OpenVPN: OpenSSL error: cannot load engine 'padlock'
-
Hi there,
since the latest Built (2.1-BETA1 (i386) built on Thu Jan 24 19:53:59 EST 2013) the hardwarecryptoengine "padlock" couldn't be loaded and therefore the OpenVPN Service refuses to start:
openvpn[93108]: OpenVPN 2.3.0 i386-portbld-freebsd8.3 [SSL (OpenSSL)] [LZO] [eurephia] [MH] [IPv6] built on Jan 24 2013
openvpn[54984]: Exiting due to fatal error
openvpn[54984]: OpenSSL error: cannot load engine 'padlock'If I change or disable the hardware-crypto, OpenVPN works as usual.
On all previous builts, the padlock-engine worked flawlessly. Any ideas? Tell me please, if you need other logs etc.
Greetings!

Can you look up whch was the last buid you were previously on - this may help to locate the day where things broke.
And another thing: Can you hop onto the console and see if padlock.ko is even loaded?
(dmesg might give you an idea whether padlock is loaded or not too)There was some minor change after the OpenVPN 2.3 bump, but at the OpenVPN port side, I don't remember seeing changes related to padlock (yet).
-
I'm not exactly sure, until which built it was working (I think not more than 2 days back it was ok).
dmesg:
…

...I did a test with "openssl speed -evp aes-256-cbc -engine padlock"...that works:
engine "padlock" set.

Since my changeset (a sync from FreeBSD ports) was just merged the day you updated, I looked up if this
may have made it into the build.
https://github.com/bsdperimeter/pfsense-tools/commit/28ad6b86f09f66e61f662b0ee85d1211a4be290aWhile I'm definitely bad at converting time zones back and forward, it does seem that my
commit was only merged after the builder ran.I don't have a padlock capable VIA cpu that, but enabling cryptodev with SNI didn't break things here with the amd64 build from 24th 19:57 EST
I know not all ports are being rebuilt at every run, but maybe @BSDPerimeter could fire
up the OpenVPN port build to make sure your padlock problem is - or is not related to to
the related change :-\ -
I can rebuild it again and see. I know the openvpn22 port was broken quite a bit for 2.0.x builds, but I can't remember if I've rebuilt openvpn 2.3 since then to see if it had any issues.
-
Thanks jim - and supposedly openvpn22 was broken by me while syncing to upstream - sorry about that.
-
OpenVPN 2.3 is rebuilt, new snap run is starting now. Try it again later this evening once it's all uploaded.
-
I've upgraded to the latest built (2.1-BETA1 (i386) built on Fri Jan 25 11:42:50 EST 2013) - still same error as statet above:
…
OpenVPN 2.3.0 i386-portbld-freebsd8.3 [SSL (OpenSSL)] [LZO] [eurephia] [MH] [IPv6] built on Jan 25 2013
openvpn[17542]: Exiting due to fatal error
openvpn[17542]: OpenSSL error: cannot load engine 'padlock'
… -
aha, I see why.
Somehow it's latching onto the openssl from ports, and not from the base system, and we don't compile the openssl from ports with padlock support (not sure when that started to get included…)
-
Next build will be fixed for this.
Also, the next build will include ipsec-tool 0.8.1. Since I had to fix up openssl for this, I went ahead and used it for that.
-
Thank you guys for looking into this.
Upgraded to 2.1-BETA1 (i386) built on Fri Jan 25 17:42:51 EST 2013 FreeBSD 8.3-RELEASE-p5
I get still the same error.
-
That's not the new image.
It's uploading right now.
-
Thank you Jim for your efforts, if things work fine with padlock, I'd like to make a PR to the port maintainer concerning the messed up naming of the padlock patches you had to override in the openssl port.
It doesn't seem many people use padlock - otherwise that would have been fixed upstream already. ;-) -
I'm not sure, if this is already the new image…I just tried it:
2.1-BETA1 (i386) built on Fri Jan 25 22:52:45 EST 2013 FreeBSD 8.3-RELEASE-p5
Still no working OpenVPN with padlock enabled.
-
Same error? Different error?
-
I still get the same error.
-
ok, I think I see what it is now, it didn't copy all of the package version's files to the image, so it's missing the .so files for the other engines. I'll fix that shortly.
-
OK the next new image to go up should have the fixes.
It's not up yet, it will take ~3-4 hours to build and upload.
-
New image is up now.
-
Upgraded to the latest built (2.1-BETA1 (i386) built on Sat Jan 26 10:18:38 EST 2013 FreeBSD 8.3-RELEASE-p5):

openvpn[18810]: Initializing OpenSSL support for engine 'padlock
…It works again :)
Thanx jimp & MatSim for the fast fix. You guys doing an amazing work!
