Title:
only user.* extended attributes restored upon extraction
Status in GNU tar:
Unknown
Status in tar package in Ubuntu:
New
Status in tar package in Debian:
New
Bug description:
The tar info page and upstream documentation indicate that when
--xattr is used "all names are stored in the archive (or extracted, if
using '--extract')", however when using --xattr with extract the
security.capability extended attributes are not restored. If one also
uses "--xattrs-include=*" then the security.capability extended
attributes will be restored.
[Test Case]
mkdir orig restore
touch orig/file_with_capability_and_user_xattr
setcap cap_net_raw=p orig/file_with_capability_and_user_xattr
(eoan-amd64)root@impulse:/tmp# getfattr -m . -d
orig/file_with_capability_and_user_xattr
# file: orig/file_with_capability_and_user_xattr
security.capability=0sAAAAAgAgAAAAAAAAAAAAAAAAAAA=
user.testkey="testvalue"
(eoan-amd64)root@impulse:/tmp# tar c --xattrs --acls --directory orig/ . |
tar x --xattrs --acls --directory restore/
(eoan-amd64)root@impulse:/tmp# getfattr -m . -d
restore/file_with_capability_and_user_xattr
# file: restore/file_with_capability_and_user_xattr
user.testkey="testvalue"
(eoan-amd64)root@impulse:/tmp# tar c --xattrs --directory orig/ . | tar x
--xattrs --xattrs-include=* --directory restore/
(eoan-amd64)root@impulse:/tmp# getfattr -m . -d
restore/file_with_capability_and_user_xattr
# file: restore/file_with_capability_and_user_xattr
security.capability=0sAAAAAgAgAAAAAAAAAAAAAAAAAAA=
user.testkey="testvalue"
I think tar's extract behavior should be changed to match that of
create so that all names are actually extracted.
