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
A2DP BTC/API:
- Default g_a2dp_on_deinit to true before profile init
- Add shutdown state check in btc_a2dp_sink_shutdown
- Guard A2DP source timer against freed dynamic local param
- advance connect queue on synchronous connect_cb failure
- lock bta_alarm_hash_map in all BTA timer APIs
- free controller params after stack disable; cleanup on init fail
- handle BTE_InitStack failure and signal init future
- validate HCI remote name event length before parse
- drop stale L2CAP quick-timer alarm events
- Fix connection failure when using RPA with whitelist filtering
- Fix disconnect with reason 0x08 during full scan
- Fix peer RPA resolution failure when advertising with a local identity address
Return BTM_HCI_ERROR | hci_status from legacy BLE 4.2 GAP HCI command
paths instead of mapping failures to BTM_ILLEGAL_VALUE or
BTM_NO_RESOURCES. Add btm_ble_status_from_hci() helper and propagate
real status through scan start/stop completion callbacks.

Read By Type Response Length is one octet (max 255). When MTU was
large enough to return a long characteristic value in one pair, the
server wrote (UINT8)(value_len + 2) and overflowed (e.g. 513 -> 1),
so the client rejected the PDU as GATT_INVALID_PDU (0x04).
Cap server value to 253 bytes per pair, clamp the length byte, and
continue long reads via Read Blob when the capped size is returned.

Skip prepare-write echo validation when the GATT stack reports a
non-success status. ATT Error Response carries no prepare-write echo
body (rsp_len=0), so the check incorrectly overwrote errors such as
GATT_INSUF_AUTHENTICATION (0x05) with GATT_INVALID_PDU (0x04).

Release the BLE sync semaphore and record HCI status when a
synchronous command is rejected via Command Status, since no
Command Complete event follows.

When service change cancels in-progress discovery, bta_gattc_disc_cmpl()
re-triggers discovery without marking auto_update as REQ_WAITING. If a
client command is queued in p_q_cmd, bta_gattc_start_discover() refuses
to restart and the command is never dispatched.

Route unknown BD_ADDR and other immediate failures through the existing
need_cb path so ESP_GAP_BLE_UPDATE_CONN_PARAMS_EVT is always delivered.

Include client_if, handle, bd_addr, and server cache state in the
warning logged when notification registration skips handle validation.

Do not rewrite static or non-resolvable random peer addresses to
identity type 0x03 when CONFIG_BT_BLE_RPA_SUPPORTED is enabled.

HFP AG:
- Fix mSBC EV3 second-packet payload length calculation to prevent OOB read and infinite loop
- Add init/deinit guards in HF AG helper functions to avoid NULL deref
- Break SCO CI data loop when SCO is not open to prevent CPU starvation
- Guard BTM_FreeSCN(0) and reset SCN after free in bta_ag_del_records
- Use OI_UINT32 for mSBC decode frame length to avoid stack corruption
- Bound AT Dial command string copy to BTA_AG_AT_MAX_LEN
HFP Client:
- Use OI_UINT32 for mSBC decode frame length to avoid stack corruption
- Free SDP db, collision/AT timers and queued AT cmds before scb reset on disable
- Fix mSBC EV3 second-packet payload length calculation (same as AG)
- Reject pcm_resample input smaller than overlap window (96 bytes) on filtered path
- Break SCO CI data loop when SCO is not open to prevent CPU starvation
- Guard BTM_FreeSCN(0) and reset SCN after free in bta_hf_client_del_record
Peers may report custom or non-standard codec UUIDs in AT+BAC alongside
CVSD/mSBC. Returning BTA_AG_CODEC_NONE on the first unknown entry
discarded already-parsed standard codecs. Log unknown UUIDs and continue
parsing so negotiated capabilities still reflect supported codecs.
