From c5ab9b1c41f6d89d84fe147e51fe623f90bd026c Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Sun, 11 Aug 2019 10:35:49 +0300 Subject: [PATCH] drop_monitor: Require CAP_NET_ADMIN for drop monitor configuration Currently, the configure command does not do anything but return an error. Subsequent patches will enable the command to change various configuration options such as alert mode and packet truncation. Similar to other netlink-based configuration channels, make sure only users with the CAP_NET_ADMIN capability set can execute this command. Signed-off-by: Ido Schimmel Signed-off-by: David S.
