Jin Cheng 04ddb36756 fix(bt/bluedroid): moved L2CAP length check into start packets only 2026-04-08 20:41:42 +08:00
Jon Gilmore 02b5d4bb13 fix(bt/bluedroid): fix ACL reassembly dropping valid continuation fragments 
The minimum length check in `reassemble_and_dispatch()` applied the START packet minimum (`HCI_ACL_PREAMBLE_SIZE + L2CAP_LENGTH_SIZE` = 8 bytes) to **all** ACL packets, including continuation fragments. Continuation fragments only carry the 4-byte ACL preamble (handle + length) with no L2CAP header, so small but valid continuations (5-7 bytes) were incorrectly rejected as "too short."

This caused the first L2CAP PDU in a rapid burst of BLE GATT indications to be silently dropped. The partial reassembly was orphaned, then discarded when the next indication's START fragment arrived, producing:

```
E BT_HCI: ACL packet too short (len=5)
W BT_HCI: reassemble_and_dispatch found unfinished packet for handle with start packet. Dropping old.
```

Parse the ACL preamble first (requires only 4 bytes) to determine the boundary flag, then apply the L2CAP length check only to START packets. Continuation packets are now accepted with the correct minimum of `HCI_ACL_PREAMBLE_SIZE` (4 bytes).

- ESP32-S3 connected to a BLE peripheral that fragments indications at 40 bytes per L2CAP PDU
- Peripheral sends 8+ indications within ~200ms (burst of state changes)
- The final continuation fragment of the first indication is small (5-6 bytes after type stripping)
- 100% reproducible on every burst; confirmed on ESP-IDF 5.5.3, 5.5.4, and 6.0.0

Verified on ESP32-S3 with a Sub-Zero wall oven (SO3050PESP, firmware 8.5):
- **Before fix:** First indication in every burst lost (ACL reassembly failure)
- **After fix:** All indications in burst delivered correctly, including when the final continuation fragment is 5-6 bytes

Ashish Sharma e08f079ce3 feat(http_server): adds example to test server pong response 2026-03-16 16:56:13 +08:00
Peter Backeris 3d0e26170d fix(esp_http_server): Dispatch PONG frames to WebSocket handler 
PONG frames (opcode 0xA) were never dispatched to the user's WebSocket
handler despite an existing comment stating they should be. The dispatch
condition `ra->ws_type < HTTPD_WS_TYPE_CLOSE` excluded PONG (0xA)
since CLOSE is 0x8.

This caused a critical secondary bug: when the server sends PING frames
and the client responds with PONG, httpd_ws_recv_frame() is never
called for the PONG, leaving the remaining frame bytes (second_byte
plus 4-byte mask_key) unconsumed in the TCP buffer. On the next
WebSocket read, these orphaned bytes are misinterpreted as a new frame
header, causing either "WS frame is not properly masked" errors or
EAGAIN timeouts with garbage length values, effectively destroying
the connection.

Add `ra->ws_type == HTTPD_WS_TYPE_PONG` to the dispatch condition so
PONG frames reach the user handler, which calls httpd_ws_recv_frame()
to properly consume the frame bytes from the socket.
