[Qemu-devel] [RFC PATCH v2 0/7] QEMU binary instrumentation prototype

[Qemu-devel] [RFC PATCH v2 0/7] QEMU binary instrumentation prototype

[Pavel Dovgalyuk]

The following series implements dynamic binary instrumentation upon QEMU.

It is based on the following prior sources:
 - KVM Forum 2017 talk "Instrumenting, Introspection, and Debugging with QEMU"
   https://www.linux-kvm.org/images/3/3d/Introspect.pdf
 - Discussion on Lluis Vilanova instrumentation patch series
   https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg03357.html

There are many implementations of the instrumentation for QEMU.
We have our own attempt on github: https://github.com/ispras/qemu/tree/plugins
But this series differ from that approach and it is intended
to provide a stable interface for adding and extending the QEMU binary
analysis functions.

We propose adding new instrumentation API for QEMU which will include
the following parts:
 - some translator modifications to enable instrumenting the instructions
   (and memory operations in the next version of the patches)
 - dynamic binary instrumentation part (a sample which is currently submitted
   in this RFC series)
 - subsystem for dynamically loaded plugins that interact with this API

The aim of the instrumentation is implementing different runtime
tracers that can track the executed instructions, memory and
hardware operations. The implementation should not incur too much
overhead to make memory tracing as efficient as it is possible
for this heavy task.

The plugins should not have too many dependencies from the QEMU
core. They should be built as a separate projects using just
a couple of the headers.

For the current patches the plugins should provide the following
callbacks:
 - "needs" callback to check whether the specific instruction
   should be instrumented by this plugin
 - "run" callback which called before executing the instuction

Our instrumentation subsystem exploits TCG helper mechanism to embed
callbacks into the translation blocks. These callbacks may be inserted
before the specific instructions.

The aim of submission of this series at that early stage is to get
the feedback which will guide the development process. We are faced
the following questions:
 1. Does every plugins should have its own callback embedded into the TB
    (which will cause TB extra growth in case of multiple plugins),
    or the instrumentation layer's callback should invoke the plugins
    that wanted to instrument that specific instruction?
 2. How the plugins should function? Will they work as a binary dynamic
    libraries or a script on some interpreted language?
 3. Should the plugins reuse QEMU configuration script results?
    Now there is no possibility for using platform-specific macros
    generated by QEMU configure.
 4. Maybe QEMU module infrastructure should be extended to support
    plugins too?
 5. How the GDB-related CPU inspection interface may be used better?
    We should pass a register code to read the value. These codes
    are not described in any of the files. Maybe a function for
    accessing register by name should be added?


v2 changes:
 - added a subsystem for the plugins
 - added QEMU side API for plugins
 - added sample plugins for simple tracing

Could you use tostring() from include/qemu/compiler.h instead?

Thanks, fixed.

BTW, this was a copy-paste from helper-tcg.h

A small comment might be worthwhile here, maybe something like:

/**
 * tcg_register_helper
 *
 * Used by the helper-register.h machinery to register non-core helpers

[Qemu-devel] [RFC PATCH v2 2/7] Add plugin support

[Pavel Dovgalyuk]

This patch adds support for dynamically loaded plugins.
Every plugin is a dynamic library with a set of optional exported
functions that will be called from QEMU.

There are a couple of trivial conflicts vs master here, simple to fix.

It seems a bit heavyweight to have a query function here. Is this
dynamic state the plugin might change during execution? If not could we
not better report plugin requirements during initialisation?

In fact could the presence of an "optional" symbol imply it's need here?

Yes, it is dynamic.
For example, we created a plugin, which detects dynamic module loading
in the guest. Then it can add tracepoints to the entry addresses of the loaded
functions. These addresses are not known in advance.

I think you want to have an #ifdef CONFIG_PLUGINS here and some empty
inlines for the non CONFIG_PLUGINS case so you don't need to ifdef so
much later.

Thanks.
I'll better fix init, because all other invocations are command-line

Currently this is only available to system mode emulation. Can it be
extended to include linux-user as well?

Why not? I'm not familiar with linux-user, so I'll need some time to try.

[Qemu-devel] [RFC PATCH v2 3/7] plugins: provide helper functions for plugins

[Pavel Dovgalyuk]

From: Pavel Dovgalyuk <pavel.dovgaluk@ispras.ru>

This patch adds interface functions that may be called from the loaded plugins.
Such functions are needed to inspect the VM state and to pass data
to the QEMU (e.g., QEMU-side logging).

I don't really see the need for a plugin_need_foo call here. Can't we
just iterate over all plugins that provide a before_insn binding and
leave it at that?

If the plugin decides it doesn't want to do anything with this
particular instruction it can always bail early.

I wonder if we should have an explicit DEF_HELPER_FLAGS_2. Looking at
the flags though:

  /* call flags */
  /* Helper does not read globals (either directly or through an exception). It
     implies TCG_CALL_NO_WRITE_GLOBALS. */
  #define TCG_CALL_NO_READ_GLOBALS    0x0010
  /* Helper does not write globals */
  #define TCG_CALL_NO_WRITE_GLOBALS   0x0020
  /* Helper can be safely suppressed if the return value is not used. */
  #define TCG_CALL_NO_SIDE_EFFECTS    0x0040

  /* convenience version of most used call flags */
  #define TCG_CALL_NO_RWG         TCG_CALL_NO_READ_GLOBALS
  #define TCG_CALL_NO_WG          TCG_CALL_NO_WRITE_GLOBALS
  #define TCG_CALL_NO_SE          TCG_CALL_NO_SIDE_EFFECTS
  #define TCG_CALL_NO_RWG_SE      (TCG_CALL_NO_RWG | TCG_CALL_NO_SE)
  #define TCG_CALL_NO_WG_SE       (TCG_CALL_NO_WG | TCG_CALL_NO_SE)

I guess no flags means machine state is fully consistent before we make

OK I see what is happening here - but I worry about pushing off all
plugins into a single helper call with a fairly fixed amount of
information.

Would it be better to expose the generate helper API and maybe a few TCG
constants to the plugin function itself. It could then either emit
additional TCG operations or call to the helper - and deal with the
logic about if it should or shouldn't in a single call rather than doing
the need_foo call first.

Richard,

Will the TCG be smart enough to drop the pc/t_cpu variables if they are
ultimately not used by the instrument in this particular iteration?

The idea is to avoid TCG dependency.
We even can use an interpreter without changing the API of the plugins.
Therefore the helpers is the only way to do instrumentation.

I'm not sure it's worth having a null-template plugin if we can have one
or two well documented example plugins. It just runs the risk of
bitrot....

This isn't a good example. You can do this now with a much simpler:

  ${QEMU} -singlestep -d nochain,trace:exec_tb -D $trace ${BINARY}

Or even with a binary log:

  ${QEMU} -singlestep -d nochain -trace enable=exec_tb,file=$trace ${BINARY}

Which is all currently built-in. For the example to be worthwhile we
need to show how we can do something we currently can't do with the
existing infrastructure.

Perhaps a better example would be logging each PC execution to a hash
table so we can compute the hottest PC?

However that is going to require another API to allow information to be
exported from the plugin itself to report it's results.

I would have:

QEMU_SRC=../..
CFLAGS += -I$(QEMU_SRC)/include -fno-PIE -fPIC -O3

to make it clearer for out of tree plugins.

If the example plugins are going to sit in the main tree we should build
them (and ideally test they load/work during make check/tcg-check).

Again I'm not sure this is a very useful example either. It doesn't
achieve anything we can't already do with the existing logging/strace
stuff and it is quite ugly in it's knowledge of a single architecture to
try and figure out what's going on.

Not exactly. strace is intrusive, when running within the VM.
And this plugin does not affect the emulated system at all (except the slowdown).

Ahh in system emulation of course. However its still seems pretty ugly
given we start poking around in memory to figure out if we want to trap
in or around this particular x86 instruction.

It would be nice to have a generalised interface to say "I want to hook
before/after a certain pattern is decoded" but I guess this is tricky
given the translator is free to end any block after an instruction and
it doesn't know what is coming up before you enter translation. I guess
that would involve splitting .translate_insn into a decode and translate
step and that would be quite messy for the non-regular instruction
decoders like x86.

Maybe the API is always destined to be a messy one?

This series doesn't seem to add anything to Documentation/ that
describes the API we make available to plugins. I'm a lot more
interested in reviewing the API that will be used by plugins
than I am in the implementation at this stage. Can you provide
a description/documentation of the API for review, please?

Here is the draft:

Introduction
============

This document describes an API for creating the QEMU
instrumentation plugins.

It is based on the following prior sources:
 - KVM Forum 2017 talk "Instrumenting, Introspection, and Debugging with QEMU"
   https://www.linux-kvm.org/images/3/3d/Introspect.pdf
 - Discussion on Lluis Vilanova instrumentation patch series
   https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg03357.html

The aim of the instrumentation is implementing different runtime
tracers that can track the executed instructions, memory and
hardware operations.

Instrumenting the code
======================

Instrumentation subsystem exploits TCG helper mechanism to embed
callbacks into the translation blocks. These callbacks may be inserted
before the specific instructions, when the plugins require such filtering.

Translator uses two functions for embedding the callbacks:
 - first function checks whether the current instruction should be
   instrumented
 - second function embeds the callback for executing the plugin-specific
   code before that instruction

The similar method may be used for memory access instrumentation.

QEMU->Plugin API
================

Instrumentation layer passes the requests from the translator
to the dynamically loaded plugins. Every plugin may provide
the following functions to perform the instrumentation:

 1. bool plugin_init(const char *args);
    Initialization function. May return false if the plugin
    can't work in the current environment.

 2. bool plugin_needs_before_insn(uint64_t pc, void *cpu);
    Returns true if the plugin needs to instrument the current instruction.
    It may use the address (pc) for making the decision or the guest
    CPU state (cpu), which can be passed back to QEMU core API
    (e.g., for reading the guest memory).
    This function is called at both translation and execution phases.

 3. void plugin_before_insn(uint64_t pc, void *cpu);
    If the previous function returned true for some instruction,
    then this function will be called. This process is repeated before
    every execution of the instruction, if it was instrumented.

The similar pair of functions will also be added for the memory
operations.

Plugin->QEMU API
================

QEMU core exports some functions to let the plugins introspect the guest
or perform some interaction with other QEMU services (e.g., logging).
API doesn't contain any data structures, because their memory layout depend
on the compilation settings.

QEMU exports the following functions that may be called from the plugins:

 1. void qemulib_log(const char *fmt, ...);
    Wrapper for qemu_log.

 2. int qemulib_read_memory(void *cpu, uint64_t addr, uint8_t *buf, int len);
    Reads guest memory into the buffer. Wrapper for cpu_memory_rw_debug.

 3. int qemulib_read_register(void *cpu, uint8_t *mem_buf, int reg);
    Uses target gdb interface for accessing the guest registers.
    'reg' is the id of the desired register as it is coded by gdb.

There also should be a function for flushing the translated blocks to
ensure that the instrumentation will occur in the case of changing
the internal plugin state.

This would certainly be the case if we could generate TCG code in the plugins.

Please document how plugin loading and argument handling works.

Do you think unloading is necessary?  For example, on a long-running
guest it could be useful to unload the plugin, modify and recompile it,
and then load it again during development.  And maybe unloading is also
useful in cases where a plugin produces a lot of data or slows down
execution of a long-running guest.

What type of address is 'pc' - guest virtual or guest physical?

Is the guest CPU state well-defined when this function is called?  For
example, is reading CPU registers meaningful in this function since it
could be called at pretty much any time?

Why is this function called during execution?  I expected this to be
called at translation time only.  If a plugin decides at runtime to
instrument instructions that were previously not instrumented, then it
could flush the relevant TB(s) - that seems a lot more efficient than
calling this function for every instruction that gets executed.  But
maybe I am missing a use case for calling this at execution time...?

Plugins that instrument multiple kinds of instructions will have to
first look up pc and decide which kind of instruction it is.  The plugin
could keep a list or hash table, or it could read memory to check the
guest code again.  This will be very repetitive - many plugins will need
to do this.

A slightly different take on this API is:

  /* Plugin->QEMU API */

  /* Called by QEMU before translating an instruction
   * @pc: guest virtual address of instruction
   */
  void plugin_pre_translate(void *cpu, uint64_t pc);

  /* QEMU->Plugin API */

  /* A callback invoked by QEMU before executing an instrumented
   * instruction
   * @opaque: plugin-specific data
   */
  typedef void (*InstrumentCallback)(void *cpu, void *opaque);

  /* Register a callback @cb each time the instruction at @pc is about
   * to be executed
   * @cpu: the cpu to instrument or NULL to instrument all cpus
   * @opaque: plugin-specific data that is passed to @cb
   */
  void instrument(void *cpu, uint64_t pc,
                  InstrumentCallback cb,
                  void *opaque);

  /* Unregister a callback @cb previously registered using instrument()
   */
  void uninstrument(void *cpu, uint64_t pc,
                    InstrumentCallback cb,
		    void *opaque);

Here plugin_pre_translate() is similar to plugin_needs_before_insn(),
but note it has no return value.  Instead of telling QEMU whether or not
to instrument an instruction, it must call instrument() if it wishes to
receive a callback immediately before a particular instruction is
executed.

This is just an idea I wanted to share.  You understand the use cases
for binary instrumentation much better than me.  Feel free to disregard
if it doesn't fit.

Yes, I think we'll need it, but I omitted it in the draft.
Will fix in the next version.

It is a guest virtual address. We can expose a function for address translation
to let the plugin obtain physical address.

It is not. The guest state is the same as in translate.c.
Therefore such functions are limited in accessing the registers.

It isn't called for every executed instruction. It is called for instructions
that was marked by the same function to instrument.
I had a choice of two options:
 - insert many callbacks in case of multiple plugins, but call 'needs' only once.
 - insert one callback to dispatch function and call 'needs' for every plugin again,
   because there is no information which plugin caused the instrumentation.

Anyway, we can switch to the first option, if you don't see any other pitfalls
except the larger generated code.

This is interesting point I missed.
As far, as I understand, current version translates TB only once for all CPUs.
And we could need to instrument only some of them, which means that translation
should be somehow extended for that.

This is similar to our current approach here: https://github.com/ispras/qemu/tree/plugins

But it has some issues:
 - You can't switch QEMU core from translation to interpretation, because this interface
   is targeted to translation.
 - Callbacks can't be inserted without registering them in tcg
   (this in needed at least for debug output).
   Therefore someone should maintain already registered callbacks, or we should
   expose the registration interface to the plugins (as we do in our projects now),
   which also nail them to the translation-based emulation.

I think with a little re-jigging we could reduce this to a single run
call which can then decide if it is going to deal with things in this
case.

The common case is having one plugin and I'd rather give the flexibility
of what helper to call and how much information to give it to the plugin
and deal with the potential to have multiple helper calls per
instruction for the complex cases.

Now I can see arguments against it from an interface complexity point of
view but I think plugins should get access to the TCG functions so they
can generate their own op sequences if need be and not have to call a
helper at all if they don't need to.

I think plain C dynamic libraries with optional TCG ops would be a
sensible starting point. For the sort of analysis that potentially
involves lots of operations adding an interpreted language would be:

  - a bike-shedding operation (everyone has a favourite)
  - slower than C

It depends but I'm of the opinion that you build your plugins for the
QEMU you have and not expect them to run with any other version.
Defining some sort of cross-version API stability is just making a rod
for our own back.

Pass - I'm not very knowledgeable about what the existing module stuff
does.

Personally it feels a bit hacky at the moment. Perhaps we should be
looking at exposing tcg_global to the plugin interface. They are already
registered with names and it would be more efficient to load from TCG
code into the helper.

I strongly disagree -- plugins should not have access to details
of QEMU internals that might change from version to version, and
definitely not access to generating their own TCG code.

The problem is I think a simple single helper with a PC and a CPU env is
fairly inflexible and inefficient. It would also make the API simpler if
we could leave the decision about installing the helper to the
instrumentation function. However I take your point that exposing the
whole TCG API might be a bit too much. Perhaps the qmeulib functions
could wrap enough so we could have an instrumentation function like
this:

  void plugins_instrument_before_insn(target_ulong disas_pc)
  {
      TCGv t_pc = qemulib_make_const(pc);
      qemulib_call_helper1(pc);
  }

By marshalling through qemulib we could keep track of temps allocated
and do the clean-up for the plugin or take the approach that plugin
writers need to have some idea of what they are doing.

In terms of the wider problem about exposing internals that might change
from version to version I wonder if we should care? Is the plugin API
one where we should provide ABI stability or should we take the approach
that Linux does and say if your code lives out-of-tree then it's your
problem to keep up if/when we change.

Then one can just omit the plugins and embed the analysis code into QEMU.
The idea behind the plugins is making the maintenance less time-consuming
by providing the stable interface.
