Subject: Re: [v12 PATCH 2/3] NETFILTER module xt_hmark, new target for HASH
based fwmark
Hi Hans,
I have decided to take your patch and give it one spin today.
Please, find it attached. The main things I've done are:
* splitting the code into smaller functions, thus, it becomes more
maintainable.
* try to put common code into functions, eg. the layer 4 protocol
parsing to obtain the ports is the same for both IPv4 and IPv6.
* adding the hmark_tuple abstraction, cleaner than using several
variables to set the address, ports, and so on. Thus, we only pass
one single pointer to it.
* I have removed most of the comments, they bloat the file and most
information can be extracted by reading the code. I only left the
comments that clarify "strange" things.
Regarding ICMP traffic, I think we can use the ID field for the
hashing as well. Thus, we handle ICMP like other protocols.
Please, I'd appreciate if you can test and spot issues after my
rework. I have slightly tested here.
I may make some minor cleanup on it before submission but, in that
case, in that case, I'll post the patch. I would not expect more major
changes in it.
Let me know.
