Summary: rsync -X is ineffective when setting owner/group
Product: rsync
Version: 3.1.0
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P5
Component: core
AssignedTo: way...@samba.org

Patch
Description of problem:
rsync -X preserves extended attributes on files. It works partially; however,
if combined with rsync options which preserve the file owner and/or group, it
is partially ineffective. This is because rsync calls chown(2) after setting
attributes, and chown removes security attributes (as in capabilities(5)).
Steps to Reproduce:
$ touch foo
$ sudo setcap cap_dac_read_search=pe foo
$ getcap foo
foo = cap_dac_read_search+ep
$ sudo rsync -X foo foo.1
$ getcap foo.1
foo.1 = cap_dac_read_search+ep
$ sudo rsync -aX foo foo.2
$ getcap foo.2
