To compile the SMB3 server support as a module, choose M here: the module will be called ksmbd. You may choose to use a samba server instead, in which case you can choose N here. You also need to install user space programs which can be found in ksmbd-tools, available from https://github.com/cifsd-team/ksmbd-tools. More detail about how to run the ksmbd kernel server is available via the README file (https://github.com/cifsd-team/ksmbd-tools/blob/master/README). ksmbd kernel server includes support for auto-negotiation, Secure negotiate, Pre-authentication integrity, oplock/lease, compound requests, multi-credit, packet signing, RDMA(smbdirect), smb3 encryption, copy-offload, secure per-user session establishment via Kerberos or NTLMv2. if SMB_SERVER config SMB_SERVER_SMBDIRECT bool "Support for SMB Direct protocol" depends on SMB_SERVER=m && INFINIBAND && INFINIBAND_ADDR_TRANS || SMB_SERVER=y && INFINIBAND=y && INFINIBAND_ADDR_TRANS=y select SG_POOL default n help Enables SMB Direct support for SMB 3.0, 3.02 and 3.1.1.
