If partial then there is not much we can do. Now ENOENT is not a documented errno for copy_file_range() so I'm not sure what we should do with it. I didn't see on the bug above if any data was copied. Could we get more info about that? Searching for "cifs STATUS_OBJECT_NAME_NOT_FOUND" indicates we might be able to retry in this case: https://lists.samba.org/archive/samba/2017-September/211000.html I guess we could be defensive and also fstat(dest_fd) and fallback to standard copy if no data yet transferred. However note the above url is suggesting this error may not be specific to copy_file_range() and just an intermittent cifs thing. I.e. copy_file_range() is just a red herring here, and this just needs fixing in the kernel or server side setup. cheers, Pádraig From unknown Tue Jun 17 22:24:15 2025 X-Loop: help-debbugs@gnu.org Subject: bug#60455: Missing fallback if copy_file_range returns ENOENT?

Or more precisely, ENOENT will be unusual for fd operations, and so falling back to a standard copy should just be restricted to this or similar cases. If this was seen on a single CIFS mount it may be less appropriate as then the user may not want to fall back to a client side copy, when a server side should work. But in this separate mount case, the fallback is appropriate. I guess we could restrict to separate device IDs, but that's probably getting too complicated for this. > Total agreement. Thanks, looks good! Pushed.

Frank Limpert reported that when copying large files across CIFS shares, cp may abort because copy_file_range returns ENOENT sometimes. This sounds like a suspicious kernel bug if CIFS interactions are = sometimes spuriously giving ENOENT, but I'm wondering if coreutils needs to do anything to handle this as well. strace output from his cp invocation: = https://bugs.gentoo.org/attachment.cgi?id=3D842497 Best, sam --Apple-Mail=_37806F89-30F4-4656-AF28-B971FF75EAFA Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- iNUEARYKAH0WIQQlpruI3Zt2TGtVQcJzhAn1IN+RkAUCY7BqwV8UgAAAAAAuAChp c3N1ZXItZnByQG5vdGF0aW9ucy5vcGVucGdwLmZpZnRoaG9yc2VtYW4ubmV0MjVB NkJCODhERDlCNzY0QzZCNTU0MUMyNzM4NDA5RjUyMERGOTE5MAAKCRBzhAn1IN+R kHOXAPoCo6MnpUxze8rR+aZ/8lSBLjvKHi+WRneTTYA/dDsliAD/e3cD2+oRyBBa 0YExNitFpIod27ZW6ywvWlfTgnJXAAg= =9tlj -----END PGP SIGNATURE----- --Apple-Mail=_37806F89-30F4-4656-AF28-B971FF75EAFA-- ------------=_1673185562-12026-1--
