From bf635ed091dee333f4458eec617a4124b51322fc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20Br=C3=BCns?= Date: Sat, 1 Oct 2016 20:41:42 +0200 Subject: sandbox/fs: Use readdir instead of deprecated readdir_r MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using readdir_r limits the maximum file name length and may even be unsafe, and is thus deprecated in since glibc 2.24.
