From 90ad58a83accbeb8de09de4a55d3e6b429767eae Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 27 Jun 2008 13:32:19 +1000 Subject: [XFS] Check for invalid flags in xfs_attrlist_by_handle. xfs_attrlist_by_handle should only take the ATTR_ flags for the root namespaces. The ATTR_KERN* flags may change at anytime and expect special preconditions that can't be guaranteed for userspace-originating requests. For example passing down ATTR_KERNNOVAL through xfs_attrlist_by_handle will hit an assert in debug builds currently.

Despite beeing wrong this actually harmless in practice because both structures are the same size on all platforms. But this sizeof was the only user of struct attr_multiop so we can just kill it. Also move the ATTR_OP_* defines xfs_attr.h into the struct xfs_attr_multiop defintion in xfs_fs.h because they are only used with that structure, and are part of the user ABI for the XFS_IOC_ATTRMULTI_BY_HANDLE ioctl.

Having these in a single function makes it more complicated and forces to have us a bhv_vattr intermediate structure eating up stackspace. This patch adds a new xfs_ioctl_setattr helper for the XFS ioctls that set these attributes and remove the code to set them through xfs_setattr.

Also rename the ATTR_ flags to XFS_ATTR_ to not conflict with the ATTR_ flags used by the VFS.
