      tcp: Change possible SYN flooding messages · 946cedcc
      Eric Dumazet 提交于
      "Possible SYN flooding on port xxxx " messages can fill logs on servers.
      
      Change logic to log the message only once per listener, and add two new
      SNMP counters to track :
      
      TCPReqQFullDoCookies : number of times a SYNCOOKIE was replied to client
      
      TCPReqQFullDrop : number of times a SYN request was dropped because
      syncookies were not enabled.
      
      Based on a prior patch from Tom Herbert, and suggestions from David.

      snmp: 64bit ipstats_mib for all arches · 4ce3c183
      Eric Dumazet 提交于
      /proc/net/snmp and /proc/net/netstat expose SNMP counters.
      
      Width of these counters is either 32 or 64 bits, depending on the size
      of "unsigned long" in kernel.
      
      This means user program parsing these files must already be prepared to
      deal with 64bit values, regardless of user program being 32 or 64 bit.
      
      This patch introduces 64bit snmp values for IPSTAT mib, where some
      counters can wrap pretty fast if they are 32bit wide.

      percpu: add __percpu sparse annotations to net · 7d720c3e
      Tejun Heo 提交于
      Add __percpu sparse annotations to net.
      
      These annotations are to make sparse consider percpu variables to be
      in a different address space and warn if accessed without going
      through percpu accessors.  This patch doesn't affect normal builds.
      
      The macro and type tricks around snmp stats make things a bit
      interesting.  DEFINE/DECLARE_SNMP_STAT() macros mark the target field
      as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
      snmp_mib_*() users which used to cast the argument to (void **) are
      updated to cast it to (void __percpu **).

      [UDP]: Revert udplite and code split. · db8dac20
      David S. Miller 提交于
      This reverts commit db1ed684 ("[IPV6]
      UDP: Rename IPv6 UDP files."), commit
      8be8af8f ("[IPV4] UDP: Move
      IPv4-specific bits to other file.") and commit
      e898d4db ("[UDP]: Allow users to
      configure UDP-Lite.").
      
      First, udplite is of such small cost, and it is a core protocol just
      like TCP and normal UDP are.
      
      We spent enormous amounts of effort to make udplite share as much code
      with core UDP as possible.  All of that work is less valuable if we're
      just going to slap a config option on udplite support.
      
      It is also causing build failures, as reported on linux-next, showing
      that the changeset was not tested very well.  In fact, this is the
      second build failure resulting from the udplite change.
      
      Finally, the config options provided was a bool, instead of a modular
      option.  Meaning the udplite code does not even get build tested
      by allmodconfig builds, and furthermore the user is not presented
      with a reasonable modular build option which is particularly needed
      by distribution vendors.
