• What is the status of D16851? thj@ works on it and you are waiting for feedback from bz@.
• rscheff@ is improving AccECN code: D36303.
• glebius@ retiring suppression of random ports allocation https://reviews.freebsd.org/D37042.
• Serious data corruption bug in 13.1 PR 265588 glebius@ is in touch with another guy who reproduces it. This bug is already fixed in stable/13. rscheff@ will contact re@ regarding issuing an EN.

• D37061glebius@ works on simplifying INP_DROPPED.
• D23230 is implementing ECN++.
• D28822 improves PRR, needs some cleanup.
• glebius@ wants feedback on D35199. bz@ isn't fine with it…
• netstat does not support reading connection information from a core file anymore. tuexen@ will document that in the man-page.
• tuexen@ wants to write a tool which dumps the BBLog information of a TCP endpoint from a life system or a core. Using kvm_read() has drawbacks as glebius@ pointed out, using a python kgdb script may be an alternative. tuexen@ will think about it.
• rscheff@ will add some ECN stat counter to the TCP_INFO option. glebius@ will contact re@ about the handling of adding/using padding fields.
• glebius@ wants to remove INP_DROPPED. This will allow using socket options on sockets in TIMEWAIT and CLOSED state. In particular, this will allow using tcpsso on these socket options.
• jtl@ suggested to reduce the MSL value used to control the TIMEWAIT state. It was discussed to use a maximum RTT instead. tuexen@ will add the tracking of the maximum RTT and make this algorithm used when the sysctl-variable net.inet.tcp.msl is set to zero. In a separate the default of the sysctl-variable net.inet.tcp.msl will be changed to zero. tuexen@ will also reach out to the TCPM working group to see what other implementations do.
• It was discussed whether the TCP_LOG socket option should be inherited from the listener. jtl@ said that this should be the case, but interaction with the sysctl-variable net.inet.tcp.bb.log_auto_ratio should be taken into account. tuexen@ will look at it and add jtl@ as a reviewer.
