* fix(sync): mark node dirty inside the mutation transaction
ConfigDirty is currently set by MarkNodeDirty AFTER the mutation, on a
separate DB handle outside the mutation's transaction. A crash or error
between the committed change and the mark leaves a committed config
change that never reconciles to the node (silent drift). Add
MarkNodeDirtyTx(tx, id) and call it inside each mutation's transaction so
the dirty mark commits atomically with the change.
* fix(test): initialize DB in TestResolveInboundAddress and group gorm import
Two CI failures on this branch:
- race (-shuffle=on): TestResolveInboundAddress reaches resolveInboundAddress -> configuredPublicHost -> GetSubDomain, which reads the global DB. The test never initialized one, relying on another sub-package test to do so first; under shuffle it ran first and nil-dereferenced gorm. Call initSubDB(t) so it is self-sufficient (empty DB yields an empty subDomain, so the subscriber-host fallback still holds).
- golangci goimports: gorm.io/gorm was grouped with the github.com/mhsanaei/3x-ui local imports in node_dirty_test.go. Move it into the third-party group.
* fix(settings): require server-side 2fa for sensitive changes
* fix(lint): group third-party imports separately from local (goimports)
golangci-lint goimports flagged setting.go and setting_security_test.go because xlzd/gotp and gorm.io/gorm were mixed into the github.com/mhsanaei/3x-ui local-prefix group. Move them into the third-party group so the local imports stand alone.
The external subscription fetcher read the remote body with a plain
io.LimitReader, silently truncating at 2 MiB and decoding whatever
prefix arrived (possibly a half share link). Detect the overflow with
the established N+1 pattern and return an error so the caller serves the
last cached value instead of a corrupted partial list.

* perf(xray): compile log/traffic regexps once at package scope
GetTraffic recompiled two stats regexps on every traffic tick, and LogWriter.Write
recompiled two more on every log line. Hoist all four to package-level vars so they
compile once at load instead of per call on hot paths.
* fix(xray): guard LogWriter.lastLine against the GetResult reader race
Write is driven by the Xray process goroutine while Process.GetResult
reads lastLine from the caller's goroutine, so the unsynchronized field
is a data race under `go test -race`. Add an RWMutex and route every
write through setLastLine; GetResult reads via LastLine().
* fix(xray): bound handler gRPC calls with a deadline
AddInbound, DelInbound and the AddUser AlterInbound call used
context.Background(), so a hung core connection could block the caller
indefinitely (for example while the process restart lock is held). Give
them a 10s deadline (handlerRPCTimeout) and a nil-client guard, matching
the other handler operations.
getSetting (WHERE key=?) runs on nearly every subscription request and job
tick and had no index, so each lookup full-scans the settings table past the
large xrayTemplateConfig blob. Add an index on settings.key; AutoMigrate
creates it on existing DBs too. Includes a HasIndex test.

NodeService.Delete dropped the node row (and its per-node child rows) without
checking for inbounds still referencing it via node_id, leaving orphaned
inbounds with a dangling node_id that confuse node sync, subscriptions and
cleanup. Refuse the delete with a clear error when inbounds are still attached,
and remove the per-node child rows before the node row inside one transaction.
Delete stays tolerant of a missing node row so it can still clean up orphaned
rows. Regression test covers the blocked and clean-delete paths.
The public subscription http.Server set no timeouts, leaving the most exposed
listener open to slow-header/Slowloris exhaustion. Mirror the panel server
timeouts already used in internal/web/web.go.
Remote node HTTP responses were read with an unbounded io.ReadAll, so a
broken or hostile node could force the master panel to buffer an arbitrarily
large body. The single Remote.do choke point that all node calls funnel
through now:
- validates the HTTP status before reading any success payload (a non-OK
body is only read up to a small bounded diagnostic snippet, so a node
cannot make the master buffer a large body just to return an error);
- fast-fails on an honestly-declared oversize Content-Length;
- reads the success body through readCappedBody, an io.LimitReader cap
(64 MiB) that rejects oversize with a typed error.
The 64 MiB cap bounds one response's wire/decompressed size; it is documented
as not a process-wide memory bound (endpoint-specific caps and a concurrency
budget remain follow-ups).
Tests cover the cap+1 boundary, an oversize streamed body, a normal envelope,
and non-OK status precedence.
A panic in a goroutine without a recover takes the whole panel down. The
per-node heartbeat and traffic-sync goroutines run remote network I/O for
each node with no panic isolation, so one misbehaving node could crash the
master.
Add common.GoRecover(name, fn), which runs fn in a goroutine guarded by a
recover that logs the panic with a stack trace instead of crashing, and use
it for the per-node heartbeat, traffic-sync and global-push goroutines. The
deferred WaitGroup/semaphore releases still run during panic unwind, so the
group never stalls. Other background goroutines can adopt the same helper.
The scheduler was created without a panic recovery wrapper, so a panic in any
scheduled job (traffic write, IP check, etc.) propagated up and could take down
the whole panel process. Wrap jobs with cron.Recover so a panic is logged and
the scheduler keeps running.
* fix(xray): verify the release archive checksum before installing
UpdateXray downloaded the Xray-core release zip and installed the binary
from it after only a TLS fetch, an HTTP-200 check and a size cap — the
archive itself was never verified, so a corrupted or tampered release
asset would be extracted and run as the panel's xray binary.
Verify the downloaded archive against the SHA2-256 published in the
release's .dgst sidecar (which XTLS ships next to every asset) before
installing, and abort the update on mismatch, a missing/short SHA2-256
entry, or an unreachable .dgst. The digest parser and fetch are covered by
tests, including the real .dgst line format ("SHA2-256= <hex>").
* address review: clearer warning + re-download guidance on checksum mismatch
Per review feedback on the PR: on a SHA-256 mismatch, surface a plain-language
warning that the downloaded archive is corrupted or differs from the official
release and that the user should exit and re-download, instead of a terse
"checksum mismatch" error. The install still aborts so a mismatched binary is
never run; the message now tells the user the safe next step.
The process cmd, done and exitErr fields were written by Start/startCommand and
the waitForCommand goroutine while IsRunning/GetErr/GetResult/Stop read them
concurrently from other goroutines (the status endpoint and the check-xray
job) — a data race. Guard them with a RWMutex: writers take the write lock;
readers snapshot under the read lock and run any blocking syscall
(Wait/Signal/Kill) on the local copy without holding it. IsRunning now uses the
done channel as the exit signal instead of reading cmd.ProcessState, which
races with cmd.Wait. Adds a -race regression test.
* fix(subscriptions): avoid shared mutable state during generation
* fix(subscriptions): serve external-link-only subs in JSON/Clash; load remark settings per request
The ForRequest refactor added an early `len(inbounds) == 0` return to
GetJson/GetClash that fired before external links were fetched, so a
subscription whose only entries are external links (or whose inbounds are
all disabled) rendered empty in the JSON and Clash formats. Drop the
premature check — the existing inbounds+externalLinks empty guard already
covers the truly-empty case.
Also load datepicker/emailInRemark in PrepareForRequest rather than only in
getSubs, so JSON and Clash remarks honor these settings instead of seeing
the zero values (emailInRemark previously depended on the shared-state leak
this PR fixes).
Add a regression test covering an external-link-only sub across both formats.

* feat(web): cap request body size on state-changing routes
* fix(web): exempt importDB from request body size cap
The 10 MiB body cap was applied globally, which would break database
restore (/panel/api/server/importDB) on any panel whose SQLite backup
exceeds the limit. Make MaxBodyBytes accept exempt path suffixes and
pass importDB through uncapped; the cap still covers all other
state-changing routes. Add a test for the skip-suffix behavior.
