23.7 Legacy Series / Re: Will IPSec-MB be integrated at some point?

« on: May 02, 2024, 06:28:09 am »

I am sorry, maybe I am misunderstanding your response but wouldn't OPNsense be able to use the FreeBSD and updated Intel Source version 1.5.1 to update or improve OPNsense support for the feature and improve overall performance?

or are you saying is not applicable? (the entire thing or just a specific part)

I have been reading this thread as I recently have been looking into the benefits of the implementation and wanted to share what I found. I see that another member already found the PDF document from the conference (see atttached).

However, I wanted to share the information I have available with everyone including the GitHub location of the Intel® Multi-Buffer Crypto for IPsec Library (a.k.a. IPsec-MB or IIMB)
=====================================================================
Intel GitHub location of the library - https://github.com/intel/intel-ipsec-mb

=====================================================================
Intel Multi-Buffer Crypto for IPsec Library is highly-optimized software implementations of the core cryptographic processing for IPsec, which provides industry-leading performance on a range of Intel(R) Processors.

=====================================================================
The kernel module for the Intel® Multi-Buffer Crypto for IPsec Library (a.k.a. IPsec-MB or IIMB)
IPsec-MB is not limited to accelerating IPsec, despite the name.
It leverages CPU SIMD instructions to accelerate anything using kernel crypto functions for AES-GCM-128, AES-GCM-256, AES-CBC-128, AES-CBC-256, SHA1, SHA2, and ChaCha20/Poly1305.
This includes IPsec, WireGuard, OpenVPN DCO and more.
=====================================================================

System tuning values that are directly relevant to Intel IIMB performance:
=====================================================================
kern.crypto.iimb.enable_aescbc="1" # default 1 - disabled 0 - Enables handling of AES-CBC. IIMB can be slower than QAT for CBC so this is a toggle to disable handling for AES-CBC while accelerating other algorithms so IPsec-MB and QAT can coexist in such environments. Supported on x86-64 only.
kern.crypto.iimb.enable_multiq="1" # default value determined by number of CPU cores, =<4 CPU cores = "1", 5-8 CPU cores = "2", 9+ CPU Cores = "4" Value represents number of job threads, multiple queues to handle encryption jobs, i.e. each session is bound to a job thread
kern.crypto.iimb.use_engine="1" # default 1 - disable 0 - used to enable and disable iimb feature
kern.crypto.iimb.use_task="1" # default 0 - enable 1 - used to run seperate task queue for running the encryption job completion callbacks.
=====================================================================

Additionally enabling kernel handling of TLS could further lower CPU utilization as TLS processes are handled directly by the kernel
=====================================================================
All three tuner values have to be enabled in order to enable TLS in kernel, TLS in Kernel is supported in FreeBSD 13.0 or newer releases
=====================================================================
kern.ipc.mb_use_ext_pgs="1"
kern.ipc.tls.enable="1"
kern.ipc.tls.ifnet.permitted="1"
=====================================================================
