cilium/pwru v1.0.8

Release v1.0.8

on GitHub

We are pleased to release the 1.0.8 version of pwru.

The major changes include:

• pwru is now able to trace BPF helpers (#390). To enable it, set --filter-track-bpf-helpers. In addition, when it is set together with --output-caller, it can be used to roughly trace BPF tailcalls. For example:

# pwru --output-caller --output-tuple --filter-track-bpf-helpers
