patch: **** can't create temporary file permission denied

Question

I'm trying to build OpenWRT in a docker container. This works fine on windows host platforms and on Linux host platforms but on a MacOS host (after moving the build folder on the host to a case-sensitive volume) I get the following error after running make world V=s:

mkdir -p /workspaces/MyProject/OpenWRT/dl

Now the temp file ppA9ZnfY is created in the OpenWRT/tmp directory, but the file is corrupted, i.e. when I ls on the host system's terminal I get this:

Opening the document info in finder shows this:

Does anyone know what can cause this issue and how to solve it?
