"shared/nm-std-aux/unaligned.h" is taken from systemd and frequently
re-imported via the "systemd" branch.
It is not our code, and should not be formatted with our clang-format.
Alpine is especially interesting because it uses musl as libc.
The build does not yet succeed. There are several issues that
need to be fixed.
However, it will be simpler to fix things, if we have tests
in place -- even if at the moment they are known to be broken.

"find-backports" searches commit messages of upstream branches for
"Fixes:" comments. Those will then be highlighted to be backported,
if the script determines that to be necessary.
"find-backports" also honors the "cherry picked from" comments, to detect when
a patch was already backported. That is thus a way to suppress reporting a
commit to be backported.
Add another way to flag commits so they don't need backporting. Via
"Ignore-Backport:" tag.
As "find-backports" also honors "refs/notes/bugs" notes, this can be used
like:
git notes \
--ref refs/notes/bugs \
append \
-m "Ignore-Backport: e""29f00fa0c69 ('NEWS: fix entry that is targeted for 1.30 instead of 1.28')" \

The checkpatch test tests the patches on the merg-request, as they
branch off from master (or one of the stable branches).
It thus need the full git history, but the git repository might be a
shallow clone. Fix it.
We already build a large variety of configurations in gitlab-ci,
we don't need yet another configuration to run tests on travis-ci.
Also, because the travis-ci setup is outdated and we don't look
at it. Let's focus on gitlab-ci instead.
We use clang-format to format our code, and the exact format depends on
the clang version. Currently we use clang-11, as packaged in Fedora 33.
Add a script that runs a Fedora 33 container with podman and reformats
the current working directory.
Usage:
./contrib/scripts/nm-code-format-container.sh
Our new format gets enforced by clang-format, and we now only use
four space indentation, instead of tabs.
Adjust the checkpatch script to account for that.
Also, now there are probably no cases left where we want to see any
tabs in our sources. Complain about any tabs we find.
When opening a merge request from a fork of NetworkManager, then the
pipeline runs with the a checkout of the fork. That means, checkpatch
would compare the branch against "master" (or "nm-x-y" stable branches)
of the fork, instead of upstream.
That doesn't seem too useful. Instead, also add upstream NetworkManager
as git remote, fetch the branches, and use the branches from there as
base for checkpatch.

This is a one-off hacky tool that we'll use to convert the long license
boilerplates to SPDX headers that are more friendly to automated tools.
Then we can drop it and forget it existed.
This is inspired by the existing systemd integration, with a few differences:
* This parses the WPAD option, which systemd requested, but did not use.
* We hook into the DAD handling, only making use of the configured address
once DAD has completed successfully, and declining the lease if it fails.
There are still many areas of possible improvement. In particular, we need
to ensure the parsing of all options are compliant, as n-dhcp4 treats all
options as opaque, unlike sd-dhcp4. We probably also need to look at how
to handle failures and retries (in particular if we decline a lease).
We need to query the current MTU at client startu, as well as the hardware
broadcast address. Both these are provided by the kernel over netlink, so
it should simply be a matter of hooking that up with NM's netlink layer.
Contribution under LGPL2.0+, in addition to stated licenses.
In continations (that use spaces for alignment), don't allow the number
of leading tabs to change. Previously only removal of tabs was
disallowed, but addition doesn't make sense either, as only spaces
should be used for further alignemnt.
This catches situations like this:
|<-tab->all_work_and_no_play (makes,
|<-tab-> jack,
|<-tab-><-tab-> a dull boy);
The functionality of the ibft settings plugin is now handled by
nm-initrd-generator. There is no need for it anymore, drop it.
Note that ibft called iscsiadm, which requires CAP_SYS_ADMIN to work
([1]). We really want to drop this capability, so the current solution
of a settings plugin (as it is implemented) is wrong. The solution
instead is nm-initrd-generator.
Also, on Fedora the ibft was disabled and probably on most other
distributions as well. This was only used on RHEL.

We no longer add these. If you use Emacs, configure it yourself.
Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.
No manual changes, just ran commands:
F=($(git grep -l -e '-\*-'))
sed '1 { /\/\* *-\*- *[mM]ode.*\*\/$/d }' -i "${F[@]}"
sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"
Check remaining lines with:
git grep -e '-\*-'
The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.
It doesn't have to be at the end of line, there may be more words
following.

On Ubuntu 16.04 (trusty) valgrind fails due to rdrand being advertised
but not implemented.
Work around that by installing valgrind from Ubuntu 18.04 (bionic) via
the "contrib/scripts/nm-ci-install-valgrind-in-ubuntu1604.sh" script.
This removes libnm-glib, libnm-glib-vpn, and libnm-util for good.
The it has been replaced with libnm since NetworkManager 1.0, disabled
by default since 1.12 and no up-to-date distributions ship it for years
now.
Removing the libraries allows us to:
* Remove the horrible hacks that were in place to deal with accidental use
of both the new and old library in a single process.
* Relief the translators of maintenance burden of similar yet different
strings.
* Get rid of known bad code without chances of ever getting fixed
(libnm-glib/nm-object.c and libnm-glib/nm-object-cache.c)
* Generally lower the footprint of the releases and our workspace
If there are some really really legacy users; they can just build
libnm-glib and friends from the NetworkManager-1.16 distribution. The
D-Bus API is stable and old libnm-glib will keep working forever.

Enabling eBPF causes src/devices/tests/test-acd to fail:
strace: bpf(BPF_MAP_CREATE, {map_type=BPF_MAP_TYPE_HASH, key_size=4, value_size=1, max_entries=8, map_flags=0, inner_map_fd=0, map_name="", map_ifindex=0, btf_fd=0, btf_key_type_id=0, btf_value_type_id=0}, 112) = -1 EPERM (Operation not permitted)
NetworkManager-Message: 10:07:04.404: <warn> [1554631624.4046] acd[0xa2b400,10]: couldn't init ACD for announcing addresses on interface 'nm-test-veth0': Operation not permitted
Interestingly it does not always fail. Seems to depend on the kernel
which is used in the containerized test environments of gitlab-ci.
For now, just disable eBPF and use the fallback implementation.
