      dm thin: provide userspace access to pool metadata · cc8394d8
      Joe Thornber 提交于
      This patch implements two new messages that can be sent to the thin
      pool target allowing it to take a snapshot of the _metadata_.  This,
      read-only snapshot can be accessed by userland, concurrently with the
      live target.
      
      Only one metadata snapshot can be held at a time.  The pool's status
      line will give the block location for the current msnap.
      
      Since version 0.1.5 of the userland thin provisioning tools, the
      thin_dump program displays the msnap as follows:
      
          thin_dump -m <msnap root> <metadata dev>
      
      Available here: https://github.com/jthornber/thin-provisioning-tools
      
      Now that userland can access the metadata we can do various things
      that have traditionally been kernel side tasks:
      
           i) Incremental backups.
      
           By using metadata snapshots we can work out what blocks have
           changed over time.  Combined with data snapshots we can ensure
           the data doesn't change while we back it up.
      
           A short proof of concept script can be found here:
      
           https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb
      
           ii) Migration of thin devices from one pool to another.
      
           iii) Merging snapshots back into an external origin.
      
           iv) Asyncronous replication.

      dm mpath: allow ioctls to trigger pg init · 35991652
      Mikulas Patocka 提交于
      After the failure of a group of paths, any alternative paths that
      need initialising do not become available until further I/O is sent to
      the device.  Until this has happened, ioctls return -EAGAIN.
      
      With this patch, new paths are made available in response to an ioctl
      too.  The processing of the ioctl gets delayed until this has happened.
      
      Instead of returning an error, we submit a work item to kmultipathd
      (that will potentially activate the new path) and retry in ten
      milliseconds.
      
      Note that the patch doesn't retry an ioctl if the ioctl itself fails due
      to a path failure.  Such retries should be handled intelligently by the
      code that generated the ioctl in the first place, noting that some SCSI
      commands should not be retried because they are not idempotent (XOR write
      commands).  For commands that could be retried, there is a danger that
      if the device rejected the SCSI command, the path could be errorneously
      marked as failed, and the request would be retried on another path which
      might fail too.  It can be determined if the failure happens on the
      device or on the SCSI controller, but there is no guarantee that all
      SCSI drivers set these flags correctly.

      dm mpath: delay retry of bypassed pg · f220fd4e
      Mike Christie 提交于
      If I/O needs retrying and only bypassed priority groups are available,
      set the pg_init_delay_retry flag to wait before retrying.
      
      If, for example, the reason for the bypass is that the controller is
      getting reset or there is a firmware upgrade happening, retrying right
      away would cause a flood of log messages and retries for what could be a
      few seconds or even several minutes.

          b) Mirroring the device queue mapping of the SYN for the SYN/ACK

       4) When netlabel is disabled, we abort all IP option processing when we
          see a CIPSO option.  This isn't the right thing to do, we should
          simply skip over it and continue processing the remaining options

      tty: Revert the tty locking series, it needs more work · f309532b
      Linus Torvalds 提交于
      This reverts the tty layer change to use per-tty locking, because it's
      not correct yet, and fixing it will require some more deep surgery.
      
      The main revert is d29f3ef3 ("tty_lock: Localise the lock"), but
      there are several smaller commits that built upon it, they also get
      reverted here. The list of reverted commits is:
      
        fde86d31 - tty: add lockdep annotations
        8f6576ad - tty: fix ldisc lock inversion trace
        d3ca8b64 - pty: Fix lock inversion

        fd11b42e - cris: fix missing tty arg in wait_event_interruptible_tty call
        d29f3ef3 - tty_lock: Localise the lock
      
      The revert had a trivial conflict in the 68360serial.c staging driver
      that got removed in the meantime.

      The __kernel_nlink_t for powerpc got scrogged because 64-bit powerpc

      The config options in the Kconfig file (with _CODEPAGE_ in the name)

      And both of them were of the hard-to-read MACXYZZY variety, which made
      them hard to parse for normal humans: MACROMAN easily reads as "macro
      man", not as "Mac Roman".
      
      So rename the options to be consistent, and be NLS_MAC_xyzzy.  Rename

      x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32 · bad1a753
      H.J. Lu 提交于
      When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
      support for x32 GDB  For ARCH_GET_FS/GS, it takes a pointer to int64.  But
      at user level, ARCH_GET_FS/GS takes a pointer to int32.  So I have to add
      x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
      copy it back to GDB as int32.  Roland suggested that PTRACE_ARCH_PRCTL
      is obsolete and x32 GDB should use fs_base and gs_base fields of
      user_regs_struct instead.
      
      Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
      avoid possible memory overrun when pointer to int32 is passed to
      kernel.

      mtd: block2mtd: fix recursive call of mtd_writev · 2e24e32e
      Gabor Juhos 提交于
      The 'mtd_writev' interface calls the function assigned
      to the '_write' field of a given mtd device if that is
      not NULL. The block2mtd driver sets the '_writev' field
      to the 'mtd_writev' function itself and thus causes a
      endless loop.
      
      This is caused by 1dbebd32
      (mtd: harmonize mtd_writev usage).

      tcp: reflect SYN queue_mapping into SYNACK packets · fff32699
      Eric Dumazet 提交于
      While testing how linux behaves on SYNFLOOD attack on multiqueue device
      (ixgbe), I found that SYNACK messages were dropped at Qdisc level
      because we send them all on a single queue.
      
      Obvious choice is to reflect incoming SYN packet @queue_mapping to
      SYNACK packet.
      
      Under stress, my machine could only send 25.000 SYNACK per second (for
      200.000 incoming SYN per second). NIC : ixgbe with 16 rx/tx queues.
      
      After patch, not a single SYNACK is dropped.
