BPF Updates 01

BPF Updates 01

[Alexander Alemayhu]

Hei Everyone,

I have started writing a short weekly roundup on the various BPF related
activity. The first issue 
https://www.cilium.io/blog/2017/5/2/bpf-updates-01-2017-05-02

The main motivation is to have something similar to LLVM Weekly[0] and This
week in Swift[1]. Hopefully useful for people hungry after more BPF related
content without wanting to subscribe to netdev or filtering through lkml.

The second issue is already in the works and will be sent to the list
sometime next week. If you have any feedback, that would very
appreciated.

Thanks.

Mit freundlichen Grüßen

This is great thanks for sharing.

I also want to point to this cilium blogpost:
 https://www.cilium.io/blog/2017/4/24/launch-of-bpf-xdp-documentation

eBPF is sort of the XDP programming language, and if you want to learn
the details of the BPF Architecture and know more about the instruction
set, follow the blogpost link to: http://docs.cilium.io/en/latest/bpf/

I believe people subscribed to this list is more interested in having a
toolchain like LLVM that allow us to write (restricted) C-code and
generate the eBPF assembler for us. Luckily the same document describes
how this works and why e.g. inlining is required, here:
