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: 562d4af32ec2213061f844b3838223fd7711b56a Bin Meng (5): qemu/xattr.h: Exclude <sys/xattr.h> for Windows hw/9pfs: Drop unnecessary *xattr wrapper API declarations hw/9pfs: Replace the direct call to xxxat() APIs with a wrapper hw/9pfs: update helper qemu_stat_rdev() hw/9pfs: Add a helper qemu_stat_blksize() Guohuai Shi (12): hw/9pfs: Add missing definitions for Windows hw/9pfs: Implement Windows specific utilities functions for 9pfs hw/9pfs: Update the local fs driver to support Windows hw/9pfs: Support getting current directory offset for Windows hw/9pfs: Disable unsupported flags and features for Windows hw/9pfs: Update v9fs_set_fd_limit() for Windows hw/9pfs: Add Linux error number definition hw/9pfs: Translate Windows errno to Linux value fsdev: Disable proxy fs driver on Windows hw/9pfs: Update synth fs driver for Windows tests/qtest: virtio-9p-test: Adapt the case for win32 meson.build: Turn on virtfs for Windows meson.build | 10 +- fsdev/file-op-9p.h | 33 + hw/9pfs/9p-linux-errno.h | 151 ++++ hw/9pfs/9p-local.h | 8 + hw/9pfs/9p-util.h | 137 +++- hw/9pfs/9p.h | 43 ++ include/qemu/xattr.h | 4 +- tests/qtest/libqos/virtio-9p-client.h | 7 + fsdev/qemu-fsdev.c | 2 + hw/9pfs/9p-local.c | 386 ++++++++++- hw/9pfs/9p-synth.c | 5 +- hw/9pfs/9p-util-win32.c | 963 ++++++++++++++++++++++++++ hw/9pfs/9p.c | 90 ++- hw/9pfs/codir.c | 2 +- fsdev/meson.build | 1 + hw/9pfs/meson.build | 8 +- 16 files changed, 1759 insertions(+), 91 deletions(-) create mode 100644 hw/9pfs/9p-linux-errno.h create mode 100644 hw/9pfs/9p-util-win32.c -- 2.25.1
