From e54c7bcbf14a25dc3a913b4c808b52121c522e9b Mon Sep 17 00:00:00 2001 From: Ian Kent Date: Fri, 8 Sep 2017 16:16:27 -0700 Subject: autofs: make disc device user accessible The autofs miscellanous device ioctls that shouldn't require CAP_SYS_ADMIN need to be accessible to user space applications in order to be able to get information about autofs mounts. The module checks capabilities so the miscelaneous device should be fine with broad permissions.
