[21.04 FEAT] Converged HiperSockets/Ethernet Interface - kernel

[bugproxy]

Support HiperSockets Converged Interface functionality, providing a converged interface that forms a single LAN based on HiperSockets (HS) and OSA/RoCE. Traffic for target hosts reachable via HS will use HS, all other traffic will be switched to OSA/RoCE.

Simplified network configuration via single network interface; ability to communicate with z/OS hosts using HiperSockets Layer 2.

[Frank Heimes (fheimes)]

What is the target kernel to get this new functionality upstream ? 5.4 or 5.5 ?
Setting to Incomplete for now ...

Need to be moved at, at least to 20.10. Will not make it with 20.04

[Frank Heimes (fheimes)]

Did this landed in 5.8 or does it need to be moved to 21.04 now?

Feature is an important one, even only the kernel part.
Once available, we will than ask for a feature freeze exception.

[Frank Heimes (fheimes)]

Since this is a kernel topic, there is still a little change to get it in, if it arrives prior to the kernel freeze - ideally by the end of September!
Once the kernel freeze is in effect, the entire release is in frozen too ...

git-commits are for kernel 5.10, currently in net-next

[Frank Heimes (fheimes)]

Commits landed in linux-next, but are (aot) just tagged with next-20200916, not with a kernel yet - aiu it's planned for integration with 5.10.

Feature will not make it for 20.10, moved to 21.04. Potential for request in the future getting this into 20.10 and 20.04..

This feature is available with kernel 5.10

[Frank Heimes (fheimes)]

Okay, thx - so pretty close (or already there?), since we are already at v5.10-rc2 - aot.

[Frank Heimes (fheimes)]

Since 5.10 landed in hirsute-proposed I'm updating this ticket to Fix Committed.

To exploit HSCI following build settings are required
CONFIG_BRIDGE and CONFIG_NET_SWITCHDEV

[Frank Heimes (fheimes)]

CONFIG_BRIDGE is enabled and in as module - so I think that's fine:
debian.master/config/annotations:CONFIG_BRIDGE policy<{'amd64': 'm', 'arm64': 'm', 'armhf': 'm', 'ppc64el': 'm', 's390x': 'm'}>

And CONFIG_NET_SWITCHDEV is enabled as well:
debian.master/config/config.common.ubuntu:CONFIG_NET_SWITCHDEV=y
debian.master/config/annotations:CONFIG_NET_SWITCHDEV policy<{'amd64': 'y', 'arm64': 'y', 'armhf': 'y', 'ppc64el': 'y', 's390x': 'y'}>
debian.master/config/annotations:CONFIG_NET_SWITCHDEV mark<ENFORCED> note<LP: #1865452, updated to 'y' for s390x starting with focal>

It was done based on LP 1865452.

I'd was that the kernel options look good.

[Frank Heimes (fheimes)]

Now that kernel 5.10 landed in hirsute's release pocket:
linux-generic | 5.10.0.14.16 | hirsute
this ticket is completed, hence the status is updated to 'Fix Released".
