What this PR does

Fixes #4968. The cilium IPAM migration hook passed the whole kubectl get ciliumnodes -o json to jq as one argument, and Linux allows 128 KiB for a single argument. Cilium copies Node labels onto every CiliumNode (22 to 30 KiB per node with Talos, NFD or GPU labels), so the list is over the limit within six nodes. jq can't start (Argument list too long), the hook Job fails before it moves any node, cilium HelmRelease loops on UpgradeFailed and everything that depends on networking stays in DependencyNotReady.

The hook is rendered on every upgrade of cilium in cluster-pool mode, so a cluster that already finished the migration hits the same on its next values change. The failing step only logs the pods that still hold an old Ingress IP, but it runs before the node loop, so on a cluster that is not migrated yet it blocks the migration itself.

Now the list goes to jq on stdin together with the IP objects, same as the other jq calls in the script get their input.

The new test in hack/cilium-ipam-migration.bats makes six CiliumNodes over the limit (one 24 KiB annotation each instead of labels, and it checks the list is over 128 KiB even printed compact). It fails on the old script with status 126 and passes now. It also checks that each pod is named with the node whose Ingress IP it holds and that a pod on an unrelated address is not named, because a join that always names the first node, or reports every IP object, passed the old tests.

I did not take two suggestions from the issue. Skipping the hook when every CiliumNode is in the pool changes what one existing test pins (the hook adds the pool to excludeIps in that case) and doesn't help clusters that are not migrated yet. A value to disable the hook leaves the default broken. cozystack-operator rewriting disableHooks and helm-controller rolling the DaemonSet on every retry are other components. The bug is in release-1.6 and release-1.7 as well.

Downstream repositories

I walked the trigger map against the diff (one hook script and its bats test): no package, values, schema, default or output name changed.

Release note

fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking.

Summary by CodeRabbit

  • Bug Fixes
    • Improved IP address migration handling for environments with large node lists, avoiding failures caused by operating system argument-size limits.
    • Migration continues to identify affected pods by node and distinguish unrelated pods.
  • Tests
    • Added coverage for migrations involving large node lists, multiple IP objects, and unrelated pods.

The hook fed the whole `kubectl get ciliumnodes -o json` to jq as one
argument. Cilium copies every Node label onto its CiliumNode, 22 to 30
KiB per node on Talos or with NFD and GPU labels, so the list passes the
128 KiB Linux allows a single argument within six nodes. jq then fails
to start with "Argument list too long", the hook Job fails before it
moves any node, and the cilium HelmRelease loops on UpgradeFailed with
the HelmReleases behind it stuck in DependencyNotReady.

The hook renders on every upgrade of cilium in cluster-pool mode, so a
cluster that already finished the migration hits the same failure on its
next values change.

Walkthrough

The migration now supplies the CiliumNode list to jq through standard input instead of a command-line JSON argument. A regression test uses a list larger than 128 KiB and checks node migration and ingress-IP matching.

Changes: Cilium IPAM migration

Layer / File(s) Summary
Read large inputs and verify migration
packages/system/cilium/files/ipam-migration.sh, hack/cilium-ipam-migration.bats
The jq lookup reads the CiliumNode list and IP-object list from standard input. The test checks migration and ingress-IP matching with a CiliumNode list larger than 128 KiB.

Estimated code review effort: 2 (Simple) | ~10 minutes

Full details: Title check

Explanation

The title names the main change: the CiliumNode list is now passed to jq on stdin in the IPAM hook instead of as a single argument. The raw summary and PR objectives both describe this change, and it addresses the 128 KiB argument-limit failure in linked issue #4968. The title is specific, concise, and uses a conventional commit format.

Full details: Linked Issues check

Explanation

Directly linked issue #4968 requires that the IPAM migration hook not pass the full CiliumNode list as one jq argument, and that a regression test cover a list over 128 KiB. At head, packages/system/cilium/files/ipam-migration.sh no longer uses --argjson for the CiliumNode list. The list goes to jq on stdin, followed by the IP objects, read with 'input as $cn' and 'input[]'. The same jq expression logic is kept, and the IP objects input is always present because the preceding jq -c call always emits an array, so 'input[]' does not fail on an empty list. The other CiliumNode uses in the script (check_capacity, exclude_from_kube_ovn) pass the list to bash functions, which have no exec argument limit, or use herestrings. No other exec call takes the full list. hack/cilium-ipam-migration.bats adds a test that builds six CiliumNodes with a 24 KiB annotation each, asserts the compact list is over 131072 bytes, runs the script, and checks that each pod is named with the node whose Ingress IP it holds (web-0 with n1, web-1 with n4) and that an unrelated address (db-0) is not named. This covers the regression case the issue asks for. The issue's note that later upgrades rerun the hook is covered, because the fixed script is the one rendered for every run. Limitation: I read the code and test but did not execute bats or jq, so the reported status 126 on the old script rests on the author's account.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base touches two files only: packages/system/cilium/files/ipam-migration.sh (the single jq call that took the CiliumNode list as --argjson, now fed on stdin, with an explanatory comment) and hack/cilium-ipam-migration.bats (one new regression test). Both changes directly implement #4968. No values, schema, package metadata, default, or output name changed, which matches the PR's downstream statement. The PR description's decisions not to skip the hook, add a disable value, or change cozystack-operator or helm-controller behavior are scope exclusions, and the diff contains none of those changes. No unrelated change was found.

LGTM.

The fix is correct and complete, and the new test earns its place.

On the idiom itself: exclude_from_kube_ovn now hands the CiliumNode list to jq on stdin as a second input, next to the IP objects, instead of through --argjson. I ran the old form and the new two-input form on the same data and got identical output on a normal list (web-0 resolves to n1, web-1 to n4, an unrelated address is dropped). The new filter reads the two values in the right order: CiliumNodes into $cn, IP objects into input[].

The root cause checks out. Under the old form the whole list is a single argv element, so on Linux it trips MAX_ARG_STRLEN (128 KiB) once a few label-heavy CiliumNodes push it over, which is what the issue describes. I couldn't reproduce the execve failure on macOS/BSD, since there's no per-argument cap there, so the new test is a Linux-specific guard. That's fine, the hook runs in a Linux Job.

I also checked where else the list flows, because that's where this kind of fix tends to be half-done. $ciliumnodes is read again by check_capacity (ipam-migration.sh:357, as jq ... <<<"$1") and at lines 178 and 360, and the IP objects at line 232, all via here-string stdin rather than as arguments. Line 248 was the only spot passing the large list as one argument, so nothing of the same shape is left behind.

Tests pass, the whole hack/cilium-ipam-migration.bats is green at 28/28. The new case reproduces at the real threshold (it asserts the compact list is over 131072 bytes) and it pins the join, not just the exit code: each pod is named with the node whose Ingress IP it holds, and a pod on an unrelated address is not named at all. A filter that always named the first node, or reported every IP object, would fail it.

On CI for the head, Unit & controller tests and Build packages/system/cilium are both green. E2E (in-tree) was still running when I looked, nothing red.

Minimal diff, matches issue #4968, and the downstream analysis holds: only the hook script and its test change.

## What this PR does

Fixes #4968. The cilium
IPAM migration hook passed the whole `kubectl get ciliumnodes -o json`
to `jq` as one argument, and Linux allows 128 KiB for a single argument.
Cilium copies Node labels onto every CiliumNode (22 to 30 KiB per node
with Talos, NFD or GPU labels), so the list is over the limit within six
nodes. `jq` can't start (`Argument list too long`), the hook Job fails
before it moves any node, `cilium` HelmRelease loops on `UpgradeFailed`
and everything that depends on networking stays in `DependencyNotReady`.

The hook is rendered on every upgrade of cilium in `cluster-pool` mode,
so a cluster that already finished the migration hits the same on its
next values change. The failing step only logs the pods that still hold
an old Ingress IP, but it runs before the node loop, so on a cluster
that is not migrated yet it blocks the migration itself.

Now the list goes to `jq` on stdin together with the IP objects, same as
the other `jq` calls in the script get their input.

The new test in `hack/cilium-ipam-migration.bats` makes six CiliumNodes
over the limit (one 24 KiB annotation each instead of labels, and it
checks the list is over 128 KiB even printed compact). It fails on the
old script with status 126 and passes now. It also checks that each pod
is named with the node whose Ingress IP it holds and that a pod on an
unrelated address is not named, because a join that always names the
first node, or reports every IP object, passed the old tests.

I did not take two suggestions from the issue. Skipping the hook when
every CiliumNode is in the pool changes what one existing test pins (the
hook adds the pool to `excludeIps` in that case) and doesn't help
clusters that are not migrated yet. A value to disable the hook leaves
the default broken. `cozystack-operator` rewriting `disableHooks` and
helm-controller rolling the DaemonSet on every retry are other
components. The bug is in release-1.6 and release-1.7 as well.

### Downstream repositories

I walked the trigger map against the diff (one hook script and its bats
test): no package, values, schema, default or output name changed.

## What this PR does

Backports to `release-1.7` from `main`, picked by the rules of the
[backport
policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md)
in merge order. A merged pull request comes as its own commits, picked
with `git cherry-pick -x` so each keeps its author, message and
sign-offs, and a merge commit that carries the original's merge message
with a `Backported-from:` trailer naming it; a squash-merged one comes
as one pick. `backport-batch verify` checks that shape. A pick listed as
changed differs from the commit it came from; `git range-diff
<merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A
conflict or a failing check here is a [backport
task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md).

### Release note

```release-note
fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository.

fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout.

fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line

fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member.

fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade.

fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint.

fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...@sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time.

fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back.

fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking.

fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts.

fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result.

fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand.

fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing.

fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret.

fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain.

fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged.

fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane.

fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged.

fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase.

fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading.

fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix.

fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring.

## What this PR does

Fixes #4968. The cilium
IPAM migration hook passed the whole `kubectl get ciliumnodes -o json`
to `jq` as one argument, and Linux allows 128 KiB for a single argument.
Cilium copies Node labels onto every CiliumNode (22 to 30 KiB per node
with Talos, NFD or GPU labels), so the list is over the limit within six
nodes. `jq` can't start (`Argument list too long`), the hook Job fails
before it moves any node, `cilium` HelmRelease loops on `UpgradeFailed`
and everything that depends on networking stays in `DependencyNotReady`.

The hook is rendered on every upgrade of cilium in `cluster-pool` mode,
so a cluster that already finished the migration hits the same on its
next values change. The failing step only logs the pods that still hold
an old Ingress IP, but it runs before the node loop, so on a cluster
that is not migrated yet it blocks the migration itself.

Now the list goes to `jq` on stdin together with the IP objects, same as
the other `jq` calls in the script get their input.

The new test in `hack/cilium-ipam-migration.bats` makes six CiliumNodes
over the limit (one 24 KiB annotation each instead of labels, and it
checks the list is over 128 KiB even printed compact). It fails on the
old script with status 126 and passes now. It also checks that each pod
is named with the node whose Ingress IP it holds and that a pod on an
unrelated address is not named, because a join that always names the
first node, or reports every IP object, passed the old tests.

I did not take two suggestions from the issue. Skipping the hook when
every CiliumNode is in the pool changes what one existing test pins (the
hook adds the pool to `excludeIps` in that case) and doesn't help
clusters that are not migrated yet. A value to disable the hook leaves
the default broken. `cozystack-operator` rewriting `disableHooks` and
helm-controller rolling the DaemonSet on every retry are other
components. The bug is in release-1.6 and release-1.7 as well.

### Downstream repositories

I walked the trigger map against the diff (one hook script and its bats
test): no package, values, schema, default or output name changed.

## What this PR does

Backports to `release-1.7` from `main`, picked by the rules of the
[backport
policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md)
in merge order. A merged pull request comes as its own commits, picked
with `git cherry-pick -x` so each keeps its author, message and
sign-offs, and a merge commit that carries the original's merge message
with a `Backported-from:` trailer naming it; a squash-merged one comes
as one pick. `backport-batch verify` checks that shape. A pick listed as
changed differs from the commit it came from; `git range-diff
<merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A
conflict or a failing check here is a [backport
task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md).
