      This is a corner case where less than MSS sized new data thingie
      is awaiting in the send queue. For F-RTO to work correctly, a
      new data segment must be sent at certain point or F-RTO cannot
      be used at all. RFC4138 allows overriding of Nagle at that
      point.

      when Nagle override is needed.

      [XFRM]: Restrict upper layer information by bundle. · 157bfc25
      Masahide NAKAMURA 提交于
      On MIPv6 usage, XFRM sub policy is enabled.
      When main (IPsec) and sub (MIPv6) policy selectors have the same
      address set but different upper layer information (i.e. protocol
      number and its ports or type/code), multiple bundle should be created.
      However, currently we have issue to use the same bundle created for
      the first time with all flows covered by the case.
      
      It is useful for the bundle to have the upper layer information
      to be restructured correctly if it does not match with the flow.
      
      1. Bundle was created by two policies
      Selector from another policy is added to xfrm_dst.
      If the flow does not match the selector, it goes to slow path to
      restructure new bundle by single policy.
      
      2. Bundle was created by one policy
      Flow cache is added to xfrm_dst as originated one. If the flow does
      not match the cache, it goes to slow path to try searching another
      policy.

      [TCP]: Catch skb with S+L bugs earlier · 34588b4c
      Ilpo Järvinen 提交于
      SACKED_ACKED and LOST are mutually exclusive with SACK, thus
      having their sum larger than packets_out is bug with SACK.
      Eventually these bugs trigger traps in the tcp_clean_rtx_queue
      with SACK but it's much more informative to do this here.
      
      Non-SACK TCP, however, could get more than packets_out duplicate
      ACKs which each increment sacked_out, so it makes sense to do
      this kind of limitting for non-SACK TCP but not for SACK enabled
      one. Perhaps the author had the opposite in mind but did the
      logic accidently wrong way around? Anyway, the sacked_out
      incrementer code for non-SACK already deals this issue before
      calling sync_left_out so this trapping can be done
      unconditionally.

      [PATCH] INET : IPV4 UDP lookups converted to a 2 pass algo · 6aaf47fa
      Eric Dumazet 提交于
      Some people want to have many UDP sockets, binded to a single port but
      many different addresses. We currently hash all those sockets into a
      single chain.  Processing of incoming packets is very expensive,
      because the whole chain must be examined to find the best match.
      
      I chose in this patch to hash UDP sockets with a hash function that
      take into account both their port number and address : This has a
      drawback because we need two lookups : one with a given address, one
      with a wildcard (null) address.

      Currently we scale the mempool sizes depending on memory installed
      in the machine, except for the bio pool itself which sits at a fixed
      256 entry pre-allocation.
      
      There's really no point in "optimizing" this OOM path, we just need
      enough preallocated to make progress. A single unit is enough, lets
      scale it down to 2 just to be on the safe side.

      cfq-iosched: get rid of cfqq hash · 91fac317
      Vasily Tarasov 提交于
      cfq hash is no more necessary.  We always can get cfqq from io context.
      cfq_get_io_context_noalloc() function is introduced, because we don't
      want to allocate cic on merging and checking may_queue.  In order to
      identify sync queue we've used hash key = CFQ_KEY_ASYNC. Since hash is
      eliminated we need to use other criterion: sync flag for queue is added.
      In all places where we dig in rb_tree we're in current context, so no
      additional locking is required.
      
      Advantages of this patch: no additional memory for hash, no seeking in
      hash, code is cleaner. But it is necessary now to seek cic in per-ioc
      rbtree, but it is faster:
      - most processes work only with few devices
      - most systems have only few block devices
      - it is a rb-tree

        than 0 or 1.

      - Fix bug where only bio_sync() is used, we need to check for a READ too
