nfstest_xattr - Extended Attributes tests

nfstest_xattr --server <server> [options]

Verify correct functionality of extended attributes

Extended attributes are name:value pairs associated permanently with files and directories, similar to the environment strings associated with a process. An attribute may be defined or undefined. If it is defined, its value may be empty or non-empty. Extended attributes are extensions to the normal attributes which are associated with all inodes in the system. They are often used to provide additional functionality to a filesystem.

Tests are divided into five groups: getxattr, setxattr, removexattr, listxattr and cinfo. The getxattr tests verify the retrieval of extended attribute values. The setxattr tests verify the creation or modification of extended attributes. The removexattr tests verify the removal of extended attributes. The listxattr tests verify the listing of extended attributes. And finally, the cinfo tests verify the change info returned by the server is correct when the file is either modified or not from a different client.

Furthermore, when a different client is holding a read delegation, verify the delegation is recalled only when creating, modifying or removing an extended attribute. On the other hand, verify the read delegation is not recalled when listing attributes or retrieving their values.

Negative testing is included like retrieval or removal of an extended attribute name which does not exist. Creating an attribute which already exists should fail while using XATTR_CREATE flag. Trying to modify an attribute which does not exist should fail if using XATTR_REPLACE flag.
