selftests: set sysctl bc_forwarding properly in router_broadcast.sh

2019-06-03T22:15:01Z

sysctl setting bc_forwarding for $rp2 is needed when ping_test_from h2, otherwise the bc packets from $rp2 won't be forwarded. This patch is to add this setting for $rp2. Also, as ping_test_from does grep "$from" only, which could match some unexpected output, some test case doesn't really work, like: # ping_test_from $h2 198.51.200.255 198.51.200.2 PING 198.51.200.255 from 198.51.100.2 veth3: 56(84) bytes of data. 64 bytes from 198.51.100.1: icmp_seq=1 ttl=64 time=0.336 ms When doing grep $form (198.51.200.2), the output could still match. So change to grep "bytes from $from" instead. Fixes: 40f98b9af943 ("selftests: add a selftest for directed broadcast forwarding") Signed-off-by: Xin Long Signed-off-by: David S. Miller

selftests: forwarding: Make ping timeout configurable

2019-02-01T23:26:36Z

The current timeout (2 seconds) proved to be too low for some (emulated) systems where we run the tests. Make the timeout configurable and default to 5 seconds. Signed-off-by: Ido Schimmel Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: add a selftest for directed broadcast forwarding

2018-07-29T19:37:06Z

As Ido's suggestion, this patch is to add a selftest for directed broadcast forwarding with vrf. It does the assertion by checking the src IP of the echo-reply packet in ping_test_from. Signed-off-by: Xin Long Signed-off-by: David S. Miller
