DFSG NEW review for mplapack version 3.0.1+ds-1

Summary

Licensing is DFSG-compliant and debian/copyright is accurate: No
Packaging is of good quality: No
Issues: 2 blocker, 1 important, 1 minor
debian/watch: version 5
debian/copyright: machine-readable
Scan before the review: nothing found

Licensing

All licences in the tree are DFSG-free (BSD-2, LAPACK-style BSD-3, FSF permissive, GPL-2+/GPL-3+ with Autoconf or Libtool exceptions), no non-free wording exists, and debian/copyright is DEP-5 with a correct Format, Files-Excluded matching the repack (the external/ tree holds only build stubs). But the file is inaccurate in three places: the 31 CUDA sources under mpblas/optimized/dd/cuda/ carry Copyright (c) 2010-2011 RIKEN, which the Files: mpblas/* mplapack/* stanza does not name; aclocal.m4 embeds pkg.m4, whose copyright holders (Scott James Remnant, Dan Nicholson) and licence (GPL-2+ with Autoconf exception) are not given by the stanza that describes it as FSF-unlimited; and ltmain.sh names Bootstrap Authors as a holder, which the ltmain stanza omits.

Packaging

The packaging is modern and careful otherwise: debhelper compat 14, autoconf buildsystem with an explicit minimal-backend configure line, hardened build, system GMP/MPFR/MPC/gmpfrxx instead of bundled copies, versioned SONAMEs matching the package name, shlibs via dh_makeshlibs, an autopkgtest compiling against both pkg-config modules, DEP-14 gbp.conf and salsa-ci. Standards-Version 4.7.4 is current against Policy 4.7.4.1. One defect must be fixed: libmplapack-mpfr-dev is declared Multi-Arch: same although it installs an architecture-specific generated header at an architecture-independent path, so it cannot be co-installed for two architectures; debian/README.source itself states the -dev package is not Multi-Arch: same.

Issues

blocker licensing 1. Files: mpblas/* does not name RIKEN, the copyright holder of 31 CUDA sources ◂

Files: debian/copyright:37-41, mpblas/optimized/dd/cuda/Rgemm.cu:2-4, mpblas/optimized/dd/cuda/dd_real_cuda.h:2-4
Basis: checked, in the package or with a reference tool
Evidence:

mpblas/optimized/dd/cuda/Rgemm.cu:2 (and the 29 other .cu files plus dd_real_cuda.h): Copyright (c) 2010-2011 RIKEN All rights reserved. The stanza that matches them, Files: mpblas/* mplapack/*, lists only Maho Nakata, The University of Tennessee and The University of Tennessee Research Foundation, The University of California Berkeley, The University of Colorado Denver and NAG Ltd.
Problem: The files are matched by the mpblas/* stanza, so their licence is right (BSD-2-Clause), but a copyright holder named in the file notices is missing from debian/copyright, which therefore misstates the copyright of 31 files.
Fix: Add 2010-2011 RIKEN to the Copyright field of the mpblas/* stanza (or give these CUDA files their own stanza with License: BSD-2-Clause), keeping the licence unchanged.

blocker licensing 2. aclocal.m4 stanza gives FSF-unlimited and only FSF as holder, but the file embeds pkg.m4 under GPL-2+ with Autoconf exception (Scott James Remnant, Dan Nicholson) ◂

Files: debian/copyright:96-105, aclocal.m4:22-49
Basis: checked, in the package or with a reference tool
Evidence:

aclocal.m4:26-30: dnl Copyright © 2004 Scott James Remnant <scott@netsplit.com>. dnl Copyright © 2012-2015 Dan Nicholson <dbn.lists@gmail.com> dnl ... dnl it under the terms of the GNU General Public License as published by dnl the Free Software Foundation; either version 2 of the License, or while debian/copyright says Files: aclocal.m4 Makefile.in */Makefile.in / Copyright: 1992-2021 Free Software Foundation, Inc. / License: FSF-unlimited.
Problem: The stanza's last-match rule makes it cover all of aclocal.m4, so the file is described with a single permissive licence and one holder, while roughly lines 22-49 of it are the GPL-2+ pkg.m4 macro set with the Autoconf exception, copyright Scott James Remnant and Dan Nicholson. Both the holder list and the licence short name are wrong for that part of the file, and the GPL text and exception it relies on are not reproduced or pointed to.
Fix: Split the stanza: keep aclocal.m4 under FSF-unlimited for the automake part, and add a Files: aclocal.m4 stanza (placed after it) with Copyright: 2004 Scott James Remnant <scott@netsplit.com> and 2012-2015 Dan Nicholson <dbn.lists@gmail.com> and License: GPL-2+ with Autoconf exception, reproducing the exception and pointing to /usr/share/common-licenses/GPL-2.

3. [important] [packaging] libmplapack-mpfr-dev is Multi-Arch: same but installs an architecture-specific header at /usr/include/mplapack/mplapack_config.h

Files: debian/control:24-26, debian/libmplapack-mpfr-dev.install:1, debian/README.source:27-30
Basis: checked, in the package or with a reference tool
Evidence:

debian/control for the dev package: Architecture: any Multi-Arch: same while debian/README.source says The runtime package is Multi-Arch: same; the development package is not. and The generated mplapack_config.h contains target configuration (including integer-width choices) and is installed under a common include path. configure.ac:2483-2492 sets mplapack_integer_bits to 64 when sizeof(void*) is 8 and 32 otherwise, then AC_DEFINE_UNQUOTED([MPLAPACK_INTEGER_TYPE], [$mplapack_integer_type]); Makefile.am:234 installs it as nodist_mplapack_include_HEADERS = include/mplapack_config.h under $(includedir)/mplapack.
Problem: Policy 5.6.34.3 requires that, for a given file name, every architecture of a Multi-Arch: same package install the same bit-identical file. mplapack_config.h is generated per architecture (mplapackint is int32_t on 32-bit and int64_t on 64-bit, plus HAVE_STD_FLOAT128, SIZEOF_VOID_P, binary80/128 mode macros) and installed at the architecture-independent path /usr/include/mplapack/mplapack_config.h, so dpkg will refuse to co-install the amd64 and i386 dev packages and the field is simply wrong.
Fix: Remove Multi-Arch: same from libmplapack-mpfr-dev so that control matches README.source and policy, or move the generated header to an architecture-dependent include directory and install a wrapper header that includes it.

4. [minor] [licensing] ltmain.sh stanza does not name the holder Bootstrap Authors

Files: debian/copyright:117-120, ltmain.sh:75, ltmain.sh:1527
Basis: checked, in the package or with a reference tool
Evidence: ltmain.sh:75: # Copyright (C) 2004-2019, 2021 Bootstrap Authors, and ltmain.sh:1527: # Copyright (C) 2010-2019, 2021 Bootstrap Authors; the stanza names only 1996-2019, 2021-2022 Free Software Foundation, Inc.
Problem: A holder named in the file's notices is absent from debian/copyright. The licence itself (GPL-2+ with Libtool exception) is stated correctly, so only the holder line is wrong.
Fix: Add 2004-2019, 2021 Bootstrap Authors (and, if desired, the second 2010-2019 range) to the Copyright field of the Files: ltmain.sh stanza.

Verified

Scan item Bootstrap Authors (ltmain.sh:75, :1527): a copyright line of libtool's generated script; the file's licence is GPL-2+ with Libtool exception, which debian/copyright states correctly. Only the holder line is missing (issue above).
Scan items Dan Nicholson <dbn.lists@gmail.com> (aclocal.m4:27) and Scott James Remnant <scott@netsplit.com> (aclocal.m4:26): the embedded pkg.m4 block, GPL-2+ with Autoconf exception; misdescribed by the aclocal.m4 stanza (issue above).
Scan item RIKEN (31 files: mpblas/optimized/dd/cuda/Rgemm.cu, Rgemm_cuda.cu, the 20 Rgemm_fermi_/Rgemm_tesla_ kernels, the 8 Rsyrk_* kernels, Rsyrk.cu and dd_real_cuda.h): each is BSD-2-Clause, copyright 2010-2011 RIKEN, contributed by Takao, Yasuyoshi and Nakata, Maho; they are CUDA sources not built by this package (--disable-cuda) but shipped as source. Holder missing from debian/copyright (issue above).
Licence inventory of the whole tree: no binary, PDF, image, font, archive or minified file exists; no vendored third-party tree exists either (external/ contains only Makefile.am/Makefile.in stubs and external/cmake/bootstrap.sh, so the Files-Excluded download/patches paths are really absent).
Tree-wide search for non-free terms (non-commercial, no-modification, field-of-use, CC-*-NC/-ND, Good not Evil, Boost, ISC, zlib, public domain) found nothing but ordinary free-licence wording.
Autotools files checked against their own headers and the stanzas that cover them: configure (FSFUL, years match), Makefile.in and aclocal.m4 header (FSF unlimited, 1996-2021/1994-2021), m4/libtool.m4, m4/ltoptions.m4, m4/ltsugar.m4, m4/ltversion.m4, m4/lt~obsolete.m4 (FSFULLR), compile/depcomp/missing/test-driver (GPL-2+ with Autoconf exception), config.guess/config.sub (GPL-3+ with Autoconf exception), install-sh (X11), INSTALL (FSFAP), ltmain.sh (GPL-2+ with Libtool exception), m4/host_cc_flags.m4 (MPLAPACK's own, no separate notice).
MPLAPACK-authored header and source notices sampled across include/, mpblas/reference, mpblas/optimized/mpfr, mpblas/test, mplapack/reference, mplapack/test/matgen, benchmark/, examples/ are the two-clause BSD text with Copyright (c) 2008-20xx Nakata, Maho, which the Files: * stanza covers; include/blas.h and include/lapack.h are Nakata's own BSD-2 headers, not netlib copies.
All 61 occurrences of University of Tennessee notices are inside mpblas/ or mplapack/ (BLAS/LAPACK-derived routines), i.e. covered by the Files: mpblas/* mplapack/* BSD-2-and-BSD-3 stanza; the three-clause text including the LAPACK patent disclaimer is reproduced there. Files say 1992-2007 where the stanza says 1992-2011 (year drift only).
debian/ read in full: control, rules, changelog, copyright, both .install files, .examples, not-installed, clean, tests/control, tests/mpfr-backend, tests/mpfr-backend.cpp, gbp.conf, salsa-ci.yml, README.source, source/format. No debian/patches and no maintainer scripts.
Standards-Version 4.7.4 against the reviewing system's Policy 4.7.4.1: current. debhelper compat 14, so the absent ${shlibs:Depends}/${misc:Depends} in control is correct. Build-Depends on libgmpfrxx-mkii-dev (>= 1.5.0) is satisfiable: apt-cache shows gmpfrxx-mkii 1.5.0+ds-1, Multi-Arch: same, in the archive.
Runtime package ships both SONAMEs (MPLAPACK_LT_VERSION_INFO 3:0:0 from configure.ac:29-32) under /usr/lib/, and debian/rules removes the upstream -Wl,-rpath,$(libdir) from the two Makefiles that build the MPFR libraries (mplapack/reference/Makefile.am:50, mpblas/optimized/mpfr/Makefile.am:94), which is where dh_makeshlibs and the shlibs entries come from.
uscan found the packaged version as the newest upstream release (upstream 3.0.1, packaged 3.0.1+ds).
Every pointer of debian/copyright to /usr/share/common-licenses names a file that is there (GPL-2, GPL-3).

Not confirmed

The scan reported 7 text files larger than 4 MiB scanned only in their first 4 MiB; the read-only tools here give no file sizes, so I could not name them, but every file I found is text source or build input, and nothing in the tree looks like a built artefact.
fable/ and fable/fem/ (about 60 .hpp files) carry no copyright or licence header at all and no licence file of their own; they are only covered by the Files: * stanza claiming Nakata/BSD-2. Nothing in the tree documents their origin, so whether that attribution is right (fable is commonly a third-party library) could not be verified from the package.

Proposed changes

None.
