Mostly they are null pointer dereferences due to uninitialized timer (qdisc watchdog) or double frees due to ->destroy cleaning up a second time. There's more information in each patch. I've tested these by either sending wrong attributes from user-spaces, no attributes or by simulating memory alloc failure where applicable. Also tried all of the qdiscs as a default qdisc. Most of these bugs were present before commit 87b60cfacf9f, I've tried to include proper fixes tags in each patch. I haven't included individual patch acks in the set, I'd appreciate it if you take another look and resend them. ==================== Acked-by: Jamal Hadi Salim Signed-off-by: David S.
