      Pull networking fixes from David Miller:
       "Bug fixes galore, mostly in drivers as is often the case:
      
        1) USB gadget and cdc_eem drivers need adjustments to their frame size
           lengths in order to handle VLANs correctly.  From Ian Coolidge.
      
        2) TIPC and several network drivers erroneously call tasklet_disable
           before tasklet_kill, fix from Xiaotian Feng.
      
        3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
           fix from Cyril Brulebois.
      
        4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
           Nathan Walp.
      
        5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
           zero.  From John Fastabend.
      
        6) Fix smsc95xx tx checksum offload on big-endian, from Steve
           Glendinning.
      
        7) __inet_diag_dump() needs to repsect and report the error value
           returned from inet_diag_lock_handler() rather than ignore it.
           Otherwise if an inet diag handler is not available for a particular
           protocol, we essentially report success instead of giving an error
           indication.  Fix from Cyrill Gorcunov.
      
        8) When the QFQ packet scheduler sees TSO/GSO packets it does not
           handle things properly, and in fact ends up corrupting it's
           datastructures as well as mis-schedule packets.  Fix from Paolo
           Valente.
      
        9) Fix oopser in skb_loop_sk(), from Eric Leblond.
      
        10) CXGB4 passes partially uninitialized datastructures in to FW
            commands, fix from Vipul Pandya.
      
        11) When we send unsolicited ipv6 neighbour advertisements, we should
            send them to the link-local allnodes multicast address, as per
            RFC4861.  Fix from Hannes Frederic Sowa.
      
        12) There is some kind of bug in the usbnet's kevent deferral
            mechanism, but more immediately when it triggers an uncontrolled
            stream of kernel messages spam the log.  Rate limit the error log
            message triggered when this problem occurs, as sending thousands
            of error messages into the kernel log doesn't help matters at all,
            and in fact makes further diagnosis more difficult.
      
            From Steve Glendinning.
      
        13) Fix gianfar restore from hibernation, from Wang Dongsheng.
      
        14) The netlink message attribute sizes are wrong in the ipv6 GRE
            driver, it was using the size of ipv4 addresses instead of ipv6
            ones :-) Fix from Nicolas Dichtel."

      Pull sparc fixes from David Miller:
       "Several build/bug fixes for sparc, including:
      
        1) Configuring a mix of static vs.  modular sparc64 crypto modules
           didn't work, remove an ill-conceived attempt to only have to build
           the device match table for these drivers once to fix the problem.
      
           Reported by Meelis Roos.
      
        2) Make the montgomery multiple/square and mpmul instructions actually
           usable in 32-bit tasks.  Essentially this involves providing 32-bit
           userspace with a way to use a 64-bit stack when it needs to.
      
        3) Our sparc64 atomic backoffs don't yield cpu strands properly on
           Niagara chips.  Use pause instruction when available to achieve
           this, otherwise use a benign instruction we know blocks the strand
           for some time.
      
        4) Wire up kcmp
      
        5) Fix the build of various drivers by removing the unnecessary
           blocking of OF_GPIO when SPARC.
      
        6) Fix unintended regression wherein of_address_to_resource stopped
           being provided.  Fix from Andreas Larsson.
      
        7) Fix NULL dereference in leon_handle_ext_irq(), also from Andreas

      Andrew Morton 提交于
      Revert commit 03a7beb5 ("epoll: support for disabling items, and a
      self-test app") pending resolution of the issues identified by Michael
      Kerrisk, copied below.
      
      We'll revisit this for 3.8.
      
      : I've taken a look at this patch as it currently stands in 3.7-rc1, and
      : done a bit of testing. (By the way, the test program
      : tools/testing/selftests/epoll/test_epoll.c does not compile...)
      :
      : There are one or two places where the behavior seems a little strange,
      : so I have a question or two at the end of this mail. But other than
      : that, I want to check my understanding so that the interface can be
      : correctly documented.
      :
      : Just to go though my understanding, the problem is the following
      : scenario in a multithreaded application:
      :
      : 1. Multiple threads are performing epoll_wait() operations,
      :    and maintaining a user-space cache that contains information
      :    corresponding to each file descriptor being monitored by
      :    epoll_wait().
      :
      : 2. At some point, a thread wants to delete (EPOLL_CTL_DEL)
      :    a file descriptor from the epoll interest list, and
      :    delete the corresponding record from the user-space cache.
      :
      : 3. The problem with (2) is that some other thread may have
      :    previously done an epoll_wait() that retrieved information
      :    about the fd in question, and may be in the middle of using
      :    information in the cache that relates to that fd. Thus,
      :    there is a potential race.
      :
      : 4. The race can't solved purely in user space, because doing
      :    so would require applying a mutex across the epoll_wait()
      :    call, which would of course blow thread concurrency.
      :
      : Right?
      :
      : Your solution is the EPOLL_CTL_DISABLE operation. I want to
      : confirm my understanding about how to use this flag, since
      : the description that has accompanied the patches so far
      : has been a bit sparse
      :
      : 0. In the scenario you're concerned about, deleting a file
      :    descriptor means (safely) doing the following:
      :    (a) Deleting the file descriptor from the epoll interest list
      :        using EPOLL_CTL_DEL
      :    (b) Deleting the corresponding record in the user-space cache
      :
      : 1. It's only meaningful to use this EPOLL_CTL_DISABLE in
      :    conjunction with EPOLLONESHOT.
      :
      : 2. Using EPOLL_CTL_DISABLE without using EPOLLONESHOT in
      :    conjunction is a logical error.
      :
      : 3. The correct way to code multithreaded applications using
      :    EPOLL_CTL_DISABLE and EPOLLONESHOT is as follows:
      :
      :    a. All EPOLL_CTL_ADD and EPOLL_CTL_MOD operations should
      :       should EPOLLONESHOT.
      :
      :    b. When a thread wants to delete a file descriptor, it
      :       should do the following:
      :
      :       [1] Call epoll_ctl(EPOLL_CTL_DISABLE)
      :       [2] If the return status from epoll_ctl(EPOLL_CTL_DISABLE)
      :           was zero, then the file descriptor can be safely
      :           deleted by the thread that made this call.
      :       [3] If the epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY,
      :           then the descriptor is in use. In this case, the calling
      :           thread should set a flag in the user-space cache to
      :           indicate that the thread that is using the descriptor
      :           should perform the deletion operation.
      :
      : Is all of the above correct?
      :
      : The implementation depends on checking on whether
      : (events & ~EP_PRIVATE_BITS) == 0
      : This replies on the fact that EPOLL_CTL_AD and EPOLL_CTL_MOD always
      : set EPOLLHUP and EPOLLERR in the 'events' mask, and EPOLLONESHOT
      : causes those flags (as well as all others in ~EP_PRIVATE_BITS) to be
      : cleared.
      :
      : A corollary to the previous paragraph is that using EPOLL_CTL_DISABLE
      : is only useful in conjunction with EPOLLONESHOT. However, as things
      : stand, one can use EPOLL_CTL_DISABLE on a file descriptor that does
      : not have EPOLLONESHOT set in 'events' This results in the following
      : (slightly surprising) behavior:
      :
      : (a) The first call to epoll_ctl(EPOLL_CTL_DISABLE) returns 0
      :     (the indicator that the file descriptor can be safely deleted).
      : (b) The next call to epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY.
      :
      : This doesn't seem particularly useful, and in fact is probably an
      : indication that the user made a logic error: they should only be using
      : epoll_ctl(EPOLL_CTL_DISABLE) on a file descriptor for which
      : EPOLLONESHOT was set in 'events'. If that is correct, then would it
      : not make sense to return an error to user space for this case?

      checkpatch: improve network block comment style checking · c24f9f19
      Joe Perches 提交于
      Some comment styles in net and drivers/net are flagged inappropriately.
      
      Avoid proclaiming inline comments like:
      	int a = b;	/* some comment */
      and block comments like:
      	/*********************
      	 * some comment
      	 ********************/
      are defective.
      
      Tested with
      $ cat drivers/net/t.c
      /* foo */
      
      /*
       * foo
       */
      
      /* foo
       */
      
      /* foo
       * bar */
      
      /****************************
       * some long block comment
       ***************************/
      
      struct foo {
      	int bar;	/* another test */
      };
