#453 Limit request sizes for the openIPMI interface to 37 bytes instead of 38.

[Dan Gora]

Hi All,

This patch is a fix for updating the hpm1 firmware via the 'ipmitool hpm upgrade' command over the KCS interface to a IPMC running the PPS IPMI code:

If there are any questions or comments, please let me know.

thanks

=====================================
Limit request sizes for the openIPMI interface to 37 bytes instead of 38.

The Pigeon Point Systems IPMI code only supports a maximum payload
data size of 37 bytes over the payload serial, KCS, SMB and LAN
interfaces, so we need to limit the maximum request size to 37 bytes
in the openIPMI plugin to prevent the KCS interface from overflowing
and stalling when HPM1 upgrades are performed.

Shouldn't this be based on OEM Vendor ID? It seems to me like this is a PPS specific change.

Thanks,
Z.

IPMI requires 38 bytes, so I think this shall be fixed in the IPMC. Also using "-z 37" on the command line shall give the same effect and can be used as a workaround.

Hi Dmitry,

Thanks.. I looked but I could not find where this was specified so I
assumed that PPS knew what they were doing... It would be nice for
this to work for boards already in the field, but since there is
already a command line workaround, that should be fine.

I'll withdraw this patch.

thanks again,
dan
