Fixed a number of issues that can cause Swarm encrypted overlay networks
to fail to uphold their guarantees, addressing CVE-2023-28841,
CVE-2023-28840, and
CVE-2023-28842.
A lack of kernel support for encrypted overlay networks now reports
as an error.
Encrypted overlay networks are eagerly set up, rather than waiting for
multiple nodes to attach.
Encrypted overlay networks are now usable on Red Hat Enterprise Linux 9
through the use of the xt_bpf kernel module.
Users of Swarm overlay networks should review GHSA-vwm3-crmr-xfxw
to ensure that unintentional exposure has not occurred.
Upgrade github.com/containerd/fifo to v1.1.0 to fix a potential panic moby/moby#45216.
Fix missing Bash completion for installed cli-plugins docker/cli#4091.
Fix an issue where docker build would fail when using --add-host=host.docker.internal:host-gateway
with BuildKit enabled moby/moby#44650.
Revert seccomp: block socket calls to AF_VSOCK in default profile moby/moby#44712.
This change, while favorable from a security standpoint, caused a change
in behavior for some use-cases. As such, we are reverting it to ensure
stability and compatibility for the affected users.
However, users of AF_VSOCK in containers should recognize that this
(special) address family is not currently namespaced in any version of
the Linux kernel, and may result in unexpected behavior, like containers
communicating directly with host hypervisors.
Future releases, will filter AF_VSOCK. Users who need to allow containers
to communicate over the unnamespaced AF_VSOCK will need to turn off seccomp
confinement or set a custom seccomp profile.
