AES-NI instructions…

timmyj9

any reason why my system would say?

padlock0: No ACE support.
aesni0: No SSE4.1 support.

It seems that the issue is still there.
I am on latest snapshot now:

2.2-BETA (amd64)
built on Fri Oct 31 04:59:06 CDT 2014
FreeBSD 10.1-RC4

pfSense is running in ESXi VM. The CPU AES-NI flag appeared in dmesg so ESXi does not hide this flag.
The error message is still the same as other posters.
My CPU: Xeon E3-1231v3. It is the lastest Haswell.

I've seen exactly the same thing during my limited play time with 2.2 on ESXi 5.5u2 and E3-1265Lv2

jimp

Hard to say, but you'd have to compare it with the output on the same hardware running bare metal without ESX.

biggsy

Unfortunately, I haven't got any chance of trying 2.2 on the bare metal but I should probably have mentioned that 2.1.5-RELEASE (amd64) is currently running on the same hardware and ESXi version. AES-NI is showing up in Crypto Hardware Acceleration on that VM.

timmyj9

i can confirm same situation here with the hardware crypto acceleration working in pfSense 2.1 but not 2.2-beta (also under ESXi 5.5)

Please provide information from your dmesg the 20 top rows.

Also the output of kldload -v aesni and dmesg info after.

I do see that message when loading aesni.ko inside a VMware VM, though.

heper

so aes-ni doesn't work inside VM's ?

jimp

I'd wager that has more to do with the hypervisor than the OS since it works on bare metal but it's tough to say for sure.

Hi ,
I had some free time around Christmas and played with new 2.2 RC .
I have tested new VMware 6.0 RC as well as ESXI 5.5 and directly on bare e3-1230v2, and can confirm that the problem with aesni persist with both Hypervisors.

I spend long time to test multiple cases with both 2.1.5 and 2.2 versions of pfsense on VM <->VM scenario. The results is one and the same. no HW acceleration at all.
I also tried my spare e3-1230v2 against my prod, both versions 2.1.5 and looks like HW acceleration is not working as well. speed is capped near ~~ 326 Mbits/sec.
Unfortunately I cannot install 2.2RC in prod to test it…. ... But looks lke HW acceleration works for 2.2.rc
(when i perform tests from 2.2 against 2.1.5 speed is near 400 Mbits/sec , when i test from 2.1.5 against 2.2rc speed is droping to 312 Mbits/sec)
i also have to confirm that pure speed between 2 * VM 2.2rc (vmx3) is like 3.04 Gbits/sec when 2 * vm 2.1.5 (vmx3) is hardly hitting 1.59 Gbits/sec .
unfortunately with no HW acceleration the IPSEC speed is like i said ~~ 350 Mbits/sec.

At the end, I am not an expert, but looks like this "No SSE4.1 support" problem is some misunderstanding in aesni_probe module related to the way vmware reports Features= and Features2= to guest operating system .
(but dont shoot me if i am wrong ) ;)

biggsy

In my brief test of 2.2RC in a VM yesterday, I didn't see the "padlock0: No ACE support/aesni0: No SSE4.1 support" messages but I wasn't watching for them.

With 2.1.5 running on 5.5 U2 everything seems to be OK:

$ dmesg | egrep -i '(SSE|aes.*ni)'

els

My machine has AES-NI and I did a "dmesg" to confirm that. I have site-to-site VPN running and it works (except for the bug with IPSEC widget). How do I tell if AES-NI is being utilized? Do I need to make configuration change to force it to use AES-NI?

Hi,
just tested a fresh FreeBSD 10.1 installation on esxi 5.5u2. AES-NI looks working

uname -a 
FreeBSD  10.1-RELEASE FreeBSD 10.1-RELEASE #0 r274401: Tue Nov 11 21:02:49 UTC 2014     root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

vs the very same VM with pfsense :

jimp

The FreeBSD module does not include our code for IPsec acceleration of AES-GCM. It would not be useful on pfSense in general.

eri--

I will double check this though that should not prevent our module to not attach where freebsd one attaches.
I will post here when resolve that.

EDIT: Oh i forgot the 10.1 FreeBSD does not have any AES-GCM code :)

zanon

Hi, аs long as i could imagine,
the problem is not in specific implementation of AES additions, but in the detection of processor Features and Features2 in aesni_probe module.
but enough for this :)

i really have to share that most of us, people who are using pfsense, are pretty excited of your work guys .

Thank you for everything you are doing .

eri--

Yeah but AES-GCM has more requirments than plain AES-CBC/XTS speedup.
