       "We only have one urgent fix this time.
      
        Commit 3105f234 ("thermal/powerclamp: correct cpu support check"),
        which is shipped in 4.9-rc3, fixed a problem introduced by commit
        b721ca0d ("thermal/powerclamp: remove cpu whitelist").
      
        But unfortunately, it broke intel_powerclamp driver module auto-
        loading at the same time. Thus we need this change to add back module
        auto-loading for 4.9"

      NFSv4.x: hide array-bounds warning · d55b352b
      Arnd Bergmann authored
      A correct bugfix introduced a harmless warning that shows up with gcc-7:
      
      fs/nfs/callback.c: In function 'nfs_callback_up':
      fs/nfs/callback.c:214:14: error: array subscript is outside array bounds [-Werror=array-bounds]
      
      What happens here is that the 'minorversion == 0' check tells the
      compiler that we assume minorversion can be something other than 0,
      but when CONFIG_NFS_V4_1 is disabled that would be invalid and
      result in an out-of-bounds access.
      
      The added check for IS_ENABLED(CONFIG_NFS_V4_1) tells gcc that this
      really can't happen, which makes the code slightly smaller and also
      avoids the warning.
      
      The bugfix that introduced the warning is marked for stable backports,
      we want this one backported to the same releases.

      perf/x86/intel/uncore: Allow only a single PMU/box within an events group · 033ac60c
      Peter Zijlstra authored
      Group validation expects all events to be of the same PMU; however
      is_uncore_pmu() is too wide, it matches _all_ uncore events, even
      across PMUs.
      
      This triggers failure when we group different events from different
      uncore PMUs, like:
      
        perf stat -vv -e '{uncore_cbox_0/config=0x0334/,uncore_qpi_0/event=1/}' -a sleep 1
      
      Fix is_uncore_pmu() by only matching events to the box at hand.
      
      Note that generic code; ran after this step; will disallow this
      mixture of PMU events.

      perf/x86/intel: Cure bogus unwind from PEBS entries · b8000586
      Peter Zijlstra authored
      Vince Weaver reported that perf_fuzzer + KASAN detects that PEBS event
      unwinds sometimes do 'weird' things. In particular, we seemed to be
      ending up unwinding from random places on the NMI stack.
      
      While it was somewhat expected that the event record BP,SP would not
      match the interrupt BP,SP in that the interrupt is strictly later than
      the record event, it was overlooked that it could be on an already
      overwritten stack.
      
      Therefore, don't copy the recorded BP,SP over the interrupted BP,SP
      when we need stack unwinds.
      
      Note that its still possible the unwind doesn't full match the actual
      event, as its entirely possible to have done an (I)RET between record
      and interrupt, but on average it should still point in the general
      direction of where the event came from. Also, it's the best we can do,
      considering.
      
      The particular scenario that triggered the bogus NMI stack unwind was
      a PEBS event with very short period, upon enabling the event at the
      tail of the PMI handler (FREEZE_ON_PMI is not used), it instantly
      triggers a record (while still on the NMI stack) which in turn
      triggers the next PMI. This then causes back-to-back NMIs and we'll
      try and unwind the stack-frame from the last NMI, which obviously is
      now overwritten by our own.

      perf/x86: Restore TASK_SIZE check on frame pointer · ae31fe51
      Johannes Weiner authored
      The following commit:
      
        75925e1a ("perf/x86: Optimize stack walk user accesses")
      
      ... switched from copy_from_user_nmi() to __copy_from_user_nmi() with a manual
      access_ok() check.
      
      Unfortunately, copy_from_user_nmi() does an explicit check against TASK_SIZE,
      whereas the access_ok() uses whatever the current address limit of the task is.
      
      We are getting NMIs when __probe_kernel_read() has switched to KERNEL_DS, and
      then see vmalloc faults when we access what looks like pointers into vmalloc
      space:

      sched/autogroup: Do not use autogroup->tg in zombie threads · 8e5bfa8c
      Oleg Nesterov authored
      Exactly because for_each_thread() in autogroup_move_group() can't see it
      and update its ->sched_task_group before _put() and possibly free().
      
      So the exiting task needs another sched_move_task() before exit_notify()
      and we need to re-introduce the PF_EXITING (or similar) check removed by
      the previous change for another reason.

      sched/autogroup: Fix autogroup_move_group() to never skip sched_move_task() · 18f649ef
      Oleg Nesterov authored
      The PF_EXITING check in task_wants_autogroup() is no longer needed. Remove
      it, but see the next patch.
      
      However the comment is correct in that autogroup_move_group() must always
      change task_group() for every thread so the sysctl_ check is very wrong;
      we can race with cgroups and even sys_setsid() is not safe because a task
      running with task_group() == ag->tg must participate in refcounting:
      
      	int main(void)
      	{
      		int sctl = open("/proc/sys/kernel/sched_autogroup_enabled", O_WRONLY);
      
      		assert(sctl > 0);
      		if (fork()) {
      			wait(NULL); // destroy the child's ag/tg
      			pause();
      		}
      
      		assert(pwrite(sctl, "1\n", 2, 0) == 2);
      		assert(setsid() > 0);
      		if (fork())
      			pause();
      
      		kill(getppid(), SIGKILL);
      		sleep(1);
      
      		// The child has gone, the grandchild runs with kref == 1
      		assert(pwrite(sctl, "0\n", 2, 0) == 2);
      		assert(setsid() > 0);
      
      		// runs with the freed ag/tg
      		for (;;)
      			sleep(1);
      
      		return 0;
      	}
      
      crashes the kernel. It doesn't really need sleep(1), it doesn't matter if
      autogroup_move_group() actually frees the task_group or this happens later.

       1) With modern networking cards we can run out of 32-bit DMA space, so
          support 64-bit DMA addressing when possible on sparc64. From Dave
          Tushar.
      
       2) Some signal frame validation checks are inverted on sparc32, fix
          from Andreas Larsson.
      
       3) Lockdep tables can get too large in some circumstances on sparc64,
          add a way to adjust the size a bit. From Babu Moger.
      
       4) Fix NUMA node probing on some sun4v systems, from Thomas Tai.

       1) Clear congestion control state when changing algorithms on an
          existing socket, from Florian Westphal.
      
       2) Fix register bit values in altr_tse_pcs portion of stmmac driver,
          from Jia Jie Ho.
      
       3) Fix PTP handling in stammc driver for GMAC4, from Giuseppe
          CAVALLARO.
      
       4) Fix udplite multicast delivery handling, it ignores the udp_table
          parameter passed into the lookups, from Pablo Neira Ayuso.
      
       5) Synchronize the space estimated by rtnl_vfinfo_size and the space
          actually used by rtnl_fill_vfinfo. From Sabrina Dubroca.
      
       6) Fix memory leak in fib_info when splitting nodes, from Alexander
          Duyck.
      
       7) If a driver does a napi_hash_del() explicitily and not via
          netif_napi_del(), it must perform RCU synchronization as needed. Fix
          this in virtio-net and bnxt drivers, from Eric Dumazet.
      
       8) Likewise, it is not necessary to invoke napi_hash_del() is we are
          also doing neif_napi_del() in the same code path. Remove such calls
          from be2net and cxgb4 drivers, also from Eric Dumazet.

          from WANG Cong.
      
      14) Link dump filtering by master device and kind support added an error
          in loop index updates during the dump if we actually do filter, fix
          from Zhang Shengju.

      tcp: zero ca_priv area when switching cc algorithms · 7082c5c3
      Florian Westphal authored
      We need to zero out the private data area when application switches
      connection to different algorithm (TCP_CONGESTION setsockopt).
      
      When congestion ops get assigned at connect time everything is already
      zeroed because sk_alloc uses GFP_ZERO flag.  But in the setsockopt case
      this contains whatever previous cc placed there.

      net: l2tp: Treat NET_XMIT_CN as success in l2tp_eth_dev_xmit · 7c6ae610
      Gao Feng authored
      The tc could return NET_XMIT_CN as one congestion notification, but
      it does not mean the packe is lost. Other modules like ipvlan,
      macvlan, and others treat NET_XMIT_CN as success too.
      So l2tp_eth_dev_xmit should add the NET_XMIT_CN check.
