[asood-rh]

I think there is enough LGTM's here for me to add the risk-assessed label and get this in. I was hoping to not do this during shift week to avoid any potential issues but based on what @sdodson said above, we can get it in instead of waiting till next week to land the OVS bumps.

Risk-assessment for backport:

1. I see a slight risk for backport because this is the first PR where we are bringing in the backport of the Kube Rebase from 4.19 to 4.18. Thanks to ART team for taking care of the golan version. However despite this risk CI is green and that's all the signal we can get. @jluhrsen if possible please keep an eye on the next two payloads that release after this lands to ensure they are green.
2. Besides kube rebase I guess we are bumping swan to 5.2 here? @pperiyasamy whatever is the unpinned version in 4.18 which means the scale regression will be introduced in 4.18 as well? Any other IPSEC bugs?
3. OVN bump as well but fdp lane was run and is green - again that's the best signal we can get
4. Bringing in two new features: localnet API and BGP which are turned off in 4.18 actually and have 0 tests from QE side on 4.18 FYI @asood-rh : localnet is not behind a feature gate though BGP is - please do some regression tests for localnet feature or perhaps copy your automation tests to also run on 4.18 post this change - though its not officially supported on front facing docs - we just need to make sure we don't have regressions

Regardless the CI is fully green on all required jobs and that's the best we can do, acknowledging the above risks, adding the label since we need to get all the bug fixes landed into 4.18.

@tssurya The localnet API ( CUDN API with localnet support, UDN does not support Localnet in 4.19 ) is blocked on 4.18 so we do not need to run 4.19 tests against it. If we plan to support Localnet in 4.18 we should have an epic to track it.

4.18 just had a localnet on default network exposed through NAD.

The user gets a message for it as unsupported value in 4.18 for CUDN.

The ClusterUserDefinedNetwork "sec-localnet-net" is invalid: 
* spec.network.topology: Unsupported value: "Localnet": supported values: "Layer2", "Layer3"
* : Invalid value: "null": some validation rules were not checked because the object was invalid; correct the existing errors to complete validatio

As for BGP regression is underway and will update the results.

I think there is enough LGTM's here for me to add the risk-assessed label and get this in. I was hoping to not do this during shift week to avoid any potential issues but based on what @sdodson said above, we can get it in instead of waiting till next week to land the OVS bumps.

Risk-assessment for backport:

1. I see a slight risk for backport because this is the first PR where we are bringing in the backport of the Kube Rebase from 4.19 to 4.18. Thanks to ART team for taking care of the golan version. However despite this risk CI is green and that's all the signal we can get. @jluhrsen if possible please keep an eye on the next two payloads that release after this lands to ensure they are green.
2. Besides kube rebase I guess we are bumping swan to 5.2 here? @pperiyasamy whatever is the unpinned version in 4.18 which means the scale regression will be introduced in 4.18 as well? Any other IPSEC bugs?
3. OVN bump as well but fdp lane was run and is green - again that's the best signal we can get
4. Bringing in two new features: localnet API and BGP which are turned off in 4.18 actually and have 0 tests from QE side on 4.18 FYI @asood-rh : localnet is not behind a feature gate though BGP is - please do some regression tests for localnet feature or perhaps copy your automation tests to also run on 4.18 post this change - though its not officially supported on front facing docs - we just need to make sure we don't have regressions

Regardless the CI is fully green on all required jobs and that's the best we can do, acknowledging the above risks, adding the label since we need to get all the bug fixes landed into 4.18.

@tssurya The localnet API ( CUDN API with localnet support, UDN does not support Localnet in 4.19 ) is blocked on 4.18 so we do not need to run 4.19 tests against it. If we plan to support Localnet in 4.18 we should have an epic to track it.

4.18 just had a localnet on default network exposed through NAD.

The user gets a message for it as unsupported value in 4.18 for CUDN.

The ClusterUserDefinedNetwork "sec-localnet-net" is invalid: 
* spec.network.topology: Unsupported value: "Localnet": supported values: "Layer2", "Layer3"
* : Invalid value: "null": some validation rules were not checked because the object was invalid; correct the existing errors to complete validatio

As for BGP regression is underway and will update the results.

Oh that's weird.. I swear I saw the API for local net support commit here from @ormergi ....

Ohhhh hold on.. the CNO side of yaml change never happened :) so that's why it's off.. its good in some sense haha
