2012-05-17drop_monitor: convert to modular buildingNeil Horman2-3/+45
When I first wrote drop monitor I wrote it to just build monolithically. There is no reason it can't be built modularly as well, so lets give it that flexibiity. I've tested this by building it as both a module and monolithically, and it seems to work quite well Change notes: v2) * fixed for_each_present_cpu loops to be more correct as per Eric D. * Converted exit path failures to BUG_ON as per Ben H. v3) * Converted del_timer to del_timer_sync to close race noted by Ben H.

2012-05-17net: netdev_alloc_skb() use build_skb()Eric Dumazet1-1/+31
netdev_alloc_skb() is used by networks driver in their RX path to allocate an skb to receive an incoming frame. With recent skb->head_frag infrastructure, it makes sense to change netdev_alloc_skb() to use build_skb() and a frag allocator. This permits a zero copy splice(socket->pipe), and better GRO or TCP coalescing. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-05-16fq_codel: should use qdisc backlog as thresholdEric Dumazet2-4/+5
codel_should_drop() logic allows a packet being not dropped if queue size is under max packet size. In fq_codel, we have two possible backlogs : The qdisc global one, and the flow local one. The meaningful one for codel_should_drop() should be the global backlog, not the per flow one, so that thin flows can have a non zero drop/mark probability.

It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited.
