So you can’t I have come across the tiny scheme files, and I can see that Sandbox.kext is running the interpreter, so presumably the input that I feed it must be a bit off. > > * The item’s path, using `vn_getpath` or `vn_getpath_fsenter` > > * The name of the file system on which the item resides, using > `vnode_mount ` and `vfs_name` > > * The mount point of that file system, using `vnode_mount` and > `vfs_statfs` > > * The item’s mode, using `vnode_getattr` with `va_mode` > > * The item’s type, using `vnode_getattr` with `va_type` > > * The item’s rdev, using `vnode_getattr` with `va_type` and `va_rdev` Thank you, I was hoping for exactly this sort of email. I will keep digging. There have been some surprises, like that of ioctl GET_BOOT_INFO insists that the root vnode be tagged as VT_HFS (and not VT_ZFS) for it to bother calling us. (The comment in XNU sources suggest 'future enhancement') BUT, that didn't make any difference, so hopefully I won't have to "lie" about the tag. > You may be able to trace these callbacks from the Sandbox kext to the > kernel to see where things have gone wrong, perhaps comparing the HFS > and ZFS cases side by side. Unfortunately I can no longer trace the incoming HFS VNOP calls, but perhaps I can dtrace directly on VNOP_* and just filter out the noise (including dtrace itself sending data with VNOP_WRITE).
