Subject: [PATCH net-next 5/5] selftests: drv-net: add a trivial ping test
Add a very simple test for testing with a remote system.
Both IPv4 and IPv6 connectivity is optional so tests
will XFail is env doesn't define an address for the given
family.
Using netdevsim:
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1
# 1..2
# ok 1 ping.ping_v4
# ok 2 ping.ping_v6
# # Totals: pass:2 fail:0 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
Command line SSH:
$ NETIF=virbr0 EP_TYPE=ssh EP_ARGS=root@....168.122.123 \
LOCAL_V4=192.168.122.1 EP_V4=192.168.122.123 \
./tools/testing/selftests/drivers/net/ping.py
KTAP version 1
1..2
ok 1 ping.ping_v4
ok 2 ping.ping_v6 # XFAIL
# Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0
Existing devices placed in netns (and using net.config):
$ cat drivers/net/net.config
NETIF=veth0
EP_TYPE=netns
EP_ARGS=red
LOCAL_V4="192.168.1.1"
EP_V4="192.168.1.2"
$ ./run_kselftest.sh -t drivers/net:ping.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: ping.py
# KTAP version 1
# 1..2
# ok 1 ping.ping_v4
# ok 2 ping.ping_v6 # XFAIL
# # Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0
