cilium/pwru v1.0.6

Release v1.0.6

on GitHub

We are pleased to release the 1.0.6 version of pwru.

The major changes include:

• pwru can track non-skb functions specified via --filter-non-skb-funcs (#355). For example, one can use pwru --filter-non-skb-funcs='xfrm_state_look_at,xfrm_state_lookup,xfrm_state_lookup_byaddr,xfrm_state_lookup_byspi' to enrich IPsec packet traces.
• Added tracing of skb's even if they were kfree-d (#354). By specifying --filter-track-skb-by-stackid, one can trace packets if they were freed, and then rebuilt (e.g., L2 bridge traffic).
• pwru is now able to output in JSON (#285). For example:

# pwru --output-tuple --output-meta --output-json 'host 1.1.1.1' | jq .
<..>
{
  "skb": "0xffff8fad947baf00",
  "cpu": 10,
  "process": "/usr/lib/firefox/firefox:1416291",
  "func": "kfree_skbmem",
  "iface": "0",
  "proto": 2048,
  "len": 94,
  "tuple": {
    "saddr": "1.1.1.1",
    "daddr": "192.168.1.159",
    "sport": 53,
    "dport": 34815,
    "proto": 17
  }
}

• (De)attaching kprobes got ~1.2 times faster (#277).
