go1.21.9 (released 2024-04-03) includes a security fix to the net/http
package, as well as bug fixes to the linker, and the go/types and
net/http packages. See the [Go 1.21.9 milestone](https://github.com/golang/go/issues?q=milestone%3AGo1.21.9+label%3ACherryPickApproved)
for more details.
These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.
Thanks to Bartek Nowotarski (https://nowotarski.info/) for reporting this issue.

This is better because every possible platform combination
does not need to be defined in the Dockerfile. If built
for platform where Delve is not supported then it is just
skipped.

Use a separate `devcontainer` Dockerfile target, this allows to include
the `gopls` in the devcontainer so it doesn't have to be installed by
the Go vscode extension.

=== Pasta ===
RootlessKit v2 adds the support for pasta (https://passt.top/passt/).
Pasta is similar to slirp4netns but its port forwarder achieves better
throughput than slirp4netns port driver.
It is still not faster than RootlessKit's `builtin` port driver, but unlike the
`builtin` port driver, pasta can retain source IP address information.
Network driver | Port driver | Net throughput | Port throughput | Src IP | No SUID | Note
---------------|----------------|----------------|-----------------|--------|---------|--------------------------------------------
slirp4netns | builtin | Slow | Fast ✅ | ❌ | ✅ | Default in typical setup
vpnkit | builtin | Slow | Fast ✅ | ❌ | ✅ | Default when slirp4netns is not installed
slirp4netns | slirp4netns | Slow | Slow | ✅ | ✅ |
**pasta** | **implicit** | Slow | Fast ✅ | ✅ | ✅ | Experimental
lxc-user-nic | builtin | Fast ✅ | Slow | ❌ | ❌ | Experimental
(bypass4netns) | (bypass4netns) | Fast ✅ | Fast ✅ | ✅ | ✅ | (Not integrated to RootlessKit)
=== Detach-netns ===
Aside from pasta, RootlessKit v2 also brings the support for
"detach-netns" mode, which leaves the runtime in the host network namespace to
eliminate the slirp overhead for pull/push and to allow accessing the "real"
127.0.0.1.
See containerd/nerdctl PR 2723 for how detach-netns is being adopted in
nerdctl v2.
Integrating detach-netns into Docker/Moby will need an extra work and will be
deferred to Docker v26 (or later).

Commit 0b1c1877c5 updated the version in
hack/dockerfile/install/rootlesskit.installer, but forgot to update the
version in Dockerfile.
Also updating both to use a tag, instead of commit. While it's good to pin by
an immutable reference, I think it's reasonably safe to use the tag, which is
easier to use, and what we do for other binaries, such as runc as well.

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.

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.
This is an update to CVE-2023-45283 and Go issue https://go.dev/issue/64028.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

Follow-up to e72c4818c4, which updated the
Dockerfile to use Debian 12 "bookworm", but forgot to update the package
repository to use for the CRIU packages. Note that the criu stage is currently
not built by default (see d3d2823edf), so to
verify the stage, it needs to be built manually;
docker build --target=criu .
This patch adds an extra `criu --version` to the build, so that it's verified
to be "functional".

This option was originally added in 8ec8564691,
at which time the upstream debian package repositories were not always
reliable, so using a mirror helped with CI stability and performance.
Debian's package repositories are a lot more reliable now, so there's no
longer a need to use a mirror.

We used DEBIAN_FRONTEND in some places to prevent installation of packages
from being blocked. However, debian bookworm now [includes a fix][1] for
situations like this (it was specifically reported for Docker situations <3),
so we can get rid of these.
Thanks to Tianon for noticing this, and for linking to the Debian ticket!
