      [PATCH] x86_64: fix syscall/signal restart bug · 0233f53f
      Andi Kleen authored
      Fix a pretty bad bug that caused sometimes signals on x86-64
      to be restarted like system calls. This corrupted the RIP and
      in general caused undesirable effects.
      
      The problem happens because orig_rax is unsigned on x86-64,
      but it originally was signed when the signal code was written.
      And the if (orig_rax >= 0) ended up always true.
      And gcc didn't warn about this, because the warning is only in 
      -Wextra. 
      
      In 2.4 we still had a cast for it, but somehow it got dropped
      in 2.5.
      
      Credit goes to John Slice for tracking it down and Erich Boleyn
      for the original fix. All blame to me. I fixed it at another
      place too.

      [PKT_SCHED]: Provide compat policer stats in action policer · 59b17c27
      Thomas Graf authored
      This should go in before 2.6.10. It fixes a forgotten case to provide
      police backward compatibility statistics for old iproute2 versions
      running on a new kernel with actions enabled. Should make distributions
      happy with older iproute2 versions and all-included kernel configs
      since they probably favour actions over plain policer.
      
      Testing results:
        iproute2-2.4.7 on 2.6.10-rc3-bk8:
        cls-police: police creation succeeded
        cls-police: Sending 10 ICMP echo requests
        cls-police: police dumping succeeded with output:
        filter protocol ip pref 10 u32 
        filter protocol ip pref 10 u32 fh 800: ht divisor 1 
        filter protocol ip pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 10:12 
        police 3 action drop rate 2Kbit burst 10Kb mtu 2Kb 
          match 00010000/00ff0000 at 8
         Sent 420 bytes 10 pkts (dropped 0, overlimits 0)  <-- This would have been missing
        cls-police: police deletion succeeded
      
       iproute2-2.6.9 on 2.6.10-rc3-bk8:
       ...
        filter protocol ip pref 10 u32 
        filter protocol ip pref 10 u32 fh 800: ht divisor 1 
        filter protocol ip pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 10:12  (rule hit 10 success 10)
          match 00010000/00ff0000 at 8 (success 10 ) 
         police 0x4 rate 2000bit burst 10Kb mtu 2Kb action drop 
        ref 1 bind 1
         Sent 420 bytes 10 pkts (dropped 0, overlimits 0) 
       ...
      
       (Same results for fw classifier)

      [PKT_SCHED]: Fix double locking in tcindex destroy path. · ee6fa69b
      Thomas Graf authored
      tcindex's destroy uses its own delete functions to destroy its
      configuration. The delete function (correctly) takes the qdisc_tree_lock
      to prevent list walkings from happening while removing from the list.
      The qdisc_tree_lock is already held if we're comming via the destroy
      path and thus a double locking takes place.
