1:18.70 GECKO(2867385) ==================

Again, not sure if this is a problem in usrsctp or in the way that we're using it. Another case that hints we should stop using usrsctp from more than one thread.

Blocks: mochitest_media_tsan

Just saw a variant of this that happens between STS and one of libusrstcp's threads, so it does not look like we can work around it with tighter threading on our side. We're racing on this flag field here: https://searchfox.org/mozilla-central/rev/d6d8fcc22c3820f2ae08229e0d37be19fba74db9/netwerk/sctp/src/netinet/sctp_usrreq.c#819 vs https://searchfox.org/mozilla-central/rev/d6d8fcc22c3820f2ae08229e0d37be19fba74db9/netwerk/sctp/src/netinet/sctputil.c#1527

Any ideas here?

Flags: needinfo?(tuexen)

Also have observed this with sctp_iterator_work racing with sctpconn_connect.

Let me look into that.

Flags: needinfo?(docfaraday)

No, I don't think so.

Nope. We're waiting on a fix from libusrsctp.

It appears that this is fixed in the latest libusrsctp, which we will update to in bug 1795697.
