Minutes/Updates
- Abhi Patil: Where is the L3AF project at currently? (high level overview)
- Orchestration across any eBPF platform in order to solve business problems
- L3AFd which runs on any host.
- Many eBPF programs - see wiki
- Create marketplace/repo of eBPF programs
- Simplify chaining of eBPF programs
- extend eBPF programs to Kubernetes
- Abhi P:
- Targeting DDOS programs
- Lead for DDOS initiative
- Peraton Labs and Georgia tech working on their project
- Karan: More details on the and use case yo move forward
General Topics (cover as needed)
- Use Cases
- eBPF program (soon to be open sourced)
- export records in IBPF format
- Enterprise number will be needed for this
Dave T: eBPF programs that will be put into marketplace
- L3AF could include signed programs
- samples
- Include other programs that are not signed by L3AF
- Is L3AF a framework for marketplace?
- Vicky B: Peel off marketplace from L3AF?
- Handled by different team that works with L3AF so it can support different project such as Polycube
- Dave T: Is the PEN for L3AF
- Karan: L3AF team is contributing programs and that is what the PEN is for.
- Jason: Agree with Dave, be careful with diluting L3AF
- Wallmart added programs should not be natively part of L3AF itself, but rather the Wallmart contribution to L3AF
- Dave T: Could you use a Wallmart PEN and contribute that to L3AF?
- Karan: Once the eBPF program is OSSed then we should use the Wallmart PEN and it should be under the LF after OSSing
- What kind of signing are we looking for?
- Verification that the eBPF programs are compatible with the L3AF platform
- For instance chaining.
- Need deeper dive.
- Verification that the eBPF programs are compatible with the L3AF platform
- What kind of signing are we looking for?
- Dave T: Whose PEN do you use. Whoever the signer is going to be?
- Karan: For now we don't have a clear bifurcation. It's just one L3AF.
- We should consider how to do this.
- Louis: IPfix program, is this a one time sign off or every time it is used?
- Dave T: Whenever there is a change to the program it must be resigned. Not a one time thing.
- PEN is a one time number. The signature changes with updates and revs.
- Karan: If someone wants to use IPfix and change the PEN they can do this. Not tying anyone to the existing PEN.
- Dave T: Then it would be a different program. Stars and other marketplace artifacet would be invalidated.
- Christopher L: Maintainer of the code should sign the code. The org that controls the commit bit.
- Raga P: planning to use PEN on IPfix to define custom fields. If there is no PEN then it would be an unknown field.
- Karan: Anyone could pass a PEN into these fields and change things. If you don't change things then you get the predefined custom fields.
- Term L3AF has been overloaded. L3AF team, platform, project, marketplace
- Dave T: L3AF is the foundation. The more we put programs into it the more it becomes the L3A instead of L3AF.
- Karan: If L3AF is the platform (L3AFd) how do we want to structure the remaining components?
- Keep L3AF marketplace as a separate project? Should we drop the L3AF branding on it?
- Vicky: Makes sense to have the marketplace be a separate thing with separate branding that is closely tied into L3AF.
- L3AF becomes the initial consumer of this, but we plan for other consumers.
- Louis: Consider breaking off separate projects under L3AF to ensure that the output of these is compatible with L3AF.
- Common in OSS world for Project Tech Leads to spin off other projects in this manner.
- Vicky: Makes a lot of sense to have things under L3AF initially. Perhaps move them later (eBPF Foundation).
- Jason: Small set of programs provided by L3AF itself and make sure they are compatible to help get things started in the begining.
- Vicky: This will help to get L3AF off the ground with a small set of programs that are useful and work.
- Jason: Yeah, these could be examples and building blocks that others can use.
- Karan: Definitely a good thing.
- Dave T: 3 catergories of stuff: core daemon, marketplace, programs
- Which one should be in different projects?
- Are they all under the L3AF?
- Where do the programs go?
- Is the marketplace part of the L3AF repo?
- Multiple marketplaces (Google, Apple, etc.). Is the marketplace part of the foundation?
- Does L3AF just contain samples? Leaning towards this one?
- Vicky: If marketplace is separate this is incredibly valuable because orgs can run their own marketplace. Should be a separate project.
- LJ: are any programs in the marketplace paid for items?
- DaveT: Yes, Vicky: leave door open
- LJ: Not sure it should be OSS?
- DaveT: Marketplace is not the programs. Paid programs can be distributed by on open source marketplace.
- Vicky: cannot confuse monitization strategy with the licensing strategy. For pay programs should not be excluded from an OSS project. It's the licensing.
- Brian M: This is good. Will take all these thoughts and work them into paper. Available this month(?), when we reconvene.
- Karan: Better to leave it open so that it is an attractive proposition for folks to contribute. We need to iterate on this a little more.
- Vicky: Brian's paper will help us to create a parallel working group to address this.
- Jason: Start them in the base and then move when available.
- Karan: For now we don't have a clear bifurcation. It's just one L3AF.
- Housekeeping: Next meeting is the 15th. Dec 22 and 29th are cancelled, reconvene on January 5th for Dev and testing forums
Action Items
Future Agenda Items
***** Minutes from previous call *****
- Polycube - Yunsong Lu representing
- Polycube is specific to Networking
- eBPF replace iptables → *this would be more crossplatform than current iptables designs
- eBPF Network Functions - 2010 PhD dissertation: https://ieeexplore.ieee.org/document/9340283
- Challenges - scale and rapid change in Linux kernel
- Kenny Paul: Where is Polycube used in production?
- No open information.
- Driven by developers in iovisor - not product tested.
- Apache license
- Presentation posted on L3AF Wiki page
- Yunsong:L 3AF code shares same goal as Polycube. What is the target market for L3AF? Long term goal?
- BrianM: L3AF - general purpose platform for orchestrating and running eBPF programs. Big driver is production features@ Wallmart. Kernel function marketplace, etc.
- DanielH: Can we switch from GPL to MIT licensing to make the code cross-platform with OSes like Windows and Apple?
