Fix potential use-after-free in `when_all_vector` #966

msimberg · 2024-01-15T14:48:59Z

If the call to the last child operation state of when_all_vector actually releases the when_all_vector operation state, the access to the number of predecessors from the when_all_vector operation state will be on freed memory. This PR reads the number into a stack-local variable before starting the child operation states and introduces a test that triggers the failure without the fix.

The valgrind CI configuration shows the following error now, confirming that the new test triggers the failure:

is a test/semantics issue, rather than a clear bug. It's triggered by this test:

pika/libs/pika/execution/tests/unit/algorithm_ensure_started.cpp

Lines 176 to 182 in eaae472

    
           { 
        
               auto l = std::make_shared<pika::latch>(2); 
        
               auto s = ex::schedule(ex::std_thread_scheduler{}) | 
        
                   ex::then([l]() { l->arrive_and_wait(); }) | ex::ensure_started(); 
        
               ex::start_detached(std::move(s)); 
        
               l->arrive_and_wait(); 
        
           }

. I think what's happening is that the start_detached operation state may be released after main exits because the std::thread created by std_thread_scheduler isn't joined before main exits. I'll ignore the failure in this PR as it's not a new failure, and try to think of a way to restructure the test separately.
