Enabling cryptodev support for openssl does nothing for me, the engine simply won't show up.

Going to try with uClibc maybe that works better.

Did a clean build with uClibc, no change. I do have /dev/crypto and openssl has been compiled with support for it:

But the engine does not show up. My best guess is that it's currently broken with either the 4.1 kernel, or with the latest openssl library. From what I can gather this code doesn't get used a lot and has bugs. I tried the ocf implementation as well with no luck.

Too bad, huge OpenVPN speedup would be nice

Thanks for trying. Never mind. With the above aes-ppc.pl patch the OpenVPN numbers should be far better than the stock version. Alphasparc has a similar patch in bis builds but this falls back to C code and not the even better assembler core.

Here's my latest score with uClibc:

| r46541 | 1.0.2d | 75964990 | 81707590 | 38163370 | 21985420 | 15164160 | 5524430 | 32340470 | 29271520 | 25452820 | 18.5 | 712.7 68.3 | 57.7 |

Huge increase in AES speed indeed. Valentt will be happy he was chasing these numbers

The 'numbers' are in 1000s of bytes per second processed.

Still slightly slower than BF-CBC (OpenVPN default), but now you should be able to get roughly the same throughput with AES-128.

OK, I got OCF cryptodev working:

Fine. Did you already include kernel md5 ppc module?

Yes, I did. The md5 score went from 75964990 to 108506760.

There's a decrease in SHA1 score though.

EDIT: Still only got 20/20 Mbps with AES-128 through OpenVPN.

Was hoping for a better result than that, but even if it uses the kernel for crypto it's still much slower than IPsec. OpenVPN is userland and needs raw CPU power more than anything.

Here's the build if anybody would like to try:

http://enduser.subsignal.org/~trondah/w … cryptodev/

Did you enable cryptodev in OpenVPN too? Parameter "engine cryptodev".

(Last edited by birnenschnitzel on 2 Aug 2015, 11:09)

Yes I did, and changed cipher to AES-128-CBC.

Hm, Strange...

so you should give the above openssl patch without cryptodev a try.

Maybe of interest too although I do not expect massive performance gains: https://lists.ozlabs.org/pipermail/linu … 21144.html

Not that strange if you think about it. The OpenSSL library can use cryptodev for the encryption but it still have to push the data through the tun interfaces, most likely the speed gains from the kernel are lost on the way. I would think that if you got dedicated SSL hardware and a fast CPU, it would make OpenVPN blazing fast.

I'll try the checksum function as well, as you say there probably won't be a huge difference. Maybe faster WAN/LAN?

Next build is coming up:

r46541:
- Support for USB tethering of Android/iOS devices
- mwan3 for load balancing and failover two or more WAN connections
- Simply plug in your device, enable tethering and enable the mwan3 WAN/USB interfaces
- iOS has a different interface, needs to be changed under Network -> Interfaces -> USB -> Phsyical Settings
- Increased OpenSSL AES speed for PPC / WDR4900

What ports do you need to open for strongSwan ?
I've got a bit of a rubbish set up where my ISP makes me use their router in front of the tp-link...

UDP 500 and 4500.

I added a 443-forwarding rule, but when I try to connect from the internet I get a message that the website may be temporarily disabled or permanently moved.
Internally however it works... Is there a logfile where I can see if the router/firmware might be causing this?
(I'm running on r46541-musl)

There is already a redirect rule for TCP 443 in my build:

config redirect
    option name 'Redirect-TCP-port-443-to-1194-on-wan'
    option src 'wan'
    option src_dport '443'
    option src_ip '!192.168.102.0/24'
    option dest 'lan'
    option dest_port '1194'
    option proto 'tcp'
    option target 'DNAT'
    option reflection '0'

This is used for OpenVPN TCP fallback. If you don't need this just disable/remove the rule. In that case you should stop the OpenVPN TCP instance as well.

Hi arokh,

Thanks for you work! I use the Build r46541 on a WNDR3700 v4 (Nand) and only the Wifi 2.4 GHz device is present. I make a clean flash over tftp but the 5GHz device dont work. Do you have a tip as I Device the 5GHz to run get? Greetings and thanks Meditux

I don't have a V4 to test, but it should work fine with ath9k. Can you see both radios?

I looked at that screen several times and completely missed it...

Thanks!

Maybe I've missed something, but is there a reason that the WNDR3700(v1) isn't being catered for anymore?
I built it from source as well, and despite it saying that the 3700 profile is selected, doesnt seem to build- only the 3700v2 is there.

It's still catered for, I moved it to a new profile: wndr3700_8mb. The wndr3x00 is only for 16MB devices. It won't build unless you have CONFIG_NETGEAR_8MB set.

Interesting, I thought I had tried that profile before- must have only ticked the option in the Global Build Options.

I've got it to build now thanks. THe firmware is starting to get close to the limit of my 3700v1... thinking it might be time to upgrade, finally.

No, i see only radio0 (2.4 GHz)!
