Merge branch 'dsa-selftests'
Vladimir Oltean says: ==================== DSA selftests When working on complex new features or reworks it becomes increasingly difficult to ensure there aren't regressions being introduced, and therefore it would be nice if we could go over the functionality we already have and write some tests for it. Verbally I know from Tobias Waldekranz that he has been working on some selftests for DSA, yet I have never seen them, so here I am adding some tests I have written which have been useful for me. The list is by no means complete (it only covers elementary functionality), but it's still good to have as a starting point. I also borrowed some refactoring changes from Joachim Wiberg that he submitted for his "net: bridge: forwarding of unknown IPv4/IPv6/MAC BUM traffic" series, but not the entirety of his selftests. I now think that his selftests have some overlap with bridge_vlan_unaware.sh and bridge_vlan_aware.sh and they should be more tightly integrated with each other - yet I didn't do that either :). Another issue I had with his selftests was that they jumped straight ahead to configure brport flags on br0 (a radical new idea still at RFC status) while we have bigger problems, and we don't have nearly enough coverage for the *existing* functionality. One idea introduced here which I haven't seen before is the symlinking of relevant forwarding selftests to the selftests/drivers/net/<my-driver>/ folder, plus a forwarding.config file. I think there's some value in having things structured this way, since the forwarding dir has so many selftests that aren't relevant to DSA that it is a bit difficult to find the ones that are. While searching for applications that I could use for multicast testing (not my domain of interest/knowledge really), I found Joachim Wiberg's mtools, mcjoin and omping, and I tried them all with various degrees of success. In particular, I was going to use mcjoin, but I faced some issues getting IPv6 multicast traffic to work in a VRF, and I bothered David Ahern about it here: https://lore.kernel.org/netdev/97eaffb8-2125-834e-641f-c99c097b6ee2@gmail.com/t/ It seems that the problem is that this application should use SO_BINDTODEVICE, yet it doesn't. So I ended up patching the bare-bones mtools (msend, mreceive) forked by Joachim from the University of Virginia's Multimedia Networks Group to include IPv6 support, and to use SO_BINDTODEVICE. This is what I'm using now for IPv6. Note that mausezahn doesn't appear to do a particularly good job of supporting IPv6 really, and I needed a program to emit the actual IP_ADD_MEMBERSHIP calls, for dev_mc_add(), so I could test RX filtering. Crafting the IGMP/MLD reports by hand doesn't really do the trick. While extremely bare-bones, the mreceive application now seems to do what I need it to. Feedback appreciated, it is very likely that I could have done things in a better way. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
