Select nodes had this flag enabled, testing by the community
and hardware specs indicate this can be enabled global for all
node types using this chipset.
Any nodes down the line that may be quirky can be individually
disabled with `-U USE_CC310_HW_CRYPTO`.
First upstream merge since the 2026-06-06 base (191 upstream commits). 14 files
conflicted; resolutions below.
Fleet-critical check (Constraint 1): upstream reordered NodePrefs members
(rx_boosted_gain / path_hash_mode moved to the struct tail) but did NOT change
/com_prefs. Persistence is written field-by-field at explicit offsets, so member
order is in-memory only. Verified the fork's writeCommonPrefsImage() is
byte-identical to upstream's inline writer at every offset (79 pad, 121, 122,
290-294). No migration needed.
Resolutions:
- CommonCLI.h: kept the fork's NodePrefs (superset) and adopted upstream's
setRxBoostedGain(bool)->bool signature change, which CommonCLI.cpp now uses to
report unsupported. Corrected a stale comment claiming rx_boosted_gain lives at
offset 79 (it is a pad; the field is at 290).
- CommonCLI.cpp: kept the fork's legacy /com_prefs migration and the extracted
writeCommonPrefsImage() call.
- UITask.cpp: three-way merge - upstream's drawTextCentered + powering-off
screen, plus the fork's WITH_WEBCONFIG portal/reboot screens.
- ESP32Board.cpp, MeshCore.h, platformio.ini: kept both sides (fork OTA additions
alongside upstream powerOff/enterDeepSleep and Packet.cpp).
- MicroNMEALocationProvider.h: took upstream's claim/release and added the
_claims member they depend on.
- MyMesh.cpp/.h (repeater + room server): kept the fork's superset defaults.
- Removed duplicate declarations auto-merge produced: RadioLibWrapper::_cad_enabled
and MyMesh::getCADEnabled().
Verification: native suite 15/15 (incl. upstream's new test_mesh_tables), both
MQTT smoke builds green, ArduinoJson pin check passes. Hardware validation next.
Replace direct JSON construction in MQTTMessageBuilder with calls to
MQTTPayloadBuilder for building status, packet, and raw messages.
This change improves code maintainability and reduces duplication by
centralizing message formatting logic. Additionally, update platformio.ini
to include ArduinoJson dependency for JSON handling.
The new test_kiss_modem suite needs KissModem headers and sources that
only native_kiss_modem provides. Scope native to test_utils and run both
envs in the unit test workflow.
Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
Include detailed instructions for local testing of observer and WiFi
functionality without hardware. Document the use of a mock backend and
Wokwi ESP32-S3 simulation for easier development and testing.
Enhance the MQTT implementation documentation to improve developer
experience and facilitate testing workflows.
The precompiled IDF 4.4 WebSocket transport (libtcp_transport.a) has an
off-by-one in ws_connect(): when a wss:// endpoint answers the upgrade
request with >=1024 bytes of HTTP response before the blank-line
terminator (typical of a down broker behind a proxy serving a large
error page), it writes a NUL one byte past the 1024-byte ws->buffer.
Heap poisoning catches the clobbered tail canary (0xbaad5678 ->
0xbaad5600) only when the block is freed in ws_destroy() during
esp_mqtt_client_destroy() - i.e. MQTTBridge::end() - so a single down
broker made every deferred 'ota update' panic and reboot at teardown,
before the download started. Decoded from a Heltec V3 crash backtrace
on v1.16.0.11; line numbers match ESP-IDF release/v4.4 exactly.
The transport code ships precompiled, so patch at link time instead:
[esp32_base] wraps esp_transport_ws_init and the wrapper swaps the
fresh buffer for a (WS_BUFFER_SIZE + 1)-byte allocation, making the
out-of-bounds index land on owned memory. The oversized handshake then
fails cleanly instead of corrupting the heap. Pass-through on IDF 5.x,
where upstream already fixed it; delete with the Arduino core 3.x move.
Verified: wrap resolves from ESP32WsTransportFix.cpp.o in the observer
firmware.map; observer, room-server observer and plain repeater ESP32
targets build. RAK_4631_repeater failure is pre-existing (reproduced
on the merge base without these changes).
hasSeen() was simultaneously a predicate and a mutator — it inserted the
packet hash on every miss, making five call sites that only wanted to mark
a packet as sent call it with the return value discarded.
Split into:
- wasSeen() — pure predicate, no side effects
- markSeen() — explicit insert
All query sites now call markSeen() immediately after wasSeen() returns
false, preserving identical runtime behaviour. The five mark-only send
sites (sendFlood, sendDirect, sendZeroHop x2) now call markSeen directly.
Also fixes three bridge sites (BridgeBase, ESPNowBridge, RS232Bridge)
that had the same query+implicit-insert pattern.
Tests: add test/test_mesh_tables/ covering wasSeen purity, markSeen,
dup stats, and clear. Update SHA256 mock to produce deterministic output
(previously finalize() was a no-op). Add Packet.cpp to native build filter.
