(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 that a separate network namespace can configure and communicate # over the devices it sees. Tests are done using netlink(7) ('ip' command) # or ioctl(2) ('ifconfig' command) for controlling devices. # # There are three test cases: # 1,2. communication over paired veth (virtual ethernet) devices # from two different network namespaces (each namespace has # one device) # 3. communication over the lo (localhost) device in a separate # network namespace #============================================================================== TCID="netns_comm_$1_$2_$3" TST_TOTAL=3 . 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 $tping -q -c2 -I veth0 $IP1 1>/dev/null if [ $? -eq 0 ]; then tst_resm TPASS "configuration and communication over veth0" else tst_resm TFAIL "configuration and communication over veth0" fi # TEST CASE #2 $NS_EXEC $NS_HANDLE1 $NS_TYPE $tping -q -c2 -I veth1 $IP0 1>/dev/null if [ $? -eq 0 ]; then tst_resm TPASS "configuration and communication over veth1" else tst_resm TFAIL "configuration and communication over veth1" fi # TEST CASE #3 case "$2" in ipv4) IP_LO="127.0.0.1" ;; ipv6) IP_LO="::1" ;; esac case "$3" in netlink) $NS_EXEC $NS_HANDLE0 $NS_TYPE ip link set dev lo up || \ tst_brkm TBROK "enabling lo device failed" ;; ioctl) $NS_EXEC $NS_HANDLE0 $NS_TYPE ifconfig lo up || \ tst_brkm TBROK "enabling lo device failed" ;; esac $NS_EXEC $NS_HANDLE0 $NS_TYPE $tping -q -c2 -I lo $IP_LO 1>/dev/null if [ $? -eq 0 ]; then tst_resm TPASS "configuration and communication over localhost" else tst_resm TFAIL "configuration and communication over localhost" fi tst_exit
