Unusual tar extraction errors when mounting macOS volumes into containers

[calebzulawski]

Issue Description

When mounting macOS volumes into containers, GNU tar errors when extracting symlinks

Steps to reproduce the issue

Run the following commands:

hdiutil create -size 100g -fs "Case-sensitive APFS" -type SPARSE -volname myimage myimage
hdiutil mount myimage.sparseimage
curl https://cdn.kernel.org/pub/linux/kernel/v3.x/linux-3.10.108.tar.gz -o /Volumes/myimage/linux-3.10.108.tar.gz
podman run --rm -v /Volumes/myimage:/myimage -w /myimage ubuntu:24.04 bash -c "tar -xf linux-3.10.108.tar.gz"

Describe the results you received

tar: linux-3.10.108/arch/arm/boot/dts/include/dt-bindings: Cannot open: Permission denied
tar: linux-3.10.108/arch/microblaze/boot/dts/system.dts: Cannot open: Permission denied
tar: Exiting with failure status due to previous errors

Describe the results you expected

Successful extraction (running GNU tar natively on macOS with this archive works)

I have found that busybox tar can extract this file, so GNU tar must be using some syscall podman's volume mapping doesn't like. This is unfortunately not a workaround for my situation, since busybox doesn't support some tar formats I need.
