Fix: once the rootfs has been unmounted and crun's own state removed, remove the bundle directory too.

This is what lets nerdbox be used as a real CRI RuntimeClass handler via containerd's built-in shim sandboxer (sandboxer = "shim"). ## SandboxService (internal/shim/sandbox/service.go, new) Implements TTRPCSandboxService: CreateSandbox/StartSandbox — boots the VM with resources/networking derived from the sandbox bundle via a StartOptionsFunc callback registered by the task plugin, avoiding a circular import between the sandbox and task packages — StopSandbox/ShutdownSandbox, SandboxStatus (reporting the CRI v1 PodSandboxState enum's exact "SANDBOX_READY"/"SANDBOX_NOTREADY" names, not an invented vocabulary, since containerd's CRI layer derives PodSandboxStatus.State by looking the string up in that enum's name-to-value map), Platform, and Ping. Also owns pinning the sandbox's host-side network namespace for the VM's lifetime (internal/shim/sandbox/networksandbox.go, _linux/_other.go) and threading it down to libkrun: internal/vm/libkrun serializes every FFI call for a VM context onto one dedicated, permanently OS-thread-locked goroutine (vmExecutor), which is required for correct namespace scoping — entering a network namespace via setns(2) only affects the calling thread, and without a dedicated thread the Go scheduler could run different krun_* calls (and the worker threads libkrun spawns from them) in different namespaces. SetNetnsPath enters the namespace on that thread before any other configuration call. This ensures every container in the sandbox actually uses the CNI-assigned network the sandbox was created with, which is foundational regardless of any other pod feature. ## SharedFS (internal/shim/sandbox/sharedfs.go, new) Member-container rootfs assembly happens entirely on the host: each container's rootfs is assembled (overlay/erofs mounts, using nerdbox's own internal/mountutil.All rather than the generic vendored mount.All, which rejects nerdbox's custom "X-containerd.mkdir.*" options) inside a per-sandbox directory tree exposed to the guest over a single, persistent, pre-boot virtiofs share — avoiding the need to hot-add a virtiofs device per container, which libkrun does not support. ## Task service wiring (internal/shim/task/service.go) Task.Create now branches on whether the sandbox API is in use (IsSandboxed()): createSandboxedContainer resolves the rootfs via SharedFS and drives the already-running VM's guest bundle/mount/task RPCs directly, instead of createLegacyContainer's existing boot-a-fresh-VM-per-container path (preserved unchanged for non-sandboxed use). The per-sandbox VM event stream is now started exactly once (eventStreamOnce) regardless of how many member containers are created. internal/shim/task/socketforward.go gains CreateRootfsPlaceholders, needed because a sandboxed container's source rootfs must have UDS bind-mount placeholder files created before SharedFS's read-only share is assembled (the legacy path's rootfs isn't shared the same way, so this was never needed there). ## Plugin wiring plugins/shim/sandbox: the SandboxPlugin now wraps the raw VM-backed Sandbox in a SandboxService, exposed via a dedicated TTRPCPlugin "sandbox" (service_plugin.go) rather than the SandboxPlugin itself, to avoid a double-registration panic when the shim framework looks for TTRPCService implementors. plugins/shim/task wires the task plugin's NewTaskService to the same SandboxService instance and registers its StartOptionsFunc callback. ## Guest side pkg/vminit/initd/containers_mount_linux.go mounts the sandbox's shared virtiofs tree at /run/containers at vminitd startup (best-effort: absent/no-op on the legacy path, where the "containers" tag is never registered by the host). initd.go also raises RLIMIT_NOFILE — the kernel default (1024) is too low for a single VM now hosting many container lifecycles' worth of inotify FDs from OOM monitoring under sustained churn. ## Tests test/shim/shim_test.go and test/stress/stress_test.go wire in shimtest's new SandboxSuite (lifecycle, platform, ping, single/multiple member containers, per-container independence, error cases) and its stress/benchmark counterparts.

The mechanism is the long-standing CNI "persistent netns" technique: + +1. A dedicated goroutine calls `runtime.LockOSThread()` and never unlocks, + so Go retires the underlying OS thread when the goroutine exits (Go 1.10+). +2. On that locked thread, `unshare(CLONE_NEWNET)` creates a new, empty + network namespace for that thread only + (`pkg/netns/netns_linux.go:116` in containerd). +3. The thread's netns is bind-mounted to a file under `/var/run/netns/` + (or the configured state dir) via `mount("/proc//task//ns/net", + "/var/run/netns/cni-", MS_BIND)`. + Here `` is the containerd process PID and `` is the + TID of the dedicated throwaway thread — `/proc/self/ns/net` cannot be used + because it always returns the thread-group-leader's namespace. +4. The bind-mount anchors the netns to the filesystem.

CNI configures an empty, +process-less netns (which it can do because the bind-mount keeps it alive), +and the sandbox is later started knowing the fully-configured path. + +With the **shim sandboxer there is no pause container** — the shim receives +`netns_path` directly in `CreateSandboxRequest`. (The legacy `podsandbox` +controller creates a pause container which *joins* the pre-existing netns via +an OCI `LinuxNamespace{Type: network, Path: nsPath}`; the shim sandboxer skips +this entirely.) + +For host-network pods (`NamespaceMode_NODE`), no netns is created and +`netns_path` is empty. + +#### What the shim does with netns_path + +**At `CreateSandbox` time** the shim opens the path `O_RDONLY|O_CLOEXEC` and +holds the FD open. This second reference to the netns (alongside the +bind-mount) keeps it alive even if the bind-mount were removed prematurely, +and satisfies the CRI contract. The shim releases this FD after `StopSandbox`. + +``` +CRI layer nerdbox shim + │ │ + │── CreateSandbox(netns_path) ──►│ opens FD to netns_path + │ │ (secondary pin on the bind-mount) + │── StartSandbox ───────────────►│ libkrun FFI thread enters netns + │ │ VM boots + │ │ FD remains open + │ [ pod running ] │ + │ │ + │── StopSandbox ────────────────►│ VM stops + │ │ FD closed + │ [ CNI DEL runs against netns_path ] + │── ShutdownSandbox ────────────►│ final cleanup +``` + +**At `StartSandbox` time** the netns path is passed to the libkrun FFI +executor thread (see [Layer 2](#layer-2--vm-network-stack) below), which +enters the pod netns before any libkrun calls open host resources. + +### Layer 2 — VM network stack + +#### The libkrun FFI executor + +All libkrun FFI calls for a VM context (`krun_create_ctx` through +`krun_start_enter`) run on a **single dedicated OS thread** (the "executor +thread") that holds `runtime.LockOSThread()` for its entire lifetime.

When a container opens a TCP connection, the kernel transparently +rewrites it to `AF_TSI` and proxies it over vsock to libkrun, which performs +the real `connect()` on the host — now inside the pod netns (after the +executor thread's `setns`). + +``` +Container (guest) Host (pod netns) + ┌──────────────────────┐ + connect(AF_INET, 1.2.3.4:80) │ libkrun TSI worker │ + │ │ (executor thread │ + TSI kernel intercept │ lineage, pod netns) │ + │ │ │ + │ ── vsock ──────────────────►│ connect(1.2.3.4:80) │ + │ source: pod IP │ + └──────────────────────┘ +``` + +TSI limitations: IPv4 TCP/UDP only. ICMP, raw sockets, and IPv6 are not +supported. + +##### Fixed: TSIv2/TSIv3 wire-protocol mismatch + +Conformance testing (`NetworkSuite` and `ContainerOutboundTCP` in shimtest) +initially found that TSI did not establish outbound connections at all — a +container's `connect()` never completed, and `strace` on the host process +showed the host-side `connect()`/`socket()` syscall was never even reached. + +Root cause: the kernel patches in `kernel/patches/` implemented an **older +TSI wire protocol (TSIv2)** — `tsi_connect_req { u32 svm_port; u32 addr; +u16 port; }`, a bare IPv4 address — while the bundled libkrun (v1.19.0) +implements **TSIv3**, which uses a length-prefixed, family-tagged address +(`{ u32 svm_port; u32 addr_len; char addr[128]; }`) to support IPv6/AF_UNIX. +libkrun's TSIv3 parser silently misinterpreted the guest's TSIv2 payload +(reading the raw IPv4 address as a bogus `addr_len`), so every connect +request was dropped before any host socket call was made. This was never +caught previously because no test in this repository (or CI) exercised TSI +end-to-end before this pass. + +**Fix:** the kernel patches were replaced with upstream libkrunfw's current +TSIv3 patches (`0011`/`0012`, plus two previously-missing vsock prerequisites, +`0009`/`0010`), matching the wire protocol libkrun v1.19.0 expects. Verified: +all patches apply cleanly (`patch -p1 --fuzz=0`) against a real 6.12.46 +kernel tree; `ContainerOutboundTCP` and `NetworkSuite/{OutboundTCP, +OutboundUDP,DNSResolve}` all pass against the rebuilt kernel. The Dockerfile +patch-apply loop was also hardened with `set -e` (previously a failed hunk +would silently continue, producing an unpatched kernel with no build error). + +##### Known limitation: connected UDP sockets to loopback destinations + +TSI's `tsi_connect()` tries the guest's own local `AF_INET` socket first; +only if that local `connect()` fails does it fall back to proxying via +vsock to the host. For **UDP**, a local `connect()` is a purely local +kernel operation — it succeeds immediately whenever the routing table has +*any* route to the destination, with no live handshake. In the default +no-NIC guest (only `lo` configured), that is true for **loopback** +destinations (`127.0.0.0/8`, always locally routable) but false for real +external IPs (no default route without a NIC, so `connect()` fails with +`ENETUNREACH` and correctly falls through to the vsock/host proxy). + +Net effect: an application using a "dial once, then read/write" UDP pattern +(a *connected* UDP socket, e.g. `net.Dial("udp", ...)` in Go) against a +**loopback** destination gets silently locked to the guest's own isolated +network stack and never reaches the host — even though the exact same +pattern against a real external IP works correctly. Per-datagram +"unconnected" UDP (`sendto`/`recvfrom`, e.g. `net.ListenPacket` + +`WriteTo`/`ReadFrom` in Go) is unaffected: TSI checks for a local listener +on every message and proxies to the host when there isn't one. + +This surfaced in practice as a DNS resolution failure: Go's standard +resolver uses connected UDP internally, and many Linux distributions +(anything using systemd-resolved) point `/etc/resolv.conf` at a loopback +stub resolver (`127.0.0.53`). Copying that file verbatim into the guest (the +`addResolvConf` fallback path) produced a `resolv.conf` whose nameserver is +unreachable from inside the VM. + +This is not a nerdbox- or TSI-specific bug so much as a general +consequence of copying host DNS configuration into an isolated network +environment — Docker and containerd's CRI implementation handle the exact +same systemd-resolved case by preferring systemd-resolved's "full" +resolv.conf (`/run/systemd/resolve/resolv.conf`, which lists the real, +non-loopback upstream nameservers) over the stub file. `addResolvConf` +(`internal/shim/task/ctrnetworking.go`) now does the same: it detects an +all-loopback nameserver list and substitutes the full file when present. +No kernel change was needed or attempted for this — the underlying +connected-UDP-to-loopback behavior in TSI is left as-is (fixing it would +mean patching `tsi_connect()` to add dgram-aware, loopback-aware fallback +logic in `af_tsi.c`, diverging further from upstream; there is no known +open upstream issue for this specific case, likely because most libkrun +consumers do not blindly copy the host's raw `resolv.conf`). + +#### External NIC (explicit virtio-net) + +When the OCI spec annotations carry `io.containerd.nerdbox.network.*`, a +virtio-net NIC is attached to the VM. The NIC is backed by an AF_UNIX socket +(`krun_add_net_unixgram` or `krun_add_net_unixstream`) that connects libkrun +to an **externally-run** L2 network provider. + +This AF_UNIX socket is opened on the executor thread (already in the pod +netns), so the connection to the external provider originates from the pod +netns. + +Supported external providers: +- **passt** (unixgram mode) — passt-style helpers that exchange complete L2 + Ethernet frames as datagrams. +- **gvproxy / vfkit** (unixstream mode) — helpers that frame L2 packets over + a stream connection. + +The shim does **not** spawn the external provider. The user (or a future +shim enhancement) must run it out-of-band and pass its socket path via +annotation.

Mounts created for container rootfs assembly are isolated + from the host and cleaned up automatically when the shim exits. +- Container processes run inside the VM guest kernel. The guest kernel is a + different kernel instance from the host, providing strong isolation. +- The virtiofs share is writable (host-to-guest) but each container's subtree + is isolated: one container cannot see or modify another container's files + within the shared tree. +- The network sandbox FD is opened `O_RDONLY | O_CLOEXEC`. The FD is used + only to pin the bind-mount and (via `SetNetnsPath`) to enter the pod netns + on the executor thread. The shim's control-plane goroutines remain in the + shim's original network namespace. + +## Future work + +The following capabilities are planned but not yet implemented: + +- **Validate netns-scoping end-to-end now that TSI works** — the TSIv2/TSIv3 + protocol mismatch that previously blocked all outbound connectivity is + fixed (see the TSI section above), so `ContainerTrafficScopedToNetworkSandbox` + (shimtest, root-gated) is no longer blocked by TSI itself. It still needs a + clean root run: the sandbox conformance suite's `format_mounts` path (used + automatically when the test process has real root, e.g. under `sudo`) + currently fails with an unrelated ext4-loop-mount permission error in that + configuration, which needs to be fixed in the test harness before the + netns-scoping test can actually execute as root. Once it runs, if it reveals + the executor's in-process `setns` is insufficient (e.g. libkrun uses a + process-global thread pool), pivot to a re-exec approach + (nsenter/cgo-constructor trampoline) so the entire VMM process tree is in + the pod netns. +- **Turnkey virtio networking** — have the shim spawn and manage a passt or + gvproxy process (inside the pod netns) rather than requiring a user-supplied + socket path via annotation. +- **Shared `/dev/shm`** — a per-sandbox tmpfs shared across all containers in + the VM, matching the Kubernetes pod `shm` mount contract. +- **Shared volumes (emptyDir)** — a cross-container shared directory exposed + to multiple member containers. +- **Single ext4 upper layer** — a forthcoming containerd change will support + placing multiple container upper filesystems in one ext4 image, which can be + mounted upfront and eliminate per-container mount overhead on non-root hosts. diff --git a/internal/shim/sandbox/networksandbox.go b/internal/shim/sandbox/networksandbox.go new file mode 100644 index 00000000..1991e19e --- /dev/null +++ b/internal/shim/sandbox/networksandbox.go @@ -0,0 +1,56 @@ +// Copyright The containerd Authors. +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +package sandbox + +// NetworkSandbox represents the host-side network isolation resource +// associated with a sandbox.

From 5cbd0c4006cfdeb26b095b1697e0a1412b21bd81 Mon Sep 17 00:00:00 2001 From: Derek McGowan Date: Sun, 12 Jul 2026 01:42:19 -0700 Subject: [PATCH 03/24] sandbox: give member containers a shared guest network namespace MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the host-side and guest-side halves of per-sandbox network namespace sharing for member containers, addressing two gaps found while auditing how a member container's OCI spec network namespace is handled: 1. No code anywhere sanitized spec.Linux.Namespaces before pushing a container's bundle into the guest. In production CRI, a member container's spec sets the network namespace entry's Path to a host path (containerd's WithPodNamespaces sets it to "/proc//ns/net"), which is meaningless (or actively wrong, if it happens to collide with something) once copied verbatim into the guest — a different kernel with an unrelated PID/namespace space entirely. The same applies to a host Path on any other namespace type. 2. There was no mechanism to ensure all member containers of one sandbox land in the same guest network namespace. Each container got its own namespace (crun's default for an empty-Path entry, or whatever the incoming host path happened to not-quite-mean), so two containers in the same pod had no shared network identity inside the guest. internal/podnetns: shared Path/Name constants ("/run/netns/pod") used by both halves below, kept in a separate no-build-tag package so neither the host transformer nor the guest creator need to import platform-specific code from the other. internal/vminit/podnetns: guest-side creation. At vminitd startup, creates a persistent, named network namespace at the well-known path using the same "persistent netns" technique containerd's CRI plugin uses on the host (see docs/sandbox-architecture.md, Layer 1): a dedicated goroutine locks an OS thread, unshares a new network namespace, and bind-mounts it — the bind-mount is what keeps it alive, so the creating goroutine doesn't need to stay running. No explicit teardown: the namespace is guest kernel state and disappears with the VM. internal/shim/task/podnetns.go: sanitizeNamespaces, a new bundle transformer wired into createSandboxedContainer. Strips host Path values from every namespace type (meaningless in the guest either way), and rewrites/adds the network namespace entry to point at the shared guest path — unless the container has its own dedicated virtio-NIC (io.containerd.nerdbox.ctr.network.* annotation), in which case it keeps its own separate namespace so the existing per-container veth/bridge wiring in internal/vminit/ctrnetworking (which assumes a container owns its namespace) is unaffected. This is distinct from the host-side network namespace *pinning* that SandboxService already performs for the VM as a whole (previous commit): that ensures the VM's outbound traffic uses the CNI-assigned network at all; this is about giving member containers of one pod a shared L2/L3 view of *each other* inside the guest, matching real pod semantics. Neither changes host reachability semantics: TSI is not network-namespace-aware (documented below as "TSI ignores guest-internal network namespaces" — its socket hijack triggers on address family alone, before any netns-aware routing, and its vsock channel to the host isn't real IP routing, so it cannot be scoped or filtered by anything inside the guest; verified empirically, a container placed in its own fresh guest network namespace still reaches a host TCP listener via TSI unchanged). The guest kernel is effectively a single network namespace with respect to host reachability when TSI is enabled; the only real host-isolation boundary is the host-side pod netns pinning, not anything configurable inside the guest. Verified end-to-end via a new shimtest test (MemberContainersShareNetwork): two independently created member containers, one running an in-guest TCP listener and one connecting to it via loopback, successfully exchange data. New unit tests for sanitizeNamespaces in internal/shim/task/podnetns_test.go.

That only works on the legacy path, which boots a fresh VM per container and can add the share before boot (sandbox.WithFS); a sandbox member container is created against an already-running VM, and virtio-fs shares cannot be hot-added after boot, so every such mount failed with "mount ... fstype: virtiofs ... invalid argument". Fix: SharedFS.ShareVolume bind-mounts the host source directly into the sandbox's shared directory tree, which is already exposed to the guest via the single, persistent, pre-boot "containers" virtiofs share (the same one ShareRootfs uses) — no new virtiofs device, no extra guest-side mount step. sandboxVolumeMounter (the sandboxed-path counterpart to bindMounter) rewrites each bind mount's spec Source to the resulting guest path and otherwise leaves Options untouched, so crun's own bind mount from that path into the container enforces whatever read-only/recursion/propagation the spec actually requested. This uncovered a real bug in the first attempt: mounting read-only at the *host* share layer (matching the container's own readonly flag) looked reasonable but is actively wrong — Linux sets MNT_LOCKED on every mount in a recursive read-only bind, and that lock cannot be undone by any later mount (crun's own, or a fresh mount the container creates inside it), so a *non-recursive* read-only container request would become unintentionally, unremovably read-only all the way down. Fixed by always sharing read-write at the host layer and leaving read-only enforcement to crun's own (correctly-scoped) bind mount, which is the only place it should happen exactly once. New shimtest test (vendored): MemberContainerHostVolume, proving the mount is a live share (a host-side update after the container starts becomes visible inside it), not a one-time copy. ## Pod-level DNS/hostname/sysctls (new internal/shim/task/podconfig.go, internal/shim/sandbox/service.go, internal/shim/task/ctrnetworking.go) containerd's CRI layer normally writes resolv.conf/hostname/hosts files into a sandbox root directory and bind-mounts them into every member container (internal/cri/server's linuxContainerMounts + podsandbox.Controller.setupSandboxFiles upstream) — but only the podsandbox controller creates those files; the shim sandboxer path (what this shim implements) gets none of them from containerd, so those bind mounts are silently skipped and DNS/hostname/sysctls from the pod's config never reached containers. SandboxService now stores CreateSandboxRequest.Options verbatim (deliberately uninterpreted — see its doc comment for why the sandbox package stays CRI-agnostic) and exposes it via a new Options() getter. The task package, which already owns other CRI-shaped concerns (DNS annotations), unmarshals it as a k8s.io/cri-api PodSandboxConfig (podSandboxConfig) and feeds DnsConfig/Hostname/Linux.Sysctls into: - addResolvConf: now takes an optional pod DNSConfig, used when there is no per-container DNS annotation override (existing priority order otherwise unchanged). - addHostname (new): sets spec.Hostname and bind-mounts /etc/hostname, mirroring what the podsandbox controller does. - addSysctls (new): merges pod sysctls into spec.Linux.Sysctl, without overriding any per-container value already present. Uses the k8s.io/cri-api v0.36.0 dependency added in the earlier vendor commit (matching the k8s.io/cri-api version containerd v2.3.2 itself pins) — the only way to unmarshal CreateSandboxRequest.Options into the exact same generated protobuf type CRI marshaled it from.

That host path is meaningless in the guest, so the shim must recognize the request and substitute a guest-side equivalent, the same way it already does for the network namespace. Guest side: - internal/podns: well-known guest paths for the shared IPC (/run/ipcns/pod) and PID (/run/pidns/pod) namespaces. - internal/vminit/podns: Manager.EnsureNamespaces creates both namespaces on demand (the first time any container asks for pod namespace sharing), memoized with a sticky error. The IPC namespace is created the same way as the shared network namespace (unshare on a locked OS thread + bind-mount). The PID namespace cannot be: unshare(CLONE_NEWPID) does not move the caller, only the next forked child becomes PID 1, and a PID namespace is torn down the instant its PID 1 exits. So the PID namespace is anchored by a real, persistent process instead (internal/vminit/podpause): vminitd re-execs itself with a hidden "pod-pause" argument and CLONE_NEWPID, and that process reaps reparented orphans and ignores every signal except SIGKILL for the sandbox's lifetime. - plugins/services/podns: TTRPC plugin registration exposing Manager.EnsureNamespaces as the PodNamespaces service (new proto: api/proto/nerdbox/services/podns/v1). Host side: - internal/shim/task/podnetns.go: sanitizeNamespaces now also rewrites IPC/PID namespace entries. Any non-empty incoming Path on either type is treated as "share within this pod" and redirected to the guest's shared namespace; an absent entry (the common case: no pod-level sharing requested) keeps its own namespace and never triggers the guest RPC. This deliberately does not distinguish NamespaceMode_NODE (hostPID/hostIPC) from NamespaceMode_POD: containerd derives the same host path for both, so the shim cannot tell them apart from the data it receives, and both only need cross-container-within-the-pod visibility to satisfy real CRI conformance checks (see test/critest/README.md). - internal/shim/task/podns.go: sharedNamespaces, a lazy, sync.Once-memoized TTRPC client wrapper around the guest's EnsureNamespaces call, so a container whose spec never asks for PID/IPC sharing never pays for it. - internal/shim/task/service.go: fetch the VM client earlier in createSandboxedContainer so sanitizeNamespaces's transformer can use it during bundle.Load. shimtest: MemberContainersSharePID and MemberContainersShareIPC tests (vendored from the shimtest module) verify cross-container PID visibility via /proc and SysV shared memory visibility via new pidscan/shmwrite/shmread testbin commands. critest conformance improved from 81 passed / 8 failed / 24 skipped to 85 passed / 4 failed / 24 skipped. HostPID, HostIpc is false, and PodPID now pass; the remaining IPC-related failure (HostIpc is true) plants a SysV shm segment on the real host machine running critest before creating the sandbox, which no VM-internal namespace can make visible to guest processes -- the same class of limitation as the pre-existing HostNetwork is true gap, now documented in docs/sandbox-architecture.md's new "Pod PID and IPC namespace sharing" section and test/critest/README.md.

The bind mount alone keeps the namespace alive. +- **PID**: a PID namespace has no content of its own and is torn down + (every process in it killed) the instant its PID 1 exits, so it cannot + be anchored by a bind-mount alone the way IPC and network namespaces + can. `unshare(CLONE_NEWPID)` also does not move the calling + thread/process into the new namespace — it only causes the *next + forked child* to become PID 1 of a new namespace. So the guest instead + execs a real, persistent anchor process (vminitd re-execs itself with a + hidden `pod-pause` argument — see `internal/vminit/podpause`) with + `SysProcAttr.Cloneflags: CLONE_NEWPID`, then bind-mounts + `/proc//ns/pid` to `/run/pidns/pod`.

This shim deliberately does not try: any non-empty +incoming `Path` is treated identically, redirected to the pod's shared +guest namespace. In practice this is sufficient for real CRI conformance +(see test/critest/README.md) for everything except a `hostIPC: true` test +that plants a SysV shared memory segment directly on the **real host +machine** before creating the sandbox — no VM-internal namespace can make +guest processes see an object that only exists in a different kernel +entirely. `HostPID`, `HostIpc is false`, and `PodPID` all pass, because +they only depend on cross-container visibility *within the same pod*, +which the shared guest namespace genuinely provides regardless of which +CRI namespace mode nominally asked for it. + ## Sandbox lifecycle ``` diff --git a/internal/podns/podns.go b/internal/podns/podns.go new file mode 100644 index 00000000..23220c69 --- /dev/null +++ b/internal/podns/podns.go @@ -0,0 +1,44 @@ +/* + Copyright The containerd Authors. + + Licensed under the Apache License, Version 2.0 (the "License"); + you may not use this file except in compliance with the License. + You may obtain a copy of the License at + + http://www.apache.org/licenses/LICENSE-2.0 + + Unless required by applicable law or agreed to in writing, software + distributed under the License is distributed on an "AS IS" BASIS, + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + See the License for the specific language governing permissions and + limitations under the License. +*/ + +// Package podns holds the well-known, guest-side identity of the shared +// IPC and PID namespaces that member containers of a sandbox join when +// the pod's CRI NamespaceOptions request POD-level sharing.

See the script's own comment and README.md for why a non-functional image is the right choice here: on the shim-sandboxer path the pause image only needs to resolve in containerd's image store (CRI's ensurePauseImageExists), never mount or run, so making it deliberately incapable of running proves nothing ever depends on it actually working. - cni-net.conflist: minimal bridge+portmap+loopback CNI config, isolated in this harness's own work dir (does not touch /etc/cni/net.d). - README.md: prerequisites, usage, the dummy-pause rationale, and a summary of the conformance run against everything implemented so far in this series (VM-per-pod sandboxing, shared network/PID/IPC namespaces, bind-mount volumes, and pod-level DNS/hostname/sysctls): 85 passed / 4 failed / 24 skipped. The 4 remaining failures are genuine architectural limitations of running each sandbox in its own VM kernel, not bugs, detailed in the README's "Known conformance gaps" section (mount propagation and non-recursive readonly mounts needing a live host kernel mount-graph virtiofs cannot represent, and HostNetwork/HostIpc "is true" checks needing the guest to observe state that only exists on the literal machine running critest, a different kernel entirely from the sandbox's own).

Virtio-fs is a FUSE-based *content* + sharing protocol between the host and guest kernels, not a live kernel + mount-table sync mechanism — there is no channel for a host-side mount + event to propagate into the guest's mount namespace (or vice versa) once + the initial share is established. +- **`should support non-recursive readonly mounts`**: this test mounts a + *separate, real* tmpfs on the host, nested inside a volume's source + directory, *before* the container bind-mounts that directory + non-recursively, and expects the OCI runtime to recognize the nested + mount as a distinct kernel object and leave its own read-write flag + alone. Virtiofs flattens nested host mounts into plain directory content + when sharing a tree — from the guest kernel's point of view there is no + mount boundary there at all, so crun's own (correctly non-recursive) + bind mount has no way to exclude it. Same root cause as the `rshared` + case above: virtiofs cannot represent the host's live kernel mount + graph, only file/directory content. +- **`runtime should support HostNetwork is true`**: this test runs + `netstat -ln` inside the container and expects the *host's own listening + socket* to literally appear in the output — true, introspectable network + stack sharing (the container sees the same socket table as the host), + not just outbound reachability. TSI (this shim's default outbound + networking — see docs/sandbox-architecture.md) proxies individual + outbound connections over vsock; it does not mirror the host's socket + table into the guest, so nothing the shim does with network namespaces + can satisfy this specific check. +- **`runtime should support HostIpc is true`**: this test creates a SysV + shared memory segment directly on the machine running `critest` (the + *real* host), before creating the pod sandbox, then expects a container + with `HostIpc: true` to see it. This shim runs every sandbox inside a + VM, so "the host" from the guest kernel's point of view is the guest's + own root IPC namespace — a different kernel instance entirely from the + machine `critest` is actually creating shm segments on. No IPC namespace + configuration inside the guest can make a segment that only exists in + the real host kernel visible there; it is the same category of + limitation as `HostNetwork is true` above (the guest is not the literal + host), just for SysV IPC instead of the socket table. Pod-level IPC + sharing *between member containers of the same sandbox* — the far more + common Kubernetes use case (pods share IPC by default) — works + correctly and is covered by shimtest's `MemberContainersShareIPC`. + +None of the remaining failures are wired into a `--ginkgo.skip` list yet — see the git log +or ask before assuming any of them are out of scope for follow-up work. diff --git a/test/critest/build-dummy-pause.sh b/test/critest/build-dummy-pause.sh new file mode 100755 index 00000000..da535e18 --- /dev/null +++ b/test/critest/build-dummy-pause.sh @@ -0,0 +1,96 @@ +#!/usr/bin/env bash +# +# Copyright The containerd Authors. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# http://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. +# +# build-dummy-pause.sh builds a deliberately non-functional OCI image and +# writes it as an importable tar (OCI image layout) to $OUT (default: +# ./dummy-pause.tar next to this script). +# +# Why a dummy image at all: CRI's RunPodSandbox unconditionally calls +# ensurePauseImageExists() before starting the sandbox, regardless of which +# sandboxer is configured.

This mirrors the posture of Kata Containers (the most mature production VM-isolated CRI runtime), which excludes tests that assume shared-kernel/host-visibility semantics rather than treating them as bugs to chase -- documented in the new README.md comparison paragraph. Root-caused the sibling 'rslave' propagation spec along the way: it passes and needs no skip entry. This uncovered a more precise root cause for 'rshared' than previously documented: the host->container propagation direction actually works (confirmed by 'rslave', which tests only that direction) -- the test's own setup marks the volume's host source MS_SHARED, and per mount_namespaces(7) a later bind mount taken from an already-shared mount joins the same peer group, which is exactly what SharedFS.ShareVolume's plain bind mount does, so a mount added on the host after container start lands in the same host-kernel peer group as our virtiofs-shared copy and virtiofs simply serves the updated content. Only the container->host direction is truly impossible: a guest-internal mount(2) syscall is never relayed by virtiofs's content-only protocol, so the host kernel can never observe it, regardless of any peer-group configuration. README.md's explanation of both mount-related failures is corrected accordingly. Also fixed a latent, previously-undiscovered usage bug: the script's own header comment recommended "critest -- ARGS", but a literal "--" is consumed by critest's own (ginkgo/go test) flag parser as "stop parsing flags", which silently disables every flag after it -- so the documented usage pattern silently broke --ginkgo.focus/--ginkgo.skip. Usage comments and README.md corrected to pass ARGS directly with no separator.

From ff4dc430010dfef3334eb6e6e454da57e6c6b241 Mon Sep 17 00:00:00 2001 From: Derek McGowan Date: Mon, 13 Jul 2026 00:53:13 -0700 Subject: [PATCH 09/24] vm/libkrun: enter the pod network namespace on the krun_start_enter thread Previously, all libkrun FFI calls (including krun_create_ctx and every krun_add_* configuration call) were serialized onto a dedicated, permanently-locked "executor" OS thread, and loading libkrun plus creating the VM context was deferred until the first such call so that a namespace recorded by SetNetnsPath could be entered on that thread before anything else ran on it. This was overcautious. Auditing the vendored libkrun Rust source shows it spawns no threads at load time or during any krun_set_*/krun_add_* configuration call -- those only mutate a global context map. Every thread relevant to networking (vCPU, virtio-net, vsock/TSI muxer and reaper) is spawned exclusively inside krun_start_enter, as a descendant of whichever thread calls it. So the only requirement is that the goroutine calling krun_start_enter has entered the pod netns first, via runtime.LockOSThread + setns immediately before the call -- there is no need to route every configuration call through that same thread, and no need to defer loading the library or creating the context. Simplify accordingly: - Remove vmExecutor and vmcontext.ensureLoaded entirely. vmcontext methods call libkrun directly again; newvmcontext now creates the krun context immediately (krun_create_ctx), returning an error on failure like every other vmcontext method. - NewInstance goes back to eagerly opening libkrun, initializing logging, creating the VM context, and adding the reserved rootfs disk, all synchronously, rather than deferring any of it. - vmInstance.Start locks its goroutine to its OS thread with runtime.LockOSThread (never unlocked -- Go retires the thread when the goroutine exits) and, if a netns was requested, enters it via setns immediately before calling krun_start_enter. The resulting thread's netns inode is logged for cross-checking during debugging. - Instance.SetNetnsPath is removed from the pkg/vm interface. The pod netns is now supplied via a new vm.WithNetNS StartOpt, consumed by Start itself instead of a separate pre-Start call. - vmInstance now guards against a Start retry silently changing the requested netns: the first Start call (successful or not) records the requested namespace; a later Start call with the same namespace, or none, is a no-op, but a genuinely different, non-empty namespace is rejected outright rather than silently overriding the original request. No behavioral change to which namespace ends up hosting the VM's worker threads: krun_start_enter and everything it spawns still runs strictly after the setns call, on the same locked thread.

That name is meaningless inside the VM guest -- the guest kernel may not have AppArmor enabled at all, and even if it does, it never loaded a profile by that name. Left unmodified, the guest's crun invocation fails outright trying to apply an unknown profile, so any pod requesting an AppArmor profile could never start. Add clearApparmorProfile, a bundle.Transformer that strips the field, and wire it into both the sandboxed and legacy container creation paths, alongside the existing host-namespace-path sanitization this shim already does for the same class of "host-specific setting that is meaningless in a nested guest kernel" problem.

A prior rebase resolved a go.mod conflict between the two by keeping v0.3.0, silently dropping the pseudo-version pointing at that commit -- vendor was never regenerated to match, so every build referencing shimtest.NewSandboxSuite (test/shim/shim_test.go) or StressOptions.Sandbox/SandboxRSSGrowthOverride (test/stress/stress_test.go) failed. Fix: re-resolve the same commit to a pseudo-version based on its actual ancestry (v0.3.1-0.20260712075910-a8efaacdfbb8, now that v0.3.0 is an ancestor) via 'go get', then 'go mod tidy' and 'go mod vendor' to bring in the sandbox suite files that were missing from vendor.

Every non-Linux build failed: - Build (darwin/*), Build (windows/*): cmd/containerd-shim-nerdbox-v1 failed outright ("build constraints exclude all Go files in plugins/shim/sandbox"). - Unit Tests (macos-latest, windows-latest): internal/shim/task failed to compile (undefined: sandbox.SharedFS/SandboxService/ StartOptionsFunc), since it references these unconditionally. Fix: - Remove the Linux-only tag from service.go (nothing in it is platform-specific). - Split sharedfs.go: the struct, constants, and simple accessors stay cross-platform; the real mount-based implementation of ShareRootfs/ShareVolume/Unshare/UnshareAll moves to a new sharedfs_linux.go, with a sharedfs_other.go stub returning a not-supported error on other platforms (mirroring the existing networksandbox_linux.go/_other.go split). - Remove the Linux-only tag from the two plugin registration files; their own dependencies (internal/shim/sandbox/vm, pkg/vm) were already cross-platform. Separately, Project Checks (file headers) failed on the same set of files plus a few others (internal/vm/libkrun/krun_linux.go/krun_other.go, internal/shim/task/sandboxopts.go, pkg/vminit/initd/ containers_mount_linux.go, test/critest/*.sh): they used a "//" line-comment license header (and, where present, put a build tag *after* the header) instead of the project's established "/* */" block-comment form with any build tag placed *before* it. Reformatted all of them to match every other file in the tree exactly (verified byte-for-byte against the canonical header), and normalized the two shell scripts' comment spacing (blank lines between paragraphs, per convention) to match.

Add the nsfs-magic check (mirroring the identical, already-existing validation in internal/vm/libkrun's vmcontextSetNetns) via Fstatfs on the opened FD. A path that isn't backed by nsfs is still accepted rather than rejected: shimtest's non-root test suite deliberately pins a plain regular file in place of a real netns to avoid requiring CAP_SYS_ADMIN or kernel bind-mount support, and that technique must keep working. A debug log line now flags this case for visibility. Also fixes the file's license header to the project's standard block-comment form (flagged by the Project Checks CI job -- see the previous commit for the full explanation).

Go's filepath.Join cleans ".." segments as part of the join, so a destination containing them (e.g. "/../../etc/passwd") resolves outside sourceRootfs entirely -- filepath.Join("/root", "../../etc/passwd") returns "/etc/passwd" -- letting a placeholder file be created anywhere on the host the shim process can write to. Fix: resolve the path with containerd/continuity/fs.RootPath instead, which both cleans ".." components relative to the root (rather than letting them escape it) and safely resolves any symlinks already present inside sourceRootfs component-by-component, so a symlink planted inside the shared rootfs tree can't be used to escape it either.

Both of the type assertions unwrapping a plugin.Type's registered value (SandboxPlugin -> *sandboxManager, TaskPlugin -> taskAPI.TTRPCTaskService) are ok-checked, returning a descriptive error instead of panicking the shim if the wiring is ever wrong -- consistent with the same fix applied to the sandbox plugin's own unwrapping in the previous cross-platform-build commit.

This causes every capability to be cleared on exec: per Linux's exec-time capability recomputation, a process whose effective UID is non-zero *within its own current user namespace* has its capability sets cleared to empty when it execs, even though the namespace's creator normally holds a full capability set in it. Since the shim always execs itself into the new namespace (clone+exec, not unshare -- see the doc comment on why), the re-exec'd child ends up with no capabilities at all inside its own namespace: unable to perform the bind mounts SharedFS needs for sandboxed containers (mount(2) returning EPERM), and unable to even call getsockopt(2) on socket fds inherited across the namespace boundary (reproduced standalone by the existing script/userns-check). This is invisible to every build, lint, and unit test job, and to any CI job that happens to run privileged (hence "Unit Tests" and "Build" passing) -- it only surfaces as every sandboxed-path shimtest/CRI test failing at the actual mount syscall, exactly matching the "Integration Tests" CI failures on this PR (TestShim/SingleContainer and every other sandbox-suite case: "share rootfs ... err: operation not permitted"). Fix: map container UID/GID 0 to the real host UID/GID instead. This grants no additional real host privilege: every interaction with a resource outside the namespace is still translated back through the mapping to the real, unprivileged host UID for permission checks. It does keep the child's effective UID zero *inside its own namespace* across exec, which is what preserves the capability set and lets the actual mount()/getsockopt() calls the shim needs succeed. Updated script/userns-check to use the same mapping, so it continues to answer "does userns work at all here" for this code path. Verified: the full shimtest suite, which failed every sandboxed test with this exact "operation not permitted" error when run as a plain non-root user, now passes cleanly (0 failures) under the same non-root invocation that CI uses; full integration suite (12/12) and golangci-lint (linux/darwin x amd64/arm64, only the 5 known pre-existing gosec findings) also verified clean.

That misses the common case entirely: a real CRI overlay snapshotter, `ctr run` with overlayfs, and this repo's own erofs layer format all present the rootfs as a multi-entry overlay/erofs assembly (ext4 scratch + erofs layers + a final "format/mkdir/overlay" mount), never a single "bind" entry, so the loop matched nothing and created zero placeholders. In practice this was masked rather than caught by any current test: the OCI runtime (crun, inside vminitd) auto-creates a missing bind-mount destination file as long as the underlying rootfs stays writable, and every current snapshotter/production rootfs is writable (only a fully-extracted, explicitly read-only bind rootfs -- the non-root shimtest path -- genuinely needs a pre-created placeholder, and that's the one shape the old loop happened to handle). The existing doc comment's premise ("the rootfs will be bind-mounted read-only") was also simply wrong for the writable overlay/erofs case. Fix: udsPlaceholderSource (socketforward.go) inspects only the *last* entry in r.Rootfs -- the one mountutil.All actually mounts at the final assembled path, since every earlier entry (lower layers, ext4 scratch devices) exists purely to feed that last mount. If it's a plain read-only bind, its Source is used before ShareRootfs runs (the only genuinely read-only-after-assembly case, matching prior behavior). Otherwise -- including the common multi-entry overlay/erofs shape, where no single entry's Source is the final tree at all -- the placeholder is written into the assembled rootfs itself (SharedFS.RootfsHostPath), which stays writable and is only available once ShareRootfs has run. Added a regression test (TestCreateRootfsPlaceholders_OverlayShapedRootfs) that exercises exactly the previously-missed shape, plus table-driven coverage of udsPlaceholderSource's mount-shape decision (TestUDSPlaceholderSource). Verified: go build/vet/gofmt clean; golangci-lint across linux/darwin x amd64/arm64 (only the 5 known pre-existing gosec findings); full unit suite; 12/12 integration tests; task test:shim both non-root and as root (root exercises the erofs/overlay rootfs shape this fixes) -- only the pre-existing, unrelated ResourceReleaseOnShutdown flake, identical before and after this change; cross-platform build (linux/darwin/windows x amd64/arm64); verify-vendor clean.
