2018-06-22xen: Remove unnecessary BUG_ON from __unbind_from_irq()Boris Ostrovsky1-2/+0
Commit 910f8befdf5b ("xen/pirq: fix error path cleanup when binding MSIs") fixed a couple of errors in error cleanup path of xen_bind_pirq_msi_to_irq(). This cleanup allowed a call to __unbind_from_irq() with an unbound irq, which would result in triggering the BUG_ON there. Since there is really no reason for the BUG_ON (xen_free_irq() can operate on unbound irqs) we can remove it.

2018-06-22xen: add new hypercall buffer mapping deviceJuergen Gross4-1/+223
For passing arbitrary data from user land to the Xen hypervisor the Xen tools today are using mlock()ed buffers. Unfortunately the kernel might change access rights of such buffers for brief periods of time e.g. for page migration or compaction, leading to access faults in the hypervisor, as the hypervisor can't use the locks of the kernel. In order to solve this problem add a new device node to the Xen privcmd driver to easily allocate hypercall buffers via mmap(). The memory is allocated in the kernel and just mapped into user space. Marked as VM_IO the user mapping will not be subject to page migration et al.

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.

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.

2018-06-20net: 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.

2018-06-20net: hamradio: use eth_broadcast_addrStefan Agner1-6/+2
The array bpq_eth_addr is only used to get the size of an address, whereas the bcast_addr is used to set the broadcast address. This leads to a warning when using clang: drivers/net/hamradio/bpqether.c:94:13: warning: variable 'bpq_eth_addr' is not needed and will not be emitted [-Wunneeded-internal-declaration] static char bpq_eth_addr[6]; ^ Remove both variables and use the common eth_broadcast_addr to set the broadcast address.

2018-06-20bpf, xdp, i40e: fix i40e_build_skb skb reserve and truesizeDaniel Borkmann1-4/+3
Using skb_reserve(skb, I40E_SKB_PAD + (xdp->data - xdp->data_hard_start)) is clearly wrong since I40E_SKB_PAD already points to the offset where the original xdp->data was sitting since xdp->data_hard_start is defined as xdp->data - i40e_rx_offset(rx_ring) where latter offsets to I40E_SKB_PAD when build skb is used. However, also before cc5b114dcf98 ("bpf, i40e: add meta data support") this seems broken since bpf_xdp_adjust_head() helper could have been used to alter headroom and enlarge / shrink the frame and with that the assumption that the xdp->data remains unchanged does not hold and would push a bogus packet to upper stack. ixgbe got this right in 924708081629 ("ixgbe: add XDP support for pass and drop actions"). In any case, fix it by removing the I40E_SKB_PAD from both skb_reserve() and truesize calculation.

2018-06-20qed: Fix possible memory leak in Rx error path handling.Sudarsana Reddy Kalluru1-2/+9
Memory for packet buffers need to be freed in the error paths as there is no consumer (e.g., upper layer) for such packets and that memory will never get freed. The issue was uncovered when port was attacked with flood of isatap packets, these are multicast packets hence were directed at all the PFs. For foce PF, this meant they were routed to the ll2 module which in turn drops such packets.
