[Freeipmi-devel] Bug when querying bridged sensors

[GIRARD, MARC]

Hi FreeIPMI Team,

 

We experiment a bug when querying bridged sensors of a Bull GPU Blade.

 

This bug can be solved with the following patch :

(and probably with identical patch in kcs and ssif interface)

 

According to the chapter 7.4 of IPMI specifications, it seems that IPMI_BMC_IPMB_LUN_SMS_MSG_LUN (0x02) are used by devices sending request to system management software, so I suspect a bug concerning all platforms.

 

Thank you for your comments.
