Netfilter functions and structures..

[c_guy]

I'm trying to port a 2.2 kernel module to the new netfilter 2.4 code but I'm having some difficulty finding the definitions for some of the structs and function calls. I'm hoping someone knows where I can find some very specific information about the functions and macro's used and available in the new netfilter code. I have poured over the netfiler website and cannot find the information I need. Looking for the definition of NIPQUAD, and IP_NF_ASSERT. Specifically. These would be a good start, and then I'll go from there..

Thanks for any help...

what do you mean by definition? what they do in english or what the code actually is?

if you just want the code, goto http://lxr.linux.no/
click "browse the code" at the top, goto identifier search, then enter whatever your looking for. it'll search the linux kernel code for the identifier and take you to the definition and/or places the identifer is used. in general, much quicker and more useful than grepping.

i checked for both the things you asked for, both come up as the first result.

Thanks a million, that's a great start, but I also need the 'what this does' in plain english. I can read the code, but that doesn't give me all the answers I need.

Any other suggestions...

i haven't personally looked much at the networking portion of the kernel so i can't tell you much about it from my own experiences. however, the two orielly books do have sections on networking.
