<P><FONT SIZE=2>The lowest level to catch all MAD buffer allocations is in the osm_vendor_get() call.</FONT>
<BR><FONT SIZE=2>It could certainly zero out the mad buffer it provides.</FONT>

<BR><FONT SIZE=2>> Hi Eitan,</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> With OpenSM, in general, is there an approach that is being used to</FONT>
<BR><FONT SIZE=2>> ensure the reserved fields at set to 0 on send ? I couldn't ascertain</FONT>
<BR><FONT SIZE=2>> this from the code and I do observe reserved fields set to non 0 on</FONT>
<BR><FONT SIZE=2>> send. One approach would be to clear the MAD when it is first obtained.</FONT>
<BR><FONT SIZE=2>> Another would be to clear the reserved fields in each SA record. I am</FONT>
<BR><FONT SIZE=2>> leaning towards the former approach. Is this the responsibility of the</FONT>
<BR><FONT SIZE=2>> vendor layer ?</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Thanks.</FONT>
