(usagi-users 02689) Re: Linux 2.6 radvd error

["Yang Hsiung" <yhsiung@xxxxxxxxx>]

Hi,

I figured out the error was coming from sys_sysctl() function
in kernel/sysctl.c. The calling function is in check_ip6_forwarding()
in the radvd.c.

The following code fragment was added to sysctl.c since 1.1.1.26.
Does anyone knows why the code was added in sys_sysctl()?

	if (tmp.nlen != 2 || copy_from_user(name, tmp.name, sizeof(name)) ||
	    name[0] != CTL_KERN || name[1] != KERN_VERSION) { 
		int i;
		printk(KERN_INFO "%s: numerical sysctl ", current->comm); 
		for (i = 0; i < tmp.nlen; i++) {
			int n;
			
			if (get_user(n, tmp.name+i)) {
				printk("? ");
			} else {
				printk("%d ", n);
			}
		}
		printk("is obsolete.\n");
	} 

Currently, I just blindly commented out the above code and I can start
the radvd successfully.

Hi,

I ran radvd under Linux 2.6 but failed with the following error
logged in /var/log/messages:

kernel: radvd: numerical sysctl 3 12 16 -2 1 is obosolete.


The same /etc/radvd.conf was running okay in the Linux 2.4.20 kernel.

Any idea?
