Description Kamil Dudka 2021-02-08 10:29:25 UTC

+++ This bug was initially created as a clone of Bug #1921246 +++

Description of problem:
split --number=K/N can be used when there isn't enough local storage,
and you want to split input to separate output devices in separate runs.

Ever since v8.26 (so including centos 8), there is a nasty
data corruption issue for any file over 128KiB
as part of the input file is skipped incorrectly.

The upstream fix for this is:
https://github.com/coreutils/coreutils/commit/bb21daa1.patch

Is there a bug tracking this for the centos/rhel 8 side of things.
I didn't find one when searching for "split" in the RHEL 8 component

--- Additional comment from Kamil Dudka on 2021-02-08 11:25:23 CET ---

We do not clone Fedora bugs for RHEL proactively, only the other way around.  Given the fact that the upstream patch applies cleanly and fixes a possible data loss, I will clone this one for eventual inclusion in the next update of coreutils in RHEL-8.  Thanks for the hint!
