14 July 2016 Hangout

The long fixes will be committed after the last few are reviewed by Lawrence

gnn still needs to get Mike Karels on the call

Hiren will upload the BSDCan notes

QLogic fix from rstone

gnn will look at how CAIDA scrubs pcaps. pcaps will be shared in the Wiki and Bugzilla

Performance Oriented Congestion Control (PCC) now being looked into by Macy. Lawrence points out that this is only useful for long lived flows. As an idea Lawrence this looks like a good one.

Another idea is to share the host cache among hosts.

More work needs to be done to improve the route cache based on the stats.

We need an overall design for sharing TCP information among several consumers in the kernel.

ip6_output() always calls the TCP host cache? [Drew points this out] An email will go out to bz@

rstone and Macy are trying to make tcp_output() not hold the INP lock for as long as we do currently. This effects high performance links, those over 40Gbps with bi-directional data.

review of integrating EBR for some callout fixes

randall has a patch that reduces locking in the callout system by lining up the TCP code with the callouts https://reviews.freebsd.org/D7136

bz points out that gleb's latest callout fix is till panicing and may put other TCP callout testing “at risk”
