#501 Response to system GUID command is not as per the IPMI specification
Noticed reading System GUID command is returning invalid value. IPMItool is not returing the data in the correct format.
Sytem GUID
61a39523-78f2-11e5-9862-e6402cfc3223
./ipmitool -I lanplus -H x.x.xxx.xxx -P 0penBmc -C 1 mc guid System GUID : 2cfc3223-e640-9862-e511-f2782395a361
Expected
2332fc2c40e6-6298-e511-f278-2395a361
Issue noticed is the below structure defined in ./include/ipmitool/ipmimc.h is not as per IPMI specification (Refer to section 20.8)
/ Structure follow the IPMI V.2 Rev 1.0
* See Table 20-10 /
struct ipmi_guid_t {
uint32_t time_low; / timestamp low field /
uint16_t time_mid; / timestamp middle field /
uint16_t time_hi_and_version; / timestamp high field and version number /
uint8_t clock_seq_hi_variant;/ clock sequence high field and variant /
uint8_t clock_seq_low; / clock sequence low field /
uint8_t node[6]; / node /
} ATTRIBUTE_PACKING;
As per specification the structure should have been defined as
struct ipmi_guid_t {
uint8_t node[6]; / node /
uint8_t clock_seq_low; / clock sequence low field /
uint8_t clock_seq_hi_variant;/ clock sequence high field and variant /
uint16_t time_hi_and_version; / timestamp high field and version number /
uint16_t time_mid; / timestamp middle field /
uint32_t time_low; / timestamp low field /
} ATTRIBUTE_PACKING;
