* * Move the BasicDOSProtector.cs to OpenSim.Framework (all useful classes ↵teravus2013-10-071-1/+29
| | | | | | belong there.....) * Add an IsBlocked(string Key) method so it can be used more generically. (think.. if we want to rate limit login failures, we could have a call in the Login Service to IsBlocked(uuid.ToString()) and ignore the connection if it returns true, if IsBlocked returns false, we could run the login information and if the login fails we could run the Process method to count the login failures.

| | | | | | | | | HTTP Server handlers. XMLRPC Handler, GenericHttpHandler and <Various>StreamHandler * Applied the XmlRpcBasicDOSProtector.cs to the login service as both an example, and good practice. * Applied the BaseStreamHandlerBasicDOSProtector.cs to the friends service as an example of the DOS Protector on StreamHandlers * Added CircularBuffer, used for CPU and Memory friendly rate monitoring. * DosProtector has 2 states, 1. Just Check for blocked users and check general velocity, 2. Track velocity per user, It only jumps to 2 if it's getting a lot of requests, and state 1 is about as resource friendly as if it wasn't even there.

* Reinsert client.SceneAgent checks into ↵Justin Clark-Casey (justincc)2013-09-252-11/+29
| | | | | | | | LLUDPServer.HandleCompleteMovementIntoRegion() to fix race condition regression in commit 7dbc93c (Wed Sep 18 21:41:51 2013 +0100) This check is necessary to close a race condition where the CompleteAgentMovement processing could proceed when the UseCircuitCode thread had added the client to the client manager but before the ScenePresence had registered to process the CompleteAgentMovement message. This is most probably why the message appeared to get lost on a proportion of entity transfers. A better long term solution may be to set the IClientAPI.SceneAgent property before the client is added to the manager.

* Instead of swallowing any socket begin/end receive exceptions, log them for ↵Justin Clark-Casey (justincc)2013-09-251-7/+32

| | | | | | | | | | Patch taken from http://opensimulator.org/mantis/view.php?id=4905 originally by Greg C. Fixed to apply to r/23314 commit ba9daf849e7c8db48e7c03e7cdedb77776b2052f (cherry picked from commit 4ff9fbca441110cc2b93edc7286e0e9339e61cbe)

* When giving items between avatars in different simulators, only add the item ↵Oren Hurvitz2013-09-211-9/+44
| | | | | | to the receiving avatar's inventory once. When a user gives an item, the user's client sends an InventoryOffered IM message to its simulator. This adds the item to the receiver's inventory. If the receiver isn't in the same simulator then XMLRPC is used to forward the IM to the correct simulator. The bug was that the receiving simulator handled the message by calling OnInstantMessage() again, which added a second copy of the item to the inventory. Instead, the receiving simulator should only notify the avatar that the item was offered.

* Make UUID.Zero resolve to "Unknown User" in user cache.Justin Clark-Casey (justincc)2013-09-201-0/+2
| | | | | This is to avoid massive numbers of 'no user found' logs when user IDs are missing for some reason. UUID.Zero should not be used for any user ID.
* Lock around read/write of ScenePresence.m_originRegionID to make sure that ↵Justin Clark-Casey (justincc)2013-09-201-5/+33
| | | | | | all threads are seeing the latest value and not a cached one. There is a possibilty that some V2 teleport failures are due to the viewer triggered CompleteMovement thread not seeing the change of m_originRegionID by the UpdateAgent thread.

* BulletSim: reduce avatar walking stopped threshold.Robert Adams2013-09-202-0/+4

* BulletSim: zero velocity when avatar not moving.Robert Adams2013-09-201-0/+1

* Make new regions PG by default instead of Mature.Justin Clark-Casey (justincc)2013-09-201-1/+1

This is specified in the MaxOutgoingTransferVersion attribute of [EntityTransfer] in OpenSim.ini, see OpenSimDefaults.ini for more details.

* Revert "Also check user authorization if looking to upgrade from a child to ↵Justin Clark-Casey (justincc)2013-09-191-13/+0
| | | | | | | a root agent." This reverts commit c7ded0618c303f8c24a91c83c2129292beebe466. This proves not to be necessary - the necessary checks are already being done via QueryAccess() before cross or teleport
* Create regression TestCrossOnSameSimulatorNoRootDestPerm() to check that ↵Justin Clark-Casey (justincc)2013-09-192-1/+88

* Double the time spent waiting for a UseCircuitCode packet in ↵Justin Clark-Casey (justincc)2013-09-181-1/+1
| | | | | | | | | LLUDPServer.HandleCompleteMovementIntoRegion() This is to deal with one aspect of http://opensimulator.org/mantis/view.php?id=6755 With the V2 teleport arrangements, viewers appear to send the single UseCircuitCode and CompleteAgentMovement packets immediately after each other Possibly, on occasion a poor network might drop the initial UseCircuitCode packet and by the time it retries, the CompleteAgementMovement has timed out and the teleport fails. There's no apparant harm in doubling the wait time (most times only one wait will be performed) so trying this.

| | | | | | | LLUDPServer.HandleCompleteMovementIntoRegion() Add more information on which endpoint sent the packet when we have to wait and if we end up dropping the packet Only check if the client is active - other checks are redundant since they can only failed if IsActve = false
