      libata: fix a couple of doc build warnings · 2f60e1ab
      Jonathan Corbet authored
      The kerneldoc comments for a couple of functions in drivers/ata/libata-eh.c
      had fallen behind the current implementation, resulting in these doc build
      warnings:
      
        ./drivers/ata/libata-eh.c:1449: warning: No description found for parameter 'link'
        ./drivers/ata/libata-eh.c:1449: warning: Excess function parameter 'ap' description in 'ata_eh_done'
        ./drivers/ata/libata-eh.c:1590: warning: No description found for parameter 'qc'
        ./drivers/ata/libata-eh.c:1590: warning: Excess function parameter 'dev' description in 'ata_eh_request_sense'
      
      Update the comments and make the warnings go away.

      libata: array underflow in ata_find_dev() · 59a5e266
      Dan Carpenter authored
      My static checker complains that "devno" can be negative, meaning that
      we read before the start of the loop.  I've looked at the code, and I
      think the warning is right.  This come from /proc so it's root only or
      it would be quite a quite a serious bug.  The call tree looks like this:
      
      proc_scsi_write() <- gets id and channel from simple_strtoul()
      -> scsi_add_single_device() <- calls shost->transportt->user_scan()
         -> ata_scsi_user_scan()
            -> ata_find_dev()

      libata: Cleanup ata_read_log_page() · 7cfdfdc8
      Damien Le Moal authored
      The warning message "READ LOG DMA EXT failed, trying unqueued" in
      ata_read_log_page() as well as the macro name ATA_HORKAGE_NO_NCQ_LOG
      are confusing: the command READ LOG DMA EXT is not an queued NCQ command
      unless it is encapsulated in a RECEIVE FPDMA QUEUED command.
      From ACS-4 READ LOG DMA EXT description:
      
      "The device processes the READ LOG DMA EXT command in the NCQ feature
      set environment (see 4.13.6) if the READ LOG DMA EXT command is
      encapsulated in a RECEIVE FPDMA QUEUED command (see 7.30) with the
      inputs encapsulated as shown in 7.23.6."
      
      To avoid confusion, fix the warning messsage to mention switching to PIO and
      not "unqueued" and rename the macro ATA_HORKAGE_NO_NCQ_LOG to
      ATA_HORKAGE_NO_DMA_LOG.

      afs: Add metadata xattrs · d3e3b7ea
      David Howells authored
      Add xattrs to allow the user to get/set metadata in lieu of having pioctl()
      available.  The following xattrs are now available:
      
       - "afs.cell"
      
         The name of the cell in which the vnode's volume resides.
      
       - "afs.fid"
      
         The volume ID, vnode ID and vnode uniquifier of the file as three hex
         numbers separated by colons.
      
       - "afs.volume"
      
         The name of the volume in which the vnode resides.
      
      For example:
      
      	# getfattr -d -m ".*" /mnt/scratch
      	getfattr: Removing leading '/' from absolute path names
      	# file: mnt/scratch
      	afs.cell="mycell.myorg.org"

      afs: Ignore AFS_ACE_READ and AFS_ACE_WRITE for directories · fd249821
      Marc Dionne authored
      The AFS_ACE_READ and AFS_ACE_WRITE permission bits should not
      be used to make access decisions for the directory itself.  They
      are meant to control access for the objects contained in that
      directory.
      
      Reading a directory is allowed if the AFS_ACE_LOOKUP bit is set.
      This would cause an incorrect access denied error for a directory
      with AFS_ACE_LOOKUP but not AFS_ACE_READ.
      
      The AFS_ACE_WRITE bit does not allow operations that modify the
      directory.  For a directory with AFS_ACE_WRITE but neither
      AFS_ACE_INSERT nor AFS_ACE_DELETE, this would result in trying
      operations that would ultimately be denied by the server.

      mqueue: fix a use-after-free in sys_mq_notify() · f991af3d
      Cong Wang authored
      The retry logic for netlink_attachskb() inside sys_mq_notify()
      is nasty and vulnerable:
      
      1) The sock refcnt is already released when retry is needed
      2) The fd is controllable by user-space because we already
         release the file refcnt
      
      so we when retry but the fd has been just closed by user-space
      during this small window, we end up calling netlink_detachskb()
      on the error path which releases the sock again, later when
      the user-space closes this socket a use-after-free could be
      triggered.
      
      Setting 'sock' to NULL here should be sufficient to fix it.

      Pull ext4 updates from Ted Ts'o:
       "The first major feature for ext4 this merge window is the largedir
        feature, which allows ext4 directories to support over 2 billion
        directory entries (assuming ~64 byte file names; in practice, users
        will run into practical performance limits first.) This feature was
        originally written by the Lustre team, and credit goes to Artem
        Blagodarenko from Seagate for getting this feature upstream.
      
        The second major major feature allows ext4 to support extended
        attribute values up to 64k. This feature was also originally from
        Lustre, and has been enhanced by Tahsin Erdogan from Google with a
        deduplication feature so that if multiple files have the same xattr
        value (for example, Windows ACL's stored by Samba), only one copy will
        be stored on disk for encoding and caching efficiency.
      
        We also have the usual set of bug fixes, cleanups, and optimizations"

      Remove useless local variables _match_, _soc_ and the code related.
      
      Notice that

      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.

      rds-tcp: sock_graft() leak
      
      Following up on the discussion at
        https://www.spinics.net/lists/netdev/msg442859.html
      - make rds_tcp_accept_one() call sock_create_lite()
      - add a WARN_ON() to sock_graft()
      
      Tested by running an infinite while() loop that does
      (module-load; rds-stress; module-unload) and monitors
      TCP slabinfo while the test is running.

      net/sock: add WARN_ON(parent->sk) in sock_graft() · 0ffdaf5b
      Sowmini Varadhan authored
      sock_graft() unilaterally sets up parent->sk based on the
      assumption that the existing parent->sk is null. If this
      condition is not true, then the existing parent->sk would
      be leaked, so add a WARN_ON() to alert callers who may fall
      in this category.

      rds: tcp: use sock_create_lite() to create the accept socket · 0933a578
      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().
