To: <[email protected]> Hi! ---- We've created a set of test binaries for the NFSv4.2/NFSv4.1 filesystem client driver for Windows 10 (32bit x86, x86-64, ARM64), Windows 11 (x86-64, ARM64)+Windows Server 2019/2022/2025 (x86-64, ARM64), based on https://github.com/kofemann/ms-nfs41-client (commit id #6b11d381c68c0fae5a777b9980e71058abdc1d61, git bundle in tarball), for testing and feedback. ** FULL release readme: - http://www.nrubsig.org/people/gisburn/work/msnfs41client/releases/testing/msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.readme - http://www.nrubsig.org/people/gisburn/work/msnfs41client/releases/testing/msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.html ** Download URL (all architectures+platforms): - http://www.nrubsig.org/people/gisburn/work/msnfs41client/releases/testing/msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.tar.bz2 ** Download hash sums: SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.html)= c45c7fb36bffb9ff8a1dfa51b95c6c551655b858e6336e7a6002d3837507ba99 SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.readme)= 369d1e3850f4b9279415924607cd1c2c31a09ca663dba3b30263da200cac77f9 SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20251217_18h32m_git6b11d38.tar.bz2)= 531606d4aed8f817da646a71970cf7b5dd56b11aee733ba3fa7ccac9aa546746 ** Major changes since the last release: - Support for Windows "SRVOpen collapsing", which enables file handles with the access/permission/etc attributes to share one NFS file handle (saving open/close round trips to the NFS server) - Added support for Windows Server 2025 - Symlinks are now using the group defined by Win32 PrimaryGroup (which can be set via Cygwin newgrp(1)/|setgid()| or winsg(1)) - Added a new standalone tool called catdbgprint.exe which can be used to listen to Windows kernel |DbgPrint()| debug messages (DbgView.exe from Windows Internals still works, but this avoids installing an extra tool) - Added support for Windows "Extended Create Parameters" ECP QUERY_ON_CREATE |QoCFileStatInformation| and |QoCFileLxInformation| - Added support for setting a file's ACL at file creation time - Bugfixes for FreeBSD NFS server - Fixed issues probing sparse files when using the nfs-ganesha NFS server - Disk and CDROM/DVD images can now be mounted via https://github.com/gisburn/filedisk-sparse/ - UNC path format changed to <hostname>@<protocol>@<port>, e.g. ournfsserver@NFS@2049, to support future transport+mount options (e.g. RDMA , TLS/SSL etc.) - Window 11/ARM64 is now supported (native aarch64 kernel module and nfs*.exe userland utilities) - /sbin/nfs_globalmount, a new tool for Administrators to manage global/machine-wide mounts which are available to all Windows users/services/logons - New "nfsclientdctl" utility to change the NFS client daemon parameters at runtime - support for case-insensitive filesystems (e.g. Windows Server NTFS) - NFS referrals now work with custom (non-TCP/2049) port numbers - Implemented |FSCTL_OFFLOAD_READ|+|FSCTL_OFFLOAD_WRITE| (e.g. used by Windows 10 xcopy, Windows Explorer etc) for server-side NFSv4.2 COPY - Better FreeBSD 14 nfsd compatibility - DFS service no longer needs to be disabled - More software tested for compatibility: MariaDB, Microsoft Office 2016, Visual Studio 2022 work with msnfs41client - Volume label is now the nfs://-URL to the server (up to 31 characters for Windows Explorer compatibility) - Support for user and group names with non-ASCII (e.g. Unicode) names (like German umlauts) in ms-nfs41-client, winsg.exe etc. - winsg.exe now has a /P option to run powershell.exe with the requested group - nfs_mount.exe now enforces that normal mounts need nfs://-URLs with absolute paths, and "public NFS" mounts need relative paths in a nfs://-URL - sec=none support - Improved /sbin/cygwinaccount2nfs4account script to better handle creation of Windows Domain accounts on the NFS server side - *.(exe|dll) executables are now signed with a WDK test signature, helping with *rare* cases that Windows Defender with paranoid settings wrongly recognising the binaries as potential threads. A *.cer certificate file is supplied which can be imported into the Windows Defender to whitelist the binaries if this happens. - Support for FSCTL_DUPLICATE_EXTENTS_TO_FILE, which allows Windows 11 applications which use |CopyFile2()| (like cmd.exe copy, xcopy.exe etc) to copy files via block cloning. Requires NFSv4.2 NFS server with { CLONE, SEEK, DEALLOCATE } support, exporting a filesystem which supports block cloning (e.g. btrfs, xfs). This includes correct cloning of sparse files. - Sparse file support (requires NFSv4.2 server { SEEK, ALLOCATE, DEALLOCATE } and the |FATTR4_WORD1_SPACE_USED| attr), including hole/data range enumeration, punching holes etc., e.g. $ fsutil sparse queryrange mysparsefile # - Improved Windows Extended Attribute (EA) support (requires NFS >= v4.1 server with "Named Attribute" support ("OPENATTR")), including create/read/write/delete - Improved WSL support - Support for Storage32-API (e.g. enables use of *.msi installer files on NFS filesystems) - Cygwin /usr/bin/svn and Windows '/cygdrive/c/Program Files/Git/cmd/git' now work - Illumos NFSv4.2 server is now supported - Solaris 11.4 NFSv4.1 server is now supported - Windows Server 2022 NFSv4.1 server is now supported (compared to WS2019 this NFS server version has ACL support) ** Please send comments, bugs, test reports, complaints etc. to the MailMan mailing list at https://sourceforge.net/projects/ms-nfs41-client/lists/ms-nfs41-client-devel ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [email protected] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ Ms-nfs41-client-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ms-nfs41-client-devel -- Cedric Blancher <[email protected]> [https://plus.google.com/u/0/+CedricBlancher/] Institute Pasteur -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
