Git Fatal Error: PRNG is not seeded #19866

j-wozniack · 2024-09-10T14:26:46Z

Checklist:

I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
I've included steps to reproduce the bug.
I've pasted the output of argocd version.

Describe the bug

Upgrading from 2.11.5 to 2.12.3 I keep getting the same git error, that causes the repo server to fail to clone. When I go to check the repo in the list it shows as connected and healthy. However, when I roll back to 2.11.5 the applications sync and there is no issue with git.

I have checked all the recent issues for 2.12.x and not seen any specific to this.

To Reproduce

Upgrade from 2.11.5 to 2.12.3 using the argocd-helm chart, with a repository secret.

Expected behavior

I am able to upgrade from 2.11.5 to 2.12.3 without getting any git errors

I'd like to take this up.

blakepettersson · 2024-09-16T16:48:37Z

Could it be a permutation of #19587?

j-wozniack · 2024-09-16T20:29:44Z

Could it be a permutation of #19587?

I saw that issue before posting this. I verified our credential for the repo is not scoped to a project. We have multiple projects that all share the same repo. But I doubled check it is not scoped incorrectly.

j-wozniack · 2024-09-16T20:31:16Z

For more context (not sure if it will help). The repo is an AWS code commit repo. We are using ssh keys in order to clone.

nitishfy · 2024-09-20T12:17:05Z

I'm already working on couple of issues in Argo CD right now, so if anyone else would like to take this up, feel free to do that. Thanks!

We got the same error when we did upgrade from 2.9.17 to 2.12.3
All applications failed to get the "status" with the following error

Failed to load target state: failed to generate manifest for source 1 of 1: rpc error: code = Unknown desc = failed to initialize repository resources: rpc error: code = Internal desc = Failed to fetch default: `git fetch origin --tags --force --prune` failed exit status 128: PRNG is not seeded fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

After we rollback, everything is back to normal. Is there any workaround?

We have yet to find a work around, we simply rolled back and waiting to hear back on this issue. It isn't strictly urgent but we would like to be able to upgrade eventually.

@j-wozniack can you post the application spec that's failing? along with the secret it's supposed to use? redacted where applicable

We are experiencing the same issue on v2.12.3:
failed exit status 128: PRNG is not seeded
Is there are a way to WA it?

showalter · 2024-10-09T19:58:35Z

It seems like this might only occur when running ArgoCD on FIPS-enabled hosts, and may be caused by the switch to Ubuntu 24.04 as a base image which was done in #18093. I built v2.12.4 with Ubuntu 22.04 as the base image, and that appears to have worked.

reegnz · 2024-10-14T11:45:23Z

We are experiencing this on FIPS-enabled hosts with ArgoCD v2.12.4. We didn't experience the issue on non-FIPS-ed hosts:

ComparisonError: Failed to load target state: failed to generate manifest for source 1 of 1: rpc error: code = Unknown desc = failed to initialize repository resources: rpc error: code = Internal desc = Failed to fetch default: `git fetch origin --tags --force --prune` failed exit status 128: PRNG is not seeded fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

neiljain · 2024-10-22T21:37:38Z

tried upgrading to 2.12.6 and still have the same issue on fips-enabled hosts.

blakepettersson · 2024-10-23T20:26:00Z

It seems like OpenSSL 3 (which is bundled with Ubuntu 24.04) will not run with FIPS-enabled kernels unless OpenSSL has the FIPS provider library bundled with it. Canonical is nice enough to have that locked away in Ubuntu Pro (where we would need to mount a secret in order to install a FIPS-enabled OpenSSL).

nkalscheuer · 2024-11-09T01:32:39Z

On Ubuntu 24, you can compile and install the fips module and install it into your openssl installation.
Video on it here: https://www.youtube.com/watch?v=geAtEXbHaFg
One step missing there is to move the fips.so file to the same folder as the other OpenSSL libs (usually here: /usr/lib/x86_64-linux-gnu/ossl-modules/)
Also make sure you set up the openssl.cnf file correctly from the video. It's a little confusing.

andrii-korotkov-verkada · 2024-11-11T01:26:13Z

@crenshaw-dev, how big are the downsides of reverting to Ubuntu 22?
@blakepettersson, does it effectively mean that Ubuntu won't have necessary support for this in future versions, unless using pro version?

blakepettersson · 2024-11-11T09:14:19Z

@andrii-korotkov-verkada

@blakepettersson, does it effectively mean that Ubuntu won't have necessary support for this in future versions, unless using pro version?

There are basically two* options with Ubuntu 24

Pay Canonical to get access to the pro repos, which has a precompiled version of openssl with fips support
Try to compile the FIPS-module yourself, as @nkalscheuer suggests

Both of those options implies FIPS-users would need to create a custom Dockerfile and build their own Argo CD Docker images.

*there's a third option, which is that FIPS-users would pay some third-party vendor (there are a couple out there) that distributes pre-built "hardened Argo" images with FIPS-support

andrii-korotkov-verkada · 2024-11-11T11:54:51Z

How much do they charge for the pro version?

blakepettersson · 2024-11-11T12:03:26Z

TBH the subscribe page is really confusing. What I think is the case is that the subscription is free if the intent is to have <= 5 Argo instances running, otherwise there's a myriad of options. I guess the idea is to force potential users to contact sales.

andrii-korotkov-verkada · 2024-11-11T12:06:00Z

Can we create this custom Dockerfile for them and start distributing FIPS-compatible image as well?

blakepettersson · 2024-11-11T12:15:15Z

Can we create this custom Dockerfile for them and start distributing FIPS-compatible image as well?

🤷, if there is a way to build the FIPS-module that still works for non-FIPS users, then I guess someone can take a stab at following the guide @nkalscheuer posted and submit a PR for that.

If this is somehow not compatible with non-FIPS usages, I guess the other option would be to build a FIPS-version of Argo CD along with our normal images.
