Brenden Blanco
 

Hi All,

Thanks for joining the call today after a short holiday hiatus. Below are my
notes from the call.

=== Discussion ===
Brenden
* Adopted new project kubectl-trace into github.com/iovisor from the author's
(@fntlnz) personal github
- Adds support for running bpftrace as a 'kubectl trace' command in a
kubernetes environment
- Presented at Kubecon 2018:
https://kccna18.sched.com/event/GrYw/ebpf-powered-distributed-kubernetes-performance-analysis-lorenzo-fontana-influxdata
- Please give it a spin and contribute/comment on
github.com/iovisor/kubectl-trace
* Nice work Lorenzo!

Yonghong
* funcinfo and line info merged BTF support merged into kernel
* clang debug info for bpf
- use -g from clang to generate such info that gets passed along to BTF
- some blocking issues to bring this feature into bcc
- btf info not being handled properly by dynamic linker
* bcc plan to release by end of the week to coincide with kernel release
* wip: add 128 bit int support

Brendan
* Compiler errors with linux 5.0-rc (asm goto)
* Working on documentation and packaging for bpftrace
- lots of small bugs to fix marching towards 1.0

Alexei
* Proposing dates and format for BPF/IO Visor specific technical miniconf in the
springtime
- March-May timeframe
- 2 days?

William
* Adding AF_XDP support to vSphere driver
