2010-06-05iwl3945: enable stuck queue detection on 3945Reinette Chatre1-0/+1
We learn from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1834 and https://bugzilla.redhat.com/show_bug.cgi?id=589777 that 3945 can also suffer from a stuck command queue.

2010-06-04rps: tcp: fix rps_sock_flow_table table updatesEric Dumazet1-3/+4
I believe a moderate SYN flood attack can corrupt RFS flow table (rps_sock_flow_table), making RPS/RFS much less effective. Even in a normal situation, server handling short lived sessions suffer from bad steering for the first data packet of a session, if another SYN packet is received for another session. We do following action in tcp_v4_rcv() : sock_rps_save_rxhash(sk, skb->rxhash); We should _not_ do this if sk is a LISTEN socket, as about each packet received on a LISTEN socket has a different rxhash than previous one. -> RPS_NO_CPU markers are spread all over rps_sock_flow_table. Also, it makes sense to protect sk->rxhash field changes with socket lock (We currently can change it even if user thread owns the lock and might use rxhash) This patch moves sock_rps_save_rxhash() to a sock locked section, and only for non LISTEN sockets.

2010-06-04net: check for refcount if pop a stacked dst_entrySteffen Klassert2-5/+5
xfrm triggers a warning if dst_pop() drops a refcount on a noref dst. This patch changes dst_pop() to skb_dst_pop(). skb_dst_pop() drops the refcnt only on a refcounted dst. Also we don't clone the child dst_entry, so it is not refcounted and we can use skb_dst_set_noref() in xfrm_output_one().

Commit 56d1de0a21db28e41741cfa0a66e18bc8d920554, "ath5k: clean up filter flags setting" introduced a regression in monitor mode such that the promisc filter flag would get lost. Although we set the promisc flag when it changed, we did not preserve it across subsequent calls to configure_filter. This patch restores the original functionality.

2010-06-04mac80211: process station blockack action frames from workJohannes Berg2-7/+48
Processing an association response could take a bit of time while we set up the hardware etc. During that time, the AP might already send a blockack request. If this happens very quickly on a fairly slow machine, we can end up processing the blockack request before the association processing has finished. Since the blockack processing cannot sleep right now, we also cannot make it wait in the driver. As a result, sometimes on slow machines the iwlagn driver gets totally confused, and no traffic can pass when the aggregation setup was done before the assoc setup completed. I'm working on a proper fix for this, which involves queuing all blockack category action frames from a work struct, and also allowing the ampdu_action driver callback to sleep, which will generally clean up the code and make things easier. However, this is a very involved and complex change. To fix the problem at hand in a way that can also be backported to stable, I've come up with this patch. Here, I simply process all aggregation action frames from the managed interface skb queue, which means their processing will be serialized with processing the association response, thereby fixing the problem.

2010-06-02korina: fix deadlock on RX FIFO overrunPhil Sutter1-14/+13
By calling korina_restart(), the IRQ handler tries to disable the interrupt it's currently serving. This leads to a deadlock since disable_irq() waits for any running IRQ handlers to finish before returning. This patch addresses the issue by turning korina_restart() into a workqueue task, which is then scheduled when needed. Reproducing the deadlock is easily done using e.g. GNU netcat to send large amounts of UDP data to the host running this driver. Note that the same problem (and fix) applies to TX FIFO underruns, but apparently these are less easy to trigger. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: David S.

2010-06-02net: fix conflict between null_or_orig and null_or_bondJohn Fastabend1-4/+4
If a skb is received on an inactive bond that does not meet the special cases checked for by skb_bond_should_drop it should only be delivered to exact matches as the comment in netif_receive_skb() says. However because null_or_bond could also be null this is not always true. This patch renames null_or_bond to orig_or_bond and initializes it to orig_dev. This keeps the intent of null_or_bond to pass frames received on VLAN interfaces stacked on bonding interfaces without invalidating the statement for null_or_orig.
