[ASL] errors to install route_check module

[Giuseppe C. <giu...@gm...>]

I searched to install the route_check module in my pc, I run ubuntu 10.04
kernel v2.6, when i prove to install the module and type the make command i
received some errors, I resolved more of there changed the path in MakeFile
but i could not install the route_check module because i received other
errors such as
error: invalid use of undefined type ‘struct nf_hook_ops’

I tried to install the module route_check in my pc, I ran 10.04 kernel
v2.6, when I try to install the module and I type the make command received
some errors, I fixed some errors by changing the path in makefile but I
could not install the form route_check because I received other errors as
error: invalid use of undefined type 'struct nf_hook_ops'

where is the problem?

Thanks!

Hi,

I'm french, I'd like to find a course in information management. I don't know very much the qualification types in Scotland. I have the equivalent of a three-year university degree and I'd like to have a short qualification (maybe in a part-time in order to work as information officer at the same time).
I know it's certainly too late to apply but are there any courses we could recommand me ?

Thank you
Regards,
Christelle C.

Re: [ASL] looking for wireless sniffer tools

[Vikas K. <ka...@co...>]

Try Kismet <http://www.kismetwireless.net>.
It puts the card in RFmon mode, and can detect and log every packet in 
range, even ones it cannot decode or are no on the same essid.
You can set it to cycle through various channels as well.

[ASL] Aslib IPv6 address compatible?

[ASL] (no subject)

[Vikas K. <ka...@co...>]

The route_check modules in ASL-a-0.5 is actually for aodv and is the same
as aodv-helper. The simple route-check is in ASL-0.11. The definition of
output_filter is unnecessary code, it is not needed at all. I will correc=
t
it.  route-check actually needs only one hook, and that is at the
NF_IP_POST_ROUTING.

It is very different from kernel-AODV. kernel-AODV is doing all the
forwarding in the kernel module, hence bypassing the kernel routing table
completely. ASL lets the kernel do the forwarding, and routing is in
user-space.  route_check is simply to log the usage times of the routes,
hence it does not need all the hooks which kernel-aodv needs.

If you have not already done so, please look at the MOBISYS paper on=20
http://aslib.sourceforge.net

I will also try to find out if the MS thesis you mention can be made
available.

[ASL] AODV doesn't receive Hello packets

[Dhaval M. <dha...@ya...>]

Hi Vikas,

I am running into a weird problem running AODV:

I currently have 2 laptops set up in ad hoc mode running AODV.  I start up aodvd on one of them and I can see that it is sending out hello packets approx every second.  Then I start aodvd on the 2nd laptop.  Both receive one hello packet sent by the other one, and then both of them go into this mode where they are both sending hello packets, but aren't receiving any.  When I do a netstat -ul, I see that the aodv port is open and that the receive queue is increasing.  That means that though both actually receive the hello packets sent on the socket/port, the code that is supposed to receive those packets isn't getting called, and hence the packets remain in the receive buffer of the OS.

I don't know if you've ever seen this before or not, but any insight would be helpful.

Thanks,
Dhaval

[ASL] Update on route_check.o problems

[Vikas K. <ka...@co...>]

	I spent the last few hours trying to debug route_check.o, and in
the process managed to irrepairably corrupt my filesystem. Before that I
could discover that the problem is essentially due to redefinition of some
netfilter symbols in newer kernel. Hence there are unresolved symbols and
null pointer dereferencing. 

	route_check.o works for stock 2.4.18 downloaded off 
http://www.kernel.org/pub/linux/kernel/v2.4/  After some effort it could 
be made to work with later kernels. But then it may not work with 2.4.18. 
In general it appears messy to keep the module uptodate with kernel 
versions.

	I now believe that ASL should do away with route_check.o and
become truly and completely a userspace library. Let me present my case.
route_check.o is there to duplicate route caching information which the
kernel already maintains but does not output to /proc/net/rt_cache.
route_check.o was written since we did not want to change the kernel
source AT ALL. See section 4.1.2 of the paper:
http://aslib.sourceforge.net/papers/HTML-paper-327/index.html


	It turns out there is another way to get the last_use_time out of 
the kernel, and that is through a NETLINK socket. The popular tool 
iproute2 does that. For example try the command: 

ip -s -s route list cache

What we want is the "age field". The information is there in the output,
we could put it to a file and grep it or something. But thats ugly. So
what ASL really should do is open a netlink socket to the kernel and read
this route cache information. This would have to be done in the function 
query_route_idle_time() in libASL/api.c.  This is in essence a replication 
of part of what iproute2 does.

The source of iproute2 is here:
(http://www-courses.cs.uiuc.edu/~cs397hou/iproute2-2.4.7-now-ss010824.tar.gz)
The relevant function is rtnl_rtcache_request(struct rtnl_handle *rth, int 
family) in ip/iproute.c and the file lib/libnetlink.c. So one needs to 
carefully look into these two files and incorporate that functionality in 
query_route_idle_time().


	
Effect on AODV.
--------------

AODV uses route_check.o in a more complicated way through the function  
query_route_idle_time_aodv(addr_t k,  int destination_flag) defined in 
ASL-a. This is to support a seemingly redundant subte optimization, see 
section 5.1.3 of the above paper. We could do away with it at the risk of 
not completely complying with the AODV draft. In anycase, 
query_route_idle_time_aodv() can also be modified to use all the 
information it needs from the kernel cache.


I have outlined my thoughts and possible options. I would appreciate input 
from the list.

The changes I propose are straightforward but tedious. Rolling out a well
tested new version may be 3-4 days of hard work. Unfortunately I am really
caught up in other work, and cant afford to do this for another 2 weeks or
so at least. In the unlikely event that someone on the list feels 
motivated, I would be glad to help. Inputs on the proposed changes are 
appreciated anyways.


Thanks

I dont have a redhat 8 system now, but I downloaded the kernel from this 
site and this one works.
http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.18.tar.bz2 

I am debugging the module for higher kernels, right now.

[ASL] Kernel panics!!!

[Dhaval M. <dha...@ya...>]

Hi Vikas,
 
I have redhat 8.  The versions are as follows:
gcc - 3.2
autoconf - 2.53
automake  - 1.6.3

I compiled it and it worked this time around (it didn't give me any such errors).
 
But now, after making aodvd when i try to insert route_check.o it freezes.  It insmod'ed route_check.o BEFORE I made aodvd.
 
I'm clueless as to why it's behaving like this. 
 
I'd appreciate it if you could please look into this.
 
Thanks a bunch,
Dhaval

Hi Vikas,

I am trying to install ASL, and while making it I get the error:

configure.in:56: error: do not use LIBOBJS directly, use AC_LIBOBJ (see section
`AC_LIBOBJ vs. LIBOBJS'
make: *** [configure] Error 1

Could you please tell me what I need to do to fix this?

If you are talking about the error in select: "Interrupted System call", 
it is normal. It occurs because signals, in this case SIGALRM, cause 
select to break, and it returns -1. We simple call select again, and its 
not a problem. One could use pselect() to mask certain signals but often 
those signals are necessary and cannot be masked.

It still works with versions up to 2.4.18 only. I have'nt spent too much
time on it, but could'nt figure out what has changed in 2.4.19 thats
causing a panic. I'll have to use uml to complete the debugging..

Re: [ASL] Error in select

[Armen B. <ar...@cs...>]

Hi Dhaval,

It's been a very long time since I've looked at my ad-hoc stuff...so I=20=

don't recall exactly what the problem was.

But looking at the source code in aodv.cc, the call to select() does=20
not seem correct.  select() needs a struct timeval * as its last=20
argument, so I think you should declare a struct timeval timeout , and=20=

initialize the timeout.tv_sec and timeout.tv_usec fields of, and then=20
pass this pointer to this to select().  The existing aodv.cc just=20
passes a NULL pointer, which select() might be complaining about (and=20
thus returning < 0).

That may be the problem. Let me (or this list) know.  When I get back=20
into this work, I'll look at it some more.

I also plan to take a crack at figuring out why route_check doesn't=20
want to work in kernels > 2.4.18, now that I've been learning a bit=20
about linux kernel internals.  Ah, the todo list keeps getting bigger.=20=

:)

Hope this helps,
