From 313e4f0fe0eecf9316716535c2a1100a369fa934 Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Mon, 6 Oct 2014 00:49:02 +0100 Subject: [PATCH] udp: Report authbind exit status as errno value if it seems appropriate authbind-helper is documented as indicating an errno value in its exit status. When the exit status is small enough that it's unlikely to have come from the runtime system, print it as an errno value instead of using lg_exitstatus.
