### Known limitations

#### Extended attributes for tar files

In this release, the code that handles `tar` archives was changed to be more
strict and to produce an error when failing to write extended attributes
(`xattr`). The `tar` implementation for macOS generates additional extended
attributes by default when creating tar files. These attribute prefixes aren't
valid Linux `xattr` namespace prefixes, which causes an error when Docker
attempts to process these files. For example, if you try to use a tar file with
an `ADD` Dockerfile instruction, you might see an error message similar to the
following:

```text
failed to solve: lsetxattr /sftp_key.ppk: operation not supported
```

Error messages related to extended attribute validation were improved to
include more context in [v25.0.1](#2501), but the limitation in Docker being
unable to process the files remains. Tar files created with the macOS `tar`
using default arguments will produce an error when the tar file is used with
Docker.

As a workaround, if you need to use tar files with Docker generated on macOS,
you can either:

- Use the `--no-xattr` flag for the macOS `tar` command to strip **all** the
  extended attributes. If you want to preserve extended attributes, this isn't
  a recommended option.
- Install and use `gnu-tar` to create the tarballs on macOS instead of the
  default `tar` implementation. To install `gnu-tar` using Homebrew:

  ```console
  $ brew install gnu-tar
  ```

  After installing, add the `gnu-tar` binary to your `PATH`, for example by
  updating your `.zshrc` file:

  ```console
  $ echo 'PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"' >> ~/.zshrc
  $ source ~/.zshrc
  ```
