So, i make everything successfully, it creates q_xcp.so and copies
it to /usr/lib and sch_xcp.o which it copies to /lib/modules/... so
then I "insmod sch_xcp" and i see in dmesg: "XCP qdisc module
loaded."
I then try: "tc qdisc add dev eth0 root xcp capacity 10Mbit limit
500" and get: "Unknown qdisc "xcp", hence option "capacity" is
unparsable"
So then I read the INSTALL further to find some sort of solution
and it mentions: This again assumes "tc" version is 2.4.7. If your
"tc" is a different version, download the iproute2 source code, and
edit Makefile to point "TC_INCLUDE" to "-I/iproute2/include
-I/iproute2/tc"
So, i did that, and i recompiled the q_xcp.so: lanthanum-ini
src-1.0.1 # make q_xcp.so cc -O2 -fPIC
-I/var/tmp/portage/iproute2-2.6.11.20050310-r1/work/iproute2-2.6.11

/tc_ include -o q_xcp.o -c q_xcp.c ld -shared -o q_xcp.so q_xcp.o rm
-f q_xcp.o
But i still get the same error so then my very final last
effort was to move q_xcp.c to my iproute2 source code tc/ directory
and added this to the makefile: TCMODULES += q_xcp.o
Then I compiled tc, and i check tc to see if the xcp qdisc
functions were loaded: lanthanum-ini tc # nm tc | grep xcp 080531ec
t xcp_parse_opt 080533e0 t xcp_print_opt 08053426 t xcp_print_xstats
08070cc0 D xcp_util
And finally: lanthanum-ini tc # ./tc qdisc add dev ath0 root xcp
capacity 54Mbit limit 500 Unknown qdisc "xcp", hence option
"capacity" is unparsable
I have no clue :( I figured that putting the .so into /usr/lib

I think what I'm most confused about this pkt_sched.h thing is that the code
works with version 2.4.7 of iproute2 ... in 2.4.7 of iproute2 there is no
pkt_sched.h anywhere to be found in the source code.
However in the newest version of iproute2 which I am trying to get this
functionality to work in, there is a pkt_sched.h
My last observation, is that in q_xcp.h it includes pkt_sched_xcp.h which has:
struct tc_xcp_qopt
{
__u32 first_param;
__u32 second_param;
};
So I am assuming i need to add something like the enum thing to pkt_sched.h in
the new iproute2 source... however what are the proper names I need to use in
the enum? I don't expect you to know the names, however, what do i match them
with?
Thanks!
George

George,
Then you probably need to revert to an iproute2 source that included
xcp. In pkt_sched.h you need a struct that defines the parameters xcp
can accept:
enum
{
TCA_XCP_PARM1,
TCA_XCP_PARM2,
TCA_XCP_PARM3,
};
and in ~/tc/Makefile you need TCMODULES += q_xcp.o

George,
Please show us

There shouldn't be anything there the author wishes to keep private.

Re: [LARTC] created new q_disc, inserted module, tc tells me unknown qdisc
Hey Tim, I will take a look at that routine, it just seems no matter what I do I cannot seem to find out why it determines it does not have xcp qdisc support. I will look deeper into it. I am not sure if it has been released to the public yet. I am using Yongguang Zhang and Tom Henderson's Linux implementation. I am also not sure it is the same packet formated as the ISI FreeBSD implementation. Tom pre-released it to me for my research on the topic, I think I will ask him if it is public yet, because if so I think I could find help a lot easier :) I will get back to you with what I find. Thanks! George Tim Shepard wrote: To debug this you'll probably want to have a look at the get_qdisc_kind() routine in tc/tc.c in the iproute sources and understand how it uses dlopen() to find the routines to parse the arguments to the various different qdisc implementations..

[LARTC] created new q_disc, inserted module, tc tells me unknown qdisc
Hi,
I am trying to install a proprietary qdisc made for research, it is not
publically released yet, however its been used several times so i know it works.
The files included are:
q_xcp.c:
static int xcp_parse_opt()
static int xcp_print_opt()
static int xcp_print_xstats()
struct qdisc_util xcp_util = { "NULL", "xcp" . };
sch_xcp.c:
static int xcp_enqueue()
static int xcp_requeue()
static struct sk_buff * xcp_dequeue()
struct Qdisc_ops xcp_qdisc_ops ={ NULL,NULL,"xcp", };
printk(KERN_INFO "XCP qdisc module loaded.\n");
return register_qdisc(&xcp_qdisc_ops);
So, i make everything successfully, it creates q_xcp.so and copies it to
/usr/lib and sch_xcp.o which it copies to /lib/modules/... so then I "insmod
sch_xcp" and i see in dmesg:
"XCP qdisc module loaded."
I then try:
"tc qdisc add dev eth0 root xcp capacity 10Mbit limit 500" and get:
"Unknown qdisc "xcp", hence option "capacity" is unparsable"
So then I read the INSTALL further to find some sort of solution and it
mentions:
This again assumes "tc" version is 2.4.7. If your "tc" is a different
version, download the iproute2 source code, and edit Makefile to
point "TC_INCLUDE" to "-I/iproute2/include -I/iproute2/tc"
So, i did that, and i recompiled the q_xcp.so:
lanthanum-ini src-1.0.1 # make q_xcp.so
cc -O2 -fPIC
-I/var/tmp/portage/iproute2-2.6.11.20050310-r1/work/iproute2-2.6.11/include/
-I/var/tmp/portage/iproute2-2.6.11.20050310-r1/work/iproute2-2.6.11/tc_include
-o q_xcp.o -c q_xcp.c
ld -shared -o q_xcp.so q_xcp.o
rm -f q_xcp.o
But i still get the same error so then my very final last effort was to
move q_xcp.c to my iproute2 source code tc/ directory and added this to the
makefile:
TCMODULES += q_xcp.o
Then I compiled tc, and i check tc to see if the xcp qdisc functions were
loaded:
lanthanum-ini tc # nm tc | grep xcp
080531ec t xcp_parse_opt
080533e0 t xcp_print_opt
08053426 t xcp_print_xstats
08070cc0 D xcp_util
And finally:
lanthanum-ini tc # ./tc qdisc add dev ath0 root xcp capacity 54Mbit limit 500
Unknown qdisc "xcp", hence option "capacity" is unparsable
I have no clue :( I figured that putting the .so into /usr/lib would have been
