713b3c9 Jesse Brandeburg 02 February 2011, 10:19:50 UTC e1000e: flush all writebacks before unload The driver was not flushing all writebacks before unloading, possibly causing memory to be written by the hardware after the driver had reinitialized the rings. This adds missing functionality to flush any pending writebacks and is called in all spots where descriptors should be completed before the driver begins processing.

There was a bug in my commit c978e7bb77dfd2cd3d1f547fa4e395cfe47f02b2 ("hisax: Fix unchecked alloc_skb() return.") One of the l2->flag checks is wrong. Even worse it turns out I'm duplicating an existing function, so use that instead. Reported-by: Milton Miller <miltonm@bga.com> Signed-off-by: David S.

d11327a Ian Campbell 11 February 2011, 07:44:16 UTC arp_notify: unconditionally send gratuitous ARP for NETDEV_NOTIFY_PEERS. NETDEV_NOTIFY_PEER is an explicit request by the driver to send a link notification while NETDEV_UP/NETDEV_CHANGEADDR generate link notifications as a sort of side effect. In the later cases the sysctl option is present because link notification events can have undesired effects e.g. if the link is flapping. I don't think this applies in the case of an explicit request from a driver. This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we could add a new sysctl for this case which defaults to on. This change causes Xen post-migration ARP notifications (which cause switches to relearn their MAC tables etc) to be sent by default.

7e9c262 Casey Leedom 14 February 2011, 12:56:24 UTC cxgb4vf: Quiesce Virtual Interfaces on shutdown ... When a Virtual Machine is rebooted, KVM currently fails to issue a Function Level Reset against any "Attached PCI Devices" (AKA "PCI Passthrough"). In addition to leaving the attached device in a random state in the next booted kernel (which sort of violates the entire idea of a reboot reseting hardware state), this leaves our peer thinking that the link is still up. (Note that a bug has been filed with the KVM folks, #25332, but there's been no response on that as of yet.) So, we add a "->shutdown()" method for the Virtual Function PCI Device to handle administrative shutdowns like a reboot. Signed-off-by: Casey Leedom <leedom@chelsio.com> Signed-off-by: David S.

98200ec Toshiharu Okada 13 February 2011, 22:51:54 UTC pch_gbe: Fix the MAC Address load issue. With the specification of hardware, the processing at the time of driver starting was modified. This device write automatically the MAC address read from serial ROM into a MAC Adress1A/1B register at the time of power on reset. However, when stable clock is not supplied, the writing of MAC Adress1A/1B register may not be completed. In this case, it is necessary to load MAC address to MAC Address1A/1B register by the MAC Address1 load register. This patch always does the above processing, in order not to be dependent on system environment. Signed-off-by: Toshiharu Okada <toshiharu-linux@dsn.okisemi.com> Signed-off-by: David S.

da1ab3e Jesper Juhl 13 February 2011, 10:49:32 UTC ATM, Solos PCI ADSL2+: Don't deref NULL pointer if net_ratelimit() and alloc_skb() interact badly. If alloc_skb() fails to allocate memory and returns NULL then we want to return -ENOMEM from drivers/atm/solos-pci.c::popen() regardless of the value of net_ratelimit(). The way the code is today, we may not return if net_ratelimit() returns 0, then we'll proceed to pass a NULL pointer to skb_put() which will blow up in our face. This patch ensures that we always return -ENOMEM on alloc_skb() failure and only let the dev_warn() be controlled by the value of net_ratelimit().

5b89db0 Jesper Juhl 13 February 2011, 11:15:35 UTC Net, USB, Option, hso: Do not dereference NULL pointer In drivers/net/usb/hso.c::hso_create_bulk_serial_device() we have this code: ... serial = kzalloc(sizeof(*serial), GFP_KERNEL); if (!serial) goto exit; ... exit: hso_free_tiomget(serial); ... hso_free_tiomget() directly dereferences its argument, which in the example above is a NULL pointer, ouch. I could just add a 'if (serial)' test at the 'exit' label, but since most freeing functions in the kernel accept NULL pointers (and it seems like this was also assumed here) I opted to instead change 'hso_free_tiomget()' so that it is safe to call it with a NULL argument. I also modified the function to get rid of a pointles conditional before the call to 'usb_free_urb()' since that function already tests for NULL itself - besides fixing the NULL deref this change also buys us a few bytes in size.

8a87017 Herbert Xu 12 February 2011, 09:05:42 UTC bridge: Replace mp->mglist hlist with a bool As it turns out we never need to walk through the list of multicast groups subscribed by the bridge interface itself (the only time we'd want to do that is when we shut down the bridge, in which case we simply walk through all multicast groups), we don't really need to keep an hlist for mp->mglist. This means that we can replace it with just a single bit to indicate whether the bridge interface is subscribed to a group.

24f9cdc Herbert Xu 11 February 2011, 12:42:07 UTC bridge: Fix timer typo that may render snooping less effective In a couple of spots where we are supposed to modify the port group timer (p->timer) we instead modify the bridge interface group timer (mp->timer). The effect of this is mostly harmless. However, it can cause port subscriptions to be longer than they should be, thus making snooping less effective.

6b0d6a9 Herbert Xu 11 February 2011, 12:36:55 UTC bridge: Fix mglist corruption that leads to memory corruption The list mp->mglist is used to indicate whether a multicast group is active on the bridge interface itself as opposed to one of the constituent interfaces in the bridge. Unfortunately the operation that adds the mp->mglist node to the list neglected to check whether it has already been added. This leads to list corruption in the form of nodes pointing to itself. Normally this would be quite obvious as it would cause an infinite loop when walking the list. However, as this list is never actually walked (which means that we don't really need it, I'll get rid of it in a subsequent patch), this instead is hidden until we perform a delete operation on the affected nodes. As the same node may now be pointed to by more than one node, the delete operations can then cause modification of freed memory. This was observed in practice to cause corruption in 512-byte slabs, most commonly leading to crashes in jbd2. Thanks to Josef Bacik for pointing me in the right direction.

For unknown reason, sometimes after hw scanning, device is not able to receive frames at high rate. Since plcp health check may request hw scan to "reset radio", performance problem start to be observable after update kernel to .35, where plcp check was introduced. Bug reporter confirmed that removing plcp check fixed problem for him.

In this situation, the TCP tracking code destroys the existing conntrack to start a new clean session. [DESTROY] tcp 6 src=192.168.0.2 dst=192.168.1.2 sport=38925 dport=8000 src=192.168.1.2 dst=192.168.1.100 sport=8000 dport=38925 [ASSURED] [NEW] tcp 6 120 SYN_SENT src=192.168.0.2 dst=192.168.1.2 sport=38925 dport=8000 [UNREPLIED] src=192.168.1.2 dst=192.168.1.100 sport=8000 dport=38925 However, this is a problem for the iptables' CT target event filtering which will not work in this case since the conntrack template will not be there for the new session. To fix this, we reassign the conntrack template to the packet if we return NF_REPEAT.

8d3bdbd David S. Miller 08 February 2011, 23:02:50 UTC net: Fix lockdep regression caused by initializing netdev queues too early. In commit aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress queue") we moved the allocation and lock initialization of the queues into alloc_netdev_mq() since register_netdevice() is way too late. The problem is that dev->type is not setup until the setup() callback is invoked by alloc_netdev_mq(), and the dev->type is what determines the lockdep class to use for the locks in the queues. Fix this by doing the queue allocation after the setup() callback runs. This is safe because the setup() callback is not allowed to make any state changes that need to be undone on error (memory allocations, etc.). It may, however, make state changes that are undone by free_netdev() (such as netif_napi_add(), which is done by the ipoib driver's setup routine). The previous code also leaked a reference to the &init_net namespace object on RX/TX queue allocation failures. Signed-off-by: David S. Miller <davem@davemloft.net> 08 February 2011, 23:02:50 UTC
b2df5a8 David S. Miller 08 February 2011, 22:31:31 UTC net/caif: Fix dangling list pointer in freed object on error. rtnl_link_ops->setup(), and the "setup" callback passed to alloc_netdev*(), cannot make state changes which need to be undone on failure. There is no cleanup mechanism available at this point. So we have to add the caif private instance to the global list once we are sure that register_netdev() has succedded in ->newlink(). Otherwise, if register_netdev() fails, the caller will invoke free_netdev() and we will have a reference to freed up memory on the chnl_net_list. Signed-off-by: David S.

The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts.

Note: - this is an old SiS 965L motherboard - the 8168 chipset emits (lots of) control frames towards the sender - RTL_GIGA_MAC_VER_26 The chipset does not go into a frenzy of mac control pause when it crashes yet but it can still be crashed.

I found that one of the 8168c chipsets (concretely XID 1c4000c0) starts generating RxFIFO overflow errors.

9690c63 David S. Miller 04 February 2011, 00:12:50 UTC niu: Fix races between up/down and get_stats. As reported by Flavio Leitner, there is no synchronization to protect NIU's get_stats method from seeing a NULL pointer in either np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats is concerned, these values are set completely asynchronously. Flavio attempted to fix this using a RW semaphore, which in fact works most of the time. However, dev_get_stats() can be invoked from non-sleepable contexts in some cases, so this fix doesn't work in all cases. So instead, control the visibility of the np->{rx,tx}_ring pointers when the device is being brough up, and use properties of the device down sequence to our advantage. In niu_get_stats(), return immediately if netif_running() is false. The device shutdown sequence first marks the device as not running (by clearing the __LINK_STATE_START bit), then it performans a synchronize_rcu() (in dev_deactive_many()), and then finally it invokes the driver ->ndo_stop() method. This guarentees that all invocations of niu_get_stats() either see netif_running() as false, or they see the channel pointers before ->ndo_stop() clears them out. If netif_running() is true, protect against startup races by loading the np->{rx,tx}_rings pointer into a local variable, and punting if it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading the pointer on us. Also, during open, control the order in which the pointers and the ring counts become visible globally using SMP write memory barriers. We make sure the np->num_{rx,tx}_rings value is stable and visible before np->{rx,tx}_rings is. Such visibility control is not necessary on the niu_free_channels() side because of the RCU sequencing that happens during device down as described above. We are always guarenteed that all niu_get_stats calls are finished, or will see netif_running() false, by the time ->ndo_stop is invoked.

Fix this by keeping track of the hw_roc_skb pointer just for the status processing and use the correct cookie to report in this case. We can't use the hw_roc_skb pointer itself because it is NULL'ed when the frame is transmitted to prevent it being used twice.
