feat(pubsub): persistent validation and diagnostic commands (#11110)
* feat(pubsub): persistent seqno validation and diagnostic commands - upgrade go-libp2p-pubsub to v0.15.0 - add persistent seqno validator using BasicSeqnoValidator stores max seen seqno per peer at /pubsub/seqno/<peerid> survives daemon restarts, addresses message cycling in large networks (#9665) - add `ipfs pubsub reset` command to clear validator state - add `ipfs diag datastore get/count` commands for datastore inspection requires daemon to be stopped, useful for debugging - change pubsub status from Deprecated to Experimental - add CLI tests for pubsub and diag datastore commands - remove flaky pubsub_msg_seen_cache_test.go (replaced by CLI tests) * fix(pubsub): improve reset command and add deprecation warnings - use batched delete for efficient bulk reset - check key existence before reporting deleted count - sync datastore after deletions to ensure persistence - show "no validator state found" when resetting non-existent peer - log deprecation warnings when using --enable-pubsub-experiment or --enable-namesys-pubsub CLI flags * refactor(test): add datastore helpers to test harness --------- Co-authored-by: Andrew Gillis <11790789+gammazero@users.noreply.github.com>

+#### Improved IPNS over PubSub validation
55
+
56
+[IPNS over PubSub](https://specs.ipfs.tech/ipns/ipns-pubsub-router/) implementation in Kubo is now more reliable. Duplicate messages are rejected even in large networks where messages may cycle back after the in-memory cache expires.
57
+
58
+Kubo now persists the maximum seen sequence number per peer to the datastore ([go-libp2p-pubsub#BasicSeqnoValidator](https://pkg.go.dev/github.com/libp2p/go-libp2p-pubsub#BasicSeqnoValidator)), providing stronger duplicate detection that survives node restarts. This addresses message flooding issues reported in [#9665](https://github.com/ipfs/kubo/issues/9665).
59
+
60
+Kubo's pubsub is optimized for IPNS use case. For custom pubsub applications requiring different validation logic, use [go-libp2p-pubsub](https://github.com/libp2p/go-libp2p-pubsub) directly in a dedicated binary.
61
+
62
+#### New `ipfs diag datastore` commands
63
+
64
+New experimental commands for low-level datastore inspection:
65
+
66
+- `ipfs diag datastore get <key>` - Read raw value at a datastore key (use `--hex` for hex dump)
67
+- `ipfs diag datastore count <prefix>` - Count entries matching a datastore prefix
68
+
69
+The daemon must not be running when using these commands. Run `ipfs diag datastore --help` for usage examples.
70
+
71
#### 🚇 Improved `ipfs p2p` tunnels with foreground mode
72
73
P2P tunnels can now run like SSH port forwarding: start a tunnel, use it, and it cleans up automatically when you're done.

-### `Pubsub.Enabled`
2418
+The `ipfs pubsub` commands can also be used for basic publish/subscribe
2419
+operations, but only if Kubo's built-in message validation (described below) is
2420
+acceptable for your use case.
2421
+
2422
+### When to use a dedicated pubsub node
2423
+
2424
+Kubo's pubsub is optimized for IPNS. It uses opinionated message validation
2425
+that may not fit all applications. If you need custom Message ID computation,
2426
+different deduplication logic, or validation rules beyond what Kubo provides,
2427
+consider building a dedicated pubsub node using
2428
+[go-libp2p-pubsub](https://github.com/libp2p/go-libp2p-pubsub) directly.
2429
+
2430
+### Message deduplication
2431
+
2432
+Kubo uses two layers of message deduplication to handle duplicate messages that
2433
+may arrive via different network paths:
2434
+
2435
+**Layer 1: In-memory TimeCache (Message ID)**
2436
+
2437
+When a message arrives, Kubo computes its Message ID (hash of the message
2438
+content) and checks an in-memory cache. If the ID was seen recently, the
2439
+message is dropped. This cache is controlled by:
2440
+
2441
+- [`Pubsub.SeenMessagesTTL`](#pubsubseenmessagesttl) - how long Message IDs are remembered (default: 120s)
2442
+- [`Pubsub.SeenMessagesStrategy`](#pubsubseenmessagesstrategy) - whether TTL resets on each sighting
2443
+
2444
+This cache is fast but limited: it only works within the TTL window and is
2445
+cleared on node restart.
2446
2416
-**DEPRECATED**: See [#9717](https://github.com/ipfs/kubo/issues/9717)
2447
+**Layer 2: Persistent Seqno Validator (per-peer)**
2448
+
2449
+For stronger deduplication, Kubo tracks the maximum sequence number seen from
2450
+each peer and persists it to the datastore. Messages with sequence numbers
2451
+lower than the recorded maximum are rejected. This prevents replay attacks and
2452
+handles message cycles in large networks where messages may take longer than
2453
+the TimeCache TTL to propagate.
2454
+
2455
+This layer survives node restarts. The state can be inspected or cleared using
2456
+`ipfs pubsub reset` (for testing/recovery only).
