Hello, I'm writing a LKM that uses netfilter hooks. I thought that netfilter hooks were run in softirq context. So when using spinlocks in the hooks I use plain spin_lock and in any process context code e.g. proc I use spin_lock_bh. However my code occasionally deadlocks with this single lock. If the hooks were running in softirq context this wouldn't occur because softirq's don't preemept each other on the same processor. So now I'm wondering if my original softirq assumption was incorrect. Can a hook be called from NON softirq context? thanks in advance Iain -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
