The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains a typo which defines an incorrect logical maximum Y value. This causes a small portion of the bottom of the tablet to become unusable (both because the area is below the "bottom" of the tablet and because 'wacom_wac_event' ignores out-of-range values). It also results in a skewed aspect ratio. To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites the data with the correct value.

2018-06-20HID: intel_ish-hid: ipc: register more pm callbacks to support hibernationEven Xu1-15/+7
Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

2018-06-20HID: steam: use hid_device.driver_data instead of hid_set_drvdata()Rodrigo Rivas Costa1-5/+5
When creating the low-level hidraw device, the reference to steam_device was stored using hid_set_drvdata(). But this value is not guaranteed to be kept when set before calling probe. If this pointer is reset, it crashes when opening the emulated hidraw device. It looks like hid_set_drvdata() is for users "avobe" this hid_device, while hid_device.driver_data it for users "below" this one. In this case, we are creating a virtual hidraw device, so we must use hid_device.driver_data.

2018-06-20proc: fix missing final NUL in get_mm_cmdline() rewriteLinus Torvalds1-5/+23
The rewrite of the cmdline fetching missed the fact that we used to also return the final terminating NUL character of the last argument. I hadn't noticed, and none of the tools I tested cared, but something obviously must care, because Michal Kubecek noticed the change in behavior. Tweak the "find the end" logic to actually include the NUL character, and once past the eend of argv, always start the strnlen() at the expected (original) argument end. This whole "allow people to rewrite their arguments in place" is a nasty hack and requires that odd slop handling at the end of the argv array, but it's our traditional model, so we continue to support it.

2018-06-20ip: limit use of gso_size to udpWillem de Bruijn2-2/+4
The ipcm(6)_cookie field gso_size is set only in the udp path. The ip layer copies this to cork only if sk_type is SOCK_DGRAM. This check proved too permissive. Ping and l2tp sockets have the same type. Limit to sockets of type SOCK_DGRAM and protocol IPPROTO_UDP to exclude ping sockets. v1 -> v2 - remove irrelevant whitespace changes Fixes: bec1f6f69736 ("udp: generate gso with UDP_SEGMENT") Reported-by: Maciej Żenczykowski <maze@google.com> Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

HW does not support Half-duplex mode in multi-queue scenario. Fix it by not advertising the Half-Duplex mode if multi-queue enabled. Signed-off-by: Bhadram Varka <vbhadram@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-06-20net: stmmac: socfpga: add additional ocp reset line for Stratix10Dinh Nguyen2-5/+15
The Stratix10 platform has an additional reset line, OCP(Open Core Protocol), that also needs to get deasserted for the stmmac ethernet controller to work. Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build dwmac-socfpga. Also, remove the redundant check for the reset controller pointer. The reset driver already checks for the pointer and returns 0 if the pointer is NULL. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-06-20net: sungem: fix rx checksum supportEric Dumazet1-10/+12
After commit 88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends"), sungem owners reported the infamous "eth0: hw csum failure" message. CHECKSUM_COMPLETE has in fact never worked for this driver, but this was masked by the fact that upper stacks had to strip the FCS, and therefore skb->ip_summed was set back to CHECKSUM_NONE before my recent change. Driver configures a number of bytes to skip when the chip computes the checksum, and for some reason only half of the Ethernet header was skipped. Then a second problem is that we should strip the FCS by default, unless the driver is updated to eventually support NETIF_F_RXFCS in the future. Finally, a driver should check if NETIF_F_RXCSUM feature is enabled or not, so that the admin can turn off rx checksum if wanted. Many thanks to Andreas Schwab and Mathieu Malaterre for their help in debugging this issue.
