2018-10-08mmc: tegra: Reconfigure pad voltages during voltage switchingAapo Vienamo
Parse the pinctrl state and nvidia,only-1-8-v properties from the device tree. Validate the pinctrl and regulator configuration before unmasking UHS modes. Implement pad voltage state reconfiguration in the mmc start_signal_voltage_switch() callback. Add NVQUIRK_NEEDS_PAD_CONTROL and add set it for Tegra210 and Tegra186. The pad configuration is done in the mmc callback because the order of pad reconfiguration and sdhci voltage switch depend on the voltage to which the transition occurs.

2018-10-08mmc: sdhci-of-esdhc: add erratum A008171 supportYinbo Zhu
In tuning mode of operation, when TBCTL[TB_EN] is set, eSDHC may report one of the following errors : 1)Tuning error while running tuning operation where SYSCTL2[SAMPCLKSEL] will not get set even when SYSCTL2[EXTN] is reset. OR 2)Data transaction error (e.g. IRQSTAT[DCE], IRQSTAT[DEBE]) during data transaction errors. This issue occurs when the data window sampled within eSDHC is in full cycle. So, in that case, eSDHC is not able to find out the start and end points of the data window and sets the sampling pointer at default location (which is middle of the internal SD clock). If this sampling point coincides with the data eye boundary, then it can result in the above mentioned errors. Impact: Tuning mode of operation for SDR50, SDR104 or HS200 speed modes may not work properly Workaround: In case eSDHC reports tuning error or data errors in tuning mode of operation, by add the erratum A008171 support to fix the issue.

2018-10-08mmc: uniphier-sd: add UniPhier SD/eMMC controller driverMasahiro Yamada
Here is another TMIO MMC variant found in Socionext UniPhier SoCs. As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and MFD glue") said, these MMC controllers use the IP from Panasonic. However, the MMC controller in the TMIO (Toshiba Mobile IO) MFD chip was the first upstreamed user of this IP. The common driver code for this IP is now called 'tmio-mmc-core' in Linux although it is a historical misnomer. Anyway, this driver select's MMC_TMIO_CORE to borrow the common code from tmio-mmc-core.c Older UniPhier SoCs (LD4, Pro4, sLD8) support the external DMA engine like renesas_sdhi_sys_dmac.c. The difference is UniPhier SoCs use a single DMA channel whereas Renesas chips request separate channels for RX and TX. Newer UniPhier SoCs (Pro5 and later) support the internal DMA engine like renesas_sdhi_internal_dmac.c The register map is almost the same, so I guess Renesas and Socionext use the same internal DMA hardware. The main difference is, the register offsets are doubled for Renesas. Renesas Socionext SDHI UniPhier DM_CM_DTRAN_MODE 0x820 0x410 DM_CM_DTRAN_CTRL 0x828 0x414 DM_CM_RST 0x830 0x418 DM_CM_INFO1 0x840 0x420 DM_CM_INFO1_MASK 0x848 0x424 DM_CM_INFO2 0x850 0x428 DM_CM_INFO2_MASK 0x858 0x42c DM_DTRAN_ADDR 0x880 0x440 DM_DTRAN_ADDREX --- 0x444 This comes from the difference of host->bus_shift; 2 for Renesas SoCs, and 1 for UniPhier SoCs. Also, the datasheet for UniPhier SoCs defines DM_DTRAN_ADDR and DM_DTRAN_ADDREX as two separate registers. It could be possible to factor out the DMA common code by introducing some hooks to cope with platform quirks, but this patch does not touch that for now.

2018-10-08mmc: tmio: move tmio_mmc_set_clock() to platform hookMasahiro Yamada
tmio_mmc_set_clock() is full of quirks because different SoC vendors extended this in different ways. The original IP defines the divisor range 1/2 ... 1/512. bit 7 is set: 1/512 bit 6 is set: 1/256 ... bit 0 is set: 1/4 all bits clear: 1/2 It is platform-dependent how to achieve the 1/1 clock. I guess the TMIO-MFD variant uses the clock selector outside of this IP, as far as I see tmio_core_mmc_clk_div() in drivers/mfd/tmio_core.c I guess bit[7:0]=0xff is Renesas-specific extension. Socionext (and Panasonic) uses bit 10 (CLKSEL) for 1/1. Also, newer versions of UniPhier SoC variants use bit 16 for 1/1024. host->clk_update() is only used by the Renesas variants, whereas host->set_clk_div() is only used by the TMIO-MFD variants. To cope with this mess, promote tmio_mmc_set_clock() to a new platform hook ->set_clock(), and melt the old two hooks into it.

2018-10-05net: mvpp2: Extract the correct ethtype from the skb for tx csum offloadMaxime Chevallier
When offloading the L3 and L4 csum computation on TX, we need to extract the l3_proto from the ethtype, independently of the presence of a vlan tag. The actual driver uses skb->protocol as-is, resulting in packets with the wrong L4 checksum being sent when there's a vlan tag in the packet header and checksum offloading is enabled. This commit makes use of vlan_protocol_get() to get the correct ethtype regardless the presence of a vlan tag.

2018-10-05yam: fix a missing-check bugWenwen Wang
In yam_ioctl(), the concrete ioctl command is firstly copied from the user-space buffer 'ifr->ifr_data' to 'ioctl_cmd' and checked through the following switch statement. If the command is not as expected, an error code EINVAL is returned. In the following execution the buffer 'ifr->ifr_data' is copied again in the cases of the switch statement to specific data structures according to what kind of ioctl command is requested. However, after the second copy, no re-check is enforced on the newly-copied command. Given that the buffer 'ifr->ifr_data' is in the user space, a malicious user can race to change the command between the two copies. This way, the attacker can inject inconsistent data and cause undefined behavior. This patch adds a re-check in each case of the switch statement if there is a second copy in that case, to re-check whether the command obtained in the second copy is the same as the one in the first copy. If not, an error code EINVAL will be returned. Signed-off-by: Wenwen Wang <wang6495@umn.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

In cxgb_extension_ioctl(), the command of the ioctl is firstly copied from the user-space buffer 'useraddr' to 'cmd' and checked through the switch statement. If the command is not as expected, an error code EOPNOTSUPP is returned. In the following execution, i.e., the cases of the switch statement, the whole buffer of 'useraddr' is copied again to a specific data structure, according to what kind of command is requested. However, after the second copy, there is no re-check on the newly-copied command. Given that the buffer 'useraddr' is in the user space, a malicious user can race to change the command between the two copies. By doing so, the attacker can supply malicious data to the kernel and cause undefined behavior. This patch adds a re-check in each case of the switch statement if there is a second copy in that case, to re-check whether the command obtained in the second copy is the same as the one in the first copy.

2018-10-05i2c: designware: Call i2c_dw_clk_rate() only when calculating timingsJarkko Nikula
There are platforms which don't provide input clock rate but provide I2C timing parameters. Commit 3bd4f277274b ("i2c: designware: Call i2c_dw_clk_rate() only once in i2c_dw_init_master()") causes needless warning during probe on those platforms since i2c_dw_clk_rate(), which causes the warning when input clock is unknown, is called even when there is no need to calculate timing parameters.

2018-10-05iommu/amd: Clear memory encryption mask from physical addressSingh, Brijesh
Boris Ostrovsky reported a memory leak with device passthrough when SME is active. The VFIO driver uses iommu_iova_to_phys() to get the physical address for an iova. This physical address is later passed into vfio_unmap_unpin() to unpin the memory. The vfio_unmap_unpin() uses pfn_valid() before unpinning the memory. The pfn_valid() check was failing because encryption mask was part of the physical address returned. This resulted in the memory not being unpinned and therefore leaked after the guest terminates. The memory encryption mask must be cleared from the physical address in iommu_iova_to_phys().

2018-10-05net: phy: phylink: fix SFP interface autodetectionBaruch Siach
When connecting SFP PHY to phylink use the detected interface. Otherwise, the link fails to come up when the configured 'phy-mode' differs from the SFP detected mode. Move most of phylink_connect_phy() into __phylink_connect_phy(), and leave phylink_connect_phy() as a wrapper. phylink_sfp_connect_phy() can now pass the SFP detected PHY interface to __phylink_connect_phy(). This fixes 1GB SFP module link up on eth3 of the Macchiatobin board that is configured in the DT to "2500base-x" phy-mode.
