+
+Properly verify that the resulting page aligned end address is larger
+than both the start address and the length of the memory area
+requested.
+
+Both the start and length arguments for ib_umem_get are controlled by
+the user. A misbehaving user can provide values which will cause an
+integer overflow when calculating the page aligned end address.
+
+This overflow can cause also miscalculation of the number of pages
+mapped, and additional logic issues.

+A local route may have a lower hop_limit set than global routes do.
+
+RFC 3756, Section 4.2.7, "Parameter Spoofing"
+
+>   1.  The attacker includes a Current Hop Limit of one or another small
+>       number which the attacker knows will cause legitimate packets to
+>       be dropped before they reach their destination.
+
+>   As an example, one possible approach to mitigate this threat is to
+>   ignore very small hop limits.  The nodes could implement a
+>   configurable minimum hop limit, and ignore attempts to set it below
+>   said limit.

+The timeout entries are sizeof(int) rather than sizeof(long), which

+Origin: https://git.kernel.org/linus/db27ebb111e9f69efece08e4cb6a34ff980f8896
+
+Max unacked packets/bytes is an int while sizeof(long) was used in the
+sysctl table.
+
+This means that when they were getting read we'd also leak kernel memory
+to userspace along with the timeout values.

+Origin: https://git.kernel.org/linus/223b02d923ecd7c84cf9780bb3686f455d279279
+
+"len" contains sizeof(nf_ct_ext) and size of extensions. In a worst
+case it can contain all extensions. Bellow you can find sizes for all
+types of extensions. Their sum is definitely bigger than 256.
+
+nf_ct_ext_types[0]->len = 24
+nf_ct_ext_types[1]->len = 32
+nf_ct_ext_types[2]->len = 24
+nf_ct_ext_types[3]->len = 32
+nf_ct_ext_types[4]->len = 152
+nf_ct_ext_types[5]->len = 2
+nf_ct_ext_types[6]->len = 16
+nf_ct_ext_types[7]->len = 8
+
+I have seen "len" up to 280 and my host has crashes w/o this patch.
+
+The right way to fix this problem is reducing the size of the ecache
+extension (4) and Florian is going to do this, but these changes will
+be quite large to be appropriate for a stable tree.

+Otherwise the guest can abuse that control to cause e.g. PCIe
+Unsupported Request responses by disabling memory and/or I/O decoding
+and subsequently causing (CPU side) accesses to the respective address
+ranges, which (depending on system configuration) may be fatal to the

+
+Note that to alter any of the bits collected together as
+PCI_COMMAND_GUEST permissive mode is now required to be enabled

+Origin: https://git.kernel.org/linus/956421fbb74c3a6261903f3836c0740187cf038b
+
+'ret_from_fork' checks TIF_IA32 to determine whether 'pt_regs' and
+the related state make sense for 'ret_from_sys_call'.  This is
+entirely the wrong check.  TS_COMPAT would make a little more
+sense, but there's really no point in keeping this optimization
+at all.
+
+This fixes a return to the wrong user CS if we came from int
+0x80 in a 64-bit task.

 IRQF_NO_THREAD. So it's safe to allow force threaded handlers.

 Assigning mask = tsk_cpus_allowed(p) after p->migrate_disable = 0 ensures
 that we won't see a mask change.. no push/pull, we stack tasks on one CPU.

 The migrate_disable() can cause a bit of a overhead to the RT kernel,
 as changing the affinity is expensive to do at every lock encountered.

 The reader_lock is mostly taken in normal context with interrupts enabled.
 But because ftrace_dump() can happen anywhere, it is used as a spin lock

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=312efc77b378e864095f37b12a3d23ca5fa3702c
+
+qdisc_lock is taken w/o disabling interrupts or bottom halfs. So code
+holding a qdisc_lock() can be interrupted and softirqs can run on the
+return of interrupt in !RT.
+
+The spin_trylock() in net_tx_action() makes sure, that the softirq
+does not deadlock. When the lock can't be acquired q is requeued and
+the NET_TX softirq is raised. That causes the softirq to run over and
+over.
+
+That works in mainline as do_softirq() has a retry loop limit and
+leaves the softirq processing in the interrupt return path and
+schedules ksoftirqd. The task which holds qdisc_lock cannot be
+preempted, so the lock is released and either ksoftirqd or the next
+softirq in the return from interrupt path can proceed. Though it's a
+bit strange to actually run MAX_SOFTIRQ_RESTART (10) loops before it
+decides to bail out even if it's clear in the first iteration :)
+
+On RT all softirq processing is done in a FIFO thread and we don't
+have a loop limit, so ksoftirqd preempts the lock holder forever and
+unqueues and requeues until the reset button is hit.
+
+Due to the forced threading of ksoftirqd on RT we actually cannot
+deadlock on qdisc_lock because it's a "sleeping lock". So it's safe to
+replace the spin_trylock() with a spin_lock(). When contended,
+ksoftirqd is scheduled out and the lock holder can proceed.

+To work around this in the short term you can use this patch, in

+switch (if there are any in use of course), this should be esp easy now
+that we have a kmap_atomic stack.
+
+Something like the below.. it wants replacing all the preempt_disable()
+stuff with pagefault_disable() && migrate_disable() of course, but then
+you can flip kmaps around like below.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=c9d49a094abb638129cd0457a4d6d4d97f76dcec
+
+Current sysv sems have a weird ass wakeup scheme that involves keeping
+preemption disabled over a potential O(n^2) loop and busy waiting on
+that on other CPUs.
+
+Kill this and simply wake the task directly from under the sem_lock.
+
+This was discovered by a migrate_disable() debug feature that
+disallows:
+
+  spin_lock();
+  preempt_disable();
+  spin_unlock()
+  preempt_enable();

+ PREEMPT_RT_FULL
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=fa48df972a5f4217742f282e262e4277ff63cc0a
+
+Add a CONFIG option to allow the output from Magic SysRq to be output
+immediately, even if this causes large latencies.
+
+If PREEMPT_RT_FULL, printk() will not try to acquire the console lock
+when interrupts or preemption are disabled.  If the console lock is
+not acquired the printk() output will be buffered, but will not be
+output immediately. Some drivers call into the Magic SysRq code
+with interrupts or preemption disabled, so the output of Magic SysRq
+will be buffered instead of printing immediately if this option is
+not selected.
+
+Even with this option selected, Magic SysRq output will be delayed
+if the attempt to acquire the console lock fails.

+
+Restrict the preempt disabled regions to the actual floating point
+operations and enable preemption for the administrative actions.
+
+This is necessary on RT to avoid that kfree and other operations are
+called with preemption disabled.

+
+If a low prio writer gets preempted while holding the seqlock write
+locked, a high prio reader spins forever on RT.
+
+To prevent this let the reader grab the spinlock, so it blocks and
+eventually boosts the writer. This way the writer can proceed and
+endless spinning is prevented.
+
+For seqcount writers we disable preemption over the update code
+path. Thaanks to Al Viro for distangling some VFS code to make that
+possible.

+    timers: fix timer hotplug on -rt
+
+    Here we are in the CPU_DEAD notifier, and we must not sleep nor
+    enable interrupts.
+
+There's no problem with sleeping in this notifier.
+
+But the get_cpu_var() had to be converted to a get_local_var().
+
+Replace the previous fix with the get_local_var() convert.

+
+When taking the pi_lock, we must disable interrupts because the
+pi_lock can also be taken in an interrupt handler.
+
+Use raw_spin_lock_irq() instead of raw_spin_lock().

+In RT the reader lock is a mutex and we can not grab it when preemption is

+
+The wait_task_interactive() will have a task sleep waiting for another
+task to have a certain state. But it ignores the rt_spin_locks state
+and can return with an incorrect result if the task it is waiting
+for is blocked on a rt_spin_lock() and is waking up.
+
+The rt_spin_locks save the tasks state in the saved_state field
+and the wait_task_interactive() must also test that state.

+Subject: [PATCH 253/371] lglock/rt: Use non-rt for_each_cpu() in -rt code
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=31de6ffe05ee8c78795baff36f0bd24f5ea1588c
+
+Currently the RT version of the lglocks() does a for_each_online_cpu()
+in the name##_global_lock_online() functions. Non-rt uses its own
+mask for this, and for good reason.
+
+A task may grab a *_global_lock_online(), and in the mean time, one
+of the CPUs goes offline. Now when that task does a *_global_unlock_online()
+it releases all the locks *except* the one that went offline.
+
+Now if that CPU were to come back on line, its lock is now owned by a
+task that never released it when it should have.
+
+This causes all sorts of fun errors. Like owners of a lock no longer
+existing, or sleeping on IO, waiting to be woken up by a task that
+happens to be blocked on the lock it never released.
+
+Convert the RT versions to use the lglock specific cpumasks. As once
+a CPU comes on line, the mask is set, and never cleared even when the
+CPU goes offline. The locks for that CPU will still be taken and released.

+
+Tasks can block on hotplug.lock in pin_current_cpu(), but their state
+might be != RUNNING. So the mutex wakeup will set the state
+unconditionally to RUNNING. That might cause spurious unexpected
+wakeups. We could provide a state preserving mutex_lock() function,
+but this is semantically backwards. So instead we convert the
+hotplug.lock() to a spinlock for RT, which has the state preserving
+semantics already.

+
+raise_softirq_irqoff() disables interrupts and wakes the softirq
+daemon, but after reenabling interrupts there is no preemption check,
+so the execution of the softirq thread might be delayed arbitrarily.
+
+In principle we could add that check to local_irq_enable/restore, but
+that's overkill as the rasie_softirq_irqoff() sections are the only
+ones which show this behaviour.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b435f7fbed5fa57d5a5025271a09267f73d0b94f
+
+Retry loops on RT might loop forever when the modifying side was
+preempted. Add cpu_chill() to replace cpu_relax(). cpu_chill()
+defaults to cpu_relax() for non RT. On RT it puts the looping task to
+sleep for a tick so the preempted task can make progress.

+Subject: [PATCH 262/371] scsi: qla2xxx: Use local_irq_save_nort() in
+ qla2x00_poll
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2d4c6cb9671b79a6d974862f27ad88a392cc0e58
+
+RT triggers the following:
+
+[   11.307652]  [<ffffffff81077b27>] __might_sleep+0xe7/0x110
+[   11.307663]  [<ffffffff8150e524>] rt_spin_lock+0x24/0x60
+[   11.307670]  [<ffffffff8150da78>] ? rt_spin_lock_slowunlock+0x78/0x90
+[   11.307703]  [<ffffffffa0272d83>] qla24xx_intr_handler+0x63/0x2d0 [qla2xxx]
+[   11.307736]  [<ffffffffa0262307>] qla2x00_poll+0x67/0x90 [qla2xxx]
+
+Function qla2x00_poll does local_irq_save() before calling qla24xx_intr_handler
+which has a spinlock. Since spinlocks are sleepable on rt, it is not allowed
+to call them with interrupts disabled. Therefore we use local_irq_save_nort()
+instead which saves flags without disabling interrupts.
+
+This fix needs to be applied to v3.0-rt, v3.2-rt and v3.4-rt

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=57b7ee3b92d9174abde8ce045f7d95b9fdc6e4bc
+
+1)enqueue_to_backlog() (called from netif_rx) should be
+  bind to a particluar CPU. This can be achieved by
+  disabling migration. No need to disable preemption
+
+2)Fixes crash "BUG: scheduling while atomic: ksoftirqd"
+  in case of RT.
+  If preemption is disabled, enqueue_to_backog() is called
+  in atomic context. And if backlog exceeds its count,
+  kfree_skb() is called. But in RT, kfree_skb() might
+  gets scheduled out, so it expects non atomic context.
+
+3)When CONFIG_PREEMPT_RT_FULL is not defined,
+ migrate_enable(), migrate_disable() maps to
+ preempt_enable() and preempt_disable(), so no
+ change in functionality in case of non-RT.
+
+-Replace preempt_enable(), preempt_disable() with
+ migrate_enable(), migrate_disable() respectively
+-Replace get_cpu(), put_cpu() with get_cpu_light(),
+ put_cpu_light() respectively

+Subject: [PATCH 265/371] Latency histogramms: Cope with backwards running
+ local trace clock
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=dbdb52b031e4be9b3c18eff24bf82b20fb6d48f9
+
+Thanks to the wonders of modern technology, the local trace clock can
+now run backwards. Since this never happened before, the time difference
+between now and somewhat earlier was expected to never become negative
+and, thus, stored in an unsigned integer variable. Nowadays, we need a
+signed integer to ensure that the value is stored as underflow in the
+related histogram. (In cases where this is not a misfunction, bipolar
+histograms can be used.)
+
+This patch takes care that all latency variables are represented as
+signed integers and negative numbers are considered as histogram
+underflows.
+
+In one of the misbehaving processors switching to global clock solved
+the problem:

+Subject: [PATCH 266/371] Latency histograms: Adjust timer, if already elapsed
+ when programmed
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b73352ae32ed61ff4955949ff9f574edf74b05e1
+
+Nothing prevents a programmer from calling clock_nanosleep() with an
+already elapsed wakeup time in absolute time mode or with a too small
+delay in relative time mode. Such timers cannot wake up in time and,
+thus, should be corrected when entered into the missed timers latency
+histogram (CONFIG_MISSED_TIMERS_HIST).
+
+This patch marks such timers and uses a corrected expiration time.

+
+While waiting for an RT process to be woken up, the previous process may
+go to wait and switch to another one with the same priority which then
+becomes current. This condition was not correctly recognized and led to
+erroneously high latency recordings during periods of low CPU load.
+
+This patch correctly marks such latencies as sharedprio and prevents
+them from being recorded as actual system latency.

+
+On RT we avoid the cross cpu function calls and take the per cpu local
+locks instead. Now the code missed that taking the local lock on the
+cpu which runs the code must use the proper local lock functions and
+not a simple spin_lock(). Otherwise it deadlocks later when trying to
+acquire the local lock with the proper function.

+Subject: [PATCH 272/371] cpu/rt: Rework cpu down for PREEMPT_RT
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=81d561fd4d6cdbdec8c2fe64ec7c0198b0a72d3e
+
+Bringing a CPU down is a pain with the PREEMPT_RT kernel because
+tasks can be preempted in many more places than in non-RT. In
+order to handle per_cpu variables, tasks may be pinned to a CPU
+for a while, and even sleep. But these tasks need to be off the CPU
+if that CPU is going down.
+
+Several synchronization methods have been tried, but when stressed
+they failed. This is a new approach.
+
+A sync_tsk thread is still created and tasks may still block on a
+lock when the CPU is going down, but how that works is a bit different.
+When cpu_down() starts, it will create the sync_tsk and wait on it
+to inform that current tasks that are pinned on the CPU are no longer
+pinned. But new tasks that are about to be pinned will still be allowed
+to do so at this time.
+
+Then the notifiers are called. Several notifiers will bring down tasks
+that will enter these locations. Some of these tasks will take locks
+of other tasks that are on the CPU. If we don't let those other tasks
+continue, but make them block until CPU down is done, the tasks that
+the notifiers are waiting on will never complete as they are waiting
+for the locks held by the tasks that are blocked.
+
+Thus we still let the task pin the CPU until the notifiers are done.
+After the notifiers run, we then make new tasks entering the pinned
+CPU sections grab a mutex and wait. This mutex is now a per CPU mutex
+in the hotplug_pcp descriptor.
+
+To help things along, a new function in the scheduler code is created
+called migrate_me(). This function will try to migrate the current task
+off the CPU this is going down if possible. When the sync_tsk is created,
+all tasks will then try to migrate off the CPU going down. There are
+several cases that this wont work, but it helps in most cases.
+
+After the notifiers are called and if a task can't migrate off but enters
+the pin CPU sections, it will be forced to wait on the hotplug_pcp mutex
+until the CPU down is complete. Then the scheduler will force the migration
+anyway.
+
+Also, I found that THREAD_BOUND need to also be accounted for in the
+pinned CPU, and the migrate_disable no longer treats them special.
+This helps fix issues with ksoftirqd and workqueue that unbind on CPU down.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b65d962b3b8a03072b29cb564b01eb79e4c5861f
+
+The commit "cpu/rt: Rework cpu down for PREEMPT_RT" changed the double
+meaning of the cpu_hotplug.lock, where it was a spinlock for RT and a
+mutex for non-RT, to just a mutex for both.  But the initialization of
+the variable was not updated to reflect this change.

+Subject: [PATCH 274/371] time/rt: Fix up leap-second backport for RT changes
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=0a489b839cb3d8b9aa51d61ac97a9014db8f8540
+
+The leap-second backport broke RT, and a few changes had to be done.
+
+1) The second_overflow now encompasses ntp_leap_second, and since
+second_overflow is called with the xtime_lock held, we can not take that
+lock either.
+
+2) Change ktime_get_update_offsets() to use read_seqcount_begin() instead
+of read_seq_begin() (and retry).

+Subject: [PATCH 275/371] fix printk flush of messages
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=5a2447c21aaaa68e752caa426fa28546868860b3
+
+Updates console-make-rt-friendly.patch
+
+#ifdef CONFIG_PREEMPT_RT_FULL, printk() output is never flushed by
+printk() because:
+
+   # some liberties taken in this pseudo-code to make it easier to follow
+   printk()
+      vprintk()
+         raw_spin_lock(&logbuf_lock)
+            # increment preempt_count():
+            preempt_disable()
+      result = console_trylock_for_printk()
+         retval = 0
+         # lock will always be false, because preempt_count() will be >= 1
+         lock = ... && !preempt_count()
+         if (lock)
+            retval = 1
+         return retval
+      # result will always be false since lock will always be false
+      if (result)
+         console_unlock()
+            # this is where the printk() output would be flushed
+
+On system boot some printk() output is flushed because register_console()
+and tty_open() call console_unlock().
+
+This change also fixes the problem that was previously fixed by
+preempt-rt-allow-immediate-magic-sysrq-output-for-preempt_rt_full.patch

+The rtmutex_common.h:75 is:
+
+rt_mutex_top_waiter(struct rt_mutex *lock)
+{
+	struct rt_mutex_waiter *w;
+
+	w = plist_first_entry(&lock->wait_list, struct rt_mutex_waiter,
+			       list_entry);
+	BUG_ON(w->lock != lock);
+
+	return w;
+}
+
+Where the waiter->lock is corrupted. I saw various other random bugs
+that all had to with the softirq lock and plist. As plist needs to be
+initialized before it is used I investigated how this lock is
+initialized. It's initialized with:
+
+void __init softirq_early_init(void)
+{
+	local_irq_lock_init(local_softirq_lock);
+}
+
+Where:
+
+#define local_irq_lock_init(lvar)					\
+	do {								\
+		int __cpu;						\
+		for_each_possible_cpu(__cpu)				\
+			spin_lock_init(&per_cpu(lvar, __cpu).lock);	\
+	} while (0)
+
+As the softirq lock is a local_irq_lock, which is a per_cpu lock, the
+initialization is done to all per_cpu versions of the lock. But lets
+look at where the softirq_early_init() is called from.
+
+In init/main.c: start_kernel()
+
+/*
+ * Interrupts are still disabled. Do necessary setups, then
+ * enable them
+ */
+	softirq_early_init();
+	tick_init();
+	boot_cpu_init();
+	page_address_init();
+	printk(KERN_NOTICE "%s", linux_banner);
+	setup_arch(&command_line);
+	mm_init_owner(&init_mm, &init_task);
+	mm_init_cpumask(&init_mm);
+	setup_command_line(command_line);
+	setup_nr_cpu_ids();
+	setup_per_cpu_areas();
+	smp_prepare_boot_cpu();	/* arch-specific boot-cpu hooks */
+
+One of the first things that is called is the initialization of the
+softirq lock. But if you look further down, we see the per_cpu areas
+have not been set up yet. Thus initializing a local_irq_lock() before
+the per_cpu section is set up, may not work as it is initializing the
+per cpu locks before the per cpu exists.
+
+By moving the softirq_early_init() right after setup_per_cpu_areas(),
+the kernel boots fine.

+
+If the stop machinery is called from inactive CPU we cannot use
+mutex_lock, because some other stomp machine invokation might be in
+progress and the mutex can be contended. We cannot schedule from this
+context, so trylock and loop.

+Subject: [PATCH 289/371] sched: Queue RT tasks to head when prio drops
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=cfefd751f42bc26fb370516c7c118a920b80b4f9
+
+The following scenario does not work correctly:
+
+Runqueue of CPUx contains two runnable and pinned tasks:
+ T1: SCHED_FIFO, prio 80
+ T2: SCHED_FIFO, prio 80
+
+T1 is on the cpu and executes the following syscalls (classic priority
+ceiling scenario):
+
+ sys_sched_setscheduler(pid(T1), SCHED_FIFO, .prio = 90);
+ ...
+ sys_sched_setscheduler(pid(T1), SCHED_FIFO, .prio = 80);
+ ...
+
+Now T1 gets preempted by T3 (SCHED_FIFO, prio 95). After T3 goes back
+to sleep the scheduler picks T2. Surprise!
+
+The same happens w/o actual preemption when T1 is forced into the
+scheduler due to a sporadic NEED_RESCHED event. The scheduler invokes
+pick_next_task() which returns T2. So T1 gets preempted and scheduled
+out.
+
+This happens because sched_setscheduler() dequeues T1 from the prio 90
+list and then enqueues it on the tail of the prio 80 list behind T2.
+This violates the POSIX spec and surprises user space which relies on
+the guarantee that SCHED_FIFO tasks are not scheduled out unless they
+give the CPU up voluntarily or are preempted by a higher priority
+task. In the latter case the preempted task must get back on the CPU
+after the preempting task schedules out again.
+
+We fixed a similar issue already in commit 60db48c (sched: Queue a
+deboosted task to the head of the RT prio queue). The same treatment
+is necessary for sched_setscheduler(). So enqueue to head of the prio
+bucket list if the priority of the task is lowered.
+
+It might be possible that existing user space relies on the current
+behaviour, but it can be considered highly unlikely due to the corner
+case nature of the application scenario.

+Subject: [PATCH 290/371] sched: Consider pi boosting in setscheduler
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=a9b75465c8d654d6b7024415292d9a548b41e616
+
+If a PI boosted task policy/priority is modified by a setscheduler()
+call we unconditionally dequeue and requeue the task if it is on the
+runqueue even if the new priority is lower than the current effective
+boosted priority. This can result in undesired reordering of the
+priority bucket list.
+
+If the new priority is less or equal than the current effective we
+just store the new parameters in the task struct and leave the
+scheduler class and the runqueue untouched. This is handled when the
+task deboosts itself. Only if the new priority is higher than the
+effective boosted priority we apply the change immediately.

+
+As the acpi code disables interrupts in acpi_idle_enter_bm, and calls
+code that grabs the acpi lock, it causes issues as the lock is currently
+in RT a sleeping lock.
+
+The lock was converted from a raw to a sleeping lock due to some
+previous issues, and tests that showed it didn't seem to matter.
+Unfortunately, it did matter for one of our boxes.
+
+This patch converts the lock back to a raw lock. I've run this code on a
+few of my own machines, one being my laptop that uses the acpi quite
+extensively. I've been able to suspend and resume without issues.

+Subject: [PATCH 298/371] serial: Imx: Fix recursive locking bug
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=225e23914f882db96fa47764834b016c61b2d888
+
+commit 9ec1882df2 (tty: serial: imx: console write routing is unsafe
+on SMP) introduced a recursive locking bug in imx_console_write().
+
+The callchain is:
+
+imx_rxint()
+  spin_lock_irqsave(&sport->port.lock,flags);
+  ...
+  uart_handle_sysrq_char();
+    sysrq_function();
+      printk();
+        imx_console_write();
+          spin_lock_irqsave(&sport->port.lock,flags); <--- DEAD
+
+The bad news is that the kernel debugging facilities can dectect the
+problem, but the printks never surface on the serial console for
+obvious reasons.
+
+There is a similar issue with oops_in_progress. If the kernel crashes
+we really don't want to be stuck on the lock and unable to tell what
+happened.
+
+In general most UP originated drivers miss these checks and nobody
+ever notices because CONFIG_PROVE_LOCKING seems to be still ignored by
+a large number of developers.
+
+The solution is to avoid locking in the sysrq case and trylock in the
+oops_in_progress case.
+
+This scheme is used in other drivers as well and it would be nice if
+we could move this to a common place, so the usual copy/paste/modify
+bugs can be avoided.
+
+Now there is another issue with this scheme:
+
+CPU0 	    	     	 CPU1
+printk()
+			 rxint()
+			   sysrq_detection() -> sets port->sysrq
+			 return from interrupt
+  console_write()
+     if (port->sysrq)
+     	avoid locking
+
+port->sysrq is reset with the next receive character. So as long as
+the port->sysrq is not reset and this can take an endless amount of
+time if after the break no futher receive character follows, all
+console writes happen unlocked.
+
+While the current writer is protected against other console writers by
+the console sem, it's unprotected against open/close or other
+operations which fiddle with the port. That's what the above mentioned
+commit tried to solve.
+
+That's an issue in all drivers which use that scheme and unfortunately
+there is no easy workaround. The only solution is to have a separate
+indicator port->sysrq_cpu. uart_handle_sysrq_char() then sets it to
+smp_processor_id() before calling into handle_sysrq() and resets it to
+-1 after that. Then change the locking check to:
+
+     if (port->sysrq_cpu == smp_processor_id())
+     	 locked = 0;
+     else if (oops_in_progress)
+         locked = spin_trylock_irqsave(port->lock, flags);
+     else
+  	 spin_lock_irqsave(port->lock, flags);
+
+That would force all other cpus into the spin_lock path. Problem
+solved, but that's way beyond the scope of this fix and really wants
+to be implemented in a common function which calls the uart specific
+write function to avoid another gazillion of hard to debug
+copy/paste/modify bugs.

+
+wait_queue is a swiss army knife and in most of the cases the
+complexity is not needed. For RT waitqueues are a constant source of
+trouble as we can't convert the head lock to a raw spinlock due to
+fancy and long lasting callbacks.
+
+Provide a slim version, which allows RT to replace wait queues. This
+should go mainline as well, as it lowers memory consumption and
+runtime overhead.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b9614715cdde96bf8ba832b914e5ac0cee812f27
+
+We had a customer report a lockup on a 3.0-rt kernel that had the
+following backtrace:
+
+[ffff88107fca3e80] rt_spin_lock_slowlock at ffffffff81499113
+[ffff88107fca3f40] rt_spin_lock at ffffffff81499a56
+[ffff88107fca3f50] __wake_up at ffffffff81043379
+[ffff88107fca3f80] mce_notify_irq at ffffffff81017328
+[ffff88107fca3f90] intel_threshold_interrupt at ffffffff81019508
+[ffff88107fca3fa0] smp_threshold_interrupt at ffffffff81019fc1
+[ffff88107fca3fb0] threshold_interrupt at ffffffff814a1853
+
+It actually bugged because the lock was taken by the same owner that
+already had that lock. What happened was the thread that was setting
+itself on a wait queue had the lock when an MCE triggered. The MCE
+interrupt does a wake up on its wait list and grabs the same lock.
+
+NOTE: THIS IS NOT A BUG ON MAINLINE
+
+Sorry for yelling, but as I Cc'd mainline maintainers I want them to
+know that this is an PREEMPT_RT bug only. I only Cc'd them for advice.
+
+On PREEMPT_RT the wait queue locks are converted from normal
+"spin_locks" into an rt_mutex (see the rt_spin_lock_slowlock above).
+These are not to be taken by hard interrupt context. This usually isn't
+a problem as most all interrupts in PREEMPT_RT are converted into
+schedulable threads. Unfortunately that's not the case with the MCE irq.
+
+As wait queue locks are notorious for long hold times, we can not
+convert them to raw_spin_locks without causing issues with -rt. But
+Thomas has created a "simple-wait" structure that uses raw spin locks
+which may have been a good fit.
+
+Unfortunately, wait queues are not the only issue, as the mce_notify_irq
+also does a schedule_work(), which grabs the workqueue spin locks that
+have the exact same issue.
+
+Thus, this patch I'm proposing is to move the actual work of the MCE
+interrupt into a helper thread that gets woken up on the MCE interrupt
+and does the work in a schedulable context.
+
+NOTE: THIS PATCH ONLY CHANGES THE BEHAVIOR WHEN PREEMPT_RT IS SET
+
+Oops, sorry for yelling again, but I want to stress that I keep the same
+behavior of mainline when PREEMPT_RT is not set. Thus, this only changes
+the MCE behavior when PREEMPT_RT is configured.

+Subject: [PATCH 303/371] swap: Use unique local lock name for swap_lock
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=7aa4af2d9ded88b0803fe80c0c7f792c6cfd2aa2
+
+From lib/Kconfig.debug on CONFIG_FORCE_WEAK_PER_CPU:
+
+----
+s390 and alpha require percpu variables in modules to be
+defined weak to work around addressing range issue which
+puts the following two restrictions on percpu variable
+definitions.
+
+1. percpu symbols must be unique whether static or not
+2. percpu variables can't be defined inside a function
+
+To ensure that generic code follows the above rules, this
+option forces all percpu variables to be defined as weak.
+----
+
+The addition of the local IRQ swap_lock in mm/swap.c broke this config
+as the name "swap_lock" is used through out the kernel. Just do a "git
+grep swap_lock" to see, and the new swap_lock is a local lock which
+defines the swap_lock for per_cpu.
+
+The fix was to rename swap_lock to swapvec_lock which keeps it unique.

+
+Commit 908a3283 (Fix idle_cpu()) invalidated some uses of idle_cpu(),
+which used to say whether or not the CPU was running the idle task,
+but now instead says whether or not the CPU is running the idle task
+in the absence of pending wakeups.  Although this new implementation
+gives a better answer to the question "is this CPU idle?", it also
+invalidates other uses that were made of idle_cpu().
+
+This commit therefore introduces a new is_idle_task() API member
+that determines whether or not the specified task is one of the
+idle tasks, allowing open-coded "->pid == 0" sequences to be replaced
+by something more meaningful.

+
+In -rt, most spin_locks() turn into mutexes. One of these spin_lock
+conversions is performed on the workqueue gcwq->lock. When the idle
+worker is worken, the first thing it will do is grab that same lock and
+it too will block, possibly jumping into the same code, but because
+nr_running would already be decremented it prevents an infinite loop.
+
+But this is still a waste of CPU cycles, and it doesn't follow the method
+of mainline, as new workers should only be woken when a worker thread is
+truly going to sleep, and not just blocked on a spin_lock().
+
+Check the saved_state too before waking up new workers.

+
+When a threaded irq handler is installed the irq thread is initially
+created on normal scheduling priority. Only after the irq thread is
+woken up it sets its priority to RT_FIFO MAX_USER_RT_PRIO/2 itself.
+
+This means that interrupts that occur directly after the irq handler
+is installed will be handled on a normal scheduling priority instead
+of the realtime priority that one would expect.
+
+Fix this by setting the RT priority on creation of the irq_thread.

+
+As per changes in include/linux/jbd_common.h for avoiding the
+bit_spin_locks on RT ("fs: jbd/jbd2: Make state lock and journal
+head lock rt safe") we do the same thing here.
+
+We use the non atomic __set_bit and __clear_bit inside the scope of
+the lock to preserve the ability of the existing LIST_DEBUG code to
+use the zero'th bit in the sanity checks.
+
+As a bit spinlock, we had no lockdep visibility into the usage
+of the list head locking.  Now, if we were to implement it as a
+standard non-raw spinlock, we would see:

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=aea3274a79bedab25963f0caec93ba84c9425e1b
+
+The patch "list_bl.h: make list head locking RT safe" introduced
+an unconditional
+
+	__set_bit(0, (unsigned long *)b);
+
+in void hlist_bl_lock(struct hlist_bl_head *b). This clobbers the value
+of b->first. When the value of b->first is retrieved using
+hlist_bl_first the clobbering is undone using
+
+	(unsigned long)h->first & ~LIST_BL_LOCKMASK
+
+and so depending on LIST_BL_LOCKMASK being one. But LIST_BL_LOCKMASK is
+only one if at least on of CONFIG_SMP and CONFIG_DEBUG_SPINLOCK are
+defined. Without these the value returned by hlist_bl_first has the
+zeroth bit set which likely results in a crash.
+
+So only do the clobbering in the cases where LIST_BL_LOCKMASK is one.
+An alternative would be to always define LIST_BL_LOCKMASK to one with
+CONFIG_PREEMPT_RT_BASE.

+Subject: [PATCH 311/371] kernel/cpu: fix cpu down problem if kthread's cpu is
+ going down
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=24a2a3f7b21070a9b4dc5b3e2d8448b4a86ae25a
+
+If kthread is pinned to CPUx and CPUx is going down then we get into
+trouble:
+- first the unplug thread is created
+- it will set itself to hp->unplug. As a result, every task that is
+  going to take a lock, has to leave the CPU.
+- the CPU_DOWN_PREPARE notifier are started. The worker thread will
+  start a new process for the "high priority worker".
+  Now kthread would like to take a lock but since it can't leave the CPU
+  it will never complete its task.
+
+We could fire the unplug thread after the notifier but then the cpu is
+no longer marked "online" and the unplug thread will run on CPU0 which
+was fixed before :)
+
+So instead the unplug thread is started and kept waiting until the
+notfier complete their work.

+If a task which is allowed to run only on CPU X puts CPU Y down then it

+
+The ntp code for notify_cmos_timer() is called from a hard interrupt
+context. schedule_delayed_work() under PREEMPT_RT_FULL calls spinlocks
+that have been converted to mutexes, thus calling schedule_delayed_work()
+from interrupt is not safe.
+
+Add a helper thread that does the call to schedule_delayed_work and wake
+up that thread instead of calling schedule_delayed_work() directly.
+This is only for CONFIG_PREEMPT_RT_FULL, otherwise the code still calls
+schedule_delayed_work() directly in irq context.
+
+Note: There's a few places in the kernel that do this. Perhaps the RT
+code should have a dedicated thread that does the checks. Just register
+a notifier on boot up for your check and wake up the thread when
+needed. This will be a todo.

+Subject: [PATCH 315/371] hwlat-detector: Update hwlat_detector to add outer
+ loop detection
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2c3ba75d50da357d5b2eec45bd1975677bd1b152
+
+The hwlat_detector reads two timestamps in a row, then reports any
+gap between those calls. The problem is, it misses everything between
+the second reading of the time stamp to the first reading of the time stamp
+in the next loop. That's were most of the time is spent, which means,
+chances are likely that it will miss all hardware latencies. This
+defeats the purpose.
+
+By also testing the first time stamp from the previous loop second
+time stamp (the outer loop), we are more likely to find a latency.
+
+Setting the threshold to 1, here's what the report now looks like:
+
+1347415723.0232202770	0	2

+As ktime_get() calls into the timing code which does a read_seq(), it
+may be affected by other CPUS that touch that lock. To remove this
+dependency, use the trace_clock_local() which is already exported
+for module use. If CONFIG_TRACING is enabled, use that as the clock,
+otherwise use ktime_get().

+
+There's no reason to use stop machine to search for hardware latency.
+Simply disabling interrupts while running the loop will do enough to
+check if something comes in that wasn't disabled by interrupts being
+off, which is exactly what stop machine does.
+
+Instead of using stop machine, just have the thread disable interrupts
+while it checks for hardware latency.

+Subject: [PATCH 319/371] genirq: do not invoke the affinity callback via a
+ workqueue
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=b1650111200519c39ca9a9da858a3d0ffc1b113d
+
+Joe Korty reported, that __irq_set_affinity_locked() schedules a
+workqueue while holding a rawlock which results in a might_sleep()
+warning.
+This patch moves the invokation into a process context so that we only
+wakeup() a process while holding the lock.

+ CAP_SYS_NICE
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2a6f6607fb0ce9d1a38c82e0a157903792e176c1
+
+In commit ee23871389 ("genirq: Set irq thread to RT priority on
+creation") we moved the assigment of the thread's priority from the
+thread's function into __setup_irq(). That function may run in user
+context for instance if the user opens an UART node and then driver
+calls requests in the ->open() callback. That user may not have
+CAP_SYS_NICE and so the irq thread won't run with the SCHED_OTHER
+policy.
+
+This patch uses sched_setscheduler_nocheck() so we omit the CAP_SYS_NICE
+check which is otherwise required for the SCHED_OTHER policy.

+Subject: [PATCH 324/371] cpu_down: move migrate_enable() back
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2185fee372179e9475a7f56edfb70e1389d56aa4
+
+Commit 08c1ab68, "hotplug-use-migrate-disable.patch", intends to
+use migrate_enable()/migrate_disable() to replace that combination
+of preempt_enable() and preempt_disable(), but actually in
+!CONFIG_PREEMPT_RT_FULL case, migrate_enable()/migrate_disable()
+are still equal to preempt_enable()/preempt_disable(). So that
+followed cpu_hotplug_begin()/cpu_unplug_begin(cpu) would go schedule()
+to trigger schedule_debug() like this:
+
+_cpu_down()
+	|
+	+ migrate_disable() = preempt_disable()
+	|
+	+ cpu_hotplug_begin() or cpu_unplug_begin()
+		|
+		+ schedule()
+			|
+			+ __schedule()
+				|
+				+ preempt_disable();
+				|
+				+ __schedule_bug() is true!
+
+So we should move migrate_enable() as the original scheme.

+The wait-simple queue is lighter weight and more efficient than the full
+wait queue, and may be used in atomic context on PREEMPT_RT.
+
+Fix up some places that needed to call the swait_*() functions instead
+of the wait_*() functions.

+Subject: [PATCH 326/371] lockdep: Correctly annotate hardirq context in
+ irq_exit()
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=d24d20c3727465870c3162197c3c8774449c968f
+
+There was a reported deadlock on -rt which lockdep didn't report.
+
+It turns out that in irq_exit() we tell lockdep that the hardirq
+context ends and then do all kinds of locking afterwards.
+
+To fix it, move trace_hardirq_exit() to the very end of irq_exit(), this
+ensures all locking in tick_irq_exit() and rcu_irq_exit() are properly
+recorded as happening from hardirq context.
+
+This however leads to the 'fun' little problem of running softirqs
+while in hardirq context. To cure this make the softirq code a little
+more complex (in the CONFIG_TRACE_IRQFLAGS case).
+
+Due to stack swizzling arch dependent trickery we cannot pass an
+argument to __do_softirq() to tell it if it was done from hardirq
+context or not; so use a side-band argument.
+
+When we do __do_softirq() from hardirq context, 'atomically' flip to
+softirq context and back, so that no locking goes without being in
+either hard- or soft-irq context.
+
+I didn't find any new problems in mainline using this patch, but it
+did show the -rt problem.

+lock_timer_base() does a try_lock() which deadlocks on the waiter lock
+not the lock itself.
+This patch takes the waiter_lock with trylock so it should work from interrupt
+context as well. If the fastpath doesn't work and the waiter_lock itself is
+taken then it seems that the lock itself taken.
+This patch also adds a "rt_spin_try_unlock" to keep lockdep happy. If we
+managed to take the wait_lock in the first place we should also be able
+to take it in the unlock path.

+Subject: [PATCH 328/371] smp: introduce a generic on_each_cpu_mask() function
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=d45efcb45cffa87cee8d5166a21afdcc49a0a3d9
+
+[ Upstream commit 3fc498f165304dc913f1d13b5ac9ab4c758ee7ab ]
+
+We have lots of infrastructure in place to partition multi-core systems
+such that we have a group of CPUs that are dedicated to specific task:
+cgroups, scheduler and interrupt affinity, and cpuisol= boot parameter.
+Still, kernel code will at times interrupt all CPUs in the system via IPIs
+for various needs.  These IPIs are useful and cannot be avoided
+altogether, but in certain cases it is possible to interrupt only specific
+CPUs that have useful work to do and not the entire system.
+
+This patch set, inspired by discussions with Peter Zijlstra and Frederic
+Weisbecker when testing the nohz task patch set, is a first stab at trying
+to explore doing this by locating the places where such global IPI calls
+are being made and turning the global IPI into an IPI for a specific group
+of CPUs.  The purpose of the patch set is to get feedback if this is the
+right way to go for dealing with this issue and indeed, if the issue is
+even worth dealing with at all.  Based on the feedback from this patch set
+I plan to offer further patches that address similar issue in other code
+paths.
+
+This patch creates an on_each_cpu_mask() and on_each_cpu_cond()
+infrastructure API (the former derived from existing arch specific
+versions in Tile and Arm) and uses them to turn several global IPI
+invocation to per CPU group invocations.
+
+Core kernel:
+
+on_each_cpu_mask() calls a function on processors specified by cpumask,
+which may or may not include the local processor.
+
+You must not call this function with disabled interrupts or from a
+hardware interrupt handler or from a bottom half handler.
+
+arch/arm:
+
+Note that the generic version is a little different then the Arm one:
+
+1. It has the mask as first parameter
+2. It calls the function on the calling CPU with interrupts disabled,
+   but this should be OK since the function is called on the other CPUs
+   with interrupts disabled anyway.
+
+arch/tile:
+
+The API is the same as the tile private one, but the generic version
+also calls the function on the with interrupts disabled in UP case
+
+This is OK since the function is called on the other CPUs
+with interrupts disabled.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=61a0b120ee7bde27d6201b62d553b81c6f653a71
+
+[ Upstream commit b3a7e98e024ffa9f7e4554dd720c508015c4a831 ]
+
+Add the on_each_cpu_cond() function that wraps on_each_cpu_mask() and
+calculates the cpumask of cpus to IPI by calling a function supplied as a
+parameter in order to determine whether to IPI each specific cpu.
+
+The function works around allocation failure of cpumask variable in
+CONFIG_CPUMASK_OFFSTACK=y by itereating over cpus sending an IPI a time
+via smp_call_function_single().
+
+The function is useful since it allows to seperate the specific code that
+decided in each case whether to IPI a specific cpu for a specific request
+from the common boilerplate code of handling creating the mask, handling
+failures etc.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=53366be4436dd9a6e579e9d6654c46a8d861c9e0
+
+[ Upstream commit 42be35d0390b966253136a285f507f5ad00fd9e8 ]
+
+In several code paths, such as when unmounting a file system (but not
+only) we send an IPI to ask each cpu to invalidate its local LRU BHs.
+
+For multi-cores systems that have many cpus that may not have any LRU BH
+because they are idle or because they have not performed any file system
+accesses since last invalidation (e.g.  CPU crunching on high perfomance
+computing nodes that write results to shared memory or only using
+filesystems that do not use the bh layer.) This can lead to loss of
+performance each time someone switches the KVM (the virtual keyboard and
+screen type, not the hypervisor) if it has a USB storage stuck in.
+
+This patch attempts to only send an IPI to cpus that have LRU BH.

+Subject: [PATCH 331/371] rcutree/rcu_bh_qs: disable irq while calling
+ rcu_preempt_qs()
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=4329ae698c01a5efa975a87a6f59888cea16da78
+
+Any callers to the function rcu_preempt_qs() must disable irqs in
+order to protect the assignment to ->rcu_read_unlock_special. In
+RT case, rcu_bh_qs() as the wrapper of rcu_preempt_qs() is called
+in some scenarios where irq is enabled, like this path,
+
+do_single_softirq()
+    |
+    + local_irq_enable();
+    + handle_softirq()
+    |    |
+    |    + rcu_bh_qs()
+    |        |
+    |        + rcu_preempt_qs()
+    |
+    + local_irq_disable()
+
+So here we'd better disable irq directly inside of rcu_bh_qs() to
+fix this, otherwise the kernel may be freezable sometimes as
+observed. And especially this way is also kind and safe for the
+potential rcu_bh_qs() usage elsewhere in the future.

+Subject: [PATCH 332/371] rt: Make cpu_chill() use hrtimer instead of msleep()
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=8286f3c02d62499ca53fa1eedb2b8b6bba5e3851
+
+Ulrich Obergfell pointed out that cpu_chill() calls msleep() which is woken
+up by the ksoftirqd running the TIMER softirq. But as the cpu_chill() is
+called from softirq context, it may block the ksoftirqd() from running, in
+which case, it may never wake up the msleep() causing the deadlock.
+
+I checked the vmcore, and irq/74-qla2xxx is stuck in the msleep() call,
+running on CPU 8. The one ksoftirqd that is stuck, happens to be the one that
+runs on CPU 8, and it is blocked on a lock held by irq/74-qla2xxx. As that
+ksoftirqd is the one that will wake up irq/74-qla2xxx, and it happens to be
+blocked on a lock that irq/74-qla2xxx holds, we have our deadlock.
+
+The solution is not to convert the cpu_chill() back to a cpu_relax() as that
+will re-create a possible live lock that the cpu_chill() fixed earlier, and may
+also leave this bug open on other softirqs. The fix is to remove the
+dependency on ksoftirqd from cpu_chill(). That is, instead of calling
+msleep() that requires ksoftirqd to wake it up, use the
+hrtimer_nanosleep() code that does the wakeup from hard irq context.
+
+|Looks to be the lock of the block softirq. I don't have the core dump
+|anymore, but from what I could tell the ksoftirqd was blocked on the
+|block softirq lock, where the block softirq handler did a msleep
+|(called by the qla2xxx interrupt handler).
+|
+|Looking at trigger_softirq() in block/blk-softirq.c, it can do a
+|smp_callfunction() to another cpu to run the block softirq. If that
+|happens to be the cpu where the qla2xx irq handler is doing the block
+|softirq and is in a middle of a msleep(), I believe the ksoftirqd will
+|try to run the softirq. If it does that, then BOOM, it's deadlocked
+|because the ksoftirqd will never run the timer softirq either.
+
+|I should have also stated that it was only one lock that was involved.
+|But the lock owner was doing a msleep() that requires a wakeup by
+|ksoftirqd to continue. If ksoftirqd happens to be blocked on a lock
+|held by the msleep() caller, then you have your deadlock.
+|
+|It's best not to have any softirqs going to sleep requiring another
+|softirq to wake it up. Note, if we ever require a timer softirq to do a
+|cpu_chill() it will most definitely hit this deadlock.

+This reverts commit 916c8d2de3c4759f57426fa3cfee63b491e88939.
+
+Seems that I was a bit too aggressive in backporting patches. I have

+for the modified files, as the updates used swait functionality that
+was not created in 3.2-rt.

+Subject: [PATCH 336/371] net: sched: dev_deactivate_many(): use msleep(1)
+ instead of yield() to wait for outstanding qdisc_run calls
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=4455764da9c070e3fd4a5a364dc5666cb460cc92
+
+On PREEMPT_RT enabled systems the interrupt handler run as threads at prio 50
+(by default). If a high priority userspace process tries to shut down a busy
+network interface it might spin in a yield loop waiting for the device to
+become idle. With the interrupt thread having a lower priority than the
+looping process it might never be scheduled and so result in a deadlock on UP
+systems.
+
+With Magic SysRq the following backtrace can be produced:
+

+
+This patch works around the problem by replacing yield() by msleep(1), giving
+the interrupt thread time to finish, similar to other changes contained in the
+rt patch set. Using wait_for_completion() instead would probably be a better
+solution.

+Two cps in parallel managed to stall the the ext4 fs. It seems that
+journal code is either waiting for locks or sleeping waiting for
+something to happen. This seems similar to what Mike observed on ext3,
+here is his description:
+
+|With an -rt kernel, and a heavy sync IO load, tasks can jam
+|up on journal locks without unplugging, which can lead to
+|terminal IO starvation.  Unplug and schedule when waiting

+Subject: [PATCH 338/371] cpu_chill: Add a UNINTERRUPTIBLE hrtimer_nanosleep
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=23bb58c5a8fd2d5b699c7c1244c597206539400a
+
+We hit another bug that was caused by switching cpu_chill() from
+msleep() to hrtimer_nanosleep().
+
+This time it is a livelock. The problem is that hrtimer_nanosleep()
+calls schedule with the state == TASK_INTERRUPTIBLE. But these means
+that if a signal is pending, the scheduler wont schedule, and will
+simply change the current task state back to TASK_RUNNING. This
+nullifies the whole point of cpu_chill() in the first place. That is,
+if a task is spinning on a try_lock() and it preempted the owner of the
+lock, if it has a signal pending, it will never give up the CPU to let
+the owner of the lock run.
+
+I made a static function __hrtimer_nanosleep() that takes a fifth
+parameter "state", which determines the task state of that the
+nanosleep() will be in. The normal hrtimer_nanosleep() will act the
+same, but cpu_chill() will call the __hrtimer_nanosleep() directly with
+the TASK_UNINTERRUPTIBLE state.
+
+cpu_chill() only cares that the first sleep happens, and does not care
+about the state of the restart schedule (in hrtimer_nanosleep_restart).

+
+each per-queue lock is taken with spin_lock_irqsave() except in the case
+where all of them are taken for some kind of serialisation. As an
+optimisation local_irq_save() is used so that lock_tx_qs() and
+lock_rx_qs() can use just the spin_lock() variant instead.
+On RT local_irq_save() behaves differently so we use the nort()
+variant.
+Lockdep screems easily by "ethtool -K eth0 rx off tx off"
+
+What remains is missing lockdep annotation that makes lockdep think
+lock_tx_qs() may cause a dead lock.

+Since it is no longer invoked from the softirq people run into OOM more
+often if the priority of the RCU thread is too low. Making boosting
+default on RT should help in those case and it can be switched off if

+ select_fallback_rq()
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=24d0abf473c1cf070877da5ecda9555de3f16175
+
+I talked with Peter Zijlstra about this, and he told me that the clearing
+of the PF_NO_SETAFFINITY flag was to deal with the optimization of
+migrate_disable/enable() that ignores tasks that have that flag set. But
+that optimization was removed when I did a rework of the cpu hotplug code.
+
+I found that ignoring tasks that had that flag set would cause those tasks
+to not sync with the hotplug code and cause the kernel to crash. Thus it
+needed to not treat them special and those tasks had to go though the same
+work as tasks without that flag set.
+
+Now that those tasks are not treated special, there's no reason to clear the
+flag.
+
+May still need to be tested as the migrate_me() code does not ignore those
+flags.

+Subject: [PATCH 343/371] workqueue: Prevent deadlock/stall on RT
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=c994575bef464c7c8cab68707003e5ba77cdc985
+
+Austin reported a XFS deadlock/stall on RT where scheduled work gets
+never exececuted and tasks are waiting for each other for ever.
+
+The underlying problem is the modification of the RT code to the
+handling of workers which are about to go to sleep. In mainline a
+worker thread which goes to sleep wakes an idle worker if there is
+more work to do. This happens from the guts of the schedule()
+function. On RT this must be outside and the accessed data structures
+are not protected against scheduling due to the spinlock to rtmutex
+conversion. So the naive solution to this was to move the code outside
+of the scheduler and protect the data structures by the pool
+lock. That approach turned out to be a little naive as we cannot call
+into that code when the thread blocks on a lock, as it is not allowed
+to block on two locks in parallel. So we dont call into the worker
+wakeup magic when the worker is blocked on a lock, which causes the
+deadlock/stall observed by Austin and Mike.
+
+Looking deeper into that worker code it turns out that the only
+relevant data structure which needs to be protected is the list of
+idle workers which can be woken up.
+
+So the solution is to protect the list manipulation operations with
+preempt_enable/disable pairs on RT and call unconditionally into the
+worker code even when the worker is blocked on a lock. The preemption
+protection is safe as there is nothing which can fiddle with the list
+outside of thread context.

+Subject: [PATCH 345/371] lockdep: Fix backport of "Correctly annotate hardirq
+ context in irq_exit()"
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=0d820fe104f13784a055925dd6ec6d7327087d53
+
+The backport of f1a83e652bed "lockdep: Correctly annotate hardirq context
+in irq_exit()" to v3.2.53-rt76 wasn't correct because v3.2-rt had two
+calls to invoke_softirq(). One when __ARCH_IRQ_EXIT_IRQS_DISABLED is defined
+and another when it is not defined. v3.14 which introduced this change
+only had one version.
+
+When I backported this change, I didn't see the two places and only one
+was added. Unfortunately, it was the one that x86 does not use, and this
+caused a lockdep splat on one of my tests. It only affected the -rt patch
+when PREEMPT_RT_FULL was not set, so I did not spend much time looking to
+see what broke.
+
+Well, I finally spent a little time and found the cause, and this was
+a simple fix. Now my all my tests pass on the v3.2-rt kernel, even the
+one where I test CONFIG_PREEMPT_RT_FULL not set.

+Subject: [PATCH 346/371] gpio: omap: use raw locks for locking
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=afe7db421552bde83c469e707aa093760ed4e7c9
+
+This patch converts gpio_bank.lock from a spin_lock into a
+raw_spin_lock. The call path is to access this lock is always under a
+raw_spin_lock, for instance
+- __setup_irq() holds &desc->lock with irq off
+  + __irq_set_trigger()
+   + omap_gpio_irq_type()
+
+- handle_level_irq() (runs with irqs off therefore raw locks)
+  + mask_ack_irq()
+   + omap_gpio_mask_irq()
+
+This fixes the obvious backtrace on -RT. However the locking vs context
+is not and this is not limited to -RT:
+- omap_gpio_irq_type() is called with IRQ off and has an conditional
+  call to pm_runtime_get_sync() which may sleep. Either it may happen or
+  it may not happen but pm_runtime_get_sync() should not be called with
+  irqs off.
+
+- omap_gpio_debounce() is holding the lock with IRQs off.
+  + omap2_set_gpio_debounce()
+   + clk_prepare_enable()
+    + clk_prepare() this one might sleep.
+  The number of users of gpiod_set_debounce() / gpio_set_debounce()
+  looks low but still this is not good.

+
+To ease backporting patches, replace the plist functions with
+rt_mutex_enqueue{_pi}() and rt_mutex_dequeue{_pi}() like upstream -rt does.
+This will lower the conflicts in backporting patches.
+
+This also makes sure that every time a waiter is added to the pi_list it
+matches the priority of the waiter list.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=fde36aeb56aa185c23c33eba82b3e804f952378c
+
+upstream-commit: 88f2b4c15e561bb5c28709d666364f273bf54b98
+
+Oleg noticed that rtmutex_slowtrylock() has a pointless check for
+rt_mutex_owner(lock) != current.
+
+To avoid calling try_to_take_rtmutex() we really want to check whether
+the lock has an owner at all or whether the trylock failed because the
+owner is NULL, but the RT_MUTEX_HAS_WAITERS bit is set. This covers
+the lock is owned by caller situation as well.
+
+We can actually do this check lockless. trylock is taking a chance
+whether we take lock->wait_lock to do the check or not.
+
+Add comments to the function while at it.

+
+The current implementation of try_to_take_rtmutex() is correct, but
+requires more than a single brain twist to understand the clever
+encoded conditionals.
+
+Untangle it and document the cases proper.
+
+Looks less efficient at the first glance, but actually reduces the
+binary code size on x8664 by 80 bytes.

+Subject: [PATCH 355/371] rtmutex: Cleanup deadlock detector debug logic
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=70ac96ae9c5ade7edfe2e9efc5bc65d1d13f4480
+
+upstream commit: 8930ed80f970a90a795239e7415c9b0e6f964649
+
+The conditions under which deadlock detection is conducted are unclear
+and undocumented.
+
+Add constants instead of using 0/1 and provide a selection function
+which hides the additional debug dependency from the calling code.
+
+Add comments where needed.

+ detection chain walk
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=9dc8944c0d56d8e3e14274abd5b079ca1c532d7d
+
+upstream commit: 67792e2cabadbadd1a93f6790fa7bcbd47eca7c3
+
+In case the dead lock detector is enabled we follow the lock chain to
+the end in rt_mutex_adjust_prio_chain, even if we could stop earlier
+due to the priority/waiter constellation.
+
+But once we are no longer the top priority waiter in a certain step
+or the task holding the lock has already the same priority then there
+is no point in dequeing and enqueing along the lock chain as there is
+no change at all.
+
+So stop the queueing at this point.

+Subject: [PATCH 357/371] futex: Make unlock_pi more robust
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=dbb203fd39083fcdbb45115034a8f70895e01167
+
+upstream commit: ccf9e6a80d9e1b9df69c98e6b9745cf49869ee15
+
+The kernel tries to atomically unlock the futex without checking
+whether there is kernel state associated to the futex.
+
+So if user space manipulated the user space value, this will leave
+kernel internal state around associated to the owner task.
+
+For robustness sake, lookup first whether there are waiters on the
+futex. If there are waiters, wake the top priority waiter with all the
+proper sanity checks applied.
+
+If there are no waiters, do the atomic release. We do not have to
+preserve the waiters bit in this case, because a potentially incoming
+waiter is blocked on the hb->lock and will acquire the futex
+atomically. We neither have to preserve the owner died bit. The caller
+is the owner and it was supposed to cleanup the mess.

+We want to be a bit more clever in futex_lock_pi_atomic() and separate
+the possible states. Split out the code which attaches the first
+waiter to the owner into a separate function. No functional change.

+ more robust
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=22762506782c21a3aedaee709d9fd51e4ffc80ca
+
+upstream commit: af54d6a1c3ad474bbc9893c9905022646be6092c
+
+futex_lock_pi_atomic() is a maze of retry hoops and loops.
+
+Reduce it to simple and understandable states:
+
+First step is to lookup existing waiters (state) in the kernel.
+
+If there is an existing waiter, validate it and attach to it.
+
+If there is no existing waiter, check the user space value
+
+If the TID encoded in the user space value is 0, take over the futex
+preserving the owner died bit.
+
+If the TID encoded in the user space value is != 0, lookup the owner
+task, validate it and attach to it.
+
+Reduces text size by 128 bytes on x8664.

+ deadlock
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=4e671f7086c89c73b73c990b33b1eb4f9d547243
+
+With task_blocks_on_rt_mutex() returning early -EDEADLK we never add the
+waiter to the waitqueue. Later, we try to remove it via remove_waiter()
+and go boom in rt_mutex_top_waiter() because rb_entry() gives a NULL
+pointer.
+Tested on v3.18-RT where rtmutex is used for regular mutex and I tried
+to get one twice in a row.
+
+Not sure when this started but I guess 397335f00 ("rtmutex: Fix deadlock
+detector for real") or commit 3d5c9340 ("rtmutex: Handle deadlock
+detection smarter").

+
+Oxc0000000 belongs to kernel address space, user task can not be
+allowed to access it. For above condition, correct result is that
+test case should receive a “segment fault” and exits but not stacks.
+
+the root cause is commit 02fe2845d6a8 ("avoid enabling interrupts in
+prefetch/data abort handlers"),it deletes irq enable block in Data
+abort assemble code and move them into page/breakpiont/alignment fault
+handlers instead. But author does not enable irq in translation/section
+permission fault handlers. ARM disables irq when it enters exception/
+interrupt mode, if kernel doesn't enable irq, it would be still disabled
+during translation/section permission fault.
+
+We see the above splat because do_force_sig_info is still called with
+IRQs off, and that code eventually does a:
+
+        spin_lock_irqsave(&t->sighand->siglock, flags);
+
+As this is architecture independent code, and we've not seen any other
+need for other arch to have the siglock converted to raw lock, we can
+conclude that we should enable irq for ARM translation/section
+permission exception.

+Subject: [PATCH 365/371] arm/futex: disable preemption during
+ futex_atomic_cmpxchg_inatomic()
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=fcaeac4a412858ad15c6746ac227a65a1306e961
+
+The ARM UP implementation of futex_atomic_cmpxchg_inatomic() assumes that
+pagefault_disable() inherits a preempt disabled section. This assumtion
+is true for mainline but -RT reverts this and allows preemption in
+pagefault disabled regions.
+The code sequence of futex_atomic_cmpxchg_inatomic():
+
+|   x = *futex;
+|   if (x == oldval)
+|           *futex = newval;
+
+The problem occurs if the code is preempted after reading the futex value or
+after comparing it with x. While preempted, the futex owner has to be
+scheduled which then releases the lock (in userland because it has no waiter
+yet). Once the code is back on the CPU, it overwrites the futex value
+with with the old PID and the waiter bit set.
+
+The workaround is to explicit disable code preemption to avoid the
+described race window.

+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2b1994d429a12b38764caef4de70340f95aab2bd
+
+"lockdep: Selftest: Only do hardirq context test for raw spinlock"
+disabled the execution of certain tests with PREEMPT_RT_FULL, but did
+not prevent the tests from still being defined.  This leads to warnings
+like:
+
+  ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_12' defined but not used [-Wunused-function]
+  ./linux/lib/locking-selftest.c:574:1: warning: 'irqsafe1_hard_rlock_21' defined but not used [-Wunused-function]
+  ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_12' defined but not used [-Wunused-function]
+  ./linux/lib/locking-selftest.c:577:1: warning: 'irqsafe1_hard_wlock_21' defined but not used [-Wunused-function]
+  ./linux/lib/locking-selftest.c:580:1: warning: 'irqsafe1_soft_spin_12' defined but not used [-Wunused-function]
+  ...
+
+Fixed by wrapping the test definitions in #ifndef CONFIG_PREEMPT_RT_FULL
+conditionals.

+Subject: [PATCH 370/371] fs,btrfs: fix rt deadlock on extent_buffer->lock
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=2f98c53099e350ce12e6777231b29c3d9ef7c34d
+
+Sat Jul 14 12:30:41 CEST 2012
+
+Trivially repeatable deadlock is cured by enabling lockdep code in
+btrfs_clear_path_blocking() as suggested by Chris Mason.  He also
+suggested restricting blocking reader count to one, and not allowing
+a spinning reader while blocking reader exists.  This has proven to
+be unnecessary, the strict lock order enforcement is enough.. or
+rather that's my box's opinion after long hours of hard pounding.
+
+Note: extent-tree.c bit is additional recommendation from Chris
+      Mason, split into a separate patch after discussion.
