      ====================
      bnxt_en: Bug fixes.
      
      3 bug fixes in this series.  Fix a crash in bnxt_get_stats64() that can
      happen if the device is closing and freeing the statistics block at the
      same time.  The 2nd one fixes ethtool -L failing when changing from
      combined to non-combined mode or vice versa.  The last one fixes SRIOV
      failure on big-endian systems because we were setting a bitmap wrong in
      a firmware message.

      bnxt_en: Fix SRIOV on big-endian architecture. · 9b0436c3
      Michael Chan authored
      The PF driver sets up a list of firmware commands from the VF driver that
      needs to be forwarded to the PF for approval.  This list is a 256-bit
      bitmap.  The code that sets up the bitmap falls apart on big-endian
      architecture.  __set_bit() does not work because it operates on long types
      whereas the firmware interface is defined in u32 types, causing bits in
      the wrong 32-bit word to be set.
      
      Fix it by setting the proper bits on an array of u32.
      
      Fixes: de68f5de ("bnxt_en: Fix bitmap declaration to work on 32-bit arches.")

      bnxt_en: Fix bug in ethtool -L. · 3b6b34df
      Michael Chan authored
      When changing channels from combined to rx/tx or vice versa, the code
      uses the wrong "sh" parameter to determine if we are reserving rings
      for shared or non-shared mode.  It should be using the ethtool requested
      "sh" parameter instead of the current "sh" parameter.
      
      Fix it by passing the "sh" parameter to bnxt_reserve_rings().  For
      ethtool, we will pass in the requested "sh" parameter.
      
      Fixes: 391be5c2 ("bnxt_en: Implement new scheme to reserve tx rings.")

      bnxt_en: Fix race conditions in .ndo_get_stats64(). · f9b76ebd
      Michael Chan authored
      .ndo_get_stats64() may not be protected by RTNL and can race with
      .ndo_stop() or other ethtool operations that can free the statistics
      memory.  Fix it by setting a new flag BNXT_STATE_READ_STATS and then
      proceeding to read statistics memory only if the state is OPEN.  The
      close path that frees the memory clears the OPEN state and then waits
      for the BNXT_STATE_READ_STATS to clear before proceeding to free the
      statistics memory.

      bonding: avoid NETDEV_CHANGEMTU event when unregistering slave · f51048c3
      WANG Cong authored
      As Hongjun/Nicolas summarized in their original patch:
      
      "
      When a device changes from one netns to another, it's first unregistered,
      then the netns reference is updated and the dev is registered in the new
      netns. Thus, when a slave moves to another netns, it is first
      unregistered. This triggers a NETDEV_UNREGISTER event which is caught by
      the bonding driver. The driver calls bond_release(), which calls
      dev_set_mtu() and thus triggers NETDEV_CHANGEMTU (the device is still in
      the old netns).
      "
      
      This is a very special case, because the device is being unregistered
      no one should still care about the NETDEV_CHANGEMTU event triggered
      at this point, we can avoid broadcasting this event on this path,
      and avoid touching inetdev_event()/addrconf_notify() path.
      
      It requires to export __dev_set_mtu() to bonding driver.

      Sowmini Varadhan authored
      There are two problems with calling sock_create_kern() from
      rds_tcp_accept_one()
      1. it sets up a new_sock->sk that is wasteful, because this ->sk
         is going to get replaced by inet_accept() in the subsequent ->accept()
      2. The new_sock->sk is a leaked reference in sock_graft() which
         expects to find a null parent->sk
      
      Avoid these problems by calling sock_create_lite().

      Pull iov_iter hardening from Al Viro:
       "This is the iov_iter/uaccess/hardening pile.
      
        For one thing, it trims the inline part of copy_to_user/copy_from_user
        to the minimum that *does* need to be inlined - object size checks,
        basically. For another, it sanitizes the checks for iov_iter
        primitives. There are 4 groups of checks: access_ok(), might_fault(),
        object size and KASAN.
      
         - access_ok() had been verified by whoever had set the iov_iter up.
           However, that has happened in a function far away, so proving that
           there's no path to actual copying bypassing those checks is hard
           and proving that iov_iter has not been buggered in the meanwhile is
           also not pleasant. So we want those redone in actual
           copyin/copyout.
      
         - might_fault() is better off consolidated - we know whether it needs
           to be checked as soon as we enter iov_iter primitive and observe
           the iov_iter flavour. No need to wait until the copyin/copyout. The
           call chains are short enough to make sure we won't miss anything -
           in fact, it's more robust that way, since there are cases where we
           do e.g. forced fault-in before getting to copyin/copyout. It's not
           quite what we need to check (in particular, combination of
           iovec-backed and set_fs(KERNEL_DS) is almost certainly a bug, not a
           cause to skip checks), but that's for later series. For now let's
           keep might_fault().
      
         - KASAN checks belong in copyin/copyout - at the same level where
           other iov_iter flavours would've hit them in memcpy().
      
         - object size checks should apply to *all* iov_iter flavours, not
           just iovec-backed ones.
      
        There are two groups of primitives - one gets the kernel object
        described as pointer + size (copy_to_iter(), etc.) while another gets
        it as page + offset + size (copy_page_to_iter(), etc.)
      
        For the first group the checks are best done where we actually have a
        chance to find the object size. In other words, those belong in inline
        wrappers in uio.h, before calling into iov_iter.c. Same kind as we
        have for inlined part of copy_to_user().
      
        For the second group there is no object to look at - offset in page is
        just a number, it bears no type information. So we do them in the
        common helper called by iov_iter.c primitives of that kind. All it
        currently does is checking that we are not trying to access outside of
        the compound page; eventually we might want to add some sanity checks
        on the page involved.
      
        So the things we need in copyin/copyout part of iov_iter.c do not
        quite match anything in uaccess.h (we want no zeroing, we *do* want
        access_ok() and KASAN and we want no might_fault() or object size
        checks done on that level). OTOH, these needs are simple enough to
        provide a couple of helpers (static in iov_iter.c) doing just what we
        need..."

      Pull Writeback error handling updates from Jeff Layton:
       "This pile represents the bulk of the writeback error handling fixes
        that I have for this cycle. Some of the earlier patches in this pile
        may look trivial but they are prerequisites for later patches in the
        series.
      
        The aim of this set is to improve how we track and report writeback
        errors to userland. Most applications that care about data integrity
        will periodically call fsync/fdatasync/msync to ensure that their
        writes have made it to the backing store.
      
        For a very long time, we have tracked writeback errors using two flags
        in the address_space: AS_EIO and AS_ENOSPC. Those flags are set when a
        writeback error occurs (via mapping_set_error) and are cleared as a
        side-effect of filemap_check_errors (as you noted yesterday). This
        model really sucks for userland.
      
        Only the first task to call fsync (or msync or fdatasync) will see the
        error. Any subsequent task calling fsync on a file will get back 0
        (unless another writeback error occurs in the interim). If I have
        several tasks writing to a file and calling fsync to ensure that their
        writes got stored, then I need to have them coordinate with one
        another. That's difficult enough, but in a world of containerized
        setups that coordination may even not be possible.
      
        But wait...it gets worse!
      
        The calls to filemap_check_errors can be buried pretty far down in the
        call stack, and there are internal callers of filemap_write_and_wait
        and the like that also end up clearing those errors. Many of those
        callers ignore the error return from that function or return it to
        userland at nonsensical times (e.g. truncate() or stat()). If I get
        back -EIO on a truncate, there is no reason to think that it was
        because some previous writeback failed, and a subsequent fsync() will
        (incorrectly) return 0.
      
        This pile aims to do three things:
      
         1) ensure that when a writeback error occurs that that error will be
            reported to userland on a subsequent fsync/fdatasync/msync call,
            regardless of what internal callers are doing
      
         2) report writeback errors on all file descriptions that were open at
            the time that the error occurred. This is a user-visible change,
            but I think most applications are written to assume this behavior
            anyway. Those that aren't are unlikely to be hurt by it.
      
         3) document what filesystems should do when there is a writeback
            error. Today, there is very little consistency between them, and a
            lot of cargo-cult copying. We need to make it very clear what
            filesystems should do in this situation.
      
        To achieve this, the set adds a new data type (errseq_t) and then
        builds new writeback error tracking infrastructure around that. Once
        all of that is in place, we change the filesystems to use the new
        infrastructure for reporting wb errors to userland.
      
        Note that this is just the initial foray into cleaning up this mess.
        There is a lot of work remaining here:
      
         1) convert the rest of the filesystems in a similar fashion. Once the
            initial set is in, then I think most other fs' will be fairly
            simple to convert. Hopefully most of those can in via individual
            filesystem trees.
      
         2) convert internal waiters on writeback to use errseq_t for
            detecting errors instead of relying on the AS_* flags. I have some
            draft patches for this for ext4, but they are not quite ready for
            prime time yet.
      
        This was a discussion topic this year at LSF/MM too. If you're
        interested in the gory details, LWN has some good articles about this:

       "The main rationale for all of these changes is to tighten up writeback
        error reporting to userland. There are many ways now that writeback

      dentry name snapshots · 49d31c2f
      Al Viro authored
      take_dentry_name_snapshot() takes a safe snapshot of dentry name;
      if the name is a short one, it gets copied into caller-supplied
      structure, otherwise an extra reference to external name is grabbed
      (those are never modified).  In either case the pointer to stable
      string is stored into the same structure.
      
      dentry must be held by the caller of take_dentry_name_snapshot(),
      but may be freely dropped afterwards - the snapshot will stay
      until destroyed by release_dentry_name_snapshot().
      
      Intended use:
      	struct name_snapshot s;
      
      	take_dentry_name_snapshot(&s, dentry);
      	...
      	access s.name
      	...
      	release_dentry_name_snapshot(&s);
      
      Replaces fsnotify_oldname_...(), gets used in fsnotify to obtain the name
      to pass down with event.

       "Thin archives migration by Nicholas Piggin.
      
        THIN_ARCHIVES has been available for a while as an optional feature
        only for PowerPC architecture, but we do not need two different
        intermediate-artifact schemes.
      
        Using thin archives instead of conventional incremental linking has
        various advantages:
      
         - save disk space for builds
      
         - speed-up building a little
      
         - fix some link issues (for example, allyesconfig on ARM) due to more
           flexibility for the final linking
      
         - work better with dead code elimination we are planning
      
        As discussed before, this migration has been done unconditionally so
        that any problems caused by this will show up with "git bisect".
