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).
fix(bt): Fixed memory-safety and DoS defects in BR/EDR controller on ESP32-S31

Describe the base/layout/checks split and how to supply a custom LP-core layout
through the LINKER option, covering the usable-window symbols
(LP_CORE_USER_MEMORY_REGION_START / _END), the section-boundary macros
(LP_CORE_TEXT_START / TEXT_END / DATA_START / DATA_END), and minimal and
multi-region layout examples.
Add build-only host tests for LP-core custom linker layouts supplied through the
LINKER option. Cover the positive paths (a full-replacement layout, a
multi-region layout with a fixed-address section, a run-from-HP-mem layout, and
memory protection) and the link-time and configure-time checks (reset-vector
placement, sizing, shared-memory overrun, the MEMPROT RX/RW boundary, a missing
reset vector, and a missing LINKER script).
This file predates the adoption of ruff-format and was never reformatted,
because pre-commit only runs on the files touched by a change. GitHub PR
#18871 bumps the copyright year here, which pulls the file into the hook's
scope and makes check_pre_commit fail on a pre-existing formatting
violation unrelated to that change.

Disabled inquiry scan and page scan after SCO connection establishment
to reduce over-the-air bandwidth usage and improve audio quality by
prevent scan activities from interrupting SCO traffic.
The digest length and the condition that reserves it at the end of RTC RAM were
duplicated in seven places. Hold the reservation in a hidden Kconfig value that
is zero when the feature does not apply, so every consumer subtracts it
unconditionally, and derive ESP_SECURE_BOOT_DIGEST_LEN from it.
