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 at 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 at impulse:/tmp# tar c --xattrs --acls --directory orig/ . | tar x --xattrs --acls --directory restore/
  (eoan-amd64)root at 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 at impulse:/tmp# tar c --xattrs --directory orig/ . | tar x --xattrs --xattrs-include=* --directory restore/
  (eoan-amd64)root at 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.
