I'm taking a stab at porting Darren Reed's ipfilter to 2.2 and
have run into a snag with some changed macros in the LKM stuff.
Could someone a bit more familiar with LKM explain the differences?
------------------------------------------------------------------------
>From 2.1.6.1:
/usr/include/sys/lkm.h
#define MOD_DEV(name,devtype,devslot,devp) \
static struct lkm_dev _module = { \
LM_DEV, \
LKM_VERSION, \
name, \
devslot, \
devtype, \
(void *)devp \
};
------------------------------------------------------------------------
>From 2.2:
#define MOD_DEV(name,devtype,devslot,devp) \
MOD_DECL(name); \
static struct lkm_dev name ## _module = { \
LM_DEV, \
LKM_VERSION, \
#name ## "_mod", \
devslot, \
devtype, \
(void *)devp \
}
#define MOD_DECL(name) \
static int name ## _load __P((struct lkm_table *lkmtp, int cmd)); \
static int name ## _unload __P((struct lkm_table *lkmtp, int cmd)); \
int name ## _mod __P((struct lkm_table *lkmtp, int cmd, int ver)) \
------------------------------------------------------------------------
It's use in ipfilter:
line 122: MOD_DEV(IPL_VERSION, LM_DT_CHAR, -1, &ipldevsw);
