[PATCH] [TRY2] Use nfmark as a key in u32 classifier
Hello!
This is the try number two.
What was changed:
- Added selectable choice in Kconfig file (thanks Jamal!)
- Don''t abuse tc_u32_sel to not break backward compatibility (thanks
Patrick!).
Stephen, do you have any comments on iproute2 part? I know it''s not
perfect but this is the best way, I think. "u32 match mark vvvv mmmm" it''s
intuitive but breaks a little the levels, "u32 mark vvvv mmmm&qu...

match mark problem still resists
...oblem
be related to the only match inside ''parse_selector'' that is treated
differently from other matches?
All except ''mark'' is parsed like parse_xxxx(&argc, &argv, sel, ..) and mark is
parsed parse_mark(&argc, &argv, n,..) where sel is a struct tc_u32_sel and n is
a struct nlmsghdr.
I should say that this deserves at least an "You idiot, you are using it the
wrong way. Do like this and stop bothering me!" answer.
Sorry my tempestuous attitude.

offset mask usage in u32 filter
....ittc.ku.edu/howto/node48.html
I could find no explanation of this usage in LARTC,
and specifically, Section 12.4 on Hashing filters does
not use it. Searches of the mailing list did not
yield an answer. Review of tc code in f_u32.c showed
that in parse_offset() the arguments were assembled
into tc_u32_sel structure fields and passed into the
kernel. However, I could not figure out what the
intent was in cls_u32.c for these fields.
I would much appreciate an explanation or pointers to
information.

i just know the struct
struct tc_u32_key
{
__u32 mask;
__u32 val;
int off;
int offmask;
};
struct tc_u32_sel
{
unsigned char flags;
unsigned char offshift;
unsigned char nkeys;
__u16 offmask;
__u16 off;
short offoff;
short hoff;
__u32 hmask;

};
but i don't know how to fill it ,

[PATCH] Use nfmark as a key for u32 classifier
Hello!
I am glad to announce a patch for u32 to allow matches on nfmark.
The patch is non intrusive (few lines).
Why I did this? Because fw classifier cannot be used together with u32.
For example, now, you cannot match a mark of 0x90 and a destination
port of 80. I know you can do it with iptables to do the marking, but if
you use Jamal actions to apply mark to policed packets, you need
