The credential driver e2e has not passed end to end, and the disabled
kubernetes-credential-drivers CI lane hid three problems.
The test broke when the JSON format of provider list changed.
Continuation-token pagination (#3249) changed
provider list --output json from a bare array of providers to an object
with next_page_token and a providers array. The test still parsed the
output as an array, so it failed before checking either storage
backend. Read the providers array from the new object instead.
Its sandbox name was about 58 characters, but sandbox names are
DNS-routable and limited to 19, so sandbox creation was rejected. Build
a short unique name instead.
The sandbox guard deletes its sandbox from a detached thread on drop, so
the test deleted the provider while the sandbox still existed. The
gateway rejects deleting a provider that is attached to a sandbox, the
test ignored that error, and the credential Secret remained. Delete the
sandbox explicitly before returning from the sandbox check.

* fix(sandbox): fall back to plain seccomp listener when WAIT_KILLABLE_RECV is unavailable
SECCOMP_FILTER_FLAG_WAIT_KILLABLE_RECV was added in Linux 5.19. On older
kernels (for example RHEL 9.x / 5.14 nodes such as RHCOS on OpenShift) the
flag is rejected with EINVAL, which made the capability-free sandbox fail to
start during the notification probe with "notification launcher disappeared".
Install the notification listener with WAIT_KILLABLE_RECV when the kernel
supports it and fall back to a plain NEW_LISTENER on EINVAL. The fallback
listener records wait_killable_recv = false: its notification receive is
uninterruptible, but the sandbox is otherwise fully functional.

* fix(sandbox): address review — legacy read-only listener mode + cancellation invariant
Follow-up to the PR review (GATOR-de00bfcc-01 / mrunalp): make the < 5.19
fallback cancellation-safe instead of racing broker writes.
- Record an explicit ListenerMode (Killable vs LegacyReadOnly); add
writes_disabled()/mode() and emit the selected mode in qualification output
(seccomp_listener_mode).
- Centralize task-memory output writes behind NotificationListener::
write_task_output; in LegacyReadOnly mode getpeername, accept/accept4 with a
non-null address, and sendmmsg length write-backs fail closed with EOPNOTSUPP.
accept with a null address, socket/connect/bind/listen/sendto/sendmsg keep
working (copied inputs, scalar responses, atomic ADDFD_SEND).
- Enforce the launch invariant `cancellation || task_memory_writes_disabled` in
SandboxConfirmEvidence::validate() rather than dropping cancellation
unconditionally; add task_memory_writes_disabled to SeccompEvidence.
- Add per-path fail-closed tests (write_task_output, write_socket_addr, a real
plain listener installed on a modern kernel) and confirmation-invariant tests.
- Correct the flag-semantics comments and document both modes plus the reduced
legacy syscall compatibility in architecture/sandbox.md.

Allocate cursors from a single SeqAllocator shared by the log and

* feat(server): serve WatchSandbox resume from cursor with gap detection
Add tail_after() to the log and platform event buses, returning every

tracks last_trimmed_seq (the highest seq it has evicted) so a resume is
reported as an unrecoverable ResumeGap only when this bus dropped an
event the client still needs.
Judging gaps by evictions, not by the tail's oldest seq, is required
under the shared cursor space: each bus's tail is non-contiguous in the
global sequence because the other bus owns the missing seqs, so
comparing against tail.front() would flag false gaps.

* feat(kubernetes): support corporate proxy CA bundle
The Kubernetes driver had no way to supply a CA bundle for the corporate
egress proxy, so an `https://` proxy with a private CA, or a TLS-intercepting
proxy, could not be used. Podman and VM already expose `proxy_ca_bundle`.
Add `proxy_ca_bundle` to `[openshell.drivers.kubernetes]` as a path the
gateway Pod reads. The gateway stages the PEM into the existing
per-generation supervisor bootstrap Secret and passes
`--upstream-proxy-ca-bundle` on the supervisor argv. That Secret is already
immutable, owner-referenced and garbage-collected, and its volume mounts
every key at /.openshell/supervisor with no items filter, so this needs no
new object kind, volume, mount, or RBAC verb, and works in shared, managed
and operator workspace modes.
The bundle is deliberately read from the gateway's filesystem rather than
referenced as an object in the sandbox namespace. It becomes a trust anchor
for every upstream the sandbox reaches, so it must stay in the gateway's
trust domain; the immutable staging Secret also keeps the anchor from
changing underneath a running sandbox.
Bound the staged bundle at 256 KiB. The shared reader's limit is exactly the
apiserver's own Secret limit and the bootstrap Secret carries four other
keys, so a bundle between the two would pass gateway startup and then fail
every sandbox create with an opaque `data: Too long`.
Delegate the URL, no_proxy, connect_by_hostname and ca_bundle rules to the
shared validate_upstream_proxy_settings, keeping the Secret-specific
credential block local: this driver accepts an explicit
`proxy_auth_allow_insecure = false` without credentials, which the shared
rules reject. This also fixes the acknowledgement being demanded for an
`https://` proxy, where the credential travels inside the verified TLS
session. Add auth_setting_label so the inline-credential diagnostic names
the Secret keys instead of proxy_auth_file, which this driver rejects as an
unknown key.
Document that the bundle should carry only the CA that signs the proxy's
certificate, or that an intercepting proxy re-signs upstream certificates
with. Public roots already reach the sandbox through the supervisor image and
its TLS stack, and the bundle is concatenated with that system store into a
single boundary control frame, so a full merged trust bundle spends the frame
budget on duplicated roots. The frame, not the apiserver Secret limit, is the
tighter of the two ceilings in practice; raising the staging bound requires
checking it.

The opt-in glibc-static supervisor variant from #2682 is gone: the Nix
release builds (#2977) removed it from CI and the supervisor Dockerfile,
and the RFC 0012 sandbox split (#2942) removed it from the staging script.
The split also moved the binary that runs inside workload images to
openshell-sandbox; the supervisor now runs from its own image and is
dynamically linked. A few places still describe the old model:
- skills/debug-openshell-cluster told operators to check that
supervisor_image contains a static /openshell-supervisor. Ask instead for
a supervisor from the matching release whose loader and shared libraries
are available inside that image, and give a `--version` check that shows
both. The static requirement for /openshell-sandbox is unchanged.
- verify-static-binary.sh justified its check with the supervisor and the
glibc-static variant. Describe the property it enforces instead, with
the musl sandbox runtime as the main example.
- stage-prebuilt-binaries.sh kept an unreachable gnu-static case in
target_triple.
No behavior change: resolve_component only ever selects gnu or musl.

* perf(server): cache peer connections, tokens, and owner lookups
Every forwarded relay rebuilt its setup from scratch: an owner lookup, a
blocking read of the peer token, a TLS connect to the owning replica, and
a TokenReview plus Pod GET on the receiving side. Sandbox service routing
does this per HTTP request, so the apiserver calls scaled with traffic.
Cache all of it on ServerState:
- peer channels pooled per endpoint, so relays multiplex over one
connection instead of redialing
- peer tokens keyed by SHA-256, expiring at min(ttl, token exp) so a hit
cannot accept an expired token
- owner records for 3s against a 45s ownership TTL, still freshness
checked before use
Entries are evicted when a relay fails. Also raise HTTP/2
max_concurrent_streams to 1024, since pooling funnels every relay between
two replicas onto one connection and hyper's default of 200 sits below
the 256 pending-relay budget.

* perf(server): pool upstream connections for sandbox services
Each HTTP request to a sandbox service opened its own supervisor relay,
paying a new TCP connection and HTTP/1 handshake every time. Worse, it
counted against the 32 in-flight relay cap, so a service handling more
than 32 concurrent requests failed outright.
Pool idle upstreams per endpoint and port, up to 8 each for 15s. Reuse is
safe because the pool only returns a connection hyper reports as ready,
and HTTP/1 cannot start a request until the previous body has drained.
Upgrades are never pooled since they take the connection over, and a
failed send evicts that endpoint. Pruning is bounded per key, with the
full sweep limited to once per 30s.

* fix(server): address HA gateway review findings (#3449)
- Let a gateway own supervisor sessions without a peer endpoint. Requiring
one whenever the store is PostgreSQL broke every single-instance
PostgreSQL deployment, because no sandbox supervisor could connect.
A cross-replica request to an owner that advertises no endpoint now fails
immediately naming the cause, instead of retrying until the wait timeout.
- Close a supervisor session on heartbeat only when another replica owns it,
or after renewals fail for the ownership TTL. A database error no longer
drops every session heartbeating during an outage.
- Clamp owner record ages at zero so a skewed or corrupt stored timestamp
cannot produce a negative age.
- Bound the cross-object advisory lock with a lock timeout, so a stuck holder
fails instead of blocking every mutation in the fleet.
- Refuse to start when a peer endpoint is configured on a multi-replica
backend but peer authentication is unavailable, and warn when a
multi-replica backend has no peer endpoint at all.
- Reject a plaintext peer endpoint when the gateway serves TLS.
- Skip the sandbox watch poller on single-replica backends, where the local
update bus already sees every write.
- Rate-limit the peer owner cache sweep so an insert no longer scans the
whole map under the lock.
- Retry GET and HEAD on a pooled upstream the sandbox closed, instead of
returning 502, and drop an emptied endpoint from the pool right away.
- Document the gateway peer environment variables and the post-rollout
ownership skew operators should expect.

* fix(vm): unpack registry images correctly and validate prepared disks
The registry image-prep path expected `umoci raw unpack` to produce a
bundle-style rootfs/ subdirectory, but it extracts the image filesystem
directly into the target. Every registry prep therefore failed after a
successful unpack. Guest init exit codes do not survive the libkrun
boundary, so the failure looked like success and the broken disk was
cached, making every later sandbox for that image fail with "prepared
image disk missing /image-rootfs".
VM E2E started hitting this after the bootstrap image moved to
nvcr.io/nvidia/base/ubuntu:24.04: `--from base` no longer matches the
bootstrap image, so it now goes through registry prep.
- Accept umoci's direct extraction layout in the guest prep script.
- Build the image rootfs under a partial directory and rename it to
/image-rootfs only after every prep step succeeds.
- Check the prepared disk for /image-rootfs before caching it. On
failure, leave the cache untouched and report the prep console tail.
- Size the prep disk to hold the payload and the unpacked rootfs at the
same time. The community base image needs 1.40 GB + 3.32 GB, which
did not fit in the old payload*3 + 512 MiB.

Previously, Network Activity could be constructed without a source or

events to violate the OCSF 1.8 endpoint constraint.
Now, NetworkActivityBuilder requires a source or destination endpoint at
compile time. Connection failures identify the workload peer or genuine
transparent destination, listener failures identify the listening endpoint,
and mediation-lane failures use Application Lifecycle rather than fabricated
network endpoints. Malformed forward requests use HTTP Activity with a
method-only request, generated 400 response, and workload peer.
Additionally, Unix relay-channel events use Base Event, policy-validation
warnings use Config State Change, and the unused bypass monitor is removed
