2012-06-12bonding: Fix corrupted queue_mappingEric Dumazet
In the transmit path of the bonding driver, skb->cb is used to stash the skb->queue_mapping so that the bonding device can set its own queue mapping. This value becomes corrupted since the skb->cb is also used in __dev_xmit_skb. When transmitting through bonding driver, bond_select_queue is called from dev_queue_xmit. In bond_select_queue the original skb->queue_mapping is copied into skb->cb (via bond_queue_mapping) and skb->queue_mapping is overwritten with the bond driver queue. Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes the packet length into skb->cb, thereby overwriting the stashed queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit), the queue mapping for the skb is set to the stashed value which is now the skb length and hence is an invalid queue for the slave device. If we want to save skb->queue_mapping into skb->cb[], best place is to add a field in struct qdisc_skb_cb, to make sure it wont conflict with other layers (eg : Qdiscc, Infiniband...) This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8 bytes : netem qdisc for example assumes it can store an u64 in it, without misalignment penalty. Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[]. The largest user is CHOKe and it fills it. Based on a previous patch from Tom Herbert.

2012-06-12drm/ttm: Fix buffer object metadata accounting regression v2Thomas Hellstrom
A regression was introduced in the 3.3 rc series, commit "drm/ttm: simplify memory accounting for ttm user v2", causing the metadata of buffer objects created using the ttm_bo_create() function to be accounted twice. That causes massive leaks with the vmwgfx driver running for example SpecViewperf Catia-03 test 2, eventually killing the app. Furthermore, the same commit introduces a regression where metadata accounting is leaked if a buffer object is initialized with an illegal size. This is also fixed with this commit. v2: Fixed an error path and removed an unused variable.

2012-06-12drm: increase DRM_OBJECT_MAX_PROPERTY to 24Paulo Zanoni
Before Kernel 3.5, no one was checking for the return value of drm_connector_attach_property, so we never noticed that we were unable to create some properties. Commit "drm: WARN() when drm_connector_attach_property fails" added a WARN when we fail to create a property, and the transition from "connector properties" to "object properties" changed the warning message a little bit. On i915 machines with many TV connectors we hit the maximum number of properties (since each TV connector uses a lot of properties), so we get a few backtraces in our logs. This commit increases the maximum number of properties to 24 hoping we'll have enough room for everybody. Chris suggested that we convert this code to "lists", but I believe this conversion can come after we make sure people's dmesgs are not spammed by our driver.

2012-06-12perf tools: Fix synthesizing tracepoint names from the perf.data headersArnaldo Carvalho de Melo
We need to use the per event info snapshoted at record time to synthesize the events name, so do it just after reading the perf.data headers, when we already processed the /sys events data, otherwise we'll end up using the local /sys that only by sheer luck will have the same tracepoint ID -> real event association.

2012-06-11staging: usbip: bugfix for stack corruption on 64-bit architecturesBart Westgeest
Previously a 6 byte array (buf) was erroneously cast to a 8 byte long (event_bits) on 64-bit architectures which caused a stack corruption. Signed-off-by: Bart Westgeest <bart@elbrys.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-06-11tilegx network driver: initial supportChris Metcalf
This change adds support for the tilegx network driver based on the GXIO IORPC support in the tilegx software stack, using the on-chip mPIPE packet processing engine. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-11staging/comedi: fix build for USB not enabledRandy Dunlap
Calls to optional subsystems cannot be made indiscriminately. Enclose all of the usb helper functions inside #if IS_ENABLED(CONFIG_USB) to fix these build errors. (The pci helper functions are OK since there are stubs in linux/pci.h for the called functions when PCI is not enabled. Possibly the same could be done for the called USB functions.)

2012-06-11net: stmmac: Fix clock en-/disable callsStefan Roese
clk_{un}prepare is mandatory for platforms using common clock framework. Since these drivers are used by SPEAr platform, which supports common clock framework, add clk_{un}prepare() support for them. Otherwise the clocks are not correctly en-/disabled and ethernet support doesn't work.

2012-06-11rpc_pipefs: allow rpc_purge_list to take a NULL waitq pointerJeff Layton
In the event that we don't have a dentry for a rpc_pipefs pipe, we still need to allow the queue_timeout job to clean out the queue. There's just no waitq to wake up in that event.

Commit 536e43d12b9517bbbf6114cd1a12be27857a4d7a ATTR_OPEN check can result in an ia_valid with only ATTR_FILE set, and no NFS_VALID_ATTRS attributes to request from the server. Signed-off-by: Andy Adamson <andros@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-06-11NFSv2: EOF incorrectly set on short readSachin Prabhu
In cases where the server returns fewer bytes then those requested, we can incorrectly set the eof flag for the file. Fixing this allows the request to be retried with updated offset and count arguments. Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-06-11lpc_eth: fix tx completionEric Dumazet
__lpc_handle_xmit() has two bugs : 1) It can leak skbs in case TXSTATUS_ERROR is set 2) It can wake up txqueue while no slot was freed.

2012-06-11lpc_eth: add missing ndo_change_mtu()Eric Dumazet
lpc_eth does a copy of transmitted skbs to DMA area, without checking skb lengths, so can trigger buffer overflows : memcpy(pldat->tx_buff_v + txidx * ENET_MAXF_SIZE, skb->data, len); One way to get bigger skbs is to allow MTU changes above the 1500 limit. Calling eth_change_mtu() in ndo_change_mtu() makes sure this cannot happen.
