A hash-based DOS attack on Btrfs Pascal Junod has discloseda pair of denial-of-service attacks against the Btrfs filesystem based on hash collisions. " I have created several files with random names in a directory (around 500). The time required to remove them is negligible. Then, I have created the same number of files, but giving them only 55 different crc32c values. The time required to remove them is so large that I was not able to figure it out and killed the process after 220 minutes (!)." This is a local attack only, but administrators of Btrfs-using sites with untrusted users may want to pay attention. | 5:05p |

Each of these new features are still in active development, and should be approached with some care." There's a lot of other new features and a number of performance improvements as well. |
