Hello,

I faced a problem passing a string argument to module as parameter of
'insmod'. Let's say, I have the following bit of code (kernel 2.4.18):

#define __KERNEL__
#define MODULE

#include
#include
#include

static char mac[18];

MODULE_PARM(mac, "c18");

static int __init probe_init(void)
{
printk(KERN_ALERT "mac=, %18s\n", mac);
return 0;
}

static void __exit probe_exit(void)
{
/* unregister facilities */
}

module_init(probe_init);
module_exit(probe_exit);
....

I compiled the module with the following flags:

#gcc -W -Wall -I/usr/src/linux-2.4.18-14/include/ -c probe.c -o probe.o

and load it:

#insmod probe.o mac=00:00:11:11:22:22
probe.o: string too long for mac (max 17)

Where is the problem? I guess 18 is more then enough for storing MAC address
and terminating NULL.

Thanks in advance for help.
