      headers: utsname.h redux · 2bcd57ab
      Alexey Dobriyan authored
      * remove asm/atomic.h inclusion from linux/utsname.h --
         not needed after kref conversion
       * remove linux/utsname.h inclusion from files which do not need it
      
      NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
      due to some personality stuff it _is_ needed -- cowardly leave ELF-related
      headers and files alone.

      Revert "kmod: fix race in usermodehelper code" · 95e0d86b
      Sebastian Andrzej Siewior authored
      This reverts commit c02e3f36 ("kmod: fix race in usermodehelper code")
      
      The patch is wrong.  UMH_WAIT_EXEC is called with VFORK what ensures
      that the child finishes prior returing back to the parent.  No race.
      
      In fact, the patch makes it even worse because it does the thing it
      claims not do:
      
       - It calls ->complete() on UMH_WAIT_EXEC
      
       - the complete() callback may de-allocated subinfo as seen in the
         following call chain:
      
          [<c009f904>] (__link_path_walk+0x20/0xeb4) from [<c00a094c>] (path_walk+0x48/0x94)
          [<c00a094c>] (path_walk+0x48/0x94) from [<c00a0a34>] (do_path_lookup+0x24/0x4c)
          [<c00a0a34>] (do_path_lookup+0x24/0x4c) from [<c00a158c>] (do_filp_open+0xa4/0x83c)
          [<c00a158c>] (do_filp_open+0xa4/0x83c) from [<c009ba90>] (open_exec+0x24/0xe0)
          [<c009ba90>] (open_exec+0x24/0xe0) from [<c009bfa8>] (do_execve+0x7c/0x2e4)
          [<c009bfa8>] (do_execve+0x7c/0x2e4) from [<c0026a80>] (kernel_execve+0x34/0x80)
          [<c0026a80>] (kernel_execve+0x34/0x80) from [<c004b514>] (____call_usermodehelper+0x130/0x148)
          [<c004b514>] (____call_usermodehelper+0x130/0x148) from [<c0024858>] (kernel_thread_exit+0x0/0x8)
      
         and the path pointer was NULL.  Good that ARM's kernel_execve()
         doesn't check the pointer for NULL or else I wouldn't notice it.
      
      The only race there might be is with UMH_NO_WAIT but it is too late for
      me to investigate it now.  UMH_WAIT_PROC could probably also use VFORK
      and we could save one exec.  So the only race I see is with UMH_NO_WAIT
      and recent scheduler changes where the child does not always run first
      might have trigger here something but as I said, it is late....

      NFS: Propagate 'fsc' mount option through automounts · 2df54806
      David Howells authored
      Propagate the NFS 'fsc' mount option through NFS automounts of various types.
      
      This is now required as commit:
      
      	commit c02d7adf
      	Author: Trond Myklebust <Trond.Myklebust@netapp.com>

      	NFSv4: Replace nfs4_path_walk() with VFS path lookup in a private namespace
      
      uses VFS-driven automounting to reach all submounts barring the root, thus
      preventing fscaching from being enabled on any submount other than the root.
      
      This patch gets around that by propagating the NFS_OPTION_FSCACHE flag across
      automounts.  If a uniquifier is supplied to a mount then this is propagated to
      all automounts of that mount too.

      Allocating nfs_parsed_mount_data and setting up the defaults is nearly
      the same for both nfs and nfs4 mounts.
      
      Both paths seem to use nfs_validate_transport_protocol(), so setting a
      default value for nfs_server.protocol ought to be unnecessary.

      NFS/RPC: fix problems with reestablish_timeout and related code. · 61d0a8e6
      Neil Brown authored
      
      [[resending with correct cc:  - "vfs.kernel.org" just isn't right!]]
      
      xprt->reestablish_timeout is used to cause TCP connection attempts to
      back off if the connection fails so as not to hammer the network,
      but to still allow immediate connections when there is no reason to
      believe there is a problem.
      
      It is not used for the first connection (when transport->sock is NULL)
      but only on reconnects.
      
      It is currently set:
      
       a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1
          on the assumption that the client has closed the connection
          so the reconnect should be immediate when needed.
       b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change
          detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the
          server closed the connection so a small delay at least is
          required.
       c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that
          it is never 0 while a connection has been attempted, else
          the doubling will produce 0 and there will be no backoff.
       d/ to double is value (up to a limit) when delaying a connection,
          thus providing exponential backoff and
       e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation.
      
      So you can see it is highly dependant on xs_tcp_state_change being
      called as expected.  However experimental evidence shows that
      xs_tcp_state_change does not see all state changes.
      ("rpcdebug -m rpc trans" can help show what actually happens).
      
      Results show:
       TCP_ESTABLISHED is reported when a connection is made.  TCP_SYN_SENT
       is never reported, so rule 'c' above is never effective.
      
       When the server closes the connection, TCP_CLOSE_WAIT and
       TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always
       reported.  This rule 'b' above will sometimes be effective, but
       not reliably.
      
       When the client closes the connection, it used to result in
       TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE.  However since commit
       f75e6745 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on
       reconnect) we don't see *any* events on client-close.  I think this
       is because xs_restore_old_callbacks is called to disconnect
       xs_tcp_state_change before the socket is closed.
       In any case, rule 'a' no longer applies.
      
      So all that is left are rule d, which successfully doubles the
      timeout which is never rest, and rule e which initialises the timeout.
      
      Even if the rules worked as expected, there would be a problem because
      a successful connection does not reset the timeout, so a sequence
      of events where the server closes the connection (e.g. during failover
      testing) will cause longer and longer timeouts with no good reason.
      
      This patch:
      
       - sets reestablish_timeout to 0 in xs_close thus effecting rule 'a'
       - sets it to 0 in xs_tcp_data_ready to ensure that a successful
         connection resets the timeout
       - sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,
         thus effecting rule c
      
      I have not reimplemented rule b and the new version of rule c
      seems sufficient.
      
      I suspect other code in xs_tcp_data_ready needs to be revised as well.
      For example I don't think connect_cookie is being incremented as often
      as it should be.

      KEYS: Have the garbage collector set its timer for live expired keys · 606531c3
      David Howells authored
      The key garbage collector sets a timer to start a new collection cycle at the
      point the earliest key to expire should be considered garbage.  However, it
      currently only does this if the key it is considering hasn't yet expired.
      
      If the key being considering has expired, but hasn't yet reached the collection
      time then it is ignored, and won't be collected until some other key provokes a
      round of collection.
      
      Make the garbage collector set the timer for the earliest key that hasn't yet
      passed its collection time, rather than the earliest key that hasn't yet
      expired.

      9p: Add fscache support to 9p · 60e78d2c
      Abhishek Kulkarni authored
      This patch adds a persistent, read-only caching facility for
      9p clients using the FS-Cache caching backend.
      
      When the fscache facility is enabled, each inode is associated
      with a corresponding vcookie which is an index into the FS-Cache
      indexing tree. The FS-Cache indexing tree is indexed at 3 levels:
      - session object associated with each mount.
      - inode/vcookie
      - actual data (pages)
      
      A cache tag is chosen randomly for each session. These tags can
      be read off /sys/fs/9p/caches and can be passed as a mount-time
      parameter to re-attach to the specified caching session.

      Abhishek Kulkarni authored
      When using the cache=loose flags, the inode's size was not being
      updated correctly on a remote write. Thus subsequent reads of
      the whole file resulted in a truncated read. Fix it.
