      Richard Weinberger authored
      Currently it's possible to create a volume without a name. E.g:
      ubimkvol -n 32 -s 2MiB -t static /dev/ubi0 -N ""
      
      After that vtbl_check() will always fail because it does not permit
      empty strings.

      We have some problems related to selection of empty queues
      that need to be resolved, evidence so far points to the
      recursive merge logic making either being the cause or at
      least the accelerator for this. So revert it for now, until
      we figure this out.

      fsnotify: don't BUG in fsnotify_destroy_mark() · fed47485
      Miklos Szeredi authored
      Removing the parent of a watched file results in "kernel BUG at
      fs/notify/mark.c:139".
      
      To reproduce
      
        add "-w /tmp/audit/dir/watched_file" to audit.rules
        rm -rf /tmp/audit/dir
      
      This is caused by fsnotify_destroy_mark() being called without an
      extra reference taken by the caller.
      
      Reported by Francesco Cosoleto here:
      
        https://bugzilla.novell.com/show_bug.cgi?id=689860
      
      Fix by removing the BUG_ON and adding a comment about not accessing mark after
      the iput.

      dm: do not forward ioctls from logical volumes to the underlying device · ec8013be

      A logical volume can map to just part of underlying physical volume.
      In this case, it must be treated like a partition.

      block: fail SCSI passthrough ioctls on partition devices · 0bfc96cb
      Paolo Bonzini authored
      Linux allows executing the SG_IO ioctl on a partition or LVM volume, and
      will pass the command to the underlying block device.  This is
      well-known, but it is also a large security problem when (via Unix
      permissions, ACLs, SELinux or a combination thereof) a program or user
      needs to be granted access only to part of the disk.
      
      This patch lets partitions forward a small set of harmless ioctls;
      others are logged with printk so that we can see which ioctls are
      actually sent.  In my tests only CDROM_GET_CAPABILITY actually occurred.
      Of course it was being sent to a (partition on a) hard disk, so it would
      have failed with ENOTTY and the patch isn't changing anything in
      practice.  Still, I'm treating it specially to avoid spamming the logs.
      
      In principle, this restriction should include programs running with
      CAP_SYS_RAWIO.  If for example I let a program access /dev/sda2 and
      /dev/sdb, it still should not be able to read/write outside the
      boundaries of /dev/sda2 independent of the capabilities.  However, for
      now programs with CAP_SYS_RAWIO will still be allowed to send the
      ioctls.  Their actions will still be logged.
      
      This patch does not affect the non-libata IDE driver.  That driver
      however already tests for bd != bd->bd_contains before issuing some
      ioctl; it could be restricted further to forbid these ioctls even for
      programs running with CAP_SYS_ADMIN/CAP_SYS_RAWIO.

      Introduce a wrapper around scsi_cmd_ioctl that takes a block device.
      
      The function will then be enhanced to detect partition block devices

      GPIO: sa1100: implement proper gpiolib gpio_to_irq conversion · f408c985
      Russell King authored
      The existing gpio_to_irq() implementation on sa1100 only translates
      validly for internal GPIOs.  Since this sub-arch enables GPIOLIB
      support, this results in buggy translations for non-internal GPIOs.
      
      Get rid of the private gpio_to_irq() implementation, replacing it
      with the .to_irq method in the sa1100 gpio chip instead.

      Unused iocbs in a batch should not be accounted as active. · 69e4747e
      Gleb Natapov authored
      Since commit 080d676d ("aio: allocate kiocbs in batches") iocbs are
      allocated in a batch during processing of first iocbs.  All iocbs in a
      batch are automatically added to ctx->active_reqs list and accounted in
      ctx->reqs_active.
      
      If one (not the last one) of iocbs submitted by an user fails, further
      iocbs are not processed, but they are still present in ctx->active_reqs
      and accounted in ctx->reqs_active.  This causes process to stuck in a D
      state in wait_for_all_aios() on exit since ctx->reqs_active will never
      go down to zero.  Furthermore since kiocb_batch_free() frees iocb
      without removing it from active_reqs list the list become corrupted
      which may cause oops.
      
      Fix this by removing iocb from ctx->active_reqs and updating
      ctx->reqs_active in kiocb_batch_free().

      x86/mce: Fix CPU hotplug and suspend regression related to MCE · a3301b75
      Srivatsa S. Bhat authored
      Commit 8a25a2fd ("cpu: convert 'cpu' and 'machinecheck' sysdev_class
      to a regular subsystem") changed how things are dealt with in the MCE
      subsystem.  Some of the things that got broken due to this are CPU
      hotplug and suspend/hibernate.
      
      MCE uses per_cpu allocations of struct device.  So, when a CPU goes
      offline and comes back online, in order to ensure that we start from a
      clean slate with respect to the MCE subsystem, zero out the entire
      per_cpu device structure to 0 before using it.
