KSMBD
KSMBD is an open-source software, open-source in-kernel CIFS/Server Message Block, SMB server created by Namjae Jeon for the Linux kernel. Initially the goal is to provide improved file I/O performance, but the bigger goal is to have some new features which are much easier to develop and maintain inside the kernel and expose the layers fully. Directions can be attributed to sections where Samba (software), Samba is moving to a few modules inside the kernel to have features like Remote direct memory access (RDMA) to work with actual performance gain. Features Implemented * SMB1(CIFS), SMB2/3 protocols for basic file sharing * Compound requests * oplock/lease * Large MTU(Multi-credit) * NT LAN Manager, NTLM/NTLMv2 * Auto negotiation * Hash-based message authentication code, HMAC-SHA256 Signing * Secure negotiate * Signing Update * Pre-authentication integrity(SMB 3.1.1, Windows 10) * SMB encryption (CCM, GCM) * SMB direct(RDMA) * WinACL (Security descriptor) * Kerberos * Dire ...

CIFS
Server Message Block (SMB) is a communication protocol used to share files, printers, serial ports, and miscellaneous communications between nodes on a network. On Microsoft Windows, the SMB implementation consists of two vaguely named Windows services: "Server" (ID: LanmanServer) and "Workstation" (ID: LanmanWorkstation). It uses NTLM or Kerberos protocols for user authentication. It also provides an authenticated inter-process communication (IPC) mechanism. SMB was originally developed in 1983 by Barry A. Feigenbaum at IBM to share access to files and printers across a network of systems running IBM's IBM PC DOS. In 1987, Microsoft and 3Com implemented SMB in LAN Manager for OS/2, at which time SMB used the NetBIOS service atop the NetBIOS Frames protocol as its underlying transport. Later, Microsoft implemented SMB in Windows NT 3.1 and has been updating it ever since, adapting it to work with newer underlying transports: TCP/IP and NetBT. SMB over QUIC was intro ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

NTLMv2
In a Windows network, NT (New Technology) LAN Manager (NTLM) is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. NTLM is the successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an older Microsoft product. The NTLM protocol suite is implemented in a Security Support Provider, which combines the LAN Manager authentication protocol, NTLMv1, NTLMv2 and NTLM2 Session protocols in a single package. Whether these protocols are used or can be used on a system, which is governed by Group Policy settings, for which different versions of Windows have different default settings. NTLM passwords are considered weak because they can be brute-forced very easily with modern hardware. Protocol NTLM is a challenge–response authentication protocol which uses three messages to authenticate a client in a connection-oriented environment (connectionless is similar), and a fourth additional message if integr ...

List Of Products That Support SMB
List of products that support the proprietary Server Message Block (SMB) protocol by IBM and later Microsoft. Implementations The list below explicitly refers to "SMB" as including an SMB client or an SMB server, plus the various protocols that extend SMB, such as the Network Neighborhood suite of protocols and the NT Domains suite. * Microsoft Windows includes an SMB client and server in all members of the Windows NT family and in Windows 95, Windows 98, and Windows Me. * The Linux kernel includes two SMB client implementations that use the Linux VFS, providing access to files on an SMB server through the standard file system API: smbfs and cifs. Also it is possible to mount the whole hierarchy of workgroups/servers/shares ("neighborhood") through FUSE kernel module and its userspace counterpart fusesmb. CIFSD, which is an In-kernel CIFS/SMB server implementation for Linux kernel, is available. It has the following advantages over user-space implementations: 1. It provides b ...

Comparison Of Operating System Kernels
A kernel is a component of a computer operating system. It serves as an intermediary connecting software to hardware, enabling them to work together seamlessly.A comparison of system kernels can provide insight into the design and architectural choices made by the developers of particular operating systems. Comparison criteria The following tables compare general and technical information for a number of widely used and currently available operating system kernels. Please see the individual products' articles for further information. Even though there are a large number and variety of available Linux distributions, all of these kernels are grouped under a single entry in these tables, due to the differences among them being of the patch level. See comparison of Linux distributions for a detailed comparison. Linux distributions that have highly modified kernels — for example, real-time computing kernels — should be listed separately. There are also a wide variety of minor B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DCE/RPC
DCE/RPC, short for "Distributed Computing Environment / Remote Procedure Calls", is the remote procedure call system developed for the Distributed Computing Environment (DCE). This system allows programmers to write distributed software as if it were all working on the same computer, without having to worry about the underlying network code. History DCE/RPC was commissioned by the Open Software Foundation in a "Request for Technology" (1993 David Chappell). One of the key companies that contributed was Apollo Computer, who brought in NCA - "Network Computing Architecture" which became Network Computing System (NCS) and then a major part of DCE/RPC itself. The naming convention for transports that can be designed (as architectural plugins) and then made available to DCE/RPC echoes these origins, e.g. ncacn_np ( SMB Named Pipes transport); ncacn_tcp (DCE/RPC over TCP/IP) and ncacn_http to name a small number. DCE/RPC's history is such that it's sometimes cited as an exampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Direct Memory Access
In computing, remote direct memory access (RDMA) is a direct memory access from the memory of one computer into that of another without involving either one's operating system. This permits high-throughput, low- latency networking, which is especially useful in massively parallel computer clusters. Overview RDMA supports zero-copy networking by enabling the network adapter to transfer data from the wire directly to application memory or from application memory directly to the wire, eliminating the need to copy data between application memory and the data buffers in the operating system. Such transfers require no work to be done by CPUs, caches, or context switches, and transfers continue in parallel with other system operations. This reduces latency in message transfer. However, this strategy presents several problems related to the fact that the target node is not notified of the completion of the request (single-sided communications). Acceptance As of 2018 RDMA had achieved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
