Allow operators to configure a default Kubernetes runtimeClassName that
is applied to sandbox pods when the CreateSandbox request does not
specify one. This avoids requiring every API caller to explicitly set the
runtime class for clusters that always need a specific RuntimeClass
(e.g. kata-containers, nvidia).
The fallback is applied in the Kubernetes driver only — per-request
values still take priority, and an empty default (the built-in) preserves
existing behavior (field omitted, cluster default applies).
* fix(helm): create sandbox JWT secret under cert-manager
The cert-manager install path (certManager.enabled=true,
pkiInitJob.enabled=false) left the gateway StatefulSet unable to start
because nothing created the openshell-jwt-keys Secret: cert-manager owns
TLS Secrets but does not mint the sandbox JWT signing key, and the
certgen hook only rendered when pkiInitJob.enabled was true.
Separate JWT signing-key provisioning from TLS PKI provisioning:
- certgen: add a --jwt-only mode that creates only the Opaque JWT
signing Secret, for use when another controller owns TLS Secrets.
- certgen.yaml: render the hook when pkiInitJob.enabled OR
certManager.enabled is true. cert-manager takes precedence and runs
the hook with --jwt-only even if pkiInitJob.enabled remains true.
Remove the mutual-exclusion failure between the two values.
- _helpers.tpl: add openshell.sandboxJwtSecretName, shared by the hook
and the StatefulSet mount.
- Update values, README, docs, architecture, and the
debug-openshell-cluster skill to reflect the new precedence; the
documented cert-manager install no longer needs pkiInitJob.enabled=false.
Closes#1691
* fix(helm): honor cert-manager precedence for client CA volume
The client CA volume logic treated pkiInitJob.enabled as proof that
built-in PKI owns the client CA. With cert-manager precedence now
allowing certManager.enabled=true alongside the default
pkiInitJob.enabled=true, that assumption mounts the server TLS cert
secret as the client CA and ignores
certManager.clientCaFromServerTlsSecret=false, which can break mTLS or
trust the wrong CA.
Gate the pkiInitJob.enabled term with (not certManager.enabled) in all
three client CA conditions (volume mount, volume definition, and secret
selection) so cert-manager owns TLS when enabled. Add a Helm test suite
covering built-in PKI, cert-manager shared CA, the regression config
(cert-manager + clientCaFromServerTlsSecret=false + default pkiInitJob),
and the no-client-CA case.
The existing docs omitted or misstated several requirements when running
the gateway as a container with the Docker compute driver:
- OPENSHELL_GRPC_ENDPOINT is required; the Docker driver uses only the
scheme (http/https) — host and port are substituted automatically with
host.openshell.internal and the gateway's own bind port
- Supervisor binary must be extracted to a host path before starting the
gateway; bind-mount sources are resolved by the host Docker daemon so
the path must be identical inside and outside the gateway container
- Docker socket access requires adding the docker group (UID 1000 default)
- Port binding should remain 127.0.0.1; Docker driver adds a bridge
listener automatically
- add --server-san host.openshell.internal to generate-certs for mTLS
- Complete the mTLS docker run with all Docker driver requirements
- Add deploy/docker/gateway.toml — TOML config for the Docker driver
- Add deploy/docker/docker-compose.yml referencing the TOML
- Add docs/get-started/tutorials/docker-compose.mdx tutorial page
- Remote gateway registration instructions (--remote flag)
Address reviewer feedback:
- Move Docker Compose tutorials card to the bottom of the list
- Replace inline YAML snippet in Docker Compose section with a reference

- Clarify OPENSHELL_DB_URL is safe in compose.yml (plain SQLite path,

* fix: address vertex review findings
* test(sandbox): retry on spurious Ok in fork-exec ambiguity test
On arm64 under heavy CI load, the /proc fd scan in
find_socket_inode_owners can transiently miss the parent process's
socket fd entry, returning only the child as an owner. This causes
resolve_process_identity to return Ok (single owner, no ambiguity
check fires) instead of the expected ambiguous-ownership Err.
Extend the retry loop to also handle unexpected Ok results, mirroring
the existing retry for transient Err results. 10 retries at 50ms gives
a 500ms settling window, which is sufficient for procfs to stabilize
on loaded arm64 runners.
* fix: address vertex review regressions
* docs(router): clarify stream_response semantics for Vertex rawPredict routing
Document the three call sites of prepare_backend_request and their
stream_response values in a caller table:

- send_backend_request_streaming: true → :streamRawPredict
- verify_backend_endpoint: explicitly false to probe the unary endpoint
Cross-reference the table from build_provider_url and
is_vertex_anthropic_rawpredict_route so the stream_response=true guard
in the suffix upgrade branch is understood in full context.
Also note that is_vertex_anthropic_rawpredict_route is a structural
predicate (model_in_path + anthropic_messages + :rawPredict suffix),
not a named-provider check, so any future provider with the same route
shape inherits the transforms automatically.

Sandbox processes running on Deno couldn't TLS-verify connections to
services signed by OpenShell's per-sandbox ephemeral CA because Deno
doesn't consult `SSL_CERT_FILE` / `NODE_EXTRA_CA_CERTS`. Deno reads its
own `DENO_CERT` env var (additive PEM bundle, same shape as
`NODE_EXTRA_CA_CERTS`) for that.
Add `DENO_CERT` to `child_env::tls_env_vars` pointing at the standalone
OpenShell CA cert (not the combined system+sandbox bundle, since DENO_CERT
is additive). The three callers in `process.rs` / `ssh.rs` iterate the
array, so the size bump from 5 to 6 entries flows through without
caller changes.
Updates the security best-practices doc to enumerate `DENO_CERT`
alongside the other trust-store env vars.

Migrate all sandbox and VM driver network policy enforcement from
iptables to nftables. nftables provides atomic ruleset loading, a
cleaner rule syntax, and is the standard netfilter interface in modern
kernels.
Sandbox bypass enforcement (openshell-sandbox):
- Replace iptables chain of individual rule insertions with a single
atomic nftables ruleset load via nft -f
- New nft_ruleset module with pure functions for ruleset generation
and unit tests
- Combine log and reject rules in one inet family table (handles both
IPv4 and IPv6 in a single ruleset)
- Fall back to reject-only ruleset when kernel lacks nft_log support
- Enable net.netfilter.nf_log_all_netns so log rules work from
non-init network namespaces
- Use temp file for nft ruleset loading instead of stdin for
compatibility with minimal VM guest environments
VM TAP networking (openshell-driver-vm):
- Replace iptables NAT/forwarding rules with nftables equivalents
- New nft_ruleset module for TAP network rule generation with unit
tests
- Atomic table-per-TAP-device lifecycle (create/destroy)
- Host-side rules provide NAT infrastructure and defense-in-depth
isolation (input chain restricts VM to gateway port only, forward
chain blocks unsolicited inbound); primary security enforcement
happens inside the VM guest via the sandbox supervisor's own rules
VM init script:
- Load nft kernel modules at sandbox init
- Enable nf_log_all_netns sysctl for bypass detection logging
OCSF / docs:
- Update firewall rule engine references from iptables to nftables
- Document host firewall interaction model and two-layer enforcement

* feat(gateway): add TOML configuration file (RFC 0003)
Introduces an opt-in --config / OPENSHELL_GATEWAY_CONFIG flag that loads a
TOML file with gateway-wide settings and per-driver tables. Source
precedence is CLI > env > file > built-in default, implemented via clap's
ValueSource so existing flags and env vars keep their priority.
Driver crates (kubernetes, docker, podman, vm) now derive Deserialize on
their config structs. SupervisorSideloadMethod gains Deserialize with
kebab-case rename. A per-driver inheritance allowlist on the loader side
overlays [openshell.gateway] shared defaults (default_image,
supervisor_image, image_pull_policy, guest_tls_*, ssh_handshake_skew_secs,
client_tls_secret_name, host_gateway_ip, enable_user_namespaces) onto
each [openshell.drivers.<name>] table before deserialization.
The Helm chart renders a new gateway-config ConfigMap and mounts it at
/etc/openshell/gateway.toml. The migrated OPENSHELL_* env entries are
dropped from the StatefulSet — only the Secret-backed
OPENSHELL_SSH_HANDSHAKE_SECRET remains. database_url stays on --db-url.
Adds examples/gateway/gateway.example.toml and updates architecture/gateway.md
with the source precedence and inheritance rules.
* docs(gateway): drop ssh_handshake_skew_secs and ssh_handshake_secret from examples
Both fields are scheduled for removal. Remove the example values and the
env-only note so the gateway.toml example and the architecture doc stop
recommending settings that will not exist much longer.
* docs(rfc): correct OPENSHELL_CONFIG to OPENSHELL_GATEWAY_CONFIG in RFC 0003
* docs(gateway): add per-driver TOML example configurations
Adds focused single-driver examples next to the comprehensive
gateway.example.toml: kubernetes, docker, podman, and microvm. Each one
demonstrates the realistic settings for that driver plus how shared
[openshell.gateway] defaults inherit into the driver table.
A new unit test (`checked_in_examples_parse`) loads every example through
the config_file loader so schema drift fails CI rather than silently
shipping a broken example.
* refactor(gateway): drop image_pull_policy from shared inheritance
Kubernetes and Podman use mutually-incompatible vocabularies for the same
TOML key:
- Kubernetes: `Always | IfNotPresent | Never` (free-form string passed
verbatim to the K8s API).
- Podman: `always | missing | never | newer` (strict lowercase enum
deserialised into `ImagePullPolicy`).
No value means the same thing in both drivers. Sharing the key at
`[openshell.gateway]` scope and inheriting it into every active driver's
table meant any value safe for one driver was either wrong or silently
dropped for the other (`IfNotPresent` → `ImagePullPolicy::Missing` after
`.unwrap_or_default()`). Operators run one driver per gateway, so the
"shared default" never pays for itself.
Make `image_pull_policy` driver-local:
- Remove the field from `GatewayFileSection` and from
`inheritable_keys()` for both Kubernetes and Podman.
- Drop the file→`RunArgs` merge for the gateway-scope key.
- Stop unconditionally clobbering the driver value with
`config.sandbox_image_pull_policy` in the runtime wiring — only apply
the CLI/env override when it was set (and, for Podman, only when it
parses into the lowercase enum).
- Move the key under `[openshell.drivers.kubernetes]` and
`[openshell.drivers.podman]` in every example, the RFC, the
architecture doc, and the Helm-rendered gateway ConfigMap.
The supervisor pull policy follows the same shape: it is K8s-only and
moves into `[openshell.drivers.kubernetes]` alongside `image_pull_policy`
in the Helm template.
* fix(gateway): address review feedback on TOML configuration
Resolves the P1 and P2 issues raised in PR #1317:
- Helm gateway ConfigMap moves `grpc_endpoint` under
`[openshell.drivers.kubernetes]` so the default install no longer fails
the gateway's `deny_unknown_fields` schema check.
- `kubernetes_config_from_file` and `podman_config_from_file` only let
the gateway-wide CLI/env `grpc_endpoint` overwrite the driver-table
value when it was actually supplied, preserving file-only configs.
- Kubernetes driver default `image_pull_policy` is now empty (was Podman
vocabulary "missing"), so default deployments let the Kubernetes API
apply its own policy instead of being rejected.
- New `disable_tls` gateway field plumbs `.Values.server.disableTls`
through the TOML ConfigMap instead of relying on env vars dropped from
the StatefulSet.
- StatefulSet pod template now carries a `checksum/gateway-config`
annotation so `helm upgrade` rolls pods when the ConfigMap changes.
- Auxiliary listener resolution preserves the full `SocketAddr` from
`health_bind_address` / `metrics_bind_address`, so a loopback-pinned
health port is not silently relocated onto the public bind address.
- `ssh_session_ttl_secs` from the file is now applied to `Config` (it
was previously accepted by the loader but never read).
New regression coverage: cli-level merge tests for the new fields plus
helm-unittest assertions for the ConfigMap shape, checksum annotation,
and `disable_tls` rendering.
* docs(gateway): consolidate gateway TOML examples into docs reference
Replaces the per-driver example files under examples/gateway/ with a
single published reference page at docs/reference/gateway-config.mdx
covering source precedence, layout, the full example, and the four
per-driver examples (Kubernetes, Docker, Podman, microVM). Drew flagged
during PR #1317 review that the examples belong with the user-facing
docs rather than in a sibling examples/ directory.
The cross-references in architecture/gateway.md and RFC 0003 are updated
to point at the new docs page; the round-trip test in config_file.rs is
removed (schema coverage stays on the inline parses_full_example test
and per-field merge tests — doc-snippet drift belongs in a separate
docs-lint, not in a cross-tree Rust unit test).
* refactor(core): move DEFAULT_K8S_NAMESPACE into K8s driver
The constant is Kubernetes-specific (used only by KubernetesComputeConfig's
Default impl) and does not belong in openshell-core. Relocate it to the
driver crate that owns the K8s vocabulary; openshell-core retains only
truly cross-cutting defaults.
* refactor(core): move Podman bridge default into Podman driver
DEFAULT_NETWORK_NAME is Podman vocabulary, consumed only by the Podman
driver. Also drops the unused DEFAULT_IMAGE_PULL_POLICY constant.
* docs(auth): scrub remaining SSH handshake secret references
Sweeps the trailing mentions left after the rebase: the gateway
config-file module doc, the Helm gateway-config ConfigMap header,
the gateway-config.mdx env-only note, and the RPM systemd unit
comment for init-gateway-env.sh.
* docs(gateway): clarify OPENSHELL_GRPC_ENDPOINT applies to all drivers
The previous comment implied the callback endpoint was Kubernetes-only,
but the value is propagated to every compute driver (Kubernetes, Docker,
Podman, VM) and must be reachable from wherever the sandbox runs.
* refactor(gateway): move driver options into config (#1394)
Signed-off-by: Drew Newberry <anewberry@nvidia.com>
* fix(e2e): regenerate gateway config via TOML for docker + podman harnesses
The gateway CLI flags moved into TOML config tables in 560550d2 (#1394),
which made every existing e2e/with-{docker,podman}-gateway.sh invocation
fail with "unexpected argument '--sandbox-namespace'" (and a long tail
of similar driver-specific options) before the gateway could even bind.
Replace the obsolete CLI flags with a synthesized
`[openshell.drivers.<driver>]` table written to `${STATE_DIR}/gateway.toml`
and passed via the new `--config` flag. Only the gateway-wide flags
that survived 560550d2 (bind-address, port, drivers, db-url, tls-*,
disable-tls, log-level, health-port) stay on the command line.
Both scripts get a small `toml_string` helper to properly TOML-quote
the values (the previous `%q` printf format produced bash-escape, not
TOML-escape). The Docker harness also corrects two field names that
diverged from the driver schema: `docker_network_name` →
`network_name`, and the supervisor binary/image plumbing now reads
through to `supervisor_bin` / `supervisor_image` in the same table.
The Podman harness drops `--ssh-gateway-port` (deleted in 560550d2 —
gRPC + SSH are multiplexed on the same port now) and substitutes
`network_name` + `gateway_port` for the obsolete `--sandbox-namespace`
(which the Podman driver never had as a typed field).
* fix(core): swap bind-only 0.0.0.0 SSH gateway host for cluster URL host
CLI's resolve_ssh_gateway treated 0.0.0.0 as a loopback "keep as-is"
when the cluster URL was also loopback, so the SSH proxy connected to
0.0.0.0:port. The unspecified address is never a valid connect target
and is not present in any TLS cert SAN, which produced BadCertificate
TLS handshake failures during `openshell sandbox create -- ...` in
docker/podman e2e (e.g. bypass_detection).
Resolution: when the server returns 0.0.0.0 or :: as the gateway host
and both endpoints are loopback, fall back to the cluster URL's host
(which the CLI is already using to reach the gateway, so it must
resolve and match the cert).
* fix(e2e): repair podman harness on macOS
Podman 5.x with the applehv/libkrun provider no longer creates the legacy
~/.local/share/containers/podman/machine/podman.sock symlink, and
`podman system service` is a Linux-only subcommand — the macOS client
delegates the API service to the VM. Both assumptions in the harness
were stale, so the script tried to start a temporary service that podman
rejected with "unknown flag: --time".
- Discover the macOS socket via `podman machine inspect` instead of the
hardcoded path.
- On Darwin, fail fast with a "start podman machine" message rather than
attempting the Linux-only `podman system service` fallback.
- Write socket_path into [openshell.drivers.podman] so the in-process
driver picks up the discovered socket; the driver reads TOML only
after the config refactor (560550d2), so OPENSHELL_PODMAN_SOCKET alone
was no longer enough.
* fix(server): use clone_from for TLS client CA assignment
clippy 1.95.0 rejects assigning the result of `Clone::clone()` to an
existing variable under `-D warnings` (`assigning_clones`). Switch to
`clone_from(&...)` to satisfy the lint and avoid the redundant
allocation.

* refactor!(auth): drop SSH handshake secret in favor of mTLS
The OPENSHELL_SSH_HANDSHAKE_SECRET / x-sandbox-secret mechanism was
misnamed: it does not authenticate SSH (which flows over the
RelayStream gRPC RPC and is gated by mTLS plus supervisor Unix-socket
permissions). It only gated a small set of sandbox-to-gateway
control-plane RPCs, and production deployments already enforce mTLS
on that channel — so the shared secret was redundant.
Replace the secret check with an mTLS-presence marker. Sandbox-class
methods (ReportPolicyStatus, PushSandboxLogs,
GetSandboxProviderEnvironment, SubmitPolicyAnalysis, GetSandboxConfig,
GetInferenceBundle) accept callers without a Bearer token; the gRPC
mTLS handshake is the trust boundary. Dual-auth methods treat
Bearer-present as full-scope CLI access and Bearer-absent as
sandbox-restricted scope via validate_sandbox_caller_update.
Drops the secret from all drivers (K8s, Podman, VM), the sandbox gRPC
interceptor, the Helm chart (values + pre-install hook + StatefulSet
env), the RPM bootstrap script, the man pages, and the
debug-openshell-cluster skill. Also removes the never-read
ssh_handshake_skew_secs flag and config field.
BREAKING CHANGE: --ssh-handshake-secret / OPENSHELL_SSH_HANDSHAKE_SECRET
and --ssh-handshake-skew-secs / OPENSHELL_SSH_HANDSHAKE_SKEW_SECS are
removed from the gateway, sandbox, and all driver binaries. The
openshell-ssh-handshake K8s Secret is no longer managed by the chart;
operators may delete the orphan. Deployments using
--disable-gateway-auth must enforce caller authentication at the
fronting proxy, since the gateway no longer validates a per-request
secret on sandbox-class methods.
Refs OS-174.
* docs(auth): scrub residual SSH handshake secret references
Sweep across docs, e2e scripts, the Podman driver README/NETWORKING
notes, the RPM/Helm/setup guides, the gateway man page, and RFC 0003
to remove instructions and examples that still referenced
OPENSHELL_SSH_HANDSHAKE_SECRET / --ssh-handshake-secret /
ssh_handshake_skew_secs. The mechanism is gone; nothing should still
suggest setting it. Negative-assertion regression tests are kept so
the env var cannot silently be re-introduced.
* test(drivers): drop SSH handshake secret negative-assertion tests
The supporting code, env vars, CLI flags, and config plumbing are
gone — these tests asserted absence of strings that no longer have
any path to being set. Remove the guards from the Docker, Podman,
Kubernetes, and VM driver test modules.
* fix(cli): cp-style sandbox download and workspace-boundary check
`openshell sandbox download` produced a directory at the host destination
instead of writing the source bytes as a regular file, and did not refuse
sandbox-side paths that resolved outside `/sandbox` (only `creds.json` was
rejected, by filesystem policy rather than by an explicit check).
Mirrors the cp-style design from the upload-side fixes (#667 / #694 and
#885 / #952): destination resolution now respects trailing slashes and
existing-directory destinations, single-file sources land as regular files
via a staged extraction and atomic rename, and the function delegates the
SSH tar stream to a shared helper. Adds an explicit lexical
workspace-boundary check on the sandbox-side source — required on the
download side because filesystem policy alone is not a substitute for an
explicit check when crossing the trust boundary in the leak direction.
Signed-off-by: Tinson Lai <tinsonl@nvidia.com>
* fix(cli): canonicalise sandbox download path remotely and quote tar member
The lexical check in `validate_sandbox_source_path` clears any path whose
components stay under `/sandbox` after `.` and `..` are folded out, but it
cannot see symlinks. A workspace-relative symlink such as
`/sandbox/etc-link -> /etc` lets `openshell sandbox download <name>
/sandbox/etc-link/passwd /tmp/passwd` slip through, then `tar -C
/sandbox/etc-link passwd` follows the link on the sandbox side and
streams `/etc/passwd` back to the host.
Add `canonicalize_sandbox_source_path` which runs `realpath -e --` over
SSH and rejects the result unless it still equals `/sandbox` or starts
with `/sandbox/`. The lexical guard stays as a cheap fail-fast for
obviously-bad inputs, and the rest of the download flow now uses the
canonical path everywhere a tar invocation or probe might dereference a
symlink.
While editing the single-file branch, also add the `--` separator before
the basename in `tar cf - -C <parent> -- <name>`. Without it, a sandbox
file whose basename starts with `-` (e.g. `--checkpoint-action=...`) is
parsed by GNU tar as an option rather than a member, which at best
fails the wrap and at worst triggers tar option behaviour. The directory
branch passes literal `.` and is unaffected.
Cover both fixes with pure-function tests: `is_under_sandbox_workspace`
gets accept/reject pairs (the same predicate the post-realpath
validator uses) and the new `build_single_file_tar_cmd` helper asserts
the `--` separator and shell escaping survive any future refactor.

`tempfile` was promoted from `[dev-dependencies]` to `[dependencies]`
once the cp-style single-file download path started using

line stayed behind by accident — entries under `[dependencies]` are
already available to test compilation, so the second declaration is
dead weight.

* test(cli): add E2E coverage for sandbox download paths
Adds four end-to-end tests for `openshell sandbox download` so the

`SandboxGuard::exec` harness helper and pulls it back, exercising
`sandbox_sync_down_file` without an upload phase.
* `sandbox_download_directory_only` — seeds a small directory tree and
pulls it recursively, exercising `sandbox_sync_down_directory`.
* `sandbox_download_rejects_symlinks_pointing_outside_workspace` —
regression for the high-severity finding. Plants three escape shapes
(`/sandbox/etc-link -> /etc`, `/sandbox/passwd-link -> /etc/passwd`,
and a path with a symlinked component `/sandbox/etc-link/passwd`) and
asserts all three are refused with a workspace-boundary error before
any tar streams. Also checks the host destination stays empty so a
silent leak would surface.
* `sandbox_download_handles_dash_leading_basename` — regression for the
medium-severity finding. Seeds a file named `--checkpoint-action=evil`
and verifies it downloads with byte-for-byte contents, proving the
`--` separator stops tar parsing the basename as an option.
The harness gains a single new method, `SandboxGuard::exec`, that wraps
`openshell sandbox exec --name <name> --no-tty -- <argv>`. Existing
tests preferred the upload path to populate sandbox state, but the
regression cases need to plant filesystem state the upload flow cannot
produce (symlinks, files whose basenames clap would otherwise reject).

* docs(cli): note cp-style destination and workspace boundary on download
`openshell sandbox download` now refuses any source path that resolves
outside `/sandbox` (lexically or through a symlink), and the
single-file branch follows `cp`-style placement rules. Document both
so users hitting the workspace-boundary error or the
"land at exact path vs land inside dir" decision can self-serve.

* test(cli): tolerate miette line-wrapping in symlink-rejection assertions
`sandbox_download_rejects_symlinks_pointing_outside_workspace` matched
the substring `"outside the sandbox workspace"` against the CLI's error
output. The check is correct in spirit but fragile in practice: miette
wraps long single-line errors across multiple lines at terminal width
and inserts a `│ ` continuation marker, so the substring breaks across
the wrap and the test fails even though the canonicalisation step
correctly refused the source.
Split the match into three short markers — `resolves to`, `outside the`,
`sandbox workspace` — each guaranteed to fit on one wrapped line. The
combined check is stricter than the original (it now requires evidence
that the remote `realpath -e` step actually ran, not just the boundary
refusal) without inheriting the wrap fragility.

Add supervisor.sideloadMethod to the Kubernetes setup chart values table
and the compute drivers reference table. The value was added in the
ImageVolumeSource sideload PR and controls whether the supervisor binary
is delivered via an OCI image volume mount or an init container, with
auto-detection based on cluster version when left empty.
Update the server.sandboxNamespace description in both pages to reflect
that the Helm chart now derives it from the release namespace by default
when the value is left empty.
Add opt-in support for Kubernetes user namespace isolation on sandbox
pods. When enabled, container UID 0 maps to an unprivileged host UID
and capabilities become namespaced, providing defense-in-depth for the
supervisor process.
Configuration is two-layered: a cluster-wide default via
OPENSHELL_ENABLE_USER_NAMESPACES (default false) and a per-sandbox
override via the new `user_namespaces` field on SandboxTemplate.
When user namespaces are active, the pod security context is extended
with SETUID, SETGID, and DAC_READ_SEARCH capabilities to match the
bounding-set requirements inside a user namespace.
Introduces SandboxPodParams struct to replace long argument lists on
sandbox_to_k8s_spec and sandbox_template_to_k8s.
Validated end-to-end on OCP 4.22 (K8s 1.35.3, CRI-O 1.35, RHEL
CoreOS, kernel 5.14) with full SSH tunnel and non-identity UID mapping.
