[Bug c++/29496] New: _M_invalidate function is not thread-safe in GLIBCXX_DEBUG mode

[Bug c++/29496] New: _M_invalidate function is not thread-safe in GLIBCXX_DEBUG mode

[l_heldt at poczta dot onet dot pl]

_M_invalidate function in safe_iterator.tcc is not thread safe against
_M_detach()/_M_attach() functions from _Safe_iterator_base.

Here is the example of erronous scenario:

Thread1()
{
   list::iterator iter;
   lock(mutex);
   iter = myList.begin();
   ....
   // do something with iter
   ....
   unlock();  
}

Thread2()
{
   lock(mutex);
   myList.erase(myList.begin());
   unlock();  
}

The problem in this scenario is that while calling erase(), _M_invalidate()
function is called which goes through the list of all iterators without taking
a lock on __gnu_internal::iterator_base_mutex. At the same time another thread
can be deallocating lists iterator - thus calling _M_detach() function.
This leads to a SIGSEGV in _M_invalidate() function.

You should either remove concurrency support from GLIBCXX_DEBUG mode or provide
full support.

Let's suppose the issue is confirmed, and we have an useful complete testcase,
then, a wild idea (at the moment I'm missing many details about the internals
of the safe iterators, sorry): maybe we could explore the possibility to have
the _M_invalidate functionality part of _Safe_iterator_base, thus easily use
the debug mode mutex. I'm saying that because I'm under the impression that
_M_invalidate basically uses info available in the _Safe_iterator_base. I'm
only unsure about the tests "this->base() == __victim->base()", I hope can be
done on the base objects too...

And of course it can't, such simply, the plain iterator info is necessary here,
because we want to change *all* iterators pointing the same as this->base()...
In case, looks like _M_invalidate needs a more complex interaction between
_Safe_iterator and _Safe_iterator_base...

I encountered this bug (?) in the past. I thought, maybe incorrectly, that
accessing an interator (e.g copying it) equals read access to a container,
hence no thread safety guarnatees for concurrent modifications to the container
- like erase on another element.

OTOH, this works fine in non-debug mode.

Paolo: Seems like an interesting idea.

Grzegorz: interesting that others have run into this. Without a testcase, it's
hard to say with certainty what is valid and what is invalid. Also, without a
testcase there are no certainties that if fixed, it remains fixed. Thus, why
I'm insisting on a testcase. Care to give it a go?

This bug is a pure race-condition. There is no test case which would reveal it
with a 100% certainty. I have noticed the bug after receiving strange SIGSEGV
in _M_invalidate() function. After reviewing the code I found the problem
stated in this bug report.

Of course you can say: "No test case - no bug" but I guess this would be a very
naive approach.

There is a similar problem in _M_detach_all() function. It iterates through
list of iterators without obtaining lock.

To be honest, I don't think this code has been designed with thread safety in
mind. Fixing it completely after the fact is going to be very complex, I'm
afraid. I'll try to spend some more time on those issues, but if Doug, the
original author, doesn't provide any special hint, I'm afraid we have to live
with that or even, for consistency, remove the minimal MT support currently
present and add something clear to the documentation.

... that said, if we don't care *at all* about performance, fixing MT-safety
bugs in the _Safe_sequence or _Safe_iterator functions it's easy, just use
everywhere the iterator_base_mutex. The nasty correctness problems are those
involving the templatized _Safe_iterator functions, which of course are not in
debug.cc.

About _M_detach_all specifically, it's called only by ~_Safe_sequence_base(),
thus only when the container itself is destructed. Therefore, I don't think it
may cause problems in practice.

Unfortunatelly it may. Suppose there are two threads: consumer/producer where
producer is creating container, taking iterator to the container and passing
the container to consumer thread.  Consumer thread is simply deallocating the
container - thus calling _M_detach_all function. At the same time iterator
destructor is called which causes SIGSEGV.

We actually encountered this problem - this is not taken from code review only.

Again, adding a mutex to that those *_base functions it's trivial. Now, please
start preparing reduced testcases for such issues, because apprently you *know*
how to do that. The approach "No test case - no bug" maybe can be considered
"naive" as you say, on the other hand enforcing it eventually makes for sound
software engineering, because would be even more naive to rely on submitter
itself and no one else in the world to test a candidate fix, thus not being
able to avoid regressions at a later stage within the project.

I tried to prepare a simple testcase but without any success. It seems to be
extremely hard to hit the moment when pointers are actually changed. Trivial
programs do not reveal the problem.

Ok, but you should try harder, because often in the past we managed to prepare
complete testcases for races and generally MT issues too, which seemed very
tricky at the outset.

For the last issue, can you try this patch? If it works, then probably we can
incrementally commit something similar, because it's decently clean and the
performance should not be affected, even slightly improved.

This is encouraging, that you attempted it. To be clear: we just need something
that we can use to reproduce it. Please try for a complex or big testcase then,
and we'll try to reduce it ourselves.

We have many testcases that reproduce races. See testsuite/threads.

Draft patch using the _M_get_mutex idiom for _M_invalidate

This one, instead, using the _M_get_mutex idiom (similarly to pool_allocator,
for example), should be able to deal with the _M_invalidate issue too. Agreed,
in debug-mode performance isn't the main concern, still I'm a bit worried,
because we have got one single mutex for the entire STL. But I have no idea how
this problem can be solved at this stage, the ABI still frozen. Besides that
general issue, the approach should work, maybe locking is needed also for some
_Safe_sequence functions: in that case _Safe_iterator_base::_M_get_mutex would
be still usable, being public, or, to be cleaner, an _M_get_mutex method could
be added to _Safe_sequence_base too. In any case, I would rather wait for
testcases before touching _Safe_sequence...

Benjamin, what do you think?

I think we are totally misunderstood here. I don't have time to prepare complex
test cases revealing problems not in my code. I have found the bug I even found
the cause of the bug and it is still not enough for you.

If you don't want to be informed about problems in stl then what is this
bugzilla for?

I have already made a workaround in my code to avoid the debug container in
certain situations so it's not me who will actually benefit from the fix.
I reported this issue to help other developers who might encounter similar
problem.
Because of version policies in my company probably I won't be even able to use
your fix.

No, no, there is something *completely* different to it. Sorry, but I'm now
convinced that you are here with the *wrong* spirit, aren't technical matters
to divide us. At all. Did you ever read any of Stallman' papers? Try, just a

All the functions working on a set of _Safe_iterators fixed

In my present understanding *all* the functions belonging to
_Safe_iterator_base, _Safe_iterator, _Safe_sequence_base, and _Safe_sequence
going through a full set of iterators attached to a container are currently
weak wrt the scenario presented in this PR, where _M_detach is called by
iterator destructor. This new draft patch reflects that, consistently. I'm
currently testing it, so far everything seems ok on x86-linux and ia64-linux
four-way.
