Package: libarchive1
Version: 2.8.4-1
Severity: normal
In libarchive/archive_read_disk_entry_from_file.c, there is code
to retrieve ext2 extended file attributes (see chattr(8)) from
regular files and directories but it is not enabled because of
some missing #includes.
Enabling it should only be a matter of applying the patch below
(though you'd probably wants to also add test code) which seems
to work as expected.
