From 427acb71fc8574406a70d41a1f775c0354768cf5 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Fri, 12 Mar 2021 01:03:22 +0200 Subject: libcap: import from packages feed Having libcap in OpenWrt base allows us to enable libcap support in other packages in base. In lldpd, this would allow the monitor process to drop its privileges instead of running as root, improving security. It will also allow us to drop our patch to disable libcap.
