LISA21 - BPF Internals
Having to deal with bpf_printk() recently for some fancier debug output I realized there are a bunch of interesting aspects worth sharing, especially taking into account various kernel versions. This resulted in nakryiko.com/posts/bpf-tips… Hope it will be helpful to someone.

New kernel post! This time: /proc/*/mem and how it writes to unwritable mem. Key takeaway: By walking page tables in software, the kernel can access userspace mem without directly dereferencing pointers it gets from userspace. (No WP/SMAP bits involved). offlinemark.com/2021/05/12/an-…

I wrote an article about BPF and Linux perf 🎉 The article includes step-by-step debugging with flame graphs, and many nitty-gritty details that tie themselves together at the end (i promise!). #bpf #ebpf #linux doordash.engineering/2021/04/01/exa…
Prediction: exokernels era begins thanks to eBPF Interesting use of eBPF to reduce the access latency to NVMe (half of the overhead is due to the kernel storage path usually) 👇 arxiv.org/pdf/2102.12922…
Meet bperf: Sharing hardware PMCs with BPF. git.kernel.org/acme/c/7fac83a… 2nd use of BPF skels in perf, first one was to use BPF in perf to count events in BPF programs. Again, thanks to @SongLiuBraving! #perf_tools #bpf #linux
gRPC server in kernel with eBPF; three times faster than go, two than Rust. Implemented minimum features just for benchmarking. eBPF (sockhash) gives hook for data arriving on TCP/UDP sockets, useful to implement server software? Or too restrictive? github.com/fujita/greeter…

Thanks @anakryiko for helping me improve this article！
In a previous post, our #TiDB engineer @ethercflow shared why we switched from bcc-tools to #libbpf-tools. This time, he introduces some tips & tricks for writing libbpf-tools. hubs.ly/H0Cy7hP0 We hope this post can help you write efficient and correct #BPF programs.
For anyone thinking of doing a eBPF observability/tracing startup: this costs companies ~$52, has >100 open source tools, and was written by an expert with >15 yrs tracing experience & help from other BPF experts brendangregg.com/bpf-performanc…
