Second version of NFS/RDMA client patches proposed for merge into v4.7. Thanks in advance for any review comments! Attempt to fence memory regions after a signal interrupts a synchronous RPC. This prevents a server from writing a reply into a client's memory after the memory has been released due to a signal. Support providing a Read list and Reply chunk together in one RPC call. This is a pre-requisite for using krb5i or krb5p on RPC/RDMA. In addition, the following changes and fixes are included: - Use new ib_drain_qp() API - Advertise max size of NFSv4.1 callbacks on RPC/RDMA - Prevent overflowing the server's receive buffers - Send small NFS WRITEs inline rather than using a Read chunk - Detect connection loss sooner Available in the "nfs-rdma-for-4.7" topic branch of this git repo: git://git.linux-nfs.org/projects/cel/cel-2.6.git Or for browsing: http://git.linux-nfs.org/?p=cel/cel-2.6.git;a=log;h=refs/heads/nfs-rdma-for-4.7 Changes since v1: - Rebased on v4.6-rc5 - Updated patch description for "Avoid using Write list for ..." --- Chuck Lever (18): sunrpc: Advertise maximum backchannel payload size xprtrdma: Bound the inline threshold values xprtrdma: Limit number of RDMA segments in RPC-over-RDMA headers xprtrdma: Prevent inline overflow xprtrdma: Avoid using Write list for small NFS READ requests xprtrdma: Update comments in rpcrdma_marshal_req() xprtrdma: Allow Read list and Reply chunk simultaneously xprtrdma: Remove rpcrdma_create_chunks() xprtrdma: Use core ib_drain_qp() API xprtrdma: Rename rpcrdma_frwr::sg and sg_nents xprtrdma: Save I/O direction in struct rpcrdma_frwr xprtrdma: Reset MRs in frwr_op_unmap_sync() xprtrdma: Refactor the FRWR recovery worker xprtrdma: Move fr_xprt and fr_worker to struct rpcrdma_mw xprtrdma: Refactor __fmr_dma_unmap() xprtrdma: Add ro_unmap_safe memreg method xprtrdma: Remove ro_unmap() from all registration modes xprtrdma: Faster server reboot recovery fs/nfs/nfs4proc.c | 10 - include/linux/sunrpc/clnt.h | 1 include/linux/sunrpc/xprt.h | 1 include/linux/sunrpc/xprtrdma.h | 4 net/sunrpc/clnt.c | 17 + net/sunrpc/xprtrdma/backchannel.c | 16 + net/sunrpc/xprtrdma/fmr_ops.c | 134 +++++++-- net/sunrpc/xprtrdma/frwr_ops.c | 214 ++++++++------- net/sunrpc/xprtrdma/physical_ops.c | 39 ++- net/sunrpc/xprtrdma/rpc_rdma.c | 517 ++++++++++++++++++++++-------------- net/sunrpc/xprtrdma/transport.c | 16 + net/sunrpc/xprtrdma/verbs.c | 91 ++---- net/sunrpc/xprtrdma/xprt_rdma.h | 42 ++- net/sunrpc/xprtsock.c | 6 14 files changed, 674 insertions(+), 434 deletions(-) -- Chuck Lever -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
