oemcommands: check for non-printable characters in biosID

Issue: sdbusplus throws exception and core dumped when non ascii
characters are present in biosID.

Fix: check for non printable characters in biosID string and return
Invalid data field in request response.

Tested:
Command: ipmitool raw 0x30 0x26 0x1 0xAF
Response: Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0
cmd=0x26 rsp=0xcc): Invalid data field in request

Command: ipmitool raw 0x30 0x26 0x1 0x09
Response: Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0
cmd=0x26 rsp=0xcc): Invalid data field in request

Command: ipmitool raw 0x30 0x26 0x1 0x1F
Response: Unable to send RAW command (channel=0x0 netfn=0x30 lun=0x0
cmd=0x26 rsp=0xcc): Invalid data field in request

Command: ipmitool raw 0x30 0x26 0x1 0x20
Response: 01

Command: ipmitool raw 0x30 0x26 0x1 0x43

Intel IPMI OEM support library

This component is intended to provide Intel-specific IPMI[3] command handlers for OpenBMC. These handlers are intended to integrate BMC with servers based on Intel architecture.

Overview

intel-ipmi-oem serves as an extension[1] to OpenBMC IPMI daemon[2]. It is compiled as a shared library and intended to both:

  • override existing implementation of standard IPMI commands to comply with Intel-specific solutions,
  • provide implementation for non-standard OEM extensions.

Capabilities

Related features provided by the library are grouped in separate source files. Main extensions to vanilla OpenBMC IPMI stack are the following:

  • Acquiring SMBIOS data over IPMI
  • Commands for better integration with Intel hardware
  • Firmware update extensions
  • Extended parsing of IPMI Platform Events[4]
