>Description:
A patch to create dynamic sysctl nodes at runtime
>How-To-Repeat:
N/A
>Fix:
The following code (and corresponding code for other data types supported
by sysctl) needs to go into /usr/src/sys/kern/kern_sysctl.c
void
sysctl_register_long(struct sysctl_oid_list *parent, int number, char *name,
int access, long *ptr, struct sysctl_oid *oidp)
{
oidp->oid_parent = parent;
SLIST_NEXT(oidp, oid_link) = NULL;
oidp->oid_number = number;
oidp->oid_name = name;
oidp->oid_handler = sysctl_handle_long;
oidp->oid_kind = CTLTYPE_INT | access;
oidp->oid_arg1 = (void *) ptr;
oidp->oid_arg2 = 0;
oidp->oid_fmt = "L";
/* Register this oid */
sysctl_register_oid(oidp);
}
