From 12d3767ba4c84c32150cbe6ff6494498780f12c9 Mon Sep 17 00:00:00 2001 From: "djm@openbsd.org" Date: Fri, 3 Mar 2017 06:13:11 +0000 Subject: [PATCH] upstream commit fix ssh-keygen -H accidentally corrupting known_hosts that contained already-hashed entries. HKF_MATCH_HOST_HASHED is only set by hostkeys_foreach() when hostname matching is in use, so we need to look for the hash marker explicitly.
