Impactful Client Updates
--------------------------------------------------------------------------------
This release has changes which may affect projects which import containerd.
*Switch to Go modules*
containerd and all containerd sub-repositories are now using Go modules. This
should help make importing easier for handling transitive dependencies. As of
this release, containerd still does not guarantee client library compatibility
for 1.x versions, although best effort is made to minimize impact from changes
to exported Go packages.
*CRI plugin moved to main repository*
With the CRI plugin moving into the main repository, imports under github.com/containerd/cri/
can now be found github.com/containerd/containerd/pkg/cri/.
There are no changes required for end users of CRI.
*Library changes*
oci
The WithAllCapabilities has been removed and replaced with WithAllCurrentCapabilities
and WithAllKnownCapabilities. WithAllKnownCapabilities has similar
functionality to the previous WithAllCapabilities with added support for newer
capabilities. WithAllCurrentCapabilities can be used to give privileged
containers the same set of permissions as the calling process, preventing errors
when privileged containers attempt to get more permissions than given to the
caller.
*Configuration changes*
New registry.config_path for CRI plugin
registry.config_path specifies a directory to look for registry hosts
configuration. When resolving an image name during pull operations, the CRI
plugin will look in the <registry.config_path>/<image hostname>/ directory
for host configuration. An optional hosts.toml file in that directory may be
used to configure which hosts will be used for the pull operation as well
host-specific configurations. Updates under that directory do not require
restarting the containerd daemon.
Enable registry.config_path in the containerd configuration file.
[plugins."io.containerd.grpc.v1.cri".registry]
config_path = "/etc/containerd/certs.d"
Configure registry hosts, such as /etc/containerd/certs.d/docker.io/hosts.toml
for any image under the docker.io namespace (any image on Docker Hub).
server = "https://registry-1.docker.io"
[host."https://public-mirror.example.com"]
capabilities = ["pull"]
[host."https://docker-mirror.internal"]
capabilities = ["pull", "resolve"]
ca = "docker-mirror.crt"
If no hosts.toml configuration exists in the host directory, it will fallback
to check certificate files based on Docker's certificate file
pattern (".crt" files for CA certificates and ".cert"/".key" files for client
certificates).
*Deprecation of registry.mirrors and registry.configs in CRI plugin*
Mirroring and TLS can now be configured using the new registry.config_path
option. Existing configurations may be migrated to new host directory
configuration. These fields are only deprecated with no planned removal,
however, these configurations cannot be used while registry.config_path is
defined.
*Version 1 schema is deprecated*
Version 2 of the containerd configuration toml is recommended format and the
default. Starting this version, a deprecation warning will be logged when
version 1 is used.
To check version, see the version value in the containerd toml configuration.
version=2
FreeBSD Runtime Support (Experimental)
--------------------------------------------------------------------------------
This release includes changes that allow containerd to run on FreeBSD with a
compatible runtime, such as runj. This
support should be considered experimental and currently there are no official
binary releases for FreeBSD. The runtimes used by containerd are maintained
separately and have their own stability guarantees. The containerd project
strives to be compatible with any runtime which aims to implement containerd's
shim API and OCI runtime specification.

The github.com/BurntSushi/toml project is no longer maintained,
and containerd is switching to this project instead, so start
moving our code as well.
This patch only changes the binary used during validation (tbh,
we could probably remove this validation step, but leaving that
for now).
I manually verified that the hack/verify/toml still works by adding a commit
that makes the MAINTAINERS file invalid;

- fixed IPv6 iptables rules for enabled firewalld (libnetwork#2609)
- fixes "Docker uses 'iptables' instead of 'ip6tables' for IPv6 NAT rule, crashes"
- Fix regression in docker-proxy
- introduced in "Fix IPv6 Port Forwarding for the Bridge Driver" (libnetwork#2604)
- fixes/addresses: "IPv4 and IPv6 addresses are not bound by default anymore" (libnetwork#2607)
- fixes/addresses "IPv6 is no longer proxied by default anymore" (moby#41858)
- Use hostIP to decide on Portmapper version
- fixes docker-proxy not being stopped correctly
Port mapping of containers now contain separatet mappings for IPv4 and IPv6 addresses, when
listening on "any" IP address. Various tests had to be updated to take multiple mappings into
account.

Since rootlesskit removed vendor folder, building it has to rely on go mod.
Dockerfile in docker-ce-packaging uses GOPROXY=direct, which makes "go mod"
commands use git to fetch modules. "go mod" in Go versions before 1.14.1 are
incompatible with older git versions, including the version of git that ships
with CentOS/RHEL 7 (which have git 1.8), see golang/go#38373
This patch switches rootlesskit install script to set GOPROXY to
https://proxy.golang.org so that git is not required for downloading modules.
Once all our code has upgraded to Go 1.14+, this workaround should be
removed.

Release notes for runc v1.0.0-rc93
-------------------------------------------------
This is the last feature-rich RC release and we are in a feature-freeze until
1.0. 1.0.0~rc94 will be released in a few weeks with minimal bug fixes only,
and 1.0.0 will be released soon afterwards.
- runc's cgroupv2 support is no longer considered experimental. It is now
believed to be fully ready for production deployments. In addition, runc's
cgroup code has been improved:
- The systemd cgroup driver has been improved to be more resilient and
handle more systemd properties correctly.
- We now make use of openat2(2) when possible to improve the security of
cgroup operations (in future runc will be wholesale ported to libpathrs to
get this protection in all codepaths).
- runc's mountinfo parsing code has been reworked significantly, making
container startup times significantly faster and less wasteful in general.
- runc now has special handling for seccomp profiles to avoid making new
syscalls unusable for glibc. This is done by installing a custom prefix to
all seccomp filters which returns -ENOSYS for syscalls that are newer than
any syscall in the profile (meaning they have a larger syscall number).
This should not cause any regressions (because previously users would simply
get -EPERM rather than -ENOSYS, and the rule applied above is the most
conservative rule possible) but please report any regressions you find as a
result of this change -- in particular, programs which have special fallback
code that is only run in the case of -EPERM.
- runc now supports the following new runtime-spec features:
- The umask of a container can now be specified.
- The new Linux 5.9 capabilities (CAP_PERFMON, CAP_BPF, and
CAP_CHECKPOINT_RESTORE) are now supported.
- The "unified" cgroup configuration option, which allows users to explicitly
specify the limits based on the cgroup file names rather than abstracting
them through OCI configuration. This is currently limited in scope to
cgroupv2.
- Various rootless containers improvements:
- runc will no longer cause conflicts if a user specifies a custom device
which conflicts with a user-configured device -- the user device takes
precedence.
- runc no longer panics if /sys/fs/cgroup is missing in rootless mode.
- runc --root is now always treated as local to the current working directory.
- The --no-pivot-root hardening was improved to handle nested mounts properly
(please note that we still strongly recommend that users do not use
--no-pivot-root -- it is still an insecure option).
- A large number of code cleanliness and other various cleanups, including
fairly large changes to our tests and CI to make them all run more
efficiently.
For packagers the following changes have been made which will have impact on
your packaging of runc:
- The "selinux" and "apparmor" buildtags have been removed, and now all runc
builds will have SELinux and AppArmor support enabled. Note that "seccomp"
is still optional (though we very highly recommend you enable it).
- make install DESTDIR= now functions correctly.

NOTE: the Dockerfile currently uses a single version of Golang for all
stages. This means that currently, all binaries are built with Go
1.13.x, including the containerd binary; upstream containerd switched
to use Go 1.15.

When using go modules, `go build` will always fetch the latest
version of the package, so ignores the version we previously `go get`'d.
Instead of running `go get` and `go build` separately, this patch uses
`go get` (without the `-d` option) to do it all in one step.
Given that this binary is only used for testing, and only used inside the
Dockerfile, we should consider inlining this step in the Dockerfile itself,
but keeping that separate for now.

Building gotestsum started to fail after the repository removed some
dependencies on master.
What happens is that first, we `go get` the package (with go modules disabled);
GO111MODULE=off go get -d gotest.tools/gotestsum
Which gets the latest version from master, and fetches the dependencies used
on master. Then we checkout the version we want to install (for example `v0.3.5`)
and run go build.
However, `v0.3.5` depends on logrus, and given that we ran `go get` for `master`,
that dependency was not fetched, and build fails.
This patch modifies the installer to use go modules (alternatively we could
probably run `go get .` after checking out the `v0.3.5` version),
We need to modify all installers, as it looks like this is a standard pattern
we use, but other dependencies were not failing (yet), so this patch only
addresses the immediate failure.
