  • Publication number: 20240104214
    Abstract: Systems and methods update firmware during authentication of a hardware component of an IHS (Information Handling System), where firmware updates are managed by a remote access controller that provides remote management of the IHS. The remote access controller calculates a measurement based on firmware loaded for use by a hardware component of the IHS. Based on the measurement, an integrity of the firmware loaded for use by the hardware component is validated against a reference signature. When the integrity of the firmware is not validated, the hardware component is quarantined. When the integrity of the firmware is successfully validated, the remote access controller determines whether a firmware update is required for the firmware loaded by the hardware component. When a firmware update is required, an integrity of the updated firmware is validated, the updated firmware is loaded by the hardware component and further initialization of the hardware component is allowed.

  • Publication number: 20240103830
    Abstract: In various embodiments, a remote access controller supporting remote management of an Information Handling System (IHS). The remote access controller receives a first firmware image comprising first firmware for a first hardware component of the IHS. A personality of the first firmware is determined and at least a portion of the first firmware is stored to a first region of a persistent storage of the first hardware component, where the first region is designated as storing firmware for adapting the first hardware component to the first personality. In response to a detected reconfiguration of the IHS, the remote access controller generates a notification of the first firmware that is stored by the first hardware component and that is usable to adapt operation of the first hardware component to the first personality.

  • Patent number: 11252138
    Abstract: A redundant key management system includes a key management system coupled to a plurality of server devices through a network. A first server device includes a managed device coupled to a first remote access controller device that receive a device locking key from the key management system and uses it to lock the managed device. The first remote access controller device then encrypts the device locking key, broadcasts the encrypted device locking key through the network to a second remote access controller device in a second server device, and erases the device locking key. Subsequently, the first remote access controller device transmits a request to retrieve the encrypted device locking key. When the first remote access controller receives the encrypted device locking key from the second remote access controller device, it decrypts the encrypted device locking key and uses the resulting device locking key to unlock the managed device.

  • Patent number: 10862900
    Abstract: Embodiments provide methods and systems for detecting rogue endpoints on a device management bus. A communications controller configured as a bus owner initiates discovery of managed devices coupled to the bus and generate a unique identifier for each managed device. The communications controller transmits a bus configuration message to the managed devices, including the respective unique identifiers. The managed devices are configured as bus endpoints based on the bus configuration message. The managed devices also capture the bus address of the communications controller from the received bus configuration message. Messages received by a managed device are authenticated as originating from the communications controller if the messages include the unique identifier provided to that managed device. The messages may be further authenticated by comparing the bus address of the message sender against the captured bus address of the communications controller.

  • Patent number: 10846159
    Abstract: Embodiments are described for operating a device management bus coupled to a remote access controller and a managed device. The remote access controller detects an inoperable state of the bus and determines a FRU (Field Replaceable Unit) memory is accessible on the managed device. A predefined reset indicator is written to the FRU memory. The managed device monitors for the reset indicator being written to a specified location in FRU memory. Upon detecting the reset indicator in FRU memory, the managed device resets a bus controller coupled to the device management bus and transmits a reset notification on the device management bus. The remote access controller may include an I2C shim that controls access to an I2C multiplexer utilized for transmitting I2C commands from a service processor and an I2C coprocessor, preventing certain inoperable bus states due to concurrent operation of the I2C multiplexer by the I2C coprocessor and the service processor.

  • Patent number: 10606784
    Abstract: Sideband device management bus messages are filtered using software operations in order to minimize dropped messages and to maintain the bus in an operable state. Redundant sideband device management buses are utilized in order to provide fail-over transmission of messages in scenarios where one of the buses becomes inoperable. Multi-packet messages are transmitted to managed devices via the sideband bus connections. If an inoperable state is detected in a sideband bus connection during transmission of a multi-packet message, the portion of the multi-packet message not received by the managed device is transmitted via a redundant sideband bus connection with the managed device. Software filtering of bus transactions utilizes a circular DMA buffer for storing all incoming transactions. Transactions of interest are copied to buffers associated with specific endpoints for processing.
