| H A D | svc_rdma.h | 25fd86ec Mon May 07 14:28:09 CDT 2018 Chuck Lever <chuck.lever@oracle.com> svcrdma: Don't overrun the SGE array in svc_rdma_send_ctxt
Receive buffers are always the same size, but each Send WR has a
variable number of SGEs, based on the contents of the xdr_buf being
sent.
While assembling a Send WR, keep track of the number of SGEs so that
we don't exceed the device's maximum, or walk off the end of the
Send SGE array.
For now the Send path just fails if it exceeds the maximum.
The current logic in svc_rdma_accept bases the maximum number of
Send SGEs on the largest NFS request that can be sent or received.
In the transport layer, the limit is actually based on the
capabilities of the underlying device, not on properties of the
Upper Layer Protocol.
