    • Milestone 1

      • On Android x86 Focus and Fenix CI startup tests have failed due to a seccomp panic after a `recvmmsg` call.

        • Upstream bug discussion https://github.com/quinn-rs/quinn/issues/1947

        • Accepted upstream fix https://github.com/quinn-rs/quinn/pull/1964

        • Refined upstream fix after conversation with other `quinn` users on minimum supported Android version https://github.com/quinn-rs/quinn/pull/1966

      • On Firefox Nightly Windows we have seen multiple crash reports where `neqo-udp` fails to handle empty datagrams.

        • Fix has landed in mozilla-central through Neqo v0.8.2 release. 

      • On Firefox Nightly Linux x86-64 we have seen multiple crash reports due to a seccomp panic after a `recvmmsg` call.

        • This is due to users running `network.http.network_access_on_socket_process.enabled`, i.e. running the socket thread in a separate sandbox process 

        • Patch accepted and landing https://phabricator.services.mozilla.com/D219110.

    • General

      • Upstream Rust libc has merged Petr Sumbera's fixes for Illumos/Solaris

        • This is needed to run quinn-udp on Solaris.

        • See also discussion with Petr  and quinn pull request.

      • Discussed minimum supported Android API level with quinn folks.

        • Adjusted CI tests accordingly 

        • Quinn-udp will support Android 4, Firefox supports Android 5
