This is the eleventh patch release in the 1.1.z release branch of runc.
It primarily fixes a few issues with runc's handling of containers that
are configured to join existing user namespaces, as well as improvements
to cgroupv2 support.
- Fix several issues with userns path handling.
- Support memory.peak and memory.swap.peak in cgroups v2.
Add swapOnlyUsage in MemoryStats. This field reports swap-only usage.
For cgroupv1, Usage and Failcnt are set by subtracting memory usage
from memory+swap usage. For cgroupv2, Usage, Limit, and MaxUsage
are set.
- build(deps): bump github.com/cyphar/filepath-securejoin.

The 0.11 branch of buildkit defaults to go1.19 (EOL), and
Alpine 3.17 (EOL).
We already set GO_VERSION to override the go version to
use go1.20, but the Dockerfile also has a ALPINE_VERSION
build-arg, so let's override that as well to prevent the
build from failing:

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.

update the dependency to v0.2.4 to prevent scanners from flagging the
vulnerability (GHSA-6xv5-86q9-7xr8 / GO-2023-2048). Note that that vulnerability
only affects Windows, and is currently only used in runc/libcontainer, so should
not impact our use (as that code is Linux-only).

This fixes the same CVE as go1.21.3 and go1.20.10;
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.
This is also tracked by CVE-2023-44487.

term: remove interrupt handler on termios
On termios platforms, interrupt signals are not generated in raw mode
terminals as the ISIG setting is not enabled. Remove interrupt handler
as it does nothing for raw mode and prevents other uses of INT signal
with this library.
This code seems to go back all the way to moby/moby#214 where signal
handling was improved for monolithic docker repository. Raw mode -ISIG
got reintroduced in moby/moby@3f63b87807, but the INT handler was left
behind.

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.

full diff: https://github.com/opencontainers/runc/compare/v1.1.5...v1.1.6
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.
