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.

This is the fifth patch release in the 1.1.z series of runc, which fixes
three CVEs found in runc.
* CVE-2023-25809 is a vulnerability involving rootless containers where
(under specific configurations), the container would have write access
to the /sys/fs/cgroup/user.slice/... cgroup hierarchy. No other
hierarchies on the host were affected. This vulnerability was
discovered by Akihiro Suda.
<https://github.com/opencontainers/runc/security/advisories/GHSA-m8cg-xc2p-r3fc>
* CVE-2023-27561 was a regression which effectively re-introduced
CVE-2019-19921. This bug was present from v1.0.0-rc95 to v1.1.4. This
regression was discovered by @Beuc.
<https://github.com/advisories/GHSA-vpvm-3wq2-2wvm>
* CVE-2023-28642 is a variant of CVE-2023-27561 and was fixed by the same
patch. This variant of the above vulnerability was reported by Lei
Wang.
<https://github.com/opencontainers/runc/security/advisories/GHSA-g2j6-57v7-gm8c>
In addition, the following other fixes are included in this release:
* Fix the inability to use `/dev/null` when inside a container.
* Fix changing the ownership of host's `/dev/null` caused by fd redirection
(a regression in 1.1.1).
* Fix rare runc exec/enter unshare error on older kernels, including
CentOS < 7.7.
* nsexec: Check for errors in `write_log()`.

Allow SetMatrix to be used as a value type with a ready-to-use zero
value. SetMatrix values are already non-copyable by virtue of having a
mutex field so there is no harm in allowing non-pointer values to be
used as local variables or struct fields. Any attempts to pass around
by-value copies, e.g. as function arguments, will be flagged by go vet.

In preparation for containerd v1.7 which migrates off gogo/protobuf
and changes the protobuf Any type to one that's not supported by our
vendored version of typeurl.
This fixes a compile error on usages of `typeurl.UnmarshalAny` when
upgrading to containerd v1.7.

- Only use the image exporter in build if we don't use containerd
Without this "docker build" fails with:
Error response from daemon: exporter "image" could not be found
- let buildx know we support containerd snapshotter
- Pass the current snapshotter to the buildkit worker
If buildkit uses a different snapshotter we can't list the images any
more because we can't find the snapshot.
builder/builder-next: make ContainerdWorker a minimal wrapper
Note that this makes "Worker" a public field, so technically one could
overwrite it.
builder-next: reenable runc executor
Currently, without special CNI config the builder would
only create host network containers that is a security issue.
Using runc directly instead of shim is faster as well
as builder doesn’t need anything from shim. The overhead
of setting up network sandbox is much slower of course.
builder/builder-next: simplify options handling
Trying to simplify the logic;
- Use an early return if multiple outputs are provided
- Only construct the list of tags if we're using an image (or moby) exporter
- Combine some logic for snapshotter and non-snapshotter handling
Create a constant for the moby exporter
Pass a context when creating a router
The context has a 10 seconds timeout which should be more than enough to
get the answer from containerd.

...for limiting concurrent external DNS requests with
"golang.org/x/sync/semaphore".Weighted. Replace the ad-hoc rate limiter
for when the concurrency limit is hit (which contains a data-race bug)
with "golang.org/x/time/rate".Sometimes.
Immediately retrying with the next server if the concurrency limit has
been hit just further compounds the problem. Wait on the semaphore and
refuse the query if it could not be acquired in a reasonable amount of
time.

This addresses the same CVE as is patched in go1.19.6. From that announcement:
> net/http: avoid quadratic complexity in HPACK decoding
>
> A maliciously crafted HTTP/2 stream could cause excessive CPU consumption
> in the HPACK decoder, sufficient to cause a denial of service from a small
> number of small requests.
>
> This issue is also fixed in golang.org/x/net/http2 v0.7.0, for users manually
> configuring HTTP/2.
>
> This is CVE-2022-41723 and Go issue https://go.dev/issue/57855.
