[Bug 1481780] Re: ipmitool 1.8.13 needs 2 patches for OpenPower systems

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ New hardware enablement: enables IPMI usage over USB transport, for those systems providing such an interface.
+ 
+ [Test case]
+ 1) run 'ipmitool -I usb sensor'
+ 
+ Without a patched ipmitool, this will not work. With a version of
+ ipmitool with USB interface support, sensor data available for the
+ system will be listed.
+ 
+ [Regression potential]
+ In the event that the user selects the USB interface (-I usb) on systems which do not support it, ipmitool requests will fail. The new interface code is a new completely separated code path that is unlikely to interfere with any existing code. The additional memcpy change could cause extra data to be read or ignored coming from the BMC, by the ipmitool utility.

  In order to support those, the current ipmitool (1.8.13) in 14.04 needs to integrate 2 patches :
  - a fix for the hpm library :   https://sourceforge.net/p/ipmitool/bugs/38 which has been commited : ff80a188f3dc1eef105b2915361b1fce30ee4e4c
  - a feature request : http://sourceforge.net/p/ipmitool/feature-requests/58/ that has not been commited so far

  After testing the required patches onto 1.8.13, it appears that they do not apply cleanly and also that this
  does not require trivial changes to the patches. I started working on this, but I'd prefer to have David Wise's
  opinion on any requirements needed (commits/features) that could have been done between ipmitool 1.8.13 and current git master, not to lose time.
  I sent a mail to David and am waiting for his feedback.

  After contacting David Wise, he thinks that we can make the changes and provide a patch quickly once we have the correct source version.
  I provided the necessary info so that he can have the exact source version of ipmitool used in Ubuntu 14.04 (that is http://packages.ubuntu.com/source/trusty-updates/ipmitool) and how to use this in order to setup his source tree.
