With kernel v5.5, the only change so far is in the behavior of depmod. In
earlier versions, it was sufficient to copy the contents of
Module.sysmvers from
the vboxdrv directory to the current directory to have the exported
symbols from
vboxdrv be available to another module such as vboxnetflt, etc. With
v5.5, that
no longer works.
The workaround is to pass the path of Module.sysvers to kbuild (make) in
a
symbol named KBUILD_EXTRA_SYMBOLS. The patch file, which has an MIT
license, is
attached. Additional changes were required in the .spec file used to
build an
openSUSE RPM, and I would expect changes to be needed for the RPM or DEB
build
of other distros. As these changes do not exist here as a separate patch
file, I
cannot attach them; however, the meat of the inline builds need to look
like this:
if [ "$module_name" = "vboxdrv" -o \
"$module_name" = "vboxguest" ] ; then
SYMBOLS=""
fi
# create build directory for specific flavor
mkdir -p modules_build_dir/$flavor
# copy sources which will be used to build vbox module in last
step
cp -r $vbox_module/ modules_build_dir/$flavor/
# copy vboxdrv (for host) module symbols which are used by
vboxnetflt
and vboxnetadp km's:
if [ "$module_name" = "vboxnetflt" -o \
"$module_name" = "vboxnetadp" -o \
"$module_name" = "vboxpci" ] ; then
cp $PWD/modules_build_dir/$flavor/vboxdrv/Module.symvers
\
$PWD/modules_build_dir/$flavor/$module_name
SYMBOLS="$PWD/modules_build_dir/$flavor/vboxdrv/Module.symvers"
fi
# copy vboxguest (for guest) module symbols which are used by
vboxsf km:
if [ "$module_name" = "vboxsf" -o \
"$module_name" = "vboxvideo" ] ; then
cp $PWD/modules_build_dir/$flavor/vboxguest/Module.symvers \
$PWD/modules_build_dir/$flavor/$module_name
SYMBOLS="$PWD/modules_build_dir/$flavor/vboxguest/Module.symvers"
fi
# build the module for the specific flavor
make -j2 -C %{_prefix}/src/linux-obj/%{_target_cpu}/$flavor \
%{?linux_make_arch} \
modules M=$PWD/modules_build_dir/$flavor/$module_name \
KBUILD_EXTRA_SYMBOLS="$SYMBOLS" V=1
