feat: implement MlxResetFW to reset the FW on VF changes #733

tobiasgiese · 2024-07-11T14:26:45Z

Todos:

implement new method to mstfwreset
add feature flag to opt-in/opt-out
add unit test
test it manually or via e2e test job (preferred)
add docs (will be added with docs: add feature gates to our readme #756)

Manual test shows that the implementation is working:

@zeeke @adrianchiris the GH Action ci-triggers change seems to work.
After a rebase and push no new comment has been added.
But after closing and reopening there is one. 👍🏻

SchSeba

in general looks good.

I only have an issue on what can be the case if one of the pciAddress for reset doesn't work and we return an error.

and if we reset the primary nic of the system we will not have an API connection to reconcile and we can leave the system in a bad state...

pkg/consts/constants.go

pkg/daemon/daemon.go

SchSeba · 2024-07-28T12:26:09Z

pkg/plugins/mellanox/mellanox_plugin.go

+		return err
+	}
+	if vars.MlxPluginFwReset {
+		return p.helpers.MlxResetFW(pciAddressesToReset)


return an error here can be problematic if we have multiple PCIAddress and one them them failed (for example the primary one)

If I understand you correctly your idea would be to introduce a errs variable to append the errors and return it at the end of the function, right?

tobiasgiese · 2024-07-29T08:19:10Z

and if we reset the primary nic of the system we will not have an API connection to reconcile and we can leave the system in a bad state...

Usually the reset of the fw should work. Also the code of the mstfwrest binary is tested. Additionally, we have a feature gate top opt-in, which means this is not enabled for the default usage. IMHO we should rely on the robustness of the reset.
Or have you already had experience with the reset and that's why concerns?

LGTM from my sided. just needs rebase
