I think the first step should be to import the GPLv3 license text to the source tree. Even if the GPLv3-or-later files were eventually deleted from the source tree, they would probably be left in the Git history. Having the GPLv3 license text likewise in the Git history would reduce the risk that other parties inadvertently violate the license when they distribute clones of the GNU Mach Git repository.

I previously listed GPLv2-only files that carry their own license notices. The GNU Mach tree also contains Linux source files that do not contain a license notice; then, linux/src/COPYING specifies GPLv2 for them. linux/dev/drivers/block/genhd.c is one such GPLv2-only file, and it is compiled in. Thus, it seems there is indeed a license conflict.

The licenses were not discussed in the bug-hurd thread where the i386/grub/ code was imported:


In the earlier "GPLv3 and Hurd" discussion, Thomas Bushnell, BSG wrote that "the use of the Linux drivers means that the project as a whole can only be distributed under the GPLv2":


A preferable outcome would be if the FSF relicenses the GPLv3-or-later files to GPLv2-or-later. I hope nobody's rights on the Linux files have become terminated per GPLv2 section 4.

These files in gnumach carry notices saying that they are licensed under GPLv3-or-later:

  • i386/grub/acpi.h
  • i386/grub/compiler.h
  • i386/grub/cpu/io.h
  • i386/grub/cpu/time.h
  • i386/grub/cpu/types.h
  • i386/grub/err.h
  • i386/grub/misc.h
  • i386/grub/mm.h
  • i386/grub/symbol.h
  • i386/grub/time.h
  • i386/grub/types.h
  • i386/i386at/acpi.c
  • i386/i386at/acpihalt.c
  • kern/gsync.c
  • kern/gsync.h
  • gitlog-to-changelog (not used during the build)

The gnumach source tree however does not include a copy of the GPLv3.

These files in gnumach carry notices saying they are dual licensed under MPLv1.1 or GPLv2-only:

  • linux/pcmcia-cs/include/pcmcia/bulkmem.h
  • linux/pcmcia-cs/include/pcmcia/bus_ops.h
  • linux/pcmcia-cs/include/pcmcia/ciscode.h
  • linux/pcmcia-cs/include/pcmcia/cisreg.h
  • linux/pcmcia-cs/include/pcmcia/cistpl.h
  • linux/pcmcia-cs/include/pcmcia/cs.h
  • linux/pcmcia-cs/include/pcmcia/cs_types.h
  • linux/pcmcia-cs/include/pcmcia/driver_ops.h
  • linux/pcmcia-cs/include/pcmcia/ds.h
  • linux/pcmcia-cs/include/pcmcia/mem_op.h
  • linux/pcmcia-cs/include/pcmcia/ss.h
  • linux/pcmcia-cs/modules/bulkmem.c
  • linux/pcmcia-cs/modules/cirrus.h
  • linux/pcmcia-cs/modules/cistpl.c
  • linux/pcmcia-cs/modules/cs.c
  • linux/pcmcia-cs/modules/cs_internal.h
  • linux/pcmcia-cs/modules/ds.c
  • linux/pcmcia-cs/modules/ene.h
  • linux/pcmcia-cs/modules/i82365.c
  • linux/pcmcia-cs/modules/i82365.h
  • linux/pcmcia-cs/modules/o2micro.h
  • linux/pcmcia-cs/modules/ricoh.h
  • linux/pcmcia-cs/modules/rsrc_mgr.c
  • linux/pcmcia-cs/modules/smc34c90.h
  • linux/pcmcia-cs/modules/ti113x.h
  • linux/pcmcia-cs/modules/topic.h
  • linux/pcmcia-cs/modules/vg468.h
  • linux/pcmcia-cs/modules/yenta.h
  • linux/pcmcia-cs/wireless/hermes.c
  • linux/pcmcia-cs/wireless/orinoco.c

These files in gnumach carry notices saying they are licensed under GPLv2-only:

  • linux/src/drivers/scsi/BusLogic.c
  • linux/src/drivers/scsi/BusLogic.h
  • linux/src/include/net/ax25.h

As the FSF says neither GPLv2-only nor MPLv1.1 is compatible with GPLv3-or-later, it seems there is a license conflict if these files are actually linked in.


The Debian gnumach package does not seem to build the pcmcia and BusLogic drivers. Anyway, it is surely a bug that the GPLv3-or-later files are included without a copy of the license.
