From f2ecc0d1b7d569b4b2c930c7450390c04778ee8a Mon Sep 17 00:00:00 2001 From: Roman Bogorodskiy Date: Thu, 8 Apr 2021 18:44:58 +0400 Subject: [PATCH] bhyve: fix regression in legacy virtio-9p config parsing Commit 621b5090487de9fed1b503769702a9a2a27cc7bb introduced a regression in legacy virtio-9p config parsing by not initializing *sharename to NULL. As a result, "sharename != NULL" check in the first iteration fails and bhyve exits with "virtio-9p: more than one share name given". Fix by adding NULL back.
