selftests: net: reuseport_dualstack: fix uninitalized parameter

2019-11-01T22:11:02Z

This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN) occasionally due to the uninitialized length parameter. Initialize it to fix this, and also use int for "test_family" to comply with the API standard.

udp: only do GSO if # of segs > 1

2019-10-03T15:47:10Z

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.

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

2019-09-26T07:34:25Z

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.
