Hi All, Thanks for dialing in to the meeting today. Here are my notes from the discussion.
Thanks, Brenden === Discussion === Alexei: - Discussion with some kernel devs regarding BPF memory model - some documentation to be done - (currently avoiding uapi enforcement on content of bpf program itself) - introduce standard header file for bpf programs to include - add read_once, write_once primitive - llvm will understand this - 64 bit jit must implement these instructions LSFMM will have a BPF track - CFP closes this Friday, send your proposals if you have them - Or send an email if you simply wish to attend Saeed: - LPC discussion followup - metadata parsing in hardware - way to notify/raise events userspace of new flow marks detected and trigger injection of tc rule? - use perf ring buffer, available in kernel samples/ Brendan: - bpftrace function tracing use case in java - needs couple fixes - uprobe to be able to attach heap locations instead of inode-only - tell c2 compiler to pause moving functions around - looking for ways to get past libc/libpthread backtrace walking (usually compiled without frame pointer) - hoping for Intel LBR support, but not available in many cloud VMs yet === Attendees === Brenden Blanco Andrii Nakryiko Dan Siemon Marco Leogrande Jesper Brouer Jerome Marchand Tom Stellard Jakub Kicinski Bjorn Topel Martin Lau Andy Gospodarek Paul Chaignon Jiong Wang Alexei Starovoitov Daniel Borkmann Saeed Quentin Monnet Mauricio Vasquez Matheus Marchini Joe Stringer Florian Brendan Gregg -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
