Dragonfly incorrectly handles a task structure’s usedTrac field

描述

### Impact The processPieceFromSource method (figure 4.1) is part of a task processing mechanism. The method writes pieces of data to storage, updating a Task structure along the way. The method does not update the structure’s usedTraffic field, because an uninitialized variable n is used as a guard to the AddTraffic method call, instead of the result.Size variable. ```golang var n int64 result.Size, err = pt.GetStorage().WritePiece([skipped]) result.FinishTime = time.Now().UnixNano() if n > 0 { pt.AddTraffic(uint64(n)) } ``` A task is processed by a peer. The usedTraffic metadata is not updated during the processing. Rate limiting is incorrectly applied, leading to a denial-of-service condition for the peer. ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).
