Crypto Failure in ziti-edge-tunnel

janst · September 8, 2023, 12:45pm

Hi there,

I am currently experiencing issues with my OpenZiti setup. I configured a service within the OpenZiti ZAC to allow accessing an webpage remotely from my Windows machine and also installed WSL. This webpage is running on a bare metal Linux machine (Docker container with exposed port 80), here I have ziti-edge-tunnel for Linux installed.

The issue is now that randomly, when I try to access this webpage through OpenZiti, I get this error in the logs of the machine, that this actually hosting the webpage and running a Linux ziti-edge-tunnel:

Sep 08 13:36:21 service-vm ziti-edge-tunnel[137954]: (137954)[      857.489]   ERROR ziti-sdk:connect.c:845 conn_inbound_data_msg() /github/workspace/build/_deps/ziti-sdk-c-src/library/connect.c:836 - crypto_secretstream_xchacha20poly1305_pull(&conn->crypt_i, plain_text, &plain_len, &tag, msg->body, msg->header.body_len, NULL, 0) => -1 (Unknown error -1)

How is this visible to a user then ?
-> The webpage does just not load in the browser or only after random retries.

This happens mostly when I have just reconfigured my Intercept config for this particular service, but also randomly from time to time. What I have noticed is that is seems to happen more often, when I try to reach the webpage from my windows client, than directly from the wsl ...

Here is my configuration of this setup:

I have also captured a raw tcpdump on the linux machine that is hosting the webpage and logs from both of my routers, as well as the control plane, all of them in verbose mode - but I would prefer to share them privately, because of compliance reasons

It looks like this is the same issue @ekoby has been working to address. Note from @ekoby:

I believe we have a handle on the issue:

Stale terminator data can be caused when edge SDK(ziti-edge-tunnel) loses connection to the ER. Due to the nature of the disconnect ER may not notice that for a long time
When edge SDK(ziti-edge-tunnel) rebinds it creates a new terminator with new crypto material, but stale terminator data may be sent to the dialing client (see point 1)

to address this issue, we are doing the following:

Setting TCP keep-alive on inbound ER connections -- connection losses are detected much faster by ERs and stale terminators are cleanup much sooner enable TCP keep-alive on inbound connections by ekoby · Pull Request #57 · openziti/transport · GitHub
edge SDK (ziti-edge-tunnel) will keep crypto material between re-binds that way, even if the client gets data from a stale terminator, it should still be usable for end-to-end encryption preserve crypto material between rebinds by ekoby · Pull Request #546 · openziti/ziti-sdk-c · GitHub

Hi @smilindave26,

thanks for the reply!
I totally forget to mention the versions I'm using:

ziti-edge-tunnel (linux): 0.22.7
ziti-desktop-edge (windows tunneler): App 2.1.16.0 / Service 2.1.16
ziti-router(s): 0.29.0
ziti-controller: 0.29.0

Are these fixes already merged into the versions I'm using ?

BR

smilindave26 · September 11, 2023, 12:25pm

enable TCP keep-alive on inbound connections by ekoby · Pull Request #57 · openziti/transport · GitHub was released in v0.30.32 (ziti controller/router)

preserve crypto material between rebinds by ekoby · Pull Request #546 · openziti/ziti-sdk-c · GitHub was released in v0.34.0 (ziti-edge-tunnel)

janst · September 11, 2023, 1:02pm

For ziti controller/router I can only see v0.30.3 as latest version available, see Releases · openziti/ziti · GitHub

For ziti-sdk-c I can also only see v0.33.4, see Releases · openziti/ziti-sdk-c · GitHub

I have also checked the ziti-tunnel-sdk repo and I saw that the latest release ziti-edge-tunnel v0.22.7 uses v0.33.4 of the ziti-sdk-c, see https://github.com/openziti/ziti-tunnel-sdk-c/blob/v0.22.7/CMakeLists.txt

smilindave26 · September 11, 2023, 1:25pm

Apologies - I meant v0.30.2 for openziti/ziti (Release v0.30.2 · openziti/ziti · GitHub). Going with the latest (v0.30.3) is generally a good idea.

Apologies again on ziti-sdk-c and ziti-tunnel-sdk-c! You're correct. v0.34.0 of ziti-sdk-c is only in draft-release. I'll pour myself another cup of coffee right now and get back to you on the status later today.

smilindave26 · September 11, 2023, 2:29pm

I spoke with @ekoby (back from vacation today). He still needs to do some testing on the ziti-sdk-c update with ziti-edge-tunnel. We hope to get this released later this week.

janst · September 12, 2023, 6:40am

Sounds great, thank you!

janst · September 14, 2023, 6:47am

Is the ziti windows tunnel also affected by this fix and if yes - will there be a new release ?

TheLumberjack · September 15, 2023, 11:57am

The Ziti Desktop Edge for Windows also uses the CSDK and Tunneler SDKs, so I would expect it to be similarly affected.

Yes, we plan to make a release for it as soon as we can.
