        operations to enhance its consistency along with checkpoint, 4) fixed
        subtle IO hang conditions and roll-forward recovery flow to resurrect

        Enhancements:
         - add checksum to keep superblock contents more safe

        fixes was a good idea. Darrick will take the helm again at the end of

        pending rework of the clone/dedupe_file_range code that fixes numerous
        bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
        reviewed and tested, Al and I just need to work out the details of the
        merge, so it may come from him rather than me.

         - only support filesystems with unwritten extents
      
         - add definition for statfs XFS magic number

      Pull btrfs updates from David Sterba:
       "This is the first batch with fixes and some nice performance
        improvements.
      
        Preliminary results show eg. more files/sec in fsmark, better perf on
        multi-threaded workloads (filebench, dbench), fewer context switches
        and overall better memory allocation characteristics (multiple
        benchmarks).
      
        Apart from general performance, there's an improvement for qgroups +
        balance workload that's been troubling our users.
      
        Note for stable: there are 20+ patches tagged for stable, out of 90.
        Not all of them apply cleanly on all stable versions but the conflicts
        are mostly due to simple cleanups and resolving should be obvious. The
        fixes are otherwise independent.
      
        Performance improvements:
      
         - transition between blocking and spinning modes of path is gone,
           which originally resulted to more unnecessary wakeups and updates
           to the path locks, the effects are measurable and improve latency
           and scalability
      
         - qgroups: first batch of changes that should speedup balancing with
           qgroups on, skip quota accounting on unchanged subtrees, overall
           gain is about 30+% in runtime
      
         - use rb-tree with cached first node for several structures, small
           improvement to avoid pointer chasing
      
        Fixes:
      
         - trim
            - fix: some blockgroups could have been missed if their logical
              address was past the total filesystem size (ie. after a lot of
              balancing)
            - better error reporting, after processing blockgroups and whole
              device
            - fix: continue trimming block groups after an error is
              encountered
            - check for trim support of the device earlier and avoid some
              unnecessary work
            - less interaction with transaction commit that improves latency
              on slower storage (eg. image files over NFS)
      
         - fsync
            - fix warning when replaying log after fsync of a O_TMPFILE
            - fix wrong dentries after fsync of file that got its parent
              replaced
      
         - qgroups: fix rescan that might misc some dirty groups
      
         - don't clean dirty pages during buffered writes, this could lead to
           lost updates in some corner cases
      
         - some block groups could have been delayed in creation, if the
           allocation triggered another one
      
         - error handling improvements
      
        Cleanups:
      
         - removed unused struct members and variables
      
         - function return type cleanups
      
         - delayed refs code refactoring

      Pull siginfo updates from Eric Biederman:
       "I have been slowly sorting out siginfo and this is the culmination of
        that work.
      
        The primary result is in several ways the signal infrastructure has
        been made less error prone. The code has been updated so that manually
        specifying SEND_SIG_FORCED is never necessary. The conversion to the
        new siginfo sending functions is now complete, which makes it
        difficult to send a signal without filling in the proper siginfo
        fields.
      
        At the tail end of the patchset comes the optimization of decreasing
        the size of struct siginfo in the kernel from 128 bytes to about 48
        bytes on 64bit. The fundamental observation that enables this is by
        definition none of the known ways to use struct siginfo uses the extra
        bytes.
      
        This comes at the cost of a small user space observable difference.
        For the rare case of siginfo being injected into the kernel only what
        can be copied into kernel_siginfo is delivered to the destination, the
        rest of the bytes are set to 0. For cases where the signal and the
        si_code are known this is safe, because we know those bytes are not
        used. For cases where the signal and si_code combination is unknown
        the bits that won't fit into struct kernel_siginfo are tested to
        verify they are zero, and the send fails if they are not.
      
        I made an extensive search through userspace code and I could not find
        anything that would break because of the above change. If it turns out
        I did break something it will take just the revert of a single change
        to restore kernel_siginfo to the same size as userspace siginfo.
      
        Testing did reveal dependencies on preferring the signo passed to
        sigqueueinfo over si->signo, so bit the bullet and added the
        complexity necessary to handle that case.
      
        Testing also revealed bad things can happen if a negative signal
        number is passed into the system calls. Something no sane application
        will do but something a malicious program or a fuzzer might do. So I
        have fixed the code that performs the bounds checks to ensure negative
        signal numbers are handled"

      net/kconfig: Make QCOM_QMI_HELPERS available when COMPILE_TEST · a978a5b8
      Linus Torvalds 提交于
      The networking merge brought in the experimental support for the
      Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
      dependency.
      
      But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
      ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
      the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
      doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.
      
      As a result, a "make allmodconfig" complains
      
        WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS
          Depends on [n]: ARCH_QCOM && NET [=y]

      tcp: add tcp_reset_xmit_timer() helper · 3f80e08f
      Eric Dumazet 提交于
      With EDT model, SRTT no longer is inflated by pacing delays.
      
      This means that RTO and some other xmit timers might be setup
      incorrectly. This is particularly visible with either :
      
      - Very small enforced pacing rates (SO_MAX_PACING_RATE)
      - Reduced rto (from the default 200 ms)
      
      This can lead to TCP flows aborts in the worst case,
      or spurious retransmits in other cases.
      
      For example, this session gets far more throughput
      than the requested 80kbit :
      
      $ netperf -H 127.0.0.2 -l 100 -- -q 10000
      MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET
      Recv   Send    Send

      540000 262144 262144    104.00      2.66
      
      With the fix :
      
      $ netperf -H 127.0.0.2 -l 100 -- -q 10000
      MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET
      Recv   Send    Send
      Socket Socket  Message  Elapsed

      540000 262144 262144    104.00      0.12
      
      EDT allows for better control of rtx timers, since TCP has
      a better idea of the earliest departure time of each skb
      in the rtx queue. We only have to eventually add to the
      timer the difference of the EDT time with current time.

      Ivan Vecera 提交于
      The mentioned commit needs to be reverted because we cannot pass
      string allocated on stack to request_irq(). This function stores
      uses this pointer for later use (e.g. /proc/interrupts) so we need
      to keep this string persistently.

      Revert "net: simplify sock_poll_wait" · 89ab066d
      Karsten Graul 提交于
      This reverts commit dd979b4d.
      
      This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an
      internal TCP socket for the initial handshake with the remote peer.
      Whenever the SMC connection can not be established this TCP socket is
      used as a fallback. All socket operations on the SMC socket are then
      forwarded to the TCP socket. In case of poll, the file->private_data
      pointer references the SMC socket because the TCP socket has no file
      assigned. This causes tcp_poll to wait on the wrong socket.

      net: socionext: Reset tx queue in ndo_stop · 8d5b0bf6
      Masahisa Kojima 提交于
      We observed that packets and bytes count are not reset
      when user performs interface down. Eventually, tx queue is
      exhausted and packets will not be sent out.
      To avoid this problem, resets tx queue in ndo_stop.

      net: socionext: Add dummy PHY register read in phy_write() · a3241a91
      Masahisa Kojima 提交于
      There is a compatibility issue between RTL8211E implemented
      in Developerbox and netsec ethernet controller IP.
      
      Our MDIO controller stops MDC clock right after the write
      access, but RTL8211E expects MDC clock must be kept toggling
      for several clock cycle with MDIO high before entering
      the IDLE state. Without keeping clock after write access,
      write access is not correctly handled and register is not
      updated.
      
      To meet this requirement, netsec driver needs to issue dummy
      read(e.g. read PHYID1(offset 0x2) register) right after write
      access, to keep MDC clock.
      
      We think this compatibility issue is a problem specific to
      our MDIO controller and RTL8211E.

      net: socionext: Stop PHY before resetting netsec · 8e850f25
      Masahisa Kojima 提交于
      In ndo_stop, driver resets the netsec ethernet controller IP.
      When the netsec IP is reset, HW running mode turns to NRM mode
      and driver has to wait until this mode transition completes.
      
      But mode transition to NRM will not complete if the PHY is
      in normal operation state. Netsec IP requires PHY is in
      power down state when it is reset.
      
      This modification stops the PHY before resetting netsec.
      
      Together with this modification, phy_addr is stored in netsec_priv
      structure because ndev->phydev is not yet ready in ndo_init.
