[ANNOUNCE] v4.11.12-rt11v4.11.12-rt11-patches

Dear RT folks!

I'm pleased to announce the v4.11.12-rt11 patch set.

Changes since v4.11.12-rt10:

  - Jacek Konieczny reported a lockdep splat of tcp_sk_lock vs softirq.

  - Mike Galbraith fixed a lockdep splat in the zcomp driver.

  - Mike Galbraith reported a locking problem in hrtimer during CPU
    hotplug.

Known issues
	- There was a report regarding a deadlock within the rtmutex code.

The delta patch against v4.11.12-rt10 is appended below and can be found here:

     https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.11/incr/patch-4.11.12-rt10-rt11.patch.xz

You can get this release via the git tree at:

+ in preemptible code
+
+Use get_local_ptr() instead this_cpu_ptr() to avoid a warning regarding
+smp_processor_id() in preemptible code.
+raw_cpu_ptr() would be fine, too because the per-CPU data structure is
+protected with a spin lock so it does not matter much if we take the
+other one.

+Subject: [PATCH] kernel/hrtimer: don't wakeup a process while holding the
+ hrtimer base lock
+
+We must not wake any process (and thus acquire the pi->lock) while
+holding the hrtimer's base lock. This does not happen usually because
+the hrtimer-callback is invoked in IRQ-context and so
+raise_softirq_irqoff() does not wakeup a process.
+However during CPU-hotplug it might get called from hrtimers_dead_cpu()
+which would wakeup the thread immediately.

+Subject: [PATCH] net: take the tcp_sk_lock lock with BH disabled
+
+Lockdep may complain about an unsafe locking scenario:
+|      CPU0                    CPU1
+|      ----                    ----
+| lock((tcp_sk_lock).lock);
+|                              lock(&per_cpu(local_softirq_locks[i], __cpu).lock);
+|                              lock((tcp_sk_lock).lock);
+| lock(&per_cpu(local_softirq_locks[i], __cpu).lock);
+
+in the call paths:
+	do_current_softirqs -> tcp_v4_send_ack()
+vs
+	tcp_v4_send_reset -> do_current_softirqs().
+
+This should not happen since local_softirq_locks is per CPU. Reversing
+the order makes lockdep happy.
