selftests: Update fib_tests to handle missing ping6

2019-10-05T11:13:17Z

[ Upstream commit 0360894a05ed52be268e3c4d40b2df9d94975fa6 ] Some distributions (e.g., debian buster) do not install ping6. Re-use the hook in pmtu.sh to detect this and fallback to ping.

ipv6: do not free rt if FIB_LOOKUP_NOREF is set on suppress rule

2019-10-05T11:13:14Z

[ Upstream commit ca7a03c4175366a92cee0ccc4fec0038c3266e26 ] Commit 7d9e5f422150 removed references from certain dsts, but accounting for this never translated down into the fib6 suppression code. This bug was triggered by WireGuard users who use wg-quick(8), which uses the "suppress-prefix" directive to ip-rule(8) for routing all of their internet traffic without routing loops. The test case added here causes the reference underflow by causing packets to evaluate a suppress rule.

selftests: fib_tests: Fix 'Command line is not complete' errors

2019-04-11T21:17:59Z

A couple of tests are verifying a route has been removed. The helper expects the prefix as the first part of the expected output. When checking that a route has been deleted the prefix is empty leading to an invalid ip command: $ ip ro ls match Command line is not complete. Try option "help" Fix by moving the comparison of expected output and output to a new function that is used by both check_route and check_route6. Use the new helper for the 2 checks on route removal. Also, remove the reset of 'set -x' in route_setup which overrides the user managed setting.

selftests: fib_tests: sleep after changing carrier. again.

2019-02-24T02:34:20Z

Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.

fib_tests: Add tests for invalid metric on route

2018-10-05T18:58:50Z

Add ipv4 and ipv6 test cases with an invalid metrics option causing ip_metrics_convert to fail. Tests clean up path during route add. Also, add nodad to to ipv6 address add.

net/ipv6: Revert attempt to simplify route replace and append

2018-07-04T06:22:13Z

NetworkManager likes to manage linklocal prefix routes and does so with the NLM_F_APPEND flag, breaking attempts to simplify the IPv6 route code and by extension enable multipath routes with device only nexthops. Revert f34436a43092 and these followup patches: 6eba08c3626b ("ipv6: Only emit append events for appended routes"). ce45bded6435 ("mlxsw: spectrum_router: Align with new route replace logic") 53b562df8c20 ("mlxsw: spectrum_router: Allow appending to dev-only routes") Update the fib_tests cases to reflect the old behavior.
