Hello,
The attached patch is to delete the judgment of whether it is the root user
when using "traceroute -s".When we use "traceroute -s" command as a non-root
regular user, a "you must be root" error occurs due to the validation of
whether getuid() is equal to 0. Even if CAP_NET_RAW permission is configured by
"setcap cap_net_raw+ep /bin/busybox", non-root users cannot use "traceroute -s"
as well. We consider that finer grained permission control can be achieved
through the capabilities(CAP) mechanism, rather than directly verifying whether
it is a root user.Kindly check the patch.
