Sadly, we've already workedaround that problem with a custom-built
module. Let me see if my colleagues can test the kernel.

Hi @savetherbtz,

Could you please verify the fix with the Zesty kernel currently in

I'm setting the Xenial task to invalid, since these patches are only for
4.10. Xenial/hwe kernel will get these patches automatically.

2017-10-18 Thread Kleber Sacilotto de Souza 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
zesty' to 'verification-done-zesty'. If the problem still exists, change
the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  Backport recent bbr bugfixes to 4.10 kernel

Status in linux package in Ubuntu:
  Opinion

Bug description:
  4.10 kernel is commonly used to test BBR Congestion Control
  deployments.

  Recent net-next pull in 4.13-rc1 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.
