl EVP functions don't mention any way of supplying this key.
	https://en.wikipedia.org/wiki/HMAC says there is a key as well.
	https://www.openssl.org/docs/man1.1.0/man3/HMAC.html  HAH!  They can have keys.  OpenSSL's docs suck.
    Token = HMAC(sessionID+timestamp)+timestamp (Yes, timestamp is used twice).
    Keep it secret, put it in hidden fields, or custom HTTP header (requires JavaScript but more secure than hidden fields).
    Needs a secret key server side.
Double cookie
    Large random value generated by a secure method set as a cookie and hidden field.  Check they match.
    Optional - encrypt / salted hash it in another cookie / hidden field.
+	Also a resin (BASE64 session key in the query string).
	    Not such a good idea to have something in the query, coz that screws with bookmarks.
	https://security.stackexchange.com/questions/59470/double-submit-cookies-vulnerabilities
	    Though so far all the pages I find saying this don't say flat out say "use headers instead", though they do say "use HSTS".
	https://security.stackexchange.com/questions/220797/is-the-double-submit-cookie-pattern-still-effective
+	    Includes a work around that I might already be doing.
TODO - think it through, is it really secure against session hijacking?
TODO - document why we redirect POST to GET, coz it's a pain in the arse, and we have to do things twice.

SOOOOO - use double cookie + hidden field.
    No headers, coz I need JavaScript to do that.
    No hidden field when redirecting post POST to GET, coz GET doesn't get those.
    pepper		= long pass phrase or some such stored in .sledjChisl.conf.lua, which has to be protected dvs1/opensimsc/0640 as well as the database credentials.
    salt		= large random value generated by a secure method (getrandom(2)).
    seshID		= large random value generated by a secure method (getrandom(2)).
    timeStamp		= mtime of the leaf-node file, set to current time when we are creating the token.
    sesh		= seshID + timeStamp
    munchie		= HMAC(sesh) + timeStamp	The token	hidden field
    toke_n_munchie	= HMAC(UUID + munchie)		The token	cookie
    hashish		= HMACkey(toke_n_munchie, salt)	Salted token	cookie & linky query
?    resin		= BASE64(hashish)		Base64 token	cookie
    leaf-node		= HMACkey(hashish, pepper)	Stored token	file name

    Leaf-node.lua (mtime is timeStamp)
	IP, UUID, salt, seshID, user name, passwordSalt, passwordHash (last two for OpenSim password protocol)

    The test -  (validateSesh() below)
	we get hashish and toke_n_munchie
	HMACkey(hashish + pepper)	-> leaf-node
	read leaf-node.lua		-> IP, UUID, salt, seshID
	get it's mtime			-> timeStamp
	seshID + timeStamp		-> sesh
	HMAC(sesh) + timeStamp		-> munchie
	    if we got munchie in the hidden field, compare it
	toke_n_munchie == HMAC(UUID + munchie)
	    For linky it'll be -
	    HMAC(UUID + munchie) 	-> toke_n_munchie
	hashish == HMACkey(toke_n_munchie + salt)
+	If it's too old according to mtime, delete it and logout.

I should make it easy to change the HMAC() function.  Less important for these short lived sessions, more important for the linky URLs, most important for stored password hashes.
    Same for the pepper.

The required JavaScript might be like https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html#xmlhttprequest--native-javascript-
    NOTE - they somehow fucked up that anchor tag.

NOTE - storing a pepper on the same RAID array as everything else will be a problem when it comes time to replace one of the disks.
	It might have failed badly enough that you can't wipe it, but an attacker can dumpster dive it, replace the broken bit (firmware board), and might get lucky.
	Also is a problem with SSD and rust storing good data on bad sectors in the spare sector pool, wear levelling, etc.

I think this means send a new cookie.

    https://www.w3.org/Protocols/
	Still nothing official, though the ENV / HEADER stuff tends to be about the protocol things, and cookies / body / queries are about the data things.
    http://docs.gantry.org/gantry4/advanced/setby
	Says that query overrides cookies, but that might be just for their platform.
    https://framework.zend.com/manual/1.11/en/zend.controller.request.html
	Says - "1. GET, 2. POST, 3. COOKIE, 4. SERVER, 5. ENV."
	    We don't actually get the headers directly, it's all sent via the env.

URL query	Values actually provided by the user in the FORM, and other things.
POST body	Values actually provided by the user in the FORM.
cookies		
    https://stackoverflow.com/questions/4056306/how-to-handle-multiple-cookies-with-the-same-name

headers		includes HTTP_COOKIE and QUERY_STRING
env		includes headers and HTTP_COOKIE and QUERY_STRING

database	Since all of the above are for updating the database anyway, this goes on the bottom, overridden by all.
		    Though be wary of security stuff.

    Sending cookie headers is a special case, multiples can be sent, otherwise headers are singletons, only send one for each name.

	But then so is the silly fcgi2 SDK, which basically assumes it's a CGI wrapper, not proper FCGI.
