Hi all,

Well, i have written a (netfilter) loadable = kernel module=20 for filtering various packets. I pass these packets from kernel=20 space to user space using libipq.

I also have a user process thas loads and = unloads=20 this loadable kernel module using the commands:

system("insmod kernel_module.o")

system("rmmod kernel_module") = respectively.

I'd like to pass parameters to the = loadable module,=20 hence having a more flexible user process.

So, instead of using the command = system("insmod=20 kernel_module.o"),

i'd like to use: system("insmod = kernel_module.o=20 <param1> <param2>...<param n>")

, hence passing command line parameters to my = loadable=20 module.

Do you know if it is possible?

Thanks

You definitely want the know about the MODULE_PARM() macro. Get more information by reading an existing module like for example: grep ^MODULE_ /usr/src/linux/drivers/net/3c59x.c Best regards, Roberto Nibali, ratz -- echo '[q]sa[ln0=aln256%Pln256/snlbx]sb3135071790101768542287578439snlbxq' | dc From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joel Newkirk Subject: Re: About loadable kernel modules Date: Mon, 7 Oct 2002 21:06:51 -0400 Sender: netfilter-admin@lists.netfilter.org Message-ID: <200210072106.51708.netfilter@newkirk.us> References: <001001c26a3e$1900bab0$c5327d9e@alex> Reply-To: netfilter@newkirk.us Mime-Version: 1.0 Content-Transfer-Encoding: quoted-printable Return-path: In-Reply-To: <001001c26a3e$1900bab0$c5327d9e@alex> Errors-To: netfilter-admin@lists.netfilter.org List-Help: List-Post: List-Subscribe: , List-Id: List-Unsubscribe: , List-Archive: Content-Type: text/plain; charset="us-ascii" To: Alexandros Fragkiadakis , netfilter@lists.netfilter.org On Wednesday 02 October 2002 02:04 pm, Alexandros Fragkiadakis wrote: > Hi all, > > Well, i have written a (netfilter) loadable kernel module for filtering > various packets.

Probably execl(*command,*arg1,*arg2,*arg3...,null) will do what you want. j
