Subject[[PATCH v1] 00/37] Implement SMBD protocol: Series 1
Date
From: Long Li <longli@microsoft.com>

SMB3 defines a protocol for transfer data over RDMA transport such as Infiniband, RoCE and iWARP. The prococol is published in [MS-SMBD] (https://msdn.microsoft.com/en-us/library/hh536346.aspx).

This is the series 1 of two patch sets. This patch set implements the SMBD transport for doing RDMA send/recv.

This patch set is the foundation of series 2 patch set, which implements sending upper layer RDMA read/write via memory registration.

Long Li (37):
[CIFS] SMBD: Add parsing for new rdma mount option
[CIFS] SMBD: Add structure for SMBD transport
[CIFS] SMBD: Add logging functions for debug
[CIFS] SMBD: Define per-channel SMBD transport parameters and default
values
[CIFS] SMBD: Implement API for upper layer to create SMBD transport
and establish RDMA connection
[CIFS] SMBD: Add definition and cache for SMBD response
[CIFS] SMBD: Implement receive buffer for handling SMBD response
[CIFS] SMBD: Define packet format for SMBD data transfer message
[CIFS] SMBD: Add SMBD request and cache
[CIFS] SMBD: Introduce wait queue when sending SMBD request
[CIFS] SMBD: Post a receive request
[CIFS] SMBD: Handle send completion from CQ
[CIFS] SMBD: Implement SMBD protocol negotiation
[CIFS] SMBD: Post a SMBD data transfer message with page payload
[CIFS] SMBD: Post a SMBD data transfer message with data payload
[CIFS] SMBD: Post a SMBD message with no payload
[CIFS] SMBD: Track status for transport
[CIFS] SMBD: Implement API for upper layer to send data
[CIFS] SMBD: Manage credits on SMBD client and server
[CIFS] SMBD: Implement reassembly queue for receiving data
[CIFS] SMBD: Implement API for upper layer to receive data
[CIFS] SMBD: Implement API for upper layer to receive data to page
[CIFS] SMBD: Implement API for upper layer to reconnect transport
[CIFS] SMBD: Support for SMBD keep alive protocol
[CIFS] SMBD: Support SMBD idle connection timer
[CIFS] SMBD: Send an immediate packet when it's needed
[CIFS] SMBD: Destroy transport when RDMA channel is disconnected
[CIFS] SMBD: Implement API for upper layer to destroy the transport
[CIFS] SMBD: Disconnect RDMA connection on QP errors
[CIFS] SMBD: Add SMBDirect transport to Makefile
[CIFS] Add SMBD transport to SMB session context
[CIFS] Add SMBD debug couters to CIFS debug exports
[CIFS] Connect to SMBD transport when specified in mount option
[CIFS] Reconnect to SMBD transport when it's used
[CIFS] Destroy SMBD transport on exit
[CIFS] Read from SMBD transport when it's used
[CIFS] Write to SMBD transport when it's used
