Not seeing anything related to webrtc in these failures...

Comment 4

[Jens Stutte [:jstutte]]

Should EventSource get its own mutex for restricting access to its members (currently I see only a mutex for EventSourceImpl) ?

and should probably be a different bug.

Comment 21

[Jens Stutte [:jstutte]]

As stated by the comment mWorkerRef seems to be designed to be accessed only on the worker thread but it can be apparently dereferenced on some other thread through EventSourceImpl::Dispatch.

We might better want to pass a RefPtr<ThreadSafeWorkerRef> to the WorkerRunnableDispatcher and keep and/or dereference it there after a nullptr check?

Hi Yulia, I see WorkerScriptLoader::CancelMainThread in the recent spike's instances, is this something related to your recent work in bug 1783190 ? Thanks!

Comment 28

[Yulia Startsev [:yulia] OOO until July 2026]

It appears to be related, I should have a patch up soon.

Comment 29

[Yulia Startsev [:yulia] OOO until July 2026]

I think the most recent failures should be resolved by D156943

Comment 31

[Daniel Veditz [:dveditz]]

This should have been made a security bug when originally filed, though the signature this is filed on is incredibly generic and appears to have represented different actual bugs over time. Our intermittent filer system needs to have something like the "skip lists" we use in Socorro. In fact, quite likely the exact same list would work.

Generically we assign sec-moderate to TSAN races unless we know more about the exploitability in non-TSAN builds. I added a couple of See-Also bugs that appear to be the same as the recent spike of this signature coming from workers (see attachment 9294051 [details]), and those have rated sec-high. Those are expected to be resolved soon and future intermittents with this signature may or may not be sec-high so I'll stick with sec-moderate here.

It would be best to RESOLVE this bug when the spike is fixed and then open a NEW bug if this signature shows up again unless the stack is more similar. See comment 15 about another spate of detections here that were actually a separate bug.
