v93 v94 21 21 * Container based on red-black trees 22 22 * Replaced AVL trees and B+trees 23 23 24 * The kernel used to pass kernel addresses of IPC phone objects (a.k.a. phone hashes) as connection identifiers to userspace. This intentional but unfortunate information leak was replaced in this release by purely user-defined labels negotiated during IPC connection setup handshake. Each connected phone now has a user-defined label and imprints this label on each IPC call which is routed through it. 24 25 * In 2014 HelenOS got its own implementation of RCU (Read-Copy-Update) synchronization primitive along with a CHT (Concurrent Hash Table) data type based on RCU. Although sophisticated and interesting from the technological point of view, the RCU and CHT were mostly unused and unmaintained. We therefore decided to remove these very complex features.
