Hi ,
I am running the IPsec Security Gateway application ( at
http://dpdk.org/browse/dpdk/tree/examples/ipsec-secgw) on two VMs. It uses
AESNI crypto device.
Modified this application to add the Security Associations (SA) as ACL
rules like Security Policies (SP). I have added 100 entries of SP and SA. I
am also able to send the UDP traffic (one packet) in each of these tunnels.
But while sending 1 Gbs traffic (distributed through 100 tunnels) , it is
getting crashed . Here is the core dump
Core was generated by `./build/ipsec-secgw -l 0 -n 4 --pci-blacklist
0000:00:04.0 -- -p 0x3 --config=('.
Program terminated with signal SIGSEGV, Segmentation fault.

I am using ESP tunnel mode with AES encryption algorithm and SHA1
authentication algorithm . Here is the configuration to lunch the
application ./build/ipsec-secgw -l 0 -n 4 --pci-blacklist 0000:00:05.0 --
-p 0x3 --config="(0,0,0),(1,0,0)" -u 0x1 --cdev AESNI --ep0
There might be packets drop but it should not crash. Note that, with one
IPsec tunnel, I do not face this issue. Can anyone please suggest what
might be the issues behind this crash? Thank you in advance for your time
and support.
Please feel free to let me know if additional information is needed.
Regards,
Chinmaya

Hi,
I changed the classify algorithm to RTE_ACL_CLASSIFY_SCALAR via
rte_acl_set_ctx_classify() . Did not find the aforesaid crash issue. How
does DPDK decide the classify method for the given platform (default) at
startup ACL library? Furthermore how to know which classify method it has
chosen?
The VM where I am running the dpdk application supports SSE/ AVX
instructions set. They why it gets crashed during rte_acl_classify () with
1000 Mbps traffic and 100 IPsec tunnels.
Thank you in advance for support and time.

Hi Chinmaya,
What DPDK version are you using? Does it happen with latest DPDK 16.07?

My understanding is that SCALAR should be the default unless you change it.
That can be done by manually setting it or doing rte_acl_init();
