Subject: [PATCH 0/9] 9pfs: Add 9pfs support for Windows host
Date: Mon, 25 Apr 2022 22:26:56 +0800	[thread overview]
Message-ID: <20220425142705.2099270-1-bmeng.cn@gmail.com> (raw)

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"
