Re: [DynInst_API:] building dyninst with -fsanitize-address

[Xiaozhu Meng]

Hi Stan,

Most of the listed locations are creating boost::shared_ptr objects. Does 
address sanitizer work well with Boost library?

Thanks,

Fixes dyninst/dyninst#630

Other improvements include faster compile time (for affected files), ~1.2s less 
lazy init time, ~7.8MiB smaller binary, and ~10MiB less heap usage.

* Fixes for the more pedantic issues

* Splice out the operandFactory tables.

* Splice out the nodeBranches tables.

  Fixes for AbsRegion and jump table index slicing involving global variable 
(#695)

1. When converting AbsRegion, PC on x86/64 should use post-instruction address

2. During jump table index slicing, we should only read read-only memory 
locations.
   Note that we still allow reading writable memory locations during jump table 
reads
   as jump tables may be put in writable sections by compilers

  1. When converting AbsRegion, PC on x86/64 should use post-instruction address
2. During jump table index slicing, we should only read read-only memory 
locations.
   Note that we still allow reading writable memory locations during jump table 
reads
   as jump tables may be put in writable sections by compilers

  Parallel DWARF parsing and improved parallel code parsing (#651)

* changes for parallelizing symtabapi

* Tweaks to use OpenMP (still one last reducer left)

* Mark a false race in Type.C.
std::call_once has a barrier at the end, so anything that happens inside is 
visible to anything that happens after.

* Replace the Cilk reducer with an OpenMP reduction

* Remove some dead code, and move the reducer into the source file.

* Mark the last race so far, move VG macros to a separate file.

* Annotate the two core locks, negating a lot of the race reports
Implementation is not great though, I moved mcs_init to be a real function 
call.
There might be a better way to do this, will investigate at some point.

* Very awkwardly annotate a parallel hashmap by key. Consider implementing 
better magic.

* Wrap the callback in `omp critical`, to make it parallel-safe no matter what 
happens.

* Swap out the vector for a TBB concurrent_queue.

* Remove some unnessesary annotations, using a proper OpenMP handles them.

* Revert the core lock annotations, they don't actually really work.

* Macro-replace the locks with boost equivalents. Revert this commit later once 
the testing is complete, or refactor it fully out.

* Replace the 1-entry cache with a vector that expands with the number of 
threads.

* Reus

The ParseAPI of Dyninst implements a static analysis to resolve jump table 
targets, which works well on x86, Power and ARM. ParseAPI does not specifically 
provide an API for querying jump tables. However, you can iterate every 
function and every basic blocks to find whether a basic block ends with a jump 
table. 

By design, Dyninst does not need any instrumentation for resolving jump tables. 
If you find jump tables that are not properly resolved, you file a bug report 
on the Dyninst github webpage as an issue (https://github.com/dyninst/dyninst 
). 

If you are interested in using instrumentation (regardless of static 
instrumentation or dynamic instrumentation) for resolving indirect calls or 
indirect tail calls, you can use BPatch_dynamicTargetExpr() provided in the 
BPatch level interface. I don’t think you need to use PatchAPI for control flow 
related instrumentation.

The ParseAPI example contains the code needed to construct the CFG and iterate 
functions and basic blocks.

The following interface returns whether it is a non-returning function.

There are some ParseAPI example code here:

Re: [DynInst_API:] control flow enforcement

[Xiaozhu Meng]

Yes, Dyninst will need to adjust trampoline installation for Intel control flow 
enforcement, but the needed change should be quite straightforward: instead of 
always installing trampolines at function entry or block entry, we need to skip 
this special NOP-like instruction.

springboards, without involving software breakpoints.

Re: [DynInst_API:] ppcle detach removes snippets

[Xiaozhu Meng]

Stan reported this problem as issue 634 
(https://github.com/dyninst/dyninst/issues/634 
) yesterday. I am able to 
reproduce this problem and identify what caused the problem. 

The problem here is that during dynamic instrumentation by attaching to the 
mutatee process, instrumentation seems to be removed by calling 
BPatch_process::detach(), and this problem only shows up on power, not x8664 or 
ARM.

It turns out that in this case, a trap springboard is used to transfer program 
execution from original code to instrumentation. In dynamic instrumentation, 
all trap instructions generated by Dyninst are also considered as software 
break points by Dyninst, and Dyninst decides to remove all software break 
points when it detaches from the mutatee.

I am not sure how many and when software break points are used in Dyninst, but 
a springboard trap does not serve the purpose as a software break point and 
should not be removed during detaching. 

So, my plan is to simply generate a trap instruction when a trap springboard is 
needed, without registering this trap as a software break point.

Let me know if there are any concerns.

Thanks,

—Xiaozhu

Hi Stan,

I agree that detach should not remove instrumentation. 

Is it a power 8 or power 9 machine? And presumably it is Dyninst 10.1? Is it 
possible to set up a VM for me to debug this problem?

Before the VM is ready, there are a few quick things for you to try:

(1) "app_proc->detach(true);" actually will continue the mutatee, so you 
don’t have to call "app_proc->continueExecution();” before it. I know that this 
combination works on other platforms, but I just want to isolate the problem. 
Can you see if the same problem occurs if you delete “continueExecution()”?

(2)  detach will remove instrumentations in fork, exec, and exit, which are 
used for controlling the mutatee. Can you go to source file 
dyninstAPI/src/dynProcess.C and comment out lines between 1064 and 1069? These 
lines should look like:


tracedSyscalls_->removePreFork();
tracedSyscalls_->removePostFork();
tracedSyscalls_->removePreExec();
tracedSyscalls_->removePostExec();
tracedSyscalls_->removePreExit();
tracedSyscalls_->removePreLwpExit();

If commenting out these lines makes the instrumentation stay, then it means 
there is some side-effect when removing instrumentation for fork, exec, and 
exit. Again, this is just for diagnosis, but a real attempt to fix anything.

Thanks,

—Xiaozhu

I see. Thanks!

Can you tell us the specific intel compiler version, and your specific
command for building Dyninst and the example? We will try to reproduce your
problem.

Re: [DynInst_API:] Segmentation fault error with dyninst 10.1

[Xiaozhu Meng]

Hi,

It looks like that you compiled the example with the intel compiler. Do you
compile Dyninst with the same intel compiler? Different compilers may
generate ABI incompatible libraries and executable.

Thanks,

--Xiaozhu

Do you really mean you get a segfault when you compile the example?

If you encountered a segfault when you "run" the executable, can you use
GDB to collect a stack trace?

  Fix DwarfFrameParser, decodeDwarfExpression and DwarfResult

After porting Dyninst to use libdw, DwarfFrameParser missed dealing
with important Dwarf operations that would decode rules for findind
registers values. These rules were not properly decoded by Dyninst
decodeDwarfExpression, neither were being dealt by DwarFrameParser.
This fix properly retrieves libdw Dwarf operations and decodes them,
making it possible to DebugStepper work, which wasn't even before the
port, when lidwarf was being used on Dyninst 9.3.

Basically, Dwarf frame info can be a simple dwarf expression, representing
a value or a memory address, a location description, or a location list.
Libdw gives the consumer an array of dwarf operations that describes how
to find the value they're looking for, as opposed to libdwarf who gives
the consumer many out parameters that lead to different ways to find a
value. This important change made DwarfFrameParser work only partially
after the port. And this fix came to implement the cases that were not
being considered.

  1. If ParseAPI identifies a jump as a tail call, but later find that this 
jump is the only incoming edge of the targXXX function, we should not treat 
this jump as a tail call.

In theory, it is reasonable either way. However, treating such jump
as a tail call can cause troubles for function entry instrumentation.
If the targXXX function may jump back to the original function, and
thus reach the tail jump. This becomes a recursive tail call.

However, Dyninst relocation seems to have problem adjusting the tail jump
to include entry instrumentation.

2. If the determination of a tail call is changed, we should re-compute
function boundaries, including ret blocks, exit blocks, call edges

  Correctness fixes for springboard generators

This patch deals with issues where incorrect springboards could be generated.
Specifically addresses three issues:

1. Springboards trampling function data (addresses github issue #551)

2. Required springboards being spilling over block bounds onto
   other required springboards. Prior a if two required springboards were
   located near each other, there was a chance that one of the springboards
   could be partially overwritten resulting in broken behavior.

3. Unsafe reusage of a codegen object where if a trap was needed,
   both a branch and a trap would be written causing bad behavior.

  BPatch_effectiveAddress truncates mem addresses on Power (#593)

In certain circumstances, BPatch_effectiveAddress would generate code that 
truncated
memory addresses to the bottom 32bits. The result is that instrimentation would 
see only
the bottom 32bits of any memory address. Before this patch, the issue occurred 
when instrumentation was applied to load/store instructions where the address 
was located in registers r3-r11 (exclusive). Ideally this function should just 
be straight removed in future releases (only used by emitASLoad).

We fall back to use ptrace if procfs read & write fail.

This change is for fixing icache coherence issue for ARM dynamic 
instrumentaiton.
ARM architecture does not guarantee icache-dcache coherence. And writes through
ptrace does not seem to invalidate icache contents and caused SIGILLs

  Add --enable-install-elfh when building elfutils from source (#555)

When building elfutils from source on systems that have old elfutils,
Dyninst couldn't find the correct version of elf.h due to it not
being copied from the elfutils build source directory to the include
directory. In the Feb 15 2019 release of elfutils, this flag was
added to fix this.

  Fix tests in PIC mode (#553)

* In dynamic instrumentation for PIE, finding variables's locations needs to 
add the load base of the PIE.
Get rid of wrong, special handling of finding the load base of PIE.
* On x86-64, when emulating call with push & jmp, the push needs to push all 
64-bit of the callee addresses.
* A few fixes for PIC instrumentation on power
1. Fix PC-relative load and store of variables
2. The preamble of PIE uses R12 to set up R2. However,
when generating intra-module calls, Dyninst does not
set up R12 and will call the global entry, causing R2 to
be incorrect. Since there is no need to change R2 for
intra-module calls, we should call the local entry
* Fix function call replacment on power for PIC.
Need to call local entry when doing an intra-module call
* Handle relocation type R_X86_64_REX_GOTPCRELX for binary rewriting of 
statically linked binaries on x86-64

  Attempts to fix legacy test failures in Dyninst test suite (#549)

* In binary rewriting, when Dyninst needs to load a library,
it does not check whether this library has been loaded before or not.
Dyninst will create multiple binaryEdit objects for one library, which can 
cause inconsistent states between these objects.

This fix adds a map to BPatch_binaryEdit to make sure each library is only 
loaded once.

* Fix pc_tls failures in dyamically linked binaries.
The root cause is a broken library name matching code.
Just should boost:filesystem::path to deal with file paths.

Closes #549

  Fix unnecessary multiple calls to buildSysRegMap.

This function should be called only once, but was being called for every
instruction to be decoded. As a result, dyninst would take a long time
to execute. Now to simply run test1_1 on create mode takes 28 seconds,
as opposed to 58 before this fix, and now closer to 20 seconds for x86_64.

  Log Message:
  ---
  For jump table analysis, control flow edges can be created in different 
orders,
which lead to non-deterministic slicing and non-determinisitc jump table 
analysis.

Therefore, we need to sort source edges in slicing based on the edge's source 
block
address and edge type to ensure deterministic slicing.

Re: [DynInst_API:] Basic Block reordering / modification using DynInst

[Xiaozhu Meng]

Hi Sameer,

Dyninst does not have a public interface for reordering basic blocks
within a function, even though it is capable of doing so. Basic block
level instrumentation is supported.

Thanks,

--Xiaozhu

  1. Replace springboards prioriy "OffLimits" and "Required" with "FuncEntry" 
and "IndirBlockEntry".

Only "FuncEntry" springboards are required because control flow enter 
instrumentation
through function calls (we relocate the whole function even if only a part of 
the
function is instrumented).

"IndirBlockEntry" springboards are important for re-directing control flow from
jump tables back to instrumentation. But, it is not as important as "FuncEntry".

2. Jumps to code in another secion should be treated as tail calls.
