Description

As shown in the figure, when I import a file of 4EiB or larger into a folder that already contains a 4EiB file, the WebGUI file interface becomes unusable. Restarting the IPFS kubo resolves the issue.

If someone maliciously shares such CIDs, it could cause others to be unable to use IPFS normally.

Thank you for reporting, I think we are missing error handling in ipfs.files.stat call.

Namely, if it returns Type: error we should display a toast notification with Message:

When importing files, IPFS kubo may not check the size of files and folders, but this issue has been categorized under IPFS WebUI.

Can you assign me this issue? I would love to resolve this!

How should I proceed?

@lidel Hey there,
I would like to resolve this issue!
Can you assign this issue to me?

Repro steps

1. Start Kubo

2. Execute

   $ ipfs files cp /ipfs/bafybeie6tqsijf7j6gpow5q3qdjmtqgscrmd2ijl4olpxanbbptmvh7sui/ /_Tsize_test

3. Open Files screen in ipfs-webui. The /_Tsize_test should show just fine.

4. Now, push it over threshold. Execute

   $ ipfs files cp /ipfs/bafybeie6tqsijf7j6gpow5q3qdjmtqgscrmd2ijl4olpxanbbptmvh7sui/ /_Tsize_test/a
   Error: cp: cannot flush the created file /_Tsize_test/a: value of Tsize is too large: 9650499539051867939

5. Now try to reload Files screen in ipfs-webui (or F5). A broken screen will be displayed until the next restart:

   

6. This makes MFS in Kubo b0rked, and if remote MFS pinning is configured it starts showing errors like:

   2025-02-20T23:34:42.076Z	ERROR	remotepinning/mfs	kubo/pinmfs.go:128	pinning reading MFS root (value of Tsize is too large: 9650499539051867939)
   

7. After restart, MFS (Files) loads fine again. The /_Tsize_test exists, but the /_Tsize_test/a will not exist.

If one of top directories is over limit, the ipfs files stat / will error, effectively bricking entire Files screen, so #2327 is not enough. We need to fix this upstream, in Kubo or even Boxo.

We should avoid creating DAGs that are too big, and avoid getting MFS error mid-flush.

@hsanjuan do you have good intuition where should the Tsize check live to avoid cannot flush the created file error? iiuc we need to check and error sooner, before we update DAG in MFS
