Summarizing from the above, the following Linux unix socket features are either currently unavailable or unsupported in the Windows unix socket implementation. The socket file itself that is created as part of the bind call is a custom NTFS reparse point. The Windows kernel networking stack provides a very pluggable and extensible model, that makes it easy to support new network providers.

Majority of the functionality for the Windows AF_UNIX is implemented in the Windows kernel in a driver : afunix.sys. See the man page on AF_UNIX for more details on the security. The same level of security is available and enforced on the Windows unix socket implementation. Similarly, for connecting to a stream socket, the connecting process should have write permission on the socket. The creation of the new socket file will fail if the calling process does not has write permission on the directory where the file is being created. For example, the bind socket API creates a ‘socket’ file with the given pathname. C ommunication over unix sockets can be secured by controlling the file (or directory) permissions on the pathname sockets ( or the parent directory ). Unix sockets provide a mechanism for secure communication. Although, one of the socket API’s socketpair that generates unnamed sockets, itself is not supported in Winsock 2.0. This is also supported on Windows unix socket implementation. Lastly, ‘unnamed’ sockets, where the socket is bound to a pathname with no name. The one difference noteworthy here is that the Windows unix socket implementation currently does not support the auto bind feature whereby an abstract address is auto-generated by the implementation on behalf of the user. Windows implementation of AF_UNIX socket can also accept abstract addresses. The second category is the ‘abstract’ socket address where the first character in ‘ sun_path ’ is a null byte. You can expect the same from the Windows implementation, where ‘ sun_path ’ specifies a Win32 UTF-8 file system path. ‘pathname’ sockets are bound to the filesystem, where in the ‘ sun_path ’ member of the struct is used to specify a null-terminated UTF-8 file system path. ‘pathname’, ‘abstract’ and ‘unnamed’ sockets. There are three different addressing formats for unix sockets. In the Windows implementation of the unix socket, we have kept the name, definition and semantics of the unix socket address the same as that in Linux, to make cross-platform development easier. The ‘ sockaddr_un ’ structure is used for defining the address of a unix socket. Support for the datagram (SOCK_DGRAM) can be considered in future depending on the adoption, feedback and scenario s. Currently, the support only exists for the stream ( SOCK_STREAM ) socket type, which is a connection-oriented protocol for one-to-one communication. Starting this build, two Win 32 process es can use the AF_UNIX address family over Winsock API (which is very similar to the BSD socket API) to communicate with each other. Such differences make it difficult to port unix socket applications from Linux to Windows and vice versa up until now!īuild 17063 brings native support for the unix socket to Windows. There is no direct equivalent of that in named pipes. BSD Socket API provides a bidirectional close semantics using shutdown. For example, one such place where these two constructs differ (other than the API) is terminating the connection. But, calling conventions are different between the named pipes and sockets, making writing low-maintenance cross-platform applications difficult. On Windows, there were some alternatives for local IPC, such as named pipes. Support for the unix socket has existed both in BSD and Linux for the longest time, but, not on Windows. Unix sockets allow inter-process communication (IPC) between process es on the same machine. Beginning in Insider Build 17063, you’ll be able to use the unix socket ( AF_UNIX ) address family on Windows to communicate between W in32 processes.
