Description

Technical Field

[0001] This invention relates to the field of solid-state drive MCTP communication and storage technology, and in particular to an SSD MCTP control message verification method, apparatus, computer equipment, and storage medium based on SMBUS. Background Technology

[0002] MCTP (Management Component Transport Protocol) defines a communication model for communication between elements of the platform management subsystem in a computer system. It facilitates communication between management controls and other management controls or managed devices. It can be used on various bus types, such as SMBUS (System Management Bus) and PCIe Bus (Peripheral Component Interconnect Express Bus). In computers without a host operating system or with a faulty operating system, managed devices within the computer, such as solid-state drives (SSDs), can be accessed out-of-band using the MCTP protocol through the BMC (Baseboard Management Controller) on the motherboard. In the NVME-MI (Non-Volatile Memory Express-Management Interface) specification, MCTP resides in the transport layer. When a solid-state drive (SSD) supporting MCTP performs out-of-band management access, the BMC assembles the commands to be sent into MI messages according to the NVME-MI protocol specification, encapsulates them into MCTP messages through the MCTP transport layer, and sends the MCTP messages to the SSD via the SMBUS link. After receiving the MCTP messages, the SSD decapsulates them to obtain the MI messages, parses the MI messages to obtain the message to be sent, and then assembles the data to be replied into MI messages according to the MI protocol specification. The reply MI messages are then encapsulated into MCTP messages through the MCTP transport layer and sent to the BMC via the SMBUS link. The BMC parses the MCTP messages and then parses the MI messages to obtain the reply messages.

[0003] Therefore, it is crucial to test the MCTP control message commands of solid-state drives (SSDs) that support the MCTP transport protocol. If the host cannot obtain the terminal ID via the MCTP control command Get EID (Endpoint ID) or cannot assign the correct MCTP terminal ID via the MCTP control command Set EID, commands sent from the BMC will fail to reach the SSD via SMBUS to retrieve information from the SSD or execute commands, which will affect the subsequent NVMe-MI functionality.

[0004] Currently, most laptops and desktops with SSD interfaces do not support MCTP over SMBUS testing. ULINK's Driver Master software and its accompanying PSPA (PCIe SSD Power Adapter, hereinafter referred to as PSPA) hardware lack physical SMBUS traces, and the relevant MCTP testing interfaces have not yet been developed. Therefore, there is an urgent need to develop an SMBUS-based SSD MCTP control message verification method. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an SSD MCTP control message verification method, apparatus, computer equipment, and storage medium based on SMBUS.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] Firstly, this embodiment provides an SSD MCTP control message verification method based on SMBUS, including the following steps:

[0008] Start SMBUS on the SSD;

[0009] A new address, 3Ah, is assigned via SMBUS ARP;

[0010] Send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0011] Retrieve the destination EID value from the MCTP over SMBUS Get EID command;

[0012] Determine if the destination EID value is equal to the default value;

[0013] If the destination EID value is equal to the default value, then send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=0, EOM=1, TO=1;

[0014] Determine whether the command should be discarded;

[0015] If the command is discarded, then send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=0;

[0016] Determine whether the command should be discarded;

[0017] If the command is discarded, then send an MCTP over SMBUS Get EID command to the destination EID at address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0018] Determine whether the command should be discarded;

[0019] If the command is discarded, then send an MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1, header=2;

[0020] Determine whether the command should be discarded;

[0021] If the command is dropped, an MCTP over SMBUS Get EID command is sent to address 3Ah, i.e., SOM=1, EOM=1, TO=1, setting the destination EID to a non-specially defined EID, i.e., setting the destination EID;

[0022] Send the MCTP over SMBUS Get EID command again to the destination at address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0023] Get the destination setting EID value;

[0024] Determine if the destination's EID value is equal to the set value;

[0025] If the destination EID value is equal to the set value, the verification is successful.

[0026] The further technical solution is as follows: In the step of allocating a new address, i.e., address 3Ah, through SMBUS ARP, the default address D4 of the device is changed to a new address, i.e., 3Ah, which is not D4h or C2h, through the SMBUS ARP address allocation command.

[0027] The further technical solution is as follows: after the step of determining whether the value of the destination EID is equal to the default value, it also includes: if the value of the destination EID is not equal to the default value, then the destination EID has been successfully configured.

[0028] The further technical solution is as follows: after the step of determining whether the value of the destination EID is equal to the set value, it also includes: if the value of the destination EID is not equal to the set value, then the destination EID setting fails.

[0029] Secondly, this embodiment provides an SSD MCTP control message verification device based on SMBUS, including: a startup unit, an allocation unit, a first sending unit, a first acquisition unit, a first judgment unit, a second sending unit, a second judgment unit, a third sending unit, a third judgment unit, a fourth sending unit, a fourth judgment unit, a fifth sending unit, a fifth judgment unit, a sending setting unit, a sixth sending unit, a second acquisition unit, a sixth judgment unit, and a verification unit.

[0030] The boot unit is used to boot the SMBUS on the SSD;

[0031] The allocation unit is used to allocate a new address, namely address 3Ah, via SMBUS ARP;

[0032] The first sending unit is used to send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0033] The first acquisition unit is used to acquire the value of the destination EID in the MCTP over SMBUS Get EID command;

[0034] The first determination unit is used to determine whether the value of the destination EID is equal to the default value;

[0035] The second sending unit is used to send an MCTPover SMBUS Get EID command to address 3Ah if the value of the destination EID is equal to the default value, i.e., SOM=0, EOM=1, TO=1;

[0036] The second judgment unit is used to determine whether the command should be discarded;

[0037] The third sending unit is used to send an MCTP over SMBUS GetEID command to address 3Ah if the command is dropped, i.e., SOM=1, EOM=1, TO=0;

[0038] The third judgment unit is used to determine whether the command should be discarded;

[0039] The fourth sending unit is used to send an MCTPover SMBUS Get EID command to the destination EID at address 3Ah if the command is dropped, i.e., SOM=1, EOM=1, TO=1;

[0040] The fourth judgment unit is used to determine whether the command should be discarded;

[0041] The fifth sending unit is used to send an MCTP over SMBUS GetEID command to address 3Ah if the command is dropped, i.e., SOM=1, EOM=1, TO=1, header=2;

[0042] The fifth judgment unit is used to determine whether the command should be discarded;

[0043] The sending setting unit is used to send an MCTP over SMBUS GetEID command to address 3Ah if the command is dropped, i.e., SOM=1, EOM=1, TO=1, to set the destination EID to a non-specially defined EID, i.e., the destination setting EID;

[0044] The sixth sending unit is used to send the MCTP over SMBUSGet EID command again to the destination set EID at address 3Ah, that is, SOM=1, EOM=1, TO=1;

[0045] The second acquisition unit is used to acquire the value of the destination setting EID;

[0046] The sixth judgment unit is used to determine whether the value of the destination EID is equal to the set value;

[0047] The verification unit is configured to verify successfully if the value of the destination EID is equal to the set value.

[0048] The further technical solution is as follows: In the allocation unit, the default address D4 of the device is changed to a new address other than D4h or C2h, namely 3Ah, by means of the SMBUS ARP address allocation command.

[0049] The further technical solution includes: a default unit, which is used to indicate that the destination EID has been successfully configured if the value of the destination EID is not equal to the default value.

[0050] The further technical solution includes: a failure unit, used to fail to set the destination EID if the value of the destination EID is not equal to the set value.

[0051] Thirdly, this embodiment provides a computer device, which includes a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, it implements the SMBUS-based SSD MCTP control message verification method as described above.

[0052] Fourthly, this embodiment provides a storage medium storing a computer program, the computer program including program instructions, which, when executed by a processor, can implement the SMBUS-based SSD MCTP control message verification method as described above.

[0053] The advantages of this invention compared to existing technologies are: it can quickly and efficiently verify whether MCTP control message commands can reach the solid-state drive normally through the SMBUS link, and send the data to be replied back to the BMC through the MCTP transmission protocol. By verifying the EID, different EIDs can be set to avoid conflicts in communication with the same address.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0063] Specifically, this SMBUS-based SSD MCTP control message verification method requires the following:

[0064] Hardware requirements:

[0065] Computer under test: SANBLAZE RM4 server;

[0066] Note: The test computer should support servers that support SMBUS and MCTP transmission protocols; the specific model is not mandatory. A SANBLAZE RM4 server is preferred as the test computer.

[0067] The solid-state drive under test: an M.2 solid-state drive that supports SMBUS ARP and MCTP transmission protocols;

[0068] Software requirements:

[0069] Operating system: CentOS 10.464bit;

[0070] Testing tools: sb_i2c, mi, io;

[0071] Test script: A self-written Shell test script.

[0072] Specifically, ARP (Address Resolution Protocol) is a TCP / IP protocol that obtains the physical address based on the IP address. When a host sends information, it broadcasts an ARP request containing the target IP address to all hosts on the local area network and receives a response message to determine the target's physical address. After receiving the response message, the IP address and physical address are stored in the local ARP cache and retained for a certain period of time. Subsequent requests directly query the ARP cache to save resources. The Address Resolution Protocol is based on mutual trust among hosts on the network. Hosts on the local area network can send ARP reply messages independently. When other hosts receive a reply message, they do not check the authenticity of the message but simply record it in their local ARP cache. Therefore, an attacker can send a fake ARP reply message to a host, causing the message to fail to reach the intended host or reach the wrong host.

[0073] Please see Figure 1 The specific embodiment shown in this invention discloses an SSD MCTP control message verification method based on SMBUS, comprising the following steps:

[0074] S1, start SMBUS on SSD;

[0075] S2, allocates a new address, namely address 3Ah, via SMBUS ARP;

[0076] Specifically, the default address D4 (the address dedicated to basic management commands) of the device is changed to a new address other than D4h or C2h, namely 3Ah, through the SMBUS ARP address allocation command.

[0077] S3 sends an MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0078] Specifically, the MCTP over SMBUS Get EID command is sent to address 3Ah via the NVME-MI application interface (SOM (Start Of Message, hereinafter referred to as SOM) = 1; EOM (End Of Message, hereinafter referred to as EOM) = 1; TO (Tag Owner, hereinafter referred to as TO) = 1).

[0079] S4, retrieve the destination EID value from the MCTP over SMBUS Get EID command;

[0080] Specifically, the EID value is obtained by sending the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1.

[0081] S5, determine whether the value of the destination EID is equal to the default value; if the value of the destination EID is not equal to the default value, then the destination EID has been successfully configured and can be used as the access ID of the target device, or it can be reconfigured to a specified EID.

[0082] Specifically, the default value is 00, indicating that no MCTP EID has been assigned.

[0083] S6. If the value of the destination EID is equal to the default value, then send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=0, EOM=1, TO=1;

[0084] Specifically, an MCTP over SMBUS Get EID command is sent to address 3Ah via NVME-MI, with SOM=0, EOM=1, and TO=1. Since SOM=0, it means that the first data of this MCTP command will not start, thus causing the command to be discarded due to an error.

[0085] S7, determine whether the command should be discarded; if the command is not discarded, handle the SOM=0 exception and display a message box indicating that the firmware cannot discard invalid commands when SOM=0.

[0086] S8, if the command is discarded, then send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=0;

[0087] Specifically, an MCTP over SMBUS Get EID command is sent to address 3Ah via NVME-MI, with SOM=1, EOM=1, and TO=0. Since TO=0, it indicates that the MCTP command is not a data packet initiated by the main management control and not responded to by the management control, thus causing the command to be dropped due to an error.

[0088] S9, determine whether the command is discarded; if the command is not discarded, handle the exception of TO=0, and the prompt box indicates that the firmware cannot discard invalid commands when TO=0.

[0089] S10, if the command is discarded, then send the MCTP over SMBUS Get EID command to the destination EID at address 3Ah, i.e., SOM=1, EOM=1, TO=1;

[0090] Specifically, an MCTP over SMBUS Get EID command was sent to the destination EID at address 3Ah via NVME-MI. Since the destination EID had never been assigned, the invalid destination EID caused the command to fail and be discarded.

[0091] S11, determine whether the command is discarded; if the command is not discarded, handle the unassigned destination EID exception, and the prompt box indicates that the firmware cannot discard commands with unassigned destination EIDs.

[0092] S12, if the command is discarded, then send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1, header=2;

[0093] Specifically, an MCTP over SMBUS Get EID command is sent to address 3Ah via NVME-MI, with the header version set to 2. Since over SMBUS requires a header version of 1, the mismatched media causes the command to fail and be discarded.

[0094] S13, determine whether the command should be discarded; if the command is not discarded, handle the header error and display a message box indicating that the firmware cannot discard commands containing mismatched media.

[0095] S14, if the command is discarded, send the MCTP over SMBUS Get EID command to address 3Ah, i.e., SOM=1, EOM=1, TO=1, and set the destination EID to a non-specially defined EID, i.e., set the destination EID;

[0096] Specifically, the MCTP over SMBUS Get EID command is sent to address 3Ah via NVME-MI, i.e., SOM=1, EOM=1, TO=1, to set the destination EID to a non-specially defined EID, i.e., the destination sets the EID;

[0097] Specifically, the command MCTP over SMBUS Set EID with EID=11 is sent to address 3Ah via NVME-MI, which means the destination sets the EID.

[0098] S15, send the MCTP over SMBUS Get EID command again to the destination address 3Ah to set the EID, that is, SOM=1, EOM=1, TO=1;

[0099] Specifically, the MCTP over SMBUS GetEID command is sent again to the destination EID at address 3Ah via NVME-MI, i.e., SOM=1, EOM=1, TO=1. Since the destination EID has just been successfully assigned, the execution is successful.

[0100] S16, Obtain the value of the destination setting EID;

[0101] Specifically, the MCTP over SMBUS Get EID command is sent again to the destination address 3Ah, where SOM=1, EOM=1, TO=1.

[0102] S17, determine whether the value of the destination EID setting is equal to the set value; if the value of the destination EID setting is not equal to the set value, the destination EID setting fails, and the SSD MCTP control message EID setting is marked as invalid, and subsequent verification is stopped.

[0103] S18. If the destination EID value is equal to the set value, the verification is successful.

[0104] Specifically, after successful verification, the EID can be used as the access ID of the target device to read the MCTP version.

[0105] This invention can quickly and efficiently verify whether MCTP control message commands have reached the solid-state drive normally through the SMBUS link, and send the data to be replied back to the BMC through the MCTP transmission protocol. By verifying the EID, different EIDs can be set to avoid conflicts in communication with the same address.

[0119] The fifth judgment unit 130 is used to determine whether the command is discarded;

[0120] The sending setting unit 140 is used to send an MCTP over SMBUSGet EID command to address 3Ah if the command is dropped, i.e., SOM=1, EOM=1, TO=1, to set the destination EID to a non-specially defined EID, i.e., the destination setting EID.

[0122] The second acquisition unit 160 is used to acquire the value of the destination setting EID;

[0123] The sixth judgment unit 170 is used to determine whether the value of the destination setting EID is equal to the set value;

[0124] The verification unit 180 is used to verify successfully if the value of the destination EID is equal to the set value.

[0125] In the allocation unit 20, the default address D4 of the device is changed to a new address other than D4h or C2h, namely 3Ah, by using the SMBUS ARP address allocation command.

[0126] The device also includes a default unit, which is used to indicate that the destination EID has been successfully configured if the value of the destination EID is not equal to the default value.

[0127] The device further includes a failure unit, which is used to fail to set the destination EID if the value of the destination EID setting is not equal to the setting value.

For the sake of convenience and brevity, these details will not be repeated here.

[0129] The aforementioned SMBUS-based SSD MCTP control message verification device can be implemented as a computer program, which can, for example... Figure 3 It runs on the computer device shown.
