       "I recently took maintainership of the befs file system [0]. This is
        the first time I send you a git pull request, so please let me know if
        all the below is OK.
      
        Salah Triki and myself have been cleaning the code and fixing a few
        small bugs.
      
        Sorry I couldn't send this sooner in the merge window, I was waiting
        to have my GPG key signed by kernel members at ELCE in Berlin a few
        days ago."

      Pull gcc plugins update from Kees Cook:
       "This adds a new gcc plugin named "latent_entropy". It is designed to
        extract as much possible uncertainty from a running system at boot
        time as possible, hoping to capitalize on any possible variation in
        CPU operation (due to runtime data differences, hardware differences,
        SMP ordering, thermal timing variation, cache behavior, etc).
      
        At the very least, this plugin is a much more comprehensive example
        for how to manipulate kernel code using the gcc plugin internals"

      Pull cifs fixes from Steve French:
       "Including:
      
         - nine bug fixes for stable. Some of these we found at the recent two
           weeks of SMB3 test events/plugfests.
      
         - significant improvements in reconnection (e.g. if server or network
           crashes) especially when mounted with "persistenthandles" or to
           server which advertises Continuous Availability on the share.
      
         - a new mount option "idsfromsid" which improves POSIX compatibility
           in some cases (when winbind not configured e.g.) by better (and
           faster) fetching uid/gid from acl (when "cifsacl" mount option is
           enabled). NB: we are almost complete work on "cifsacl" (querying
           mode/uid/gid from ACL) for SMB3, but SMB3 support for cifsacl is
           not included in this set.
      
         - improved handling for SMB3 "credits" (even if server is buggy)
      
        Still working on two sets of changes:
      
         - cifsacl enablement for SMB3
      
         - cleanup of RFC1001 length calculation (so we can handle encryption
           and multichannel and RDMA)
      
        And a couple of new bugs were reported recently (unrelated to above)
        so will probably have another merge request next week"

      fs/super.c: don't fool lockdep in freeze_super() and thaw_super() paths · f1a96220
      Oleg Nesterov authored
      sb_wait_write()->percpu_rwsem_release() fools lockdep to avoid the
      false-positives. Now that xfs was fixed by Dave's commit dbad7c99
      
      
      ("xfs: stop holding ILOCK over filldir callbacks") we can remove it and
      change freeze_super() and thaw_super() to run with s_writers.rw_sem locks
      held; we add two trivial helpers for that, lockdep_sb_freeze_release()
      and lockdep_sb_freeze_acquire().
      
      xfstests-dev/check `grep -il freeze tests/*/???` does not trigger any
      warning from lockdep.

      fs/super.c: fix race between freeze_super() and thaw_super() · 89f39af1
      Oleg Nesterov authored
      
      
      Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than
      frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which
      drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering.
      
      In this case thaw_super() will wrongly call s_op->unfreeze_fs() before
      it was actually frozen, and call sb_freeze_unlock() which leads to the
      unbalanced percpu_up_write(). Unfortunately lockdep can't detect this,
      so this triggers misc BUG_ON()'s in kernel/rcu/sync.c.

      overlayfs: Fix setting IOP_XATTR flag · 655042cc
      Vivek Goyal authored
      
      
      ovl_fill_super calls ovl_new_inode to create a root inode for the new
      superblock before initializing sb->s_xattr.  This wrongly causes
      IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux
      to log the following message:
      
        SELinux: (dev overlay, type overlay) has no xattr support
      
      Fix this by initializing sb->s_xattr and similar fields before calling
      ovl_new_inode.

      iov_iter: kernel-doc import_iovec() and rw_copy_check_uvector() · ffecee4f
      Vegard Nossum authored
      
      
      Both import_iovec() and rw_copy_check_uvector() take an array
      (typically small and on-stack) which is used to hold an iovec array copy
      from userspace. This is to avoid an expensive memory allocation in the
      fast path (i.e. few iovec elements).
      
      The caller may have to check whether these functions actually used
      the provided buffer or allocated a new one -- but this differs between
      the too. Let's just add a kernel doc to clarify what the semantics are
      for each function.

      Pull rdma qedr RoCE driver from Doug Ledford:
       "Early on in the merge window I mentioned I had a backlog of new
        drivers waiting to be reviewed and that, in addition to the hns-roce
        driver, I wanted to get possible a couple more reviewed. I ended up
        only having the time to complete one of the additional drivers.
      
        During Dave Miller's pull request this go around, there were a series
        of 9 patches to the QLogic qed net driver that add basic support for a
        paired RoCE driver. That support is currently not functional because
        it is missing the matching RoCE driver in the RDMA subsystem. I
        managed to finish that review. However, because it goes against part
        of Dave's net pull, and a part that was accepted a day or two after
        the merge window opened, to apply cleanly it has to be applied to
        either the tip of Dave's net branch, or as I did in this case, I just
        applied it to your master after you had taken Dave's pull request."

       "This merge window was the first where Huawei had to try and coordinate
        their patches between their net driver and their new roce driver
        (similar to mlx4 and mlx5).
      
        They didn't do horribly, but there were some issues (and we knew that
        because they simply didn't know what to do in the beginning). As a
        result, I had a set of patches that depended on some patches that
        normally would have come to you via Dave's tree. Those patches have
        been on netdev@ for a while, so I got Dave to give me his approval to
        send them to you. As such, the other 29 patches I had behind them are
        also now ready to go.
      
        This catches the hns and hns-roce drivers up to current, and for
        future patches we are working with them to get them up to speed on how
        to do joint driver development so that they don't have these sorts of
        cross tree dependency issues again. BTW, Dave gave me permission to
        add his Acked-by: to the patches against the net tree, but I've had
        this branch through 0day (but not linux-next since it was off by
        itself) and I didn't want to rebase the series just to add Dave's ack
        for the 8 patches in the net area.
      
        Updates to the hns drivers:
      
         - Small patch set for hns net driver that the roce patches depend on
      
         - Various fixes to the hns-roce driver

           which currently is unsafe and may cause the processor to generate a

      CIFS: Retrieve uid and gid from special sid if enabled · 3514de3f
      Steve French authored
      
      
      New mount option "idsfromsid" indicates to cifs.ko that
      it should try to retrieve the uid and gid owner fields
      from special sids.  This patch adds the code to parse the owner
      sids in the ACL to see if they match, and if so populate the
      uid and/or gid from them.  This is faster than upcalling for
      them and asking winbind, and is a fairly common case, and is
      also helpful when cifs.upcall and idmapping is not configured.

      Add "idsfromsid" mount option to indicate to cifs.ko that it should
      try to retrieve the uid and gid owner fields from special sids in the
      ACL if present.  This first patch just adds the parsing for the mount
      option.
