- Gate bta_sys_event() on both 'is_reg' and 'reg[id]' to prevent
stale event delivery.
- Defer bta_sys_deregister() to the end of profile disable handlers
to ensure pending DISABLE events are processed.
- Add disabling flag to HFP AG for tracking asynchronous teardown.
Sort bond entries by bond_count after in-place updates to maintain correct
eviction order, and log IRK resolving-list failures instead of failing the bond.
AVDT:
- Roll back CCB allocation when cmd/rsp queue creation fails
- Free media packet on invalid handle in AVDT_WriteReqOpt
- Zero-init timeout failure message before GETCAP callback
- Initialize lcid_tbl to 0xFF to avoid mapping to tc_tbl[0]
BTA/AVRCP:
- Use size_t for AVRC message copy buffer allocation
- Allocate before register in BTA_AvEnable
- Guard BTA_AvRegister callback when enable never completed
- Remove invalid free of inline Cover Art image_descriptor
A2DP BTC/API:
- Default g_a2dp_on_deinit to true before profile init
- Reject source audio send when A2DP is deiniting
- Add shutdown state check in btc_a2dp_sink_shutdown
- Guard A2DP source timer against freed dynamic local param
- Add sdp_seq to avoid p_ccb being free during sdp
- Changed some BTA_Pba functions to return non-void value
- Improve error catching and report
- Refactor bta_pba_client_response to avoid UAF problem
- Rearrange btc_pba_client init flag to avoid some disturbing bug
bt_mesh_bta_gatts_cb did not always answer ATT Read/Write Requests:
- READ: on a callback error it only logged a warning and sent nothing; a
0-byte read (Read Blob at an offset equal to the value length) also sent
nothing, although it is a successful empty read.
- WRITE: on a callback error it sent nothing, and a partial/zero write was
treated as success.
- Both: when the handle was not found or the attribute had no read/write
callback, the request was silently dropped.
An ATT Request must always be answered:
- READ: len >= 0 is success -> Read Response (a 0-byte read yields an empty
value); len < 0 -> ATT Error Response carrying the callback's error code
(-len, since BLE_MESH_GATT_ERR(x) == -x). The copy length is clamped to
the source buffer size as a defensive bound. If the handle is unknown or
the attribute has no read callback, respond with INVALID_HANDLE /
READ_NOT_PERMITTED.
- WRITE: when need_rsp is set, always reply. len == write length -> Write
Response; otherwise (negative ATT error, partial write, or 0) -> ATT
Error Response (the negative code, or UNLIKELY for partial/0). If the
handle is unknown or the attribute has no write callback, respond with
INVALID_HANDLE / WRITE_NOT_PERMITTED. Write Without Response still sends
no response.
A non-success status passed to BTA_GATTS_SendRsp is turned into an ATT
Error Response by the GATT layer (gatt_sr_process_app_rsp ->
gatt_send_error_rsp).
