The fixes can be found at the latest tagged release: https://github.com/google/bbr/releases/tag/v2alpha-2021-01-15 The changes since yesterday's release: (1) a bug fix for the warning that has been reported by a few users: WARN_ON_ONCE(bbr->prior_cwnd =3D=3D 0); (2) a fix for a compilation error caused for users of the following .config option: CONFIG_BPF_SYSCALL=3Dy (3) enabled the .config option CONFIG_BPF_SYSCALL=3Dy to catch further issu= es of this kind best, neal ps: as always, you can find the instructions to download and build Linux TCP BBRv2 alpha here: https://github.com/google/bbr/blob/v2alpha/README.md On Thu, Jan 14, 2021 at 6:03 PM Neal Cardwell wrote: > > Hi all, > > By popular demand, we have rebased the BBRv2 v2alpha branch from 5.4 to 5= .10. > > The BBRv2 code in this release should be functionally identical to the pr= evious release, since in this rebase we only made the minimal changes to th= e BBRv2 and TCP patches necessary to get the code to compile. > > There were two changes of note we incorporated during the rebase.
