[openib-general] ib_get_dma_mr and remote access

[Louis Laborde]

Hi there,

I would like to know if any application today uses ib_get_dma_mr verb with
remote access flag(s).

It seems to me that such a dependency could first, create a security hole
and second, make this verb hard to implement for some RNICs.

If only local access is required for this "special" memory region, can
it be implemented with the "Reserved LKey" or "STag0", whichever way it's
called?


Thanks,
Louis
