We are pleased to announce that the BPF microconference[0] has been
accepted into the 2019 Linux Plumbers Conference[1]! Last year's BPF
microconference[2] was such a success that it will be held again
this year.

BPF[3] along with its just-in-time (JIT) compiler inside the Linux
kernel allows for versatile programmability of the kernel and plays
a major role in networking (XDP[4], tc[5] BPF, etc.), tracing
(kprobes[6], uprobes[7], tracepoints[8]) and security (seccomp[9],
landlock[10]) subsystems.

Since last year's Plumbers Conference, many of the discussed
improvements have been tackled and found their way into the Linux
kernel such as significant steps towards allowing for a compile-once
paradigm with the help of BTF and global data support as well as
considerable verifier scalability improvements to name a few. The
topics proposed for this year's event include:

 - libbpf, loader unification
 - Standardized BPF ELF format
 - Multi-object semantics and linker-style logic for BPF loaders
 - Verifier scalability work towards 1 million instructions
 - Sleepable BPF programs
 - BPF loop support
 - Indirect calls in BPF
 - Unprivileged BPF
 - BPF type format (BTF)
 - BPF timers
 - bpftool
 - LLVM BPF backend, JITs and BPF offloading
 - and more

Come join us and participate in the decision making of one of the most
cutting edge advancements in the Linux kernel!

See here[11] for a detailed preview of the proposed and accepted topics.
Please feel free to submit your discussion proposals to Alexei or
Daniel: lpc-bpf at vger.kernel.org

LPC will be held at the Corinthia Hotel, Lisbon, Portugal, 9-11
September 2019, colocated with the Linux Kernel Summit.

We hope to see you there!
