At `0o600` the game process couldn't read its own mods. This is the rationale behind the `.golangci.yml` gosec G302 exclusion scoped to `agent/internal/mods/mods.go`. - **Resource usage is in-pod**: The `usage` package reads from `/proc` or cgroups; no external metrics pipeline required. Cgroup mode is a fallback for older clusters; proc mode (default in production) requires the operator to set `ShareProcessNamespace: true`. - **Module capabilities drive behavior**: Every game-specific handler (players, quiesce, lifecycle, status, actions) reads its config from `--capabilities` (JSON unmarshaled into `caps.Spec`). New games require no agent code change. +- **Backup process identity**: The operator injects `GAMEPLANE_POD_UID` from `metadata.uid` through the DownwardAPI. Pod-bound backup routes require the existing mTLS authentication and check this UID at the final network hop, including when the Service resolves to a replacement pod. Missing UID fails closed. Deploy the updated agent image and allow pod rollout when upgrading the operator; older agents return 404 and the operator does not fall back to unbound routes. Legacy endpoints remain available to existing callers during rollout. - **RCON connection errors are graceful**: A lost RCON connection does not crash the agent. `console`, `players`, `quiesce`, and `lifecycle` handlers catch connection errors and return appropriate HTTP status (e.g., `502 Bad Gateway`). - **Source RCON sends complete frames**: Each AUTH or command frame is submitted in one socket write, with its existing byte-size limit, request ID, type, body, and two NUL terminators preserved. This avoids separate header-only writes rejected by vanilla Minecraft's RCON reader. A short write is an error and drops the connection without replaying the command; response grace and healthy connection reuse remain unchanged. - **Log streams are tail-only**: The `logs` package does not support random-access reads. It streams from the current end (live mode) or from file start (backlog mode); clients must handle partial output and reconnection. diff --git a/api/go.mod b/api/go.mod index 4d5083c09..56ba6a627 100644 --- a/api/go.mod +++ b/api/go.mod @@ -86,7 +86,7 @@ require ( github.com/jackc/pgservicefile v0.0.0-20240606120523-5a60cdf6a761 // indirect github.com/jackc/puddle/v2 v2.2.2 // indirect github.com/json-iterator/go v1.1.12 // indirect - github.com/klauspost/compress v1.20.1 // indirect + github.com/klauspost/compress v1.20.2 // indirect github.com/klauspost/cpuid/v2 v2.4.0 // indirect github.com/klauspost/crc32 v1.3.0 // indirect github.com/mattn/go-isatty v0.0.24 // indirect @@ -110,7 +110,7 @@ require ( go.uber.org/zap v1.28.0 // indirect go.yaml.in/yaml/v2 v2.4.4 // indirect go.yaml.in/yaml/v3 v3.0.5 // indirect - golang.org/x/net v0.60.0 // indirect + golang.org/x/net v0.62.0 // indirect golang.org/x/term v0.47.0 // indirect golang.org/x/time v0.15.0 // indirect gomodules.xyz/jsonpatch/v2 v2.5.0 // indirect diff --git a/api/go.sum b/api/go.sum index 375f7a5a0..1eb60b7e3 100644 --- a/api/go.sum +++ b/api/go.sum @@ -95,8 +95,8 @@ github.com/jackc/puddle/v2 v2.2.2 h1:PR8nw+E/1w0GLuRFSmiioY6UooMp6KJv0/61nB7icHo github.com/jackc/puddle/v2 v2.2.2/go.mod h1:vriiEXHvEE654aYKXXjOvZM39qJ0q+azkZFrfEOc3H4= github.com/json-iterator/go v1.1.12 h1:PV8peI4a0ysnczrg+LtxykD8LfKY9ML6u2jnxaEnrnM= github.com/json-iterator/go v1.1.12/go.mod h1:e30LSqwooZae/UwlEbR2852Gd8hjQvJoHmT4TnhNGBo= -github.com/klauspost/compress v1.20.1 h1:T7kKElXUMXrUJ2E9QhQhxFtcK5rPyLdsGZvdbLMPdiQ= -github.com/klauspost/compress v1.20.1/go.mod h1:LUdAzn7YLVvxLpc7y3V1m40wESHTgc1422pwwBSKYuI= +github.com/klauspost/compress v1.20.2 h1:v5tiZvm1KGLyg5d5oXdXe3lsSPrbEUiKoXGia//I7Qo= +github.com/klauspost/compress v1.20.2/go.mod h1:LUdAzn7YLVvxLpc7y3V1m40wESHTgc1422pwwBSKYuI= github.com/klauspost/cpuid/v2 v2.0.1/go.mod h1:FInQzS24/EEf25PyTYn52gqo7WaD8xa0213Md/qVLRg= github.com/klauspost/cpuid/v2 v2.4.0 h1:S6Hrbc7+ywsr0r+RLapfGBHfyefhCTwEh3A0tV913Dw= github.com/klauspost/cpuid/v2 v2.4.0/go.mod h1:19jmZ9mjzoF//ddRSUsv0zfBTJWh3QJh9FNxZTMrGxU= @@ -191,8 +191,8 @@ golang.org/x/crypto v0.58.0 h1:COkYLr4k7nDI4r6QtMML2AfzeIswWHAJthLS6K/M/54= golang.org/x/crypto v0.58.0/go.mod h1:Xh+kl5A+M0gMiWDytH2Hhr5Z7WbNCpv/eB/EFgfSk+w= golang.org/x/mod v0.42.0 h1:ICeL3t2L30ljSPHHxDnR4fqVcBt/zR2zJAb9juavmQg= golang.org/x/mod v0.42.0/go.mod h1:u5fzIrRInkL8MaO1cbRkUHT64v303YIT5KEqpNr7jRs= -golang.org/x/net v0.60.0 h1:79p50tfZlm0J9YfoDsSi639qSXNGVwEzOPLCxM2FsYU= -golang.org/x/net v0.60.0/go.mod h1:2DA/G1UfVbCpQPeWTmMPGY7Cs2PkBkwu743bVX5PIVg= +golang.org/x/net v0.62.0 h1:18ELalfM5+XNRwzM2nYqXsZQ9ByS1uhj2O/U7+5jqRY= +golang.org/x/net v0.62.0/go.mod h1:WgDCOTH8iwtB66T4/GfI94AHo/hhdb7Hah9NDseQfiI= golang.org/x/oauth2 v0.37.0 h1:JUlcxA8oAtauLfiH8FX2/FkAWHAdi0QtGCGc+hofE98= golang.org/x/oauth2 v0.37.0/go.mod h1:IxwZNxUULJmpBFf9K/9NTMSIfZZuvuTy1gGxhigP/58= golang.org/x/sync v0.24.0 h1:iqiDrGoDgyuvAKrhLQthUEzU/R378N78gXbBjxed7oA= diff --git a/docs/operator-operations.md b/docs/operator-operations.md index 1a90d084e..73785fcf2 100644 --- a/docs/operator-operations.md +++ b/docs/operator-operations.md @@ -5,6 +5,13 @@ including backups with `quiesce: false` and CSI VolumeSnapshots.

Current copy workers are excluded by Job ownership. This path sends no agent calls and preserves suspend/idle/wake intent under the shared workload fence. It applies equally to restic and CSI copies. + - Live preparation also pins the game Pod UID. The operator checks the agent's read-only `/v1/pods/{uid}/identity` endpoint before recording the first cleanup intent, then uses pod-bound quiesce/unquiesce routes; the agent rejects a different UID before RCON. A missing endpoint or identity mismatch fails closed without a legacy-route fallback. Ambiguous quiesce errors retain cleanup intent and the original Pod UID on both the Backup and shared owner. Only confirmed save-on or uncached evidence that the original pod is absent/replaced/terminal permits cleanup; an HTTP timeout, unready pod, or terminating pod is insufficient. Legacy attempts without a UID retire only on absence/terminal proof and never adopt a new UID. `Unquiesced=True, Reason=SourceProcessGone` distinguishes process exit from an actual save-on RPC. + - Source proof is checked before and after quiesce and on each copy reconcile. Observed workload/process replacement fails the Backup before it can report a restorable success.

Older agents fail the identity preflight before cleanup debt, so the workload can continue its upgrade after terminal cleanup releases the owner. Retry failed copies after rollout; preflight never bypasses protection. This does not automatically stop a running game. - Every copy, including `quiesce=false` and CSI snapshots, acquires the shared lifecycle owner before starting. The Backup pins its target in `backup.gameplane.local/target`; `backup.gameplane.local/owner` remains a compatibility marker. The shared owner is described below. Quiesce cleanup intent is recorded on both the Backup and the surviving GameServer before calling the agent, including partial failures. Cleanup waits for live copy workers; deletion cancels the copy Job with foreground propagation first. Every Backup carries the cleanup finalizer. Pre-upgrade quiesced workers are observed through completion even when overlapping legacy copies cannot acquire the new exclusive owner. - Orphan recovery preserves predecessor operation identities in the shared owner's `recovery` array, atomically with ownership transfer. Existing `backup.gameplane.local/recovering-owners` lineage is imported during migration. Deleting a recovering owner cannot hide an earlier worker. Normal deletion, orphan recovery, and legacy cleanup also wait for pending owned CSI captures to report ready or an explicit error; VolumeSnapshots are reclaimed by owner-reference GC after cleanup. - VolumeSnapshot API availability is checked before quiescing. Snapshot creation errors fail the Backup and run unquiesce cleanup immediately instead of retrying creation indefinitely with saving disabled. API/creation failures persist `backup.gameplane.local/snapshot-aborted` to allow cleanup without waiting for a failed/nonrestorable capture. Failed unquiesce remains visible and retried.
