Description

We've had one or two reports lately of people seeing

[warn] Unexpected onionskin length after decryption: 58

in their logs.

It basically means that some client sent the relay a malformed (too short) create cell.

It's possible that this is a bug in our Tor client code, but I think it's more likely that somebody else is working on a Tor client, and has a bug in their code.

Since there isn't really much the relay operator can do about it, we should probably downgrade the warning to a protocol-warn.
