[ovs-dev] netdev-dummy memory leak: ofproto-dpif - sFlow packet sampling - tunnel set

[William Tu]

Hi,

I spent some time fixing this memory leak but couldn't get it right. Please
give me some advise how to fix it. Thank you.

Testcase:
898: ofproto-dpif.at:5172 ofproto-dpif - sFlow packet sampling - tunnel set
Call stacks:
  malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
  xmalloc (util.c:112)
  dp_packet_new (dp-packet.c:131)
  eth_from_packet_or_flow (netdev-dummy.c:1308)
  netdev_dummy_receive (netdev-dummy.c:1370)
  process_command (unixctl.c:297)
  run_connection (unixctl.c:331)
  unixctl_server_run (unixctl.c:384)
  main (ovs-vswitchd.c:121)

Thank you
William
