      xen-netfront: Update features after registering netdev · 45c8184c
      Ross Lagerwall authored
      Update the features after calling register_netdev() otherwise the
      device features are not set up correctly and it not possible to change
      the MTU of the device. After this change, the features reported by
      ethtool match the device's features before the commit which introduced
      the issue and it is possible to change the device's MTU.

      cls_flower: fix use after free in flower S/W path · 44a5cd43
      Paolo Abeni authored
      If flower filter is created without the skip_sw flag, fl_mask_put()
      can race with fl_classify() and we can destroy the mask rhashtable
      while a lookup operation is accessing it.

      net: macb: Fix ptp time adjustment for large negative delta · 64d7839a
      Harini Katakam authored
      When delta passed to gem_ptp_adjtime is negative, the sign is
      maintained in the ns_to_timespec64 conversion. Hence timespec_add
      should be used directly. timespec_sub will just subtract the negative
      value thus increasing the time difference.

      ipvlan: fix IFLA_MTU ignored on NEWLINK · 30877961
      Xin Long authored
      Commit 296d4856 ("ipvlan: inherit MTU from master device") adjusted
      the mtu from the master device when creating a ipvlan device, but it
      would also override the mtu value set in rtnl_create_link. It causes
      IFLA_MTU param not to take effect.
      
      So this patch is to not adjust the mtu if IFLA_MTU param is set when
      creating a ipvlan device.

      Currently it is incrementing SctpFragUsrMsgs when the user message size
      is of the exactly same size as the maximum fragment size, which is wrong.
      
      The fix is to increment it only when user message is bigger than the
      maximum fragment size.

      net: mscc: fix the injection header · 08d02364
      Antoine Tenart authored
      When injecting frames in the Ocelot switch driver an injection header
      (IFH) should be used to configure various parameters related to a given
      frame, such as the port onto which the frame should be departed or its
      vlan id. Other parameters in the switch configuration can led to an
      injected frame being sent without an IFH but this led to various issues
      as the per-frame parameters are then not used. This is especially true
      when using multiple ports for injection.
      
      The IFH was injected with the wrong endianness which led to the switch
      not taking it into account as the IFH_INJ_BYPASS bit was then unset.
      (The bit tells the switch to use the IFH over its internal
      configuration). This patch fixes it.
      
      In addition to the endianness fix, the IFH is also fixed. As it was
      (unwillingly) unused, some of its fields were not configured the right
      way.

      In function strp_data_ready(), it is useless to call queue_work if
      the state of strparser is already paused. The state checking should
      be done before calling queue_work. The change reduces the context

      HID: wacom: Correct logical maximum Y for 2nd-gen Intuos Pro large · d471b6b2
      Jason Gerecke authored
      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.

      HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation · ebeaa367
      Even Xu authored
      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.

      HID: steam: use hid_device.driver_data instead of hid_set_drvdata() · 4bff980f
      Rodrigo Rivas Costa authored
      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.

      proc: fix missing final NUL in get_mm_cmdline() rewrite · f5b65348
      Linus Torvalds authored
      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.

      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.

      net: sungem: fix rx checksum support · 12b03558
      Eric Dumazet authored
      After commit 88078d98 ("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.
