Re: [dpdk-users] Using l2fwd-crypto sample app

["Das, Surajit" <Surajit.Das@commscope.com>]

Hi,

I found why I could not get l2fwd-crypto to run.

The steps to get it to work is as below:

wget https://www.nasm.us/pub/nasm/releasebuilds/2.15.05/nasm-2.15.05.tar.gz
tar -xvf nasm-2.15.05.tar.gz
cd nasm-2.15.05
./configure
make
make install

cd
git clone https://github.com/intel/intel-ipsec-mb.git
cd intel-ipsec-mb
make
make install
export AESNI_MULTI_BUFFER_LIB_PATH=`pwd`
cd
make config T=x86_64-native-linux-gcc
sed -i ‘s/CONFIG_RTE_LIBRTE_PMD_AESNI_MB=n/CONFIG_RTE_LIBRTE_PMD_AESNI_MB=y/g’ ./build/.config
make test-build -j
./build/app/test -l 3 -n 4 --vdev "crypto_aesni_mb"
cd examples/l2fwd-crypto/
export RTE_SDK="/root/dpdk-stable-19.11.5"
make
./build/l2fwd-crypto -l 1 -n 4 --vdev="crypto_aesni_mb" -- -p 1 --cdev SW --chain CIPHER_HASH --cipher_algo "aes-cbc" --auth_algo "sha1-hmac"


I just wish to understand if this is not the right forum to ask these kind of queries.
If it is not, can someone point me to the right place for any further questions regarding crypto libraries in DPDK?

Thanks and Regards,
Surajit

Subject: Using l2fwd-crypto sample app
Hi DPDK Experts,

We are working on expanding our DPDK application to do IPSec based encryption.
To that end I was trying out the sample application provided.
But, I am hitting an error which is probably configuration related.

My DPDK version:
dpdk-stable-19.11.5
OS: CentOS Linux release 7.7.1908 (Core)
Kernel: 3.10.0-1062.el7.x86_64

Command run with options and output:
./l2fwd-crypto -l 0-1 -n 4 --vdev "crypto_aesni_mb0" --vdev "crypto_aesni_mb1" -- -p 0x3 --chain CIPHER_HASH --cipher_op ENCRYPT --cipher_algo aes-cbc --cipher_key 00:01:02:03:04:05:06:07:08:09:0a:0b:0c:0d:0e:0f --auth_op GENERATE --auth_algo aes-xcbc-mac --auth_key 10:11:12:13:14:15:16:17:18:19:1a:1b:1c:1d:1e:1f
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: failed to parse device "crypto_aesni_mb0"
EAL: Unable to parse device 'crypto_aesni_mb0'
EAL: Error - exiting with code: 1
  Cause: Invalid EAL arguments


I am not sure what is causing the error failed to parse device "crypto_aesni_mb0"
Is there a specific driver that needs to be loaded? Or is there a hardware dependency?
I am using virtio nic to test out the app.
Please suggest if the info I have provided is sufficient to determine the cause?
