What do you mean by "I was *thinking*"? How is it possible that you are submitting a selftest that you didn't bother running?! I see you trimmed my earlier question: "Does this actually work?"

Have you checked spamfilters? With the kernels now, I cannot even test with the software bridge and selftests as the compile fails - probably due to changes in uapi headers compared to what the packages my system uses expects.

My spam filters are fine. I saw your emails where you basically said that you are too lazy to setup a VM to test your patches and that your time is more valuable than mine, which is why I should be testing them. Stop making your problems our problems. It's hardly the first time. If you are unable to test your patches, then invest the time in fixing your setup instead of submitting completely broken patches and making it our problem to test and fix them. I refuse to invest time in reviewing / testing / reworking your submissions as long as you insist on doing less than the bare minimum. Good luck

I have a VM to run these things that some have spent countless hours to develop with the right tools etc installed and set up. Fixing that system will take quite many hours for me, so I am asking for some simple assistance from someone who already has a system running supporting the newest kernel. Alternatively if there is an open sourced system available that would be great. As this patch-set is for the community and some companies that would like to use it and not for myself, I am asking for some help from the community with a task that when someone has the system in place should not take more than 15-20 minutes, maybe even less.

I'm sorry but this is absolutely the wrong way to go about this. Your setup's problems are yours to figure out and fix, if you are going to send *any* future patches make absolutely sure they build, run and work as intended. Please do not send any future patches without them being fully tested and, as Ido mentioned, cover at least the bare minimum for a submission. Thanks, Nik

Not true, it reveals that I forgot to put it in the patch, that's all. As I cannot run several of these tests because of memory constraints I link the file to a copy in a rw area where I modify the list and just run one of the subtests at a time. If I try to run the whole it always fails after a couple of sub-tests with an error. It seems to me that these scripts are quite memory consuming as they accumulate memory consuption in relation to what is loaded along the way. A major problem with my system.

A major problem with my system. I'm sorry for perhaps asking something entirely obvious, but have you tried: kernel-dir $ rsync -avr tools/testing/selftests/ root@$board:selftests/ board $ cd selftests/drivers/net/dsa/ board $ ./bridge_locked_port.sh lan0 lan1 lan2 lan3 ? This is how I always run them, and it worked fine with both Debian (where it's easy to add missing packages to the rootfs) or with a more embedded-oriented Buildroot.

I am not entirely clear of your idea. You need somehow to boot into a system with the patched net-next kernel or you have a virtual machine boot into a virtual OS. I guess it is the last option you refer to using Debian?

The memory problems are of course on the embedded target. In that case I think it would be a very good idea to do something to design the system better, so that it frees memory between the subtests. If all tests are always run on the bridge only, I think they don't make much sense as these patchsets are directed towards switchcores.

Debian, like many other Linux distributions, supports a wide variety of CPU architectures; it can be run on embedded systems just as well as on desktop PCs or VMs. I didn't say you have to use Debian, though, I just said I ran the selftests on a Debian-based rootfs and that it was easy to prepare the environment there. The Debian rootfs and the selftests were deployed to the target board with the DSA switch on it, in case that wasn't clear.

People like Martin Blumenstingl have managed to deploy and run the networking kselftests on OpenWRT, which typically runs on very resource-constrained embedded devices. https://lore.kernel.org/netdev/CAFBinCDX5XRyMyOd-+c_Zkn6dawtBpQ9DaPkA4FDC5agL-t8CA@mail.gmail.com/ https://lore.kernel.org/netdev/20220707135532.1783925-1-martin.blumenstingl@googlemail.com/ Considering that, you'll have to come with a much more concrete description of why the system should be "designed better" and "free memory between subtests" (what memory?!) before you could run it on your target system. Either that, or at least take into serious consideration the fact that you may be hung up on doing something which isn't necessary for the end goal. I simply have no clue what you're talking about. It's as if we're talking about completely different things. > If all tests are always run on the bridge only, I think they don't make > much sense as these patchsets are directed towards switchcores. Is this supposed to mean something, or is it just a random thought you had, that you believed it would be good to share with us? The tools/testing/selftests/net/forwarding/lib.sh central framework has the NETIF_TYPE and NETIF_CREATE variables, which indicate that by default, veth interfaces are created. When running a bridge selftest with veth as bridge ports, indeed software bridging should take place, and those selftests should work fine. In Linux, the software behavior represents a model for the offload behavior, since offloads are 100% transparent to the user most of the time. Below in lib.sh, there is a line which sources "$relative_path/forwarding.config", a file which can contain customizations of the default variables used by the framework. Even though it isn't strictly necessary to put the customized bash variables in a forwarding.config file, it is more convenient to do this than to specify them as environment variables. If you "cd tools/testing/selftests/drivers/net/dsa/", you will find precisely such a forwarding.config file there, which contains the line "NETIF_CREATE=no", which means that when you run the symlinked sub-group of forwarding tests relevant to DSA from this folder, the expectation is that the bridge ports are not veth interfaces created for the test, but rather, physical ports. So, by running the command I posted in the earlier email, you actually run it on the physical DSA user port interfaces, and it should pass there too. This is based on the equivalency principle between the software and the hardware data paths that I was talking about. If you're actively and repeatedly making an effort to work with your eyes closed, and then build strawmen around the fact that you don't see, then you're not going to get very friendly reactions from people, me included, who explain things to you that pertain to your due diligence. This is because these people know the things that they're explaining to you out of their own due diligence, and, as a result, are not easily fooled by your childish excuses.

Okay, that sounds like a good idea which I have not done before. I am seeing how I can install Debian in an Qemu or VMWare setup to be able to test that way. > This is based on the equivalency principle between the > software and the hardware data paths that I was talking about. > > If you're actively and repeatedly making an effort to work with your eyes > closed, and then build strawmen around the fact that you don't see, then > you're not going to get very friendly reactions from people, me included, > who explain things to you that pertain to your due diligence.

I am not coming with excuses here, and certainly not childish ones at that either. I am just pointing out that on my device the tests don't run well because of memory shortage and my reasoning why I think it is so. I will as long as the system is as it is with these selftests, just run single subtests at a time on target, but if I have new phy problems like the one you have seen I have had before, then testing on target becomes off limits.

Please open a dedicated communication channel (separate email thread on netdev@vger.kernel.org) with the appropriate maintainers for the PHY code that is failing for you in To:, and you will get the help that you need to resolve that and to be able to test on the target board.

The errors from the phy I saw in February. Maybe something was fixed in the meantime as I did not see the same warning and exception last I tried to run the newest kernel on target a little over a week ago.

Test FDB ageing of user entry created by bridge fdb replace ADDR dev <DEV> master dynamic Use LOW_AGEING_TIME variable in forwarding.config to set a low ageing time. Beware, DSA might not accept the ageing time you want. Check the age_time_coeff value for your driver. Signed-off-by: Hans J.
