2014-08-07cxgb4: IEEE fixes for DCBx state machineAnish Bhatt5-71/+216
* Changes required due to 16eecd9be4b05 ("dcbnl : Fix misleading dcb_app->priority explanation") * Driver was previously not aware of what DCBx version was negotiated by firmware, this could lead to DCB app table in kernel or in firmware being populated wrong since IEEE/CEE used different formats made clear by above mentioned commit * Driver was missing a couple of state transitions that could be caused by other drivers that use chelsio hardware, resulting in incorrect behaviour (the change that addresses this also flips the state machine to switch on state instead of transition, hope this is okay in current window) * Prio queue info & tsa is no longer thrown away v2: Print DCBx state transition messages only when debug is enabled Signed-off-by: Anish Bhatt <[email protected]> Signed-off-by: David S.

2014-08-07net: ucc_geth: make probe consistently acquire a reference to the phy nodeUwe Kleine-König1-1/+1
When the driver attaches to a device that has a phy handle the probe routine returns with a reference to that node. This reference is correctly dropped in the error path and the remove function. In the fixed phy case however no reference is acquired and so the error path might drop a reference the driver isn't holding. Fix that by getting a reference to the MAC.

Make sure that fs_enet_probe is left with a reference to the phy node. In the presence of a phy handle this is already the case as of_parse_phandle returns a reference. In the fixed phy case a call to of_node_get is necessary. Otherwise the error path and remove function drop a reference the driver isn't holding.

2014-08-07net: gianfar: fix reference counting for phy_nodeUwe Kleine-König1-2/+2
The line before the changed if condition is: priv->phy_node = of_parse_phandle(np, "phy-handle", 0); . If this call succeeds priv->phy_node must not be overwritten in the if block; otherwise the reference to the node returned by of_parse_phandle is lost. So add a check that the if block isn't executed in this case. Furthermore in the fixed phy case no reference is aquired for phy_node resulting in an of_node_put without holding a reference. To fix that, get a reference on the MAC dt node. Fixes: be40364544bd ("gianfar: use the new fixed PHY helpers") Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: David S.

2014-08-05amd-xgbe: Perform phy connect/disconnect at dev open/stopLendacky, Thomas2-99/+121
A change added to the mdiobus/phy api added a module_get/module_put during phy connect/disconnect processing. Currently, the driver performs a phy connect during module probe and a phy disconnect during module remove. With the addition of the module_get during phy connect the amd-xgbe module use count is incremented and can no longer be unloaded. Move the phy connect/disconnect from the driver probe/remove functions to the net_device_ops ndo_open/ndo_stop functions. This allows the module use count to be decremented when the device(s) are brought down and allows the module to be unloaded. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: David S.

Use the dma_set_mask_and_coherent function to set the DMA mask rather than setting the DMA mask fields directly. This was originally done to work around a bug in the arm64 DMA support when RAM started above the 4GB boundary which has since been fixed.

2014-08-05net: sun4i-emac: fix memory leak on bad packetMarc Zyngier1-2/+4
Upon reception of a new frame, the emac driver checks for a number of error conditions, and flag the packet as "bad" if any of these are present. It then allocates a skb unconditionally, but only uses it if the packet is "good". On the error path, the skb is just forgotten, and the system leaks memory. The piece of junk I have on my desk seems to encounter such error frequently enough so that the box goes OOM after a couple of days, which makes me grumpy. Fix this by moving the allocation on the "good_packet" path (and convert it to netdev_alloc_skb while we're at it). Tested on a random Allwinner A20 board.

The problem with the original commit is explained by Russell King: "It has the effect (as can be seen from the oops) of attaching the MDIO bus device (itself is a bus-less device) to the platform driver, which means that if the platform driver supports power management, it will be called to power manage the MDIO bus device. Moreover, drivers do not expect to be called for power management operations for devices which they haven't probed, and certainly not for devices which aren't part of the same bus that the driver is registered against."

2014-08-05xen-netback: Turn off the carrier if the guest is not able to receiveZoltan Kiss3-38/+123
Currently when the guest is not able to receive more packets, qdisc layer starts a timer, and when it goes off, qdisc is started again to deliver a packet again. This is a very slow way to drain the queues, consumes unnecessary resources and slows down other guests shutdown. This patch change the behaviour by turning the carrier off when that timer fires, so all the packets are freed up which were stucked waiting for that vif. Instead of the rx_queue_purge bool it uses the VIF_STATUS_RX_PURGE_EVENT bit to signal the thread that either the timeout happened or an RX interrupt arrived, so the thread can check what it should do. It also disables NAPI, so the guest can't transmit, but leaves the interrupts on, so it can resurrect. Only the queues which brought down the interface can enable it again, the bit QUEUE_STATUS_RX_STALLED makes sure of that.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next Conflicts: net/6lowpan/iphc.c Minor conflicts in iphc.c were changes overlapping with some style cleanups. John W. Linville says: ==================== Please pull this last(?) batch of wireless change intended for the 3.17 stream... For the NFC bits, Samuel says: "This is a rather quiet one, we have: - A new driver from ST Microelectronics for their NCI ST21NFCB, including device tree support. - p2p support for the ST21NFCA driver - A few fixes an enhancements for the NFC digital laye" For the Atheros bits, Kalle says: "Michal and Janusz did some important RX aggregation fixes, basically we were missing RX reordering altogether. The 10.1 firmware doesn't support Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc support with that firmware. Also he implemented a workaround for a KVM issue." For the Bluetooth bits, Gustavo and Johan say: "To quote Gustavo from his previous request: 'Some last minute fixes for -next. We have a fix for a use after free in RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with auto-connection handling. Last, we added support for reading the codec and MWS setting for controllers that support these features.' Additionally there are fixes to LE scanning, an update to conform to the 4.1 core specification as well as fixes for tracking the page scan state. All of these fixes are important for 3.17." And, "We've got: - 6lowpan fixes/cleanups - A couple crash fixes, one for the Marvell HCI driver and another in LE SMP. - Fix for an incorrect connected state check - Fix for the bondable requirement during pairing (an issue which had crept in because of using "pairable" when in fact the actual meaning was "bondable" (these have different meanings in Bluetooth)" Along with those are some late-breaking hardware support patches in brcmfmac and b43 as well as a stray ath9k patch. ==================== Signed-off-by: David S.
