Subject: RE: [PATCH v7 00/13] ksmbd: introduce new SMB3 kernel server
> This is the patch series for ksmbd kernel server.
>
> What is ksmbd ?
> ===============
>
> The SMB family of protocols is the most widely deployed network filesystem protocol, the default on
> Windows and Macs (and even on many phones and tablets), with clients and servers on all major
> operating systems, but lacked a kernel server for Linux. For many cases the current userspace server
> choices were suboptimal either due to memory footprint, performance or difficulty integrating well
> with advanced Linux features.
>
> ksmbd is a new kernel module which implements the server-side of the SMB3 protocol.
> The target is to provide optimized performance, GPLv2 SMB server, better lease handling (distributed
> caching). The bigger goal is to add new features more rapidly (e.g. RDMA aka "smbdirect", and recent
> encryption and signing improvements to the protocol) which are easier to develop on a smaller, more
> tightly optimized kernel server than for example in Samba. The Samba project is much broader in scope
> (tools, security services, LDAP, Active Directory Domain Controller, and a cross platform file server
> for a wider variety of purposes) but the user space file server portion of Samba has proved hard to
> optimize for some Linux workloads, including for smaller devices. This is not meant to replace Samba,
> but rather be an extension to allow better optimizing for Linux, and will continue to integrate well
> with Samba user space tools and libraries where appropriate.
> Working with the Samba team we have already made sure that the configuration files and xattrs are in a
> compatible format between the kernel and user space server.

> ksmbd feature status
> ====================
>
> ============================== =================================================
> Feature name Status
> ============================== =================================================
> Dialects Supported. SMB2.1 SMB3.0, SMB3.1.1 dialects
> (intentionally excludes security vulnerable SMB1 dialect).
> Auto Negotiation Supported.
> Compound Request Supported.
> Oplock Cache Mechanism Supported.
> SMB2 leases(v1 lease) Supported.
> Directory leases(v2 lease) Planned for future.
> Multi-credits Supported.
> NTLM/NTLMv2 Supported.
> HMAC-SHA256 Signing Supported.
> Secure negotiate Supported.
> Signing Update Supported.
> Pre-authentication integrity Supported.
> SMB3 encryption(CCM, GCM) Supported. (CCM and GCM128 supported, GCM256 in progress)
> SMB direct(RDMA) Partially Supported. SMB3 Multi-channel is required
> to connect to Windows client.
> SMB3 Multi-channel Partially Supported.
> SMB3.1.1 POSIX extension Supported.
> ACLs Partially Supported. only DACLs available, SACLs
> (auditing) is planned for the future. For
> ownership (SIDs) ksmbd generates random subauth
> values(then store it to disk) and use uid/gid
> get from inode as RID for local domain SID.
> The current acl implementation is limited to
> standalone server, not a domain member.
> Integration with Samba tools is being worked on to
> allow future support for running as a domain member.
> Kerberos Supported.
> Durable handle v1,v2 Planned for future.
> Persistent handle Planned for future.
> SMB2 notify Planned for future.
> Sparse file support Supported.
> DCE/RPC support Partially Supported. a few calls(NetShareEnumAll,
> NetServerGetInfo, SAMR, LSARPC) that are needed
> for file server handled via netlink interface from
> ksmbd.mountd. Additional integration with Samba
> tools and libraries via upcall is being investigated
> to allow support for additional DCE/RPC management
> calls (and future support for Witness protocol e.g.)
> ksmbd/nfsd interoperability Planned for future. The features that ksmbd
> support are Leases, Notify, ACLs and Share modes.
> ============================== =================================================
>
> All features required as file server are currently implemented in ksmbd.
> In particular, the implementation of SMB Direct(RDMA) is only currently possible with ksmbd (among
> Linux servers)

>
> Stability
> =========

> It has been proved to be stable. A significant amount of xfstests pass and are run regularly from

I missed updating test result in cover letter.

> In addition regression tests using the broadest SMB3 functional test suite (Samba's "smbtorture") are

> It has already been used by many other open source toolkits and commercial companies that need NAS
> functionality. Their issues have been fixed and contributions are applied into ksmbd. Ksmbd has been
> well tested and verified in the field and market.
