      Revert "Input: synaptics - enable RMI mode for X1 Extreme 2nd Generation" · 87916634
      Lyude Paul authored
      This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.
      
      Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
      works perfectly fine on the X1 Extreme Gen 2 except for one thing I
      didn't notice because I usually use the trackpoint: clicking with the
      touchpad. Somehow this is broken, in fact we don't even seem to indicate
      BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
      see any RMI4 events coming from the touchpad when I press down on it.
      This only seems to work for PS/2 mode.
      
      Since that means we have a regression, and PS/2 mode seems to work fine
      for the time being - revert this for now. We'll have to do a more
      thorough investigation on this.

      afs: Fix large file support · b485275f
      Marc Dionne authored
      By default s_maxbytes is set to MAX_NON_LFS, which limits the usable
      file size to 2GB, enforced by the vfs.
      
      Commit b9b1f8d5 ("AFS: write support fixes") added support for the
      64-bit fetch and store server operations, but did not change this value.
      As a result, attempts to write past the 2G mark result in EFBIG errors:
      
       $ dd if=/dev/zero of=foo bs=1M count=1 seek=2048
       dd: error writing 'foo': File too large
      
      Set s_maxbytes to MAX_LFS_FILESIZE.

      afs: Fix possible assert with callbacks from yfs servers · cd340703
      Marc Dionne authored
      Servers sending callback breaks to the YFS_CM_SERVICE service may
      send up to YFSCBMAX (1024) fids in a single RPC.  Anything over
      AFSCBMAX (50) will cause the assert in afs_break_callbacks to trigger.
      
      Remove the assert, as the count has already been checked against
      the appropriate max values in afs_deliver_cb_callback and
      afs_deliver_yfs_cb_callback.

      r8152: avoid to call napi_disable twice · 5b1d9c17
      Hayes Wang authored
      Call napi_disable() twice would cause dead lock. There are three situations
      may result in the issue.
      
      1. rtl8152_pre_reset() and set_carrier() are run at the same time.
      2. Call rtl8152_set_tunable() after rtl8152_close().
      3. Call rtl8152_set_ringparam() after rtl8152_close().
      
      For #1, use the same solution as commit 84811412 ("r8152: Re-order
      napi_disable in rtl8152_close"). For #2 and #3, add checking the flag
      of IFF_UP and using napi_disable/napi_enable during mutex.

      udp: drop skb extensions before marking skb stateless · 677bf08c
      Florian Westphal authored
      Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free
      assumes all skb head state has been dropped already.
      
      This will leak the extension memory in case the skb has extensions other
      than the ipsec secpath, e.g. bridge nf data.
      
      To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have
      extensions or if the extension space can be free'd.
      
      Fixes: 895b5c9f ("netfilter: drop bridge nf reset from nf_reset")

      net: rtnetlink: prevent underflows in do_setvfinfo() · ff08ddba
      Dan Carpenter authored
      The "ivm->vf" variable is a u32, but the problem is that a number of
      drivers cast it to an int and then forget to check for negatives.  An
      example of this is in the cxgb4 driver.

      mm/memory_hotplug: don't access uninitialized memmaps in shrink_zone_span() · 7ce700bf
      David Hildenbrand authored
      Let's limit shrinking to !ZONE_DEVICE so we can fix the current code.
      We should never try to touch the memmap of offline sections where we
      could have uninitialized memmaps and could trigger BUGs when calling
      page_to_nid() on poisoned pages.
      
      There is no reliable way to distinguish an uninitialized memmap from an
      initialized memmap that belongs to ZONE_DEVICE, as we don't have
      anything like SECTION_IS_ONLINE we can use similar to
      pfn_to_online_section() for !ZONE_DEVICE memory.
      
      E.g., set_zone_contiguous() similarly relies on pfn_to_online_section()
      and will therefore never set a ZONE_DEVICE zone consecutive.  Stopping
      to shrink the ZONE_DEVICE therefore results in no observable changes,
      besides /proc/zoneinfo indicating different boundaries - something we
      can totally live with.
      
      Before commit d0dc12e8 ("mm/memory_hotplug: optimize memory
      hotplug"), the memmap was initialized with 0 and the node with the right
      value.  So the zone might be wrong but not garbage.  After that commit,
      both the zone and the node will be garbage when touching uninitialized
      memmaps.
      
      Toshiki reported a BUG (race between delayed initialization of
      ZONE_DEVICE memmaps without holding the memory hotplug lock and
      concurrent zone shrinking).

        While creating a namespace and initializing memmap, if you destroy the
        namespace and shrink the zone, it will initialize the memmap outside
        the zone and trigger VM_BUG_ON_PAGE(!zone_spans_pfn(page_zone(page),
        pfn), page) in set_pfnblock_flags_mask()."
      
      This BUG is also mitigated by this commit, where we for now stop to
      shrink the ZONE_DEVICE zone until we can do it in a safe and clean way.

      hv_netvsc: Fix send_table offset in case of a host bug · 171c1fd9
      Haiyang Zhang authored
      If negotiated NVSP version <= NVSP_PROTOCOL_VERSION_6, the offset may
      be wrong (too small) due to a host bug. This can cause missing the
      end of the send indirection table, and add multiple zero entries from
      leading zeros before the data region. This bug adds extra burden on
      channel 0.
      
      So fix the offset by computing it from the data structure sizes. This
      will ensure netvsc driver runs normally on unfixed hosts, and future
      fixed hosts.

      hv_netvsc: Fix offset usage in netvsc_send_table() · 71f21959
      Haiyang Zhang authored
      To reach the data region, the existing code adds offset in struct
      nvsp_5_send_indirect_table on the beginning of this struct. But the
      offset should be based on the beginning of its container,
      struct nvsp_message. This bug causes the first table entry missing,
      and adds an extra zero from the zero pad after the data region.
      This can put extra burden on the channel 0.
      
      So, correct the offset usage. Also add a boundary check to ensure
      not reading beyond data region.
