No IPAM IPv6 address is given to an interface in a network with
'--ipv6=false', but the kernel would assign a link-local address and,
in a macvlan/ipvlan network, the interface may get a SLAAC-assigned
address.
So, disable IPv6 on the interface to avoid that.

This reverts commit a77e147d32.
The ipvlan integration tests have been skipped in CI because of a check
intended to ensure the kernel has ipvlan support - which failed, but
seems to be unnecessary (probably because kernels have moved on).

We document that an macvlan network with no parent interface is
equivalent to a '--internal' network. But, in this case, an macvlan
network was still configured with a gateway. So, DNS proxying would
be enabled in the internal resolver (and, if the host's resolver
was on a localhost address, requests to external resolvers from the
host's network namespace would succeed).
This change disables configuration of a gateway for a macvlan Endpoint
if no parent interface is specified.
(Note if a parent interface with no external network is supplied as
'-o parent=<dummy>', the gateway will still be set up. Documentation
will need to be updated to note that '--internal' should be used to
prevent DNS request forwarding in this case.)

The internal DNS resolver should only forward requests to external
resolvers if the libnetwork.Sandbox served by the resolver has external
network access (so, no forwarding for '--internal' networks).
The test for external network access was whether the Sandbox had an
Endpoint with a gateway configured.
However, an ipvlan-l3 networks with external network access does not
have a gateway, it has a default route bound to an interface.
Also, we document that an ipvlan network with no parent interface is
equivalent to a '--internal' network. But, in this case, an ipvlan-l2
network was configured with a gateway. So, DNS proxying would be enabled
in the internal resolver (and, if the host's resolver was on a localhost
address, requests to external resolvers from the host's network
namespace would succeed).
So, this change adjusts the test for enabling DNS proxying to include
a check for '--internal' (as a shortcut) and, for non-internal networks,
checks for a default route as well as a gateway. It also disables
configuration of a gateway or a default route for an ipvlan Endpoint if
no parent interface is specified.
(Note if a parent interface with no external network is supplied as
'-o parent=<dummy>', the gateway/default route will still be set up
and external DNS proxying will be enabled. The network must be
configured as '--internal' to prevent that from happening.)

go1.21.9 (released 2024-04-03) includes a security fix to the net/http
package, as well as bug fixes to the linker, and the go/types and
net/http packages. See the [Go 1.21.9 milestone](https://github.com/golang/go/issues?q=milestone%3AGo1.21.9+label%3ACherryPickApproved)
for more details.
These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.

Partially reverts 0046b16 "daemon: set libnetwork sandbox key w/o OCI hook"
Running SetKey to store the OCI Sandbox key after task creation, rather
than from the OCI prestart hook, meant it happened after sysctl settings
were applied by the runtime - which was the intention, we wanted to
complete Sandbox configuration after IPv6 had been disabled by a sysctl
if that was going to happen.
But, it meant '--sysctl' options for a specfic network interface caused
container task creation to fail, because the interface is only moved into
the network namespace during SetKey.
This change restores the SetKey prestart hook, and regenerates config
files that depend on the container's support for IPv6 after the task has
been created. It also adds a regression test that makes sure it's possible
to set an interface-specfic sysctl.

The `identity.ChainIDs` call was accidentally removed in
b37ced2551.
This broke the shared size calculation for images with more than one
layer that were sharing the same compressed layer.
This was could be reproduced with:
```
$ docker pull docker.io/docker/desktop-kubernetes-coredns:v1.11.1
$ docker pull docker.io/docker/desktop-kubernetes-etcd:3.5.10-0
$ docker system df

After a535a65c4b the size reported by the
image list was changed to include all platforms of that image.
This made the "shared size" calculation consider all diff ids of all the
platforms available in the image which caused "snapshot not found"
errors when multiple images were sharing the same layer which wasn't
unpacked.

Benchmark the `Images` implementation (image list) against an image
store with 10, 100 and 1000 random images. Currently the images are
single-platform only.
The images are generated randomly, but a fixed seed is used so the
actual testing data will be the same across different executions.
Because the content store is not a real containerd image store but a
local implementation, a small delay (500us) is added to each content
store method call. This is to simulate a real-world usage where each
containerd client call requires a gRPC call.
