In 2942815968, the dependencies for Qt 5
were passed using buildEnv with all the development binaries, headers
and libs. Unfortunately, the build output references that environment
which also increases the size of the runtime closure.
The upstream makefile assumes a common Qt 5 library path, but that's not
the case within Nix, because we have separate paths for the Qt 5
modules.
We now patch the makefile to recognize PATH_QT5_X11_EXTRAS_{LIB,INC} so
that we can pass in the relevant paths from Qt5X11Extras.
In summary, the closure size goes down to 525559600 bytes (501 MB)
instead of 863035544 bytes (823 MB) with vbox-qt5-env.

Putting the kernel modules into the same output path as the main
VirtualBox derivation causes all of VirtualBox to be rebuilt on every
single kernel update.
The build process of VirtualBox already outputs the kernel module source
along with the generated files for the configuration of the main
VirtualBox package. We put this into a different output called "modsrc"
which we re-use from linuxPackages.virtualbox, which is now only
containing the resulting kernel modules without the main user space
implementation.
This not only has the advantage of decluttering the Nix expression for
the user space portions but also gets rid of the need to nuke references
and the need to patch out "depmod -a".

We now no longer need to update VirtualBox manually, which has a few
advantages. Along with making it just easier to update this also makes
the update procedure way less error-prone, for example if people forget
to bump the extension pack revision or to update the guest additions.

Just a small updater which should fetch the latest sha256sums from the
upstream site and check whether the current version is the latest one.
The output is in a JSON file in the same directory, which then will be
used by the Nix expressions to fetch the upstream files.

The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable
To enable specific hardening flags
Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
VirtualBox had support for DBUS even in version 4.x, but it appears that
nothing in our VM test triggered it to load, thus I didn't notice the
runtime error:
rtldrNativeLoad: dlopen('libdbus-1.so.3', RTLD_NOW | RTLD_LOCAL) failed:
libdbus-1.so.3: cannot open shared object file: No such
file or directory
The upstream commits I think are responsible for this to come to surface
are _probably_ (did I ever mention that I love SVN? *cough*) one of
these:

Using $storepath/sbin is deprecated according to commit 98cedb3, so
let's avoid putting anything in .../sbin for the guest additions.
This is a continuation of the initial commit done by @ctheune at
1fb1360, which unfortunately broke VM tests and only changed the path of
the mount.vboxsf helper.
With this commit, the VM test is fixed and I've also verified on my
machine that it is indeed working again.

Within fractions* of a second, the beautifully crafted history and
branching mechanisms of SVN found out the exact revision which caused
this to be visible in version 5.x but not in version 4.x:
https://www.virtualbox.org/changeset?old_path=%2Fvbox%2Ftrunk&old=30933&new_path=%2Fvbox%2Ftrunk&new=30934
Also note the very short URL and the informative changeset message which
shows you exactly what was the issue, I think.
Be warned however, it may contain traces of history amnesia, revision
epilepsy and other related diseases.
As for the issue itself: This was very much broken in 4.x as well, but
it didn't show an error message in the UI. The PulseAudio library is
loaded at runtime and it's not able to do that unless it's in
LD_LIBRARY_PATH.
Now, we're doing the same as with the ALSA libraries: We're hardcoding
the path to the shared object file in patchPhase.
Thanks to @devhell for reporting and testing.

This is espacially cruicial when it comes to Nix 1.9, where we even have
a more restrictive /nix/store. In any event, VirtualBox in hardenend
mode doesn't have to check the /nix/store path, because it's read-only
on NixOS systems. So this check would not introduce more security but
more hurdles, thus I'm removing it (of course _only_ for /nix/store).

Because we have to rely on setuid wrappers on NixOS, we can't easily
hardcode the executable paths and set it 4755. So for all calls, we need
to change the runtime path executable directory to /var/setuid-wrappers/
and for verification we need to retain the executable directory.
Also note, that usually VBoxNetAdpCtl, VBoxNetDHCP, VBoxNetNAT, VBoxSDL
and VBoxVolInfo don't reside in directories that are commonly in PATH,
but in /usr/lib/virtualbox in most mainstream distros. But because the
names of these executables are distinctive enough to not cause
collisions with other setuid programs, I'll leave it like that and not
patch up setuid-wrappers.

Not really changes anything in functionality, but makes it easier to
change the build type to "debug", for example.

Just accidentally found this while debugging and it's needed for

Instead of coping it to $out and later deleting it, we now exclude the
src directory during copy. Also, we no longer cd into the release
directory during installPhase, which should make sure that we are
constantly in $sourceRoot.

We divert to the $out/share/virtualbox directory only if we have
hardening enabled, so let's put the extension pack into
$out/libexec/virtualbox instead if we're compiling without hardening.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
Yes, this is only on the package level, so it's possible to use
VirtualBox for example installed by nix-env -i, which of course doesn't
have access to the functionality provided by the various VirtualBox
kernel modules.

With hardening, we need to go a bit further rather than just allowing
/nix/store being world-writable. We now use fakeroot to make sure the
VBoxExtPackHelperApp won't moan that the files are not owned by root.
They are, but only outside of the chrooted build process.
Another issue with using fakeroot is that it doesn't seem to cope well
with arguments that contain spaces. That's why I've piped the call into
${stdenv.shell}.
Now, the really gory and confusing part is the introduction of
VBOX_PATH_APP_PRIVATE_ARCH_TOP and the change of VBOX_PATH_APP_PRIVATE.
The VBOX_PATH_APP_PRIVATE_ARCH is *only* for modules and is checked by
the hardened implementation against whether things like VMMR0.r0 or
VBoxVMM.so reside in that directory. As a side note: I admit that the
whole libexec directory is quite polluted with stuff that shouldn't be
there, but for now we've broken enough things and will tear apart the
whole structure at some day in the future[TM].
For the confusing part we have VBOX_PATH_APP_PRIVATE_ARCH_TOP, which
_should_ be the same as VBOX_PATH_APP_PRIVATE_ARCH but unfortunately,
the hardened implementation is checking against this directory (in
IsValidBaseDir) for the extension pack(why!?).
Of course, we could put even that into the libexec directory, somewhat
similar as the official package, but after all, let's at least *try* to
separate things.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
We are already checking whether /nix/store has the sticky bit set, so if
it is world-writable as well it doesn't mean that the actual store path
is writable. Let alone the fact that it is only writable during the
build process.
This should fix installing the extension pack when enableExtensionPack
is used.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
VirtualBox with hardening support requires the main binaries to be
setuid root. Using VBOX_WITH_RUNPATH, we ensure that the RPATHs are
pointing to the libexec directory and we also need to unset
VBOX_WITH_ORIGIN to make sure that the build system is actually setting
those RPATHs.
The hardened.patch implements two things:
* Set the binary directory to the setuid-wrappers dir so that
VboxSVC calls them instead of the binaries from the store path. The
reason behind this is because nothing in the Nix store can have the
setuid flag.
* Excempt /nix/store from the group permission check, because while it
is group-writeable indeed it also has the sticky bit set (and also
the whole store is mounted read-only on most NixOS systems), so we're
checking on that as well.
Right now, the hardened.patch uses /nix/store and /var/setuid-wrappers
directly, so someone would ever want to change those on a NixOS system,
please provide a patch to set those paths on build time. However, for
simplicity, it's best to do it when we _really_ need it.

Traversing the full source tree is unneccessary, because the calls are

In most cases, this just meant changing kernelDev (now removed from
linuxPackagesFor) to kernel.dev. Some packages needed more work (though
whether that was because of my changes or because they were already
broken, I'm not sure). Specifics:
* psmouse-alps builds on 3.4 but not 3.10, as noted in the comments that
were already there
* blcr builds on 3.4 but not 3.10, as noted in comments that were
already there
* open-iscsi, ati-drivers, wis-go7007, and openafsClient don't build on
3.4 or 3.10 on this branch or on master, so they're marked broken
* A version-specific kernelHeaders package was added
The following packages were removed:
* atheros/madwifi is superceded by official ath*k modules
* aufs is no longer used by any of our kernels
* broadcom-sta v6 (which was already packaged) replaces broadcom-sta
* exmap has not been updated since 2011 and doesn't build
* iscis-target has not been updated since 2010 and doesn't build
* iwlwifi is part of mainline now and doesn't build
* nivida-x11-legacy-96 hasn't been updated since 2008 and doesn't build
Everything not specifically mentioned above builds successfully on 3.10.
I haven't yet tested on 3.4, but will before opening a pull request.
