[ewg] libibumad.so version bump in OFED 1.5.2

[Todd Rimmer]

I recently discovered that 3rd party applications built for OFED 1.5 will not run on OFED 1.5.2rc2.

The issue I found was that libibumad had changed from version 2 to version 3.  Can you provide insight as to why this change was made?

In reviewing the source code and change logs there do not seem to be any changes which would impact the application API nor application ABI.



I diffed the code and the main change seems to be:
diff -r --exclude CVS ./src/src/umad.c-orig ./src/src/umad.c
161a162,166
>   if (sys_read_string(port_dir, SYS_PORT_LINK_LAYER,
>       port->link_layer, UMAD_CA_NAME_LEN) < 0)
>       /* assume IB by default */
>       sprintf(port->link_layer, "IB");
>
The above change might imply an update to an rpm dependency on ib-kernel versions, but should not result in a new library version.  If the library version remained at 2, then applications built for OFED 1.5 would also run on OFED 1.5.2rc2 without recompile.




The ChangeLog simply says:
