What were you trying to do that didn't work?
Extract a tarball using --one-top-level
What is the impact of this issue to you?
I have had to refactor build scripts to run `mkdir -p <target dir>; tar -C <target dir> x ...` instead of tar --one-top-level <target dir>
Please provide the package NVR for which the bug is seen:
tar-1.35-10.el10.x86_64
How reproducible is this bug?:
Easily AFAIK
Steps to reproduce
#!/bin/bash set -x WORKDIR=$(mktemp -d) trap "rm -rf $WORKDIR /tmp/tar-one-top-level-test" EXIT cd "$WORKDIR" # Create minimal test archive mkdir -p pkg/usr/lib && echo "test" > pkg/usr/lib/tartest.txt tar czf test.tar.gz -C pkg . && rm -rf pkg echo "tar version: $(rpm -q tar 2>/dev/null || tar --version)" tar zxf test.tar.gz --one-top-level=/tmp/tar-one-top-level-test 2>&1
Expected results
archive is extracted at /tmp/tar-one-top-level-test
Actual results
Cannot mkdir/Cannot open: Invalid cross-device link
++ mktemp -d + WORKDIR=/tmp/tmp.kbE3w6y1Cn + trap 'rm -rf /tmp/tmp.kbE3w6y1Cn /tmp/tar-one-top-level-test' EXIT + cd /tmp/tmp.kbE3w6y1Cn + mkdir -p pkg/usr/lib + echo test + tar czf test.tar.gz -C pkg . + rm -rf pkg ++ rpm -q tar + echo 'tar version: tar-1.35-10.el10.x86_64' tar version: tar-1.35-10.el10.x86_64 + tar zxf test.tar.gz --one-top-level=/tmp/tar-one-top-level-test tar: /tmp/tar-one-top-level-test: Cannot mkdir: Invalid cross-device link tar: /tmp/tar-one-top-level-test/usr: Cannot mkdir: Invalid cross-device link tar: /tmp/tar-one-top-level-test/usr/lib: Cannot mkdir: Invalid cross-device link tar: /tmp/tar-one-top-level-test/usr/lib/tartest.txt: Cannot open: Invalid cross-device link tar: Exiting with failure status due to previous errors + rm -rf /tmp/tmp.kbE3w6y1Cn /tmp/tar-one-top-level-test
