udp: only do GSO if # of segs > 1

2019-10-07T17:01:51+00:00

[ Upstream commit 4094871db1d65810acab3d57f6089aa39ef7f648 ] Prior to this change an application sending <= 1MSS worth of data and enabling UDP GSO would fail if the system had SW GSO enabled, but the same send would succeed if HW GSO offload is enabled. In addition to this inconsistency the error in the SW GSO case does not get back to the application if sending out of a real device so the user is unaware of this failure. With this change we only perform GSO if the # of segments is > 1 even if the application has enabled segmentation. I've also updated the relevant udpgso selftests.

selftests/powerpc: Retry on host facility unavailable

[ Upstream commit 6652bf6408895b09d31fd4128a1589a1a0672823 ] TM test tm-unavailable must take into account aborts due to host aborting a transactin because of a facility unavailable exception, just like it already does for aborts on reschedules (TM_CAUSE_KVM_RESCHED).

selftests: Update fib_nexthop_multiprefix to handle missing ping6

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

2019-10-05T13:11:13+00:00

[ 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.

kselftests: cgroup: add freezer mkdir test

2019-09-12T21:04:40+00:00

Add a new cgroup freezer selftest, which checks that if a cgroup is frozen, their new child cgroups will properly inherit the frozen state. It creates a parent cgroup, freezes it, creates a child cgroup and populates it with a dummy process. Then it checks that both parent and child cgroup are frozen.

selftest: A few cleanups for fib_nexthops.sh

2019-09-05T09:59:39+00:00

Cleanups of the tests in fib_nexthops.sh 1. Several tests noted unexpected route output, but the discrepancy was not showing in the summary output and overlooked in the verbose output. Add a WARNING message to the summary output to make it clear a test is not showing expected output. 2. Several check_* calls are missing extra data like scope and metric causing mismatches when the nexthops or routes are correct - some of them are a side effect of the evolving iproute2 command. Update the data to the expected output. 3. Several check_routes are checking for the wrong nexthop data, most likely a copy-paste-update error. 4. A couple of tests were re-using a nexthop id that already existed. Fix those to use a new id.

tc-testing: don't hardcode 'ip' in nsPlugin.py
