===== Discussion ===== * Any update on blackhole detection? * No update on implementation within our tree. * Gorry may be interested in improving the RFCs on blackhole detection. * Update on the interesting problem with packet lookup returning the wrong TCB which tuexen@ reported at the last call. This is a regression due to epoch. * [[https://reviews.freebsd.org/D18954|D18954]], [[https://reviews.freebsd.org/D18982|D18982]], and [[https://reviews.freebsd.org/D19118|D19118]] are now committed. * One patch got missed during refactoring: after idle, ssthresh is the max of former ssthresh or 3/4 of the former cwnd. This is in [[https://reviews.freebsd.org/D22438|D22438]]. rrs@/jtl@ recommend a sysctl and/or socket option so people can test with this and then decide whether to use it. * Richard has Accurate ECN support refactored into several reviews: [[https://reviews.freebsd.org/D22426|D22426]], [[https://reviews.freebsd.org/D22428|D22428]], [[https://reviews.freebsd.org/D22429|D22429]], [[https://reviews.freebsd.org/D22436|D22436]]. rrs@/jtl@ request that Accurate ECN bits move to t_flags2 instead of using spare bits in t_flags. (It will conflict with other patches in progress.) ===== Next Meeting ===== Next meeting is 5 Dec 2019 @ 1400 UTC.
