2016-09-28drm/udl: fix line iterator in damage handlingDavid Herrmann
The udl damage handler is supposed to render 'height' lines, but its iterator has an obvious typo that makes it miss most lines if the rectangle does not cover 0/0. Fix the damage handler to correctly render all lines.

Miller <davem@davemloft.net>
2016-09-27act_ife: Fix false encodingYotam Gigi
On ife encode side, the action stores the different tlvs inside the ife header, where each tlv length field should refer to the length of the whole tlv (without additional padding) and not just the data length. On ife decode side, the action iterates over the tlvs in the ife header and parses them one by one, where in each iteration the current pointer is advanced according to the tlv size. Before, the encoding encoded only the data length inside the tlv, which led to false parsing of ife the header. In addition, due to the fact that the loop counter was unsigned, it could lead to infinite parsing loop. This fix changes the loop counter to be signed and fixes the encoding to take into account the tlv type and size.

2016-09-27act_ife: Fix external mac header on encodeYotam Gigi
On ife encode side, external mac header is copied from the original packet and may be overridden if the user requests. Before, the mac header copy was done from memory region that might not be accessible anymore, as skb_cow_head might free it and copy the packet. This led to random values in the external mac header once the values were not set by user. This fix takes the internal mac header from the packet, after the call to skb_cow_head.

2016-09-27Revert "net: ethernet: bcmgenet: use phydev from struct net_device"Florian Fainelli
This reverts commit 62469c76007e ("net: ethernet: bcmgenet: use phydev from struct net_device") because it causes GENETv1/2/3 adapters to expose the following behavior after an ifconfig down/up sequence: PING fainelli-linux (10.112.156.244): 56 data bytes 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.352 ms 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.472 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.496 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.517 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.536 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.557 ms (DUP!) 64 bytes from 10.112.156.244: seq=1 ttl=61 time=752.448 ms (DUP!) This was previously fixed by commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") but the commit we are reverting was essentially making this previous commit void, here is why. Without commit 62469c76007e we would have the following scenario after an ifconfig down then up sequence: - bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is initialized *before* we get to initialize the UniMAC, this is critical to ensure the PHY is in a correct state, priv->phydev is valid, this code executes fine - second time from bcmgenet_mii_probe(), through the normal phy_init_hw() call (which arguably could be optimized out) Everything is fine in that case. With commit 62469c76007e, we would have the following scenario to happen after an ifconfig down then up sequence: - bcmgenet_close() calls phy_disonnect() which makes dev->phydev become NULL - when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from bcmgenet_power_up() to initialize the internal PHY, the NULL check becomes true, so we do not reset the PHY, yet we keep going on and initialize the UniMAC, causing MAC activity to occur - we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is too late, the PHY is botched, and causes the above bogus pings/packets transmission/reception to occur Reported-by: Jaedon Shin <jaedon.shin@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

Eric Nelson says: ==================== net: fec: updates to align IP header This patch series is the outcome of investigation into very high numbers of alignment faults on kernel 4.1.33 from the linux-fslc tree: https://github.com/freescale/linux-fslc/tree/4.1-1.0.x-imx The first two patches remove support for the receive accelerator (RACC) from the i.MX25 and i.MX27 SoCs which don't support the function. The third patch enables hardware alignment of the ethernet packet payload (and especially the IP header) to prevent alignment faults in the IP stack. Testing on i.MX6UL on the 4.1.33 kernel showed that this patch removed on the order of 70k alignment faults during a 100MiB transfer using wget. Testing on an i.MX6Q (SABRE Lite) board on net-next (4.8.0-rc7) showed a much more modest improvement from 10's of faults, and it's not clear why that's the case. ==================== Acked-by: Fugang Duan <fugang.duan@nxp.com> Signed-off-by: David S.

The FEC receive accelerator (RACC) supports shifting the data payload of received packets by 16-bits, which aligns the payload (IP header) on a 4-byte boundary, which is, if not required, at least strongly suggested by the Linux networking layer.

2016-09-27serial: stm32: use mapbase instead of membase for DMAArnd Bergmann
Building this driver with a 64-bit dma_addr_t type results in a compiler warning: drivers/tty/serial/stm32-usart.c: In function 'stm32_of_dma_rx_probe': drivers/tty/serial/stm32-usart.c:746:20: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] drivers/tty/serial/stm32-usart.c: In function 'stm32_of_dma_tx_probe': drivers/tty/serial/stm32-usart.c:818:20: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] While the type conversion here is harmless, this hints at a different problem: we pass an __iomem pointer into a DMA engine, which expects a phys_addr_t. This happens to work because stm32 has no MMU and ioremap() is an identity mapping here, but it's still an incorrect API use. Using dma_addr_t is doubly wrong here, because that would be the result of dma_map_single() rather than the physical address. Using the mapbase instead fixes multiple issues: - the warning is gone - we don't go through ioremap in error - the cast is gone, making it use the correct resource_size_t/phys_addr_t type in the process.

2016-09-27usb: hub: change CLEAR_FEATURE to SET_FEATUREYonglong Wu
In USB20 specification, describes in chapter 9.4.5: The Remote Wakeup field can be modified by the SetFeature() and ClearFeature() requests using the DEVICE_REMOTE_WAKEUP feature selector. In USB30 specification, also describes in chapter 9.4.5: The Function Remote Wakeup field can be modified by the SetFeature() requests using the FUNCTION_SUSPEND feature selector. In chapter 9.4.9 Set Feature reference, it describes Function Remote Wake Enabled/Disabled at suspend options by SET_FEATURE. In USB30 specification only mentioned SetFeature(), so we need use SET_FEATURE replace CLEAR_FEATURE to disable USB30 function remote wakeup in suspend options.
