I don't have access out of the box to any vfs context nor extra data besides the vnode alone. I believe I can retrieve an usable vfs context using vfs_context_current(), and then use vfs_getattr() but I can't figure out how exactly they should be used. I tried looking for FreeBSD specific documentation and reading the source a couple times, but looks like I might be missing some macro to initialize the ctx or attr variables. goes something like this... (untested, of course:-) struct vnode_attr vattr; VATTR_INIT(&vattr); VATTR_WANTED(&vattr, va_mode); err = vnode_getattr(vp, &vattr, vfs_context_current()); Don't know the answer to the others, although you can probably figure out what crypto functions are in the kernel by looking ay the above sources. (If you use anything that isn't a kpi in your kext, you'll be walking on thin ice like I do. I figure that's ok for an open source project, but probably unwize for something that might be shipped to customers. Others might elaborate on this.) Good luck with it, rick _______________________________________________ Do not post admin requests to the list. They will be ignored.

You'll find Darwin quite different than FreeBSD w.r.t. this. The doc is use is the kernel sources (xnu-1228.tar.gz found under "Get the Source" on http://developer.apple.com). Look in xnu-1228/bsd/nfs/nfs_serv.c for an example. This email sent to site_archiver@lists.apple.com
