Yasar Rahman 8be7fb2e66 feat(redis): expose min-replicas-to-write and min-replicas-max-lag
Lets an operator bound the writes lost when an isolated Redis master is
failed over: the master refuses writes while fewer replicas than
configured are connected and recent. Both values are unset by default, so
the rendered Redis config is unchanged.

Redis treats 0 in either directive as disabling the check, so the
chart refuses minReplicasMaxLag 0 next to a replica requirement
instead of silently turning the protection off.

Negative values are refused by the schema (minimum 0), since Redis
rejects them at CONFIG SET and the operator would stop healing the
Sentinels of that instance. A requirement of replicas or more is
refused at render: a master with replicas pods has replicas-1
replicas, so it would refuse every write for good.

Aleksei Sviridkin 33ca8b67bb feat(redis): run Sentinel on the same image as the Redis pods (#4831)
## What this PR does

The Redis application pins its Sentinels to `redis:6.2.6-alpine`
(`packages/apps/redis/templates/redisfailover.yaml`), while the data
pods run the version selected by `version` (`redis:8.4.0` for `v8`,
`redis:7.4.7` for `v7`). The pin was added in fde96dd7d so that the
freshworks-oss operator's new compiled-in default (`redis:7.2.4-alpine`)
could not move the Sentinels silently on upgrade, and its comment asks
for the bump to be made as a deliberate, separate change. This is that
change.

Redis 6.2 is end of life, and today every instance runs a Sentinel one
or two major versions behind the Redis it monitors. With this change
`spec.sentinel.image` is rendered from the same `files/versions.yaml`
entry as `spec.redis.image`, so a `v8` instance runs Redis and Sentinel
on `redis:8.4.0`, and a `v7` instance on `redis:7.4.7`. Nodes then pull
one engine image per instance instead of two.

The rollback concern behind the original pin was dump.rdb compatibility.
It does not apply to Sentinel: a Sentinel pod stores no RDB or AOF, only
a `sentinel.conf` on an `emptyDir` that the operator's
`sentinel-config-copy` init container rewrites from the operator
ConfigMap on every pod start. Rolling back the chart therefore starts
the older Sentinel image from a clean config. The image stays explicit
in the rendered RedisFailover, so an operator upgrade still cannot move
it.

Changes:

- `templates/redisfailover.yaml`: `spec.sentinel.image` uses
`redis.versionMap`, with the comment rewritten to say why it is pinned
and why a rollback is safe.
- `values.yaml` and `hack/update-versions.sh`: the `version` description
says that Redis and Sentinel run the same image (`update-versions.sh`
rewrites that line on `make update`, so it carries the same text).
`README.md`, `values.schema.json`, `api/apps/v1alpha1/redis/types.go`
and `packages/system/redis-rd/cozyrds/redis.yaml` are the `make
generate` output for that description.
- `tests/sentinel_image_test.yaml`: new helm-unittest suite; it asserts
that the Sentinel and Redis images share the major version for `v8` and
`v7`. The patterns pin the major version only, so a patch bump in
`files/versions.yaml` needs no test change.
- `hack/e2e-chainsaw/redis/chainsaw-test.yaml`: comment only. It
described the Sentinel container's `timeout` as busybox (exit 143); the
Sentinel now runs the Debian-based image with coreutils (exit 124). The
checks only read "non-zero", so behaviour is unchanged.

Upgrade behaviour: on the first reconcile after the upgrade, every Redis
instance rolls its Sentinel Deployment once (the operator does not set a
strategy, so the default `maxSurge: 1`, `maxUnavailable: 0` applies to 3
replicas). A new Sentinel pod starts from the initial config, the
operator points it at the current master (`NewSentinelMonitor`, which
also sets `auth-pass`), and only then does it pass the readiness probe
that lets the next old pod go. The data pods are not touched.

Not changed: Harbor's Redis
(`packages/system/harbor/templates/redis.yaml`) keeps both images on
`redis:6.2.6-alpine`. Its data pods are PVC-backed, so the rollback
concern still applies there and it needs its own decision.

Testing done:

- `make generate` in `packages/apps/redis`: regenerated files committed;
a second run leaves no diff.
- `make test` in `packages/apps/redis` (helm-unittest v1.1.2): 50
passed. With the template change reverted, the 2 new tests fail and the
other 48 pass.
- `helm template` with `version=v8` and `version=v7`:
`spec.sentinel.image` and `spec.redis.image` are both `redis:8.4.0` and
both `redis:7.4.7` respectively.
- `helm lint` reports the same two errors as on `main` (icon URL,
`cozy-lib` not declared as a dependency), so nothing new.
- I checked the operator's Sentinel command set (`SENTINEL
REMOVE/MONITOR/SET auth-pass/SET
down-after-milliseconds/RESET/CKQUORUM/MASTER`, `INFO sentinel`) against
a Redis 8.6.2 Sentinel locally. It behaves the same as on 6.2. I have
not run the e2e suite. On a Cozystack v1.6.4 cluster we run Redis 8.4.0
data pods with 6.2.6 Sentinels today, but not this exact chart.

Backwards compatibility: no API change. Existing instances roll their
Sentinels once, as described above. Rolling the chart back rolls the
Sentinels back to `redis:6.2.6-alpine` with a fresh config.

Trigger map walked against the diff: the only user-visible text change
is the `version` description in `values.yaml`/`README.md`. `redis` is in
the website `Makefile` `APPS` list, so the release bot regenerates its
page. No field, enum, default or name changes, so
terraform-provider-cozystack is not affected.

### Release note

```release-note
feat(redis): Sentinel pods now run the same Redis image as the data pods (redis:8.4.0 for v8, redis:7.4.7 for v7) instead of the end-of-life redis:6.2.6-alpine. Existing instances roll their Sentinels once on upgrade; data pods are not restarted.

Ray Low 904bc38fc3 fix(kubernetes): delete the Talos PKI and oidc-bootstrap Job on uninstall
cert-manager runs with enableCertificateOwnerRef: false, so the
<release>-talos-ca and <release>-talos-tls-cert Secrets carry no
ownerReference to their Certificates and outlive the release, keeping
the CA private key of a cluster that no longer exists. A new cluster
created under the same name then adopts that stale CA instead of
issuing its own trust root.

The <release>-oidc-bootstrap Job is a hook whose only delete policy is
before-hook-creation. Hooks are not part of the release manifest, so
uninstall never removes it.

The pre-delete hook deletes the two Certificates before their Secrets,
because deleting a Secret while its Certificate exists makes
cert-manager re-issue it. It runs after the TenantControlPlane is gone,
since the control plane's CSR signer mounts the CA. The Role grants
each delete by resourceName only.

Yasar Rahman 9a88afe6ca feat(redis): run Sentinel on the same image as the Redis pods
The Sentinels were left on redis:6.2.6-alpine when the operator moved to
the freshworks-oss fork, so that its new compiled-in default could not
move them on upgrade. 6.2 is end of life, and every instance now runs a
Sentinel one or two major versions behind the Redis it monitors.

The rollback risk behind that pin, a newer engine rewriting dump.rdb in
a format the older one cannot load, does not apply to Sentinel. It
stores no RDB or AOF, only sentinel.conf on an emptyDir that the
config-copy init container rewrites from the operator's ConfigMap on
every start, so moving back to an older image starts from a clean
config. Taking the image from the same version map as the data pods also
means one image per node instead of two.

The e2e comment that relied on busybox's timeout exit code in the
Sentinel container is updated, since that container now carries
coreutils.

Aleksei Sviridkin df2e1c33e1 feat(kubernetes-nodes): build the Proxmox worker template from the pool's Talos values (#4742)
## What this PR does

A `substrate: proxmox` pool clones its workers from a VM template the
chart never sees: capmox selects it by `proxmox.templateTags`, and the
pool's `talos.*` values reach only the installer written into the worker
machineconfig. Nothing in the repository says which image that template
has to carry, and the image an operator reaches for is the wrong one:

- The release asset `nocloud-amd64.raw.xz` is built from
`packages/core/talos/images/talos/profiles/nocloud.yaml`, the bare-metal
node image. Its `zfs` extension starts `ext-zfs-service`, which waits
for `/dev/zfs`. A VM never has it, so `startAllServices` never finishes,
and Talos fails the boot sequence and reboots the guest each time the
boot timeout runs out. On our v1.13.6 stand that was every ~70 minutes,
visible in the tenant only as `SandboxChanged` on every Pod (218 cilium
restarts in 12 days); from the Proxmox side the VM never restarts. The
same profile also follows the host nodes' Talos (v1.14.2 since
e002f8d5e), not the pool's `talos.version` (v1.13.6), so the boot image
and the installer the machineconfig names drift apart.
- The chart's default schematic `ce4c9805…` is not vanilla: it carries
`siderolabs/qemu-guest-agent`, whose service `depends` on
`/dev/virtio-ports/org.qemu.guest_agent.0`. Proxmox adds that port only
to a VM with the agent enabled, so a template built from the right image
with the agent off waits the same way.

`hack/proxmox-talos-template.sh` builds the template from the chart's
own `talos.version`, `talos.schematicID` and `talos.imageFactoryURL`, in
the nocloud flavour, with the agent enabled, and prints the `talos.*`
and `proxmox.templateTags` a pool selects it with. A pool that overrides
`talos.*` passes the same values through `COZY_TALOS_*`. Before
downloading anything it checks that the VMID is free cluster-wide and
that no other template carries the same tag set: capmox compares the
selector with each template's tags as a set and needs exactly one match
across the cluster, so a duplicate stops every pool that selects it with
`found 2 VM templates`. `print` writes the program that `create` runs as
root on the hypervisor, so it can be read first.

The layout (ovmf, `x86-64-v2-AES`, `virtio-scsi-pci`, serial console) is
the one the Proxmox substrate has been running on, minus the NIC: capmox
writes `net0` from `proxmox.network` on every clone. The disk defaults
to 20G because capmox clones it at the template's size; `diskSize` does
not reach a Proxmox worker.

Out of scope on purpose: building a worker image in
`packages/core/talos` for air-gapped installs. The template follows
`talos.imageFactoryURL`, so a self-hosted Image Factory already covers
that case.

Refs #3481.

### Also in this diff

- `nodegroup.yaml`: the comment on the template selector says which
image the template carries, and the comment on `checks` no longer says
Talos never ships qemu-guest-agent.
- The `proxmox.templateTags` description points at the script and warns
off the release asset; README, `values.schema.json`, the CRD and
`types.go` are regenerated.

### Testing

- `hack/cozytest.sh hack/proxmox-talos-template_test.bats`: 12/12,
against stubs of `ssh`, `pvesh`, `qm`, `curl` and `xz`. It goes red on
each of `agent enabled=0`, a disabled duplicate-tag check, and
`openstack-amd64` in place of `nocloud-amd64`.
- `make -C packages/apps/kubernetes-nodes test`: 206/206, snapshots
unchanged.
- `make generate` at the root and in the package: no further diff.
- Not yet run against a live Proxmox. It will build the replacement for
our stand's template, which was made from the release asset. The
qemu-guest-agent half is derived from the extension's `depends` and the
zfs case observed there, not observed on its own.

### Screenshots

Not applicable, no UI change.

### Downstream repositories

- [x] No downstream repository is affected by this change

`kubernetes-nodes` has no generated page on the website (it is in none
of the website `Makefile` app lists, and no page mentions the Proxmox
substrate), the only schema change is a field description, and `hack/`
gains a file without moving or renaming one.

### Release note

```release-note
feat(kubernetes-nodes): add `hack/proxmox-talos-template.sh`, which builds the Proxmox VM template a `substrate: proxmox` pool clones from the pool's own `talos.version` and `talos.schematicID` in the nocloud flavour, with the guest agent the default schematic needs. Do not build that template from the release's `nocloud-amd64.raw.xz`: it is the bare-metal node image, and its zfs extension keeps a VM worker from finishing its boot, so Talos reboots it at every boot timeout.
```

* **New Features**
* Added a utility to generate or create Proxmox Talos VM templates using
Kubernetes-nodes chart settings. It validates template options, supports
local or SSH-based creation, and displays pool configuration after
successful creation.
* Kubernetes node pool configuration now accepts kernel module names and
optional parameters.
* **Documentation**
* Clarified that Proxmox templates must match the pool’s Talos version
and schematic, use the nocloud flavor, and have the guest agent enabled.
The bare-metal image is unsuitable and may prevent VMs from completing
boot.
  * Added guidance on NVIDIA module selection and pool rollouts.

Aleksei Sviridkin 1d813c9445 fix(backups): refuse concurrent restores and skip the CNPG purge only for this restore's Cluster (#4754)
## What this PR does

Fixes #3322. An in-place Postgres (CNPG) restore decided whether to skip
deleting the live `Cluster` by comparing its `creationTimestamp` with
the RestoreJob's `StartedAt`. The timestamp says the Cluster is new, not
which restore rendered it, so two cases let a restore skip its purge and
report `Succeeded` on data from another restore:

1. Two RestoreJobs into the same application at once. The second sees
the Cluster the first produced, created after its own `StartedAt`, and
skips its purge.
2. The live Cluster is deleted while the restore waits for the WAL
archive. The still-active HelmRelease re-renders it from the previous
restore's values, again created after `StartedAt`.

### Refuse a restore into an application another restore holds

The RestoreJob controller now refuses, for every driver, a RestoreJob
that has not started yet when another unfinished RestoreJob in the
namespace writes into the same application and goes first. The refused
job fails with reason `ConcurrentRestore`, and its message names the job
that goes first. It fails instead of waiting, so the application is
never restored a second time later, after the first restore, by a job
its author may no longer expect to run.

A started restore goes before one that has not started. Between two that
have not, the older goes first, by creation time and then by name;
creation times have one-second precision, so two jobs created in the
same second are ordered by name. A running restore is never failed by a
newer one. The target application is resolved by `restoreJobTarget`, the
same helper the BackupJob hold uses, so a Velero restore into another
namespace does not collide with an in-place one.

The gate lists RestoreJobs through the manager's API reader, not the
informer cache. A job reconciled before the cache holds its peer's
`StartedAt` would otherwise see that peer as not started and, on a
same-second name tie, proceed alongside it. The controller runs a single
worker, so a peer's `StartedAt` written by an earlier reconcile is
already on the API server when the next job reads it; `SetupWithManager`
now sets `MaxConcurrentReconciles: 1` explicitly, since the guarantee
depends on it.

### Skip the CNPG purge only for this restore's Cluster

The restore patch already sets `bootstrap.newServerName` to
`restoredServerName(cluster, RestoreJob UID)`, a value unique to each
RestoreJob. The postgres chart now annotates the `Cluster` with it as
`postgres.cozystack.io/restored-server-name`. The annotation is rendered
even when the barman plugin is not; the plugin's `serverName` also
carries the value, but the plugin renders only with chart-level S3
coordinates. The driver skips the purge only when the annotation names
this RestoreJob. A Cluster produced by a concurrent restore, or
re-rendered from an earlier restore's values, carries another value and
is purged.

The mark lives on the rendered Cluster rather than in RestoreJob status.
That keeps it valid in the case the skip exists for: the purge
succeeded, but the `TargetPurged` status write failed. A UID recorded in
status was rejected in the code for exactly that reason. A Cluster
rendered by a chart that predates the annotation has none and keeps the
creation-time check, so a restore in flight across an upgrade behaves as
before.

### Tests

- `TestRestoreAhead` covers order, a started job going first, the name
tie-break, finished and terminating jobs, other applications, retargeted
restores and a Velero restore into another namespace.
- `TestReconcileRestore_ConcurrentRestoreIsRefused` checks that the
newer job fails with `ConcurrentRestore` and the running one is left
alone.
- `TestReconcileRestore_ConcurrentRestoreReadsPastTheCache` gives the
cache a stale, not-started peer and the API reader the started one, and
requires the job to fail with `ConcurrentRestore`.
- `TestCNPGClusterFreshlyRecovered` adds both cases from the issue: a
Cluster marked by another restore and created after `StartedAt` must be
purged. The timestamp-only cases are kept for the unmarked fallback.
- `TestReconcileCNPGRestore_RepeatInPlacePurgesStaleRecoveryCluster`
gains two reconcile-level cases. One purges a Cluster that another
restore marked, even though it was created after `StartedAt`. The other
runs a full purge, takes the mark from the `bootstrap.newServerName` the
restore patch wrote, drops `TargetPurged` as a lost status write would,
and requires a Cluster carrying that mark to survive, although it
predates `StartedAt`. That pins the purge decision to the value the
chart actually renders.
- `packages/apps/postgres/tests/restore_mark_test.yaml` checks that the
annotation is rendered with and without the barman plugin, and is absent
on a Cluster that was never restored.

Each new test was checked against the code it guards: disabling the gate
call, listing through the cache, flipping the started-job precedence,
ignoring the annotation, or deriving the expected mark from the app name
instead of the cluster name each turns one red. `go test
./internal/backupcontroller/...` and `helm unittest
packages/apps/postgres` (152 tests) pass. The restore flow was not run
against a live cluster.

`docs/operations/backup-classes.md` documents the one-restore-at-a-time
rule and the annotation.

### Screenshots

N/A — no UI changes.

### Downstream repositories

Walked the trigger map in `docs/agents/contributing.md` against the
diff: Go changes in `internal/backupcontroller` (no CRD or API type
change), one annotation added to the postgres chart's Cluster (no
`values.yaml` or `values.schema.json` change), and a docs paragraph. No
package is added or renamed, no platform values, ApplicationDefinition,
RestoreJob CRD, metric, label or namespace changes, so no trigger is
reached.

## Summary by CodeRabbit

* **New Features**
* Restores targeting the same application are now handled one at a time.
A competing restore is refused rather than queued, with started restores
taking priority.
* PostgreSQL now calculates a default `shared_buffers` value when the
memory limit is below 512 MiB, while respecting explicitly configured
values.
* **Bug Fixes**
* Recovery clusters are more reliably distinguished from manual
recoveries and clusters created by other restores, reducing the risk of
purging the wrong cluster.
* **Documentation**

Aleksei Sviridkin f093273736 feat(redis): size the Sentinel pods separately from Redis (#4832)
## What this PR does

The Redis application renders `spec.sentinel.resources` from the same
`resources`/`resourcesPreset` pair as the Redis pods. Every instance
runs three Sentinels, so it reserves three extra copies of a Redis
replica's memory for processes that hold only their configuration and
the failover state. The dataset that drives the Redis sizing never
reaches a Sentinel.

On our Cozystack v1.6.4 staging cluster, an HA Redis on `t1.nano`
reserves 3 x 128Mi for its Sentinels. The VPA recommender
(recommendation mode only) gives an uncapped target of 16Mi for the
`sentinel` container. On a `u1.small` instance the same three Sentinels
would reserve 3 x 4Gi.

This PR adds an optional `sentinel` block with the same two keys the top
level has:

```yaml
resourcesPreset: u1.small
sentinel:
  resources:
    cpu: 100m
    memory: 64Mi
  # resourcesPreset: t1.nano
```

Resolution rules:

- `sentinel` empty (the default): the Sentinels keep the Redis sizing
(`resources` + `resourcesPreset`). Existing instances therefore render
exactly as before and an upgrade does not roll their Sentinels.
- `sentinel.resourcesPreset` set: the Sentinels use that preset.
Explicit top-level `resources` are not carried over, since they were
sized for the dataset.
- `sentinel.resources` set: it wins. Any key it leaves out is filled
from `sentinel.resourcesPreset`, which falls back to `resourcesPreset`.
- The Sentinel `WorkloadMonitor` label
`workloads.cozystack.io/resource-preset` now carries the preset the
Sentinels actually use. The Redis `WorkloadMonitor` is unchanged.

Changes:

- `values.yaml`: new `Sentinel parameters` section (`@typedef Sentinel`,
`@param {Sentinel} [sentinel]`, default `{}`), reusing the existing
`Resources` and `ResourcesPreset` types so the enum and quantity
validation is the same as the top-level pair.
- `templates/redisfailover.yaml`: computes the Sentinel preset and
resources once and uses them for `spec.sentinel.resources` and the
Sentinel `WorkloadMonitor` label.
- `README.md`: generated table rows plus a short hand-written `sentinel`
section next to `resources and resourcesPreset`.
- Generated: `values.schema.json`, `api/apps/v1alpha1/redis/types.go`
(new `Sentinel` struct, `ConfigSpec.Sentinel`),
`api/apps/v1alpha1/redis/zz_generated.deepcopy.go`,
`packages/system/redis-rd/cozyrds/redis.yaml`.
- `tests/sentinel_resources_test.yaml`: 10 helm-unittest cases covering
the rules above and an unknown preset being refused.

I chose not to change the default sizing. A smaller default (for example
a fixed small preset for Sentinel) would save more for everyone, but it
would also roll every instance's Sentinels and change what tenants are
billed for on upgrade. If maintainers prefer that, it is a one-line
follow-up on top of this change.

Testing done:

- `make generate` in `packages/apps/redis` with cozyvalues-gen v1.7.0
(the version `pre-commit.yml` installs); regenerated files committed.
- Deepcopy: `controller-gen object` v0.16.4 on `api/apps/v1alpha1` (the
last step of `hack/update-codegen.sh`), only the redis package changed;
`go build ./...` and `go vet ./redis/` pass in that module, `go mod
tidy` leaves no diff. I could not run the full root `make generate` on
my machine: code-generator v0.37.1 fails to parse the Go 1.27.1 standard
library (`math/rand/v2: method must have no type parameters`), which is
a host toolchain problem unrelated to this change. CI's `codegen-drift`
job should confirm.
- `make test` in `packages/apps/redis` (helm-unittest v1.1.2): 58
passed. With the template change reverted, 4 of the new cases fail (the
ones that set `sentinel.*`); the cases that pin today's behaviour pass
both ways.
- Rendered output with no `sentinel` block is identical to `main` (all
documents except the random-password Secret) for the defaults,
`resourcesPreset=u1.small`, and explicit `resources` (cpu 1, memory
2Gi).

Backwards compatibility: purely additive. The field is optional with an
empty default, existing instances render unchanged, and nothing rolls on
upgrade. Clients that do not know the field are unaffected.

### Screenshots

Not a UI change. The dashboard form gets a `sentinel` object from the
schema like other nested parameters (e.g. `tls`).

Trigger map walked against the diff: this adds a field to
`values.schema.json`, so `cozystack/terraform-provider-cozystack` needs
to model `sentinel.resources` / `sentinel.resourcesPreset` in its Redis
resource. I will open that issue once this PR has a number and link it
here; a draft is in `FOLLOWUP-terraform-provider-redis-sentinel.md`. The
website page for `redis` is regenerated from `README.md` by the release
bot (`redis` is in the website `APPS` list), so no manual follow-up
there. Nothing else in the map is touched.

### Release note

```release-note
feat(redis): new optional `sentinel.resources` and `sentinel.resourcesPreset` parameters size the three Sentinel pods independently of the Redis pods. When unset, Sentinels keep the Redis sizing as before, so existing instances are unchanged.
```

## Summary by CodeRabbit

* **New Features**
* Added independent CPU and memory resource settings and sizing presets
for Redis Sentinel pods.
* When Sentinel-specific settings aren’t provided, Sentinel pods inherit
Redis resource settings. Unspecified Sentinel resource values can use
the Sentinel preset, which defaults to the Redis preset.
* Added configuration documentation and validation for Sentinel resource
settings.

Marian Koreniuk bbd39c94a4 feat(kubernetes-nodes): build the Proxmox worker template from the pool's Talos values
A proxmox pool clones its workers from a VM template the chart never sees,
and nothing said which Talos image that template has to carry. The one an
operator reaches for, the platform release's nocloud-amd64.raw.xz, is the
bare-metal node image: its zfs extension's service waits for a /dev/zfs no
VM has, the boot sequence never completes, and Talos reboots every worker
each time the boot timeout runs out, about every 70 minutes on v1.13. It
also follows the host nodes' Talos version, not the pool's talos.version
that the installer in the worker machineconfig names.

The chart's default schematic has a trap of its own: its qemu-guest-agent
service waits the same way for the agent's virtio port, which Proxmox adds
only to a VM with the agent enabled.

hack/proxmox-talos-template.sh builds the template from the chart's
talos.schematicID and talos.version in the nocloud flavour with the agent
enabled, refuses a tag set another template already carries, because
capmox then finds two and clones neither, and prints the templateTags
that select it.

Aleksei Sviridkin 08ee470f6a fix(postgres)!: refuse plaintext sessions on external instances (#4847)
## What this PR does

CloudNativePG offers TLS on an external Postgres but does not require
it. Its built-in last `pg_hba` rule is `host all all all`, which matches
TLS and non-TLS connections alike, so a client outside the cluster that
connects with `sslmode=disable` gets an unencrypted session. The chart's
`tls.enabled` only decides whether the external hostname goes into the
certificate, so it cannot prevent this. This is #4619.

When `external: true`, the chart now renders `spec.postgresql.pg_hba`:

```yaml
pg_hba:
  - hostssl all all all scram-sha-256   # md5 on PostgreSQL 13, matching CloudNativePG's default rule
  - host all all all reject
```

CloudNativePG puts user rules after its fixed rules (`local` peer,
`streaming_replica` and pooler `cert`) and before its default `host all
all all` rule, and PostgreSQL uses the first matching rule, so the two
lines above make remote sessions TLS-only without touching replication
or the metrics exporter. See the CloudNativePG [`pg_hba`
section](https://cloudnative-pg.io/documentation/current/postgresql_conf/#the-pg_hba-section)
and the
[template](https://github.com/cloudnative-pg/cloudnative-pg/blob/v1.30.0/pkg/postgres/configuration.go)
for v1.30.0, the operator version the platform ships.

A new tri-state `tls.required` follows the same pattern as
`tls.enabled`: when omitted it follows `external`, `false` opts out,
`true` requires TLS on an in-cluster instance too. The issue is silent
on a switch; I added one because the change is breaking and a tenant
with a client that cannot do TLS needs a way back that does not mean
patching the operator's resources.

In-cluster clients: the pod network cannot be told apart from an
external client (the external Service uses `externalTrafficPolicy:
Local`, so the source IP is the client's), so the rules apply to every
remote client. The chart's init job connects to `<release>-rw` with
libpq's default `sslmode=prefer`, which already negotiates TLS, as do
the backup and monitoring paths that run inside the pod over the Unix
socket. Only clients that disable TLS explicitly are refused. In-cluster
instances with `external: false` are unchanged.

Changes:

- `templates/_tls.tpl`: `postgres.tls.required` helper.
- `templates/db.yaml`: renders `spec.postgresql.pg_hba` when required.
- `values.yaml`: `tls.required`, with the generated
`values.schema.json`, `README.md`,
`api/apps/v1alpha1/postgresql/types.go` and
`packages/system/postgres-rd/cozyrds/postgres.yaml`. The `Required`
deepcopy block in `zz_generated.deepcopy.go` is controller-gen v0.16.4
output.
- `README.md`: new "Refusing plaintext sessions" paragraph.
- `tests/pg_hba_test.yaml`: 10 helm-unittest cases.

Backwards compatibility: breaking for existing external instances whose
clients connect without TLS. The rules apply on the next reconcile. They
are refused until the client enables TLS or the instance sets
`tls.required: false`.

Testing done:

- `make generate` in `packages/apps/postgres` with cozyvalues-gen
v1.7.0; regenerated files committed.
- `helm unittest .` in `packages/apps/postgres`: 206 passed (25 suites),
10 of them new. I did not run it against a live cluster, so the `pg_hba`
ordering is taken from the operator source and docs rather than
observed.

### Screenshots

Not a UI change. The dashboard form gets a `tls.required` toggle from
the schema.

### Downstream repositories

I walked the trigger map against the diff and left every box empty so a
human decides. The nearest hit is the website's managed-apps reference
page for postgres, which a stable-tag bot regenerates from `README.md`;
the Terraform provider's postgres schema may also want the new
`tls.required` field.

### Release note

```release-note
fix(postgres)!: an external Postgres now refuses sessions that are not encrypted. The chart renders `hostssl` rules for all users and databases with scram-sha-256 (md5 on PostgreSQL 13, matching CloudNativePG's default rule) and rejects plain `host` connections, so a client using `sslmode=disable` is refused. The new `tls.required` value follows `external` by default; set it to `false` to keep accepting plaintext sessions.
```

Fixes #4619

## Summary by CodeRabbit

* **New Features**
* Added a `tls.required` setting for PostgreSQL instances. By default,
TLS is required for external instances and optional for others. You can
override this behavior to require encrypted connections for both
external and in-cluster clients, or allow plaintext connections for
external instances. Rendering fails if TLS is required while PostgreSQL
SSL is disabled.

Aleksei Sviridkin f0e3e17493 feat(kubernetes-nodes): let CDI trust a self-hosted Talos image factory (#3797)
## What this PR does

Adds `talos.imageFactoryCA` to the `kubernetes-nodes` chart, so CDI can
verify a Talos Image Factory served with a certificate from an internal
CA. Fixes #3796.

### The gap

`talos.imageFactoryURL` is documented for self-hosted factories and
mirrors in air-gapped, rate-limited or flaky-egress environments. Such
an endpoint is normally served by the organisation's own CA, and CDI,
which trusts only its system store, refuses the import with `x509:
certificate signed by unknown authority`. The DataVolume never completes
and no worker joins.

`DataVolume.spec.source.http.certConfigMap` exists for exactly this, but
the worker DataVolume in `templates/nodegroup.yaml` renders `url` alone
and no value reaches that field.

### The change

One optional value on the existing `talos` group of a `KubernetesNodes`
pool:

```yaml
talos:
  imageFactoryURL: "https://factory.example.com"
  imageFactoryCA: |
    -----BEGIN CERTIFICATE-----
    ...
    -----END CERTIFICATE-----
```

When set on an HTTP import path (the default and `osImage.factory`), the
chart renders a ConfigMap `<release>-talos-factory-ca` in the release
namespace and points the DataVolume's `source.http.certConfigMap` at it.
A pool on `osImage.builtin` clones a golden image, builds no HTTP source
and gets no ConfigMap. Empty, the default, renders nothing: `helm
template` with the field unset is byte-identical to `main`, so existing
pools keep their KubevirtMachineTemplate name. Setting the CA changes
that name, so the pool rolls once.

CDI appends the bundle to the system pool rather than replacing it
(`x509.SystemCertPool()` followed by `AppendCertsFromPEM` in
`pkg/importer/http-datasource.go`), so a publicly trusted endpoint keeps
verifying.

The PEM is taken inline rather than as a ConfigMap name because
`certConfigMap` must live in the DataVolume's namespace, and the
dashboard offers no way to create that object by hand.

### Fail-closed guards

The value lands verbatim in a ConfigMap that anything able to read the
namespace can read, so it must be complete PEM certificate blocks and
nothing else, and must never carry private key material. That includes
the realistic accident of `cat ca.pem key.pem` pasted into the field.
The rules now live in one shared helper, `cozy-lib.tls.validateCACert`,
which `cozy-lib.tls.caCertSecret` also calls instead of keeping its own
copy. The regexes are unchanged; the failure message names the caller's
field.

### Testing

-
`packages/apps/kubernetes-nodes/tests/talos_image_factory_ca_test.yaml`,
13 cases: unset renders nothing, set renders the ConfigMap and a
matching `certConfigMap`, whitespace-only counts as unset,
multi-certificate chains, the builtin path, and each guard on the input
that trips it.
- `packages/tests/cozy-lib-tests/tests/tls_validatecacert_test.yaml`, 6
cases for the shared helper, plus the existing `caCertSecret` tests
updated for the new message.
- `make generate` in the package: regenerated `values.schema.json`,
`README.md`, `api/apps/v1alpha1/kubernetesnodes/types.go` and the
`kubernetes-nodes-rd` definition are committed.

Not yet exercised end to end against a live internal factory.

### Not in this PR

`packages/apps/vm-disk/templates/dv.yaml` renders `source.http.url` with
the same gap. Left for a follow-up if this shape is accepted.

Not a UI change.

## Summary by CodeRabbit

* **New Features**
* Added an optional setting for providing PEM certificate authorities
trusted when importing worker OS images over HTTPS. This supports the
default image source and factory images, allowing imports from endpoints
that use certificates not already trusted by the system.
* Certificate authorities are provided as PEM certificate blocks; when
configured, they are used for HTTPS image imports. The setting defaults
to empty and has no effect on pools using built-in OS images.
* **Bug Fixes**
  * Invalid certificate input, including private keys, is rejected.

Andrey Kolkov e4e991e837 fix(backups): skip the CNPG restore purge only for this restore's Cluster
The in-place CNPG restore skips deleting the live Cluster when it
carries bootstrap.recovery and was created after the RestoreJob started,
taking that as "this restore's own purge and re-render produced it". The
timestamp does not say which restore rendered the Cluster. A Cluster
deleted while the restore waits for the WAL archive is re-rendered by
the still-active HelmRelease from the previous restore's values and is
created after StartedAt too; the restore then skipped its purge and
reported Succeeded on the previous restore's data.

The restore patch already sets bootstrap.newServerName to
restoredServerName(cluster, RestoreJob UID). The chart now annotates the
Cluster with it as postgres.cozystack.io/restored-server-name, whether
or not it renders the barman plugin that also carries the value, and the
purge is skipped only when the annotation names this RestoreJob. The
mark lives on the rendered Cluster rather than in RestoreJob status, so
it still covers the failed status write the skip exists for. A Cluster
rendered by a chart that predates the annotation keeps the creation-time
check.

Fixes #3322

Aleksei Sviridkin bcde187858 fix(dashboard): small Console fixes from the #3828 triage (#3837)
## What this PR does

Six small Console fixes from the #3828 triage. Each one is small and
most of the code sits in `apps/console/src`, so they go together in one
PR.

`Fixes #3105`: sizes between 1Ki and 1Mi printed as a raw byte count.
`humanizeBytes` had branches for Ti, Gi and Mi and then fell through to
bytes. It now has a Ki branch with the same `toFixed(0)` as the Mi
branch. The `1023B` case still holds, and the test covers 1Ki and 512Ki.

`Fixes #3106`: the tenant picker showed on admin pages where the tenant
changes nothing. It is now hidden on the cluster-scoped admin pages
only: Capacity, Backup classes, External IPs and Modules. The rest of
`/admin` mounts the same tenant-scoped pages as `/console`, and those
take their namespace from the tenant context, so the picker stays there.
`/admin/tenants` keeps it too, because its rows come from the
picker-filtered tenant list.

`Fixes #3107`: both capacity drill-downs showed one generic error, so a
permission failure looked like a broken page. Both now use the `error
instanceof K8sApiError && error.status === 403` check that
`ClusterStorageSection` already uses, with a test for the forbidden case
and one for a generic error on each page.

`Fixes #3102`: an immutable leaf was not restored when the YAML edit
dropped its parent object. `overlayPath` stopped as soon as the
submitted body had nothing at a path segment. It now creates `{}` for
the missing parent, but only when the target there is undefined or null
and the original really has the leaf to restore. So a scalar or an
explicit null the user put there survives. A wildcard with more path
under it does not rebuild a deleted parent, since that would put back
entries the user removed. The test uses foundationdb's
`storage.storageClass`, which is a shipped path of this shape.

`Fixes #3135`: a blocked submit did not scroll to the field that blocked
it. Plain `focusOnFirstError` crashes here, because RJSF's built-in
handler reads `form.elements` and this form is `tagName="div"`. So the
form passes a small handler that finds the field by its generated id and
scrolls it into view. The ids come from one shared definition, and the
widgets that had none now carry it: the `DynamicOptionsWidget` select,
which every `x-cozystack-options` field uses, and the `SourceField`
controls. The nested form that `AdditionalPropertiesField` mounts per
map entry continues the outer id namespace instead of restarting at
`root`, so fields like `nodeGroups.*.instanceType` resolve. A map key
with a dot in it, such as a mariadb user `john.doe`, resolves by trying
both readings of the dotted error path.

`Fixes #3108`: `cilium`, `coredns` and `verticalPodAutoscaler` have only
`valuesOverride` and no `enabled`, so they rendered as plain groups next
to the toggleable addons and looked like a switch that failed to appear.
Setting `<addon>.enabled: true` in the YAML editor is accepted, because
the schema sets no `additionalProperties`, and the API stores the field
and echoes it back. Nothing reads it. The three addons are not the same
case. `cilium` and `coredns` are always installed.
`verticalPodAutoscaler` has no switch of its own and is installed and
removed together with `addons.monitoringAgents.enabled`. The three are
now marked in `values.yaml` with a new `x-cozystack-no-enable-switch`
schema keyword, and the form renders them with a note that there is no
enable switch and an `enabled` field in YAML does nothing. The per-addon
reason goes into the schema description, which the form renders and
which regenerates into the README, the Go types and the
ApplicationDefinition.

The generated files are regenerated with cozyvalues-gen v1.7.0, the
version CI pins, and the pre-commit check passes. The console typecheck
and tests pass in CI.

### Downstream repositories

I walked the trigger map in `docs/agents/contributing.md` against the
diff, file by file. This PR changes field descriptions, adds the
`x-cozystack-no-enable-switch` schema keyword on three addon objects,
and changes the console. No field is added, removed or renamed, and no
default, version enum, `kind`, `plural`, `release.prefix`, output Secret
or Service changes, so none of the terraform provider triggers fire. No
package is added or removed, and nothing changes in
`packages/core/platform/values.yaml`, the variants, `hack/` or the node
prerequisites. cozyvalues-gen itself is unchanged, since the keyword
goes through its generic `@x-*` passthrough. The kubernetes reference
page on the website regenerates from `README.md` on a stable tag, which
is automated rather than a follow-up.

Fedor Batonogov 68cd1028bd feat(kubernetes-nodes): let CDI trust a self-hosted Talos image factory
talos.imageFactoryURL is documented for self-hosted factories and mirrors
in air-gapped, rate-limited or flaky-egress environments. Such an endpoint
is normally served with a certificate from an internal CA, and CDI — which
trusts only its system store — refuses the import with "x509: certificate
signed by unknown authority". The DataVolume never completes, no worker
joins, and the release sits in install until it times out.

DataVolume.spec.source.http.certConfigMap exists for exactly this, but the
chart rendered source.http.url alone and no value reached the field.

Add an optional talos.imageFactoryCA taking the CA in PEM form. When set,
the chart renders it into a ConfigMap in the release namespace — CDI
requires certConfigMap to sit alongside the DataVolume — and references it
from the worker DataVolume on the HTTP import path; a pool cloning a
golden image via osImage.builtin builds no source.http and renders
neither. When empty, nothing is rendered and the output is byte-for-byte
what it was.

CDI appends the bundle to the system pool rather than replacing it, so a
release pulling from a publicly-trusted endpoint keeps verifying either
way.

The value is emitted verbatim into a ConfigMap readable by anything that
can read the namespace, so the render fails closed on private key material
and on anything that is not complete PEM certificate blocks. Those guards
live in a new validate-only cozy-lib.tls.validateCACert helper that takes
the caller's field name for its messages, and cozy-lib.tls.caCertSecret is
refactored onto it, so the check exists in exactly one place.

Yasar Rahman 8580a9d46d feat(redis): size the Sentinel pods separately from Redis
Every Sentinel pod gets the Redis pods' resources, so the three
Sentinels of an instance reserve three times a Redis replica's memory
while holding only their configuration and the failover state. On a
t1.nano instance that is 3 x 128Mi while the VPA recommender's uncapped
target for a Sentinel container is 16Mi, and the waste grows with every
larger preset, because the dataset that drives the Redis sizing never
reaches a Sentinel.

sentinel.resources and sentinel.resourcesPreset follow the convention of
the top-level pair, and sentinel.resourcesPreset falls back to
resourcesPreset. Explicit Redis resources are not carried over once the
sentinel block sets either key, since they were sized for the dataset.
An empty sentinel.resources map counts as unset, as an empty top-level
resources does.

An empty sentinel block keeps today's sizing, so existing instances
render unchanged and an upgrade does not roll their Sentinels. The
Sentinel WorkloadMonitor reports the preset the Sentinels actually use.

Yasar Rahman f6f879cf38 fix(postgres)!: refuse plaintext sessions on external instances
CloudNativePG offers TLS but its built-in last pg_hba rule, host all all
all, also accepts plaintext, so a client outside the cluster that connects
with sslmode=disable gets an unencrypted session. tls.enabled only decides
whether the external hostname goes into the certificate and cannot prevent
this.

When external is true the chart now renders spec.postgresql.pg_hba with
hostssl all all all scram-sha-256 followed by host all all all reject.
CloudNativePG places user rules after its fixed rules and before its
default rule, and the first match wins, so only TLS sessions are accepted.
The pod network cannot be told apart from an external client, so in-cluster
clients are held to the same rule; libpq's default sslmode=prefer already
negotiates TLS.

The new tri-state tls.required follows external when omitted. Setting it to
false keeps accepting plaintext on an external instance and true requires
TLS on an in-cluster one.

The hostssl rule uses the same password method as CloudNativePG's own
default rule (md5 before PostgreSQL 14, scram-sha-256 from 14), so
existing md5 verifiers keep working on PostgreSQL 13. Rendering fails
when postgresql.parameters.ssl is off while TLS is required, since
hostssl would never match and every remote session would be refused.

BREAKING CHANGE: external clients that connect without TLS are refused
after the upgrade. Set tls.required to false to keep accepting them.

Aleksei Sviridkin d76bd1f263 fix(mariadb): mount the chart's my.cnf under a .cnf name
mariadb-operator up to v0.0.27 mounted the referenced ConfigMap key as
/etc/mysql/conf.d/my.cnf whatever the key was called. Since v0.0.28 the
file takes the key's own name, so the chart's key "config" became
/etc/mysql/conf.d/config, and the server's !includedir reads only *.cnf
files from that directory. Every setting in the chart's my.cnf has been
ignored since that operator bump: instances run on stock defaults,
including a 128M InnoDB buffer pool inside the 128Mi default limit.

Renaming the key restores the file as intended. Existing instances roll
their pods once, since the projected volume in the pod template changes,
and come back with the chart's settings in effect, including sql-mode
and innodb_flush_log_at_trx_commit, not only the resource sizing.

Aleksei Sviridkin 6f49e5f427 feat(openbao): optional static-key auto-unseal and apiserver egress label (#4766)
## What this PR does

This continues #4168 by @txmazing, which has been idle since 2026-09-10.
The first commit is the work from #4168 squashed into one, with
@txmazing as author. The other two commits constrain the new values and
complete the documentation.

Five changes to the managed OpenBAO app (`packages/apps/openbao`).

1. **Optional static-key auto-unseal** (#2787, #2483). `seal.type` is
`shamir`, the unchanged default, or `static`. With `static` the chart
mounts the Secret named in `seal.secretName` through the upstream
chart's `server.extraVolumes` and adds OpenBAO's `seal "static"` stanza
to the standalone and the Raft config, so the pods unseal themselves
after a restart. `seal.previousSecretName` and `seal.previousKeyId`
carry the n-1 key during a rotation. The chart never generates the key.
A cluster administrator creates the Secret in the tenant namespace,
because the `cozy:tenant:*` roles grant nothing on Secrets. A way for
tenants to supply secrets by reference is proposed separately in
cozystack/community#82.
2. **No silent seal change.** The template reads the seal in use from
the `<release>-config` ConfigMap and refuses a different `seal.type`
unless `seal.allowMigration: true` acknowledges a migration. Going from
`static` back to `shamir` is refused, because the chart cannot render
the disabled stanza that direction needs.
3. **Apiserver egress label** (#2793). The server pods carry
`policy.cozystack.io/allow-to-apiserver: "true"`, so
`service_registration "kubernetes"` reaches the API server and HA pods
no longer hang at start.
4. **Constrained values.** The upstream chart passes the server config
through `tpl`, and its start script replaces upper case placeholders
such as `HOSTNAME` in it. A key identifier with template delimiters
would run as a template inside helm-controller, which runs as
cluster-admin, so `seal.keyId` and `seal.previousKeyId` take lowercase
alphanumerics, hyphens, dots and underscores. The Secret names become
pod volume names `userconfig-<name>`, so they take DNS labels of at most
52 characters. A previous Secret or key identifier equal to the current
one fails at render. The apps API only defaults against the schema, and
Helm enforces these patterns at install and upgrade.
5. **README.** The trade-off of `static`, the key Secret, the rotation
with the pod replacement that the `OnDelete` strategy requires, the
migration from Shamir step by step after the OpenBAO guide, and the
one-time pod replacement after an upgrade so that existing pods get the
label.

### Validation

- `helm unittest .` in `packages/apps/openbao` passes 28 of 28 with
helm-unittest 1.1.2, the version CI pins, and with 1.2.1.
- Dropping the key identifier patterns, moving the Secret name limit to
51 or 53, or removing either equality guard turns the suite red each
time.
- Rendering this chart and then the vendored `openbao` chart with a
template in `seal.keyId` now stops at the schema. Without the pattern
the same two-stage render executed it, `lookup` included.
- With default values, standalone and with `replicas: 3`, `helm
template` renders the same as `main` apart from the six-line
`extraLabels` block.
- `make generate` in the package with cozyvalues-gen v1.7.0 and at the
repository root with Go 1.27.1 leaves the tree unchanged. `make
unit-tests` passes apart from seven BATS tests that fail the same way on
a clean `main` under macOS, most of them because macOS ships no
`timeout`. In `make test-controllers` only `internal/backupcontroller`
fails, because its tests do not build on current `main` either, which
#4768 fixes. `hack/check-commit-trailers.sh` passes and `cmd/api-gate`
reports no sizeable API change.
- Nothing here was run on a cluster. #4168 reports a Cozystack v1.6.3
cluster where a `replicas: 1` instance with `seal.type: static` came
back `Sealed false` after `kubectl delete pod`.

TLS between pods and an init or bootstrap job are not covered. Both are
on the #2787 list and independent of this change.

### Screenshots

No dashboard code change. The application form gains the `seal` group
from the regenerated `openAPISchema` and `keysOrder`.

### Downstream repositories

Walked the trigger map against the diff. The new `seal` field in
`packages/apps/openbao/values.schema.json` reaches the hand-written
`cozystack_openbao` resource of the Terraform provider. That is tracked
in cozystack/terraform-provider-cozystack#44, which also needs
`allowMigration` and the value constraints. The website reference page
is generated from this `README.md` for the apps listed in its
`Makefile`, and `openbao` is in `APPS`, so the page follows the next
stable tag without a follow-up. The website pages that mention the
apiserver label describe it in general terms and carry no OpenBAO
workaround. There is no `hack/` change, no platform values change, no
variant and no change to ApplicationDefinition semantics.

### Release note

```release-note
feat(openbao): the OpenBAO app can auto-unseal with OpenBAO's static-key seal (`seal.type: static`) from a Secret that a cluster administrator creates in the tenant namespace, with n-1 rotation through `seal.previousSecretName` and `seal.previousKeyId`. Shamir stays the default, and changing the seal of an existing instance needs `seal.allowMigration`. Server pods now carry `policy.cozystack.io/allow-to-apiserver: "true"`, so HA instances no longer hang at start behind the apiserver egress policy.
```

## Summary by CodeRabbit

* **New Features**
* OpenBAO supports static sealing with keys stored in an existing
Secret; Shamir sealing remains the default.
* Configure current and previous keys to support key rotation in
standalone and high-availability deployments. Keep the previous key
until stored keys have been re-wrapped.
* Seal-type changes are validated. Shamir-to-static migration requires
explicit acknowledgement; static-to-Shamir migration is not supported.
* Static-seal settings validate required key details and Secret names.
Server pods receive a label needed by the configured API-server egress
policy.
* **Documentation**
* Added guidance for configuring static sealing, managing Secrets,
rotating keys, and migrating seal types.

Aleksei Sviridkin 3dc0d046b3 fix(postgres): cap the default shared_buffers at a quarter of the memory limit (#4724)
## What this PR does

The chart renders no `shared_buffers`, and CloudNativePG does not set
one either (its default parameters in `pkg/postgres/configuration.go` at
v1.30.0, the operator version this repo ships, have no such key).
PostgreSQL therefore starts with its built-in 128MB whatever the
container gets. A full buffer pool is the whole memory limit on
`t1.nano` and half of it on `t1.micro`, which is the chart's default
preset. The pool is shared memory that the kernel cannot reclaim without
swap. A small or idle database never fills it, but a dump, index scans
over a large table or a replica catching up after a failover can, and
then the instance is OOMKilled.

Observed on a cluster running Cozystack 1.4.3, whose chart renders the
same parameters, with a three-instance `t1.nano` database. A
`pg_dumpall` run through `kubectl exec` inside the primary's container
got that container OOMKilled. The dump client ran in the same container
and shared its limit, so that first kill is weak evidence on its own.
After the failover the old primaries could not rejoin. Their `pg_rewind`
against the new 128Mi primary kept failing with `could not fetch file
list: SSL SYSCALL error: EOF detected` until that primary's memory limit
was raised to 512Mi, and then both rewinds completed.

Below a 512Mi memory limit the chart defaults `shared_buffers` to a
quarter of the limit with a 16MB floor, capped at the rendered memory
request rounded down to whole MiB. CloudNativePG rejects a Cluster when
`shared_buffers` exceeds that request, which can happen with memory
overcommit. That is 32MB on `t1.nano` and 64MB on `t1.micro`. From 512Mi
up a quarter is at least 128MB, so nothing is rendered and those
clusters keep the PostgreSQL default exactly as before. An explicit
`shared_buffers` in `postgresql.parameters` still wins at any size. The
limit is read through `cozy-lib.resources.defaultingSanitize`, the
helper that fills `spec.resources`, which is also how
`packages/apps/mariadb/templates/_tuning.tpl` sizes the InnoDB buffer
pool. Presets and partial `resources` overrides therefore resolve
exactly as they do for the container.

A quarter is the starting point the PostgreSQL documentation gives for a
dedicated server with 1GB or more, and it advises a smaller share below
1GB, so this is a ceiling for small instances rather than tuning. Larger
presets are left alone on purpose. Deriving a bigger pool for them is a
tuning change that would restart every PostgreSQL instance on upgrade,
and it does not belong in a fix.

### Upgrade impact

`shared_buffers` needs a restart. On upgrade every cluster whose memory
limit is below 512Mi and that does not set `shared_buffers` gets the new
value, and that includes every cluster created with the default preset.
The chart leaves `primaryUpdateStrategy` and `primaryUpdateMethod` at
their CloudNativePG defaults, `unsupervised` and `restart`, so the
operator restarts the replicas first and then the primary in place, and
writes pause for the length of one PostgreSQL restart. A single-instance
cluster is unavailable for that time. Clusters from 512Mi up render the
same manifest as before and are not touched.

### Validation

- `helm unittest` passes all 166 tests in 21 suites. The new suite
covers the default preset, `t1.nano`, a `resources` override that sets
only cpu, a 500Mi limit just under the threshold, the 16MB floor,
`t1.small` and `t1.large` rendering no key, an explicit value on a small
and on a large preset, and the other default parameters. Seven
additional cases cover memory overcommit, rounding down a fractional MiB
request, a request below the 16MB floor, explicit values and the
unchanged 512Mi threshold. Four cases fail against the previous PR
template.
- Breaking the threshold comparison, the 16MB floor or the divisor, or
dropping the new block, turns at least one case of the suite red each
time.
- `helm template` of the whole chart renders `t1.small` exactly as the
base does, and the default preset differs only by `shared_buffers:
"64MB"`.
- `make generate` with cozyvalues-gen v1.7.0, the version CI pins,
leaves `README.md`, `values.schema.json`, the Go types and the
ApplicationDefinition unchanged, because `values.yaml` only gains a
comment.
- The new default was not exercised on a live cluster.

### Screenshots

Not a UI change.

### Downstream repositories

Walked the trigger map in `docs/agents/contributing.md` against the
diff. It touches one chart template, a comment in `values.yaml` and a
new test file. No package is added, renamed or removed, no field in
`values.schema.json` is added, removed or renamed, and no default in
`values.yaml` changes, so the Terraform provider has nothing to restate
and the generated README is identical. Neither the website nor the
provider mentions `shared_buffers`. No entry matches.

Yan Bondarenko 4b606036bb fix(mongodb): set the s3 bucket and prefix on the bootstrap restore
With bootstrap.enabled the chart rendered a PerconaServerMongoDBRestore
without backupSource.s3.bucket. The operator CRD requires that field, so
the API server rejected the restore and the HelmRelease failed. The prefix
was missing too, and it matters just as much. For a backupSource restore
the operator builds the PBM storage from backupSource.s3 alone and takes
only the backup name from backupSource.destination, so a restore without
the prefix would look for the backup at the bucket root.

The restore now takes the bucket and prefix from the same helpers that
fill the backup storage, so it reads from where the backups are written.
Both places quote the two values, so a numeric bucket or prefix stays a
string instead of making the resource invalid. The backup storage still
leaves out an empty prefix, so running releases keep the same object. A
destinationPath that names no bucket fails at render time instead of
reaching the operator with an empty bucket.

Yan Bondarenko 3ea7a95108 docs(openbao): document the static seal trade-off and the Shamir migration
With the static seal the key sits in a Secret in the same cluster as the
data it unwraps, so the barrier is only as strong as access to Secrets
in that namespace, to etcd and to backups. The README now says so before
the reader picks a seal, and it says what the key identifier is for,
since OpenBAO picks the key for stored data by it.

Tenant roles grant nothing on Secrets and no pods/log, so a cluster
administrator creates the key Secret and reads the log line that
confirms a re-wrap.

The StatefulSet uses the OnDelete strategy, so neither a seal migration
nor the apiserver egress label reaches a running pod until it is
replaced. The README describes the migration from Shamir step by step,
following the OpenBAO seal migration guide, and says that pods created
before the label have to be replaced once.

The migration starts with a backup. The standalone file backend is not
transactional, so its volume is copied with the server stopped or
snapshotted atomically. The upgrade that sets allowMigration is the
point of no return for the chart, and the README says how a cluster
administrator backs out of it before any pod is replaced.

Yan Bondarenko bfbb5ac75f fix(openbao): constrain the seal values that reach the server config
The upstream chart passes the server config through tpl, and its start
script replaces upper case placeholders such as HOSTNAME anywhere in the
copied file. A key identifier with template delimiters would run as a
template inside helm-controller, which runs as cluster-admin, and an
upper case one could come out different on every pod. Both key
identifiers now take lowercase alphanumerics, hyphens, dots and
underscores.

The Secret names become pod volume names of the form userconfig-<name>,
which Kubernetes validates as DNS labels. Both name fields now take a
DNS label of at most 52 characters, and the volume entries are quoted.
The apps API only defaults against the generated schema, so Helm
enforces these patterns when it installs or upgrades the release.

A previous Secret equal to the current one mounts the same volume twice,
which the API server rejects for the StatefulSet, and OpenBAO refuses to
start when equal key identifiers name different key material. Both
cases now fail at render. The deepcopy functions for the Seal type are
regenerated as well.

txmazing 0c52dedbe2 feat(openbao): optional static-key auto-unseal and apiserver egress label
The OpenBAO app has no auto-unseal (#2787). Every restart of a server,
after a node drain, an image bump or an OOM kill, leaves it sealed until
an operator enters the Shamir key shares into each replica. In HA mode
the pods also hang at start (#2793). Cozystack's allow-to-apiserver
policy only admits egress from pods labelled
policy.cozystack.io/allow-to-apiserver, the app never set that label,
and service_registration "kubernetes" cannot reach the API server
without it.

A new seal value selects shamir, which stays the default, or OpenBAO's
seal "static". With static the chart renders the static seal stanza into
the standalone and the Raft config and mounts the key Secret named in
seal.secretName through the upstream chart's server.extraVolumes. The
chart never generates, stores or rotates the key, because a missed
lookup would replace it and leave the data unreadable.
seal.previousSecretName and seal.previousKeyId carry the n-1 key that
the static seal accepts during a rotation. The server pods always carry
the apiserver egress label.

Changing the seal of an initialized instance is a seal migration that
OpenBAO performs under bao operator unseal -migrate. The chart reads the
seal in use from the config ConfigMap the previous release rendered and
refuses a different seal.type unless seal.allowMigration acknowledges
the migration. Moving away from static needs the old stanza kept with
disabled = "true", which the chart does not render, so that direction is
refused regardless. The README documents the key Secret, the rotation
with the pod replacement that the OnDelete update strategy requires, and
the log line that confirms the re-wrap.

Yan Bondarenko 6dbd76ae50 fix(postgres): cap the default shared_buffers at a quarter of the memory limit
The chart renders no shared_buffers, so PostgreSQL starts with its 128MB
default whatever the container gets. A full pool is the whole memory
limit on t1.nano and half of it on t1.micro, the default preset. The
pool is shared memory that the kernel cannot reclaim without swap, so
when a dump, index scans over a large table or a replica catching up
after a failover fill it, the instance is OOMKilled.

Instances below a 512Mi memory limit now default to a quarter of the
limit, at least 16MB. From 512Mi up a quarter is at least 128MB, so
those instances render exactly as before. shared_buffers needs a
restart, so on upgrade CloudNativePG restarts every instance below
512Mi that does not set it explicitly.

Aleksei Sviridkin 6addef4d3c fix(kubevirt): route the export proxy to the Service KubeVirt creates (#4637)
## What this PR does

The VM export routes point at a Service that does not exist, and the
tenant network policy would block the Ingress even if it did.

KubeVirt creates the export proxy Service under the name
`virt-exportproxy` (`VirtExportProxyName` in
`pkg/virt-operator/resource/generate/components`, v1.9.0). The Ingress
and the TLSRoute that publish `vm-exportproxy.<host>` name a
`vm-exportproxy` Service, and nothing creates one. The backend was
`virt-exportproxy` when the Ingress was added in 0ddaff938. Then
3780925a6 renamed the hostname to `vm-exportproxy` and the backend along
with it. The hostname stays, only the backend goes back.

Renaming the backend is not enough for the Ingress, because it is served
by the ingress controller in tenant-root and tenant egress is
default-deny. Each allowed destination has its own `allow-to-*` policy.
The CDI upload proxy has `allow-to-cdi-upload-proxy`, the export proxy
had nothing. The new `allow-to-vm-exportproxy` policy renders for the
same tenants and the same source pods as the CDI one. Its destination is
narrower: only the `kubevirt.io=virt-exportproxy` pods in
`cozy-kubevirt`, on TCP 8443, the container port virt-operator gives
them.

The unit tests pin the backend name for the Ingress and the TLSRoute,
and the placement, selector and port of the new policy.

I checked this on a test cluster with KubeVirt v1.9.0 and ingress-nginx.
Without the fix the controller logs `Error obtaining Endpoints for
Service "cozy-kubevirt/vm-exportproxy"`. With the backend renamed and
the tenant allowed egress to virt-exportproxy, a passthrough request to
`vm-exportproxy.<host>` reaches the export proxy, and it answers with
its own serving certificate.

## What this PR does

Redis and postgres server certificates now carry the per-engine external
name `<release>.<engine>.<apex>` (for example
`redis-foo.redis.example.org`) next to the flat `<release>.<apex>` they
already had. Both names appear under the same condition as before: TLS
on and `external: true`, with a tenant apex present.

A TLS-passthrough listener on the tenant Gateway forwards the handshake
untouched, so the certificate the client checks is the engine's own. The
design in #2815 routes databases by SNI under `*.redis.<apex>` and
`*.postgres.<apex>`, and without the per-engine name in the SAN list a
verifying client would fail the hostname check. Issuing both names now
means a later move between the two hostname schemes reissues no
certificate and keeps clients on the same trust anchor. This is the
certificate step of #2815. Nothing renders a route yet.

The SAN list changes, so an existing external TLS release gets its
server certificate reissued once on upgrade, from the same CA. For redis
the operator then rolls the Redis and Sentinel pods one at a time, the
same way it handles a renewal.

The READMEs say who can reach the new name through a passthrough
listener. For postgres that is only clients using direct TLS negotiation
(server 17+, `sslnegotiation=direct`), because by default a plaintext
SSLRequest comes before the handshake. `redis-cli` needs `--sni`.

MongoDB is not in this PR. PSMDB issues the certificate itself and its
CRD has no field for extra SANs, so adding the mongos name means the
chart taking over the certificate. That needs its own change.

Covered by helm-unittest: the name is present with TLS and external on,
and absent with external off, with TLS off, and in a tenant with no
apex.

## Summary by CodeRabbit

* **New Features**
* PostgreSQL TLS certificates now cover both the tenant hostname and the
per-engine `postgres` hostname for external connections.
* Redis TLS certificates now also cover the per-engine `redis` hostname
when external services are enabled.

* **Documentation**
* Clarified connection requirements for per-engine hostnames: PostgreSQL
routing requires direct TLS negotiation, PostgreSQL 17 or later, and a
compatible client; Redis clients must specify SNI.
* Clarified that the hostnames may need to be mapped manually to the
LoadBalancer address.

Aleksei Sviridkin 5486d4ffcf fix(networking): harden webhook policy assumptions (#4058)
## What this PR does

This is follow-up for
[#3997](https://github.com/cozystack/cozystack/pull/3997). It reads
ingress-nginx admission port from effective subchart values and refuses
empty value, and fixes `kubeProxyReplacement=false` status because
cozystack has no supported Service translator in that state. Gateway
test now requires one real ClusterIP and keeps same ready Pod UID, IP
and port for whole probe, so stale EndpointSlice, replaced Pod or wrong
Service can't report deny. Policy selectors and two-ended deny from
[#3997](https://github.com/cozystack/cozystack/pull/3997) stay
unchanged, and this does not claim root cause for
[#3983](https://github.com/cozystack/cozystack/issues/3983).

## Summary by CodeRabbit

- **Bug Fixes**
- Admission webhook connectivity checks now validate the configured
Service and its exact backend endpoint throughout probing, improving
failure detection.
- Admission webhook policies now fail closed when the webhook port is
not explicitly configured.

- **Documentation**
- Clarified that supported service routing requires
`kubeProxyReplacement: true`.
- Updated guidance to explain that disabling this setting or webhook
policies does not provide a supported fallback.

- **Tests**
- Added coverage for missing webhook port configuration and strengthened
networking stability checks.

## What this PR does

I remove internal cluster names, a real hostname with its IP addresses,
internal mirror hostnames and an internal product name from comments, an
example file, test fixtures and a dead commented-out config block. Where
a stand-in is needed I use neutral test-cluster wording, RFC 2606
domains or RFC 5737 documentation addresses. I also replace two real
Keycloak usernames and a reviewer's name in code comments with
placeholders, or drop them. Rendered output does not change. The test
fixture hostnames change on the input and the expected side together,
and the unit tests of every touched package still pass.

Aleksei Sviridkin bc9a594e47 test(clickhouse): add backup API render assertions (#4011)
## What this PR does

This adds unit tests for how the ClickHouse chart wires up the backup
API that the default backup strategy calls. The Pod of the
`cozy-default-altinity` strategy reaches the clickhouse-backup sidecar
on the named port `ch-backup-api`. It authenticates with the credentials
from the `<release>-backup-api-auth` Secret.

The new suite is
`packages/apps/clickhouse/tests/backup_api_contract_test.yaml`. It
checks that:

- the sidecar exposes `ch-backup-api` on 7171/TCP;
- `API_USERNAME` and `API_PASSWORD` come from the `username` and
`password` keys of `<release>-backup-api-auth`;
- that Secret renders with `username: backup` and a non-empty password;
- no auth Secret renders when backups are disabled.

All of this is rendered by the chart, so the unit tests catch a
regression on every pull request. The e2e assertions on the same wiring
run only when test-impact analysis selects the ClickHouse suite. They
stay as they are in `hack/e2e-chainsaw/clickhouse`, because they check
the operator-created Pod and the admitted Secret, and rendering can't do
that.

Aleksei Sviridkin a1416655f4 fix(tenant): allow tenant egress to the KubeVirt export proxy
The vm-exportproxy Ingress is served by the ingress controller in
tenant-root, and tenant egress is default-deny. Nothing allowed traffic
to virt-exportproxy in cozy-kubevirt, so the Ingress stayed unreachable
even with the right backend Service. The new policy renders wherever
allow-to-cdi-upload-proxy does, but narrows the destination to the
export proxy pods and their container port.

Myasnikov Daniil 35abe2dcbd fix(dashboard, kubernetes): say which cluster addons have no enable switch
cilium, coredns and verticalPodAutoscaler carry only valuesOverride and
no enabled, and the addon template keys its toggle off the presence of
enabled, so all three rendered as plain groups among the toggleable
addons, reading as a switch that failed to appear. That is what leads
users to add <addon>.enabled: true in the YAML editor, where the schema
sets no additionalProperties, so the API stores the field and echoes it
back while nothing reads it.

The three are not the same case, so the form must not claim they are.
cilium and coredns are always installed. verticalPodAutoscaler has no
switch of its own but is installed and removed together with
addons.monitoringAgents.enabled, so calling it mandatory would be
wrong. The fixed copy states only what holds for all three, that there
is no enable switch and that an enabled field in YAML does nothing, and
the per-addon reason moves into the schema description, which the form
already renders and which regenerates into the README, the Go types and
the ApplicationDefinition.

Also types the test fixture instead of spreading it as object, which
erased the props and left the file failing tsc.

Aleksei Sviridkin 48e3d1d611 feat(redis,postgres): certify the per-engine external hostname
The tenant Gateway's TLS-passthrough listeners are designed to route
databases by SNI under a per-engine subdomain (*.redis.<apex>,
*.postgres.<apex>), and a passthrough listener forwards the handshake
untouched, so the engine's own server certificate must carry
<release>.<engine>.<apex> or a verifying client fails the hostname
check.

The name is issued next to the existing flat <release>.<apex>, under
the same TLS-and-external condition, so that a later move between the
two hostname schemes reissues no certificate and leaves clients on the
same trust anchor. Nothing renders a route yet; the certificate is
prepared ahead of it. Adding the name changes the SAN list, so existing
external TLS releases get their server certificate reissued once on
upgrade, from the same CA.

Aleksei Sviridkin 92bf90cc7d fix(kubernetes): force the kubevirt-csi temp NFS unmount after a timeout
The NFS publish path temp-mounts the export root and unmounts it in a
defer with a plain umount, which has no deadline. If the NFS server is
gone by then, that umount can block indefinitely: the publish hangs and
the temp mount stays behind for the life of the node plugin container.

mount-utils' UnmountWithForce cannot fix this. It retries with -f only
after its first umount returns, and that umount forks the umount.nfs
helper: killed on the timeout, umount leaves the helper stuck on the
vanished server with the output pipe still open, and CombinedOutput
waits for the pipe, so -f never runs. The plugin therefore runs umount
itself with WaitDelay set, which closes the pipe shortly after the
kill, and falls back to umount -f under a timeout of its own. As in
mount-utils, "not mounted" counts as done: umount2 detaches the mount
before it blocks tearing the superblock down, so the -f after a killed
umount can find nothing left. A mounter that is not the exec-based one
keeps its plain Unmount.

An umount in uninterruptible sleep outlives any kill, so the cleanup
also waits at most one fixed budget, well inside the 2m deadline
kubelet puts on NodePublishVolume, and leaves a stalled unmount
running in the background, where it logs its result once it ends. The
temp dir is removed by that background unmount once it succeeds, not
by the publish: removed at the deadline it is still a mount point, and
nothing would retry.

A forced unmount runs nfs_umount_begin, which kills every RPC in
flight on the superblock, and NFS shares one superblock between mounts
of the same export with the same options. The temp mount therefore
gets nosharecache, so -f cannot fail the I/O of pods on the node that
mount the same volume.

Aleksei Sviridkin d2e3eb4f82 fix(kubernetes, e2e): unblock autoscaling below min size, size the computeplane pool, fix the backupcontroller build (#4768)
## What this PR does

Makes the backupcontroller test package compile again on main. #4587
added a flavor argument to `createCNPGBackupArtifact` and
`marshalCNPGBackupSnapshot`, and #4669, whose CI ran before that, added
two test calls with the old argument lists. Both PRs were green on their
own, and together they break `go test ./internal/backupcontroller/`. The
two calls now pass the same default flavor as the other tests in the
file.

The second commit fixes an e2e suite that fails the required E2E check
here. It is the `computeplane` suite from #4713, and its worker pool was
one node with a single vCPU. After the kubelet reservations that node
has 900m of CPU to allocate. The tenant addons (cilium, coredns, csi,
ingress-nginx, metrics-server, cert-manager) request exactly 900m
between them. If cert-manager's startupapicheck hook pod is created
last, it can't be scheduled and the install times out after 10m. The
reinstall after remediation runs into the same full node. Whether that
pod comes last depends on install order, so the suite passed on #4713
and failed here.

The pool now has two workers with one vCPU each, the same shape the
kubernetes suites use. One vCPU per worker stays on purpose, because of
#3513.

Two workers exposed a deadlock in the tenant cluster-autoscaler. The
suite's pool is created at zero replicas and then gets a min size of 2,
which CAPI does not apply to the live replica count on upgrade (#4786).
The autoscaler's scale-up for a pending pod asks for one node, and the
clusterapi provider refuses it because one is under the min size,
although it is an increase. That refusal backs the group off, and the
min-size enforcement skips groups in backoff, so the pool never leaves
zero. Upstream had the same report in kubernetes/autoscaler#4942, closed
as stale, and it is now tracked in kubernetes/autoscaler#10400. Our
autoscaler image already patches the mirror case for max size, and the
patch now refuses only a decrease below the min size.

`go vet` and `go test ./internal/backupcontroller/...` pass, and so do
the bats pins for the computeplane suite. The autoscaler patch adds a
test for each direction, and the clusterapi package tests pass with it
applied to 1.32.0.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved cluster autoscaling for worker groups outside configured size
limits: groups below their minimum can scale up toward it, and nodes can
be removed when a group exceeds its maximum. Scale-down requests below
the minimum remain restricted.
* **Tests**
* Updated backup and restore test calls with PostgreSQL and empty flavor
values.
* Updated ComputePlane checks for a two-worker pool and clarified
cert-manager installation timing expectations.

Aleksei Sviridkin 82ae9f6cf7 fix(kubernetes): let the autoscaler grow a node group that sits below min
The clusterapi provider refuses any SetSize under the group's min size,
including an increase. A pool whose min size is raised while it stands
at fewer replicas then deadlocks: the scale-up for pending pods asks for
fewer nodes than the min, is refused, and puts the group in backoff,
and the min-size enforcement skips groups in backoff. The group stays
where it is for good.

Refuse only a decrease below min size. The guard it keeps is the one
DecreaseTargetSize relies on, and DeleteNodes checks min size itself.

Aleksei Sviridkin 9620be0103 feat(postgres): add per-user createRole and bypassRls attributes (#3505)
## What this PR does

- Adds `users.<name>.createRole` to the postgres chart, which sets the
`CREATEROLE` role attribute on a managed login user.
- Adds `users.<name>.bypassRls`, which sets `BYPASSRLS` on the same
user. The two attributes are needed together to provision a privileged
service role, see below.
- Sets `createrole_self_grant` as a role-level default alongside
`createRole`, without which the attribute is granted but not usable.
- Refuses `createRole` on PostgreSQL 15 and older, where it is an
escalation path rather than a bounded privilege.
- Makes the init job record the roles it manages in a superuser-only
marker instead of trusting role comments and refuses to adopt a role it
did not create once `createRole` has been used, see below.
- Adds `tests/user_createrole_test.yaml`: defaults, both explicit values
for each attribute, composition with `replication` and with each other,
the `createrole_self_grant` set and reset paths, and the version guard
on v15 and v13. Adds `tests/managed_roles_test.yaml` for the marker and
the adoption checks.

Today a tenant that needs to create its own roles has no way to do it
through the chart, because role attributes are not inherited through
role membership: granting `CREATEROLE` to the generated `<db>_admin`
group role has no effect on the users that are members of it, and
`<db>_admin` is `NOINHERIT` anyway. The attribute has to be set on the
login user itself, which only the init script can do. The remaining
option is to hand the tenant the `postgres` superuser, which also gives
it `COPY ... FROM PROGRAM`, arbitrary file access and command execution
inside the instance pod. These flags are the narrow version of that: the
tenant manages its own roles, and the superuser stays internal.

Both attributes are reconciled on every init-script run, like
`replication`, so setting one back to `false` emits the `NO...` form and
revokes it.

## Why `bypassRls` belongs in the same PR

`CREATEROLE` on its own does not let a tenant reproduce a role layout
that uses row-level security, which is the common case this feature
exists for. PostgreSQL only lets a role create other roles carrying
`BYPASSRLS` if it holds the attribute itself, so `CREATE ROLE
service_role ... BYPASSRLS` fails with `Only roles with the BYPASSRLS
attribute may create roles with the BYPASSRLS attribute`. Exposing
`createRole` without `bypassRls` therefore ships a feature that stops
one statement short of the goal.

`bypassRls` is not gated on a PostgreSQL version, because it carries no
escalation of its own: `BYPASSRLS` waives row-level security inside the
tenant's own databases, and the database owner already reads every row
in them. It grants no reach outside the tenant's data.

## Why `createrole_self_grant` is set with the attribute

This is the non-obvious half. PostgreSQL 16 grants a `CREATEROLE` holder
only `ADMIN OPTION` on the roles it creates, governed by
`createrole_self_grant`, whose default is empty. `ADMIN OPTION` allows
granting the role onward but not `SET ROLE` to it, and creating an
object owned by another role requires `SET`. The attribute therefore
looks functional -- `CREATE ROLE` succeeds -- while the very next
statement a tenant writes, `CREATE SCHEMA ... AUTHORIZATION <new role>`,
fails with `must be able to SET ROLE`. Every tenant granted `createRole`
would hit this and have to discover the parameter, so the chart sets it
as a role-level default and resets it when the attribute is withdrawn.

## Why the init job stops trusting role comments and role names

The init job runs as the superuser, and it trusted two things a
CREATEROLE holder controls for the roles it creates. It picked the users
and roles to drop by their comment, and on PostgreSQL 16 a CREATEROLE
holder may `COMMENT ON ROLE` every role it created, so it could hand the
chart for deletion a role the chart never created. It also adopted any
role that already existed under a declared name, so a role created under
a name an administrator declares later stayed under its creator's
control, for example `debezium` before `users.debezium.replication:
true`, or `newdb_admin` before `databases.newdb`.

Neither case can be caught from the catalog. Creating a role through an
intermediate role and then dropping that role leaves the squatted role
with no row in `pg_auth_members` at all, while the objects, role
settings and default privileges planted in it stay. On 17.11 such a
`debezium` had zero memberships, and after the chart adopted it
`migrator` could still run code as `debezium` with `REPLICATION` through
a function it had planted. The chart therefore keeps its own record:

- Chart-managed roles are members of `cozystack:managed`, a NOLOGIN role
that only the superuser can grant. On 16+ the membership is `WITH
INHERIT FALSE, SET FALSE`. The name is outside the username and database
charsets. The delete passes act only on these members. On its first run
the chart marks every role it had commented before, when no role could
yet hold CREATEROLE through it.
- Once any user has held `createRole`, recorded as
`cozystack.createrole_granted` on the `postgres` database (the same
mechanism as `cozystack.adopted_restore`), the chart refuses to adopt an
existing role it did not mark, both for users and for
`<db>_admin`/`<db>_readonly`. The init job fails with the role's name,
and a platform administrator must drop the role. Before that point
adoption works as before, so a fresh install that declares `users.app`
still adopts the role CNPG bootstraps.

## The PostgreSQL 16 floor on `createRole`

The floor is a security boundary, not a cosmetic check. Before
PostgreSQL 16, `CREATEROLE` allowed granting membership in any
non-superuser role, so a user holding it could grant itself
`pg_execute_server_program` and reach command execution on the instance,
which is exactly what not exposing the superuser is meant to prevent. I
verified both sides on a real cluster: on 15.15 `GRANT
pg_execute_server_program TO <createrole_user>` succeeds and `COPY ...
FROM PROGRAM 'id'` then returns `uid=26(postgres)`; on 16.11 and 18.1
the same grant is refused because it now requires ADMIN option on the
role. PostgreSQL 16 restricted `CREATEROLE` to roles the grantee
administers, which is what makes the attribute safe to expose. The guard
uses the same fail-fast `SECURITY:` idiom as the blocked
`postgresql.parameters` list in `templates/db.yaml`.

Note that a grant obtained on PostgreSQL 15 survives a major upgrade:
after moving an instance to 16.11 the user kept its membership in
`pg_execute_server_program` even though new attempts were refused.
Operators who exposed `CREATEROLE` out of band on an older major should
audit and revoke memberships in `pg_execute_server_program`,
`pg_read_server_files` and `pg_write_server_files` before relying on the
floor.

## Verification

The marker, adoption and `createRole` paths were rendered and run
against live PostgreSQL 13, 15, 16 and 17 containers. An upgrade from
the previous chart marks the roles it already managed and removes a
dropped user. What happens to a dropped role's objects comes from #4574
and is covered by its tests. A fresh install adopts the CNPG `app` role
in the same run that grants `createRole`. A forged comment is ignored,
and squatted `debezium` and `newdb_admin` roles stop the init job with
nothing granted to them. The orphaned-role pass still drops the roles of
a removed database, and every re-run is clean. Reverting each part of
the fix in turn fails `tests/managed_roles_test.yaml`.

Beyond the chart unit tests, I replayed a real migration checklist
against a live PostgreSQL 17.7 instance, connected as the managed login
user and never as the superuser: creation of four roles with their
attributes including `CREATEROLE` and `BYPASSRLS`, `CREATE SCHEMA ...
AUTHORIZATION` landing on the requested owner, trusted extensions into a
named schema, per-role and per-database `search_path`, per-role
`statement_timeout` and `idle_in_transaction_session_timeout`, RLS
including `FORCE ROW LEVEL SECURITY` verified end to end (a plain role
sees zero rows, the `BYPASSRLS` role sees them all), and `SECURITY
DEFINER` functions. All of it succeeds without the superuser. The one
thing that remains out of reach is `CREATE EVENT TRIGGER`, which
PostgreSQL restricts to superusers and no chart flag can change.

Other attributes and the predefined roles that a managed-service admin
role usually wants (`pg_monitor`, `pg_read_all_settings`, `pg_maintain`)
can follow the same per-user pattern in a later PR, minus the three that
grant OS access (`pg_execute_server_program`, `pg_read_server_files`,
`pg_write_server_files`).

### Screenshots

No UI change.

### Downstream repositories

`packages/apps/postgres/values.schema.json` gains two fields, which per
the trigger map reaches `cozystack/terraform-provider-cozystack`: its
postgres resource carries a hand-maintained schema plus an
expand/flatten pair for `users`, with no codegen from
`values.schema.json`, so `createRole` and `bypassRls` will be invisible
to Terraform users until they are added there by hand. I searched that
repository and found no open PR or issue covering it (the only open PR
is a dependabot Go module bump). I have not filed the follow-up, so I am
leaving the box unticked rather than claiming work that does not exist.
Happy to open the issue or the provider PR if a maintainer confirms that
is the preferred route.

I walked the rest of the map against the diff and found nothing else: no
package is added, renamed or removed, no version enum changes, no
default changes, `release.prefix` and the output Secret and Service
names are untouched, and no CRD outside the regenerated
`packages/system/postgres-rd/cozyrds/postgres.yaml` is affected. The
`README.md` parameter table is regenerated here and postgres is already
in the website generator's app list, so the website path stays
automated.

### Release note

```release-note
feat(postgres): add `users.<name>.createRole` and `users.<name>.bypassRls`, which grant the CREATEROLE and BYPASSRLS attributes to a managed user so a tenant can create and manage its own roles, including roles that bypass row-level security, without the postgres superuser. `createRole` also sets `createrole_self_grant` on the user so that roles it creates can own objects. `createRole` requires PostgreSQL 16 or newer: on older majors CREATEROLE can be used to grant oneself pg_execute_server_program and reach command execution on the instance, so the chart refuses to render the attribute there. The init job now records the roles it manages as members of a superuser-only `cozystack:managed` role instead of trusting role comments. Once `createRole` has been used on an instance, it refuses to adopt an existing role it did not create.
```

## What this PR does

A guest whose interfaces are rendered by netplan ignores two things the
platform already puts on the wire for it, and this adds an opt-in
`netplanDhcp` value that supplies the cloud-init network-data making it
ask for both.

`virt-launcher` starts a DHCP server on **every** bridge-bound
interface, secondary ones included — `newDHCPConfigurator` in
`pkg/network/setup/launcher/configurator.go` gates only on `iface.Bridge
!= nil`, and `BridgeConfigGenerator.Generate` serves the address the CNI
put on the pod-side interface along with that link's MTU. The chart
renders `bridge: {}` for every network, so a VM joined to a VPC subnet
is offered its reserved address and its MTU. cloud-init's fallback
network configuration covers a single interface, so on Debian and Ubuntu
nothing ever sends a DHCPDISCOVER on the second NIC and the interface
stays inert, while AlmaLinux (NetworkManager auto-profile) and Windows
come up. That asymmetry is the tell: with no DHCP server at all, none of
the three would work.

The same DHCP server advertises the launcher pod's search domains as
option 119, and `UseDomains=` defaults to `no` in systemd-networkd, so a
netplan-managed link keeps none of them. A cluster domain under `.local`
then reaches the mDNS exclusion in resolved and every lookup answers
`REFUSED`, which is #2085. `dhcp4-overrides: use-domains: true` is
enough on its own: the domains on the wire already carry whatever
cluster domain the cluster actually uses, so nothing needs to be
hardcoded here and #2372 does not collide with this.

### This is a regression, not a missing feature

`packages/apps/virtual-machine` carried exactly this, added in c63fb203b
(*[apps] virtual-machine: add vpc support*, 2025-10-21) as
`templates/secret-network-config.yaml` plus a `networkDataSecretRef`,
gated on `.Values.systemDisk.image`. 08a5f9890 (*feat(platform): remove
virtual-machine application*, 2026-02-12) deleted the application and
the template with it, and `vm-instance` never had one — `git log --all
-S networkDataSecretRef -- packages/apps/vm-instance/` is empty. The
gate could not be ported verbatim because `systemDisk.image` went away
in the same split, which is the likeliest reason nobody did. #2166 is
the other regression from that migration.

`docs/vm-external-vlan.md` has since documented the absence as a
property of the chart and prescribed a `write_files` + `netplan apply`
workaround, so this PR updates that page too.

### Why it is opt-in

The network-data renders only when `netplanDhcp` is `true`, and the
value defaults to `false`. Keying it on `instanceProfile` instead cannot
work: the profile defaults to `ubuntu` whatever image the disk holds,
and it is a KubeVirt preference rather than a declaration of the guest's
network stack. cloud-init passes a v2 configuration through verbatim
only for the netplan renderer; sysconfig, NetworkManager and eni turn
each `match` stanza into an interface literally named `cozy-en` or
`cozy-eth`, so a non-netplan guest handed this configuration loses DHCP
on its real NIC.

Two cases where the value must stay off, both stated in its description
and in `docs/vm-external-vlan.md`:

- A guest not rendered by netplan (AlmaLinux, Rocky, Alpine), for the
reason above.
- A guest that configures a NIC statically through netplan, as the
external-VLAN recipe does. Netplan writes one networkd file per
definition ID and systemd-networkd applies only the first `.network`
file in lexical order that matches a link, so
`10-netplan-cozy-en.network` shadows `10-netplan-enp2s0.network` and the
static address is never applied, whatever number the user's netplan file
carries. Reproduced with `netplan generate` on Ubuntu 24.04.

Matching by MAC with a v1 configuration would be renderer-independent
and would not shadow a named interface, but it needs the chart to know
the MACs at render time; `lookup` cannot supply them on a first install,
so the chart would have to pin them, which is a larger change that
overlaps #4038.

### What this does not do

A VM that leaves `netplanDhcp` unset renders exactly as before: no
network-data Secret, and no cloud-init disk where there was none.
Turning the value on for a VM with neither `cloudInit` nor `sshKeys`
adds a cloud-init disk, and because KubeVirt uses the pinned firmware
UUID as the NoCloud instance-id, a guest that has never seen that id
treats its next boot as a first boot (new SSH host keys); the value's
description says so. On a VM that already has a cloud-init disk the
instance-id does not change, and it is derived from the namespace, the
name and `cloudInitSeed`, so recreating the VM keeps it too; cloud-init
applies network configuration per instance by default, so such a guest
picks the network-data up once `cloudInitSeed` is changed. Static
addressing is still `userData`.

### Tests

`tests/network_data_test.yaml`, 6 cases: the rendered network-data
asserted in full (both properties, not just the presence of the key),
the VM carrying network-data with no user-data requested, user-data and
network-data side by side, a VM on the default profile rendering neither
the Secret nor a cloud-init disk, user-data alone when the value is off,
and the value rather than the profile deciding. With the templates gated
on the `ubuntu` profile again, the default-profile case and the
value-off case go red.

`helm unittest` green on all four suites of the package (32 tests).
`make generate` output is committed (`values.schema.json`, `README.md`,
`api/apps/v1alpha1/vminstance/types.go`,
`packages/system/vm-instance-rd/`). `helm lint` fails on this package
identically on an untouched tree (`_cluster.scheduling` nil pointer,
`cozy-lib` dependency metadata), so it is not a signal here.

### Screenshots

Not a UI change.

### Downstream repositories

<!--
Cozystack is upstream for repositories that are NOT kept in sync with it
automatically, and nothing in CI compares the two sides, so a change
here can break them silently.

Which change forces what, and which file to touch, is the trigger map in
docs/agents/contributing.md under "Downstream Repositories". Walk it
before you tick anything.

IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM
TO FILL IN:

1. Walk the trigger map against the actual diff of this PR, file by
file. Do not decide from the PR title or from your memory of what you
changed.
2. For every repository you tick, open the follow-up PR there and link
it on the same line. A ticked box with no link claims work that does not
exist, which is worse than an empty box. Search that repository for an
open PR or issue covering it first, and link that instead of filing a
duplicate.
3. When the follow-up is out of scope, or needs a decision that is not
yours to make, open an issue in that repository instead, link that, and
say so in the PR body. Do not push a speculative PR into another
repository just to fill a line here.
4. Do not tick "No downstream repository is affected" to make the
checklist go away. If you are unsure, leave every box empty and say so
in the PR body, so a human decides.
-->

<!-- Trigger map walked file by file against the diff.
`docs/vm-external-vlan.md` documents the absence this PR removes, which
is the "make a documented workaround obsolete" trigger, so the website
copies of that page need the same edit and issue 702 carries it.
`netplanDhcp` is a new field in `values.schema.json`, which the provider
models by hand, and issue 62 there carries it. No package added, renamed
or removed; no hack/ or ApplicationDefinition change; the cozy-proxy
annotations in templates/service.yaml are untouched. -->

```release-note
fix(vm-instance): a new `netplanDhcp` value, off by default, makes the chart supply cloud-init network-data that requests DHCP on every ethernet interface and accepts the DNS search domains offered over DHCP. A netplan guest (Ubuntu, Debian) attached to a VPC subnet then configures that interface on its own instead of leaving it unaddressed, and cluster service names under the cluster domain resolve inside the guest. Leave it off for guests not rendered by netplan and for guests that configure a NIC statically through netplan. VMs that do not set it are unchanged.

## Summary by CodeRabbit

* **New Features**
* Added an opt-in setting to request DHCP on Ethernet interfaces in
supported virtual machines while retaining DHCP-provided DNS search
domains.
* The setting is off by default. Enabling it can add a cloud-init disk
and may interfere with static network settings or guests that do not use
netplan.

* **Documentation**
* Updated setup guidance with considerations for enabling DHCP and
configuring static networking on VLANs without a DHCP server.

Aleksei Sviridkin bcda5c893a feat(kubevirt)!: drop HotplugVolumes for declarative volume hotplug (#4453)
## What this PR does

This turns off the deprecated KubeVirt `HotplugVolumes` gate and moves
the platform to declarative volume hotplug. It changes how every volume
hotplug on the platform works, so the title carries `!`. Closes #4032.

This PR is stacked on #4451 and has to merge after it. #4451 adds the
kubevirt-csi flag this PR flips.

The replacement gate is already on in KubeVirt 1.9, and the old gate is
the only thing keeping it off. `DeclarativeHotplugVolumes` is Beta at
v1.9.0, and Beta gates are on by default. virt-controller skips
`handleDeclarativeVolumeHotplug` while `HotplugVolumes` is on, so
dropping the old gate is what switches the new one on.

The kubevirt-csi fallback goes off in the same change. With the old gate
off, virt-api rejects the VMI-level `removevolume` on a VM-owned VMI, so
the chart now passes `--enable-vmi-hotplug-fallback=false`. The comments
next to the gate and the flag point at each other.

This needs the rebuilt kubevirt-csi image. A driver built before #4451
does not know the flag and exits on it at startup. The image is stamped
at release preparation and ships in the same release as this change, so
only a `make apply` from main before then would crash-loop the CSI
controller.

What changes at runtime on an upgrade:

- The VM-level `addvolume` and `removevolume` calls now edit `VM.spec`
directly. virt-controller then makes the VMI hotplug volumes match it,
instead of going through `VM.status.volumeRequests`.
- Volumes hot-plugged through the VM subresource are in `VM.spec`, so
they stay attached.
- During a tenant teardown, when the VM goes before its VMI, the driver
no longer calls the VMI subresource. It waits for the VMI status to drop
the volume, and the garbage collector deletes the VMI with its VM.
Upstream waits up to two minutes. If the VMI is still there after that,
the unpublish fails and is retried.

A new platform migration keeps old VMI-only volumes attached. On its
first pass virt-controller removes every hotpluggable VMI volume that is
missing from `VM.spec`. Until July 2025 kubevirt-csi attached volumes at
the VMI level (the Role then granted
`virtualmachineinstances/addvolume`), and live migration carries such a
VMI across KubeVirt updates. Without help, a tenant node not recreated
since then would lose a mounted disk on upgrade.

Migration 59 copies each such volume and its disk from the VMI into the
VM template before anything else changes. Adding a hotplug volume to the
VM spec is a valid live update in KubeVirt, so no VM needs a restart. It
runs as the platform chart's pre-upgrade hook, before the upgrade
re-points `cozystack-packages`. The KubeVirt CR and the tenant
kubernetes charts both render from that source, so the gate and the flag
cannot change before the migration has finished. It only touches VMs
that need it, logs each one, and a second run changes nothing.

The migration also makes ephemeral hotplugs permanent. A volume a user
added at the VMI level, for example with `virtctl addvolume` without
`--persist` from an older virtctl, has the same shape as kubevirt-csi's
old attachments, because virt-api builds both the same way. There is
nothing reliable to tell them apart by, so both are copied. Leaving the
user's volume out would not keep it ephemeral: the first reconcile would
unplug it from the running VM. After the upgrade it is part of `VM.spec`
and attaches again on a restart, and `virtctl removevolume` drops it.

Ephemeral hotplug stops working on VMs. With the old gate off, virt-api
refuses VMI-level `addvolume` and `removevolume` on a VMI that a VM owns
(`vmiVolumePatch` in v1.9.0). A volume on such a VMI is added and
removed through the VM from then on. A VMI without a VM is not affected.

Only running VMIs are copied. virt-controller reconciles no other VMI,
and a stopped VM builds its next VMI from `VM.spec`, so copying from a
stopped one would bring back volumes the restart was going to drop.

Migrations run only on the isp-full, isp-full-generic and isp-hosted
variants. KubeVirt comes from the platform only on isp-full and
isp-full-generic, so those are covered. On the default variant, where
packages are installed by hand, nothing runs the migration.

This optional check lists the VMIs and volumes the migration would copy.
It uses the same rule. On the default variant, run it before upgrading
and recreate each tenant node it lists:

```bash
kubectl get vm,vmi --all-namespaces --output json | jq --raw-output '
  ([.items[] | select(.kind == "VirtualMachine")
    | {key: "\(.metadata.namespace)/\(.metadata.name)", value: [.spec.template.spec.volumes[]?.name]}]
    | from_entries) as $vm
  | .items[] | select(.kind == "VirtualMachineInstance")
  | ([.metadata.ownerReferences[]? | select(.controller == true and .kind == "VirtualMachine" and (.apiVersion | startswith("kubevirt.io/"))) | .name][0]) as $owner
  | "\(.metadata.namespace)/\($owner)" as $key
  | select(.status.phase == "Running" and $owner != null and $vm[$key] != null)
  | .spec.volumes[]? | select(.dataVolume.hotpluggable == true or .persistentVolumeClaim.hotpluggable == true)
  | .name as $n | select($vm[$key] | index($n) | not)
  | "\($key) \($n)"'
```

Empty output means nothing is affected. I checked the query against the
migration's test fixtures only. Neither the query nor the migration has
run on a live cluster.

#4287 also adds a migration 59. If it merges first, this one moves to
60: the file, the version it stamps, `migrations.targetVersion`, the
bats file (its `run_migration` argument and expected `STAMP`) and
`hack/testdata/migration-59-vmi-hotplug`.

A VM with a pending hotplug request at upgrade time may also get stuck.
virt-controller still processes `VM.status.volumeRequests` before the
declarative handler, and it applies them through the VMI subresource,
which virt-api rejects once the old gate is off. The sync then fails
before the VM spec is updated, so nothing clears the request, and every
later sync of that VM fails the same way. A retry through the VM
subresource edits the spec and clears it, which covers kubevirt-csi's
own requests. A one-shot request stays stuck until the VM restarts. I
read this from the v1.9.0 code and haven't reproduced it. Waiting until
this lists nothing before upgrading narrows the window, but a request
made during the rollout can still hit it:

```bash
kubectl get vm --all-namespaces --output json | jq --raw-output '.items[] | select((.status.volumeRequests // []) | length > 0) | .metadata.namespace + "/" + .metadata.name'
```

The two halves live in different HelmReleases, so there is a short
window during the rollout where the driver and the gate disagree. In
that window an unpublish fails and is retried until both are updated.

A tenant cluster whose `kubernetes` HelmRelease is suspended or failing
keeps its old driver for longer. Drivers from before July 2025 attach
through the VMI subresource, so on such a tenant every attach is refused
until its release reconciles. Such a driver can also attach a volume
after the migration has run and before the gate flips. The migration
doesn't see that volume, and the first declarative reconcile unplugs it
from the running VM.

The migration lists the VMs once and patches each one with a
`resourceVersion` test, so a VM that changes in between fails the hook
Job. The Job has `backoffLimit: 3`, and each retry lists again and skips
the VMs already patched. Re-reading only the conflicting VM would avoid
the retry; I left that out.

The new gate is listed in the CR even though it is on by default. With
the old gate gone it is the only hotplug path, and the chart refuses a
render that disables it. I found no other user of `HotplugVolumes` in
the platform or in the downstream repositories.

The VMI-level fallback may have been failing already. The kcsi Role has
no rule for the VMI-level `removevolume` (#4452), so that call likely
got 403 with or without the gate. I haven't checked that on a cluster.

`hack/migration-59-vmi-hotplug-volumes.bats` runs the migration against
a fake kubectl: a VM that needs the copy, VMs and VMIs that must be left
alone (a VMI that is not Running among them), a second run, a cluster
without KubeVirt and the fail-closed paths. The helm-unittests for the
KubeVirt CR pin the whole gate list, accept `HotplugVolumes` in
`disabledFeatureGates` and refuse `DeclarativeHotplugVolumes` there. The
CSI test pins the flag at false, and the `make update` idempotency test
still passes. None of that exercises hotplug itself. The real test is
e2e with volume attach and detach on a tenant cluster, including a
teardown. No CI lane upgrades from the previous release yet, so an
upgrade with a live VMI-only volume is untested; #4463 tracks that test.

### Release note

```release-note
feat(kubevirt)!: KubeVirt now runs with DeclarativeHotplugVolumes instead of the deprecated HotplugVolumes feature gate, and kubevirt-csi no longer uses the VMI-level hot-unplug. Volume hotplug requests are applied through VM.spec. The upgrade copies volumes that older kubevirt-csi versions attached only to the VMI into VM.spec, so they stay attached; the check in the PR description is optional. This also applies to ephemeral volumes added to running user VMs at the VMI level, such as with virtctl addvolume without --persist: they become part of VM.spec and attach again after a VM restart. virt-api now refuses VMI-level addvolume and removevolume on a VMI owned by a VM, so such volumes are added and removed through the VM. A tenant cluster whose kubernetes release is suspended or failing keeps its old kubevirt-csi, and a driver from before July 2025 cannot attach volumes there until that release reconciles, and a volume it attaches during the upgrade itself can be unplugged again. A values override that puts DeclarativeHotplugVolumes into disabledFeatureGates now fails the kubevirt render. Clusters on the default variant do not run platform migrations and should run that check before upgrading.
```

## What this PR does

An admission policy now refuses a Redis release that would expose a
plaintext endpoint outside the cluster. Redis never turns TLS on by
itself, so `external: true` without `tls.enabled: true` is exactly that
case. The error names the release and a remedy that works.

The rule has three parts, because TLS is fixed when a Redis instance is
created: the RedisFailover schema refuses a change, while the Redis API
accepts one and the HelmRelease then fails. A spec's `tls.enabled` is
therefore a request, not proof of what the instance runs.

- On create, `external: true` needs `tls.enabled: true`.
- On update, turning `external` on is refused whatever `tls.enabled`
says.
- While `external` stays on, `tls.enabled` cannot change. Before the
first reconcile nothing else stops TLS being dropped from a release
admitted as external with TLS. Withdrawing `external` in the same edit
lifts the freeze, and the callers trusted by
`cozystack-tenant-host-policy` are exempt, so an instance whose TLS was
flipped earlier can still be unblocked.

Edits to a release that was already external pass, so releases exposed
in plaintext before this policy keep working. The guarantee covers the
Redis app. A generic publisher such as `tcp-balancer` can still forward
to a plaintext Redis, by design.

This diverges from the Security section of the
`external-database-exposure` proposal, which refuses only an explicit
`tls.enabled: false` and covers every engine. That rule was written
before redis had TLS and matches only postgres. Postgres is left out
here on purpose: CloudNativePG keeps `ssl=on` and its default pg_hba
accepts plaintext from any client that asks, whatever the chart's
`tls.enabled` says, so an admission rule on that field closes nothing.
That gap is #4619. The proposal update and a decision record are
cozystack/community#91.

The policy follows `cozystack-tenant-host-policy`: a
ValidatingAdmissionPolicy in `cozystack-basics`, enforced inside
`cozystack-api` for the aggregated kind. Its decisions are tested in Go
by compiling the shipped template with the apiserver's own CEL compiler
and running Redis objects through it, including the bypass sequences
found in review. A structural chart test can't show what the policy
admits. The redis README, the `external` field description and the
threat model describe the new rule.

Related: #4622 (valkey `external` is always plaintext), #4624 (the redis
`tls.enabled` description implies a live switch).

## Summary by CodeRabbit

* **New Features**
* Redis admission checks now require TLS when external access is enabled
at instance creation. They block enabling external access on an existing
instance and changing TLS while external access remains enabled.
Disabling external access in the same update allows TLS changes.
* Existing instances that already had external access without TLS before
the policy was introduced remain editable.
* **Documentation**
* Updated Redis configuration and security guidance to explain these
restrictions and TLS migration behavior.

Mattia Eleuteri 21fa1fcdb1 feat(postgres): add per-user createRole and bypassRls attributes
Without these, a tenant that needs to manage its own roles has no option
but the postgres superuser, which also hands over filesystem access and
command execution on the instance. Role attributes are not inherited
through role membership, so the generated <db>_admin group role cannot
carry them: they have to be set on the login user itself.

users.<name>.createRole and users.<name>.bypassRls set CREATEROLE and
BYPASSRLS on a managed login user. Both are reconciled on every
init-script run, so setting one back to false emits the NO... form and
revokes the attribute.

createRole is refused on PostgreSQL 15 and older. Before PostgreSQL 16,
CREATEROLE allowed granting membership in any non-superuser role, so a
user holding it could grant itself pg_execute_server_program and reach
command execution on the instance, which is exactly what not exposing
the superuser prevents. PostgreSQL 16 restricted CREATEROLE to roles the
grantee administers. bypassRls carries no such gate: BYPASSRLS only
waives row-level security inside the tenant's own databases, whose owner
already reads every row, so it adds no reach.

The two attributes are needed together, not separately. PostgreSQL only
lets a role create other roles carrying BYPASSRLS if it holds the
attribute itself, so provisioning a privileged service role fails with
"Only roles with the BYPASSRLS attribute may create roles with the
BYPASSRLS attribute" when only createRole is granted.

createRole also sets createrole_self_grant as a role-level default.
PostgreSQL 16 grants a CREATEROLE holder only ADMIN OPTION on the roles
it creates, governed by that parameter, whose default is empty. ADMIN
OPTION allows granting the role onward but not SET ROLE to it, and
creating an object owned by another role requires SET. The attribute
therefore looks functional -- CREATE ROLE succeeds -- while the next
statement a tenant writes, CREATE SCHEMA ... AUTHORIZATION <new role>,
fails with "must be able to SET ROLE". The default is reset when the
attribute is withdrawn.

The init job runs as the superuser, and before this change it trusted
two things a CREATEROLE holder controls for the roles it creates: role
comments and role names. It picked the users and roles to drop by their
comment, and a PostgreSQL 16 CREATEROLE holder may comment every role it
created, then hand it to the chart for deletion. It adopted any role
that already existed under a declared name, so a role created under a
name an administrator declares later stayed under its creator's control.
Neither can be caught from the catalog: creating a role through an
intermediate role and then dropping that role leaves the squatted role
with no member at all, while the objects, settings and default
privileges planted in it stay.

The chart therefore records the roles it manages as members of
"cozystack:managed", a role only the superuser can grant, and the delete
passes act only on those. Its first run marks every role the chart had
commented before, when no role could yet hold CREATEROLE through it.
Once any user has held createRole, recorded as a setting of the postgres
database, the chart refuses to adopt a role it did not mark and fails
with the role's name, rather than hand a squatted role REPLICATION or
the ownership of a database.

Verified against live PostgreSQL instances. On 17 a migration checklist
replayed as the login user, with no superuser: role creation with
attributes, CREATE SCHEMA ... AUTHORIZATION with the requested owner,
extensions in a named schema, per-role search_path and timeouts, RLS
including FORCE ROW LEVEL SECURITY, and SECURITY DEFINER functions all
succeed. On 17 the forged-comment and squatting paths are refused or
ignored, the upgrade from the previous chart marks the roles it already
managed, and a fresh install still adopts the role CNPG bootstraps for
users.app. On 13, 15 and 16 the init script runs and re-runs cleanly.

## What this PR does

Adds a `flavor: postgresql | postgis` enum to the `postgres` app.
`postgis` runs the cluster on the CloudNativePG PostGIS operand image,
so tenants can enable `postgis`, `postgis_raster`, `postgis_topology`,
`postgis_sfcgal`, `postgis_tiger_geocoder` and `address_standardizer`
through the existing `databases.<name>.extensions`. The default stays
`postgresql` and renders exactly the image it rendered before this
change.

This picks up #2672 by @matthieu-robin, which the stale bot closed after
a rebase request, with these changes:

- The postgis tags in #2672 (`17.7-3.5`, `16.11-3.5`, ...) do not exist
in `ghcr.io/cloudnative-pg/postgis`; the registry answers 404, so the
flavor would have ended in `ImagePullBackOff`. The map now uses tags
that exist, `<minor>-<postgis>-standard-trixie`, on the same PostgreSQL
minor as `files/versions.yaml`.
- v18 is supported: PostGIS images for 18 now exist upstream.
- `standard` rather than `system`: the chart archives through the
barman-cloud plugin since the backup rework, so the operand no longer
needs the barman binaries of the deprecated `system` variant.
- `hack/update-versions.sh` derives the postgis map from the minors it
picks, and `hack/check-postgres-postgis-versions.bats` fails if the two
maps drift to different minors or away from `standard-trixie`.
- The chart refuses a flavor change on a live `Cluster`. The default
images are built on Debian bullseye (glibc 2.31) and the postgis ones on
trixie (glibc 2.41): CNPG would roll the swap out as a plain image
update, under an initialised data directory, which silently invalidates
every index on collatable text, and the postgis-to-postgresql direction
also drops the libraries behind every PostGIS object. Only the image
name is compared, so minor bumps and registry mirrors keep passing.
- `pgrouting` is not claimed: it is absent from the `18.1-3.6.1` build
the chart pins and only appears in later postgis builds.

A general mechanism (CNPG ImageVolume extensions) was considered and
left out: it needs PostgreSQL 18 and Kubernetes 1.35 or the
`ImageVolume` gate, so it cannot serve v13-v17 nor most management
clusters today, and PostGIS is the only extension CloudNativePG ships as
a full operand image. No other extension request exists in this
repository.

Testing:

- `helm unittest packages/apps/postgres`: 145/145, including 6 new cases
in `tests/flavor_test.yaml` (default image, postgis on the Cluster and
on the init Job, the guard in both directions with a mocked live
Cluster, and a mirrored digest-pinned image taking a new minor).
Removing the guard makes exactly the two guard cases fail.
- `hack/cozytest.sh hack/check-postgres-postgis-versions.bats` passes,
and fails on a shifted minor or a `system` tag.
- `make -C packages/apps/postgres generate` leaves no diff.
- The rendered
`ghcr.io/cloudnative-pg/postgis:18.1-3.6.1-standard-trixie` was started
locally: `CREATE EXTENSION` for citext, postgis, postgis_raster and
postgis_topology succeeds and `ST_Buffer` answers. A three-instance
cluster on the `system` sibling of that image has been running PostGIS
in production since 2026-09-29.

feat(postgres): add a `flavor` field accepting `postgresql` (default) or `postgis`. `postgis` bootstraps the cluster from the CloudNativePG PostGIS image, so PostGIS extensions can be enabled per database through `databases.<name>.extensions`. The flavor is fixed at creation: changing it on an existing cluster is refused, and so is restoring a backup into a cluster of the other flavor, whether through a RestoreJob or `bootstrap.enabled`; move data across flavors with a logical dump.

each match stanza into an interface literally named after the netplan
ID, so a non-netplan guest left on the default profile would lose the
DHCP it gets today. A VM with neither cloudInit nor sshKeys would also
gain a cloud-init disk on upgrade, and KubeVirt's NoCloud instance-id
is new to that guest, so its next boot would regenerate host keys as a
first boot.

The configuration also shadows a static NIC set up through netplan:
netplan emits one networkd file per ID, networkd applies only the first
file in lexical order that matches a link, and 10-netplan-cozy-en sorts
before the file for enp2s0. The external-VLAN recipe claimed otherwise.

An explicit netplanDhcp value, off by default, leaves every existing
VM rendering exactly as before and lets the documentation say when not
to turn it on.

Mattia Eleuteri b5181b0b9b fix(vm-instance): supply cloud-init network-data to netplan guests
A netplan guest configures only the interface cloud-init's fallback
configuration covers, and keeps none of the search domains DHCP offers
it, so two things the platform already puts on the wire never reach it.
virt-launcher runs a DHCP server on every bridge-bound interface,
secondary ones included, yet a VM joined to a VPC subnet leaves that
interface inert for want of a client asking. The same server advertises
the launcher pod's search domains as option 119, which systemd-networkd
discards because UseDomains= defaults to no, and a cluster domain under
.local then falls through to the mDNS exclusion in resolved and answers
REFUSED.

The virtual-machine chart carried a network-data template for the first
of those, gated on systemDisk.image. Splitting that chart into vm-disk
and vm-instance removed the template along with the field it read, and
neither came back.

Matching en* and eth* rather than naming interfaces by index keeps the
configuration correct whatever the guest enumerates its NICs as, which
is where the previous template was fragile.

Alexey Artamonov e63b9e439c fix(monitoring): count a central request as the receiver admitted it
The limiter refuses for good any request it counts above burst, and
burst was the receiver's 4 MiB cap. A request grows on its way to the
limiter: the sampler adds a tracestate to every span it keeps, and the
limiter counts a request as the collector re-encodes it, which writes
the empty value of every attribute the wire may omit, so a valid
request of spans with empty-valued attributes is counted 1.4x. A
request the receiver admitted near its cap was therefore refused on
every retry.

The limiter now runs right after memory_limiter, so it counts the
request before sampling. The receiver caps a request at 3 MiB and
burst stays at 5 MiB, which holds 1.4x the cap; a larger burst would
also be what each pod start lets through above the rate. The rate is
counted before sampling, so the store keeps only the sampled share of
it. The texts say that a request above the cap gets a 400, which
senders do not retry, and that each collector rollout a tenant causes
lets that burst through again on every pod.

The replica bound that keeps that allowance small now applies only to
a central tenant's collector, whose render fails above ten replicas: a
collector writing to the tenant's own store has no rate, and the
replica counts it shipped with stay valid.

Alexey Artamonov 177b207a27 feat(monitoring): hold each shared-central tenant to a write rate
The design has the per-tenant collector rate-limit its tenant, so that
a noisy or hostile tenant cannot exhaust a shared backend. The disk cap
alone does not do that: VictoriaTraces always keeps the last two days,
so a tenant writing faster than the cap allows over two days fills the
disk for every tenant on the store.

The platform sets the rate with
monitoring.tracingCentralTenantBytesPerSecond, and it reaches every
tenant in _cluster through the cozystack-values Secret. A change there is a change in the values each
monitoring HelmRelease reads, so Flux upgrades them all; a rate read
with lookup at render time would never reach a tenant whose release is
already in sync. The platform writes the key only when it is set, since
every release in every tenant reads that Secret. Without it the
collector holds the tenant to the rate of a default 10Gi store.

Each central tenant's collector splits the rate across its replicas
and refuses data above it before the batch processor, so the sender
sees the refusal. An OTLP/HTTP sender gets a 429 and retries; the
limiter answers gRPC with RESOURCE_EXHAUSTED and no RetryInfo, which
the OTLP specification makes final, so central tenants should export
over HTTP.

Aleksei Sviridkin f4a6eb809c fix(nats): enable JetStream for the generated account (#4675)
## What this PR does

With `users` configured and `jetstream.enabled: true`, the application
chart enables JetStream on the server but generates account `A` without
it. Authentication and ordinary NATS messaging work, while
`$JS.API.INFO` returns error 10039, "JetStream not enabled for account".

The generated account now gets `jetstream: true` when persistent
messaging is enabled and the account does not set JetStream itself.
Tenant-supplied limits, explicit disablement, other accounts and the
existing generated-user merge are kept. nats-server matches config keys
case-insensitively and walks the account map in no fixed order, so a
`JetStream` key in any casing counts as set. Otherwise the account would
carry both keys and the server would apply either one, changing from
restart to restart.

Existing instances with `users` pick this up on upgrade. The rendered
NATS config changes, so the StatefulSet rolls its pods once, and account
`A` gets JetStream without account limits unless
`config.merge.accounts.A.jetstream` sets them.

### Validation

- `helm unittest` passes all 75 application-chart tests. Eight cases
cover this change. Against the original template the generated-account
and null-override cases fail. The other six pin what the change must
keep, and the mixed-case one fails as soon as the check is
case-sensitive.
- Dropping the `jetstream.enabled` check, the case folding or the
explicit-setting check turns at least one case red each time.
- The application chart and the vendored system chart were rendered, and
the resulting account configuration was run on NATS Server 2.11.10 in an
isolated standalone setup. The original template reproduces error 10039.
With this change a file-backed stream can be created, published to and
read, and explicit disablement and a one-stream limit stay enforced.
- `make generate` with cozyvalues-gen v1.7.0 leaves the generated files
unchanged.

### Screenshots

Not a UI change.

### Downstream repositories

The diff changes an application template and chart tests only. Public
values, schemas, output resource names and tooling contracts are
unchanged. The website NATS documentation contains no account-level
workaround to remove. No downstream trigger applies.

### Release note



```release-note
fix(nats): enable JetStream on the account generated for users when jetstream.enabled is true, keeping any explicit account-level JetStream setting. Instances with users roll their NATS pods once on upgrade.
```

## Summary by CodeRabbit

* **Bug Fixes**
* Generated NATS accounts now enable JetStream when configured, without
overriding an existing JetStream setting. Configured passwords are added
while preserving existing account settings.

* **Tests**
* Added coverage for enabled and disabled JetStream, explicit limits and
false or empty values, case-insensitive setting names, null overrides,
and manually configured accounts when generated users are absent.
