 This folder contains a skeleton audio control HAL implementation in Rust to

 audio control HAL, include

 This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
 and does not pass VTS/CTS. Vendor must replace the logic in

+     * 5G TS 38.331 cipheringDisabled and integrityProtection
+     * ======================================================
+     * For most connections, generally what is reported by the network is what ends up being used.
+     * There are two significant cases where this may not be the case. In 5G, per the introduction
+     * of network configuration options cipheringDisabled and integrityProtection (TS 38.331), the
+     * network can have declared certain security algorithms to be used while also requiring a null
+     * algorithm via those parameters.
+     *
+     *
+     * Exceptions for DRBs with null integrity (pre-5G Rel 16)
+     * =======================================================
+     * When reporting the SecurityAlgorithm for a ConnectionType which includes a DRB, there is an
+     * exception where a DRB with null integrity is not to be considered/included in reporting
+     * except for 5G Rel 16 connections and newer. Because DRBs almost always use null integrity in
+     * practice, and thus if included the report would always be null, rendering the report
+     * useless. For anything 5G Rel 16 or newer, accurate reporting for the DRB's integrity is
+     * required.
+     *
+     *
+     * NRDC MCG and SCGs
+     * =================
+     * In the NRDC case, there can be two sets of algorithms, one for the MCG (Master Cell Group)
+     * and one for the SCG (Secondary Cell Group). In this case, always send a combined update that
+     * reflects the weaker of the algorithms, e.g. (weakest) NEA0 < NEA1 < NEA2 < NEA3 (strongest).
+     * This applies to both the ciphering and integrity algorithms.
+     *
+     *
+     * Determining the value of isUnprotectedEmergency
+     * ===============================================
+     * 2G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * 3G: isUnprotectedEmergency is true if the ciphering and integrity algorithm are NULL.
+     * 4G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * 5G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * Notes:
+     *    - On integrity: In 4G, PDCP can be LTE-based or NR-based. Starting from 5G Rel 17, only
+     *      the NR-based PDCP supports DRB integrity. As the PDCP version can change during a DRB's
+     *      operation, it becomes complicated when integrity is used to determine whether an
+     *      emergency call is protected or not, hence its exclusion to simplify implementation.
+     *    - 4G and 5G with multiple DRBs : emergency calls are protected under that RAT only if all
+     *      DRBs are protected (including IMS DRB).
+     *    - 4G and 5G DRB integrity: Since DRB integrity is not enabled in most networks, if both
+     *      ciphering and integrity are taken into account to determine the value of
+     *      isUnprotectedEmergency, the value will mostly be false, hence why it is excluded.

+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.
