- Bug fixes for Win11
- Volume label is now an URL to the NFS server, e.g. nfs://hostname/
- winsg.exe now supports PowerShell directly

cloning now works for 32bit applications)
- The NFS driver and wings.exe now support non-ASCII characters (e.g
french circumflex)

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
#d02fdef0eb50ffead29d88bd6e6899cfc49decd7, git bundle in tarball), for
testing and feedback.

** Major changes since the last release:
- Maximum number of ACEs in ACLs has been increased to 128
- 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
- |FSCTL_DUPLICATE_EXTENTS_TO_FILE| (file/block cloning) now works
with 32bit processes on 64bit kernel
- 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
- Various documentation+READMEs converted into a single DocBook/XML
documentation
- *.(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)
