https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #20 from Stuart Haslam --- I don't think this bug should be closed. We've never regularly seen it in CI but it's still fairly easily reproducible using the sequence in comment #10, and we think we know the root of

[lng-odp] [Bug 1615] odp_timer fails in CI with Segmentation fault

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #13 from Stuart Haslam --- In my case the tp in the signal handler is a valid timer pool pointer, or at least it was a short time ago, so it's stale rather than corrupted. Commenting out the odp_shm_free() in

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #15 from Ola Liljedahl --- Synchronize with what? We don't know if there is any timer signal in-flight. If we could inject our own signal into the kernel signal queues, we could wait for that signal to be handled

[lng-odp] [Bug 1615] odp_timer fails in CI with Segmentation fault

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #16 from Stuart Haslam --- I thought about just setting some flag in odp_timer_pool_del and waiting for the next timer expiry to action on it, but assuming that it's possible for there to be more than 1

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #17 from Bill Fischofer --- To properly clean up the following is required. 1. Be able to quiesce the context so that no new events will be accepted by the APIs. 2. Modify the context so that it tracks the

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #18 from Ola Liljedahl --- We don't want the periodic timer thread to perform the teardown (as some unspecified time). The teardown needs to be complete (all resources freed) when odp_timer_pool_destroy (?)

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #12 from Ola Liljedahl --- Perhaps we should add an explicit check that the sigval pointer is correct. Add a field with some magic value to the timer pool and check that tp->magic has the expected value. -- You

https://bugs.linaro.org/show_bug.cgi?id=1615 --- Comment #10 from Stuart Haslam --- I'm still seeing this occasionally, but I'm able to provoke it reliably like this; ulimit -c unlimited rm core while true; do ./test/validation/timer/timer_main; [ -f core ] && break;

I seem to be able to generate this fairly reliably. Here's what gdb shows: core was generated by `./timer_main'. Program terminated with signal SIGSEGV, Segmentation fault. #0 odp_atomic_fetch_inc_u64 (atom=) at ./include/odp/atomic.h:158 158 return __atomic_fetch_add(>v, 1,
