 copy files from subdirectory

[Message part 1 (text/plain, inline)]
Hello,

I'm a maintainer of the Relax-and-Recover (https://relax-and-recover.org/)
Open Source project and think that I might have found a major regression in
cp, starting somewhere with version 9.

Please see https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/2017414
and https://github.com/rear/rear/issues/2972 for how I found out about this.

Problem:

We use a cp call like the following to copy various files and directory
into a destination path with preserving the structure:

cp --verbose -t DESTINATION -L --preserve=all --parents SOURCE...

Over the last 10+ years that worked well on all Linux distros (ReaR is
build for and tested on nearly all distros), but I recently found out that
on Ubuntu 23.04 this fails like this:

# rm -Rf /tmp/f && mkdir /tmp/f && cp --verbose -t /tmp/f -L --preserve=all
--parents /etc/apt/sources.list && echo yes ; ls -lR
/tmp/f/etc/apt/sources.list
/etc/apt/sources.list
/etc -> /tmp/f/etc
/etc/apt -> /tmp/f/etc/apt
'/etc/apt/sources.list' -> '/tmp/f/etc/apt/sources.list'
cp: ‘etc/apt’: No such file or directory
-rw-r--r-- 1 root root 2437 Apr 23 09:53 /etc/apt/sources.list
-rw-r--r-- 1 root root 2437 Apr 23 09:53 /tmp/f/etc/apt/sources.list
#

Ubuntu 23.04 uses cp (GNU coreutils) 9.1

On Ubuntu 22.04 there is cp (GNU coreutils) 8.32 and the same example works
as expected:

# rm -Rf /tmp/f && mkdir /tmp/f && cp --verbose -t /tmp/f -L --preserve=all
--parents /etc/apt/sources.list && echo yes ; ls -lR
/tmp/f/etc/apt/sources.list /etc/apt/sources.list
/etc -> /tmp/f/etc
/etc/apt -> /tmp/f/etc/apt
'/etc/apt/sources.list' -> '/tmp/f/etc/apt/sources.list'
yes
-rw-r--r-- 1 root root 263 Mär 26 15:20 /etc/apt/sources.list
-rw-r--r-- 1 root root 263 Mär 26 15:20 /tmp/f/etc/apt/sources.list
#

BTW, I checked also on many other distros that ReaR supports and all
distros with cp version 9.1 fail in the same way.

Can you please have a look and advise how to proceed? We at the ReaR
project can of course change our code to use tar for example, but I won't
be surprised if other users will also meet this changed behaviour and maybe
it is indeed a bug.

Kind regards,

Looks like a bug indeed.
The attached patch should address this in coreutils.
Any deployments of coreutils 9.1-9.3 inclusive would need to apply this.

Hi Pádraig,

Wow, nice! That was really quick!

how would this patch get into the affected distros as a bugfix? Then it
would actually help me as I can't ship a patched coreutils with ReaR.

Kind regards,
Schlomo

I expect the process would be something like:

1. merge this change to upstream coreutils (probably tomorrow).
2. apply this change to debian bookworm
   I'd also apply this related patch to bookworm:
   https://github.com/coreutils/coreutils/commit/b54da709a.patch
3. propagate those changes to ubuntu lunar

cheers,
Pádraig

Hi Pádraig,

thank you, that will not yet fix the problem in the older distros? What
about the RPM world with Fedora/RHEL and Archlinux? As far as I can tell
all cp version 9.x are affected by this.

Kind regards,
Schlomo

I'll handle the Fedora 37/38 fixes.
RHEL/Centos and current Archlinux are not affected AFAICS.

Fedora 37 and 38 updates are now pending (cc Kamil):
https://bodhi.fedoraproject.org/updates/FEDORA-2023-65365355b3
https://bodhi.fedoraproject.org/updates/FEDORA-2023-4beb422aac

The Fedora patches should also apply to the debian bookworm package,
so I've opened bugs accordingly at:

https://bugs.debian.org/1035530
https://bugs.debian.org/1035531

Schlomo, the second one is the one you're particularly interested in.

Marking this bug as completed upstream.

cheers,
Pádraig

This is relevant to coreutils-9.3, right? In that case, the only way
I found out Gentoo was affected was by reading bug-coreutils by chance.

It's not feasible for all package maintainers to read all bug trackers
regularly for all software in their distributions.

If it's worth filing bug reports in each distro for, it's either worth
a new release, or at least an email to the distributions <at> lists.linux.dev
mailing list.

Right. Specifically only this bug applies to 9.3. I.e.:

Right. I didn't inform distros that generally go with the latest coreutils
(including Fedora rawhide), as I was planning to do a 9.4 release soonish
to address this (and other bugs), and so it would get picked up automatically.

Thanks for fixing that. This area of the code is confusing, and I 
attempted to simplify/clarify slightly by installing the attached 
cleanup patch. This shouldn't affect behavior.
