Subject: [Patch v2 00/19] CIFS: Implement SMBDirect
Date: Sun, 20 Aug 2017 12:04:24 -0700 [thread overview]
Message-ID: <1503255883-3041-1-git-send-email-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).
The patch v2 added RDMA read/write via memory registration, and addressed feedbacks on v1.
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: Reconnect 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: Read 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: Use registered memory RDMA read for SMB write
CIFS: SMBD: Deregister memory when finishing SMB write
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: Do not read from transport on registered memory RDMA write
(SMB READ)
CIFS: SMBD: Deregister memory when finishing SMB read
CIFS: SMBD: Add SMBDirect debug counters
