Subject: [Patch v3 00/19] CIFS: Implement SMB Direct
Date: Tue, 29 Aug 2017 12:28:56 -0700 [thread overview]
Message-ID: <20170829192915.26251-1-longli@exchange.microsoft.com> (raw)
From: Long Li <longli@microsoft.com>
Starting with SMB2 dialect 3.0, Microsoft introduced SMBDirect transport
protocol for transferring upper layer (SMB2) payload over RDMA via Infiniband,
RoCE or iWARP. The prococol is published in [MS-SMBD]
(https://msdn.microsoft.com/en-us/library/hh536346.aspx).
Patch v2 added RDMA read/write via memory registration, and addressed
feedbacks on v1.
Patch v3 improved performance by introducing an additional queue for handling
empty packets and reducing lock contention on IRQ path. Also added light
weight profiling by reading TSC and addressed feedbacks on v2.
Long Li (19):
CIFS: Add rdma mount option
CIFS: SMBD: Add SMBDirect protocol and transport constants
CIFS: SMBD: Implement SMBDirect transport
CIFS: SMBD: Add SMBDirect transport to SMB connection and Makefile
CIFS: SMBD: Connect to SMBDirect session

CIFS: SMBD: Destroy SMBDirect session on shutdown or umount
CIFS: SMBD: Set SMBDirect maximum read or write size for I/O
CIFS: SMBD: Receive data from SMBDirect
CIFS: SMBD: Send data through SMBDirect
CIFS: SMBD: Define memory registration for I/O data
CIFS: SMBD: Fix the definition for SMB2_CHANNEL_RDMA_V1_INVALIDATE
CIFS: SMBD: Implement SMB write via RDMA read through memory
registration

CIFS: SMBD: Add parameter rdata to smb2_new_read_req
CIFS: SMBD: Read correct returned data length for RDMA write (SMB
read) I/O
CIFS: SMBD: Implement SMB read via RDMA write through memory
registration
CIFS: SMBD: Deregister memory when finishing SMB read
CIFS: SMBD: Add SMBDirect debug counters
