From 20e5fefb0c372ca804d5a3e4176bf1586ac37004 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Mon, 30 Apr 2018 13:15:54 -0700 Subject: [PATCH] sysctl: Protect hard/symlinks by default. There is no usecase for not protecting symlinks that I know of in OpenWrt. Not even on desktop systems where you have multiple users with a shell.
