At present there is no Windows support for 9p file system.
This series adds initial Windows support for 9p file system.
'local' file system backend driver is supported on Windows,
including open, read, write, close, rename, remove, etc.
All security models are supported. The mapped (mapped-xattr)
security model is implemented using NTFS Alternate Data Stream
(ADS) so the 9p export path shall be on an NTFS partition.
'synth' driver is adapted for Windows too so that we can now
run qtests on Windows for 9p related regression testing.
Example command line to test:
"-fsdev local,path=c:\msys64,security_model=mapped,id=p9 -device virtio-9p-pci,fsdev=p9,mount_tag=p9fs"
Base-commit: 13356edb87506c148b163b8c7eb0695647d00c2a
Changes in v4:
- Fixed 9pfs mounted as read-only issue on Windows host, adding a
win32_error_to_posix() to translate Windows native API error to
POSIX one.
- Fixed errors of handling symbolic links
- Added forward declaration to avoid using 'void *'
- Implemented Windows specific xxxdir() APIs for safe directory access
Sorry to look a bit late at this series, I don't know what was discussed previously.
My general feeling is that a lot of this FS portability work would be better handled by using GIO (even though this may add some extra dependency). GIO lacks some features on win32 (for example xattributes on win32), but they could have been proposed there too and benefiting other apps.
Btw, I would not count on mingw adding support for flags/API (S_IFLNK etc), that do not make sense on win32. Did you request them?
I suppose the 9pfs maintainers (Greg, Christian) will have to decide. I can take a deeper look if the overall approach is approved, and as needed.
