[Qemu-devel] [PATCH] Unified Socket Transport
Posted by anton.ivanov@cambridgegreys.com 6 years, 9 months ago
From: Anton Ivanov <anton.ivanov@cambridgegreys.com>

1. Creates a common recvmmsg backend for socket transports
2. Migrates L2TPv3 to the new backend
3. Adds gre socket transport - a vm can attach directly to GRE
4. Adds raw socket transport - a vm can attach directly to an
Ethernet interface
5. Adds simplistic static VXLAN tunnel transport (no
control plane).
6. Sets up some of the infrastructure for future addition of
sendmmsg

Re: [Qemu-devel] [PATCH] Unified Socket Transport
Posted by Anton Ivanov 6 years, 9 months ago
Apologies, some bits of the second stage (sendmmsg) got in by mistake 
and broke the patch.

I will re-submit it later today including the proposed documentation, 
help and man page changes.

Re: [Qemu-devel] [PATCH] Unified Socket Transport
Posted by Anton Ivanov 6 years, 9 months ago
Hi Jason, hi list,

This is the first half (RX) of getting multi-message working for socket 
transports other than L2TPv3. I am looking at the second half (TX) as 
well as possibly moving the backend to something better than the legacy 
method(s).

As an example of where I would like this to go you can have a look at 
the UML patches which were posted yesterday:

http://marc.info/?l=user-mode-linux-devel&r=1&b=201707&w=2 - the 3 
patches dated 2017-07-17

The UML  implementation does the full set - RX/TX, DQL, BPF integration 
and scatter gather and I would like to reach a point where the QEMU 
implementation is feature and performance matched or better.

There are some instructions on setup as well as actual numbers at: 
http://foswiki.kot-begemot.co.uk/Main/EatYourOwnDogFood

A.

P.S.

This is an RFC - I would like some comments on how to organize multiple 
transports in the same driver, how it should look as far as qapi, etc. 
It should be possible to bring some of the existing code like half of 
net/socket.c under this umbrella as well.

A.

This list of features is a really strong sign that you should split
this patch up into a patch series with multiple commits, each commit
adding / changing a single feature. Especially keep refactoring of
existing code completely separate from adding of new features.

OK.

I can split it into series before next submission.
