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' backend driver is updated only to build sucessuflly in a Windows build. Funtionalities are not tested as test cases do not run on Windows at present. Example command line to test: "-fsdev local,path=c:\msys64,security_model=mapped,id=p9 -device virtio-9p-pci,fsdev=p9,mount_tag=p9fs" Bin Meng (2): hw/9pfs: Compile 9p-local.c and 9p-proxy.c for Linux and macOS qemu/xatth.h: Update for Windows build Guohuai Shi (7): hw/9pfs: Extract common stuff to 9p-local.h fsdev: Add missing definitions for Windows in file-op-9p.h hw/9pfs: Add a 'local' file system backend driver for Windows hw/9pfs: Update 9p-synth.c for Windows build fsdev: Enable 'local' file system driver backend for Windows meson.build: Turn on virtfs for Windows host hw/9p: win32: Translate Windows error number to Linux value meson.build | 10 +- fsdev/file-op-9p.h | 33 + hw/9pfs/9p-linux-errno.h | 151 +++++ hw/9pfs/9p-local.h | 20 + hw/9pfs/9p-util.h | 41 ++ hw/9pfs/9p.h | 27 + include/qemu/xattr.h | 4 +- fsdev/qemu-fsdev.c | 2 + hw/9pfs/9p-local-win32.c | 1242 ++++++++++++++++++++++++++++++++++++++ hw/9pfs/9p-local.c | 14 - hw/9pfs/9p-synth.c | 5 +- hw/9pfs/9p-util-win32.c | 341 +++++++++++ hw/9pfs/9p-xattr.c | 113 ++++ hw/9pfs/9p.c | 98 ++- hw/9pfs/codir.c | 15 + fsdev/meson.build | 1 + hw/9pfs/meson.build | 12 +- 17 files changed, 2103 insertions(+), 26 deletions(-) create mode 100644 hw/9pfs/9p-linux-errno.h create mode 100644 hw/9pfs/9p-local-win32.c create mode 100644 hw/9pfs/9p-util-win32.c -- 2.25.1
