sys-kernel/gentoo-sources-2.6.25-r1 CONFIG_TMPFS=y CONFIG_TMPFS_POSIX_ACL=y When coreutils is built with USE=xattr, cp exits abnormally when copying on a tmpfs mount. Using "cp --attributes=-" or re-building coreutils with USE=-xattr succeeds. A downgrade to coreutils-6.10-r1 does not help. Reproducible: Always Steps to Reproduce: 1. mount -t tmpfs none /tmp 2. touch /tmp/foo 3. cp /tmp/foo /tmp/bar; echo $? Actual Results: cp: listing attributes of `/tmp/foo': Invalid argument 1 Expected Results: 0 Portage 2.1.5_rc5 (default-linux/x86/2007.0/desktop, gcc-4.2.3, glibc-2.7-r2, 2.6.25-gentoo-r1 i686)

While tmpfs does support POSIX ACLs, that support does not imply extended attributes support. For most file systems you will see the following: CONFIG_EXT3_FS=y CONFIG_EXT3_FS_XATTR=y CONFIG_EXT3_FS_POSIX_ACL=y However, as you've clearly shown, your tmpfs does not have the option to enabled extended attributes. If you need this support, it's time to break out the text editor, compiler and subscribe to the LKML.
USE=xattrs cp should not fail even if the filesystem it's running on does not support xattrs. I noticed this because the kqemu build runs cp in the source tree, which fails and terminates compilation. You're right, ACLs are unrelated.
I consider it a bug to silently ignore the fact that all data was not actually copied. The question is, what extended attributes do you have on those files?
There are no extended attributes on those files whatsoever. cp actually copies all the data over, it just tries to copy attributes before copying permissions, and falls over when the source filesystem returns EINVAL.
Speaking of which, I've just noticed that mv suffers from the same problem (when it can't use rename()), and --attributes=- does not work as a workaround, since it doesn't understand that option.
Thanks for reopening! Back to where we started... :)
we could always just drop the xattrs patch completely
should be fixed with coreutils-7.1
