This is the fifth patch release in the 1.2.z series of runc. It
primarily fixes an issue caused by an upstream systemd bug.
There was a regression in systemd v230 which made the way we define device
rule restrictions require a systemctl daemon-reload for our transient
units. This caused issues for workloads using NVIDIA GPUs. Workaround the
upstream regression by re-arranging how the unit properties are defined.
Dependency github.com/cyphar/filepath-securejoin is updated to v0.4.1,
to allow projects that vendor runc to bump it as well.
CI: fixed criu-dev compilation.
Dependency golang.org/x/net is updated to 0.33.0.

This is the fourth patch release of the 1.2.z release branch of runc. It
includes a fix for a regression introduced in 1.2.0 related to the
default device list.
- Re-add tun/tap devices to built-in allowed devices lists.
In runc 1.2.0 we removed these devices from the default allow-list
(which were added seemingly by accident early in Docker's history) as
a precaution in order to try to reduce the attack surface of device
inodes available to most containers. At the time we thought
that the vast majority of users using tun/tap would already be
specifying what devices they need (such as by using --device with
Docker/Podman) as opposed to doing the mknod manually, and thus
there would've been no user-visible change.
Unfortunately, it seems that this regressed a noticeable number of
users (and not all higher-level tools provide easy ways to specify
devices to allow) and so this change needed to be reverted. Users
that do not need these devices are recommended to explicitly disable
them by adding deny rules in their container configuration.

This is the third patch release of the 1.2.z release branch of runc. It
primarily fixes some minor regressions introduced in 1.2.0.
- Fixed a regression in use of securejoin.MkdirAll, where multiple
runc processes racing to create the same mountpoint in a shared rootfs
would result in spurious EEXIST errors. In particular, this regression
caused issues with BuildKit.
- Fixed a regression in eBPF support for pre-5.6 kernels after upgrading
Cilium's eBPF library version to 0.16 in runc.

This reverts commit f0f1bfca07.
runc 1.1.15 appears to have incresed chances for causing OOMs for
containers with small memory limits. Revert the change in containerd
to unblock CI while the upstream runc issue is resolved.

Release notes:
- The -ENOSYS seccomp stub is now always generated for the native
architecture that runc is running on. This is needed to work around some
arguably specification-incompliant behaviour from Docker on architectures
such as ppc64le, where the allowed architecture list is set to null. This
ensures that we always generate at least one -ENOSYS stub for the native
architecture even with these weird configs. (#4391)
- On a system with older kernel, reading /proc/self/mountinfo may skip some
entries, as a consequence runc may not properly set mount propagation,
causing container mounts leak onto the host mount namespace. (#2404, #4425)
- In order to fix performance issues in the "lightweight" bindfd protection
against [CVE-2019-5736], the temporary ro bind-mount of /proc/self/exe
has been removed. runc now creates a binary copy in all cases. (#4392, #2532)

- 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.

This is the seventh patch release in the 1.1.z release of runc, and is
the last planned release of the 1.1.z series. It contains a fix for
cgroup device rules with systemd when handling device rules for devices
that don't exist (though for devices whose drivers don't correctly
register themselves in the kernel -- such as the NVIDIA devices -- the
full fix only works with systemd v240+).
- When used with systemd v240+, systemd cgroup drivers no longer skip
DeviceAllow rules if the device does not exist (a regression introduced
in runc 1.1.3). This fix also reverts the workaround added in runc 1.1.5,
removing an extra warning emitted by runc run/start.
- The source code now has a new file, runc.keyring, which contains the keys
used to sign runc releases.

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 third release of the 1.1.z series of runc, and contains
various minor improvements and bugfixes.
- Our seccomp `-ENOSYS` stub now correctly handles multiplexed syscalls on
s390 and s390x. This solves the issue where syscalls the host kernel did not
support would return `-EPERM` despite the existence of the `-ENOSYS` stub
code (this was due to how s390x does syscall multiplexing).
- Retry on dbus disconnect logic in libcontainer/cgroups/systemd now works as
intended; this fix does not affect runc binary itself but is important for
libcontainer users such as Kubernetes.
- Inability to compile with recent clang due to an issue with duplicate
constants in libseccomp-golang.
- When using systemd cgroup driver, skip adding device paths that don't exist,
to stop systemd from emitting warnings about those paths.
- Socket activation was failing when more than 3 sockets were used.
- Various CI fixes.
- Allow to bind mount `/proc/sys/kernel/ns_last_pid` to inside container.
- runc static binaries are now linked against libseccomp v2.5.4.

This is the second patch release of the runc 1.1 release branch. It
fixes CVE-2022-29162, a minor security issue (which appears to not be
exploitable) related to process capabilities.
This is a similar bug to the ones found and fixed in Docker and
containerd recently (CVE-2022-24769).
- A bug was found in runc where runc exec --cap executed processes with
non-empty inheritable Linux process capabilities, creating an atypical Linux
environment. For more information, see GHSA-f3fp-gc8g-vw66 and CVE-2022-29162.
- runc spec no longer sets any inheritable capabilities in the created
example OCI spec (config.json) file.

This moves the runc version to build to scripts/setup/runc-version,
which makes it easier for packagers to find the default version
to use.
The RUNC_VERSION environment variable can still be used to override
the version, which can be used (e.g.) to test against different versions
in our CI.
