From 6804b725dcc99437e8dc1330447330b08e3c39b8 Mon Sep 17 00:00:00 2001 From: Dimitri Staessens Date: Tue, 15 Feb 2022 22:03:17 +0100 Subject: ipcpd: Fix initialization of hash width in DHT The width of the Kademlia hash function (dht->b) was set only after the ID was created. This should have failed miserably, but the bytes after were fine as they were just a randomized ID in the Kademlia network. Nasty.
