We are pleased to release the 1.0.7 version of pwru.

The major changes include:

  • pwru is now able to trace XDP programs (#339). To enable it, use the --filter-trace-xdp flag. For example:

    pwru --filter-trace-xdp --output-tuple 'tcp and port 80 and host 100.64.0.101'

    <..> SKB CPU PROCESS TUPLE FUNC 0xffff97de3826d2c0 2 ~m-agent:2825426 100.64.0.101:80->172.20.0.2:45509(tcp) cil_xdp_entry(xdp) 0xffff97ddbf541840 2 ~m-agent:2825426 100.64.0.101:80->172.20.0.2:44879(tcp) cil_xdp_entry(xdp) 0xffff97df1390b000 3 ~m-agent:2825426 100.64.0.101:80->172.20.0.2:44879(tcp) cil_xdp_entry(xdp) * The MTU, which is printed when using --output-meta, can show modifications due to route MTU, XFRM policies, etc (#388). * The new --output-skb-shared-info can be used to show skb_shared_info (#364). * Improved tracking of SKBs when --filter-track-skb is used. For example, pwru is able to trace packets after they have been handled by XDP progs attached to veth (#384, [#391], [#397]).
