            Bug ID: 13406
           Summary: The uid and gid of the soft link is changed after
                    decompressing with the busybox tar
           Product: Busybox
           Version: 1.31.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: xiechengliang1 at huawei.com
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

Soft links created by ordinary users, after being compressed, the root user
uses the busybox tar to decompress, and the owner of the soft link will become
root. 
It is expected that the owner of the soft link will remain unchanged after
decompression. Is this a bug?

eg.
$ ls -l
drwx------    2 test     test             0 Jan  7 16:21 test
lrwxrwxrwx    1 test     test            12 Jan  7 16:21 test_link ->
test/test.sh

$ busybox tar czf test.tar.gz test test_link

$ mkdir result; cd result

# Unzip with the root user, the owner of the soft link becomes root
$busybox tar xzf ../test.tar.gz
drwx------    2 test     test             0 Jan  7 16:25 test
lrwxrwxrwx    1 root     root            12 Jan  7 16:25 test_link ->
test/test.sh
