So yeah, my understanding is that --xattr is broken at the moment, we should fix that as an SRU but we also have the problem that: 1) It's not set by default in either create or extract mode 2) Not all tar implementations we use support it 3) Not all version of gnu-tar we support have it
So as long as we don't get this fixed, we shouldn't rely on xattrs working in tarballs and should investigate alternative methods of shipping and setting those attributes. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to iputils in Ubuntu. https://bugs.launchpad.net/bugs/1313550 Title: ping does not work as a normal user on trusty tarball cloud images.

This allows removing the suid bit. However, the tarball cloud images do not preserve the extended attributes, and thus /bin/ping does not work on a system derived from them. Summary of problem per package: * lxc: ubuntu cloud template needs to extract * download template needs to extract with xattr flags * server side download creation tools need xattr flags * [unconfirmed] tarball caches need creation and extraction with xattr flags * tar: need the '--xattr' and '--acl' flags backported * maas: uec2roottgz needs to use xattr/acl flags * curtin: extraction needs to use xattr/acl flags. * cloud-image-build: needs to create -root.tar.gz with xattr/acl flags To manage notifications about this bug go to: https://bugs.launchpad.net/curtin/+bug/1313550/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
