VirtualBox Shared Folders: progress report
I spent Labor Day weekend laboring on VBox shared folders support for FreeBSD. It’s been some time since I worked on it last time so I had to refresh my memory first. Things have moved on since then - VBox in ports was updated to version 5, but fortunately Li-Wen synced up freebsd-vboxfs repo to the latest version. After three days of laid-back hacking I am glad to announce that following VOPs are kind of implemented (in no particular order): lookup, access, readdir, read, getattr, readlink, remove, rmdir, symlink, close, create, open, write. “Kind of implemented” means that I was able to mount directory, traverse it, read file, calculate md5 sums and compare with host’s md5sum, create/remove directories, unzip zip file, etc but I doubt it would survive stress-test. Locking is all wrong at the moment and read/write VOPs allocate buffers for every operation. ...
