The DirCopy() function in "graphdriver/copy/copy.go" has a special case for
skip file-attribute copying when making a hard link to an already-copied
file, if "copyMode == Hardlink". Do the same for copies of hard-links in
the source filesystem.
Significantly speeds up vfs's copy of a BusyBox filesystem (which
consists mainly of hard links to a single binary), making moby's
integration tests run more quickly and more reliably in a dev container.

- full diff: https://github.com/opencontainers/runc/compare/v1.1.9...v1.1.10
- release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.10
This is the tenth (and most likely final) patch release in the 1.1.z
release branch of runc. It mainly fixes a few issues in cgroups, and a
umask-related issue in tmpcopyup.
- Add support for `hugetlb.<pagesize>.rsvd` limiting and accounting.
Fixes the issue of postgres failing when hugepage limits are set.
- Fixed permissions of a newly created directories to not depend on the value
of umask in tmpcopyup feature implementation.
- libcontainer: cgroup v1 GetStats now ignores missing `kmem.limit_in_bytes`
(fixes the compatibility with Linux kernel 6.1+).
- Fix a semi-arbitrary cgroup write bug when given a malicious hugetlb
configuration. This issue is not a security issue because it requires a
malicious config.json, which is outside of our threat model.

Use a strong type for the DNS IP-addresses so that we can use flags.IPSliceVar,
instead of implementing our own option-type and validation.
Behavior should be the same, although error-messages have slightly changed:
Before this patch:
dockerd --dns 1.1.1.1oooo --validate
Status: invalid argument "1.1.1.1oooo" for "--dns" flag: 1.1.1.1oooo is not an ip address
See 'dockerd --help'., Code: 125
cat /etc/docker/daemon.json
{"dns": ["1.1.1.1"]}
dockerd --dns 2.2.2.2 --validate
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: dns: (from flag: [2.2.2.2], from file: [1.1.1.1])
cat /etc/docker/daemon.json
{"dns": ["1.1.1.1oooo"]}
dockerd --validate
unable to configure the Docker daemon with file /etc/docker/daemon.json: merged configuration validation from file and command line flags failed: 1.1.1.1ooooo is not an ip address
With this patch:
dockerd --dns 1.1.1.1oooo --validate
Status: invalid argument "1.1.1.1oooo" for "--dns" flag: invalid string being converted to IP address: 1.1.1.1oooo
See 'dockerd --help'., Code: 125

- document accepted values
- add test-coverage for the function's behavior (including whitespace handling),
and use sub-tests.
- improve error-message to use uppercase for "IP", and to use a common prefix.

The forwarding database (fdb) of Linux VXLAN links are restricted to
entries with destination VXLAN tunnel endpoint (VTEP) address of a
single address family. Which address family is permitted is set when the
link is created and cannot be modified. The overlay network driver
creates VXLAN links such that the kernel only allows fdb entries to be
created with IPv4 destination VTEP addresses. If the Swarm is configured
with IPv6 advertise addresses, creating fdb entries for remote peers
fails with EAFNOSUPPORT (address family not supported by protocol).
Make overlay networks functional over IPv6 transport by configuring the
VXLAN links for IPv6 VTEPs if the local node's advertise address is an
IPv6 address. Make encrypted overlay networks secure over IPv6 transport
by applying the iptables rules to the ip6tables when appropriate.

This test broke in 98323ac114.
This commit renamed WithMacAddress into WithContainerWideMacAddress.
This helper sets the MacAddress field in container.Config. However, API
v1.44 now ignores this field if the NetworkMode has no matching entry in
EndpointsConfig.
This fix uses the helper WithMacAddress and specify for which
EndpointConfig the MacAddress is specified.

Change the non-refcounted implementation to perform the mount using the
same identity and access right. They should be the same regardless if
we're refcounting or not.
This also allows to refactor refCountMounter into a mounter decorator.
