2022-07-29selftests: netdevsim: Add test cases for route deletion failureIdo Schimmel
Add IPv4 and IPv6 test cases that ensure that we are not leaking a reference on the nexthop device when we are unable to delete its associated route. Without the fix in a previous patch ("netdevsim: fib: Fix reference count leak on route deletion failure") both test cases get stuck, waiting for the reference to be released from the dummy device [1][2]. [1] unregister_netdevice: waiting for dummy1 to become free. Usage count = 5 leaked reference. fib_check_nh+0x275/0x620 fib_create_info+0x237c/0x4d30 fib_table_insert+0x1dd/0x1d20 inet_rtm_newroute+0x11b/0x200 rtnetlink_rcv_msg+0x43b/0xd20 netlink_rcv_skb+0x15e/0x430 netlink_unicast+0x53b/0x800 netlink_sendmsg+0x945/0xe40 ____sys_sendmsg+0x747/0x960 ___sys_sendmsg+0x11d/0x190 __sys_sendmsg+0x118/0x1e0 do_syscall_64+0x34/0x80 entry_SYSCALL_64_after_hwframe+0x63/0xcd [2] unregister_netdevice: waiting for dummy1 to become free.

2021-06-08selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEVPetr Machata
In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

2021-02-02selftests: Extend fib tests to run with and without flags notificationsAmit Cohen
Run the test cases with both `fib_notify_on_flag_change` sysctls set to '1', and then with both sysctls set to '0' to verify there are no regressions in the test when notifications are added.
