| | | | | | | | | | | | | | | | | | At some point, I recall that rpc_pipe_fs used RPC_DISPLAY_ALL.

| * SUNRPC: Remove duplicate universal address generationChuck Lever2009-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RPC universal address generation is currently done in several places: rpcb_clnt.c, nfs4proc.c xprtsock.c, and xprtrdma.c. Remove the redundant cases that convert a socket address to a universal address. The nfs4proc.c case takes a pre-formatted presentation address string, not a socket address, so we'll leave that one. Because the new uaddr constructor uses the recently introduced rpc_ntop(), it now supports proper "::" shorthanding for IPv6 addresses. This allows the kernel to register properly formed universal addresses with the local rpcbind service, in _all_ cases. The kernel can now also send properly formed universal addresses in RPCB_GETADDR requests, and support link-local properly when encoding and decoding IPv6 addresses.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The svcrdma module was incorrectly unmapping the RPCRDMA header page. On IBM pserver systems this causes a resource leak that results in running out of bus address space (10 cthon iterations will reproduce it). The code was mapping the full page but only unmapping the actual header length. The fix is to only map the header length. I also cleaned up the use of ib_dma_map_page() calls since the unmap logic always uses ib_dma_unmap_single(). I made these symmetrical.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This logic sets the connection parameter that configures the local device and informs the remote peer how many concurrent incoming RDMA_READ requests are supported. The original logic didn't really do what was intended for two reasons: - The max number supported by the device is typically smaller than any one factor in the calculation used, and - The field in the connection parameter structure where the value is stored is a u8 and always overflows for the default settings. So what really happens is the value requested for responder resources is the left over 8 bits from the "desired value". If the desired value happened to be a multiple of 256, the result was zero and it wouldn't connect at all. Given the above and the fact that max_requests is almost always larger than the max responder resources supported by the adapter, this patch simplifies this logic and simply requests the max supported by the device, subject to a reasonable limit. This bug was found by Jim Schutt at Sandia. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Acked-by: Tom Talpey <talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RPCRDMA requests that specify a read-list are fetched with RDMA_READ. Using an FRMR to map the data sink improves NFSRDMA security on transports that place the RDMA_READ data sink LKEY on the wire because the valid lifetime of the MR is only the duration of the RDMA_READ. The LKEY is invalidated when the last RDMA_READ WR completes. Mapping the data sink also allows for very large amounts to data to be fetched with a single WR, so if the client is also using FRMR, the entire RPC read-list can be fetched with a single WR.

| * | svcrdma: Add support to svc_rdma_send to handle chained WRTom Tucker2008-10-06
| | | | | | | | | | | | | | | | | | | | | | | | WR can be submitted as linked lists of WR. Update the svc_rdma_send routine to handle WR chains. This will be used to submit a WR that uses an FRMR with another WR that invalidates the FRMR. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
