>From 4b6c7969a5174aa87b5dad5caa9d9ca31ecbad87 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= <berrange@redhat.com> Date: Tue, 30 Apr 2019 17:27:41 +0100 Subject: [PATCH 3/6] logging: restrict sockets to mode 0600 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The virtlogd daemon's only intended client is the libvirtd daemon. As such it should never allow clients from other user accounts to connect. The code already enforces this and drops clients from other UIDs, but we can get earlier (and thus stronger) protection against DoS by setting the socket permissions to 0600 Reviewed-by: Ján Tomko <jtomko@redhat.com> Signed-off-by: Daniel P.
