hrtimer.h: prevent pinned timer state from breaking inactive test
An hrtimer may be pinned to a CPU but inactive, so it is no longer valid to test the hrtimer.state struct member as having no bits set when inactive. Changed the test function to mask out the HRTIMER_STATE_PINNED bit when checking for inactive state. Change-Id: Icb4156f4b7cb10138ea6c5cd5b762e35dc25428d Signed-off-by: Gary S.

hrtimer: create hrtimer_quiesce_cpu() to isolate CPU from hrtimers
To isolate CPUs (isolate from hrtimers) from sysfs using cpusets, we need some support from the hrtimer core. i.e. A routine hrtimer_quiesce_cpu() which would migrate away all the unpinned hrtimers, but shouldn't touch the pinned ones.

hrtimer: update timer->state with 'pinned' information
'Pinned' information would be required in migrate_hrtimers() now, as we can migrate non-pinned timers away without a hotplug (i.e. with cpuset.quiesce). And so we may need to identify pinned timers now, as we can't migrate them. This patch reuses the timer->state variable for setting this flag as there were enough number of free bits available in this variable. And there is no point increasing size of this struct by adding another field.

qos: Register irq notify after adding the qos request
Before adding the irq affinity based qos request to the list, if the affinity of the interrupt changes it will trigger notify call. This notifier call will try to update the qos request. Accessing the qos request which is not yet added to the list leads to a NULL pointer exception. Avoid this race by registering the notifier after adding the qos request.

tracing/fgraph: Fix set_graph_function from showing interrupts
commit 5cf99a0f3161bc3ae2391269d134d6bf7e26f00e upstream. The tracefs file set_graph_function is used to only function graph functions that are listed in that file (or all functions if the file is empty). The way this is implemented is that the function graph tracer looks at every function, and if the current depth is zero and the function matches something in the file then it will trace that function. When other functions are called, the depth will be greater than zero (because the original function will be at depth zero), and all functions will be traced where the depth is greater than zero. The issue is that when a function is first entered, and the handler that checks this logic is called, the depth is set to zero. If an interrupt comes in and a function in the interrupt handler is traced, its depth will be greater than zero and it will automatically be traced, even if the original function was not. But because the logic only looks at depth it may trace interrupts when it should not be. The recent design change of the function graph tracer to fix other bugs caused the depth to be zero while the function graph callback handler is being called for a longer time, widening the race of this happening. This bug was actually there for a longer time, but because the race window was so small it seldom happened. The Fixes tag below is for the commit that widen the race window, because that commit belongs to a series that will also help fix the original bug.

perf: Cancel the mux hrtimer during CPU hotplug to avoid migration
The current design of hrtimers migrates the pinned timers to a different CPU upon its hotplug. However, perf-core needs to maintain the mux-hrtimers on a per CPU basis. That is, each hrtimer carries the context for that particular CPU and would lose this context if it gets migrated to a different CPU. As a result, cancel the hrtimer for the CPU that's about to go down and restart it (if required) when the perf-events are being created.

perf: Fix event creation for task context
During the perf event creation, the perf-core ignores immediate installation of the events whose cpu is offline. However, this is only valid for events created in cpu context, but not for task context. The fix basically moves the check only for the events meant to be installed in cpu context.

perf: add hotplug support
The change is a squash of the following four commits taken
from msm-4.14:
1) commit <b02d7648fbd1> ("enable perf to continue across
hotplug")
Currently perf hardware, software and tracepoint events are
deleted when a cpu is hotplugged out. This change restarts
the events after hotplug. In arm_pmu.c most of the code
for handline power collapse is reused for hotplug.
This change supercedes commit 1f0f95c5fe9e ("perf: add hotplug
support so that perf continues after hotplug") and uses the
new hotplug notification method.
2) commit <9768e7af40d6> ("disable perf_event_read during hotplug")
core.c should not allow perf_event_read access during hotplug.
DCVS may try to read events during hotplug startup or
shutdown. Set a flag to not allow access during hotplug.
3) commit <1fc690b7b8c6> ("perf: core: Avoid race condition when
releasing perf-events")
Before calling perf_event_release_kernel(), capture
the perf's pmus_mutex lock to prevent the CPU from going offline
during the operation.
4) commit <77257e46efea> ("perf: Manage CPU hotplug events at
core level")
the approach here is to achieve the hotplug management
at the perf-core level. The idea is to detach the event from the
context (perf_remove_from_context()), when the CPU is about to come
down and re-attach it back (perf_install_in_context()), when the CPU
comes back online. The approach involves removing the logic for
maintaining zombie events (PERF_EVENT_STATE_ZOMBIE) and let the
dormant list itself carry the events whose CPUs are offline.

Perf: core: create/delete shared kernel/user events
This is a squash of the following two commits taken from msm-4.14
1) commit <e629221afd65> ("Perf: core: create/delete shared
kernel events").
Frequently drivers want to monitor some event like L2 misses
and cycles+instructions. If more than 1 driver wants to monitor
the same event and the event attributes are the same then we
can create just one instance of the event and let drivers
share the event. Add shared event create and delete
routines.
2) commit <f0453c73e167> ("perf: Add support for user and
kernel event sharing").
The ARM PMU counters are limited in number. Even for counting
similar events, the PMU driver allocates a new counter. Hence,
counters configured to count similar events are shared. This
was only possible for the kernel clients, but not for user-space
clients. Hence, as an extension to this, the kernel and the
user-space are now able to share the similar events. The counters
can be shared between user-space only clients, kernel only clients,
and among user-space and kernel clients. The kernel and user's
attr->type (hardware/raw) and attr->config should be same for them to
share the same counter.

cpu-hotplug: Always use real time scheduling when hotplugging a CPU
CPU hotplug operations take place in preemptible context. This leaves the hotplugging thread at the mercy of overall system load and CPU availability. If the hotplugging thread does not get an opportunity to execute after it has already begun a hotplug operation, CPUs can end up being stuck in a quasi online state. In the worst case a CPU can be stuck in a state where the migration thread is parked while another task is executing and changing affinity in a loop. This combination can result in unbounded execution time for the running task until the hotplugging thread gets the chance to run to complete the hotplug operation. Fix the said problem by ensuring that hotplug can only occur from threads belonging to the RT sched class. This allows the hotplugging thread priority on the CPU no matter what the system load or the number of available CPUs are. If a SCHED_NORMAL task attempts to hotplug a CPU, we temporarily elevate it's scheduling policy to RT. Furthermore, we disallow hotplugging operations to begin if the calling task belongs to the idle and deadline classes or those that use the SCHED_BATCH policy.

function_graph: Reverse the order of pushing the ret_stack and the callback
commit 7c6ea35ef50810aa12ab26f21cb858d980881576 upstream.
The function graph profiler uses the ret_stack to store the "subtime" and
reuse it by nested functions and also on the return. But the current logic
has the profiler callback called before the ret_stack is updated, and it is
just modifying the ret_stack that will later be allocated (it's just lucky
that the "subtime" is not touched when it is allocated).
This could also cause a crash if we are at the end of the ret_stack when
this happens.
By reversing the order of the allocating the ret_stack and then calling the
callbacks attached to a function being traced, the ret_stack entry is no
longer used before it is allocated.

function_graph: Move return callback before update of curr_ret_stack
commit 552701dd0fa7c3d448142e87210590ba424694a0 upstream.
In the past, curr_ret_stack had two functions. One was to denote the depth
of the call graph, the other is to keep track of where on the ret_stack the
data is used. Although they may be slightly related, there are two cases
where they need to be used differently.
The one case is that it keeps the ret_stack data from being corrupted by an
interrupt coming in and overwriting the data still in use. The other is just
to know where the depth of the stack currently is.
The function profiler uses the ret_stack to save a "subtime" variable that
is part of the data on the ret_stack. If curr_ret_stack is modified too
early, then this variable can be corrupted.
The "max_depth" option, when set to 1, will record the first functions going
into the kernel. To see all top functions (when dealing with timings), the
depth variable needs to be lowered before calling the return hook. But by
lowering the curr_ret_stack, it makes the data on the ret_stack still being
used by the return hook susceptible to being overwritten.
Now that there's two variables to handle both cases (curr_ret_depth), we can
move them to the locations where they can handle both cases.

function_graph: Have profiler use curr_ret_stack and not depth
commit b1b35f2e218a5b57d03bbc3b0667d5064570dc60 upstream.
The profiler uses trace->depth to find its entry on the ret_stack, but the
depth may not match the actual location of where its entry is (if an
interrupt were to preempt the processing of the profiler for another
function, the depth and the curr_ret_stack will be different).
Have it use the curr_ret_stack as the index to find its ret_stack entry
instead of using the depth variable, as that is no longer guaranteed to be
the same.

function_graph: Use new curr_ret_depth to manage depth instead of curr_ret_stack
commit 39eb456dacb543de90d3bc6a8e0ac5cf51ac475e upstream. Currently, the depth of the ret_stack is determined by curr_ret_stack index. The issue is that there's a race between setting of the curr_ret_stack and calling of the callback attached to the return of the function. Commit |

function_graph: Make ftrace_push_return_trace() static
commit d125f3f866df88da5a85df00291f88f0baa89f7c upstream.
As all architectures now call function_graph_enter() to do the entry work,
no architecture should ever call ftrace_push_return_trace(). Make it static.

function_graph: Create function_graph_enter() to consolidate architecture code
commit 8114865ff82e200b383e46821c25cb0625b842b5 upstream.
Currently all the architectures do basically the same thing in preparing the
function graph tracer on entry to a function. This code can be pulled into a
generic location and then this will allow the function graph tracer to be
fixed, as well as extended.
Create a new function graph helper function_graph_enter() that will call the
hook function (ftrace_graph_entry) and the shadow stack operation
(ftrace_push_return_trace), and remove the need of the architecture code to
manage the shadow stack.
This is needed to prepare for a fix of a design bug on how the curr_ret_stack

x86/speculation: Rework SMT state change
commit a74cfffb03b73d41e08f84c2e5c87dec0ce3db9f upstream arch_smt_update() is only called when the sysfs SMT control knob is changed. This means that when SMT is enabled in the sysfs control knob the system is considered to have SMT active even if all siblings are offline. To allow finegrained control of the speculation mitigations, the actual SMT state is more interesting than the fact that siblings could be enabled. Rework the code, so arch_smt_update() is invoked from each individual CPU hotplug function, and simplify the update function while at it.

However there is demand to also disable the key when the topology changes such that there is no SMT present anymore. Implement this by making the key count the number of cores that have SMT enabled. In particular, the SMT topology bits are set before interrrupts are enabled and similarly, are cleared after interrupts are disabled for the last time and the CPU dies.

x86/speculation: Apply IBPB more strictly to avoid cross-process data leak
commit dbfe2953f63c640463c630746cd5d9de8b2f63ae upstream
Currently, IBPB is only issued in cases when switching into a non-dumpable
process, the rationale being to protect such 'important and security
sensitive' processess (such as GPG) from data leaking into a different
userspace process via spectre v2.
This is however completely insufficient to provide proper userspace-to-userpace
spectrev2 protection, as any process can poison branch buffers before being
scheduled out, and the newly scheduled process immediately becomes spectrev2
victim.
In order to minimize the performance impact (for usecases that do require
spectrev2 protection), issue the barrier only in cases when switching between
processess where the victim can't be ptraced by the potential attacker (as in
such cases, the attacker doesn't have to bother with branch buffers at all).

x86/speculation: Enable cross-hyperthread spectre v2 STIBP mitigation
commit 53c613fe6349994f023245519265999eed75957f upstream STIBP is a feature provided by certain Intel ucodes / CPUs. This feature (once enabled) prevents cross-hyperthread control of decisions made by indirect branch predictors. Enable this feature if - the CPU is vulnerable to spectre v2 - the CPU supports SMT and has SMT siblings online - spectre_v2 mitigation autoselection is enabled (default) After some previous discussion, this leaves STIBP on all the time, as wrmsr on crossing kernel boundary is a no-no. This could perhaps later be a bit more optimized (like disabling it in NOHZ, experiment with disabling it in idle, etc) if needed. Note that the synchronization of the mask manipulation via newly added spec_ctrl_mutex is currently not strictly needed, as the only updater is already being serialized by cpu_add_remove_lock, but let's make this a little bit more future-proof.

ANDROID: add extra free kbytes tunable
Add a userspace visible knob to tell the VM to keep an extra amount of memory free, by increasing the gap between each zone's min and low watermarks. This is useful for realtime applications that call system calls and have a bound on the number of allocations that happen in any short time period. In this application, extra_free_kbytes would be left at an amount equal to or larger than than the maximum number of allocations that happen in any burst. It may also be useful to reduce the memory use of virtual machines (temporarily?), in a way that does not cause memory fragmentation like ballooning does. [ccross] Revived for use on old kernels where no other solution exists. The tunable will be removed on kernels that do better at avoiding direct reclaim.
