Just wanted to share the good news and properly mark this as "Fixed Internally".

Hopefully it'll be included in a viewer + server update coming soon.

Today, one of my sims got griefed, and the griefer was completely immune to TP home, estate ban and freeze.

We tried :

• Teleporting the griefer home via the World -> Region / Estate -> Region -> Teleport Home One User
• Teleporting the griefer home via the World -> Region / Estate -> Estate -> Kick User From Estate
• Adding the griefer to the estate ban list for all estates I own.

We did all of the above multiple times and NOTHING worked, no matter how many times we tried.

He stood there laughing at us, saying he was immortal and couldn't be sent home.
Then returned to griefing us.

We couldn't even freeze him, because he was using some sort of modified client which bypassed freezes.

I tried setting the sim to verified avatars only, but this did NOT boot him.
I could have restarted the sim to get rid of him, but that would have been very annoying to my residents who were using it at the time.

I should not have to rely on other sims being up in order to teleport griefers off the sims I have paid for.

This ability for griefers to render themselves immune to TP home via crashing their home sim is an exploit.

It should be treated as such, and fixed ASAP.

LL should fix the TP Home command so that in the rare cases where a subject's home sim is down when you try to send them home, they are simply logged off, or at the very least sent to a random public sim on the grid - away from your sim.

Beyond that, more needs to be done to make sims harder to crash. I'd also like to see automated sim monitoring which detects when someone tries to crash a sim and automatically suspends their account for it.

Griefers shouldn't have the ability to crash sims at all, and they certainly should not be able to go around crashing sims at will, completely immune to even estate-level ejects and bans.

I'm sending the repro for this new, slightly different bug to security@lindenlab.com, because I don't want the knowledge of how to become immune to TP home to get into the public domain. I think that a bug which allows banned people to stay in locations they are banned from meets the security@ criteria of "permits unauthorized access to Second Life/Linden Lab resources".

Thanks to Thomas Shikami, who pointed this out and explained this to me. I just hope it gets fixed :/

So, what I fixed what that if, in the process of teleport, you were expressly not able to get home because of estate management, that it would generate a new teleport home for you. Now, it might be that other situations where you can't teleport home aren't caught and filtered through this code - that's possible.

I would point out that the bug stated that that we reset homes for those who don't have permission to be there, not homes that are on sims that are down. We specifically didn't do that because if you teleport home in the normal action of working in SL, and that Sim happens to be down, you don't want your home to be reset. In terms of just adjusting where they end up if the sim is down, the system already does that and has done for quite a while.

I think it's more likely there's a different bug here wereby the act of forcing a TP on someone else is not being passed through the appropriate code. However, as I said, that wasn't what the original bug was that was fixed.
That being said, I'll take a look into this shortly.

any time a teleport fails because the destination is...

-invalid (no longer exists)
-down
-access list
-banned

The user should be re-routed to info hub. I don't think the home point needs to be reset per say just re-route to nearest info hub.

Torley will be able to tell you when this code goes live.
