Apple sources can be found there 
https://opensource.apple.com/source/smb/ with all the history from SMBv1 
to SMBv3. The files have original copyright header from 2001 Boris Popov 
(same as FreeBSD) but otherwise it is very different code due to 
different kernel interfaces and so on.
With Apple and Illumos sources it is possible to have smbfs in FreeBSD 
upgraded to v2 or v3 but very skilled programmer is needed for this 
work. And for the past years there is none interested in this work.
