The apple code looks like a decent starting point if someone wants to try this in-kernel. For one, it's definitely derived from the existing FreeBSD smbfs code. SMB2 and 3 support has been added, and I didn't examine how much the vnode interface was changed. But this is suggestive that reconciling it into our tree would not be awful. One concern is the license on some portions of the new apple code is the APSL2. AIUI, and obviously IANAL, the APSL2 is somewhat similar to the file-basis copyleft property that the CDDL has. I don't know if we have any existing APSL2 code in tree, or if the foundation's lawyers would approve it. Perhaps the non-BSDL files would have to live in a sys/apsl subdirectory. That doesn't seem like a blocker for adapting Apple's smbfs implementation, but again, not a lawyer, and I haven't even skimmed the code.
