[Bug-cpio] filesize inconsistencies?

[Douglas Lewan]

All,

It isn't clear if the following is a bug, but it's a real question. Besides, this was the only cpio-related mailing list that I could find.

I'm writing an emacs application to handle cpio(1) archives. It is intended, in part, to work like tar-mode and dired. However, with some archives (and some entries within those archives, it looks to me like the filesize field is too large by one byte. The archives still unpack properly, but manual checking of the filesize field reflects that bug for those entries.

I think I've reflected the GNU cpio(1) code correctly. I'd like to know if I've stumbled across something known (and therefore also what that is) or if it's a new bug.

Here's the information on what I'm using to debug this:

• OS: Linux Mint 18 (I believe).
• Kernel: 4.4.0-21-generic #37-Ubuntu SMP
• emacs: 24.5
• GNU cpio: 2.11

If you care, a copy of the current source is attached. It will also be posted to the emacs developers' mailing list.

Thanks.
