Learning: In the server package, when quotas are enabled via config.Get().System.Quotas.Enabled, the disk space check using used >= s.DiskSpace() does not require a special guard for unlimited-disk scenarios (DiskSpace() <= 0). The filesystem handles such cases, so the existing check is sufficient. Apply this pattern to similar quota-related disk checks in the server package and ensure tests/docs reflect that unlimited-disk behavior is governed by the filesystem, not by an extra guard in code.

There was a problem hiding this comment.
Security regression: Filecmd lost the egg denylist check.
On main, Filecmd starts with h.fs.IsIgnored(request.Filepath); that check was removed here with no replacement (only Fileread/Filewrite kept theirs). The underlying Filesystem.Rename/Delete/Chmod/Symlink don't enforce the denylist either (Delete calls RemoveAll, not SafeDeleteRecursively), so an SFTP user with file.update/file.delete can now Setstat/Rename/Rmdir/Remove/Symlink denylisted files — and renaming a denylisted file to a non-matching path then defeats the remaining read/write checks too. This is strictly weaker than the HTTP API, which checks both sides of a rename.
Suggested fix — restore the check (and also cover the target path, which main didn't):
if err := h.fs.IsIgnored(request.Filepath); err != nil {
return sftp.ErrSSHFxNoSuchFile
}
if request.Target != "" {
if err := h.fs.IsIgnored(request.Target); err != nil {
return sftp.ErrSSHFxPermissionDenied
}
}The PR description mentions the denylist removal will be fixed later, but since it's an access-control regression it seems worth fixing before merge rather than after.

ResolveToken(true) can permanently desync wings from the Panel after a token rotation.
Scenario: an operator pins credentials via WINGS_TOKEN/WINGS_TOKEN_ID (previously a silent, supported override). A Panel admin then resets the node token: the Panel's NodeUpdateService authenticates with the old token but pushes the new one. This endpoint now 500s with does not match environment override before WriteToDisk — but the Panel only catches ConnectionException, so it commits the new token on its side anyway. Result: every wings→Panel request 401s, and every subsequent config push (even ones not touching tokens) keeps failing until someone hand-edits the env var. Pre-PR, the update was applied and the env override kept winning, which left a recovery path.
Suggested fix: on an env-override mismatch, don't reject the push — accept and persist the Panel's config (the env override still wins at runtime, as before) and log a warning that the override is now stale. That keeps the operator informed without letting the two sides permanently disagree.

There was a problem hiding this comment.
Recomputing the quota from current config silently disables bursting for existing containers after a cpu_period change.
This duplicates the formula in environment/settings.go (drift risk), but the real problem: if an admin raises docker.cpu_period and restarts wings, Start's already-running branch computes a burst from the new period that exceeds the container's creation-time quota — the kernel rejects the cpu.max.burst write with EINVAL (burst > quota), and after the single sync.Once warning every failure is debug-level, so bursting is silently absent fleet-wide until containers are rebuilt.
Suggested fix: use the container's actual quota instead of recomputing it. SetCpuBurst already does a ContainerInspect — read c.HostConfig.Resources.CPUQuota from that result (exactly what server/install.go already does) and drop the quota parameter/recomputation here.

There was a problem hiding this comment.
Cgroup path resolution breaks when wings itself runs in a container (a shipped deployment — this repo has a Dockerfile), and the failure warning is misleading.
Per cgroup_namespaces(7), /proc/<pid>/cgroup paths are rendered relative to the reader's cgroup namespace. Host-installed wings sees full host paths and works, but containerized wings fails on several fronts: with a private cgroupns the target's path renders as /../..., which this .. filter skips (→ “no cpu controller found”); without host PID namespace /proc/<host-pid> isn't even the right process; and the container's /sys/fs/cgroup mount typically exposes only its own subtree. With cpu_burst.enabled defaulting to true, every containerized install logs one false “requires Linux 5.14 or newer” warning and the feature silently never works.
Separately, nothing validates that the resolved path belongs to the target container before os.WriteFile — a crashed container plus PID reuse between inspect and write would mutate an unrelated cgroup. A cheap guard for both: verify the resolved path contains the container ID (holds under both /docker/<id> and docker-<id>.scope layouts), and mention cgroup-namespace visibility in the warning text.

There was a problem hiding this comment.
Redundant second ContainerInspect — both hot call sites already hold a fresh inspect result.
InSituUpdate and Start's already-running branch both call e.ContainerInspect and even read c.State.Pid right before applyCpuBurst, which then re-inspects the same container just to re-obtain the pid — doubling Docker API round-trips per limit update and per boot-time reattach. It also uses the raw client's slow JSON decoder, bypassing the optimized (*Environment).ContainerInspect fast path this project added specifically for this endpoint.
Suggested fix: pass the known pid (and, per the other comment, the actual quota) through from callers — clearCpuBurst(pid) already models the shape. Only the post-ContainerStart site in power.go genuinely needs its own inspect.
Refactor metadata structure to include 'from' and 'to' keys.

A container reattached through this running-container path retains its previous CPU burst allowance even when docker.cpu_burst.enabled is false. applyCpuBurst reaches SetCpuBurst, but the disabled path returns without writing 0 to the existing cgroup burst file, so the new configuration cannot disable bursting until a resource update or container recreation; ensure the disabled path explicitly clears the burst value.

133-133: Clamp or reject CPU quotas below Docker’s minimum.A
CpuLimitof1with a1,000µsperiod produces a10µsquota. Moby v28.5.2 rejects positive CPU quotas below1,000µs, so container creation or updates fail for this valid configuration. Clamp the quota or reject this configuration before calling Docker. (raw.githubusercontent.com)environment/docker/cgroup_burst.go (4)
44-44: Handle cgroup paths outside Wings’ namespace root.When Wings runs in a private cgroup namespace,
/proc/<pid>/cgroupcan contain/../...for processes outside that namespace root. The resolver rejects paths containing.., so it cannot apply the burst in that deployment. Resolve paths using the visible cgroup mount, or report this layout as unsupported. (man7.org)
55-55: Resolve the mounted v1 CPU controller path.The
cpu,cpuaccttest case maps to/sys/fs/cgroup/cpu/.... On hosts that mount the combined controller at/sys/fs/cgroup/cpu,cpuacct, the write targets a missing path and bursting does not take effect. Resolve the mount point instead of assuming its directory name.
80-80: 🔒 Security & Privacy | 🛡️ Detected with Advanced TierExploitability: Difficult
CWE: CWE-367 — Time-of-check Time-of-use (TOCTOU) Race ConditionVerify that the cgroup write stays scoped to the inspected container.
SetCpuBurstobtains a PID throughContainerInspect, then the writer reads/proc/<pid>/cgroupand writes the resolved file. If the process exits and the PID is reused before that read, the write could change another container’s CPU burst. Does the writer verify the container identity beforeos.WriteFile? If not, add that check.#!/bin/bash set -euo pipefail rg -n -C 8 'SetCpuBurst|writeBurstFile|resolveCgroupCpuFile|os\.WriteFile|ContainerInspect' \ environment/docker/cgroup_burst.go environment/docker/container.go \ environment/docker/power.go server/install.go
121-121: Use the container’s actual quota when applying burst.
applyCpuBurstderives quota from the current configuration, but an existing container retains the quota set when it was created. Aftercpu_periodchanges, the calculated burst can exceed that quota. The kernel limitscpu.max.burstto the current quota, so the write fails and bursting remains disabled. Use the inspected container’s actual quota. (kernel.org)environment/docker/container.go (1)
140-141: Restore the burst whenContainerUpdatefails.
InSituUpdateclears the burst beforeContainerUpdate, but reapplies it only after success. If the update fails, the running container keeps a zero burst until a later update or restart. Reapply the previous burst on the error path.environment/docker/power.go (1)
