Abstract: An information handling system includes a network interface device coupled to a network, a memory including first code to instantiate an operating system including an exception handler and second code to instantiate an exception handler interface and a UNDI module, and a processor to execute the first code and the second code. The network interface device is responsive to a Universal Network Device Interface (UNDI) command. The operating system detects an exception and invokes the exception handler to write a stack frame associated with the exception to the memory in response to detecting the exception. The exception handler interface determines that the stack frame has been written in the memory and directs the UNDI module to provide the UNDI command to the network interface device to communicate the stack frame to the network.

Abstract: Systems and methods are provided that may be implemented to securely load Unified Extensible Firmware Interface (UEFI) images (e.g., UEFI Applications, UEFI Drivers, UEFI firmware volumes, etc.) onto an information handling system from an authenticated (e.g., OEM authenticated) hardware image source device or “IO store” (e.g., such as USB device, network file system device, PCIe device, network storage, shared storage, dynamic RAM disk, etc.) based on a UEFI virtual device path that is mapped to an authenticated hardware device path that is established for the authenticated hardware image source device.

Abstract: An information handling system includes a processor and a memory including code to implement a Unified Extensible Firmware Interface (UEFI). The UEFI includes a UEFI network file system module that provides a first compound command to get directory information for a first directory on a network storage device, provides a second compound command to get file information for the first directory, and provides a third compound command to open a file stored on the first directory. The UEFI also includes a UEFI network protocol module that sends the first compound command, the second compound command, and the third compound command to the network storage device, wherein the first compound command, the second compound command, and the third compound command are sent to the network storage device via a first network transaction.

Abstract: Systems and methods are provided that may be implemented to systems and methods that may be implemented to utilize direct memory access (DMA) remapping to control firmware updates and/or other configuration changes or device access control protocol for devices of an information handling system during the Unified Extensible Firmware Interface (UEFI) pre-boot phase before the booting the operating system (OS). The disclosed systems and methods may use DMA remapping during UEFI pre-boot to determine whether to allow or disallow pre-boot firmware updates and/or device configuration for hardware devices, and may be performed in the presence or absence of UEFI Secure Boot.

Abstract: Systems and methods are provided for updating hot-pluggable devices of an information handling system using dynamic EFI System Resource Table (ESRT) entries to implement an ESRT entry update procedure for hot-pluggable devices. Extended configuration space (e.g., such as PCIe Extended Config Space) of a hot-pluggable device may be utilized to store firmware update version information such as firmware version details, which is used in the OS space to update the ESRT table, and the system OS may read and apply the updated firmware version information and apply the firmware update immediately without additional OS reboots.

Abstract: An information handling system for enhanced system management mode (SMM) security may include a processor, system management random access memory (SMRAM), persistent memory, and basic input/output (BIOS) memory. The system may include instructions that, when loaded and executed by the processor, cause the processor to initialize the memory, initialize the BIOS memory, initialize the persistent memory, and check whether the system has previously executed a power-on self test (POST) routine. Based on a determination that the system has not previously executed a POST routine, the processor may unzip the SMM Code located in the BIOS memory store the unzipped SMM Code in the persistent memory and in the SMRAM. Based on a determination that the system has previously executed a POST routine, the processor may create a duplicate copy of the SMM Code from the persistent memory and store the duplicate copy in the SMRAM.

The method includes receiving, via a first processor of the client, a request to copy the first directory containing the first plurality of files from a first storage device to the target server. The first directory is parsed into a first i-node tree. Metadata corresponding to the first i-node tree is generated and transmit from the client to the target server. A second processor at the target server is triggered to generate a second directory based on the metadata corresponding to the first i-node tree. The first plurality of files contained in the first directory from the first storage device is transmitted to the target server.

Abstract: A first firmware volume of a Unified Extensible Firmware Interface (UEFI) compliant information handling system is accessed. Authentication information is retrieved from the first firmware volume using a UEFI Secure Architecture Protocol. Based on the authentication information, it is determined if the first firmware volume is a first type of firmware volume. If the first firmware volume is the first type of firmware volume, the first firmware volume is authenticated using the first authentication information and an authentication procedure other than Secure Boot authentication. If the first firmware volume is a second type of firmware volume, the second type different than the first type, the first firmware volume is authenticated using the first authentication information and the Secure Boot authentication.
