eBPF - Rethinking the Linux Kernel

QCon London International Software Development Conference returns on April 8-10, 2024. Level-up on 15 major software and leadership topics including; The Tech of FinTech, What's Next in GenAI and Large Language Models (LLMs), Performance Engineering, Architecture for the Age of AI, Innovations in Data Engineering and more.
Learn the emerging trends. Explore the use cases. Implement the best practices.

Thomas Graf talks about how companies like Facebook and Google use BPF to patch 0-day exploits, how BPF will change the way features are added to the kernel forever, and how BPF is introducing a new type of application deployment method for the Linux kernel.

The best eBPF talk I can find so far.

[@complexitytr9098]

Except the fact that many of us wont and cant use! Btw if someone wise browse by these comment(s). Feel free to drop book(s) name or something in case we/anyone wanna try learning about ebpf from scratch.

[@tomknud]

Intuitive and exhaustive rundown. Thanks

[@scetamit2555]

Amazing talk. Thanks.

[@danielfoehr9204]

Thanks, that was awesome!

[@chinmay8954]

Awesome talk, thanks !

[@ankk98]

Thank you

[@hgaliza]

Amazing talk!

[@oschvr]

Fantastic talk

[@deangur]

Very good lecture, I think you can fix/improve the sectioning of the video (it's not entirely aligned with the slides etc')

[@YogendraTamang]

Best talk.

[@tomknud]

Slide 19, user mode side car is missing.

[@tomknud]

Could a DDOS intender cause MAP expansion that eventually caused it or even crashed your kernels?

[@vadergrd]

if bpf is gonna be like npm i'm going to get the popcorn...

[@MARTIN-101]

what does this comment mean can you explain on this ? what does npm do ?

The change is not due to the programmability, it is a historical change in UI styling practice and hardware performance. Every program looked like grey blocks with poor colors in the 1990's to early 2000's, websites were only an example of ongoing practice. Then the industry learned that we could make aesthetic interfaces that people actually like to use, which began to bring the change in user interfaces. The client hardware started to allow more processing, after which we got programmability in the web.

[@ivan24zg]

Yeah today browser UIs are GPU-rendered, and CSS has turned into a Turing-complete monster. It's considered a bad practice to mix UI styling with JS, there is a clear separation between the two in modern JS frameworks. Programmability only affected interactiveness or the web pages, not their appearance.

[@JakobJenkov]

The idea itself sounds pretty cool! :-) ... not sure it should be JS... Web Assembly perhaps?

[@pajeetsingh]

you will use javascript and you will like it.

[@pajeetsingh]

That thumbnail gave me heart attack.

[@TheUser04460]

This is sound like: eBPF, eBPF everywhere…

[@tractatusviii7465]

Is BPF -- Redux for the OS? roughly :)

[@kortaffel]

Linux kernel bundle-of-sticks invented ring 2. much wow ...

[@unbekannter_Nutzer]

Can you at least name one single module, which had to be rewritten with every kernel release? Do you have a rough estimation, how many kernel releases there have been? Shameless, unbounded exaggerations smell like advertisement to me, an euphemism for lies.

[@122mlb]

Imagine what will happen to linux after Linus dies, it's going to be entirely re-written with "trendy" languages like Javascript/Python. What a disgrace.

[@dengan699]

why that would be? nonsense

[@misaelvalentin6154]

Way to miss the entire point of the talk.
