Description

There is an odd problem with tar VFS in 4.8.30. The problem does not exhibit in 4.8.29. I am on Arch Linux and at least 1 other user can reproduce the issue.

Steps to reproduce:

  1. curl -O ​https://geo.mirror.pkgbuild.com/core/os/x86_64/gcc-13.2.1-3-x86_64.pkg.tar.zst
  2. open the file "gcc-13.2.1-3-x86_64.pkg.tar.zst" in mc
  3. navigate to /usr/bin inside the archive
  4. copy (F5) the file "gcc" somewhere e.g. /tmp
  5. outside of mc, execute `file /tmp/gcc'

It will show the file type as:

"POSIX tar archive"

When of course it should be:

"ELF 64-bit LSB executable"

I haven't git bisected (yet) but I do note some new tar functionality mentioned in the 4.8.30 release notes.

Thanks

Unfortunately the source is not git bisectable. It bombed out with a compilation failure at:

These are hardlinks. Support of hard links is broken.
