(ipv4|ipv6) # * COMM_TYPE (netlink|ioctl) # Communication type between kernel and user space # for basic setup: enabling and assigning IP addresses # to the virtual ethernet devices. (Uses 'ip' command for netlink # and 'ifconfig' for ioctl.) # # Tests communication with ip (uses netlink) and ifconfig (uses ioctl) # over a device which is not visible from the current network namespace. # # There are two test cases which are trying to set an ip address on the veth1 # device which is not inside the network namespace referred to by NS_HANDLE0: # 1. using netlink (ip command). # 2. using ioctl (ifconfig command). #============================================================================== TCID="netns_breakns_$1_$2_$3" TST_TOTAL=2 . netns_helper.sh # SETUP netns_setup $1 $2 $3 "192.168.0.2" "192.168.0.3" "fd00::2" "fd00::3" tst_resm TINFO "NS interaction: $1 | devices setup: $3" # TEST CASE #1 $NS_EXEC $NS_HANDLE0 $NS_TYPE ip address add $IP1/$NETMASK dev veth1 2>/dev/null if [ $? -ne 0 ]; then tst_resm TPASS "controlling device over netlink" else tst_resm TFAIL "controlling device over netlink" fi # TEST CASE #2 tst_require_cmds ifconfig $NS_EXEC $NS_HANDLE0 $NS_TYPE ifconfig veth1 $IFCONF_IN6_ARG $IP1/$NETMASK 2>/dev/null if [ $? -ne 0 ]; then tst_resm TPASS "controlling device over ioctl" else tst_resm TFAIL "controlling device over ioctl" fi tst_exit
