Can I port 4.4BSD-Lite's TCP/IP protocol stack soure code to my own OS kernel which is GPL Licence?
Modern 2- or 3-clause BSD licenses are fully compatible with the GPL, as are most "simple, permissive" licenses like the MIT/X11, Zlib, and similar licenses. The old 4-clause license with the "advertising clause" is not GPL-compatible.
I know that 4.4BSD-Lite is BSD Licenced. Is it legal to port BSD Licenced code and change it to GPL licence?
You are not allowed to remove the copyright statement or the original BSD license, but you can take BSD-licensed code and combine it with other software to create a derivative work which you then distribute under the GPL or even a proprietary license, if you wish.
Eric Raymond and his wife, Catherine (who is a lawyer), have written some documentation about this specific issue here:
