ASAN reports use-after-free in hwmontempsensor #20

Closed zevweiss closed 2 years ago

zevweiss commented 2 years ago

I'm working on some patches to allow dbus-sensors daemons to manage driver binding/unbinding on host power state transitions, which involves an increase in the amount of sensor object creation & destruction at runtime (post initialization), and started seeing some ASAN reports that didn't seem to be coming from my local changes; after some investigation I think there's a latent bug in the existing upstream code that just requires a bit more activity to trigger.

I reduced my local patch to the following, just enabling ASAN and adding a dbus method to trigger a createSensors() call:

(The LD_LIBRARY_PATH setting is just to allow it to find libasan.so.6, which I manually copied in after building the gcc-sanitizers package.)

zevweiss commented 2 years ago

On a suggestion from @edtanous I tried applying the following patch so that the readBuf destructor is ordered after the inputDev destructor:

diff --git a/include/HwmonTempSensor.hpp b/include/HwmonTempSensor.hpp
index 5cf77c384db0..8e478fca280a 100644
--- a/include/HwmonTempSensor.hpp
+++ b/include/HwmonTempSensor.hpp
@@ -36,9 +36,9 @@ class HwmonTempSensor :

   private:
     sdbusplus::asio::object_server& objServer;
+    boost::asio::streambuf readBuf;
     boost::asio::posix::stream_descriptor inputDev;
     boost::asio::deadline_timer waitTimer;
-    boost::asio::streambuf readBuf;
     std::string path;
     double offsetValue;
     double scaleValue;

I was still able to reproduce the problem, however (I believe this is functionally pretty much identical to the dump above, but I'll preserve it here in case there's a difference I've missed):

So:

  1. At line 422 we see handler 117 created for descriptor 0x73c0ea5c
  2. At line 432 we see descriptor 0x73c0ea5c closed
  3. At line 469 handler 117 is invoked

It looks like the documented behavior of boost::asio::posix::stream_descriptor::close() isn't actually happening, as far as I can see? (No ~ actions or handlers receiving boost::asio::error::operation_aborted in the asio trace.)

As an experiment I tried running with the following patch to re-do hwmontempsensor's read buffering as in this patch by @edtanous and have thus far been unable to reproduce the problem.

I would certainly like to understand what's going wrong with the existing buffering scheme (ASIO bug? some subtle misuse of its API?), but this might be a viable alternative that was probably likely to get done at some point in the not-too-distant future anyway.

IMO if we have a fix, and it has no downsides, we should just fix it on master, then chasing down the old bug becomes an academic exercise, which, we might want to do for learning on how to not find that issue again, but in the meantime, the core issue is fixed.

Get the above patch submitted to gerrit, and lets see if we can get it cleaned up and on master.

While the root cause remains mysterious, commit d1c8f44 appears to resolve this.
