Hello, Please test the binaries. The NFSv4.2/4.1 client is for Windows 10/11 AMD64+x86 and Windows Server 2019+2022/AMD64, but interoperability feedback with NFSv4.1/NFSv4.2 servers based on Linux 6.6+ LTS and 6.16+ would be great. News: See announcement below; xcopy.exe/cmd.exe copy/MS Explorer file copy acceleration via NFS server side copies and copy-by-block-cloning are IMO the most interesting new features (cloning now works with Linux nfsd exporting btrfs or xfs filesystems, server side copy with all filesystems), because it's "on" by default for all Windows 11 applications which copy files, followed by wings.exe (Linux users read man sg(1)) with powershell support.

To: <ms-nfs41-client-devel@xxxxxxxxxxxxxxxxxxxxx> Hi! ---- We've created a set of test binaries for the NFSv4.2/NFSv4.1 filesystem client driver for Windows 10 (32+64bit), Windows 11+Windows Server 2019/2022 (64bit), based on https://github.com/kofemann/ms-nfs41-client (commit id #46aa157ba1031b15d6a3539d7204c95da32fe0d6, 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_20250906_10h29m_git46aa157.readme - http://www.nrubsig.org/people/gisburn/work/msnfs41client/releases/testing/msnfs41client_cygwin_64bit32bit_binaries_20250906_10h29m_git46aa157.html (experimental HTML version) ** Download URL: - http://www.nrubsig.org/people/gisburn/work/msnfs41client/releases/testing/msnfs41client_cygwin_64bit32bit_binaries_20250906_10h29m_git46aa157.tar.bz2 ** Download hash sums: SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20250906_10h29m_git46aa157.html)= 5e390967c8892b720cf8a426ceb78e33d6f10ecb4c24601dfc9892b4366fa276 SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20250906_10h29m_git46aa157.readme)= 4981aa747db803f57c1756edaa23e9528dcc2b4620b358f4aceaf4aade2d26aa SHA2-256(msnfs41client_cygwin_64bit32bit_binaries_20250906_10h29m_git46aa157.tar.bz2)= bdd4c2bab46d7c1970dd5dfc995bdcd03bd84df5478a04191d152688d255f795 ** Major changes since the last release: - /sbin/nfs_globalmount, a new tool for Administrators to manage global/machine-wide mounts which are available to all Windows users/services/logons - 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) roland.mainz@xxxxxxxxxxx \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ Ms-nfs41-client-devel mailing list Ms-nfs41-client-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ms-nfs41-client-devel
