Use the wrapper calls from Ia267a60eecfa8f4071dd477d86daebe07e9a7e38
to install glean.
Using this wrapper means we cover all cases without more and more
branches; it should work for python2, python3 and also the special
case of RHEL/CentOS where dib-python points to the special
/usr/libexec/platform-python (which is python3.6 with inbuilt pip)

NetworkManager with simple-init has proven to be stable in OpenStack
infra, switch to it by default for CentOS and Fedora. For CentOS 8
and Fedora, add a check to make it the only option. Thus only CenOS 7
remains optionally using the legacy scripts; this is likely not used
anywhere (infra is really the primary user, where NetworkManager is
already used); we can likely remove this variable (and hence path) in
a future cleanup.
In the setup, remove rhel7 element which was never really tested.
Reorganise the fallthrough to call out the default paths as doing
nothing.

Currently, the serial console is hardcoded to ttyS0 in the bootloader

As described inline, deprecate the "source" install for CentOS 8.
Overwriting the packaged tools has long been a pain-point in our
images, and the best outcome is just not to play the game [1].
However, the landscape remains complicated. For example, RHEL/CentOS
8 introduces the separate "platform-python" binary, which seems like
the right tool to install platform tools like "glean" (simple-init)
with. However, platform-python doesn't have virtualenv (only the
inbuilt venv).
So that every element doesn't have to hard-code in workarounds for
these various layouts, create two new variables DIB_PYTHON_PIP and
DIB_PYTHON_VIRTUALENV to just "do the right thing". If you need is
"install a pip package" or "create a virtualenv" this should work on
all the platforms we support. If you know more specifically what you
want (e.g. must be a python3 virtualenv) then nothing stops elements
calling that directly (e.g. python3 -m virtualenv create); these are
just helper wrappers for base elements that need to be broadly
compatible.

Install the Python 3 libselinux packages for Fedora platforms. I
think this is the right choice; Fedora is a Python-3 only distro so we
shouldn't default to installing the python2 libraries.
This has a practical effect if you're using Ansible with
ansible_python_interpreter=/usr/bin/python3 as it needs these
packages.
There is some small chance of breakage if you're using Ansible still
with Python 2, I guess. In infra I notice we bring this in with
"zuul-worker" project-config element. On balance, I think that if you
need the Python 2 packages for some reason, it should be a special
install and not part of redhat-common.

Two bugs are addressed.
1) The sysprep element was broken in that it only truncates
/etc/machine-id, but not /var/lib/dbus/machine-id. systemd will
not generate a new machine-id if /var/lib/dbus/machine-id is
present[1], it will simply copy it to /etc/machine-id.
We observed machine-ids being packaged in /var/lib/dbus/machine-id
on several distros: Ubuntu Bionic, Fedora 29, Debian Stretch.
CentOS 7 and Ubuntu Xenial do not contain packaged machine-id as
far as I can tell.
All test builds were performed using -minimal elements.
2) A second bug existed where debian-minimal did not run the sysprep
element at all, so a stretch image I tested contained a populated
/etc/machine-id AND a populated /var/lib/dbus/machine-id.

linux-firmware and linux-firmware-whence (meta package for mostly iwl
firmwares) packages account for approx. 289 M install size on a F30
system, and linux-firmware for approx. 176 M on CentOS 7. Users needing
these firmwares are eventually baremetal users and are not looking for a
very minimal operating system base install like virtual image users are.
Thus, a non-minimal OS element is better suited for them. Alternatively,
it could be later considered a dedicated firmware element.

This is a follow-on to I475a253091cbaf63687b91c748c31a6753bb0f57 as we
are still seeing issues on some clouds with unconfigured networking.
We increase the timeout, but also make it configurable so we can
fiddle it without a dib release in the gate.
To follow-on from the experimentation done by clarkb, I can confirm by
emperical testing on a Centos 7 image (from today, today being this
change's date) that setting
net.ipv6.conf.all.autoconf=0
by itself is "fatal" and the interfaces do not come up; i.e. nm does
not by default seem to re-enable ipv6 for the interface. However,
explicitly adding:
IPV6INIT=yes
IPV6_AUTOCONF=yes
to the interface file *does* seem to make it work, even if
"all.autoconf=0" is set (then again, there's also bugs about the
effect of this [1]). However, no extant distribution (I can currently
find) does anything like this by default.
If this continues, this may be an option. Another might be to avoid
the use of the nm-settings-ifcfg-rh profiles and move directly to nm
ini files with glean.

Something (possibly [1], but that change is at best cryptic) has

Installing the -cloud release package gets it back, and seems like a

As noted in the change, 7fd52ba841
increased the size of the EFI partition considerably. This has meant
that our padding upwards of the disk size is insufficient and EFI
builds (arm64 in particular) is failing due to out-of-disk errors
during final image operations like installing kernels.
Similar to the discussion we had in
I65fa13a088eecdfe61636678578577ea2cfb3c0c, this feels a bit ugly
because we're mixing logic here with sizes specified in block-device
config files. But it boils down to the same problem; we are
calculating the disk size here and passing it to the block-layer, so
unless we want to make large changes to the status quo about where
these sizes are calculated, small adjustments here are the most KISS
solution.
Thus we check if we have selected the EFI bootloader element, and thus
assume there will be a large system EFI partition and expand the disk
size accordingly.

The linux kernel and NetworkManager fight each other over control for
interface management when router advertisements are in use. Long story
short if the linux kernel configures a network interface for ipv6
before NetworkManager attempts to manage that interface then NM will
ignore the interface and not configure ipv4 on it.
This can happen because the kernel is configured to send router
advertisements solicitations which result in router advertisements which
the kernel uses to configure the interface(s). There is a default of a 1
second delay before sending the solicitation which in many cases is long
enough that NM has started before then. However, in slower environments
like those used for testing with qemu this isn't long enough.
Some testing by hand indicates that 15 seconds is about right so
increase the delay to 15 seconds via sysctl.conf.
Note this may increase boot times in ipv6 only environments (though it
is hard to be sure due to how systemd starts everything at once and does
socket activation and the like).

I want to use the new --image-extra-size flag[1] but my use-case
calls for megabyte granularity of this value. Rather than adding
60% to an 800MB image, maybe I only want to add 100 or 200MB, etc.

Use openSUSE 15.0 as default, which is the latest released stable
openSUSE release. Switch to https for accessing download.o.org
as encrypted transfers should be used by default.
Remove leftovers for definitely unmaintained openSUSE 13.x images
and split into old/new leap style versioning scheme for clarity.

It looks like fedora-release on fedora 30+ has been split into sub
packages. Use fedora-release-common to avoid package conflicts.

Depending on the version of $DIB_PYTHON_VERSION, we can either use pip /
pip3 to install glean. This is helpful for newer OSes that might not
want to ship python2 (pip).

Currently diskimage-builder supports two ways to specify the image
size. One is defining a fixed image size using DIB_IMAGE_SIZE, the
other one is auto-detection while adding a security margin of 60% as
free space. This means when building larger images (e.g. >100GB) with
unknown size upfront we end up with much wasted space, IO and network
traffic when uploading the images to several cloud providers. This can
be optimized by adding a third way by defining DIB_IMAGE_EXTRA_SIZE to
specify the free space in GB. This makes it possible to easily build
images of varying sizes while still minimizing the overhead by keeping
the free space constant to e.g. 1GB.

In many cases, the statically sized 64MB journal is far below the
e2fstools default calculation[0] which calls for a 64MB journal only
on filesystems smaller than 16GB. On bare metal in particular, the
correct default journal size will often be in the 512MB-1GB range.
Since we cannot know what the target system is, this should be a
tunable parameter that the user can set depending on the intended
image usage.
Add a DIB_JOURNAL_SIZE envvar and --mkfs-journal-size parameter
to the image creation so users can override the default journal
size.

Due to the referenced bug, many versions of debootstrap can't bring up
a buster environment. Unfortunately, these include versions we use to
do this on Xenial/Bionic nodes.
Also, there isn't backports or security updates, so elide these for
now.
I did get a working build (I haven't gone so far as a full boot+glean)
with this, at least.

Paritial-Bug: #1822927
Currently, the cleanup script is using the existence of the folder
/sys/fs/selinux to check if SELinux is enabled. This, however, is
misleading in case disk-image-builder is used inside a Docker
container on a selinux-enabled host. In this case, the folder exists
in the container but SELinux is disabled.
This patch addresses the problem by checking, in addition to the
check already in place, the output of the command selinuxenabled.

Closes-Bug: #1820077
This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.
This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.
This update should result in no functional change.

This is only one line, but it takes a lot to untangle ... basically
the current "correct" path is:
---
mk_build_dir()
-> sets trap trap_cleanup EXIT
... stuff ..
mount_proc_dev_sys
-> mounts $TMP_MOUNT_PATH/<proc,dev.sysfs>
pre-finalise.d
finalise.d
unmount_image $TMP_BUILD_DIR/mnt # nb == $TMP_MOUNT_PATH
-> unmount_dir()
-> recursive unmount everything inside TMP_MOUNT_PATH
TMP_IMAGE_PATH=$(dib-block-device getval image-path)
export TMP_IMAGE_PATH
dib-block-device umount
dib-block-device cleanup
... actually cleanup directories ...
---
Our current failure exit trap does:
---
dib-block-device umount
unmount_image
...
---
Note this is the *opposite* of what is done in the correct exit path.
In the failure case, if a script fails in the finalise stages it leads
to /proc, /sys, /dev etc. still being mounted inside the image; the
"dib-block-device umount" call doesn't know anything about these
mounts and tries to unmount the parent directory, and we get a hard
failure with a busy mount, and all the mounts are subsequently leaked.
Note that "unmount_dir", which is ultimately called by
"unmount_image", already knows to skip those mounts that
"dib-block-device umount" manages (this is the DIB_MOUNTPOINTS list).
This is further evidence it should be called *before* the
dib-block-device umount.

Add a DIB_APT_MINIMAL_CREATE_INTERFACES boolean to the debootstrap
element which functions identically to
DIB_YUM_MINIMAL_CREATE_INTERFACES in the yum-minimal element.
This can be used to disable the creation of the
/etc/network/interfaces.d/eth[01] dhcp configuration files, which
are not needed on systems where cloud-init or other means are used
to configure networking.
The flag is enabled by default to keep creating the dhcp interface
files, maintaining backwards compatibility.

in same cases it is required to avoid update all existing packages,
doing so can result in release update which is currently not possible
unless you not include "base" element.
"base" element used for most distribution (rhel, debain), and is
necessary for most cloud operations, this patch add
"DIB_AVOID_PACKAGES_UPDATE" parameter to skip updating all packages.
usecases for this patch can be:
* Avoid release update when building old release ex. RHEL7.5.
* build on network-less environment.
usage:
DIB_AVOID_PACKAGES_UPDATE=1
or
DIB_AVOID_PACKAGES_UPDATE=0

Related to I041a141366099093805e6052b1bbf64efd277e1e, we also need to
remove this on opensuse. The files for gate testing are added, but
the test is not added to any jobs at this point in the interests of
gate time.
