Issue with dpdk-l2fwd-crypto Application SW on Ubuntu 20.04 PC

[sheikfaaruk]

I am testing dpdk application in PC with PCI-E Dual-RJ45 gigabit NIC card to develop a network based application. I have started my project with dpdk 21.08 and Codewarrior IDE.

PC details :

uname -a
Linux mglocadmin-ThinkCentre-M73 5.15.0-105-generic #115~20.04.1-Ubuntu SMP Mon Apr 15 17:33:04 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

The following steps to install DPDK (Data Plane Development Kit) on Ubuntu 20.04:

sudo apt update
sudo apt install build-essential meson python3-pyelftools libnuma-dev pkgconf
wget https://fast.dpdk.org/rel/dpdk-21.08.tar.xz
tar -xf dpdk-21.08.tar.xz
meson build
ninja -C build
meson -Dexamples=all build
sudo ninja install
sudo ldconfig

Setup hugepage in PC:

mkdir -p /dev/hugepages
mountpoint -q /dev/hugepages || mount -t hugetlbfs nodev /dev/hugepages
echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

Setup NIC card in PC:

sudo ifconfig enp2s0f1 down
sudo ifconfig enp2s0f0 down

cd /<Path>/dpdk-21.08/usertools/
sudo modprobe uio
sudo modprobe uio_pci_generic
sudo dpdk-devbind.py -b uio_pci_generic 02:00.0
sudo dpdk-devbind.py -b uio_pci_generic 02:00.1
dpdk-devbind.py -s

NOTE : DPDK-L2fwd application is working

But ,I am unable to get dpdk-l2fwd-crypto to function properly on my Ubuntu 20.04 system. I've checked the dependencies, ensured that DPDK is properly configured, and attempted various troubleshooting steps, but to no avail.

ERROR log:

kindly help us to resolve this issue.

Can you please check whether DPDK is being compiled with "openssl" library.

Below path is must to compile DPDK with openssl:

export PKG_CONFIG_PATH=<OpenSSL lib path>/lib/pkgconfig:$PKG_CONFIG_PATH

Please refer to the following line in flexbuild_lsdk2108_github/packages/apps/networking/dpdk.mk

export PKG_CONFIG_PATH=$(DESTDIR)/usr/local/lib/pkgconfig:$(PKG_CONFIG_PATH) && \

[sheikfaaruk]

Thank you for reply @yipingwang ...

But I was tried to build and run dpdk-l2fwd-crypto application in PC .so I am directly install DPDK not with flex-builder.

Is there any configuration in DPDK i need to change or modify for enable openssl ?

[yipingwang]

As I mentioned previously, please execute the following before building DPDK.

export PKG_CONFIG_PATH=<OpenSSL lib path>/lib/pkgconfig:$PKG_CONFIG_PATH

[sheikfaaruk]

The step which i followed is below :
mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08$ export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig:$PKG_CONFIG_PATH

mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08$ cd build/
mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08/build$ sudo ninja install

mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08/build$ cd examples/
mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08/build/examples$ sudo modprobe cryptodev
mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08/build/examples$ ls /dev/crypto
/dev/crypto
mglocadmin@mglocadmin-ThinkCentre-M73:~/NIC/dpdk-21.08/build/examples$ openssl engine

Still same issue @yipingwang 

[yipingwang · Accepted solution]

After configuring PKG_CONFIG_PATH, you need to recompiling DPDK with "meson arm64-build" command.

For details, please refer to section "Compiling DPDK using meson" in LSDK 21.08 user manual.
