I'd probably drop the '(defined in filter.h, etc)' part, but otherwise I think it's fine. Thanks, Daniel

Judging from above error and that it works on Ubuntu 18.04, then your iproute2 version in CentOS-7 is simply too old aka lacking eBPF support. Try compiling one from recent Git [0] or some more recent

They only work for tc/BPF program types as they are based on sk_buff and not xdp_buff.

Does that happen via map update helper from kernel side in your prog? And the map iterate + delete, are there multiple threads walking it at the same time or just single one (just making sure ...)? Ok

Hi Dan, Thanks a lot for the report! Do you happen to have a reproducer? Are you running into this with concurrent i) updates, ii) deletes, iii) both or iv) while destroying the whole htab? If i-iii)

Depends on what rates you are targeting, you might want to check BPF raw tracepoints to reduce overhead given this would be in hot path. From f6ef56589374 ("Merge branch 'bpf-raw-tracepoints'") that t

There are some initial bits on BTF (mostly on the workflow for now) in the Cilium doc that can be found here: - http://cilium.readthedocs.io/en/latest/bpf/#llvm - http://cilium.readthedocs.io/en/lates

There's a tracepoint right before netdev_start_xmit() which is called trace_net_dev_start_xmit(). So you could combine sch_clsact egress with cls_bpf and a BPF prog on the tracepoint right before hand

Argh, I see the issue. Working on a fix after checking the syzkaller reports. Thanks for the report!

Applied to bpf-next, thanks Paul!

We should reuse check_helper_mem_access() here which covers all three cases from above already and simplifies the code a bit. Ditto. Thanks, Daniel
