Fredrik Hallenberg commented on PROTON-2543:
--------------------------------------------
Unfortunately my reproducer is part of a large system so I am currently not
able to provide it. However running it with debug build should be easy. I will
try it asap.
What is rr?
> Crash in epoll.c resched_pop_front
> ----------------------------------

> Key: PROTON-2543
> URL: https://issues.apache.org/jira/browse/PROTON-2543
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Reporter: Fredrik Hallenberg
> Assignee: Clifford Jansen
> Priority: Major
> Attachments: qpid-epoll-crash.patch
>
>
> During stress testing it is fairly easy to reproduce a segfault in
> resched_pop_front. Using gdb it is easy to see that polled_resched_front can
> be zero when entering this function which causes the value to wrap and then a
> crash in later calls.
> polled_resched_front is not checked when calling this function in one
> instance, the trivial fix to check this value is seen in the attached patch
> seems to work.
> Tested with Qpid Proton C++ 0.37.
