selftests: forwarding: Have lldpad_app_wait_set() wait for unknown, too

2018-10-11T05:22:07Z

Immediately after mlxsw module is probed and lldpad started, added APP entries are briefly in "unknown" state before becoming "pending". That's the state that lldpad_app_wait_set() typically sees, and since there are no pending entries at that time, it bails out. However the entries have not been pushed to the kernel yet at that point, and thus the test case fails. Fix by waiting for both unknown and pending entries to disappear before proceeding.

selftests: forwarding: lib: Add mtu_set(), mtu_restore()

2018-09-20T14:46:02Z

Some selftests need to tweak MTU of an interface, and naturally should at teardown restore the MTU back to the original value. Add two functions to facilitate this MTU handling: mtu_set() to change MTU value, and mtu_reset() to change it back to what it was before.

selftests: forwarding: Move DSCP capture to lib.sh

2018-08-01T16:52:30Z

dscp_capture_install() and dscp_capture_uninstall() are going to be useful for a test added by a following patch, move them therefore to lib.sh together with related helpers. While doing so, change the rule preference from mere DSCP value to DSCP+100 in order to support adding captures of packets with DSCP of 0.

selftests: forwarding: Move lldpad waiting to lib.sh

2018-08-01T16:52:30Z

The function lldpad_wait() will be useful for a test added by a following patch. Likewise would the "sleep 5" with its extensive comment. Therefore move lldpad_wait() to lib.sh in order to allow reuse. Rename it to lldpad_app_wait_set() to recognize that what this is intended to wait on are the pending APP sets. For the sleeping, add a function lldpad_app_wait_del(). That will serve to hold the related explanatory comment (which edit for clarity), and as a token in the caller to identify the sites where this sort of waiting takes place. That will serve when/if a better way to handle this business is found. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: Introduce $ARPING

2018-07-30T16:47:21Z

Instead of relying on "arping" being installed everywhere under that name, introduce a variable $ARPING like the other tools do. Convert an existing test, mirror_gre_vlan_bridge_1q.sh to require_command $ARPING and then invoke arping through the variable. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: lib: Add require_command()

2018-07-30T16:47:21Z

The logic for testing whether a certain command is available is used several times in the current code base. The tests in follow-up patches add more requirements like that. Therefore extract the logic into a named function, require_command(), that can be used directly from lib.sh as well as from any test that wishes to declare dependence on some command.
