From a89cebe1970fb0cd87d71e4524d6620c2b673369 Mon Sep 17 00:00:00 2001 From: Werner Fink <werner@suse.de> Date: Mon, 22 May 2017 12:17:53 +0200 Subject: [PATCH] Allow sysctl to print lines longer than 1024 chars as well do not open /proc/sys files if only the names of the system control names of the kernel parameters should be shown. Avoid leaking tmpname in case of a pattern mismatch.
