hi,
I test ipv6_ping by "./fcnal-test.sh -v -t ipv6_ping".
There are two tests failed.
TEST: ping out, VRF bind - ns-B IPv6 LLA [FAIL]
TEST: ping out, VRF bind - multicast IP [FAIL]
While in fcnal-test.sh the expected command result is 2, the result is 1, so the test failed.
ipv6_ping_vrf()
{
......
for a in ${NSB_LINKIP6}%${VRF} ${MCAST}%${VRF}
do
log_start
show_hint "Fails since VRF device does not support linklocal or multicast"
run_cmd ${ping6} -c1 -w1 ${a}
log_test_addr ${a} $? 2 "ping out, VRF bind"
done
The ipv6_ping test output is attached.
Did I set something wrong result that these tests failed?
best regards,
Adding David and Zhijian.

ping6 is failing as it should. Can you send a patch to change the
expected rc from 2 to 1?
hi,
man ip, the output about exit value is like following.
"Exit status is 0 if command was successful, and 1 if there is a syntax error. If an error was reported by the kernel exit status is 2."
Did the following COMMAND have syntax error? If not, should I still change the expected rc from 2 to 1?

strace of ping6 shows it is failing with '1'.
As for 'ip', it returns the exit code of the command run. iproute2 code,
lib/exec.c, cmd_exec().
