In versions of Docker before v1.10, this field was calculated from
the image itself and all of its parent images. Images are now stored
self-contained, and no longer use a parent-chain, making this field
an equivalent of the Size field.

For the containerd integration, the Size should be the sum of the
image's compressed / packaged and unpacked (snapshots) layers.

This commit removes iptables rules configured for secure overlay
networks when a network is deleted. Prior to this commit, only
CreateNetwork() was taking care of removing stale iptables rules.
If one of the iptables rule can't be removed, the erorr is logged but
it doesn't prevent network deletion.

There's still some locations refering to AuFS;
- pkg/archive: I suspect most of that code is because the whiteout-files
are modelled after aufs (but possibly some code is only relevant to
images created with AuFS as storage driver; to be looked into).
- contrib/apparmor/template: likely some rules can be removed
- contrib/dockerize-disk.sh: very old contribution, and unlikely used
by anyone, but perhaps could be updated if we want to (or just removed).

Update the version manually (we don't have automation for this yet), and
add a comment to vendor.mod to help users remind to update it.

In the case of an error when calling snapshotter.Prepare we would return
nil. This change fixes that and returns the error from Prepare all the
time.

It's not originally supported by image list, but we need it for `prune`
needs it, so `list` gets it for free.

release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.6
full diff: https://github.com/opencontainers/runc/compare/v1.1.5...v1.1.6
This is the sixth patch release in the 1.1.z series of runc, which fixes
a series of cgroup-related issues.
Note that this release can no longer be built from sources using Go
1.16. Using a latest maintained Go 1.20.x or Go 1.19.x release is
recommended. Go 1.17 can still be used.
- systemd cgroup v1 and v2 drivers were deliberately ignoring UnitExist error
from systemd while trying to create a systemd unit, which in some scenarios
may result in a container not being added to the proper systemd unit and
cgroup.
- systemd cgroup v2 driver was incorrectly translating cpuset range from spec's
resources.cpu.cpus to systemd unit property (AllowedCPUs) in case of more
than 8 CPUs, resulting in the wrong AllowedCPUs setting.
- systemd cgroup v1 driver was prefixing container's cgroup path with the path
of PID 1 cgroup, resulting in inability to place PID 1 in a non-root cgroup.
- runc run/start may return "permission denied" error when starting a rootless
container when the file to be executed does not have executable bit set for
the user, not taking the CAP_DAC_OVERRIDE capability into account. This is
a regression in runc 1.1.4, as well as in Go 1.20 and 1.20.1
- cgroup v1 drivers are now aware of misc controller.

Change return value in function signature and return fatal errors so
they can actually be reported to the caller instead of just being logged
to daemon log.

The `oom-score-adjust` option was added in a894aec8d8,
to prevent the daemon from being OOM-killed before other processes. This
option was mostly added as a "convenience", as running the daemon as a
systemd unit was not yet common.
Having the daemon set its own limits is not best-practice, and something
better handled by the process-manager starting the daemon.
Commit cf7a5be0f2 fixed this option to allow
disabling it, and 2b8e68ef06 removed the default
score adjust.
This patch deprecates the option altogether, recommending users to set these
limits through the process manager used, such as the "OOMScoreAdjust" option
in systemd units.
With this patch:
dockerd --oom-score-adjust=-500 --validate
Flag --oom-score-adjust has been deprecated, and will be removed in the next release.

The call to an unsecure registry doesn't return an error saying that the
"server gave an HTTP response to an HTTPS client" but a
tls.RecordHeaderError saying that the "first record does not look like a
TLS handshake", this changeset looks for the right error for that case.
This fixes the http fallback when using an insecure registry

The (*network).ipamRelease function nils out the network's IPAM info
fields, putting the network struct into an inconsistent state. The
network-restore startup code panics if it tries to restore a network
from a struct which has fewer IPAM config entries than IPAM info
entries. Therefore (*network).delete contains a critical section: by
persisting the network to the store after ipamRelease(), the datastore
will contain an inconsistent network until the deletion operation
completes and finishes deleting the network from the datastore. If for
any reason the deletion operation is interrupted between ipamRelease()
and deleteFromStore(), the daemon will crash on startup when it tries to
restore the network.
Updating the datastore after releasing the network's IPAM pools may have
served a purpose in the past, when a global datastore was used for
intra-cluster communication and the IPAM allocator had persistent global
state, but nowadays there is no global datastore and the IPAM allocator
has no persistent state whatsoever. Remove the vestigial datastore
update as it is no longer necessary and only serves to cause problems.
If the network deletion is interrupted before the network is deleted
from the datastore, the deletion will resume during the next daemon
startup, including releasing the IPAM pools.
