Linux version RFC compliance list (where?)
Could you tell me how to figure out which RFCs are supported by a given version of Linux?
If possible, I'd like the answer to this general question, but in case there is no answer, here's my specific need. I have linux version 2.6.16.18, I'm an IPv6 developer (kinda new at it). I want to know whether, for example, RFC 1981 is supported (this is the IPv6 version of Path MTU Discovery). I actually have a list of RFCs I want to know about. I've looked at the IPv6 HOW-TO, I've searched through this site, I've googled the web in general, I've looked at the Linux Documentation Project site, and I can't seem to find a comprehensive list of which RFCs are supported in which versions of linux. I know it's got to be out there somewhere. It will take me a long time if I need to read the kernel code to figure out whether, for example, 2.6.16.18 supports the older version RFC 2463 ICMPv6 or whether it supports the newer RFC 4443 ICMPv6. Well, actually, that one is probably pretty easy to answer because 4443's date is later than 2.6.16.18's date. But you see what I mean. So, I'm really asking for a pointer to a doc somewhere? Or a site that lists all the RFCs in Linux, to search? Please? and thank you for any help you can provide, even partial. Just in case there's actually no comprehensive doc but you have personal knowledge of a particular RFC compliance, here's the list of RFCs I'm interested in: RFC 1981 Path MTU Discovery RFC 3315 DHCPv6 (I'm pretty sure the answer here is NOT in linux yet but you can get software from fedorahosted.org that you can install.) RFC 2710 Multicast Listener Discovery RFC 4193 Unique IPv6 Local Address RFC 4007 IPv6 Scoped Address Architecture Here are ones I'm pretty sure ARE in linux 2.6.16.18 -- I am just assuming that all of the following are supported, based on the chart in the IPv6 HOW-TO, although it's a bit of a stretch because they are NOT listed by number: 2460: IPv6 2461: Neighbor Discovery 2462: IPv6 over Ethernet 2463: ICMPv6 (probably not the newer 4443) 3513: IPv6 Addressing Architecture (probably not the newer 4291) Thanks again for any help you can give me to figure out HOW to figure this out!

About where and how, not what.

Thank you, unSpawn, the hint to search only the site kernel.org was very helpful.
It would be a foolproof search method if the developers always mentioned the RFC they were implementing, but apparently they don't. It is still a hit-or-miss guess after a fair amount of code-reading as to when the RFC was actually implemented. The Path MTU Discovery is a good example. The RFC 1981 is mentioned in a comment on a bugfix in version 2.6.16-rc1, but the code was in earlier versions and never mentioned RFC 1981. Nonetheless, I really do appreciate the help; with it I was able to find out a lot more info. I am fairly new to open-source codebases and I just need to readjust my expectations for documentation (as in, "the code is the documentation -- if you want to know whether a particular RFC is implemented, first read the RFC then read the code" :-) ) |
Come to think of it there also are a few consortia that do Linux (kernel) compliance tests. Maybe those published results or the tests themselves could help you assess if something is implemented or not.
