- allow namespace to be omitted when using a namespace-prefixed attribute
name, a la Linux.
- Improve hexdump for getextattr -x
- Add more display option for binary attributes, using vis(3)
- Add a -i option to setextattr to get the attribute value from file, so
that we can set binary values
filesystem in which format extended attribute shall be listed.
There are currently two formats:
- NUL-terminated strings, used for listxattr(2), this is the default.
- one byte length-pprefixed, non NUL-terminated strings, used for
extattr_list_file(2), which is obtanined by setting the
EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9)
This approach avoid the need for converting the list back and forth, except
in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may
have requested EXTATTR_LIST_PREFIXLEN.
Modify lsextattr(8) so that it does not expect each attribute name to be
prefixed by its length. This enable extattr_list_(file|link|fd) to
return a buffer matching its documentation. This also makes the interface
similar to what Linux and FUSE do, which is nice for interoperability.
Note that since we had no EA implementation supporting listing, we do
not break anything.
Also use name under which it is installed as main internal name.
Comment out reference to extattr(2) which doesn't exist on NetBSD
(a reference to extattr(3) still remains).
