vfs: Remove {get,set,remove}xattr inode operations

2016-10-08T01:48:36Z

These inode operations are no longer used; remove them. Signed-off-by: Andreas Gruenbacher Signed-off-by: Al Viro

xattr: Add __vfs_{get,set,remove}xattr helpers

2016-10-08T00:10:44Z

Right now, various places in the kernel check for the existence of getxattr, setxattr, and removexattr inode operations and directly call those operations. Switch to helper functions and test for the IOP_XATTR flag instead. Signed-off-by: Andreas Gruenbacher Acked-by: James Morris Signed-off-by: Al Viro

switch ->setxattr() to passing dentry and inode separately

2016-05-28T00:09:16Z

smack ->d_instantiate() uses ->setxattr(), so to be able to call it before we'd hashed the new dentry and attached it to inode, we need ->setxattr() instances getting the inode as an explicit argument rather than obtaining it from dentry. Similar change for ->getxattr() had been done in commit ce23e64. Unlike ->getxattr() (which is used by both selinux and smack instances of ->d_instantiate()) ->setxattr() is used only by smack one and unfortunately it got missed back then.

xattr handlers: Simplify list operation

2015-12-14T00:46:12Z

Change the list operation to only return whether or not an attribute should be listed. Copying the attribute names into the buffer is moved to the callers. Since the result only depends on the dentry and not on the attribute name, we do not pass the attribute name to list operations. Signed-off-by: Andreas Gruenbacher Signed-off-by: Al Viro

tmpfs: listxattr should include POSIX ACL xattrs

2015-12-07T02:34:15Z

When a file on tmpfs has an ACL or a Default ACL, listxattr should include the corresponding xattr name. Signed-off-by: Andreas Gruenbacher Reviewed-by: James Morris Cc: Hugh Dickins Cc: linux-mm@kvack.org Signed-off-by: Al Viro

tmpfs: Use xattr handler infrastructure

2015-12-07T02:34:15Z

Use the VFS xattr handler infrastructure and get rid of similar code in the filesystem. For implementing shmem_xattr_handler_set, we need a version of simple_xattr_set which removes the attribute when value is NULL. Use this to implement kernfs_iop_removexattr as well.

vfs: Distinguish between full xattr names and proper prefixes

2015-12-07T02:33:52Z

Add an additional "name" field to struct xattr_handler. When the name is set, the handler matches attributes with exactly that name. When the prefix is set instead, the handler matches attributes with the given prefix and with a non-empty suffix. This patch should avoid bugs like the one fixed in commit c361016a in the future.
