Public bug reported: 4.10 kernel is commonly used for test BBR Congestion Control deployments.
Recent 4.13 release had a bunch of fixes for the initial BBR release, namely: 4aea287e90dd61a48268ff2994b56f9799441b62 tcp_bbr: cut pacing rate only if filled pipe f19fd62dafaf1ed6cf615dba655b82fa9df59074 tcp_bbr: introduce bbr_bw_to_pacing_rate() helper 79135b89b8af304456bd67916b80116ddf03d7b6 tcp_bbr: introduce bbr_init_pacing_rate_from_rtt() helper 1d3648eb5d1fe9ed3d095ed8fa19ad11ca4c8bc0 tcp_bbr: remove sk_pacing_rate=0 transient during init 32984565574da7ed3afa10647bb4020d7a9e6c93 tcp_bbr: init pacing rate on first RTT sample All of them marked as 'Fixes: 0f8782ea1497 ("tcp_bbr: add BBR congestion control")', which makes them legitimate bugfixes. All of them constrained to `net/ipv4/tcp_bbr.c` and should be trivial to cherrypick into 4.10. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1708604 Title: Backport recent bbr bugfixes to 4.10 kernel Status in linux package in Ubuntu: New Bug description: 4.10 kernel is commonly used for test BBR Congestion Control deployments.
