Re: [ovs-dev] OVS-DPDK public meeting

[Kevin Traynor]

Hi All,

There has been a request to use the next OVS-DPDK meeting (Wed March 4th
@ 17:00 UTC, call details below) to present/discuss about Hw offload
capabilities and OVS integration with DPDK rte_flow API.

Perhaps some design discussion now can save time coding/reworking later.
Would request anyone with opinion on OVS Hw offload with DPDK rte_flow
API to attend.

Talking alone can be hard, so it would be good if anyone who has some
design ideas to put a few slides together to help communicate them on
the call.

thanks,
Kevin.

It wasn't discussed on the call (just fyi - it doesn't necessarily mean
anything except it may have been missed). You are better to ping for
review in reply to it's cover letter directly in this case.

Re: [ovs-dev] OVS-DPDK public meeting

[Kevin Traynor]

Next meeting Jan 8th 1700 UTC

November 27th minutes

Attendees: Aaron, David, Oz, Ilya, Johann, Simon, Roni, Ian, Thomas, Kevin.

- DPDK 19.11 Release
-- OVS validation complete to date
-- Ian presented tests performed with OVS and Intel NICs
-- Summary was sent to dpdk-dev
http://inbox.dpdk.org/dev/3b7e3b9b-117c-d23a-c8e3-43b94eb87...@intel.com/
-- Request from Ian for other device vendors test with dpdk-latest
branch, or when patch for master branch ready

-- Known Issues
--- Clear Memory Layout Flags
 Ilya submitted a fix for this
 There is some further discussion about the offload flags but it can
happen later in the context of dpdkr deprecation

--- Hotplug support for IGB_UIO
 The scheme for picking PA/VA mode in DPDK has evolved since 18.11
 The change in behavior (19.08):
https://git.dpdk.org/dpdk/commit?id=bbe29a9bd7ab6feab9a52051c32092a94ee886eb
 The selection process is explained here
http://doc.dpdk.org/guides/prog_guide/env_abstraction_layer.html#iova-mode-detection
 There can be a pattern now where adding an igb_uio bound device
with hotplug will require '--iova-mode=pa' eal param to work as before
 dpdk-extra ovsdb entry can be used for this with OVS
 General discussion was that vfio is preferred option and that
igb_uio is not suitable/supported in some environments
 Will need some addition documentation in OVS

- DPDK Stable Releases
-- 18.11.5
--- There is patches to update master/2.12/2.11 branches
--- 18.11.5 addresses
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-14818
--- OVS using dpdk vhost and untrusted guest should update
--- Updates for 17.11 on older branches will come later

- OVS Con 2019
-- Full house! hopefully live streaming will be available
-- Videos will be recorded

- rte_flow full hw offload through DPDK (Oz)
-- Patches are submitted for initial features
-- Some feedbacks from Ilya to address
-- Hoping they can be merged in time for 2.13
-- Later features can be vxlan, connection tracking etc.
-- Will present on this in ovs conf

dpdk-master branch
- Small discussion on effectiveness of it
- Some suggestions
-- Enable periodic travis build from it
-- More regular rebases from OVS master
-- Some earlier usage testing (e.g. with DPDK .08 release)

Next meeting date
- Was scheduled for 25th December
- Pushing to Jan 8th

===
GENERAL
===

- DPDK Stable Releases
-- 18.11.3
-- Still in validation, planning to release next week

- DPDK 19.11
-- Current Release date 8th Nov (but likely it will be later)
-- dpdk-latest branch in place and being use for early integration/feedback
-- Question if the branch should be updated weekly? (Ian)
-- dpdk-latest travis enablement - thanks David

- Conferences
-- DPDK Summit North America, Mountain View CA, November 12-13
-- OVS conf, Red Hat Westford (Boston area) December 10 and 11
https://mail.openvswitch.org/pipermail/ovs-announce/2019-September/000256.html



PERFORMANCE/FEATURES

- OVS 2.13 Planned Features
-- Detailed packet drop statistics per dpdk and vhostuser ports
-- Various patches to help with visibility and stats

-- DPDK 19.11 Update
--- as above

-- DPDK RFC 4115 egress policer (requires 19.11)
--- Eelco has submitted patches
--- perhaps they can be integrated on dpdk-latest branch?
 This seems to be an add on feature, so probably would not be
suitable for dpdk-latest, which is about keep compatibility with DPDK
project master branch

-- MSEG/TSO  (possibly requires 19.11)
--- Older patchset rebased
--- Still incurs overhead and code maintainability issues for OVS.
--- Flavio suggested alternative approach for vhost dequeue to help
reduce this, requires change in DPDK for 19.11 (Could lead to API/ABI
breakage)
--- Under discussion on DPDK ML
--- http://mails.dpdk.org/archives/dev/2019-October/145593.html /
http://inbox.dpdk.org/dev/20191001221935.12140-1-...@sysclose.org/

-- Miniflow bit dump utility
--- Builds upon DPCLS refactor from 2.12
--- Help to identify miniflow bits in use to allow sub table specialization.

Re: [ovs-dev] OVS-DPDK public meeting

[Kevin Traynor]

Next meeting April 15th 1600 UTC

Attendees: Aaron, Alejandro, David, Fouad, Flavio, Ariel, Pieter, Mark,
Ian, Scott, Kevin.

===
GENERAL
===

- UNH lab testing (Aaron)
-- Integrating ovs_perf test scripts
-- Testing dpdk-latest OVS branch and dpdk master + patches from dpdk-dev
-- Would prefer a stable OVS base to avoid multiple moving targets
-- Dashboard https://lab.dpdk.org/results/dashboard/
-- Results mailing list https://mails.dpdk.org/listinfo/test-report

- DPDK stable releases
- DPDK 18.11.1 (OVS 2.11, OVS Master)
- Recently available, validated.
- DPDK 17.11.5 (OVS 2.10, OVS 2.9)
- Available but unit test failures flagged in DPDK validation.
- 17.11.6 will be released soon, so might be better to wait and
validate with it
- DPDK 16.11.9 (OVS 2.7)
- Final release for 16.11, 2 year support cycle ended.
- Probably worth it? as it's the last one

- DPDK 19.05 release
- dpdk-latest branch patched to compile with DPDK master (Kudos Ophir)
- dpdk-latest branch process
- if this is to be used to detect regressions with DPDK patches in
UNH, then it should not be updated much. However, then it loses some
effectiveness that the latest OVS is functional with the latest dpdk.
Maybe there is need for 2 branches with different purposes. Ian to send
a mail to discuss.

- Spring cleaning
- Deprecated features
- General question about deprecation and time frames.
- vhostuser
-- Not causing a maintenance burden as it's mostly shared code with
vhostuserclient
-- Aware of some cases where users want to upgrade from 2.6 -> newer
release but don't want to switch to vhostuserclient at upgrade time as
it's an additional risk.

- Experimental Features
- vhost zero copy
- SMC
- HWOL
- Experimental Tag process?
-  Should there be a set path to removing experimental tag for each
feature, even if that is different based on the type of feature.



PERFORMANCE/FEATURES

- Features Targeting OVS 2.12
- HWOL vport offloads
- DPCLS function pointers + scalar optimizations
- RFC4115 Egress policer
-- the required DPDK bits are not available in DPDK 18.11

Johann, Ian, Kevin.

===
GENERAL
===
- OVS 2.11 Release

http://docs.openvswitch.org/en/latest/internals/release-process/?highlight=release#release-scheduling

- DPDK Stable Releases
-- 18.11.1-RC1 in about a week
-- Considering validation times, 18.11.1 won't be ready for OVS 2.11
-- Next 17.11.5 release is waiting validation
-- Ian said may be able to do some RC testing with OVS test setup

- OVS CI Status
-- Aaron has some NICs sent by vendors ready for this
-- Servers in UNH, but they will be changed shortly
-- There is a regular call about the DPDK Lab
-- Next meeting is next Tuesday 12th Feb. Details in [1].


PERFORMANCE/FEATURES

- DPDK 18.11 Hugepage Memory limits
-- Patched added and backported to 2.11, to add the socket-limit by
default and so keep the existing default behavior

- Unifying DPDK EAL Arguments
-- Discussion on ML about this proposal to remove the some of the
specific DB entries for DPDK EAL args
-- Would be a user visible change, so good if people can to look at the RFC

- MESON packaging and Build
-- RH using make for DPDK
-- Aaron will try out pkg-config patch


Bugs

- dpif-netdev:fix reload pmd's dead lock
-- Now resolved as being issue with user local code changes

This issue got introduced due to commit 293c0c4b9. This change will try 
to map the huge page memory we need starting at 0x1. If it fails 
the hint, it will retry increasing the address, until it gets the 
mapping at the requested address. This to minimise the chance to map it 
outside the HWs DMA address space.


However just before doing this DPDK also mmaps each individual huge page 
in the system. It starts low, but it will collide with the 0x1 
address.


When this happens there a quite some retries until we find the mmaps we 
want. So the more memory in huge pages, the more time it takes. It 
depends on the number of huge pages in the system, not the memory 
configured for OVS.


FYI this mapping on a 32G huge page system:

Re: [ovs-dev] OVS-DPDK public meeting

[Kevin Traynor]

Next meeting: 21st August 16:00 UTC.

Minutes of meeting 8th August 2018.
Attendees: Eelco, Thomas, Matteo, Ian, Ophir, Johann, Yipeng, Tiago,
Simon, Kevin.

===
GENERAL
===
- OVS 2.10
-- No info on anything that would make 2.10 slip
-- No news is good news :-)

- Updates to OVS to use latest DPDK
-- DPDK 18.11 will be an LTS and will be required for hardware offload
-- Suggestion to move OVS master to use DPDK 18.08 interim step
-- Would give time to flush out any integration bugs using later DPDK
releases before DPDK 18.11 is available

- Branches for future work
-- Request from Ophir to have a branch for hardware offload as it will
require significant effort. Ian will talk with Ben about it where it
should be.
-- Suggestion for the future to have a new branch working with latest
DPDK (e.g. 19.02/19.05 etc)to catch and feedback any integration issues.


PERFORMANCE/FEATURES


- Outstanding bug fixes:
-- dpif-netdev: Avoid reordering of packets in a batch with same megaflow.
-- This has been reported in the wild and would need to go on branches.
Question about whether this should try to be included for 2.10 release
or not. But anyway patch is not merged in master yet.

- Tiago has posted an RFC of TSO

- Move OVS 2.7 to use 16.11.7
-- Any reason not to? No one had any


HARDWARE OFFLOAD

- Ophir gave us an update and it seems like there has been good progress
and collaboration between vendors.
- There would need to be some new functionality wrt adding several ports
at once but it wouldn't break backward compatibility.

+1. Also, consider that it's not just a few bug fixes - it's hundreds.

The OVS branches are typically bug fix only, so what seems ok now,
doesn't look as nice in 3 months time when there are no more DPDK bug
fixes and something is not working. Take that recent DPDK CVE as an
example (but it would be the same for any DPDK bug)

OVS 2.6 uses DPDK 16.07 - no CVE fix
OVS 2.7 uses DPDK 16.11 LTS - CVE fix
OVS 2.8 uses DPDK 17.05 - no CVE fix
OVS 2.9 uses DPDK 17.11 LTS - CVE fix

I think it's best to be sticky to LTS and only consider moving if
there's a new compelling ready to go feature, or there's support for a
new device that people need - and has been tested :-)

In my eyes that would the only way to satisfy both user's needs: Keep default 
support for the associated DPDK LTS release and add optional support for 
bleeding edge DPDK versions. The downside of this is that it will likely 
clutter the OVS code with conditional compiler directives to handle the DPDK 
API/ABI incompatibilities. Plus, someone must also clean these up at a later 
stage when they are no longer needed.

Today, OVS developers that really need the latest DPDK typically fork/branch 
OVS locally and maintain their fork until OVS master switches to the required 
DPDK version. That model doesn't burden the community with the problem.

I'd like to argue with you, but then can't.
We all know that velocity<->stability is a tradeoff, and being mostly
driven by bleeding edge HW DPDK chose a different focus than most others.
We are back at my statement of the two kinds of people now :-)

/me looks left and right, then dons flame retardant pants

One of the bigger community hurdles is to impress upon DPDK developers
the importance of ABI/API stability.  Without this, then applications
which consume DPDK (Open vSwitch, MoonGen, trex, etc) will always be
version locked.  Even if the linker/loader doesn't immediately barf,
there's no guarantee that things aren't broken.

OTOH, by sticking with an LTS, we can 'guarantee' (well, with as much
certainty as anything in life) that we are able to upgrade that version
of the library without blowing up the world.

If you can get a better ABI/API adherence in DPDK, then I'm all for it
(I'd love if we could just drop version numbers altogether, as it would
be the most 'natural' for developers and users).

There are always the two big groups of users.
- Those that want max stability for a huge Production setup (which would
follow the pick LTS argument)
- And those that want/need the very latest HW support and features (which
would always prefer the latest version)

I had no single critical feature in mind for 18.05, but especially your
argument of "the largest DPDK release to date with a lot of code being
introduced" makes it interesting for the second group.
Actually I think there are also plenty of new devices which are not
supported at all before 18.02/18.05.

So far my DPDK upgrade policy was "the last DPDK available which has at
least one point release AND works with OVS".
If OpenVswitch really changed to only support to each DPDK LTS version,
then I might have to follow that.
I must admit I already had the same thought to only pick .11 stable
versions, so I'm not totally opposed if that is the way it is preferred for
Openvswitch.

But if we can make this a toleration (saying it works with 17.11 AND newer
18.05) then this would be a great contrib to OVS and IMHO be warranted.
If the latter would work it could be great to spot issues early on instead
of having a super-big jump from 17.11 to 18.11 in one shot.
But if you have to kill support fot 17.11 to let it work with 18.05, then
better not.

Interested what other opinions on this are.

Thanks for raising Christian,

It wouldn't be a clean transition from 17.11 to 18.05 as there are a few 
changes (as you have spotted). AFAIK there are also changes to the meter 
library to provision profiles, this would have to be addressed in OVS also.

I was planning to if the community agreed it was warranted.

However the general feeling expressed at the past few community calls is that 
the next move should be to DPDK 18.11 LTS and I tend to agree with this.

The main advantage of this is the DPDK LTS lifecycle provides bug fixes for 
DPDK for 2 years from release. Moving to a non DPDK LTS becomes a pain as 
critical bug fixes will not be backported on the DPDK side so are not addressed 
in OVS with DPDK either, we've seen this with some of the CVE fixes for vhost 
quite recently.

18.05 is also the largest DPDK release to date with a lot of code being 
introduced in the later RC stages which IMO increases the risk rather than the 
gain of moving to it.

However I'm open to discussing if a move to 18.05 is warranted, are there any 
critical features or usecases it enables that you had in mind?

Thanks
Ian

Hi,
I wanted to ask if anyone is already looking at DPDK 18.05 toleration or
even exploitation.

I just tried to built recent OVS against it and (there might be more) at
least dpdk change
  cd8c7c7c ethdev: replace bus specific struct with generic dev

breaks OVS due to code in lib/netdev-dpdk.c accessing that with an error
like:

../lib/netdev-dpdk.c:2800:17: error: ‘struct rte_eth_dev_info’ has no
member named ‘pci_dev’
 if (dev_info.pci_dev) {

I re-built an old 2.9.0, but saw that even on master the code still is
as-is, so I assume OVS master and coming 2.9.3 are affected as well.

Usually a few days after DPDK there were patches for OVS, but so far I
found nothing on the mailing list.
So I wanted to ask if there is someone already (planning to) work on these?

HARDWARE OFFLOAD

- Classification offload
-- Looking to add it in pull-request+1
-- Any more comments? Speak now, or send patches later :-)

- Full offload
-- APIs are added in DPDK 18.05, but it will be at least DPDK 18.08
before the PMDs have an implementation.

-- DPDK 16.11.6 targeted for May 19, 2018

- DPDK 18.05
-- RC0 available
-- Intel completed minor testing (compilation), will require changes for
rte meter profile (egress/ingress policer).
-- Feedback from community on the need for 18.05?
-- DPDK 18.05 proposed features: http://dpdk.org/dev/roadmap
-- No feedback on call about any compelling feature worthy of losing
DPDK LTS support atm

- OVS 2.10 Roadmap Review
- Ian talked about the items Intel are working on
https://docs.google.com/spreadsheets/d/1FilGq46vQePFKoehADWWsDvDCZSNsMU7PrpPr3EM3lU/edit


PERFORMANCE/FEATURES

- Detailed PMD Metrics
-- V10 reviewed, minor changes requested. Nearing commit stage.
-- Awaiting v11 from Jan.

- LSC interrupt mode
-- Queries raised on v6 regarding use now that DPDK has introduced fixes
admin wait times in i40e devices related to the issue
http://dpdk.org/ml/archives/dev/2018-March/092156.html
-- Still seen as useful and worth backporting to 2.8, 2.7.
-- Minor changes requested for v6.

- OVS DPDK documentation rework
-- Patchset submitted to re-organize OVS DPDK documentation into
separate topics.
https://mail.openvswitch.org/pipermail/ovs-dev/2018-February/344372.html

-- V2: https://mail.openvswitch.org/pipermail/ovs-dev/2018-April/345672.html
-- Sits in between EMC and DPCLS
-- EMC is still fastest, but DP Cache good when > 4K-8K flows and EMC is
ineffective
-- Useful up to about 1M flows, then some performance degradation.


HARDWARE OFFLOAD

- V8 submitted by Shahaf Shuler and Finn Christensen.
https://mail.openvswitch.org/pipermail/ovs-dev/2018-March/345500.html

[Sugesh] After the discussion with intel DPDK team, we expect basic DPDK
full acceleration apis  will be ready in DPDK-18.05 and we can leverage  them 
in OVS
for the initial release. This means we can have some early enablement of 
OVS-DPDK full acceleration
by 2.10

So lets plan full acceleration enablement for

OVS 2.9 Release

Outstanding bug fixes
- rhel: Fix support for root user using DPDK.

-- Led to further discussion about mempool in OVS 2.9

DPDK mempool model
- Discussed some of the issues with per port mempool
- Discussed compatibility issues for an OVS 2.9 and that some users may
not be able to use OVS 2.9 until there is a new mempool scheme
- Possibility of a revert of per port mempool discussed - Ian said he
would send a link and RFC for review
- Jan, Kevin, Flavio spoke/wrote in favour of a revert for OVS 2.9. No
one spoke against it on the call.

Hwol
- Looks to be too late for classification offload patches for OVS 2.9
- Ian had intended to review, but mempool issue took time. Jan said he
would like to review also
- Simon asked if anything blocking them from 2.10 - nothing.

Feel free to add/correct.

thanks,
Kevin.

GENERAL
===
OVS 2.9 Release
- Deadline Dates
-- Deadline passed for new feature proposals
-- Plan to branch for OVS 2.9 on 15th Jan
-- Would like to minimize new feature commits into OVS 2.9 branch but
some flexibility
- Outstanding Features/Patches to be merged
-- Discussion on some relevant patches (below in perf/feat)

Spectre/Meltdown
- Request for people to test with fixes and report any perf regressions

Suggestion by Ian to make OVS-DPDK meeting weekly for next few weeks, to
use for OVS 2.9 dicsussion prior to the release
- Set up for same time, same links weekly for next few weeks
- Next one 17th Jan


PERFORMANCE/FEATURES


PMD debug/Time based Tx batching
- Didn't discuss these much as Jan and Ilya weren't on call

MTU segfault/ Bug fix.
-- Ian gave us a "high level" explanation
-- https://mail.openvswitch.org/pipermail/ovs-dev/2018-January/342858.html

OVS DPDK Unit Tests
-- Marcin submitted here
https://mail.openvswitch.org/pipermail/ovs-dev/2018-January/342523.html
-- Aaron also has some ideas for UT's also

Rxq-pmd stats
-- Kevin has removed dependencies and simplified
-- https://mail.openvswitch.org/pipermail/ovs-dev/2018-January/342999.html

Ports sharing PCI id
-- To allow devices that have ports sharing a PCI id to be used fully
-- Doesn't seem to be any objections to DPDK devargs syntax - next step
to write documentation patch for it.
-- https://mail.openvswitch.org/pipermail/ovs-dev/2018-January/342865.html



HARDWARE OFFLOAD

Classification offload
- This appears to be almost ready for merging
- View is that while this will continue to exist, full offload will
eventually be preferred so there needs to be some flexibility to allow
changes for full offload later
- No objections to proposal that it is EXPERIMENTAL due to above
- Sugesh will set up a separate meeting to discuss the design for full
offload

-- Gave summary of LTS and API/ABI stability discussions at DPDK userspace
-- Some discussion about having OVS LTS use DPDK LTS - seems like good idea
-- Likely to be a yearly DPDK LTS
-- The rate of new features in DPDK means that there are breaks in
API/ABI. Nothing to indicate that this will change over the short term.
-- Thomas would like to see more participation in helping review to get
new API's right
-- John McN sent summary of discussions here
http://dpdk.org/ml/archives/dev/2017-October/077935.html

- Output batching
https://mail.openvswitch.org/pipermail/ovs-dev/2017-October/339467.html
-- We missed discussing this?


HARDWARE OFFLOAD

- rte_flow offload
-- Progressing on the ML
-- Currently offloading matching, would like to move to full offload in
future
-- DPDK rte_flow API seems sufficient for now. Longer term would be nice
to add more actions.
