2010-04-01netlabel: Fix several rcu_dereference() calls used without RCU read locksPaul Moore2-57/+37
The recent changes to add RCU lock verification to rcu_dereference() calls caught out a problem with netlbl_unlhsh_hash(), see below. =================================================== [ INFO: suspicious rcu_dereference_check() usage. ] --------------------------------------------------- net/netlabel/netlabel_unlabeled.c:246 invoked rcu_dereference_check() without protection!

2010-03-30iwlwifi: clear unattended interrupts in taskletShanyu Zhao1-1/+9
Previously in interrupt handling tasklet, iwlwifi driver only clear/ack those interrupts that are enabled by the driver through inta_mask. If the hardware generates unattended interrupts, driver will not ack them, defeating the interrupt coalescing feature. This results in high number of interrupts per second and high CPU utilization. This patch addresses this issue by acking those unattended interrupts in the tasklet. Local test showed an order of magnitude improvement in terms of the number of interrupts without sacrificing networking throughput. This is a workaround for hardware issue.

2010-03-30mac80211: move netdev queue enabling to correct spotJohannes Berg2-6/+12
"mac80211: fix skb buffering issue" still left a race between enabling the hardware queues and the virtual interface queues. In hindsight it's totally obvious that enabling the netdev queues for a hardware queue when the hardware queue is enabled is wrong, because it could well possible that we can fill the hw queue with packets we already have pending. Thus, we must only enable the netdev queues once all the pending packets have been processed and sent off to the device. In testing, I haven't been able to trigger this race condition, but it's clearly there, possibly only when aggregation is being enabled.

2010-03-29r8169: offical fix for CVE-2009-4537 (overlength frame DMAs)Neil Horman1-5/+24
Official patch to fix the r8169 frame length check error. Based on this initial thread: http://marc.info/?l=linux-netdev&m=126202972828626&w=1 This is the official patch to fix the frame length problems in the r8169 driver. As noted in the previous thread, while this patch incurs a performance hit on the driver, its possible to improve performance dynamically by updating the mtu and rx_copybreak values at runtime to return performance to what it was for those NICS which are unaffected by the ideosyncracy (if there are any). Summary: A while back Eric submitted a patch for r8169 in which the proper allocated frame size was written to RXMaxSize to prevent the NIC from dmaing too much data. This was done in commit fdd7b4c3302c93f6833e338903ea77245eb510b4. A long time prior to that however, Francois posted 126fa4b9ca5d9d7cb7d46f779ad3bd3631ca387c, which expiclitly disabled the MaxSize setting due to the fact that the hardware behaved in odd ways when overlong frames were received on NIC's supported by this driver. This was mentioned in a security conference recently: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html It seems that if we can't enable frame size filtering, then, as Eric correctly noticed, we can find ourselves DMA-ing too much data to a buffer, causing corruption. As a result is seems that we are forced to allocate a frame which is ready to handle a maximally sized receive. This obviously has performance issues with it, so to mitigate that issue, this patch does two things: 1) Raises the copybreak value to the frame allocation size, which should force appropriately sized packets to get allocated on rx, rather than a full new 16k buffer. 2) This patch only disables frame filtering initially (i.e., during the NIC open), changing the MTU results in ring buffer allocation of a size in relation to the new mtu (along with a warning indicating that this is dangerous). Because of item (2), individuals who can't cope with the performance hit (or can otherwise filter frames to prevent the bug), or who have hardware they are sure is unaffected by this issue, can manually lower the copybreak and reset the mtu such that performance is restored easily.

2010-03-27bonding: fix broken multicast with round-robin modeAndy Gospodarek1-8/+32
Round-robin (mode 0) does nothing to ensure that any multicast traffic originally destined for the host will continue to arrive at the host when the link that sent the IGMP join or membership report goes down. One of the benefits of absolute round-robin transmit. Keeping track of subscribed multicast groups for each slave did not seem like a good use of resources, so I decided to simply send on the curr_active slave of the bond (typically the first enslaved device that is up). This makes failover management simple as IGMP membership reports only need to be sent when the curr_active_slave changes. I tested this patch and it appears to work as expected.

Previously the driver tweaked txqueuelen to avoid false Tx hang reports seen at half duplex. This had the effect of overriding user set values on link change/reset. Testing shows that adjusting only the timeout factor is sufficient to prevent Tx hang reports at half duplex. This patch removes all instances of tx_queue_len in the driver.

2010-03-26ipv4: Restart rt_intern_hash after emergency rebuild (v2)Pavel Emelyanov1-6/+11
The the rebuild changes the genid which in turn is used at the hash calculation. Thus if we don't restart and go on with inserting the rt will happen in wrong chain.
