It's possible to trigger memleak when the rule\nforwards packets from internal port and over tunnel, in the case that,\nfor example, CT 'new' state offload is allowed. As int_port object is\nassigned to the flow attribute of post_act rule, and its refcnt is\nincremented by mlx5e_tc_int_port_get(), but mlx5e_tc_int_port_put() is\nnot called, the refcnt is never decremented, then int_port is never\nfreed.\n\nThe kmemleak reports the following error:\nunreferenced object 0xffff888128204b80 (size 64):\n  comm \"handler20\", pid 50121, jiffies 4296973009 (age
