GNU libc currently contains an implementation of RPC (in the ‘sunrpc/’
directory) under the following copyright and license:
Copyright (C) 1984, Sun Microsystems, Inc.
Sun RPC is a product of Sun Microsystems, Inc. and is provided for
unrestricted use provided that this legend is included on all tape media
and as a part of the software program in whole or part. Users may copy
or modify Sun RPC without charge, but are not authorized to license or
distribute it to anyone else except as part of a product or program
developed by the user.
SUN RPC IS PROVIDED AS IS WITH NO WARRANTIES OF ANY KIND INCLUDING THE
WARRANTIES OF DESIGN, MERCHANTIBILITY AND FITNESS FOR A PARTICULAR
PURPOSE, OR ARISING FROM A COURSE OF DEALING, USAGE OR TRADE PRACTICE.
Sun RPC is provided with no support and without any obligation on the
part of Sun Microsystems, Inc. to assist in its use, correction,
modification or enhancement.
SUN MICROSYSTEMS, INC. SHALL HAVE NO LIABILITY WITH RESPECT TO THE
INFRINGEMENT OF COPYRIGHTS, TRADE SECRETS OR ANY PATENTS BY SUN RPC
OR ANY PART THEREOF.
In no event will Sun Microsystems, Inc. be liable for any lost revenue
or profits or other special, indirect and consequential damages, even if
Sun has been advised of the possibility of such damages.
The clause granting redistribution,
Users may copy or modify Sun RPC without charge, but are not
authorized to license or distribute it to anyone else except as

does not seem to meet the Free Software Definition. It forbids
redistribution except “as part of a product or program developed by
the user”. So recipients who have not developed the “program or
product” may not redistribute the work under this license.
Perhaps the simplest resolution for this would be for the GNU libc
maintainers to receive a different, free license for this code from
Sun, like the GNU GPLv2 or GPLv3.
> receive a different, free license for this code from Sun, like the GNU GPLv2
The above licenses may be incompatible with releasing the glibc work as a whole
under the LGPL.
Receiving the RPC code from Sun under a compatible license (ideally, the same
license terms as the bulk of glibc itself) would be best.
Suspended until some legal people picks this up.
This has been fixed in the git tree. Marking the bug as fixed.

I'm glad to know that. Can you please put a link to the specific change in the tree which fixes this bug?
This looks like git commit 9bbd0ddc:

Great. So the license terms for Sun RPC are now a BSD-style 3-clause (attribution, no-endorsement) license, which meets the free software definition.
Thank you to everyone involved in getting this software under free-software terms!
