QUESTION
I am new to DPDK, currently testing IP reassemble API and I am having difficulties. Below is the C++ code which I wrote to test the IP reassemble. I took the reference from the examples list provided from dpdk itself. dpdk version which I am using is 20.08 in debian machine. dpdk user guide mentions the API works on src add, dst add and packet ID, even though all three data are proper still the API returns NULL. Any kind of help will be much appreciated. Thanks in advance.
...ANSWER
Answered 2020-Oct-22 at 09:27DPDK API rte_ipv4_frag_reassemble_packet
returns NULL in 2 ocassion
- an error occurred
- not all fragments of the packet are collected yet
Based on the code and logs shared it looks like you are
- sending the last fragment multiple times.
- setting time out as
cur_tsc
Note:
- the easiest way to test your packet is run it against
ip_reassembly
example and cross check the variance. if (mo == NULL)
it only means not sufficient fragments are received.
[edit-1] Hence I request to model your code as dpdk example ip_reassembly since assuming rte_ipv4_frag_reassemble_packet
returning NULL is not always a failure.
[edit-2] cleaning up the code and adding missing libraries I am able to get this working with right set of fragment packets
