      net: make skb_gso_segment error handling more robust · 330966e5
      Florian Westphal authored
      skb_gso_segment has three possible return values:
      1. a pointer to the first segmented skb
      2. an errno value (IS_ERR())
      3. NULL.  This can happen when GSO is used for header verification.
      However, several callers currently test IS_ERR instead of IS_ERR_OR_NULL
      and would oops when NULL is returned.
      Note that these call sites should never actually see such a NULL return
      value; all callers mask out the GSO bits in the feature argument.
      However, there have been issues with some protocol handlers erronously not
      respecting the specified feature mask in some cases.
      It is preferable to get 'have to turn off hw offloading, else slow' reports
      rather than 'kernel crashes'.

      net: gso: use feature flag argument in all protocol gso handlers · 1e16aa3d
      Florian Westphal authored
      skb_gso_segment() has a 'features' argument representing offload features
      available to the output path.
      A few handlers, e.g. GRE, instead re-fetch the features of skb->dev and use
      those instead of the provided ones when handing encapsulation/tunnels.
      Depending on dev->hw_enc_features of the output device skb_gso_segment() can
      then return NULL even when the caller has disabled all GSO feature bits,
      as segmentation of inner header thinks device will take care of segmentation.
      This e.g. affects the tbf scheduler, which will silently drop GRE-encap GSO skbs
      that did not fit the remaining token quota as the segmentation does not work
      when device supports corresponding hw offload capabilities.

      netfilter fixes for net
      The following patchset contains netfilter fixes for your net tree,
      they are:
      1) Fix missing MODULE_LICENSE() in the new nf_reject_ipv{4,6} modules.
      2) Restrict nat and masq expressions to the nat chain type. Otherwise,
         users may crash their kernel if they attach a nat/masq rule to a non
         nat chain.
      3) Fix hook validation in nft_compat when non-base chains are used.
         Basically, initialize hook_mask to zero.
      4) Make sure you use match/targets in nft_compat from the right chain
         type. The existing validation relies on the table name which can be
         avoided by
      5) Better netlink attribute validation in nft_nat. This expression has
         to reject the configuration when no address and proto configurations
         are specified.
      6) Interpret NFTA_NAT_REG_*_MAX if only if NFTA_NAT_REG_*_MIN is set.

      ax88179_178a: fix bonding failure · 95ff8868
      Ian Morgan authored
      The following patch fixes a bug which causes the ax88179_178a driver to be
      incapable of being added to a bond.
      When I brought up the issue with the bonding maintainers, they indicated
      that the real problem was with the NIC driver which must return zero for
      success (of setting the MAC address). I see that several other NIC drivers
      follow that pattern by either simply always returing zero, or by passing
      through a negative (error) result while rewriting any positive return code
      to zero. With that same philisophy applied to the ax88179_178a driver, it
      allows it to work correctly with the bonding driver.
      I believe this is suitable for queuing in -stable, as it's a small, simple,
      and obvious fix that corrects a defect with no other known workaround.
      This patch is against vanilla 3.17(.0).

      sparc64: Do not define thread fpregs save area as zero-length array. · e2653143
      David S. Miller authored
      This breaks the stack end corruption detection facility.
      What that facility does it write a magic value to "end_of_stack()"
      and checking to see if it gets overwritten.
      "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
      the beginning of the FPU register save area.
      So once the user uses the FPU, the magic value is overwritten and the
      debug checks trigger.
      Fix this by making the size explicit.
      Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
      are limited to 7 levels of FPU state saves.  So each FPU register set
      is 256 bytes, allocate 256 * 7 for the fpregs area.

      sparc64: Fix corrupted thread fault code. · 84bd6d8b
      David S. Miller authored
      Every path that ends up at do_sparc64_fault() must install a valid
      FAULT_CODE_* bitmask in the per-thread fault code byte.
      Two paths leading to the label winfix_trampoline (which expects the
      FAULT_CODE_* mask in register %g4) were not doing so:
      1) For pre-hypervisor TLB protection violation traps, if we took
         the 'winfix_trampoline' path we wouldn't have %g4 initialized
         with the FAULT_CODE_* value yet.  Resulting in using the
         TLB_TAG_ACCESS register address value instead.
      2) In the TSB miss path, when we notice that we are going to use a
         hugepage mapping, but we haven't allocated the hugepage TSB yet, we
         still have to take the window fixup case into consideration and
         in that particular path we leave %g4 not setup properly.
      Errors on this sort were largely invisible previously, but after
      commit 4ccb9272 ("sparc64: sun4v TLB
      error power off events") we now have a fault_code mask bit
      (FAULT_CODE_BAD_RA) that triggers due to this bug.
      FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
      (see #1 above) and thus we get seemingly random bus errors triggered
      for user processes.

           ->queue_rq() hook for blk-mq instead, freeing up one of the request
           bits.  The space was overly tight on 32-bit, so Martin also killed
           REQ_KERNEL since it's no longer used.

           have a per hardware context flush request, which both cleans up the
           code should scale better for flush intensive workloads on blk-mq.

           without preallocating a lot of memory.

           hardware queues from me.
         - Limit memory consumption for blk-mq devices for crash dump

      Pull md updates from Neil Brown:
       - a few minor bug fixes
       - quite a lot of code tidy-up and simplification
       - remove PRINT_RAID_DEBUG ioctl.  I'm fairly sure it is unused, and it
         isn't particularly useful.

        lib/raid6: Add log level to printks

        md: discard PRINT_RAID_DEBUG ioctl
        md: remove MD_BUG()
        md: clean up 'exit' labels in md_ioctl().
        md: remove unnecessary test for MD_MAJOR in md_ioctl()
        md: don't allow "-sync" to be set for device in an active array.
        md: remove unwanted white space from md.c
        md: don't start resync thread directly from md thread.
        md: Just use RCU when checking for overlap between arrays.
        md: avoid potential long delay under pers_lock
        md: simplify export_array()
        md: discard find_rdev_nr in favour of find_rdev_nr_rcu
        md: use wait_event() to simplify md_super_wait()
        md: be more relaxed about stopping an array which isn't started.
        md/raid1: process_checks doesn't use its return value.
        md/raid5: fix init_stripe() inconsistencies
        md/raid10: another memory leak due to reshape.
        md: use set_bit/clear_bit instead of shift/mask for bi_flags changes.
        md/raid1: minor typos and reformatting.

      x86,kvm,vmx: Preserve CR4 across VM entry · d974baa3
      Andy Lutomirski authored
      CR4 isn't constant; at least the TSD and PCE bits can vary.
      TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
      like it's correct.
      This adds a branch and a read from cr4 to each vm entry.  Because it is
      extremely likely that consecutive entries into the same vcpu will have
      the same host cr4 value, this fixes up the vmcs instead of restoring cr4
      after the fact.  A subsequent patch will add a kernel-wide cr4 shadow,
      reducing the overhead in the common case to just two memory reads and a

      pskb_may_pull() may change skb->data and make greh pointer oboslete;
