Lluís Batlle i Rossell 202ebf794c vm/rpm/rpm-closure.pl: make it deterministic
Some recent perl version introduced "keys" to return the keys

based on the order, this randomness affects what packages get into the
closure.

This problem may be in other nix perl scripts.

nixos/vm-tests: Remove msize mount option
This seems to be the root cause of the random page allocation failures
and @wizeman did a very good job on not only finding the root problem
but also giving a detailed explanation of it in #10828.

Here is an excerpt:

  The problem here is that the kernel is trying to allocate a contiguous
  section of 2^7=128 pages, which is 512 KB. This is way too much:
  kernel pages tend to get fragmented over time and kernel developers
  often go to great lengths to try allocating at most only 1 contiguous
  page at a time whenever they can.

  From the error message, it looks like the culprit is unionfs, but this
  is misleading: unionfs is the name of the userspace process that was
  running when the system ran out of memory, but it wasn't unionfs who
  was allocating the memory: it was the kernel; specifically it was the
  v9fs_dir_readdir_dotl() function, which is the code for handling the
  readdir() function in the 9p filesystem (the filesystem that is used
  to share a directory structure between a qemu host and its VM).

  If you look at the code, here's what it's doing at the moment it tries
  to allocate memory:

    buflen = fid->clnt->msize - P9_IOHDRSZ;

    rdir = v9fs_alloc_rdir_buf(file, buflen);

  If you look into v9fs_alloc_rdir_buf(), you will see that it will try
  to allocate a contiguous buffer of memory (using kzalloc(), which is a
  wrapper around kmalloc()) of size buflen + 8 bytes or so.

  So in reality, this code actually allocates a buffer of size
  proportional to fid->clnt->msize. What is this msize? If you follow
  the definition of the structures, you will see that it's the
  negotiated buffer transfer size between 9p client and 9p server. On
  the client side, it can be controlled with the msize mount option.

  What this all means is that, the reason for running out of memory is
  that the code (which we can't easily change) tries to allocate a
  contiguous buffer of size more or less equal to "negotiated 9p
  protocol buffer size", which seems to be way too big (in our NixOS
  tests, at least).

After that initial finding, @lethalman tested the gnome3 gdm test
without setting the msize parameter at all and it seems to have resolved
the problem.

The reason why I'm committing this without testing against all of the
NixOS VM test is basically that I think we can only go better but not
worse than the current state.

vmTools.commonDebPackages: Add "mawk".
While debugging an issue with running NixOps tests, I found out that the
output from debClosureGenerator is not deterministic.

The reason behind this is the way how Provides and Replaces fields are
handled. I haven't yet found out what's the exact issue, but so far
packages "Provides" are more or less picked at random.

So, running the NixOps Hetzner tests we get either mawk, original-awk or
gawk altering on every invocation.

While for the test it isn't poisionous whether wi have mawk or gawk,
having original-awk certainly is, because live-build only works with
mawk or gawk.

The best solution would obviously be to make debClosureGenerator
deterministic, but in the case of "Provides: awk", we can safely pick
mawk by default, because the latter has a "Priority: required" in its
package description.

This also has the advantage that we can safely cherry-pick this to
release-15.09 because it's very unlikely that we'll break the
debClosureGenerator by adding a dependency to commonDebPackages.

vm/windows: Replace binary with cross cygwinSetup.
As the official Cygwin setup binary download doesn't come in snapshots
or even versioned, the fetchurl of setup.exe will frequently fail, which
in turn will annoy us as hell (or at least me).

One warning though: The fetchurl is currently broken and the cross-build
might not work yet for example on mingw32 (mingw-w64 branch on its way),
but the upstream URL has already changed and the new version contains a
bug (not yet tracked down) which breaks our Windows bootstrap process.

So to conclude: If it's already broken, make it at least "less broken".

"Not broken" is coming soon with the merge of the mingw-w64 branch.

This function is quite similar to runInLinuxVM, but also ensures that
the builder is run decoupled of the Nix store and using the userland

We're now picking up the environment variables saved in the previous
commit.

The reason we suppress all errors from the source operation is that it
would emit a ton of errors because we're trying to set read-only
variables.

Also, detecting whether the origBuilder is using the default builder
from the stdenv is currently a bit of a workaround until we have a
specialized pseudo-cross-stdenv someday in the future[TM].

vm/windows: Fix perms of the Samba shares.
We now map all guest accounts to the root user, because in the end the
permissions of the current user boil down to the build user of the Nix
builder of the host. That way it's not possible to gain more permissions
at all and just makes the VM communication a lot easier.

However, setting "writable" to yes instead of "read only" to no doesn't
change anything here, I just found it to be clearer.

Also, we now no longer need to have a "nobody" user.

vm/windows: Avoid shadowing the Nix store.
This is done by putting the non-initrd /nix/store into a subdirectory,
which we then chroot to and pass along the SSH command.

Also, we now collect the exit code after the chroot command and power
off the VM thereafter, because the store is no longer shadowed and we
have still access to the busybox inside the initrd.

vm/windows: Remove Samba from installMode.
This should trim down possible dependencies on the base installation and
hereby reduce the need for reinstallation of the damn VM to only changes
that affect the Windows installation and the base Cygwin + OpenSSH
setup.

vm/windows: Implement and use "xchg" share.
This now finally introduces our xchg share and also uses it for
exchanging state while suspending a VM. However, accessing the _real_
Nix store still isn't possible because we're shadowing the directory in
the initrd.

vm/windows: Reintroduce setting up /nix/store.
Now we're doing this at the point where we're saving the VM state.
Unfortunately it's not quite right, because the controller VM is shut
down _before_ we're saving the state, so the share gets disconnected
despite autodisconnect being deactivated during setup.

We can get around this issue by finally introducing the xchg share,
which is the last item to be implemented before we can merge to master.

vm/windows: Properly escape shell command.
Security-wise it's not a big issue because we're still sandboxed, but I
really don't want to write something like \\\\\\\\192.168.0.2\\\\share
in order to set up network shares.

vm/windows: Don't init /nix/store on install.
We're going to do this during the suspendedVM phase, so we're able to
more easily change the shares without reinstalling the whole VM.

vm/windows: Wait for VDE switch to startup.
This could possibly cause flapping whenever qemu is too fast in starting
up. As we are running with the shell's -e flag, the socat check also
ensures that the VDE switch is properly started and causes the whole
build to fail, should it not start up within 20 seconds.

vm/windows: Split install into several stages.
These stages are in particular:

 * Install of the bare Windows VM with Cygwin and shut down.
 * Boot up the same VM again without the installation media and dump the
   VMs memory to state.gz.
 * Resume from state.gz and build whatever we want to build.

Every single stage involves a new "controller", which is more like an
abstraction on the Nix side that constructs the madness described in
276b72fb93.

This is kinda stupid to do every little time the file is automatically

it will become a major annoyance or not, and if yes, we might be forced
to include it in our source tree.

vm/windows: Move creating SSH key into install/.
This SSH key is specifically only for accessing the installed Cygwin
within the Windows VM, so we only need to expose the private key. Yes,
you heard right, the private key. It's not security-relevant because the
machine is completely read-only, only exposed to the filesystem and
networking is not available.
