podman is a binary build from libpod : libpod is a library used to
create container pods. podman aims to be *almost* compatible with the
docker cli but doesn't require a docker daemon.

This currently uses a binary-only package, since building
jailer/firecracker all on their own is somewhat complex from my
attempts.
This will later be changed into a source-only build, ideally.

It does not work if the sha256 is not hex, it fails because VBoxExtPackHelperApp requires to be given a hex hash.
See https://github.com/NixOS/nixpkgs/issues/34846 where the same problem was fixed some time ago.
I had to drop xorriso because it didn't seem to want to compile with it
any more, and had to add libopus as a build input because it wouldn't
compile without that.
You can use stdenv.hostPlatform.emulator to get an executable that
runs cross-built binaries. This could be any emulator. For instance,
we use QEMU to emulate Linux targets and Wine to emulate Windows
targets. To work with qemu, we need to support custom targets.
I’ve reworked the cross tests in pkgs/test/cross to use this
functionality.
Also, I’ve used talloc to cross-execute with the emulator. There
appears to be a cross-execute for all waf builds. In the future, it
would be nice to set this for all waf builds.
Adds stdenv.hostPlatform.qemuArch attrbute to get the qemuArch for
each platform.
In a few cases it wasn't clear so I left them as-is.
While visiting these moved other things to nativeBuildInputs
when it was clear they were one of these cases:
* makeWrapper
* archive utilities (in order to unpack src)
* a few of these might no longer be needed but leaving for another day
Unlike docker (cli only) this probably won't work on darwin.

Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =

<details><summary>Version release notes (from GitHub)</summary>
Greetings Singularity containerizers!
This release contains fixes for a _high severity_ security issue affecting Singularity 2.3.0 through 2.5.1 on kernels that support overlay file systems (CVE-2018-12021). A malicious user with network access to the host system (e.g. ssh) could exploit this vulnerability to access sensitive information on disk and bypass directory image restrictions like those preventing the root file system from being mounted into the container.
Singularity 2.5.2 should be installed immediately, and all previous versions of Singularity should be removed. The vulnerability addressed in this release affects kernels that support overlayfs. If you are unable to upgrade immediately, you should set `enable overlay = no` in `singularity.conf`.
In addition, this release contains a large number of bug fixes. Details follow:
## [Security related fixes](https://cve.mitre.org/cgi-bin/cvename.cgi?name=2018-12021)
- Removed the option to use overlay images with `singularity mount`. This
flaw could allow a malicious user accessing the host system to access
sensitive information when coupled with persistent ext3 overlay.
- Fixed a race condition that might allow a malicious user to bypass directory
image restrictions, like mounting the host root filesystem as a container
image
## Bug fixes
- Fix an error in malloc allocation #1620
- Honor debug flag when pulling from docker hub #1556
- Fix a bug with passwd abort #1580
- Allow user to override singularity.conf "mount home = no" with --home option
#1496
- Improve debugging output #1535
- Fix some bugs in bind mounting #1525
- Define PR_(S|G)ET_NO_NEW_PRIVS in user space so that these features will
work with kernels that implement them (like Cray systems) #1506
- Create /dev/fd and standard streams symlinks in /dev when using minimal dev
mount or when specifying -c/-C/--contain option #1420
- Fixed * expansion during app runscript creation #1486
As always, please report any bugs to:

I no longer use rancher and can test this derivation.
Also rancher-compose should have the same version as the rancher cluster
used. So it is better to be build by the user using it rather having a
random version in nixpkgs.

Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.
The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:
```
ISA: ARMv8 {-A, -R, -M}
/ \
Mode: Aarch32 Aarch64
| / \
Encoding: A64 A32 T32
```
At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.
The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

is changed
* User interface: increase proposed disk size when creating new VMs for
Windows 7 and newer
* User interface: various improvements for high resolution screens
* VMM: Fixed problems using 256MB VRAM in raw-mode VMs
* Audio: implemented support for audio playback and recording for macOS
guests
* Audio: further timing improvements for Windows 10 guests
* Linux hosts: fixed problem accessing mini-toolbar under XFCE

Aside from just bumping the version number I also had to strip 3 levels
of the paths included in the guest-additions patches, because the
version was hardcoded in there and the patches still apply as-is.
I've re-added the stripped path using patchFlags and the -d option of
the patch utility.

Compiling the kernel modules on Linux 4.12 fails, so I've included an
upstream patch from:
https://www.virtualbox.org/changeset/66927/vbox
The patch is applied against the guest additions as well, where we need
to transform the patch a bit so that we get CR LF line endings (DOS
format), which is what is the case for the guest additions ISO.
I've tested this with all the subtests of the "virtualbox" NixOS VM
tests and they all succeed on x86_64-linux.

This commit contains security patches for xen 4.8. The patches
for XSA-216 applied to the kernel are omitted, as they are part of
80e0cda7ff.
XSA-216 Issue Description:
> The block interface response structure has some discontiguous fields.
> Certain backends populate the structure fields of an otherwise
> uninitialized instance of this structure on their stacks, leaking
> data through the (internal or trailing) padding field.

> Domains controlling other domains are permitted to map pages owned by
> the domain being controlled. If the controlling domain unmaps such a
> page without flushing the TLB, and if soon after the domain being
> controlled transfers this page to another PV domain (via
> GNTTABOP_transfer or, indirectly, XENMEM_exchange), and that third
> domain uses the page as a page table, the controlling domain will have
> write access to a live page table until the applicable TLB entry is

> * When a grant had been mapped twice by a backend domain, and then
> unmapped by two concurrent unmap calls, the frontend may be informed
> that the page had no further mappings when the first call completed rather
> than when the second call completed.

This commit adds the xen_4_8 package to be used instead of
xen (currently at 4.5.5):
* Add packages xen_4_8, xen_4_8-slim and xen_4_8-light
* Add packages qemu_xen_4_8 and qemu_xen_4_8-light to be used
with xen_4_8-slim and xen_4_8-light respectively.
* Add systemd to buildInputs of xen (it is required by oxenstored)
* Adapt xen service to work with the new version of xen
* Use xen-init-dom0 to initlilise dom0 in xen-store
* Currently, the virtualisation.xen.stored option is ignored
if xen 4.8 is used

The merge of the version bump in
6fb9f89238 didn't take care of our patch
for the hardening mode and thus enabling VirtualBox without also
force-disabling hardening mode will result in a build error.
While the patch is largely identical with the old version, I've removed
one particular change around the following code:
if (pFsObjState->Stat.st_mode & S_IWOTH)
return supR3HardenedSetError3(VERR_SUPLIB_WORLD_WRITABLE, pErrInfo,
"World writable: '", pszPath, "'");
In the old version of the patch we have checked whether the path is
within the Nix store and suppressed the error return if that's the case.
The reason why I did that in the first place was because we had a bunch
of symlinks which were writable.
In VirtualBox 5.1.22 the code specifically checks whether the file is a
symlink, so we can safely drop our change.
Tested via all of the "virtualbox" NixOS VM subtests and they now all
succeed.

XSA-211 Issue Description:
> When a graphics update command gets passed to the VGA emulator, there
> are 3 possible modes that can be used to update the display:
>
> * blank - Clears the display
> * text - Treats the display as showing text
> * graph - Treats the display as showing graphics
>
> After the display geometry gets changed (i.e., after the CIRRUS VGA
> emulation has resized the display), the VGA emulator will resize the
> console during the next update command. However, when a blank mode is
> also selected during an update, this resize doesn't happen. The resize
> will be properly handled during the next time a non-blank mode is
> selected during an update.
>
> However, other console components - such as the VNC emulation - will
> operate as though this resize had happened. When the display is
> resized to be larger than before, this can result in a heap overflow
> as console components will expect the display buffer to be larger than
> it is currently allocated.

XSA-213 Issue Description:

> context only, which certain hypercall handlers make assumptions on.
> The IRET hypercall (replacing the identically name CPU instruction)
> is used by guest kernels to transfer control from kernel mode to user
> mode. If such an IRET hypercall is placed in the middle of a multicall
> batch, subsequent operations invoked by the same multicall batch may
> wrongly assume the guest to still be in kernel mode. If one or more of
> these subsequent operations involve operations on page tables, they may
> be using the wrong root page table, confusing internal accounting. As

XSA-214 Issue Description:
> The GNTTABOP_transfer operation allows one guest to transfer a page to

>
> If the destination guest is a PV one of different bitness, it may gain
> access to segment descriptors it is not normally allowed to have, like
> 64-bit code segments in a 32-bit PV guest.
>
> If the destination guest is a HVM one, that guest may freely alter the
> page contents and then hand the page back to the same or another PV
> guest.
>
> In either case, if the destination PV guest then inserts that page into

XSA-215 Issue Description:

> selectors DS, ES, FS, and GS). Prior to placing exception or failsafe
> callback frames on the guest kernel stack, Xen checks the linear
> address range to not overlap with hypervisor space. The range spanned
> by that check was mistakenly not covering these extra 4 slots.

Recent commit #c10af9e744c91dff1ccc07a52a0b57d1e4d339f3 changed the
behaviour of wrapPythonPrograms, which caused pygrub to no longer
being wrapped. This commit fixes this.
- Moves to a more recent kernel (4.10, I think ...)
- API break re the previous version
- cptofs: fix root directory copy
- add support for disks with custom ops
- add LKL_HIJACK_NET_QDISC to configure qdisc policy
- add LKL_HIJACK_SYSCTL to configure sysctl values
OVMF{,CODE,VARS}.fd are now available in a dedicated fd output, greatly
reducing the closure in the common case where only those files are used (a
few MBs versus several hundred MBs for the full OVMF).
Note: it's unclear why `dontPatchELF` is now necessary for the build to
pass (on my end, at any rate) but it doesn't make much sense to run this
fixup anyway,
Note: my reading of xen's INSTALL suggests that --with-system-ovmf should
point directly to the OVMF binary. As such, the previous invocation was
incorrect (it pointed to the root of the OVMF tree). In any case, I have
only built xen with `--with-system-ovmf`, I have not tested it.
Fixes https://github.com/NixOS/nixpkgs/issues/25854
Closes https://github.com/NixOS/nixpkgs/pull/25855
OVMF is built from edk2 sources so that's where its version number comes
from (logically). The edk2 version number is 2014-12-10, so this change
only ensures the version numbers won't drift apart in the future. (There
is no hash change.)
