general question about rewritten code from scratch (about sunrpc issue)

[arief_mulya <arief@bna.telkomsel.co.id>]

Dear all,


CMIIW, but I understand one of RC bugs in glibc is the 
status of sunrpc code. And to make it release-able, 
re-implementation of this code is a must.

I also understand that Jeff Bailey, has a schedule to work 
on the issue on March. I like to help on re-implementing new 
sunrpc code, but I don't know what is the condition to 
re-implementing new code of existing code in order to change 
 the license.

Do I need to understand all the algorithm in sunrpc (in the 
meaning of, I should get a book about rpc and  read it 
thoroughly) and wrote my own version of code based on my 
understanding?

Or can I just read sunrpc sources, and build new codes based 
on what I read? Should it be completely different in 
structure with sun's implementation? Surely I cannot just do 
copy-pasting, but can I take some of the part of sun's 
sunrpc implementation and put it in my own code?


Thanks for the attention.
