We are pleased to release the 1.0.7 version of pwru.
The major changes include:
pwruis now able to trace XDP programs (#339). To enable it, use the--filter-trace-xdpflag. 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-infocan be used to showskb_shared_info(#364). - Improved tracking of SKBs when
--filter-track-skbis used. For example,pwruis able to trace packets after they have been handled by XDP progs attached to veth (#384, #391, #397).
