[2.7] bpo-38106: Fix race in PyThread_release_lock that can lead to memory corruption and deadlock by navytux · Pull Request #16047 · python/cpython

navytux · 2019-09-12T13:24:04Z

On Darwin, even though this is considered as POSIX, Python uses
mutex+condition variable to implement its lock, and, as of 20190828, Py2.7
implementation, even though similar issue was fixed for Py3 in 2012, contains
synchronization bug: the condition is signalled after mutex unlock while the
correct protocol is to signal condition from under mutex:

https://github.com/python/cpython/blob/v2.7.16-127-g0229b56d8c0/Python/thread_pthread.h#L486-L506
187aa545165d (py3 fix)

PyPy has the same bug for both pypy2 and pypy3:

https://bitbucket.org/pypy/pypy/src/578667b3fef9/rpython/translator/c/src/thread_pthread.c#lines-443:465
https://bitbucket.org/pypy/pypy/src/5b42890d48c3/rpython/translator/c/src/thread_pthread.c#lines-443:465

Signalling condition outside of corresponding mutex is considered OK by
POSIX, but in Python context it can lead to at least memory corruption if we
consider the whole lifetime of python level lock. For example the following
logical scenario:

      T1                                          T2

  sema = Lock()
  sema.acquire()

                                              sema.release()

  sema.acquire()
  free(sema)

  ...

can translate to the next C-level calls:

      T1                                          T2

  # sema = Lock()
  sema = malloc(...)
  sema.locked = 0
  pthread_mutex_init(&sema.mut)
  pthread_cond_init (&sema.lock_released)

  # sema.acquire()
  pthread_mutex_lock(&sema.mut)
  # sees sema.locked == 0
  sema.locked = 1
  pthread_mutex_unlock(&sema.mut)

                                              # sema.release()
                                              pthread_mutex_lock(&sema.mut)
                                              sema.locked = 0
                                              pthread_mutex_unlock(&sema.mut)

                      # OS scheduler gets in and relinquishes control from T2
                      # to another process
                                              ...

  # second sema.acquire()
  pthread_mutex_lock(&sema.mut)
  # sees sema.locked == 0
  sema.locked = 1
  pthread_mutex_unlock(&sema.mut)

  # free(sema)
  pthread_mutex_destroy(&sema.mut)
  pthread_cond_destroy (&sema.lock_released)
  free(sema)

  # ...
  e.g. malloc() which returns memory where sema was

                                              ...
                      # OS scheduler returns control to T2
                      # sema.release() continues
                      #
                      # BUT sema was already freed and writing to anywhere
                      # inside sema block CORRUPTS MEMORY. In particular if
                      # _another_ python-level lock was allocated where sema
                      # block was, writing into the memory can have effect on
                      # further synchronization correctness and in particular
                      # lead to deadlock on lock that was next allocated.
                                              pthread_cond_signal(&sema.lock_released)

Note that T2.pthread_cond_signal(&sema.lock_released) CORRUPTS MEMORY as it
is called when sema memory was already freed and is potentially
reallocated for another object.

The fix is to move pthread_cond_signal to be done under corresponding mutex:

  # sema.release()
  pthread_mutex_lock(&sema.mut)
  sema.locked = 0
  pthread_cond_signal(&sema.lock_released)
  pthread_mutex_unlock(&sema.mut)

To do so this patch cherry-picks thread_pthread.h part of the following 3.2 commit:

commit 187aa545165d8d5eac222ecce29c8a77e0282dd4
Author: Kristján Valur Jónsson <[email protected]>

    Signal condition variables with the mutex held.  Destroy condition variables
    before their mutexes.

Bug history

The bug was there since 1994 - since at least [1]. It was discussed in 2001
with original code author[2], but the code was still considered to be
race-free. In 2010 the place where pthread_cond_signal should be - before or
after pthread_mutex_unlock - was discussed with the rationale to avoid
threads bouncing[3,4,5], and in 2012 pthread_cond_signal was moved to be
called from under mutex, but only for CPython3[6,7].

In 2019 the bug was (re-)discovered while testing Pygolang[8] on macOS with
CPython2 and PyPy2 and PyPy3.

I wrote a different description for the change:

Until now libgolang had semaphore and mutex functionality, but implemented only internally and not exposed to users. Since for its pinner thread wendelin.core v2 needs not only nogil channels, but also nogil mutexes, timers and so on, it is now time to start providing that. We start with mutexes: - Expose Mutex from insides of libgolang.cpp to public API in libgolang.h . We actually expose both Mutex and Sema because semaphores are sometimes also useful for low-level synchronization, and because it is easier to export Mutex and Sema both at the same time. - Provide pyx/nogil API to those as sync.Mutex and sync.Sema. - Provide corresponding python wrappers. - Add Pyx-level test for semaphore wakeup when wakeup is done not by the same thread which did the original acquire. This is the test that was promised in 5142460 (libgolang/thread: Add links to upstream PyThread_release_lock bug), and it used to corrupt memory and deadlock on macOS due to CPython & PyPy runtime bugs: https://bugs.python.org/issue38106 -> python/cpython#16047 https://bitbucket.org/pypy/pypy/issues/3072 Note about python wrappers: At present, due to cython/cython#3165, C-level panic is not properly translated into Py-level exception in (Py)Sema/Mutex constructors. This should not pose a real problem in practice though.

For the reference: a test for this issue is included in pygolang: https://lab.nexedi.com/kirr/pygolang/commit/34b7a1f4.

Background: in 2019 in 4dc1a7f0 (tox += ThreadSanitizer, AddressSanitizer, Python debug builds) I've added ThreadSanitizer and AddressSanitizer to our test build matrix. That was done in order to help catching concurrency issues while doing quality assurance and it indeed worked well(*). However AddressSanitizer was added with disabled memory leak detection, because at that time there were tons of various allocations done by Python itself, that were not released on Python shutdown. So leak reporting pass was disabled to avoid huge non-pygolang related printouts. 5 years later Pygolang is used by various projects, including in XLTE, where, in particular, it is used to organize 100Hz polling of Amarisoft eNodeB service to retrieve information about flows on Data Radio Bearers: https://lab.nexedi.com/kirr/xlte/-/commit/2a016d48 https://lab.nexedi.com/kirr/xlte/-/blob/8e606c64/amari/drb.py And everything works relatively well except that recently Joanne approached me with reports that xamari program, that does the polling, is leaking memory. During investigation I could manually find at least two causes of the leakage, and, while working on a fix, discovered third type of leak. Since all those leaks happen inside Pygolang and at, or around, C level - most of the time not visible through python objects and so not discoverable via e.g objgraph, it raises the need to have robust quality assurance procedures built into maintenance process to cover not only concurrency and memory safety issues, but also to reliably detect low-level memory leaks. So before we start fixing any of the leakages, let's activate LeakSanitizer (https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer) to be present during tox runs, so that whenever we run something via ASAN in the end tested process is checked for whether anything was leaked and if yes, which codepath was used to allocate leaked memory. Initially I though that it would be hard to have distilled reports, the ones without much of added noise due to leaks on python side, but it turns out that starting from py3.11 cpython codebase was improved to release on interpreter shutdown most of what was allocated, and so with modest suppression rules we can distill LeakSanitizer output to come with the issues that are relevant to pygolang itself. That builds the foundation for making sure there are no memory leaks done by pygolang in the follow-up patches. The next patch will fix chan leakage in pychan_from_raw, and there will be more fixes to come later. For now ASAN builds become broken, but that is good that we can see the issues. Please see the appendix for current LeakSanitizer output. /cc ORS team (@jhuge, @lu.xu, @tomo, @xavier_thompson, @Daetalus) /reviewed-by @jerome /reviewed-on https://lab.nexedi.com/nexedi/pygolang/-/merge_requests/24 (*) at that time, besides discovering longstanding race-condition in Python itself (https://bugs.python.org/issue38106, https://github.com/python/cpython/pull/16047), several concurrency issues were found in pygolang codebase as well: https://lab.nexedi.com/nexedi/pygolang/commit/dcf4ebd1 https://lab.nexedi.com/nexedi/pygolang/commit/65c43848 https://lab.nexedi.com/nexedi/pygolang/commit/5aa1e899 https://lab.nexedi.com/nexedi/pygolang/commit/fd2a6fab -------- Appendix.
