samples: pktgen: pass the environment variable of normal user to sudo
All pktgen samples can use the environment variable instead of option parameters(eg. $DEV is able to use instead of '-i' option). This is results of running sample as root and user: // running as root # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -v -n 1 Running... ctrl^C to stop // running as normal user $ DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -v -n 1 [...] ERROR: Please specify output device This results show the sample doesn't work properly when the sample runs as normal user. Because the sample is restarted by the function (root_check_run_with_sudo) to run with sudo. In this process, the environment variable of normal user doesn't propagate to sudo. It can be solved by using "-E"(--preserve-env) option of "sudo", which preserve normal user's existing environment variables. So this commit adds "-E" option in the function (root_check_run_with_sudo). Signed-off-by: Juhee Kang <claudiajkang@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
