2011-02-14netfilter: nf_iterate: fix incorrect RCU usagePatrick McHardy
As noticed by Eric, nf_iterate doesn't use RCU correctly by accessing the prev pointer of a RCU protected list element when a verdict of NF_REPEAT is issued. Fix by jumping backwards to the hook invocation directly instead of loading the previous list element before continuing the list iteration.

2011-02-13ATM, Solos PCI ADSL2+: Don't deref NULL pointer if net_ratelimit() and ↵Jesper Juhl
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().

2011-02-13Net, USB, Option, hso: Do not dereference NULL pointerJesper Juhl
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.

2011-02-12bridge: Replace mp->mglist hlist with a boolHerbert Xu
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.

2011-02-11bridge: Fix timer typo that may render snooping less effectiveHerbert Xu
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. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-02-11bridge: Fix mglist corruption that leads to memory corruptionHerbert Xu
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.

2011-02-08net: Fix lockdep regression caused by initializing netdev queues too early.David S. Miller
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>
2011-02-08net/caif: Fix dangling list pointer in freed object on error.David S. Miller
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. Miller <davem@davemloft.net>

2011-02-08ixgbe: fix for 82599 erratum on Header SplittingDon Skidmore
We have found a hardware erratum on 82599 hardware that can lead to unpredictable behavior when Header Splitting mode is enabled. So we are no longer enabling this feature on affected hardware. Please see the 82599 Specification Update for more information.

This patch adds support for Marvell Alask M88E188R PHY chips. Support for other M88* PHYs is already there, so there is nothing more to add than its PHY id.

2011-02-08e1000e: tx_timeout should not increment for non-hang eventsJesse Brandeburg
Currently the driver increments the tx_timeout counter (an error counter) when simply resetting the part with outstanding transmit work pending. This is an unnecessary count of an error, when all we should be doing is just resetting the part and discarding the transmits. With this change the only increment of tx_timeout is when the stack calls the watchdog reset function due to a true Tx timeout.

2011-02-08batman-adv: Linearize fragment packets before mergeSven Eckelmann
We access the data inside the skbs of two fragments directly using memmove during the merge. The data of the skb could span over multiple skb pages. An direct access without knowledge about the pages would lead to an invalid memory access.

2011-02-07x25: possible skb leak on bad facilitiesandrew hendry
Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308f94dc ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f9a429 ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts. So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

2011-02-07mac80211: fix the skb cloned check in the tx pathFelix Fietkau
Using skb_header_cloned to check if it's safe to write to the skb is not enough - mac80211 also touches the tailroom of the skb. Initially this check was only used to increase a counter, however this commit changed the code to also skip skb data reallocation if no extra head/tailroom was needed: commit 4cd06a344db752f513437138953af191cbe9a691 mac80211: skip unnecessary pskb_expand_head calls It added a regression at least with iwl3945, which is fixed by this patch.
