Description of problem:
[SR-IOV] - UI - Reflect 'No Filter' for passthrough vNIC profile that was created via rest api.

When creating/editing vNIC profile with a 'passthrough' property in the UI, it is immediately reflects as grayed out and 'No Filter' displayed.

But when creating/editing the same the vNIC profile with a 'passthrough' property via the rest api, the engine UI, display it as grayed out, but the 'vdsm-no-mac-spoofing' filter still visible, but it shouldn't.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create vNIC profile with 'passthrough' property via rest api

Actual results:
In the UI, the 'vdsm-no-mac-spoofing' filter still visible

Expected results:
If 'passthrough' checked we shouldn't see any network filter.

What happens when the VM is started? Does Engine request filter=vdsm-no-mac-spoofing ?

No, it is just a small ui bug. When VM starts it has no filter

Comment 3 Martin Mucha 2017-02-07 12:38:04 UTC
I don't believe it's small ui bug, I believe it's bigger backend bug. But I cannot tell, because there's no REST request you used or explaining description how you achieved this. Please next time provide that for simplifying flow.

What I assume you did: you took existing response returned via GET method, and used that to create new vNIC profile; you just removed ID and changed name in that xml. That would mean, that there's specified network_filter having name vdsm-no-mac-spoofing. Which is invalid request, because only "no network filter" can be specified. Am I right?

If I am, then there's incomplete validation phase in:
while UI is fine.

Can you confirm this?

Comment 4 Martin Mucha 2017-02-07 12:50:13 UTC
checking deeper, error (?) seems to be in REST layer.

If someone tries to add new vnic_profile using request, which lacks specified network_filter, default one is used, which currently happens to be vdsm-no-mac-spoofing.

So it seems (please correct me if I'm wrong), that you cannot create vnic_profile without network_filter via REST. You can do it only via UI.

If that's correct, I can easily fix that automatic use of default, but this will harm backward compatibility. Shall this be fixed?

To solve this specific bug, I can 'override' this logic and set no filter for each passthrough vnic_profile, but error mentioned above is probably worse.

This creates new vnic_profile without network filter.

Comment 6 Martin Mucha 2017-02-07 17:08:54 UTC
thanks for info about rest. Then it's about missing validations on bll layer. Seems to working after change, waiting for review.

Comment 7 Michael Burman 2017-04-27 08:05:55 UTC
No longer depend on bz 1445759 as it has WA if sending network filter as null.

Verified on - 4.1.2-0.1.el7
