Hi all, Thanks for joining the call today. As usual, here are my notes from the discussion.
=== Discussion === Alexei: LSF/MM - BPF track * overall went quite well * planning BPF conference for next year * notes @ http://vger.kernel.org/bpfconf2019.html Yonghong: * Compiler work to support compile-once-run-anywhere * LLVM code review fabricator - search for yonghong to find patch * Send signal bpf helper RFC1 has some issues * trying instead to send to current, even if in interrupt context * Other updates: some work for map of maps support in bcc John: * Some progress on bounded loop * Performing arithmetic on induction variables in one pass through loop * Many loops have simple enough induction variable strides to satisfy this simple algorithm * other sockmap and ktls fixes * release/acquire socket lock issue in ktls * fuzzing fixes Jiong: * 32 bit patchset work continues * Currently determining how to test * Setting up arm 32 bit qemu environment has issues * Cross-compiling kernel + selftest suite * Some offers to test on 32 bit x86 Brendan: * BPF book is currently being reviewed * If someone on the call would like to contribute reviews, reach out to Brendan * bpftrace syntax to be finalized * some compiler hints would be nice to pass __user pointer annotation to the scripts, otherwise explicit wrapper is necessary * necessary only for mixed mode tools Joe: * socket_assign helper for proxying support in bpf * tproxy working for tcp, working on udp * skc_lookup[_tcp] helper needed? * some leakiness in the socket api/bpf abstraction, needs to be worked out Daniel: * Out of bounds fix * cgroups hooks for sendmsg * breaks for DNS * add recvmsg hooks for reverse path, to avoid lookup failure * some minor fixes for connected (tcp) case Andrii: * Improving libbpf for BTF (and in prior kernels) * BTF to C converter * next: using BTF to define bpf maps === Attendees === Alexei Starovoitov Andrii Nakryiko Augusto Caringi Dan Siemon Jesper Brouer Richard Elling Brenden Blanco Jiong Yonghong Song Andy Gospodarek Daniel Borkmann Jakub Kicinski Brendan Gregg John Fastabend Mauricio Vasquez Paul Chaignon Joe Stringer -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
