      bpf jit: Make the filter.c::__load_pointer helper non-static for the jits · f03fb3f4
      Jan Seiffert 提交于
      The function is renamed to make it a little more clear what it does.
      It is not added to any .h because it is not for general consumption, only for
      bpf internal use (and so by the jits).

      TCP: update ip_local_port_range documentation · 5d6bd861
      Fernando Luis Vazquez Cao 提交于
      The explanation of ip_local_port_range in
      Documentation/networking/ip-sysctl.txt contains several factual
      errors:
      
      - The default value of ip_local_port_range does not depend on the
        amount of memory available in the system.
      - tcp_tw_recycle is not enabled by default.
      - 1024-4999 is not the default value.
      - Etc.

      tcp: allow splice() to build full TSO packets · 2f533844
      Eric Dumazet 提交于
      vmsplice()/splice(pipe, socket) call do_tcp_sendpages() one page at a
      time, adding at most 4096 bytes to an skb. (assuming PAGE_SIZE=4096)
      
      The call to tcp_push() at the end of do_tcp_sendpages() forces an
      immediate xmit when pipe is not already filled, and tso_fragment() try
      to split these skb to MSS multiples.
      
      4096 bytes are usually split in a skb with 2 MSS, and a remaining
      sub-mss skb (assuming MTU=1500)
      
      This makes slow start suboptimal because many small frames are sent to
      qdisc/driver layers instead of big ones (constrained by cwnd and packets
      in flight of course)
      
      In fact, applications using sendmsg() (adding an additional memory copy)
      instead of vmsplice()/splice()/sendfile() are a bit faster because of
      this anomaly, especially if serving small files in environments with
      large initial [c]wnd.
      
      Call tcp_push() only if MSG_MORE is not set in the flags parameter.
      
      This bit is automatically provided by splice() internals but for the
      last page, or on all pages if user specified SPLICE_F_MORE splice()
      flag.
      
      In some workloads, this can reduce number of sent logical packets by an
      order of magnitude, making zero-copy TCP actually faster than
      one-copy :)

      ppp: Don't stop and restart queue on every TX packet · e675f0cc
      David Woodhouse 提交于
      For every transmitted packet, ppp_start_xmit() will stop the netdev
      queue and then, if appropriate, restart it. This causes the TX softirq
      to run, entirely gratuitously.
      
      This is "only" a waste of CPU time in the normal case, but it's actively
      harmful when the PPP device is a TEQL slave — the wakeup will cause the
      offending device to receive the next TX packet from the TEQL queue, when
      it *should* have gone to the next slave in the list. We end up seeing
      large bursts of packets on just *one* slave device, rather than using
      the full available bandwidth over all slaves.
      
      This patch fixes the problem by *not* unconditionally stopping the queue
      in ppp_start_xmit(). It adds a return value from ppp_xmit_process()
      which indicates whether the queue should be stopped or not.
      
      It *doesn't* remove the call to netif_wake_queue() from
      ppp_xmit_process(), because other code paths (especially from
      ppp_output_wakeup()) need it there and it's messy to push it out to the
      other callers to do it based on the return value. So we leave it in
      place — it's a no-op in the case where the queue wasn't stopped, so it's
      harmless in the TX path.

      net: fix /proc/net/dev regression · 2def16ae
      Eric Dumazet 提交于
      Commit f04565dd (dev: use name hash for dev_seq_ops) added a second
      regression, as some devices are missing from /proc/net/dev if many
      devices are defined.
      
      When seq_file buffer is filled, the last ->next/show() method is
      canceled (pos value is reverted to value prior ->next() call)
      
      Problem is after above commit, we dont restart the lookup at right
      position in ->start() method.
      
      Fix this by removing the internal 'pos' pointer added in commit, since
      we need to use the 'loff_t *pos' provided by seq_file layer.
      
      This also reverts commit 5cac98dd (net: Fix corruption
      in /proc/*/net/dev_mcast), since its not needed anymore.

       "This pull just contains a forward of the Intel fixes from Daniel.
      
        The only annoyance is the RC6 enable, which really should have made
        -next, but since Ubuntu are shipping it I reckon its getting a good
        testing now by the time 3.4 comes out.
      
        The pull from Daniel contains his pull message to me:
      
          "A few patches for 3.4, major part is 3 regression fixes:
           - ppgtt broke hibernate on snb/ivb.  Somehow our QA claims that it
             still works, which is why this has not been caught earlier.
           - ppgtt flails in combination with dmar.  I kinda expected this one :(
           - fence handling bugfix for gen2/3.  Iirc this one is about a year

           Wrt regressions I've just got a report that gmbus (newly enabled

           Also included are the rc6 enable patches for snb from Eugeni.  I
           wanted to include these in the main 3.4 pull but screwed it up.
           Please hit me.  Imo these kind of patches really should go in
           before -rc1, but in thise case rc6 has brought us tons of press and
           guinea pigs^W^W testers and ubuntu is already running with it.  So
           I estimate a pretty small chance for this to blow up.

            - sprite fix from Jesse"
      
      Let's see if the "enable RC6 on sandybridge" finally works and sticks.
      I've been enabling it by hand (i915.i915_enable_rc6=1) for several
      months on my Macbook Air, and it definitely makes a difference (and has
      worked for me).  But every time we enabled it before it showed some odd
      hw buglet for *somebody*.
      
      This time it's all good, I'm sure.

      drm: Validate requested virtual size against allocated fb size · 62fb376e
      Chris Wilson 提交于
      mplayer -vo fbdev tries to create a screen that is twice as tall as the
      allocated framebuffer for "doublebuffering". By default, and all in-tree
      users, only sufficient memory is allocated and mapped to satisfy the
      smallest framebuffer and the virtual size is no larger than the actual.
      For these users, we should therefore reject any userspace request to
      create a screen that requires a buffer larger than the framebuffer
      originally allocated.

      remained an include.
      
      There were no build regressions since all consumers were already getting

      Commit b4816afa ("Move the asm-generic/system.h xchg()

      asm/cmpxchg.h but the parisc arch never got one.  Fork the cmpxchg
      content out of the asm/atomic.h file to create one.
      
      Some minor whitespace fixups were done on the block of code that created
      the new file.

      avr32: fix build failures from mis-naming of atmel_nand.h · 3d92e051
      Paul Gortmaker 提交于
      Commit bf4289cb ("ATMEL: fix nand ecc support") indicated that it
      wanted to "Move platform data to a common header
      include/linux/platform_data/atmel_nand.h" and the new header even had
      re-include protectors with:
      
          #ifndef __ATMEL_NAND_H__
      
      However, the file that was added was simply called atmel.h
      and this caused avr32 defconfig to fail with:
      
        In file included from arch/avr32/boards/atstk1000/setup.c:22:
        arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory

        make[2]: *** [arch/avr32/boards/atstk1000/setup.o] Error 1
      
      It seems the scope of the file contents will expand beyond
      just nand, so ignore the original intention, and fix up the
      users who reference the bad name with the _nand suffix.
