The Solaris version of ZFS does not allow xattrs to be set on symlinks due to the way they implemented the attropen() system call. Linux however implements xattrs through the lgetxattr() and lsetxattr() system calls which do not have this limitation. The only reason this hasn't always worked under ZFS on Linux is that the xattr handlers were not registered for symlink type inodes. This was done simply to be consistent with the Solaris behavior. Upon futher reflection I believe this should be allowed under Linux. The only ill effect would be that the xattrs on symlinks will not be visible when the pool is imported on a Solaris system. This also has the benefit that it allows for SELinux style security xattr labeling which expects to be able to set xattrs on all inode types.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
