Not all of 2.2 is GPL.  Many of the NASL scripts are not, and this  
includes ALL of the SMB stuff.  Only the engine is GPL.  All of the  
SMB stuff (meaning the functions to connect to Windows shares and  
query the registry and check SMB specific "stuff") is implemented in  
NASL code, not in the engine.  When 2.2 came out, the shift to non- 
GPL scripts changed more than just the checks, some of the inner  
workings of NASL through include scripts and dependancies also became  
non-GPL, though I don't think most people noticed this.
