| H A D | storagecommands.hpp | f4d5e05e Wed Sep 22 14:58:08 CDT 2021 Johnathan Mantey <johnathanx.mantey@intel.com> Guarantee SDR Type12 byte alignment matches the IPMI spec
The Type12 structure used a uint24_t to assign storage for 3 reserved
bytes in the Type12 SDR definition. This turned out to be an issue as
the compiler promoted the uint24_t to a uint32_t, which added one
additional byte to the structure. This in turn pushed the trailing
bytes out of alignment.
The defintion has been changed to use an explicit uint8_t array that
is three bytes in size. This defines the structure in a way that
guarantees the size of the record is correct.
The structure has also had a constructor added to it to eliminate code
duplication, and to reduce the likelihood of errors caused by manual
calculation of values.
Tested:
Issued 'ipmitool sdr dump /tmp/sdrs.bin'
Performed a hex dump on the binary data and reviewed the Type12
records.
Confirmed all fields were correctly assigned, including the inclusion
of only 3 reserved bytes.
