* refactor(sandbox): keep runtime transports behind the backend

Signed-off-by: Drew Newberry <anewberry@nvidia.com>

* fix(docker): mount the runtime control volume read-only

The sandbox runtime only dials the supervisor-owned control socket, so
it does not need write access to the control volume. Mount it read-only
in the runtime container and stop staging the control directory through
the runtime bundle; the supervisor stager already initializes it through
its own writable mount.

* fix(kubernetes): separate legacy and runtime-initiated control services

Keep os-boundary selecting the workload and add os-supervisor for runtime-initiated connections. Bind the mode marker to its runtime generation so a restart by an older gateway does not inherit stale mode metadata. Preserve the legacy Service across creation and restart, validate the active endpoint, and drop the Service patch permission.

Matthew Grossman 1fff8b97b9 feat(podman): honor OCI image working directories (#3982)
* fix(supervisor): report rejected OCI working directories as WorkspaceValidationFailed

The RFC 0012 split dropped the supervisor exit status that drivers map to
the WorkspaceValidationFailed condition. An image WORKDIR the sandbox
identity cannot use then surfaced as ControlSupervisorStartFailed on
Docker and as a signal kill on Podman.

The supervisor now exits with the reserved status when the sandbox rejects
the image working directory. Docker maps that supervisor exit during
readiness and monitoring, and Podman maps the supervisor companion's exit
instead of the workload's.

Signed-off-by: Matthew Grossman <mgrossman@nvidia.com>

* feat(podman): honor OCI image working directories

Podman sandboxes now use a custom OCI image WORKDIR as the workspace and
as the working directory for agent commands, matching Docker. Empty, /,
and /sandbox values keep the managed /sandbox workspace volume.

A custom workspace stays in the image's container filesystem: no
workspace volume, no archive upload, and no root setup step. Resolve the
image ID, user, environment, and working directory from one pinned
inspection, validate the workdir with the shared OCI rules, and reject
Podman control-path overlaps and image volumes or driver mounts that
cover it. The runtime starts from / and passes the resolved path to agent
commands with --workdir.

Add podman_oci_identity to the Podman CI test list.

Signed-off-by: Matthew Grossman <mgrossman@nvidia.com>

* fix(drivers): preserve custom workspace failures across supervisor cleanup

Check the Podman custom workspace rather than the absent managed volume in the OCI identity E2E. Classify Bollard wait errors by exit code and record Docker workspace failures before removing the supervisor so readiness retains the specific failure reason.

Signed-off-by: Matthew Grossman <mgrossman@nvidia.com>

* fix(docker): use sandbox ID for recorded startup failures

Keep the workload container ID for Docker inspection and use the sandbox ID to retrieve the monitor failure. Test with distinct identifiers so the lookup cannot accidentally pass with a container ID.

Signed-off-by: Matthew Grossman <mgrossman@nvidia.com>

* refactor(podman): keep WORKDIR change focused on workspace behavior

Remove the new cross-driver workspace failure classification path and its monitor/readiness workaround. Preserve Podman WORKDIR resolution, mount safety, and workspace rejection without requiring a distinct condition reason.

Matthew GrossmanandEvan Lezar 13c248fd45 fix(podman): create managed workspace volumes owned by the workload identity (#3981)
* fix(podman): create managed workspace volumes owned by the workload identity

Podman now creates the managed /sandbox volume with uid/gid options for the
resolved workload identity, so the workload starts directly as that
identity. This fixes rootful sandboxes whose image USER or policy
run_as_user could not write to a root-owned /sandbox, and removes the
root-then-drop workspace chown start path.

Resource admission accepts the managed workspace volume when its options
match the workload container's final identity, or are empty for volumes
created by older gateways. The channel volume still requires empty options.

Russell Bryant aa848f164d fix(core): fall back to podman CLI when no API socket is found (#1858)
* fix(core): fall back to podman CLI when no API socket responds

Auto-detection only checked well-known Podman socket paths, so a Podman
machine exposing its API socket at a non-standard location went
undetected. The symlink at a well-known path is not always present; it
varies by Podman version, machine provider, and platform.

Extend detect_podman_socket() to fall back to podman CLI discovery when
no well-known candidate responds: podman info --format json determines
whether the service is local or remote, and podman machine inspect
resolves the host-side forwarded socket for VM-backed machines. All
existing callers (driver auto-detection, the Podman driver, and the VM
driver's container-engine fallback) pick this up without change.

Select the machine backing the active Podman connection instead of the
first entry from podman machine inspect, honoring podman's connection
precedence: CONTAINER_CONNECTION, then CONTAINER_HOST (mapped to a
connection by URI), then the containers.conf default. An explicit
endpoint that maps to no known machine is left unresolved rather than
guessing an unrelated machine. When CONTAINER_HOST is an explicit unix://
socket, use that path directly since podman info connects through it.

Update the gateway config reference and the Podman driver README, which
described probe-only detection.

Signed-off-by: Russell Bryant <rbryant@redhat.com>

* fix(core): inspect podman machine by name and bound discovery probes

Address two startup defects in Podman socket auto-detection:

- Remote discovery ran `podman machine inspect` with no arguments, which
  inspects only `podman-machine-default`. On a host whose default
  connection is a different machine, selection fell back to the first
  (wrong) entry, so the gateway could operate against the wrong backend.
  Resolve the active machine first and inspect it by name, trying the
  `-root`-stripped machine for rootful connections and returning None
  when no machine can be mapped instead of substituting another.

- `podman info`, `podman machine inspect`, and `podman system connection
  list` used unbounded `Command::output()`, so a stalled machine, SSH
  connection, or helper could hang gateway startup indefinitely. Route
  all three through a bounded runner that kills and reaps the child on a
  documented deadline and returns None so detection can continue.

* fix(core): bound podman probe stdout drainage and kill descendants

The previous timeout only bounded waiting for the direct child to exit.
Draining stdout still called read_to_end, which waits for pipe EOF — a
Podman probe can leave a daemonized descendant (SSH multiplexer, gvproxy)
that inherited the stdout pipe, so drainage could wait indefinitely even
after the direct child exited, defeating the deadline.

Run each probe as its own process-group leader, cap stdout drainage by
the same deadline via a channel, and on expiry kill the whole process
group so descendants holding the pipe are terminated and EOF is reached.
Add a regression test where the direct child exits but a backgrounded
descendant keeps stdout open.

Signed-off-by: Russell Bryant <rbryant@redhat.com>

* fix(core): make podman probe deadline absolute against escaped descendants

The prior drainage timeout still ended in an untimed rx.recv() after
killing the process group. A descendant that escaped the probe's process
group (e.g. via setsid) while holding the stdout pipe would not be killed,
so read_to_end never saw EOF, the reader never sent, and that recv() could
block gateway startup indefinitely.

On drainage timeout, best-effort kill the process group and return None
immediately, abandoning the reader thread instead of waiting on it again.
The deadline now bounds the whole call regardless of what descendants do.
Add a regression test whose stdout-holding descendant escapes the process
group (`set -m`) and assert the call still returns promptly.

Philippe Martin 0a1f246587 feat(sandbox,podman): trust corporate CA for https:// proxies and intercepted TLS (#2512)
* feat(sandbox,podman): trust corporate CA for https:// proxies and intercepted TLS

The corporate proxy chaining only accepted plain http:// proxy URLs, so
operators whose forward proxy terminates TLS with a private corporate CA
had no way to reach it, and TLS-intercepting proxies (mitmproxy, squid
ssl-bump) that re-sign tunneled server certificates broke every upstream
handshake after CONNECT.

The supervisor now accepts https:// proxy URLs: it wraps the connection to
the proxy in TLS before the CONNECT handshake, verifying the proxy
certificate against the built-in Mozilla roots, the system CA bundle, and an
optional operator corporate CA bundle. The upstream dial returns a
Plain/Tls stream enum consumed generically by the relay paths.

The corporate CA is delivered as a driver-supplied command-line argument
(--upstream-proxy-ca-bundle), never an environment variable, matching the
hardened proxy-config model where a sandbox image cannot influence the
operator's egress boundary. It is folded into the sandbox combined trust
bundle (write_ca_files) and the L7 upstream verification store
(build_upstream_client_config) at startup, so intercepted upstream
handshakes succeed and sandbox workloads trust the re-signed certificates.
Configuration is fail-closed: a CA bundle set without a proxy, or an
unreadable or certificate-free file, is fatal rather than silently
weakening the trust boundary.

The shared parse_upstream_proxy_url validator accepts https:// (recording
the scheme so the driver and supervisor agree), keeping the explicit-port
requirement. The Podman driver gains a proxy_ca_bundle operator setting
(TOML, --sandbox-proxy-ca-bundle, OPENSHELL_SANDBOX_PROXY_CA_BUNDLE) that
bind-mounts the host PEM read-only into the sandbox (a CA certificate is not
secret) and points --upstream-proxy-ca-bundle at it, with a create-time
readability check.

The standalone dev gateway task passes OPENSHELL_SANDBOX_PROXY_CA_BUNDLE
through to the generated podman config, so a local gateway can be pointed at
a TLS-intercepting proxy without hand-editing the regenerated TOML.

* fix(sandbox): reject CA bundles with valid PEM framing but invalid X.509 DER

The proxy CA bundle validation counted PEM blocks that base64-decoded
successfully, but did not verify the decoded bytes were accepted as
trust anchors by RootCertStore. A bundle with syntactically valid PEM
framing but invalid DER would pass the startup check while contributing
zero usable anchors, causing opaque TLS failures at runtime instead of
a fail-closed startup error.

Validate decoded certificates through RootCertStore::add_parsable_certificates
and reject the bundle unless at least one is accepted.

* fix(sandbox,podman): allow proxy auth without insecure acknowledgement for https:// proxies

For an https:// proxy the Proxy-Authorization credential travels inside
the verified TLS session, so the proxy_auth_allow_insecure
acknowledgement is unnecessary. Previously both http:// and https://
proxies required it, producing a misleading cleartext-risk diagnostic
for a path that is already encrypted.

Skip the requirement when the proxy URL uses https://; the
acknowledgement is still tolerated if set. Updated in both the
supervisor and Podman driver validation paths, with docs and tests.

* fix(e2e): sign the https proxy fixture listener cert with a CA

The corporate-proxy E2E fixture served a single `openssl req -x509`
certificate as its TLS listener identity. OpenSSL marks that certificate
`basicConstraints: critical, CA:TRUE`, and rustls refuses a CA
certificate presented as an end-entity certificate (CaUsedAsEndEntity).
The supervisor's TLS handshake with the proxy therefore failed, the
upstream dial errored, and the workload's CONNECT was dropped without a
response, so podman_corporate_proxy_trusts_ca_bundle_for_https_proxy
failed on the approved destination while policy denial still worked.

Generate a corporate CA and a separate listener leaf signed by it, serve
the leaf chain, and publish only the CA as the bundle the supervisor
trusts. This is what an intercepting proxy actually presents, and it
exercises the corporate-CA trust path rather than pinning the listener
certificate itself.

krishicks 2c0adf4868 feat(podman): export driver traces over OTLP (#2782)
Mirror the VM driver tracing setup for Podman. Export standalone driver
spans through OTLP/gRPC as the distinct openshell-driver-podman service,
propagate W3C context across ComputeDriver RPCs, record bounded RPC names
and failures, and flush buffered spans during graceful shutdown.

Podman still runs in-process when selected as a built-in gateway driver.
Add a temporary tracing shim that partitions gateway and Podman spans by
target into separate tracer providers while preserving their shared trace
and parentage. The shim also emits the same ComputeDriver server boundary
that the tonic layer emits out of process, keeping the observable trace
shape stable when Podman is eventually extracted.

operations, and cleanup. Document the service boundary and cover it with
isolated and repeated tracing tests.

* refactor(driver): extract shared supervisor binary helpers

Move supervisor binary extraction, caching, and validation helpers from
the Docker driver into openshell-core::driver_utils so both Docker and
Podman drivers can reuse them.

Moved helpers: extract_first_tar_entry, write_cache_binary_atomic,
supervisor_cache_path, temp_extract_container_name, and
validate_linux_elf_binary.

The shared extract_first_tar_entry gains entry-type and empty-payload
checks that the Docker-local version lacked.  supervisor_cache_path
takes a driver_subdir parameter so each driver caches under its own
namespace (docker-supervisor vs podman-supervisor).

Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* feat(driver-podman): add userns config

Add a `userns` option to the Podman compute driver that maps to
Podman's user namespace modes.  The mode string is split on the first
colon into the API's `nsmode` and `value` fields so parameterized
values like `auto:size=65536` and `keep-id:uid=1000,gid=1000` are
forwarded correctly.  When the mode is `auto`, the container spec
also sets `idmappings.AutoUserNs = true` as required by the API.

An allowlist validates the mode at startup: `auto` and `keep-id`
accept optional parameters; `host`, `private`, and `nomap` reject
them; everything else is an error.

Podman image volumes use overlay mounts internally and the kernel
does not support idmapped mounts on overlay (`mount_setattr` returns
EINVAL).  When userns is configured (any mode except `host`), the
driver extracts the supervisor binary from the image to a host-side

Philippe Martin 77e5c32217 feat(sandbox,gateway): route sandbox egress through corporate HTTP proxy (#2245)
* feat(sandbox,gateway): route sandbox egress through corporate HTTP proxy

- Chain sandbox egress through a corporate HTTP proxy so outbound
  traffic from within the sandbox respects the host proxy settings
- Forward sandbox proxy environment variables to the generated Podman
  config so the proxy is applied consistently to Podman-managed workloads

Signed-off-by: Philippe Martin <phmartin@redhat.com>

* fix(sandbox,podman): make corporate proxy routing operator-owned

The operator-configured corporate egress proxy was injected under the
conventional HTTPS_PROXY/HTTP_PROXY/NO_PROXY names as defaults beneath
sandbox spec/template environment, so a sandbox creator could redirect
egress at an arbitrary proxy or disable proxying with NO_PROXY=*.

Route the boundary through reserved, supervisor-only variables
(OPENSHELL_UPSTREAM_HTTPS_PROXY/HTTP_PROXY/NO_PROXY) written in the
Podman driver's required-variable tier. Any sandbox-supplied value under
a reserved name is stripped before the operator value is applied, so the
supervisor never observes a reserved proxy variable the operator did not
set. The supervisor now reads only the reserved names and ignores the
conventional proxy variables the sandbox controls.

Add the reserved proxy variables to the supervisor-only child-environment
denylist so the corporate proxy URL and any embedded credentials are not
inherited by the sandbox workload, which reaches egress through the local
policy proxy and never needs them.

Signed-off-by: Philippe Martin <phmartin@redhat.com>

* feat(sandbox,podman): deliver corporate proxy credentials via secret file

Proxy credentials were embedded inline in the proxy URL, so they were
stored in gateway.toml and exposed in container metadata via
'podman inspect'.

Reject inline 'user:pass@' credentials in https_proxy/http_proxy at
startup (parsed with the url crate rather than hand-splitting), and add a
proxy_auth_file option pointing at a 'user:pass' file. The driver stages
that file as a per-sandbox root-only Podman secret, mounts it at a fixed
path, and exports only the path in the reserved
OPENSHELL_UPSTREAM_PROXY_AUTH_FILE variable, so the credential never
appears in config, environment, or container metadata. Reading the file
fails closed on a missing, empty, or control-character-bearing value.

The supervisor reads the credential from the mounted file and builds the
Proxy-Authorization: Basic header, rejecting control characters, and no
longer derives credentials from URL userinfo. The auth-file path is added
to the child-environment strip list, and the generated gateway.toml is
written owner-only (mode 0600).

Signed-off-by: Philippe Martin <phmartin@redhat.com>

* fix(sandbox,podman): fail closed on invalid upstream proxy configuration

The reserved OPENSHELL_UPSTREAM_* variables are an operator-owned egress
boundary, but the supervisor treated present-but-invalid values as unset:
an unsupported or malformed proxy URL was ignored with a warning, an
unreadable auth file proceeded without credentials, and a malformed
credential silently became unauthenticated. Any of these could quietly
downgrade the corporate proxy boundary to direct dialing or
unauthenticated proxy access.

Make every configured-but-invalid proxy or auth setting fatal to
supervisor proxy startup, emit an OCSF ConfigStateChange failure event
before refusing, and share URL validation semantics between the Podman
driver and the supervisor through a single validator in
openshell-core (parse_upstream_proxy_url), so a value accepted at
sandbox-create time can never be rejected in-container or vice versa.

Inline user:pass@ URL credentials are now fatal in the supervisor too
(previously warn-and-strip), matching the driver. Unset or empty
variables still mean no proxy; only present-but-invalid values fail.
Error paths never include credential content.

Addresses the fail-closed review item on #2245.

Signed-off-by: Philippe Martin <phmartin@redhat.com>

* fix(sandbox,podman): finish the fail-closed upstream proxy credential contract

The upstream proxy URL already had a single shared validator, but the
credential did not: the Podman driver rejected only CR/LF/NUL while the
supervisor rejected every control character, so a credential accepted at
sandbox-create time (e.g. one containing a tab) could still be rejected
in-container. Present-but-whitespace reserved OPENSHELL_UPSTREAM_*
values were also silently treated as unset, quietly downgrading the
operator's egress boundary to direct dialing.

Add parse_upstream_proxy_credential to openshell-core as the single
source of truth for the documented user:pass credential form (non-empty
user, no control characters, trimmed) and use it in both the Podman
driver's secret staging and the supervisor's Proxy-Authorization header
construction. Error variants carry no payload so credential content can
never leak into messages.

Make a present-but-empty reserved variable fatal to supervisor proxy
startup instead of meaning "unset"; only fully unset variables disable
the proxy. The driver correspondingly rejects an empty no_proxy at
config time so it can never inject a value the supervisor refuses.

#2245.

* fix(sandbox,podman): close remaining fail-open upstream proxy config paths

Two configuration paths could still silently run without the proxy
boundary the operator believed was in effect.

A no_proxy bypass list configured without any https_proxy/http_proxy
was accepted by both the driver and the supervisor and simply meant
"dial everything directly". Reject it on both sides, exactly like the
existing proxy_auth_file-without-proxy rule: an operator who wrote a
bypass list assumed proxying was active, so accepting it hides a
fail-open state.

The gateway.sh dev script guarded proxy settings with [[ -n "${VAR:-}"
]], which conflates unset with explicitly-empty and dropped the latter
before the gateway's validation could see it. Use ${VAR+x} instead so
a set-but-empty variable is written into gateway.toml and rejected at
startup by validate_proxy_config rather than silently discarded.

Addresses the remaining fail-open configuration review item on #2245.

* fix(sandbox,podman): reject upstream proxy URLs with path, query, or fragment

parse_upstream_proxy_url accepted URLs like http://proxy.corp.com:8080/some/path
and silently discarded everything after host:port, a lenience inherited
from the original supervisor parser. A forward proxy is addressed by
host:port only, so extra components indicate a misconfiguration (for
example a pasted endpoint URL) and silently truncating them violates
the present-but-invalid-is-fatal contract enforced everywhere else in
this configuration surface.

Reject a path, query, or fragment in the shared validator with a new
UnexpectedComponent error. A bare trailing slash remains accepted
because the url crate normalizes an absent http path to "/", making the
two indistinguishable. Both the Podman driver (gateway startup) and the
supervisor (sandbox startup) inherit the rule through the shared
parser, keeping their semantics identical by construction.

Addresses the proxy URL component review item on #2245.

* fix(sandbox,podman): remove plain-HTTP upstream proxy support

The http_proxy path tunneled plain-HTTP requests through the corporate
proxy with CONNECT to port 80 and then sent origin-form requests down
the tunnel. Conventional enterprise forward proxies expect plain HTTP
as absolute-form requests sent directly over the proxy connection, and
commonly refuse CONNECT to port 80, so the setting looked supported but
failed against typical deployments. Tunneling also blinds the proxy to
the one protocol it could inspect.

Narrow the feature to TLS (CONNECT) egress only, which is the
conventional and already-correct case: plain-HTTP requests now always
dial the destination directly, and only client CONNECT tunnels chain
through the corporate proxy. Remove the http_proxy config field, the
--sandbox-http-proxy / OPENSHELL_SANDBOX_HTTP_PROXY driver surface, the
reserved OPENSHELL_UPSTREAM_HTTP_PROXY variable, and the UpstreamScheme
plumbing. The feature never shipped, so this is a clean removal; a
stray http_proxy key in gateway.toml still fails loudly through the
config's deny_unknown_fields.

Removing the plain-HTTP proxy branch also removes its host-gateway
special case; the architecture doc now documents the real host-gateway
behavior (add driver-injected host aliases to the reserved NO_PROXY
list) instead of an invariant the HTTPS path never implemented.

Plain-HTTP forwarding through a corporate proxy can return later as
absolute-form forwarding behind its own design review.

* fix(sandbox,podman): escape generated TOML and require explicit proxy URL form

Escape backslashes, quotes, and control characters when gateway.sh writes
proxy values into gateway.toml, so a hostile or unusual environment value
cannot corrupt the config or inject extra keys.

Restrict the upstream proxy URL grammar to the documented http://host:port
form: a scheme-less value is no longer normalized to http:// and a missing
port is no longer silently defaulted to 80. Docs, README, and CLI help now
state the explicit-form requirement consistently.

Also fix a test-only call of handle_tcp_connection that was missing the
upstream_proxy argument added in an earlier commit.

Signed-off-by: Philippe Martin <phmartin@redhat.com>

* fix(sandbox,podman): preserve tunneled bytes read with the CONNECT response

The CONNECT handshake reads the corporate proxy's response in chunks, so
the read that completes the header block can also contain the first
tunneled payload bytes. Those bytes were discarded, silently corrupting
the start of the tunnel for server-speaks-first destinations or proxies
that coalesce writes.

connect_via now returns a PrefixedStream that replays any bytes received
past the response terminator before reading from the socket again; writes
pass through unchanged. Direct dials wrap the stream with an empty prefix
so downstream relay and TLS paths keep a single stream type, and
tls_connect_upstream is generalized to any AsyncRead + AsyncWrite stream.

Adds regression coverage for a combined response/payload read and for
prefix replay ordering.

* fix(sandbox,podman): gate cleartext proxy Basic auth behind an explicit opt-in

Proxy-Authorization: Basic is base64 over the plain-TCP connection to the
http:// corporate proxy, so anyone on the network path between the sandbox
host and the proxy can recover the credential. Sending it is now an
explicit operator decision instead of an implicit side effect of
configuring proxy_auth_file.

Add a proxy_auth_allow_insecure driver setting (CLI
--sandbox-proxy-auth-allow-insecure, env
OPENSHELL_SANDBOX_PROXY_AUTH_ALLOW_INSECURE), delivered to the supervisor
as the reserved OPENSHELL_UPSTREAM_PROXY_AUTH_ALLOW_INSECURE variable.
Fail-closed pairing on both sides: an auth file without the
acknowledgement is rejected at gateway startup and at supervisor startup,
as is the acknowledgement without an auth file or any value other than
'true'. gateway.sh writes the key only as a TOML boolean; a non-boolean
value is emitted as a quoted string so the gateway rejects it at startup
instead of risking injection.

Documents the exposure prominently in the gateway config reference, the
driver README, and the sandbox architecture doc.

* fix(sandbox,podman): honor port qualifiers and resolved addresses in NO_PROXY

Two divergences from the documented NO_PROXY contract:

- A port-qualified entry (internal.corp:8443) was silently stripped to its
  hostname and bypassed the proxy for every port, excluding traffic the
  operator never listed. Entries now keep the optional :port qualifier
  (also on IP and CIDR entries) and only apply to that destination port; a
  trailing qualifier that is not a valid port stays part of the pattern
  instead of widening the entry.

- IP and CIDR entries only matched IP-literal hosts, so a bypass like
  10.0.0.0/8 never applied to hostnames resolving into that range. NO_PROXY
  evaluation now sees the validated resolved addresses: an IP/CIDR entry
  matching through resolution authorizes a direct dial of only the
  addresses it contains, so a bypass scoped to an internal range cannot
  widen into a direct dial of addresses outside it. Hostname-level matches
  (loopback, wildcard, domain entries, IP-literal hosts) keep authorizing
  all validated addresses.

proxy_for is replaced by decision(host, port, resolved) returning either
the proxy endpoint or the permitted direct-dial subset, and dial_upstream
restricts the direct connect to that subset.

Adds regression coverage for port-scoped bypasses on domain, IP, and CIDR
entries, invalid port qualifiers, resolved-address matching, and
split-resolution subset dialing.

* fix(sandbox,podman): bind proxied CONNECT tunnels to validated addresses

The CONNECT request sent to the corporate proxy carried the destination
hostname, so the proxy resolved the name itself and the addresses that had
passed SSRF and allowed_ips validation were discarded. Split-horizon DNS
or rebinding at the proxy could then reach internal or otherwise
unapproved destinations through a tunnel the supervisor logged as
validated, and IP-range policy could not be enforced at all on proxied
dials.

CONNECT now targets a validated resolved address by default: the proxy
performs no DNS resolution and the tunnel stays bound to the answer the
supervisor checked. The hostname still travels inside the tunnel (TLS SNI,
application Host), so destination servers behave normally. In
split-horizon networks, operators point the gateway host at the corporate
resolver so internal names validate to their internal addresses.

For proxies whose ACLs filter on hostnames and reject IP CONNECT targets,
a new proxy_connect_by_hostname opt-in (CLI
--sandbox-proxy-connect-by-hostname, env
OPENSHELL_SANDBOX_PROXY_CONNECT_BY_HOSTNAME, reserved
OPENSHELL_UPSTREAM_PROXY_CONNECT_BY_HOSTNAME) restores hostname CONNECT,
documented as re-opening proxy-side resolution and making the proxy's ACLs
the effective egress control. Fail-closed pairing on both sides: the
opt-in without a proxy, or any value other than 'true', is fatal.

Adds regression coverage for the IP CONNECT request line (including IPv6
bracketing and hostname non-leakage), the hostname opt-in, and the
config pairing rules in driver and supervisor.

* fix(sandbox,podman): reject empty port after bracketed IPv6 proxy host

http://[fd00::1]: passed the explicit-port check because the bracketed
branch only tested for a colon after the bracket, then fell back to port
80 — violating the fail-closed http://host:port contract and potentially
sending configured Basic credentials to an unintended service. Require a
non-empty suffix after ]:, matching the unbracketed branch, and cover the
case in the shared parser tests.

* fix(sandbox,podman): fall back across validated addresses in proxied CONNECT

The direct path hands TcpStream::connect the whole validated address list
and it falls back across them, but the validated-IP CONNECT path attempted
only the first address, so a dual-stack destination could fail through the
corporate proxy even when a later validated address was reachable.

connect_via_validated tries each validated address in order under one
aggregate CONNECT_HANDSHAKE_TIMEOUT budget, returning the first success;
when every attempt fails the error names the attempt count and carries the
last failure. An empty address list is rejected up front.

Adds regressions for first-fails/second-succeeds fallback (asserting both
CONNECT request lines), the aggregate all-addresses failure message, and
the empty-list rejection.

  both in the supervisor-only variable test.

  mise run gateway help text, marked Podman-only and stating the
  auth-file/acknowledgement pairing, and complete the gateway-key list in
  the Podman README.

* fix(sandbox,podman): cap each proxied CONNECT attempt within the shared budget

A proxy that accepted the first CONNECT request but never responded
consumed the entire aggregate handshake timeout, so later validated
addresses were never tried and the hang defeated the multi-address
fallback.

Each attempt is now time-boxed to its fair share of the time remaining
before the shared deadline (remaining / attempts_left): a hanging attempt
is cut off with enough budget left for every remaining address, while
time a fast failure does not use rolls over to later attempts and the
total never exceeds CONNECT_HANDSHAKE_TIMEOUT. A timed-out attempt is
recorded like any other failure, and the aggregate error distinguishes
all-attempted from budget-exhausted runs.

Adds a first-hangs/second-succeeds regression driven through a
test-visible budget parameter so it runs in about a second instead of a
real 30s window.

* fix(sandbox,podman): deliver corporate proxy config on the supervisor argv

The proxy settings were injected as reserved OPENSHELL_UPSTREAM_* container
environment variables. The driver only wrote names the operator configured,
but container runtimes layer the spec environment over ENV values baked
into the sandbox image, so an image could supply NO_PROXY=*, enable
hostname CONNECT, or point an unconfigured deployment at an
attacker-controlled proxy whenever the operator left a field unset.

The settings now travel as supervisor command-line arguments
(--upstream-proxy, --upstream-no-proxy, --upstream-proxy-auth-file,
--upstream-proxy-auth-allow-insecure,
--upstream-proxy-connect-by-hostname) built by the driver from operator
config. The driver sets the container entrypoint and command explicitly,
so neither sandbox spec/template environment nor image ENV can influence
argv, and an omitted flag genuinely means unconfigured — in every
supervisor topology, since the supervisor no longer consults its
environment for these settings at all. Credentials stay on the root-only
secret mount; only the mount path appears on argv.

The reserved environment names, their strip-list entries, and the
env-based validation surface are removed. UpstreamProxyConfig::from_args
replaces from_env, reusing the same shared fail-closed validation and
pairing rules keyed by the CLI flag names.

Driver tests now assert the argv contract, including that sandbox-supplied
environment cannot add, remove, or redirect proxy flags; supervisor tests
cover from_args mapping and its pairing rules.

* fix(sandbox): parse bracketed IPv6 authorities in client CONNECT targets

parse_target split the CONNECT authority at the first colon, so an
IPv6-literal target like [2001:db8::1]:443 always failed port parsing and
IPv6-literal clients could never reach policy evaluation; a regression
test even locked in that failure. Parse the RFC 3986 bracketed form and
return the host bracket-free, matching what DNS resolution, SSRF
validation, NO_PROXY matching, and the upstream CONNECT builder expect.
Unclosed brackets, a missing or empty port after the bracket, and
non-numeric ports are rejected; unbracketed behavior is unchanged.

Replaces the failure-locking test with success coverage for bracketed
targets and adds malformed-bracket rejection cases.

The per-sandbox proxy-auth credential secret is staged before the

that drive create_sandbox to a container-create failure and to a
start failure, and delete_sandbox for an out-of-band deletion, asserting
each path issues the DELETE for the per-sandbox proxy-auth secret so a

Existing tests exercised validated-IP CONNECT and the upstream-TLS helper

that stands up a fake corporate proxy tunneling to a fake TLS server and
drives the real path: connect_via_validated CONNECTs to the validated
address, the proxy splices the tunnel, and tls_connect_upstream verifies
the upstream certificate against the original hostname carried in SNI.

It asserts the CONNECT authority is the validated IP and never the
hostname, that verification succeeds for the matching hostname, and that a
mismatched hostname is rejected — proving a rebinding or split-horizon
substitution behind the proxy cannot pass certificate verification.

* fix(sandbox,podman): bound proxy-auth reads, reject port 0, fix stale comment

Three review findings:

- CWE-400: the proxy-auth credential file was read with an unbounded
  read_to_string on both the driver (sandbox-create) and supervisor
  (startup) paths, so a huge file or a special file such as /dev/zero
  could exhaust memory. Add a shared bounded reader in openshell-core that
  rejects non-regular files, caps the size at 4 KiB, and reads at most that
  many bytes; the driver runs it via spawn_blocking. Covers oversized,
  special-file, and missing-path cases on both sides.

- Reject an upstream proxy URL with port 0: it passed the explicit-port
  check and startup validation but is not a connectable TCP port, so every
  proxied dial would fail later. Add a typed ZeroPort error with
  shared-validator and Podman-config tests.

- Reword a driver-config comment that still described a 'reserved
  variable' to match the argv transport.

* fix(sandbox): open proxy-auth file non-blocking to reject FIFOs promptly

read_upstream_proxy_credential_file opened the path with a blocking
File::open before the regular-file check, so a configured FIFO with no
writer would block open() indefinitely — hanging sandbox creation on the
driver and supervisor startup. Open with O_NONBLOCK on Unix so the open
returns immediately, then reject the non-regular file as before;
O_NONBLOCK has no effect on the later read of a regular file. Adds a
mkfifo regression asserting the reader returns promptly with a
non-regular-file error instead of hanging.

* test(podman): cover corporate proxy egress across driver and supervisor

The existing corporate-proxy tests construct config structs or call CONNECT
helpers directly, so none of them detect a break in the wiring between
layers: gateway TOML deserialization, the Podman argv and secret-mount
semantics, supervisor CLI parsing, or policy denial before proxy contact.

Add a Podman e2e that drives the whole chain against a fake authenticated
forward proxy and asserts that an approved TLS request traverses it with a
validated-IP CONNECT, a policy-denied destination is refused with 403
without ever reaching the proxy, credentials arrive through the mounted
per-sandbox secret, and deleting the sandbox removes that secret.

SupportContainer is a new harness fixture. Unlike ContainerHttpServer it
probes readiness with a TCP connect rather than an HTTP GET, so it can host
a forward proxy and TLS servers, and it exposes container logs and network
IP for assertions.

* test(podman): restart the gateway on the proxy-config panic path

The panic cleanup for the temporary corporate proxy configuration
restored the gateway TOML but left the gateway process running with the
temporary configuration still loaded, which could poison later test
binaries in the same run. Nothing restarted it: the only ManagedGateway
is the short-lived one inside restart_gateway, and its Drop only calls
start, which does not reload config for an already-running gateway.

Restore and synchronously stop/start the gateway in Drop, and set
restored only after the normal restore and restart both succeed so a
failed restart no longer suppresses the fallback.

* fix(supervisor-network): derive the loopback proxy bypass from resolved IPs

The automatic bypass treated the host string "localhost" as proof that
the destination was loopback and returned every resolved address. A
sandbox controls its own /etc/hosts and resolve_socket_addrs consults it
before DNS, so a workload could map localhost to any policy-allowed
address and dial it directly, escaping the operator proxy and the
inspection and audit boundary it exists to provide.

Check the resolved addresses instead: the name bypasses only when the
resolution is non-empty and every address is loopback. A mixed answer is
not partially honored, and an IP literal is still authoritative for
itself. A spoofed localhost falls through to the entries below, so an
explicit operator NO_PROXY entry is still honored.

This matches the trust model detect_trusted_host_gateway already applies
to the same hosts file, which validates the mapped address rather than
the alias.

Mesut Oezdil 744a65d52e fix(driver-podman): avoid panic when HOME is unset on macOS (#2327)
* fix(driver-podman): resolve Podman socket via auto-detection

Align Podman socket selection with the existing Docker model: explicit
config wins, otherwise probe openshell-core for a responsive socket.
This also fixes the original HOME-unset panic, since resolution no
longer hardcodes a per-OS default path.

- add detect_podman_socket() in openshell-core, mirroring
  detect_docker_socket
- PodmanComputeConfig.socket_path is now Option<PathBuf>, no default
- remove default_socket_path() (podman driver) and podman_socket_path()
  (vm driver), both replaced by the shared detector
- update server env override and CLI for the new Option type
- add tests: responsive-candidate detection in openshell-core, and
  config-error (not panic) when no socket is configured or reachable

* fix(driver-podman): address review feedback on socket resolution

Extract socket resolution into resolve_socket_path, taking the
detector as a parameter so tests do not depend on real env vars or
the host's actual Podman state. Replace the flaky env-mutating test
with three deterministic cases: explicit wins, detected is used when
absent, and neither source errors.

Fix the socket_path doc comment to describe it from a config user's
point of view, matching DockerComputeConfig's docstring. Drop a
comment that only made sense next to the Docker driver code.

Update the Podman README and gateway docs: they described a fixed
per-OS default path that no longer exists, replace with the actual
probe-then-fail behavior.

* docs(driver-podman): simplify socket default description

Previous wording was self-contradictory (says auto-detect on unset,
then lists the same var as a probed candidate) and omitted the Linux
/run/user/uid/podman/podman.sock candidate.

Russell Bryant c5d1d76d94 refactor(sandbox): replace iptables with nftables for network policy enforcement (#1401)
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
  architecture in VM driver README and compute drivers reference

Taylor MutchandDrew Newberry b61a98dbad feat(gateway): add TOML configuration file (RFC 0003) (#1317)
* 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.

Taylor Mutch 7a0c444445 refactor!(auth): drop SSH handshake secret (#1274)
* 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.

* wip

* refactor(docker): use native rust builds for split gateway/supervisor images

Drop the in-Docker BUILD_FROM_SOURCE path so both images consume only
prebuilt binaries staged natively via tasks/scripts/stage-prebuilt-binaries.sh.
This mirrors what CI does and reuses the host's cargo target cache and
sccache across rebuilds.

- Dockerfile.gateway: nvcr.io/nvidia/distroless/cc:v4.0.4 base (the 4.0.0
  tag does not exist on nvcr.io; the registry uses a v prefix). GNU-linked
  binary copied to /usr/local/bin.
- Dockerfile.supervisor: scratch base, static musl binary. Static linkage
  lets the image stay scratch while still being executable as a Kubernetes
  init container.
- skaffold.yaml: each artifact invokes tasks/scripts/docker-build-image.sh,
  which stages the binary natively (cargo / cargo-zigbuild) and then builds
  the image. Drops the cross-build.sh dependency from the supervisor build.
- seccomp.rs: add a local SYS_kexec_file_load constant for musl/aarch64.
  libc 0.2.185 omits the symbol from its musl/aarch64 bindings, so the
  supervisor's seccomp filter previously failed to compile for that target.
- architecture/build.md: describe the native-first pipeline and per-image
  runtime choices.

Local validation: gateway image 101MB (was 194MB), supervisor image 21.7MB.
helm:skaffold:run deploys cleanly; the static musl supervisor binary runs
correctly in a non-glibc agent container.

* refactor(docker): tighten binary perms via --chown + 0550

Replace `COPY --chmod=755` with `COPY --chown=<user> --chmod=0550` in
the gateway and supervisor Dockerfiles. The binary is no longer
world-readable or world-executable; ownership is pinned to the runtime
user.

- Gateway uses `--chown=nvs:nvs` + `USER nvs:nvs`, matching the only
  non-root user defined in `nvcr.io/nvidia/distroless/cc` (UID 1000) and
  the Helm chart's `securityContext.runAsUser: 1000`, which overrides
  the Dockerfile USER at runtime.
- Supervisor uses numeric `--chown=65534:65534` because the scratch base
  has no `/etc/passwd` for name resolution. The supervisor image is
  only consumed by the init-container copy-self path; the destination
  pod's runAsUser governs execute access.

Validated by deploying to a local k3d cluster via `helm:skaffold:run`
and confirming the gateway StatefulSet reaches 1/1 Running.

* ci(gpu): repoint GPU probe image lookup at Dockerfile.gateway

The previous awk parsed `FROM <image> AS gateway` from the now-deleted
`Dockerfile.images`. The new `Dockerfile.gateway` uses an ARG with a
default (`ARG GATEWAY_BASE_IMAGE=nvcr.io/nvidia/distroless/cc:v4.0.4`)
and `FROM ${GATEWAY_BASE_IMAGE} AS gateway`, so the old script returns
nothing.

Parse the ARG default value directly so the GPU prerequisites check
keeps using the gateway base image as a `nvidia-smi` probe target.

* ci(gpu): pin GPU probe to nvcr.io/nvidia/base/ubuntu:noble

The previous probe parsed the gateway base image out of the Dockerfile,
relying on the fact that the gateway ran on `nvcr.io/nvidia/base/ubuntu`
and that NVIDIA Container Toolkit CDI injection would populate
`nvidia-smi` and the supporting libs at runtime. The new gateway base
(`nvcr.io/nvidia/distroless/cc`) lacks `ldconfig`, a populated
`/usr/bin`, and the broader filesystem layout CDI injection assumes,
so it cannot serve as a GPU probe.

Pin the probe image explicitly to the NVIDIA-managed Ubuntu base. The
probe is independent of the gateway runtime and survives future base
swaps.

* fix(e2e-gpu): pass GPU probe image via env, drop Dockerfile.images parse

The Rust e2e test `gpu_request_for_each_discovered_device_matches_plain_container`
was still parsing the deleted `Dockerfile.images` to derive its GPU probe
image, panicking with `No such file or directory` after this PR's
Dockerfile split.

Move the probe image to a single source of truth in the workflow
(`OPENSHELL_E2E_GPU_PROBE_IMAGE` env at the job level) and require the
e2e test to read it from there. No silent codebase default — the test
panics with a pointer at the workflow if the env is missing, so it
fails loudly rather than drifting from CI.

The prereq probe step in the workflow now consumes the same env, so
the probe image is declared exactly once.

* fix(docker): keep supervisor binary root-owned for rootless Podman

The Podman driver mounts the supervisor image read-only into the sandbox
container at /opt/openshell/bin and runs that container as UID 0, but
deliberately drops DAC_OVERRIDE for hardening (container.rs:419). With
--chown=65534:65534 --chmod=0550 the binary was r-xr-x--- owned by UID
65534, so the container's UID 0 fell into "other" with no read or exec
access and the supervisor crashed on start (ContainerExited code 1).

Docker and Kubernetes both retain DAC_OVERRIDE, so root could still
exec the file — which is why this regression only surfaced in the
Podman e2e job.

Drop --chown from the supervisor COPY so the binary stays root-owned.
Keep --chmod=0550: the security win was dropping world-execute, not
changing the owner. The chown bought nothing here because the container
is always UID 0 regardless of driver, but it actively broke the only
driver that drops DAC_OVERRIDE.
