      xfrm_user: fix info leak in copy_to_user_auth() · 4c87308b
      Mathias Krause authored
      copy_to_user_auth() fails to initialize the remainder of alg_name and
      therefore discloses up to 54 bytes of heap memory via netlink to
      userland.
      
      Use strncpy() instead of strcpy() to fill the trailing bytes of alg_name
      with null bytes.

      net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 · 9db273f4
      Bjørn Mork authored
      One of the modes of Huawei E367 has this QMI/wwan interface:
      
       I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
       E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
       E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
       E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms
      
      Huawei use subclass and protocol to identify vendor specific
      functions, so adding a new vendor rule for this combination.
      
      The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
      the same subclass to identify the QMI/wwan function.  Replace the
      existing device specific UML290 entries with generic vendor matching,
      adding support for the Pantech P4200.
      
      The ZTE MF683 has 6 vendor specific interfaces, all using
      ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
      is a QMI/wwan interface.

      tcp: restore rcv_wscale in a repair mode (v2) · bc26ccd8
      Andrey Vagin authored
      rcv_wscale is a symetric parameter with snd_wscale.
      
      Both this parameters are set on a connection handshake.
      
      Without this value a remote window size can not be interpreted correctly,
      because a value from a packet should be shifted on rcv_wscale.
      
      And one more thing is that wscale_ok should be set too.
      
      This patch doesn't break a backward compatibility.
      If someone uses it in a old scheme, a rcv window
      will be restored with the same bug (rcv_wscale = 0).
      
      v2: Save backward compatibility on big-endian system. Before
          the first two bytes were snd_wscale and the second two bytes were
          rcv_wscale. Now snd_wscale is opt_val & 0xFFFF and rcv_wscale >> 16.
          This approach is independent on byte ordering.

      ====================
      This is a batch of fixes intended for the 3.6 stream.
      
      Arend van Spriel sends a simple thinko fix to correct a constant,
      preventing the setting of an invalid power level.
      
      Colin Ian King gives us a simple allocation failure check to avoid a
      NULL pointer dereference.
      
      Felix Fietkau sends another ath9k tx power patch, this time disabling a
      feature that has been reported to cause rx problems.
      
      Hante Meuleman provides a pair of endian fixes for brcmfmac.
      
      Larry Finger offers an rtlwifi fix that avoids a system lockup related
      to loading the wrong firmware for RTL8188CE devices.
      
      These have been in linux-next for a few days and I think they should be
      included in the final 3.6 kernel if possible.

      Pull GFS2 fixes from Steven Whitehouse:
       "Here are three GFS2 fixes for the current kernel tree.  These are all
        related to the block reservation code which was added at the merge
        window.  That code will be getting an update at the forthcoming merge
        window too.  In the mean time though there are a few smaller issues
        which should be fixed.
      
        The first patch resolves an issue with write sizes of greater than 32
        bits with the size hinting code.  The second ensures that the
        allocation data structure is initialised when using xattrs and the
        third takes into account allocations which may have been made by other
        nodes which affect a reservation on the local node."

       - Fixes a regression, introduced in 3.6-rc1, when a file is closed
         before its shared memory mapping is dirtied and unmapped.  The lower
         file was being released when the eCryptfs file was closed and the
         dirtied pages could not be written out.
       - Adds a call to the lower filesystem's ->flush() from
         ecryptfs_flush().
       - Fixes a regression, introduced in 2.6.39, when a file is renamed on
         top of another file.  The target file's inode was not being evicted
         and the space taken by the file was not reclaimed until eCryptfs was
         unmounted.

      vfs: make O_PATH file descriptors usable for 'fstat()' · 55815f70
      Linus Torvalds authored
      We already use them for openat() and friends, but fstat() also wants to
      be able to use O_PATH file descriptors.  This should make it more
      directly comparable to the O_SEARCH of Solaris.
      
      Note that you could already do the same thing with "fstatat()" and an
      empty path, but just doing "fstat()" directly is simpler and faster, so
      there is no reason not to just allow it directly.
      
      See also commit 332a2e12, which did the same thing for fchdir, for
      the same reasons.

      eCryptfs: Copy up attributes of the lower target inode after rename · 8335eafc
      Tyler Hicks authored
      After calling into the lower filesystem to do a rename, the lower target
      inode's attributes were not copied up to the eCryptfs target inode. This
      resulted in the eCryptfs target inode staying around, rather than being
      evicted, because i_nlink was not updated for the eCryptfs inode. This
      also meant that eCryptfs didn't do the final iput() on the lower target
      inode so it stayed around, as well. This would result in a failure to
      free up space occupied by the target file in the rename() operation.
      Both target inodes would eventually be evicted when the eCryptfs
      filesystem was unmounted.
      
      This patch calls fsstack_copy_attr_all() after the lower filesystem
      does its ->rename() so that important inode attributes, such as i_nlink,
      are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called
      and eCryptfs can drop its final reference on the lower inode.
